Background and purpose: Bacterial and fungal bioaerosols play important roles in the atmosphere and have significant effects on human health. This study aimed at investigating the concentration of bioaerosols in ambient air in Shahrekord, Iran during two warm and cold seasons at three different points in 2019. Moreover, the effect of meteorological factors such as temperature, relative humidit...
This chapter presents the use of the additive manufacturing (AM) method powderbinder-jetting (PBJ) for the generation of molds and cores for casting applications. Theoretical information on process steps and the binding of particles is given. For the based chemistry, examples are presented and the transfer from conventional produc‐ tion processes to powder-binder-jetting is explained. For sand ...
In a nursery pollination mutualism, we asked whether environmental factors affected reproduction of mutualistic pollinators, non-mutualistic parasites and seed production via seasonal changes in plant traits such as inflorescence size and within-tree reproductive phenology. We examined seasonal variation in reproduction in Ficus racemosa community members that utilise enclosed inflorescences ca...
Ventilation/perfusion (V/Q) lung scintigraphy, when used for the clinical determination of the presence or absence of pulmonary embolism, has been much studied by medical imagers. Inherent to a ‘‘cold-spot’’ scan targeting the normal pulmonary tissue, the deck has always been stacked against us and our specialty frequently maligned by the referring physicians as practicing ‘‘unclear’’ and not n...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
AIM To identify the suitable roofing pattern for dairy cattle in North East Zone of Tamil Nadu, India, based on micro climatic conditions. MATERIALS AND METHODS Initially, survey was conducted to identify and categorize the major housing patterns existing in the region for further detailed investigation. In total, 30 farmers/farms consisting of five housing types with six replicates were sele...
Introduction: Continuous exposure to cold air is considered to be a hazardous agent in the workplace in cold seasons. This study aimed to determine the level of cold stress and relation with physiological responses in auto mechanic employees. Method: This cross-sectional study was conducted in the winter of 1395 on auto mechanic employees in Hamadan city. Physiological responses during daily...
Background and purpose: Petrochemical industries and refineries are regarded as important emission sources of inorganic and organic pollutants. The aim of this study was to survey TVOCs and BTEX in the air of South Pars Special Economic Energy Zone in 2014. Materials and methods: In a cross-sectional study sampling and analysis was done by NIOSH 1501 method. The study was carried out in 336 ...
The diet and prey selection of the Southern Grey Shrike (Lanius meridionalis koenigi) was studied in one of the scarce insular environments where it is present, the xeric coastal area of Tenerife (Canary Islands). The main aim of this study was to compare the general trophic patterns with respect to continental populations of Northern Grey Shrike (Lanius excubitor) and Southern Grey Shrike. The...
Population monitoring is vital for conservation and management. However, simple counts of animals can be misleading and this problem is exacerbated in seals (pinnipeds) where individuals spend much time foraging away from colonies. We analyzed a 13-year-series of census data of Galapagos sea lions (Zalophus wollebaeki) from the colony of Caamaño, an islet in the center of the Galapagos archipel...
