Integrated Water Resources Management and Climate Change Adaptation Strategies

Water is an important and integral part of our ecological system. It is not only a vital source of life for human beings but it also supports agriculture, livestock, industries, and the environment. Declining per capita water availability, competing water demand for different uses and users, changing food habits and life styles, livelihoods and socioeconomic scenarios climate change and environmental needs call for holistic management of water resources. The planning, designing, development and management of water resources depend on its spatial and temporal variation. 

While doing so it is also important to consider natural, social, physical, financial and human capital as well as cultural, historical and geographical situations available in the country. Integrated Water Resources Management (IWRM) is basically a process of utilization of water resources in such a manner so that combined and coordinated resources utilization creates many times better cumulative impact both in terms of quality and quantity without adverse impact on other resources, than single resource utilization and combining the impact of all the water resources afterwards. It varies from place to place and no single solution fitting to all the situations can be developed.

Structures and Biosynthesis of Enediyne Natural Products

Natural products produced by many plants, bacteria and fungi as secondary metabolites have been the major drug source for pharmaceutical industry for the last several decades. Enediyne natural products discovered in 1980s are unique member among natural product family with potent DNA cleavage activity. A typical enediyne natural product is structurally characterized by a highly unsaturated enediyne core containing two acetylenic groups conjugated to a double bond in nine- or ten- membered carbocycle. Thus the enediyne natural products are conveniently categorized into two subfamilies, nine-membered enediynes and ten-membered enediynes.several examples of nine-membered enediynes (C-1027 from Streptomyces globisporus and neocarzinostatin from Streptomyces macromomyceticus) and ten-membered enediynes (calicheamicin from Micromonospora echinospora and esperamicin from Actinomadura verrucosopora.

Although total synthesis of almost all enediyne natural products has been achieved by organic synthesis, the blue print of their biosynthesis in cells is still not quite clear to us. Before discovery and sequencing of enediyne gene clusters, researchers speculated biosynthesis pathways of enediyne natural products by biomimetic synthesis and feeding of isotope labeled starting material to enediyne producing bacteria strains.

Enterprise Risk Management in Construction Companies: Recent Trend

Traditionally, risk management is segmented and conducted in separate business units or departments (i.e., silos) within a company. Under silo-based risk management, silos deal with their own risks, and none single group or person in the company has a grasp of the entire exposure that the company faces. This is attributed to the way people think about solving problems, the existing organizational structure, and the evolution of risk management practice. In addition, this is due to the fact that each silo within a company possesses the best expertise to address the risks within its area of responsibility.

In recent years, a paradigm shift has occurred in the way companies view risk management, and the trend has moved towards a holistic view of risk management. As the fundamental paradigm in this trend, enterprise risk management (ERM) has attracted much worldwide attention.

The Energy Effective Method of Modeling and Manufacturing of New Profile Teeth of Saw

Now in many countries are used old technology manufacturing ginning machines for ginning raw cotton. Also includes following operations. Punching of disks of necessary diameter 320 mm and an internal aperture 60 mm, transportation, cutting of teeth on teeth cutting machine, sharpening and training of working parts of a teeth of a saw is sharp sheet on press cutting machine. This operation is very time-consuming and demands very many time and labor and the big investment. As working hours saw gin disk in the working chamber are 72-80 h, it is important to check the increasing capacity of working saws. For this purpose it is necessary to improve properties of a saw and replacement of a material by stronger materials 

Results of research show the geometric characteristics of the saw and gasket of saw gin as well as define acceptable normal load for saw gin at different distances between the saw. In such cases, the strength and stability of saws are determined not only by its size but also on other complex geometrical characteristics with cross-section of saws and gasket.

Kaolin for Industrial Applications

Kaolin in Egypt is localities in 3 main areas, namely Sinai, Red Sea coast, and Aswan Kalabsha with a low grade ranging from 26% to 35% Al2O3 , accessory minerals, and varying degree of ferrugination and TiO2 are observed in different localities. Kaolins are exploited for a wide range of industrial applications,such as the production of paper, ceramics, plastics and paints. So, it has to be refined to meet commercial specifications out.

Clays are processed by mechanical methods, such as crushing, grinding, and screening, however, because clays are used in such awide range of applications, it is often necessary to use other mechanical and chemical processes, such as drying, calcining, bleaching, blunging, and extruding to prepare the material for use.

A Proposed Method on the Analysis of the Square Functionality: A Case Study: Beyazit Square Field Work

Technological developments and industrialism after the industrial revolution has caused migrations from rural areas to urban areas and as such has caused fast urbanization which has led to unplanned development of cities. People have started to use motor vehicles to reach far distances in thecities which have changed form and scale by spreading their boundaries. Especially after the II World War, as the motored vehicles have become the dominant form of transportation, the road surfaces in cities have increased and in inverse proportion to this, available areas for pedestrians have decreased.

One of the biggest urbanization problems that we are faced with today includes not taking into account the usage of the city areas by the pedestrians. Especially the traffic problem that reaches greater heightsin metropolitan cities and the fact that pedestrians are not able to find any place on the roads for themselves has made it mandatory to take new planning decisions relate to transportation in our era.

Concept of Finite Element Modelling for Trusses and Beams Using Abaqus

Abaqus is one of the powerful engineering software programs which are based on the finite element method. The Abaqus can solve wide range of problems from linear to nonlinear analyses. Abaqus is widely used in many sectors like automotive and mechanical industries for design and development of FEM products. The finite element method is a numerical technique for finding approximate solutions for differential and integral equations.

The finite element word was coined by Clough in 1960. In 1960s, engineers used the method for solving the problems in stress analysis, strain analysis, heat and fluid transfer, and other region. Abaqus CAE can provide a simple creating model, submitting the modal, monitoring, and evaluating result and then can also compare with theoretical calculation. In this report all the steps will be explained in different areas such as sketch a modal, assigning material property, applying boundary condition and loads, submit and monitor the job and view the deformed models using the visualization and create report for results. 

Delivering Medical Products to Quarantined Regions Using Unmanned Aerial Vehicles

Unmanned Aerial Vehicles (UAVs) are aerial vehicles or drones that operate without a human operator on-board. They are either controlled through radio frequency from a remote control or through a computer program installed on a computer on-board the drone. Initially used primarily by the military sector (e.g. for missile deployment during war), applications of UAV have extended to the civilian sector. Some of the current applications for UAV include: agriculture surveying, wildlife monitoring and conservation, real estate assessments, surveillance, meteorological studies, such as taking geographical samples at extreme heights, and courier services, such as Amazon CEO Jeff Bezo’s announcement in 2013 that the company would use drones for package delivery. 

Advances in technology and decreasing costs have led to an increased use of unmanned aerial vehicles (UAVs) by the military and civilian sectors. The use of UAVs in commerce is restricted by US Federal Aviation Administration (FAA) regulations. The FAA continues to demand that drones be controlled by a humanpilot and stay within that pilot’s sight line. These regulations forestall implementation of a large-scale drone delivery fleet. The FAA also has established a no-fly zone, which lies between 400 and 500 vertical feet, to ensure that drones remain distinct on radar from human-piloted aircraft. However, such restrictions do not necessarily apply to other countries. In fact, 57 countries and 270 companies were producing UAVs in 2013
