Published: November 2018

Penelitian studi tentang Metamaterials (MTMs) dalam beberapa tahun terakhir telah meningkat sangat pesat. Metamaterials yang di sebut juga artificial material atau Left Handed (LH) material adalah material yang tidak ada dialam dimana strukturnya direkayasa oleh manusia yang memiliki dua atau lebih properties yang khusus, misalkan pada Double Negative (DNG) material yang memiliki μ negative dan ε negative. Beberapa pendekatan dalam mendesign metamaterial yaitu pendekatan resonant dan pendekatan Transmission line. Model transmision line yang pertama adalah Right Handed Transmission lines (RH TL) yang dimodelkan dalam sebuah unit sel sebagai rangkaian dan shunt kapasitor shunt(CR), yang kedua adalah Left Handed Transmission Line (LH TL) dimodelkan dalam sebuah unit sel sebagai rangkaian kapasitor seri(CL) dan induktansi shunt(LL). gabungan dari dua buah model transmission line ini disebut Composite Right-left Handed Transmission Line(CRLH TL) dan ini menjadi dasar dalam mendesign metamaterial. CRLH transmission line dimodelkan dalam sebuah unit sel sebagai rangkaian kapasitor seri(CL), induktansi seri(LR) dan induktansi shunt (LL) serta induktansi shunt(LL). CRLH TL memiliki negatif, nol dankonstanta propagasi positif sesuai dengan karakteristik dari permitivitas efektif dan permeabilitas[1]. Hasil pengukuran bandpass filter menggunakan saluran transmisi CRLH satu sel menunjukkan frekuensi cutoff pada -10dB terletak pada frekuensi 3.016 GHz pada highpass filter dan 5.359GHz pada lowpass filternya. Sedangkan frekuensi 3.4 GHz terletak pada -4.8415 dB sedangkan frekuensi 4.8 Ghz terletak pada -4.753 dB. Hasil dari perancangan menunjukkan bahwa saluran transmisi CRLH satu sel dapat memenuhi spesifikasi yang diminta.

Published: November 2018

Ground Penetrating Radar (GPR) adalah salah satu jenis radar yang digunakan untuk menyelidiki kondisi di bawah permukaan tanah tanpa harus menggali dan merusak tanah. Sistem GPR terdiri atas pengirim (transmitter), yaitu antena yang terhubung ke generator sinyal dan bagian penerima (receiver), yaitu antena yang terhubung ke LNA dan ADC yang kemudian terhubung ke unit pengolahan data hasil survey serta display sebagai tampilan output-nya dan post processing untuk alat bantu mendapatkan informasi mengenai suatu objek. GPR bekerja dengan cara memancarkan gelombang elektromagnetik ke dalam tanah dan menerima sinyal yang dipantulkan oleh objek-objek di bawah permukaan tanah. Sinyal yang diterima kemudian diolah pada bagian signal processing dengan tujuan untuk menghasilkan gambaran kondisi di bawah permukaan tanah yang dapat dengan mudah dibaca dan diinterpretasikan oleh user. Signal processing sendiri terdiri dari beberapa tahap yaitu A-Scan yang meliputi perbaikan sinyal dan pendektesian objek satu dimensi, B-Scan untuk pemrosesan data dua dimensi dan C-Scan untuk pemrosesan data tiga dimensi. Metode yang digunakan pada pemrosesan B-Scan salah satunya adalah dengan teknik pemrosesan citra. Dengan pemrosesan citra, data survey B-scan diolah untuk didapatkan informasi mengenai objek. Pada penelitian ini, diterapkan teori gradien garis pada pemrosesan citra B-scan untuk menentukan bentuk dua dimensi dari objek bawah tanah yaitu persegi, segitiga atau lingkaran.

Aim. To establish associations of the frequency of detection of clusters and components of the metabolic syndrome (MS) with the prevalence of depression in open male population of moderately urbanized Siberian city.Material and methods. Cross-sectional epidemiological survey included 1000 individuals formed from the election list of males in one of the Tyumen administrative districts. The response rate was 85,0%. MS was assessed using the International Diabetes Federation (IDF) criteria. A self-administered WHO MONICA-psychosocial questionnaire was used to assess the levels of depression. Statistical analysis was conducted using a package of software program for medical data IBM SPSS Statistics 21.0.Results. In the open population of moderately urbanized Siberian city in men (age 25-64) with depression the following clusters of MS are prevalent: abdominal obesity (AO) + hypertriglyceridemia (HTG) + decrease of high-density lipoprotein cholesterol (hypoHDL-C) and AO + hypoHDL-C + arterial hypertension (AH); in the presence of a high level of depression AO + HTG + hypoHDL-C and AO + hypoHDL-C + AH are prevalent. A direct correlation was established between the prevalence of depression and abdominal obesity and hypertension, as well as the prevalence of a high level of depression with HTG and hypo-HDL cholesterol. In the open urban population in men (age 25-64) with high level of depression the following clusters of MS are prevalent: AO + HTG + hypoHDL-C and AO + HTG + hypoHDL-C + AH. We established an increase in the chances of developing a high level of depression with following MS clusters: AO + HTG + hypoHDL-C. According to IDF criteria, the prevalence of MS components in male population (age 25-64) in Tyumen was: AO — 42,6%; AH — 59,8%; hyperglycemia — 17,4%; HTG — 10,5%; hypoHDL-C — 4,6%. With a primary prevalence of MS components in men (age 25-64) with a low level of depression, the prevalence of HTG and hypoHDL-C in open population of moderately urbanized Siberian city prevails in men with high and mean levels of depression.Conclusion. The strategies for MS prevention in men of moderately urbanized city should contain measures to optimize nutrition regarding psychosocial determinants. This is due not only to the wide prevalence of overweight and obesity in Tyumen population but also to dyslipidemia associated with these factors.
Tobacco Use Assessment and Treatment in Cancer Patients: A Scoping Review of Oncology Care Clinician Adherence to Clinical Practice Guidelines in the U.S.
Authors: Price Sarah N. , Studts Jamie L. , Hamann Heidi A. 
Published: November 2018

AbstractBackgroundSmoking after a cancer diagnosis negatively impacts health outcomes; smoking cessation improves symptoms, side effects, and overall prognosis. The Public Health Service and major oncology organizations have established guidelines for tobacco use treatment among cancer patients, including clinician assessment of tobacco use at each visit. Oncology care clinicians (OCCs) play important roles in this process (noted as the 5As: Asking about tobacco use, Advising users to quit, Assessing willingness to quit, Assisting in quit attempts, and Arranging follow-up contact). However, OCCs may not be using the “teachable moments” related to cancer diagnosis, treatment, and survivorship to provide cessation interventions.Materials and MethodsIn this scoping literature review of articles from 2006 to 2017, we discuss (1) frequency and quality of OCCs' tobacco use assessments with cancer patients and survivors; (2) barriers to providing tobacco treatment for cancer patients; and (3) the efficacy and future of provider-level interventions to facilitate adherence to tobacco treatment guidelines.ResultsOCCs are not adequately addressing smoking cessation with their patients. The reviewed studies indicate that although &gt;75% assess tobacco use during an intake visit and &gt;60% typically advise patients to quit, a substantially lower percentage recommend or arrange smoking cessation treatment or follow-up after a quit attempt. Less than 30% of OCCs report adequate training in cessation interventions.ConclusionIntervention trials focused on provider- and system-level change are needed to promote integration of evidence-based tobacco treatment into the oncology setting. Attention should be given to the barriers faced by OCCs when targeting interventions for the oncologic context.Implications for PracticeThis article reviews the existing literature on the gap between best and current practices for tobacco use assessment and treatment in the oncologic context. It also identifies clinician- and system-level barriers that should be addressed in order to lessen this gap and provides suggestions that could be applied across different oncology practice settings to connect patients with tobacco use treatments that may improve overall survival and quality of life.

Abstract

Background
Rapid advances in science challenge the timely adoption of evidence-based care in community settings. To bridge the gap between what is possible and what is practiced, we researched approaches to developing an artificial intelligence (AI) application that can provide real-time patient-specific decision support.

Materials and Methods
The Oncology Expert Advisor (OEA) was designed to simulate peer-to-peer consultation with three core functions: patient history summarization, treatment options recommendation, and management advisory. Machine-learning algorithms were trained to construct a dynamic summary of patients cancer history and to suggest approved therapy or investigative trial options. All patient data used were retrospectively accrued. Ground truth was established for approximately 1,000 unique patients. The full Medline database of more than 23 million published abstracts was used as the literature corpus.

Results
OEA's accuracies of searching disparate sources within electronic medical records to extract complex clinical concepts from unstructured text documents varied, with F1 scores of 90%–96% for non-time-dependent concepts (e.g., diagnosis) and F1 scores of 63%–65% for time-dependent concepts (e.g., therapy history timeline). Based on constructed patient profiles, OEA suggests approved therapy options linked to supporting evidence (99.9% recall; 88% precision), and screens for eligible clinical trials on ClinicalTrials.gov (97.9% recall; 96.9% precision).

Conclusion
Our results demonstrated technical feasibility of an AI-powered application to construct longitudinal patient profiles in context and to suggest evidence-based treatment and trial options. Our experience highlighted the necessity of collaboration across clinical and AI domains, and the requirement of clinical expertise throughout the process, from design to training to testing.

Published: November 2018

The long history of development of deposits of lead-zinc ores of the Sadonsky mining region led to the formation of extensive halos of chemical pollution of surface watercourses. Aim. The aim of this study is to monitor surface watercourses in the area of the Unalsky tailing dumps and the Kholst deposit by points of sampling of 1992-2004. Sampling was conducted in the summer of 2016. Methods. The content of heavy metals of 2 and 3 hazard classes (Pb, Cd, Ni, Zn and Cu) was studied by atomic absorption. The contribution of the Unaldon River and Unalsky tailing dump to the pollution of the Ardon River. Results. The highest content of cadmium, lead and zinc, significantly exceeding the maximum permissible concentrations (MPC) in the water bodies of cultural and domestic use is found in the Ardon River down from the Unalsky tailing dump. The flow of heavy metals into the Unaldon River with adit waters compared with the observation period of 1992-2004 decreased noticeably. In conditions of a reduction in the production capacity of mining and processing enterprises, the leaching of heavy metals from mountain dumps and excavations make an insignificant contribution to the pollution of the Ardon River in comparison with the Unalsky tailing dump. Conclusion. The state of the Ardon River down from the discharge from the tailing dump corresponds to the "environmental disaster" category. The condition of the rivers Mayramdon and Unaldon according to the content of heavy metals corresponds to a "relatively satisfactory" type.

Aim. The aim is to study the modern and ancient basin of the Ural River and establish the cause of its shallowing, as well as the disappearance of small rivers and tributaries of the Ural River. Methods. The research method consists in the generalization and reduction to a single scale of all cartographic and space-survey documents, as well as the identification of elements of hydrography and relief created by ancient watercourses. Results. At present, many countries experience a shortage of fresh water. A person uses a huge amount of fresh water to meet his daily needs. In addition, contaminated waste technical waters are discharged into rivers and lakes. The Republic of Kazakhstan occupies most of the Caspian lowland, with the only full-flowing river, Ural (the Kazakh name is Zhayik). However, this river is becoming shallow, its level and spring floods are becoming lower. Cut-off lakes are also drying and disappearing. Small rivers that flew into the Ural river have almost disappeared and water level increases only during the melting of snow and after heavy rains. The studied territory is located in the arid climate zone, where there is little snow, and rains are rare. Conclusions. However, studying the cartographic and space imagery, we can say that there are many dry channels in the Caspian lowland. It must be assumed that this region was sufficiently moist, with a large number of rivers and lakes.

Published: November 2018

Aim. The aim is to study the ontogeny and structure of introduced populations of useful plants in Central Yakutia. Methods. Description of the ontogeny of the plants under study was carried out with the determination of ontogenetic states according to generally accepted methods. After planting, current measures were taken to care for plants with elimination of weeds and preservation of the undergrowth. The number of plants at the planting sites was calculated annually. Results. In plants, there is a polyvariety of the rate of development, in which the life cycle is shortened in individuals, the rate of development is accelerated or the ontogenetic states are missed, and there is also transition of plants to a temporarily non-flowering state. All studied introductory populations were left-sided and had different absolute maxima, which depended on the life form and duration of plant stay in culture. Conclusions. Among young monocentric plants we saw the development and attenuation of the population (Delphinium grandiflorum, Linum komarovii, Plantago major, Redowskia sophiifolia). In them, absolute maximums fall on juvenile, immitric, virginile and young generative groups. In populations of monocentric perennial plants, Lilium pensylvanicum and Adonis sibirica, absolute maxima fall on virginile groups. For studied years, the nature of the developmental spectrum in populations of Clausia aprica and Tussilago farfara has not changed with the absolute maximum in the virginal group.

Aim. The human factor has a significant influence on the development cycles of flora and fauna in the republic, including ticks, in which life cycles are associated with parasitization of agricultural animals, where biotopes are farm buildings, virgin and fallow pastures. Global changes in agriculture over the past two decades have led to an increase in natural pastures, reduction in the areas of sowing grasses, an increase in biotope areas and a number of parasitic ticks on animals. In this regard, we set a goal to study the ecological and biological features of the distribution of biotopes of arthropod parasites in the republic. Material and methods. The material of the study was ticks collected from cattle, sheep and horses in various zones. Collection of ticks was carried out by epizootic and regular methods. Observations, using the direct collection method, have been carried out for 7 years. Results. The researches revealed the presence of 4 genera of Ixodes ticks in the Republic: Hyalomma, Boophilus, Rhipicephalus and Dermacentor, and the genus Hyalomma occurs mainly in the Tersko-Sulak lowland, the rest can be discovered throughout the territory of Chechnya. Their species composition is represented by H. scupense, H. anatolicum, H. marginatum, H. plumbeum; B. annulatus; D. reticulatus, D. marginatus, D. daghestanicus and R. bursa. Conclusion. Through the infected eggs of the tick, further infection of the larvae takes place, which in turn, after molting, turn into the nymph and infect healthy animals, as well as the adult. The natural and climatic conditions of the Republic favor such a cycle of development of ticks.

Aim. The aim is to investigate the relationship between the content of micronuclei, destructive disorders in the nuclei of erythrocytes of peripheral blood of the goby fish and intensity of lipid peroxidation in fish tissues. Methods. Was used the method of quantitative accounting of morphologically altered red blood cells of peripheral blood of goby fish. Evaluation of cytogenetic disorders in fish blood cells was carried out based on a micronucleus test. Samples of muscle tissues and liver were sampled for biochemical analyzes. The rates of lipid peroxidation (LPO level) were determined by a method based on the reaction of malondialdehyde and thiobarbituric acid, the end product of lipid peroxidation. Results. A correlation was found between the rates of spontaneous LPO, ascorbate-dependant LPO and the accumulation of malondialdehyde in the liver of fish and changes in the nucleus of erythrocytes (R2 =0,8; R2 =0,6; R2 =0,7, respectively). Conclusions. We established the functional dependence which justifies the need to use cytogenetic markers to assess the impact of adverse environmental factors on the body of hydrobionts.

Published: November 2018

Corrosion is a severe matter regarding the most of metal using industries such as the crude oil refining. The formation of the oxides, sulfides or hydroxides on the surface of metal due to the chemical reaction between metals and surrounding is the corrosion that highly depended on the corrosive properties of crude oil as well as the chemical composition of ferrous metals since it was expected to investigate the effect of Murban and Das blend crude oils on the rate of corrosion of seven different ferrous metals which are used in the crude oil refining industry and investigate the change in hardness of metals. The sulfur content, acidity and salt content of each crude oil were determined. A series of similar pieces of seven different types of ferrous metals were immersed in each crude oil separately and their rates of corrosion were determined by using their relative weight loss after 15, 30 and 45 days. The corroded metal surfaces were observed under the microscope. The hardness of each metal piece was tested before the immersion in crude oil and after the corrosion with the aid of Vicker’s hardness tester. The metallic concentrations of each crude oil sample were tested using atomic absorption spectroscopy (AAS). The Das blend crude oil contained higher sulfur content and acidity than Murban crude oil. Carbon steel metal pieces showed the highest corrosion rates whereas the stainless-steel metal pieces showed the least corrosion rates in both crude oils since that found significant Fe and Cu concentrations from some of crude oil samples. The mild steel and the Monel showed relatively intermediate corrosion rates compared to the other types of ferrous metal pieces in both crude oils. There was a slight decrease in the initial hardness of all the ferrous metal pieces due to corrosion.
