objective: returning crop residue to the soil exerts favorable effects on physical and chemical properties of soil. in fact, the plant residues can affect soil conditions such as ph and important role in soil fertility and cycling of elements in the soil may have. in addition to the role of the organic matter from decomposition of crop residue in increasing the concentration of micronutrients i...

BACKGROUND Many individuals with type 2 diabetes in emerging countries are transitioning from vial-and-syringe insulin delivery to that of insulin pens (disposable or reusable). As with all insulin delivery methods, patient preferences and comfort are of utmost importance to optimize adherence to treatment. Patient-preferred characteristics for reusable insulin pens and barriers to appropriate ...

We report results from HST-NICMOS imaging of the extremely dense core of the globular cluster Terzan 5. This highly obscured bulge cluster contains a low-mass X-ray binary and at least two millisecond pulsars, with evidence for a large millisecond pulsar population. It has been estimated to have one of the highest collision rates of any galactic globular cluster, making its core a particularly ...

Bob drives to work every morning. On each day t, he picks one of many possible routes, and suffers some some delay dt. The traffic pattern changes from day to day, so some routes may be congested and others wide open, but Bob has no way of knowing this before hand. After returning home in the evening, he gossips with his neighbors/colleagues, each of whom has chosen a different path to work, an...

T he therapeutic potential of stem cell treatment for patients with either acute myocardial infarction (AMI) or heart failure (HF) began >15 years ago. Many preclinical studies have been published demonstrating stem cell administration improves myocardial function in animal models of AMI and of HF. Parallel results were found in many small phase 2 clinical trials. However, the results of more r...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

The effects of superatmospheric oxygen levels on anthocyanins, phenolics, antioxidant activity and fruit quality of blueberries (Vaccinium corymbosum L.) and strawberries (Fragaria × ananassa Duch.) during storage at 5°C were investigated. High oxygen treatment increased the levels of total anthocyanins, total phenolics as well as several individual flavonoid compounds during the first 21 days ...

Fruit extracts from 17 to 18 representatives of three strawberry species IFragaria virginiana Mill., F. clz:Ioensi.s(L.) Mill., and J' xa,,a,za,ssa Duchesne ex Rozierl were tested for the ability to inhibit proliferation of A549 human lung epithelial cancer cells. The fruit extracts also were tested for activities against free radicals, (peroxyl radicals, h ydroxyl radicals, singlet oxygen, and...

Teaching the next generation of engineers about the inner workings of GPS receivers is difficult due to the expense of acquiring appropriate hardware and software. In the past few years a number of excellent books have been written about GPS (references 1 through 5). But, in the end students learn best by doing. Even with hardware available, trying to squeeze the development of software into a ...
