primary bud necrosis in grapevine is a physiological disorder observed in the compound buds. this study was conducted to investigate the anatomical changes in cv. askari grapevine in winter dormant buds. bud samples were taken from askari grapevine at sisakht vineyards, south-western of iran. compound buds were dissected and assessed under a binocular microscope at 10-40x magnification and a di...

background: the termination of pregnancy before 20 th week of gestation is abortion. there is two type of abortion: spontaneous and induce (legal or illegal). the annual number of pregnancy in the world is estimated over 200 million and one third of them is unwanted pregnancy. 95% of unwanted pregnancy is happened in developing country such as iran. in iran, the high prevalence of unwanted preg...

We offer evidence that legalized abortion has contributed signiŽcantly to recent crime reductions. Crime began to fall roughly eighteen years after abortion legalization. The Žve states that allowed abortion in 1970 experienced declines earlier than the rest of the nation, which legalized in 1973 with Roe v. Wade. States with high abortion rates in the 1970s and 1980s experienced greater crime ...

CONTEXT Accurate information about abortion incidence and services is necessary to monitor levels of unwanted pregnancy and women's ability to access abortion services. METHODS All known abortion providers in the United States were contacted for information about abortion services in 2004 and 2005. This information, along with data from the U.S. Census Bureau, was used to examine national and...

BACKGROUND While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated...

BACKGROUND AND AIMS In trees, bud development is driven by endogenous and exogenous factors such as species and climate, respectively. However, knowledge is scarce on how these factors drive changes in bud size across different time scales. METHODS The seasonal patterns of apical bud enlargement are related to primary and secondary growth in two coexisting Mediterranean oaks with contrasting ...

BACKGROUND Malaysia has relatively liberal abortion laws in that they permit abortions for both physical and mental health cases. However, abortion remains a taboo subject. The stagnating contraceptive prevalence rate combined with the plunging fertility rate suggests that abortion might be occurring clandestinely. This qualitative study aimed to explore the experiences of women and their needs...

A new sort of combinatorial generating system, called bud generating system, is introduced. Bud generating systems are devices for specifying sets of various kinds of combinatorial objects, called languages. They can emulate context-free grammars, regular tree grammars, and synchronous grammars, allowing to work with all these generating systems in a unified way. The theory of bud generating sy...

it is necessary to determine the amount of chilling requirement of present cultivars and also to produce new low chill cultivars through breeding programs because of the global warming phenomenon and tendency to grow temperate fruit in warm climate. in this study, the amount of chilling requirement in ‘askari’, ‘rotaby’, ‘yaghuty’, ‘rish baba’ and ‘monaga΄ were evaluated. uniform cuttings of me...
