The Impact Of Social Partnership On The Environment
Authors: Ep Chedli Mariem Kchaich
Published: August 2017

The multidimensional social problems that everyone seeks to remedy them are very complex and no actor can confront them on their own. So the different parties have to work together by creating relations of partnerships.The State has long been the main actor in the control and regulation of social relations. However, in recent years there has been a rapid decline in their role given the enormous charge and lack of resources. Hence the need for the intervention of other parties.Some review of literature explores the conceptualization of social partnership in order to meet the needs of the organization or solve organizational problems. More and more large companies and multinationals get started on a voluntary approach to social responsibility and have begun to move closer to certain social enterprises by concluding partnership agreements.The purpose of this study was to study the social transformation that follows the creation of a relation of a social partnership between a social enterprise and a company that has involved a strategy of social responsibility. Then, we will present the environment to finally study the impact of social partnership on the environment; on economic, cultural and political dimensions.

BANKING SYSTEMS IN ROMANIA AND ICELAND: TWO DIFFERENT WORLDS BUT SIMILAR DEVELOPMENT
Authors: Baicu Claudia Gabriela , Mixa Mar Wolfgang
Published: August 2017

The novelty of this paper is the comparative analysis of the Romanian and Icelandic banking systems. The study results reveal that despite the fact that Romania and Iceland are two different worlds, there are several similarities between the banking systems of these countries. They include a late development of banking systems, foreigners contributing a great deal to the development of the banking systems in the early stage of evolution. After the Second World War until the 1990s specialized banks operated in both countries. The banking systems of both countries prior to the 1990s were dominated by politics. Liberalization of banking and capital occurred both in Romania and Iceland after 1990; the bank privatization process took place during a similar period (1999-2006, Romania; 1998-2002, Iceland). Before privatization, banks in both countries lacked experience in a new banking “arena”. The global financial crisis greatly affected the two banking systems. Despite similarities, the evolution of the two banking systems was also marked by differences, notably the ownership origin of banks after privatization (foreign dominance in Romania; domestic owners in Iceland) and different business models developed by banks in the pre-crisis period.

Trustee contracts referring to the special provisions on guarantees stipulated by Bapepam (Capital Market Supervisory Agency)/OJK (Financial Service Authority) as referred in item 4 letter E Kep. Bapepam-LK No.412 / BL / 2010 are considered too general. The provision of guarantee on number 4 letter E Kep. Bapepam No.412 is limited to informational provisions, not a requirement. The purpose of this paper is to know and analyze the implementation of bond arrangements and weaknesses in the capital market of Indonesia based on the value of justice. Why there are weaknesses in the implementation of bond arrangement in Indonesia capital market. This research used sociological juridical method. The theories used to analyze were the theory of Degrading Justice as the Grand Theory, Theory of Legal Protection as the Middle Range Theory and Theory of the Covenant as Applied Theory. Based on the results of research implementation of bond arrangement in Indonesia capital market does not give justice value to the parties such as issuer, trustee and investor in particular. Unclear arrangements in Bapepam-LK's Decree on General Provisions and Trustee Contracts under the Warranty (if any) do not provide legal certainty and fairness to bond investors in the event of default. The weaknesses in the implementation of bonds arrangement in the Indonesian capital market due to the functions and duties of the Trustee listed in UUPM have no regulatory arrangements, as well as the absence of guidelines/standards in the preparation of the trustee contract. The reconstruction of the law shall be conducted by changing the special provisions of Bapepam Decree Number 412 on item 4 letter E concerning the guarantee (if any) by removing / removing the existing word in parentheses (if any), as it does not reflect the value of legal certainty and dignified justice.

Quantile Regression Analysis of Transit Travel Time Reliability with Automatic Vehicle Location and Farecard Data
Authors: Ma Zhenliang , Zhu Sicong , Koutsopoulos Haris N. , Ferreira Luis
Published: August 2017

Transit agencies increasingly deploy planning strategies to improve service reliability and real-time operational control to mitigate the effects of travel time variability. The design of such strategies can benefit from a better understanding of the underlying causes of travel time variability. Despite a significant body of research on the topic, findings remain influenced by the approach used to analyze the data. Most studies use linear regression to characterize the relationship between travel time reliability and covariates in the context of central tendency. However, in many planning applications, the actual distribution of travel time and how it is affected by various factors is of interest, not just the condition mean. This paper describes a quantile regression approach to analyzing the impacts of the underlying determinants on the distribution of travel times rather than its central tendency, using supply and demand data from automatic vehicle location and farecard systems collected in Brisbane, Australia. Case studies revealed that the quantile regression model provides more indicative information than does the conditional mean regression method. Moreover, most of the coefficients estimated from quantile regression are significantly different from the conditional mean–based regression model in terms of coefficient values, signs, and significance levels. The findings provide information related to the impacts of planning, operational, and environmental factors on speed and its variability. On the basis of this information, transit designers and planners can design targeted strategies to improve travel time reliability effectively and efficiently.
Estimation of Platform Waiting Time Distribution Considering Service Reliability Based on Smart Card Data and Performance Reports
Authors: Wahaballa Amr M. , Kurauchi Fumitaka , Yamamoto Toshiyuki , Schmöcker Jan-Dirk
Published: August 2017

The estimation of platform waiting time has so far received little attention. This research aimed to estimate platform waiting time distributions on the London Underground, considering travel time variability by using smart card data that were supplemented by performance reports. The on-train and ticket gate to platform walking times were assumed to be normally distributed and were matched with the trip time recorded by the smart cards to estimate the platform waiting time distribution. The stochastic frontier model was used, and its parameters were estimated by the maximum likelihood method. The cost frontier function was used to represent the relation between the travel time recorded in the smart card data as an output and the on-train time and walking time between the ticket gate and the platform as inputs. All estimated parameters were statistically significant, as shown by p-values. Comparing the travel time values estimated by the proposed model with the times recorded recorded in the smart card data shows a goodness-of-fit coefficient of determination of more than 95%. The estimation proved to have quick convergence and was computationally efficient. The results could facilitate improvements in transit service reliability analysis and passenger flow assignment. Matching the obtained distributions with the observed smart card data will help with estimating route choice behavior that can validate current transit assignment models.
Investigating Potential Transit Ridership by Fusing Smartcard and Global System for Mobile Communications Data
Authors: de Regt Karin , Cats Oded , Van Oort Niels , van Lint Hans
Published: August 2017

The public transport industry faces challenges in catering to the variety of mobility patterns and corresponding needs and preferences of passengers. Travel habit surveys provide information on overall travel demand as well as its spatial variation. However, that information often does not include information on temporal variations. By applying data fusion to smartcard and Global System for Mobile Communications (GSM) data, researchers were able to examine spatial and temporal patterns of public transport usage versus overall travel demand. The analysis was performed by contrasting different spatial and temporal levels of smartcard and GSM data. The methodology was applied to a case study in Rotterdam, Netherlands, to analyze whether the current service span is adequate. The results suggested that there is potential demand for extending public transport service on both ends. In the early mornings, right before transit operations are resumed, an hourly increase in visitor occupancy of 33% to 88% was observed in several zones, showing potential demand for additional public transport services. The proposed data fusion method was shown to be valuable in supporting tactical transit planning and decision making and can easily be applied to other origin-destination transport data.
Transit Trip Itinerary Inference with GTFS and Smartphone Data
Authors: Zahabi Seyed Amir H. , Ajzachi Ajang , Patterson Zachary
Published: August 2017

Many emerging technologies have been developed to supplement and contribute to conventional household travel surveys for transport-related data collection. A great deal of research has concentrated on the inference of information from global positioning system (GPS) data and data collected from mobile phones; methods for inferring transit itinerary have not received much attention. Automatic detection of transit itineraries from smartphone travel surveys could be used by planning agencies to predict transit demand and help in analysis of transit planning scenarios. This paper describes a proposed approach to infer transit itinerary smartphone travel survey and general transit feed specification data from Montreal, Quebec, Canada. Transit trips from the 2013 household travel survey were recreated and recorded with the DataMobile smartphone travel survey from May to July 2016. Transit itineraries were then validated—that is, collected data were associated with transit routes for all parts of the trips. The proposed transit itinerary inference algorithm was then applied to these validated data. The approach relied on the notion of transit route ambiguity—that is, because transit routes can overlap, any attempt to associate GPS data with routes when routes do overlap will result in ambiguity in identifying which routes were actually used. The proportion of transit trips with associated transit routes that were ambiguous was calculated under different assumptions, rules, and eventually a simple algorithm. Findings indicate that, by using this approach, 94.2% of transit trip distance can be assigned to either one transit route or walking, and thus there is reduced ambiguity. This resulted in 87% correct prediction of transit routes.
Modeling the Impact of Transit Fare Change on Passengers’ Accessibility
Authors: Ma Zhenyuan (Eric) , Masoud Abdul Rahman , Idris Ahmed O.
Published: August 2017

Accessibility “to” and “through” public transit has been one key transit planning indicator that reflects service quality. Occasionally, transit agencies may consider a fare change to maintain operations or to attract more passengers. However, transit agencies do not usually consider the effect of such fare change on passengers’ accessibility. This paper investigates that effect. A multinomial logit mode choice model is developed to measure the monetary value of transit users’ travel time. Then, the cumulative opportunity measure of accessibility is used to examine the change in job accessibility after a recent transit fare increase in the city of Kelowna, British Columbia, Canada. The results show that the loss in job accessibility resulting from transit fare increase is inversely proportional to the length of the trip, given a flat fare structure. The findings of this paper should be kept in mind before a transit agency rethinks transit fare structures. For example, a transit agency could consider applying a zone-based fare structure as opposed to a flat fare structure to ensure better equity for all transit users.
Perceived Reality

Published: August 2017

Ensuring that customers are satisfied with public transit is important, and traditionally transit agencies have assessed customer satisfaction by using questionnaires designed to collect information about users’ personal characteristics and perceptions of service. However, these questionnaires assess only individuals’ perceptions of transit services, without accounting for the service that users actually experienced. With that in mind, the purpose of this paper is to analyze the drivers of public transit satisfaction for users on the basis of an analysis of customer satisfaction questionnaires, as well as operations data obtained from automatic vehicle location and automatic passenger counter systems for an express bus route in Vancouver, British Columbia, Canada. The goal of the paper is to understand what the main factors influencing customer satisfaction in this context are. The paper questions whether using operations data in parallel with passengers’ perception data is useful in understanding customer satisfaction. With a series of logit models, it is found that actual crowding and users’ reported satisfaction with crowding are associated with how transit users perceive overall satisfaction with the bus service. Furthermore, the models reveal that car access, age, past use, and users’ perceptions of frequency, onboard safety, and cleanliness are also positively associated with overall satisfaction. This study could be useful for public transit planners as it provides new insight into how data derived from customer satisfaction surveys and bus operations can be used to identify which modifiable components of the service can be prioritized to effectively increase riders’ overall satisfaction.
Estimating Fare Noninteraction and Evasion with Disaggregate Fare Transaction Data
Authors: Sánchez-Martínez Gabriel E.
Published: August 2017

Public transportation authorities rely on electronic fare transaction records for revenue collection, service planning, and performance measurement. When passengers make public transportation trips without interacting with the fare system, demand is underreported and fare revenue is lost. In some cases, this issue is studied through costly manual surveys that cover a small portion of stops and times. Based on disaggregate fare transaction data, this research introduces a framework and stochastic model for estimating fare noninteraction and evasion on systems without automatic passenger counting. The model produces estimates by stop and time of day that could be used by agencies to effectively target fare inspection and off-board validation resources, as well as to improve the accuracy of scaling for inferred origin–destination matrices. Applying the model to morning peak trips originating at inbound surface stations of Boston’s Green Line, it is estimated that the authority loses $3,600 per weekday to fare evasion seen in about one-third of noninteractions and 9% of all trips. A card-specific parameter estimated by the model sheds light on personal attitudes toward noninteraction.
The Youth Pass
Authors: Thistle Ian , Paget-Seekins Laurel
Published: August 2017

Public transportation agencies provide reduced fares to seniors, students, and disabled people, but only infrequently provide discounts to low-income members of the general population. A major reason for this is that it is difficult and labor-intensive for transit agencies to determine who is of low income. To address societal need and pilot the feasibility of such a program, the Massachusetts Bay Transportation Authority (MBTA) piloted a program for young people who were unable to receive reduced fares in another way. The MBTA partnered with local municipalities, and applicants proved their eligibility for the program through partner offices. The research requirements in the program provided adequate data to evaluate the effects of the program, but the requirements themselves negatively affected participation and attrition in the pilot. The ways the research affected participation are explored in detail, particularly the attrition rate of subjects throughout the study. It was found that the research requirements disproportionately affected those of very low income as well as African-American and Hispanic participants. Using the data from the pilot, the MBTA decided to implement a full youth pass program benefiting those populations without the barriers of the pilot.
Exploratory Method for Practitioners Analyzing the Impact of Integrated Fare Structures in Decentralized Metropolitan Regions
Authors: Borjian Shahrzad , Schabas Jake , Segal John
Published: August 2017

Metrolinx, the regional transportation agency tasked with improving the coordination and integration of all transportation modes in the Greater Toronto and Hamilton Area, has developed an exploratory method for analyzing the effects of new fare structures that integrate the fare systems of multiple transit service providers in the region. The method uses a data set of all weekday trips made in the region segmented by modes used and origin–destination information. A formula derived from the mode choice modeling theory is used to obtain fare elasticity based on unit cost, mode share, and time of day. The distribution of elasticities produced is then calibrated according to a literature review of fare elasticities, and in the future, it will be done according to local market research. The result is a spreadsheet-based tool that provides analysts with an ability to test more complex changes to fare systems, including testing fare integration between agencies and introducing fares by distance, mode, time of day, or a combination of those features. Exploratory in nature, the method is not a replacement for comprehensive market research or fare pilots. However, it addresses the shortcomings of traditional fare analyses that use only aggregate elasticities for diverse market segments by better reflecting the spectrum of transit user sensitivities associated with specific travel characteristics. Furthermore, it provides analysts with a straightforward tool to test the effects of complex fare structures more commonly used in Europe and Asia enabled by smart card and open payment technology on ridership, revenue, emissions, and social equity.
Photo-Deposition of Ag Metal Particles on Ni-Doped TiO2 for Photocatalytic Application
Authors: Elahifard Mohammad Reza , Meidanshahi Reza Vatan
Published: August 2017

Ni-doped TiO2 and Ag-deposited@Ni-doped TiO2 photocatalysts were prepared using the co-precipitation technique and characterised using X-ray powder diffraction, scanning electron microscopy and Brunauer–Emmett-Teller analysis. Our results confirmed the presence of Ni atoms in the TiO2 bulk structure and Ag° metal particles deposited on the surface. The Ni impurity generates defect midgap states in the TiO2 band structure, providing visible light (VL) absorption, which are responsible for photocatalytic activity under VL conditions. Against this advantage, Ni changes the indirect band gap of pure anatase to the direct band gap which may dramatically suppress the photocatalytic activity of Ni-doped TiO2. Moreover, Ni may provide a centre of electron–hole (e–h) recombination which enhances the negative effect of Ni impurity on TiO2 photo-efficiency. These drawbacks were overcome by deposition of Ag° on the Ni-doped TiO2 which sinks the photo-excited electrons, quenching e–h recombination. This improvement yields three times more photo-efficiency in the decolourisation of Acid Blue 92. Although Ag@Ni-doped anatase shows a higher adsorption constant ( Kads) than Ag@Ni-doped rutile, both catalysts surprisingly present the same rate constant ( k).
A Review on Reactions of Polycyclic Aromatic Hydrocarbons with the Most Abundant Atmospheric Chemical Fragments: Theoretical and Experimental Data
Authors: Nayebzadeh Maryam , Vahedpour Morteza
Published: August 2017

Aerosols are ubiquitous in the atmosphere and have strong effects on climate and public health due to the importance of reactions of polycyclic aromatic hydrocarbon (PAH) compounds in air. Over the last decade, study of the reactions of PAHs and their derivatives in the atmosphere has become a key topic to find an effective way to decrease the impact of this spontaneous reaction and so reduce air pollution. This article aims to pool the majority of research on the reactions of PAHs with atmospheric agents such as oxygen, hydrogen and ozone and compare the theoretical and experimental results. In examining theoretical research, the number of aromatic rings is very important in calculating the rate constants and determining the main pathway of the reaction. So, while there are weak theoretical data, several papers issued in this field have concurred with key experimental results. For reactants with more than six aromatic rings, small basis sets have good conformity with experimental outcomes. Due to the abundance of OH in the atmosphere, much research has been done to find the best reaction pathway and calculate the associated rate constants experimentally and theoretically. In future, the opportunity exists for new researchers to detect the main intermediates, most important pathways, rate constants and the products of reactions with more than six aromatic rings and to detect PAHs in a dense atmosphere. Product identification will help to reduce air pollution.

Published: August 2017

A population of 50 chromosome‐specific cotton (Gossypium hirsutum L.) recombinant inbred lines (RILs), CS‐B17 RILs, was developed by inbreeding an F1 hybrid between ‘TM‐1’, the genetic standard line of upland cotton (G. hirsutum), and CS‐B17, a formally released interspecific chromosome substitution line. The parents, CS‐B17 and TM‐1, are genetically similar for all chromosome pairs except chromosome 17, which in CS‐B17 was replaced by chromosome 17 of 3‐79 (G. barbadense L.). Two CS‐B17 RILs, CS‐B17‐RIL‐59 (Reg. No. GP‐1021, PI 677340) and CS‐B17‐RIL‐98 (Reg. No. GP‐1022, PI 677342), were selected and released on the basis of their improved fiber quality traits, especially their favorable low micronaire values of 3.96 and 3.86, respectively, compared with the commercial lines ‘DP 393’ and ‘PHY 370 WR’, which had micronaire values of 4.52 and 4.58, respectively. However, the agronomic traits of the commercial lines were better than the released CS‐B17 RILs. Fiber with a micronaire value in the range of 3.7 to 4.2 is considered as the base range in the textile market, whereas US‐produced cotton averaged 4.40 over the past decade. These germplasm lines may provide genetic variation from G. barbadense that can be used to enhance cotton fiber quality of upland cotton.
A Study of Metro Organization Based on Multi-objective Programming and Hybrid Genetic Algorithm
Authors: Zhang Jun , Li Jiang , Wu Yan
Published: August 2017

Based on the train routing mode ascertained by suitability analysis, we construct a multi-objective problem to optimize the train routing, marshaling number and train headway from the perspective of general cost and segment load ratio by analyzing relevant characteristics like trip time, trip cost, operation cost, spatial distribution characteristics etc. Then the Singular Value Decomposition method and simulation software RailSys have been adopted to calibrate related parameters for the subsequent calculation. By comparison, the Genetic Algorithm is recommended to get an optimal solution to this multi-objective problem, and we improve the traditional algorithm by modifying the coding type, fitness function and crossover operation to enhance the efficiency and convergence. Finally, an operational mode which both satisfies the technological and passenger conditions has been identified to guarantee travellers’ safety, improve operation efficiency, save trip time and decrease cost.

Published: August 2017

Background: Dermtoglyphics are the lines and ridges forming a skin pattern, especially on the palm of the hands, fingertips and soles of feet. Differentiations of dermal ridges in early life are genetically determined1. Any disturbance by genetic factors causes development of unusual dermatoglyphics. On the other hand, deficiency of Mannose binding protein (MBP) gene and Interleukin-1 (IL-1) gene cause spread of pulmonary tuberculosis2. The dermatoglyphic pattern in patient with pulmonary tuberculosis can represent an anatomical, non-invasive, inexpensive tool for screening high-risk population, and facilitates early prediction of vulnerable population of PTB.Materials and Methods: A Cross-sectional, analytical type of study was conducted in Department of Anatomy, Dhaka Medical College, Dhaka, from January 2012 to December 2012. The study was performed in 100 patients suffering from pulmonary tuberculosis and 100 healthy individuals.Results: There was significant reduction in mean±SD of atd angle in pulmonary tuberculosis patients in comparison to control subjects. Mean±SD of atd angle was 37.87±3.403 in pulmonary tuberculosis patients and 49.77±4.628 in the control subjects. The difference was highly significant (P<0.001).Conclusion: The atd angle was found significantly narrower in the study group compared to the control subjects.Anwer Khan Modern Medical College Journal Vol. 8, No. 2: Jul 2017, P 85-88

Background: Hypotension during hemodialysis is common. In some patients, the development of hypotension necessitates intravenous fluid replacement before patients are able to safely leave the dialysis unit. Intradialytic hypotension may reduce the efficacy of the dialysis procedure and contributes to the excessive morbidity and mortality that is associated with hemodialysis.Aims: The aim of the study is to identify the patients who develops intradialytic hypotension and find out the aetiology, risk factors and outcome to reduce the mortality and morbidity of those patients.Methodology: This Cross sectional descriptive type of observational study was conducted in the Haemodialysis Unit of Anwer Khan Modern Medical College Hospital over the period from January 2015 to December 2016. The change in systolic pressure during haemodialysis was reviewed for ten consecutive haemodialysis in all the patients. The patients with chronic renal failure who were on regular dialysis were enrolled. Patients with sepsis, hemoglobin level less than 9 g/dL, low cardiac output, acute coronary syndrome, significant valvular lesion or body weight below the dry weight of the patient were excluded from the study.Result: Ninetythree patients were included in the study. Among them male 53(56.98%) and female 40(43.02%) with a M:F ratio was 1.3:1. The mean age of the patients was 53.50±16.82 (Range 13- 90).We found that 28%(26) of the patients developed intradialytic hypotension at least once in consecutive ten dialysis. Out of them 14 were female and 12 patients were male. All of the patients recovered from the incident after adequate management and stoppage of the ultrafiltrate volume, convert the machine to SLED(Sustained low efficacy dialysis) mode and hold antihypertensive drugs morning dose on the day of haemodialysis and treatment of the cause.Conclusion: As a result of increasing age of the patients receiving hemodialysis and the increasing incidence of diabetic nephropathy, hypotension will become a greater problem in future.Anwer Khan Modern Medical College Journal Vol. 8, No. 2: Jul 2017, P 89-93

Published: August 2017

Background: Infertility is a global health issue causing great personal sufferings and distress. It is also matter of social injustice and inequality. Both hyperthyroidism and hypothyroidism causes menstrual disturbances secondary to anovulation. The degree of disturbances varies from abnormal sexual development through menstrual irregularity to infertility.Objective: To assess thyroid hormone status in female infertility.Method: A cross-sectional study was carried out in the Department of Physiology, Dhaka Medical College, Dhaka during the period of July 2010 to June 2011. A total number of 250 female were included within the age limit of 20-40 years. Among them 125 subjects, healthy parous women were considered as control (group A) and 125 subjects, infertile women were considered as case (group B). The subjects were selected from Dhaka Medical College Hospital, infertility centre of BSMMU and BIRDEM, Dhaka. Data were collected in predesigned structured questionnaire form after taking consent. The study parameters are serumT3,T4 were measured in the Department of Nuclear Medicine, DMCH, Dhaka. For comparison between two groups, statistical analysis were done by Student's unpaired't' test. P<0.05 was considered as level of significance.Results: Serum T3 and T4 were significantly lower in group B than that of group A(P<0.001).Conclusion: From the results of the present study, it may be concluded that lower level of serum T3,T4 may be related with infertility.Anwer Khan Modern Medical College Journal Vol. 8, No. 2: Jul 2017, P 117-120

Background: Jaundice is the most common clinical condition in the newborn that requires medical attention. This study was carried out in order to assess the knowledge on neonatal jaundice management among the mothers in a selected tertiary level hospital of Dhaka city.Methodology: It was a descriptive type of cross-sectional study. 150 samples were selected by non randomized purposive sampling technique with the administration of a pretested, modified and semistructured questionnaire by face to face interview.Results: Study found that majority of the respondents (76.7%) was in the age group 17-27 years with mean age 23.78±5.397 years. Majority of the respondents (83.3%) had heard about neonatal jaundice previously and 16.7% did not hear about it. Regarding Knowledge on preventive measures of NNJ (neonatal jaundice) 90.6% respondents had knowledge on "Putting jaundiced baby under direct sun light", 62.7% said "Herbal remedies", 48% indicated "Consult with doctor" and 12% had knowledge on "phototherapy". Another major finding from the study was that 7.3% respondents had excellent level of knowledge regarding NNJ, whereas 40.0%, 34.0% and 18.7% had satisfactory, good and poor level of knowledge respectively. The Chi-square test model showed a significant association between previous knowledge of the respondents on NNJ with level of knowledge among the respondents (p= 0.027) and age of the respondents (p=0.012).Conclusion: Awareness should be created among the expecting mothers about neonatal jaundice and encourage them to take preventive measures to avert neonatal mortality and morbidity.Anwer Khan Modern Medical College Journal Vol. 8, No. 2: Jul 2017, P 121-127

Published: August 2017

Vitreous or retinal hemorrhage occurring in association with subarachnoid hemorrhage is known as Terson's syndrome. In Terson's syndrome, intracranial hemorrhages are followed by intraocular hemorrhage, classically in the subhyaloid space, but may also include subretinal, retinal, preretinal, and vitreal collections. Usually occurs in adult, but can be at any age. It may be unilateral or bilateral. Vitreous hemorrhage recovery is usually spontaneous within 6 to 12 months, otherwise vitrectomy is considered. We report a case of Terson's syndrome which was admitted in Anwer Khan Modern Medical College & Hospital as unilateral Terson's syndrome with multiple intra retinal hemorrhage of left eye associated with Hypertension & Diabetes Mellitus.Anwer Khan Modern Medical College Journal Vol. 8, No. 2: Jul 2017, P 153-156

Ovarian cancer is an alarming health problem in Bangladesh. The annual mortality rate per 100,000 people from ovarian cancer in Bangladesh has increased by 40.3% since 1990, an average of 1.8% a year. Globcan predicts a change in the reported incidence of ovarian cancer from 2912 in year 2012 to 3132 in 2015. Recurrent high-grade ovarian cancer is usually associated with short term survival. There are few guidelines to surgically and medically treat long term survivors with ovarian cancer. We are reporting three cases on advance ovarian cancer patients; all are married, age ranging from 40-60 years, primarily treated with chemotherapy. After that, they were experienced with FDA approved (Nov 14, 2014) monoclonal antibody Bevacizumab (AVASTIN), additionally with chemotherapy.Anwer Khan Modern Medical College Journal Vol. 8, No. 2: Jul 2017, P 157-161

In situ chemisorbed hydroxyl ion (OH-) onto clean polycrystalline gold (Au (poly)) electrode showed an extraordinary enhanced electrocatalytic activity towards oxidation of hydrogen peroxide anion (HO2-) in alkaline media. The oxidation of HO2- at the fabricated electrode was found to be a diffusion controlled process. The anodic transfer coefficient of the oxidation reaction was estimated as 0.47. Chloride ion (Cl-) replaced the chemisorbed OH- from the surface of the modified Au (poly) (OH-)Au (poly)) electrode leading to diminishing the observed electrocatalytic activity. The optimized concentration of KOH solution for the highest catalytic activity was found to be ca. 0.1 M. A linear calibration curve for various concentrations of HO2-? in the range of 0.5 to 5 mM was obtained having sensitivity equal to 1.028 A cm-2 M-1.Journal of Bangladesh Academy of Sciences, Vol. 41, No. 1, 29-36, 2017

Authors: Miah Saikh Shahjahan , Amin Md Ruhul
Published: August 2017

In this paper, we introduce two notions of T2 property in fuzzy topological spaces by using quasi-coincidence sense and we establish relationship among our and other such notions. We also show that all these notions satisfy good extension property. Also hereditary, productive and projective properties are satisfied by these notions. We observe that all these concepts are preserved under one-one, onto, fuzzy open and fuzzy continuous mappings. Finally, we discuss initial and final fuzzy topologies on our second notion.Journal of Bangladesh Academy of Sciences, Vol. 41, No. 1, 47-56, 2017
