This paper presents the influence of Hybrane H 1500 as a hyperbranched polymer on kinetic parameters of dyeing compounded fiber grade PET polyethylene terephthalate at boil temperature. C.I. Disperse Red 324 as a disperse dye was used for dyeing compounded fiber grade PET. The result was compared with corresponding properties of virgin PET. The dyeing rate constants and diffusion coefficients a...

avian chlamydiosis is one of the most important infectious diseases of birds. despite the rapid growth of exotic bird populations in iran, there is little or no information on the specific infections that these types of birds carry. in this study, conventional isolation methods were used in cell culture to study occurrence of infection in pet birds. samples from the conjunctiva, choana, and clo...

city parks play an important role in the welfare of metropolitan people. higher species richness of birds can be considered as a reflection of the health of the park and may satisfy visitors to a higher extent being in a more natural environment. we studied the influence of area and shape of city parks on bird species richness and diversity. 13 parks from among the 35 main city parks in isfahan...

Bird strikes present a huge risk for aircraft, especially since traditional airport bird surveillance is mainly dependent on inefficient human observation. Computer vision based technology has been proposed to automatically detect birds, determine bird flying trajectories, and predict aircraft takeoff delays. However, the characteristics of bird flight using imagery and the performance of exist...

Hoyer, M. V.,j. Winn and D. E. Canfield,Jr. 2001. Citizenmonitoring ofaquatic bird populations using a Floridalake. Lake and Reserv. Manage. 17(2):82-89. Five years of monthly bird counts on a 2.32 km2 lake in north central Florida were used to examine the ability of a citizen volunteer to monitor aquatic bird populations. When compared to published aquatic bird data, collected by professional ...

Avian Influenza (AI) H9N2 is endemic in Iran; therefore, it is necessary to estimate the disease prevalence among birds in live bird markets (LBMs) and assess the risk spread across the country. Accordingly, this study aimed to estimate the prevalence of AI subtypes in LBMs, bird gardens, and zoos during October and November 2015 in Iran and investigate the associated risk factors. Data related...

Background: Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are tightly associated inflammatory conditions of the elderly [1]. Both disorders can exhibit an increased articular vascular uptake 18-fluorodeoxyglucose (18-FDG) at positron emission tomography (PET)/computed (CT) scan [2]. Objectives: This study evaluated if large-vessel vasculitis (LVV) detected by PET/CT in patients wi...

in this paper, we review novel techniques in the emerging field of spatiotemporal 4d pet imaging. we will discuss existing limitations in conventional dynamic pet imaging which involves independent reconstruction of dynamic pet datasets. various approaches that seek to attempt some or all of these limitations are reviewed in this work, including techniques that utilize iterative temporal smooth...

Urban development is rapidly expanding across the globe and is a major driver of environmental change. It is important to understand how bird species responds to urbanization. Therefore I conducted a qualitative study of birds associated with waste sites such as dumpsite and sewage stabilization ponds was carried out on Moshi municipal. The study assessed the diversity between dumpsite and sewa...
