  • Diversity of plant form and life history and their distribution onto different habitats suggest that plant functions should underlie this diversity, providing tools to successfully and differentially thrive in every habitat. The knowledge of these functions is then the key to understand community and ecosystem structure and functioning, something that attracted the interest and effort of many plant ecologists trying to establish patterns of adaptive specialization in plants.

  • Research show that RVT doesn’t has any side effect on fertility. In 200 cases of pregnancy after RVT 66% lead to neonate birth. Premature birth before 37th week happened in 27% of the cases. Abortion rate in first trimester was 16-20% like general population and second trimester abortion was 9.5% (Plante et al., 2005; Jolley et al., 2007). If the tumor volume is less than 500mm, tumor size is less than 2 cm and invasion depth of stroma is less than 2mm we can do ultraconservative operations include simple trachelectomy or extensive conization with knife. In this...

  • Microbial biomass formation on root surfaces can be measured in plants growing in solution with or without an inert solid support. Carbon flow to the biomass can be measured by growing plants in solution or soil on a continuous source of 14C02 and the expected biomass formation predicted. The lack of correlation between measured and predicted biomass can be explained by oligotrophic growth of the micro-organisms.

  • IN CHAPTER 5 WE DISCUSSED plants’ requirements for mineral nutrients and light in order to grow and complete their life cycle. Because living organisms interact with one another and their environment, mineral nutrients cycle through the biosphere. These cycles involve complex interactions, and each cycle is critical in its own right. Because the amount of matter in the biosphere remains constant, energy must be supplied to keep the cycles operational. Otherwise increasing entropy dictates that the flow of matter would ultimately stop.

  • The heat radiation from gas flaring greatly affects the surrounding environment and particular crops planted within the vicinity of gas flare stations (Abdulkareem and Odigure, 2002). It also has a devastating effect on microorganisms and aquatic life. Heat radiation from gas flaring also causes an increase in heat waves hence there is the possibility that habitants of Niger-Delta Area, where the gas flaring stations are located will suffer heart stroke, heart attacks and other ailments aggravated by the heat (Odigure et al., 2003).

  • There are many phenomenologicalmodels of inflation in the literature,which usually employ some new fields and new interactions. It is, therefore, quite reasonable and meaningful to search for the minimal inflationary model building, by getting most economical and viable inflationary scenario. I amgoing to use the one proposed the long time ago by Starobinsky (20; 21), which does not use new fields (beyond a spacetime metric) and exploits only gravitational interactions. I also assume that the general coordinate invariance in spacetime is fundamental, and it should not be sacrificed.

  • One way scientists find out about the world is by asking questions. Science is an organized way of studying things and finding answers to questions. There are many types of science. The names of the sciences describe what is being studied. For example, a life scientist might study the millions of different animals, plants, and other living things on Earth. Life scientists who study plants are botanists. Those who study animals are zoologists.

  • is told in Malvern Chase that Mary of Eldersfield (1454), "whom some called a witch," famous for her knowledge of herbs and medicaments, "descending the hill from her hut, with a small phial of oil, and a bunch of the 'Danewort,' speedily enabled Lord Edward of March, who had just then heavily sprained his knee, to avoid danger by mounting 'Roan Roland' freed from pain, as it were by magic, through the plant-rubbing which Mary administered.

  • Animal parts are generally easier to identify than plants but only if they have not been processed. For example, many ingredients such as rhinoceros horn and elephant ivory are obvious if whole but if they are processed into shavings or powder then it is impossible to identify them by eye. For most processed material forensic analysis is probably the only option if the items are not labelled. The types of animal parts to look out for are bones, horns, tusks, gallbladders, shells and fur-covered glands (see section on fakes below).

  • The effects of Meloidogyne incognita, Xanthomonas campestris, and Rhizobium sp., alone or in combination, on the disease complex in chickpea were examined. Individual inoculation with M. incognita and X. campestris caused significant reductions in plant growth, while inoculation with Rhizobium sp. resulted in a significant increase in plant growth.

  • Sowing date, plant density and harvest date are important factors affecting root yield and quality of sugar beet (Beta vulgaris L.). The effects of sowing date (beginning of April, mid-April, the end of April, mid-May, and the end of May), plant density, and harvest date (the end of September and mid-October) on sugar beet yield and quality were studied in trials in the Eastern Anatolia region on a loam soil in 1994-97.

In this study, a suppression subtractive hybridization (SSH) library was constructed to study differential gene expression in banana plants mediated through a Fusarium wilt pathogen (Fusarium oxysporum f.sp cubense – Foc) and its interaction with the Foc effective biocontrol agent Trichoderma asperellum (prr2). Here cDNAs from the roots of banana cv.

  • In contrast to other animals, humans sense their world chiefly by vision, sound, and touch. We have, in general, a remarkably undeveloped sense of smell, and so it is not surprising that we fail to appreciate how important chemical signals are in the lives of other organisms. Chemical signals and cues serve insects in numerous ways, including sexual advertisement, social organization, defense, and finding and recognizing resources.

  • During the past two centuries, scientists, farmers, and agricultural educators have tended to alternate their views of soil organic matter (SOM) between the extremes of great appreciation and low esteem. As an early 20th century bulletin explained, organic matter was “once extolled as the essential soil ingredient, the bright particular star in the firmament of the plant grower…” before it “…fell like Lucifer…” as a result of the findings of 19th century agricultural chemists that most of the plant structure (C, that is) originated in the atmosphere (Hills et al., 1908)....

  • Through the studies, we can deduce that most of the industrial discharge carries toxic substances. Due to the presence of high amount of toxic, carcinogen, and teratogen of metals, researchers are highly concerned with its effect on the environment and health of mankind. Rigorous investigations are currently being carried out to study the consequences of the contamination on the surface water, groundwater, and surface land due to industrial discharge.
