Published: February 2021

Pada minimarket, produk merupakan bahan pokok yang dijual belikan. Produk di minimarket terdapat antara produk yang laku dengan produk yang tidak laku. Dengan adanya masalah ini, perlu untuk menciptakan sistem yang dapat mengelompokkan produk laku dan produk yang tidak laku, yang dilakukan di Minimarket MM.TIKA Bengkulu dan dilaksanakan pada bulan Juni sampai Juli 2015. Algoritma K-Means tidak terpengaruh terhadap urutan objek yang digunakan, hal ini dibuktikan ketika penulis mencoba menentukan secara acak titik awal pusat cluster dari salah satu objek pada permulaan perhitungan. Jumlah keanggotaan cluster yang dihasilkan berjumlah sama ketika menggunakan objek yang lain sebagai titik awal pusat cluster tersebut. Namun, hal ini hanya berpengaruh pada jumlah iterasi yang dilakukan. Tujuan untuk membuat aplikasi dan menganalisis penjualan produk pada swalayan MM.TIKA Kota Bengkulu menggunakan metode K-Means. Dengan adanya sistem ini dapat memberikan manfaat kemudahan untuk menganalisis pengelompokkan penjualan produk pada swalayan MM.TIKA Kota Bengkulu, menentukan dan mengklasifikasikan penjualan produk yang laku dan kurang laku. Algoritma K-Means Cluster Analysis pada dasarnya dapat diterapkan pada permasalahan dalam memahami perilaku konsumen, mengidentifikasi peluang produk baru dipasaran dan algoritma K-Means ini juga dapat digunakan untuk meringkas objek dari jumlah besar sehingga lebih memudahkan untuk mendiskripsikan sifat-sifat atau karakteristik dari masing-masing kelompok. Metode yang digunakan pengumpulan data adalah observasi dan wawancara. Dengan adanya aplikasi ini, pemilik minimarket dapat melihat hasil pengelompokkan produk yang laku dan tidak laku. Maka, bila terdapat produk yang tidak laku, pemilik minimarket dapat mencari alternative lain agar produk yang tidak laku dapat menjadi laku. Kata Kunci : K-Means, Clustering, Data Mining, Produk

Kehidupan tidak terlepas dari hubungan antara manusia dengan Tuhan-Nya, salah satunya cara yaitu shalat sebagai rukun islam yang ke-2. Shalat merupakan satu hal yang wajib dilakukan bagi setiap umat Islam mulai dari baligh dan berakal. Dikarenakan pengaruh asing yang sangat masuk kedalam pemikiran budaya anak-anak, maka materi tentang shalat sangat disarankan dalam era globalisasi. Masalah yang ada saat ini, media yang digunakan masih bersifat konvensional. Siswa hanya bisa mendengarkan penjelasan dari guru saja. Hal tersebut terkadang membuat siswa merasa bosan dan malas untuk belajar karena tidak ada interaksi yang memberikan peran aktif kepada siswanya. Media pembelajaran ini menggunakan buku pembelajaran bergambar (yang dijadikan penanda untuk disimpan oleh smartphone, menjadi animasi 3 dimensi, 3D).

У статті проводиться аналіз багаторічної мінливості кліматичних факторів та водного режиму в межах зони впливу Південноукраїнського енергокомплексу. Для аналізу були використані ряди середньорічних, максимальних і мінімальних витрат води тривалістю до 2017 р. по водпостам Первомайськ (вище ПУЕК) та Олександрівка (нижче ПУЕК). Основні метеорологічні характеристики взяті по метеостанціям Первомайськ та Вознесенськ, оскільки вони розташовані найближче до зони впливу ПУЕК (вище та нижче). Для порівняння та кореляції даних з іншими періодами часу використано ряди метеорологічних показників за весь період спостережень, що проводяться з 1886 р.Відмічається, що останні декілька десятиліть характеризуються значними темпами потепління, як в цілому по території України, так і в регіоні розташування ПУЕК. На фоні загального підвищення кількості опадів в холодний період року і взагалі річної суми атмосферних опадів, проявилася тенденція досить значного зменшення кількості атмосферних опадів в липні-серпні, причому це зменшення супроводжується істотним підвищенням температури повітря на 5±2оС.Такі регіональні зміни клімату, в певній мірі, можуть стати причиною зменшення водності водойм, через збільшення випаровування при підвищення приземної температури та зменшенні кількості атмосферних опадів, особливо у верхів'ї та в середній частині басейну, а незначне підвищення кількості опадів в нижній частині басейну їх не компенсують (стік в цій частині басейну складає лише 17,5 % від річного стоку всієї річки). Формування водного режиму річки Південний Буг у районі розміщення ПУЕК, в останні десятиріччя відбувається на фоні позитивної фази коливань середньорічних температур повітря і негативної фази коливань опадів зимового сезону. Це призвело до суттєвого зменшення середньорічних витрат води р. Південний Буг на досліджувані території (по в/п Первомайськ на 20%, а по в/п Олександрівка – 30%).У стоці річки багатоводний період, який розпочався з кінця 60-х років минулого століття, з 2007 року змінився маловодним циклом. Сезонний перерозподіл стоку річки з даної території став менш вираженим протягом року. Істотно зменшився сток у весняний період, і збільшився в літній, осінній та зимовий.

Published: February 2021

The natural convection heat tranfer in annulate region confined between two homocentric cylinders were numerically studied in the present work. The annulus was filled by ethylene glycol / water based Titania nanofluid. Both internal and external cylinders are presereved at an isothermal hot and cold temperatures respectively, whereas, the upper and lower walls are adiabatic. The numerical solution is obtained by applying the finite volume method along with the SIMPLER, and TDMA algorithms. In the current study, the solid volumetric fraction is varied as (0 % ? ? ? 3 %), the volume ratios of EG to water are varied as (0:100 %, 40 : 60 %, 100:0 %), while both the Rayleigh number and radii ratio are considered fixed at (Ra = 104 and ? = 2). The obtained results indicated that, the average Nusselt number increases as the solid volumetric fraction and the volume ratio of ethylene glycol in the base fluid increase. Moreover, the velocity profiles reach their maximum value in the half region adjacent the internal hot wall when TiO2 – water nanofluid is used. Also, the temperature profiles decrease along the radial distance for all considered values of volume ratios of EG to water.
Hybrid system «layered magnesium silicate – chlorin е6 13(1),15(2),17(3)-N,N',N''-(2-hydroxyethyl)triamide»

Matrices based on layered silicates have a set of useful properties, in particular, they are able to increase the stability and photosensitizing ability of porphyrins. Hybrid systems “layered silicate - porphyrin (metal porphyrin)” are promising as active components of systems for light collecting and artificial photosynthesis, catalysts, photocatalysts. The hybrid systems with content of 1.4∙10-6 and 4.2∙10-6 mol of the chlorin e6 13(1),15(2),17(3)-N,N',N''-(2-hydroxyethyl)triamide per 1 g of layered magnesium silicate was obtained by heat treatment method of a synthetic layered magnesium silicate of hectorite composition when treated with an aqueous-alcoholic solution of organic component. The molar ratio of the starting components is: Mg(OH)2 : SiO2 : LiF = 1 : 1.51 : 0.25 : chlorin e6 derivative = 1 : 1.51 : 0.25 : (19.93∙10-5 – 59.58∙10-5). Using dynamic light scattering and laser Doppler electrophoresis, it was shown that the introduction of chlorin e6 13(1),15(2),17 (3)-N,N',N''- (2-hydroxyethyl) triamide leads to the growth of hybrid particles (162 ± 3 nm) and a decrease in their aggregative stability (-30 ± 1 mV), compared with the initial layered magnesium silicate (133 ± 1 nm, -33 ± 1 mV). In this case, the introduction of more hydrophilic chlorin e6 13(1),15(2),17(3)-N,N',N''-(2-hydroxyethyl)triamidе, in the molecule of which there are three fragments of ethanolamine, allows to obtain smaller hybrid particles (162 ± 3 nm), compared with hybrid particles (248 ± 6 nm) formed by the action of chlorin e6 13(1),17(3)-N,N'-(2-hydroxyethyl)diamide15(2)-methyl ether, in the molecule of which there are two fragments of ethanolamine. Using the methods of X-ray phase analysis and electron spectroscopy in the UV-visible region, it was found that individual molecules of chlorin e6 13(1),15(2),17(3)-N,N',N''-(2-hydroxyethyl)triamide were sorbed on the surface of silicate particles due to the electrostatic interaction between the protonated molecules of the macrocycle and the ionized hydroxyl groups of magnesium silicate. It was shown that the higher hydrophilicity of chlorin e6 13(1),15(2),17(3)-N,N',N''-(2-hydroxyethyl)triamide, compared with chlorin e6 13(1),17(3)-N,N'-(2-hydroxyethyl)diamide15(2)-methyl ether did not contribute to the intercalation of the organic component into the interlayer space of layered magnesium silicate under the conditions of a water-alcohol medium.

Production of high-quality food of animal origin directly depends on the health of farm animals. Feeding of farm animals balanced in terms of nutrients is the most important condition for improving the quality of livestock production and its productivity. The productivity of animals depends on providing their organisms with all the necessary nutrients and biologically active substances. Along with the nutritional value, chemical safety of feed is also important for animals and humans. Pesticides have a special place among chemical toxicants. The article presents the monitoring of the nutritional value and chemical safety of the main feeds of agricultural producers of the Republic of Tatarstan, based on the results of their physical and chemical studies carried out in 2019 by of "FCTRBS". The feed was tested for content of crude protein, moisture, crude fat, crude fiber, ash, and pesticides in accordance with the test methods included in the scope of accreditation of Test Center. 94.4% of feed for farm animals in the Republic of Tatarstan meet the requirements for nutritional value and chemical safety, which are imposed on them by the current regulatory and technical documentation. Only 5.6% of the studied feeds did not meet the physical and chemical parameters (the content of crude protein, crude fat, moisture, ash). A comprehensive assessment of the results of physical and chemical studies shows that agricultural feed producers in the Republic of Tatarstan comply with the basic requirements of the normative and technical documentation for the nutritional value and chemical safety of feed for farm animals. The latter determines not only the quality of animal husbandry, but also its efficiency and productivity.
Application of principal component analysis to the indicators of water exchange of triticale shoots under NaCl stress
Authors:   Tula State Lev Tolstoy Pedagogical University, Ivanishchev Viktor V.
Published: February 2021

The results of the study of the water regime characteristics (without and taking into account the indicators of oxidative stress) of triticale shoots under conditions of short-term NaCl stress were analyzed with the principal component analysis (PCA). It is shown that the water content is the most stable indicator of triticale shoots under experimental conditions. The results of the analysis led to the conclusion that its value is not determined by the value of stomatal conductivity and/or transpiration. Determination of the correlation coefficients between the studied characteristics yielded negative values between the water content and other indicators of the water regime, as well as oxidative stress, except for the value of lipid peroxidation (LPO) (0.67). Despite the closest relationship between the water content and the osmotic potential according to the results of cluster analysis, the correlation between them was negative (-0.76). This can be explained by different physiological and biochemical mechanisms that support each of these indicators. It is also shown that manifestations of oxidative stress are closely related to the osmotic potential and water content. In this case, the formation of a first-order cluster was observed between the content of water and hydrogen peroxide. This is not unexpected, but the correlation coefficient between them was only 0.018. This value can be interpreted in such a way that water is needed for the formation of hydrogen peroxide, but their quantitative ratio (water : hydrogen peroxide) in the shoots of triticale is significantly different. The inclusion in the analysis of the results of the accumulation of salt ions showed a closer relationship between the increase in the content of salt ions and the change in transpiration, stomatal conductivity and the content of proline than with the water content in the shoots of triticale under experimental conditions.

This paper presents the results of quantitative determination of cadmium and lead in milk, the quality of which is regulated by the Federal Law "Technical Regulations for Milk and Dairy Products" No. 88-FL of 12.06.2008, which indicates permissible levels of toxic substances in milk and basic dairy products. Cadmium and lead, as well as their compounds, are highly toxic substances of cumulative action and pose a serious danger to human and animal health, which makes regular monitoring of the content of these heavy metals in food, in particular milk, relevant. Eight samples of milk sold in the territory of the Chuvash Republic were selected as subjects of the study. Among them are six samples from popular shops of Cheboksara (trademarks “Just”, “Fresh tomorrow”, “From Krasuli”) and two samples of raw cow milk of private farms of Yadrin district (village of Grand Sundyr and village of Persirlana). The analysis of the crude, pasteurized and ultra heat-treated milk of various producers on the content of lead and cadmium at their joint presence was carried out by methods of an inversion voltamperometriya (GOST P 51301-99) and atomic and absorbing spectrometry (MU 01-19/47-11-92 “Methodical instructions by atomic and absorbing methods of definition of toxic elements in foodstuff”) and also in accordance with GOST 26932-96 “By raw materials and foodstuff. Lead Determination Methods” and GOST 26933-86 “Raw Materials and Food Products. Cadmium definition methods”. The minimum lead and cadmium content is found in “Just” brand milk samples of 0.0052±0.0016 and 0.0011±0.0013 mg/kg, respectively. The maximum lead content is found in samples of raw milk of Yadrin district (0.0262±0.0017 mg/kg), and cadmium – in milk of the manufacturer of the trademark “Just” from factory “Semisovsky” (0.0049±0.0007 mg/kg). It has been found that all the samples studied contain a very small amount of heavy metals, which does not exceed the MPC value, which makes it possible to highly assess the quality of milk and dairy products sold in Chuvashia.
Polysilazaoxanes and adhesive compositions based on them
Authors:   A.N. Nesmeyanov Institute of Organoelement Compounds  of RAS, Zachernyuk Alexander B.
Published: February 2021

The polymer formation proceeding with the participation of cardosilazaoxane organosilicon oligomers are considered. By the interaction of cardocyclic silazaoxanes with organosiloxane diols, new types of organosilicon oligomers are synthesized. They are capable to form elastic spatial-netted structures due to polymerization processes with the discovery of cyclic siloxane fragments without isolation of low molecular weight by-products. The influence of temperature and the silazaoxane: diol ratio on the nature of the products formed is studied. It was established that at 120-130 °C soluble oligomers of cyclolinear structure are formed, which are structured at 180-190 °C, with the most dense network structure being formed when the silazoxane: diol ratio is close to equimolar; a certain excess of hydroxyl groups at the final stage of polymerization leads to the association of the released ammonia with OH end groups and the formation of nucleophilic particles at the ends of the polymer chains – siloxanolate anions, possibly initiating structuring. The formation of regular three-dimensional structures – polysilazaoxanes, initiated by siloxanolate anions without the use of a special catalyst, is a new approach to the creation of adhesive compositions. In this case, in contrast to catalytically cured siloxane analogues, the resulting cross-linked polymer structures exhibit enhanced adhesion to the substrate material. Such polysilazaoxane oligomers can be used: a) as a basis for adhesives, only thermal effects and compounds containing siloxane films and coatings with various metals and characteristics can be used as a catalyst; b) for hydrophobic impregnation of textile materials and leather half-finished products, since this is clearly ammonia, which does not have a destructive effect on them.
Theoretical study of dimethylcarbonate production by urea alcoholysis
Authors:   Kazan National Research Technological University, Kurshev Nikita I.
Published: February 2021

Using the density functional method М06, the mechanisms of non-catalytic reactions of transesterification of urea with methanol with the formation of dimethyl carbonate, as well as in catalysis with zinc oxide and acetate, were studied. The transesterification proceeds stepwise with the intermediate formation of methyl carbamate. The non-catalytic process of transesterification of urea with methanol proceeds by the mechanism of nucleophilic SN2 substitution and is accompanied by the formation of pre-reaction complexes, which through synchronous transition states turn into post-reaction complexes, decomposing into ammonia and methyl carbamate in the first stage and dimethyl carbonate in the second. It has been established that methanol associates can take part in these reactions. Their participation is preferable both kinetically and thermodynamically. An analysis of the equilibrium constants of the reaction of urea with methanol at various temperatures showed that in a wide temperature range their values remain large in the first stage – the formation of methyl carbamate and become significantly reversible in the second – the conversion of methyl carbamate to dimethyl carbonate. Reactions involving acetate and zinc oxide proceed through the same stages as non-catalytic interactions. In the case of zinc acetate catalyzed reactions, if methanol monomer is involved in the reaction, the reaction of formation of methyl carbamate has a lower activation barrier compared to the reaction of conversion of methyl carbamate to dimethyl carbonate. If a methanol dimer is involved in the reaction, both reactions have a practically equal activation barrier. In the case of zinc oxide catalyzed interactions, reactions involving a methanol dimer were not detected. The participation of the catalyst leads to a significant decrease in activation barriers, and a more significant decrease occurs in the case of catalysis with zinc oxide. The reason for the different catalytic activity, in our opinion, is the difference in the charges on the urea carbon atom in the pre-reaction complexes.

Female sacrococcygeal pilonidal sinus features and EQ-5D life quality survey and body image survey results: a clinical study
Authors: SAYDAM Mehmet , ŞAHİN Mutlu
Published: February 2021

Aim: Pilonidal sinus disease (PSD) is not common in female patients. It is seen in adult women 2.2 to 4 times less than men. The most common age range is between 10 and 40. To date, there has been no randomized or retrospective study in the literature representing the general characteristics of women-specific pilonidal sinus cases and the quality of life questionnaire (EQ-5D) and body image questionnaire (BIQ) results. The purpose of this study is to show the general features, treatment principles and body image and quality of life (EQ-5D) survey results of the female pilonidal sinus cases.
Material and Method: A retrospective clinical study was conducted with 29 women who were admitted to our clinic between June 2013 and May 2016 and treated with surgery by the pre-diagnosis of sacrococcygeal PSD. Patients received face-to-face body image questionnaire (BIQ) and quality of life questionnaire (EQ-5D) at the 2nd postoperative week.
Results: The mean age was 27.07±5.63 years. BIQ cosmetic and self-confidence scores differ significantly between at least two groups (p=0.042 and p=0.021, respectively) in the favor of primer midline closure (PMC) group. As a result of bilateral comparisons made for the BIQ cosmetic score, there was a significant difference between the Limberg-Z plasty and the Karydakis group (p=0.039).
Conclusion: Female patients who underwent PMC had better satisfaction with the appearance of their scar. The treatment of female PSD with minimally invasive techniques and primary closure techniques seems to be the best option for the selected patients.

Authors: EKİZ İŞCANLI İnşa Gül , ŞAYLAN Bengü
Published: February 2021

Background: The disease SARS-CoV-2, which started in Wuhan city of China and caused pandemic, created an increasing number of intensive care needs due to its severe respiratory failure. The factors that determine the course of patients followed in intensive care are different. Therefore, our aim was to determine the factors that predict mortality and affect prognosis by evaluating the patients admitted to our intensive care unit.
Methods: This study is a single-center retrospective study involving 156 patients admitted to our Intensive Care Unit , who was diagnosed with SARS-COV-2 between 20 March and 8 June 2020. The data including characteristics, symptoms and laboratory findings of the patients were recorded and their relationships to mortality were evaluated
Results: The mean age was 69 ± 15 years and 63% were male. The most common symptom was dyspnea (69.9%) and fever (60,9 %), respectively. Comorbidity was present in 82% and the most common comorbidity was HT and DM, respectively. All patients were admitted to the intensive care unit with (due to) hypoxemic respiratory failure. 106 patients (68.8%) were connected to mechanical ventilation, which was associated with mortality (p <0.0001). High flow oxygen therapy was delivered in 31 patients and was associated with survival (p <0.05). Tozulizumab, given in addition to the treatments increased the survival (p<0.05).
Conclusion: We saw in our study that many parameters will be effective in predicting survival. As the most determining factors, not being intubated during admission and / or follow-up was observed to be effective on survival and was found to be associated with mortality.
Invasive home mechanical ventilation (I-HMV) experience at a palliative care center
Authors: KAHRAMAN Abdullah , CIRIK Mustafa Özgür
Published: February 2021

Aim: Although palliative care has recently become widespreadin the western countries, it has
not fitted on a solid base in our country yet. There is still no consensus on the admission criteria
to palliative care units. There is no widely used guidelines for the management of the patients
after invasive home mechanical ventilation (I-HMV).
In this study, we aimed to share our one-year clinical experience about the patients who were
transferred from intensive care unit (ICU) first to palliative care center then home with I-HMV.
The demographic and clinical data, education and discharge processes were evaluated.
Materials and Methods: The cases that used HMV used in the palliative care service between
July 2016 and September 2017 were retrospectively analyzed. The anesthesiologist was the
responsible physician of the palliative care center during this time period. The age, sex, primary
diagnosis and comorbidity of the patients were analyzed using statistical methods.
Results: Four patients (40%) were female and 6 (60%) were male, the mean age of thepatients
was 47,9 ± 16,39 years. Amyotrophic Lateral Sclerosis (ALS) was seen ın 4 patients and it was
the most commonly encountered indication for admission. The mean duration of stay in our
palliative care unit was 19,1±7,22days. The mean hospital stay was 19,1 days; the longest
hospitalization was 32 days and the shortest hospitalization was 9 days. Only 30% of the
patients have chronical disease Two (20%) patients had history of hypertension (HT), one (10%)
patient had chronic obstructive pulmonary disease (COPD).
Conclusion: The management of the critically ill patients with well coordination of intensive
care units and palliative care centers is a critical step to improve the quality of life scores for
patients were on I-HMV.
Corpus spongiosum abscess presented as new-onset diabetes in an adult patient: a case presentation
Authors: Celik Serhat , Öztekin Sanem , Kizilgul Muhammed
Published: February 2021

Rare infections, known as signal infections might be pathognomonic for patients with diabetes mellitus. A 55-year-old man without a significant medical history was admitted to our hospital with polyuria, polydipsia, dysuria, fever, chills and weight loss for the last month. A laboratory investigation showed leukocytosis and, elevated levels of C-reactive protein, sedimentation rate, blood glucose, and HbA1c. The patient was hospitalized in the internal medicine service and started intensive insulin therapy with intravenous saline infusion. The patient's fever and chills were not improved despite ceftriaxone treatment for three days. Ceftriaxone-resistant, imipenem-sensitive E. coli was grown in the blood cultures, so ceftriaxone was stopped and imipenem plus cilastatin combination was started. Detailed physical examination of the patient for fever etiology showed severe swelling in the perineal region. Superficial and scrotal ultrasonography and then pelvic magnetic resonance imaging revealed corpus spongiosum abscess. The perineal region was punctured and numerous Gram-negative bacilli and polymorphonuclear leukocytes were seen in the gram stain. Drainage catheter was inserted into the corpus spongiosum. Blood sugar levels were regulated and the patient was discharged after the antibiotic treatment was completed. As in our case, signal infections should be kept in mind especially in patients admitted with new onset of diabetes mellitus and persistent fever. A detailed physical examination should be performed in these patients and atypical areas like perineum should be carefully examined.
A rare Meckel’s diverticulum complication in inguinal hernia: case report of Littre hernia
Authors: Şenol Zafer , Gülşen Taygun
Published: February 2021

Abstract Meckel’s diverticulum (MD) is the most common congenital abnormality of the gastrointestinal tract resulted from incomplete closure of the omphalomesenteric tube between 5th-7th intrauterine week. The incidence of MD is reported to be around 2% in the general population. MD is generally asymptomatic during life and symptoms are observed in around 1% of patients. MD is rarely found within hernial sac which is known as Littre hernia (LH). The incidence of this extremely rare condition, LH, is less than 1% in all MD cases. It is difficult to diagnose LH preoperatively. A 63 years old male patient applied to our hospital with the complaints of swelling in both of his inguinal regions for the last six months. In the right hernia sac of the patient, Meckel’s diverticulum was seen which became evident during surgery. In this study, this very rare MD case observed and treated in our patient and known in the literature as a Littre hernia is presented.

A tökéletlen tökéletesség, avagy a Rendészettudományi szaklexikonnal kapcsolatos reflexiók margójára
Authors: Dános Valér
Published: February 2021

As one of the peer reviewers of the Law Enforcement Lexicon I state with full professional conviction that publication of this lexicon created a work of genre-historical importance for our law enforcement science reaching its teenage years. I would also like to record at the beginning of my reflection that I want neither praise nor blame this gigantic publication. In my notice I intend to stay impartial, objective and neutral even though I expressed my definitive recognition in the introducing sentence. This recognition means, according to my intention, rather thanks. So, I have to thank for the authors and editors as they gave a present to active contributors of law enforcement science, for people interested in it and for a wider reader public by this work appropriate to the present level of our law enforcement culture.
