This work is part of a joint project funded by the Science and Technology Development Fund (STDF) of the Arab republic of Egypt and the Federal Ministry of Education and Research (BMBF) of the Federal Republic of Germany. Continuation of the use of fossil fuels in electricity production systems causes many problems such as: global warming, other environmental concerns, the depletion of fossil fuels reserves and continuing rise in the price of fuels. One of the most promising paths to solve the energy crisis is utilizing the renewable energy resources. In Egypt, high insolation and more than 90 percent available desert lands are two main factors that encourage the full development of solar power plants for thermal and electrical energy production. With an average temperature of about 40 °C for more than half of the year and average annual sunshine of about 3200 hours, which is close to the theoretical maximum annual sunshine hours, Aswan is one of the hottest and sunniest cities in the world. This climatic condition makes the city an ideal place for implementing solar energy harvesting projects from solar updraft tower. Therefore, a Solar Chimney Power Plant (SCPP) is being installed at Aswan City. The chimney height is 20.0m, its diameter is 1.0m and the collector is a four-sided pyramid, which has a side length of 28.5m. A mathematical model is used to predict its performance. The model shows that the plant can produce a maximum theoretical power of 2 kW. Moreover, a CFD code is used to analyse the temperature and velocity distribution inside the collector, turbine and chimney at different operating conditions. Static calculations, including dead weight and wind forces on the solar updraft chimney and its solar collector, have been performed for the prototype. Mechanical loading and ambient impact on highly used industrial structures such as chimneys and masts cause lifetime-related deteriorations. Structural degradations occur not only from rare extreme loading events, but often as a result of the ensemble of load effects during the life-time of the structure. A Structural Health Monitoring (SHM), framework for continuous monitoring, is implemented on the solar tower. For the ongoing case study, the types of impacts, the development of the strategic sensor positioning concept, examples of the initially obtained results and further prospects are discussed. Additional wind tunnel tests have been performed to investigate the flow situation underneath the solar collector and inside the transition section. The flow situation in and around the SCPP has been simulated by a combination of the wind tunnel flow and a second flow inside the solar tower. Different wind tunnel velocities and volume flow rates have been measured respectively. Particle Image Velocimetry (PIV) measurements give some indication of the flow situation on the inand outside of the solar tower and underneath the collector roof. Numerical simulations have been performed with the ANSYS Fluent to validate the experimental tests.
Lyapunov-based analysis for flight control clearance

This report describes some systematic techniques for finding Lyapunov functions for certain classes of uncertain systems, possibly interesting for use in clearance of flight control laws. We consider three types of uncertain systems, affine, polytopic and LFT systems. All the techniques result in linear matrix inequalities which can be solved using convex optimization for which there exist efficient solvers.
Recovery of Time-Varying Graph Signals via Distributed Algorithms on Regularized Problems

The recovery of missing samples from available noisy measurements is a fundamental problem in signal processing. This process is also sometimes known as graph signal inpainting, reconstruction, forecasting or inference. Many of the existing algorithms do not scale well with the size of the graph and/or they cannot be implemented efficiently in a distributed manner. In this paper, we develop efficient distributed algorithms for the recovery of time-varying graph signals. The a priori assumptions are that the signal is smooth with respect to the graph topology and correlative across time. These assumptions can be incorporated in an optimization formulation of the algorithm via Tikhonov regularization terms. Our formulation is tailored to yield algorithms that can be efficiently implemented in a distributed manner. Two different distributed algorithms, arising from two different formulations, are proposed to solve the optimization problems. The first involves the $\ell _2$-norm, and a distributed least squared recovery algorithm (DLSRA) is proposed that leverages the graph topology and sparsity of the corresponding Hessian matrix. Updates of the Hessian inverse are not required here. The second involves the $\ell _1$-norm and the philosophy of the alternating direction method of multipliers (ADMM) is utilized to develop the algorithm. An inexact Newton method is incorporated into the conventional ADMM to give a distributed ADMM recovery algorithm (DAMRA). The two distributed algorithms require only data exchanges between vertices in localized neighbourhood subgraphs. Experiments on a variety of synthetic and real-world datasets demonstrate that the proposed algorithms are superior to the existing methods in terms of the computational complexity and convergence rate.
Shelf life Study of Freshwater Fishes Using Neem (Azadirachta indica) Extract as a Natural Preservative

Fishes are important food components from ancient time (Noor et al., 2013) and it is highly perishable food. The preservation of fishes is difficult due to its high perishability (Musa et al., 2010; Okoro et al., 2010 and Dewi et al., 2011). Microbial growth and metabolic degradation are major causes of fish spoilage which produce amines, biogenic amines such as putrescine, histamine and cadaverine, organic acids, sulphides, alcohols, aldehydes and ketones with unpleasant and unacceptable off-flavors (Emborg et al., 2005; Dalgaard et al., 2006). A study reported that 30% of landed fishes are spoiled through microbial activity (Amos, 2007). So, there is need of different preservation techniques to International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 8 (2020) Journal homepage: http://www.ijcmas. com
Does 11β-HSD1 Associate with the Development of Visceral Adiposity in Maternal Mg Restricted Wistar/NIN Rat Offspring?

Maternal magnesium restriction irreversibly increased body fat %, specially the visceral adiposity in WNIN rat offspring. We have now investigated whether the increased visceral adiposity was associated with increased adipogenesis and glucocorticoid stress. Female, weanling WNIN rats were fed for 12 weeks, a control (AIN 93G) diet (MgC) or the same with 70% restriction of Mg (MgR) and mated with control males. Some of the pregnant MgR dams were rehabilitated from parturition and their pups weaned on to control diet (MgRP). At weaning half of the pups from MgR dams were shifted to control diet (MgRW) while the other half continued on Mg restriction (MgR). mRNA expression for fatty acid synthase (FAS) and 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) was significantly higher in MgR adipose tissue offspring. However leptin mRNA expression was comparable among different groups. Both the rehabilitation regimes corrected the expression of 11β-HSD1 but not that of FAS. Maternal Mg restriction predisposed the offspring to increased glucocorticoid stress (11β-HSD1) that could underlie the increased body fat %/central adiposity.
Behavioural Signs and Fertility Response Following Spontaneous and Ovsynch Induced Estrus in Sahiwal Cows

The precise detection of estrus is essential to ensure high herd fertility and economic returns from a dairy farm. Generally, majority of farmers use visual observations to detect estrus in cattle. However, Bos indicus do not exhibit pronounced behavioural estrus signs making estrus detection a difficult task. Sahiwal is considered as the best milch breed of indigenous cattle. Like other breeds of Bos indicus cattle, estrus detection is difficult in Sahiwal cows due to less prominent estrus signs and shorter duration of standing estrus (average 10 hours) as compared to Bos taurus cows (Galina and Arthur 1990, Pinheiro et al., 1998). Application of estrus detection aids have been found advantageous, however, their International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 5 (2020) Journal homepage: http://www.ijcmas. com
WP / 17 / 056 Persistence in Incarcerations : Global Comparative Evidence

Purpose The purpose of this study is to assess how incarcerations persist across the world. The focus is on 163 countries for the period 2010 to 2015. Design/methodology/approach The empirical evidence is based on Generalised Method of Moments. In order to increase room for policy implications, the dataset is decomposed into sub-samples based on income levels, religious domination, openness to the sea, regional proximity and legal origins. Findings The following main findings are established. Incarcerations are more persistent in low income, Christian-protestant and Latin American countries while comparative evidence is not feasible on the basis of landlockedness and legal origins owing to unfavorable postestimation diagnostic tests. Justifications for the comparative advantages and relevance of findings to theory-building in public economics are discussed. Practical implications First, income levels matter in the persistence of incarcerations because low income nations vis-à-vis their high income counterparts, have less financial resources with which to prevent and deal with events like terrorism, political instability and violence that lead to incarcerations. Second, the intuition for religious domination builds on the fact that liberal societies can be more associated with incarcerations compared to conservative societies. The main theoretical contribution of this study to the literature is that we have built on empirical validity to provide theoretical justification as to why categorizing countries on the basis of selected fundamental characteristics determine cross-country variations in incarcerations. Such evidence is important for theory-building in public economics. Originality/valueIt is important for policy makers to understand the persistence of incarcerations across nations because resources could be allocated to regions and countries, contingent on the relative importance of future incarceration tendencies.

Effects of removal of extractives on the chemical composition and mechanical properties of wood

Poplar and pine wood were extracted with water, 1% NaOH (wt%) solution, and benzene:ethanol solution (V1 : V2, 2 : 1) to investigate the governing factors and mechanism by which extractives affect wood structure and mechanical properties. The structure, pore distribution, crystal structure, and mechanical properties of samples were analyzed by Fourier transform infrared spectroscopy (FTIR), adsorption of N2 gas, X-ray diffraction (XRD), and mechanical testing, respectively. The results demonstrated that cellulose, hemicellulose, and lignin were degraded to some extent in the course of the dissolution of the extractives. This degradation had a great influence on the structure and quantity of pores. The extraction treatment did not change the crystallization type of the wood, but it increased the crystallinity of the wood, and the length and width of the crystallization area changed. In addition, the mechanical properties of wood were changed when the content of the extractives was reduced.
Multicomponent magnetization in western Dolpo (Tethyan Himalaya, Nepal): tectonic implications

A palaeomagnetic study has been carried out in the Tethyan Himalaya (TH; the northern margin of Greater India). Twentysix palaeomagnetic sites have been sampled in Triassic low-grade metasediments of western Dolpo. Two remanent components have been identified. A pyrrhotite component, characterized by unblocking temperatures of 270–335 jC, yields an in situ mean direction of D= 191.7j, I = 30.9j (k = 29.5, a95 = 5.7j, N= 23 sites). The component fails the fold test at the 99% confidence level (kin situ/kbed = 6.9) and is therefore of postfolding origin. For reason of the low metamorphic grade, this pyrrhotite magnetization is believed to be of thermo-chemical origin. Geochronological data and inclination matching indicate an acquisition age around 35 Ma. The second remanence component has higher unblocking temperatures (>400 jC and up to 500– 580 jC range) and resides in magnetite. A positive fold test and comparison with expected Triassic palaeomagnetic directions suggest a primary origin. The postfolding character of the pyrrhotite component, and its interpreted age of remanence acquisition, implies that the main Himalayan folding is older than 35 Ma in the western Dolpo area. This study also suggests that the second metamorphic event (Neo-Himalayan) was more significant in the Dolpo area than the first (Eo-Himalayan) one. A clockwise rotation of 10–15j is inferred from the pyrrhotite component, which is compatible with oroclinal bending and/ or rotational underthrusting models. This rotation is also supported by the magnetite component, indicating that no rotation of the Tethyan Himalaya relative to India took place before 35 Ma. D 2003 Elsevier B.V. All rights reserved.
Quantitative clay mineralogy as a tool for lithostratigraphy of Neogene Formations in Belgium: a reconnaissance study

Although the main stratigraphic frame of the Neogene in North Belgium is well established still several issues remain. This is in particular the case at the boundaries of lithostratigraphic units and where lateral facies have developed. Not only are more biostratigraphic data needed but also the commonly used geophysical well logging needs a better information on the precise influence of the variable mineralogy in the sediments. In particular glauconite, muscovite and clay mineralogy need a detailed analysis. Such an analysis is carried out on the Antwerp Member of the Berchem Formation, the Diest Formation, the Kasterlee Formation and the Mol Formation with particular emphasis on the boundary intervals between these units. Clay minerals, glauconite, feldspars and muscovite are analyzed. Interstratified glauconite/smectite appears to be common in the low abundant dispersed clay fraction of sand rich in glauconite pellets. Marine units generally consist of detrital smectite-rich assemblages while kaolinite becomes more abundant in units under more continental influence. The presence of Fe-rich vermiculite in a clayey top facies of the Diest Formation indicates the influx of soil material containing weathered glauconite. It is common to find that the basal sediments of a new unit contain the mineralogical heritage of the underlying unit. The clay mineral content has helped to differentiate between units, to locate the boundaries between units and to understand the reworking that occurred at the base of new stratigraphic units. The mineralogical information can also be used to interpret the natural radioactivity and resistivity signals in the borehole logs.
Universality in turbulence: An exactly soluble model

The present note contains the text of lectures discussing the problem of universality in fully developed turbulence. After a brief description of Kolmogorov’s 1941 scaling theory of turbulence and a comparison between the statistical approach to turbulence and field theory, we discuss a simple model of turbulent advection which is exactly soluble but whose exact solution is still difficultto analyze. The model exhibits a restricted universality. Its correlation functions contain terms with universal but anomalous scaling but with non-universal amplitudes typically diverging with the growing size of the system. Strict universality applies only after such terms have been removed leaving renormalized correlators with normal scaling. We expect that the necessity of such an infrared renormalization is a characteristic feature of universality in turbulence.
Mapping of Livelihood Capitals for Technological Interventions in Elephant Foot Yam and Banana Cultivation in Andhra Pradesh

Elephant foot yam is an underground stem tuber and its cultivation is more or less limited to India, Philippines, Indonesia, Sri Lanka and South East Asia. It has high dry matter production capability per unit area than most of the other vegetables. It is a popular tuber crop and is grown as a vegetable in many parts of India, especially South, East and North Eastern states in an area of 30,000 ha with a production of 7.74 lakh tonnes (GoI, International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 8 (2020) Journal homepage: http://www.ijcmas. com
A Processing Advantage for Inalienable Possession: Evidence from English Phrase Plausibility Judgments

Possessive constructions encode a relation between two entities, the possessor and the possessum. For inalienable possession the relation encoded reflects a close, intrinsic connection between the possessor and the possessum (e.g., kinship, part-whole relations) whereas for alienable possession the relation is contingent and extrinsic. The distinction between alienable and inalienable possession, and even between different types of alienable possession, is sometimes overtly marked in the grammar (as in many Oceanic languages) and sometimes only covertly signalled (as in many European languages). In a previous offline study, we found that English attributive possessive phrases containing inherently relational possessums elicited a narrower range of interpretations than those given for phrases containing non-relational possessums (Lichtenberk, Vaid, & Chen, 2011). To the extent that the meaning of inalienable possessive phrases is directly retrievable from the lexical semantics of the relational possessum, we hypothesized that it should be accessed more quickly than the meaning of alienable possessive phrases, which may require additional computation. In the present study we tested this hypothesis using a plausibility judgment task. English adnominal possessive phrases containing relational vs. non-relational possessums each paired with animate or inanimate possessors were presented in the s-genitive form (the N1’s N2). Independently of possessor characteristics, participants were significantly faster at judging plausibility for phrases with relational than those with non-relational possessums. The processing advantage observed for inalienable possession is taken as support for the claim that inalienable possessive relations have a privileged status in the mental lexicon.
Is there an Increase in Fluency over Levels of Proficiency? A Study of English L2 Usage of Japanese University Students

Oral fluency is one of the more difficult variables to track and to measure in L2 speech. This paper reports on an empirical study to identify how fluency in both monologues and dialogues changes over three ranges of proficiency as marked by the TOEIC standardized test. Twenty-seven Japanese students were asked to give a self-introduction monologue, which was then followed by a three-question dialogue. Based on the TOEIC scores of these participants, three groups were formed, with the first group having scores that ranged from 150 to 370, the second from 371 to 570, and the third from 571 to 770. The interactions were videotaped and transcribed with the transcriptions making up the Japanese University Student Fluency Corpus (JUSFC2018), which has 23,539 words. Research questions focused on significant differences among the three groups concerning the variables of monologue speaking time, dialogue speaking time, total speaking time, articulation rate, speaking rate, and the number of words spoken, and mean length runs. Results showed that for the first two proficiency groups monologue speaking time, speaking rates, and the number of words spoken showed significant differences, whereas in comparing the second and third proficiency groups, no significant differences were found. Furthermore, fluency showed a decrease on all variables with the highest proficiency group.
Determination of the best non-linear function to describe the growth of Kajli sheep

The aim of the present study was to determine the best non-linear growth function to describe the growth of Kajli sheep. For this aim, the Brody, von Bertalanffy, Logistic, and Gompertz models were used to describe the sigmoidal relationship between bodyweight and age of the Kajli sheep. The records obtained from the Livestock Experiment Station, Khushab, were collected between 2007 and 2018. The records comprised 9864 age-weight observations (300 for male, 9564 for female, 7392 for single, 2388 for twin, and 84 for triplet lambs), which extended from birth to 12 months old. Candidate non-linear functions were fitted and the curve parameters were estimated by nlsfit (fit non-linear models) function in R statistical package, version 3.6. 1. Goodness of fit criteria that were used to evaluate predictive performances of candidate models were adjusted coefficient of determination (R2adj), Akaike’s information criterion (AIC), Bayesian information criterion (BIC) and root means square error (RMSE). The Brody model was the best non-linear function that described the biological growth pattern of all, male, female, single, twin, and triplet lambs. Differences in curve parameter estimates between male and female suggested a definite pattern of sexual dimorphism. Moreover, a higher estimate of rate of maturity in female lambs reflects their early maturity compared with male Kajli lambs. Similarly, the single-born Kajli animals with highest maturity rate were maturing at an earlier age than twins and triplets. This is the first report on the non-linear pattern of visible changes in bodyweight of Kajli sheep from birth to 12 months old.Key words: age, bodyweight, growth curves, regression, sheep
Effect of Environmental Factors on Biodecolourization of Textile Effluents Using Mutagenised Strains of Pseudomonas and Bacillus Species

Aim: To determine the effects of varying environmental factors on textile effluents biodecolourization ability of mutagenised strains of Bacillus and Pseudomonas species isolated from dye contaminated soil. Study Design: This research study was done using random sampling technique. and Methods: Samples were collected near a textile industry located at industrial Estate Kano. 20 liters of textile effluent were collected randomly at different points of stream where effluents are discharged and 20 g of dye contaminated soil was also collected at different location near the stream. Bacillus cereus , Bacillus firmus , Pseudomonas aeruginosa and Pseudomonas fluorescens were isolated using standard procedure and identified using Microgen biochemical test kit. The Bacillus and Pseudomonas species were modified using Ultra-violet rays at 254 nm and Nitrous acid at different time interval (5, 10, 15, 20, 25 and 30 min). Biodecolorization ability of parent strains and wild strains and effects of varying environmental factors (pH, temperature, agitation, incubation period and co-substrates) was examined. Results: The modified strains (B8 UV 30) had higher textile effluent decolourization potentials of 60.30±0.02% than the parent strain (B8 WS ) which showed 42.26±0.10% biodecolourization activities. The activities of the parent and modified strains were further compared based on effect of environmental factors (temperature, pH, incubation period, agitation and co-substrates). Examination of effects of varying environmental factor showed that the isolates exhibited different activities at different incubation conditions. At temperature of 35ºC, pH7, presence of co-substrate, incubation at 14 day and shaking, the isolates showed higher decolourization activities of 52.92±0.79, 58.82±1.02, 56.42±0.11, 66.16±1.16 and 58.38±0.01 respectively. discharge of textile effluents into the receiving environment.
