The insufficiently high quality of the surface of metal castings, which are made in sand molds, is due to the formation of various surface defects, of which galling is the most common. Cleaning castings from scorch leads to additional costs of material and labor resources, which can reach 40-60% of the total labor intensity of production. The process of increasing the strength of the non-stick coating of casting molds and rods can be implemented by optimizing its composition. According to the result of the analysis of thermochemical reactions at the contact interface "melt - mold" in the process of heat exchange between the casting and the casting mold and related physical processes, as well as hydrodynamic processes of interaction in the contact zone, in particular, specific for graphitized cast iron, in order to prevent surface defects on the internal cavities of body cast iron castings, after experimental and industrial work, non-stick coatings of increased resistance were developed and applied in foundry production for sand molds and rods. Coating compositions were completed according to the concept of partially directing the energy of the high-temperature exposure of the metal to chemical transformations in the non-stick coating and the contact zone of the sand mold with the formation of compounds that would contribute to the sintering of the particles of the surface layer of the mold at the temperature of its heating from the contacting metal. This served as a means of preventing cracks in such a layer and avoiding cracks and mechanical burning on the surface of castings. A method of reducing the metal pressure from the pre-shrinkage expansion of graphitized cast irons during its action on the surface of the walls of the casting cavities by the timely partial weakening of the vacuumed casting mold without disturbing the given geometry of the casting when applying the method of casting according to gasifying patterns has also been developed.

The purpose of the work is to invent a method and develop a tool for effective drilling of strong and especially strong rocks with the least expenditure of both energy and money for the drilling tool. Currently, in rocks, the most time-consuming and expensive is drilling wells in strong and especially strong rocks. Despite numerous attempts to solve the problem of drilling strong rocks, an effective solution to this problem has not yet been found. The problem is that the introduction of drilling tools into these rocks requires considerable effort and work to destroy these rocks. This requires high strength and durability of the drilling tool, which is limited by the properties of known materials used. The solution to this problem may be to strengthen strong and drill wells in particularly strong rocks by transferring them to a stressed state or creating a grid of cracks in them, which will significantly reduce the effort and work to introduce the tool into the rock, as well as its abrasive wearout. This article proposes a new method and device for creating cracks on the mine face surface in durable rocks for their further drilling by cutting. A brief description of the new method of impact-cutting drilling of strong rocks is given. Sketch drawings of a previously unknown device for impact-cutting drilling of strong rocks are provided and a description of its work is given. The advantages of this method and the device are indicated – in solving the problem of drilling strong rocks.

Experiential Tourism and Homestays in Kerala
Authors: Varma T.N. Narendra
Published: May 2023

When we undertake leisure travel, in most cases, we want to enjoy the history and civilization of a distant location, relax in an eco-friendly destination, or experience the beauty of local culture like dance, drama, theatre, handicrafts, or any other fine arts. These experiences become memorable and remain in our minds for longer duration. The interests for experiential tourism have gained more importance among young generations and scholars and tourism practitioners of late. This process or trend in leisure travel is also known as “Immersion travel”. Uniqueness of the destination and authentic experiences are the hall marks of experiential tourism. Tourism is a principal contributor to the State’s economy in Kerala. Kerala has topped the list of the ‘Most Welcoming Region’ in India, according to a survey conducted by leading digital travel platform Booking.com. Because of its uniqueness, National Geographic Traveler selected Kerala as one of the best 50 destinations of a life time and also as one of the thirteen paradises in the world. Of late, the Responsible tourism destinations in the state and the new STREET (acronym for Sustainable, Tangible, Responsible, Experiential, Ethnic, Tourism hubs) projects have attracted many enthusiastic experiential travelers. Homestays in Kerala are an alternate accommodation option and they are part of the sharing economy. They also provide opportunities for Village tourism and authentic socio-cultural experiences. The homestays in Kerala are concentrated in those districts where there are a lot of destination attractions. The study concludes by saying that Experiential tourism is a special kind of tourism where the traveler and his/her direct experiences, are an opportunity for enrichment of cultural, social and emotional enrichment. Because homestays are comparatively economical and they provide security and warmth of a home and also provide to learn a new culture, they attract many experiential travelers.

A Review on Fall Armyworm (Spodoptera frugiperda) Insecticide Resistance
Authors: Eva Mamahit Juliet Merry , Kolondam Beivy Jonathan
Published: May 2023

The commonly known fall armyworm (Spodoptera frugiperda) is an important pest of corn, cotton, and other crops in the Americas, Africa, and Asia. The species is native to tropical and subtropical regions of the Americas, but it has spread to other parts of the world in recent years. The pest has a wide host range, including important crops like corn, cotton, rice, sorghum, and vegetables. Large populations of fall armyworms can cause significant damage to crops, leading to reduced yields and lower crop quality. The threat of insecticide resistance in S. frugiperda is a growing concern for agricultural production and food security. Insecticides are an important tool for managing fall armyworm populations, but the development of resistance to these chemicals has become a major issue in many regions. This pest has shown resistance to several classes of insecticides, including pyrethroids, organophosphates, and carbamates. To effectively manage insecticide resistance in S. frugiperda populations, it is important to consider these factors and develop integrated pest management strategies that take them into account. This may include the use of alternative control methods, such as biological control and cultural control, and the judicious use of insecticides to minimize selection pressure for resistance development. It is important for farmers, researchers, and policymakers to work together to develop and implement integrated pest management strategies that can effectively manage S. frugiperda populations while minimizing the development and spread of insecticide resistance.

Authors:   , de Sousa Barbosa Ivson
Published: May 2023

A mineração consiste em uma atividade humana exercida desde a antiguidade, mas que provoca alterações ambientais no solo e vegetação. No Cariri da Paraíba a exploração de bentonita apresenta grande importância sócio-econômica e caracteriza-se pelo decapeamento do topsoil, originando grande volume de terra, com CTC alta, mas com baixo conteúdo de matéria orgânica e que são acumulados na área de lavra. A pesquisa objetivou avaliar a contribuição do composto orgânico no crescimento inicial de espécies nativas cultivadas em topsoil de mineração. A pesquisa foi conduzida em duas etapas: uma no viveiro e outra no campo. No viveiro aplicaramse doses de composto orgânico (0,0–5-15-25 % v/v) no topsoil, estudando-se o crescimento inicial da craibeira (Tabebuia aurea), jureminha (Desmanthus virgatus) e pau ferro (Caesalpinia ferrea) por meio da avaliação da altura e diâmetro, durante 105 dias. Em seguida as mudas foram plantadas no campo, quantificando-se as mesmas variáveis por 120 dias. No viveiro e no campo o composto aumentou a altura e o diâmetro da craibeira, jureminha e pau ferro principalmente aos 105 e 120 dias da semeadura e plantio, respectivamente.

Published: May 2023

O trabalho objetivou analisar a dinâmica da chuva de sementes em um sistema ecológico em área de Caatinga no Semiárido paraibano. O período amostral do estudo foi de janeiro a dezembro de 2019 e foi executado no Espaço Experimental Reservado para Estudos de Ecologia e Dinâmica de Caatinga – Área I do Laboratório de Ecologia e Botânica – LAEB/CDSA/UFCG (7°39’38.8’’ S e 36°53’42.4’’ W; 538 m de altitude). A área de estudo possui uma extensão de 1,05 ha e nela foram dispostas 96 parcelas de 10 x 10, sendo que foram definidas 48 parcelas para o estudo de chuva de sementes. Nestas parcelas reservadas, foram dispostos coletores com dimensões de 0,25 m² (0,5 x 0,5 m), totalizando 12 m² de área amostral. Mensalmente o material foi recolhido e a triagem realizada no Laboratório de Ecologia e Botânica. Em seguida o material foi pesado em balança analítica de precisão de 0,001g. A massa total das frações foi 3.521,3651 g em 12,0 m², correspondendo a 2.934,47 kg/ha1 de material total. A fração folha representou a maior deposição na maioria dos meses, evidenciando a sua maior expressão no mês de setembro onde não houve precipitação. Com relação ao percentual de massa por fração, o componente folha representou a maior contribuição anual, seguida de galhos e frutos, sendo que cascas obteve a menor deposição. No percentual de sementes depositadas, observou-se que ocorreu variações sazonais na chuva de sementes, pois no período chuvoso obteve a maior deposição de sementes e no seco houve uma queda na contribuição. Relacionando a riqueza de espécies e precipitação, observou-se que a maior riqueza de espécies foi no mês de junho, onde os valores de precipitação foram baixos. Quanto ao percentual de sementes e contribuição de riqueza de espécies, maio teve maior presença de sementes, porém a riqueza de sementes superou todos os meses no mês de junho. Portanto, a chuva de sementes mostra-se um mecanismo de extrema importância para ações de reversão de áreas degradadas e estudos voltados para a regeneração natural.

Authors:   Department of Radiology, University Hospital St. Marina, Medical University Varna, Bulgaria., Georgiev Radoslav
Published: May 2023

Chronic Lymphocytic Inflammation with Pontine Perivascular Enhancement Responsive to Steroids (CLIPPERS) syndrome is a rare neurological disorder with uncertain etiology, pathogenesis and clinical course. Pittock et al. in 2010 first described this chronic inflammatory neurologic condition, which preferably affects the brainstem. There is an infiltration with inflammatory cells of the affected regions and typical dotted and curvilinear contrast-enhancement zones on magnetic resonance imaging (MRI), including leptomeninges. I present one case of a 41-year-old male with gradual onset of suspected infectious disease and neurological worsening with typical MRI features, with a biopsy confirmed diagnosis and follow-up for 15 months. The MRI findings and the evolution of the disease can narrow the differential-diagnostic spectrum in such a clinical case.

Published: May 2023

Background: The placenta reflects the prenatal problems that are linked to high perinatal morbidity and mortality both macroscopically and microscopically. A pregnancy syndrome called pre-eclampsia has terrible consequences for both the mother and the unborn child. It may result in more frequent inductions of labor, fetal growth limitation, respiratory issues in newborns, increased admission rates to neonatal critical care units, and an elevated risk of perinatal or fetal death. To understand the relation of preeclampsia and fetal growth identification of its effects on various components of the placenta is mandatory hence the current study was designed to evaluate the Placental Terminal Villi, Capillaries, and Intervillous Space in Normal and Pre-eclamptic Pregnancies. Methodology: It was a cross sectional study, carried out on 50 samples of placentas, out of which 25 were preeclamptic and 25 were normal. The placentas were recruited after cesarean session, processed as per guidelines and were analyzed for histopathological examination. The set inclusion criteria were Registered cases of Pre-eclampsia, Blood Pressure ≥ 140/90 mmHg, Parity 0 – 4, Age of mother (25 – 35) Years., Gestational Age (36 – 42) Weeks, Mode of delivery Cesarean Sections. The set exclusion criteria were known hypertensive patients, and patient diagnosed with other chronic illnesses. Results: Number of terminal villi, Transverse diameter of terminal villi (μm), Intervillous space (μm), and Transverse diameter of terminal villous capillaries decreased significantly (p=0.001) in preeclamptic group however, Number of terminal villous Capillaries were found to be increased in preeclamptic group (p=0.001). Conclusion: Preeclampsia leads to more significant alterations in placental structure compared to normal pregnancies, emphasizing the importance of early detection and management of this condition to improve maternal and fetal outcomes.

Published: May 2023

Introduction: Delirium is a common postoperative complication following cardiac surgery, and it can lead to a range of adverse outcomes, including increased length of hospital stay, cognitive decline, and mortality. Objectives: The main objective of the study is to find the meta-analysis of factors which influence delirium following cardiac surgery. Material and methods: The study is a systematic review and meta-analysis of observational studies that investigate the potential risk factors for delirium following cardiac surgery. A comprehensive search of electronic databases such as PubMed, Embase, and Cochrane Library was conducted to identify relevant studies published up to a specific cut-off date. The search terms would include combinations of relevant keywords such as "delirium," "postoperative," "cardiac surgery," and "risk factors." The search strategy included studies published in English language journals from inception to the date of the search cutoff. Results: The systematic review and meta-analysis included 20 observational studies with a total of 4,500 patients who underwent cardiac surgery. The incidence of delirium ranged from 5% to 50% across studies. Meta-analysis showed that several factors were significantly associated with an increased risk of delirium following cardiac surgery. These factors included advanced age (pooled OR 2.50, 95% CI 1.75-3.56), pre-existing cognitive impairment (pooled OR 3.15, 95% CI 2.01-4.93), longer cardiopulmonary bypass time (pooled OR 1.85, 95% CI 1.28-2.66), and higher serum creatinine levels (pooled OR 2.10, 95% CI 1.47-3.01). The use of benzodiazepines was also associated with an increased risk of delirium (pooled OR 2.67, 95% CI 1.87-3.81). Conclusion: In conclusion, our meta-analysis provides evidence that older age, pre-existing cognitive impairment, longer bypass time, and depression are significant risk factors for the development of delirium following cardiac surgery. These findings have important implications for the management of patients undergoing cardiac surgery, as identifying patients who are at higher risk of developing delirium can help to prevent its occurrence and improve patient outcomes.

Published: May 2023

Background: In Pakistan Plasmodium falciparum has been on the rise over the last few decades. Objective: This study primarily focused upon finding out the prevalent occurrence of malaria caused by Plasmodium falciparum in Pakistan. Methodology: This research analyzed different variables related to the respondents (n=209) of the study. The variables included age, occupation, education, patient’s visit to the hospital, transmission of malaria, prior treatment of the patient (if any), usage of long lasting insecticidal nets (LLINs), hygienic/unhygienic conditions and insecticidal spraying. Investigative analysis was purely based upon a questionnaire followed by the fundamental microscopic and polymerase chain reaction (PCR) for assessing the disease index. Results: The results indicated that out of 209 respondents of the study, 100% tested positive for malaria whereas, only 179 (85.6%) cases were confirmed via PCR analysis and were chosen for further investigations. Males (67%) were found to be more prone for malarial infection. Respondents in the age group of 26 to 35 years were the most (43.5%) vulnerable to this infection. 32.9% laborers, as compared to any other occupation affected by plasmodium. About 77.6% of people had already been infected by malaria and were treated, but only 14.5 % people visited the hospital. In addition to this, merely 12.2% respondents had used LLINs and 2.23% of them had utilized insecticidal spray. Conclusion: Lack of awareness, selfmedication, unhygienic environment, unemployment, and political instability contributed to malarial transmissions. Keywords: Malaria, Plasmodium falciparum, Pakistan, Microscopy, PCR.

Published: May 2023

Background: Acute appendicitis (AA) is the most common clinical condition worldwide. In Pakistan, about 400,000 appendectomies are routinely carried out in surgical departments yearly. This study aims to find the latest and updated information regarding the diagnostic accuracy of CRP levels in AA. This will help surgeons make timely decisions, thus reducing the morbidity and mortality associated with complicated appendicitis. Methods: This descriptive cross-sectional study was performed at KTH Peshawar from February to august 2018. It was designed to analyze C-reactive protein levels among acute appendicitis patients using positive and negative predictive values. Histopathologically confirmed appendicitis patients were included. Results: In the current study, 216 patients suffering from Acute appendicitis were studied observed. The symptoms duration was < 2days in 75% patients while >2 days symptoms were found in 25% population. Majority patients were poor (46%), followed by middle class (42%), and rich (12%). Obesity was only observed in 22% patients suffering from AA. Diabetes and hypertension was observed in 18% and 15% patients respectively. Diagnostic accuracy of acute appendicitis was also calculated between CRP and Histopathology findings based on age, diabetes mellitus, gender, hypertension, obesity, and period of symptoms. Conclusion: Our study concludes that the acute appendicitis symptoms appeared in less than two days. Acute appendicitis predominantly found in poor and middle class patients. Acute appendicitis should be diagnosed based mostly on its clinical symptoms. Despite the fact that CRP is a particularly helpful marker in the clinical diagnosis of acute appendicitis, general surgeons must apply their clinical judgement. The function of CRP in acute appendicitis should be examined in future research with a bigger sample size.

A major role in eliminating the resistance to change is played by the c
Theoretical aspects of business models and the challenges of their Innovative transformation under the current conditions
Authors: Emelian Vitalie
Published: May 2023

The present article presents the analysis of a number of relevant sources for a better understanding of the business model concept, its evolution, prior to describing the major trends that affect the theory and practice of the concept. We approach the business model as a simplified description of how a company does business and earns money without having to go into the complex details of all strategies, processes, units, rules, hierarchies, work flows and corresponding systems. For a better conceptual perception of the business model, we considered it important to highlight its components. In this line of thinking, we analyse various opinions on the business model components. Worth mentioning is the fact that business models are constantly evolving as companies react to changes.

Authors: Noroc Dorel
Published: May 2023

The pandemic crisis and war in the region have led states to identify new revenue mobilization measures to cope with rising public spending. An essential tool at their disposal is the optimization of tax expenditures, which must be achieved with minimal adverse effects on economic and social processes. For this, it is necessary to go through some actions related to identifying tax expenditures and their evaluation through the lens of lost budget revenues. Also, the evaluation process includes identifying the objectives for which they were introduced and the degree of achievement of these objectives. Following this evaluation, the decision-makers will analyse comparatively whether other budgetary-fiscal instruments could be applied to achieve the goals, such as expenditure programs, which would ensure greater efficiency of public policies.
