Published: November 2019

Pengawasan tempat/ruangan dalam pekerjaan merupakan hal  penting, dimana dengan adanya CCTV pemantau kita bisa melihat kondisi suatu tempat dengan bantuan kamera pemantau (CCTV). Selama ini untuk perekaman CCTV mengunakan DVR (Digital Video Recording) dimana perangkat ini cenderung mahal dan belum menjangkau semua kalangan. Terlebih lagi jika CCTV merekam secara terus menerus 24 jam sehari selama 1 bulan, tentu harus menyediakan kapasitas ruang harddisk yang besar.

Ruang Lab FTIK menjadi objek penelitian dimana mengunakan perangkat raspberry pi dengan modul kamera dan sensor motion detection dimana perangkat PC Mini Raspberry  Pi hanya akan merekam kondisi ruangan hanya pada saat terdeteksi suatu gerakan pada ruang Lab FTIK. Raspberry pi sendiri adalah sebuah komputer mini, sistem operasi Raspberry bisa bermacam-macam, salah satunya adalah Linux Debian yang telah dipaket minikan. Dengan itu diharapkan mampu mengurangi beban media penyimpanan. Penggunaan Raspberry Pi dalam hal pengawasan/monitoring tempat atau ruangan  memerlukan biaya yang murah dan efektif dalam pendayagunaan.

Authors: Matolinets N.W. , Pidhirnyy Ya.M , Netliukh A.M.
Published: November 2019

Objective – to establish the value of non-invasive monitoring of central hemodynamics during the acute period of polytrauma and its impact on systemic respiratory and circulatory parameters and intensive care treatment using the estimated Continuous Cardiac Output (esCCO), a non-invasive continuous measurement technique of central hemodynamics, which was integrated into the Life Scope monitor (Nihon Kohden, Japan). module.Materials and methods. The study included 170 patients with polytrauma who were treated in our intensive care unit. Patients with severe polytrauma (ISS 20–30 points) were included in the group 1 (n = 70), with an average age of (41.9 ± 2.4) years. The group 2 (n = 100) consisted of patients with moderate polytrauma (ISS 10–19 points), the average age of the patients in this group was (38.7 ± 2.5) years. In sub-groups 1А and 2А adequate circulating blood volume measurement and subsequent support was performed using the esCCO. In subgroups 1B and 2B, the analysis of systemic hemodynamics such as ECG and blood saturation was performed using standard multifunction monitors.Results. Hemodynamic disorders in the form of arterial hypotension < 70 mm Hg on admission occurred in 14.3 % of patients in group 1, and was not observed in patients within the group 2. The normalization of systemic hemodynamics was observed after 24 hours of intensive care therapy, in particular in subgroup 1А a marked increase in the systemic blood pressure and subsequent termination of tachycardia was observed. Normalization of cardiac output and cardiac index in subgroup 1А was observed after 3–6 h of infusion therapy (IT), in the subgroup 2А – after 12 h IT. In the subgroup 1А the infusion volume during the first day differed significantly, 8.9 % less if compared to the infusion volume used in subgroup 1B. In moderate-severity polytrauma, the infusion volume was significantly smaller than in severe polytrauma, and in the subgroup 2А it was significantly lower by 8.6 %, compared to the infusion volume used in the subgroup 2B. The confirmation of the effectiveness of the balanced IT was the normalization of the urine output. Namely: on day 2 in the subgroup 1А the diuresis increased significantly compared to day 1, and in the subgroup 1B it did not change significantly. Intergroup differences in mean daily diuresis in the group 2 were significant after 12 h of IT.Conclusions. Carrying out monitor-controlled infusion and respiratory therapy with the usage of the esCCO monitoring technique allowed to achieve an early normalization of central and systemic hemodynamics during the intensive care of polytrauma patients with a significantly smaller volume of infusion, contributed to the elimination of hypoxia, and was accompanied by a significant reduction, namely by 21.1 %, in the duration of mechanical ventilation in severe polytrauma.

Objective – to explore the possibility of integral assessment of the stroke outcome and to develop a method of integral assessment of the stroke outcome after in-patient treatment on the level of impairment and and the level of activities of daily living, which were assessed using rating scales and indices.Materials and methods. The study was conducted at the Stroke Center (SC), Oberig’ multidisciplinary hospital division, which operates according to the principles of Comprehensive Stroke Unit. Patients with a cerebral stroke who were admitted to the SC in 2010–2018 were enrolled. The data of the participants were prospectively entered into a special database and included discharge assessments using 8 valid rating scales and indices. Cluster analysis methods (in particular Kohonen neural networks) were used to design the integral assessment. Statistical analysis of the values ​​of the rating scales and indices in the selected clusters was performed using the Kruskal–Wallis criterion, post hoc comparisons were made using the Dunn multiple comparison criterion.Results. 852 patients (42.5 % women and 57.5 % men, median age – 66.7 year) were enrolled. 81 % of patients were diagnosed with ischemic stroke, and 19 % had hemorrhagic stroke. According to the chosen method, it is necessary and sufficient to split the data into 4 clusters. All participants in the study according to their assessments at discharge using the set of selected measures could be assigned to one of 4 isolated clusters: K1 (n = 366), K2 (n = 93), K3 (n = 104) or K4 (n = 289). National Institutes of Health Stroke Scale, modified Rankin scale, Barthel Index, Berg Balance Scale та Functional Ambulation Classification were the most significant determinants of the patient cluster. For the 5 measures there have been significant differences (p < 0.001) in the four clusters. The condition of the patients in K4 cluster was the best (p < 0.05), whereas the patients in the K1 cluster were worse (p < 0.05), and the condition of the patients in the clusters K2 and K3 was much worse (p < 0.05) compared with the cluster K4.Conclusions. Based on the integrated assessments of neurological impairments and activities of daily living all of stroke patients could be assigned to one of four identified clusters. Detecting predictors of poor outcome after in-patient management may help to find ways to improve their prognosis.

Published: November 2019

Objective – to determine the effectiveness of endovascular treatment of fusiform arterial aneurysms of cerebral vessels.Materials and metods. The results of endovascular treatment of 25 patients with fusiform cerebral aneurysms who were treated at the Center in the period from 2011 to 2018 were analyzed. There were 12 men (48 %), women – 13 (52 %). The average age of patients is 48 years. In 17 (68 %) cases were vertebrobasilar aneurysms, in 2 (8 %) cases – aneurysms of the anterior cerebral artery, in 3 (12 %) cases – aneurysms of the middle cerebral artery, in 3 (12 %) cases – aneurysms of internal carotid arteries. For the treatment of patients we used various stents: flow diversion (FRED (Microvention, USA), Pipeline (ev3, USA)), Derivo (Acandis, Germany)) and protection stents (Leo (Balt, France), Solitaire (Medtronic, USA)), in deconstructive interventions – detachable coils.Results. It were performed 25 surgical interventions: in 23 (92 %) cases – reconstructive shutdown, in 2 (8 %) – deconstructive shutdown. There were no technical problems during surgical interventions. Complications were noted in two cases with VBB aneurysms in the early postoperative period stem disorders appeared due to the increasing mass effect. Both patients were dead. Control examination in a period from 6 months to 3 years 13 (52 %) patients were performed. The results of excluding aneurysms were evaluated on a Raymond–Roy scale. The type 1 was detected in 7 (53.8 %) patients, the type 2 – 1 (7.7 %), the type 3 – 5 (38.5 %). In 2 (15.4 %) patients bearing artery thrombosis was detected.Conclusions. Extrasacular endovascular methods of treating fusiform arterial aneurysms of cerebral vessels are effective and relatively safe. They can expand the indications for endovascular treatment of these aneurysms, however compared with the treatment of saccular aneurysms hemodynamic changes and secondary aneurysm thrombosis are unpredictable and require further study.

Authors: Polkovnikov O.Yu. , Materukhin A.M.
Published: November 2019

Objective – to evaluate the advantages of tri-axial systems with the possibility of «distal access» with endovascular embolization of cerebral aneurysms of the anterior circulation in the acute period of rupture.Materials and methods. In the course of consecutive 15 operations, endovascular embolization of cerebral aneurysms in the acute rupture period, a triaxial access system was used. The system included a «long» introducer (IVA LONG IVA 6F80, Balt), a distal access catheter (Fargo 6F 115 cm in 8 cases, FargoMax 6F 115 cm in 2 cases and Sofia 6F 115 cm in 1 case) or a guiding catheter (Chaperon 6F in 4 cases) and a microcatheter (Vasco+ 10D or Headway 17) with a microguidewire (Hybrid 1214, Traxcess 14, Avigo, Agility 14). To identify intraoperative complications, angiography data were analyzed and the diameter of the arteries before and after the intervention was measured. Evaluation of angiographic data was performed in standard, and if necessary, additional projections. The diameter of the vessels (A1-A2-segments of the Anterior Cerebral Artery (ACA), М1-М2-segments of the Medial Cerebral Artery (MCA), petrosium and cavernous segment of the Internal Cerebral Artery (ICA) was measured in the anterior–posterior plane. Immediately after the operation, all patients underwent control computed tomography. Results. In all cases, there were no pronounced difficulties in navigating and catheterizing the cavity of the aneurysm, there was no need to reconfigure the tip of the microcatheters or change the microguidewire. The microcatheter did not lose its «controllability» even against the background of the pronounced tortuosity of the brachiocephalic arteries or iliac segments. By the end of the operation, in no case was an increase in angiospasm noted. In all observations, a regression of the severity of spasm was noted, with the absence of the latter in 12 cases. In none of the cases were there intraoperative thromboembolic or hemorrhagic complications.Conclusions. Tri-axial access provides good proximal support and reduces the risk of developing intraoperative complications during endovascular embolization of aneurysms of the anterior circulation in the acute period of rupture. When accessing the aneurysms of the anterior cerebral anterior communicating artery complex, the routine use of distal access catheters is justified.

Published: November 2019

A clinical case with the choice of an individual strategy and tactics of endovascular treatment of a patient with fusiform aneurysm de novo of a branch of the middle cerebral artery is considered. Diagnosis and treatment was carried out in Scientific-practical Center of endovascular neuroradiology of the National Academy of Medical Sciences of Ukraine. Patient B., born in 1996, was admitted to the center in the acute period of hemorrhage from the fusiform aneurysm of the M2-branch of the middle cerebral artery, which, in turn, was excluded from circulation deconstructive, without neurological deficit in the postoperative period. Three months after the first endovascular treatment the patient was re-admitted to the center with the clinical manifestations of spontaneous subarachnoid hemorrhage. According to multispiral computed tomography and selective cerebral angiography, a fusiform aneurysm de novo of M2-branch of the middle cerebral artery was found, which, in turn, was excluded from circulation deconstructive in two stages. The first attempt at endovascular treatment failed to achieve total fusiform aneurysm de novo occlusion using detachable coils, due to the high risk of intraoperative complications. Ten days after the first stage the patient was taken again. Non-standard technique using balloon-assisted adhesive composition made it possible to achieve complete deconstructive occlusion of fusiform aneurysm de novo from the blood stream and to avoid complications in the form of neurological deficit. The postoperative period proceeded without features. In satisfactory condition the patient discharged under the supervision of a neurologist at the place of residence. The patient underwent 4 control examinations in the form of selective cerebral angiography. Collateral blood flow to the branches of the middle cerebral artery is preserved.

The results of the study of a probiotic sanitaryhygienic product developed on the basis of sporeforming bacteria of the genus Bacillus are presented. Production experiments on treating the udder of cows after milking were carried out at the livestock complex for commercial production of milk in the Republic of Sakha (Yakutia). For the research, two groups of clinically healthy dairy cows aged 3-4 years (52 animals each) were formed. To treat the nipples of cows’ udder of the experimental group, sanitary-hygienic product «Probiodez 3 + 5» was used developed on the basis of the equal combination of bacterial strain Bacillus. subtilis TNP-3 and B. subtilis TNP-5 with a content of 1.5 × 105 CFU/ cm3. Treatment of cows’ udder of the control group after milking was not performed. The effectiveness of sanitation was taken into account by the quantity of mesophyll aerobic and facultative anaerobic microorganisms (QMAFAM), staphylococci and Escherichia on the skin of the nipples of the udder. There was a decrease in the microbial contamination of the nipples of cows’udder with a daily two-time use of the remedy “Probiodes 3 + 5”. The QMAFAM index of the cows of the experimental group on the day 30 of the experiments was 6.8 × 103 COE / cm3 (a decrease by 57.3 times). In the control group of cows, QMAFAM increased by 2.6 times and amounted to 2.9 × 105 COE/ cm3 (42.6 times higher than the indicators in the experimental group). In the experimental group of cows, the number of staphylococci decreased by 4.4 times, Escherichia – by 25.8 times. The use of «Probiodes 3 + 5» helps to decrease the level of QMAFAM, reduce staphylococci and Escherichia, it has also no side effects and does not cause allergic reactions of the nipples skin of cows’ udder. The scientifi c novelty of the development is confi rmed by obtaining a patent of the Russian Federation «Method for the rehabilitation of the udder of cows using strains of bacteria Bacillus subtilis».

The assessment results of 106 samples of spring barley from the collection of the N.I. Vavilov AllRussian Institute of Plant Genetic Resources are presented. The effect of morphometric parameters of their productivity elements on the yield formation and the degree of their correlation is shown. The studies were conducted in 2016–2018 in a collection nursery in the forest-steppe zone of Kemerovo region. During the years of research, the meteorological conditions of the growing season were characterized by an acute moisture defi cit in May and June in 2016 and 2017 (hydrothermal coeffi cient HTC from 0.37 to 0.50) and then by excessive moisture level in 2018 (in June HTC = 2.41, in July HTC = 1.92). A signifi cant excess of yield compared to the standard Biome variety was found in two samples of spring barley from the Czech Republic: Jubilant and Svit (80.33 g) and a sample from Kazakhstan Ilek 1 (103.3 g). Eight spring barley samples showed excess of yield from a unit area compared to the standard variety from 26.6% to 63.0%. As for the complex of valuable features, the following varieties were revealed: Svit (Czech Republic), Azov (Rostov Region), Ilek 1, Ilek 16 (Kazakhstan), Shukran (Krasnodar). The closest relationship was established between the yield of spring barley and the morphometric indicators of the elements of its productivity: the number of productive stems per unit area (r = 0.8728), the biomass of the root system (r = 0.3598), the mass of 1000 grains (r = 0.3273), spike productivity (r = 0.3820). Varieties with the highest degree of economically valuable traits, selected from hybrid populations of VIR, are advisable to use for the breeding process in the soil and climatic conditions of Kemerovo region.

Published: November 2019

This research is presented experimental and numerical investigations of composite concrete-steel plate shear walls under axial loads to predicate the effect of both concrete compressive strength and aspect ratio of the wall on the axial capacity, lateral displacement and axial shortening of the walls. The experimental program includes casting and testing two groups of walls with various aspect ratios. The first group with aspect ratio H/L=1.667 and the second group with aspect ratio H/L=2. Each group consists of three composite concrete -steel plate wall with three targets of cube compressive strength of values 39, 54.75 and 63.3 MPa. The tests result obtained that the increase in concrete compressive strength results in increasing the ultimate axial load capacity of the wall. Thus, the failure load, the corresponding lateral displacement and the axial shortening increased by increasing the compressive strength and the rate of increase  in failure load of the tested walls  was about (34.5% , 23.1%) as compressive strength increased from 39 to 63.3 MPa for case of composite wall  with aspect ratio H/L=1.667 and  H/L=2, respectively. The effect of increasing aspect ratio on the axial load capacity, lateral displacement and axial shortening of the walls was also studied in this study. Compared the main performance characteristic of the testing walls, it can be indicated that the walls with aspect ratio equal to (2) failed under lower axial loads as compared with walls with aspect ratio equal to 1.667 ratios by about (5.8, 12, 15.6 %) at compressive strength (39, 54.75, 63.3 MPa), respectively and experienced large flexural deformations. The mode of failure of all walls was characterized by buckling of steel plates as well as cracking and crushing of concrete in the most compressive zone. Nonlinear three-dimensional finite element analysis is also used to evaluate the performance of the composite wall, by using ABAQUS computer Program (version 6.13). Finite element results were compared with experimental results. The comparison shows good accuracy.
Footing Soil Pressure from Biaxial Loading
Authors: Moffitt Christopher J.
Published: November 2019

A symmetrical isolated rectangular footing with centered biaxial overturning develops soil pressure that shifts to counter balance the loads. The highest soil pressure is at a corner. The objective of this paper is to extend the uniaxial soil pressure solution to include biaxial loads and to document a simple and understandable way to directly calculate the shape of the soil pressure distribution. Another objective is to make the solution suitable for automation. In uniaxial overturning there are two transition shapes, trapezoidal and triangular. In biaxial overturning there are three transition shapes and they form 4, 5 & 6 sided polyhedrons. This analysis calculates those volumes and compares them to the design vertical load to determine the characteristic shape of the soil pressure distribution. The calculation then proceeds to converge on the precise shape and calculate its centroid and moment capacity. Assemblies of tetrahedrons are used to model all of the soil pressure shapes. The advantage of this methodology is that matrix algebra can be used to organize the calculations and make them computationally efficient. The assumed soil pressure and footing dimensions can be adjusted until the calculated moment capacity matches the overturning moment.

Nowadays, due to augmentation of population and expansion of cities and the limitation of fresh water sources in the world, existing water resources cannot meet the human needs. Desalination or reduction of salinity of water through biological methods involves the use of plant species, microorganisms, algae or a combination of them, which can be effective in reducing water salinity. The objective of this study was to investigate the desalination of saline waters by using Dunaliella salina algae. For this purpose, the experiments were carried out as factorial based on completely randomized design. The expected tests were conducted in a laboratory controlled condition for humidity, light and temperature (90 days). During this research, the Electrical Conductivity (EC) was measured daily. The results showed that salt absorption in Dunaliella salina algae was significantly different. High salt absorption was observed in Dunaliella salina at a concentration of 130mS.cm-1. Due to the constant humidity, light and temperature, salt removal from saline water was observed in laboratory conditions. The results of this study indicate that significant reduction of chlorine, sodium and bicarbonate levels were observed using Dunaliella salina algae. According to the results of this study, it seems that reducing salt absorption in algae is due to the use of salt in the metabolism and the growth and proliferation of algae. The absorption process in this study showed that the catch of Dunaliella salina has a good ability to remove salt and can be used as an appropriate suggestion for salt removal from saline water.

Published: November 2019

The objective of research is finding of a possibility economy of rigid pavement weight and volume of material. The subject of the research is a mathematical model of rigid pavement in the form of a multilayer structure on an elastic foundation. The method of a research consists in modeling the behavior of rigid pavement in the form of a set of equations. These equations reflect the change in the stress-strain state of such structures. The system of equations takes into account the geometric nonlinearity of the work of materials and makes it possible to investigate the influence of various parameters on the values of stresses and displacements. Critical force coefficient and stress of shells are calculated by Bubnov-Galerkin. The formation way of the elastic foundation allows modeling the spreading layers with various characteristics. Use of two-layer model allows considering of a surface course and base course of road pavement designing (for example concrete and crushed stone). The graphs show the patterns of change of the stress of rigid pavement when changing the characteristics. The form of rigid pavement allowing to maintain big loadings is exposed to improvement. Findings shows the possibility of optimizing the geometric parameters of the design and achieving the savings in weight and volume of the consumable material.

Currently the Ministry of Construction is responsible for planning and construction of bridges across the country but remote sensing and satellite data are not widely used in the Ministry’s routine process. Although the inspection and monitoring are carried out by the conventional methods, the remote sensing and GIS techniques are available as an alternative way with time and cost saving. From this study, the channel migration in the locations of Ayeyarwady bridges will be analyzed and mapped by identifying temporal changes of channels. Google Earth Engine is used as the primary application in this study and surface water extraction from historical Landsat satellite imagery is done by GEE. River centerline processing and erosion-deposition area identifications are carried out by GIS technique. Study period of each bridge is between 1987 and 2017. Bo Myat Tun Bridge and Ayeyarwady Bridge (Pakokku) are toped in the list with highest migration and erosion-deposition rate according to the study. The goal of this study is to assist the bridge inspections and channel monitoring works by means of remote sensing and GIS techniques which are currently undertaking by Ministry of Construction with conventional techniques.

Maluku is one of the provinces of the eastern part of Indonesia, consisting of 11 regencies. The Maluku branch of Statistics Indonesia reported in 2018 that in 2013–2018 the number of poor people in Maluku's rural areas increased by 1,970. Concurrently, the number of poor people in urban areas decreased by around 6,070 people. This fact showed that development in Maluku Province hadn't been implemented effectively and equally. This study aimed to determine the development priority in Maluku Province using the Analytical Hierarchy Process method. The determination of priorities was based on three aspects in the human development index concept, namely education, health, and economy. Data from Statistics Indonesia on life expectancy, mean years of schooling, expected years of schooling, and per capita expenditure were the indicators were used as the indicators in this study. The results showed that there were 10 regencies with a high level of priority, with the exception being Ambon City, which had a low-level priority. Classification of regencies showed that there was a disparity between them. These findings can help to inform future development designs in Maluku Province.

Authors: Carneiro Mario Rubens
Published: December 2019

Estudos a respeito dos efeitos de coortes sobre preferências por diversos produtos culturais levantaram evidências da existência de um período de maior sensibilidade na vida dos consumidores, no qual se desenvolvem gostos perenes levados por toda a vida. Estas conclusões oferecem a alternativa da segmentação por coortes geracionais e fornecem mais informações sobre as preferências e o comportamento dos consumidores. Este artigo aplica a teoria a um poderoso produto cultural, a teledramaturgia, investigando se as preferências pelos seus ídolos sofrem os efeitos de coorte. Assim também amplia o escopo de estudos anteriores, visando generalizar ainda mais a teoria. Os resultados revelaram consistências com a teoria existente e estudos anteriores, levantando várias interpretações e implicações interessantes para os profissionais de marketing, particularmente para segmentação de públicos e endossos de propagandas.
