The performance of the Dibrugarh University low latitude 3D theoretical model at different geomagnetic activity levels and for intense geomagnetic storms has been investigated. In this model the continuity, momentum and energy balance equations of ion and electron flux along geomagnetic field lines from the Northern to the Southern hemisphere are solved simultaneously. The model is used to simulate electron density at different geomagnetic activity conditions Ap=5, 10, 20.

This paper discusses the current process of eviction and resettlement of Khulna railway station remodeling project, and proposes proper compensation guidelines to ensure appellativewellbeing of the evicted slum dwellers and shopkeepers.Both legal and illegal land dwellers get resettled when a project requires land but there is no provision for compensation for illegal land dwellers in resettlement policies of Bangladesh.

In today’s World, Disciplines that are dealing with Project Management, can plan projects by using planning software based on Critical Path Method with an advanced scheduling & tracking engine. Day by day increase in R&D Projects and their complexity creates a need of single management software in our country. By using Planning Software, commencement & completion dates, resources to be used and their costs can be easily defined and tracked.

Orange fruits are acidic fruit which contain healthy nutritional content that works wonders for the body. It acts as a fabulous source of vitamin c and a wide variety of essential nutrients required by the body.

We show results from b-learning strategy used to teach volume concept in high school for several geometric figure. We applied a conceptual volume test (pretest) and we found that high percentage of students had several misconception and low knowledge about prism and pyramids. We work with a control group (traditional) and, experimental group (b-learning); this methodology includes conceptual activities and use of Khan academy tool. Population was 50 students divided in two similar groups; distinction gender was no made.

Considerando o processo de informatização das organizações e a exigência de que o serviço público se alinhe a esta realidade, surge a necessidade de analisar a importância do uso de ferramentas de apoio pelos gestores. A revisão da literatura ocupa posição introdutória no desenvolvimento de um projeto de conhecimento das produções científicas acumuladas sobre o tema.

The Northern coastal lakes in the Nile Delta of Egypt which have an ecosystem of distinctive nature is facing several problems which threaten, There are two main problems facing the coastal region of the delta, The first one is the erosion due to dynamic effects and reduction in sediment transport, the northern lakes connected to the Mediterranean Sea severely suffer from pollution due to dumping wastewater from agricultural, municipal as well as industrial origin into the lake. Hydrodynamic modeling is an essential tool to simulate the combined effect of these physical factors.

The goal of this work is to reveal factors which control Baoulé-Est gold occurrence. Gold traps which have been extracting from structural support have been tested by a variogram with the goal to find expect mineralized axis. Rocks with good grade and geochemistry anomalies have been inserted with the goal to find mineralized axis. Mineralized axis characteristics have led to elaborate mineralization hypothesis. Gold traps are plutonic nearbourgh quartz veins and N60°, N160°, NS faults zones junctions. N30° is the like trend of gold traps.

This research explores the basics of SDI, and investigates the National SDI of different countries. Further, the research analyses SDI implementation in developing country with specific reference to the National Geospatial Data Infrastructure (NGDI) of Nigeria. The research assesses the status and the milestones of NGDI implementation using key SDI components as assessment variables. These components were grouped into four classes: Policy and Legal Issues, Technical, Funding and People.

In this age of science and Technology, mathematics now dominates almost every field of one’s activities. It has permeated through the human life in such a way that, it has now become every man’s everyday concern. Elementary education grooms students to become competent in every aspects of life. India has made a significant investment in its education. Again RTE 2009 guarantees quality mathematics education at elementary level.
