A numerical and experimental investigation of flow and heat transfer in a gas- liquid Thermosyphon Heat Exchanger "THE" with built in heat pipes and aluminum plate fins for moderate Reynolds numbers has been carried out. It's module is composed of 6 rows and 15 columns copper pipes with aluminum plate fins with dimensions of 130cm height, 47cm width and  20cm depth. The tubes have been fill...

The majority of ectotherms grow slower but mature at a larger body size in colder environments. This phenomenon has puzzled biologists because classic theories of life-history evolution predict smaller sizes at maturity in environments that retard growth. During the last decade, intensive theoretical and empirical research has generated some plausible explanations based on nonadaptive or adapti...

Background: Recent trends have led many organizations to use a strategic planning for designing and implementing total quality management (TQM) as a fundamental necessity. This study aims to investigate the role of TQM in the quality maturity of hospitals from the employees’ point of view. Methods: A cross-sectional study was conducted among senior managers and officials of   three Zanjan Univ...

Banana ‘Cavendish’ and avocado are grouped into climacteric fruits perishable in nature after harvest. The facts that both harvested when they still green make difficulties detecting fruit maturities. This occurs because the harvest criteria carried out physically, where with same physical may have different levels of physiological maturity. Thermal image (TI) is a non-invasive, non-contact non...

We develop a Bayesian nonparametric framework for modeling ordinal regression relationships which evolve in discrete time. The motivating application involves a key problem in fisheries research on estimating dynamically evolving relationships between age, length and maturity, the latter recorded on an ordinal scale. The methodology builds from nonparametric mixture modeling for the joint stoch...

Knowledge of when critical crop stages occur and how the environment affects them should provide useful information for crop management decisions and crop production models. This research evaluated two sources of data for predicting dates of silking and physiological maturityof corn (Zea mays L.). Initial evaluations were conducted using data of an adapted corn hybrid grown on a Typic Agriaquol...

This research focuses on the drivers of e-government (E-gov) maturity in two comparable developing regions of the world i.e. Latin America and Sub-Saharan Africa (LA&SSA). E-gov maturity refers to the growth levels in a country’s online services and its citizens’ online participation in governance. To date, few researchers have focused on the drivers of E-gov maturity in LA&SSA. Given the chall...
