The pre-sowing treatment of scarlet sage (Salvia splendens Ker Gawl.) seeds with 4-methyl-2-piperidin1-yl-pyrimidine-5-carboxylic acid at concentrations of 0.01, 0.05, and 0.1% proved to have an obvious inhibiting effect. Prior to sowing, the seeds of Salvia splendens were soaked in a water suspension of 4-methyl-2-piperidin-1-yl-pyrimidine-5-carboxylic acid and 4-methyl-2-morpholin-4-pyrimidine-5-carboxylic acid with concentrations of 0.01%, 0.05%, and 0.1% for 18 hours. On the 42nd day of the experiment, the seedlings, having been preliminarily hardened for 12 days, were removed from the greenhouse and planted on the field. The pre-sowing treatment of Salvia splendens seeds with 4-methyl-2-morpholin-4-pyrimidine-5-carboxylic acid proved to have the inhibiting effect at concentrations of 0.01 and 0.05%. The height of the seedlings decreased by 13.3-43.7%. It was revealed that 4-methyl-2-piperidin-1-yl-pyrimidine-5-carboxylic acid at concentrations of 0.01, 0.05, and 0.1% decreased the growth of the seedlings by 30.4-43.7%, and 4-methyl-2-morpholin-4-pyrimidine-5-carboxylic acid at concentrations of 0.01 and 0.05% decreased the growth of the seedlings by 13.3-22.2%. By contrast, the effect of pyrimidinecarboxylic acids on seed germination and plant height of another annual flower – spreading marigold (Tagetes patula L.) was stimulating. It was investigated some different concentrations from 0.01 to 0.05 %. The same concentrations of identical compounds were tested, but effects from them were opposite for Tagetes patula, and Salvia splendens seedlings. Сonsequently, the species-specific effect of pyrimidinecarboxylic acids on seed germination and plant height for ornamental grasses takes place. Therefore,4-methyl-2-piperidin-1-yl-pyrimidine-5-carboxylic acid and 4-methyl-2-morpholin4-pyrimidine-5-carboxylic acid are recommended as growth retardants for Salvia splendens.

Authors: B Darshni , V Senthil Kumar
Published: May 2021

For a thin plate, if the deformation is on the order of the thickness and stay elastic, linear theory might not turn out correct results because it does not predict the in plane movement of the member. Therefore, to account for the inconsistencies of geometric nonlinearity, large deflection theory is required [1]. This report pertains to the analytical study dispensed to check the behavior of thin plate under fixed and pinned edge conditions, and for diverse thicknesses, under the small and large deflection theories. The deformation is additionally studied, supported by Von-Karman equations. Non linear analysis has been performed on FE model using the ANSYS software. The consequences of geometric nonlinearities are mentioned. Outline on conclusion of the theoretical and experimental results obtained, are compared so as to review the similarity of the modeling and theory.
Fast analysis methods to evaluate urban requalification and regeneration opportunities in widespread areas
Authors: Pezzagno Michèle , Richiedei Anna , Tira Maurizio
Published: May 2021

The success of an urban redevelopment project is often determined by the preliminary study of the site and by the knowledge thereby acquired to guide the regeneration strategies. Local administrations of small and medium-sized municipalities are unable to play a strong role in governing regeneration since Urban Plans do not include strategic analyses of the regionswide focussing on abandoned or unused areas. A clearly-oriented framework of knowledge can make it possible to regulate urban renewal more effectively and ensure a greater likelihood of successful redevelopments. The paper presents a fast method that highlights the objective limits of brownfield sites in order to better support decisions related to the Urban Plan forecasts. The method is based on four main indicators: Accessibility, Density, Functional Mix and Compactness that link a site to the context. The quali-quantitative evaluation of the indicators and their sub-components allows the establishment of the weaknesses and the strengths of the site within the urban fabric in which it is located. The method is tested by applying it to three case studies in the area of Franciacorta in the Province of Brescia.

Magnesium-based composite materials play an important role in aerospace and automobile industries because of their low density, stiffness & high speciﬁc strength. These hybrid composite materials were needed to increase the strength, surface finish, machinability, corrosion resistance, etc. To address such a problem this work has been focused on the preparation of magnesium-based metal matrix composite materials AZ91C reinforced with the B4C with two different proportions which are prepared by using the casting process. For the characterization of the prepared Mg-based MMCs, various tests like tensile test and hardness test have been performed on three model sample specimens of namely AZ91C(100%)+B4C(0%). AZ91C(98%)+B4C(2%) And AZ91C(96%)+B4C(4%). It was found that the compressive strength is and hardness is decreased due to the addition of the B4C to the matrix alloy AZ91C while tensile strength is increased. The tensile strength is increased by 15.58% with the addition of 4% B4C when compared with 2% of B4C and also hardness is increased by 31.49%. The compressive strength is decreased by 41.43% with the addition of 4% B4C when compared with 2% of B4C.
The antecedents of supply chain performance : a case of KwaZulu-Natal province, South Africa
Authors:   ,   Durban University of Technology, Mbambo Daluxolo
Published: May 2021

Over the past years, there has been a growing significance in supply chain management (SCM) as a vehicle through which many companies/firms can reach a competitive advantage. Despite the importance of supply chain within today’s economy, little is known about how SCM mechanisms can contribute to firm performance. The main purpose of this study was to evince the influence of trust on supplier development, knowledge creation and supply chain performance (SCP) in KwaZulu-Natal (KZN) Province, South Africa (SA). It was a cross-sectional study that was conducted with different samples and several variables. This is a quantitative study which used a probability and non-probability approach. The study was conducted using both the simple random technique and convenience sampling. Descriptive analysis was performed using the IBM SPSS 25 software package. A sample size of 495 respondents was used in this study. In total, 310 questionnaires were received from all respondents who participated in this study. Results specified that trust does not have any direct impact on SCP. However, based on the beta coefficient values, trust predicts better knowledge creation than supplier development. The empirical results show that an organisation/firm that has a high level of knowledge creation with its suppliers will yield greater performance within its supply chain (SC). As the supply chain performance enabled process was empirically defined, firms are therefore able to design appropriate collaborative strategies for their SC. Thus, the capability to integrate external knowledge from different sectors could be a major factor in firms’ improvement capacity. This study recommends that the South African Government must provide training for firm owners and easy funding access for SMEs in KZN to be able to confront competition from local and foreign competitors. Furthermore, this study suggests that staff development and training for public and private sector institutions as well as individual career management enhancement initiatives must be implemented. Collaboration with suppliers and other supply chain associates is strongly recommended, which should increase the chance to gain strengths, trust, knowledge creation, information sharing and technological proficiencies.

Authors: Tokhetova L.A. Akhmedova G.B. Akzhunis R.A.
Published: May 2021

Multivariate analysis of variance of quantitative and morpho-biological traits of 155 samples of barley (Hordeum vulgare L.) of different ecological and geographical origin made it possible to identify the most adaptively valuable traits, which include the germination rate under saline conditions, the total weight of 14-day-old seedlings, the number and length of seminal roots. Of the production traits, the number of grains per ear, grain weight per ear and protein content in combination with early maturity are significant. Statistical analysis of the data has shown that the studied variety samples according to the “number of grains per ear” and “grain weight per ear” traits demonstrate a consistently high positive correlation relationship, regardless of the years of study and their cultivation areas. In this regard, the “number of grains per ear” trait can be used as the main factor in increasing crop yields in adverse ecosystems of the Aral Sea region of Kazakhstan.

This article discusses the role of the personality of the teacher-psychologist in investigative actions. It should be noted that the investigative actions are different in content, for example: interrogation, experiment, search, identification, examination and others. In these investigative actions, the role of the teacher-psychologist is ambiguous and complex. During interrogation, the teacher-psychologist, with his presence, helps the child in the first place, so that he can calmly and truthfully answer the questions posed without fear and misunderstanding, and also helps the investigator, especially in cases where the questions are asked correctly. However, it seems that even when called to participate in the investigative action on the initiative of the investigator and helping him to establish psychological contact with the minor, the educational psychologist primarily shows concern for the interests of adolescents and not for the interests of the investigation. Consequently, while studying at a university, students, as future pedagogues- psychologists, need to master knowledge in the following subjects, juvenile pedagogy, juvenile psychology, etc. Also, during practical training, it is important to be able to use the knowledge gained in the above subjects.

Technical note: Accounting for snow in the estimation of root zone water storage capacity from precipitation and evapotranspiration fluxes
Authors: Dralle David N. , Hahm W. Jesse , Chadwick K. Dana , McCormick Erica , Rempe Daniella M.
Published: May 2021

Abstract. A common parameter in hydrological modeling frameworks is root zone water storage capacity (SR[L]), which mediates plant water availability during dry periods as well as the partitioning of rainfall between runoff and evapotranspiration. Recently, a simple flux-tracking-based approach was introduced to estimate the value of SR (Wang-Erlandsson et al., 2016). Here, we build upon this original method, which we argue may overestimate SR in snow-dominated catchments due to snow melt and evaporation processes. We propose a simple extension to the method presented by Wang-Erlandsson et al. (2016) and show that the approach provides a lower estimate of SR in snow-dominated watersheds. This SR dataset is available at a 1 km resolution for the continental USA, along with the full analysis code, on the Google Colab and Earth Engine platforms. We highlight differences between the original and new methods across the rain–snow transition in the Southern Sierra Nevada, California, USA. As climate warms and precipitation increasingly arrives as rain instead of snow, the subsurface may be an increasingly important reservoir for storing plant-available water between wet and dry seasons; therefore, improved estimates of SR will better clarify the future role of the subsurface as a storage reservoir that can sustain forests during seasonal dry periods and episodic drought.
The Lindbladian Form And The Reincarnation of Felix Bloch's Generalized Theory of Relaxation
Authors: Barbara Thomas Michael
Published: May 2021

Abstract. The relationship between the classic magnetic resonance density matrix relaxation theories of Bloch and Hubbard, and the modern Lindbladian master equation methods are explored. These classic theories are in full agreement with the latest results obtained by the modern methods. A careful scrutiny shows that this also holds true for Redfield’s later treatment, offered in 1965. The early contributions of Bloch and Hubbard to rotating frame relaxation theory are also highlighted. Taken together, these seminal efforts of Bloch and Hubbard can enjoy a new birth of contemporary relevance in magnetic resonance.

Perovskite solar cells are emerging photovoltaic devices with PCE of above 25%. Perovskite are suitable light absorber materials in solar cells with excellent properties like appropriate band gap energy, long carrier lifetime and diffusion length, and high extinction coefficient. Simulation study is an important technique to understand working mechanisms of perovskites solar cells. The study would help develop efficient, stable PSCs experimentally. In this study, modeling of perovskite solar cell was carried out through Setfos software. The optimization of different parameters of layer structure of solar cell would help to achieve maximum light absorption in the perovskite layer of solar cell. Simulation study is based drift-diffusion model to study the different parameters of perovskite solar cell. Hysteresis is one of the factors in the perovskite solar cell which may influence the device performance. The measurement of abnormal hysteresis can be done by current-voltage curve during backward scan during simulation study. In backward scan, the measurement starts from biasing voltage higher than open circuit voltage and sweep to voltage below zero. The numerical simulation used to study the various parameters like open circuit voltage, short circuit current, fill factor, power conversion efficiency and hysteresis. The simulation results would help to understand the photophysics of solar cell physics which would help to fabricate highly efficient and stable perovskite solar cells experimentally.

Authors: Swami Monika , Patel Kinjal
Published: May 2021

Gallium is an vital rare metal mainly because of its growing demand in different domain of life. It has wide applications. Gallium is considered as the backbone of the electronics industry. The supply and demand of gallium-bearing products has gradually increased during the past decade. Therefore, from the environmental stand point the need for sensitive and reliable methods for determining trace concentrations of gallium has become apparent in various fields. Gallium has become increasingly popular as a substrate material for electronic devices. Aside from ore, gallium can be obtained from such industrial sources as the Bayer process caustic liquor that is a byproduct of bauxite processing, flue dust removed from the fume-collection system in plants that produce aluminum by the electrolytic process, zinc refinery residues, gallium scrap materials, and coal fly ash. The purification process for gallium can start with solvent-extraction processes where the concentrations of impurities, especially metals, are reduced to the ppm range. The main aim of this paper is to simply put up the salient facts regarding gallium and identify applicable sources of information thereby one may create a suitable environment for the development of methods for the production of gallium via leaching through various waste samples.

Published: May 2021

In this study we investigated the in vivo Hepatoprotective activity of ethanolic extract of Garuga pinnata (EEGP) leaves in Carbon tetrachloride (CCl4) induced hepatotoxicity using wistar rats of either sex as model. Hepatotoxicity was induced by the administration of CCl4 intraperitoneally (0.125ml CCl4 in liquid paraffin (1:1) per 100g body weight). Garuga pinnata leaves extract at different dose levels (200 and 400mg/kg, p.o.) showed the dose dependant hepatoprotective effect and was compared with well known standard hepatoprotective Silymarain (100mg/kg). When groups were treated with CCl4, significant increase in serum biochemical parameters such as Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transaminase (SGPT), Alkaline phosphate (ALP), Acid Phosphate (ACP), Creatinine and alteration of tissue biochemical parameters such as reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), lipid peroxidation (LPO), and the total proteins were observed. The histopathological examination of the CCl4 treated groups showed sinusoidal congestion, centrilobular necrosis, marked vacuolations and congestion. However, pretreatment with extract of leaves of Garuga pinnata significantly reduced the increased serum levels of biochemical parameters and restored antioxidant defense enzymes level to its normal. Moreover, histopathology of leaves extract treated groups showed normal architecture with minimal sinusoidal congestion. Taken together, our study concludes that EEGP to be a more potential agent for caring liver from CCl4 induced damage.

Authors: Nurfirda Nurfirda , Kristina Susi Ari , Hanifah Suci
Published: May 2021

Background: Starting from 2019, the government has been aiming to increase the immunization coverage by up to 93%. Community pharmacists are well-positioned to extend access to immunizations by providing immunization services to patients. This objective of this study was to determine community pharmacists' attitudes and knowledge on providing immunizations including perceived barriers to immunizing. Methods: This study was a cross-sectional survey conducted in the community pharmacies in Yogyakarta province, between August to October 2019. A pre-validated questionnaire was used and piloted to a small group of pharmaciets. A convenience sampling was chosen and written informed consent was required. The questionnaire included demographic characteristics of participating pharmacists’, their readiness to provide immunization, and the barriers that may potentially happen when community pharmacists’ implement immunization services. Descriptive statistics were used to present the received data. Result: Among 120 respondents, mostly female (80.83%) and pharmacists degree as education (81.67%). Additionally, to the easiness of accessibility, community pharmacists believed that they will have a powerful role in increasing the rate of immunization and improving the vaccination service. More than half of respondents (54.17%) did not fully have good knowledge of all aspect of vaccine administration. Several barriers have been identified as the factors that can contribute to the immunization services by pharmacists. The largest barrier is the lack of regulation governing immunization by pharmacists (95.83%). Followed by a lack of competency (70.83%), lack of skills training (66.67%), lack of equipment (63.3%), and high workload on conventional services (54.17%). Conclusion: Community pharmacists have a good perception of providing immunization services but the lack of regulation, competency, and skills training becomes a barrier in providing immunization services.

Inqlab) in naturally salt-affected soil (pH = 8.79; ECe = 6.46; Sandy loam). A significant difference was observed in wheat grain and straw yield with the application of different N sources. Maximum wheat grain and straw yields (3203 and 3489 kg/ha, respectively) were recorded when ammonium sulphate was applied. Various N sources followed the order: Ammonium sulphate > urea > calcium ammonium nitrate and/or nitrophos. Comparatively higher N uptake by wheat (117.26 and 114.00 kg/ha) was observed with Ammonium sulphate and urea application, respectively. Similarly, maximum N recovery was observed with both these N sources followed by nitrophos, and calcium ammonium nitrate. However, the highest physiological efficiency (14.29 kg/kg fertilizer applied) was noted with the application of ammonium sulphate.
Dibutyl Phthalate an Emerging Contaminant in Water-Based Paints
Authors: Idayat Apanpa-Qasim Ajoke Fehintola

Seven different manufacturers of paints were purchased from two major cities in southwest Nigeria. At least one sample from the same manufacturer and colour, was identified and analyzed for dibutyl phthalate (DBP). GC/MS method was developed for the identification and quantification of dibutyl phthalate in water-based paints after solvent extraction. The highest level of DBP found was 47,100 ppb (unregistered manufacturer), followed by 45,100 and 19,400 in a white, pink and cream coloured paint, respectively, while the lowest concentration was 721 ppb in a cream coloured paints, unregistered manufacturer. The PCA results were in good accordance with the findings of the correlation coefficient. DBP is used by all manufacturers for flexibility and better spreadability. It is a cheap alternative and readily available. It's an emerging contaminant newly reported in paints and its toxicological effects should not be underestimated, since there is no regulation in place.
How the Heart Grows: From Multi-scale Data to a Multi-scale Model
Authors: Ebrahimi Nazanin
Published: May 2021

The heart is the first organ to form and the first to function during early development. Embryological heart development consists of a series of events believed to be highly conserved in vertebrates. Heart development begins with establishing the cardiac fields followed by a cardiac crescent formation at the embryonic midline. Fusion of the cardiac crescent results in linear heart tube formation. The straight heart tube then undergoes bending, elongation, twisting, and helical torsion to form a looped heart. The looping phase is then followed by septation and valve formation giving rise to a four-chambered heart in avians and mammals.
The looping phase plays a central role in heart development. Successful looping is essential for proper alignment of the future cardiac chambers and tracts. Since aberrant looping results in various congenital heart diseases, cardiac looping has been studied for several decades by various disciplines. However, looping is a very complex process and, despite a great deal of experimental data and research, the underlying mechanisms controlling the looping phase are unclear. Although several hypotheses have been proposed for the looping process, none of them has yet been fully accepted or rejected.
In this study, comprehensive experimental and computational workflows are successfully developed to investigate C-looping (the first phase of the entire looping process) using multi-scale and multi-disciplinary approaches.
Overall, our results support the differential growth hypothesis of C-looping by providing further qualitative and quantitative evidence, also provide insights into new cellular features concerning the mechanism of C-looping. This study reveals the differential patterns of growth at both the cellular and tissue levels with a high spatial and temporal resolution, and shows how geometrical changes of C-looping at the tissue level are linked to growth features at the cellular level. The developed workflow also provides a sound basis for further investigation into new research questions regarding C-looping. Furthermore, we provide the first 3D datasets for the C-looping heart with cell to organism level information, including datasets of heart images and segmented myocardial cells within the heart.

Plants have always been an indispensable part of human life since the beginning of human civilisation. Withania somnifera (L.) DUNAL, popularly known as Wintercherry or Indian Ginseng, is widely considered as Ashwagandha. In Ayurveda, it is classified as a Rasayana (rejuvenation) and projected to promote mental and physical health, rejuvenate the body in debilitated conditions and increase longevity. Due to its beneficial chemical constituents, the herb possesses a broad spectrum of biological activities and is used to treat a variety of diseases affecting human health. These include Cardioprotective activity, Anti-cancer activity, Immunomodulatory activity, Neuroprotective activity, Antimicrobial activity, Anti-stress activity,Anti-diabetic activity and Anti-inflammatory activity. The present review discusses the pharmacological importance of Withania somnifera and its important constituents.

Published: May 2021

Understanding the standing point of biodiversity is an integral part of studying habitat ecology in the arena of the applied ecology and conservation biology. Considering this, a study was conducted to understand the biodiversity of the single species, i.e. Lepidoptera in four different sites of Kota district. Four distinct habitat fragmentation sites, Chambal Garden, Ganesh Udhyan, Industrial Area and agriculture land were selected to understand the diversity and distribution of lepidopteran butterfly. As this group of butterfly is considered as “umbrella taxa”, detailed study of its assemblages could be directly correlated with the changes in microclimates in the selected regions. Therefore, diversity of the Lepidoptera was calculated by Simpson’s index of diversity and Shannon-Weiner Index. Among these four areas, Chambal Garden and Ganesh Udhyan are dominated with the Lepidoptera whereas, decline in abundance could be observed remaining two areas. This study indicated a rich and diverse butterfly habitat in the selected survey area, which could be served a s a future referral for measuring and monitoring biological diversity.

Surgery remains the best treatment for deep endometriosis. The surgical technique is essential to adequately manage the disease; however, the technique is rarely taught and reported in detail. Laparoscopic cystectomy for the treatment of ovarian endometrioma has been classically reported as a simple stripping technique; however, a meticulous technique appears to be necessary to adequately manage ovarian endometriomas, based on the natural history of the cyst. This paper reports in detail our current technique for laparoscopic cystectomy for ovarian endometrioma and all the tricks to permit reproduction, and even improvement of the technique by other surgeons.

Catamenial pneumothorax is a rare complication of endometriosis. Although fatal, no long-term therapies have been revealed to be efficacious in preventing this disorder. This report discusses two cases of catamenial pneumothorax managed with norethindrone acetate over an extended period of time. The patients responded well without recurrence of pneumothorax during treatment. While current therapies are generally used for a six month to one year period, we present a long-term, highly efficacious, and inexpensive treatment for catamenial pneumothorax in patients with endometriosis.

Brazilian cattle production is mainly conducted with the use of cultivated or native forages, which is considered one of the most efficient ways of production. In this sense, this study aimed to evaluate the production and water-use efficiency of Guinea grass under different associations between nitrogen and boron doses, as well as different regrowth cycles. The experiment field (22°42’14.6’’ S, 47°37’24.1’’ W, and 569-m altitude) has a regional climate classified as Cwa, which stands for a humid subtropical climate. The experimental design was randomized blocks, with a 4×4×11 factorial arrangement consisting of boron (0, 0.181, and 0.363 kg ha−1 cycle−1) and nitrogen (22.7, 45.5, 68.2, and 90.9 kg ha−1 cycle−1) fertilizations, plus 11 regrowth cycles and 4 replications. The pasture of Mombaça “Guinea grass” (Megathyrsus Maximus Syn. Panicum Maximum) was irrigated by a sprinkler system. Unlike boron, nitrogen positively influenced forage production. The cycles had a strong influence on production, with winter cycles being the least productive compared to the others.
