  • Connecting Bangladesh: Economic Corridor Network
    Connecting Bangladesh: Economic Corridor Network Economic corridors are anchored on transport corridors, and international experience suggests that the higher the level of connectivity within and across countries, the higher the level of economic growth. In this paper, a new set of corridors is being proposed for Bangladesh—a nine-corridor comprehensive integrated multimodal economic corridor network resembling the London Tube map. This paper presents the initial results of the research undertaken as an early step of that development effort. It recommends an integrated approach to developing economic corridors in Bangladesh that would provide a strong economic foundation for the construction of world-class infrastructure that, in turn, could support the growth of local enterprises and attract foreign investment. About the Asian Development Bank COnnecTING BANGLADESH: ADB’s vision is an Asia and Pacific region free of poverty. Its mission is to help its developing member countries reduce poverty and improve the quality of life of their people. Despite the region’s many successes, it remains home to a large share of the world’s poor. ADB is committed to reducing poverty through inclusive economic growth, environmentally sustainable growth, and regional integration. ECONOMIC CORRIDOR Based in Manila, ADB is owned by 67 members, including 48 from the region.

  • The Completeness and Vulnerability of Road Network in Bangladesh
    M. A. Ali, S. M. Seraj and S. Ahmad (eds): ISBN 984-823-002-5 The Completeness and Vulnerability of Road Network in Bangladesh A. S. M. Abdul Quium and S. A. M. Aminul Hoque Department of Urban and Regional Planning Bangladesh University of Engineering and Technology, Dhaka-1000, Bangladesh Abstract Road transportation has emerged as the most popular mode of transportation in Bangladesh. Despite being the most popular mode, it suffers heavily from network failures due to natural as well as man-made disruptions. This paper presents the major findings of a study relating to the completeness of the road network with respect to the pattern of traffic flow and its vulnerability with reference to the disruptions caused by the flood of 1998. The study considered development of road network by regions on the basis of degree of network completeness by connectivity indices namely, γ and α indices that apply the Graph Theory to measure the geometric pattern of a network. The analysis revealed that the road network development in Bangladesh at the national and regional levels is still in its early stage. The existing network has a very few circuits for movement at all the levels and, therefore, susceptible to high risk of disruption. In terms of circuitry, the network has a bare marginal grid configuration at the divisional and national levels. The present overwhelming dependence on road transportation system will continue in the future. In this context, completeness of the whole road network should be considered in all future road planning exercises. Assessment of vulnerability of links around Dhaka deserves special consideration as any link failure of the national highways around Dhaka affects almost the whole system.

Schroeder Follow this and additional works at: https://mds.marshall.edu/mathematics_faculty Part of the Discrete Mathematics and Combinatorics Commons AUSTRALASIAN JOURNAL OF COMBINATORICS Volume 74(1) (2019), Pages 46–60 On the existence of partitioned incomplete Latin squares with five parts Jaromy Kuhl Donald McGinn Department of Mathematics and Statistics University of West Florida Pensacola, FL 32514 U.S.A. [email protected] [email protected] Michael William Schroeder Department of Mathematics Marshall University Huntington, WV 25755 U.S.A. [email protected] Abstract Let a, b, c, d,ande be positive integers. In 1982 Heinrich showed the existence of a partitioned incomplete Latin square (PILS) of type (a, b, c) and (a, b, c, d) if and only if a = b = c and 2a ≥ d. For PILS of type (a, b, c, d, e) with a ≤ b ≤ c ≤ d ≤ e, it is necessary that a + b + c ≥ e, but not sufficient. In this paper we prove an additional necessary condition and classify the existence of PILS of type (a, b, c, d, a + b + c)andPILS with three equal parts. Lastly, we show the existence of a family of PILS in which the parts are nearly the same size. 1 Introduction Let a, n ∈ Z+ and S be a symbol set of order n.Let[n]={1,...,n}, a+S = {a+s | s ∈ S},andaS be the multiset in which each element of S occurs a times.

  • Tuberculosis Infectious Pool and Associated Factors in East Gojjam Zone, Northwest Ethiopia Mulusew Andualem Asemahagn1* , Getu Degu Alene1 and Solomon Abebe Yimer2,3
    Asemahagn et al. BMC Pulmonary Medicine (2019) 19:229 https://doi.org/10.1186/s12890-019-0995-3 RESEARCH ARTICLE Open Access Tuberculosis infectious pool and associated factors in East Gojjam Zone, Northwest Ethiopia Mulusew Andualem Asemahagn1* , Getu Degu Alene1 and Solomon Abebe Yimer2,3 Abstract Background: Globally, tuberculosis (TB) lasts a major public health concern. Using feasible strategies to estimate TB infectious periods is crucial. The aim of this study was to determine the magnitude of TB infectious period and associated factors in East Gojjam zone. Methods: An institution-based prospective study was conducted among 348 pulmonary TB (PTB) cases between December 2017 and December 2018. TB cases were recruited from all health facilities located in Hulet Eju Enesie, Enebse Sarmider, Debay Tilatgen, Dejen, Debre-Markos town administration, and Machakel districts. Data were collected through an exit interview using a structured questionnaire and analyzed by IBM SPSS version25. The TB infectious period of each patient category was determined using the TB management time and sputum smear conversion time. The sum of the infectious period of each patient category gave the infectious pool of the study area. A multivariable logistic regression analysis was used to identify factors associated with the magnitude of TB infectious period. Results: Of the total participated PTB cases, 209(60%) were male, 226(65%) aged < 30 years, 205(59%) were from the rural settings, and 77 (22%) had comorbidities. The magnitude of the TB infectious pool in the study area was 78,031 infectious person-days. The undiagnosed TB cases (44,895 days), smear-positive (14,625 days) and smear- negative (12,995 days) were major contributors to the infectious pool.

  • Antigenic and Genetic Characteristics of Zoonotic Influenza Viruses and Development of Candidate Vaccine Viruses for Pandemic Preparedness
    4 Antigenic and genetic characteristics of zoonotic influenza viruses and development of candidate vaccine viruses for pandemic preparedness February 2019 The development of influenza candidate vaccine viruses (CVVs), coordinated by WHO, remains an essential component of the overall global strategy for pandemic preparedness. Selection and development of CVVs are the first steps towards timely vaccine production and do not imply a recommendation for initiating manufacture. National authorities may consider the use of one or more of these CVVs for pilot lot vaccine production, clinical trials and other pandemic preparedness purposes based on their assessment of public health risk and need. Zoonotic influenza viruses continue to be identified and evolve both genetically and antigenically, leading to the need for additional CVVs for pandemic preparedness purposes. Changes in the genetic and antigenic characteristics of these viruses relative to existing CVVs, and their potential risks to public health justify the need to select and develop new CVVs. This document summarizes the genetic and antigenic characteristics of recent zoonotic influenza viruses and related viruses circulating in animals1 that are relevant to CVV updates. Institutions interested in receiving these CVVs should contact WHO at [email protected] or the institutions listed in announcements published on the WHO website2. Influenza A(H5) Since their emergence in 1997, highly pathogenic avian influenza (HPAI) A(H5) viruses of the A/goose/Guangdong/1/96 haemagglutinin (HA) lineage have become enzootic in some countries, have infected wild birds and continue to cause outbreaks in poultry and sporadic human infections. These viruses have diversified genetically and antigenically, including the emergence of viruses with replacement of the N1 gene segment by N2, N3, N5, N6, N8 or N9 gene segments, leading to the need for multiple CVVs.
