by Capillary Electrophoresis and Related Techniques with Different Chiral Selectors: A Review

ecognition mechanism and enantiomerically separations of the chiral compounds are subjects that always stimulate the great interest of researchers in pharmacology and natural sciences, who are interested in finding solutions for both analytical purity and preparative purposes. Capillary Electrophoresis has become one of the most important analytical approaches for enantiomeric separations due to its superior properties, such as high resolution and high efficiency of chiral selectors. In this field, where researchers continue to be interested, the distinctions continue to develop day by day, with the introduction of new techniques developed on the basis of Capillary Electrophoresis philosophy in parallel with the development process of technology, as well as the chiral selectors of many different forms. In this review, besides some descriptive theoretical information about capillary electrophoresis and the techniques associated with it, studies on chiral separations using different chiral selectors or different chiral additives, such as molecularly imprinted polymers, cyclodextrins, Metal-organic frameworks, ionic liquids, nanoparticles and monoliths in the last nearly 10 years (2010-2020) were examined.
Diagnosis and Management of Insulin Resistant Polycystic Ovarian Syndrome: A Simplified Review

Polycystic Ovarian Syndrome abbreviated as PCOS is one of the common leading endocrine syndromes in middle aged women. PCOS itself is a collection of metabolic risks and symptoms such as hyperandrogenism, infertility, hyperinsulinemia, dyslipidemia, ovulatory dysfunction, type 2 diabetes and endometrial cancer and increased blood pressure Some of these metabolic risks are the physiological drivers of the syndrome and one such risk is insulin resistance. Around 50-70% of the women diagnosed with PCOS are showing the symptoms of insulin resistance. Despite obesity, insulin resistance is seen in both lean and obese PCOS patients. But obesity may be part of the reason for insulin resistance in women with PCOS. Hence hyperandrogenism is more favoured in women with obesity. Although IR associated with PCOS is a common feature, dysregulation of the insulin activity is related to the pathogenesis of PCOS. This chronic condition will escort the syndrome to major metabolic disorders substantially increasing the risk for developing diabetes (prediabetes or type2 diabetes) and furthermore increased hyperandrogenism. Various tests have been developed to determine the insulin resistance like HOMA-IR, clamp techniques, glucose and insulin levels. In addition, till to date diverse advanced markers have been proposed in the scientific literature to diagnose insulin resistance, PCOS and their association. Further research into the basic fundamentals of the syndrome is necessary to manage the disorder. The purpose of this review article is to deliver the simplified view on insulin resistance PCOS for the better understanding of the etiology, symptoms, diagnosis and therapeutic management.
Traditional uses of Detarium Microcarpum Guill. & Perr. (Fabaceae) and Potential for its Valorisation as Fuelwood

Background: Forest management can be sustainable if it integrates social, cultural and economic values ​​that local communities associate with forest resources in a given area. Detarium microcarpum Guill. & Perr. (Fabaceae), also known as small detar or sweet detar, is a common multiuse small tree of Sudanese and Sudano-Guinean savannahs with high potential for use as fuelwood or fruit tree but little valued in forestry programs. The present countrywide study aims to assess the compatibility of current local uses of Detarium microcarpum with its promotion as fuelwood and to determine the most suitable areas for its integration into forest management programs. Methods: An ethnobotanical survey was conducted on the basis of a semi-structured questionnaire among 1074 people selected randomly in 10 of the 12 departments of Benin where the species is present. Factors determining Detarium microcarpum use as fuelwood were identified through a binary logistic regression. A Factorial Correspondence Analysis established the relationship between socio-cultural groups and the use of Detarium microcarpum parts or organs.Results: A total of 671 people (62.47%) know and use at least one part of Detarium microcarpum. The trunk and branches are the most used organs (35.12% of respondents), primarily as fuelwood. The determinants of Detarium microcarpum use as fuelwood are the phytogeographic district (a proxy for the resource availability), gender, sociolinguistic group, and educational level. Detarium microcarpum is more used as fuelwood by women belonging to the sociolinguistic groups Gourmatche, Kounteni, Boo, Monkole, Gando and Bariba. In addition, the use of Detarium microcarpum as fuelwood decreases with the educational level and is more pronounced in the phytogeographical districts of Borgou-Nord, Atacora chain and Borgou-Sud, covering together about 63% of the national territory and representing 28% of its population. Conclusions: This study confirms the potential of Detarium microcarpum as fuelwood, particularly in northern Benin, and calls for further research on the species local abundance and structure, regeneration, silviculture and management mode.
Emission spectra of photoionized plasmas induced by intense EUV pulses: Experimental and theoretical investigations

Experimental measurements and numerical modeling of emission spectra in photoionized plasma in the ultraviolet and visible light (UV/Vis) range for noble gases have been investigated. The photoionized plasmas were created using laser-produced plasma (LPP) extreme ultraviolet (EUV) source. The source was based on a gas puff target; irradiated with 10ns/10J/10Hz Nd:YAG laser. The EUV radiation pulses were collected and focused using grazing incidence multifoil EUV collector. The laser pulses were focused on a gas stream, injected into a vacuum chamber synchronously with the EUV pulses. Irradiation of gases resulted in a formation of low temperature photoionized plasmas emitting radiation in the UV/Vis spectral range. Atomic photoionized plasmas produced this way consisted of atomic and ionic with various ionization states. The most dominated observed spectral lines originated from radiative transitions in singly charged ions. To assist in a theoretical interpretation of the measured spectra, an atomic code .
Abundance Modification by the Diamagnetic Effect

Abundances of elements with first ionization potential (FIP) less than 10 eV in the corona and solar wind are augmented relative to the solar photosphere. This enhancement has been found to be independent of both mass and charge. We emphasize two facts that are relevant to this problem: (1) Only elements with FIP<10 eV are already ionized in the chromosphere, while in the corona, all elements are ionized. (2) It is known that diverging magnetic field structures anchored in the photosphere pass to the chromosphere (e.g., sunspots). Considering these facts, we construct a model in which the combination of the diamagnetic effect and gravity will pump charged particles, but not neutrals, from the chromosphere into the corona, thus producing the observed enhancement of low- versus high-FIP elements. This charged particle pump is operational irrespective of the existence of other mechanisms that have been proposed previously. Qualitative agreement is obtained with observed abundance ratios in the Sun and several stars.

An accurate determination of surface lignin required calculation methods incorporating lignin molecular formulae.
Chronic kidney disease progression among patients with type 2 diabetes identified in US administrative claims: a population cohort study

ABSTRACT Background Chronic kidney disease (CKD), one of the most common complications of type 2 diabetes (T2D), is associated with poor health outcomes and high healthcare expenditures. As the CKD population increases, a better understanding of the prevalence and progression of CKD is critical. However, few contemporary studies have explored the progression of CKD relative to its onset in T2D patients using established markers derived from real-world care settings. Methods This retrospective, population-based cohort study assessed CKD progression among adults with T2D and with newly recognized CKD identified from US administrative claims data between 1 January 2008 and 30 September 2018. Included were patients with T2D and laboratory evidence of CKD as indicated by the established estimated glomerular filtration rate (eGFR) and urine albumin:creatinine ratio (UACR) criteria. Disease progression was described as transitions across the eGFR- and UACR-based stages. Results A total of 65 731 and 23 035 patients with T2D contributed to the analysis of eGFR- and UACR-based CKD stage progression, respectively. CKD worsening was observed in approximately 10–17% of patients over a median follow-up of 2 years. Approximately one-third of patients experienced an increase in eGFR values or a decrease in UACR values during follow-up. Conclusions A relatively high proportion of patients were observed with disease progression over a short period of time, highlighting the need for better identification of patients at risk of rapidly progressive CKD. Future studies are needed to determine the clinical characteristics of these patients to inform earlier diagnostic and therapeutic interventions aimed at slowing disease progression.
Utilization of Used Cooking Oil and Cassava Peel as Degradable Bioplastic Film

Plastic product has become a main thing that used in human daily life. Mostly after the plastic are used, it will be a waste. Only small percentage of plastics are recycled and the rest will end up at landfills, rivers and oceans. Normally, plastics can take up to 1000 years to decompose in landfills and some will be burnt. The affect from burning the plastic waste in landfills will cause air pollution. When it burns with food waste, they will produce dioxin and furan. These elements will cause death even in small quantities when human breathe. Another harmful effect of burning plastic waste, is it can damage the ozone layer. Moreover, plastic pollution can affects all living things. At least 100 million marine mammals have died each year because of these plastic pollutions. The main objective of this research is to conduct starch extraction from cassava peels and glycerol extraction from waste cooking oil. It has been achieve during the extraction of 100g cassava peel will yield 3% of starch, while 800ml waste cooking oil yield of 5% only. The best formulation of the bioplastic obtained by controlling the ratio of carrageenan and starch at 2% and 5%. From the physical properties studies which is degradation in water and steam test. Based on the observation of degradation test, when the temperature was at 100ºC the bioplastic degrade within 1.18 minutes and at 20ºC was within 7.33 minutes. For the steam test, only at 100ºC the bioplastic start to degrade within 25minutes but for other temperature the plastic remains same. As a conclusion cassava starch can be utilized as bioplastic film, because it can dissolve when contact with water and steam. Moreover, glycerine from waste cooking oil can be used as plasticizer.
A Possible Radiation-Induced Transition from Monazite-(Ce) to Xenotime-(Y)

This study examines two pegmatitic monazite samples (2a and 4b, these numbers are related to a previous study) to determine their crystal chemistry and effects of internal radiation damage using synchrotron high-resolution powder X-ray diffraction and electron-probe micro-analysis. Both the huttonite and cheralite substitutions are discussed. Rietveld structure refinement of sample 2a shows three different phases [2a = monazite-(Ce), 2b = monazite-(Ce), and 2c = xenotime-(Y)] with distinct structural parameters. The changes among the unit-cell parameters between the two monazite-(Ce) phases is more pronounced in the a followed by the b and c unit-cell parameters. Sample 4a is a single-phase monazite-(Sm) that contains 0.164 apfu Th. Phase 2c with space group I41/amd arises from redistribution of La, Ce, Pr, Nd, Sm, Gd, Dy, Si, and Y atoms from those in monazite (space group P21/n). A possible cause for the phase transition from monazite-(Ce) to xenotime-(Y) is α-radiation events over a long geological time. However, other chemical processes cannot be ruled out as a cause for the transition.
Impact of a transdiagnostic prevention protocol for targeting adolescent anxiety and depression

The present study examined the benefit of a transdiagnostic prevention program, Super Skills for Life (SSL), among adolescents with internalizing and/or externalizing problems in two types of school settings (mainstream school and pupil referral unit) using a randomized waitlist-controlled trial (RCT). The main aims were to examine the effects of the SSL-A in reducing internalizing and externalizing problems in adolescents, and to identify the moderating role of gender, age, and school type on the intervention outcome. The RCT involved 112 adolescents aged 11 to 14 years old, randomly allocated to either an SSL intervention group or a waitlist-control group (WLC). Adolescents in the intervention group participated immediately in the SSL-A, whereas adolescents in the WLC group received the intervention after the intervention group completed the 6 months follow-up assessment. Results showed that internalizing and externalizing problems were significantly reduced from pre-test to follow-up assessments. Gender, age and school setting moderated the intervention outcome. Specifically, males, younger adolescents and adolescents from mainstream schools showed a significant reduction over time on both internalizing and externalizing problems. This study provides evidence for the benefits of a transdiagnostic prevention program for internalizing and externalizing problems in two types of school settings.
Computational study of electronic, spectroscopic and chemical properties of Cun(n=2-8) nanoclusters for CO adsorption

Int. J. Nano Dimens. , 2017; 8(2): 114-123. , DOI: 10.22034/ijnd.2017. 24951 Abstract First-principle calculations were carried out to investigate the adsorption of CO over Cun nanoclusters. The structural, spectroscopic and electronic properties like optimized geometries, HOMO (highest occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) energy levels, binding energy, adsorption energy, vibrational frequency and density of states (DOSs) of the pure Cun nanoclusters, and CunCO complexes in their ground state were thoroughly analyzed. The CO adsorbed on the Cun nanoclusters showed a stretch frequency at 1950-2052 cm-1, which was red-shifted relative to that of gas-phase CO (2143 cm-1). This red-shift was believed to arise from the charge transfer from the Cu metal d states to the CO antibonding 2π* level. The CO adsorption on the Cu nanoclusters was chemisorption in nature with the Cu–C bond length (adsorption height) in the range of 1.85-1.92 Å.
A double design-science perspective of entrepreneurship – the example of smart contracts in the insurance market

PurposeFollowing the call for strengthening the third pillar of knowledge in entrepreneurship as well as work-applied management contexts constituted by pragmatic design principles, we present a case study on an insurtech for insurance firms specialized in smart contract insurance solutions such as flight delay or ski resort insurance.Design/methodology/approachDesign science.FindingsThis not only serves as a pointer for how insurances may master their digital transformation while remaining competitive. But moreover, on the meta level, we find that the adoption of entrepreneurial design principles by the students, whose experiential project represents our case study, does not necessarily require continuous support or foundational knowledge to be delivered beforehand. However, for a deeper or more holistic assessment of the case sketched in their project, it makes sense to introduce them to newer developments such as the simple, practical framework of the Entrepreneur's Question Index.Originality/valueInnovative teaching method on innovative topics.

Summary. Background. The research provides comparative analysis of the burnout syndrome among medical students in Lithuania and Germany and determines relations between burnout and lifestyle, health complaints and seeking for psychological help. Materials and methods. The research was conducted in April 2019 using an anonymous self-administered e-based questionnaire. The sample size was 261 medical students (age mean 20,5 ± 1,8, 46 males, 215 females): 131 from Vilnius University (VU), 67 from Lithuanian University of Health Science (LSMU) and 63 from Heidelberg University (HU), Germany. The 15 items MBI-SS scale was used to identify burnout syndrome among students (Cronbach α =0,74). Emotional exhaustion (>14), cynicism (>6), and professional efficacy (<23) scores were calculated for academic burnout. The participants were also asked additional questions related to lifestyle and well-being. Descriptive statistics were analysed using MS Office Excel, SPSS and R Commander, results were statistically significant when p<0,05. Results. 51 (38,9%) VU, 25 (37,3%) LSMU and 10 (15,9%) HU students were ascertained as burnt-out (p=0,004). 76 (90,6%) respondents complained of feeling study induced mental stress (p=0,0002). Furthermore, 67 (77,9%) respondents indicated having a bad mood (p=0,043), 54 (62,7%) general weakness (p=0,024), 44 (51,1%) digestive problems (p=0,003). Sleep duration was strongly associated with burnout (p=0,002) with over half (n=51, 59,3%) of the burnout respondents sleeping <7 hours a day. 87 (33,3%) students considered consulting a psychologist, but only 24 (9,2%) reached out for help. Conclusions. More than 1/3 of medical students in the research group had signs of burnout. The highest prevalence of burnout was among VU and lowest among HU students. Burnt-out respondents complained of mental stress, weakness, bad mood, digestive problems. The university studies and the duration of sleep can impact the occurrence of burnout syndrome. Only every forth student, willing to consult a psychologist, sought assistance.
Could a virtual bowtie filter improve image quality? A breast simulation study

ABSTRACT Introduction: During CT scanning, anatomical shapes and body contours cause variation in the transmitted x-ray intensity reaching the detector. This can compromise image quality since the detector has a limited dynamic range. In principle, suitable bowtie filters can reduce transmitted X-rays through thinner parts of the body so that it is uniform at the detector surface.Aim: This study explores the possibility of using mathematical data modelling of transmission data to act as a virtual bowtie filter. The virtual filter is applied after the acquisition of projection data and can be based on body shape. In this study, the virtual bowtie filter is constructed from breast contour information and applied to transmitted x-ray beam profiles produced in egs_cbct Monte Carlo simulations.Methods and materials: The Breastsimulator software was used to generate suitable breast phantoms. Egs_cbct simulated X-ray transport through these phantoms. One simulation included a bowtie filter that accounted for breast shape as a control. Projection images were acquired over 360 degrees without the bowtie filter. We designed a bowtie filter and corrected the transmitted X-ray profiles based on its shape.Results: Image contrast indicated any improvement in image quality. Results indicated that using a virtual bowtie correction method improved image quality as well as a reduction in cupping artefacts.Conclusion: It is a useful method to improve the image quality without the need to incorporate a real bowtie filter during measurements.

Particularly in educational settings, the pyramid of learning attitude has been altered by the usage of technological tools in learning process and thus the performance of the students. However, comprehensive integration of information technology tools to enhance the learning is a deemed necessity of information age where adolescents are seemed as digital natives. Therefore, this study focused on measuring the mediating effect of information technology usage on the relationship of Academic efficacy l 10% of secondary public schools were randomly selected from four randomly selected Tehsils of Sargodha as sample; at second stage, 20% of the 10th graders were selected from each school through stratified random sampling. Data was collected through questionnaire by using quantitative survey method. Path analysis was applied to study the mediating effect of IT usage on the relationship between academic self-efficacy and academic performance. Findings revealed that academic self-efficacy exert significant positive in direct effect on the academic performance mediated through IT usage. Similarly, academic attitude also found to have significant direct and indirect effect on the academic performance. Therefore, it is suggested that teachers should integrate the technology embedded activities in their teaching.
Current status of Iraqi artisanal marine fisheries in northwest of the Arabian Gulf of Iraq

The study was conducted to analyze the fish landings from Iraqi artisanal marine fisheries, northwest Arabian Gulf from January 2017 to December 2019. The monthly data of fish landings were collected from the main landing site at Al-Fao port, south Iraq and were analyzed using descriptive statistics. A total of 35 taxa in 18 families were identified in the artisanal catches, in addition to two species of shrimps. The highest total landings were 11,944 t in 2018 and 11,305 t in 2019. The annual total landing of the marine fisheries increased by 270% during 2017-2019 as compared with the annual landing during 2008-2016. Threadfin bream contributed 14.1%, followed by river shad (11.1%) and mullets (11.1%), whereas shrimps formed 15.2% to the total catch. The overall values of biomass diversity of fish ranged from 1.82 in 2017 to 2.85 in 2018. There were 320 registered fishing boats motorized by 65 to 950 hp. Multi gears fishing were observed. The trends of the landings of all fish groups were increased substantially, except river shad, threadfin bream and shrimps. The study suggests some of the management measures must be put into place, especially for the river shad in the regions of their migration reproductive and the nursery.
