Authors: Гринин В. П. , Тамбовцева Л. В. , Барсунова О. Ю. , Шаховской Д. Н.
Published: June 2023

Звезда CQ Tau принадлежит семейству молодых звезд типа UX Ori и характеризуется очень сложным фотометрическим поведением и сложной структурой околозвездного окружения. В нашей статье на основе опубликованных фотометрических наблюдений построена кривая блеска этой звезды продолжительностью 125 лет. Из нее следует, что в изменениях блеска звезды кроме случайной составляющей, характерной для звезд типа UX Ori, присутствует также большая по амплитуде периодическая компонента с периодом 10 лет. Ее существование было заподозрено ранее. Новые наблюдения подтверждают ее реальность. Это указывает на существование в окрестности звезды второго компонента. Потоки вещества и волны плотности, вызванные движением компаньона, приводят к периодическим изменениям околозвездной экстинкции и блеска звезды. Этот результат обсуждается в контексте недавних наблюдений CQ Tau с высоким угловым разрешением.
The star CQ Tau belongs to the UX Ori type star family. It has the very complex photometric behavior and complex structure of circumstellar environment. In this paper we constructed the historical 125 years light curve of this star on the base of the published photometric observations. It shows that besides a random component characteristic of UX Ori type stars, the large amplitude periodic component with the 10 year period is also present. Its existence was suspected earlier, and new observations support its reality. It points to an existence of the second component close to the star. The density waves and matter flows caused by the companion motion lead to periodic changes in the circumstellar extinction and brightness of the star. This result is discussed in context of the recent observations of CQ Tau with high angular resolution.

Published: June 2023

Background: Caffeine boosts metabolism and the neurological system. When extreme weakness or sleepiness occurs, it is used recreationally and medicinally to reduce physical and mental fatigue. Caffeine initially stimulates the central nervous system, increasing intellect, speed, accuracy, focus, and coordination. Objective: To evaluate how caffeine nanoparticles affect potassium, calcium, zinc, and magnesium levels, in addition, the anti-bacterial activity of the samples has been employed. Methods: Eighteen male albino rats were divided into three separate groups. The first group (G1) was made up of six animals that served as a control group. The second group (G2) was made up of six animals that were given caffeine, and the third group (G3) was made up of six animals that were given silver nanoparticles from a caffeine solution. The particle size and structural morphology of Caffeine and silver nanoparticles were analyzed using Brookhaven Instruments Corp., XRD and SEM respectively. Results: The structural results showed after addition, caffeine was tube-shaped and silver was spherical granular. Caffeine has more silver nanoparticles than caffeine solution. Caffeine solution affects potassium, calcium, zinc, and magnesium levels. Additionally, the solution has antibacterial activity against the following bacteria: Staphylococcus aureus (Gram +ve), E. coli (Gram –ve), and Pseudomonas aeruginosa (Gram-ve), but it has no effect against yeast (Candida albicans). Conclusions: To determine the biological effects of caffeine-synthesized Ag NPs on zinc, magnesium, calcium, and potassium levels in male albino mice's serum, this is antibacterial against staphylococcus.
Knowledge, attitude, and practice of rational use of medicines among junior residents in a tertiary care hospital - a cross-sectional study
Authors: S Mohan , S Kishore , H Hemanth
Published: June 2023

Background: The need for rational use of medicines aims at prescribing medications to patients with doses for a period of time that is adequate and appropriately meets their clinical and individual requirements without financially burdening both the patient and community.

Aims and Objectives: The aims and objectives of the study are to assess knowledge, attitude, and practice of rational use of medicines.

Materials and Methods: After obtaining ethical committee clearance, this cross-sectional, questionnaire-based study was conducted among junior residents of KR hospital, a tertiary care hospital attached to MMC&RI, Mysore. A self-developed, pre-validated, semi-structured questionnaire was used. It was designed in such a manner to obtain information about the knowledge, attitude, and practice of rational use of medicine.

Results: The majority of the respondents were aware about parts of prescription (87%), though 61% of respondents were aware of p-drug, only 22% of them were aware of Safety, Tolerability, Efficacy, Price criteria for selection of p-drug, many were not aware about the advantages of using p-drug (71%). 10% never consider the cost of drugs before prescribing, only <1% respondents handwriting was not legible in their prescription, 40% of them never use abbreviations.

Conclusion: Teaching of rational use of medicines is not given much importance in most of the medical colleges. Continued emphasis on the inclusion of essential medicine concept in undergraduate and post-graduate medical curriculum will help in using a drug rationally.

Authors: Chakrabarty Sebanti , Ghosh Bithika , Chaudhuri Arghya , Choudhury Jayati , Bhattacharjee Debojyoti , Mukhopadhyay Mousumi
Published: June 2023

Background: Cirrhosis, a major and life-threatening complication of liver disease, has claimed over a million lives since 2010. It has been estimated that liver disease causes 1.03 million deaths/year globally. Chronic liver disease (CLD) affects metabolism of other organs such as the bone. The prevalence rates of hepatic osteodystrophy range from 13% to 70% in Western countries. Even higher prevalence rate between 68% and 95% has been reported from India. Reports from previous studies regarding the serum concentrations of 25(OH)D and its correlation with the progression of liver diseases have been inconsistent. Some studies have found that 25(OH)D levels decline as the liver disease progresses, whereas others found no significant difference between cirrhotic patients and non-cirrhotic patients or among the Child-Pugh groups. Vitamin D estimation is also thought to bear little predictive value to assess the progression of liver disease in etiologies such as hepatitis C. There are very few studies in the Eastern part of India to show the effect of CLD on bone mineral homeostasis. Based on this background, this study has been designed to reveal the effects of CLD and its severity on various parameters of bone mineral metabolism.

Aim and Objectives: The aim of the study was to evaluate the effects of different stages of CLD on bone mineral metabolism and its homeostasis.

Materials and Methods: After obtaining proper permission from the Institutional Ethics Committee, the cross-sectional study was conducted in the Department of Biochemistry in collaboration with the Department of Medicine in a tertiary care hospital in Kolkata. The study included 90 cases with established CLD and 90 age- and sex-matched controls screened from the Department of Medicine. Serum Calcium, Inorganic phosphate, 25(OH) Vitamin D, and intact parathyroid hormone (iPTH) were estimated in the Department of Biochemistry. The Child-Pugh-Tucotte score was used to grade the severity of disease.

Results: It was observed that serum calcium and serum 25(OH) D levels were significantly lower in patients with CLD (P <0.0001). Serum iPTH levels were significantly higher in patients with CLD compared to controls (P < 0.0001).

Conclusion: Routine serial estimation of serum calcium, inorganic phosphate, and 25(OH)D should be mandatory in patients of CLD so that adequate replacements can be initiated as a therapeutic adjunct.

Published: June 2023

Background: Canalicular laceration, which is commonly regarded as an ocular emergency, is caused by trauma on the eyelids and in the periorbital area. Unrepaired tears or either repair without a stent can lead to watering, strictures, and disfigurement.

Aims and Objectives: To find out common causes of canalicular tears, the extent of damage, and also to check the patency of the canalicular pathway. The primary goal of this study was to investigate the role of a stent in canaliculi laceration repair.

Materials and Methods: A study of 25 patients with diagnosed canalicular tears was done. The study duration was 28 months. After diagnosing the canalicular tear and the extent of damage associated with it, patients were operated on with a minimonaka stent with lid tear repair. Post-treatment patients were assessed periodically for 6 months to check the canalicular patency.

Results: Canaliculi tear repair using a monocanalicular stent gives acceptable outcomes.

Conclusion: Microscopic canalicular reconstruction with a Mini-Monoka tube is a safe, reliable, and simple technique, and it results in excellent anatomical and functional outcomes.

Published: June 2023

Background: Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of prostate resulting in urinary obstruction, along with irritant urinary tract symptoms. The present pharmacological management of above condition although successful has some limitations due to adverse effects of drugs.

Aims and Objectives: Phytotherapeutic agents are used in different countries for treatment of BPH. In this study, attempts have been made to find out the effect of bark extract of Prunus domestica in testosterone induced benign hyperplasia of prostate in Wistar albino rats.

Materials and Methods: Animals were divided into different groups, each containing six animals. Group I (control) received Arachis oil S/C for 21 days followed by distilled water orally for another 21 days. Group II animals were treated with testosterone (2 mg/kg) S/C for 21 days followed by distilled water orally for another 21 days (positive control). Group III (standard treatment group) was given testosterone (2 mg/kg) S/C for 21 days followed by Finasteride (1 mg/kg) orally for another 21 days. Group IV and Group V animals were treated with testosterone (2 mg/kg) S/C for 21 days followed by aqueous extract of bark of P. domestica (200 and 400 mg/kg) orally for another 21 days. After the 21st day of treatment, blood collection was done from retro orbital plexus by applying light ether anesthesia. Finally the animals were sacrificed and prostate glands were dissected and weighed. The parameters such as physical (body weight, prostate weight, and prostatic index [PI]), biochemical (Serum testosterone and Serum prostatic acid phosphatase), and histopathological study were done. Results were evaluated by One-way ANOVA followed by post hoc Tukey’s multiple comparison test.

Results: Administration of P. domestica bark extract reduced the size of prostate and the PI significantly (P < 0.001) when compared to positive control. The histopathological examination showed mild glandular proliferation with normal epithelial and stromal component as compared to positive control group.

Conclusion: P. domestica extract can be an alternative to conventional drugs for management of BHP. Further detail study with active principles is required to assess the detail mechanism of action.

Many obese people take dietary and herbal supplements to reduce weight, and millions of dollars are spent on these products each year. The efficiency and safety of several supplements, however, remain under doubt. Supplements are thought to facilitate weight reduction by increasing energy expenditure, satiety, and fat oxidation, inhibiting dietary fat absorption, modulating carbohydrate metabolism, elevating fat excretion, boosting water excretion, and improving mood. Due to the area’s rapid development, this study provides an overview of the current research on a few dietary supplements, herbal combinations, and combination products. Further study is necessary to determine the effectiveness of several supplements because they have not been put to the test in randomized controlled trials. Patients should be guided through the use of dietary supplements by nutritionists and medical professionals, who should also report any unfavorable side effects to the FDA. The production, sale, and marketing of these supplements would be subject to additional regulations.

Introdução: O príon é definido como proteína infecciosa. A PrPSc (Prion Protein Scrapie), isoforma mal dobrada da célula proteica priônica (PrPC), representa a marca patogenética de distúrbios priônicos. A descoberta de que outras proteínas, caracterizadas por desdobramento e agregação errôneas, espalham-se entre células, símile ao PrPSc, aumentou o interesse em doenças priônicas. Objetivos: Avaliar as influências genéticas no desenvolvimento e manejo de prionopatias. Métodos: Trata-se de revisão sistemática no PubMed. Foram utilizados os seguintes descritores: "prion diseases AND genetics”, com os filtros: “full text, 5 years e humans” “child: birth-18 years”. Excluiu-se artigos por não tratarem do tema e foram incluídos 11 artigos. Resultados: Estima-se em 15% a herdabilidade de prionopatias, a qual se liga a 63 mutações do gene PRNP, como variante V210I. Pacientes com doença de Creutzfeldt-Jakob (DCJ), síndrome de Gerstmann-Sträussler-Scheinker (GSS) e insônia familiar fatal (IFF) mostraram menor concentração de complemento no LCR, sugerindo estado silencioso do sistema imune inato. Para mutação V180I, validaram-se 29 variantes, sendo 4 missense e 6 relacionados a distúrbios neurodegenerativos. Notaram-se diferenças proteômicas entre subtipos MM1 e VV2 da DCJ, como mudanças do ciclo celular, da expressão gênica e estresse oxidativo, com destaque a diidrolipoil desidrogenase e genótipo PrP do códon 129. Noutro estudo, a expressão de proteínas envolvidas na via do ciclo da vesícula sináptica contrariamente aumentou e sugeriu que vesículas revestidas de clatrina se envolvam na gênese priônica. Achados de glicoformas únicas e príon resistente à proteinase K revelaram distribuição celular em mosaico. Análise proteômica da nitrosilação global de S mostrou substituição de valina por glicina no códon 114 do PRNP, relacionada a DCJ e IFF, apresentando interação com receptor extracelular da matriz entre vias mais afetadas. Observaram-se associações de tremor epizoótico com DCJ esporádica e mutação truncadora Y226X com prionopatia variavelmente sensível à protease, GSS e angiopatia amiloide PrP-cerebral. Conclusão: Há pequena proporção de prionopatias herdadas, ligadas a diferentes mutações no PRNP, com variantes nonsense ou missense de alta penetrância, de processamento local, substituições, deleções ou inserções, que podem auxiliar no diagnóstico e no manejo, necessariamente multidisciplinar, de paciente e familiares.
Il Ruolo Delle Crisi Nella Produzione, Distruzione E Ristrutturazione Degli Spazi Turistici. Il Caso Delle Isole Baleari
Authors: Isabella Luna
Published: June 2023

Lo scoppio della Grande Crisi nel 2008 ha risvegliato l'interesse per il ruolo della crisi all'interno delle scienze sociali. Tuttavia, in linea di massima, gli studi turistici hanno prestato ben poca attenzione ai momenti di crisi. Nel caso delle Isole Baleari, mentre ci sono lavori importanti sull'evoluzione storica dello spazio turistico, quelli tendono a considerare le crisi come momenti vuoti. Per questo motivo, questo articolo si concentra sul ruolo svolto dalle crisi nella produzione dello spazio delle Baleari, analizzando sia i momenti di distruzione che di ristrutturazione dell'economia politica. Dalla comprensione delle diverse crisi, dalla guerra civile ad oggi, possiamo concludere che i boom delle Isole Baleari sono il frutto indiscutibile di quelle crisi.

Published: June 2023

Se analiza el grado de aplicación del estándar RDA (Resource Description and Access) en las Bibliotecas Públicas del Estado españolas. Para ello, se procede a la elaboración de una encuesta tomando como escenario tres posibles casuísticas: que estas bibliotecas ya hayan implementado el código anglosajón; que hayan desechado la opción de aplicarlo; o que aún no hayan tomado una decisión al respecto. De las 53 bibliotecas a las que se remitió el cuestionario, se ha recabado respuesta de 28, lo que supone un 52,83 % de participación, considerándose este un dato lo suficientemente representativo para extraer resultados concluyentes. De estas 28 bibliotecas, solamente 3 –apenas el 10,7 %–, han decidido implantar RDA; 2 centros –el 7,1 %– han elegido no hacerlo; frente a las 23 bibliotecas –el 82,1 %– que aún no han tomado una decisión. Se concluye señalando la problemática e inconvenientes que la aplicación de este nuevo código catalográfico acarrea para este tipo de instituciones.

Impact of land use land cover change on the land surface temperature: A case study of Shillong
Authors: Nongpiur Mebankerlang
Published: June 2023

Shillong has been experiencing changes in land use land cover over the past years especially in the town areas where a lot of built-ups are emerging. In response to this, there has been some impacts in the distribution of temperature. In this study, remote sensing techniques have been used. The maximum likelihood method has been used for supervised classification of land use land cover from false color composite images. Landsat 5 TM and Landsat 8 OLI/ TIRS has been used in this study. The study period is 30 years from 1992 - 2022 with an interval of 15 years. The emergence and increase of more built-up and impervious land cover type surfaces has made the land surface temperature to increase. The correlation between NDVI and LST shows a negative relationship while that of NDBI and LST shows a positive relationship. The temperature has been increasing with an average of 2° C each interval of study. The hotspot analysis has been used to demarcate the heat zones. The highest temperature is found in the crowded and high built-up areas while the lowest temperature is found in the vegetated lands which further cause heat island effect in these highly built-up areas. Key Words: Land use land cover, Land surface temperature, Change detection, Hotspot analysis, Correlation analysis, Heat-island effect.
Plant Disease Detection Using Image Processing and Deep Learning
Authors: Bhaskar Deekshit
Published: June 2023

Plants play a vital role in the survival of all organisms on Earth. Due to this fact, it is very important to ensure that measures are taken to detect and mitigate any diseases on plants. Identification of the plant diseases is important in order to prevent the losses within the yield. It's terribly troublesome to observe the plant diseases manually. It needs a tremendous quantity of labour, expertise within the plant diseases, and conjointly need the excessive time interval. Hence, with the advancement in deep learning and computer vision it is now possible to detect the plant disease effectively by observing the disease pattern of leaves of plants, which will help the farmers to classify the disease in their plant. Moreover, several performance metrics are also used for the evaluation of this project. This study provides an efficient solution for detecting multiple diseases in many plant families. In this study thousands of images of healthy and infected plant leaves which are available in public domain were used to train deep learning model, which can classify the respected disease. This model has achieved a high level of accuracy in detecting and recognizing the plant variety and the type of diseases the plan was infected with.

Published: June 2023

The effect of variations in temperature and roasting time on the physical properties of coffee beans originating from the Gayo highlands with Arabica and Robusta types have been studied in this paper. Physical properties measured include weight loss, true density, porosity, and water content. The measurement procedure follows Standard Nasional Indonesia (SNI) 01-2907-2008. Three roasting levels were used in this study, i.e., Light Roast (159 -164 °C), Medium Roast (211 - 215 °C), and Dark Roast (above 232 °C) by an oven. The result showed that the weight loss for Arabica and Robusta coffee beans is from 11 - 19% and 14 - 29%, respectively. The true density for Arabica and Robusta coffee beans ranged from 0.905 - 1.085 g/cm3 and 0.950 - 1.156 g/cm3, respectively. The difference in porosity changes before and after roasting was 23 - 73% for Arabica and 33 - 68% for Robusta coffee beans. Meanwhile, the water content of Arabica and Robusta coffee beans after roasting is 0.7 - 5% and 0.6 - 6%, respectively. The value of the weight loss, true density, and water content of Arabica is lower than that of the Robusta coffee bean, while the porosity value of Arabica is higher than that of the Robusta coffee bean.

One of the limiting conditions for shallot plants to grow optimally is dry land conditions. Indigenous AMF application is one way to overcome this condition. This study aimed to determine the effect of indigenous AMF application on the morpho-physiological characters of two shallot varieties which are sensitive and tolerant to drought stress conditions. The study was carried out for 6 months on a wirehouse and laboratory scale. The Experiment used a completely randomized design with two factors. The first factor was varieties of shallots, i.e. Brebes (Sensitive) and Kuning (Tolerant) varieties of shallots. The second factor was the application of indigenous AMF which consisted of 5 levels i.e. Glomus sp1, Glomus sp2, Glomus sp3, a mixed those three isolates and control treatment (without application of AMF). The morpho-physiological observation parameters included header dry weight, root weight, and leaf proline content. From the observations, it can be concluded that under stressed conditions, the leaf proline content of the sensitive variety accumulated higher in the header than the tolerant variety, because the tolerant variety was better able to produce higher root and header weights when adapting than the sensitive. AMF inoculation did not show significant differences with the treatment without AMF inoculation on leaf proline. However, there was a tendency that inoculation of a mix of AMF isolates (Glomus sp1+Glomus sp2+ Glomus sp3) decrease the proline content in the leaves, both in sensitive and tolerant varieties so that plants are more resistant to drought stress.

In various efforts to improve the economy of the Indonesian people, the role of MSME actors is considered very important to support and sustain people's lives. Many sectors have succeeded in encouraging the government to build structure and development in improving the Indonesian economy by providing employment and fully supporting MSME actors to further develop. The position of MSMEs itself is very undoubted because they managed to survive and become the driving force of the Indonesian economy during the crisis some time ago. Likewise, the influence of globalization can lead to very tight competition in export-import activities or international trade, so that economic growth and the welfare of some people can be achieved broadly and evenly. With the government's role in supporting the competitiveness strategy and development of MSMEs, new features are needed.

Terror forestal, folk horror y brujería
Authors: Hormigos Vaquero Montserrat
Published: June 2023

El presente artículo se centra en el análisis de una parte del fantástico y del horror fílmico que se erige sobre lo que podríamos denominar terror vegetal. Estos filmes ponen en escena miedos primitivos y adaptativos y convierten el espacio forestal en un territorio simbólico y animista. Así ponemos el foco en el Folk Horror, subgénero en el que el fantástico vegetal ha medrado y ganado popularidad en el séptimo arte de las últimas décadas, donde el paisaje es un protagonista más de la trama, con unos actantes sometidos al aislamiento físico y mental, y donde se desata el componente sobrenatural. Por último, realizamos un recorrido por las figuras de la dríade y de la bruja desde el análisis de las cuestiones de género y en relación con la metáfora arquetípica mujer versus naturaleza dionisíaca.

Increased investment can help drive a country's economic development. In macroeconomics, investment also functions as a component of national income, gross domestic product, or gross domestic product. Investment is positively correlated with GDP or national income, when investment increases, GDP increases, and when investment decreases, GDP decreases. In the same context, Harrod-Domar developed a very legendary theory that economic growth requires capital formation in addition to capital stock. Capital formation can be seen as spending that increases the economy's ability to produce goods, or as spending that increases the effective demand for society as a whole. This requires investment to increase the ability to produce goods and services needed in the economy. Therefore, high and sustainable levels of economic growth are generally supported by increased exports and investment. In addition, Harrod-Domar emphasized that every economy must allocate a certain percentage of national income to replace damaged capital goods as an effort to grow the economy, thus requiring new investment as a capital stock.

CJEU case law on CHF loans the most important issues still awaiting for the decision (limitation of claims, remuneration for the usage of capital)
Authors: Ciesielski Jarosław
Published: June 2023

The Unfair Contract Terms Directive and provisions of the national law which implement that legal act realize a system of consumer protection against the usage of abusive clauses in contracts concluded by consumers and professionals. The large set of case law provided by the CJEU makes it possible to clarify the principles and scope of the consumers protection. However, it is not comprehensive, as there are still important legal issues that have not been yet resolved by the CJEUs judgements. They concern, in particular, such important issues for borrowers as determining the beginning of the limitation period for claims of the parties to the contract, as well as assessing the legitimacy of the lenders' claims for payment of remuneration for the use of the capital of the loan, which had been paid on the basis of a contract which has been declared void. That issues are addressed by references in preliminary ruling proceedings, currently conducted before the CJEU on the basis of questions submitted by Polish courts, in cases concerning borrowers. Examination of these questions leads to the conclusion, that the Court probably will take a pro-consumer position on these key issues, consistently advocating for the broad protection of the weaker party to the contract.

Authors: Sikoń Barbara
Published: June 2023

The main subject of this article is an analysis of the mechanism of settling investment disputes by means of international arbitration. This essay indicates that factors such as globalization, digitization, intensification of international economic contacts, especially between advanced countries and developing countries, have contributed to the increase in the number of investment disputes, which determines the need to resolve these disputes on the basis of the international law. Due to the origin of entities from different countries with different economic systems and various legal cultures, the international investment arbitration seems to be an effective way to resolve disputes, which provides private investors with guarantees of investment security. The article mentions the characteristic features of the international investment arbitration, such as: consensuality, dispute resolution by an independent tribunal, equality of parties to the proceedings, the possibility of dispute resolution based on the principle of equity, decentralized nature of arbitration. The essay also relates to the clauses appearing in the agreements on the promotion and mutual protection of investments. In addition to this, de lege ferenda conclusions regarding the increase of the transparency of the arbitration proceedings and allowance of the participation of so-called friends of the court in the investment arbitration have been mentioned in the present article as well.
