Authors: Stephan Barbara , Zinner Herbert , Kastner Fritz , Mannschreck Albrecht
Published: February 2022

As a first case in the field of spirochromenes, the energy barrier for thermally reversible ring opening of 2,2'-spirobichromenes (Scheme) is measured by racemization of preparatively enriched enantiomers. In addition, this barrier is estimated via racemization during HPLC (Fig.) on tribenzoylcellulose without preparative enrichment. The significance of the latter procedure is discussed.
Nevv Reactions of Vinylindoles as Heterocyclic Dienes with 4-Phenyl-1,2,4-triazoline-3,5-dione: Non-Concerted versus Concerted Processes
Authors: Pindur Ulf , Kim Myung-Hwa
Published: February 2022

The reactions of some 3-vinylindoles and one 2-vinylindole with 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) were investigated. In dependence on the structure of the vinylindole, the experimental results revealed the occurrence in some cases of a non-concerted step to furnish Michael-type
adducts and in other cases of a probably concerted Diels-Alder reaction to furnish novel pyridazino[b]indoles, respectively. In one particular case, PTAD-catalysed dimerisation of the 3-vinylindole took place.
Micellar Composition Affects Lipid Accretion Kinetics in Molecular Dynamics Simulations
Authors: Kahana Amit , Lancet Doron , Palmai Zoltan
Published: February 2022

Mixed lipid micelles were proposed to facilitate the emergence of life through their documented growth dynamics and catalytic properties. Our research predicted that micellar self-reproduction is possible through composition-driven catalyzed accretion of lipid molecules in heterogeneous systems, reaching states that allow micellar growth and split while maintaining compositional homeostasis. However, experimentally studying catalyzed accretion in mixed micelles is technically challenging. Here, we employ atomistic Molecular Dynamics simulations to examine the self-assembly of variegated lipid assemblies allowing us to derive entry and exit rates of monomeric lipids into pre-micelles with different compositions. We observe considerable selective rate-modifications that are compositionally-driven, and illustrate their underlying mechanisms as well as the energy contributions that facilitate these kinetic effects. Lastly, we describe the measured potential for compositional homeostasis in our simulated mixed micelles, the basis for micellar self-reproduction, with implications for the study of the origin of life.
Construing the communication between powerhouse and ribosomal factory of cell: A small molecular viscometer comes to the rescue
Authors: Dutta Tanoy , Das Sreeparna , Gupta Ishaan , Koner Apurba
Published: February 2022

Fluorescent probes for specific inter-organelle communication are of massive significance as such communication is essential for a diverse range of cellular events. Here, we present the microviscosity-sensitive fluorescence marker, Quinaldine red (QR), and its dual organelle targeting light-up response in live cells. This biocompatible probe was able to localize in mitochondria and nucleolus simultaneously. While QR was able to sense the viscosity change inside these compartments under the induced effect of an ionophore and ROS-rich microenvironment, the probe’s ability to stain mitochondria remained unperturbed even after protonophore-induced depolarization. Consequently, a systematic quantification was performed to understand the alteration of microviscosity. Similar behavior in two distinct organelles implied that QR binds to Metaxin-2 protein, common to mitochondrial and nucleolar proteomes. We believe this is the first of its kind investigation that identifies the inter-organelle communications marker and opens up a new dimension in this field.
Layer-by-Layer Deposition of 2D CdSe/CdS Nanoplatelets and Polymers for Photoluminescent Composite Materials
Authors: Li Fuzhao , Klepzig Lars F. , Keppler Nils , Behrens Peter , Bigall Nadja C. , Menzel Henning , Lauth Jannika
Published: February 2022

Two-dimensional (2D) semiconductor nanoplatelets (NPLs) are strongly photoluminescent materials with interesting properties for optoelectronics. Especially their narrow photoluminescence paired with a high quantum yield are promising for light emission applications with high color purity. However, retaining these features in solid-state thin films together with an efficient encapsulation of the NPLs is a challenge, especially when trying to achieve high quality films with defined optical density and low surface roughness. Here we show photoluminescent polymer-encapsulated inorganic-organic nanocomposite coatings of 2D CdSe/CdS NPLs in poly(diallyldimethylammonium chloride) (PDDA) and poly(ethylenimine) (PEI), which are prepared by sequential layer-by-layer (LbL) deposition. The electrostatic interaction between the positively charged polyelectrolytes and aqueous phase transferred NPLs with negatively charged surface ligands is used as driving force to achieve self-assembled nanocomposite coatings with well-controlled layer thickness and surface roughness. Increasing the repulsive forces between the NPLs by increasing the pH value of the dispersion leads to the formation of nanocomposites with all NPLs arranging flat on the substrate, while the surface roughness of the 165 nm (50 bilayers) thick coating decreases to Ra = 14 nm. The photoluminescence properties of the nanocomposites are determined by the atomic layer thickness of the NPLs and the 11-mercaptoundecanoic acid ligand used for their phase transfer. Both, the FWHM (20.5 nm) as well as the position (548 nm) of the nanocomposite photoluminescence are retained in comparison to the colloidal CdSe/CdS NPLs in aqueous dispersion, while the measured photoluminescence quantum yield of 5 % is competitive to state-of-the-art nanomaterial coatings. Our approach yields stable polymer-encapsulated CdSe/CdS NPLs in smooth coatings with controllable film thickness, rendering the LbL deposition technique a powerful tool for the fabrication of solid-state photoluminescent nanocomposites.
ABOUT ILLEGAL INACTION OF PUBLIC LEGAL FORMATION IN THE SPHERE OF THINGS AND OTHER RELATED LEGAL RELATIONS
Authors: Барткова Ольга Георгиевна
Published: February 2022

Исследуется неправомерное бездействие как одна из форм поведения публично-правового образования, которое может повлечь за собой правовые последствия различной отраслевой принадлежности, включая и гражданско-правовые. Автор акцентирует внимание на последствиях негативного характера такого поведения, прежде всего, в сфере вещных отношений. Указаны наиболее типичные вредоносные последствия. Обосновывается, что такие последствия могут складываться как в сфере имущественных прав иных участников гражданского оборота (частных лиц), так и конкретного публично-правового образования. Неправомерное бездействие рассматривается как результат неосуществления (неисполнения) публично-правовым образованием (его соответствующими органами) государственных и муниципальных функций. Негативное значение бездействия публично-правового образования в сфере вещных отношений влияет также на механизм реализации субъективных гражданских прав, создавая препятствия в их осуществлении и, как правило, ведет к причинению вреда, что подтверждается примерами из судебной практики.

The article examines unlawful inaction as one of the forms of behavior of public law formation, which can entail legal consequences of various industries, including civil law. The author focuses on the consequences of the negative nature of such behavior, primarily in the sphere of material relations. The most typical harmful consequences are indicated. It is substantiated that such consequences can develop both in the sphere of property rights of other participants in civil turnover (individuals), and in a specific public law entity. Unlawful inaction is considered as a result of non-fulfillment (non-fulfillment) by a public-law entity (its respective bodies) of state and municipal functions. The negative significance of the inaction of public law formation in the sphere of real relations also affects the mechanism for the implementation of subjective civil rights, creating obstacles in their implementation and, as a rule, leads to harm, which is confirmed by examples from judicial practice.

Представлена проблема «правового вакуума» в регулировании предоставления услуг по обслуживанию общего имущества коттеджных поселков, вместе с тем, коттеджные поселки стали являться одной из привлекательных форм решения жилищных проблем граждан. Урегулирование общественных отношений в данной сфере по аналогии закона или аналогии права не всегда удается в силу правовой неопределенности. Необходимо внесение в законодательство Российской Федерации понятия о коттеджных поселках, а в жилищное законодательство - положений об управлении коттеджными поселками, а также норму о возникновении и прекращении права на долю в общем имуществе коттеджного поселка.

THE NUMERICAL STUDY OF DYNAMIC SUSCEPTIBILITY OF THE LAYERED FERROELECTRIC STRUCTURE
Authors:   Diponegoro University,Semarang, Indonesia, Gunawan Vincensius
Published: February 2022

In this study, we focused on the structure where a ferroelectric material (FE b) is sandwiched by the other type of ferroelectric material (FE a). The susceptibility is an important parameter which is determining the response of the materials to the external fields. In the numerical study, the susceptibility of the layered structure is obtained by applying the effective medium approach. The layered structure which is consisted of two or more different materials can be treated as one unit material which possesses effective susceptibility. This effective susceptibility is required when we study the optical behaviour of the layered structure. Here, we used entire-cell effective medium approximation. In this approximation, each layer of the ferroelectrics is considered to be comprised of several lattices. Then, by considering Maxwell continuity of fields across the lattices, the Landau-Khalatnikov (LK) equations of motion for each lattice are solved simultaneously to get the effective susceptibility of the layered system. In the calculation, we use parameters for FE which illustrates BaTiO3 while parameters for FE b are randomly vary. We found that the number of lattices in each layer affect the value of the effective susceptibility. We also found that an effective medium with two close resonance frequencies can be obtained when the difference of two resonance frequencies of the composed materials is around one percent of the higher frequency.

Published: February 2022

This article is based on research results that state that floods and droughts occur almost every year in many places in the biosphere. It happens because there is no proper water management. Rainwater is the primary water source in life; the balance between discharge and income (recharge) is not controlled. In this article, we try to manage rainwater by inviting the whole community with yard media, where every person in the world takes refuge in the yard. Data is taken from yards in the settlement of Surabaya, as a large city on the coast located in the lowlands, densely populated (100 inhabitants / Ha), prone to flooding and intrusion of seawater. They determined the size of the yard most inhabited by most people of Surabaya, namely the size of the land < 300m2, studied 40 yards as samples. The variables studied were: the land area of the yard, the site of the building, the canopy area of the trees, the size of ornamental plant headers, the scope of grass, the location of the open section, and the percentage of coarse grains (these six variables as predictors), rainfall (determined by intensity as a standard count), and runoff of water that comes out of the yard (as criterium). Results of analysis with multiple regressions; Successive yard variables are the area of the building, the location of grass, the site of open land, the scope of the tree canopy, gauze grains above the ground, and lastly, the area of ornamental plants. The six variables contributed to the surface runoff of 61.1%; thus, planning yard patterns in the city of Surabaya or other cities should pay attention to the role of these variables.

The process of deriving written descriptions from a picture based on the items and behaviours portrayed is known as image caption generation. The resulting description will represent what is in the image and the interactions among the objects. However, like with any other image processing challenge, recreating this characteristic in an artificial system is a difficult feat, and so the adoption Deep Learning procedures can help to tackle the problem. The main goal of this project is to generate an image captioning model that can provide a concise and relatable description of the picture by incorporating an attention mechanism. Ideally, the model can be separated into two components – one is called Encoder and the other is a Decoder. The encoder used here is a Google InceptionV3 pre-trained model. And the decoder is a language-based model, Gated Recurrent Unit (GRU) to translate the characteristics and objects provided by the encoder into natural sentences. Furthermore, the model's effectiveness is aided by the attention mechanism. To conclude, the model is trained on a subset of the MS COCO dataset, which contains about 80,000 pictures with at least five descriptions each and evaluated based on the BLEU score. To reduce the loss, the model weights are tuned using the categorical cross-entropy loss function. The results of the model are promising and competitive.

The geotechnical properties lateritic soil sample was upgraded with pulverized porcelaintiles (PPT). Lateritic soil sample was obtained and its index, specific gravity and compaction property was determined along with its California Bearing Ratio (CBR). Soil sample was obtained from Shagamu Interchange, Off Lagos-Ibadan expressway, South-West Nigeria while the pulverized porcelain tiles used were obtained from a construction site as waste. The soil samples were mixed with pulverized porcelain tiles in percentage by weight from 0 to 30% at an additional rate of 5%. The index properties of the natural soil showed the soil is silty clayey that belongs to group A-7-6 which is a poor soil according to AASHTO soil classification system. The soil naturally has a specific gravity of 2.65 with 37% of it particles passing 0.075mm, its LL, PL and PI are 46, 16, and 30% respectively, this depicts that the soil was a silty clayey high plastic soil (CH). The lateritic soil was altered by its compaction characteristics upon the addition of PPT which increased the liquid limit but gradually reduces the maximum dry density of the soil. The analyses of test results, it was found that Liquid Limit, Plastic Limit, Plasticity Index, and Optimum Moisture Content decreased consistently with the incremental addition of PPT up to 30%, whereas the Maximum Dry Density decreases with an increase in the optimum moisture content while the California Bearing Ratio (Soaked and Un-soaked) increased with PPT additive. Liquid Limit decreased from 46.7% (unmixed laterite) to 44.6% (30% PPT addition). The Plastic Limit decreased from 16% (natural state of laterite) to 15.6% (when mixed with 30% PPT) leaving the plasticity index reduced to 29% from 30.7%. The percentage of un-soaked CBR increased from 28% at 5% of PPT to 37.1%, while that of soaked CBR increased from 23% (unmixed soil) to 32.6% at 30% of PPT. Also, the free swelling potential of the clayey soil decreases as the percentage of PPT increases. The study asserts that 30% of PPT should be used to improve the geotechnical properties of a lateritic soil for highway construction.

Published: February 2022

The motive behind the selection of this topic is the wide range of application and usage of threads in today’s technology. It’s become essential to cut back the time for execution of various processes. So, developing solutions to problems using threads helps us solve multiple tasks in a very time economical manner. To accomplish this, a deep understanding of the concept of multi-threading is crucial. Our motive is to get thorough knowledge concerning this concept to enable us to use this concept ourselves towards a real-life problem. We will be using this concept to solve the subsequent problem: A man needs to cross a river. He possesses a tiger, a goat and a basket containing grass. There is a ship on the river. The utmost capacity of the boat is to hold two entities at a time. The man has to cross the river with his tiger, goat and basket of grass. If he goes with the basket at the opposite side of the river the tiger can eat the goat, if he takes the tiger with him to the opposite side then the goat can eat the grass from the basket. Here processes require resources which can be made available once the other process gets completed, these condition results in deadlock. The problem is how to design a discipline of behaviour (a concurrent algorithm) to seek out the sequence of the four will cross the stream safely.
SEMANTIC ANALYSIS OF LONG ANSWERS
Authors:   Rajiv Gandhi College of Engineering and Research, RGCER, Hingna, Nagpur, MH, India, Awale Deepratna
Published: February 2022

The inspiration for this research paper was the natural bias in university paper checking. When a paper is checked it is either checked by a professor who teaches the subject or someone who has no knowledge of the subject. When checked by the latter type, the answers cannot be appropriately marked unless obviously highlighted. This paper aims to check long answers without human intervention using artificial intelligence and regular expressions. It checks student or examinee written digital form answer by comparing it to an answer key which is to be provided by the exam host. The proposed methodology allows doing so by combining two techniques to get a faster and more accurate system to check long answers. The long answers will be evaluated by breaking them to simplest form of sentences and then encoding them to high density vectors using a Deep Averaging Network (DAN) to analyses the semantic similarity of the examinees answer to the provided answer key. This system does not look for only keywords in the content of the answer but looks at the sentence as a whole and if it evaluates similarly to the content in the answer key. This research relies on the availability of an answer key to check answers and does not check the relevance of content written by the examinee, meaning as long as examinee writes points mentioned in the answer key, he/she will be marked correct. This system of evaluation doesn't cut marks for wrong point (meaning no negative marking).

Study of the structure and properties of protective coatings obtained by the method of electric spark alloying with SHS electrodes (review)
Authors: Alymov M. I. , Stolin A. M. , Bazhin P. M.
Published: February 2022

Electric spark alloying (ESA) is a traditional method of obtaining protective coatings on the working surfaces of parts and mechanisms. A review of the results of studying the structure and properties of protective coatings obtained by the ESA method using SHS-electrodes is presented. Ceramic and cermet electrodes are obtained by the method of SHS-extrusion carried out under conditions of combustion processes with high-temperature shear deformation. SHS extrusion makes it possible to obtain electrodes with desired structure and properties in tens of seconds in one technological stage. The results on the study and application of electrode materials made of hard alloy materials, intermetallic compounds, materials based on the MAX-phase and ceramic materials with a nanoscale structure are presented. Analysis of the microstructure and properties of the formed alloy layers showed that the protective coating consists of at least two zones. The sizes of the structural wear-resistant components on the coating surface, usually correspond to their sizes in the original electrodes. When going in depth to the substrate, the grain size decreases and amounts to 20 – 100 nm. It is shown that a protective coating is formed on the surface which increases the mechanical and tribological properties. The presented results can be used in comparative tribological tests of hardened coatings, industrial tests of machined parts, etc.
Method for biochemical monitoring of iodine. Determination of iodide-ion in urine with an ion-selective electrode
Authors: Bebeshko G. I. , Dittrich M. B.
Published: February 2022

Determination of iodine in urine is an important methodology in the assessment of thyroid disorders. This indicator is often used in epidemiological studies of the state of iodine nutrition of the population, since the widespread prevalence of human iodine deficiency diseases is directly related to the lack of iodine intake with food and water. A method for the iodide ion determination in urine has been developed based on preliminary preservation of the sample in the presence of a buffer solution containing 4.28 %wt. H2O2 at pH 6.8 – 7.5 and measurements of the potential of the iodide selective electrode directly in the preserved sample solution without separation of the interfering components. After mixing the sample with a buffer solution in a ratio of 1:1, it is preserved after 18 – 24 h and stored for at least 30 days. The interfering effect of macro- and micro-components has been studied. It is shown that the amount of sodium chloride in the sample should be taken into account only in studying the severe iodine deficiency (≤20 μg/liter) and urea does not affect the potential of the electrode. To assess the total effect of the organic components of urine, we compared the results of parallel determinations of iodine in the samples, one of which was preserved, and organics was removed from the second one by alkaline ashing. It is shown that the discrepancies in the results were random and did not exceed 11.3 %. Iodine loss has not been determined, the bias between the concentration of the introduced and found additives was insignificant. Thus, in a buffer solution with hydrogen peroxide, not only the preservation of the urine sample for a long time takes place, but also the interfering influence of inorganic and organic components of the sample matrix on the membrane of the ion-selective electrode is eliminated. Metrological evaluation of the developed methodology was performed, which showed the precision and trueness of the procedure. The method was tested in an experiment on the correction and enrichment of iodine in the diet of schoolchildren. The low cost, convenient and easy to use equipment, the possibility of long-term storage of preserved samples makes the method mobile and suitable for biochemical monitoring of iodine consumption and deficiency during a large-scale population survey.

Plastic deformation is a type of material damage which can disrupt the normal operation of the structure. In this regard, the method for assessing the degree of damage to a metal sample has been developed. A corset sample for tensile tests was made from an aluminum alloy of the Al – Zn – Mg – Cu system. The ANSYS finite element complex was used to simulate an inhomogeneous stress state occurred in the sample working zone due to the variable cross-section upon tension. First, the hardness of the corset sample was measured, then it was tested for tension until the onset of necking and the load drop on the deformation diagram. After unloading along the sample working area, the Brinell hardness and surface roughness were measured. The results of the hardness measurements showed that in the areas where the tensile stresses are below the conditional yield stress of the material, the hardness value corresponds to the hardness of the starting material. In the areas where the tensile stresses are higher than the conventional yield stress, the hardness increases and reaches the maximum value in the center of the specimen, i.e., in the zone of the minimum cross-section. Thus, the damageability of the material can be assessed through the change in the hardness and roughness of the surface along the sample length. Proceeding from the results of instrumental spherical indentation, a technique for assessing the mechanical characteristics of the material was developed. The method consists in testing one sample for hardness and tensile strength with subsequent construction of the correlation dependences of tensile and indentation loads using the experimental results to obtain calculated tensile diagrams from the indentation diagrams of the material under study.

Background: Hypoglycaemia is a common and potentially life-threatening condition in people with diabetes, commonly caused by medications such as insulin. Hypoglycaemic events often require in-patient treatment and/or follow-up with a diabetes specialist nurse (DSN) or GP to make
adjustments to medication. This referral pathway commonly relies on patient self-referral to primary care, and as a result many patients are not actively followed up and go on to experience repeat hypoglycaemic events.Methods: Randomised controlled trial in partnership with East
Midlands Ambulance Service NHS Trust. People with diabetes calling out an ambulance for a severe hypoglycaemic episode and meeting the eligibility criteria were randomised to either a novel DSN-led pathway or to their general practice for routine follow-up. Primary outcome was proportion of
participants with a documented consultation with a healthcare professional to discuss the management of their diabetes within 28 days of call-out.Results: 162 people were randomised to one of the pathways (73 DSN arm, 89 GP arm) with 81 (50%, 35 DSN, 46 GP) providing full consent
to be followed up. Due to lower than anticipated randomisation and consent rates, the recruitment target was not met. In the 81 participants who provided full consent, there were higher rates of consultation following the call-out when referred to a DSN compared to primary care (90% vs. 65%).
Of the 81 participants, 26 (32%) had a second call-out within 12 months.Conclusions: Consultation rates following the call-out were high in the DSN-led arm, but there was insufficient power to complete the planned comparative analysis. The study highlighted the difficulty in recruitment
and delivery of research in pre-hospital emergency care. Further work is needed to provide more feasible study designs and consent procedures balancing demands on ambulance staff time with the need for robust well-designed evaluation of referral pathways.

Yirminci yüzyılda yönetim bilimleri içerisinde tartışılmaya başlanan kurumsal sosyal sorumluluk (KSS) kavramı, özellikle son otuz yıl içerisinde çok fazla üzerinde durulan bir konu haline gelmiştir. Süreç içinde bu kavramın, finans bilimcilerinin de ilgisini çekmesi sonucu işletmelerin finansal performansı üzerine etkisini araştıran birçok görgül ve kuramsal araştırmalar yapılmış ve farklı sonuçlara ulaşılarak genel bir yargı elde edilememiştir.

Çalışmanın amacı, BİST100 endeksinde yer alan bankaların finansal göstergelerine bakarak kurumsal sosyal sorumluluk düzeyleri ile finansal performansları arasındaki ilişkiyi istatistiksel olarak analiz etmek, bir ilişki söz konusu ise bu ilişkinin derecesini tespit etmektir. BIST 100 endeksinde yer alan 8 adet banka üzerinde, 2009-2018 (10 dönem) yılları arasında inceleme yapılmıştır.

Bu çalışmada, katılım bankalarında gerçekleştirilen fon kullandırım işlemleri ile ilişkili müşterilerden tahsil etmiş oldukları ücret ve komisyonların aslında kardan bağımsız şekilde tahsil edilerek gelir kaydedilmemesi, söz konusu rakamın, müşteri adına banka tarafından ödenen masraflar karşılığı kadar olabileceği, masraf karşılığını aşan bir ücret alınacak ise de bu rakamın kar rakamına dahil edilmesi gerektiği yönünde oluşan görüşü detaylandırarak, sayısal örnek ile konuyu daha anlaşılır hale getirmek amaçlanmıştır.

Exposure to inspirational and relatable role models is crucial towards fostering engagement of learners with scientific disciplines. However, the representation of scientists in popular culture is still far from being adequately gender- and race-inclusive. This study evaluated the gender balance and impact of scientific role models using a two-pronged experimental approach. The gender balance was investigated in search engines, online databases, and school curricula. A survey was used to investigate English secondary students’ awareness of role models and intentions to pursue further scientific studies. Our findings revealed a widespread female underrepresentation amongst scientific role models in all the analysed online sources and in high school curricula provided by the three main English exam boards. The survey (n = 356) revealed that students were considerably more likely to identify famous male than female scientists. While awareness of female role models was significantly associated with students’ gender, this was not the case for male role models. A statistically significant correlation was also observed between the number of identified role models and intentions to pursue scientific studies in Key Stage 4 girls. This study reinforces the urgency of ensuring school curricula and online resources provide a more modern and inclusive representation of scientists.

Today, cancer had been described as one of the deadliest diseases worldwide. It has been estimated that cancer causes about 9.9 million deaths in the year 2020. The conventional treatment for the disease involves single chemotherapy or a combination of mono-chemotherapy and or a combination of mono-chemotherapy and radiotherapy. However, there are negative sides to these approaches which have prompted the search for new therapeutic drugs. In view of this, scientific communities have started looking for innovative sources of anticancer compound of natural origin which include traditional plants. Nowadays, several studies have evaluated the anticancer properties of bioactive components (phytochemicals) derived from the plants both in vivo and in vitro. The phytochemicals are secondary metabolites or chemical compound produced during metabolic process in plants which are useful in the protection of plants. Most of these phytochemicals such as alkaloid, flavonoids, phenolic compounds, cyanidin, fisetin, genistein, gingerol kaempferol, quercetin, resveratrol possessed certain medicinal properties and found to have numerous applications in pharmaceutical industries for treatment of cancer. The paper was aimed to review some plants bioactive components (phytochemicals) used in cancer treatment.

In section Dentati, the chromosome numbers were reported from only eight of 30 taxa. There is no chromosomal record relating to the other 22 taxa. In the present study, it is intended to detect the chromosome numbers of section Dentati taxa. Chromosome numbers of 15 taxa were obtained, 13 of which were reported for the first time and two numbers agreed with the previous reports. 14 taxa were diploid with 2x = 30 and only one taxon was polyploid with 4x = 60. Polyploidy might have played a role in the karyotype evolution of the genus. Although polyploidy was seen, there was no dysploidy causing to change in the basic chromosome number. According to all chromosomal data on Dianthus, the basic chromosome number was only one (x = 15). In conclusion, this study presents new data into the karyological characteristics of section Dentati (genus Dianthus) that may be useful for understanding or interpreting relationships among the sections.

Hypertension is a state of increasing systolic blood pressure of more than 140 mmHg and diastolic blood pressure of more than 90mmHg on 2 measurements with an interval of 5 minutes in a fairly calm state. Pharmacological management of hypertension refers to the Guideline Joint National Committee (JNC) 8 of 2014. The use of pharmacological therapy can cause problems, one of which is drug interactions. The complexity of using drugs tends to increase drug interactions. In this study, a potential drug interaction study was conducted to determine the magnitude of the potential interactions that might occur between drugs. The method used is descriptive method. The population in this study were medical records of hypertensive drug users diagnosed. Data analysis used univariate data analysis and the use of the Lexicom application. The results of the characteristics of hypertension drug users were 57,69% women and 42,31% men. Characteristics based on age were the youngest age 40 years (0.77%), 74 years old (0.77%) and the average age 61 (9.23%) years. The class of drugs used was 53.71% Calcium Channel Blocker, 28% Angiotensin Receptor Blocker, 8.57% Angiotensin Converting Enzyme, 8% Beta Blocker and 1.71% Diuretic. The severity of hypertension medication was moderate 63.11%, Major 3.88%, minor 33.01%. Based on the results obtained, the majority of women using hypertension drug characteristics were 58% and the average age was 61 (8.9%) years. The majority of the drugs used were 54% Calcium Channel Blockers with a moderate majority of 64%.
