This paper combines the use of the Harris index and the relative damping index (RDI) to give a new method for CPM-based controller tuning. The RDI is defined based on the disturbance impulse response, which is calculated as a byproduct of the Harris index. The proposed technique provides controller settings that attain the best-achievable performance by careful and systematical changing of cont...
BACKGROUND Early Antarctic expeditions were plagued by nutrient deficiencies, due to lack of fresh food and reliance on preserved foods. Modern Antarctic expeditioners also require provisions to be shipped in, but improved knowledge and storage options ensure foods are nutritionally sound. Despite this, nutritional imbalances are observed. OBJECTIVES To determine the adequacy of dietary intak...
CONTEXT Sleep abnormalities, including obstructive sleep apnea (OSA), have been associated with insulin resistance. OBJECTIVE To determine the relationship between sleep, including OSA, and glucose parameters in a prospectively assembled cohort of chronically sleep-deprived obese subjects. DESIGN Cross-sectional evaluation of a prospective cohort study. SETTING Tertiary Referral Research ...
This study looked at regulated deficit irrigation (RDI) on leafhoppers in the genus Erythroneura (Erythroneura elegantula Osborn, or western grape leafhopper, and Erythroneura variabilis Beamer) (Hemiptera: Cicadellidae), which are serious pests of cultivated grape (Vitis vinifera L.) in California. RDI is an irrigation strategy that reduces irrigation during a critical point in the phenology o...
BACKGROUND There are few reports about sleep disturbances in patients with chronic obstructive pulmonary disease (COPD) in Asian countries. OBJECTIVES To investigate the associations between sleep-disordered breathing (SDB) with hypoxemia and sleep quality, including sleep duration, in patients with COPD, we measured SDB and sleep quality including the objective sleep duration determined by a...
تاکنون شاخص‌های متعددی توسط محققان مختلف برای بررسی پدیده خشکسالی معرفی و استفاده شده‌اند که هر کدام به فراخور شرایط منطقه و پارامترهای تاثیرگذار بر خشکسالی، دارای توانایی‌ها و نواقصی خواهند بود. طی سال‌های اخیر شاخص خشکسالی اجمالی (RDI) بدلیل در نظر گرفتن توام بارش و تبخیر و تعرق، با استقبال بیشتری نسبت به سایر شاخص‌ها روبرو بوده و گاهاً مبنای مقایسه شدت خشکسالی و برآورد خسارات بالقوه آن در سطح...
Potato consumption provides significant dietary contributions to several essential minerals, but the effects of cultivar and planting site are not well-understood. The mineral content of 16 cultivars, grown at 5 locations, was measured using inductively coupled plasma-optical emission spectroscopy and evaluated on a per serving basis for percent recommended daily intake (% RDI), emphasizing som...
شاخص RDI از برازش توزیع لوگ‌نرمال بر مقادیر نسبت بارندگی (P) به تبخیر و تعرق پتانسیل (ETo) در هر بازة زمانی دلخواه به‌دست می‌آید. در این شاخص مقدار ETo از روش ترنت‌وایت (Th) و بر اساس دمای میانگین محاسبه می‌شود. روش Th مقدار ETo را در مناطق خشک و نیمه‌خشک کمتر از مقدار واقعی تخمین می‌زند. همچنین، در برخی از مناطق ممکن است توزیع لوگ‌نرمال نتواند مناسب‌ترین توزیع بر مقادیر نسبت بارندگی به ETo ...
Abstract Elevated temperatures during berry ripening are detrimental to grape quality. The crop forcing technique (summer pruning that ‘forces’ the vine start a new cycle) increases must acidity and malic acid concentration at harvest by delaying date of veraison. However, little information is available on sensitivity water stress forced vines. A 3-year trial was conducted test three irrigatio...
We performed a flow cytometric (FCM) analysis of the maturity of reticulocytes using peripheral blood obtained from rats administered 5-fluorouracil (5-FU) at 10, 50 and 100 mg/kg or acethylphenyl hydrazine (APHZ) at 1 and 3 mg/kg to clarify whether the FCM method is useful for assessing toxicity. In the 5-FU-administered rats, a decrease and recovery of the immature reticulocyte fraction (Cell...
