The world is occupied by seventy percent of water. Only a fraction of this water is considered to be safe for our usage. Within this fraction, most of the usable water is in the form of ice caps, glaciers and surface water. Thus, water being an essential element to human life poses as a concern when dealt with scarcity or availability. That being said, Pakistan faces a severe national problem because of its water crisis; amassing diverse factors which strengthen its roots. On an individual level
There are two kinds of alpacas – the Huacaya and the Suri. Huacaya are far the most frequent, representing 90 % of the Peruvian herd and undoubtedly the most in North America. Huacaya fur generates from the alpaca’s body is described by the crimp and loft. The Suri has fur that drapes from their body in pencil-sized ringlets. Although lacking in the crimp of the Huacaya fiber, Suri fiber’s smoother fiber shaft gives the fiber a more lustrous look and a smoother handle. “The alpaca is a member of
unanimous operational definition, this being indicative of the numerous screening tools available for the identification of frailty. The operationalization of frailty relates directly to the determinants used, determinant in this case referring to a characteristic whose presence in a patient may precipitate a diagnosis of frailty. It is important to note that determinants of frailty vary between screening tools thus allowing clinicians or researchers select tools that best suit their unique needs.3 This
A nurse must understand the developmental level of a client to better assist them in providing the best quality of care. This is so important to understand the different levels of development and to be able to identify the clients level of knowledge. This will allow the nurse to promote healing and proper well-being for that child. Adolescents may be able to understand what is going on a little better, but yet parents are still the guardian and make the final decision. The pediatric nurse must continually
The drought and the dust storms, were a one of the reasons for the poor farming in the Great Plains. Because of the droughts the soil became very dry and unfertile. This area, known as the Dust Bowl, was a location of dust storms during the 1930's. The storms accompanied the drought and intensified the farmer’s problems. With the drought many of the fields weren’t great for growing crops. As a result the fields were so
Though heat shock proteins (HSPs), the molecular chaperones that stabilize folding of other proteins are mainly induced during temperature stress, some of them are also induced during drought stress. Membrane-stabilizing proteins and late embryogenic abundant proteins are another class of proteins that confer drought tolerance in certain plants. TEMPERATURE STRESS – All organisms including plants require an optimum temperature range for proper growth. There is an upper and lower limit also at which
that turn day into night, blasting sand and soil, huge sand storms hundreds of miles wide and miles high lasting anywhere from an hour to a day. There is no hiding for people in the path of these storms, only waiting for the wind to die and these droughts to cease, but the rains do not bring any relief. Instead, flash floods strip barren fields of precious minerals within the soil, leaving more dust to form larger, blacker clouds for next growing season. Land degradation is a combination of man made
1 Introduction Sustainable agriculture approach has been developed and diffused in the recent decades because of the concerns about the negative impacts of modern agriculture on human health, the natural environment and resources. This approach that not only makes better use of natural goods and services for human needs without damaging the environment, but also minimizes the use of external inputs. Moreover, it enables farmers to more effectively use their knowledge and skills (Duesterhaus 1990;
1-Abstract: Health is an important aspect of human wellbeing. It improves the capabilities of people who recognized as the end mean of development. The ability to live longer and healthier is also found as a basic human right. But the toxic chemicals emission due to human activities causes the direct exhaustion of earth’s ozone layer which affects at least three basic requirements for maintaining good health: clean air, water, and food. The climate in Pakistan is slowly but surely changing. This
The Effect of Climate Change on the Golden Toad Introduction Throughout history the Earth’s climate continually cooled and warmed with weather regimes changing. This natural process is being enhanced through human activities that are increasing the warming of the atmosphere at a more rapid rate than previously seen. Among the many threats to biodiversity; the destruction of habitats, population growth, pollution, invasive species and overexploitation, climate change is having an adverse effect on
