Studying plant phenology is very important to regulate the rangeland utilization. Plant phenology can be determined by Growing Degree Days (GDDs). Since temperature varies yearly, the phenological stages may consequently differ yearly. Determining the base temperature is one of the key steps in the calculation of GDDs. The aim of this study was to calculate the required GDDs for each phenologic...
Forecast of tree fruit yield requires prediction harvest time size as well number. Mango (Mangifera indica L.) mass can be estimated from correlation to measurements length (L), width (W) and thickness (T). On-tree individually tagged were undertaken using callipers at weekly intervals until the past commercial maturity, judged growing degree days (GDD), for mango cultivars ‘Honey Gold’, ‘Calyp...

one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Plant phenology, i. e. the timing of life cycle events, is related to individual fitness and species distribution ranges. Temperature one most important drivers plant phenology together with day length. The adaptation their may be for success invasive species. present study aims at understanding how performance legume Lupinus polyphyllus vary latitude. We sampled data across a >2000 km l...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
Snap bean, a warm-season crop, have low frost tolerance. The optimal temperature for seed emergence and plant growth is important. Therefore, appropriate planting dates adapted varieties has paramount significance in improving pod yield quality of snap bean under short cool season climates. Three cultivars planted at 3 different were examined to evaluate the effects on traits 2-year study clima...
