Authors: Milosavljević Srđan , Milić Dejan , Trajković Slaviša , Spalević Petar , Milosavljević Bojana
Published: December 2017

In this paper macrodiversity reception with macrodiversity selection combining (SC) receiver and two microdiversity MRC receivers operating over shadowed multipath fading channel is studied. Received signal experiences  short term fading and correlated Gamma long term fading resulting in system performance degradation. Level crossing rate (LCR) of η-μ random process and level crossing rate of signals at outputs of microdiversity MRC receivers are efficiently calculated. By using these derived formulas, level crossing rate of macrodiversity SC receiver output signal process is calculated. By using this result, average fade duration (AFD) of the proposed wireless communication system can be calculated. The influence of  η-μ  short term fading severity parameter, Gamma long term fading severity parameter and Gamma long term correlation coefficient on level crossing rate is analysed and studied.
MIGRATION AS A FACTOR OF CHANGING THE ECONOMIC AND DEMOGRAPHIC PROFILE OF THE EUROPEAN UNION
Authors: Đorđević Dejan Ž. , Šantić Danica
Published: December 2017

In the age of raising global migration flows and increased mobility of the labour force in the world, there is a need to understand the main determinants of this phenomenon and to direct the focus of migration research to the various  challenges it brings. This is a very important theme, especially in Europe, because 2014 and 2015 were the years of the highest number of immigrants, since WWII. Migrants are economic migrants and refugees, but in unique term they are asylum seekers as they want to stay, live and work in EU countries. Their population structure is quite different from that of EU population: they are young and in optimum reproductive and working age. Is that going to change not only quantitative, but also qualitative characteristics of population living in EU countries which are facing population decline or stagnation, low fertility rate, ageing and lack of labor force? Can we expect the redistribution of EU population due to intensive migration flows in certain countries, or a change in religious structure of the continent? Those are the questions of great importance because the migration flows today are shaping the future of EU population.

DEIXIS AND PERSONHOOD: A NEW PHILOSOPHICAL ACCOUNT
Authors: Vidanović Djordje
Published: December 2017

This paper claims that deixis is over and above a semantico-pragmatic phenomenon, and that it should be analyzed primarily epistemologically and ontologically. Most mainstream accounts of deixis in language simply overlook this point and emphasize the fact that although deixis is more attentional and intentional, it still remains elusive for any semantic and pragmatic framework. Our paper attempts to pave the way for a treatment of deictic phenomena that is based on the notion of ‘personhood’, i.e. on the pre-reflective perception of space-time, which is, furthermore, one of the basic tenets of intersubjectivity in human cognition. This is evident as lived space is deeply intertwined with deixis, or, if one wishes so, the other way round. It seems obvious that constant shifts of personal subjectivity (dependent on contingent intersubjectivity) undermine the rationalist and empiricist standpoints about there being one monolithic percept called 'reality'.

Authors: Radusin-Bardić Nataša
Published: December 2017

En français et en serbe, l’expression de l’espace dans l’interrogation partielle directe peut revêtir différentes formes, en fonction des concepts spatiaux concernés. Nous nous proposons de comparer les adverbes interrogatifs de lieu exprimant les relations spatiales de type statique (la localisation), ainsi que ceux exprimant les relations spatiales de type dynamique (la destination, le point de départ, le point d’arrivée et l’itinéraire). Notre recherche sera fondée sur une analyse contrastive de l’emploi des adverbes interrogatifs exprimant des concepts spatiaux dans plusieurs ouvrages dramatiques écrits en français et en serbe et traduits dans une de ces deux langues. À part l’aspect sémantique des relations spatiales, notre analyse portera également sur les aspects morphosyntaxique et sociolinguistique des formes interrogatives correspondantes.
UNE APPROCHE PRAGMATIQUE DE L’ANALYSE DU DISCOURS ET SON APPLICATION À LA DIDACTIQUE DU FRANÇAIS SUR OBJECTIF SPECIFIQUE
Authors: Živković Danijel
Published: December 2017

Aujourd’hui, la communication est devenue une composante essentielle du travail et les compétences communicatives sont recherchées pour la majorité des postes de travail. La qualité des interactions est d’une grande importance pour améliorer la performance des entreprises. Étant donné que les compétences pragmatiques représentent l’un des éléments indispensables des compétences communicatives générales, notre intérêt est de révéler la manifestation de certaines caractéristiques pragmatiques du discours. Comment une approche pragmatique de l’analyse du discours peut contribuer à la didactique du français sur objectif spécifique (FOS)? La pragmatique vise à comprendre dans quelle mesure les échanges verbaux dépassent un simple échange d’information et influencent l’interlocuteur vers une action ou vers un changement de comportement, d’attitude, de la croyance, de la valeur, etc. Alors, une approche pragmatique de l’analyse du discours devrait décrire les éléments discursifs dans le discours, tels que l’organisation et la structuration des phrases, l’articulation des propositions dans le texte, l’organisation thématique et logique, la cohérence et la cohésion, la construction de l’argumentation etc. À cet effet, nous  analyserons un corpus constitué des phrases issues du discours économique et commercial.
CRITICAL REVIEW OF THE SECURITY MEASURE OF THE RESTRAINT TO APPROACH AND COMMUNICATE WITH THE INJURED PARTY UNDER ARTICLE 89a OF THE CRIMINAL CODE OF SERBIA
Authors: Ćorović Emir , Šemović Aladin
Published: December 2017

In this paper, the authors analyze the security measure involving the restraint to approach and communicate with the injured party under Article 89a of the Criminal Code of Serbia, which was introduced by legislative changes and amendments in 2009. Although this criminal sanction has been part of the domestic criminal legislation for seven years, there are serious legislative deficiencies associated with its regulation. Namely, the positive criminal law of the Republic of Serbia does not regulate the consequences of the act if the convicted offender violates this restraint, nor does it envisage the rules for the execution of this security measure. This can cause serious problems in imposing and applying the relevant criminal sanction. The corresponding data show that courts use this measure to a much lesser extent every year. Thus, the authors give suggestions de lege ferenda to remove the existing restraining order from the system of security measures and to envisage it as one of the obligations under a suspended sentence with supervision.
CRIMINOGENIC INFLUENCE OF PENITENTIARY INSTITUTIONS
Authors: Mirić Filip
Published: December 2017

Referral to serve a sentence of imprisonment in a penitentiary institution is a very stressful experience for all convicted offenders. They are obliged to put an end to their former lifestyle and continue living in a penal institution of a closed type, governed by strict rules of conduct and featuring very diverse population of inmates. Due to the loss of freedom, many convicts are deprived of numerous privileges they used to have outside prison. In reaction to these “deprivations”, they commit new crimes while serving their prison sentences. For this reason, time spent in prison can be an important criminogenic factor. In the first part of the paper, author discusses the forms of deprivation in penitentiary institutions and their impacts on prisoners’ life. Then, the author points out to the criminogenic impact of the prison environment and the necessity to conduct empirical research in this area. Finally, the author underscores the need to find effective measures to reduce the criminogenic impact of the prison environment and turn penitentiaries into facilities for genuine rehabilitation and re-socialization of prisoners.
THE GHRELIN SYSTEM; BEYOND THE ROLE IN ENERGY HOMEOSTASIS
Authors: Šaranac Ljiljana , Gucev Zoran
Published: December 2017

The fascinating story of ghrelin started more than 30 years ago with the discovery of synthetic (non-natural) growth hormone (GH) releasing peptides. Scientists were searching for a novel peptide, ligand of orphan GH secretagogue receptor. The discovery of ghrelin is a typical example of reverse pharmacology. The new peptide quickly attracted a lot of attention by its pleiotropic nature, and provoked a burst of new enthusiasm among scientists and clinicians. Ghrelin is mainly produced in the stomach from a distinct group of endocrine cells located within the gastric oxyntic mucosa. It acts as hunger signal and long-term body weight regulator. But, ghrelin is much more than just a natural orexigenic factor and GH secretagogue. It exerts major peripheral endocrine and non-endocrine actions, and it has a role in learning and memory, glucose homeostasis, immunity, cardio protection, fertility and addiction. Exploring the actions of ghrelin and ghrelin agonists and receptor antagonists or reverse agonists could establish new treatment options for so far incurable diseases.

Tourism is an important asset to regional income and a place of creativity promote the region characteristics. This study aims to analyze persuasive communication strategy conducted by Government, analyzing the communication barriers that occur in the process of forming a tourism conscious society, and purpose the mode of persuasive messages and effective communication media designed to build a tourism conscious society. This study uses a qualitative approach to get the facts from the symptoms that exist and seek information factually. The results show the main persuasive communication strategy undertaken by the government is forming a ‘pokdarwis’ (tourism awareness group). However, this strategy can still be used in various forms, such as: pokdarwis has not acted as an agent of change, unclear tasks distribution in pokdarwis group, un-maximized media, uncontinuity press release, and no synergy among stakeholders. A persuasive message form that can be designed to maximize this communication strategy can be a one-sided and two-sided message. The good government and groups that have been formed this hopefully can use the media consistently so that messages can reach various layers of society. Media that could be matches with the target audience were print media media, outdoor media, group communication media, personal communication channels and internet. Pariwisata merupakan asset yang sangat penting dalam menyumbang terhadap pendapatan daerah dan ajang kreativitas untuk memperkenalkan ciri khas daerah. Untuk itu, penting strategi komunikasi persuasif sebagai faktor penarik kunjungan wisatawan. Penelitian ini bertujuan menganalisis strategi komunikasi persuasif yang dilakukan oleh Pemerintah Kota Padang, hambatan komunikasi dalam proses pembentukan masyarakat sadar wisata, dan menawarkan pesan persuasif dan media komunikasi efektif yang dapat dirancang untuk membentuk masyarakat sadar wisata. Penelitian ini menggunakan pendekatan kualitatif untuk memperoleh fakta-fakta dari gejala-gejala yang ada dan mencari keterangan secara faktual. Hasil penelitian menunjukkan strategi komunikasi persuasif utama yang dilakukan oleh pemerintah berupa pembentukan pokdarwis (kelompok sadar wisata). Strategi ini masih menemui berbagai hambatan dalam pelaksanaannya, seperti: pokdarwis belum bertindak sebagai agent of change, tidak duduknya tugas di kelompok pokdarwis, media yang belum dimaksimalkan, tidak adanya kontinuitas press release, dan tidak adanya sinergi antar stakeholder. Bentuk pesan persuasif yang dapat dirancang untuk memaksimalkan strategi komunikasi ini bisa berupa one-side issue dan two-side issue message.

Authors: Brouwer Tom F. , Vehmeijer Jim T. , Kalkman Deborah N. , Berger Wouter R. , van den Born Bert-Jan H. , Peters Ron J. , Knops Reinoud E.
Published: December 2017

OBJECTIVE

The Action to Control Cardiovascular Risk in Diabetes Blood Pressure (ACCORD-BP) study did not find a significant beneficial effect of intensive systolic blood pressure (SBP) lowering on cardiovascular events in hypertensive patients with type 2 diabetes mellitus (T2DM), while the Systolic Blood Pressure Intervention Trial (SPRINT) did find a significant beneficial effect in patients without T2DM. The objective of this analysis was to assess the effect of both T2DM and baseline cardiovascular disease risk on the treatment effect of intensive blood pressure lowering.

RESEARCH DESIGN AND METHODS

The individual patient data from the ACCORD-BP and SPRINT studies were pooled and follow-up durations harmonized. Both studies randomized hypertensive patients to an SBP target of <120 mmHg or a target of <140 mmHg. The composite primary end point consisted of unstable angina, myocardial infarction, acute heart failure, stroke, and cardiovascular death. The interaction between intensive blood pressure lowering and both T2DM and 10-year cardiovascular risk was assessed using Cox proportional hazards models.

RESULTS

The cohort consisted of 14,094 patients with mean age 66 ± 8.9 years and mean baseline SBP 139.5 ± 15.6 mmHg; 33.6% had T2DM. The hazard ratio for the primary composite end point was 0.82 (95% CI 0.73–0.93), P = 0.0017. The interaction between intensive blood pressure lowering and T2DM was nonsignificant (P = 0.13). The 10-year cardiovascular risk was higher in primary prevention patients with T2DM, but risk did not interact with the treatment effect (P = 0.84).

CONCLUSIONS

Intensive blood pressure lowering may have a similar favorable effect and appears to decrease cardiovascular events in both patients with and patients without T2DM.
Adaptive Diversification (MPB-48)
Authors: Doebeli Michael
Published: December 2017

Understanding the mechanisms driving biological diversity remains a central problem in ecology and evolutionary biology. Traditional explanations assume that differences in selection pressures lead to different adaptations in geographically separated locations. This book takes a different approach and explores adaptive diversification—diversification rooted in ecological interactions and frequency-dependent selection. In any ecosystem, birth and death rates of individuals are affected by interactions with other individuals. What is an advantageous phenotype therefore depends on the phenotype of other individuals, and it may often be best to be ecologically different from the majority phenotype. Such rare-type advantage is a hallmark of frequency-dependent selection and opens the scope for processes of diversification that require ecological contact rather than geographical isolation. This book investigates adaptive diversification using the mathematical framework of adaptive dynamics. Evolutionary branching is a paradigmatic feature of adaptive dynamics that serves as a basic metaphor for adaptive diversification, and the book explores the scope of evolutionary branching in many different ecological scenarios, including models of coevolution, cooperation, and cultural evolution. It also uses alternative modeling approaches. Stochastic, individual-based models are particularly useful for studying adaptive speciation in sexual populations, and partial differential equation models confirm the pervasiveness of adaptive diversification. Showing that frequency-dependent interactions are an important driver of biological diversity, the book provides a comprehensive theoretical treatment of adaptive diversification.

Published: December 2017

Objectives: The fast-rising rate of diabetes incidents is a growing concern in Central Asian countries. This article reviews the current understanding of type 2 diabetes etiology, progression and treatment options along with opportunities for utilizing Avicenna’s legacy in developing novel botanical therapeutics. Methods: Analysis of relevant publications, including a variety of Avicenna’s work in Arabic, English and Russian. Results: With conventional treatment strategy shifting from single-component drugs aimed at one target to multitherapeutic combinations addressing the complex nature of many diseases and conditions, the role of multicomponent botanical preparations may increase. Diabetes mellitus is a serious chronic, progressive disease characterized by hyperglycemia, which is associated with a variety of comorbidities because of considerable damage, dysfunction and failure of multiple organs developed through the disease’s progression. Multidisciplinary collaborative research that encompasses innovative tools could be used for effective development of new comprehensive therapeutic products and treatments based on knowledge of traditional medicine and supported by contemporary scientific validation. Conclusion: Comprehensive analysis of Avicenna’s 1,000-year-old approach to the treatment of prediabetes and diabetes provides valuable directions in the search for plant-based treatments. Botanical therapeutics may provide relatively inexpensive and safe methods for diabetes treatment.
Colombia ciencia sin futuro

Colombia no será nada hasta que no se eduque su gente, es un país que está retrasado intelectualmente; un país que no valora la ciencia es porque nadie les ha enseñado a sus ciudadanos su valor y sus dirigentes no lo entienden, es porque no les interesa, según lo comentó GINAS, (2004). “El futuro de Colombia va a estar profunda y directamente relacionado con la capacidad que los colombianos tengamos de organizar la educación; la hija de la educación: la ciencia; y la hija de la ciencia: la tecnología-GINAS, 1993” (CORREA, 2017), hoy la ciencia en Colombia no tiene futuro; la inversión pública para ciencia disminuirá para el año 2018 en 41.5 %. El punto de inversión más alto fue de $430.150 millones para el año 2013; para 2014 bajó a $376.768 millones, en 2015 pasó a $332.197 y en 2016 perdió otra porción y se redujo a $304.516 millones. Este año bajó hasta $299.177 millones y para el 2018 se prevé será el más bajo en una década, con apenas $220.506 millones (CORREA, 2017). Las mayores repercusiones se reflejarán en el congelamiento de nuevas becas para programas doctorados y en el presupuesto para convocatorias de proyectos de investigación (EL ESPECTADOR, 2017).

Partisipasi Masyarakat Lokal Medan: Sebuah Tinjauan Atas Kriteria Nasional Pada Proses Penetapan Sebagai Cagar Budaya
Authors: Fitri Isnen
Published: December 2017

Among the important problems encountered in the implementation of cultural heritage preservation in Indonesia nowadays is the establishment of the cultural register in national, province, or regency/city levels. Criteria in article 5 of the Law on Items of Cultural Heritage No.11/2010 are insufficient for the process of assigning historical assets as cultural heritage items. The criteria also seem to merely be a “copy and paste” of the previous law. Meanwhile, at the global level, during the last several decades, many countries have begun to adopt the concept of the important values of heritages, which is depicted in the Burra Charter as a reference to develop criteria in assigning items of cultural heritages. To improve our national criteria in the near future, this study is aimed at evaluating national criteria in article 5 based on opinions of 33 representatives of local communities in Medan, as stakeholders in the preservation of cultural heritages in the city of Medan, by performing interviews and group discussions using Nominal Group Technique or NGT. From the diverse opinions of the 33 participants obtained from the two phases of data collecting process, it is concluded that our national criteria in assigning an item of cultural heritage that were mentioned in article 5 of the Law on Items of Cultural Heritage No.11/2010 are still obscure, difficult to measure, overlapping, and not quite in line with global trend. Most participants disagree that age is used as the main criteria. There are a number of suggestions (inputs) from the participants to improve the sentences in article 5 to form criteria that are easier to measure and independent.

Problem based learning supports students to have an ability to solve problems in real life, so that students’ critical thinking skill is structurally able to appear and is examined well. By problem based learning, students are able construct their own knowledges. This research is held in elementary school using true experimental with test post-test control group design. It uses quantitative descriptive approach. The data of critical thinking skill indicates that problem based learning does not affect significantly toward students’ critical thinking. The data of learning outcomes is analyzed by using t-test in 5 % signification level. The calculation result using t-test gains tcount = 2, 533. This value is consulted to ttable with db = 54 in 5 % signification level, so that it gains ttable = 2,005. It gains tcount>ttable (2,533 > 2,005). Based on its result, it can be concluded that problem based learning affects students’ learning result, unlike students’ critical thinking skill.

Published: December 2017

The MT-ATP6 gene encodes for a protein subunit which is central to the proton channel of the ATP synthase. Mutations of MT-ATP6 gene can affect the ATP synthesis and may play an important role in the process of tumorigenesis. The purpose of this study was to identify potential changes of MT-ATP6 gene in pair of tumor and adjacent tissues of 102 patients with breast cancer and in blood samples of 65 controls by using direct DNA sequencing and PCR-RFLP method. Then, statistical analysis was used to analyze the association between some typical changes and pathological features of breast cancer. As a result, 20 changes in the MT-ATP6 gene in 35 examined breast cancer tissues and 13 changes in 26 blood control samples were reported, of which 12 alterations altered the amino acid and a variant, 9183insC, had not been described in the literature so far. Most of the variants had low frequencies from 2.86% to 5.71%. Two variants, G9053A and G8584A, which changed the amino acid sequence and had high frequency, were screened in all samples. Our results indicated that the frequencies of G9053A and G8584A were 21,6% (22/102 cases) and 24,5% (25/102 cases) respectively in tissues of breast cancer patients and 18,5% (12/65 cases) in normal blood controls. However, there was no statistically significant difference in G9053A and G8485A rates between breast cancer patients and controls as well as between mtDNA alterations and the pathological features of breast cancer such as age, size of tumors, number of lymph nodes, size of lymph nodes, T stage, N stage, tumor differentiation and stages of disease. This study showed that the variations of MT-ATP6 gene differed from patient groups. In Vietnamese patients with breast cancer, the rates of G9053A and G8485A were relatively high but these changes were not statistically related to breast cancer.

Проаналізовані результати мініінвазивних ендоскопічних втручань у 31 хворого з приводу портальної біліопатії (ПБ). У 7 (23%) хворих ПБ виникла на тлі тромбозу ворітної вени (ВВ), у 19 (61%) - виявлені клінічні ознаки, пов’язані з ураженням жовчних проток: холедохолітіазу (у 16%), стриктури (у 35%), папілостенозу, що супроводжувалося гіпербілірубінемією, жовтяницею, холангітом. Діагностичний комплекс включав ультразвукове дослідження (УЗД) з допплерографією, контрастно-підсилену комп’ютерну томографію (КТ), магніторезонансну холангіопанкреатикографію (МРХПГ), діагностичну та лікувальну ендоскопічну ретроградну холангіографію (ЕРХГ) з папілосфінктеротомією (ЕПСТ), літоекстракцією, ендобіліарним стентуванням. Ендоскопічні транспапілярні втручання, не усуваючи основну патогенетичну причину ПБ - портальну гіпертензію (ПГ), дозволяють у більшості хворих вирішити проблеми біліарної гіпертензії.
Nature Conservation Against All? Aquatic Macrophyte De-Weeding – Cut or Conserve? A Stakeholder Analysis
Authors: Brummer Vasco , Roth Sandra , Röhl Markus , Herbes Carsten
Published: December 2017

De-weeding of streams and lakes occurs in Germany on a widespread level, mostly to ensure water runoff and to provide flood protection. But de-weeding also affects a range of stakeholders, who have their own reasons to support or oppose it. For the list of stakeholders identified, see chapter 4. As part of a project analysing the feasibility of using water plant biomass as a substrate for biogas production, we conducted a multi-method stakeholder analysis to evaluate stakeholders’ opinions about de-weeding. The results show a preference of all stakeholders, except those identifying with nature conservation, for aquatic de-weeding. Our findings also point to a lack of communication between stakeholders, resulting in biased opinions of the stakeholders against other stakeholders and starting points for conflict.

Published: December 2017

The rising price of higher education and its implications for equity and accessibility have been extensively documented, but the material conditions of students’ lives are often overlooked. Data from more than 30,000 two- and 4-year college students indicate that approximately half are food insecure, and recent estimates suggest that at least 20% of 2-year college students have very low levels of food security. At least one-third of 2-year students are housing insecure, including up to 14% who are homeless, whereas between 11% and 19% of 4-year students are housing insecure. Most of these students work and receive financial aid, but only a fraction receive public or private assistance to help make ends meet. Implications for research on college affordability and efforts to boost college graduation rates are discussed.
Mercury Removal From Produced Water Using Subcritical Water Assisted 1-Etyl-3- Methylimidazolium Chloride Ionic Liquid
Authors: Mandal Pradip Chandra , Bin Esa Ahmad Fahmi Ridhuan
Published: December 2017

Production of produced water from oil and gas industries are increasing day by day for enhancement of oil recovery. Insoluble mercury such as mercury sulfide and oxide, and dissolved mercury such as organomercury, ionic mercury and elementary mercury are present in produced water along with the other impurities. Mercury is not only hazardous to human health and the environment but could also attack process equipment components that have mercury reactive materials, leading to potential catastrophic failure to the plant. So, removing mercury from produced water is now a pressing issue for the environmental point of view. A lot of mercury separation techniques such as adsorption, precipitation etc. have been developed all over the world. But the traditional mercury removal processes are not suitable to remove mercury from produced water. The aim of this paper is to remove mercury from produced water using subcritical water assisted ionic liquid (IL) for the first time. In this study, 1-etyl-3- methylimidazolium chloride, [EMIM][Cl], IL was utilized. The potential experiments were conducted in a batch type extractor at temperatures of 130 - 180ºC, a pressure of 0.2 MPa and treatment times of 0 - 10 min. The concentration of mercury(II)ions in ILs were analyzed using UV-VIS spectrophotometer and IL was analyzed using FT-IR to study the structure of ILs. The results show that [EMIM][Cl] IL has the ability to absorb mercury from produced water and almost 99.5% mercury was removed at a temperature of 180oC, a pressure of 0.2 MPa and a treatment time of 10 min by the action subcritical water assisted [EMIM][Cl]. In addition, mercury removal follows first order kinetics with an activation energy of 2.52 kcal per mol and a pre-exponential factor of 1.093 s-1. Therefore, the subcritical water assisted ILs can be used to remove mercury from produced water of oil and gas industries.Journal of Chemical Engineering, Vol. 30, No. 1, 2017: 12-15

Published: December 2017

Fire accident in a shopping mall, garments factory and other labor intensive industries nowadays has become a common incident in Bangladesh and poses a great threat to life, facilities and economy of our country. In this work, fire and evacuation simulation was performed for a single stored shopping complex utilizing computational fluid dynamic techniques. Fire Dynamic Simulator with evacuation (FDS+Evac) software was used to simulate a shopping mall fire and study the effects of fire on the emergency egress process of people. The shopping mall of area 64 m2 comprises of seven rooms with a pool fire at the center of the mall is modeled for simulation. The total evacuation time (TET) for a fixed population density were estimated with the change of heat release rate, soot yield, soot density and the design pattern or geometry of shopping mall. The evacuation of agents in different time and different design pattern of the mall has been assessed using the data obtained from the simulation. FDS+Evac provides an integrating platform where the interaction between fire growth and evacuees can be taken into account by simultaneous simulation allowing a full coupling of the fire conditions and human behavior. This makes FDS is an effective tool for simulating large and high density crowds where the movement dynamics of evacuees is affected by the crowd pressure. Full scale fire experiment is often quite difficult to study the fine and crowds evacuation behavior. This paper illustrates a promising application of fire dynamic simulator (FDS+Evac) for fire and evacuation modeling to predict the total evacuation time.Journal of Chemical Engineering, Vol. 30, No. 1, 2017: 32-36

Published: December 2017

Background: Beta-Thalassaemia Trait (β-TT) is common in this subcontinent as well as Bangladesh. 3% of our total population is documented to have β-TT. Iron deficiency anemia (IDA), remains one of the most severe and important nutritional disorder in the world especially in Bangladesh. Microcytic hypochromic blood picture is common manifestation of both disorders. Purpose of the present study was to see whether both can co-exist.Methods: This was a cross sectional study carried out in Department of Internal Medicine, Bangabandu Sheikh Mujib Medical University (BSMMU), Dhaka from January-2014 to August-2015. Total 54 participants were selected from Haematology outpatient department (OPD), BSMMU. All of them had β-TT confirmed by Capillary Haemoglobin Electrophoresis. Proper counseling was done and informed consent was taken. Relevant history was taken and examination was done. Five ml of venous blood was collected and sent to Biochemistry department to measure serum iron, ferritin and tissue iron binding capacity (TIBC). Transferrin saturation (T.Sat) was calculated by formula (iron/TIBC) X100.Results: Total 54 patients who fulfilled the recruitment criteria were finally analyzed. Among them 85% (46) patients were females and 15% (8) were males. Median age was 30 years (range11-80 yrs). Most of the patients 78 % (42) belong to the age group between 15 to 44 years. Mean (±SD) HbA2 (%) was 5.35 (±1.39), Hb (%) 9.04± (1.39), MCV (fl)- 67.02 (±10.39), MCH (pg)- 21.06 (±3.99), RDW (%)- 17.77 (±3.85). Among them 44.4% (24) had low iron (<40μg/dl), 29.6 % (16) had low ferritin (15μgm/L), 33.3% (18) had high TIBC (>407μg/dl), and 50% (27) had low transferrin saturation (<16%). 13% (7) patients were found to be iron deficiency considering all parameters and 63% (34) patients were iron deficient in at least one parameter.Conclusions: The present study shows the frequent occurrence of iron deficiency (29.6%) in subjects with β-TT which is a potentially correctable clinical condition. Proper assessment of iron level among the β-TT should be done and those who are iron deficient, should be treated promptly which may improve their general wellbeing.J MEDICINE Jan 2018; 19 (1) : 44-48

Mitochondrial disease, once thought to be a rare clinical entity, is now recognized as an important cause of a wide range of neurologic, muscle, cardiac and endocrine disorders. Kearns Sayre syndrome is a rare mitochondrial disease, involving deletion of mitochondrial DNA. This syndrome ischaracterized by progressive external ophthalmoplegia (PEO), retinitis pigmentosa and an onset before the age of 20 years. First case was reported in 1958. We are reporting a case with chronic progressive external ophthalmoplegia, bilateral partial ptosis with onset at 10 years of age. He also had features of myopathy and neuropathy without any fatigable weakness. Our diagnosis is mostly based on clinical background and by exclusion of other common disorders, as definitive diagnostic investigation genetic testing due to unavailability so was not done.J MEDICINE Jan 2018; 19 (1) : 66-69
