In most of the companies heavy loads were moved either with help of cranes or conveyors. The conveyors are cheaper and it is suitable for small scale industries. These conveyors are constrained and can move the load in only one direction. In this project an effort has been put forth to design a multidirectional conveyor with help of ball bearings which can handle the load at different directions. Floor conveyor consists of ball bearings & shaft that makes the load to move at any directions. In olden days logs were used to move heavy loads from one place to another we developed those concept further and found conveyors, further improvement leads to the floor conveyor with multidirectional movement. Multidirectional is achieved by amalgamation of two ball bearings which is connected by a small shaft.

It is not obvious to adjust the speed of a conveyor belt so that it is possible to optimize the transport for each piece conveyed even with various studies presented in this area. The complex methodologies that are shown and the many adaptations indicated in these studies may contribute to the low adoption of these configurations. A study made, in this work, from videos of advertisements showing belt conveyor in operating on the factory floor which presented only 44% efficiency. In this work, it was shown, through theoretical studies, a mathematical model that presents the relationship between the speed and the transport capacity of conveyor belts. Based on a model, a graphical method (using templates) has been proposed that helps in choosing the conveyor belt speed for most efficient configurations that can be identified and adopted simply and without many adaptations to the system as a whole.

Conveyor belts are used widely to carry and transport various materials ranging from fertilizers to foods items from the cargo ship to the packaging site. Spillage and carryback problems are common issues relating to transportaion of these types of materials at Malaysian ports. This leads to lots of wastage in fertilizers and food. In addition, extra manual labour work is required to shovel the spillage into the container. This raises the concern of hygiene especially when relating to food items. Furthermore, improper washing and drainage system has also lead to corrosion on the floor. This has resulted in a lot of inefficient work and lack in productivity in the material handling system. Therefore, in order to solve this problem, primary and secondary belt cleaners were designed using CATIA software. These newly improved simple and cost effective designs of the primary and secondary belt cleaners together with a spray shaft and efficient washing box were fabricated, tested and implemented successfully. The spillage was eliminated and with the new washing system, corrosion on the floor can be prevented from occuring in the future.

Full textAbstract:
For two large beef processing plants, one located in the southern United States (plant A) and one located in the northern United States (plant B), prevalence of Escherichia coli O157:H7, Listeria spp., Listeria monocytogenes, and Salmonella was determined for hide, carcass, and facility environmental samples over the course of 5 months. The prevalence of E. coli O157: H7 (68.1 versus 55.9%) and Salmonella (91.8 versus 50.3%) was higher (P < 0.05), and the prevalence of Listeria spp. (37.7 versus 75.5%) and L. monocytogenes (0.8 versus 18.7%) was lower (P < 0.05) for the hides of cattle slaughtered at plant A versus plant B. Similarly, the prevalence of Salmonella (52.0 versus 25.3%) was higher (P < 0.05) and the prevalence of Listeria spp. (12.0 versus 40.0%) and L. monocytogenes (1.3 versus 14.7%) was lower (P < 0.05) for the fence panels of the holding pens of plant A versus plant B. The prevalence of E. coli O157:H7 (3.1 versus 10.9%), Listeria spp. (4.5 versus 14.6%), and L. monocytogenes (0.0 versus 1.1%) was lower (P < 0.05) for preevisceration carcasses sampled at plant A versus plant B. Salmonella (both plants), Listeria spp. (plant B), and L. monocytogenes (plant B) were detected on fabrication floor conveyor belts (product contact surfaces) late during the production day. For plant B, 21 of 148 (14.2%) late-operational fabrication floor conveyor belt samples were L. monocytogenes positive. For plant B, E. coli O157:H7 and L. monocytogenes were detected in preoperational fabrication floor conveyor belt samples. Overall results suggest that there are regional differences in the prevalence of pathogens on the hides of cattle presented for harvest at commercial beef processing plants. While hide data may reflect the regional prevalence, the carcass data is indicative of differences in harvest practices and procedures in these plants.

In the present paper, the presence of Salmonella spp. in the egg-laying hens producing plants in Thessaloniki area was studied. In total, 2.230 eggshell samples, 588 samples surfaces from floor, walls, conveyor belts, utensils and packaging areas, 168 feed samples and 68 water samples were examined. The survey showed that the rate of contamination in the eggshells was 0.29-3.29% (mean value 1.65%). The contamination rate of the surrounding area of the cages (floor, walls, conveyor belts) and the surfaces in the packaging areas were 6.81% and 7.58% respectively. The feed was contaminated at a rate of 0-6.6% (mean value 4.2%), while all the water samples were free of Salmonella spp. Eighty-six strains of Salmonella were isolated belonging to the S. enteritidis serotype (76.8%), S. bredeney (20.29%) and S. Heidelberg (2,3%). The high prevalence of S. enteritidis, in contrast to the other serotypes, isolated from the eggshells, from the area of the egg producing plants and the feed, showed that strict preventive measures should be applied for the protection of public health and the avoidance of dispersion of Salmonella in the environment.

The aim of this research is to demonstrate the ergonomic process modeling and simulation of manual assembly work through virtual assembly approach in order to present workplace and process improvement prior to their physical prototyping. In this regard, a case study has been carried out to analyze an assembly workplace of a diesel engine by ergonomics simulation and virtual assembly approach. DELMIA, a software tool, has been exploited for the ergonomic simulation and analysis in virtual assembly environment. The case study demonstrates several improvements in the ergonomics of the operators performing assembly on production line of the diesel engine. The assembly process of last few stations of the diesel engine simulated and analyzed on DELMIA in order to exhibit the advantages of the virtual assembly approach to the workplace deign and saving of process time and energy expenditure of operator. On last station of the engine assembly line, parts are assembled relatively at higher and complex positions and it is difficult for an operator to assembly them. Since, the assembly is carried out on conveyor; it is not convenient to change the height of conveyor to overcome the problem. Therefore, height of the floor of last work station is altered / increased. In order to achieve the increased floor height, a number of benches of variable heights are placed on the floor on the last working station one by one in the simulation environment and simulation of the process is carried out. The simulation results show that the ergonomics of operators have significantly changed by altering working height of the operator. Simulation of second last and other working station has also been performed by altering the height of the floor, but no improvements in the ergonomics of the operator observed for these stations

Full textAbstract:
In a fully mechanized coal-mining face, the positioning and attitude of the shearer and scraper conveyor are inaccurate. To overcome this problem, a joint positioning and attitude solving method that considers the effect of an uneven floor is proposed. In addition, the real-time connection and coupling relationship between the two devices is analyzed. Two types of sensors, namely, the tilt sensor and strapdown inertial navigation system (SINS), are used to measure the shearer body pitch angle and the scraper conveyor shape, respectively. To improve the accuracy, two pieces of information are fused using the adaptive information fusion algorithm. It is observed that, using a marking strategy, the shearer body pitch angle can be reversely mapped to the real-time shape of the scraper conveyor. Then, a virtual-reality (VR) software that can visually simulate this entire operation process under different conditions is developed. Finally, experiments are conducted on a prototype experimental platform. The positioning error is found to be less than 0.38 times the middle trough length; moreover, no accumulated error is detected. This method can monitor the operation of the shearer and scraper conveyor in a highly dynamic and precise manner and provide strong technical support for safe and efficient operation of a fully mechanized coal-mining face.

Full textAbstract:
To improve the resource recovery efficiency of mining face in thick coal seams, the correlation between deformation failure of bottom coal in the gob-side entry and coal pillar width was analyzed by theoretical analysis, numerical calculation, and similar simulation experiments. The results showed that, when the coal pillar was strong, with the decrease of pillar width, the failure depth of the bottom coal in the gob-side entry and floor heave increased. The deformation failure depth of the bottom coal in the entry was inversely related to the width of the coal pillar. The bottom coal was further fractured and dispersed under the action of tension, shear, and extrusion in the process of floor heave. Based on the floor heave induced by the narrow coal pillar, a recovery technique of the bottom coal with thick coal seams in the gob-side entry was developed. The width of the narrow pillar to be reserved was obtained by theoretical calculation and revised by numerical simulation; ultimately, the reasonable width was determined. Under the complex stress of the narrow pillar, the bottom coal in the gob-side entry was fully heaved, cracked, and separated. To realize the comprehensive mechanization and resource recovery of bottom coal, a matching mining excavator loader, transfer conveyor, and retractable belt conveyor were selected to transport the crushed bottom coal in the entry. This method has been successfully applied to the return airway of working face 8407 in the No. 5 Coal Mine of Yangquan Coal Group with remarkable economic and social benefits.

Full textAbstract:
With regards to the low degree of digitization, lack of real geological terrain, and low degree of automation in the cutting process of the traditional virtual fully mechanized mining face, we studied the key technologies of virtual operation and cutting path planning of the shearer on the three-dimensional (3D) roof and floor based on the virtual reality engine (Unity3D). Firstly, the virtual 3D coal seam was constructed through the 3D geological coordinate data of the mine. On this basis, the shape function of the scraper conveyor with the adaptive configuration on the floor was constructed to obtain the combined operation of the virtual shearer and the scraper conveyor. The movement of the shearer’s walking and height-adjustment was then, analyzed. A strategy for automatic height-adjustment based on the adjustment of the direction of the drum movement is hence, proposed to control the cutting path of the shearer. Finally, different experimental schemes were simulated in the developed prototype system after which each of the schemes was evaluated using the fuzzy comprehensive evaluation method. The results show that the proposed strategy for trajectory control can improve the accuracy and stability of the shearer’s motion trajectory. In Unity3D, the pre-selected schemes and digital and visual planning of coal production are previewed ahead of time, the whole production process can be mapped synchronously in the production process. It is also obtained that the virtual preview and evaluation of the production process can provide some guidance for actual production.

The process of spraying varnish is an important part of this industry but it still uses minimal tools so that this process has several obstacles, namely wasted time, unreliable work positions, frequent defects, and disturbed other work stations. To overcome this, a varnish sprayer has been designed, but there are still many things that need to be improved in terms of shape. The research was conducted at SMEs AAT RATTAN CHANDY CRAFT which is engaged in rattan handicrafts such as chairs, tables, serving covers. From the data obtained, 21 out of 28 people experienced complaints in the arms and hands due to less ergonomic work positions and tools. This study uses the Macroergonomic Analysis and Design method, in order to obtain a varnish spray design proposal in the form of a rectangular, faceted iron frame, the main drive of the dynamo (motor), the belt rope as a power connector, the conveyor as a spraying route, the spray gun as a sprayer. The dimensions of this varnish sprayer are 230 cm high, 200 cm wide and 500 cm long. In the proposed working method, there must be two operators, the first operator at the input door of the lifting tool and putting the product on the conveyor, the second operator receiving at the output door of the tool. This eliminates bending and squatting activities because the conveyor height is made as high as 137 cm from the floor surface.

Abstract. In-field presorting of apples, in combination with the harvest aid function, would have advantages of cost savings in postharvest handling and storage, reduced postharvest pest and disease problems, and better inventory management, while also enhancing harvest productivity. A new apple harvest and in-field presorting prototype was developed to help apple growers achieve these potential benefits. The prototype sorts and grades fruit based on color and size, using a machine vision-based sorting system with an innovative fruit singulating and rotating design (SRD), and it handles the graded fruit in the bins using newly designed automatic bin fillers. Bruise damage by impact is a critical factor in the development of the apple harvest and in-field presorting prototype. This article reports on the major design features of the prototype and experimental evaluation of the prototype for potential bruise damage. Experiments were conducted on ‘Gala’ and ‘Fuji’ apples to evaluate bruise damage potential under both empty and partially filled bin conditions. An impact recording device (IRD) was used to measure the impact magnitude in terms of peak acceleration (G) at all critical points of the machine, including harvest conveyors, main conveyor, flat conveyor, SRD, cup conveyor, bin filler, and bins. It was found that bruise damage mainly occurred during bin filling. The number of impacts recorded for the partially filled bin was reduced by 60%, compared to that for the empty bin, indicating that the impact between apples and the wooden bin’s floor was a major cause of bruising. The maximum G value for the partially filled bin was measured at 34.5, while the measured G values were less than 20 from start to the point just before the bin filler, indicating no bruise damage. Bruise evaluation showed that no more than 9% of the test apples would be downgraded from ‘Extra Fancy’ grade for the partially filled bin condition. Higher G values for the empty bin condition suggested the need for further improvement to the discharge of apples from the bin filler to the bin to further reduce bruise damage.

Purpose. carrying out field researches of the conveyor excavation`s state and establishing geomechanical patterns based on the data, that were obtained in the mining and geological conditions of the Krasnolymanska coal mine. Methodology. Mine field researches of the conveyor excavation deformed state, which is under the influence of the longwall face, and moves in time and space, were carried out. The observation was performed by using a measuring station, which included five measuring points. The results of measurements were generalized and the excavation contour deformation features at various stages of mining coal seam were revealed. Results. Dependencies, that characterize the process of coal mass deformation around the mine at various stages of its exploitation. are obtained. During exploitation processes of the conveyor excavation relative to the longwall face, that gradually pass through four geomechanical situations in mining and geological conditions of the Krasnolymanska coal mine, are established – outside influence zone, in the influence zone, within the longwall face, outside the longwall face. These situations differ in the nature of roof and floor deformation, the vertical convergence of which at each stage changes linearly in time and goes to zero at a distance of 23 meters outside the longwall face. These indicators give reason to consider the roof rocks in the longwall as that sink without breaking the continuity, and also to perform the calibration of geomechanical models based on this. Scientific novelty of the research is new patterns establishment of the coal mass deformation, which contain the conveyor excavation, in the process of the coal seam mining in specific mining and geological conditions. Practical value of the research planned to be carried out on the basis of data obtained after field research is allowed to develop a geomechanical model of active methane accumulation zones searching. The model is applied for further industrial use purposes and to improve the safety of coal mining.

This experiment was conducted under commercial conditions to establish the response of various blood parameters to handling in the period immediately prior to slaughter under a variety of conditions.Pigs from four farms were slaughtered at two abattoirs, each with two slaughter handling systems. Pigs at abattoir one were electrically stunned (low voltage, 110v) either in a floor pen (FPl) holding five pigs or in a single pig conveyor restrainer (RR). Pigs were driven in groups of 25 thrQugh a straight race 1.5m wide to FPl. The race system leading to RR consisted of a collection pen holding 25 pigs. This pen was stepped in two places and led to a 10m single file race which fed the restrainer. Abattoir two also had a floor pen system (FP2) with low voltage (11Ov) stunning, and a CO2 dip-lift system (CO2). FP2 was fed by a single file race 7m long with a 90° curve within the first 2m. The CO2 stunner was fed by a circular collection pen 3m in diameter, with a rotating gate moving pigs into a double race 3m long which supplied the dip-lift unit.

Tires, conveyor belts, floor mats, and shoe soles form a main-stream of rubber waste. The amount of these used materials continuously increases due to development of the rubber market. Therefore, pro-ecological utilization (i.e., energy recycling instead of burning) and recovering valuable and recyclable materials becomes an urgent necessity. In this regard, this work was devoted to the chemical recycling of selected used rubber products, and it especially explores the possibility of limonene production. Different types of waste rubber were characterized and pyrolyzed at microgram and laboratory scales, and the results were compared. Additionally, the pyrolysis of tires, the most significant stream of rubber waste, was also conducted in a semi-technical scale reactor. The effectiveness of limonene formation in the liquid fractions obtained from different types of waste rubber was compared.

Full textAbstract:
The development and application of roadway group layout methods in coal mines have become more common and the mutual disturbance of blasting and driving of roadway groups has also become more prominent at depth. To improve the stability of rock mass surrounding roadways, we performed a systematic study on the factors that influence blasting and driving disturbances of adjacent roadways in deep mine roadway groups. We use the dynamic analysis module in FLAC3D to obtain the influence laws of three factors on the disturbance effects of adjacent roadways, namely, excavation methods, layer position changes of the roadway group, and whether or not bolt support is applied in the first roadway. Blasting strongly influences the surrounding roadway and increased horizontal distance can effectively reduce the disturbance effects of blasting and driving between adjacent roadways compared with increased vertical distance. Bolt support of the first excavated roadway enhances the roadway integrity and better stabilizes the rock structure surrounding the roadway. Industrial tests were carried out on three uphill roadways in the Gubei no. 1 mine (6-2). The monitoring results show that the movement of the roof and floor of the floor uphill return wind roadway is larger than that on the two sides. There is no notable change in the deformation speed of the surrounding rock in the floor return air roadway, but the deformation speed of the uphill conveyor belt roadway changes significantly. The results show that when the blasting excavation of a deep mine roadway group is more than five times the tunnel spacing, the increased horizontal distance effectively reduces the disturbance effects of excavation between adjacent roadways, which is consistent with the simulation results.

This article focuses on the emerging supply chain of hardware, software, and engineers transforming warehouses to test bed of innovation for autonomous robots. Although warehouses are controlled environments, they are filled with changing obstacles, traffic, and unexpected surprises. Warehouses used to be the hub of a relatively simple logistics operation. They received and stored pallets of identical goods from manufacturers and importers, and then sent boxes via a conveyor belt or cart to trucks destined for retail outlets. Bruce Welty and his partner have built a world-class e-commerce fulfillment facility, Quiet Logistics, by deploying robots sold by Kiva Systems. The next-generation robots have master control systems to optimize their movements, as do the Kiva robots. However, these new robots are designed to collaborate with human workers rather than banishing them from the aisles, which means the robots must move briskly across the warehouse floor while avoiding people, forklifts, pallets, and boxes. Economics make warehouses a great proving ground for autonomous robots.

Full textAbstract:
Currently, a belt conveyor or an automatic guided vehicle is used as a conveying device in a factory. However, Transportation of the ceiling surface and the wall surface in these devices is impossible. Elevator is used for conveying from the lower floor to the upper floor. Therefore, the conveying device capable of movement on a wall and a ceiling significantly improves the efficiency of work. Based on this background, development of working robots capable of transporting on a wall surface is required. In the present study, the vibration actuator with a very simple structure capable of movement on a magnetic substance by means of the inertial force of a vibration model was again considered. Furthermore, upsizing for the actuator in order to improve the propulsion characteristics was considered. The volume of the permanent magnet constituting the vibration component of the actuator was increased according to the similarity rule. Four models of actuator with approximately equal drive frequency were prototyped and experimentally tested. The experimental results demonstrate that the maximum efficiency of the actuator for a standard model pulling its own weight was 27.1 %. Furthermore, the actuator is able to pull a load mass of 170 g. For the actuator of 5 times model, the actuator is able to climb upward at 9.5 mm/s while pulling a load mass of 3500 g. This actuator is able to propel a load mass of approximately 36 times the weight of the actuator itself.

Due to various architectural and structural requirements, irregularities in the structures are inevitable. In order to determine the behavior of the structure under the effect of the earthquake and to find the relevant cross-sectional effects, the regular or irregularity of the structure of the structure of the structure is significantly effective. Irregularities present in the design cause further strain of the carrier elements. With the increase in the number of floors in earthquake risk regions, curtains are needed in order to ensure sufficient rigidity and strength in the frame systems and to limit the floor displacements. When the shear walls are used together with the frame system in a conveyor system, their stiffness is larger than the columns and they meet a significant part of their horizontal loads such as earthquake and wind. In this study, the effect of shear walls placement on structural behavior in reinforced concrete buildings with H-type irregularity was investigated. For this purpose, 7 models, each of which are 4,8,12 stories and one of which are reference models, have been examined on the irregularity and behavior of the structure in different shear walls settlements. The results obtained by using the İDECAD V7 program and DBYBHY-2007 principles ware analyzed by using 2018 TBDY for 4 storey models from the results found using Sap2000 program and the results were compared. The buildings were evaluated among themselves according to the reference model withhout plan disorder.

Full textAbstract:
The mechanical, electrical, and autonomy aspects of designing a novel, modular, and reconfigurable cleaning robot, dubbed as sTetro (stair Tetro), are presented. The developed robotic platform uses a vertical conveyor mechanism to reconfigure itself and is capable of navigating over flat surfaces as well as staircases, thus significantly extending the automated cleaning capabilities as compared to conventional home cleaning robots. The mechanical design and system architecture are introduced first, followed by a detailed description of system modelling and controller design efforts in sTetro. An autonomy algorithm is also proposed for self-reconfiguration, locomotion, and autonomous navigation of sTetro in the controlled environment, for example, in homes/offices with a flat floor and a straight staircase. A staircase recognition algorithm is presented to distinguish between the surrounding environment and the stairs. The misalignment detection technique of the robot with a front staircase riser is also given, and a feedback from the IMU sensor for misalignment corrective measures is provided. The experiments performed with the sTetro robot demonstrated the efficacy and validity of the developed system models, control, and autonomy approaches.

Biofilms in the food-processing industry are a serious concern due to the potential for contamination of food products, which may lead to decreased food quality and safety. The effect of two detergent and sanitizer combinations on the inactivation of Listeria monocytogenes biofilms was studied. Combination A uses a chlorinated-alkaline, low-phosphate detergent, and dual peracid sanitizer. Combination B uses a solvated-alkaline environmental sanitation product and hypochlorite sanitizer. The survival of bacterial biofilms placed at 4 and 10°C and held for up to 5 days was also addressed. To simulate conditions found in a ready-to-eat meat-processing environment, biofilms were developed in low-nutrient conditions at 10°C (with and without meat and fat residue) on a variety of materials found in a plant setting. Included were two types of stainless steel, three materials for conveyor use, two rubber products, a wall, and floor material. Biofilms developed on all surfaces tested; numbers at day 2 ranged from 3.2 log on silicone rubber to 4.47 log CFU/cm2 on Delrin, an acetal copolymer. Biofilm survival during storage was higher at 4°C (36.3 to 1,621%) than 10°C (4.5 to 83.2%). Small amounts of meat extract, frankfurters, or pork fat reduced biofilm formation initially; with time, the biofilm cell number and survival percentage increased. Cleaning efficacy was surface dependent and decreased with residue-soiled surfaces; biofilms developed on the brick and conveyor material were most resistant. Both detergents significantly (P < 0.05) removed or inactivated biofilm bacteria. The sanitizers further reduced biofilm numbers; however, the reduction was not significant in most cases for the dual peracid. Using a benchmark efficacy of >3-log reduction, combination A was only effective on 50.0% of the samples. Combination B, at 86.1%, was more effective.

Cross-contamination of fresh-cut leafy greens with residual Escherichia coli O157:H7–contaminated product during commercial processing was likely a contributing factor in several recent multistate outbreaks. Consequently, radicchio was used as a visual marker to track the spread of the contaminated product to iceberg lettuce in a pilot-scale processing line that included a commercial shredder, step conveyor, flume tank, shaker table, and centrifugal dryer. Uninoculated iceberg lettuce (45 kg) was processed, followed by 9.1 kg of radicchio (dip inoculated to contain a four-strain, green fluorescent protein–labeled nontoxigenic E. coli O157:H7 cocktail at 106 CFU/g) and 907 kg (2,000 lb) of uninoculated iceberg lettuce. After collecting the lettuce and radicchio in about 40 bags (~22.7 kg per bag) along with water and equipment surface samples, all visible shreds of radicchio were retrieved from the bags of shredded product, the equipment, and the floor. E. coli O157:H7 populations were quantified in the lettuce, water, and equipment samples by direct plating with or without prior membrane filtration on Trypticase soy agar containing 0.6% yeast extract and 100 ppm of ampicillin. Based on triplicate experiments, the weight of radicchio in the shredded lettuce averaged 614.9 g (93.6%), 6.9 g (1.3%), 5.0 g (0.8%), and 2.8 g (0.5%) for bags 1 to 10, 11 to 20, 21 to 30, and 31 to 40, respectively, with mean E. coli O157:H7 populations of 1.7, 1.2, 1.1, and 1.1 log CFU/g in radicchio-free lettuce. After processing, more radicchio remained on the conveyor (9.8 g; P < 0.05), compared with the shredder (8.3 g), flume tank (3.5 g), and shaker table (0.1 g), with similar E. coli O157:H7 populations (P > 0.05) recovered from all equipment surfaces after processing. These findings clearly demonstrate both the potential for the continuous spread of contaminated lettuce to multiple batches of product during processing and the need for improved equipment designs that minimize the buildup of residual product during processing.

Damage to structures may occur due to irregularities and other effects on reinforced concrete structures. Due to the earthquake zone, the buildings to be designed in our country should be designed according to the earthquake loads. In this study, the effects of the location and directions of the shear walls on the earthquake loads in the case of discontinuity in reinforced concrete buildings were examined. In this study, the effect of curtain placement on structural behavior in reinforced concrete buildings with U type plan irregularity was investigated.In order to determine the behavior of the structure under the effect of the earthquake and to find the relevant cross-sectional effects, the regular or irregularity of the structure of the structure of the structure is significantly effective. Irregularities present in the design cause further strain of the carrier elements. With the increase in the number of floors in earthquake risk regions, curtains are needed in order to ensure sufficient rigidity and strength in the frame systems and to limit the floor displacements. When the shear walls are used together with the frame system in a conveyor system, their stiffness is larger than the columns and they meet a significant part of their horizontal loads such as earthquake and wind.In this study, the effect of shear walls placement on structural behavior in reinforced concrete buildings with U-type irregularity was investigated. For this purpose, 7 models, each of which are 5,10,15 stories and one of which are reference models, have been examined on the irregularity and behavior of the structure in different shear walls settlements. The results obtained by using the İDECAD V7 program were compared with the results analyzes were made using the principles of TBDY 2018 and the results were reached.

This study was undertaken to explore environmental sources of Listeria monocytogenes in a commercial chicken further processing facility and to compare the isolates obtained from this facility with others obtained from fully cooked product. In a survey conducted at the processing facility, 40 environmental sites (encompassing two production lines and representing areas in which raw and cooked products are processed) were cultured for L. monocytogenes. The resulting isolates were subjected to molecular subtyping by ribotyping, and these isolates were compared with 25 isolates collected by plant personnel from product contact surfaces and from fully cooked product. Eighty-nine environmental and product isolates were divided into 15 distinct ribogroups. Two ribogroups included isolates from fully cooked product; the members of these two ribogroups were subjected to further analysis by pulsed-field gel electrophoresis, resulting in four clusters. L. monocytogenes isolates from fully cooked product produced on line 1 were found to be indistinguishable from isolates collected from (i) drains on the raw-product side of line 1 and (ii) the floor surface in the cooked-product area of line 1. L. monocytogenes isolates from fully cooked product from line 2 were found to be indistinguishable from isolates collected from (i) the spiral freezer exit conveyor on line 2, (ii) raw product contact surfaces on line 1, and (iii) drains in the cooked-product area of line 1. These data suggest that L. monocytogenes can colonize a poultry further processing facility and eventually be transferred to fully cooked product.

Full textAbstract:
Zero-waste is an ambitious goal to encourage sustainable production, consumption optimum recycling and resource recovery. The recycling and resource recovery of chrome-tanned leather waste is a difficult proposition because of the three-dimensional chemical network of collagen, which renders leather waste incompatible to polymer matrices. Many attempts have been undertaken to reuse leather waste, most of them require technological processes and challenging chemical pretreatments, which make the reuse an economically disadvantageous industrial operation. The paper aims to show how a very fine separation of leather solid waste leads to raw materials suitable for mixtures with natural rubber, without any chemical pretreatment. In other words, the paper intends to be a stimulus to manage leather solid waste carefully to start a cleaner and more profitable production. In particular, various industrial compounds containing different concentrations of post-tanning dyeing, or chrome shaving or oil-tanning and natural rubber were vulcanized through a standard preparation. Some compounds were also reinforced with carbon black and the vulcanization kinetics were monitored through rheometer. Experimental results indicate that there exists an optimal concentration of waste such that post-tanning dyeing post-tanning and chrome shaving are suitable for manufacture floor mats, soles and heels while oil-tanning waste can be used for making hose or conveyor belts. The mechanical performances of the articles prepared by direct mixing with leather waste are the same as those of commercially distributed rubber products.

Glass floors require the trading of architectural intuition for faith in the invisible as structural. They heighten the awareness of standing above something; the refraction of glass, conveying a jewel-like preciousness; its reflections, momentary glimpses of solidity. In many in situ archaeological sites, glass floors reveal the gaps between body, weight, and archaeological feature; an awareness of the destructive power of gravity threatening the object of archaeology below. Standing on this “solid” air conveys supernatural levitation, but, at height, can also instil a disconcerting and visceral fear because the floor cannot be seen. The article examines architectural instances of glass, specifically in sites of art, tourism, and archaeology, and predominantly in floors, which suspend occupants above, or at least confuse the relationships between floor, feet, and standing. It is particularly interested in the difficulties of assuming that glass provides an uncomplicated visual relationship between viewers and in situ archaeology.

An automated warehousing system often consists of storage modules, storage and retrieval mechanism, lifting equipment and conveyor systems. These facilities are used to overcome some disadvantages of manually operated warehousing systems which often lead to a high frequency of human errors, high labour cost and low efficiency. The usage of these automated facilities may also be helpful to maximise utilisation of shop floor space and improve efficiency of warehousing operations. On the other hand, at this age of information technology that the access to the internet is just at the fingertip, it has been seen a rising trend for online shopping in the past decade. Thus, manufacturers, suppliers or distributors have been seeking for even more efficient and effective new methods to store and distribute their goods. A number of studies through a literature review suggest that future generation warehouses may be designed and implemented as more centralised and distributed warehousing systems in which customers place their orders on-line and goods will then be dispatched directly to their door steps from these centralised distribution centres. This paper presents a proposal for designing and implementing future generation warehousing systems using fast-growing IT technologies such as radio frequency identification (RFID), wireless sensors and networks. The overall purpose of this study is to develop a conceptual design of an integrated system for future generation automated warehouses by incorporating a new design of storage and retrieval modules with the applications of these IT technologies used for automation activities. The presentation of this paper only highlights the part of this work including a design of a core mechanism for automated storage module namely the cantilever storage racks, which have the feature of scalability and reconfigurability.

Song is a set of phrases that is accompanied by musical rhythms, contain message in the lyrics and can be sung. These days, there are many popular songs that have negative value for listeners. Conveying message about sex, love or portrayal of women is still a social debate because of cultural differences as well as rules in the environment. “Versace on the Floor” was one of the Bruno Mars’ famous song which contain sexual message in its lyrics. In this case, this study aims at discovering of students’ perception on Bruno Mars song “Versace on the Floor” about different gender regarding language used fin the song and allegedly contain elements of sex. This study used qualitative research methods to provide a detailed perspective of people about social phenomena such as culture or song. The researcher used students of University Muhammadiyah Malang as research subjects. The number of participants consisted of 20 female students and 20 male students. This research used questionnaire, interview guideline and document analysis to get data. The result indicated that most of students agreed that Bruno Mars’ song “Versace on the Floor” conveys sexual message. Both female and male students agreed that the song conveyed sexual message (female scored the greater number). However, several students thought that “Versace on the Floor” did not imply sexual message. They thought that it was a romantic song, which was expressed like having sexual message. Moreover, more than a half of the respondents (female scored greater number) thought that “Versace on the Floor” had a good melody. Moreover, the song should not be banned in Indonesia because the song was only heard as entertainment.

Service branding is a particular form of emotional management, where employees are regarded as adaptable media, who can be trained to convey corporate values while interacting with customers. This paper examines the identity work of butchers during the brand revitalisation campaign of Kvickly, a Danish supermarket chain. During the implementation of the “Best Butcher in Town”-project, Kvickly’s shop floor becomes an engineered servicescape where the norms of good salesmanship must be performed. By documenting the disloyal behaviour of butchers, we demonstrate that the affective commitment towards corporate brand values is closely related with self-enactment opportunities of occupational communities. Total service-orientation threatens butchers’ perception of autonomy and may therefore result in the emergence of resistant subcultures.

Abstract. In recent years, flooding has become an increasing concern across many parts of the world of both the general public and their governments. The climate change inducing more intense rainfall events occurring in short period of time lead flooding in rural and urban areas. In this study the flood modelling in an urbanized area, namely Samsun-Terme in Blacksea region of Turkey is performed. MIKE21 with flexible grid is used in 2-dimensional shallow water flow modelling. 1 × 1000−1 scaled maps with the buildings for the urbanized area and 1 × 5000−1 scaled maps for the rural parts are used to obtain DTM needed in the flood modelling. The bathymetry of the river is obtained from additional surveys. The main river passing through the urbanized area has a capacity of 500 m3 s−1 according to the design discharge obtained by simple ungauged discharge estimation depending on catchment area only. The upstream structural base precautions against flooding are modelled. The effect of four main upstream catchments on the flooding in the downstream urban area are modelled as different scenarios. It is observed that if the flow from the upstream catchments can be retarded through a detention pond constructed in one of the upstream catchments, estimated Q100 flood can be conveyed by the river without overtopping from the river channel. The operation of the upstream detention ponds and the scenarios to convey Q500 without causing flooding are also presented. Structural management measures to address changes in flood characteristics in water management planning are discussed.

All these systems must be in mutual harmony and ensure thermal comfort. Ventilation system must use the power of wind, the heated air from the double skin facade, heat recovery system, preheating or cooling in the ground channel. In the summer, there must be used the night natural cooling of building. For the heating is the most suitable to use radiant floor heating (30%) in combination with radiant ceiling heating (70%). The next progressive way is the combination of new concrete core conditioning and floor convector heaters.

Mining transport systems largely determine effectiveness of mining enterprises. The study aim is developing new technical solutions for progressive mining transport systems based on the harmonization of technological solutions and equipment. The aim is achieved through the introduction of new mine transport designs compatible with tunneling machinery, enabling change from cyclic concept of a mining enterprise activity to in-line system concept. The option is considered on development of designs of steeply inclined and curving conveyors in transport workings, including overhead and floor pipe belt conveyors and airdraulic pipeline systems for delivering lump ore from the face to the surface in the mine. At the same time, the basis of the proposed technology and equipment is the method of contactless hard rock breaking by using hydroimpulsive facilities. The proposed solutions allow decreasing mineral mining and processing capital and operating costs.

Ovide Moralisé of the early fourteenth century is much more than a translation into Old French of the first-century Latin Metamorphoses of Ovid. It has long been observed that mediaeval translators were not driven by a passion for "accuracy," or torn by a sense of the futility of their task as their modern counterparts have been. As a comparison of the two texts clearly shows, the mediaeval poet augmented Ovid's work where he found it lacking, displaying an encyclopaedic erudition in the process. The author of Ovide Moralise also adapted the pagan content of Ovid's Metamorphoses to convey Christian dogma to his audience. Every narrative element, every character, and every symbol is employed to represent a Christian significance by means of allegorical exegeses which are as long as or longer than the passages they explicate.

Protection and restoration of historical structure has a big importance to transfer past from future. It is necessary to protect all materials and documents that includes past culture, life style and life art in purpose of human history. Structures that used in past, is most important of these materials. Protection of historical structures that reflect to history of period and is historical artifact is also important because of emphasized reason. There are many historical structures in different region of Turkey. Some structuring especially show all cultural structure of that period and stand erect as grand monument. But in the length of time these type structures abrade and lose their nature, because of natural or other reason. After ever earthquake, almost each historical structures have permanent damages in Turkey which is earthquake area. For this reason, It is necessary to transfer future these historical structures by strength and repairing to discover local earth conditions and equipments that used in structure against to earthquake and other affects, determining damaged condition, determining system of architecture and conveyer to these historical structures On the other side, protection of structure can be provided with help of increasing functionality. Unused and closed historical structure will abrade and because of natural and other affects, it will damages and becomes unused. So, basic protection is to use and repair periodically to these historical structures. In near future, protection and restoration of historical structures get importance in Turkey. Many historical structures start to handle for this propose, works pick up speed for restorations. Mustafa Kemal primary school which used as school long time, and completed construction in 1910 Antalya-Turkey, is other important cultural heritage. Accumulation school building has basement, ground floor, and 1.floor. Because of floor height, basement has not been used. Other two floors have been used for common room, laboratory and toilet. In this work, after building survey of historical building used for school had been taken, equipment used in building had been confirmed and local earth condition had been determined, according to exist Turkish Regulations building analyze had been done. According to lacks of structure, it had been invigorated. For propose of implementation of architecture style to period, all added parts had been restored and renewed to damaged parts.

Purpose – The purpose of this paper is to explore the spatial implications of new learning theories and the use of information and communication technologies (ICT) in higher education. Design/methodology/approach – Based on a review of the literature, a theoretical framework has been developed that visualises the spatial implications of developments in higher education. To further explore spatial configurations that support changes in education, a comparative floor plan analysis was carried out at four Dutch institutes of higher education. Findings – The findings show that the traditional classroom space is progressively being replaced by a variety of learning settings to support contemporary learning activities. Practical implications – The research findings contribute to a better understanding of the alignment of learning space to the evolving needs that come from new ways of learning, supported by advanced ICT, and can be used to support space planning in higher education. Originality/value – This paper builds upon findings from different disciplines: Facilities Management and Corporate Real Estate Management (suitability of floor plans) and Theory of Education (the pedagogical approaches and pedagogical assumptions those floor plans convey).

Full textAbstract:
Abstract The likelihood of floods and other potentially destructive natural phenomena is often expressed as a return period or recurrence interval, such as a 100-yr flood. However, the expression might give users the impression that the event will occur exactly once within the described period, obscuring the intended probabilistic meaning. If so, users may think a flood is less likely when one has just occurred or more likely when it has not, leading to a “flood is due” effect. This hypothesis was tested experimentally in two studies reported here. Participants were given either a return period or a probability expression and asked to rate flood likelihood and concern. Flood recency was also manipulated. The results from both studies support a flood is due effect when the return period expression is used. In the return period condition alone, participants rated floods as more likely and expressed greater concern when no flood had occurred recently. When no likelihood information was conveyed in the control condition, the opposite effect was observed. Participants rated flood likelihood as higher and expressed greater concern when a flood had occurred recently. Participants using the percent chance expression were least affected by flood recency. This adds to the growing body of research suggesting that nonexperts can benefit from probabilistic weather forecasts.

With this instrument we were able to amplify the resonances, physical and beyond, of the institution. In other words, by deploying this instrument we intended to both convey its architecture and conjure its past.

In the newly developed excavation system for construction of basement of building, steel elements plays a role as temporary member before casting floor concrete, but it do behavior as composite beam mixed with concrete after floor slab has been casted. That is, it is necessary to review if axial stress loaded in steel beam can be conveyed properly to slab, as casting concrete slab under conditions of application of compression to the steel beam In this manner, this paper presents the experimental result of the composite beam subjected to both constant axial load and variable vertical load. Main parameters in the test are magnitude and loading time of axial force. As a result, it was found that there was no effect on the flexural strength according to the timing of compression and axial force. The flexural strength of the composite beam subjected to both a constant axial compression and increasing vertical load could be predicted with somewhat safety by using code equations.

As Edward Said, Norman Daniel, and Dorothee Metlitzki have pointed out, the purportedly Muslim figures who appear in medieval western literature usually bear little or no resemblance to historical Muslims of the period. Said states, "we need not look for correspondence between the language used to depict the Orient and the Orient itself, not so much because the language is inaccurate but because it is not even trying to be accurate" (71). Similarly, Daniel and Metlitzki identify repeated stereotypical misrepresentations of Islam in medieval literary texts, such as the depiction of Islam as a polytheistic religion or the depiction of alcohol-drinking Muslims (Daniel 3-4, 49-51, 72-73, 81, 133-54; Metlitzki 209-10). It is certainly true that there is little or no mimetic relationship between literary Saracens and historical Muslims, but it should be noted that literary Saracens, despite their inaccuracies, did connote for the West an extremely powerful, technologically advanced Muslim civilization, which both impressed medieval Christians with its scientific knowledge and immense wealth, and menaced them militarily with its many victories over crusaders and its capacity for territorial expansion. Thus, while the Saracens of western literature may not offer us a historically accurate vision of medieval Islam, they can occasionally offer us some insight into the anxieties historical Islam posed for the West. This essay examines moments in the fourteenth-century Middle English romance Sir Beves of Hamtoun when the text’s depiction of one knight’s assimilation into a Saracen world communicates historical anxieties about how life in a Saracen enclave might compromise the Christian heroism of an English knight. The essay argues that Beves of Hamtoun both conveys a fear of Christian assimilation into a non-Christian world, and defines a model of heroic action to counteract such assimilation and re-establish the borders between Christianity and Saracenness. However, the text also indicates the ways in which heroic efforts to reconstruct such borders might ultimately fail.

In the October 1995 issue of Good Housekeeping, there appears an advertisement for a new "Barbie Collector's Series," featuring for the first time a doll called "Medieval Lady Barbie." Clad in a precious garment of the high Gothic style, this icon of our time is a dramatic representation of how the Middle Ages are perceived in popular culture at the end of the twentieth century. Medieval Lady Barbie is certainly not meant to function as an historically accurate document: she is first of all a toy, one of Mattel's many collector's series toys (compare Ebersole/Peabody 16, and Rand 164), and the use of a medieval garment for this twentiety-century doll illustrates that the Middle Ages have become a kind of treasure trove that can be mined in any way we like; they have become a kind of "queer accessory," as Erica Rand has expressed it in her anthropological study of the Barbie. By using a medieval dress, the maker does not wish to allude to the Middle Ages as a whole; rather, he wishes to play with isolated aspects of the distant era. The dress has a strangely comforting quality about it and an emotional nearness that is both apparent and mysterious. These qualities stem not from the Barbie, nor from the medieval accessory alone, but from the combination. The imagined dialogue between the Middle Ages and the twentieth century should convey an assurance to the modern reader that, amidst all the social, cultural, and political chaos present at the dawn of the twenty-first century, there are constants in our cultural understanding of ourselves, in our cultural identity. The reality, of course, is that there is no dialogue going on. The Middle Ages has its twentieth-century speakers; the past can never speak for itself. The present takes over this function, for it has tamed the Middle Ages.

The usual way to quantify flood damage is by application stage-damage functions. Urban flood incidents in flat areas mostly result in intangible damages like traffic disturbance and inconvenience for pedestrians caused by pools at building entrances, on sidewalks and parking spaces. Stage-damage functions are not well suited to quantify damage for these floods. This paper presents an alternative method to quantify flood damage that uses data from a municipal call centre. The data cover a period of 10 years and contain detailed information on consequences of urban flood incidents. Call data are linked to individual flood incidents and then assigned to specific damage classes. The results are used to draw risk curves for a range of flood incidents of increasing damage severity. Risk curves for aggregated groups of damage classes show that total flood risk related to traffic disturbance is larger than risk of damage to private properties, which in turn is larger than flood risk related to human health. Risk curves for detailed damage classes show how distinctions can be made between flood risks related to many types of occupational use in urban areas. This information can be used to support prioritisation of actions for flood risk reduction. Since call data directly convey how citizens are affected by urban flood incidents, they provide valuable information that complements flood risk analysis based on hydraulic models.

Image design for healthcare instruction must be attuned to the way we learn and the formulation of our abstract knowledge. Images for a manual on how to use a medical device will differ significantly in presentation from images that are intended as guidance on how to improve corporal performance. Images for the former will rely on intentional recollection of life experiences, learned concepts and facts as tools. While not mutually exclusive, images for the latter should be designed to consciously work with procedural memory to improve bodily performance. The images in this article demonstrate this by imaging the relationship between the pelvic floor muscles, clitoris and demarking “Spots” indicated for sexual arousal. Qualitative data suggests that many individuals know little about the interactive relationship between the clitoris, pelvic floor muscles and the female orgasm. Social and educational venues are inadequate, and in some cases misleading. The use of appropriate images conveys meaning very effectively. So whether imaging for a medical condition, procedure (e.g., surgery) or device to enfranchise the patient in their wellness the individual’s experience and proclivity for learning must be considered. If the images are effectively planned and executed, images can play an important role in involving the patients in their wellness. Enfranchising the patient into the process can improve patient feedback therein contributing to advancements in medical procedure and device usage. The sequence of images is guidance based upon a woman’s innate understanding of her body, so that she may move to a higher state of knowledge where her body performs better. Further, if her mind is inspired by the success, then her body could proceed beyond the achieved state repeatedly. The data confirms this performance structure. Women who score high for pelvic floor strength and coordination report high sexual functioning and genital perception.

Social media has evolved as an inseparable entity in everybody's life. People make use of social media like Face book, twitter, etc. to express their feelings. That's the reason organizations make use of social media information to infer the behavior of its users. The recent ChennaiRains2015 followed by Chennai flood show the reachability of social media as most of the people have utilized it to convey their status and requirements. Many people have utilized the same social media to express their willingness for providing help (food, shelter, evacuation and medical) to the flood victims. Connecting such people to the needy in a timely manner can make the disaster management process more efficient. In this paper, the authors highlight, (1) the design of Apache Storm based real time analytics of twitter data for extracting location and status of flood affected areas and (2) the development of an optimized map connecting the volunteers (people ready to help flood victims) and the flood victims who have raised their requests via social media.
