Methods: In this retrospective study, we analyzed demographics, surgical pathological data, postoperative complications biochemical results including calcium, phosphorus parathyroid hormone (PTH) levels patients who undertaken operations. Results: Totally 288 consecutive operated for diseases we...

My research is motivated by the idea that mathematical models can provide insight into the design of computer systems. My goal is to strip away the complexities of real systems, isolate the important components, and then develop models that characterize the impact of design decisions on the system as a whole. In order to accomplish this goal, I apply analytic models and tools that are tradition...

Five clinically normal chickens from three farms (farm A, farm B, and farm C), for a total of 15 clinically normal chickens, were examined bacteriologically. In a similar manner, five dead chickens with lesions of peritonitis from each of the same three commercial egg-laying operations were selected for bacterial culturing. Escherichia coli were isolated from the cloaca in 14 of 15 healthy chic...

More than a decade of observations of dairy operations in Hawai‘i suggested that there were more black cows in the local dairy herds than white cows. Hence, the objective of the study was to investigate if hair coat color affected productive life of Holstein cows in the sub-tropics. Two large herds within 2,000 meters of each other in the Waianae Coast district were used. Lactating cows were cl...

OBJECTIVES Exposure to environments rich in microorganisms such as farms has been shown to protect against the development of childhood asthma and allergies. However, it remains unclear where, and how, farm and other rural children are exposed to microbes. Furthermore, the composition of the microbial flora is poorly characterised. We tested the hypothesis that farm children are exposed indoors...

A vulnerability approach to climate change adaptation research is employed to explore prospects of agricultural adaptation to climatic variability and change. The methodological approach focuses on the system of concern, in this case, farms in Perth County, Ontario. Twenty-five interviews and four focus groups with farmers were used to identify climate risks on farms, and to document farmers’ r...

INCE 1974, FOLLOWING PUBLICATION of Schuh’s “The Macroeconomics of Agriculture,” much research effort has been devoted to determining whether and how monetary policy affects the farm sector. One of the more active areas of interest has been the question of whether changes in the money stock affect the farm! nonfarm product relative price ratio. The reason for this particular interest, as descri...

Income from off-farm sources is especially important for land-poor households. However, the pattern of participation in off-farm activities is heterogeneous across space. We explore the determinants of participation in off-farm non-agricultural employment using data for rural Mexico. In particular, we try to understand how the neighborhood and the neighbors’ characteristics and choices affect t...
