Published: August 2022

This article discusses the egg breaking tradition carried out by the Javanese people who live in Sait Buttu Saribu Village, Simalungun Regency. The migration of the Javanese to East Sumatra in the 19th century, to work on plantations owned by Dutch businessmen, was accompanied by a shift in traditions and culture that they had practiced so far. This research uses qualitative research methods, with a cultural anthropological approach. This approach focuses on the view of life of a group of people in the form of behavior, beliefs, values and symbols that they inherit through the communication process from one generation to the next. After living for a long time in the Simalungun area, the Javanese people in this area still practice the egg breaking tradition, but it has been elaborated according to local culture. This tradition is usually carried out after the bride and groom carry out the marriage contract. In the procession, usually the bridegroom will step on a bamboo board under which is a raw egg. The foot used to step on the egg is the right foot, because the Javanese believe the right is a symbol of goodness

This article discusses the Islamization of ethnic Chinese in Medan City, 1961-1998. The entry of ethnic Chinese in Medan City has a different time span and two waves have occurred. The first wave began when the Chinese trade fleet came to visit the port and conducted trade relations, then the second wave when the Dutch needed workers engaged in plantations. In this study using historical methods. The procedures that have been implemented in this study are heuristics (collection of sources), verification (historical criticism), interpretation, and historiography. The Islamization of Chinese ethnics in the city of Medan is due to the belief that occurs in someone who wants to embrace Islam, not because of coercion that must be faced. This belief is attended by a special interest in getting to know Islamic teachings after comparing them with the teachings of other religions. In addition, because of the calm and comfort that is felt after embracing Islam.

Published: August 2022

This article discusses the scorched earth tragedy that occurred in Pangkalan Brandan during the Indonesian independence revolution. Pangkalan Brandan is an area that is included in the territory of the Sultanate of Langkat. Before being managed by a foreign company, the oil mines in this area were managed by the local community in a traditional way. However, after the discovery of new oil wells in Telaga Said and Telaga Tunggal by the Dutch East Indies company Koninklijke Nederlandsche Maatschappij tot Exploitatie van Petroleumbronnen in Nederlandsch Indie, the management of Brandan petroleum was managed in a modern way. This study uses the historical method in four writing steps, namely; heuristics, verification or criticism, interpretation, and historiography, based on library research related to the topic under study. At the end of the Dutch East Indies rule, the Brandan petroleum mine was burned by the Dutch due to the imminent arrival of Japanese troops. Then after being controlled by Indonesia, there was another scorching of the Pangkalan Brandan oil refinery carried out by fighters and the surrounding community. This terrible tragedy is still celebrated as the "Scorched Earth Pangakalan Brandan" event.

This article discusses the influence of foreign cultures on the existence of Malay music in Medan City in the period 1970-2000. The arrival of various foreign communities in Medan City also brings their original culture. The acculturation of foreign communities with ethnic Malays produces a beautiful blend of cultures. This study uses the historical method in four writing steps, namely; heuristics, verification or criticism, interpretation, and historiography, with a cultural approach. Ethnic Malay as an egalitarian society can accept foreign culture with open arms. The interaction of the Malay people for hundreds with foreign cultures has brought significant changes to their culture. This can be seen from the various musical genres that influence Malay music. In addition, the use of musical instruments from various foreign cultures also enriches the treasures of Malay music. Even though it was influenced a lot from foreign cultures, Malay music still survives and exists today.

This article uses the historical method with four steps, namely: heuristics, criticism, interpretation, and historiography. The main focus of this article is to see the history, development, and practice of the tarekat. This congregation was founded by Caliph Ahmad Idris in 1937 AD. After studying Sufism for a long time in Besilam Village, Langkat, under the direct care of Sheikh Abdul Wahab Rokan. After that he was appointed by Sheikh Abdul Wahab Rokan to establish and disseminate the Naqsyabandiyah Tarekat in their respective hometowns. This tarekat is now managed by a third descendant named Caliph Saipul Abdi. Currently, the tarekat is still carrying out my usual Suluk activities, even though the number of congregations is decreasing. The unique thing about this tarekat is that there is never a haul (death anniversary) from its leaders. As the leadership admits, this is sometimes the reason why this tarekat is less popular than other tarekat around the Labuhanbatu Regency area.

Published: August 2022

This article discusses the history and development of the Bilah Sultanate which is currently located in Labuhanbatu Regency. This sultanate is one of the influential sultanates in the East Sumatra region, especially Labuhanbatu. This sultanate became the conquered territory of the Siak Indrapura Sultanate which was supported by the Dutch. This article uses a historical research method with four steps, namely: heuristics, criticism, interpretation, and historiography. The author's data collection was done by directly visiting the locations of the former areas of the Bilah Sultanate, interviews with traditional leaders and descendants, as well as written data from archives, books, journals and so on. The results showed that the Sultanate of Bilah had a period of prosperity as a result of its cooperation with the Dutch Colonial. Plantation investments made by European businessmen in the Labuhanbatu region and its surroundings were the reason this sultanate became so prosperous. However, because of its proximity, the Sultanate of Bilah also became a victim of the ferocity of the anti-feudalism (social revolution) movement in 1946 which targeted the Malay aristocrats in East Sumatra. The tragedy marked the end of the existence of the Blade Sultanate in the Labuhanbatu region.

Key Points

Combining unique genetic and surgical models, we demonstrate that both renal and systemic sources contribute to angiotensin-converting enzyme 2 (ACE2) detected in the urine in angiotensin II–mediated hypertension.

Micropuncture coupled with nanoproteomics confirm detection of ACE2 in early glomerular filtrate obtained from Bowman’s capsule in mice.

Kidney-derived ACE2 and soluble ACE2 may be useful clinical targets in kidney disease.

Background

ACE2 is a key enzyme in the renin-angiotensin system (RAS) capable of balancing the RAS by metabolizing angiotensin II (AngII). First described in cardiac tissue, abundance of ACE2 is highest in the kidney, and it is also expressed in several extrarenal tissues. Previously, we reported an association between enhanced susceptibility to hypertension and elevated renal AngII levels in global ACE2-knockout mice.

Methods

To examine the effect of ACE2 expressed in the kidney, relative to extrarenal expression, on the development of hypertension, we used a kidney crosstransplantation strategy with ACE2-KO and WT mice. In this model, both native kidneys are removed and renal function is provided entirely by the transplanted kidney, such that four experimental groups with restricted ACE2 expression are generated: WT→WT (WT), KO→WT (KidneyKO), WT→KO (SystemicKO), and KO→KO (TotalKO). Additionally, we used nanoscale mass spectrometry–based proteomics to identify ACE2 fragments in early glomerular filtrate of mice.

Results

Although significant differences in BP were not detected, a major finding of our study is that shed or soluble ACE2 (sACE2) was present in urine of KidneyKO mice that lack renal ACE2 expression. Detection of sACE2 in the urine of KidneyKO mice during AngII-mediated hypertension suggests that sACE2 originating from extrarenal tissues can reach the kidney and be excreted in urine. To confirm glomerular filtration of ACE2, we used micropuncture and nanoscale proteomics to detect peptides derived from ACE2 in the Bowman’s space.

Conclusions

Our findings suggest that both systemic and renal tissues may contribute to sACE2 in urine, identifying the kidney as a major site for ACE2 actions. Moreover, filtration of sACE2 into the lumen of the nephron may contribute to the pathophysiology of kidney diseases characterized by disruption of the glomerular filtration barrier.

Features of the calculation of air leaks through the mined-out space of coal mines
Authors: Minieiev S. , Novikov L. , Samopalenko P. , Makarenko R.
Published: August 2022

The movement of air leaks through the goaf of coal mines can lead to gas contamination of workings with the formation of local and layer accumulations of methane. This increases the likelihood of explosive situations. Therefore, an important factor is the ventilation scheme used in the excavation area. The process of gas flow through a goaf is an understudied issue. This is due to the difficulty of conducting direct measurements inside the object under study. In many works, when studying the movement of air leaks through the mined-out space, the linear Darcy filtration law is used. However, the influence of inertia forces can lead to additional gas pressure losses and, accordingly, to deviations from the classical law. Therefore, it is advisable to use the law of two-term filtration. The purpose of the work is to study the patterns of movement of air leaks through the mined-out space, taking into account its filtration parameters and the current ventilation scheme. The article presents the results of calculating the speeds of air leaks and the trajectories of streamlines in the mined-out space with direct-flow and return ventilation schemes. The Darcy formula and the Forchheimer formula were used in the calculations. It has been established that with a two-term filtration law, the values of the result-ing air leakage rates are less than with a linear law. This is due to pressure losses as a result of inertial forces. It has been established that with a direct-flow ventilation scheme, the rates of air leakage in the longwall increase exponentially along the goaf boundary in the direction of the ventilation flow and quadratic ally increase deep into the goaf to a certain maximum located at a distance of about half the length of the longwall. At the same time, in the case of the return-flow ventilation scheme, the rates of air leaks in the longwall have maxima at the boundary of the goaf and decrease linearly towards the center of the longwall, and in the goaf at a distance of up to three meters from the longwall, their quadratic decrease occurs. The results obtained make it possible to reduce the gas contamination of workings by choosing rational schemes and ventilation modes.

History of the Badagas in the Novel "Kurinjitthen"
Authors: S Ramesh
Published: August 2022

Rajam Krishnan's fiction "Kurinjitthen" describes the lives of three generations of the Badagas ethnic community who migrated from the state of Karnataka after the tenth century AD. Through this novel, the cultural elements of three generations of the Badagas community are shared. It can be seen that the attachment of the first generation to the land is diminishing in the succeeding generations. Later, their culture was also mixed due to foreign contact. People who live in a materialistic society are greedy for money and start cultivating tea in their land. The Kurinji flower land is occupied by the tea plants. Rajam Krishnan constructs the struggle between old and new in fiction through characters. Time creates the environment for the next generation to accept the change. In this novel, Rajam Krishnan has written everything about the life, culture, change of time, and generation gap of Badagas. The core of the story is a tender love specific to the land of Kurinji and its disappointment. The literary space of Rajam Krishnan is also explored through this novel.
"Outcast" as Indicated in Tamil Literature
Authors: M Anu
Published: August 2022

During the Sangam period, Tamil Nadu flourished in all fields like literature, art, civilization, and politics. It is the Sangam literature that helps us to understand that famous society. That literature is full of historical sources, biographical events of the people, and internal and external events. The superiority of a country is determined by the lifestyles of its people. The literature that appeared in each period indicates the lifestyles of the people who lived in that period. The Sangam period, hailed as the golden age in the history of Tamil Nadu, had many special features. The Sangam literature that appeared at that time was also considered the cultural treasury of the people. It is also possible to clearly understand the lifestyles of the people of that time as described in the literature. There are ups and downs in the lives of the people of this era, where there is a lot of pride and fame. Tolkappiyam belongs to the early period of Tamil literary history. Both the studies of agathinai (internal life) and the genetics of Tolkaapiyam provide some information about the Varna system (sub divisions). The agathinai came to talk about the study of dividing them into four categories, namely king, noble, merchant, and servant. All these four are mentioned as "Eval Marapinar" (Commanding Lineage). That is, from Nachinarkinyar's explanation that "the business of inciting others is their own," it is clear that there was a section in society that obeyed the incitement of the four clans. This research paper tries to investigate the literature saying that the people who are engaged in this search are outcasts, their professional method, and the Varna (class) system of that time.

The purpose of this article is to analyze the elements used in the teaching of classes at the Universidad Tecnológica del Norte de Aguascalientes (UTNA), seeking to develop a reflection in relation to the pieces that students consider necessary for effective learning and understanding of the topics of study. Living conditions, the customs, the particular characteristics of a sector of the population or geographic area, and the use of new technologies have as a consequence that the study models and the techniques or tools that young people use for the development of their education suffer continuous changes. Consequently, to believe or expect that the elements of the development of a class should be standardized, remain inert, and also, ensure the understanding and continuous interest of young people is too ambitious; This is why the main point is to obtain the vision that young people have of the elements they consider necessary for effective learning in the classroom.

Background: Quercetin has antioxidant and anti-inflammatory effects. Although there are previous animal experi-ments investigating Quercetin’s effect on ischemia reperfusion (IR) injury in the literature, studies involving effect of lower extremity IR on remote organ are rare.Materials and Methods: 18 male Wistar Albino rats were randomly divided into 3 groups, 6 in each group as; Cont-rol (C), Ischemia-reperfusion (IR), IR-Quercetin, (IR-Q). Their weights were between 200-250 g. 30 minutes before the procedure20 mg/kgQuercetin was administered via intraperitoneal route. In the IR groups, infrarenal abdomi-nal aorta was clamped by an atraumatic microvascular clamp. After 120 minutes of ischemia and reperfusion was achieved for another 120 minutes. When reperfusion period ended, tissue samples were taken from the lungs. Malondialdehyde (MDA) level, superoxide dismutase (SOD) and catalase (CAT) enzyme activity and histopathological parameters were compared.Results: We found the MDA level in the IR group higher than the control group (p<0.0001). Lower MDA level was found in the IR-Q group compared tothe IR group (p=0.012). SOD and CAT enzyme activity in the IR group was notably lower in the control group (p<0.0001, p<0.001, respectively). Higher SOD and CAT enzyme activities were found in the IR-Q group compared to the IR group (p=0.012, p<0.001, respectively). Neutrophil infiltra-tion/aggregation, alveolar wall thickness and total lung injury score were notably higher in IR group than in C group (p=0.001, p=0.002, p<0.0001, respectively). In addition, a statistically significant decrease was observed in the Quercetin treated group in neutrophil infiltration/aggregation, alveolar wall thickness and total lung injury score compared to the IR group (p=0.023, p=0.022, p=0.002, respectively).Conclusions: We determined that intraperitoneally administered Quercetin at a dose of 20 mg/kg30 minutes before ischemia in rats reduces lipid peroxidation, oxidative stress and reduces the damage caused by IR in lung histo-pathology.Study findings suggest that Quercetin has a lung protective effect when administered before IR.

The aim of this preliminary research was the evaluation of a two-month program for improvement of single forward feint to the left with passage to the right, and single forward feint to the right with passage to the left by „shifting opponents” hand. Sixteen young male handball players, aged 9.64 ± 0.87 years, participated in this study. The program was being implemented in two months, in which 18 training sessions (35%) were conducted for the improvement of feint skills, from 52 training sessions overall. Initial video recording was accomplished at the beginning of the period, and final video recording at the end. Videos were analyzed by three experts, using grading list and detailed grading criteria. The basic parameters of descriptive statistics were determined for both variables. The metric characteristics of the expert estimation contribution were analysed through measures of reliability (Cronbach's α) and homogeneity (average item intercorrelation). The non - parametric (Wilcoxon t-test) method was used to analyse changes in the levels of feint performance at different time points. The results indicate satisfactory reliability and homogeneity of the tests (α1=0.90; r1=0.80; α2 =0.86; r2=0.87). By insight into results, the significant difference is spotted between the initial and final state of both motor skills acquisition (T1 = 114.5, p= 0.01; T2 =7.00; p= 0.01). The limiting factors can be seen in the sample size of this entity, the absence of the control group as well as the validated evaluation of the instrument.

: El presente artículo tiene como objetivo reportar los hallazgos de una investigación sobre músicas urbanas desarrolladas en la Región de Los Lagos. Presentamos los antecedentes socioculturales que dan cuenta de la instalación de un movimiento musical mapuche williche en la región. El proceso de análisis nos permitió determinar la emergencia de elementos musicales que pueden ser entendidos como significantes potencialmente tópicos. Como resultado de esto encontramos la existencia de un tópico musical que hemos denominado “mapuche en resistencia”, el cual se construye en torno a ítems musicales que presentan el uso de la trutruka o que incorporan alusiones miméticas a este instrumento. Para finalizar, reflexionamos sobre las proyecciones del estudio en materia de descentralización de los saberes etnomusicológicos en Chile, así como del potencial de otras formas de investigación social como métodos complementarios en la disciplina.

This study aims to present the application of remote sensing in monitoring vegetation change in Binh Duong Province, Vietnam. The study used Landsat 5 images in the year 2010 and Landsat 8 images in the years 2015 and 2020 to investigate the area of vegetation. The maximum likelihood classification method (MLC) was used to classify land cover and an accuracy matrix was computed to validate the classification results. The references data were collected to support classification and accuracy assessment processes including land use maps in 2010, 2015, and 2020. In addition, collected field points and UAV (unmanned aerial vehicle) in 2020 were used. The overall accuracies are 81.27%, 84.41%, and 83.86%, and Kappa indices were 0.76, 0.80, and 0.80, corresponding to 2010, 2015, and 2020. The results showed that as compared to 2010 and 2015, the area of vegetation in 2020 decreased 10% and 8%, respectively. The average vegetation cover per capita was 740 m2 person-1 in 2020, compared to 1000 m2 person-1 in 2015 and 1200 m2 person-1 in 2010. This reduction was obvious in urban areas in the province, due to the need for construction and development. The study provides meaningful information on vegetation change and green area per capita in Binh Duong Province from 2010 to 2020.

Population growth and the increasingly rapid industrial technology to 4.0. So that there was an electric car with an electric motor as the driving force. At first, electric cars used a DC motor system. But the triumph of this DC motor is not long in coming because problems arise when compared to induction motors such as complicated maintenance, much higher prices, and heavier weight than induction motors. In an induction motor, the control is believed to be easier than a DC motor. The induction motor is believed to make it possible to drive an electric car. The advantage of using this induction motor is that it has durability, reliability, if exposed to interference, it remains strong, easy to maintain, and the ability to operate in extreme environments. These advantages can replace the use of DC motors. Where the induction motor receives power from a rechargeable battery, so that the analysis of data from an induction motor for an electric car with the calculation of the electric motor rotation is 1,500 rpm, the motor power itself is 375 kW, the maximum and minimum torque generated is 582 Nm and 271 , 2 Nm, with a battery life of 189.3 hours. The resulting acceleration to reach speeds of 0-100 km / h only takes 5 seconds.

The purpose of this research is to improve the performance of the disc friction welding machine that has been built and is operated, but there is a drawback, namely that there is no measuring device for process parameters such as rotational speed and forging load. In addition, during operation there is a vibration of 1.5 mm / s to 4.9 mm / s which is unacceptable according to ISO-2372 standards, so that these deficiencies can affect the quality of weld production. Repair or modification of this the friction welding machine is carried out by selecting and installing a rotating speed sensor (RPM) and load cell forging loads and installing rubber to dampen vibrations. Furthermore, the function test was carried out with the load, it was obtained that the rotational speed read on the LCD was 3.7% greater than the tachometer and the vibration decreased up to a value of 0.9 mm/s where this value was acceptable according to ISO-2372, while the performance test resulted in welding production for 3 workpieces with plate sheet material AA-110, ASTM A36 and CU-DHP copper with the same thickness, namely 1mm. From the results of the specimen tensile test of the three materials, it was found that the breakdown location was in the welding area where the tensile test value was around 1.2 to 5.1% of the tensile value of the workpiece material.

Process control is needed in various types of industries for production. The controlled process variables can be temperature, flow, pressure, and level. For this reason, an automatic control system with the right method is needed to produce quality products. This study aims to design and implement a steam pressure control system on a prototype heating tank using PID controller based on PLC. The pressure in the heating tank will be controlled to a set point of 10 kPa with a maximum steady-state error of 3%. PID control is designed using the Ziegler Nichols method which is then implemented on the PLC Omron CP1H with an MPX5500DP sensor to detect pressure. The results of the research obtained are that the PI controller can produce a better response when compared to the P and PID controllers. PI controller with parameters Kp = 1.23, Ti = 860, and Td = 0 can produce a response with a rise time of about 300 seconds and a steady-state error of 3.3%.
