q-Gaussians and the shapes of Raman spectral lines
Authors: Sparavigna Amelia Carolina
Published: March 2023

q-Gaussians are probability distributions having their origin in the framework of Tsallis statistics. A continuous real parameter q is characterizing them so that, in the range 1 < q < 3, the q-functions pass from the usual Gaussian form, for q close to 1, to that of a heavy tailed distribution, at q close to 3. The value q=2 corresponds to the Cauchy-Lorentzian distribution. This behavior of q-Gaussian functions could be interesting for a specific application, that regarding the analysis of Raman spectra, where Lorentzian and Gaussian profiles are the most commonly used line shapes to fit the spectral bands. Therefore, we will discuss q-Gaussians with the aim of comparing the resulting fit analysis with data available in literature. As it will be clear from the discussion, in particular referring to (Meier, 2005), this is a very sensitive issue. Then, we will consider results given in a recently proposed analysis of carbon-based materials, obtained by means of mixed Gaussian and Lorentzian line shapes, defined as GauLors (Tagliaferro et al., 2021). In this paper, we will also provide a detailed discussion about pseudo-Voigt functions. We will show a successfully comparison of q-Gaussians with pseudo-Voigt functions
BODIPY-based Fluorescent Indicators for Lipid Droplets
Authors: Zhu Jianping , Kaur Amandeep , New Elizabeth J
Published: March 2023

Lipid droplets are essential for cellular lipid storage, playing critical roles in cellular lipid metabolism. Although lipid droplets have drawn intense research in recent years, much remains to be uncovered about the roles of this organelle in biology. Lipid droplet indicators exhibiting large Stokes shifts and improved brightness are therefore in demand. We report two asymmetric BODIPY derivatives, BoL1 and BoL2 bearing a benzothiazole group at the 6-position, which led to bathochromic shifts of 62 nm for BoL1 and 37 nm for BoL2 in fluorescence emission when compared to the reference molecules without the benzothiazole group. The incorporation of the benzothiazole moiety also resulted in a large Stokes shift of 40 nm. BoL1 and BoL2 have been demonstrated to operate as lipid droplet indicators in both confocal and STED imaging. BoL2 showed particularly good cellular retention and was further applied to explore the impact of cellular starvation on the trafficking of lipid droplets.
On the Choice of Coordinate Origin in Length Gauge Optical Rotation Calculations
Authors: Parsons Taylor , Balduf Ty , Caricato Marco
Published: March 2023

In this work, we explore the issue of origin dependence in optical rotation (OR) calculations in the length dipole gauge (LG) using standard approximate methods belonging to density functional theory (DFT) and coupled cluster (CC) theory. We use the origin-invariant LG approach, LG(OI), that we recently proposed as reference for the calculations, and we study whether a proper choice of coordinate origin and molecular orientation can be made such that diagonal elements of the LG-OR tensor match those of the LG(OI) tensor. Using a numerical search algorithm, we show that multiple spatial orientations can be found where the LG and LG(OI) results match. However, a simple analytical procedure provides a spatial orientation where the origin of the coordinate system is close to the center of mass of the molecule. At the same time, we also show that putting the origin at the center of mass is not an ideal choice for every molecule (relative errors in the OR up to 70% can be obtained in out test set). Finally, we show that the choice of coordinate origin based on the analytical procedure is transferable across different methods and it is superior to putting the origin in the center of mass or center of nuclear charge. This is important because the LG(OI) approach is trivial to implement for DFT, but not necessarily for non-variational methods in the CC family. Therefore, one can determine an optimal coordinate origin at DFT level and use it for standard LG-CC response calculations.
Cumulative complexity meta-metrics as an efficiency measure and predictor of PMI during synthetic route design
Authors: Angelini Lucrezia , Coomber Charlotte , Howell Gareth , Karageorgis George , Taylor Brian
Published: March 2023

Functioning as a surrogate for step count, a cumulative complexity meta-metric, calculated along the longest linear sequence of a synthetic route, is demonstrated to be a useful predictor of process mass intensity (PMI). In contrast, common theoretical measures of efficiency such as ideality and convergence, in this case, were found to be of limited use. A workflow and model are presented which allow prediction of PMI from for small molecules (<600 Da) with good accuracy (R2 >0.9) when applied to a test dataset and a small number of literature examples. Requiring no empirical investigation, this method provides estimates of achievable, long-term PMI for synthetic routes and can be applied at the design phase. The overall procedure has been developed to be amenable to future automation, allowing rapid application across large numbers of synthetic routes.

Computer Vision as a New Paradigm for Monitoring of Solution and Solid Phase Peptide Synthesis
Authors: Yan Chunhui , Fyfe Calum , Jamieson Craig , Reid Marc
Published: March 2023

We report a strategy for the direct, non-contact colorimetric reaction monitoring of amide bond formation, mediated by coupling reagents, from video footage. For amide bond formation in solution phase, investigation of reactions mediated by HATU, PyAOP, and DIC/Oxyma revealed correlations between color parameters extracted from video data and the extent of conversion to amide product measured by off-line HPLC analysis of concentration. These correlations, supported by mutual information analysis, were further investigated using video recordings of solid phase peptide synthesis (SPPS), co-analyzed by off-line HPLC to track remaining unreacted substrate in solution. An optimization method of coupling time in SPPS was derived from E (a measurement of color contrast), giving comparable isolated peptide quality at 65 – 95% reduced overall reaction time. The same color data enabled data-rich monitoring of reaction rate attenuation, consisted with computationally-derived measures of amino acid steric bulk. These findings evidence the promise of camera technologies towards a fully automated and online mechanistic profiling of SPPS.

Authors:   Irkutsk Law Institute Affiliated to the University of Prosecutor's Office of the Russian Federation, Derevskova V. M.
Published: March 2023

The article deals with the issues of prosecutor's supervision over the production of inquest on state crimes, its evolution in comparison with the norms of the Charter of criminal proceedings and subsequent changes in 1870–1904. The author considers that the scope of powers of the prosecutor has been significantly reduced when exercising supervision over the activities of the gendarmerie conducting inquiries into state crimes. Restrictions were introduced even before the establishment of an exceptional regime in Russia and made it possible to expand the powers of the political police in the fight against the revolutionary movement.

Mining has played an important role in the development of the country in the last two decades, which is why we could call it the “mining boom”. This is confirmed with positive correlations of historical GDP data at national level and mining GDP. There is a high correlation between the regional economy and the regional mining activity (measured in terms of GDP according to regions). However, mining activity does not directly affect regional agricultural activity, agriculture continues its normal course of development. All regional GDP from 2007 to 2017 show positive growth rates. Likewise, all regions have a positive growth rate in the agricultural sector. The average annual growth rate of the mining sector at the country level from 2007 to 2017 varies by region. Some regions grow positively and others have a lower annual growth rate. In general, each of the regions is unique, presenting different growth rates in its regional GDP, agricultural GDP and mining GDP. The secondary information comes from the Central Reserve Bank of Peru, National Institute of Statistics and Information and the Ministry of Mining, among others.

Published: March 2023

The Peruvian Altiplano is frequently threatened by extreme climatic conditions, such as droughts, frosts, heavy rains, hailstorms, snowfall, etc.; situation that is aggravated by climate change. Paradoxically, the Region of Puno, which has great productive potential at the national level, presents high levels of poverty, extreme poverty, anemia and chronic malnutrition despite regional development efforts; the document analyzes and explains food insecurity in the Puno region in terms of food availability. The purpose was to estimate the caloric nutritional coverage per inhabitant and determine the percentage contribution of food groups to the availability of calories in different situations of climate change (normal, flood, drought), based on the food balance developed by FAO. The analysis revealed that the productive potential of the Puno region depends mainly on climate behavior, which makes it a high risk. The caloric nutritional coverage in the region, during a normal year, reaches only 60% of the theoretical caloric needs of one person per day, with a caloric deficit of 40%; a year with excessive rainfall generates a calorie dependence on food of 60%; while a year of drought generates 87%. The food groups that contribute most to the availability of calories are tubers, cereals and red meats. However, the proportions of the offer vary substantially according to the particular behavior of the rains. With a sensitivity analysis, it is also shown that food availability can be greatly improved, doubling the regional production of potatoes and quinoa, achieving a nutritional coverage of 95% of the nutritional requirements. These results should be considered to implement public policies focused on correcting the caloric imbalance and adaptation to climate change in the Puno region

Published: March 2023

The study area is an oil and gas field that has a low resistivity reservoir zone in the Talang AkarFormation, South Sumatera Basin. The reservoir zone is composed of siltstone and sandstone that was depositedin a shallow to transitional marine environment. The aim of this study is to identify and determine the potential oflow resistivity reservoirs in the study formation. The data used in the study include well log, mud log, core data(porosity, permeability, petrography), formation water analysis, and biostratigraphy. The methodology includesqualitative analysis to determine reservoir potential zones (quick look interpretation) and the reason for low resistivityreservoirs, as well as quantitative analysis to calculate petrophysical parameters. The results of the quicklook analysis showed 77 low resistivity reservoir zones, but the petrophysical analysis identified 25 low resistivityreservoir zones as potential candidates for drill steam test (DST). Factors causing low resistivity reservoirs inthe study area include clay mineral content (kaolinite and illite), conductive minerals (pyrite and siderite), highsalinity formation water (10,000 ppm), very fine to medium sand grain size (0.063 - 0.5 mm) distribution ofclay minerals (laminated and dispersed clay), and thin laminates. The results of the petrophysical analysis showthat shale volume is less than 30%, porosity is greater than 14%, permeability is greater than 10 mD, and watersaturation is less than 70%.
language difficulties of comprehending the text of a contract and ways to overcome them
Authors: Kozlova Marina Yu , Davydova Marina L.
Published: March 2023

In modern civil circulation, a significant number of contracts are those of adhesion. As confirmed by judicial practice, the joining side may not understand the contract’s content or have a mistaken notion about it. The aim of the article is to research the reasons and consequences of lack of language clarity on the contract’s terms for the side that joins the contract, in order to determine the ways to eliminate them. The empirical method, the methods of description and interpretation, and the theory of formal and dialectic logic are used in the article. The reason for not understanding a contract’s terms might not be the objective complexity of the text, but the fact that the contractor does not read it. A conclusion is made that juridical means of protecting a contract’s side that has concluded a contract due to wrongous influence, are not always effective. The legal and linguistic design of a contract implies using any means of visualization that lets the contractors comprehend the meaning of a contract.

Estimating effort involves figuring out how many personnel are involved in various company operations and how long it will take to complete an IOT in Machines and software development project. This estimate is crucial in order to understand how much the relevant value of the software generated. The Global Wavelet Method is a frequent technique used to determine the projected effort. The GVM approach, which Tokey[15] only relies on data from three software development projects, is the subject of this study's review. However, most academics have continued to use the proposed Estimate Rate (ER) using Tokey's value without challenging its applicability. The estimated effort calculated using the GVM approach by multiplying the GVM Value by the ER. ER Value was 40 hours for people and 90 hours for machines. The ER Value, the end outcome of this study, is equal to 6.2. This amount is considerably less than Tokey's ER Value. This is possible for a number of reasons, including the existence of software engineering methodologies, more sophisticated software engineering technology, software that is composed of individual components, and lastly the availability of source code on the internet.

Published: March 2023

Many potentially devastating earthquakes have been allowed to occur in India. The Indian subcontinent suffered a devastating earthquake. The resulting human and material costs are enormous. The Bhuj earthquake hit Gujarat around 8:40 a.m. on January 26th, 2001. A lot of things have changed after the earthquake. India’s seismic regulations. There is a great need to evaluate the seismic performance of existing RC frame buildings, many of which were designed for a different load, and to retrofit them as necessary to increase their strength against earthquake forces, given what is known about the causes of past earthquakes and the likelihood that similar events will occur in the future. As we saw in the Bhuj Earthquake of 2001, open ground storey frame structures are especially vulnerable to the destructive forces of earthquakes, making it imperative that the ground story be fortified against massive deformation. The first floor of this G+3 building in Seismic Zone 4 has been retrofitted using three different methods. Here is a list of them: jacketing for the basement’s concrete slab. Filler wall made of reinforced concrete. Iron Reinforcement. Therefore, the primary goal of this research is to determine the efficacy of various retrofitting strategies with respect to reducing seismic risk.

Published: March 2023

Background: The evaluation of patient satisfaction provides an indicator of the quality of care and contributes to strategies for the improvement of healthcare delivery. Objective: To assess patient satisfaction with services accessed under the contributory scheme at Katsina State in North-West, Nigeria. Methodology: A cross-sectional study with a sample size of 393 Katsina State Contributory Scheme (KTSCS) patients under a formal sector program was done from 1st October to 30th November 2022, at Katsina State, Nigeria. Patients were selected by multistage sampling techniques. Data was collected using a questionnaire adapted from a study by Parasuraman et al., (1988) who designed the SERVQUAL instrument to specifically measure functional service quality using both the gap concept and service quality dimensions. The SERVQUAL instrument, in its original form, contains twenty-two pairs of Likert scale statements structured around five service quality dimensions: These dimensions are: · Tangible: describes the appearance of physical facilities, personnel, and equipment. · Reliability: deals with the ability to perform the promised service dependably and accurately. · Responsiveness: considers the willingness to help customers and provide prompt service. · Assurance: talks about the knowledge and courtesy of employees and their ability to inspire trust and confidence, and · Empathy: the ability to provide caring and individualized attention to customers Results: The overall average satisfaction score was 75.8%. The study found that the positive gap of responsiveness, assurances, and empathy means that patients were satisfied with the quality of the service associated with these three dimensions, however, the negative gaps across the reliability and tangibility indicated that patients’ expectations generally were not being met. Conclusion: This study showed that the overall patients' satisfaction with services accessed was good. However, there is a need for the KTSCS and healthcare providers to continuously improve on the provision of healthcare services and address areas of dissatisfaction.

The study was conducted to investigate agricultural price transmission across space and time of cowpea in Taraba State, Nigeria. Secondary data was the main sources of data which was collected from the prominent market in the State on weekly basis for the period of 16 months (between November 2021 to February 2022). Purposive sampling technique was adopted for the selection of cowpea markets on the basis of production output and market activities. Inferential statistics were used as analytical tools which involved the use of Augmented Dickey Fuller (ADF) test, Johansen Co-integration Model, Granger Causality tests and Vector Error Correction Model (VECM). The results of the study indicates that price of cowpea in the study area were stationary at first order of difference at 5% significant level. The result of Johansen cointegration analysis was based on trace statistics, which revealed high existence of co-integration among the market pairs in the study areas. The analysis of the study reveals that there exist bidirectional and unidirectional causality between cowpea markets. The study confirms the existence long run relationship running from Sabon Kasuwan Mubi to other market and also the existence of short run relationship among the market pairs in the study area. The study concludes that there is a strong co-integration between cowpea markets in Taraba State due to efficient free flow of price signals and market information between market pairs. Cowpea markets in the research area have a long-run and short run dynamic. It is therefore, recommended that government should make market infrastructure a priority in the State by providing storage facilities and a robust transportation system.

This study provided critical examination of policy formulation and implementation of Vocational and Technical Education (VTE) in some African countries. The study brought to fore relevance of VTE in engendering peace building and socio-economic development in Africa by examining four African countries: Nigeria, Botswana, Tanzania and Algeria. Apart from Nigeria in West Africa, three other countries were randomly selected one each from South, East and North Africa respectively. Juxtaposition of the objectives of VTE in the four countries was made. The study advocated a holistic implementation of policies on VTE in the African continent. Thus, it critically examined the concepts of vocational and technical education, relationship between vocational and technical skills acquisition and peace building in Africa. It also considered the roles of VTE in socio-economic reconstruction in the continent and how VTE engenders peace among the youths. National governments of each nation should give VTE due attention that makes school children and youths acquire work-related and work-based skills which will guarantee their employability after leaving schools rather than being school leavers who lack the required employable skills in the labour market. The study concluded that if this is done, every youth will be gainfully engaged and have no time for idleness and restiveness.

In developing countries, it is not only the pandemic that is the main problem. However, difficult access to health care facilities is also a chore that has not been properly resolved by the government. In order to answer the above phenomenon, an initiative has been drawn up that leads to the development of the Pulau Tanjung Home Care Program (PHC program). Unlike home care in general, the PHC program places more emphasis on preventive action by not neglecting curative and rehabilitative. This program is structured with two main perspectives: Islamic economics approach and person-centered care. This program also has four main pillars that must be met: home-based medical check-up, home-based assessment and treatment, sustainable treatment and follow-up based on diagnosis, and health insurance for everyone. This literature review aims to develop the concept of this program so that it fits the background of the program in developing countries.

Objective: A ventricular septal defect (VSD) is defined as a communication between the left and right ventricles or between the left ventricle and the right atrium. VSDs are amongst the most common abnormalities of the heart. They can be present in isolation or in association with other congenital cardiac abnormalities. This is study done with the aim to evaluate the types, size, associated CHD with ventricular septal defect in children and adolescent in two cardiac centers (Medical City Complex cardiac clinics, Ibn Al Nafaes teaching hospital) in Baghdad - Iraq Methods: Prospective cross sectional study based on echocardiography done pediatric cardiology centers and included all children and adult (birth to 25 years old) with VSD during period from 1st of October 2021 till 1st of July 2022. The examination performed in the lateral decubitus position using the echocardiography device (GE VIVID 9), transducer M6Sc-D and M5Sc-D. All patients were examined standard transthoracic echocardiography (TTE) including two dimensional, colors Doppler and M -mode. The standard technique was used to obtain the measurements. Size and type of VSD were examined in different standards four chambers, five chambers, parasternal long and short axis and subcostal views. The sample was divided into two groups, group 1 isolated VSD; and Group 2 associated with other CHD. The data collected for patients with ventricular septal defect and the age (from birth to 25 years old).A convenient sample of 206 patients with VSD was selected from consultancy clinics and wards of selected hospitals. Results: A total of 206 patients with ventricular septal defect were included in this study; 105 patients (51%) from Medical city complex, 101 patients (49%) from Ibn Al Nafeas teaching hospital. Males were 49% while females were 51%. The prevalence of isolated VSD 99(48%) and VSD associated with other CHD 107(52%). Symptomatic VSD were 60%, while Asymptomatic VSD diagnosed incidentally were 40%. The most common type of VSD was Perimembranous 73 followed by muscular 19%, Inlet (canal type) 7% and Outlet (subarterial) Subpulmonic VSD 1% respect. The most common associated CHD was PDA 33 (30.8%), followed by ASD Secundum 30 (28%), PS 10 (9.3%), Coarctation of aorta 8 (7.4%), MR 7(6.5%), TOF 6 (5.6%), Atrioventricular canal defect 3 (2.8%), DORV 2 ( 1.8%) and each of L-TGA, DTGA, Dextrocardia , truncus arteriosus and tricuspid atrasia had 1 (1%). Conclusions: The most common VSD type of studied patients is perimembranous in followed by muscular, inlet type and the less common is outlet. Although multifactorial, Consanguinity marriage with positive family history plays a great role of recurrent CHD in families.

Alopecia areata (AA) is an auto-immune disease in which there is an inflammation around the anagen phase of hair follicles. Many nutritional elements were found to modulate this immune response. Zinc and ferritin have many vital roles inside the body and are considered among the most important nutritional factors in immune modulation and division of hair follicle matrix cells. This study aimed to investigate the role of zinc and ferritin in patients with alopecia areata. A case control study including a total of 40 patients with AA who were attending the outpatient clinic at Al-Kindy Teaching Hospital, Baghdad during the period from 2nd June 2019 to 31st March 2020. Other 65 age- and gender- matched apparently healthy subjects. Demographic of the patients and controls and clinical data of the patients were recorded through direct interview. Blood samples were collected from all participants, and serum level of zinc and ferritin were measured using enzyme linked immunosorbent assay(Elisa). Results revealed that in three-fourth of the patients, only scalp was involved in the lesion, while mixed lesion was reported in the 25% of the patients. Single and multiple lesions were reported in 42.5% and 57.5% of the patients respectively. Median serum level of ferritin in patients was 23.0 μg/L (range=3-98 μg/L) which was lower than that of controls (median = 27.0 μg/L, range= 10-166 μg/L) with a significant difference. Likewise, median serum level of zinc was 59.5 μg/dl (range= 15-175 μg/dl) in patients compared with 71.5 μg/dl (range= 21-201 μg/dl) in controls with a significant difference. Zinc level showed a significant positive correlation with age (r= 0.334, p= 0.041) and negative correlation with lesion size (r= -0.327, p= 0.045). In conclusion, multiple lesions in the scalp are the most common presentation of patients with AA. Low levels of ferritin and/or zinc could be involved in the pathogenesis of AA and increase the risk of disease severity.
