In Business, to attain the target, the organizations’ facing major concern in both quality and quantity is Job Morale. Business depends intensely on the proficiency of the production department to ensure that items are fabricated in numbers to meet the demand of the market. Whether the production department is whole responsible for entire cause certainly not, the produced items should meet quality which is in the hand of quality, maintenance, and then logistic, research and development, marketing likewise the entire organization takes responsible. In the event that these representatives do not have the Job Morale to create finished items to fulfill the need, at that point an issue prompting unproductive results is a big challenge. The primary objective of this study is to find out the employee’s perception on organizational climate which includes constraints rules and regulations. This study has been carried out with 110 respondent and proper tools of statistical has applied to drive the expected outcome based on the objective of the study. Conclusions were drawn based on the result and recommendation of our research work.

Full textAbstract:
Hydrogen is regarded as the next-generation energy carriers for the future hydrogen economy.1 Among the hydrogen production technologies, proton exchange membrane (PEM) water electrolyzers is considered the favored approach for the implementation of the global hydrogen energy transformation due to its several benefits including high power density operation, low ohmic losses and differential pressure operation. However, (i) high cost mainly from the high platinum group metals (PGM) loading in the catalysts layers; (ii) low durability due to instability of the catalysts layers and membrane; and (iii) poor safety because of hydrogen crossover of PEM water electrolyzers have jeopardized their widespread commercialization. Currently, a new Department of Energy Consortium (H2NEW) has targeted hydrogen production from electrolysis, especially PEM water electrolysis, for use as a clean, sustainable fuel, which can achieve $2/kg hydrogen production cost by 2025.2 This requires a balance between the performance, durability and scale-up cost of membrane electrode assemblies (MEAs) for PEM water electrolyzers. In this work, we demonstrate the capability to fabricate large scale MEAs by the unique Reactive Spray Deposition Technology (RSDT), that have one order of magnitude lower PGM loadings in the catalyst layer than the state-of-the-art (SOA) designs, and activity and durability performance comparable to the SOA commercial MEAs. RSDT is a flame-based method that combines the catalysts synthesis and electrodes deposition processes into one step and thus substantially reduces the time and cost for their fabrication.3–5 The RSDT fabricated MEA with 680 cm2 geometric area electrodes, and loadings of 0.2 mgPt/cm2 in the cathode and 0.3 mgIr/cm2 in the anode has been tested at current density of 1.8 A cm-2, 50 oC, and 400 psi differential hydrogen pressure. The initial steady-state test for over 250 hours, clearly shows excellent activity and stability. In addition, the RSDT fabricated MEA has integrated dual recombination layers that effectively reduce the hydrogen crossover to below 10 %LFL at all current densities from 0.58 to 1.8 A/cm2.

Full textAbstract:
In metal fabrication industry, assembling department plays the major role since it involves risks in assembling the components. Hence, it is always difficult for the manufacturers to identify the criteria of agile manufacturing in assembling department that effects the assembly of the fabricated metal components. Agile manufacturing is one of the innovative method of manufacturing, which focus on the customer satisfaction and also maintaining the quality and cost of the product. Metal fabrication industries generally struggle to find right criteria for better agile manufacturing process. This study focuses on the selection of suitable criteria for agile manufacturing, which requires an in-depth analysis depending on the influence they possess on the agile manufacturing. The objective of this paper is to analyze and identify the most influencing criteria for the metal manufacturing industry based on the customers’ and industrial expert’s perspective. Here we have selected ten different criteria based on the literatures available on the agile manufacturing. The criteria are segregated and ranked according to the nature and influence they possess on other criteria using decision making trial and evaluation laboratory (DEMATEL) methodology. This study also helps the metal fabrication industry to identify the most influencing criteria to implement on agile manufacturing and to have high efficiency on the production. The results show that the customer satisfaction seems to be the primary criteria that will have more influence in metal fabrication industry.

Since 1987, an intensive Portuguese-Spanish collaboration program has been developed on microstructural characterization of LiNbO3 by nuclear (ion-beam and hyperfine interaction) techniques. The collaboration involves the Department of Applied Physics of the Universidad Autónoma de Madrid, on the Spanish side, and the Center of Nuclear Physics and the Department of Physics of LNETI, on the Portuguese side. The combined effort of the two latter institutions is now channeled through the recently created Center for Materials Characterization and Processing.LiNbO3 is an important material for optoelectronic applications, including light modulation, microwave filters, frequency doublers, and those applications based on the photorefractive effect. Photorefractive applications, still at the laboratory level, include holographic information storage, coherent beam amplification, beam deflectors, and applications relying on the production of phase-conjugated beams by four-wave mixing. LiNb03 is particularly useful for optical information processing, optical interconnects, associative memories, and neural net implementations. These applications involve bulk LiNbO3, but mostly waveguide structures fabricated in LiNbO3 substrates. Recently the development of efficient waveguide lasers on ion-implanted and proton-exchanged waveguides has opened a new field whose final objective is the fabrication of integrated laser modulators and frequency doublers on the same “chip.” The mastering and optimization of all these applications rely on an adequate microstructural characterization of the material with particular reference to both intrinsic and extrinsic point defects. The knowledge and control of this microstructure should permit the fabrication of well-characterized and reproducible devices.

Biochar boosts soil fertility and helps plants to withstand drought. Its production locally has been a challenge and that is why an Indigenous Biochar Production Kiln (IBPK) was conceived, designed and fabricated at the Workshop of the Agricultural Technology Department, Federal Polytechnic, Ile-Oluji, Ondo State, Nigeria. IBK convert biomass to carbon-rich organic material through thermal energy. The IBPK has two drums, the Internal Retort Drum (IRD) and External drum of diameters and heights of 350 mm x 600 mm and 500 mm x 800 mm respectively. The total weight of the IBPK was 82.50 kg. The IRD of 116 kg/m3 volume was loaded with 55 kg biomass from wood waste, covered, and placed inside the external drum. The space between the outer wall of the IRD and the inner wall of the outer drum was 75 mm enough to contain firewood lighted and covered to produce the heat needed for the wood waste inside the IRD to convert it to Biochar. Smoke from the IBK escaped through the chimney attached to the external drum’s lid. The operating time for the carbonization was 182 minutes and the conversion efficiency of the IBPK was 71 %. The average temperature of the IBPK during the conversion was 269 °C. The test carried out on the produced Biochar showed the presence of macro elements that included Nitrogen (2.95%), Phosphorus (21.79%), Potassium (4.95%) and Carbon (70.31%). The fabrication cost was Fifty-Two Thousand, Two Hundred Naira only (₦52,200:00). The IBPK is recommended for farmers to produce Biochar as needed for improved farm yield, and young graduates who want to go into Biochar production as a way out of unemployment.

The World Population Prospects 2019: Highlights, published by the Population Division of the UN Department of Economic and Social Affairs, reports that the world population could reach its peak around the end of the current century, at a level of nearly 11 billion. This increase will need to be accompanied by increases in food production, and that too in a world where arable land is becoming an increasingly scarce resource. To address this problem, a relatively new agricultural practice known as Vertical Indoor Farming (VIF), which relies on height, rather than width, to generate agricultural production has emerged as a form of ‘sustainable cultivation of plants.’ It is important to mention that chlorophyll a and chlorophyll b absorb red light ranging from 600 nm to 700 nm wavelength. Red emission from AlGaInP red LED chip is comprised of rather narrow emission spectra from 625 nm–640 nm. In this review, we elucidate a series of transition metal (Cr3+/Mn4+)/ rare-earth (Eu2+) doped silicate and aluminate phosphors emitting in the red region (600 nm – 700 nm) exhibiting high luminescence efficiency for the fabrication of phosphor-converted red LED, which can be mounted on blue LED chip. Consequently the red LED, which will be fabricated by using these red emitting phosphors mounted on blue LED chip will provide the red light in 600 nm to 700 nm region, which can be absorbed by chlorophyll a and chlorophyll b. Solution synthesis mediated approaches will be discussed for the synthesis of these high efficiency phosphors.

Full textAbstract:
Fuel cell bipolar plates are commonly fabricated from graphite, however the associated machining costs are a major limitation to fuel cell commercialization. A promising alternative approach to bipolar plate manufacturing is injection molding of polymer composites. Injection molding is well-suited for mass production and polymeric materials can significantly reduce the weight of the bipolar plate. In this study, polymer composites based on nylon were injection molded with different weight percentages of conductive filler. Initially, carbon fiber was added to nylon 6,6 at weight percentages ranging from 10 to 50%. Results show that the percolation threshold for carbon fiber in nylon occurs around 25 wt%. Multiwalled carbon nanotubes (MWCNTs) were then added to the direct injection-molded nylon/carbon fiber composites to investigate the synergistic effects of multiple conductive fillers. By introducing carbon nanotubes into the polymer matrix, the nanotubes act as a bridge between the carbon fibers. SEM images show that the MWCNTs fill the void between fibers due to their smaller size and their ease of dispersion. This bridging creates more conductive pathways within the polymer matrix, increasing the electrical conductivity of the composite. Samples with MWCNTs reached conductivities of 64 S/cm, nearing the United States Department of Energy technical target for bipolar plate conductivity (>100 S/cm).

Palm growers in Bangladesh are currently facing problems to extract crude palm oil from FFB. The traditional method of palm oil processing is time-consuming, laborious, hazardous, and inefficient resulting in the production of low-quality oil. Though mechanical processing is costly but produces good quality Crude Palm Oil (CPO) and the oil recovery rate is high. A low-cost mechanical (manually operated) oil palm crusher was designed and febricated in the workshop of the Department of Farm Power and Machinery, Bangladesh Agricultural University, Mymensingh. The crusher was designed by using Auto-Cad software. It was fabricated according to design parameters. It is fabricated by stainless steel (SS) shaft, stainless steel cylinder, mild steel (MS) hopper, (MS) hollow bars, MS pressure case cap & Bearing. It requires a very small rotating force. The cost of the crusher is only BDT 12000, which is within the buying capacity of the farmers of Bangladesh. Crusher was mounted on the table or bench. At first 500 gm fresh palm fruits were taken for experimentation. About 300 gm mesocarp and 200 gm oil palm kernel (nuts) were found from 500 gm oil palm fruits. Heating 300 gm mesocarp about 15 minutes and was weighted 280 gm mesocarp due to moisture loss. About 62 gm crude palm oil, 124 gm oil cake, 88 gm skum were collected from 280 gm mesocarp. The average m.c (wb) of fresh palm fruit was found 20.73%. The crushing capacity of the mesocarp of the crusher was o.84 kg/hr. The rotating speed of the screw was 26 rpm. Crude oil percentage was found 22.14%. The total time to extract 62 gm crude palm oil from 500 gm of fresh fruit was 1hr and 15 minutes. The weight of the crusher is 11 kg which is easy to operate by one man. The overall performance of the crusher was found quite satisfactory and could be useful for smallholder palm growers in Bangladesh.

Sorghum (Sorghum bicolor L.) popularly known as “Jowar”, a cereal grain found in tropical and subtropical climate. India ranks fifth in total sorghum production with 4.7 million tonnes (USDA, 2020). Sorghum is grown in India in an area about 4.82 m ha with production of 4.78 m tonnes and productivity of 989 kg/ ha.In Karnataka, it is grown in 0.94 m ha with a production of 0.98 million tonnes and productivity of 945 kg/ha (INDIASTAT, 2020). A designed and fabricated laboratory test-rig of a pendulum impact tester was used to conduct the experiment in the Department of Farm Machinery and Power Engineering, College of Agricultural Engineering, Raichur. The experiment was conducted to determine the engineering properties of sorghum stalk. The independent variables viz., two types of blades (smooth edge and serrated blade), four levels different stalk diameters (12, 16, 20, 24 mm) and three levels of blade cutting velocity (4.40, 6.30, 7.40 m/s) were selected. Results showed that the maximum cutting energy of 35.47 J was recorded at a blade cutting velocity of 4.40 ms-1 at 24 mm stalk diameter and the least cutting energy of 5.23 J was recorded for 12 mm stalk diameter at blade cutting velocity of 7.40 m s-1 for serrated blade for smooth edge blade and the more cutting energy was recorded of 28.65 J for 24 mm stalk diameter at blade cutting velocity of 4.40 ms-1 and the least cutting energy 3.55 J were recorded for 12 m stalk diameter at 7.40 ms-1 for serrated cutting blade. The maximum cutting force of 1477.92 N was recorded at a blade cutting velocity of 4.40 ms1 at 24 mm stalk diameter. The least cutting force of 435.81 N was recorded for 12 mm stalk diameter at blade cutting velocity of 7.40 m s-1 for smooth edge blade and for serrated cutting blade, the more cutting force was recorded of 1193.75 N for 24 mm stalk diameter at blade cutting velocity of 4.40 ms-1 and the least cutting energy 295.84 N were recorded for 12 m stalk diameter at 7.40 ms-1.

SiC power device technology has over the past years continued to gain massive interest in automotive and industrial applications. The majority of devices is today fabricated on 150 mm diameter substrates while the 200 mm diameter substrates still is at early stage in both development and in terms of mass production. An increase of 50 mm in the wafer diameter corresponds to a 78% larger area and then a corresponding increase of the number of devices per wafer. This change impacts on the productivity of a production line and therefore the cost of the final device can be reduced. Higher production volume and lower cost will lead to a further massive implementation of SiC based power devices in the automotive industry that today is rushing on the path of electrification. At STMicroelectronics we are an early adopter of 200 mm substrates since the first substrate was demonstrated in 2021. Development of 200 mm device quality substrates have progressed well and defect density are today in same range as for 150 mm substrates. The ramp up of production is now made in the new STMicroelectronics plant in Catania while R&D unit in Norrköping Sweden continue to further push the limits of the technology. In this paper, we report the latest progress on STMicroelectronics 200 mm diameter crystals and substrates. We will discuss the most suitable characterization routes available and how we can detect device affecting defects at an early stage. In particular we will start by describing the mechanism that is behind the crystal growth process together with the characterization methods that allow to control the quality of the ingot by monitoring the relevant properties (i.e. bulk defectivity, polytype composition, internal stress). We will then describe the main key parameters to be controlled on the substrate to be sure it is suitable for device making (i.e. mechanical behavior, resistivity, surface roughness, effectiveness of the surface preparation). We will also describe the CVD process that is used to grow on top of the substrate an epitaxial layer with proper resistivity and thickness tailored on the device we need to produce for specific applications. In conclusion we will show some data about the correspondence in between device failure and defectivity on both substrate and epitaxial layer. A comparison of the results collected on both 6” and 8” substrates will be reported to show the excellent job performed in our R&D department in Norrköping to increase the wafer size maintaining the same level of quality. On the other side, our production line in Catania is going to be the first of this kind in Europe with a vertical integration that guarantee process control from the SiC powder to the design and characterization of the final power device.

Full textAbstract:
This chapter looks at two rather recent ways that backstudios have moved the virtual world of moviemaking off the screen. “Immersive Hollywood” occurs when fictional characters interact with real-life actors or spectators. As this occurs in the story, they cross the boundary separating the reel from the real as epitomized by the screen, raising questions about the value of Hollywood escapism. By comparison, “appropriated Hollywood” happens when a state apparatus—the police, the Justice Department, the FBI, the CIA, the White House—fabricates a film production as its cover story for a covert sting operation. Here the analogy of Hollywood and the actions of corrupt or unethical (or at least highly secret) state agents draws out the unsettling equivalence of the film industry’s practices of simulation and those of the national security state.

Full textAbstract:
Extensive research was undertaken over the past 20 years to investigate the suitability of cadmium zinc telluride (CZT) crystals as a material for room-temperature nuclear-radiation detectors. Large-volume CZT crystals, with thicknesses up to 2 cm and large effective areas of roughly 5–10 cm2, are needed to fabricate efficient detectors that meet the working requirements of federal agencies, such as the DOE/NNSA (Department Energy National Nuclear Security Administration), Department of Homeland Security (DHS), and the Department of Defense (DOD). However, because of the imperfect methods for growing crystals, the resulting large-volume crystals most often are not perfect single ones, and contain structural defects such as voids, pipes, impurities from source materials, tellurium inclusions and precipitates, vacancies, and vacancy-impurity complexes generated during the process of their production. Other extended defects that may be present include grain boundaries, micro twins, and walls of dislocations (sub-grain boundaries). Identifying these defects, controlling their occurrence and eliminating them from the bulk CZT material currently are important tasks that will improve the yield of detector-grade crystals from ingots, and ultimately better their performance. In this study, we used a post-growth thermal annealing technique to remove the performance-limiting defects caused by tellurium inclusions and associated impurities in the CZT crystals. We realized a 66% ± 16% reduction in the size of the inclusions, with an overall elimination of 17% ± 2% of them. We believe that our experimental results offer a better understanding of the optimal annealing parameters, and of the dynamic properties of post-growth annealing processes.

A lack of knowledge of how to design products specifically for Additive Manufacturing (AM, also referred to as “3D Printing”) is often viewed as a barrier to industrial adoption of the technology. To advance the AM workforce, the author hosted a 10-week university-wide extracurricular competition that challenged students to design, build, and operate remotely piloted ground and air vehicles made entirely via AM and a standardized electronics kit. The context of the competition was guided by the Department of Defense’s shared vision for forward deployment of AM systems to provide agile on-site part production and reduction of supply chain complexity. The competition vehicles were designed to allow future deployed military or civilian engineers to fabricate remotely-piloted vehicles while in battlefield or austere environmental conditions, such as the site of a natural disaster to search for survivors or to carry out reconnaissance missions. The competition served as unique informal learning environment that engaged over 200 students in the emerging principles of “design for Additive Manufacturing” (DfAM). In this paper, the author presents an overview of the competition structure, and the results of preliminary assessment of the students’ gains in design learning.

Full textAbstract:
Abstract Carbon steel pipelines are used to transport hydrocarbons globally because carbon steel is relatively easier to fabricate, safe for use, raw materials are available and less expensive. Amidst these benefits, carbon steel is susceptible to severe corrosion and other anomalies. Pipeline corrosion is a significant concern in the oil and gas industry. It has caused several minor and catastrophic losses of containment with resultant fatalities, environmental pollutions, asset damage, and production downtimes. The increasing failures of in-service pipelines have led the Department of Petroleum Resources (DPR) to intensify regulatory scrutiny of pipeline integrity assessment and management in Nigeria to ensure strict compliance to the regulatory requirements by the Oil Producing Companies. According to DPR Act (Section 2.5.2.1), all pipelines greater than 6" size diameter must be inspected every five (5) years with intelligent pigs (inline inspection tools) that would provide the accurate condition of the pipeline. However, many pipelines in Nigeria are unpiggable or difficult to inspect with intelligent pigs due to the unavailability of pigging facilities (especially in brownfields), pipelines with short bend radiuses, dual diameters, flow parameters, etcetera. This paper explores case studies involving the use of advanced inline inspection technology to conduct inline inspection of difficult-to-inspect dual-diameter pipelines.
