An Experiment to Develop Conversion Factors to Standardise Measurements of Airborne AsbestosVarious researchers and agencies recommend different conversion factors for different asbestos exposures. The aim of this study was to develop conversion factors from particles per cm3 (p cm-3) to fibres per cm3 (f cm-3) and from mg m-3 to f cm-3.More than 1000 exposure measurements were available in the Slovenian asbestos-cement factory Salonit Anhovo. Three types of measurement of asbestos concentrations in the air were used: a konimeter measuring p cm-3, a gravimetric method measuring mg m-3 and a membrane filter method measuring f cm-3. Operation-specific conversion factors among these methods were developed. One conversion factor was obtained for asbestos-pipe-dry jobs (4.7) and one for asbestos-sheet-dry jobs (1.6). Only one conversion factor (0.8) was used for asbestos-cement-pipe-wet and asbestos-cement-pipe-dry jobs. For asbestos cement sheets, two conversion factors were obtained (0.3 and 1.2).The development of five different conversion factors made it possible to calculate cumulative exposure to asbestos from historical data and to decrease exposure misclassification.

In this study, gasification performance and importance of hydrogen production using waste of a tea factory were evaluated. A mathematical model was developed for the gasification system, which includes a water gas shift reactor used for hydrogen purification. The gasifier temperature was 877?C for the developed model. The model has been validated against experimental data from an 80 kW t h cylindrical downdraft gasifier, given in the literature for syngas composition for three different air-to-fuel ratios. With the developed model, hydrogen production from tea wastes was achieved to yield a higher level by additionally using a water gas shift reactor. Tea waste (1000 kg) was gasified and after the hydrogen purification process, a total of 4.1 kmol hydrogen was achieved, whereas the amount would be 2.8 kmol gas hydrogen if a normal gasification method were used. The validity of the developed model was verified by comparing the experimental results obtained from the literature with the results of the model under the same conditions. After verification of the developed model, the effect of the moisture content of the biomass and the air/fuel ratio on the composition of the product gas were investigated. These investigations were also confirmed by experimental data. The results show that it is important to convert biomass waste into a clean energy source of hydrogen to minimize its environmental impact.

Marx said that labor makes people, this was one of his fundamental principles. So how are we supposed to understand labor today? What does it mean for us?—Grass Stage,World FactoryThe insistence on “socialism with Chinese characteristics” often sounds quite vacuous, and yet it is a constant reminder of the Chinese resistance to dissolution into capitalism and the continued reaffirmation of one kind of socialist past in the search for another kind of socialist future.—Arif Dirlik, “Back to the Future”

Annotation:

The digital twin model of the factory is the basis for the construction of a digital factory, and the professional system of the factory is complex. The traditional BIM model is not completely consistent with the actual position of the corresponding component, and it is difficult to directly replace the digital twin model. In response to this situation, relying on a certain factory project, the point cloud is used to eliminate the positional deviation between the BIM model and the factory during the construction phase, improve the efficiency and accuracy and reliability of model adjustment and optimization, and , realize the conversion from BIM model to digital twin model. A novel algorithm is developed to quickly detect and evaluate the construction quality of the local structure of the factory, so as to input the initial deformation data of the structure into the corresponding model and feed back to the construction party for improvement. The results show that the digital twin model, which is highly consistent with the actual location of the factory components, not only lays a solid foundation for the construction of a digital factory, but also further deepens the integration and application of BIM and point clouds.

We study lepton flavour-violating interactions which could result in the τ-lepton production in the νμN scattering or in μ → τ conversion on nucleons at high energies. Phenomenological bounds on the strength of [Formula: see text] interactions are extracted from the combined result of the NOMAD and CHORUS experiments on searching for νμ - ντ oscillations. Some of these bounds supersede limits from rare decays. We also propose a "missing energy" type experiment searching for μ → τ conversion on nucleons. The experiment can be performed at a present accelerator or at a future neutrino factory.

In this paper, a micro-fluidic optimized process for the continuous flow synthesis of azo compounds is presented. The continuous flow synthesis of Sudan II azo dye was used as a model reaction for the study. At found optimal azo coupling reaction temperature and pH an investigation of the optimum flow rates of the reactants for the diazotization and azo coupling reactions in Little Things Factory-MS microreactors was performed. A conversion of 98% was achieved in approximately 2.4 minutes and a small library of azo compounds was thus generated under these reaction conditions from couplers with aminated or hydroxylated aromatic systems. The scaled up synthesis of these compounds in PTFE tubing (i.d. 1.5 mm) was also investigated, where good reaction conversions ranging between 66–91% were attained.

Annotation:

Despite a very large variety of improvised firearms, repeatability of certain actions of the manufacturers can be observed, reflecting the purpose to which such weapons are produced (e.g. poaching), and the availability of appropriate technologies. The aim of this article is to make an attempt to systematize improvised firearms on the basis of the expert opinions elaborated at the Weapon Research and Ballistics Department of the Voivodeship Police Headquarters in Kraków (LK KWP) as well as studies carried out on weapons belonging to the collection of the Department of Forensic Medicine (ZMS) in Kraków. Research material included both primitive devices made by using simple methods and without concern for accuracy or aesthetics, as well as fine-tuned pieces with individual design solutions or copies of factory-made weapons. Improvised firearms can generally be divided into conversions and own designs. The conversion most frequently applies to alarm, gas or pneumatic weapons. It consists in removing factory safety mechanisms or, in the case of pneumatic weapons, in introducing technical modifications, which enable to blast off the cartridge and discharge the projectile by means of gas pressure arising during combustion of the propellant. Own designs may contain certain factory elements, most frequently the barrel, however, in most cases, they are manufactured from scratch. Improvised firearms, even those without the original elements, typically use ammunition with projectiles or, in some cases, the so called blank ammunition converted into live ammunition by adding projectiles.

Annotation:

Wastewater from a formaldehyde-urea adhesives factory is characterised by a high organic matter content (COD between 460 and 3900 mg/L mostly due to formaldehyde 220–4000 mg/L) and organic nitrogen (TKN 110–805 mg/L). Besides, a fraction of COD is given by a formaldehyde-urea polymer with a relatively high molecular weight. In a lab-scale (2 L) activated sludge unit, a high formaldehyde removal (higher than 99%) was obtained while the total COD and TKN removal ranged between 70–85 % and 30–50%, respectively. Formaldehyde was used by microorganisms as carbon source and also for the conversion of nitrate to nitrogen gas. The Organic Loading Rate (OLR) was between 0.2 and 1.2 kg–COD/m3·d and the Hydraulic Retention Time (HRT) between 0.5 and 1.4 d. The non degraded TKN and COD, mostly corresponding to the polymeric fraction, was further treated in an ozonation unit, which increased very efficiently the bioavailability of TKN towards nitrification and allowed an additional COD removal. Results from lab-scale reactors were used for designing and operating an industrial scale activated sludge unit, being the efficiency attained at full-scale similar to the laboratory unit.

In Europe, ethanol is blended with gasoline fuel in 5 or 10% volume (E5 or E10). In USA the blend is 15% in volume (E15) and there are also pumps that provide E85. In Brazil, the conventional gasoline is E27 and there are pumps that offer E100, due to the growing market of flex fuel vehicles. Bioethanol production is usually by means of biological conversion of several biomass feedstocks (first generation sugar cane in Brazil, corn in the USA, sugar beet in Europe, or second-generation bagasse of sugarcane or lignocellulosic materials from crop wastes). The environmental sustainability of the bioethanol is usually measured by the global warming potential metric (GWP in CO2eq), 100 years time horizon. Reviewed values could range from 0.31 to 5.55 gCO2eq/LETOH. A biomass-to-ethanol industrial scenario was used to evaluate the impact of methodological choices on CO2eq: conventional versus dynamic Life Cycle Assessment; different impact assessment methods (TRACI, IPCC, ILCD, IMPACT, EDIP, and CML); electricity mix of the geographical region/country for different factory locations; differences in CO2eq factor for CH4 and N2O due to updates in Intergovernmental Panel on Climate Change (IPCC) reports (5 reports so far), different factory operational lifetimes and future improved productivities. Results showed that the electricity mix (factory location) and land use are the factors that have the greatest effect (up to 800% deviation). The use of the CO2 equivalency factors stated in different IPCC reports has the least influence (less than 3%). The consideration of the biogenic emissions (uptake at agricultural stage and release at the fermentation stage) and different allocation methods is also influential, and each can make values vary by 250%.

Conversion coating in metal material was a method to control the corrosion. It applied in parts of car, aircraft, factory installation, and other appliances. There were three types of conversion coating: phosphate conversion coating, chromate conversion coating, and oxalate conversion coating. There were several aspects to consider in controlling the corrosion fully. This research used phosphate because phosphate conversion coating had a low corrosion rate, affordable production cost, and environmentally friendly. This research aimed to find out the corrosion resistance of ST37 carbon steel using phosphate conversion coating in various immersion durations. Therefore, the result was a breakthrough in using phosphate conversion coating for the industries. This research used the weight loss method to calculate the corrosion rate and macro photos to obtain the corrosion form during the test. This research used ST37 carbon steel with 100 mm x 30 mm x 10 mm as the specimen and phosphate with various coating durations (10, 20, and 30 minutes). Each variation had three specimens, so this research had nine specimens in total. This research calculated the daily corrosion rate for seven days using 5% NaCl as the corrosion solution. The average corrosion rate in specimens with 10 minutes duration was 1.9599 mpy, specimens with 20 minutes immersion was 1.7647 mpy, whereas specimens with 30 minutes duration were 1.3287 mpy. Thus, the longer immersion duration created a smaller corrosion rate. Also, the corrosion formed during the test was pitting and uniform corrosion.

By using heavy polycyclic aromatic hydrocarbon from a factory in Northwest China as raw material and 6% Ni/USY as catalyst, a study on hydrogenation process is carried out with a high-pressure hydrocracking assessment device, which mainly focuses on investigating the effect of LHSV, oil hydrogen ratio, temperature and pressure on heavy polycyclic aromatic hydrocarbon. Experimental results show that under the condition that the optimum LHSV is 3.0 h-1 and the ratio of oil to hydrogen is 600, both conversion rate of heavy components and yield of one-membered ring increase at first and then decrease with reaction temperature, with the peak value of conversion rate at 320°C and yield peak at 340°C. Though fluctuates with the increase of pressure, but conversion rate of heavy components shows an overall upward trend. Yield of one-membered ring increases at first and then decreases with pressure, and eventually tends to stabilize. When the temperature is greater than 300°C, the yield slightly fluctuates with pressure and shows an overall increasing trend.

The standard model (SM) of particle physics describes how the Universe works at a fundamental level. Even though this theory has proven to be very successful over the past 50 years, we know it is incomplete. Many theories that go beyond the SM predict the occurrence of certain processes that are forbidden by the SM, such as muon to electron conversion. This paper will briefly review the history of muon to electron conversion and focus on the high-precision experiments currently being proposed, COMET (Coherent Muon to Electron Transition) and Mu2e, and a next-generation experiment, PRISM. The PRISM experiment intends to use a novel type of accelerator called a fixed-field alternating-gradient (FFAG) accelerator. There has recently been renewed interest in FFAGs for the Neutrino Factory and the Muon Collider, and because they have applications in many areas outside of particle physics, such as energy production and cancer therapy. The synergies between these particle physics experiments and other applications will also be discussed.

The article explores some of the connections between science and agribusiness in the history of pig factory farming in Ontario, Canada, between the 1950s and the present. The factory farm model of pig production submits animals to a very artificial way of life, which would not be possible without the inputs of scientific and technological innovations of the 20th century. Topics discussed include the use of antibiotics, swine nutrition, feed conversion (in)efficiency, and pork promotion and consumption. The primary sources utilized are a trade magazine, a census of agriculture, and other government and industry publications. The article sheds light on how notions such as “progress”, “improvement”, “modern” or “efficiency”, frequently used by scientists when referring to results of pig production, are restricted to narrow or internal considerations of the industry that, in turn, can be challenged by broader analysis of aspects (social, economic, environmental) of the food system. Scientists have not just produced scientific knowledge but in some cases have also promoted ideologies about animals and the food system. These ideologies of “progress”, “improvement”, “modern” or “efficiency”, as in the context of pig production in Ontario, only make sense if we understand the particular historical moment in the analysis, which since the 1950s has markedly been one of strong agribusiness interventionism.

An AC-linked large scale wind/photovoltaic (PV)/energy storage (ES) hybrid energy conversion system for grid-connected application was proposed in this paper. Wind energy conversion system (WECS) and PV generation system are the primary power sources of the hybrid system. The ES system, including battery and fuel cell (FC), is used as a backup and a power regulation unit to ensure continuous power supply and to take care of the intermittent nature of wind and photovoltaic resources. Static synchronous compensator (STATCOM) is employed to support the AC-linked bus voltage and improve low voltage ride through (LVRT) capability of the proposed system. An overall power coordinated control strategy is designed to manage real-power and reactive-power flows among the different energy sources, the storage unit, and the STATCOM system in the hybrid system. A simulation case study carried out on Western System Coordinating Council (WSCC) 3-machine 9-bus test system for the large scale hybrid energy conversion system has been developed using the DIgSILENT/Power Factory software platform. The hybrid system performance under different scenarios has been verified by simulation studies using practical load demand profiles and real weather data.

Exploitation of low and medium temperature thermal sources, in particular those based on biomass combustion and on industrial residual heat recovery, has been increasingly investigated in the last decades, accordingly to the growing interest towards reduction in primary energy consumption and environmental issues. Organic Rankine cycle technology allows designing power plants that are less demanding in terms of auxiliaries, safety systems, maintenance and operating costs when compared to conventional water steam power plants. To support the preliminary technical and economic design of this kind of plants in different contexts, a simulation code of part load and off-design operation of an organic Rankine cycle unit for combined heat and power has been developed. In the paper, taking the real situation of a furniture manufacturing factory as a starting point, it is shown how all energy flows occurring all year long inside the combined heat and power plant, can be estimated on the basis of the thermal user duty time profile, the available biomass flow rate and the adopted operation strategy. This information is the basis in order to correctly evaluate the energetic, economic and environmental advantages of the proposed technical solution, with respect to a particular context, as it is shown in the concluding part of the paper.

“Work while it is day; the night cometh wherein no man can work’: John Wesley’s liking for John 9.4 will not surprise a modern student of evangelical history. That there was a Weberian elective affinity between Methodism and diligence has become something of a truism among sociologists examining the cluster of values comprising the Protestant ethic and social historians probing the psychological roots of industrialization in England. Thanks to a famous chapter in E. P. Thompson’s Making of the English Working Class, countless students perceive Methodism primarily as an agency of time-work discipline, internalizing a gospel of work in the pre-industrial labourer and recasting him, by way of the fiery mould of a conversion experience, into the submissive factory worker.

This paper presents the results of nine years of experience in design and operating of full-scale anaerobic-aerobic treatment plants in a fermentation industry producing baker's yeast from sugarbeet molasses. The PAKMAYA Izmit Factory has a large two-staged treatment plant since 1986: anaerobic first stage and aerobic second stage. The anaerobic reactors were constructed as Upflow Anaerobic Sludge Blanket Reactors (UASBR) with internal and external sludge recirculation facilities. Average COD removals remain in the range of 75% in the mesophilic anaerobic stage. Average daily biogas production rates are as high as 20,000 m3/day. This treatment plant is one of the largest in the world in terms of biogas production. Similar systems were constructed later in two other factories of the same company (Cumaova-Bolu, Kemalpasa-Izmir). The biogas conversion yield is about 0.65 m3 per kg COD removed. The energy produced from the biogas used in the boiler houses is about 35% of the total energy requirement of the factory. The effluents from the anaerobic first stage are fed to the subsequent aerobic treatment system by mixing with low strength effluents of the factory. The aerobic second stage was designed and operated as an extended aeration activated sludge system. The COD removals of the aerobic stage are averaging at about 60 to 75%. This paper also discusses the operating problems encountered in the various stages of the treatment system and their solutions during the nine years of full-scale operation in three different treatment plants of PAKMAYA.

Background: Laparoscopic cholecystectomy has become a standard technique for gall bladder surgery of symptomatic cholelithiasis. However, conversion to open cholecystectomy is sometimes necessary. The aim of the present study was to assess the predictive factors that increase the possibility of conversion of laparoscopic cholecystectomy to open cholecystectomy.Methods: A total of 621 laparoscopic cholecystectomies were attempted at AL-Mawanee General Hospital and AL-Sader Teaching Hospital in Basrah, IRAQ from June 2012 till June 2016.Of these,43 had to be converted to open cholecystectomies. Patients assessed according to different factors, including age, sex, acute cholecystitis, adhesions of gallbladder and calot's triangle, obesity, previous abdominal surgery, anatomical variation of gallbladder and Calot's triangle and intraoperative complications (bleeding, bile duct injury, visceral injury).Results: Conversion to open cholecystectomy was performed in 43 patients (6.92%). The significant factors for conversions were adhesions of gallbladder and Calot's triangle(39.53%) followed by acute cholecystitis(34.88%). Rate of conversion in other factors are as the following i.e., isolated male gender (0%), age (0%), previous abdominal surgery (9.3%), obesity (2.33%), anatomical variations of gall bladder and calot's triangle (2.33%), intra operative complications including bleeding (4.65%), bile duct injury (4.65%), visceral injury (2.33%) were insignificant factors for conversion.Conclusions: Adhesions of gallbladder and calot's triangle is the most common predictive factor and cause for conversion from laparoscopic cholecystectomy to open cholecystectomy. Acute cholecystitis found to be the strongest factor for conversion despite its incidence is lower than adhesions of gall bladder and calots triangle. Male gender and age more than fifty years are not direct predictive factors for conversions.

Even though textile industry is not considered an energy intensive sector, it comprises a large number of plants consuming and wasting a significant amount of energy that could be, at least partially, conveniently recovered. The objective of this work is to assess the possibilities and convenience of energy recovery from waste heat of different processes of a dry industrial textile laundry. The various thermal wastes from the processes were identified and characterised, in order to estimate their potential recovery and conversion into electricity. A suitable system layout was conceived, in order to exploit the heat deriving from thermal waste of different machinery in the factory, having distinct temperature levels, to an ORC powerplant, which converts the recovered heat into electricity. The ORC cycle was optimized to maximize the thermoelectric efficiency, comparing different possible working fluids. The best fluid was RC318, from which 92.5 kW power output was achieved, at 9.2% efficiency. The economic analysis revealed, conservatively, a payback period of 7 years for the whole system, which is potentially very interesting. The amount of electricity produced by the waste heat recovery equipment is well matched to the company's electrical needs, resulting in a significant reduction of electricity consumption, greatly reducing the electrical withdrawal from the grid and the related costs. The case study, the proposed solutions and the methodology have general aspects and may be extended to a wide range of cases in the sector of industrial textile laundry.

The design of a biphenyl chemical plant from benzene with a capacity of 10,000 tons/year will be built in Tuban, East Java with a land area of 10,010 m2. The raw material in the form of Benzene is obtained from Trans-Pacific Petrochemical Indotama (TPPI), Tuban. The factory is designed to operate continuously for 330 days, 24 hours per day, and requires 214 employees. Biphenyl preparation begins with reacting benzene (2,807.74 kg/hour) in a Pipe Flow Reactor (R-01) at a reactor temperature of 377 oC and a pressure of 2 atm. This reaction takes place with a conversion of 90% and is endothermic so that a Hitech heater is used to maintain the operating temperature. The products that come out of the reactor are biphenyl and hydrogen. It is then cooled and condensed in a Partial Condenser (CD-01) to a temperature of 151 oC. Then enter into Separator-02 (SP-02) to separate hydrogen from a mixture of benzene, toluene and biphenyl. Hydrogen in the gas phase as a result of the separtor. The bottom product in the form of benzene, toluene and biphenyl in the liquid phase is pumped and put into a distillation tower (MD-01) to purify the product with the bottom product in the form of biphenyl with a purity of 99.3%. The result of the distillation tower is benzene and its impurities are recycled as feed into the reactor with a temperature of 83 oC and a pressure of 1 atm. This factory requires Fixed Capital (FC) Rp. 34,341,856,338,- + US$ 4,195,836, Working Capital (WC) (Rp. 127,536,505,173,- + US$ 170,019), Manufacturing Cost (MC) (Rp. 254,092,040,390,- + US$ 816,090), and General Expenses (GE) (Rp. 33,990,417,539,- + US$ 81,609). Economic analysis shows the value of ROI before tax is 50.38 % and the value of ROI after tax is 32.75%. POT before tax is 1.65 years and POT after tax is 2.34 years. The BEP value is 43.11% and the SDP value is 23.75%. The interest rate in DCF for 10 years is 19% on average. Thus, from a technical and economic point of view, a biphenyl plant from benzene with a capacity of 10,000 tons/year is worthy of consideration.

The two freshwater fishes, the catfish Pangasius pangasius (Hamilton, 1822) and the catla fish Catla catla (Hamilton, 1822)were experimented in small culture ponds for growth response and feed conversion ratio during the study period from October 2018 to January 2019. The Pangasius pangasius fish growth rates of test and control ponds were almost equal. The control growth rates of Catla catla fish were higher than the test pond. Among these fishes, the fish Catla catla was the soft bottom habitat and they preferred mud bottom sediments. Among them, the growth rates of fish Catla catla was less than other species. The FCR values of the test ponds are 12.7 of Pangasius pangasius fish and 21.5 of Catla catla fish. The FCR values of the control ponds are 14.9 of Pangasius pangasius fish and 23.8 of Catla catla fish. In the present study, the results of FCR values are very useful for BR Sludge from Distillery Spent Wash. The feeding ratio (FCR) of test ponds is less than control ponds that is very good useful for these culture fishes.

Objective Minimally invasive approaches to lobectomy are increasing. Rates of conversion to thoracotomy are well reported but risk factors are poorly understood. This study aimed to determine the impact of surgical modality (video-assisted thoracoscopic surgery [VATS] and robotic) on conversion as well as to identify other risk factors for conversion. Methods The National Cancer Database (NCDB) was used to identify patients who underwent minimally invasive lobectomy between 2010 and 2015. Patient characteristics were compared between VATS and robotic approaches using chi-squared tests and t-tests. Logistic regression models were used to control for covariates and identify factors associated with all minimally invasive conversion, VATS conversion, and robotic conversion. Propensity score matching was used to compare conversion rates of VATS and robotic lobectomy. Results The study included 51,723 patients with lung cancer who underwent minimally invasive lobectomy (VATS or robotic). Conversion was identified in 7,109 (7.3%) operations. The odds of VATS conversions were nearly twice that of robotic conversions (OR 1.94 P < 0.0001). After controlling for VATS and robotic patient imbalances with propensity score matching, there was a 5% difference in conversion rates (14% vs. 9%, P < 0.0001). Other predictors of minimally invasive conversion included community hospitals, tumor size 4.5 cm or greater, and an increasing Charlson comorbidity index ( P < 0.03 for all). Conclusions VATS is associated with nearly twice the odds of conversion as robotic lobectomy. Identifying specific risk factors for both VATS and robotic conversions may aid in appropriate modality selection and reduction of conversions.

Annotation:

An innovative membrane assisted hybrid bioreactor was used to treat a mixture of two streams produced in a fish canning factory: a highly loaded stream that had previously been treated in an anaerobic contact reactor, and a second stream with a relatively low COD and N concentration. Experiments were carried out during two experimental stages: an aerobic stage, which is focused in the study on the aerobic oxidation of ammonia and COD and a nitrification-denitrification stage in which the study was mainly focused on the removal of nitrogen. Results of the aerobic period pointed out that it was feasible to achieve ammonia and COD removals of around 99% at OLR of 6.5 kg COD/m3·d and NLR of 1.8 kg N-NH4+/m3·d. Specific nitrifying activities of up to 0.78 g N-NH4+/g protein·d and 0.25 g N-NH4+/g VSS·d, were recorded for the attached and suspended biomass, respectively. Around 50-60% of the nitrifying capacity of the reactor was a result of the nitrifying capacity of the biofilm. During the nitrification-denitrification stage 76% of nitrogen removal was attained at an NLR of 0.8 kg N-NH4+/m3·d. The biofilm nitrifying activity was not affected by the operating conditions of the system, as a result of the preferential consumption of COD by suspended biomass in the reactor. Thus, the combination of a hybrid system, with both suspended and attached biomass, and an ultrafiltration membrane module might be an alternative for treating wastewaters in compact biological systems. The intrinsic characteristics of the system made it feasible to operate at high OLR without problems related with the settling properties of the sludge or the drop in the nitrogen conversion. There were no solids in the effluent as a result of the use of the membrane filtration module.

This paper presents a high-temperature probe suitable for operating in harsh industrial applications as a reliable alternative to low-lifespan conventional solutions, such as thermocouples. The temperature sensing element is a Schottky diode fabricated on 4H-SiC wafers, with Ni as the Schottky metal, which allows operation at temperatures up to 400 °C, with sensitivities over 2 mV/°C and excellent linearity (R2 > 99.99%). The temperature probe also includes dedicated circuitry for signal acquisition and conversion to the 4 mA–20 mA industrial standard output signal. This read-out circuit can be calibrated for linear response over a tunable temperature detection range. The entire system is designed for full electrical and mechanical compatibility with existing conventional probe casings, allowing for seamless implementation in a factory’s sensor network. Such sensors are tested alongside standard thermocouples, with matching temperature monitoring results, over several months, in real working conditions (a cement factory), up to 400 °C.

This aims of this research to examine the effect of feed formula with different protein levels on optimal growth cobia. This research method used a completely randomized design (CRD) with three treatments and three replications. The treatment in this study were different protein level commercial feed (as control/46%), and formula feed (protein P1 46% and P2 protein 48%). The parameters tested included absolute weight, daily growth rate, feed conversion ratio, protein retention, and survival rate. The data obtained were analyzed by analysis of variance and continued with the duncan test with a 95% confidence interval. The results showed that the growth of absolute weight and daily growth rates generated from each treatment were significantly different (p <0.05), K (80.30 ± 11.20c g and 1.78 ± 0.25c g/day), P1 (21.87 ± 1.95a g and 0.49 ± 0.05a g/day), P2 (37.43 ± 3.29b g and 0.83 ± 0.07b g/day).
