Ice Cream Dessert

...Chapter I Introduction Ice cream is a frozen dessert usually made from dairy products, such as milk and cream, and often combined with fruits or other ingredients and flavors. Most varieties contain sugar, although some are made with other sweeteners. In some cases, artificial flavorings and colorings are used in addition to the natural ingredients. Philippines’ version for ice cream: Sorbetes is usually produced from unknown factories and sold from carts that roam the streets, exposing it to pollution. Thus, it is also called dirty ice cream; though it is not really dirty as the name implies. Kids love ice cream, and so do grown-ups, but to indulge in this frozen delight can mean a lot of fat and calories, depending on the choices. The calories in a cup of ice cream can vary anywhere from 180 to 600, depending on brand, fat content, sugar content, and flavor. Nonfat or fat-free ice creams contain virtually no fat: vegetable gums are added to make them creamy and mixtures are made in soft serve machines to whip in additional air and ice crystals. Most nonfat ice creams contain 90 to 100 calories per half cup but not all, leaving health-conscious consumers, who avoid calories and fat, fewer options, or none at all. A newly industrialized country, the Philippine economy has been transitioning from one based on agriculture to one based more on services and manufacturing. Despite this, the agricultural sector employs close to 32% of the country's total labor force of around...

However, little is known about the influence of changing norms and values on men’s role in ensuring women’s health during pregnancy and childbirth. This study from rural south-eastern Tanzania explores men’s and women’s discussions on men’s roles and responsibilities in prenatal care and links them to an analysis of norms and values at the household level and beyond. Data from eight focus group discussions with men and women were consensually coded and analysed using a qualitative content analysis. Four dimensions of norms and values, which emerged from analysis, bear upon men’s support towards pregnant women: changing gender identities; changing family and marriage structures; biomedical values disseminated in health education; and government regulations.

...http://cls.casa.colostate.edu/transgeniccrops/what.html What Are Transgenic Plants? A transgenic crop plant contains a gene or genes which have been artificially inserted instead of the plant acquiring them through pollination. The inserted gene sequence (known as the transgene) may come from another unrelated plant, or from a completely different species: transgenic Bt corn, for example, which produces its own insecticide, contains a gene from a bacterium. Plants containing transgenes are often called genetically modified or GM crops, although in reality all crops have been genetically modified from their original wild state by domestication, selection and controlled breeding over long periods of time. On this web site we will use the term transgenic to describe a crop plant which has transgenes inserted. Image:Results of insect infestation on Bt (right) and non-Bt (left) cotton bolls. Source: USDA | Why Make Transgenic Crop Plants? A plant breeder tries to assemble a combination of genes in a crop plant which will make it as useful and productive as possible. Depending on where and for what purpose the plant is grown, desirable genes may provide features such as higher yield or improved quality, pest or disease resistance, or tolerance to heat, cold and drought. Combining the best genes in one plant is a long and difficult process, especially as traditional plant breeding has been limited to artificially crossing plants within the same species or with closely related...
