Study on prevalence of bovine mastitis in lactating cows and associated risk factors in and around Areka town, Southern of Ethiopia

A cross-sectional study was conducted from October 2011 to March 2012 on a total of 384 lactating (Zebu 183, Jersey103 and Holstein 93) dairy cows randomly selected from 29 rural kebele in which three small scale dairy farms were included. The study was designed with the objective to determine the prevalence of mastitis and isolate the major bacteria that causes mastitis involved in areka woreda and its surrounding wolayta zone. Milk samples was collected and bacteriological culture was done and further confirmation was done by BIOLOG identification system. The overall prevalence of mastitis in the area was 52.9% (n = 203), out of which 9.4% (n = 36) were clinical and 43.5% (n =167) were sub-clinical cases. Among the isolated bacterial genera, the isolate were Staphylococcus(14.8%), Streptococcus (7.5%), Corynebacterium (0.52%) and coliform (0.25%). Characterization was also under taken and the species recovered were Staphylococcus aureus 136 (54.4%) dominating followed by Streptococcus dysagalactiae 62 (24.8%),Staphylococcus intermidius (8.4%) Streptococcus.uberis 13 (5.2%) Staphylococcus epidermides (4.4%) Streptococcus agalactia 4 (1.6%), Corynebacterium pyogens 2 (0.8%) and Escherichia coli 1 (0.4%). There was no statically significant variation (P>0.05) between breeds and the parity number of the cow, but the prevalence of mastitis was found to be statistically significantly among different age groups and lactation stages (p<0.05). The study shows that mastitis is significant problem of dairy cows in the study area and the major isolated bacteria were contagious pathogens. Therefore, hygienic milking practice, culling of chronically infected cows and hygienic practice in the environment should be followed. Key words: Bovine, mastitis, prevalence, Areka Woreda, SNNPR, Ethiopia.
Postganglionic Sympathetic Discharge in Neonatal Swine

We hypothesized that cardiac and respiratory modulation of postganglionic peroneal activity appeared in an age-related manner. In anesthetized, paralyzed and artificially ventilated piglets, simultaneous recordings of efferent phrenic and peroneal discharges were obtained during hyperoxia(fraction of inspired oxygen, Fio2 = 1.0) and hypoxia (Fio2 = 0.1). Spectral analyses of peroneal and aortic blood pressure signals revealed peaks at the cardiac frequency (3.25-5.0 Hz). Coherence analysis showed that these two signals were highly correlated at those frequencies, providing evidence for baroreceptor entrainment. Statistically significant (p< 0.05) increases of coherence values were observed during hypoxic stimulation. Such results were observed in most animals despite age, and provided evidence of a potent mechanism for insuring vasomotor tone even in newborn animals. In contrast, spontaneous respiration-related peroneal discharges were observed only in animals ≥20 d old. In animals <20 d old, hypoxic stimulation elicited respiration-related discharges in peroneal activity. In many cases, peroneal hypoxic discharges exhibited an immature biphasic response pattern despite the presence of a mature response pattern of phrenic activity. Such findings suggest a developmental lag in the linkages of respiratory and sympathetic controlling networks.
Phases of Childhood in Early Mycenaean Greece

Abstract The paper examines the question of whether or not it is possible to distinguish age grades within childhood in Early Mycenaean Greece. The analysis centres upon burial evidence from the Argolid, the core-area of Mycenaean civilisation, from where the largest amount of material suitable for such an analysis is available. The study concludes that on the basis of the available evidence three major phases can be identified within childhood – up until 1–2 years; 1–2 to 5–6 years and post 5–6 years. These approximate age grades, however, appear to have been somewhat fluid and changed over time.
Spatial Visualization Measurement: A Modification of the Purdue Spatial Visualization Test - Visualization of Rotations.

During the 1999 Fall semester at North Carolina State University, a study was conducted to determine the effectiveness of using trimetric pictorials instead of isometric pictorials on the Purdue Spatial Visualization Test — Visualization of Rotations (Guay, 1977). Undergraduate students enrolled in Graphic Communications courses completed computer versions of the PSVT and the Mental Rotations Test (Vandenberg & Kuse, 1978) during the first six weeks of classes. The instruments were used to record student responses and response times as well as information on gender, current major, and number of previous graphics courses completed. The control group completed the original version of the PSVT (isometric pictorials) and the MRT. The experimental group completed a revised version of the PSVT (trimetric pictorials) and the MRT. The researcher hypothesized that trimetric pictorials would be a more sensitive predictor of spatial visualization ability.
On Modeling and Analysis of MIMO Wireless Mesh Networks with Triangular Overlay Topology

Multiple input multiple output (MIMO) wireless mesh networks (WMNs) aim to provide the last-mile broadband wireless access to the Internet. Along with the algorithmic development for WMNs, some fundamental mathematical problems also emerge in various aspects such as routing, scheduling, and channel assignment, all of which require an effective mathematical model and rigorous analysis of network properties. In this paper, we propose to employ Cartesian product of graphs (CPG) as a multichannel modeling approach and explore a set of unique properties of triangular WMNs. In each layer of CPG with a single channel, we design a node coordinate scheme that retains the symmetric property of triangular meshes and develop a function for the assignment of node identity numbers based on their coordinates. We also derive a necessary-sufficient condition for interference-free links and combinatorial formulas to determine the number of the shortest paths for channel realization in triangular WMNs.

Nigel: A Systemic Grammar for Text Generation.

Abstract : Programming a computer to write text which meets a prior need is a challenging research task. As part of such research, Nigel, a large programmed grammar of English, has been created in the framework of systemic linguistics begun by Halliday. In addition to specifying function and structures of English, Nigel has a novel semantic stratum which specifies the situations in which each grammatical feature should be used. The report consists of three papers on Nigel: an introductory overview, the script of a demonstration of its use in generation, and an exposition of how Nigel relates to the systemic framework. Although the effort to develop Nigel is significant both as computer science research and as linguistic inquiry the outlook of the report is oriented to its linguistic significance.
Improving Knowledge on The Prevention of Dengue Hemorrhagic Fever Among Elementary School Students in Jakarta, Indonesia: A Quasi Experimental Study

Dengue Hemorrhagic Fever (DHF) remains as one of major public health problems in Indonesia. During the years, Jakarta has become the province with high number of DHF cases. To reduce the cases, DHF prevention initiative can be done through health education. The objective of this study was to assess the knowledge of elementary school students in Jakarta, Indonesia on the prevention of DHF by giving the health education as the intervention. A quasi experimental study with pre and post-test design was carried out among 5 and 6 grades of elementary school students in 21 schools in Jakarta region. Seven schools received poster intervention and other 7 schools received flip chart intervention, while 7 schools were determined as the control group. Data from 630 students were collected to be analyzed during the study. The result showed that the students in the intervention groups had the likelihood to improve their knowledge 2.415 times (95% confidence interval: 1.620 – 3.601) for poster presentation and 1.527 times (95% confidence interval: 1.038 – 2.246) for flip chart when it was compared to the students who did not received any intervention (control group). Although both interventions (poster and flip chart) have indicated the significant effect in increasing overall knowledge, but implementing health education through poster was more effective than flip chart to spread information among students. The students had a good knowledge on control measures to prevent DHF, but still need more improvement about action to tackle DHF patient in early stage of DHF symptoms such as caring and seeking health care. In conclusion, providing health education such as poster and flip chart to the elementary school students as one of the vulnerable group to DHF might be beneficial for the prevention of DHF.

Varicocele Surgery Improves Sperm Count in Infertile Oligospermic Patients and so Improves Fertility; A Study in a Tertiary Care Hospital

The objective of this study was to find out the role of varicocele surgery in oligospermic infertile patients. It was a prospective and descriptive study carried out in Surgical Unit-I, Abbasi Shaheed Hospital and Karachi Medical and Dental College (KMDC), Karachi from April 2004 to March 2014. In this study, all patients of infertility due to low sperm count having bilateral varicocele were included while those patients having azoospermia or patients with unilateral varicocele were excluded. All patients were clinically assessed for bilateral varicocele and confirmed by ultrasonography of scrotum and relevant investigations were done. Patients were prepared for varicocele surgery and ligation of pampiniform plexus done. Semenanalysis were done during follow up and results were analyzed on SPSS version 14. Total fifty seven patients (n=57) were included in which age range was 20 to 30 years in 33.3%, 31 to 40 years in 42.1%, 41 to 50 years in 19.3% and 51 years to onwards in 05.3% patients only. Chronic smoking was found in 68.4% patients while 31.6% were nonsmokers. Normal testes was found in 77.19% while 22.81% had smaller (atrophied) testes. Very low sperm count was in 15.79%, 50.88% had low sperm count and 33.33% had near normal sperm count. All patients were operated for bilateral varicocele and discharged. Follow-up semen analysis showed improvement and semen analysis became normal in 19.3% after six months, 21.05% after nine months and 36.84% after one year of surgery while 22.81% had no improvement even after one year of surgery. Thus, patients with bilateral varicocele having low sperm count showed improvement in sperm count after varicocele surgery and so infertile patients may become fertile after varicocele surgery.
Effects of Huanglian Jiedu Decoction (HLJDD) on fever induced by lipopolysaccharide and inflammation induced by carrageenan

This study aimed to investigate the antifebrile and anti-inflammatory effect of Huanglian Jiedu Decoction (HLJDD). The rabbits received intravenous injection of lipopolysaccharide (LPS) after orally administered with HLJDD and the rectal temperatures of rabbits were monitored. The concentrations of interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) in serum were assayed using rabbit IL-1β and TNF-α enzyme-linked immunosorbent assay (ELISA) kits. Carrageenan-induced paw edema in rats and the anti-inflammatory effects of HLJDD were also explored. HLJDD treatment group resulted in a significant fall in body temperature in biphasic fever peak (p 0.05). HLJDD treatment group reduced the concentrations of IL-1β in serum at time 1 and 3 h to control febrile responses. Moreover, paw edema of carrageenan-treated rats were significantly attenuated in rats pretreated with HLJDD. Mechanistic studies showed that HLJDD effectively decreased expressions of COX-2 and inducible nitric oxide synthase (iNOS) proteins. These results suggested that HLJDD would be a valuable candidate for further investigation as a new anti-arthritic drug. Key words: Lipopolysaccharide, Huanglian Jiedu Decoction (HLJDD), anti-inflammatory, interleukin-1 beta, tumor necrosis factor alpha.

Words of Experience: Semantic Content Analysis and Individual Differences among Successful Second Language Learners

Individual differences (IDs) in second language (L2) learning have traditionally been studied as separate, isolated variables (Dornyei, 2005), but this reductionist approach has led to a fragmented and inconclusive understanding of how IDs influence L2 learning. The present study takes a different approach to IDs by starting at the level of L2 learning experience and identifying the most basic differences between learners. To do this, a new L2 experience methodology is introduced. Participants are 123 matriculated non-native English speaking students at two urban universities in the South. First, learners were interviewed following a strict interview protocol which ensured that all learners received the same input in the same setting. Next, the interviews were analyzed using the Linguistic Inquiry and Word Count software (Pennebaker, Booth, & Francis, 2007), which provides quantitative output showing the types and frequency of psychosocial words each learner produced. These psychosocial semantic categories then formed the basis of a cluster analysis that identified groups of learners who use similar semantic categories. Learners who tend to use similar psychosocial words to describe their L2 learning experience are assumed to share a similar approach to L2 learning and are grouped together into L2 learning profiles. Results show that these participants can be grouped into three types of successful L2 experiences: Doing, Thinking, and Feeling. An ANOVA and follow-up ad hoc statistical tests reveal significant differences in admissions TOEFL scores among these groups of students, suggesting that learners who describe their L2 experience differently do in fact show significant differential performance. Qualitative analysis of interview transcripts further suggests that the influence of family plays an important role in differential TOEFL scores, and that L2 learning experience may change in important ways over time. Based on the results of the study, a L2 Experience Model of Individual and Social Differences is proposed that accounts for life importance, effort, ability, and L2 experience. Implications of this new methodology and model are discussed, along with suggestions for future research, teaching, and L2 learning.

Art and design is still a gendered school subject

Gender disparity in the take-up of post-compulsory school art, leading to the predominance of girls at GCSE and A-level, appears to be linked to the perception that the subject offers few career prospects, and to the notion that boys dislike drawing and painting. This paper derives from a case study of a London secondary school art department during 2010/11. One aspect of the research examines the way art remains a feminine, marginalised subject despite its relevance to the increasingly successful creative industries. A central finding is that good attainment at GCSE still relies heavily on a demanding homework load and copious preparatory studies, both off-putting to students, particularly boys.
Black Adolescent Females’ Perceptions of Racial Discrimination When Accessing Reproductive and General Health Care

Adolescents, like adults, frequently experience discrimination, which can be particularly salient in the context of reproductive health care. We examined urban Black adolescent females’ perceived experiences of racial discrimination during reproductive health care encounters. Structured face-to-face interviews were conducted with female African American patients, from age 13 through 20, who obtained reproductive health care services at a single site. Twenty-four participants were enrolled. All were in or graduated from high school, with a mean age of 16.8 years. These young Black women reported infrequent race-based discrimination in the health care setting; however, many reported commonly experiencing discrimination in other places. An awareness of the discrimination that minority young women experience in non–health care settings can help providers demonstrate cultural humility when addressing such concerns with their patients. With this information, providers can provide anticipatory guidance and the tools necessary to navigate complex social systems.
