Preparation of (R)- and (S)-3-Hydroxy-2-(trifluoromethyl)propionic Acid by Resolution with (R,R)- and (S,S)-2-Amino-1-phenylpropane-1,3-diol
Authors: Götzö Stephan P. , Seebach Dieter
Published: April 2022

Racemic 2-trifluoromethyl-3-hydroxypropionic acid (rac-1) is prepared on a 50 g scale from 3,3,3-trifluoropropene in four steps, the overall yield being 40%. A procedure for the resolution of rac-1 with 2-amino-1-phenylpropane-1,3-diol is described (25 g scale). The acids (R)-1 and (S)-1 are isolated, their enantiomer purities determined by GC analysis of the corresponding methyl esters on a chiral column and their chirality senses assigned from an X-ray crystal structure of the salt formed with phenylethylamine. The non-fluorinated analog of 1 is frequently employed as a chiral synthetic building block ('Roche acid').
New Pathways to Precursors of Pentalene

Mechanism of the chorismate dehydratase MqnA, first enzyme of the futalosine pathway
Authors: Archna Archna , Breithaupt Constanze , Nguyen Duc-Anh , Lilie Hauke , Ziegler Jorg , Stubbs Milton T.
Published: April 2022

MqnA, the only chorismate dehydratase known so far, catalyzes the initial step in the biosynthesis of menaquinone via the futalosine pathway. Here we present crystal structures of Streptomyces coelicolor MqnA and its active site variants in complex with chorismate and the product 3-enolpyruvyl-benzoate. Together with activity studies, our data are in line with dehydration proceeding via substrate assisted catalysis, with chorismate acting as catalytic base. Surprisingly, structures of the variant Asn17Asp with co-purified ligand suggest that the enzyme converts to a hydrolase by serendipitous positioning of the carboxyl group. All complex structures presented here exhibit a closed Venus flytrap fold, with the enzyme exploiting the characteristic ligand binding properties of the fold for specific substrate binding and catalysis. The conformational rearrangements that facilitate complete burial of substrate/product, with accompanying topological changes to the enzyme surface, could foster substrate channeling within the biosynthetic pathway.

Published: April 2022

3D printing of biomaterials enables spatial control of drug incorporation during automated manufacturing. This study links bioresponsive release of the anabolic biologic, insulin-like growth factor-I (IGF-I) in response to matrix metalloproteinases (MMP) to 3D printing using the block copolymer of poly(2-methyl-2-oxazoline) and thermoresponsive poly(2-n-propyl-2-oxazine) (POx-b-POzi). For that, a chemo-enzymatic synthesis was deployed, ligating IGF-I enzymatically to a protease sensitive linker (PSL), which was conjugated to a POx-b-POzi copolymer. The product was blended with the plain thermogelling POx-b-POzi hydrogel. MMP exposure of the resulting hydrogel triggered bioactive IGF-I release. The bioresponsive IGF-I containing POx-b-POzi hydrogel system was further detailed for shape control and localized incorporation of IGF-I via extrusion 3D printing for future applications in biomedicine and biofabrication.

Published: April 2022

This paper will focused on effective recognizing and controlling system for Bank locker room which is fully self determining. In cases of robberies, it’s commonly happen that the banned entrance in the locker room area which can be detected by our security system. If the robbery take place the banks are not be capable to recognize the robber due to absence of the proof by using the current human operated security system. Development of various sensors has enabled systems to have preventive and corrective measures in this regard significantly. In order to deliver a concrete security solution for critically important and confidential documents and goods, we proposed an Automated Safety Vault with Double Layered Defense Mechanism. The solution comprised of an Electronic Lock driven by password verification and a Biometric authentication for users using a Finger print scanning and sensing tool. Both of these two layers ensured the authenticity of the user by preventing any unauthorized access to the Vault. The system was then implemented in a prototype scope for testing and validation of the proposals. The implemented system and testing data showed that the Automated Safety Vault with all its security features had successful operation. The specification of the whole system as well as the results is observed and verified.

A FUZZY INVENTORY MODEL WITH EXPONENTIALLY PRICE AND TIME-DEPENDENT DEMAND UNDER EXPONENTIALLY BACKLOGGED SITUATION
Authors: Khanam Zeba
Published: April 2022

In this study, we have proposed a fuzzy inventory model for deteriorating items with exponential price and time-dependent demand under inflation. Shortages are allowed partially with the rate of exponential duration of waiting time up to the arrival of the next lot. The inventory parameters are considered as fuzzy valued. The corresponding problem has been formulated as a nonlinearly constrained optimization problem. A numerical example has been considered to illustrate the model and the significant features of the results are discussed. Finally, based on these examples, sensitivity analyses have been studied by taking one parameter at a time keeping the other parameters as same.
HEAT TRANSFER PROPERTY OF METALLIC NANOFLUIDS – A STUDY
Authors: Das Anirban
Published: April 2022

Prolonged use of domestic and industrial applications gives rise to high heat generation in the systems. Smart materials like nanofluids can be useful to overcome this modern-day problem. In this study we are reporting the water-based nanofluids, to challenge this problem. Due to the availability of water in Bengal, the simplest solution for cooling a machine is to flow water surrounding it. The nanofluids we have synthesized are metallic nanoparticles dispersed in water, which is considered as base fluid. The heat capacity and thermal conductivity of the nanofluids were predicted by the equilibrium molecular dynamics (EMD) simulation. It is observed that dispersed nanoparticles help an enchantment in thermal-conductivity of the fluids whereas the heat capacity decreases by a small value. The low-cost sol-gel method was used to synthesize the Cu and Ag nanoparticles and later disperses the same in distilled water in suitable wt%. Nanofluids were subjected to ultrasonic studies around room temperature. The thermal conductivity of the used fluids is the function of the velocity values of ultrasonic wave propagation through the fluid system. The experimental measured thermal-conductivity values show an enhancement of about 30% in comparison to the base fluid water in ambient temperature.

A NOVEL CONCEPT IN THEORY OF QUADRATIC EQUATION
Authors: Bhattacharyya Prabir Chandra
Published: April 2022

The basic idea of a quadratic equation is one of the most important topics in algebra. The mathematical concept for the method of solution of a quadratic equation is dependent on the advancement of the theory of numbers. The author developed a new concept regarding the method of solution of the quadratic equation based on “Theory of Dynamics of Numbers”. The author determined the inherent nature of one unknown quantity (say x) from the quadratic expression ax2+bx+c of the quadratic equation ax2+bx+c=0 by keeping the structure of the second-degree expression intact and then finding the solution of the quadratic equation using the novel concept of the Theory of Dynamics of Numbers. The author solved any quadratic equation in one unknown number (say x) of the quadratic equation in the form of ax2+bx+c=0, whether the numerical value of the discriminant is b2-4ac≥0 or b2-4ac<0, is real numbers only without using any imaginary numbers. With these new inventive concepts, the author developed new theories in the theory of quadratic equation.

Pengukuran kinerja dengan Six Sigma merupakan pengukuran kinerja proyek yang beralaskan perusahaan data maupun ilmu statistik yang dapat diukur dengan menggunakan variabel-variabel pengukuran yang telah ditetapkan sehingga dapat menghasilkan angka yang menunjukkan kualitas kinerja manajemen proyek. Metode Six Sigma diperlukan pada pengukuran kinerja karena untuk mengetahui kasus apa yang bisa diukur dengan Six Sigma dan tidak bisa diukur, yang mana pada desain eksperimen penulis menyajikan bukti-bukti dengan kasus tertentu untuk mengetahui hasil akhir sebagai perbandingan keunggulan Six Sigma dengan metode lain untuk menghasilkan manajemen proyek yang efisien dan mampu memanifestasikan tahap pelaksanaan proyek yang detail dan efektif. Peneliti menggunakan data primer yang berjudul “A Guide to The Project Management Body of Knowledge PMBOK GUIDE Sixth Edition”. Karenanya dibutuhkan PMBOK sebagai standar acuan untuk mewujudkan keberhasilan proyek yang meliputi 5 fase dan 10 knowledge areas dalam manajemen proyek. Kecenderungan masing-masing knowledge pada PMBOK  lebih berfokus pada perhitungan perencanaan sebelum dilakukan eksekusi terhadap proses produksi, keberhasilan dan kecacatan proses yang tidak semua knowledge area dapat diukur dengan angka menjadi sebab bahwa tidak dapat dilakukan pengukuran kinerja pada masing-masing knowledge melainkan terbatas pada knowledge yang sudah diketahui hasil pengerjaannya di lapangan. Dari semua knowledge area dapat diukur hanya Project Quality Management saja yang dapat diukur dengan metode Six Sigma.

A total of 100 HIV-infected patients aged 13 to 60 years who gave consent and fulfilled the inclusion criteria were enrolled in the study via non-probability consecutive sampling. All patients who had positive HIV antibodies via the Elisa process were considered positive. Samples were examined for fasting lipids by using standard laboratory procedures.

Results: The patients' mean age was 32.7 ± 13.4 ranging between 13-60 years. The total patient population consisted of 71% males and 29% females with a mean BMI of 21.1 ± 3.4 kg/m2. Out of 100, 38% of the study patients had dyslipidemia. The observed prevalence rate of hypertriglyceridemia, hypercholesterolemia, low HDL-C, and high LDL-C were 21%, 30%, 20%, and 16%, respectively. None of the factors were found in significant association with abnormal lipid parameters except the older patients (41-60 years) were at higher risk of hypercholesterolemia [aOR 0.15 (95% CI 0.02-0.92); p=0.04] than the counterpart.

Conclusion: The study has demonstrated that a higher percentage of HIV-infected patients have concomitant dyslipidemia with or without art treatment.

Published: April 2022

Background: Unusual genitourinary activity is categorized by the genital deposit of foreign objects. It has been known for centuries and common etiological factors include sexual stimulation. Psychiatric disorders and intoxication may also be associated. Foreign body retrieval and the evaluation of psychosocial factors are involved in management. This study intends to present a 'hair pin' case as a foreign body in the bladder.

Methodology: A 25-year-old female presented to the urology outpatient clinic in early pregnancy with a history of manually inserting hairpin into the urinary bladder through her urethra four years back. She lost to follow up during pregnancy and then presented again after C-section. A plain abdominal film of the kidneys, ureters, and bladder (KUB) confirmed the location of the hairpin and large stone around it in the urinary bladder.

Results: The patient underwent endoscopic removal of foreign body and stone. At cystoscopy urethra was normal, but in the urinary bladder, there was a hairpin with stone formation at its proximal end, and distal portion of the hairpin was embedded in the bladder neck. The hairpin was pushed back in the bladder to separate from the bladder neck, followed by stone fragmentation using a stone punch. After complete removal of stones, the hairpin was aligned in the line of the urethra and removed with the help of forceps.

Conclusion: Depending on the nature of the foreign body and available expertise, methods for removing intravesical foreign bodies are opted. Mostly endoscopic techniques are used for retrieval of intravesical foreign bodies without resorting to open surgery.

Background: The present study aimed to evaluate the level of oxidative stress by measuring the plasma concentration of oxidants in Type 2 Diabetes Mellitus (T2DM) patients with and without Polycystic Ovarian Syndrome (PCOs).

Methodology: A total of 500 diabetic patients between 25 to 45 years of age were divided into two groups; group 1 included 250 T2DM patients with PCOs, and 250 T2DM patients without PCOs were included in group 2. In addition to the demographic and clinical parameters, antioxidants include Superoxide Dismutase (SOD), Malondialdehyde (MDA), Catalase (CAT), Total antioxidant capacity analyte (TAC), and Glutathione Peroxidase (GSH) was also measured.   

Results: No significant difference in the level of antioxidants; SOD and MDA was observed between the diabetic females with and without PCOs (p>0.05). However, Glutathione Peroxidase (GSH-Px) was significantly low in T2DM patients with PCOs as compared to those without PCOs (p<0.05). Surprisingly, the mean catalase levels were significantly high among T2DM females with PCOs (3.6 ± 0 .5 U/g of Hb) than those without PCOs (3.4 ± 0.7 U/g of Hb; p<0.001).

Conclusion: It is suggested that both T2DM and PCOs are linked to a high level of oxidative stress status, but the high catalase level among diabetic PCOs females is alarming and needs to be further studied. Thus, these changes accentuate the need for lifestyle modifications.

Background: Glomerular diseases are a universal health issue, and Pakistan ranks eighth in renal disease, causing 20,000 deaths every year. Renal biopsy is a valuable diagnostic tool and provides prognostic insight and therapeutic plans. The study's objective is to determine the frequency and pattern of various glomerulopathies concerning age and gender. Methodology: A cross-sectional study was performed at the Department of Pathology, Ziauddin Medical University, and Hospital, Karachi, from 19th December 2018 to 15th April 2019. A total of 91 patients were included of either gender with a clinical history of glomerulonephritis. All biopsy samples were analyzed by using light and immunofluorescence microscopy techniques. Patient data were compiled and analyzed through SPSS version 20.0. Results: A total of 91 cases of the renal biopsy were evaluated; 51.6% of these cases were male patients. Forty-nine (53.8%) cases were reported as focal segmental glomerulosclerosis, 35(38.5%) were diagnosed with membranous glomerulonephritis, and 7(7.7%) were reported as mesangiocapillary glomerulonephritis. In membranous glomerulonephritis, 7.7% were pre-spike membranous glomerulonephritis. In the current study, 35.2% of cases showed diffuse glomerular basement membrane (GBM) thickening with spikes, and 4.4% showed GBM thickening with focal spikes on silver stain. Conclusion: Glomerular diseases are slightly more prevalent in males than females. The most commonly diagnosed primary glomerulonephritis was focal segmental glomerulosclerosis, followed by membranous glomerulonephritis.
Teoria Da Agência E Compliance
Authors: Silveira Jan
Published: April 2022

O artigo tem como elemento nuclear o estudo do conflito de agência à luz da teoria geral do Compliance. Para tanto, são abordados aspectos basilares da estruturação de mecanismos de incentivos sob o enfoque do alcance efetivo de conformidade normativa, diante de possíveis conflitos de interesses. O estudo se baseia em uma análise dedutiva de mecanismos eficientes de incentivos positivos e negativos, que possibilitam a preservação da integridade institucional. O tema demonstra elevada relevância na medida em que há uma crescente preocupação reputacional por parte das empresas, especialmente no tocante à observância de princípios éticos em sua atuação, em todos os níveis da organização (operacional, gerencial e estratégico). Nas relações de agência, o principal e o agente incorrem em custos positivos de monitoramento e vínculo (não pecuniários e pecuniários) e, em diversas ocasiões, haverá alguma divergência entre as decisões do agente e as decisões que maximizariam o interesse empresarial. Nesse cenário, a adoção de incentivos que busquem aproximar os interesses do agente e os objetivos institucionais das companhias, skin in the game, passa a ser um dos focos principais do estudo, como forma de dar maior efetividade para o programa de conformidade.
Governança Para Definição Do Score De Crédito: A Participação Social Como Instrumento De Adequação Do Sistema
Authors: Souza Maique
Published: April 2022

A adoção de sistemas de inteligência artificial para a definição do score do risco de crédito tornou-se situação cada vez mais comum. No entanto, a adoção de tais sistemas, preconiza que o sistema seja adequado à sociedade para a qual será utilizado. Dessa forma, a pesquisa reflete sobre a importância de se adotar equipes multidisciplinares para a construção de sistemas de inteligência artificial de análise de crédito a fim de prover tal adequação. O problema indagou se a adoção de profissionais de áreas diversificadas para a adequada implementação do sistema de inteligência artificial de análise de crédito, com vistas a incorporar particularidades da economia local, permitirá uma melhor adequação do risco assumido em cada operação. A investigação para responder ao problema voltou-se para situações onde a análise do risco não conseguiu captar particularidades dos mercados locais, gerando inadequação na análise do risco e expondo a instituição financeira a situações indesejadas. Como conclusão da pesquisa, observou-se que a implementação de sistemas de inteligência artificial para a análise de crédito expõe a instituição financeira a novos riscos, merecendo tal situação uma estrutura de governança apropriada e dotada de instrumentos que permitam a adequação do modelo à sociedade que busca definir o risco.
A családnévhasználat jellegzetességei a viccek szövegtípusában
Authors: Takács Judit
Published: April 2022

The study examines the characteristics, use, context, and circumstances of Hungarian surnames used in jokes from the formation of stereotypes. The paper hypothesizes that surnames are an essential element of the jokes. In fact, in these types of texts, the new meanings associated with a name allow it to move towards typical names or stereotypical use (by separating it from its original use and context). Research is based on a corpus of almost 9000 jokes and a questionnaire survey of 102 people based on the corpus. Although surnames are common in the Hungarian jokes examined, their large number and frequency do not mean they are varied. The 700 examples within the 9000-joke corpus only contain 21 different family names. An examination of the surnames and first names in the corpus confirms that more surnames that appear in jokes are primarily ethnic, while first names denote stereotypes of belonging to other groups: in jokes, the average Hungarian man is called Kovács, the typical Jewish man Kohn, and the typical Romani man is most often Kolompár. In the case of jokes featuring Hungarian and Jewish men, the surname, which is generally considered common and therefore typical of Hungarians and Jews, clarifies ethnocultural categorization and group formation. However, in jokes that feature Romani men, using an ethnic signifier or the frequent combined use of a signifier and a surname (considered as such) and a first name also reinforce stereotyping.

Published: April 2022

The study examines issues related to translating an author’s name and character names when these are considered paratexts. The introduction briefly describes the interdisciplinary context of study into paratextuality, pointing to the research areas emerging at the intersection of literary theory, translation studies, and onomastics. The paper then analyzes the translation methods used in the case of authors’ names, pseudonyms, title characters, and intertextual names in separate sections, focusing on publications of popular literature and 20th-century Hungarian prose, especially Zsigmond Móricz, Dezső Kosztolányi and Jenő Rejtő in foreign languages. Following the criteria described in the literature review, the study examines verbal paratexts and the visual paratexts of the covers (typography, cover image).
