Biochemical diversity and genetic distance within and between Tiv and Fulani Local chickens of Nigeria

The study was undertaken to investigate biochemical diversity and genetic distance within and between Tiv and Fulani local chicken ecotypes of Nigeria. The experimental birds were randomly sourced from ten locations. The locations (1-5) for the Tiv ecotype were Uikpan, Daudu, Kadarko, Yelwata and Cohor (in Benue and Nasarawa States) while that of the Fulani ecotype were Lafia, Akurba, Adogi, Asakio and Namu (in Nasarawa and Plateau States). At maturity, four (4) male and four (4) female birds were randomly selected from each location per ecotype to give a total of eighty (80) adult birds (40 birds each for Tiv and Fulani ecotype) and used for blood protein characterization study. Blood protein loci, namely haemoglobin, albumen, transferrin and carbonic anhydrase were analyzed using electrophoresis. Data collected from the biochemical analysis were analyzed using popgene version 1.31. The results obtained indicate that, the genetic distance based on identity and distance were significant and generally positive in both the Tiv and the Fulani ecotypes. The F-statistics (Fis ) values were positive in the two ecotypes except at alleles B and C in the Albumen locus of the Tiv ecotype and allele B in the Carbonic Anhydrase locus of the Fulani ecotype. The dendogram showed that the two chicken ecotypes originated from a common ancestry but diverge from one locality to another in each ecotype. The genotypic frequency varied across locations in both ecotypes. Haemoglobin genotypes AA and AB were prevalence in the Tiv (0.875) and the Fulani (0.538) ecotypes, respectively. Genotype AC for albumen was most prevalent in both ecotypes. However, albumin genotype AA and AB was not found in the Tiv and Fulani ecotypes, respectively. In transferrin, genotype BD (0.378) and AA (0.568) was most prevalent in the Tiv and the Fulani ecotypes, respectively. Genotype AC in carbonic anhydrase was prevalenth in both ecotypes while genotype BB only found in the Tiv ecotype. From the findings of this study it was concluded that, the genetic diversity within and between the Tiv and the Fulani chicken ecotypes as observed in this study should be exploited through selection within each ecotype and subsequent crossing between birds from different locations/ecotype to take advantage of heterosis.

Efficacy and Safety in Intramuscular Injection Techniques Using Ultrasonographic Data

Delivered by intramuscular (IM) injections, Long Acting Injections (LAI), offering comparatively long term medicinal effects from several weeks to several months, are gaining much attention. The aim of this article was to indicate a safe and effective IM injection technique based on evidenced data derived from ultrasonographic data. Accurate anatomical knowledge is necessary in order to administer IM injections. It is possible to gain an adequate understanding of injection site anatomical structures by using ultrasound diagnostic devices. In particular, ultrasonography offers real-time diagnostic data allowing for observation of injection site, subcutaneous tissues, fat layers, muscle membrane, muscles and bones. To deliver the drug accurately into the muscle is essential, to achieve maximum drug efficacy and prevent injection site reactions. Therefore, when administering IM injections to the buttocks area, a suitable injection needle between 23G 25 mm to 21G or 22G 38 mm must be chosen depending on physique and drug characteristics. Needles determined as safe and effective through ultrasonographic evidence are needed such as in the case of a deltoid injection site, in which a 23G 25 mm injection needle is used in the absence of notable obesity. Not only the needle type is essential, but also the IM procedure itself. It is important to stretch the skin, inserting the needle at 90 degree angle to ensure depth of needle insertion to the muscle. Until new con-firmed evidence becomes available, it is necessary to increase the understanding of injection site selection methods, needle insertion depth, needle angle, and established IM injection techniques. The application of ultrasound devices in the development of next-generation techniques for IM injection is promising. Importantly, these techniques provide critical information from a risk management perspective.
Implications of Methodology and Study Setting Triangulation in Organisational Behaviour Research

The implications of methodology and study setting triangulation in organisational behaviour (OB) were explored in this study. Triangulation continues to be a subject of interest amongst researchers; especially in OB. This paper identified six implications for OB research; some of which include acceptable methodology as a pre-condition; triangulation as an “outside the window” contrivance; triangulation as a promoter of research findings validity; and thatthe expend of cost and time will be more than compensated for by the resultant acceptability and validity of the research findings. It was concluded that the choice of methods for carrying out OB research has a telling effect on the acceptability and validity of the findings, stressing the need for triangulation. Consequently, it was recommended thatOB research can be enhanced through improved methodological triangulation. This can be achieved with a diligent examination of the current trends in OB research and applying same.
Subjective Well-Being of the Rural Elderly: A Survey on Family of Two Villages of Northwest in Bangladesh

The study attempted to investigate Subjective well-being (SWB) of the rural elderly people of two villages in Bangladesh. To reach at the end of the investigation of the study SWB of 402 respondents (male =238, female =164) was measured by administering Memorial University of Newfoundland Scale of Happiness (MUNSH) developed by Kozma and Stones (1980) through a family survey. The t-test and one-way ANOVA were used as statistical tools to analyze the data through IBM SPSS (Version-20.0). Results of the study revealed that, SWB of the elderly people of those villages is relatively better. The finding is not consistent with the findings of earlier studies of Camfield, Choudhury and Devine (2009); Khan, Jahan, and Haque (2007). Comparisons were also made on the basis of gender and level of education of the respondents. Significant difference of SWB was found between male and female respondents. Happiness of male respondents found significantly higher than that of the female counterpart. This finding is supported by the findings of Van Miah et al. (2010); Pinquart and Sorensen (2001); and Plagnol and Easterlin (2008). Results also revealed that, level of education is a strong predictor of mental well-being of the rural elderly resemble the findings of the study of Diener, et al. (1999); Mahmuda, A. (1998); Pinquart and Sorensen (2000); and Yang (2008b).
Experiments on Rock-Bit Interaction during a Combined Thermo-Mechanical Drilling Method

The development of deep geothermal systems to boost global electricity production relies on finding cost-effective solutions to enhance the drilling performance in hard rock formations. Conventional drilling methods, based on mechanical removal of the rock material, are characterized by high drill bit wear rates and low rates of penetration (ROP) in hard rocks, resulting in high drilling costs, which account for more than 60% of the overall costs for a geothermal project. Therefore, alternative drilling technologies are investigated worldwide with the aim of improving the drilling capabilities and therewith enhancing the exploitation of deep geothermal resources. In this work, a promising drilling method, where conventional rotary drilling is thermally assisted by a flame-jet, is evaluated. Here, the thermal weakening of the rock material, performed by flame-jets, facilitates the subsequent mechanical removal performed by conventional cutters. The flame moves on the rock surface and thermally treats the material by inducing high thermal gradients and high temperatures, therewith reducing the mechanical properties of the rock. This would result in reduced forces on the drill bits, leading to lower bit wear rates and improved rates of penetration and therefore significantly decreasing the drilling costs, especially for deep-drilling projects. In this work, the feasibility of the proposed drilling method is assessed by comparing the rock-bit interaction in sandstone and granite under baseline and thermally treated conditions. Rock abrasivity, tool penetration and cutting forces are investigated to quantify the rockbit interaction in granite and sandstone under baseline conditions and after the thermal treatment. The results highlights the dominant mechanisms regulating the rock removal. The removal performance of the tool in the granite material are found to be greatly enhanced by the thermal treatment both in terms of volume removed from the sample and worn volume at the tool’s tip. On the other hand, the sandstone material, after a thermal treatment, yields significantly lower wearing of the cutting tool. Thus, this results allow to draw important conclusions regarding the achievable drilling performances during the combined thermo-mechanical drilling method towards its application in the field.
A THIRTY KILOPARSEC CHAIN OF “BEADS ON A STRING” STAR FORMATION BETWEEN TWO MERGING EARLY TYPE GALAXIES IN THE CORE OF A STRONG LENSING GALAXY CLUSTER

New Hubble Space Telescope (HST) ultraviolet and optical imaging of the strong-lensing galaxy cluster SDSS J1531+3414 (z = 0.335) reveals two centrally dominant elliptical galaxies participating in an ongoing major merger. The interaction is at least somewhat rich in cool gas, as the merger is associated with a complex network of nineteen massive superclusters of young stars (or small tidal dwarf galaxies) separated by ⇠ 1 kpc in projection from one another, combining to an estimated total star formation rate of ⇠ 5 M yr-1. The resolved young stellar superclusters are threaded by narrow H↵, [O II], and blue excess filaments arranged in a network spanning ⇠ 27 kpc across the two merging galaxies. This morphology is strongly reminiscent of the well-known “beads on a string” mode of star formation observed on kpc-scales in the arms of spiral galaxies, resonance rings, and in tidal tails between interacting galaxies. Nevertheless, the arrangement of this star formation relative to the nuclei of the two galaxies is difficult to interpret in a dynamical sense, as no known “beads on a string” systems associated with kpc-scale tidal interactions exhibit such lopsided morphology relative to the merger participants. In this Letter we present the images and follow-up spectroscopy, and discuss possible physical interpretations for the unique arrangement of the young stellar clusters. While we suggest that this morphology is likely to be dynamically short-lived, a more quantitative understanding awaits necessary multiwavelength follow-up, including optical integral field spectroscopy, ALMA sub-mm interferometry, and Chandra X-ray imaging.

Merging to Dodge Taxes?

This paper investigates whether tax evasion creates incentives among firms to reorganize their production under Value Added Tax (VAT). The VAT is the world’s most popular consumption tax and is considered revenue efficient since cross-reporting of firm-to-firm transactions facilitates selfenforcement. However, the ability to evade tax on consumer transactions creates incentives for the last two firms in the production chain to integrate vertically. In this paper, I test this hypothesis by using a quasi-experiment in India where the sales tax was replaced with VAT in a staggered manner between 2003 and 2008, changing tax evasion opportunities along the production chain. A differencesin-differences analysis reveals that after the reform, treated firms sourced more “upstream” products and had a greater vertical mergers, indicating greater vertical integration under VAT. In addition, the effect is largest for firms that are closest to final demand indicating that tax-evasion is one of the channels. Overall, the results suggest that VAT is no longer production efficient in settings of low compliance.
Psychometric Properties ofDecision to Study Abroad Attributesamong International Edu-tourists from Emerging Economies

This article developed and validates the psychometric properties of attributes that influences edutourists from emerging economies to study in emerging country (AISE) in respect to Malaysia. A survey was done on 1000 international edu-tourists from Africa, Asia and Middle-East in 13 Malaysian edu-tourism institutions. The structure of the underlying dimensions of decision to study abroad was framed based on the Push andPull theory and literature. Reliability analysis, exploratory, and confirmatory factor analysis were applied to investigate internal consistency and construct validity of the AISE model using SPSS and Analysis of Moment Structure version 22. The Composite Reliability (CR) and Average Variance Extracted (AVE) were examined to determine the construct reliability and convergent validity. Result of exploratory factor analysis showed that four dimensions emerged with 20 corresponding items. The confirmatory factor analysis confirmed a three-dimensional model with14 corresponding indicators of a good fit. Dimensions in the final model include: Social-cultural factor, Economic factor, and Career development with valid Cronbach’s Alpha values and a good construct reliability. The value of the AVE shows that the AISE model has adequate convergent validity. Since the focus of the Malaysian government is to attract 200, 000 international edu-tourists by the year 2020. Factors capable of determining international edu-tourists from other emerging countries to decide to study abroad in Malaysia need to be identified. This study suggests a three-dimensional AISE model capable of explaining the decision to study abroad behaviour of international edu-tourists from emerging economies.
The Effect of Principals’ Instructional Leadership Roles on Students’ Academic Achievement As Perceived By Teachers: The Case of Secondary Schools in Sidama Zone

The quality of school principals can have a significant effect on students’ academic achievement.The purpose of this study was to assess the effect of principals’ leadership roles in students’ academic achievement. The descriptive Survey design was employed. For this study from 14 secondary schools, 256 teachers and grade 10 students’ Ethiopian General Secondary Education Certificate Examination (EGSECE) Grade Point Average (GPA) were taken. Questionnaire, interview and document analysis were used as data gathering instrument. The study findings indicated that principals’ role in defining the mission and promoting positive school climates were not adequately done in Sidama Zone secondary schools. However, it was found that principals’ leadership role of managing instructional program was perceived by teachers as effective and implemented at higher level. it was also found that there was a significant and positive relationship between principal’s instructional leadership role implementations and students’ achievement. On top of that it was reported that managing instructional program as a role of instructional leaders is the major predictor on students’ academic achievement and followed by promoting positive school climate role and defining school mission and goal.
Management of Amniocentesis in High Risk Pregnancies and The Evaluation of the Results

OBJECTIVE: To evaluate amniocentesis results applied to high risk pregnancies in our clinic. STUDY DESIGN: In this study, we have perf ormed amniocentesis in 16th-24th weeks of 447 pregnancies who had previous history of chromosomally abnormal fetus, high risk in triple test screening, in which abnomal fetus was seen in ultrasonography, high maternal anxiety, and maternal age 35 years old and above. Cytogenetic analyses were applied to all specimens. RESULTS: Appropriate amount of amniotic fluid was obtained by 98.65%, the successful culture rate was 97.31%, cardocentesis was applied to only one case of 12 cases in which no prolif eration was detected in culture The cordocentesis result was 47XX+18. According to cytogenetic evaluation results, chromosomal abnormality was detected in 29 cases (6.65%). In 7 patients Trisomy 21, in 3 cases Trisomy 18, in one case Trisomy 13, in 3 cases triploidy (69,XXX), in one case mosaicism (46XY/47XYY), in 5 cases translocation, in 9 cases inversion type chromosomal abnormality was detected. After 447 amniocentesis, 5 (1.11%) fetal losses developed. In 2 cases the leakage of amniotic fluid, in one case premature rupture of membranes, in one case cramps and vaginal bleeding and in only one case spontaneous abortus was detected. When the maternal educational level of the cases were evaluated, it was f ound that about one half of the cases had high level education. CONCLUSIONS: If amniocentesis is carried out by highly skilled physicians and if optimal culture conditions are available, amniocentesis is avaluable invasive prenatal diagnosis method with high accuracy and safety, with minimal complications.
Crowded Human Detection via an Anchor-pair Network

This paper presents an anchor-pair network for crowded human detection, which can overcome and solve the difficulties caused by occlusion in crowded scenes. Specifically, we use a function-aware network structure to extract more distinctive and discriminative features for head and full-body respectively, and then a CNN module is also exploited to fuse the features by learning the correlations between head and full-body to reduce crowd errors. Meanwhile, a novel paired form for anchors, denoted as anchor-pair, is proposed to estimate the head regions and full-body regions simultaneously. Furthermore, a new ingenious Joint-NMS is introduced to perform on the detected head and full-body box pairs, which produces significant performance improvement in heavily occluded scenarios at tiny computational cost. Our anchor-pair network achieves a state-of-the-art result on the CrowdHuman dataset which reduces the MR−2 to 55.43%, achieving 11.59% relative improvement over our dataset baseline.
Appendiceal Diverticulitis Presenting with Clinical Features of Acute Appendicitis: Case Report and Literature Review

Introduction: Appendiceal diverticulitis is a rare entity that can mimic acute appendicitis. Differentiation between the two pathologies is necessary due to the high risk of perforation in the case of diverticulitis. Case Report: A case of appendiceal diverticulitis presenting with clinical features of acute appendicitis. Laboratory results showed elevated inflammatory markers, and Computed Tomography (CT) scan showed uncomplicated acute appendicitis. Laparoscopic appendectomy was done, however macroscopic examination showed inflamed diverticulum. Pathohistological analysis displayed an early appendicular diverticulitis. Discussion: We evidenced type 1 appendiceal diverticular disease according to Phillips et al. classification. Diagnosis is based on clinical evaluation, and imaging suggestive of diverticulitis. Appendectomy is the treatment of choice. It can be performed with laparoscopy or laparotomy without any delay. Meticulous examination of abdominal cavity and thorough histological examination of the entire removed appendix are essential due to the higher association with malignancy. Conclusion: Acute appendiceal diverticulitis is a rare disease. Its incidence, risk of perforation and bleeding are not well known comparing to the diverticular disease of the colon. Appendectomy is done even in the case of incidental finding of appendiceal diverticula in asymptomatic patients to avoid the high risk of perforation.
EXIT-SITE INFECTIONS IN PERITONEAL DIALYSIS: PREDICTIVE FACTORS FOR ADVERSE OUTCOMES

Les données du registre des événements ESI (n = 126, chez 74 patients) ont été récupérées. Les protocoles ESI ont suivi les directives internationales standard. Un contrôle qualité systématique est effectué. Le suivi médian était de 29,1 mois (14,0 à 47,4). Dans cette population, les résultats défavorables du taux de tunellites (TI) et du taux de péritonite étaient respectivement de 0,12 et 0,13 patient / an. Le sexe masculin (0,048), l’âge (0,007) et l’agent Staphylococcus aureus (0,006) étaient prédictifs de l’IT, l’IT là où la mise obligée en DP et des taux faibles d’albumine étaient des facteurs prédictifs de la péritonite. Après avoir groupé les ESI en fonction de la date d’apparition de l’infection (groupe 1: 2008 à 2012, groupe 2: 2013 à 2017 et groupe 3: 2018), une augmentation substantielle de l’IT en 2018 était évidente (p <0,001 lorsque le groupe de comparaison 3 vs 1 et 0,005 en comparant les groupes 2 et 3).
Entrepreneurial Competencies and Micro, Small and Medium Enterprises’ Performance in Nigeria

This study was on entrepreneurial competencies and performance of Micro, Small and Medium Scale Enterprises (MSMEs) in Nigeria. The study was a survey with questionnaire as instrument for data collection. The study’s population was 1,319,607 entrepreneurs while the sample 400 was determined using Taro Yamane formular. The data obtained in the study were analyzed with both simple and multiple regressions. The findings of the study indicated that about 51.4% of the variance in MSMEs performance was attributable to entrepreneurs’ innovation skills; about 33.6% of the variance in success of MSMEs was attributable to ability of entrepreneurs to generate ideas; about 47% of the variance in performance of MSMEs was attributable to risk taking; about 50.1% of the variance in MSMEs performance was attributable to entrepreneurs’ creativity and that about 37.1% of the variance in of performance of MSMEs was attributable to the entrepreneurs’ ability to envision opportunities in the business environment. It was recommended that since entrepreneurial competencies can determine success in entrepreneurship, it is essential for entrepreneurs to consider acquiring useful skills before venturing into business; that existing entrepreneurs should avail themselves of various training programs for all manners of business executive to sharpen their management skills in order to improve performance of their business and that government should step up efforts at training entrepreneurs in all business lines and that encouragement should be given to competent entrepreneurs by way of contract award to spur up others into fully embracing training programmes aimed at improving their business fortune.
