Impor pupuk dilakukan untuk memenuhi kebutuhan kebutuhan pupuk. Penelitian ini bertujuan untuk menganalisis pengaruh PDB dan nilai tukar sebagai determinan impor pupuk di Indonesia. Lokasinya berada di Indonesia, dengan periode penelitian 2004 hingga 2018. Data yang digunakan adalah data time series yang terdiri dari data nilai tukar, PDB, dan impor pupuk. Sumber data dalam penelitian ini adalah data yang dipublikasikan pada Statistik Ekonomi Keuangan Indonesia (SEKI). Laporan Statistik Kementerian Perdagangan dan laporan statistik perdagangan luar negeri untuk impor Indonesia dari publikasi Badan Pusat Statistik (BPS). Penelitian ini menggunakan metode ordinary least square (OLS) dengan analisis regresi linier berganda sebagai persamaannya. Kondisi impor pupuk di Indonesia cenderung menunjukkan fluktuatif. Namun, dalam beberapa tahun terakhir telah menunjukkan peningkatan. Secara bersamaan, PDB Indonesia dan nilai tukar mempengaruhi impor pupuk Indonesia. Namun secara parsial, impor pupuk Indonesia dipengaruhi secara positif dan signifikan oleh PDB. Sedangkan nilai tukar tidak berpengaruh signifikan terhadap impor pupuk Indonesia. Fertilizer imports are carried out to meet fertilizer needs. This study analyzes the effect of GDP and the exchange rate as determinants of fertilizer imports in Indonesia. The location is in Indonesia, with a research period from 2004 to 2018. The data used is time series data consisting of data on exchange rates, GDP, and fertilizer imports. The data source in this study is the data published in the Indonesian Financial Economic Statistics (SEKI). The Ministry of Trade's Statistical Report and foreign trade statistical reports for Indonesian imports from the publication of the Central Statistics Agency (BPS). This study uses the Ordinary Least Square (OLS) method with multiple linear regression analysis as the equation. Fertilizer import conditions in Indonesia tend to fluctuate. However, in recent years it has shown improvement. Simultaneously, Indonesia's GDP and the exchange rate affect Indonesia's fertilizer imports. However, partially, Indonesia's fertilizer imports are positively and significantly affected by GDP. Meanwhile, the exchange rate does not have a significant effect on Indonesia's fertilizer imports.

An important role in the development of acne is played by the activity of the skin microflora (namely the bacteria Propionibacterum acnes) and members of the genus Staphylococcus. In the schemes of complex treatment of patients with this disease, antibiotics from among macrolides or lincosamides are mainly used. It is of interest to study the current state of susceptibility of staphylococci and propionic bacteria to these drugs, as well as to other antimicrobial agents in order to determine the prospects for expanding the arsenal of methods for treating acne. The aim of the study was to study the susceptibility of microorganisms involved in the development of acne to antimicrobials and antagonistic effects of probiotic strains of lactobacilli. We conducted a bacteriological study of the content of rash elements in 60 patients with acne. The biological characteristics of 40 strains of Staphylococcus spp. and 15 strains of Propionibacterum acnes isolated and researched. The sensitivity of microorganisms to antibiotics and antiseptics was determined by the disco-diffusion method and the method of serial double dilutions of drugs in a liquid nutrient medium. Determination of the sensitivity of acne pathogens to the antagonistic effect of lactobacilli was performed by the method of two-layer agar by reducing the number of microorganisms. The results of the study made it possible to establish that the isolated strains of bacteria show a low level of sensitivity to antimicrobials, which in medical practice are most often used for topical therapy of acne. Only 17.5 % of isolated staphylococcal strains were sensitive to erythromycin, only 45.0 % of strains of this species were sensitive to clindamycin. Strains of Propionibacterum acnes showed a higher level of sensitivity to antibiotics than staphylococci. However, the established indicators do not allow to consider highly effective means for treatment of acne on their basis. At the same time, a high level of sensitivity of acne pathogens to antiseptic drugs decamethoxine and Aeroplysinin 1 and antagonistic effect of Lactobacillus acidophilus was established. Thus, the strains of Propionibacterum acnes and Staphylococcus spp., involved in the development of acne, are characterized by high levels of resistance to erythromycin, clindamycin, chloramphenicol, benzoyl peroxide, which are now the basis of the arsenal of topical therapy for patients with this disease. There is a need to find new effective drugs for the etiotropic therapy of acne.

SEFER hA MINAGIM, p. 574 (photo 1), on behalf of an older book, writes that according to Jewish tradition, the navel does not close completely after childbirth, but remains partially open to extract various infections from the body. "From the "greenness" called "gable- zaht" (דזשאָנדַאַס איז קרענק די – disease jaundice), he will take a male pigeon for a man, and a dove for a woman; and put it on the navel, and the pigeon (dove), having drained all the infection from it (the patient), will die. Well-known veterinarian, Dr. Yekutiel Sharabi, owner of an elite veterinary clinic in Northern Tel Aviv, studied the causes of pigeon death after such a session. He found that immediately after treatment with pigeons, the patient's blood bilirubin level decreases by 25%, and recovery lasts an average of 3 days (as opposed to 28 days with conventional treatment). Autopsies of pigeons that died after the session showed liver enlargement and dysfunction. If the session was applied to a healthy person, not a single pigeon died. [1]
In this paper, we consider a heuristic method for using quantum teleportation protocols in convergent dualuse biotechnologies based on new physical principles of operation [1-80]. The features of these biotechnologies will be considered within the framework of the possibilities of convalescence of pathological conditions (for example, nosological form: liver damage (lat. jecur, jecor, hepar, etc. - Greek ἧπαρ) by the hepatitis "C" virus (non-A, non-B hepatitis, or NANBH, or HCV infection). A hypothetical convalescence technology can be implemented by preparing cascades of entangled states of biological objects. In fact, this paper implies a certain information exchange in the planet's biogeosphere, hypotheses, protocols, and schemes for implementing these mechanisms based on new physical principles of action (NFP) [1-80].

Published: June 2021

The problem of estimating the level of air pollution in the working areas near the coal pile is considered. The task is to develop a CFD model that allows to predict the level of air dust pollution, taking into account the process of wetting the surface of the coal pile. To model the process of coal dust transfer in the air, a twodimensional mass transfer equation is used, which takes into account coal dust transfer due to convection and diffusion. The Navier-Stokes equations are used to calculate the air flow field near the coal pile. Finite-difference schemes of splitting are used for numerical integration of modeling equations.
Computer code is developed on the basis of created CFD model. The developed code can be used to analyze the effectiveness of the coal surface wetting to reduce dust pollution of work areas near coal piles. The results of a computational experiment are presented.

A különleges mentési felszerelések biztonságos használatának elemzése statisztikai módszerekkel : I. rész
Authors: Jackovics Péter 
Published: June 2021

A katasztrófák és a balesetek fokozódó extrémitása miatt a mentési műveletek egyre összetettebbé váltak, ez pedig mind elméleti mind pedig gyakorlati szempontból jobbanfelkészült mentési szakszemélyzetet kíván meg. Komoly problémát jelent, hogy a különleges mentéseknél alkalmazott eszközök használatának módszerei sok esetben csupán „szájhagyomány” alapján terjednek, miközben a gyártók által a kifejlesztett eszközpark viszont dinamikusan fejlődik. A mentési felszerelések ilyen mértékű változása a kötéltechnikával végzett mentések esetében is jól megfigyelhető, ahol a biztonságos eszközhasználatnak fokozottan kell érvényesülni.A tanulmány célja, hogy egy erre a célra tervezett kérdőíves kutatás eredményeinek matematikai statisztikai feldolgozása alapján egyfelől megválaszolja azt a kérdést, hogy a felhasználók hogyan ítélik meg három kiválasztott konkrét kötéltechnikai eszköz biztonságos használhatóságát, másrészt pedig erre támaszkodva biztonságnövelő javaslatokat fogalmazzon meg ezen eszközök használatával kapcsolatban. A tanulmányom első részében a Mann-Whitney próba és a Spearman-féle rangkorreláció eredményeit elemzem.

The purpose of this study was to explore the effects of integrating meaning-centered positive education (MCPE) and the second wave positive psychology (PP2.0) into a university English speaking class. The study adopted Wong’s CasMac model of PP2.0 and designed a series of English lessons which aimed to understand the meaning of life through the perspectives of PP2.0 and its focus on MCPE. The participants were 38 university students, with upper-intermediate English proficiency, enrolled in an English speaking class. They participated in the English program for 15 weeks and 2 h each week. The quantitative data was collected from survey of the CasMac Measure of Character and analyzed with the pairedt-test method, and the qualitative data analysis was collected from students’ weekly learning sheets and journals. The results show that the integration of MCPE and PP2.0 in a university English class is feasible to enhance students’ understanding of mature happiness through the CasMac model and to promote their meanings in life. According to the research findings, it is suggested that the CasMac model can be applied to other fields or other groups who need help to enhance life meaning and improve wellbeing. Particularly under the pandemic of COVID-19, there are people encountering traumas, losses, and sorrows and it is crucial to transform sufferings with the support of approaching mature happiness.

PurposeTo extract texture features from magnetic resonance imaging (MRI) scans of patients with brain tumors and use them to train a classification model for supporting an early diagnosis.MethodsTwo groups of regions (control and tumor) were selected from MRI scans of 40 patients with meningioma or glioma. These regions were analyzed to obtain texture features. Statistical analysis was conducted using SPSS (version 20.0), including the Shapiro–Wilk test and Wilcoxon signed-rank test, which were used to test significant differences in each feature between the tumor and healthy regions. T-distributed stochastic neighbor embedding (t-SNE) was used to visualize the data distribution so as to avoid tumor selection bias. The Gini impurity index in random forests (RFs) was used to select the top five out of all features. Based on the five features, three classification models were built respectively with three machine learning classifiers: RF, support vector machine (SVM), and back propagation (BP) neural network.ResultsSixteen of the 25 features were significantly different between the tumor and healthy areas. Through the Gini impurity index in RFs, standard deviation, first-order moment, variance, third-order absolute moment, and third-order central moment were selected to build the classification model. The classification model trained using the SVM classifier achieved the best performance, with sensitivity, specificity, and area under the curve of 94.04%, 92.3%, and 0.932, respectively.ConclusionTexture analysis with an SVM classifier can help differentiate between brain tumor and healthy areas with high speed and accuracy, which would facilitate its clinical application.
Identification of Methylation-Regulated Differentially Expressed Genes and Related Pathways in Hepatocellular Carcinoma: A Study Based on TCGA Database and Bioinformatics Analysis
Authors: Liang Yu , Ma Bin , Jiang Peng , Yang Hong-Mei 
Published: June 2021

BackgroundIn recent years, DNA methylation modification has been shown to be a critical mechanism in the field of epigenetics.MethodsHepatocellular carcinoma (HCC) data were obtained from The Cancer Genome Atlas project, including RNA expression profiles, Illumina Human Methylation 450K BeadChip data, clinical information, and pathological features. Then, differentially expressed genes (DEGs) and differentially methylated genes were identified using R software. Methylation-regulated DEGs (MeDEGs) were further analyzed using Spearman’s correlation analysis. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed using the DAVID database and ClueGO in Cytoscape software. Kaplan–Meier survival analysis explored the relationship between methylation, expression of MeDEGs, and survival time. Gene set enrichment analysis (GSEA) was conducted to predict the function of prognosis-related MeDEGs.ResultsA total of nine up-regulated and 72 down-regulated MeDEGs were identified. GO and KEGG pathway analyses results indicated that multiple cancer-related terms were enriched. Kaplan–Meier survival analysis showed that the methylation status of four MeDEGs (CTF1, FZD8, PDK4, and ZNF334) was negatively associated with overall survival. Moreover, the methylation status of CDF1 and PDK4 was identified as an independent prognostic factor. According to GSEA, hypermethylation of prognosis-related MeDEGs was enriched in pathways that included “Spliceosome”, “Cell cycle”, “RNA degradation”, “RNA polymerase”, “DNA replication”, “Mismatch repair”, “Base excision repair”, “Nucleotide excision repair”, “Homologous recombination”, “Protein export”, and “Pyrimidine metabolism”.ConclusionsAberrant DNA methylation plays a critical role in malignant progression of HCC. Prognosis-related MeDEGs identified in this research may be potential biomarkers and targets in diagnosis and treatment.
