In order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, Ardabil, Iran, in 2007. Experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

in order to investigate the effect of irrigation intervals and harvesting time on yield and yield components of anise (pimpinella anisum l.) a field experiment was conducted at the agricultural research station, university of zanjan in 2010. for this purpose a spilt-plot experiment based on complete randomized block design with three replications was used. three irrigation intervals (every 7, 1...

the effect of grain size, tailwater depth and grain froude number on local scour caused by submerged horizontal jets issuing below a sluice gate was investigated. noncohesive sediments with two gradations downstream of a horizontal apron were used in the experiments. the experiments were carried out at different inflow froude numbers and a range of tailwater depth from low to high submergence. ...

In this note, steps in order to write a formula that gives the total number of subgroups of a finite abelian group are made.

Contact networks are often used in epidemiological studies to describe the patterns of interactions within a population. Often, such networks merely indicate which individuals interact, without giving any indication of the strength or intensity of interactions. Here, we use weighted networks, in which every connection has an associated weight, to explore the influence of heterogeneous contact s...

Third generation wireless system is based on the WCDMA access technique. In this technique, all users share the same bandwidth simultaneously but with different codes. So in Soft Handoff (WCDMA) new user will demand new OVSF codes. This behavior effectively reduces the total number of available OVSF codes in each cell. The effective available OVSF codes in each cell decreases as the percentage ...

The self-employed represent a significant percentage of the total number of Latin American workers. According to estimates of the International Labor Organization for 2016, they make up approximately 31% of the total number of workers, exceeding 40% in some countries. Thus, their inclusion in the pension systems is crucial for them to receive the same degree of protection in old age as dependen...

After 1948 the Romanian higher education entered a period of important developments, controlled by the communist regime, which meant thathigher educationinstitutions autonomy was severely obstructed, while politicalpurges affected the teaching staff and students alike. Nevertheless, new types of higher education were introduced and new institutions of higher education and specializations were e...

The author analyzes changes in the rate of migration and choice of destination among migrants from socialist countries in eastern and southern Europe to the United States and Canada during the period 1941-1990. "The data presented show that in the period in question the immigrants from the European socialist countries constituted only 2.9% of the total number of immigrants to the U.S.A. while ...
