Clinicopathological Study of Extranodal Marginal Zone Lymphoma in a Tertiary Care Centre in North Kerala
Authors: Kannadas Shima , Kunnaruvath Rajeevan
Published: March 2021

BACKGROUND Extranodal marginal zone lymphomas are rare groups of B cell lymphomas that arise in mucosa associated lymphoid tissues of various sites. Strong association with autoimmunity and certain infections are its distinct features. Diagnosis is by histology with immunophenotyping alongside ruling out other low-grade lymphomas. In this study we wanted to analyse MALTomas with regard to their clinical features, relation to autoimmunity, histological and immunohistochemical profile. METHODS This is a descriptive study conducted from 2013 to 2018 at a tertiary care centre in North Kerala. Study sample included all cases of extranodal lymphomas obtained retrospectively from 2013 to 2017 and prospectively from 2017 to 2018. Blocks of all specimens were cut and stained with haematoxylin and eosin (H & E) and immunohistochemical markers. RESULTS Out of the 15 cases we analysed, the most common sites of involvement were gastrointestinal tract (40 %) followed by thyroid (27 %). Thyroid, which is a rarer site for MALT lymphoma, is detected as one of the frequent sites in this study. In our study, stomach was one of the less common site affected which is in contrast to other studies. Associated autoimmune disorder was detected in 20 % of cases. 46 % of cases show features of transformation to high grade lymphoma. CONCLUSIONS This study analysed the features of MALT lymphomas in different sites and found a strong association with autoimmune disorders. Rarer sites like thyroid were found to be more frequently involved and common sites like stomach was detected in only small percentage of cases. Although most cases are indolent low-grade lymphomas, possibility of transformation to a high-grade B cell lymphoma should always be considered when dealing with these cases. Utility of immunohistochemistry in ruling out other small cell lymphomas is also well demonstrated in this study.

Association of Serum Telomerase Activity in Type 2 Diabetes Mellitus Patients with or without Microalbuminuria
Authors: Rattan Roma , Lamare Andrew Abel , Jena Sudeep , Sahoo Nirmal , Mandal Manmath Kumar
Published: March 2021

BACKGROUND Telomerase is an enzyme which helps in maintaining the length of the telomeres. Various studies have associated the telomere length and serum telomerase activity with ageing, insulin resistance and obesity. The metabolic disease type 2 diabetes mellitus is also associated with premature ageing, obesity, insulin resistance. Urine microalbuminuria is one of the frequently used markers to assess renal involvement in non-insulin dependent type 2 diabetes patients. Hence, this study was conducted to estimate the association of serum telomerase activity, a marker of aging and its association with urine microalbuminuria in non-insulin dependent type 2 diabetes patients with or without renal involvement. METHODS The study included 180 non-insulin dependent type 2 diabetes patients divided into two groups – Group I without microalbuminuria; Group II with microalbuminuria and 90 age and sex matched healthy volunteers as control population of the study. The sample size was determined at conveniences. Fasting blood sugar, lipid profile, serum urea, creatinine was estimated by autoanalyser, glycated haemoglobin by high performance liquid chromatography (HPLC) and serum telomerase activity were measured by enzyme-linked immunosorbent assay (ELISA) method. Urinary microalbuminuria was measured by immunoturbidimetry. The data was compared by one-way analysis of variance (ANOVA) and post hoc Tukey’s honestly significant difference (HSD) test, linear regression analysis and Pearson correlation analysis. RESULTS Non-insulin dependent type 2 diabetes patients with microalbuminuria had significantly lower telomerase activity and higher glycated haemoglobin, dyslipidaemia, increased serum urea and creatinine levels as compared to the group I diabetes mellitus patients and healthy volunteers. The serum telomerase level exhibited a negative correlation with urinary microalbuminuria, glycated hemoglobin and serum triglyceride and BMI. CONCLUSIONS Low Serum Telomerase is associated with microalbuminuria, obesity and poor glycaemic control in non-insulin dependent type 2 diabetes mellitus patients, indicating the possible existence of a common clinical profile and premature aging among diabetic patients with chronic kidney disease. Early screening for microalbuminuria and serum telomerase level may assist management of positive cases and reduce the load of chronic renal disease and coronary artery disease in type 2 diabetes patients. Validation of our observations may be done by extending the study in larger population thereby facilitating the understanding of T2DM pathophysiology and its complications.

Authors: S Prakash , G Ramamoorthy , R Shankar
Published: March 2021

BACKGROUND Organo phosphorous compound poisoning is one of the most common suicidal poisonings in India. The various clinical entities that determine the clinical course and outcome in the ICU of OPC poisoning patient are type of the compound and dose of poison. Delayed presentation and multi-organ failure are some of the major factors that decide the outcome of the patient. This study was conducted to assess the clinical outcome of patients with OPC poisoning on assisted ventilation and assess the various factors that determine the outcome. METHODS A prospective observational study was conducted for a period of 6 months at a government tertiary care hospital in Chennai. All patients with history and clinical signs of OPC poisoning requiring mechanical ventilation for respiratory support were included as our study subjects. Outcome of patients was measured in terms of either recovery or death and factors influencing the outcome such as type of OPC compound, amount consumed, onset and duration of respiratory muscle weakness and pseudocholinesterase levels were considered. RESULTS In the 172 subjects, 108 (62.7 %) patients were successfully extubated from mechanical ventilator and 64 (37.2 %) patients expired. Patients aged more than 40 years, patients who consumed methyl parathion with quantity of poison more than 50 ml, patients with serum cholinesterase levels less than 500, patients who were atropinised for more than 3 days and who were on mechanical ventilation for more than 3 days were the factors found to have a statistically significant association (P < .05) for causing death among patients with OPC poisoning. CONCLUSIONS The mortality among the OPC poisoning patients who were on mechanical ventilation was found to be very high. Early resuscitation of patients with OPC poisoning might reduce the morbidity and mortality. KEYWORDS Organo-Phosphorous Compound Poisoning, Mechanical Ventilation, Clinical Outcome

Authors:   Lawyer at International Trade and Integration Limited Liability Company, Antonova Darya Yu.
Published: March 2021

In the WTO a risk assessment is a mechanism of maintaining a balance between the interests of international trade and the protection of human life and health. In the course of the study, the author concludes that despite a historically different understanding of risk assessment, at present most SPS disputes are considered through the prism of this mechanism. At the same time, the author notes that there is no sufficient risk assessment recognition in the DSB practice. The author marks a practical importance of this article for risk-based approaches in Russia.

Published: March 2021

The availability of consumer credit has led to the spread of debt obligations in modern Russia. Most families during marriage manage to acquire not only assets in the form of property rights, but also liabilities in the form of debt obligations. The issue of the legal regime of such debts during marriage has been resolved by the legislator, but the fate of the spouses’ common obligations in the event of a judicial division of property remains unresolved. The article discusses the emerging approaches to the regulation of common debt obligations in the case of the division of common property of spouses.

Ukrainian Migration Aspirations towards Germany: Analysis and Development Scenarios
Authors: Boiko Vitalii , Mulska Olha , Baranyak Ihor , Levytska Olha
Published: March 2021

Based on the multiple regression model and scenario approach to forecasting, the article estimates the Ukrainian migration aspirations towards Germany (the scale of migration, the economic activity of migrants, and their economic benefits). It is argued that major transformations in the gender-age structure of the German population may cause a demographic crisis and labour market imbalances. Our projections indicate the growing role of foreign human resources in the German economy. When modeling the scale of emigration from Ukraine, an integrated approach is applied, considering not only trends of pull-push factors but also special aspects of the German migration policy and the outflow of 8–10 million Ukrainian migrant workers. Given the poor statistical data on the scale of labour emigration needed for constructing reliable econometric models, the use of expert forecasting method remains the most optimal technique for assessing potential migration flows and migration systems.

Published: March 2021

The article attempts to develop a methodology for a comparative assessment of the economic efficiency of banks, including traditional and Islamic banking models. The assessment shows that the stability of financial institutions in Azerbaijan is lower compared to banks where Islamic banking is used. The assessment also shows that there is a strong dependence of the GDP growth rate on the sub-indices of the effectiveness of financial institutions in Azerbaijan, Turkey, and Iran. The methodology of linear regression and a composite index of the economic efficiency of banks are applied. The assessment shows that the influence of the stability of the financial system on economic growth in Azerbaijan, Iran, and Turkey is different. The economic growth rate and the ratio of bank loans to bank deposits in Azerbaijan and Turkey are positively related, but negatively in Iran.

Authors: Zaborski D. , Grzesiak W.
Published: March 2021

The present study is planned to apply boosted classification trees for the detection of cows with potential conception problems. Nine hundred and eighteen artificial insemination records from Polish Holstein-Friesian Black-and-White cows were included. Each record consisted of nine predictor variables. The output variable was a conception difficulty class (good or poor). Sensitivity, specificity and accuracy on the test set were 82.93%, 84.46% and 83.91%, respectively. The most influential predictors of conception difficulty included calving interval, gestation length, body condition score, fat and protein content and age. Boosted classification trees could be applied as an on-farm decision support tool to identify cows with conception problems.
Variability in Value of Health in Social Fields: Challenges and Incentives for Self-Care Practices
Authors: Berdysheva Elena , Belyavskiy Boris
Published: March 2021

Strong motivation to selfcare is assumed by design of contemporary healthcare policy. However, both western and Russian studies show motivational deficit and inattention to prevention care among population. Actual paper examines the problem of motivation as a relational choice. Opposing to the view on motivation as a part of individual will, we consider motivation as a choice between competing requirements to selfcare among multiple social fields. We collected 27 in-depth interviews with Russians from large cities and analyzed them in abductive logic. In the analysis we focused on health practices performed in the fields of family and career. The results demonstrate that individuals succeed in selfcare when the care of health appears essential for execution of important social roles.

Spatial development of the Russian Far East: demographic and socio-economic factors
Authors: Makar Svetlana , Yarasheva Aziza , Simagin Yury
Published: March 2021

The article presents analysis of the trends in the demographic development of the regions of the Russian Far East and the processes that directly and indirectly determine preservation of the human potential of the macroregion. Multidimensional analysis allows us to assess the objective opportunities for successful development of both the macroregion as a whole and its separate territories, including those within the framework of the current State national programs. The dynamics of population in combination with its low density and shortage of labor resources significantly affect the socio-economic development of the regions in the district. Socio-demographic indicators (migration balance, healthy life expectancy, share of citizens adhering to a healthy lifestyle) and socio-economic indicators (dynamics of monetary income / consumer spending and investment in fixed assets per capita) allowed us to identify the main trends of recent years in the development of the Far East regions. It was found out that the majority of regions belong to the most depopulating territories in Russia with critical indicators of the level of self-preservation behavior, with the current dangerous trend of migration losses (primarily in the working-age population), with low values of the life expectancy index. It is necessary to conduct a differentiated economic policy in the macroregion. The characteristics of differentiation of the situation in the macroregion, shown in the article, may contribute to development of a set of tools to deal with the situation in each region of the Far East. Since the main cause of the unfavorable demographic trends is the lag of the real living standards of the population behind the national average, the necessary measures of administrative action are: financing of social infrastructure in the macroregion; ensuring high social standards for families of professionals; providing a competitive level of education and conditions for development of the system of training and retention of personnel; effective functioning of regional economic clusters; development of small and medium-sized businesses.

Published: March 2021

The article was prepared on the results of a study of the impact of urban environment quality (UEQ) on the demographic characteristics of city dwellers (birth and death rates, ageing index, birth-death ratio). These demographic indicators, in the authors' opinion, can reflect to a certain extent the state of population health. More comprehensive data on the Russian urban population health (life expectancy at birth, primary disease incidence by main disease classes, disability, etc.) are not published by Rosstat. This article is the first to set the task of assessing the impact of urban environment quality on city dwellers health through the urban environment quality index developed by specialists from the RF Ministry of Construction and other organizations in 2018. The study was carried out in 174 cities of the Russian Federation with a population of over 100 thousand people. The cities were grouped according to the following criteria: UEQ index, population size, belonging to Federal Districts. The strength of relationship was estimated by Spearmen rank correlation coefficient, the reliability of the obtained results was checked by scatterplot and Pearson correlation coefficient. Comparison of the city groups was made using nonparametric analysis of variance. To check the differences between the groups of cities, the Kruskal-Wallis test by ranks was implemented.

Published: March 2021

Among the key goals of the National Project «Healthcare» is provision of state (municipal) medical organizations with qualified medical personnel. This issue has become especially acute in the context of the unfolding fight against the new coronavirus infection. The achievement of the targets set in the National Project largely depends on the quality of training of medical personnel. Meanwhile, noticeable changes have been taking place in the system of medical education in recent years: in the regulatory and legal framework of medical and educational activities, technical equipment and conditions of economic activity of universities, etc. The changing socio-economic context leaves an imprint both on those entering universities, their motivation, and those who train future doctors. The second part of the article continues the presentation of the results of the study «Development of human resources in the capital's health care» carried out in 2019, which concerns both the quantitative aspects of the staffing of medical organizations subordinate to the city, and the quality of medical personnel related to their professional training. Information about the quality of graduates of medical universities and the factors determining it was obtained through a series of in-depth structured interviews with experts, who were representatives of the capital's medical universities and chief doctors of medical institutions. During the survey, the experts expressed their opinion on the organization and content of the educational process, as well as on the problems related to introduction of professional standards, changes in educational programs, emergence of new academic disciplines, technical equipment (including simulators) of educational institutions. Analysis of the expert opinions testifies to the ambiguity of the situation in Russian medical education. It reveals the need for additional study of the issues of expediency of availability, volume (in hours) and distribution of academic disciplines by stages of the educational cycle in medical universities. A serious negative aspect, highlighted by the experts, is still the low level of practical experience, the lack of which sharply reduces the quality of medical education in general.
Impact of intergenerational transfers on fertility
Authors: Babyshev Vyacheslav
Published: March 2021

On the theoretical basis of the "generational economy" the article describes the "model of overlapping generations" and "life cycle model" as the cause of the existence of intergenerational transfers. The classification of approaches to their study is carried out. Based on the exchange model (the concept of childbearing as a long-term investment in future transfers from adult children to elderly parents) and the theory of substitutions (crowding out private transfers by public social systems), the "elderly security hypothesis" is highlighted as a possible socio-economic reason for the demographic transition. Based on the works of A. Cigno, a theoretical review of this theory is made using the concepts of ^substitution effect» and «free rider effect». According to the works of R. Fenge and B. Scheubel, the "income effect" and "price effect" are defined as the key parameters for testing this hypothesis. An overview of the existing scientific and practical works on the topic of research is made, highlighting methods and results on the following examples: Italy after World War II, Germany at the turn of the 19th and 20th centuries, Brazil in 1991-2000, Hungary in 19502006, 34 OECD countries in the 1990s and the consolidated data for 121 countries at present. The author has carried out his own empirical test of the «hypothesis of elderly security» in the countries of the world on the basis of UN and OECD statistics. Coverage, social security spending, replacement rate, mandatory premium rate, and an increased risk of poverty among older people support the safe aging theory of upward intergenerational transfers from children to parents. But the internal rate of return of pension systems and the average income of older people support the competing hypothesis of top-down intergenerational transfers from parent to child. It is concluded that, with a relatively low standard of living of population, intergenerational transfers go from children to parents, but when a certain level of national welfare is reached, the movement of transfers changes to the opposite direction.
Rural population dependence on the level of agricultural development: panel data analysis of Leningrad oblast

Published: March 2021

Rural development has been and remains a relevant government task. Dynamic structural and technological changes in the agricultural sector lead to the need of reassessing the mutual influence of the level of development of agricultural production and rural areas. The study deals with quantitative assessment of the dependence of rural population size as an integral indicator of socio-economic well-being of rural areas on selected factors and indicators that characterize the level of agricultural development, its sectoral specifics and the structure of agricultural producers. Empirical estimates were obtained from panel data of municipal districts in Leningrad oblast for 2012-2018. The greatest positive impact on the rural population size among the considered characteristics of agriculture is determined for the factor of sown areas that is associated with the specifics of agricultural sub-sectors, their different needs for such factors as land and labor, the development potential for small-scale farming. It was found that the concentration of agricultural production in the large commercial sector has a negative impact on the rural population size. This is explained by difference in employment dynamics and redistribution of resources between categories of agricultural producers. Modeling results showed that agrarian subsidies received by agricultural producers have a statistically insignificant impact on rural population that justifies the need to adjust the orientation and forms of agricultural state support to achieve a synergetic effect on rural development.

“MENOS DIREITOS E EMPREGO OU TODOS OS DIREITOS E DESEMPREGO”: A “UBERIZAÇÃO” DO TRABALHO NO BRASIL NO DISCURSO PRESIDENCIAL
Authors: ALMEIDA JOÃO PAULO MARTINS DE
Published: March 2021

Neste trabalho, considerando as declarações de Jair Bolsonaro a respeito da situação dos/as trabalhadores/as no Brasil, são analisadas as formas como o discurso do mandatário reflete o discurso de mercado que promove o empreendedorismo e a “uberização” do mundo do trabalho, isto é, a desregulamentação de leis trabalhistas que tornam as ocupações laborais mais precárias. Tendo em conta as contribuições teóricas de Michel Pêcheux (2014) a respeito do processo discursivo, entendendo-o como inscrito numa relação de classes, intenta-se realizar a análise das condições de produção do discurso em consonância a Courtine (2016), que as compreende como as condições históricas que determinam a produção das materialidades discursivas. Dessa forma, procura-se demonstrar como o discurso de mercado, que rege a lógica de negócios da Uber, está se expandindo para vários setores da atividade laboral – no Brasil e no mundo.

Effect of Lipids and Lipoproteins on Hematopoietic Cell Metabolism and Commitment in Atherosclerosis
Authors: Baragetti Andrea , Bonacina Fabrizia , Catapano Alberico Luigi , Norata Giuseppe Danilo
Published: March 2021

Hematopoiesis is the process that leads to multiple leukocyte lineage generation within the bone marrow. This process is maintained through-out life thanks to a nonstochastic division of hematopoietic stem cells (HSCs), where during each division, one daughter cell retains pluripotency while the other differentiates into a restricted multipotent progenitor (MPP) that converts into mature, committed circulating cell. This process is tightly regulated at the level of cellular metabolism and the shift from anaerobic glycolysis, typical of quiescent HSC, to oxidative metabolism fosters HSCs proliferation and commitment. Systemic and local factors influencing metabolism alter HSCs balance under pathological conditions, with chronic metabolic and inflammatory diseases driving HSCs commitment toward activated blood immune cell subsets. This is the case of atherosclerosis, where impaired systemic lipid metabolism affects HSCs epigenetics that reflects into increased differentiation toward activated circulating subsets.

Aim of this review is to discuss the impact of lipids and lipoproteins on HSCs pathophysiology, with a focus on the molecular mechanisms influencing cellular metabolism. A better understanding of these aspects will shed light on innovative strategies to target atherosclerosis-associated inflammation.
The Cosmological OTOC: A New Proposal for Quantifying Auto-correlated Random Non-chaotic Primordial Fluctuations
Authors: Choudhury Sayantan
Published: March 2021

The underlying physical concept of computing out-of-time-ordered correlation (OTOC) is a significant new tool within the framework of quantum field theory, which now-a-days is treated as a measure of random fluctuations. In this paper, by following the canonical quantization technique we demonstrate a computational method to quantify the two different types of Cosmological auto-correlated OTO functions during the epoch when the non-equilibrium features dominates in Primordial Cosmology. In this formulation, two distinct dynamical time scales are involved to define the quantum mechanical operators arising from cosmological perturbation scenario. We have provided detailed explanation regarding the necessity of this new formalism to quantify any random events generated from quantum fluctuations in Primordial Cosmology. We have performed an elaborative computation for the two types of two-point and four-point auto-correlated OTO functions in terms of the cosmological perturbation field variables and its canonically conjugate momenta to quantify random auto-correlations in the non-equilibrium regime. For both the cases we found significantly distinguishable non-chaotic, but random behaviour in the OTO auto-correlations, which was not pointed before in this type of studies. Finally, we have also demonstrated the classical limiting behaviour of the mentioned two types of auto-correlated OTOC functions from the thermally weighted phase space averaged Poisson Brackets, which we found exactly matches with the large time limiting behaviour of the auto-correlations in the super-horizon regime of the cosmological scalar mode fluctuation.
Hybrid Classical-Quantum Fitting Attention States to Statistical Mechanics of Neocortical Interactions
Authors: Ingber Lester
Published: March 2021

Hybrid Classical-Quantum computing has already arrived at several commercial quantum computers, offered to researchers and businesses. Here, application is made to a classical-quantum model of human neocortex, Statistical Mechanics of Neocortical Interactions (SMNI), which has had its applications published in many papers since 1981. However, this project only uses Classical (super-)computers. Since 2015, a path-integral algorithm, PATHINT, used previously to accurately describe several systems in several disciplines, has been generalized from 1 dimension to N dimensions, and from classical to quantum systems, qPATHINT. Published papers have described the use of qPATHINT to neocortical interactions and financial options. The classical space described by SMNI applies nonlinear nonequilibrium multivariate statistical mechanics to synaptic neuronal interactions, while the quantum space described by qPATHINT applies synaptic contributions from Ca2+ waves generated by astrocytes at tripartite neuron-astrocyte-neuron sites. Previous SMNI publications since 2013 have calculated the astrocyte Ca2+ wave synaptic interactions from a closed-form (analytic) expression derived by the Principal Investigator (PI). However, more realistic random shocks to the Ca2+ waves from ions entering and leaving these wave packets should be included using qPATHINT between electroencephalographic (EEG) measurements which decohere the quantum wave packets. This current project extends calculations to multiple scales of interaction between classical events and expectations over the Ca2+ quantum processes to include these random shocks in previous codes used to fit EEG data to the SMNI model, that included the analytic forms for the quantum processes but now replaced by qPATHINT. The PI's Adaptive Simulated Annealing (ASA) importance-sampling optimization code is used for fitting the combined classical-quantum system. Gaussian Quadratures is used for numerical calculation of momenta expectations of the astrocyte processes that contribute to SMNI synaptic interactions. This project thereby demonstrates how some hybrid classical-quantum systems may be calculated quite well using only classical (super-)computers.

The present study investigated the effect of art on promoting the meaning of the urban space. In this regard, after considering the semantic dimension of the urban space and the mechanism of transferring the meanings of art through the views of experts, a model is presented for examin-ing the art’s cooperation in promoting urban space meaning in Tehran. In this study, a mixed method was used. In the first stage, the categories of space meanings influenced by art were ex-tracted through using the qualitative method of interpretive phenomenology and by examining 61 in-depth interviews in six urban spaces eligible for urban art in Tehran. In the second stage, these categories were surveyed in these spaces through 600 questionnaires after converting to the questionnaire items. Based on the results, "the possibility of the experience and perception", "social participation", and "the relationship with the context" were the main themes of the se-mantic relationship of art and urban space. Further, the lower scores related to the theme of "so-cial participation" in the quantitative investigations indicated that this theme was weaker than the other themes in promoting the meaning of the urban space through the art in the selected urban spaces.

Kota Surakarta merupakan salah satu kota di Jawa Tengah yang perkembangannya paling pesat. Dengan perkembangan yang demikian pesat, maka Kota Surakarta merupakan salah satu kota dengan pusat kegiatan perekonomian, perdagangan, pendidikan, kebudayaan, dan sektor informal lainnya. Keadaan ini di satu sisi menimbulkan masalah tempat tinggal bagi masyarakat tetapi di sisi lain merupakan peluang bagi kalangan developer atau pengembang untuk menyediakan sarana hunian dengan membangun apartemen yang dibutuhkan. Di sisi lain, karena perkembangan di berbagai sektor tersebut termasuk sektor investasi, banyak masyarakat yang memilih untuk berinvestasi dibidang properti di Surakarta yaitu dengan membeli apartemen lalu disewakan atau mengharapkan kenaikan harga yang signifikan saat mereka nanti menjualnya. Oleh karena itu, tujuan penelitian ini adalah untuk mengetahui preferensi masyarakat dalam memilih apartemen dan mengetahui faktor yang paling mempengaruhi preferensi masyarakat dalam memilih apartemen di Kota Surakarta. Untuk itu, perlu dilakukan penelitian terkait preferensi masyarakat dalam memilih apartemen. Dalam penelitian ini digunakan metode Fuzzy Analytical Hierarchy Process (F-AHP) dengan bantuan software Microsoft Excel 2013. Data didapatkan dengan cara menyebar kuisioner kepada pemilik maupun penyewa dari 3 apartemen tinjauan yang telah ditentukan. Dari hasil penelitian didapatkan bahwa faktor yang paling mempengaruhi masyarakat dalam memilih apartemen yaitu faktor legalitas.

Published: March 2021

Endapan seruakan piroklastik (pyroclastics surge) seringkali berasosiasi dengan erupsi preatomagmatik dan  preatik yang banyak melibatkan adanya air permukaan dan bawah permukaan. Di Indonesia, endapan pyroclastics surge yang sudah teridentifikasi salah satunya berada di lereng Gunungapi Lamongan. Penelitian ini memiliki tujuan untuk mengetahui karakteristik mineralogi dari tanah endapan jenis tersebut, selain itu juga bisa untuk mengetahui proses mekanisme pengendapan yang terjadi pada saat pembentukan material ini. Metode yang digunakan dalam penelitian ini adalah pemetaan geologi daerah penelitian,pengamatan fisik makroskopik, kemudian dilakukan analisis petrografi dan SEM EDX untuk mengetahui komposisi mineraloginya sekaligus untuk mengetahui tipe erupsi maupun mekanisme pengendapannya.

Kondisi geologi di daerah penelitian mempunyai morfologi pegunungan dan perbukitan vulkanik berlereng terjal, litologinya dominan tersusun  oleh endapan vulkanik hasil erupsi Gunungapi Lamongan dengan jenis batuan andesit, basalt, serta  endapan hasil letusan maar. Komposisi mineralogi batuan penyusunnya berdasarkan analisis petrografis dan SEM-EDX didominasi oleh plagioklas tipe andesin, ortopiroksen hipersten, dan klinopiroksen augit sebagai fenokris, serta untuk massa dasarnya tersusun oleh mikrolit plagioklas, mineral opak (magnetit), dan gelas vulkanik.

Tipe erupsi pembentuk maar atau ranu di sekitar Gunungapi Lamongan adalah jenis freatomagmatik, dibuktikan dari kenampakan fisik dan struktur batuannya yang mengindikasikan adanya pengaruh air yang signifikan dan aliran berdensitas rendah.

At this time the government prohibits the use of antibiotics in animal feed as a growth promoter (AGP) or antibiotic, so an effective and safe immunomodulator and herbal growth stimulant product are needed through Meniran extract products (Phyllantus niruri) and chemicals in the market are not yet optimal as immunomodulators and growth stimulants. CV. Maxipro Agrosatwa which is engaged in veterinary medicine, wholesale trade of agricultural products, and other live animals will produce feed using Meniran extract products. Extraction equipment that is needed is a Rotary vacuum evaporator. This equipment is needed to separate the solvent from the solute without high heating which will damage the solute content. The vacuum condition in the flask is to make the separation more efficient as well as accelerate the separation of the solvent from a solution by reducing the boiling point. The rotation of the flask is to increase evaporation. The complexity of this equipment is what makes CV. Maxipro Agrosatwa cannot handle it alone and requires technical assistance from the Department of Mechanical Engineering (JTM) FT UNS. Technical assistance provided by JTM FT UNS is in the form of procurement, delivery, installation, operation, and maintenance of the rotary vacuum evaporator.

Natural fiber reinforced composites is one materials potentially developing in Indonesia. One of biggest problem with composites specimen is its void. One properties to find out void of composites is composites density value. The objective of research is to investigate the effect of fiber alkali (NaOH) treatment and microcrystalline cellulose (MCC) addition on density value of cantala fiber reinforced unsaturated polyester composites. Firstly, cantala fibers was submerged into alkali (NaOH) 6% solution for 0, 3, 6, 9, and 12 hours. Furthermore, the fiber was washed using acetid acid and then using clean water to reach pH 7. Thereafter, cantala fiber was dried in the oven for 10 hours at temperature 600C. Composites was composed of cantala fiber, unsaturated polyester polymer matrix, and microcrystalline cellulose according to the composition with volume fraction 30%. Composites was casted using compression molding method with compressive strength of 10 MPa for 12 hours. All specimens of composites undertake post cure for 2 hours at 600C. Density test was conducted using densimeter by calculating the density of composites in the air and the water. The result of research showed that the longer the alkali treatment time and the more addition of microcrystalline cellulose (MCC) filler, the higher is the composites density. The higher density value of cantala fiber reinforced unsaturated polyester is alkali treatment 6 hours, which was 1.223 gr/cm3.
