Soil Erodibility Factor (K) The soil erodibility factor (K), a measure of the susceptibility of soil to erosion under standard conditions, is a function of the percentage of silt and coarse sand, the soil structure, the permeability of the soil, and the percentage of organic matter. Wischmeier et al. (1971) defined the soil erodibility factor mathematically and Foster et al. (1996) converted the equation into the following SI unit equation: The soil erodibility factor (K) is determined for each soil sample based on analysis of soils in laboratory. The equation (Wischmeier and Smith, 1978) mentinoned is below. K = ((2.17 × 10-4) × (M1.14) × (12-a) + 3.25 × (b - 2) + 2.5 × (c - 3)) × d [5] where M = (percentage of silt and fine sand)…

Conditions such as uncleared drainage canals and a swampy soil in Kemar’s landscape are favorable to mosquito breeding and habitation. 2. On a broader level, stagnant water, excessive reeds, and extreme heat can also play a role in the increased mosquito breeding. Specifically, tropical regions are typical breeding grounds for mosquitos thanks to acute water presence from rain. 3. Shanae’s illness could be caused by the increasing number of mosquitos she has been exposed to, some of which cary…

27. What is a Difference between Lifeless and Animated Matter? • There are two aspects of life. When we perceive something as ‘substance’ it is in reality something “living” from “THE ASPECT OF SUBSTANCE”. When we perceive something as alive it is, in reality, the substance we see from “THE ASPECT OF LIFE”. The ability to feel life from “THE ASPECT OF SUBSTANCE” have PRIMITIVE stages of development. The ability to SENSE The Substance from “THE ASPECT OF LIFE” have beings on the threshold of “The…

Figure 1: This line graph represents the prune’s weight in grams, in each beaker, over time. The prunes initial weight were all different, ranging from the heaviest prune in Beaker A, middleweight in Beaker B, and lowest weight in Beaker C. The weight of the prune in Beaker A increased at the fastest rate, followed by Beaker B and then Beaker C. Figure 2: This line graph represents the temperature of the water in each beaker, over time. The water’s initial temperature were all different,…

“Katie slipped on a pair of beat- up converses sneakers. The chest of drawers stood largely empty and there was almost no food in the kitchen but as she stepped out of the house and into the sunshine and headed towards the store, she thought to herself, this is home. Drawing in a deeply scented breath of hyacinth and fresh- cut grass, she knew she hadn't been happier in years “ . (Sparks) Katie is finally happy she found a safe haven, safer place to live. Katie is learning to be independent and…

41. What is the Innermost Essence of ‘MATERIALIZATION’ & ‘DEMATERIALIZATION’? • An average Terrestrial Man was puzzling and at the same time fascinated by phenomena of Materialization or Manifestation which is Appearance or Creation of (Living) Matter from an unknown source, and even more with ‘Teleportation’. The last is Dematerialization and Re-materialization which is a ‘transfer’ of Matter or Living Body from ‘point A’ to ‘point B’ without traversing Physical space between them. Per…

Throughout the story we see a correlation between the imagery that is used to describe the summer house and the narrators mental state. The very first thing we are introduced to is the house and how beautiful it is, yet she describes it to have an intangible quality that is off putting to the narrator. We then learn of her condition, diagnosed by her husband as “temporary nervous depression”, and get our first glimpse of her oppressive relationship leaving you with the feeling that there is…

First, subjects were all college-aged students with psychological backgrounds. While using an age of subjects that are functional social media experts gives this study more internal validity, it may prove differently had we used the oft highly opinionated moms and grandmothers on Facebook, or conversely with high school and middle school aged children. Another limitation we faced was the ability to control for the face-to-face conversation. Subjects were given the listed topics to guide…
