Relationship between Academic Procrastination and Mathematics Anxiety among Secondary School Students

In this technological age mathematical knowledge are not only needed in scientific and technical fields but increasingly important in business, social sciences and even humanities, one cannot afford to procrastinate in the learning of mathematics. Investigation into the reasons for academic procrastination and the importance of mathematics anxiety in the teaching learning of mathematics makes it necessary to study the relationship between academic procrastination among secondary school students. The participants of the study are 352 secondary school students of Kerala. This is an investigation into the relationship between academic procrastination and mathematics anxiety and it also explores the gender difference in the relationship. The study reveals a significant relationship between academic procrastination and mathematics for total sample and subsamples based on gender.
Experience with the pascal P‐compiler

The paper seeks to document the experience of a small group interested in implementing and using Pascal on a modest but perhaps typical minicomputer. The implementation was achieved by transporting the intermediate code produced by a CDC 7600 version of the Pascal P‐compiler to the minicomputer and producing an assembler and interpreter to execute this code on the mini. Some aspects of the performance of the resulting system are reported.
Congenital and nursing effects on the evolution of Schistosoma mansoni infection in mice.

Modification of the immune response to schistosomal infection in children or offspring born to mother R infected with Schistosoma mansoni has been demonstrated in human and in experimental schistosomiasis. One of the hypothesis to explain this fact could be the transfer of circulating antigens and antibodies from mother to foetus through the placenta or from mother to child by milk. The results of this spontaneous transference are controversial in the literature. In an attempt to investigate these questions, we studied one hundred and twenty offspring (Swiss mice), sixty born to infected-mothers (group A) and sixty born to non-infected mothers (group B). These were percutaneously infected with 50 cercariae/mouse, and divided in six sub-groups (20 mice/sub-group), according to the following schedule: after birth (sub-groups A.I and B.I), 10 days old (sub-groups A.II and B.II) and 21 days old (sub-groups A.III and B.III). After the exposure period, the young mice returned to their own mothers for nursing. Six weeks later, the mice were killed. We obtained the following results: 1) There is transference of antibody to cercariae (CAP), adult worms (SWAP) and egg antigens (SEA) from the infected mothers to the offspring, probably through placenta and milk; 2) Offspring born to infected mothers exhibit much less coagulative hepatic necrosis and show a lower number of eggs in the small intestine and a less intense and predominant exsudative stage of the hepatic granulomas when compared with the exsudative-productive stage of the control groups. The findings suggest that congenital and nursing factors can interfere on the development of the schistosomiasis infection, causing an hyporesponse to the eggs.
An adaptive functional split in 5G networks

The 5G radio access network (RAN) features a partially centralized architecture, in which a subset of the network functions are deployed in a centralized unit. Centralizing these functions reduces operating costs and enables coordination techniques. However, the more functions are centralized, the more capacity is needed on the fronthaul network connecting centralized and distributed units. In addition, the required fronthaul capacity also depends on the instantaneous user traffic, which varies over time. Therefore, in order to optimize its performance, the 5G RAN should be able to dynamically adapt its centralization level to the user traffic. In this paper, we present the design of an adaptive RAN that can switch between two different centralization options at runtime. We provide design objectives and challenges, as well as measurement results from a working implementation.
Efficacy and Safety of Gefitinib in Patients with Advanced Head and Neck Squamous Cell Carcinoma: A Meta-Analysis of Randomized Controlled Trials

Background Trials on assessing the benefits of EGFR inhibitors in head and neck squamous cell carcinoma (HNSCC) patients have gradually been published. Nevertheless, the benefits of gefitinib in advanced HNSCC are still unknown. Methods The Cochrane library, PubMed, and EMBASE databases were systematically searched from the inception dates to 17 July 2017, 18 July 2017, and 19 July 2017, respectively. The keywords “head and neck” and gefitinib were used to retrieve in articles and abstracts. An additional search for recently published randomized trials was performed from July 17, 2017, to April 18, 2018. Then we assessed the risk of bias of the included studies based on the Cochrane “Risk of Bias” tool. Quantitative analysis was carried out to evaluate the overall survival (OS), progression free survival (PFS), overall response rate (ORR), and grade 3-4 adverse effects by Review Manager 5.0. 2 and the quality-of-life was analyzed in the included studies. Results Seven randomized controlled trials and a total number of 1287 patients were involved. There were no significant differences in OS, PFS, or ORR between gefitinib and no gefitinib group (HR 1.07, 95% CI 0.93 to 1.22, and P=0.35; HR 0.84, 95% CI 0.69 to 1.04, and P=0.11; RR 1.04, 95% CI 0.90 to 1.20, and P =0.60, respectively). However, gefitinib alone was equivalent to chemotherapeutics (i.e., methotrexate; methotrexate + fluorouracil) in ORR in patients with recurrent HNSCC, and a trend of improvement in QOL in gefitinib group was showed. Toxicities revealed no differences except for diarrhea and skin toxicity (p=0.0003; p=0.03, respectively). Conclusion For patients with advanced HNSCC, gefitinib cannot prolong the OS and PFS or improve ORR, and odds of skin toxicity and diarrhea increased. However, gefitinib alone is equivalent to methotrexate or methotrexate + fluorouracil and tends to improve QOL for recurrent patients.
Lars Bengtssons green adventure

During his fruitful carrier Lars Bengtsson worked mainly with the white and the blue: snow and lakes. However, during the first decade of the 21st century he had a green period: a green roof adventure. Although he may have been suspecting that other engineering solutions may be more effi­ cient and cost effective in preventing urban flooding than the green roofs can be, he recognized and valued the many diverse benefits green roofs may provide in urban environment. These benefits together would justify the establishment of green roofs. Today we know that besides providing aes­ thetic values green roofs may contribute to:
Clinicopathological Study of Eosinophilic Cholecystitis: Five Year Single Institution Experience.

INTRODUCTION Gallbladder diseases are very common in Northern India, most common of which is Chronic Cholecystitis. Rarely, histopathological diagnosis of Eosinophilic Cholecystitis (EC) is given when transmural cellular infiltrate consists of more than 90% eosinophils. AIM To determine the prevalence and clinicopathological profile of eosinophilic cholecystitis at a tertiary care hospital of New Delhi. MATERIALS AND METHODS This was a retrospective clinicopathological study done on twenty two cases of eosinophilic cholecystitis over a period of five years from January 2011- December 2015. In cases diagnosed histopathologically as eosinophilic cholecystitis, clinical details were obtained from hospital records and slides were retrieved. Various histologic features, pattern of the inflammatory infiltrate and association of EC with other medical diseases, drugs and allergic states were evaluated. RESULTS Out of a total of 1370 cholecystectomy specimens received during five year period, Eosinophilic cholecystitis was diagnosed in 22 (1.6%) of the specimens. Clinically, seven of these patients had a clinical diagnosis of acute cholecystitis. Patient's age ranged from 25-64 years and male to female ratio was 1:2.7. Most common symptom reported was abdominal pain. Most of the cases showed gallstones radiologically (90%) while only two cases showed peripheral eosinophilia (9%). Histologically, mucosal and muscular eosinophilic infiltrate was seen in 72.6% of the cases. No association with drug therapy, allergies or other pre-existing medical conditions was noted. CONCLUSION EC is a relatively uncommon entity in which histopathology remains the main stay of diagnosis. Although the presentation may be similar to general cholecystitis, if a postoperative histopathological diagnosis of EC is made, then the patient must be investigated thoroughly to rule out other associated disease conditions, which may have a worse prognosis than cholecystitis itself.
Suppression of stress-induced voiding in copper interconnects

Studied stress-induced voiding in Cu interconnects in the temperature range below 250/spl deg/C, and found two different voiding modes. One mode occurs inside a via having wide wire above it, and can be suppressed by optimizing the via shape and the via-cleaning process. The other mode occurs under a via having wide wire below it and can be suppressed by increasing the Cu grain size and improving the adhesion of the barrier metal with Cu.
Class vs . Identity : The Effect of Candidates ’ Race on the Inequality-Redistribution Nexus ∗

Despite what the economic theory of democracy predicts, redistribution does not respond always to rising inequality. In this paper we argue that redistribution reacts to changes in inequality, as long as the economy is not overshadowed by non-economic issues during the elections. To this end we estimate the race of candidates competing in all elections for U.S. state legislatures since 1980 and show that when there are few (many) racially differentiated electoral contests, redistribution is (not) sensitive to changes in inequality. That is, candidate heterogeneity crucially affects redistribution by raising the salience of identity-related issues compared to class-related ones.
EXPERIMENTAL VALIDATION OF A MODEL TO ADAPT MEASURED DATA AT A STANDARD WEATHER STATION TO REPRESENT SITE-SPECIFIC AIR TEMPERATURE IN AN URBAN STREET CANYON

Meteorological measurements required for the development of a design scheme that responds to the local environment are generally recorded by the weather service in stations that are assumed to be representative of the surrounding region. However, no account is taken of the changes in conditions caused by urban development, even though differences between meteorological conditions within cities compared with adjacent rural areas (the heat island effect) may be substantial. A new analytical model (CAT) provides data representing realistic site-specific air temperature in a city street based only on data from standard weather stations such as those operated at local airports and descriptors of the two sites. The CAT model has been tested on field data measured in a monitoring program carried out in Adelaide in 2000-2001. After calibrating the model, predicted air temperature correlated well with measured data in all weather conditions over extended periods.
FINITE ELEMENT ANALYSIS OF THE AXIAL CAPACITY OF MICROPILES

Micropiles are being increasingly utilized in many ground improvement applications to increase the bearing capacity and reduce settlement, particularly for underpinning existing foundations. This paper presents a two dimensional numerical analysis of the behaviour of a single micropile installed in soft clay and subjected to compression loading. The behaviour of soil is simulated using the elastic-perfectly plastic stress-strain relationship incorporated with the MohrCoulomb failure criterion. The study also examines the effect of micropile geometrical configurations and interface parameters on the estimated capacity.
Soil microbial metabolism and invertase activity under crop rotation and no-tillage in North China

Soil samples were collected at both jointing and maturing stages of maize and wheat to compare the effects of 4-year no-tillage (NT) and conventional tillage (CT) on seasonal variations of microbial biomass carbon (C), metabolic quotient, and invertase activity in a sandy loam soil in North China. Soil invertase activity significantly increased (P < 0.05) from summer to spring of the next year and then significantly decreased ( P < 0.05) from spring to summer. With a delay of about 3 months, soil microbial biomass C and basal respiration altered in a similar pattern, while microbial metabolic quotient changed on the contrary. Compared with CT, the NT practice significantly increased (P < 0.05) soil organic C content, and tended to result in higher soil microbial biomass C and invertase activity, as well as lower soil microbial metabolic quotient, especially at the jointing stage of maize. Our results indicated that NT might play an important role in the improvement of soil microbial efficiency, especially at the maize seedling season.
Even cycles in graphs

Let G be a 3‐connected simple graph of minimum degree 4 on at least six vertices. The author proves the existence of an even cycle C in G such that G‐V(C) is connected and G‐E(C) is 2‐connected. The result is related to previous results of Jackson, and Thomassen and Toft. Thomassen and Toft proved that G contains an induced cycle C such that both G‐V(C) and G‐E(C) is 2‐connected. G does not in general contain an even cycle such that G‐V(C) is 2‐connected. © 2004 Wiley Periodicals, Inc. J Graph Theory 45: 163–223, 2004
Predictors of Safer Conception Practices Among HIV-Infected Women in Northern Nigeria

Background: Persons living with HIV often face discrimination in safe sex and reproductive choices, especially in lowresource settings. This study assessed fertility desires and intentions, risk perception and correlates of ever use of at least one safer conception method among HIV-infected women attending a tertiary health facility in Kano, Nigeria. Methods: Structured questionnaires were administered to a cross section of 328 of 427 eligible HIV-infected women. Fertility desires and intentions, risk perception and safer conception practice were analyzed. Logistic regression was employed to assess for predictors. Results: Of the 328 respondents, 150 respondents (45.7%) wanted more children. The proportions of respondents aware of their transmission risk during pregnancy, delivery, and breastfeeding were 69.5%, 75.3%, and 78.9%, respectively. Further, 68.9% of respondents were aware of the prospects of bearing HIV-negative children without infecting their partners. About 64.8% of women were aware of at least one safer conception method. Safer conception methods everused by the participants include: antiretroviral therapy (ART) (36.7%), timed unprotected intercourse with (10.9%), and without pre-exposure prophylaxis (PrEP) (17.2%), intravaginal insemination (7.3%) and intrauterine insemination (4.7%). Safer conception practice was predicted by marital status (married versus single, adjusted odds ratio [AOR]=1.50, 95% CI =1.10-3.55), parity (2-4 versus 0, AOR=12.1, 95% CI=3.7-39.8), occupation (civil servants versus traders, AOR=0.37, 95% CI=0.16-0.86), husband’s serostatus (seroconcordant versus serodiscordant) (AOR=1.51, 95% CI=1.13-4.64), couple contraceptive use (users versus non-users) (AOR=1.62, 95% CI=1.16-5.83) and transmission risk perception (high risk versus low/no risk) (AOR=2.14, 95% CI=1.18-3.90). Conclusion: We found high levels of fertility desires and intentions and moderate risk perception among a cohort of HIV-infected women in urban Kano, Nigeria. The use of safer conception practices was not common. Our findings underscore the need for healthcare provider capacity building to enhance safer conception counseling and service delivery.
ADOPTION OF E-LEARNING SYSTEMS IN TANZANIA ’ S UNIVERSITIES : A VALIDATED MULTI-FACTORS INSTRUCTOR ’ S MODEL

Current studies indicate that there is no comprehensive instructor model in e-learning systems’ adoption in universities in Tanzania. This paper addresses this problem by developing an instructor model through adapting DeLone and McLean (2003) information system success model. The developed research model answers the following debatable questions: (1) what are the factors which affect the adoption of e-learning systems’ in universities in Tanzania? (2) what is the model which systematically affect adoption of eLearning systems’ in Tanzania? (3) How can this proposed model be validated? This research study employs quantitative, cross-sectional survey, designed for a total of 86 instructors in eight universities in Tanzania. The data is analysed using the Structural Equation Modelling (SEM) using Analysis of Moment of Structure (AMOS 21 software). The results show that the predictors of adoption of e-learning systems in universities include: (1) Service Quality (SQ), (2) Technical Service Quality (TSQ), (3) Course Quality (CQ), (4) Intention to Use (ITU), (5) E-Learning Actual Use (EAU), and (6) Instructor Satisfaction (IS). These findings will help universities, government, e-learning institutions and other e-learning stakeholders to develop suitable policies and strategies to boost sustainability of e-learning systems, as well as acting as the tool to developers in the course of e-learning systems’ adoption. This valid and reliable model bridges the gap of literatures particular in e-learning systems’ adoption in universities in Tanzania and developing world at large. The novelty of this paper lies on impact of trust, university readiness environmental factors, intention to use and actual use on IS success model based on instructor’s perceptions in Tanzania.

HISTOPATHOLOGICAL AND IMMUNOHISTOCHEMICAL STUDIES ON THE LIVER OF CHRONIC HEPATITIS C VIRUS-INFECTED PATIENTS AND HEPATOCELLULAR CARCINOMA IN SHARKIA GOVERNORATE

In the present study, seventy five cases which has been previously proved to have HCV by PCR and preserved in the Early Cancer Detection Unit (ECDU) archive belonging to the Faculty of Medicine, Zagazig University, Egypt were submitted for this work. Routine Hematoxylin and Eosin (H&E) stain for histopathological and cytopathological studies, histochemical (Collagen and Reticulin) stains, immunohistochemical stains (AFP & CEA) were applied to predict and evaluate the role of HCV in liver cirrhosis and development to HCC. Normal architecture was still preserved in most of the chronic hepatitis cases while it was partially lost in few cases. Hepatocellular carcinomas (HCCs) and all of the cirrhotic cases completely lost their normal architecture. Liver fibrosis was absent in some of chronic HCV cases and it was observed in severely infected cases. On the other hand, the malignant criteria of HCC appeared in three types, well differentiated HCC, moderately differentiated HCC and poorly differentiated HCC. Immunohistochemical investigations played a good role in evaluating malignant changes of the studied cases, particularly AFP, although absence of AFP sometimes does not exclude the diagnosis of HCC, meaning, that HCC may not produce AFP. We noticed also that, CEA staining is somewhat similar to AFP in that, there was a high significant correlation between the different histopathological changes and the intensity of reaction, while no correlation could be proved between the tumor grades of HCC and the intensity of CEA staining.

SENIOR SCHOOL STUDENTS PERCEPTION OF THE USE OF GEOGEBRA INSTRUCTIONAL PACKAGE IN LEARNING LINEAR EQUATIONS IN OGBOMOSO, NIGERIA

This study investigated the perceptions of secondary school students towards the use of GeoGebra instructional package in learning linear equations. The focus was on ease of use and usefulness of GeoGebra instructional package. Other variables investigated includes students’ attitude and behavioural intentions towards the usage of GeoGebra. Four research hypotheses were generated and tested at 0.05 alpha level of significance. The study was a developmental research involving training of a group of senior secondary school one (SS1) students and determining their perceptions about GeoGebra. Questionnaire adapted from technology acceptance model was used to collect data. Cronbachalpha was used to determine the reliability coefficient which yielded 0.92. The data obtained were analysed using Pearson Product Moment Correlation statistics. The study revealed that the relationships between student’s perception towards the ease of use and usefulness of instructional package, ease of use of geogebra instructional package and student’s attitude, and student’s attitude and behavioral intention of student about the use of geogebra instructional package were positively high (β=0.901, 0.811,0.842 &0.871) respectively. Based on the results, it was concluded that the attitude of students towards the use of Geolebra instructional package depend on their perceptions on its usefulness and its ease of use. Finally, it was recommended that GeoGebra package should be integrated into theteaching and learning of mathematics in secondary schools.
EPIZOOTIOLOGICAL STUDIES ON GASTROINTESTINAL HELMINTHS AND ASSOCIATED RISK FACTORS IN THE DAIRY ANIMALS OF INTERNAL DRAINAGE DRY ZONE OF RAJASTHAN , INDIA

The aim of this study was to determine the prevalence and risk factors of gastrointestinal helminthic infections in dairy animals of internal drainage dry zone of Rajasthan, India. A total of 609 fecal samples were examined from September 2016 to August 2017. Out of them, 295 (Buffalo: 111, Cattle:184) were found positive with an overall prevalence of 48.44% for different gastrointestinal helminthic infections. The study revealed strongyles as the most dominant infection (44.99%) followed by Strongyloides sp. (6.90%). Seasonal dynamics revealed a highly significant statistical seasonal variation (p<0.05) with maximum infection in rainy season (60.10%) whereas, a non-significant statistical difference in district wise prevalence was reported with the highest prevalence rate in Nagaur district (54.97%). Multivariate binary logistic regression model revealed positive association of summer (B=0.83) and rainy seasons (B=1.39) when compared to winter season whereas, association was reported positive in Nagaur (B=0.27) and negative in Jhunjhunu (B= 1.42) and Churu (B= 0.15) districts when compared to Sikar district. Similarly, a negative association in crossbred (B= 0.75) and buffaloes (B= 0.53) as compared to native animals was reported in the study. Quantitative analysis presented a mild to moderate gastrointestinal parasitic infection in terms of EPG (eggs per gram of feces) ranged from 100 400 (228.57±42.06) and 100 300 (166.67±33.33) for stongyles and Strongyloides sp . respectively. No fluke infection was reported in the dairy animals of the study area during the study period. Coproculture examination exhibited Haemonchus as the most predominant nematode genus, followed by Oesophagostomum sp. , Strongyloides sp. , Trichostrongylus sp. and Cooperia sp. in the decreasing order of prevalence. The current investigation may be used to formulate effective control strategies against gastrointestinal helminthic infections in the dairy animals of the region.
