Problems In Nonlinear Homogenization: Bounds, Estimates, Macroscopic Instabilities, And Post-Bifurcation Response

PROBLEMS IN NONLINEAR HOMOGENIZATION: BOUNDS, ESTIMATES, MACROSCOPIC INSTABILITIES, AND POST-BIFURCATION RESPONSE Joshua Robert Furer Pedro Ponte Castañeda Due to the ever-growing interest in composite materials designed with complex microstructures and capable of possessing exotic properties, it has become increasingly important to be able to accurately capture the interplay between the macroscopic response and the underlying microstructure, as the former is greatly influenced by the latter. Of the different approaches available, this thesis is concerned with the use of nonlinear homogenization to study the effective response of composites. We look to illustrate the effect that constitutive assumptions have on the methods by which such estimates can be obtained, and on the actual effective, or homogenized, response of the material. For materials whose constitutive response is governed by convex functions, we show how the convexity itself can be utilized to obtain rigorous bounds and improved estimates. We prove the optimality of variational linear comparison bounds over the class of nonlinear anisotropic composites with linearly isotropic response and introduce a new symmetric fully optimized second-order method which is able to generate estimates for the effective response of nonlinear composites. On the other hand, convexity is often inconsistent with certain physical requirements (e.g. objectivity). Such is the case of hyperelasticity, where the lack of convexity of the stored-energy functions has long been known to lead to the development of instabilities. We present a framework for studying the post-bifurcation response of such systems and apply it to a specific class of reinforced hyperelastic composites under general three-dimensional loading conditions. We also consider the class of magnetoelastic composites, which consist of hyperelastic materials that are also magnetically susceptible. Unlike in the case of hyperelasticity, there lacks a complete mathematical framework for obtaining the effective response of such materials, and researchers have only begun to investigate the potential for instabilities in these materials. We therefore generalize the same methodology used successfully in the purely mechanical context to study the post-bifurcation behavior of magneto-elastic composites. This in part requires a rigorous generalization of the theoretical aspects that underlie the iii method. We then calculate the post-bifurcation response of a magneto-elastic material under general plane-strain loading conditions with a magnetic field applied in the plane of deformation.

Legal Framework to Gender-Based Violence, Sexual and Reproductive Health Rights of Indigenous Women in Cameroon

Men and women have different health profiles which necessitate different health needs, as a result of their biology and their distinct status in society. Discrimination and harmful traditional practices in many societies in the global south further affect the reproductive health of indigenous women. The paper will highlight discrimination against women in patriarchal indigenous communities in Cameroon. The paper focuses on violations that affect women’s reproductive health. The paper will discuss these violations in light of the country’s commitment to Sustainable Development Goal No. 3 on good health and well-being and Goal No. 5 on gender equality. The paper will also highlight the national and international laws addressing the right to the reproductive health of indigenous women. It will also examine gender-sensitive interventions, legislation and policies put in place by the indigenous community and the Government of Cameroon if any. The paper will end with conclusion and suggestions/recommendations on ways to improve the reproductive health of indigenous women in Cameroon.
What teachers never have time to do: peer observation as professional learning

ABSTRACT This case study involved an urban elementary school’s implementation of a peer-observation professional learning protocol, collegial visits (CVs). The study sought teachers’ perceptions of CVs as a professional learning format, whether CVs aligned with contemporary professional learning expectations, how and in what ways CVs influenced social capital and what conditions enhanced or detracted from the implementation of collegial visits. Data included interviews with 13 educators (9 teachers; 4 leaders), implementation artefacts and rubric scores from leadership walkthroughs. Results indicated that CVs, supported by enhancing conditions and resisted by many fewer detracting conditions, positively impacted instruction. Teachers perceived CVs positively, and CVs aligned strongly with standards. CVs increased social capital by improving instructional practices across the school’s classrooms (at scale), increasing collective ownership and helping teachers to view colleagues as resources.
Financial distress determinants among SMEs: empirical evidence from Sweden

The purpose of this study is to empirically investigate determinants of financial distress among small and medium-sized enterprises (SMEs) during the global financial crisis and post-crisis periods. ,Several statistical methods, including multiple binary logistic regression, were used to analyse a longitudinal cross-sectional panel data set of 3,865 Swedish SMEs operating in five industries over the 2008–2015 period. ,The results suggest that financial distress is influenced by macroeconomic conditions (i.e. the global financial crisis) and, in particular, by various firm-specific characteristics (i.e. performance, financial leverage and financial distress in previous year). However, firm size and industry affiliation have no significant relationship with financial distress. ,Due to data availability, this study is limited to a sample of Swedish SMEs in five industries covering eight years. Further research could examine the generalizability of these findings by investigating other firms operating in other industries and other countries. ,This study is the first to examine determinants of financial distress among SMEs operating in Sweden using data from a large-scale longitudinal cross-sectional database.
Clinico hematological profile of pancytopenia in pediatric patients: an institutional experience in North Himalayan region of India

Background: Pancytopenia is a common clinical pattern with an extensive differential diagnosis, but literature search shows only limited studies of pancytopenia in Pediatrics patients in Uttarakhand state of India. The present study was therefore conducted to study the spectrum of pancytopenia with bone marrow and haematological profile in Pediatrics patients in this north Himalayan state of India. Methods: Prospective observational study was conducted in the Department of Pediatrics in the teaching institute situated in Uttarakhand state of India over a period of 12 months. The study included all the patients of pancytopenia below 18 years of age who underwent bone marrow examination after written informed consent. Results: The study included total 50 pediatrics patients of pancytopenia with male to female ratio of 1.38:1. The mean age of patients was 10.58±4.94 with median age of 12 years. Mean hemoglobin was 5.31±2.09 g/dl, total leukocyte count was 2492.68±941.76/mm3, platelet count was 34724±26423/mm3, mean corpuscular volume was 90.95±16.65 fl, mean corpuscular hemoglobin was 30.11±6.07 pg, mean corpuscular hemoglobin concentration was 33.06±1.65% and reticulocyte count was 1.21±1.10%. Nutritional deficiency (28%) was the most common cause for pancytopenia followed by aplastic anemia (24%). Megaloblastic anemia was the commonest cause of nutritional deficiency anemia (71.42%) with pancytopenia. Conclusions: Pancytopenia is an important presentation in Pediatrics population with the most common cause being nutritional anemia and aplastic anemia. Megaloblastic anemia is the commonest cause of nutritional anemia with pancytopenia. The clinicians should be aware of spectrum of pancytopenia with clinical and haematological presentation in Pediatrics patients of this region so as to avoid unnecessary work ups and delay in treatment.
GRANULOMATOUS MASTITIS IS NOT ALWAYS TUBERCULAR: ROLE OF FINE NEEDLE ASPIRATION CYTOLOGY IN EVALUATION OF GRANULOMATOUS MASTITIS

INTRODUCTION AND OBJECTIVES: Granulomatous mastitis is rare chronic inflammatory benign breast lesion, which clinically and radiologically resembles carcinoma breast thus creating a diagnostic dilemma. The term granulomatous mastitis includes two broad categories namely specific granulomatous mastitis for which aetiological factors can be defined such as infectious causes like Mycobacterium tuberculosis, blastomycosis, cryptococcosis, histoplasmosis, actinomycosis and filarial infection. Other factors include association with autoimmunue diseases such as Wegner’s granulomatosis and giant cell arteritis and there are other rare causes such as include duct ectasia, foreign body reaction and fat necrosis which also leads to granulomatous lesions of breast. Cytological features of granulomatous mastitis(GM) have not been widely discussed and described in literature, so through this study we have made an attempt to thoroughly discuss cytological spectrum of granulomatous mastitis. MATERIALS AND METHODS: A retrospective study was performed over a period of four years from 2016 to 2019. A total of 465 cases of breast lump reported to cytopathology section out of which 24 cases of GM diagnosed on FNAC were included in our study. Results of Erythrocyte sedimentation rate (ESR) and Mantoux test along with TB-PCR were recorded. FNAC slides were retrieved pertaining to study period. Granulomatous lesions of breast were further categorized broadly into IGM/ NGM, granulomatous mastitis without caseous necrosis and tubercular mastitis where diagnosis were made definite on basis of demonstration of AFB or positive TB-PCR . RESULTS: Patient age ranged from 23 years to 55 years with the mean age of 36.6 years with maximum of patients falling in second decade followed by third decade. Granulomatous lesions were broadly categorized into Idiopathic/ Non specific granulomatous mastitis(11 cases,45.8%), GM with caseous necrosis(8 cases, 33.3%) and tubercular mastitis(5 cases, 20.9%). Histopathology was available in 7 cases(29.2%). TB-PCR was sent in all cases of granulomatous mastitis diagnosed on cytology and was positive in 10 cases(41.7%). CONCLUSION: Idiopathic granulomatous mastitis and tubercular mastitis are rare inflammatory diseases of breast which mimic malignancy clinically and radiologically. FNAC plays important role in diagnosis of granulomatous diseases of breast and also their differentiation from malignant tumors. Tubercular mastitis needs to be differentiated from IGM since treatment options are different in both the cases. Cytopathology plays an important role in differentiationg both the diseases supplemented by radiological and microbiological investigations. The present study thus highlights the importance of FNAC as an infalliable tool in diagnosis of granulomatous mastitis and its differentiation from neoplastic lesions of breast thus avoiding time consuming histopathological work up of cases.

Work-related injuries in a midwestern manufacturing facility

Background: Shift work, or working outside of normal daytime working hours, has been shown to be associated with increased risk of occupational injury. Few studies have focused on the effects of shift work in manufacturing, even though manufacturing has a large number of shift workers. This study aims to fill this gap by examining the effect of shift on injury incidence among workers in a large manufacturing facility. Methods: Employment and injury data were collected from a large Midwestern manufacturing facility for the years of 2011 and 2012. Descriptive statistics and Poisson regression were used to determine the best predictors of injury, with shift being our primary exposure of interest. Other predictors considered were gender, age, job classification, job tenure, and racial category. Results: The most significant predictors of injury were job tenure and gender. After controlling for gender and tenure, we found that second shift workers had a marginally higher rate of injury than first shift workers (IRR 1.10, 95% CI 0.95 – 1.27). The injury rate for third shift workers was not significantly different than first shift workers (IRR 0.91, 95% CI 0.73 – 1.14). Compared to workers with 0-12 months of experience, each group of higher tenured workers had lower injury rates. Conclusions: Although not statistically significant, shift was a strong predictor of increased injury incidence, even after controlling for gender and tenure. Our findings suggest that additional research and injury prevention efforts are needed not only for shift workers, but for low tenured workers in manufacturing as well.
Intramedullary Interlocking Nailing for Long Bone Fractures of the Lower Limbs: Our Experience with Free-hand Locking

Aims: To see the pattern of interlocking nailing used for fractures of lower limb’s long bones in terms of the bone affected, laterality, age distribution, sex distribution, pattern of locking and early outcome. Study Design: The study is a retrospective cross sectional study conducted over three years from April 2013 to march 2016 in a private hospital in Kano, North western Nigeria. Methodology: All patients that had intramedullary nailing for femoral and/or tibial fractures within the period of study, were recruited. Theatre register was used to extract the file numbers of the patients. The folders were retrieved and the information extracted. The Data was analysed using XLStat software. Results: The age ranges from 19 -70 years with a majority between 20-39 years. There is only one person below the age of twenty and is in the male category. There were a total of 87 procedures Original Research Article Muhammad and Mamuda; JAMPS, 14(4): 1-7, 2017; Article no.JAMPS. 35079 2 conducted on 81 patients of which 70(86.4%) were males and 11(13.6%) were females. Only 77% of the interlocking nail were locked at both ends, the remaining were locked at one end with the other end abandoned due to difficulty in getting the hole or actually not attempted. Of the 87 nailings, 5 were inappropriately locked outside by the side of the distal nail and 2 were locked distal to the tip of the nail. One femoral and 3 tibial, developed non-union requiring exchange nailing with a larger diameter nail and cancellous bone graft. 6 patients developed surgical site infection which were manage successfully with antibiotics and wound care with only 2 tibial nails requiring conversion to external fixation using Linear Rail system for compression. 70(86%) of the patient were satisfied with their treatment with very good – excellent range of motion, while 11(14%) patient have either of reduce range of motion, anterior knee pain or abnormal gait. Conclusion: Most challenging aspect of the procedure were intraoperative radiography was not available, is correct placement of the distal locking screws. Use of a distal targeting device is the main stay, while using the guide wire to sound the drill bit/screw increases the chances of accurate placement.
Political and personality predispositions and topical contexts matter: Effects of uncivil comments on science news engagement intentions

Building on existing theoretical frameworks for the study of incivility, interactivity, and negativity bias, this study contributes to the growing body of literature on the impact of incivility in online comments. Specifically, it tests incivility’s impact on news engagement intentions; investigates political and personality predispositions’ roles as perceptual filters; and extends this scholarship to the context of multiple scientific news topics. It found that, when dealing with news about two of the more politically divisive technologies—fracking and synthetic biology—ideology moderated the effects of incivility, with uncivil comments encouraging engagement among conservatives but not among liberals. However, in the less politically divisive context of nanotechnology, self-monitoring played a significant role in moderating incivility’s effects: with high self-monitors being more motivated, and low self-monitors less motivated, to share nanotech news after exposure to uncivil comments. These results imply that individual predispositions and topic-specific factors both underlie the impact of incivility on news engagement intentions.
Analysis of lipid profile and atherogenic index in hyperlipidemic rat (Rattus norvegicus Berkenhout, 1769) that given the methanolic extract of Parijoto (Medinilla speciosa)

Diet of high lipids cause hyperlipidemia, which marked by an increase of total cholesterols, triglycerides, LDL-C, and decreasing of HDL-C. Hyperlipidemia lead the occurrence of atherosclerosis, one of factors that trigger cardiovascular disease, as hypertention; coronary heart and stroke. Parijoto (M. speciosa) is endemic plants in Asia with a distribution center in Malaysia, Indonesia and Philippines. Parijoto contain phytochemical components such as flavonoids, saponins and kardenolin. Flavonoid potensial as an antioxidants and can improve the hyperlipidemia condition. This study was aimed to determine lipid profiles and atherogenic index of hyperlipidemic Wistar rats (R. norvegicus Berkenhout, 1769) which given the methanolic extract of Parijoto (M. speciosa).

Can Investment Incentive Crowd Out Innovation? Evidence from China

We analyze the spillover effect of fixed asset investment tax credits on firm innovation. We estimate this effect by exploring China’s value-added tax reform in 2004. The results of difference-in-difference-in-differences (DDD) estimation show that the reform significantly reduces firm innovation, by 9.51%. Moreover, the crowding out effect appears only in firms with intermediate-level financial constraints, consistent with the prediction of our simple model with heterogeneous production technologies and financial constraints. A similar non-monotonic effect also appears in other firm decisions, such as labor input. As innovation is a major driver of economic growth with a positive externality, our results suggest that the fiscal policy of investment incentives may have unintended consequences.
