Authors: Kumar Jha Ravi , Revankar Vivek , Singh Rajawat Mahtab , J Sreenivas.
Published: March 2022

Aims & Objectives: To identify patient and stricture characteristics predicting failure after direct vision internal urethrotomy (DVIU) for single
and short (<2 cm) bulbar urethral strictures.
Materials & methods: We retrospectively analysed 1260 adult patients who underwent DVIU between September 2007 to January 2021 in the
Department of Urology,Institute of Nephrourology(INU),Bangalore. The patients' demographics and stricture characteristics were analysed. The
primary outcome was procedure failure, dened as the need for regular self-dilatation (RSD), redo DVIU or substitution urethroplasty. Predictors
of failure were analysed. For association between categorical variables, the chi-square test was used, while the Student's t-test was used for
comparing means between groups. Logistic regression analysis was used to determine independent predictors of failure after DVIU. All statistical
analysis was performed using SPSS statistical software, with a P< 0.05 considered to indicate statistical signicance.
Results & Observations:In all,1260 adult patients with a mean (SD) age of 48.3 years were included. The main causes of stricture were idiopathic
followed by iatrogenic in 48.3% and 29.4 % of patients, respectively. Most patients presented with obstructive lower urinary tract symptoms
(64.5%) and strictures were proximal bulbar, i.e. just close to the external urethral sphincter, in 38.3%. The median (range) follow-up duration was
24 (8-127) months. In 60.1% patients did not require any further instrumentation, while RSD was maintained in 28.3%,patients. On multivariate
analysis, older age at presentation [odds ratio (OR) 1.014; P = 0.02], obesity (OR 1.624; P = 0.013), and idiopathic strictures (OR 3.102; P = 0.035)
were independent predictors of failure after DVIU.
Conclusions:The failure rate after DVIU accounted for 39.9 % of our present study with older age at presentation, obesity, and idiopathic strictures
independent predictors of failure after DVIU. This information is important in counselling patients before surgery.

Published: March 2022

Background: Several studies have been done to explore the clinical presentation and management of breast cancer. However, large unexplored
area lies in the histopathological diagnosis of breast cancer, which determines both the choice of therapeutic management and also aids in
determining the prognosis. This study was carried out to evaluate the role of WT1 expression in breast cancer.
Methods: This retrospective study was carried out among 100 parafn blocks of histologically proven invasive breast cancer specimens. WT1
immunohistochemical staining was done on all the hundred cases, while ER, PR and HER-2/NEU status was studied in 93 cases.WT1 expression
was assessed in breast carcinoma and its expression was correlated with known histopathological prognostic factors.
Results:The mean age of the participants was 56 years. Invasive carcinoma- No special type (NST) was the most common histological type in 84%
cases. The maximum number of cases belonged to T2 category (65 %). ER was positive in 53 cases, PR was positive in 40 cases, while HER2/neu
was positive in 30 cases. WT1 expression was positive in 30% of the slides and was identied in the nuclei of tumor cells and the expression varied
between the tumors.WT1 expression was found to be higher in patients with tumor size above 5cm (61.9%) and positive lymph nodal status. (p
value <0.005).
Conclusion: Evaluating WT1 expression with more molecular markers prospectively with a longer duration of follow up and assessing the
survival rates will provide a better insight and validate the ndings of this study.

Authors: Singh Prashant Ranjan , Bharat Singh Sandesh , Gupta Ashutosh
Published: March 2022

Background: Inguinal hernias are one most common problem dealt by general surgeons and have signicant morbidity and mortality. In the
developed countries, almost all of the inguinal hernias are recognized early and present early in the course of disease to the surgeon. However, in
developing countries, quite a considerable percentage of it is not repaired leading to a higher incidence of morbidity and mortality. Hence, we
planned this study to understand the clinico-epidemiologic prole of inguinal hernia in rural medical college in northern India.
Methodology: This is a descriptive epidemiological, prospective study carried out in rural medical college. All patients who presented to the
surgical wards and outpatient with a clinical diagnosis of inguinal hernia were included in the study.
Results:Among the 92 patients included in the study, most of them were men (88) with a mean age of around 44 years, married (85) and farmer (48)
by occupation. All the patients of inguinal hernia presented with the complaints of lump above the inguinal crease and had predominantly rightsided hernia. 5 patients had family history of hernia. Indirect inguinal hernias were predominant. 3 patients had recurrence of earlier operated
hernia, while 5 patients had hernia on the opposite side. Most of the patients presented late to the hospital due to the lack of awareness of the disease.
Conclusion: Late presentation of disease is the hallmark of this disease in rural areas due to the lack of awareness. Increasing awareness of the
disease among general population will lead to inguinal hernias being detected at earlier stage and will decrease the morbidity due to this disease

Authors: HL Prathiksha , Jodha BS , Khokher Santosh , Rawal Kamlesh
Published: March 2022

BACKGROUND: Gestational weight gain and the body mass index (BMI) of the woman are two important factors for a good perinatal outcome.
Maternal nutrition during pregnancy may also have a lifelong consequence on the baby. AIM:1) To study gestational weight gain in primigravida
women delivering a single live baby.2) To study the association of gestational weight gain with morbidity during pregnancy and perinatal outcome
in primigravida women delivering a single live baby. MATERIALAND METHODS: 500 patients were included in the study. All primigravida in
between 37 to 42 weeks of gestational age were included GWG, BMI and associations with the risks. RESULTS:Women with <18.5, 25- 29.9, >30
BMI had 65.3% of inadequate weight gain, 57.5% of excessive weight gain, 94.9% of excessive weight gain respectively.9.3 %, 3.7% of women
with excessive weight gain showed preeclampsia, GDM respectively. 15.9%,17.4% of women with inadequate weight gain had oligohydramnios
and BNNW admission respectively. 51% of women with excessive weight gain ended up in caesarean section. CONCLUSION: After analysing
all the computed data in the present study, we can conclude that from the beginning of pregnancy, by keeping pre-pregnancy body weight under
control and monitoring increase in gestational body weight within prescribed limits, few adverse outcomes of pregnancy can be prevented.
CLINICAL SIGNIFICANCE: GWG is usually neglected. But increase or decrease in GWG can convert a normal pregnancy to high-risk
pregnancy.

Performance Analysis of Helical Compression spring And Banana or C Shaped
Coil Spring Under Various Loading Conditions
Authors: Bansode Pratiksha P. , Badadhe Avinash
Published: March 2022

Suspension system is one of the major and indispensable subsystems for land vehicles and has functions of providing better road holding, handling, and ride comfort. There are many suspension system types used for automobiles, and MacPherson strut suspension is one of the most widely used suspension system type due to its favorable features like simplicity, low cost, and high performance. However, there exists a drawback of this suspension type; since the coil springs have no ability to absorb lateral forces, undesired dry friction effects on the damper may degrade the ride comfort. As remedy to this drawback, the most popular and contemporary application is the use of coil spring forms which are called side load springs.It is observed that, the vehicle drifts towards one side due to high weight of suspension system. This problem can be
solved by implementation of banana-C shaped coil spring. A banana,C-shaped coil spring is designed in such a way that it, when fitted correctly, exerts an opposing force compensating for the aforementioned side load pressure. This creates a balance and leads to the best possible working conditions for the shock absorber, ensuring a longer lifetime. Creo software was utilized to design the helical compression spring. The static analysis using finite element method has been done in order to find out the detailed load vs. defection of the helical compression spring and banana-shaped coilspring.
Design Analysis and performance evaluation of 3D printed baffle path diverters in hydraulic noise suppressor
Authors: Jadhav Sumit , Mate D. M.
Published: March 2022

The pump in the hydraulic systems is the main source of noise in form of vibrations or pulsations while noise reduction is an important part of pump design still some ripples are produced by the pump termed as pulsations. Pulsations result in line vibrations which cause additional noise. How much ripple the pump produces cannot be changed, so other ways to an average of 50 dB(A) to 60 dB(A) level of noise is often considered to safe, although the noise levels resulting due to pulsations are seen to be in ranges as high as 130 t 0 150 dB(A) that result in hose and piping failures and also results in
damage to components like seals and valves. Through the introduction of a compressible membrane in the path with additional baffles for muffling of the noise the proposed solution is in the form of hydraulic noise reducer that incorporates
both the compressible membrane as well as the baffle path diverter. Objective of paper is carried out the performance evaluation of the hydraulic noise reducer with elastomer membrane for noise reduction mechanism in conjunction to baffle type path diverters to even out the fluid pulsations or ripple to minimal without much pressure drop across the device to achieve minim; pumping losses. The paper discusses the performance evaluation of the diverter. The has been tested to determine mass flow rate and pressure drop. Experimental has been manufactured and test has been conducted to evaluate reduction in noiselevelinwithandwithoutthe3-dprintedbaffle arrangement and comparison has been carried out.

أسلوب مواجهة غير المتزوجة للضغوطات النفسية اليومية وعلاقته بالصلابة النفسية
Authors: الحكاك أ.م.د. وجدان جعفر جواد عبد المهدي
Published: March 2022

سعى البحث الحالي إلى تعرُّف وقياس مستويات أساليب مواجهة الضغوط النفسية اليومية والصلابة النفسية لعينة من تدريسيات جامعة بغداد غير المتزوجات، ثم تعرف العلاقة الارتباطية بين مستويات القياس للمفهومين بحسب استجابات العينة وتفسيرها إحصائياً. وبلغت عينة البحث (150) تدريسية من الإناث من كليات ومراكز جامعة بغداد-الجادرية، بأعمار مختلفة بحسب ما توفر للباحثة من أعداد منهنَّ وتسهيلات في التطبيق للعام الدراسي (2013/2014).

وحدد مفهومي البحث بحسب الأدب النظري تنظيراً وقياساً بالآتي:

مفهوم أساليب مواجهة أحداث الحياة الضاغطة (لعبد السلام علي، 1997): سلسلة من الأحداث الخارجية التي تواجهها المرأة العاملة نتيجة تعاملها مع متطلبات البيئة المحيطة بها، وتفرض عليها سرعة التوافق في مواجهتها لهذه الأحداث لتجنب الآثار النفسية والاجتماعية السلبية، والوصول إلى تحقيق التوافق مع البيئة المحيطة بها.

مفهوم الصلابة النفسية ( للحكاك، 2010 ): قدرة الفرد وفاعليته في مواجهة أحداث الحياة الضاغطة، بإيمان وشجاعة وثقة بالنفس وحصانة وتحمل، لأجل البقاء ثابتاً في وجه الصعوبات الحيوية والأخطار والصدمات والإحباطات والمشكلات النفسية اليومية، مطوراً بذلك أهدافاً واقعية واتجاهات تراكمية شخصية لحل المشكلات الحيوية والتفاعل بسلاسة واحترام، مع الذات والآخرين. وأوصلتنا النتائج التي تم الحصول عليها إلى ما يدل على أن عينة البحث من تدريسيات جامعة بغداد-مجمع الجادرية غير المتزوجات يسلكنَّ ويستعملنَّ الأساليب الإيجابية لمواجهة ضغوطات الحياة اليومية بشكل عام من خلال مواجهتهن لأحداث الحياة الضاغطة بدرجة عالية على المقياس، كما أن العينة تتحلى بقدرٍ عالٍ من الصلابة النفسية بحسب استجابتهن على مقياس الصلابة النفسية. أما العلاقة الارتباطية بين المفهومين فهي عالية بالنتيجة، والتي فسرتها الباحثة من جانبين: أولهما أن تدريسيات جامعة بغداد غير المتزوجات يسلكنَّ ويستعملنَّ أساليب إيجابية لمواجهة ضغوطات الحياة اليومية ارتفعت إيجابيهن في استعمالها إلى حد الصلابة النفسية التي تعدُّ كمخفف أو واق لهنَّ ضد الضغوطات هذه، أما الجانب الثاني يفسره تحليهنَّ بقدرة الصلابة النفسية التي اكتسبنها من الحياة العامة من تربية دينية ومن الحياة العملية والاجتماعية التي يعشنَّها بصعوبة وتَحدٍّ دون زواج مع مسؤولية أسرية وشهادة عليا بسنوات تعب وضغوط وحروب وعمل يومي مضني بساعاته وواجباته، فامتلكنها في شخصيتهُنَّ وساعدتهنَّ كثيراً على مواجهة ضغوط الحياة اليومية بأساليب إيجابية وسهَّلت عليهُنَّ العيش بشكل طبيعي لمجاراة الحياة. ثم قدمت توصيات ومقترحات متعددة تهم المؤسسة التعليمية خاصة والمجتمع بشكل عام خدمة للمسيرة العلمية.
Preparedness of future English teachers as a prerequisite of their professional well-being
Authors:   Constantine the Philosopher University in Nitra, Slovakia, Kovacikova Elena , Hartanska Jana ,   Constantine the Philosopher University in Nitra, Slovakia
Published: March 2022

Qualified English teachers in Slovakia need to earn a master degree in teaching. Their university study in bachelor and master years contain theoretical courses in English linguistics, culture, literature, and English teaching methodology accompanied with compulsory teaching practice. Practicum or teaching practice performed at local training schools are supervised by teacher trainers who cooperate with university methodology teachers. The preparedness of university graduates for their real professions has been recently questioned and criticized by educational authorities and public blaming insufficient or prevailing theoretical university preparation. This paper sheds light on the teaching practice of the future English teachers in Slovakia in order to establish their professional well-being. In particular, it discusses the views of the English teacher trainers collected from interviews on the preparedness of university students (pre-service English teachers) for their teaching professions. The qualitative type of the research, a case study with participants – the interviewed teacher trainers on performance of university students was carried out in 2019. The results displayed in a SWOT analysis reveal the gaps that are to be filled by the university preparation. Moreover, the interpretations are based on the linguistic, intercultural and methodological aspects of preparedness that can mirror the challenges in the university preparation of future English teachers in Slovakia. The results and interpretations might contribute towards building professional well-being within European standards of English teachers and their university preparation and the balance between theory and practice./ Key words: English teacher university preparation, teaching practice, practicum, case study
Dispute Resolution as a Part of Your Merger or Your Acquisition Agreement
Authors: Mathieu Kenneth , Schmeltz Vincent
Published: March 2022

Often overlooked until invoked, the dispute resolution provisions of an acquisition agreement frequently mirror the terms of a lawyer’s last deal. Yet such provisions—including purchase price adjustment clauses, the terms of governing earn-out disputes, and the contract sections outlining the indemnification claims process—often have long-term economic ramifications on the buyers and sellers. In working with corporate lawyers over the years, we have noted that corporate lawyers understand (and give intense thought to) the leverage their clients have, what their clients hope to accomplish in a transaction, and what makes long-term economic sense in drafting an agreement and negotiating more advantageous deal terms. In this article, we hope to bring the same analytical intensity to dispute resolution provisions. While every deal is different and perspectives will vary between buyers’ and sellers’ counsel, we have attempted to inform practitioners of the issues that can arise depending on how the parties design their dispute resolution provisions. Accordingly, we have first set out our views on the current transactional environment and its implications on deal leverage and terms. Then, we have described each of the key deal provisions that we believe fall under the broad rubric of “dispute resolution” provisions. In particular, we have analyzed: (i) Purchase Price Adjustments; (ii) Earnouts; and (iii) Indemnity for Breach of Representations and Warranties.
Venture Capital Investments in China: The Use of Offshore Financing Structures and Corporate Relocations
Authors: Li Jing
Published: March 2022

Based on an analysis of the relevant Chinese laws and regulations governing the corporate governance structure of venture capital (“VC”)-invested firms, as well as a discussion on the feasibility of employing different alternatives to make direct and indirect VC investments in Chinese portfolio firms, this article studies a hand-collected sample consisting of the twenty-nine VCbacked Chinese portfolio firms that have been financed and listed from 1990 to 2005 in order to empirically show how these investments were actually made in practice. The findings show that twenty-three out of the twentynine firms received their VC investments in various offshore holding entities, while only four firms were financed domestically, reflecting the common practice of using offshore investment structures to invest in Chinese firms. Although using such structures can be technically viewed as relocating VCfinanced Chinese firms abroad, doing so is different from strategic corporate relocations motivated by the need to access more efficient legal and economic conditions. Instead of being relocated to the United States, most firms actually move to foreign tax havens, such as the Cayman Islands or the British Virgin Islands. It can be argued that the corporate relocation phenomenon in China’s financings actually reflects more of a contracting technique to circumvent unfavorable Chinese laws and more conveniently implement United States-style contracts. In this sense, and within the particular setting of China, real strategic corporate relocation in VC finance is not really yet an issue.
Private Equity & Private Suits: Using 10B-5 Antifraud Suits to Discipline a Transforming Industry
Authors: Black Kenneth
Published: March 2022

This note demonstrates why private equity will no longer be able to avoid private investor suits as it has (mostly) done in the past and explores the industry’s response to a growing number of investor suits. Notably, the industry has already begun to shift its strategy from regulatory avoidance to regulatory capture, at least in part to avoid investor suits. Given these changes, this note proposes that the best way to maintain discipline in the transforming private equity market is to protect the ability of investors to bring private suits.
