Labyrinthine fistula, defined by a destruction of the bony labyrinth is one of the most feared complications during the evolution of a chronic otitis media with cholesteatoma. Relatively common, it represents 4-12% cases of chronic otitis media with cholesteatoma and essentially occurs in the lateral semi-circular canal (70-80% of cases). The abnormal opening of the bony labyrinth in the middle ear runs the risk of recurrent labyrinthitis with dizziness, sensorineural hearing loss, purulent labyrinthitis and meningitis. Its treatment is surgical, however, an alteration of cochleovestibular function during surgery may occur. We propose in this development to review signs that suggest this complication and to establish a practical management of labyrinthine fistula in chronic otitis media with cholesteatoma.

Abattoir wastewater has a complex composition and very harmful to the environment. There is always need for reduction in the impact of natural and most especially anthropogenic pollution to enhance water quality, food safety and sustainable development. Physico-chemical and microbial properties analysed using standard laboratory procedures were temperature, pH, conductivity, turbidity, total solid (TS), total dissolved solid (TDS), total suspended solid (TSS), dissolved oxygen (DO), acidity, alkalinity, total hardness, calcium and magnesium hardness, chloride, iron and nitrate. Temperature ranged from 28.04-29.12C, pH between was 7.67-8.01, Alkalinity is 0.45 mg/l, TS, BOD and TSS were 700 mm/l, 48 mm/l, 500 mm/l, DO is 2,100 ppm. Holistic outputs of the investigation revealed various water samples were contaminated with E. Coli and other enteric bacteria. The presence of coliform staphylococcus aures indicated the presence of microorganisms which are associated with water borne disease.

A survey on recent developments in the duality theory of sequence spaces has been done and duality in some Bicomplex sequence spaces is introduced which gives rise to sixteen types of different duals.

This paper studies the challenges in the current intrusion detection system and comparatively analyzes the active and passive response systems. The paper studies the existing IDS and their usefulness in detecting and preventing attacks in any type of network and control traffic with the performance of the system to be improved. The study also evaluates the emerging avenues in Intrusion Detection System and explores the possible future avenues in intrusion detection scheme. It is observed that the detection-based systems have started to gain popularity in the IT security domain. The paper highlights the need to implement an appropriately configured IDS since an optimally configured IDS deters hackers, thus, reducing the need for investigation by security experts for security violations.

Purpose – The purpose of this study is to identify and describe the characteristics of literature published in the field of “KM” over the period of 8 years with a view to identify the place, language, year of publication, subject areas, forms of documents, country of origin etc. Design/methodology/approach – A total numbers of 4371 items are collected from the source document “Web of Science”, from the year 2007-2014. Findings – The overall productivity of Knowledge Management (KM) works has been growing, reaching up to 495 publications per year from 2007 to 2014, but their productivity are somewhat irregular. Most of the literature of KM in Web of Science is published in non KM focal journals. KM play a major role from the ancient time so there is differentiate in research by country wise. The most productive top five countries in the field of KM research are USA, England, Taiwan, Spain, and China.

Black cotton soils are predominantly available in India. Though black cotton soil plays a vital role in agriculture but it is posing many difficulties in civil engineering aspect. All the black cotton soils are not expansive soils and all the expansive soils are not black in color. These soils passed high strength in summer and decreased rapidly in winter. The soil has a swelling property due to the presence of montmorillonite mineral. Though various constructions techniques are utilized, the cracking (Minor Cracking) is seen in the buildings. For the site investigations, the behavior of soil is important. This paper gives information regarding bearing capacity and suitable foundations for different types of constructions in black cotton soils.

Ticks are among the obligated ecotparasites that feed blood of vertebrates; particularly mammals; birds; and they are arachnids in the subclass Acari; closely related to mites; surviving for up to several years. This review paper dials about the biology; epidemiology and control methods of hard ticks. Morphologically they are classified into two families known as Ixodidae and Argasidae. All hard ticks feed only on blood of their hosts. They are active during warm periods and easily find their hosts by grapping using their front legs and attach on the suitable site. In their life cycle they have three active stages called larvae; nymphs and adults after eggs is released which is dormant.

In this paper, we employ the exp (−φ(ξ))-expansion method to find the exact traveling wave solutions involving parameters of nonlinear evolution equations. When these parameters are taken to be special values, the solitary wave solutions are derived from the exact traveling wave solutions. It is shown that the proposed method provides a more powerful mathematical tool for constructing exact traveling wave solutions for many other nonlinear evolution equations.

The history of the concept and identification of Learning Disabilities (LD) has important stages of development which should be considered by the researchers of this field. This development includes different thoughts and experiments which are still controversial until recently. This paper discusses this development and divides it into four periods which consider different factors of each period such as: the location, scholars and critical perspectives and practices. Discussion about the impact of the history on the current period is provided.

This paper aims to show the closer link exists between the natural environment and economic development. It argues environment is a foundation for economic development. It is obvious that nature provides us with natural resources by which we humans can satisfy our desires. But, the problem is, humans go beyond a limit, and intervene in nature. The concentration of carbon dioxide has increased since the pre-industrial era primarily due to the combustion of fossil fuels and deforestation. Environmental degradation and environmental change have, therefore, threatened people’s health, physical security, material needs and social cohesion. Therefore, improper exploitation of natural resources and unlimited intervention in the natural environment jeopardizes the sustainability of any development.
