Authors: Peter Namakhwa
Published: July 2024

The research questions in this paper seek to address the challenges faced by Umodzi Park & Resorts in their centralized procurement system in order to bring efficiency and effectiveness to their day-to-day operations. This paper used empirical and explanatory research methods, which included the collection of primary data through a questionnaire, interviews with procurement personnel, and observations from procurement documents that provided the guidelines and process of procurement. A secondary source of data comes from written and electronic sources. This survey looks at the effectiveness of the centralized procurement system at Umodzi Park & Resorts by comparing the centralized model to the decentralized model and the centralized model to the combined centralized and decentralized models. The sampling type used is quota sampling, which only works with procurement personnel from the head office and its other two branches in Malawi. This study concludes with a recommended combined system of centralized and decentralized procurement and guidelines to follow for a successful procurement system.

Diuretics are widely used to treat pathologies of various genesis. However, the development of side effects during their long-term use remains a problem of traditional treatment regimens. The search for diuretics that would be aimed at inhibiting a key target molecule that is involved in the regulation of salt or water balance in the kidney, and certainly have a low level of toxicity and side effects, is an urgent task for researchers. Our preliminary screening of substituted quinones using in silico and in vitro methodology identified a number of effective compounds that outperform or compete with diuretics. The compounds are not "classic" carbonic anhydrase II inhibitors, but the pronounced diuretic effect of a number of compounds requires additional explanation. Therefore, the aim of the work was to study the effect of substituted quinones on the excretory function of rat kidneys to assess the prospects of their further structural modification and use as potential diuretics. Considering the experimental data, it should be noted that compounds AVD-6, AVD-7, AVD-8 and AVD-9 have pronounced diuretic activity. Thus, according to indicators of ex­cretory indices of electrolytes, it is possible to note the predominant influence of compounds AVD-6, AVD-7, AVD-8 and AVD-9 on excretion of sodium, potassium and chlorine from the body. Compounds AVD-6, AVD-7, AVD-8 and AVD-9, in contrast to Hydrochlorothiazide, which blocks carbonic anhydrase in the proximal part of the convoluted tubules and accelerates the excretion of potassium with from the urine, have a much lower excretory index as for these ions. Thus, our conducted research made it possible to identify a new, little-known class of hybrid molecular structures, namely (N'-(4-[(aroyloxy)imino]cyclohexa-2,5-dien-1-ylidene) aroylhydrazides (AVD-6, AVD-7, AVD-8 and AVD-9), which, in addition to affecting the excretory function of the kidneys, have significant diuretic activity and are  potential diuretics.

Published: July 2024

Diabetes mellitus is a common disease followed by cardiovascular complications, it is a metabolic syndrome with multiple etiology that is characterized by chronic hyperglycemia. Hypertension is a serious health condition that is significantly associated with the risks of heart, brain, kidney, and other diseases. Glycosylated hemoglobin (HbA1c) is diagnostic means of diabetes when fasting (venous) glycemia figures are 126 mg/dl (7.0 mmol/l). The purpose of this study is to focus on the diagnosis, and the treatment of the population with diabetes, identifying the necessary targets to guarantee clinical efficacy. Managing diabetes is challenging, and smoking can complicate it. People with diabetes who smoke often need larger doses of insulin to keep their blood sugar near normal levels. To assess the amount of vitamin D bound to hemoglobin, the study analyzed a number of laboratory parameters in patients with type 2 diabetes. The importance of this study is the estimation of the amount of enzyme-linked immunosorbent vitamin D. Laboratory parameters of diabetic patients were divided into three categories based on increased levels of glycosylated hemoglobin. Vitamin D levels were analyzed in these categories with increased HbA1c values. The influence of smoking and hypertension on laboratory parameters of diabetic patients was analyzed. The observations were carried out in the form of a database, and the methods that allowed the results for all parameters were followed. The data on the homogeneity of the selected information groups cover 150 patients diagnosed with diabetes mellitus, 40.67% were men, 59.33% were women. Similarly, (in fasting patients), a high OGTT-2-hour glucose level, the hemoglobin test indicates [A1C(HbA1c)] level, cardiovascular disease, and serum vitamin D. Overall, 47.33% of the patients were deficient in vitamin D. Decreased levels of vitamin D were associated with increased levels of glycosylated hemoglobin, while 22% were deficient. As a result, 74.67% of tobacco users had hypertension. Vitamin D deficiency may increase in patients with diabetes, with increased levels of glycosylated hemoglobin.

In modern conditions, providing the population with high-quality drinking water is becoming an increasingly urgent hygienic, scientific, technical, and social problem. Chlorine dioxide can be an alternative reagent for disinfecting drinking water. However, as with chlorine, dangerous by-products, particularly chlorites and chlorates are formed. The processes of development of morphofunctional changes in homeostasis remain insufficiently studied in this aspect. The objective is to determine the nature and peculiarities of changes in hematological indicators in the blood of animals due to the chronic impact of various concentrations of chlorates in drinking water to establish criteria for the hygienic assessment of their adverse effects on the body. The test animals were given drinking water with different concentrations of chlorates daily for 6 months: group 1 – control, group 2 – chlorates at a dose of 0.2 mg/dm³, group 3 – chlorates at a dose of 0.7 mg/dm³, and group 4 – chlorates at a dose of 1.2 mg/dm³. Evaluating the results of experimental studies, it should be noted that the most pronounced changes are observed in groups of animals that received chlorates in concentrations of 0.7 and 1.2 mg/dm³: a gradual decrease in the absolute number of leukocytes, the absolute and relative number of lymphocytes, relative to the indicators of the control group can be observed. In groups of animals that received chlorates in concentrations of 0.7 and 1.2 mg/dm³, a decrease in the absolute number of erythrocytes was observed during the 90 days of the experiment. It was established that the severity of the effects depended on the dose of chlorates and the time of exposure. Thus, the nature and features of changes in hematological indicators in the body of experimental animals during a chronic sanitary-toxicological experiment under the influence of chlorates in drinking water may indicate that chlorates affect the indicators of the blood system, being the indirect signs of disorders of other functional systems in the body, namely – slowing of redox reactions, hypoxic manifestations, reduction and weakening of the immune response and reactivity, etc.

Published: July 2024

Congenital cleft lip, alveolar process, hard and soft palate are common anomalies of the development of human organs and in terms of frequency occupy one of the first places among other defects of the human body. The clinical study and treatment of cleft lip and palate, malocclusions that accompany this defect have always been of great interest in orthodontics and orthopedic dentistry. This is due to the fact that malocclusions in this group of patients are complex and difficult to treat, as morphological changes are combined with significant functional disorders. The aim of the work was to demonstrate a clinical case of orthodontic and orthopedic rehabilitation of patients with congenital bilateral cleft lip and palate after cheilouranoplasty. A clinical case of a complex treatment of a 25-year-old female patient with bilateral cleft lip, alveolar process, hard and soft palate after cheilouranoplasty performed in childhood is presented. During the clinical examination, an irregular shape of the upper dentition was established due to its sharp narrowing and alveolar shortening in the area of canines and first premolars. A deep reverse bite was formed, a false progeny with a sagittal fissure of up to 10 mm, bilateral vestibular crossbite, contact on the first and second molars of the upper and lower jaws was observed, adentia 12, 22, 23. With a sharp narrowing of the upper dentition at the first stage of orthodontic treatment, Nord's apparatus was used. At the second stage, the brace technique was applied, namely, the straight arch technique. After expanding, lengthening the upper dentition, creating space for missing teeth, reducing the size of the lower dentition by removing 34, 44, the patient continued treatment at the orthopedic department. At an appointment with an orthopedic dentist, after an objective and subjective examination, according to Kennedy the patient was diagnosed as III class, I subclass of the upper jaw. Defects of the alveolar process of the upper jaw, formed as a result of adentia, connection of the oral cavity with the nasal cavity in places of non-union of the alveolar process were established. In this clinical situation, the manufacturing of a complete esthetic-cosmetic structure, namely a metal-ceramic dental bridge with obturating parts is indicated. Thus, the demonstrated clinical case can be considered as one of the methods of a complex orthodontic and orthopedic rehabilitation of adult patients with congenital cleft lip, alveolar process and palate.

Published: July 2024

Gottron's carcinoid papillomatosis of the skin is a rare and little-studied disease. The number of available scientific publications does not exceed several dozens, in Ukraine, in the last ten years, 2 works devoted to this pathology have been published. However, in parallel with the increase in diagnostic capabilities in a multidisciplinary hospital, there are periodically cases of establishing a diagnosis: Gottron's carcinoid papillomatosis of the skin. The lack of a clear understanding of the diagnostic and treatment algorithm creates additional difficulties in the treatment of Gottron's carcinoid papillomatosis of the skin. The course and features of this disease, namely: the presence of various concomitant pathologies, duration and unsatisfactory results of treatment, low patient compliance, etc., make its study relevant. This prompts a more detailed study and analysis of cases of successful treatment. The purpose of our work was to analyze a clinical case of treatment of Gottron's carcinoid papillomatosis of the skin in a multidisciplinary hospital using a multidisciplinary team approach, as well as to summarize the data related to the incidence, features of the clinical course and treatment of this disease given in scientific publications. A clinical case of successful treatment of a patient with Gottron's carcinoid papillomatosis of the skin is presented, a model of the interaction of a vascular surgeon at the stage of restoring the patency of the main arteries and preservation of the limb, a surgeon of the purulent-septicsurgery department at the stage of local and systemic treatment, a pathologist at the diagnostic and post operative stage, and a dermatologist for improvement of topical exposure and ambulatory monitoring is shown. Therefore, the analysis of this clinical case convincingly testifies to the successful capabilities of a multidisciplinary hospital in the treatment of Gottron's carcinoid papillomatosis of the skin, which can be taken into account when determining the treatment tactics of this disease. Coverage of this and similar cases in scientific publications of this rare disease will improve clinician awareness and treatment outcomes.

Authors: Demirdöğen Mehmet Fatih , Kılıç Süleyman
Published: July 2024

The AA2024-T3 alloy is a lightweight and durable material commonly used in the aerospace industry. This study investigates the impact of the rolling direction (RD) and strain rates on the alloy’s tensile properties. Tensile tests have been performed on samples oriented parallel and transverse to the rolling direction at varying strain rates (5, 25, and 125 mm/min). Samples parallel to the rolling direction have exhibited higher strength compared to those in the transverse direction (TD). At a strain rate of 5 mm/min, the maximum tensile strength in RD samples has been 530.72 MPa, while in TD samples, it has been 505.76 MPa. At 25 mm/min, the tensile strength has been 498.31 MPa in RD and 482.91 MPa in TD. At 125 mm/min, the tensile strength has been 508.52 MPa in RD and 480.36 MPa in TD. The increase in strain rate has had a complex effect on the mechanical properties. The total elongation values have also varied with strain rate, with the highest total elongation observed at 5 mm/min (0.168) in both RD and TD directions. These findings have highlighted the significant impact of the rolling direction and strain rate on the mechanical properties of the AA2024-T3 alloy, which should be considered in design and manufacturing processes.

Published: July 2024

Some lead-free piezoelectric ceramics are known to have high dielectric and piezoelectric properties but are limited by their brittle nature. A few amino acids have recently been reported to exhibit rather low dielectric and piezoelectric properties but have the advantage of being biocompatible and flexible. It would therefore be interesting to form a composite that will combine the inherent advantage of high dielectric properties from the ceramics and flexibility from the biomolecule. In this research, the properties of lead-free (K0.45Na0.51Li0.04)(Nb0.85Ta0.1Sb0.05)O3 (KNNLST) ceramics and L-lysine hydrochloride (L-LHCl) have been combined to produce dielectric composites. The samples were produced by mixing the constituents from 0 wt.% to 100 wt.%, pelletising and heat-treating them. Bulk density, X-ray diffraction, scanning electron microscopy, and dielectric characterisation were techniques used to determine the density, phases, morphology, and dielectric properties of the produced composites. The results show an increasing bulk density value from 1.2 g/cm3 for L-LHCl to 4.67 g/cm3 for the KNNLST ceramics. The morphology of the composite shows very tiny grains when small amounts of the ceramics were introduced. The L-LHCl transforms from an amorphous phase to a crystalline phase having the orthorhombic-tetragonal structure with the introduction of the KNNLST ceramics. The dielectric constant values increased with increasing KNNLST ceramics content from 10 @1 kHz to 200 for the composite with 80 wt%. KNNLST content. The dielectric loss values decreased for L-LHCl from 0.9 @1 kHz to 0.2 @1kHz. The electrical conductivity values increased with increasing KNNLST ceramics content. The results show that the composites produced from these constituents may be suitable for dielectric applications.

“Tierra de leche y de miel”: Ucrania en la obra de Manuel Chaves Nogales
Authors: Pozo Prado Juan José , Marchuk Maryna
Published: July 2024

La obra del periodista español Manuel Chaves Nogales contiene un importante corpus de textos que abordan la cuestión ucraniana. A través de artículos y libros escritos entre las décadas de 1920 y 1930, Chaves Nogales expresó su interés y preocupación por Ucrania dentro del contexto europeo. Sin embargo, lo que destaca no es el mero hecho de que un periodista se ocupe de temas de actualidad, sino que va más allá de la inmediatez y la novedad para examinar y profundizar en aspectos clave de las circunstancias sobre las que informa. Este estudio explora el tratamiento del tema ucraniano en obras de Manuel Chaves Nogales como "Corresponsal sevillano desde Madrid" (1920-1923), La vuelta a Europa en avión (1929), Lo que ha quedado del Imperio de los zares (1931), "Otras historias de Ahora" (1932-1936) y El maestro Juan Martínez que estaba allí (1934).
Chernóbil y Aleksiévich
Authors: Muñoz González Joan
Published: July 2024

El presente artículo analiza la fractura cronotópica que emergió en el imaginario histórico de la modernidad a raíz de la catástrofe de Chernóbil. Para ello, se parte de la mirada polifónica y testimonial que ofrece la escritora Svetlana Aleksiévich en Voces de Chernóbil, pero también se convocan otros autores provenientes del ámbito de la teoría de la historia y la crítica cultural. En primer lugar, se plantea una revisión sobre los modos de percibir el tiempo histórico antes y después del desastre nuclear. En segundo lugar, se dirige la atención a la dimensión geográfica de Chernóbil, haciendo hincapié en la nueva ordenación territorial y material de un espacio globalizado y arruinado. Por último, se realiza un breve examen concluyente sobre la propuesta narrativa que hace Aleksiévich, entendiendo que es el resultado meditado de una transformación radical en la manera de pensar y representar el mundo actual.
Yaifo, Jaffa, Haifa. Volverse-Mundo

Published: July 2024

El trabajo de Lina Meruane sobre Palestina comenzó en 2012 y comprende lo que a lo largo del texto se denominará su “Escritura Palestina”, una amalgama de piezas pertenecientes a diferentes géneros que, entendidas a través del marco de Deleuze y Guattari, constituyen lo que se considerará la “máquina literaria” de Meruane. El artíulo analiza los dos significados contenidos en el título del libro, "Volverse Palestina": el volver que implica un regreso a Palestina, que es inherentemente un volver imposible, un regreso allá donde uno no ha estado, y el volver que implica su convertirse en Palestina, un convertirse que no deriva de la herencia común, sino de una transformación interior producto de una serie de encuentros y colaboraciones inesperados. Este artículo considera la Escritura Palestina de Meruane como una forma de volverse Palestina que se produce no solo a través de una identidad heredada, sino también a través de una especie de contagio cultural. Siguiendo este argumento, la Escritura Palestina de Meruane puede entenderse como parte de lo que quedará enmarcado como otra forma de literatura mundial; una instancia de literatura deviniendo-mundo.

Johannesburgo: Núcleos intransigentes de significado
Authors: M. Llobera Laia
Published: July 2024

Este artículo de investigación profundiza en la intersección entre el pensamiento crítico, la literatura comparada y la teoría urbana a través del análisis de la teoría del intraducible de Emily Apter en el contexto del libro de poesía de la poetisa sudafricana Koleka Putuma, "Amnesia Colectiva". El concepto de intraducible de Apter sirve como marco teórico para examinar la utilización estratégica de elementos intraducibles por parte de Putuma en su poesía como medio de resistencia frente al discurso colonial. Concretamente, el artículo argumenta que Putuma emplea los intraducibles para desafiar y trastornar las expectativas e interpretaciones del lector colonial, reafirmando así su agencia y autonomía dentro del ámbito literario. Asimismo, este trabajo explora cómo los intraducibles utilizados por Putuma ofrecen una perspectiva sobre las complejidades de Johannesburgo como espacio urbano en disputa. A través del prisma de la teoría urbana contemporánea, especialmente la concepción de la nomosfera propuesta por David Delaney, el artículo analiza cómo la inclusión de elementos intraducibles por parte de Putuma en su poesía proporciona una comprensión matizada de las dinámicas sociales, culturales e históricas complejas de Johannesburgo. Mediante un análisis textual minucioso, el artículo revela cómo los intraducibles funcionan como marcadores simbólicos que desvelan las capas nomosféricas de la ciudad, arrojando luz sobre sus políticas espaciales, dinámicas de poder y tensiones socioculturales.

El estudio se centra en el análisis bibliométrico de las zonas periurbanas en Latinoamérica, abordando las causas y efectos de las transformaciones en estos espacios. La metodología empleada permite evaluar logros científicos y tendencias de investigación, utilizando bases de datos como SCOPUS y Latindex. Históricamente, la urbanización ha llevado a la conversión de áreas rurales en periurbanas, impulsada por factores demográficos y económicos. Este proceso genera cambios significativos en el uso del suelo, transformando prácticas agrícolas en desarrollos residenciales y comerciales. Las zonas periurbanas, consideradas espacios de transición, enfrentan desafíos como la fragmentación del suelo y la pérdida de biodiversidad, además de problemas socioeconómicos como la gentrificación y la falta de servicios básicos. En Latinoamérica, estas áreas presentan dinámicas complejas, con una mezcla de usos de suelo que reflejan desigualdades en el acceso a recursos. La gestión sostenible del periurbano es crucial para mitigar impactos negativos y maximizar beneficios para las comunidades locales, resaltando la necesidad de políticas públicas efectivas que consideren el contexto territorial específico.

Published: July 2024

This paper aims to analyze the problem of sexual violence in Aceh using the Multiple Perspective Analysis theory introduced by William N Dunn. Sexual violence is complex problem with cases like an iceberg phenomenon where few cases are visible or openly reported while the majority of the problem remains hidden or undetected. Sexual violence cases in Indonesia are difficult to handle in many provinces, such as Aceh, where this problem has been a protracted problem that must be resolved with effective solutions. The method used in this paper is a qualitative method with secondary data sources and literature studies. The results found by the researcher show that the problem of sexual violence in Aceh caused by multiple factors ranging lack of availability for safe house facilities and the unoptimal service system from the PPA unit at Aceh police, TPKS Law that cannot be implemented optimally due to overlapping regulations with Qanun Jinayat, and the taboo discussion of “sex” in the community that impacts survivors who often get negative stigma from the community. This research provides useful implications for a sustainable sexual violence response system in Aceh that requires effective leadership from the government, efficient infrastructure, and an effective response system.

Traffic congestion has a significant negative impact on regional economic activities and decreases community productivity.  The purpose of this study is to analyze the sources of congestion problems in Malang City and the best way to solve them with a high level of effectiveness. The method used is qualitative with secondary data study. The researcher used a classification-based analysis approach to address the congestion problem with a multidisciplinary approach and explore the root of the congestion problem in Malang City. The first step involves logical division to classify the problem situation into several components. Second, logical classification refers to the act of combining different circumstances, things, or individuals into larger groups or classes. The results showed that the source of the problem was found in the high volume of vehicles and disorderly parking due to the growing accumulative population mobility. As a result, the capacity of Malang City is not able to accommodate this. Recommendations from alternative options resulting from the satisficing method analysis were carried out. In the end, the option to reorganize the road space is the option that is considered to meet all the criteria.

The new service paradigm emphasizes community satisfaction, especially in the millennial era who are critical of government administration. This research aims to evaluate the effectiveness of this thesis program entitled Implementation of the District Integrated Administrative Services Policy in Lilirilau District, Soppeng Regency, which is motivated by the government's desire to bring closer, simplify and speed up licensing/non-licensing administration services at the sub-district level. The data collection technique is to use observation, interview and documentation techniques. Meanwhile, data analysis techniques use data reduction, data presentation and drawing conclusions. Based on the results of the analysis, it can be concluded that there are three District Integrated Administrative Services policies in Lilirilau District that have been implemented well and there are three that have not been implemented well and provide benefits to the community, especially regarding administrative services. The implementation of PATEN in Lilirilau sub-district is also in accordance with applicable provisions as mandated by Minister of Home Affairs Regulation Number 04 of 2010 concerning Guidelines for District Integrated Administrative Services. Even though in its implementation there are several shortcomings that need attention, such as standards & policies, resources and disposition, basically these three indicators are important factors in the implementation of PATEN which cause obstacles to the service process at the Lilirilau sub-district office. This research will not only provide an academic contribution, but can also be a basis for local governments to formulate strategies for improving public services that are more effective and responsive to community needs.

Authors: Isgunandar Isgunandar
Published: July 2024

Leaders must have the courage to take necessary action against members who are less productive or violate the rules, in order to maintain the interests and integrity of the organization. This research aims to evaluate the effectiveness of implementing the main leadership functions at the Sinjai Borong District Office, Sinjai Regency. In an organizational context, leadership factors have an important role in driving and directing goal achievement. The research method used was descriptive qualitative, with data collection through interviews, observation and documentation, involving 5 informants. Data analysis uses three stages, namely data reduction, data presentation, and drawing conclusions. The research results show that the implementation of the main leadership functions is not optimal, especially in the consultation and control functions. The limited time of sub-district leaders who hold concurrent positions outside the office hampers communication with their subordinates. Even though there are several indicators that show effectiveness, there are still several things that need to be improved so that the leadership function can run well and support the achievement of organizational goals.

there are still many BUMDes that do not operate, do not submit reports, their establishment is not supported by feasibility studies and they have not been orderly in their administration and reports The method used in this research is a qualitative method with a descriptive approach. To obtain data and information, researchers conducted interviews with managers of Village-Owned Enterprises and the Pulo Jantan Village community. In addition, researchers also conducted observations and documentation to answer research problems. The data that has been obtained is analyzed using Kristianten's Transparency theory, namely Availability and Accessibility of Documents, Clarity and Completeness of Information, Process Openness and Regulatory Frameworks that Guarantee Transparency. Based on the research conducted, it can be seen that the Transparency of Management of Village-Owned Enterprises cannot be said to be Transparent. This is shown in the Document Availability and Accessibility indicator, namely the absence of publication media as a form of easy access provided to the public. The second indicator is Clarity and Completeness of Information, namely information related to the annual village meeting is still not clearly provided to the community. The third indicator is Process Openness, namely information related to the BUMDes program management process is still not optimally provided to the community.
