This paper briefly reviews earlier as well as recent approaches of Indian Social Stratification System and there relevance in present era. Much of what is known about Social Stratification in India is based on studies conducted in early and middle part of the 20 th century. There is a lot of literature available on the theme of social stratification in India. In fact, the most researched area i...

Risk stratification for any disease is, in many ways, medicine’s attempt to predict the future. The challenges in risk stratification for sudden death, however, may be unparalleled in medicine. Although the many types of sudden death all present with similar phenotypes, risk stratification efforts generally center on the prediction of death resulting from either ischemic or arrhythmic events. T...

To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...

Methods: A risk stratification tool provided HIV (N) PEP clinical decision guidelines and framework for use with adult survivors. Forensic and emergency department nurses (n=20 total) were given a pre-training knowledge assessment. Forensic nurses (n = 6) were given specific training in HIV risk stratification and use of the (N) PEP decision guideline tool. Knowledge scores were assessed immedi...

OBJECTIVES To explore classification rules based on data mining methodologies which are to be used in defining strata in stratified sampling of healthcare providers with improved sampling efficiency. METHODS We performed k-means clustering to group providers with similar characteristics, then, constructed decision trees on cluster labels to generate stratification rules. We assessed the varia...

Echinochloaoryzicola(syn.E. phyllopogon) is an exotic weed of California rice paddies that has evolved resistance to multiple herbicides. Elimination of seedlingsthroughcertain weed control methods can limit the spread of this weed, but is contingent on accurate predictions of germination and emergence timing, which are influenced by seed dormancy levels.In summer annuals, dormancy can often be...

in order to find the most effective method to overcome seed dormancy in teucrium chamaedrys  l. medicinal plant species the effect of some chemical and physical breaking methods including: cold stratification (5 °c), scarification with sandpaper, stratification with needle, concentrated sulfuric acid, gibberellic acid and combination of these methods were investigated. treated seeds along with ...

Soil quality is a concept based on the premise that management can deteriorate, stabilize, or improve soil ecosystem functions. It is hypothesized that the degree of stratification of soil organic C and N pools with soil depth, expressed as a ratio, could indicate soil quality or soil ecosystem functioning, because surface organic matter is essential to erosion control, water infiltration, and ...

The effect of stratification on dormancy release of grape seeds crossing from the sub- to the supraoptimal range of temperatures and water contents was analysed by modified threshold models. The stratification impacted on dormancy release in three different ways: (i) dormancy was consistently released with prolonged stratification time when stratified at temperatures of <15 degrees C; (ii) at 1...
