Published: April 2018

The article deals with ecological safety, resource saving, economic efficienty in the technologies of wastewater purification from heavy metals ions. It is shown that modern technologies of wastewater purification from such substances need to be improved. А promising way to solve this problem is the production and wide use of carbon sorbents obtained from the waste of processing agricultural raw materials and waste generated at food enterprises. Scientific research is actively carried out in this area. This is due to the possibility of organizing the process of wastewater purification from heavy metal ions in a cheap and effective way. The development of biosorbent production is relevant for Ukraine, as the development of agriculture and food industry is of primary importance. The article presents the results of an analytical review of literary sources on various aspects of the scientific problem. In particular, possible sources of raw materials for the production of biosorbents, classical and modified technologies for their production, mechanisms of biosorption using raw materials with different chemical composition, sorption characteristics of biosorbents, and indicators of the economic efficiency of their production are considered.

Published: April 2018

Aerobic composting is one of the best available technologies for an integrated waste management system in terms of minimizing the anthropogenic impact on the environment, complying with the latest domestic and foreign developments, economic and practical acceptance of the technology. Organic production is rapidly spreading in the world as a holistic system of rational nature management that becomes the basis for the use of modern composting technologies for organic raw materials to obtain a quality product of processing. But composting is characterized by relatively low popularity in comparison with other methods of waste utilization due to a number of its disadvantages, such as a long production cycle and sometimes the unstable quality of a product obtained. Because of this, many studies in the field of solid waste recycling are devoted to methods of accelerating the composting process. This can be achieved in various ways, such as the development of high–performance composting machines and biotic changes (vermiculture, use of specialized crops and biocenoses of microorganisms), or abiotic (temperature, pH, etc.) parameters of the process.The article presents the results of studying the effect of mineral additives on organic waste composting processes, with the aim of its accelerating in mesophilic and thermophilic temperature regimes with controlled parameters. To improve the efficiency of the composting process and compare the features of the processes, the soil was used as a microbiological inoculum, and mineral salts solutions as a mineral additive. The results of the studies allow us to conclude that it is advisable to compost plant waste with a mineral additive, both in the thermophilic and the mesophilic mode. The compost ripening period, with a mineral additive used, is 6 weeks. It is shown that the mineral complex accelerates the composting of the organic constituent of municipal solid waste by 2.2 times in the thermophilic mode, and by 1.4 times under the mesophilic conditions of the composting process, which proves the effectiveness of its use in recycling municipal solid waste to increase the general level of environmental safety.

Authors: Shmatchenko N. , Artamonova M. , Aksonova O. , Oliinyk S.
Published: April 2018

This article presents the results of studies of the properties of marmalade with natural plant cryoadditives during storage for 3 months (90 days). To improve the organoleptic characteristics and antioxidant properties of marmalade, plant additives of cryogenic origin were used, namely cryopastes from quince, apple, carrot, pumpkin, grapes, and cryopowders from rose hips, sea buckthorn, and grapes. It is shown that the use of plant cryoadditives makes it possible to increase the biological value and antioxidant properties of new types of marmalade. For new types of marmalade with cryoadditives, during its shelf life, these properties have not been studied earlier. However, it should be noted that such studies are necessary and relevant for solving the problem of preserving the quality indicators and antioxidant capacity of marmalade with cryoadditives. New kinds of marmalade have high organoleptic characteristics during the whole storage period. It is shown that the storage conditions of marmalade, according to current regulatory documentation, are suitable for new marmalade products, since the physico-chemical and microbiological indicators vary, but remain within acceptable limits. Thus, the moisture content decreases to almost 31%, the acidity rises by 12–16%, compared to freshly prepared samples. The content of reducing substances increases by 30–64%. It is determined that the value of the antioxidant capacity of all the samples developed is much higher – almost 2.3–8 times than the same figure for the control sample. After the storage period, the antioxidant capacity is reduced by 15–35%, but this data also significantly exceeds the antioxidant capacity of the control sample. Storage of marmalade with cryopastes and cryopowders for 90 days is possible, since all the basic physico-chemical, microbiological, and organoleptic indicators at the end of shelf life meet the requirements. Indicators of antioxidant capacity for them also remain at a fairly high level. New technologies of jelly-fruit marmalade with plant cryoadditives have been introduced at 4 enterprises. 2 utility model patents have been received, and regulatory documents have been developed and approved for the manufacture of new jelly products.

Published: April 2018

The analysis and comparative description are carried out of varieties of brewing barley light malt and type 90 hops from domestic and foreign producers, as the main plant raw material that forms the quality of beer. The quality indexes of malt samples and hop pellets have been tested for compliance with applicable standards.The obtained results indicate that the varieties of barley malt are homogeneous grain mass, do not contain moldy and damaged grains, weed impurities, have a color from light yellow to gray to yellow. Ten samples of malt of various grades for beer production have been studied in terms of mass fraction of moisture (3.2–3.7%), mass fraction of extract in dry matter of fine malt (82.4–87.5%), degree (0 9–1.2%), the mass fraction of protein substances in dry matter of malt (9.1–10.1%), the Kolbach index (39.1–40.2%), the amount of nitrogenous substances (0.70–0, 74%). It has been established that the quantitative content of β-glucans significantly differs in different varieties: the minimum amount is contained in the malt Château Wien, the maximum is Pilsner Weyermann and Munich.According to the research results, it has been established that barley malt varieties have a pronounced malt aroma and sufficient fermentative activity and can serve as the base in the mash in the production of beer. It is proved that malt samples have an acceptable amount of toxic substances and radionuclides that will not affect the quality of the finished product. In assessing the quality of varieties of hop pellets by organoleptic indicators, the mass fraction of moisture and α-acids, it is established that the samples have the values of the indicators within the permissible limits. The samples have a cylindrical shape of different hues and approximately the same size; pure hop aroma, without an off-aroma; the color on the surface and at the boundary of the pellets meets the requirements of the standard. The mass fraction of α-acids is in the range from 3.0 to 12.7 %. It is revealed that bitter and aromatic hops are used for pellet production. The samples Magnym and Hallertau Perle are classified as bitter varieties. Hop pellets of the varieties Premiant and Sladek are bitter and aromatic.According to the results of the determination of quality indicators, the following ones have been identified as the best: malt – Munich, Pilsner, Carabohemian, hop pellets – Bramling Cross, Mandarina Bavaria and Magnym. The proposed varieties of malt and hops allow obtaining beer with high organoleptic characteristics, colloidal stability and expand the range of the industry by creating new varieties to meet the needs of the consumer.
MASS TRANSFER IN FERMENTATION PROCESSES
Authors: Shevchenko A. , Sokolenko A. , Stepanets O. , Bilyk O.
Published: April 2018

The peculiarities of anaerobic fermentation processes with the accumulation of dissolved ethyl alcohol and carbon dioxide in the culture media are considered in the article.The solubility of CO2 is limited by the state of saturation in accordance with Henry’s law. This, with all else being equal, limits the mass transfer on the interface surface of yeast cells and the liquid phase of the medium. A phenomenological model of the media restoration technologies based on the unsaturation index on СО2 is developed. It is shown that this restoration in the existing technologies of fermentation of sugar-rich media occurs, to a limited extent, in self-organized flow circuits, with variable values of temperatures and hydrostatic pressures, due to the creation of unsaturated local zones.It is shown that increasing the height of the media in isovolumetric apparatuses leads to an increase in the levels of flow circuits organization and to the improvement of the desaturation and saturation modes of the liquid phase and intensification of mass transfer processes. Among the deterministic principles of restoring the saturation possibilities of the media, there are forced variables of pressures with time pauses on their lower and upper levels. In such cases, the possibilities of short-term intensive desaturations in full media volumes, the restoration of their saturation perception of CO2, and the activation of fermentation processes are achieved. This direction is technically feasible for active industrial equipment.The cumulative effect of the action of variable pressures and temperatures corresponds to the superposition principle, but at the final stages of fermentation, the pressure and temperature values are leveled, so the restoration of the unsaturation state slows down to the level of the bacteriostatic effect. The possibility of eliminating the disadvantages of the final stage of fermentation by means of programmable variable pressures is shown

Published: April 2018

The possibility of muropeptides obtaining of peptidoglycans of Lactobacillus delbrueckii subsp. Bulgaricus B-3964 cell walls by the combination of the use of autolytic processes and enzyme treatment of biomass with the participation of lysozyme and papain has been considered. It has been established that the most significant autolytic changes in biomass occur in the application of high-temperature processing (90°C for 30 minutes) in the final stage of the logarithmic phase of bacterial growth. Thus, after eighth hour of biomass incubation at 37°C, the amino acid content in the culture medium was 1.8 mg/cm3, and at 90°C it was 5.7 mg/cm3. In order to further destruction of biomass autolysate and obtaining of low molecular weight peptidoglycan fragments, the process of its enzymatic hydrolysis was studied with lysozyme and papain separately and at their combination. The highest content of low molecular weight peptides in the reaction medium occurred at enzymatic hydrolysis of biomass Lactobacillus delbrueckii subsp. Bulgaricus B-3964 by the composition of enzymes at a ratio of lysozyme : papain 1:2. At a concentration of enzymes 10 mg/cm3, the content of low molecular weight peptides was 7.2 mg/cm3 after eighth hour of incubation of the reaction mixture. The results of studies have been shown that the efficiency of enzymatic hydrolysis of autolysates is much higher. Thus, the amount of low molecular weight peptides in the hydrolysate obtained by processing the autolysate with the composition of lysozyme : papain 1:2 at an enzymes concentration 10 mg/cm3 and the duration of the process for 8 hours by 36% higher than for similar hydrolysis parameters without the use of the process of autolysis.The method of gel chromatography was proved that in the hydrolysate there are fractions of protein compounds with a molecular weight in the range of 70–90 kDa, 30–40 kDa and 294–650 Da. The molecular weight of the latter fraction corresponds to the mass of the muramyl dipeptide. The presence of muropeptides was proved by reaction with the Anthron reagent.
An Improved Local Descriptor based Object Recognition in Cluttered 3D Point Clouds
Authors: Liu Xiaoni , Lu Yinan , Wu Tieru , Yuan Tianwen
Published: April 2018

Object recognition in three-dimensional point clouds is a new research topic in the field of computer vision. Numerous nuisances, such as noise, a varying density, and occlusion greatly increase the difficulty of 3D object recognition. An improved local feature descriptor is proposed to address these problems in this paper. At each feature point, a local reference frame is established by calculating a scatter matrix based on the geometric center and the weighted point-cloud density of its neighborhood, and an improved normal vector estimation method is used to generate a new signature of histograms of orientations (SHOT) local-feature descriptor. The geometric consistency and iterative closest point method realize 3D model recognition in the point-cloud scenes. The experimental results show that the proposed SHOT feature-extraction algorithm has high robustness and descriptiveness in the object recognition of 3D local descriptors in cluttered point-cloud scenes.
Control-Scheduling Codesign for NCS based Fuzzy Systems
Authors: Mendez-Monroy Paul Erick , Sanchez Dominguez Israel , Bassam Ali , Tzuc Oscar May
Published: April 2018

In the present paper, a fuzzy codesign approach is proposed to deal with the controller and scheduler design for a networked control system which is physically distributed with a shared communication network. The proposed fuzzy controller is applied to generate the control with different sampling-actuation periods, the configuration supposes a strict actuation period disappears the jitter. The proposed fuzzy scheduling is designed to select the sampling-actuation period. So, the fuzzy codesign reduces the rate of transmission when the system is stable through the scheduler while the controller adjusts the control signal. The fuzzy codesign guarantees the stability of all the system if the network uncertainties do not exceed an upper bound and is a low computational cost method implemented with an embedded system. An unstable, nonlinear system is used to evaluate the proposed approach and compared to a hybrid control, the results show greater robustness to multiple lost packets and time delays much larger than the sampling period.

How Much has Wealth Concentration Grown in the United States? A Re-Examination of Data from 2001-2013
Authors: Bricker Jesse , Henriques Alice , Hansen Peter
Published: April 2018

Well known research based on capitalized income tax data shows robust growth in wealth concentration in the late 2000s. We show that these robust growth estimates rely on an assumption---homogeneous rates of return across the wealth distribution---that is not supported by data. When the capitalization model incorporates heterogeneous rates of return (on just interest-bearing assets), wealth concentration estimates in 2011 fall from 40.5% to 33.9%. These estimates are consistent in levels and trend with other micro wealth data and show that wealth concentration increases until the Great Recession, then declines before increasing again.
A Day Late and a Dollar Short: Liquidity and Household Formation among Student Borrowers
Authors: Goodman Sarena , Isen Adam , Yannelis Constantine
Published: April 2018

The federal government encourages human capital investment through lending and grant programs, but resources from these programs may also finance non-education activities for students whose liquidity is otherwise restricted. This paper explores this possibility, using administrative data for the universe of federal student loan borrowers linked to tax records. We examine the effects of a sharp discontinuity in program limits—generated by the timing of a student borrower’s 24th birthday—on household formation early in the lifecycle. After demonstrating that this discontinuity induces a jump in federal support, we estimate an immediate and persistent increase in homeownership, with larger effects among those most financially constrained. In the first year, borrowers with higher limits also earn less but are more likely to save; however, there are no differences in subsequent years. Finally, effects on marriage and fertility lag homeownership. Altogether, the results appear to be driven by liquidity rather than human capital or wealth effects.

A NECESSIDADE DO REGISTRO DE NASCIMENTO BIOMÉTRICO DA PARTURIENTE E DO NASCITURO
Authors: Paz Jurandir Bezerra
Published: April 2018

O presente artigo tem por objetivo dispor sobre a necessidade do registro de nascimento biométrico da parturiente e do nascituro para conferir às parturientes maior segurança ao registrar o bebê ou a criança. Uma mulher pode ir a um cartório e dizer que deu a luz em casa sem ajuda de uma parteira e obter a DNV (declaração de nascido vivo) e registrar o bebê como sendo seu. A DNV e o registro de nascimento poderiam ser documentos mais seguros e precisam de mudanças. O cadastro biométrico é um mecanismo eficaz na comparação de características das pessoas e na prevenção de que uma pessoa se passe por outra porque o mecanismo detecta as diferenças. O tema foi escolhido em razão das falhas de segurança do sistema de registro de nascimentos e das consequências que os nascituros e crianças estão sujeitos, como adoção à brasileira, a troca, a venda, o tráfico para exploração sexual, trabalho escravo, a venda de órgãos etc.
E quando não houver ruínas?
Authors: Robalinho Roberto
Published: April 2018

Resumo: Em junho de 2013 as ruas do Brasil foram tomadas por manifestantes. Se os protestos surpreendem e desestabilizam a realidade social com novas formas de ação política, esses processos tomam corpo através de uma relação contígua e simultânea com as imagens. Como podemos olhar para a relação liminar entre a multidão nas ruas e as telas para acessar a produção política e subjetiva de junho de 2013? Benjamin propõe um olhar sobre a história que não seja descritivo, linear e triunfalista, mas lacunar, sintomático, disruptivo, intensificado e capaz de atualizar as forças políticas no presente. Mais do que olhar o passado, Benjamin deseja intervir no presente. É a partir dessa provocação que olhamos as imagens de junho de 2013, mais especificamente para uma série de planos sequência que foram produzidos durante a noite de 17 de julho de 2013 quando o Bairro do Leblon foi tomado por manifestantes e barricadas em chamas. Porque o plano sequência e de que forma esta unidade de linguagem cinematográfica incorpora uma experiência das ruas insurgentes?Palavras-chaves: junho de 2013; imagem; história; produção política; produção subjetiva; plano sequência.Abstract: In June 2013 Brazilian streets were overtaken by protests. If new forms of political action capable of disrupting social reality were invented, this process was lived through a contiguous and simultaneous relation with images. How can we access June’s 2013 political and subjective production through the liminal relation between its images and the crowd on the streets? Benjamin proposes an approach to history that is not explanatory, linear and triumphant, on the contrary is fragmented, symptomatic, disruptive, intensified and able to bring forth political forces in the present. More than looking at the past, Benjamin desires to intervene in the present. This is a starting point to look at June 2013 images, more specifically, to a series of long shots that were produced in 2013 during the night of the 17 of July when the posh neighborhood of Leblon was overwhelmed by protesters and blazing barricades. Why the use of long shots and how does this unity of cinematic discourse express an experience of the insurgent streets?Keywords: June 2013; image; history; political production; subjective production; long shot.
Workarounds in the Danish Health Sector – from Tacit to Explicit Innovation
Authors: Dupret Katia , Friborg Bjarke
Published: April 2018

Drawing on actor-network theory (ANT) and science and technology studies (STS) and on ethnographic research in Denmark, we argue that how health care workers work around technologies can be conceptualized as tacit innovation – that is, practical expressions of active encounters with the complexity of work situations and therefore potential sources of sustainable and innovative work practices. The concept ‘invisible work’ is used to show that ‘what counts as work’ is bound up with technologies that are not neutral. Technologies, professionals, and patients implicitly co-constitute innovation processes, and we argue that in order to understand the potential of tacit innovation among health care workers, one must revisit the dichotomy between technology producers and technology end-users. The aim and contribution of this paper is thus to attempt to revitalize the discussion about technology workarounds as initiatives of tacit innovation, thus adding to the theoretical conceptualization of invisible work when technologies are used in health care work.
Quality Development in Health Care: Participation vs. Accreditation
Authors: Simonsen Jesper , Hertzum Morten , Scheuer John Damm
Published: April 2018

For more than a decade, quality development in the Danish health care sector has been managed with an accreditation system known as the Danish quality model (DQM), shaping the strategy for how to align work organization with technology use. In this article, we introduce a participatory design approach, known as effects-driven information technology development (EDIT), and discuss how this approach may contribute to a new quality-assurance program for the Danish health care sector. Our purpose is to demonstrate how accreditation, which focuses on processes and standards, needs to be supplemented and balanced with participatory approaches that allow for local experimentation and implementation of high-quality outcomes. We describe accreditation and participatory design as two approaches to reconfiguring and aligning work organization and technology; further, we emphasize the differences in each approach’s strategy and application.

ON VARIOUS TECHNIQUES IN OFDM AND GFDM: A SURVEY
Authors: Kumar Abhishek
Published: April 2018

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation that divides the available spectrum into a finite number of carriers and applied into a digital transmission system. But it has some drawbacks such as sensitivity in inter-carrier interference, high peak to average power ratio and insufficient cyclic prefix in spectrum. These drawbacks may be reduced by a technique known as Generalized Frequency Division Multiplexing (GFDM). In the present scenario, it is a high speed multi-carrier multiplexing data transfer scheme for the cellular network. This paper deals with a comparison between OFDM and GFDM and focuses on various techniques in OFDM and GFDM.
A interface entre Saúde Mental e Vulnerabilidade Social

Published: April 2018

Esta pesquisa objetivou conhecer o entendimento dos profissionais da Atenção Primária a Saúde, de uma unidade de saúde num município do interior de SC, sobre a interface entre Saúde Mental e Vulnerabilidade Social. O projeto de pesquisa foi apreciado pelo CEP/UNIPLAC, com parecer aprovado nº 721.689. A coleta de dados aconteceu por meio de entrevista semiestruturada, com aplicação do TCLE, com dez profissionais de equipes de ESF e NASF. Os dados, tratados por meio de análise de conteúdo, indicaram que os profissionais de saúde compreendem a saúde mental integrante da saúde “geral” e acreditam que a falta de educação formal, desconhecimento dos serviços da rede, estresse e desemprego são fatores que influenciam no sofrimento psíquico. Quanto à vulnerabilidade social, relacionaram com a questão econômica e a descreveram como falta de condições de saneamento básico, moradia, escolaridade e autonomia. Os profissionais veem relação entre Saúde Mental e Vulnerabilidade Social, pois, a exposição das pessoas a situações de vulnerabilidade social e risco de sofrimento psíquico não é resultante apenas de aspectos individuais, mas, coletivos. Percebe-se que o cuidado em saúde mental aparece fragmentado; contudo, os profissionais de saúde têm buscado considerar novas estratégias para lidar com esta, bem como em relação à vulnerabilidade social, através de um trabalho multiprofissional, voltado às necessidades das famílias. Ainda é evidente uma prática assistencialista, quando se faz necessário criar condições para que estas famílias se conscientizem e se tornem protagonistas de suas vidas.

Authors: Rumapar Ladyna , Mustokoweni Sjahjenny , Rahniayu Alphania
Published: April 2018

Colorectal carcinoma has high morbidity and mortality rate worldwide, in which over 90% are adenocarcinoma. Colorectal carcinoma is one of the most cancer that metastasize to the lymph node. Angiogenesis have an important role in tumor growth and metastasis. Hypoxia is the trigger factor for angiogenesis. Hypoxia induced factor-1 (HIF-1) is one critical protein directly reacting to hypoxia. HIF-1alpha, a HIF-1 subunit, is an important regulator of angiogenesis. This study analyzed HIF-1a expression in colorectal adenocarcinoma with and without regional lymph node metastasis. This study was to prove that HIF-1a has a role in regional lymph node metastasis in colorectal adenocarcinoma. An analytical observational study was conducted on thirty formalin fixed paraffin-embedded colorectal adenocarcinoma tissues from Anatomic Pathology Laboratory of Dr. Soetomo Hospital. Detection of HIF-1alpha expressions were performed with immunohistochemistry method, using HIF-1alpha antibody. It were statistically analyzed using Mann-Whitney and Kruskal- Wallis methods.

Mammary Serine Protease Inhibitor (maspin) is a tumor suppressor gene, a member of the serine protease inhibitor (serpin) family that works by inhibiting motility of cell movement, invasion and metastasis. Maspin expression is expected to be a prognostic factor as well as a predictive factor in mammary tumors. However, in some recent studies, maspin has a variety of expressions. Although it is known that no maspine appears as an indicator of tumor progression and metastasis, recent study has shown that maspine expression is associated with an aggressive phenotype of breast cancer and with a poor prognosis. Correlations between maspine expression and poor prognosis have also been reported in pancreatic, ovarian, thyroid, bladder and lung cancers. Knowledge of the expression and role of this maspin as well as its relationship with the pathogenesis of breast invasive ductal carcinoma is still small. The aim of this study was to look at differences in maspin expression in breast-invasive ductal carcinoma of stage IIA and stage IIIB groups. This research method used analytic observational research with cross sectional approach. The samples were invasive carcinoma of NST paraffin at the Department of Anatomic Pathology of Dr Soetomo Hospital, Surabaya, from January to December 2015. Thirty samples were divided into two groups, namely stage IIA and stage IIIB groups and immunohistochemical examination with maspin antibody was carried out. The difference of maspin expression in stage IIA and stage IIIB was analyzed using Mann-Whitney statistic test. There were significant differences in maspin expression between stage IIA and stage IIIB groups, where stage IIA has a high maspin expression rather than stage IIIB.

Carbapenemase-producing Escherichia coli (E. coli) has caused trouble in therapeutic antibiotic selection. Carbapenemase screening procedure in laboratories is usually based on inacurate semi-automatic system. Confirmation and classification of carbapenemases according to Ambler can be done with combination of phenotypic methods, i.e., Modified Hodge Test (MHT), Sodium Mercaptoacetic Acid (SMA), and 3-Aminophenylboronic Acid (PBA). This study aimed to compare profiles of carbapenemase-producing E. coli which were confirmed and classified phenotypically with the genotypic profiles. E. coli isolates from urine specimens which were potential as carbapenemase-producers according to semi-automatic system BD Phoenix were phenotypically tested with MHT, SMA, and PBA. Isolates were grouped as carbapenemase-producers and non carbapenemase-producers. Phenotypic carbapenemase-producer isolates were classified based on Ambler criteria. All isolates were then tested with Polymerase Chain Reaction (PCR) for the presence of OXA-48, IMP1, IMP2, GES, VIM, NDM, KPC genes. Out of 30 isolates, 6 isolates (20.0%) were MHT positive, and 25 isolates (83.3%) were SMA positive, which indicated that most isolates produced were carbapenemase Ambler B. PCR confirmed 12 isolates (40.0%) had VIM gene which were classified as carbapenemase Ambler B. Phenotypic confirmatory test had 100% sensitivity and 22.2% specificity. Classification with phenotypic confirmatory test had 91.7% match with PCR. Phenotypic confirmatory test detected more carbapenemase than PCR. This low specificity may be caused by inappropriate use of diagnostic gold standard. PCR should not be used for routine carbapenemase confirmation because of vast diversity of carbapenemases. Phenotypic confirmatory test can classify carbapenemase according to Ambler classification.

Folic acid contains 5-methyltetrahydrofolate (5-MTHF), one of antioxidants that can be used to inhibit reaction caused by cigarette smoke exposure. Folic acid is able to inhibit the levels of Reactive Oxygen Species (ROS) so as to reduce the occurrence of neuronal apoptosis. The objectives of this study was to determine the effect of folic acid intake during pregnancy whose mother was exposed to cigarette smoke on brain neurons apoptosis index and quantity of mice (Mus musculus) offspring. This study was an experimental laboratory study with posttest-only control group design. The subjects were 24 female mice divided into 4 groups consisting of one control group and three treatment groups. Sampling used simple random sampling, each group consisting of 6 animals. Control group 1 was not given treatment during pregnancy, group 2 was given with folic acid orally on days 0-17 of gestational age as much as 0.06 mg/day/mice. Group 3 was given with cigarette smoke exposure on days 7-17 of gestational age, amounting to 2 cigarettes/day. Group 4 was given with cigarette smoke exposure on days 7-17 of gestational age, amounting to 2 cigarettes/day and folic acid orally on days 0-17 of gestational age as much as 0.06 mg/day/mice. The result showed significant differences in all variables. In neurons apoptosis index, there were significant differences between groups 1 and 3, groups 2 and 3, groups 3 and 4, significant differences in the quantity of neurons between groups 1 and 3, groups 2 and 3, groups 2 and 4. The study concluded that there were significant difference in neural apoptosis index between all groups, and there were also significant differences in the quantity of neurons between all groups.

This study aimed to determine the effects of arak bali on the fragmentation of spermatozoa and testosterone in rats (Rattus norvegicus). This study used 24 rats (170-200 g), divided into four groups: one control and three treatments (receiving arak bali containing 40% alcohol as much as 0.1 and 0.5 mL and synthetic alcohol (40%) as much as 0.1 mL, for 45 days). The observation of DNA fragmentation was done using acridine orange staining and the measurement of testosterone level used ELISA method. The results showed that the provision of arak bali in experimental animals increased the occurrence of spermatozoa DNA fragmentation. The higher the volume of arak bali given, the higher the fragmentation of spermatozoa DNA. The administration of arak bali also decreased testosterone level. The higher the volume of arak bali given, the lower the rats' testosterone level.

Methyldopa is the first-line drugs to treat hypertension in pregnancy. It can decrease blood pressure in preeclampsia by affecting a2-adrenoreceptors in central nervous system. However, it could also act by decreasing  production of sFlt-1 antiangiogenic protein levels involved in the pathophysiology of hypertention  in preeclampsia. The purpose of this study was to analyze methyldopa therapy on sFlt-1 antiangiogenic levels in the plasma of pregnant women with severe preeclampsia at the Obstetric Departement, Haji Hospital, Surabaya. This was a prospective study with observational cross-section study design. The sFlt-1 angiogenic levels were observed before and after (48 hours) methyldopa administration in severe preeclampsia patient with or without complications in the period of August to October 2016. Patient received methyldopa 250 mg or 500 mg, three times a day for clinical indications according a standard protocol. The study was approved by the ethical committee of Haji Hospital, Surabaya. There were 19 patients with preeclampsia who met the inclusion criteria, showed a decrease in the levels of sFlt-1 before and 48 hours after methyldopa therapy. Levels of sFlt-1 before methyldopa therapy in a dose of 250 mg was 10.15±10.00 (2.55-34.70) ng/ml and after therapy 8,37±9,20 (0.72-9.20) ng/ml, with a percentage decrease 17.54%. sFlt-1 levels before methyldopa therapy in a dose of 500 mg was 8.05±7.07 (2.55-20.76) ng/ml, after  therapy 4.50±2.90 (2.19-9.95) ng/ml, with a percentage decrease 44.16%. Methyldopa therapy could decrease sFlt-1 levels of antiangiogenic factor in patients with severe preeclampsia.

Authors: Perdhana Fajar , Purnomo Herdono
Published: April 2018

Right ventricular dysfunction and failure receive much less attention than the left ventricular failure. Right ventricular dysfunction or failure is associated with increased mortality rates in cardiac surgery, surgical cases other than cardiac surgery and also in patients treated in the ICU. The purpose of this article review was to describe the anatomy, physiology and pathophysiology of right ventricular failure, its detection and diagnosis, and management considerations from anesthetic point of view, including preoperative, intraoperative and postoperative stages. Cardiac surgery may result in right ventricular failure. For example, 0.1% post cardiotomy patients experience severe right heart failure and require long-term inotropic support, and so do 2-3% of post-transplant patients, and 20-30% of patients installed with instrument in his left heart. Therefore, anesthesiologists play a major role in perioperative and postoperative intensive care and are obliged to comprehend the nature of right ventricular dysfunction and failure so as to carry out early detection, prevent and manage patients with right ventricular dysfunction.
An Assessment of Wind Power Generation Potential of Built Environment Wind Turbine (BEWT) Systems in Fort Beaufort, South Africa
Authors: Manyeredzi Terrence , Makaka Golden
Published: April 2018

The physical and economic sustainability of using Built Environment Wind Turbine (BEWT) systems depends on the wind resource potential of the candidate site. Therefore, it is crucial to carry out a wind resource assessment prior to deployment of the BEWT. The assessment results can be used as a referral tool for predicting the performance and lifespan of the BEWT in the given built environment. To date, there is limited research output on BEWTs in South Africa with available literature showing a bias towards utility-scale or conventional ground based wind energy systems. This study aimed to assess wind power generation potential of BEWT systems in Fort Beaufort using the Weibull distribution function. The results show that Fort Beaufort wind patterns can be classified as fairly good and that BEWTs can best be deployed at 15m for a fairer power output as roof height wind speeds require BEWT of very low cut-in speed of at most1.2ms−1.
Moving Source Depth Estimation Using a Horizontal Line Array in Shallow Water Waveguides

Published: April 2018

In this study, a matched-mode autoregressive source depth estimation method (MMAR) based on autoregressive (AR) wavenumber estimation is proposed for a moving source in shallow water waveguides. The signal original frequency and the environmental parameters, namely, the sound speed profile and bottom properties are known as a prior knowledge. The mode wavenumbers are estimated by the AR modal wavenumber spectrum. On the basis of the mode wavenumber estimation, the mode amplitudes can be estimated by the wavenumber spectrum that is obtained by generalized Hankel transform. The source depth estimation is determined by the peak of source depth function wherein the data mode best matches the replica mode that is calculated using a propagation model. Compared with other methods of moving source depth estimation, the proposed method exhibits a better performance in source depth estimation under low signal-to-noise ratio or the small range span. The selection of horizontal line array depth is illustrated by simulation and normal mode theory in details.
