It can reduce overproduction, increase effective demand and facilitate the balance between the demand and supply, and prevent the frequent occurrence of economic crisis. All the creatures of the God are there for a reason. The amount of production is based on the amount of currency. But some parts of currency are transformed into savings, and savings cannot be turned into investment immediately. The entailing overproduction breaks the balance between the demand and supply, and results in economic crisis. In modem society, it is the social security or those ＂lazy bones＂ that represses and eliminates the overproduction, which can be expressed by the equation： Savings = Investment ＋ Social security （consumption）. In this way, the balance between the demand and supply is realized.and the social production and life can continue in a normal way.展开更多

Assessment was done by means of multistage random sampling. The homestead sizes of the study area were classified into 3 groups viz, large （〉0.25 ha）, medium （0.05-0.25 ha） and small （〈0.05 ha） based on the result obtained from a preliminary survey, and a total of 45 homesteads, 15 from each group, were selected randomly for the study. The average annual income from homestead＇s plant diversity varied from Tk 5730.00 （US$95.5） to Tk 17500.00 （US$291.67）. The rural people were mainly dependent on their homegarden for woodfuel and nutritional requirement as forest was unavailable in the island. The rural people here also cultivated the plant species as a safety measure from frequent cyclone. Constraints hindering the development of homestead plantation were identified and suggestions were given such as the adequate supply of seedlings of fast growing native species and conservation of endangered species to meet the demand of the household as well as to keep ecological balance.展开更多

It presents a geographical coordinate system, habitats, phenology, and economic values. The distribution of species in Uzbekistan was indicated by the phytogeographic regions of the country. The herbarium material of Gagea Salisb. has been studied in TASH, SAMSU and MSU. The TASH Herbarium presents samples from 1914 to 2019. The review was written using information published between 1988 and 2019 from a number of reliable sources, including Science Direct, Springer, PubMed, EMBASE and Wikipedia.展开更多
