NUMERICAL FLUID DYNAMICAL ANALYSIS OF SOLID OXIDE FUEL

Abstract. The computational modeling plays an important role on the project, the design and the evaluation of the Solid Oxide Fuel Cell (SOFC) performance. However, due to the large quantity of double physical phenomena, this modeling shows great complexity. Besides this interdependence, the validation of these models represents a problem because of the small dimensions of these devices, which make it difficult the obtaining of experimental data. In this work, a stack designed on laboratory has its flow and pressure profiles evaluated tri-dimensionally. Through this method, the momentum equations are solved by finite volume technique using a commercial software. It is considered steady state and isotropy to all physical properties, which are determined on constant temperature. The model validation is performed through its two dimensional versions, based on published literature results. The stack, in this case, has ten cells associated in a serial way. The results indicate some heterogeneity on flow between cells and flow distribution nearly homogeneous along each cell. The pressures increase in a asymptotic way at manifolds.
Study The Storage Quality Of Supplemented Bread With Different Levels Of Anise Powder

This study was conducted to study the storage quality of supplemented bread with different levels of anise powder (5%, 10% and 15%) at room temperature and at the refrigerator. The control and supplemented bread were stored at the room temperature and in the refrigerator at 4 C. The mold has grown after two days at room temperature on the control bread sample, while the mold appeared on the supplemented bread with 5% anise powder after three days and the mold appeared on the supplemented bread with 10% and 15% anise powder after six and eight days of production respectively. The storage results in the refrigerator at 4 C showed that the mold grown on control bread after ten days of production, while the supplemented bread samples with 5% anise powder showed the growth of the mold and appearance of green mold in large quantities after 2 weeks, in contrast the supplemented bread samples with 10% anise powder showed the growth of the white mold in little quantities after three weeks, but the supplemented bread samples with 15% anise powder showed also the growth of white bread mold in very little quantities after 1 month of production. The results of chemical analysis showed that anise contains high protein, fat, carbohydrate ,fiber, moisture and ash content (14.075±0.13, 14.325± 0.02, 38.32±0.03 ,16.53±0.01, 9.88 ±0.05 and 6.87±0.1), respectively, also it contains vitamin B complex ( B1, B2, B5, B6), A and C vitamin, (0.332±0.01, 0.340±0.04, 2.789±0.5, 0.58±0.02, 15.56±0.75 and 19.89±0.12), respectively and minerals Ca, Fe, Mg, P, K, Na and Mn (42.171±0.002, 2.453 ±0.003, 53.432±0.001, 0.385±0.001, 536.312±0.672, 11.155±0.085 and 8.981±0.005), the fats content (total saturated, monounsaturated, polyunsaturated and cholesterol) in anise are (0.578±0.1, 8.985±0.58, 3.071±0.1 and 0.00±0.001), also anise contains essential oil such as transanethole and oleoresins, it is considered the major component in anise oil while oleic acid is considered the major compound in all the oleoresins, so anise has antioxidants properties and can be utilized for protecting fat-containing foods because of volatile oils.
R OTOGRAD : D YNAMIC G RADIENT H OMOGENIZATION FOR M ULTITASK L EARNING

GradNorm (Chen et al., 2018) is a broadly used gradient-based approach for training multitask networks, where different tasks share, and thus compete during learning, for the network parameters. GradNorm eases the fitting of all individual tasks by dynamically equalizing the contribution of each task to the overall gradient magnitude. However, it does not prevent the individual tasks’ gradients from conflicting, i.e., pointing towards opposite directions, and thus resulting in a poor multitask performance. In this work we propose Rotograd, an extension to GradNorm that addresses this problem by dynamically homogenizing not only the gradient magnitudes but also their directions across tasks. For this purpose, Rotograd adds a layer of task-specific rotation matrices that aligns all the task gradients. Importantly, we then analyze Rotograd (and its predecessor) through the lens of game theory, providing theoretical guarantees on the algorithm stability and convergence. Finally, our experiments on several real-world datasets and network architectures show that Rotograd outperforms previous approaches for multitask learning.
Innovative pursuance in the propagation of savings and credit Co-operative societies

In the past few decades many Saving and Credit Co-operative Societies (SACCO) in Kenya thrived due to several innovations including but not limited to lowering of their loans interest rates, and providing members with economical banking services. With the increase in the number of organizations willing to emulate the same products to members for example lending money within shorter periods with minimal interest rates due to easy recoverability of the same for example Safaricom - Fuliza and M-Shwari loans, MCO-OP salary loans, Equitel-loans, KCB Mobiloan services, SACCOS are facing very stiff competition from these institutions and if this trend is unchecked, it might lead to the demise of the Co-operative Societies. Therefore there is urgent need for SACCOS to reinvent themselves in order to remain relevant. This study surveys a few innovative ideas that may be adopted and/ or pursued in order to safeguard against the depletion of SACCOS. Among them is the good response of members towards a higher education loan and savings by products, contemporary skills training loan for produce SACCOS such as Agriculture and manufacturing and members dependants by products. Furtherance to indicate that the adoption of the pursued ideas would lend credence to the uniqueness of SACCOS as being the institutions that develop the welfare of their members since these ideas if properly implemented would generally improve members’ wellbeing .
Comparison of Beef Cattle Grazing Management Practices and their Effects on Runoff Water Quality in Louisiana

Management-intensive grazing (MIG) allows better use of grazed forage crops with short-duration grazing in small paddocks and with this study; the water quality was compared for two grazing management methods. Year-round grazing with MIG and continuous stocking (CS) were compared. Four 0.81-ha plots for two replications of the grazing systems were established. Twenty 0.04 ha (0.1 ac) paddocks, established with power fencing, allowed daily cattle rotation in MIG system. Continuous grazing and MIG used the same stocking rate on each experimental plot (0.81 ha). Each year, two crossbred beef (Bos taurus) heifers (390 kg ±12 kg; 12-14 mo at start) were maintained on each plot yeararound for 3 yr, with additional yearling heifers added to maintain similar forage availability between stocking methods. Common bermudagrass (Cynodon dactylon [L] Pers.) was grazed in summer and annual ryegrass (Lolium multiflorum Lam.) was over-seeded into the sod during October for winter and spring grazing. Forage mass was determined monthly and available forage dry matter (DM) was maintained at approximately 1120 kg DM ha Runoff water samples were collected during 42 rainfall events from May 2001 through March 2004. No significant treatment differences (P > 0.10) were found in most of the water quality parameters. Runoff as a percentage of the 3-yr average annual rainfall of 1869 mm was 34% for MIG and 42% CS. The average flow-weighted concentrations of soluble reactive phosphorus (SRP) varied from 5.08 mg P L (ppm) to 8.22 mg P L 1 (ppm) while the NH4–N ranged from 1.07 mg N L (ppm) in year one to 10.11 mg N L (ppm) for the second year (P < 0.05) for year effect. Total annual average forage production was greater (P < 0.05) in the MIG compared to CS with19,796 kg ha for MIG vs. 16,964 kg ha for CS. Beef production also increased with the MIG system with an annual total beef gain from MIG at 422 kg ha y vs. CS at 330 kg ha yr.
SILICON CARBIDE CERAMIC FOAM PRODUCED BY DIRECT MICROWAVE HEATING

The paper presents results of the research of manufacturing silicon carbide ceramic foam applying the microwave energy as a power source for the heat treatment at very high temperature (up to 1610 oC). On the other hand, aluminosilicate waste (clay recovered from recycled brick from building demolition as well as coal fly ash) as silica suppliers, has been used to replace some materials such as quartz or sand, with very high silica content. The obtained product had a very high compressive strength (up to 58 MPa), but the porosity had lower values than those obtained from the commonly used raw material. The most important characteristic of the ceramic foam obtained by the nonconventional method is the extremely low specific energy consumption (maximum 1.42 kWh / kg) required for sintering the raw material at very high temperature, with at least 50% lower than the values obtained by the conventional methods.

Article history: Received September 26, 2019 Accepted November 13, 2019 Available online March 15, 2021 This study aimed to determine the effect of Nitrobacter bacteria on specific growth rate (SGR), survival rate (SR), and feed convertion ratio (FCR) of African catfish (Clarias gariepinus) in aquaponics systems. The sample used was African catfish with a size of 5-7 cm as many as 720 individuals. The research method used was experimental design in the form of Completely Randomized Design (CRD). This study used 5 types of treatments with 4 repetitions. The P0 and P1 contain of 30 fish in each aquarium; 35 fish in P2; 40 fish in P3; and 45 fish in P4. The control group (P0) were treated without Nitrobacter administration and the other 4 intervention groups were given Nitrobacter 1 ml with a density of 1x10 CFU ml. The main parameters studied were SGR, SR and FCR of African catfish in different aquarium with different stocking densities. This research also studied the growth of water spinach (Ipomoea aquatica) also water quality conditions in aquaponics systems. The administration of Nitrobacter in aquaponics systems gave a significant effect on the SGR, SR, and FCR of catfish. The administration of Nitrobacter in an aquaponics system can give maximum effect if there are 45 fish stocking densities and 1 ml Nitrobacter with a concentration of 1x10 CFU ml.
Ownership Structure and Firm Value of Quoted Consumers Goods Firms in Nigeria

This study examined the ownership structure's effect on the firms' value of quoted manufacturing firms (consumer goods) in Nigeria for 2010-2018. The total numbers of quoted consumer goods firms in the Nigeria stock exchange as of 31st December 2018 were twenty-one (21). A judgmental sampling technique was used to sample nineteen (19) consumer goods firms for the study. The study sought to examine whether ownership structure proxy by managerial Ownership, Institutional Ownership, foreign Ownership, and ownership concentration affect firms' values of quoted consumer goods in Nigeria. Data were collected from secondary sources through the annual reports and accounts of sampled consumer goods firms in Nigeria. The study adopted a panel regression technique as a tool of analysis. The result showed a negative effect of managerial ownership on firm value. While institutional Ownership, foreign Ownership, and Ownership concentration all positively affect the firm value of consumer goods firms in Nigeria. Therefore, the study recommends that the numbers of shares held by management should be reduced to increase the firm value of the listed consumer goods companies in Nigeria.

Sensitivity of olive leaf turgor to air vapour pressure deficit correlates with diurnal maximum stomatal conductance

Effective study and management of crops and forests would benefit greatly from useful plant-based indicators of the biological controls on evapotranspiration, and particularly stomatal conductance (gs). Given the strong influence of gs on bulk leaf water potential and turgor pressure (P), in vivo measurement of P may provide useful information about diurnal or seasonal dynamics of gs. Moderate plant water stress affects the diurnal dynamics of P as leaf-to-air vapour pressure deficit (D) varies, and these dynamics correlate to gs. Here, we explored relative changes in P in response to changes in D under mild drought conditions, and how these changes are linked to stomatal behaviour, and specifically to diurnal maximum gs (gs,max), one of the best indicators of plant water stress. We monitored ecophysiological and environmental variables, as well as a relative proxy for P, during three consecutive seasons in a hedgerow olive orchard where trees were supplied with different irrigation treatments to create well-watered and moderately water-stressed conditions. Our results demonstrated that the sensitivity of P to D correlated well with gs,max reached by the trees within a range in which variations in gs are the main diffusional limitation to photosynthesis. We further showed that this correlation held under a wide range of meteorological conditions and soil water availability. This turgor proxy measurement, which is much easier to measure than gs, can facilitate the use of gs,max as an indicator of plant water stress and evapotranspiration in agriculture and plant science research.

Challenging, Hindering Job Demands and Psychological Well-Being: The Mediating Role of Stress-Related Presenteeism

When individuals are under stress, they cannot fully expend all their energies at work because they are distracted due to stress. This concept is termed stress-related presenteeism. The primary purpose of this research was to analyze the relationship of challenging job demands (i.e., workload) and hindering job demands (i.e., cognitive job demands) with stress-related presenteeism, and the subsequent relationship of stress-related presenteeism with psychological well-being, by using the job-demands resource model and conservation of resource theory. Data (n=211) were collected in two-time waves from bank employees of three major cities of Pakistan. The collected data were analyzed by using bootstrapping mediation analysis. Findings revealed that workload was negatively associated with stress-related presenteeism, whereas cognitive job demands were positively related to stress-related presenteeism. Stress-related presenteeism also mediated the relationships of challenging job demands and hindering job demands with psychological well-being. Implications for managers and recommendations are discussed towards the end of this study.
The U in Crypto Stands for Usable: An Empirical Study of User Experience with Mobile Cryptocurrency Wallets

In a corpus of 45,821 app reviews of the top five mobile cryptocurrency wallets, we identified and qualitatively analyzed 6,859 reviews pertaining to the user experience (UX) with those wallets. Our analysis suggests that both new and experienced users struggle with general and domain-specific UX issues that, aside from frustration and disengagement, might lead to dangerous errors and irreversible monetary losses. We reveal shortcomings of current wallet UX as well as users’ misconceptions, some of which can be traced back to a reliance on their understanding of conventional payment systems. For example, some users believed that transactions were free, reversible, and could be canceled anytime, which is not the case in reality. Correspondingly, these beliefs often resulted in unmet expectations. Based on our findings, we provide recommendations on how to design cryptocurrency wallets that both alleviate the identified issues and counteract some of the misconceptions in order to better support newcomers.

Co-Creation of Micro-Content Types

In a knowledge society knowledge is dynamic, distributed and dependent on social context. The variety of professional communities of practice (CoP) and their individual knowledge needs are a challenge for community information systems for learning and knowledge exchange. Social Micro-Learning is an approach that allows the co-creation of new individualized knowledge artifact types for specific needs of a certain CoP. In this paper we propose a co-creation approach for Social Micro-Learning and evaluate it in workshops with four different CoPs in the professional domain. Our results confirm our assumptions about the diversity of knowledge needs and show that our co-creation process is highly appreciated.
