http://ijaems.com/ Open Access international Journal to publish research paper en-us May 2019 The fourth industrial revolution brings a new paradigm, based on advanced manufacturing and industrial internet. So much has been debated about the knowledge and skills of Operator 4.0. However, the cognitive aspects that are intrinsic to this new paradigm are not considered in these analyses. This work aimed to study the Industry 4.0 under a macro, based on information standardization and technology mapping, and a micro vision focused on cognitive ergonomics. Industry 4.0 attributes pointed to an increasing industry complexity during a technological virtualization process, requiring faster and assertive decisions in the face of a wide range of information. It was found that the Operator 4.0 will oversee the solution of increasingly interdisciplinary problems in a digital environment, requiring denser cognitive efforts and more accurate social-emotional skills, such as communication, motivation, autonomy, perseverance, resilience, collaboration and creativity. The case study pointed out as a highlight the Online Predictive Maintenance, which aims to obtain predictability of failure for each component monitored in machines and equipment. The operating routine linked to this new technology confirms how much mental processes will be required in the face of the Industry 4.0 scenario, since a high flow of information was verified, associated with the rapid decision-making in the use of new technologies. http://ijaems.com/detail/industry-4-0-technology-mapping-and-the-importance-of-cognitive-ergonomics/ Mateus Faraj Marques Rocha, Karina Fernandes de Oliveira, Igor Polezi Munhoz, Alessandra Cristina Santos Akkari http://ijaems.com/upload_images/issue_files/1-IJAEMS-APR-2019-5-Industry.pdf Brooding refers to early periods of growth when chicks require supplementary heat to maintain their normal body temperature. Generally, chicks kept in environmental temperatures outside their comfort zone suffer low growth and high mortality rates. Solar energy has a regular daily and annual cycle, and is unavailable during periods of bad weather. Hence requires special storage and distribution of the energy different from the utilization of conventional energy sources. In this study computer models were developed for simulating internal brooder envelope brooding Temperatures and ammonia gas concentration in ppm. Further, analysis was carried out to determine the influence of trombe wall thickness on the variation of hourly internal brooder temperatures for various months of the year. The trombe wall thickness were set at 100,150, 200, 250 and 300mm and hourly temperatures simulated using Matlab computer program. The wall thickness of 100mm and 150 mm yielded maximum brooding space temperature of 36.50C and 35.30C respectively. The resultant brooder temperatures were above the optimal brooding temperature range of 340C for day one and 21 to 240C for the 28th day of brooding. However, the lowest brooder temperatures attained for 100mm and 150mm wall thickness were 29.50C and 30.80C respectively. The wall thickness of 300mm yielded temperature range of 25.70C to 280C.From this study it is deduced that the wall thickness of 100 and 150mm are suitable for development of a chicks’ brooder. Though, supplementary source of heat will be required to keep the birds comfortable for the first one week of brooding period. The brooder pH was set at 10 and the ammonia concentration simulated for 28 days at brooding floor temperatures of 14.80C, 18.70C, 22.60C and 27.40C.The results were that the ammonia concentration increased exponentially from day one to the 28th day of brooding for all the floor temperatures. The highest emission of ammonia was recorded at the temperature of 14.80C for the first fifteen days; but after the 15th day the temperature of 18.70C recorded the highest emission of ammonia. Conversely, the temperature of 27.40C yielded the lowest ammonia emission. Therefore, it is essential in the design of brooders to have provision for facilitating removal of birds’ droppings to minimize emission of the ammonia gas from the floor of the brooder. http://ijaems.com/detail/development-of-computer-models-for-simulating-the-optimum-design-parameters-of-a-passive-solar-heating-chicken-brooder-system/ Mulindi S.

Smallholder poultry production in Kenya faces the challenge of appropriate energy source for brooding. The study evaluatedby simulation and modellingthe performance of a trombe wall in a small-scale brooder. The brooder system under study consist of brick walls and wooden slated floor. The internal dimensions of the brooder being 2.5 x1.2 x 1.5 m.A dynamic model was used for predicting the brooding conditions based on; ambient temperatures, total solar radiation, ventilation size, thickness and colour of the heat absorption wall. The absorption coefficient for glazed brick is 0.35, absorption factor of black colour is 0.9, and thefraction of incident radiation absorbed is 0.89. Considering a wall thickness of 0.15m, thermal conductivity of 0.8 W/m K, density of bricks -1760 kg/m3, surface thermal resistance of the wall - 0.188 m2K, thermal wall surface area of 3.75 m2 and the pen capacity at 30 chicks per square metre. The experimental model of the brooder was solved using a Maltilabcomputer program with appropriate model equations. A case study of Eldoret town was used, where mean monthly solar radiation is 540Wh/m2/dayto 640Wh/m2/day and daily ambient temperature of 14.20C to 280C.The resultant glazed brooder surface temperatures were 770C to 850C. In view of the appropriate brooding temperatures for day old chicks being 340C while at 28 days of age required temperature range is 21-240C.Consequently, the trombe wall can be used to optimally regulate brooder temperatures. Further, the design expert software was used to establish relationship within solar radiation, trombe wall surface temperatures and the optimal brooder envelope temperatures. The analyses showed a linear relationship amongst solar radiation, trombe wall surface temperatures and the optimal brooding temperatures. The results are appropriate data for designing a brooder for physical and physiological studies of chicks. http://ijaems.com/detail/modeling-the-relationships-between-the-solar-energy-trombe-wall-brooder-system-parameters-and-the-brooding-characteristics-of-indigenous-chicken/ Mulindi S.A., Kanali C., Kituu G., Ondimu S., Mutwiwa U. http://ijaems.com/upload_images/issue_files/3-IJAEMS-MAY-2019-2-Modelingthe.pdf There have been no published data reports up to date regarding the heavy metal concentration on both the green mussels Perna viridis and total coliform level from Manila bay adjacent to Sipac Almacen, Navotas Philippines. Hence, this study aimed to provide a recent status on the concentration of heavy metals (Cd, Cr, Pb, and Hg) in the muscular tissues of P. viridis and coliform level from Manila Bay, Philippines. Specimen samples were collected on February 22, 2019, almost 1000 m away from the coastline, immediately brought to the laboratory, morphologically identified, dissected for muscles, and subjected to heavy metal and coliform testing. Tissue samples of P. viridis and sediment samples from Manila bay were subjected to Flame-AAS (atomic absorption spectrophotometry) method for detecting and quantifying heavy metals such as total cadmium (Cd), total chromium (Cr), and total lead (Pb) while the analysis of total mercury (Hg) were done using the Cold Vapor-AAS method. With reference to a previous study, the sediment and P. viridis from this study obtained a lower total Cd, Cr, and total Pb while total Hg concentration is below the resulting limit. The water sample was subjected to multiple fermentation technique to identify the coliform level which shows a high-level result of 1.6 X 103 that is far from the 3000 value set by DAO 2016-08 for SB water body category. The physicochemical analyses on the bay show no value of ecological concern. P. viridis in Manila Bay did not exhibit any serious deformities http://ijaems.com/detail/assessment-of-heavy-metals-in-philippine-green-mussels-perna-viridis-and-level-of-coliform-on-manila-bay-adjacent-to-the-coastline-of-sipac-almacen-navotas-philippines/ Alma E.

The study utilized descriptive method of research having 100 respondents from different private companies. Respondents are equally divided into female and male. Structured questionnaire was the main instrument of the study during the survey conducted. Most of the respondents interviewed were between 18 to 22 years old. There were 4 variables considered in describing how may bullying evaluated in terms of; injustice, destructive behavior, obstruction to achieve work target and work autonomy. The majority of the male respondents are saying that the bullying inside the workplace was particularly happens when someone’s using abusive language. On the other hand, most of the female respondents are saying that it happens when unreasonable work load is given. The majority of the male respondents are saying that the destructive behavior inside the workplace happens when they are the repeatedly target of superior’s ire while most of the female respondents are saying that it happens when they are the repeatedly target of superior’s ire and if they are threatened to remove from work. The majority of the male and female respondents are saying that the obstruction to achieve work target will prevent if reasonable work is given. The majority of the male and female respondents are saying that the work autonomy happens if the job will be performing with atleast supervision. There is a significant relationship between the age of the respondent and their evaluated experiences in bullying. Significant relationship between the sex of the respondent and their evaluated experiences in bullying. The possible programs & policies for companies to solve the existing bullying in the workplace. http://ijaems.com/detail/workplace-bullying-in-private-companies-in-the-philippines-major-cause-of-employee-burnout/ Kenneth L.

The researchers find this important especially to big construction industries, as it will able to guide them in hiring the best people for the job. The methodology used in this research is a descriptive-survey with questionnaire as the main instrument answered by both the laborers and their supervisors who served as respondents of this study. The study found out that the productivity of the laborers sometimes exceeds standards or expectations which implied that they have advanced knowledge in their work. Further, age and monthly compensation were the two main factors that affected their productivity which was an indication that mature laborers with higher monthly income were more productive employees. http://ijaems.com/detail/factors-affecting-laborers-productivity-in-the-construction-companies/ Phoebe Anne M.

The kiln has a capacity of 2,000 tons/day.Mass and energy balance has been performed for energy auditing. The energy lost from the kiln shell is about 4.3 MW. By using secondary shell on the rotary kiln about 3.5MW could be recovered safely.This energy saving reduces fuel consumption (almost 9%) of the kiln system, and increases the overall system efficiency by approximately 2–3%. http://ijaems.com/detail/energy-audit-and-heat-recovery-on-the-rotary-kiln-of-the-cement-plant-in-ethiopia-a-case-study/ Beniam Getasetegn Emyat http://ijaems.com/upload_images/issue_files/7-IJAEMS-JAN-2019-19-EnergyAudit.pdf Image segmentation is always a fundamental but challenging problem in computer vision. The simplest approach to image segmentation may be clustering of pixels. my works in this paper address the problem of image segmentation under the paradigm of clustering. A robust clustering algorithm is proposed and utilized to do clustering on the L*a*b* color feature space of pixels. Image segmentation is straight forwardly obtained by setting each pixel with its corresponding cluster. We test our segmentation method on fruits images, medical and Mat lab standard images. The experimental results clearly show region of interest object segmentation. http://ijaems.com/detail/multi-color-image-segmentation-using-l-a-b-color-space/ Aden Darge, Dr Rajesh Sharma R, Desta Zerihum, Prof Y K Chung http://ijaems.com/upload_images/issue_files/8-IJAEMS-MAY-2019-10-MultiColor.pdf The utilization of bagasse as a fuel in sugar cane industry is well known. The moisture content of fresh bagassse is relatively high which lowers the total heat available from bagasse and effects its combustion efficiency. Therefore bagassse drying has become a necessity in order to improve its combustion efficiency. In the present work, the use of parabolic trough solar collector to generate the heat steam from working fluid is studied. A working fluid is heated up to 398oC as it circulate through the receiver pipes and return to the heat exchanger. Hence, the working fluid circulate through the pipes so it transfers heat to low temperature, low pressure steam, received from Multi Effect Evaporator outlet to generate high temperature steam. The high temperature steam from heat exchanger move towards hollow shape slat chain conveyor to drying bagasse. Heat requirement, Number of transfer unit and heat capacity ratio were calculated as 238662 KWh, 72372W and 0.5 respectively. Thickness of upper surface of hollow shaped slat chain conveyor made from steel was found as 1cm, through which the moisture reduction ratio as 0.20 was found in the 8min drying of bagasse. http://ijaems.com/detail/solar-energy-utilization-for-bagasse-drying-through-hollow-shape-slat-chain-conveyor/ Amit Kumar, Anurag Singh, Dr. Raj Mani http://ijaems.com/upload_images/issue_files/9-IJAEMS-MAY-2019-11-SolarEnergy.pdf Cigarette and cannabis smoking and drinking local gin are closely associated with people of different age groups. This study focused on the haematological evaluation of the effect of local gin consumption alongside cigarette and cannabis smoking on haematological parameters in residents of Ogba/Egbema/Ndoni Local Government of Rivers State. One hundred and eighty subjects were recruited for this study and the age bracket was between 22 – 65 years. Thirty of the subjects served as the control, thirty other subjects were drinkers of local gin alone, thirty other subjects were smokers of the mainly donchester brand of cigarette and cannabis popularly called “igboo” and the remaining ninety subjects were drinkers of local gin who also smokes cigarette and cannabis. The subjects 4ml of blood was withdrawn into EDTA specimen container for full blood count assay after obtaining consent from the subjects. BC-2800 Auto Haematology Analyzer was used for the assay for FBC while Westergren method was used for erythrocyte Sedimentation Rate (ESR).
