Many students with ADHD have significant difficulties with organization.    They are more likely to respond positively when teachers establish class routines and set procedures and maintain a well-organized learning environment.    Clear rules and advanced planning are keys to success for teachers of students with ADHD. The following organizational supports are particularly useful. Students should be taught to use these tools through teacher modeling and guided practice with feedback before being expected to use them more independently. Assignment Notebook: Provide the student with an assignment notebook to helporganize homework and seatwork.Color-Coded Folders: Provide the student with color-coded folders to helporganize assignments for different academic subjects.Homework Partners: Assign the student a partner who can help recordhomework and other seatwork in the proper folders and assignment book.Clean Out Dates: Periodically ask the student to sort through and clean out his orher desk, book bag, and other special places where written assignments are stored.Extra Books: Provide the student with an extra set of books or electronicversions of books for use at home. This eliminates the student having toremember to bring books back and forth.Use of Calendars: Teach the student to use a calendar for schedulingassignments. Tape a schedule of planned daily activities to the student’s desk tohelp with time management and transitions.Checklist of Homework Supplies: Give the student a checklist that identifiescategories of items needed for homework assignments. The checklist can betaped to the inside of the student’s locker or desk.  Read more

Quality traits in aquaculture Aquaculture species are reared for particular traits such as growth rate, survival rate, meat quality, resistance to diseases, age at sexual maturation, fecundity, shell traits like shell size, shell colour, etc. Growth rate – growth rate is normally measured as either body weight or body length. This trait is of great economic importance for all aquaculture species as faster growth rate speeds up the turnover of production.[19] Improved growth rates show that farmed animals utilize their feed more efficiently through a positive correlated response.[18] Survival rate – survival rate may take into account the degrees of resistance to diseases.[18] This may also see the stress response as fish under stress are highly vulnerable to diseases.[19] The stress fish experience could be of biological, chemical or environmental influence. Meat quality – the quality of fish is of great economic importance in the market. Fish quality usually takes into account size, meatiness, and percentage of fat, colour of flesh, taste, shape of the body, ideal oil and omega-3 content.[18][ Read more

Plant breeding Plant breeding has been used for thousands of years, and began with the domestication of wild plants into uniform and predictable agricultural cultigens. High-yielding varieties have been particularly important in agriculture. Selective plant breeding is also used in research to produce transgenic animals that breed "true" (i.e., are homozygous) for artificially inserted or deleted genes.[1 Read more

Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds.[1] Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. Read more

isotope labeling agents Agriculture is the science and art of cultivating plants and livestock.[1] Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Pigs, sheep and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture into the twenty-first.

Child marriage is a marriage or similar union, formal or informal, between an adult and a child or youth under a certain age, typically age eighteen. Child marriage violates the rights of children and has widespread and long term consequences for child brides and grooms. It affects both boys and girls, but it is more common among girls.The legally prescribed marriageable age in some jurisdictions is below 18 years, especially in the case of girls.[citation needed] Even where the age is set at 18 years, cultural traditions may take priority over legislative law and many jurisdictions permit earlier marriage with parental consent or in special circumstances, such as teenage pregnancy. Comprehensive sex education can help to prevent child marriage.[ Child marriage is related to child betrothal, and it includes civil cohabitation and court approved early marriages after teenage pregnancy.[7][8] In many cases, only one marriage-partner is a child, usually the female. Causes of child marriages include poverty, bride price, dowry, cultural traditions, laws that allow child marriages, religious and social pressures, regional customs, fear of remaining unmarried, illiteracy, and perceived inability of women to work for money.[2][9] Read more
