A NEW ALGORITHM FOR GENERATING A RANDOM PACKING OF ELLIPSOIDAL INCLUSIONS TO CONSTRUCT COMPOSITE MICROSTRUCTURE

The subject of the work is a microstructure of a composite which consists of a continuum matrix and a set of isolated particles homogeneously distributed inside the matrix. It is assumed that the reinforcing particles have ellipsoidal shapes, while distribution and orientation are random. The main point of the work is a new computationally-efficient algorithm to generate microstructure of such a composite. In the algorithm the existing “concurrent” method based on an overlap elimination is extended to ellipsoidal shapes of the particles. It begins with randomly distributed and randomly oriented ellipsoidal particles which can overlap each other. During the performance of the algorithm intersections between particles are allowed and at each step the volumes of intersections are minimized by moving the particles. The movement is defined for each pair of particles based on the volume of the intersection: if two particles are overlapped, then the reference point inside the intersection is chosen and then two particles are moved in such a way that the reference point becomes the tangent point for both particles. To define the relative configuration of two particles (separate, tangent or overlapping) and to choose reference point inside the intersection volume the technique based on formulating the problem in four dimensions and then analyzing the roots of the characteristic equation are applied. The algorithm is able to generate close packed microstructures containing arbitrary ellipsoids including prolate and oblate ellipsoids with high aspect ratios (more than 10). The generated packings have a uniform distribution of orientations.
TOXICITY EFFECT OF CYMBOPOGON CITRATUS (LEMON GRASS) POWDER AND METHANOL EXTRACT AGAINST RUST-RED FLOUR BEETLE, TRIBOLIUM CASTANEUM (HERBST) (COLEOPTERA: TENEBRIONIDAE)

: Insect pests have mainly been controlled with synthetic insecticides in the last fifty years and the protection of stored grains from insect damage is currently dependent on synthetic pesticides. Botanicals are a promising source of pest control compounds. The plant kingdom can be a rich source of a variety of chemicals with the potential for development as successful pest control agents. There is, therefore, an urgent need to develop environment friendly alternatives with the potentials to replace the highly toxic chemicals. Hence in the present investigation the toxicity potential of lemon grass ( Cymbopogon citratus ) was evaluated against adult Rust-Red Flour Beetle, Tribolium castaneum . The Lemon grass ( C. citratus ) leaves were collected from Kodaikanal hill regions and were shade dried for 7 days, pulverized and sieved using 0.5 mm mesh size to obtain fine powders. About 500 g of the powder were dissolved in 1000 mL of 90 % methanol to produce the extract. The powder and extract were used for the bioassay. The powder was tested at 1.0, 1.5, 2.0 and 2.5 g/10 g cow pea grains respectively. The toxic potential of the extract of concentration of 1.0, 1.5, 2.0, and 2.5 mg/mL were evaluated using the filter paper method. The experiment was setup on a completely randomized design using three replicates per treatment. The results indicated significant difference in mean percentage mortality after 24, 48, 72, and 96 h exposure with the powder compared with the control. Significantly higher to 100 % adult mortality was also observed in the extract after 24, 48, 72, and 96 h exposure compared with the control. The LC50 value of the extract was 0.75 mg/20 mL of methanol with an LT50 of 71.10 h. The methanol extract of C. citratus showed the highest mortality compared to the powder which was less toxic. The study showed that C. citratus products are promising insecticides and can be used effectively in the management of Tribolium castaneum in storage of grains and pluses. attributed to difference in pest species, concentration of the treatment, methodology of research, commodity variations, laboratory and environmental differences.
Advanced diagnosis of Alzheimer’s disease by automatically obtaining the best coronal slices for multi-classification recognition

The goal of this contribution is to find out a set of Y slices (coronal slices) from MRIs of patients with Alzheimer’s Disease (AD), Mild Cognitive Impairment (MCI), and Normal images, that provides the maximum accuracy in a multiclass classification system. Images are preprocessed and 2D wavelet coefficients are extracted to form a feature matrix. Using a feature selection algorithm called mRMR, the best features from the matrix are extracted; then, the dimension of the feature vectors is reduced using PCA and finally, it is used to train an SVM to perform multi-class classification. In order to find the best combinations of coronal slices, a multi-objective genetic optimization methodology based on NSGA-II is used and a set of different solutions are extracted from the Pareto front. More relevant solutions are selected using more flexible criteria than that of the Pareto front, and examine what slices and accuracies are achieved. The multi-classification accuracies obtained by the proposed method are 94.2% (the individual of the Pareto front with the highest accuracy) or 91.9% (using the best 13 slices according to their frequency of presence in the Pareto front). It is important to note that not only a good accuracy is obtained in the classification, but also new knowledge about the most relevant coronal slices to distinguish the four MRI classes (AD, Normal, MCI, LMCI).
CD8 T-Cell Induction during Primary Simian Immunodeﬁciency Virus Infection in Cynomolgus Macaques Correlates with Low CD4 (cid:1) T-Cell Activation and High Viral Load (cid:1)

The early immune response fails to prevent the establishment of chronic human immunodeﬁciency virus (HIV) infection but may inﬂuence viremia during primary infection, thereby possibly affecting long-term disease progression. CD25 (cid:1) FoxP3 (cid:1) regulatory T cells may contribute to HIV/simian immunodeﬁciency virus (SIV) pathogenesis by suppressing efﬁcient antiviral responses during primary infection, favoring high levels of viral replication and the establishment of chronic infection. In contrast, they may decrease immune activation during chronic infection. CD4 (cid:1) regulatory T cells have been studied in the most detail, but CD8 (cid:1) CD25 (cid:1) FoxP3 (cid:1) T cells also have regulatory properties. We monitored the dynamics of CD25 (cid:1) FoxP3 (cid:1) T cells during primary and chronic SIVmac251 infection in cynomolgus macaques. The number of peripheral CD4 (cid:1) CD25 (cid:1) FoxP3 (cid:1) T cells paralleled that of memory CD4 Wallac, Turku, Finland). Results were expressed as net mean counts per minute (cpm) by subtracting the mean cpm of the negative control triplicate wells from the mean cpm of antigen- or mitogen-activated triplicate wells. Statistical analysis. We used nonparametric Spearman’s rank correlation tests to investigate the relationship between different T-cell populations and viral load, immune activation, or proliferative response. The Mann-Whitney test was used to compare the viral loads of different groups of macaques during chronic infection. In some cases, we used the area under the curve for analysis of the amplitude of variation of a given parameter throughout primary infection. Statistical analyses were carried out with Statview software (SAS Institute, Inc., Cary, NC).
I NTENSITY OF C HILDREN ' S S OCCER T RAINING AND ITS R ELATIONSHIP WITH D AILY P HYSICAL A CTIVITY R ECOMMENDATIONS

Background: The Covid-19 pandemic several consequences such as the absence of regular physical activity, promoting an increase of weight in children et 2020). Regular exercise practice promotes well known benefits for children (Krustrup et al., 2010). So, it is necessary to evaluate whether children who practice soccer reach the minimum intensities as a way to combat child sedentary lifestyle. Objectives: To compare the intensity of different types of soccer training and compare the training intensity of two teams in the same step and finally determine whether football training can reach the RAF values for children. Methods: 21 athletes born in the 2010 year (10.4 ± 0.1 years; IMC (A) – 18.7 ± 0.5, (B) 42.6 (4.1)) belonging to two different teams (main and secondary) wore the ActiGraph w GT3X+ BT accelerometer during four training sessions (tactical (TT) and simulated game (SG)). The data were analyzed in epoch of 5s and the cut off values were applied according to Crouter (2015). Results: Comparing the two teams, in TT there were differences for all intensities (p < 0.05), where the main team achieve higher intensities. In SG, the intensities were more similar. Between training types, the secondary team applies more intensity in SG, spending more time in vigorous intensity (p=0.002). On average, the main team reached about 80% of the RAF, while the secondary team about 60%. Principal Component Analysis showed that the individual intensity applied in one type of training is consistent among trainings, and that children with higher IMC tend to spend more time in light intensity. Conclusions: Football stimulates mostly moderate intensities in the training context and allows athletes to reach about 70% of the RAF. These results show that soccer seems to be a good option as a promotion of physical activity and healthy lifestyles for children.
Rift Valley Fever Virus NSs mRNA Is Transcribed from an Incoming Anti-Viral-Sense S RNA Segment propagated in Vero E6 cells using anti-RVFV mouse

Analysis of puriﬁed Rift Valley fever virus (RVFV) particles demonstrated the presence of three negative- sense RNA genomes, plus three anti-viral-sense RNA segments. The virion-associated anti-viral-sense S segment served as a template for the synthesis of NSs mRNA immediately after infection. NSs protein synthesis also occurred early in infection, suggesting that NSs protein produced early in infection probably has biolog-ically signiﬁcant roles in virus replication and/or survival in the host. Translation inhibitor treatment of mammalian cells infected with viruses belonging to the Bunyaviridae family generally inhibits viral mRNA synthesis. However, RVFV NSs mRNA synthesis, but not N mRNA synthesis, was resistant to puromycin treatment during primary transcription, pointing to the uniqueness of RVFV NSs mRNA synthesis. Viruses belonging to the Bunyaviridae family carry three single-stranded RNAs, designated L, M, and S. Viral RNA synthesis occurs in the cytoplasm, and the host mRNA-derived cap structure is used as a primer for viral mRNA synthesis (16). Host protein synthesis is essential for viral RNA replication (2, 5, 6, 15, 18) and is also important for viral mRNA synthesis in mammalian cells; viral mRNA elongation, but not initiation, is suppressed in the presence of protein synthesis inhibitors (2, 15, 18). How the host protein synthesis machinery facilitates viral mRNA elongation is unknown; it has been suggested that ribosome binding to nascent
THE LEVEL OF MYELOPEROXIDASE (MPO) AND ANTI- PROTEINASE 3 IN PATIENTS WITH ENTAMOEBA HISTOLYTICA

of 200 suspected patient there was120 infected with the parasite diagnosed by the direct examination method, a blood sample was taken from each one, as well as (60) healthy controls were involved. The study included the measurement of Anti-neutrophil cytoplasmic antibodies c-ANCA (Anti PR3) and anti- myeloperoxidase p-ANCA (MPO) levels by Enzyme linked immuno sorbent assay (ELISA). The results indicated: The prevalence of Entamoeba histolytica by using microscopic examination was 145 (72.5%) in comparison to 120(82.75%) by using Triage (Micro parasite panel test). The level of Myeloperoxidase (MPO) and Anti- proteinase- 3increased significantly (P<0.05) in sera patients in comparison to healthy control, but there is no-significant (P>0.05) differences between the gender in both groups.
The the The Importance of Tax Knowledge for Tax Compliance: A Study on the Tax Literacy of Vocational Business Students

Tax avoidance and tax evasion are frequently discussed topics on both a national and European level. Education can play an important role in fostering tax compliance. This is especially the case in vocational business education, where students are equipped with the knowledge to found a company, and tax-related issues are of importance. As a part of a sound economic literacy, tax literacy comprises knowledge as well as other dimensions, such as attitudes. The focus of this paper is on general tax knowledge and on tax compliance attitudes. Consequently, the main goals are to present the descriptive results on tax knowledge and on attitudes of the students from business colleges in Austria, and to analyze the relationships between knowledge and tax compliance attitudes. As such, a mixed methods approach that integrates an interview study (n = 22), as well as a questionnaire study (n = 688) was applied among the students from the fourth grade of business colleges in Austria. The results give insight into regular misconceptions in the field of taxes, which serve as an important input for instruction. Additionally, knowledge was found to be positively related to a voluntary tax compliance attitude and nega-tively related to a tax evasion attitude. This indicates that knowledge is an important factor for tax compliance.
ON SURFACES OF CLASS VΠ 0 WITH CURVES, II

Introduction. This paper is a continuation of [14]. A compact complex surface is in class VΠ0 if it is minimal and if its first Betti number bx is equal to one. We know many examples of surfaces of class VII0 (VΠ0 surfaces, for short) with the second Betti number b2 positive [2]-[8], [15]-[18]. They are minimal surfaces with global spherical shells [7]. Any minimal surface with a global spherical shell is a VΠ0 surface diffeomorphic to a blown-up primary Hopf surface and it is obtained as a smooth deformation of certain singular rational surfaces [7], [15], [16], [17]. Some of them have been characterized as VΠ0 surfaces with certain kinds of curves on them [1], [13], [14]. For instance, a hyperbolic (or parabolic) Inoue surface is characterized as a VΠ0 surface with a pair of cycles of rational curves (or a pair of a smooth elliptic curve and a cycle of rational curves). Any VII0 surface with b2 positive which we know so far has a global spherical shell and b2 (possibly singular) rational curves, and a cycle of rational curves (possibly with branches). So it might not be too bold to pose the following conjecture:
Clinical Validation of Neuronal Pentraxin Receptor as a Candidate Biomarker for Alzheimer’s Disease

Alzheimer’s disease (AD) is an age-associated neurodegenerative disease characterized by progressive cognitive decline and loss of independence. Disruption of cerebrospinal fluid (CSF) biomarkers, depressed amyloid and elevated tau, confers an AD-like pathological profile. Novel biomarkers are needed to capture disease onset at earlier stages, categorize patients, and monitor progression. Previously, targeted proteomics has identified CSF neuronal pentraxin receptor (NPTXR) as depressed in AD patients. The aim of this dissertation is to verify CSF NPTXR as an AD biomarker in independent cohorts. NPTXR levels were measured in CSF using enzyme-linked immunosorbent assays in three cohorts with participants of: 1) various dementia severities; 2) normal cognition, mild cognitive impairment and AD monitored over a 24-month period; 3) preclinical and early AD. NPTXR negatively correlated with disease severity and cognitive function and was associated with core AD biomarkers. Future functional and molecular studies are needed to determine NPTXR’s contribution to AD pathology.
R E G I O N AL E C O N O M IC INTEGRATION IN S U B - S A H A R AN AFRICA

Since the attainment of political independence, African leaders have repeatedly expressed their commitment to regional Integration, mainly for political and economie reasons. One result is that Africa now has the largest number of regional integration arrangements in the world. Unfortunately, our historical review of these schemes will provide ample evidence that most of them have remained ineffective or dormant. The issue of regional integration has acquired a new relevance and urgency in Africa of late due to wide-reaching changes globally and nationally. For various reasons, contemporary Africa has been forced to operate m a far more hostile external context than a decade ago. Among these are the demise of the Soviet communist ideology and the opening up of markets in Eastern Europe. African leaders have become deeply concerned that such changes will further dimmish aid and capital flows to Africa. Moreover, the past years have witnessed a decisive move towards the formation of regional trading bloes Europe, the Americas, and East Asia which pose a severe threat to Africa's trading prospects. Africa's Situation has become all the more alarming as its national economies are experiencing a deep and prolonged economie crisis. That is why virtually all African states have been compelled to implement IMF and World Bank-mandated Structural Adjustment Programmes (SAPs) in one form or another. SAPs are intended to tighten up government expenditures in order to reduce the budget and balance-of-payments deficits. Their central demands include eliminadon of subsidies; dismantlmg of pnce controls; 'rationalization' of the state sector through privatization, layoffs, wage cuts and closures; liberalization of the economy, guided by 'market forces' domesticallv and 'comparative advantage' internationally; promotion of commodity exports and foreign Investment; and currency devaluation (Daddieh 1995). By all accounts, African leaders have become more convinced than before that Africa has no choice but to pursue regional Integration if it is to transcend its growmg marginalization in the global economy and lts severe economie crisis. Their renewed commitment to regional Integration was clearly expressed during the June
Exploring facets of trust in older adult decisions to adopt mobile commerce

Mobile commerce currently suffers from low adoption rates even though mobile devices are seemingly everywhere. Retailers have not fully tapped the older adult consumer market, a market framed by two significant attributes. Firstly, older adults are currently the largest segment of the USA population and will be for many years. Secondly, older adults are already known to be a lucrative market for low debt their spending power make them a primary interest to online retailers. While research exists for mobile commerce technology, the older adult age group has not yet been a primary focus of exploration. This quantitative study specifically examined aspects of mobile device usage, privacy, and internet trust factors of mobile commerce adoption among older adults by adapting modern technology acceptance theory as the frame-work for the research. This study determined that older adults have similar levels of interest in mobile commerce technology as compared to younger consumers but approach new technology cautiously, with a deeper consideration of risks and consequences.
SUB-SAHARA AFRICAN JOURNAL OF PSYCHOLOGY AND CONTEMPORARY ISSUES

Cognitive health is one of the most important problems for older people, since cognitive decline can lead to a loss of functional status, thus the need to identify factors affecting this decline. Psychological traits, social support have been implicated in several studies. However, the few studies on personality traits, and prospective changes in cognition with advancing age have been mixed. Based on this, this study investigates the role of personality traits, social support in cognitive functioning of aged person. The study adopted a cross sectional research design. This study was conducted in Adeoyo Maternity Teaching Hospital Yemetu Ibadan. The study population comprised the elderly attending AMTH Yemetu Ibadan. The total number of 208 was used for this study. Structured standardized questionnaire was used to gather data. Both descriptive and inferential statistics was used in the analysis of the data collected in testing the stated hypothesis at 0.05 level of significance. There was significant positive relationship among extraversion ( r (208) = . 18, p <. 01), agreeableness ( r (208) = . 19, p <. 01), conscientiousness ( r (208) = . 24, p <. 01) and openness to experience (r (208) = . 24, p <. 01) and cognitive functioning. However, significant inverse relationship existed between Neuroticism ( r (208)= -. 38, p <. 01) on cognitive functioning. The Big-five personality traits and perceived social support jointly predicted cognitive functioning and accounted for 28% of the change observed in the self-report cognitive functioning (R 2 = 0.28, F (6,202) = 13.05, p <. 01). Neuroticism (β = -.36, t= -5.54, p <.01), conscientiousness (β = .18, t= 2.92, p <.05), opennes s to experience (β = .16, t= 2.55, p <.05) and perceived social support (β = .17, t= 2.68, p <.01) independently and significantly predicted cognitive functioning. This have large implications for strategies to prevent or delay the onset of cognitive impairment.
Predictive Effects of Perceived School Environment, Teacher Efficacy, Internal Locus of Control on Secondary Schools Teacher Burn Out

The purpose of this study is to investigate the effect of perceived school environment, teacher efficacy and locus of control on the teacher burnout among secondary schools teachers. The sample of the study consisted of 261 secondary school teachers randomly drawn from twelve secondary schools in three Local Government Areas in Ondo State, Nigeria. A cross-sectional survey design was used to achieve the research objectives. Four reliable and valid instruments were used to collect data from the participants. The results were calculated using mean, standard deviation and Pearson Product Moment Correlation Coefficient. The result shows that there is relatively high level of burn out among the participants. The correlation coefficients among all the variables were significant with strongest relationship between internal locus of control and teacher burn-out (-.484) (p<0.01). Based on these findings, it is suggested that, training, motivation, incentives/awards and other related mechanisms that can boost the teachers sense of efficacy and as well leading to higher levels of internal locus of control among teachers should be put in place by school administrators and government at all levels.
Journal of Arable Crops and Marketing Boron fertilization improves quality and yield of maize ( Zea mays L.)

Boron deficiency drastically affects the yield and quality of many crops especially maize. The low availability of boron in soils is one of the major causes of poor quality and low yield of maize in Pakistan. A wirehouse experiment was carried out at Department of Crop Physiology, University of Agriculture, Faisalabad to optimize the dose of boron to increase quality and yield of maize. Two recommended local maize hybrids Monsanto-919 and Monsanto-5219 were evaluated in a randomized complete block design with factorial arrangements. The Boron was applied as borax @ 0, 0.3, 0.6, 0.9, 1.2 and 1.5 kg ha¯¹ at tasseling stage. Although both hybrids showed non-significant differences in yield attributes exogenous boron supply @ 0.6 kg boron ha¯¹ increased grain yield by 27% as compared to control treatment in both the hybrids. It increased grain oil, protein and starch contents by 10%, 12% and 16% respectively.
