A press tool is used to cut or form a thin plate into the desired shape with a pressing process or a press machine. One of the main things in the design of the press tool is the calculation for determining the type, size and, material of the spring. The spring in the press tool design is placed on the stripper as a pressure plate material before it is formed. The problem that often occurs in the design of the press tool is the initial force of the spring and the number of springs often have high values. This has an impact on the difficulty of the operator in installing the spring during assembly. The installation on the press machine requires more energy that exceeds the operator's power. This problem is often a challenge in itself both in terms of designing and manufacturing press tools. Assumptions and limitations of the problem of the design is 12,64 kN. This force is used for the educational practicum materials. Based on the design calculations the number of springs needed are 4 springs. While the hydraulic required is 10 tons. The results obtained based on simulation analysis using Solidworks software, show that with the number of springs and hydraulics calculated and based on the design form of the stripper installation tool, it is in the safe category.

Welding is often used in industry as a joining technique, one of which is Micro Resistance Spot Welding (MRSW). MRSW was carried out to know the maximum load and shear stress produced on separate worksheets using AISI 304 and aluminum alloys and then connected using a lap joint. This study uses weld current, weld time, and emphasis on the electrodes. In this, welding is done constantly and does not use cooling. The currents used in welding are 140, 280, and 420 A, then varied with the welding time of 24 ms, 34 ms, and 44 ms and combined with a pressure of 1.3 bar. After welding, the welding results are tested using tensile tests and weldability tests. The results of the study were taken with the highest maximum load on a differentiated worksheet. The highest maximum load is generated at the connection of AISI 304 with AISI 304. In contrast to the connection using aluminum alloys, the resulting load will decrease.

Motorcycle users in 2019 reached 133,617,012 units in Indonesia. The impact of a large number of motorcycle certainly attracts the interest of the industry to produce two-wheeled automotive vehicles. The piston is part of the engine that functions as a compression barrier in the combustion chamber, the piston material is aluminum alloy. Therefore, research was carried out on making pistons with investment casting methods, physical and mechanical patterns from 3D printers on pistons. This research starts from drawing the piston using CAD (computer-aided design), making a printed pattern from a 3D Printer machine with PLA (polylactide acid) material. The mold pattern is coated with a mixture of gypsum cement and silica powder. The casting process with a pouring temperature of 750ᵒC and a mold temperature of 200 ᵒC, 250 ᵒC, 300 ᵒC, 350 ᵒC, and 400 ᵒC. The results showed the largest grain size at a mold temperature of 400ᵒC. The highest hardness at 200 ᵒC mold temperature is 47.00 HRB and the lowest hardness at 400 ᵒC mold temperature is 40.56 HRB. The higher the temperature of the mold used, the level of porosity of a material will decrease. This is due to the temperature difference when pouring the molten metal and the lower mold temperature. This makes the metal solidification time longer. The higher the mold temperature, the slower the solidification time, the larger the grain structure, and the decreased hardness.

Solid oxide fuel cells (SOFCs) operate at high temperatures (800oC–1000oC), generating fast layer disintegration (anode, electrolyte, and cathode). The goal of the research was to lower the operating temperature in the medium temperature range. The SmBa0.5Sr0.5Co2O5+δ (70%) + Ce0.8Sm0.2O1.9 (30%) oxide was investigated as a cathode material for IT-SOFCs using samaria-doped ceria (SDC) as the electrolyte. The solid-state reaction approach is used to prepare the SBSC73 powder. In this study, thermal, electrochemical properties, and power density of the SBSC73 perovskite cathode are investigated. The weight loss on heating is due to the loss of part of the oxygen lattice and the reduction of Co4+ to Co3+. The oxygen reduction reaction (ORR) is dominated by the electron transfer process at a temperature range between 600°C to 800°C. The activation energy (Ea) of the perovskite SBSC73 cathode polarization resistance reaches 95.1 kJ mol-1. The highest power density of SBSC73 single-cell reaches 68 mW cm−2 at 600°C.

Environmentally friendly composites continue to be developed from kapok tree fiber (Ceiba pentandra) with an epoxy matrix. This study aims to characterize the tensile behavior of single fiber and its composite, the pull-out properties of kapok tree fiber, and morphology of the fiber. Kapok tree fibers were varied in the NaOH solution and the AESO polymer. Single fiber tensile test and pull out refer to the ASTM D3379-75 and ASTM E399 standards, respectively. The composite manufacturing method used in this research was the infusion vacuum resin method with reference to the ASTM D638 standard. The results of the tensile test (composite) showed that the kapok bark fiber with the characteristics of NaOH + Coating had a greater tensile strength (197,88 Mpa), than that without treatment and NaOH treatment. Of all the characteristics of the kapok bark fiber, the highest value of the tensile strength was the fiber treated with NaOH + Coating (KNC). The results of fiber morphology showed proved that the NaOH treatment increased the surface hardness by eliminating the bonds of surface crystallinity, topography, water absorption, unit cell structure and fiber orientation. These results indicate that kapok tree fiber treated with 7% NaOH + coating with AESO polymer has high potential as a structural material to replace wood or textile materials.

The main focus of this research is to modify the straight pipe of the Citronella essential oil distillation condenser using a helical coil pipe to shorten the distillation time. This study aims to obtain an effective shell-side fluid volumetric rate to shorten the distillation time. The volumetric rate of the shell side fluid varies from 0.72 to 3.66 LPM at a constant pitch ratio of 2.10. Recording of data in the form of temperature, volumetric rate of shell side water, and tube side steam after steady state is reached. The experimental results show that the effectiveness increases with the increase in the volumetric flow rate of the shell side fluid, where the maximum effectiveness at the volumetric flow rate of 3.66 LPM is 69.99%, while the minimum effectiveness at the volumetric flow rate of 0.72 LPM is 44.39%. The results of the validation of the effectiveness of the condenser show a trend curve that is identical to the previous research, with an average deviation of 5.67%. The maximum volumetric flow rate with a minimum distillation time of 120 minutes with a condensate volume of 8 ml or 240 minutes is smaller than the result of straight-pipe condenser distillation by UKM. The maximum effectiveness is due to an increase in the Reynolds number on the shell side, which results in an increase in the actual heat transfer. It can be concluded that the maximum condenser effectiveness at a maximum volumetric rate of 3.66 LPM could be used for refining Citronella essential oil by SMEs.

Published: May 2023

Malleable cast iron is one of the cast irons that has excellent forging properties. Malleable cast iron is the result of heat treatment of white cast iron, so that cementite is decomposed to form graphite in the form of rosettes.  Malleable cast iron is often used for tooling and on railway components. Testing to determine the fatigue limit of malleable cast iron is very important so that it can find out the maximum fatigue load that malleable cast iron can receive. Fatigue testing was carried out with variations in loading angles of 1o, 2o, 3o, 4o and 5o. From the tests carried out, the fatigue limit of malleable cast iron is below a voltage of 100.4 MPa. Metallographic testing is also carried out to determine the microstructure in malleable cast iron. The microstructure formed in the specimen is in the form of graphite in the form of a rosette and there is a ferrite phase, so the malleable cast iron tested is malleable matrix ferritic cast iron. Fault surfaces in specimens were also observed through visual observation and scanning electron microscopy (SEM). Through visual observations on the surface of the fault, beachmark are seen, in specimens given a loading angle of 1o has a wider area of beachmark compared to other loading angles. This is because the smaller the loading angle, the smaller the voltage so that the crack propagation area will be wider. SEM observations indicate that the fracture that occurred was a transgranular fracture.

Heat recovery from available waste heat is an essential method in renewable energy processes due to the ability to generate electricity by using Organic Rankine Cycles (ORC). The process model is developed with the Cycle Tempo software. Fluid properties were analyzed with Reference Fluid Properties (REFPROP) software. This research presents a thermodynamic comparison of the Basic Organic Rankine Cycle (BORC) and Recuperative Organic Rankine Cycle (RORC) for waste heat recovery applications using pure refrigerants R-141b, R-245fa, R-123, and R-21. By performing simulations for heat source high-temperatures ranging from 160 to 200 °C. The comparison between BORC and RORC performance parameters and refrigerant properties was evaluated on the heat source temperature. Research shows that RORC produces higher thermal efficiency but has lower irreversibility than BORC. RORC has a maximum thermal efficiency of 12.67%, and BORC has a thermal efficiency of 11.49% for refrigerant R-141b at a flue gas temperature of 160 °C. The thermal efficiency of the ORC increases as the temperature of the heat source increases.

The objective of the study was to determine the main causes of osteoporosis in chronic kidney disease, chronic obstructive pulmonary disease, pulmonary sarcoidosis and understand how the disease develops in these conditions.

Materials and Methods. To study the mechanisms of developing secondary osteoporosis, a literature review was conducted.

Results. Secondary forms of osteoporosis account for approximately 15-20% of reported cases and result mainly from concomitant diseases or from using drugs that have a negative effect on bone tissue. Despite its inert and stable appearance, bone tissue is a metabolically active, continuously renewing system. Throughout life, it continuously undergoes remodeling cycles involving the two main processes: the first one is called bone resorption and involves the breakdown of old bone followed by the destruction and removal of both the mineral substance and the organic matrix from resorption sites; the second one is called new bone formation and involves bone matrix synthesis and its subsequent mineralization. The imbalance between these two processes, the predominance of bone resorption over bone formation, is the key link in the pathogenesis of osteoporosis. Such an imbalance reflects the impairment of the major mechanisms of systemic hormonal and local (cytokine) regulation of cellular activity and occurs in secondary osteoporosis.

Conclusions. To date, at the stage of providing medical care to patients with chronic bronchopulmonary diseases and chronic kidney disease, inadequate attention is paid to timely diagnosis and treatment of concomitant osteoporosis. The latter often develops as a secondary condition due to systemic inflammation, severe hypoxia, low physical activity, taking inhaled and systemic glucocorticoids. Its signs are not clinically apparent; hence, it is referred to as the ‘silent epidemic. Since osteoporosis has no pathognomonic symptoms and its clinical presentation is rather vague, in patients with chronic bronchopulmonary diseases and chronic kidney disease, its early diagnosis by determining mineral bone density is recommended to prevent the development of severe complications, including low-energy fractures.

Authors: Huranych Serhii , Huranych Tetyana , Zayats Olya
Published: May 2023

Topicality. Pancreatic hormones play an important role in the process of remodeling of hard periodontal tissues. Violations of carbohydrate metabolism that occur under conditions of isolated insulin resistance (IR) and in combination with iodine deficiency (ID) can be the cause of dysmetabolic disorders of mineralization/demineralization physiological system of tooth-maxillary complex.

The aim. To study the changes of remodeling processes of hard periodontal tissues in rats with isolated IR and impaired glucose tolerance against the background of ID.

Materials and methods. The examination was carried on 90 male rats, which were divided into three groups: control (intact animals), group of rats with IR under conditions of adequate iodine supply, and with IR against the background of ID. The system of carbohydrate metabolism was studied by the level of insulin in blood serum, glucose and glycosylated hemoglobin (HbA1c) of blood with the following calculation of HOMA-IR index. The processes of mineralization/demineralization were detected by the content of calcium, magnesium, zinc, manganese, copper in cementum of tooth root and alveolar process, and by the activity of acid and alkaline phosphatases in blood serum.

Results. Keeping of animals on a high-fructose diet led to the development of carbohydrate metabolism disorders (increase blood glucose and HbA1c levels, blood serum insulin, HOMA-IR index) and changes of remodeling processes in hard periodontal tissues (decrease the level of calcium, magnesium and manganese against the background of increase the zinc content in cementum of tooth root; decrease the content of macroelements in alveolar process; activation of acid phosphatase against the background of inhibition of alkaline phosphatase activity). The development of combined endocrinopathy was accompanied by more pronounced changes of studied parameters.

Conclusions. The violation of glucose tolerance against the background of ID slows down the mineralization processes of hard periodontal tissues mainly due to the intensification of osteoresorptive processes.

Comprehensive Assessment of the Effectiveness of the Use of Alpha-lipoic Acid and Ipidacrine Hydrochloride for the Prevention of Paclitaxel-indused Peripheral Neuropathy in Breast Cancer Patients
Authors: Holotiuk Ivan , Holotiuk Serhii
Published: May 2023

Abstract. Almost 97% of women undergoing chemotherapy with paclitaxel for breast cancer suffer from symptoms of peripheral neuropathy, the severity of which directly depends on the single, cumulative dose and duration of infusion of the agent. Neurological manifestations of paclitaxel-induced peripheral neuropathy, such as bilateral numbness, neuropathic pain and paresthesias in the distal parts of the limbs, often lead to the need to reduce doses, up to the refusal of taxanes, which negatively affects the immediate and long-term results of treatment. Despite numerous scientific studies, there are no known means for prevention of chemotherapy-induced peripheral neuropathy. Of the more than 20 drugs studied so far for the prevention of chemotherapy-induced peripheral neuropathy, none has shown sustained and systemic clinically significant results.

The  aim of  the  study: to assess the effectiveness of the combination of alpha-lipoic acid and acetylcholinesterase inhibitor ipidacrine hydrochloride for the prevention of paclitaxel-induced peripheral neuropathy in breast cancer patients.

Materials  and  methods  of  the  study: a comprehensive assessment of clinical (survey regarding subjective symptoms and quality of life, neurological examination), neurophysiological (electroneuromyography) and morphological indices of paclitaxel-induced peripheral neuropathy in breast cancer patients who received polychemotherapy in neoadjuvant, adjuvant or palliative settings carried out according to the schemes of AT (paclitaxel, doxorubicin) or ET (paclitaxel, epirubicin) regimens with or without preventive treatment  of neuropathy, has been performed.

Results  of  the  study. The use of the studied scheme for the prevention of paclitaxel-induced peripheral neuropathy led to a significant improvement in neurological manifestations, neurophysiological and morphometric parameters of peripheral nerves, as well as quality of life and the severity of subjective symptoms and their impact on daily life activities in comparison with patients who received chemotherapy without treatment for the prevention of neuropathy.

Conclusions. The combination of alpha-lipoic acid and the acetylcholinesterase inhibitor - ipidacrine hydrochloride, could be recommended for prophylaxis of paclitaxel-induced peripheral neuropathy.

La familia influye en el desarrollo y bienestar personal, cuestión aún más notable durante la adolescencia. Bajo esta premisa, se busca analizar la satisfacción de 592 alumnos de Educación Secundaria Obligatoria con su ámbito familiar y vital. Para ello, se emplea la Family Satisfaction Scale y la Escala de Satisfacción Vital. Los resultados obtenidos son generalmente positivos, si bien manifiestan la necesidad de reforzar cuestiones como la flexibilidad, adaptabilidad y forma de abordar los conflictos en familia, así como de apoyar a quienes consideran no tener una buena vida, desean una distinta o perciben no tener todo lo que quieren.

This study aims to determine if high-voltage PRF could effectively adjunct epidural adhesiolysis (EA) in treating patients with chronic lumbosacral radiating pain (LSRP) and neuropathic characteristics. A total of 409 patients suffering from a single leg-radiating pain lasting for > six months and unresponsive to previous treatments were divided into three different groups: Group 1 consisted of 227 patients suffering from LSRP in lumbar stenosis, 84 treated with EA alone and 143 with PRF-EA; group 2 consisted of 99 patients suffering from LSRP in FBSS (Failed Back Surgery Syndrome), 24 treated with EA alone and 75 with PRF-EA; group 3 consisted of 83 patients suffering for LSRP in discal herniation, 20 treated with EA and 63 with PRF-EA. NRS evaluated the outcome at rest and in movement, SF-12 Physical and Mental Health Summary Scales, and present pain intensity scale (PPI), before the treatment and at the 1-month follow-up for all the patients included in the study. Descriptive statistics (mean ± SD) were reported for NRSrest, NRSmov, PPI, PCS, and MCS scores. A dependent sample T-test was used to compare pre and post-treatment outcome measures (NRS, PPI, PCS, MCS), in patients treated for discal herniation, FBSS and stenosis, respectively. A potential difference in outcome between the different procedures performed in the three groups (EA + PRF versus EA alone) was analyzed by applying an independent two-tailed t-test. P value less than 0.05 represented a significant difference. A significant reduction of radiating pain was observed at one-month follow-up in NRSrest and NRSmov, PPI scores, for all the three groups of patients, independently of the treatment adopted (p < 0.001). PCS12 and MCS12 significantly increased for all three groups of patients at 1-month follow-up (p < 0.001). No significant differences in outcome were detected for both procedures (EA vs. PRF-EA) in all three groups (p > 0.05). PRF and PRF-EA effectively reduce neuropathic pain intensity and improve the quality of life in patients who suffer from lumbosacral radiating pain in the context of lumbar stenosis, FBSS, or discal herniation. Adding pulsed radiofrequency (PRF) to epidural adhesiolysis alone does not improve the outcome.

Esta publicación tiene como objetivo reunir la investigación desarrollada en Brasil, específicamente en el estado de Bahía y en el Magdalena Medio colombiano, para avanzar en la búsqueda del mejoramiento de la productividad del sector cauchero. El cultivo de caucho (Hevea brasiliensis) en Colombia ha tenido un crecimiento vertiginoso en los últimos años, demostrado por las cifras actuales de área plantada que ascienden a 30.000 hectáreas (Censo Cauchero 2010), de las cuales el 17% se encuentra en producción y el 83% en desarrollo. Para la zona del Magdalena Medio el potencial de crecimiento es bastante amplio: en el 2010 se reportaron 7.000 hectáreas plantadas y con amplias posibilidades de expansión.

La mayor parte de la ganadería a nivel mundial se viene desarrollando en sistemas a campo abierto (sca) o monocultivos, la cual genera pérdidas económicas y ambientales, así como erosión de suelos, pérdida de biodiversidad de flora y fauna, baja producción de carne y leche, y menos ingresos monetarios. Frente a esta situación, existen alternativas sostenibles y sustentables de producción pecuaria que son amigables con el medioambiente, como los sistemas silvopastoriles (ssp). Por lo que, en esta revisión, se plantea analizar la sustentabilidad productiva de la instalación de ssp, al hacer un mayor énfasis en la composición florística de parcelas con ssp en Perú y Colombia, como estudio de caso. La revisión de información fue basada en la declaración Prisma, considerando criterios de inclusión y exclusión, se realizaron comparaciones de producción y calidad del pasto, productividad del ganado lechero y de engorde, oportunidades sociales y ambientales y la composición florística de tales ssp. La instalación de ssp incrementa los rendimientos productivos de los pastos (materia seca, digestibilidad y proteína) y de los animales, como mayor producción de leche y carne, y mayor biodiversidad de especies forrajeras. Además, en ambos países se observa que la implementación de estos sistemas ha mejorado las oportunidades para los productores dedicados a la ganadería, por los beneficiosos impactos económicos, ambientales y sociales que estos brindan. En ese sentido, es un reto para los científicos, gobiernos y entidades involucradas en sistemas sostenibles para seguir buscando nuevas alternativas viables y validarlas para la producción ganadera.

The purpose of this study was to identify the influence of physical and social vulnerability factors due to the eruption of Mount Merapi in Yogyakarta. Furthermore, this study identifies the significance of physical and social vulnerability to the achievement of the SDGs in Yogyakarta. The achievement of SDGs number 11 is supported by indicators of the percentage of the number of dead or missing victims to the total number of disaster events, disaster risk index, regional resilience index, number of resilient villages/kelurahan that have been formed, integrated early warning system, and availability of contingency plans. The achievement of SDGs number 13 is further explained using a simple indicator, namely greenhouse gas emissions. In this case, the research contribution is expected to add an indicator explaining the achievement of SDGs number 13 in addition to climate change. This study uses IRBI (Indonesian Disaster Risk Index) data to indicate the achievement of disaster risk reduction in the research area. The achievement of the SDGs, which has increased every year, certainly has positive implications for handling vulnerable groups. The location of this research study is the District of Turi. Turi sub-district is important to be studied considering the current conditions and potential future exposure to the eruption of Mount Merapi. This study utilizes the Analytical Hierarchy Process (AHP) technique to determine the weight of the indicators used in vulnerability modeling. The research data were tested using statistical analysis of data normality, probabilistic Poison, and the two-way ANOVA effect test. The results showed that there was no influence of the variables of physical vulnerability and social vulnerability on the existing SDGs. The conclusion of the research on the effect of physical and social vulnerability factors on the eruption of Mount Merapi Volcano shows that there is no influence of the value of physical and social vulnerability in Turi District on the achievement of SDGs in the form of the DIY Disaster Risk Index

Every city keeps growing as a result of population growth and has an impact on space requirements. Same as Banda Aceh City which continues to grow, but its development has stopped due to the 2004 tsunami disaster. Residential areas tend towards the north or the coast, which is tsunami-prone zone. The purpose of this study is to describe the direction and built-up area development of Banda Aceh City after the tsunami from 2005-2011, 2011-2015, and 2015-2020. The data used in this study is spatial data such as maps and satellite images sourced from Banda Aceh planning and development agency. Data analysis uses spatial approach with the overlay method. Development of the built-up area of Banda Aceh city based on the period 2005-2011, 2011-2015, and 2015-2020 shows that the built-up area leads to the northern and southern parts of Banda Aceh City. Development of the northern part of the city, Districts of Jaya Baru, Meuraksa, Kuta Raja, Kuta Alam, and Syiah Kuala was a result of the rehabilitation and reconstruction efforts such as housing, roads, and facilities after tsunami and turned the ponds and vacant land into housing and service trading areas. The northern part of Banda Aceh City was tsunami hazard-prone zone. Meanwhile, development of the southern part of the city, districts of Banda Raya, Lueng Bata, and Ulee Kareng, was influenced by Mohamad Hasan and Ali Hasyimi street which triggered the development of residential areas, office areas, service trading areas, and public facilities. Southern part of the city was not directly affected by the tsunami disaster. In addition, built-up area development has spread to the Aceh Besar regency.
