Vibration performance and energy harvesting potential of two in-situ stairs is evaluated using voltage output of an electromagnetic induction harvester prototype. First, the validation and benchmarking procedure is provided for a prototype electromagnetic induction harvester to assess 1) performance as a quantitative sensor for vibrations and 2) feasibility as a low-demand energy harvester. Secondly, the dynamic characteristics of two in-situ stairs are evaluated and compared to FEA and simplified analytical single-degree of freedom (SDOF) models.

In this paper we are trying to investigate the impact of public debt accumulation on the Egyptian public investment growth to ascertain the validity of crowding out theory. The research adopts Vector Error Correction Estimation techniques to determine the terrible nature of the relationship between public debt accumulation (both internal and external debt) and public investment growth in Egypt. We are using data covering the period 1981-2015 sourced from the Central Bank of Egypt and the World Bank data base.

Purpose: The current study was conducted to compare between the effects of cryolipolysis and liposuction in abdominal adiposity in females. Subjects and Methods: Thirty females suffering from localized fat deposits at the abdominal area were involved in the study. Their Body Mass Index(BMI) between 30 kg\m2 -34.9 kg\m2.Participants age was ranged from 30-40 years. They were classified randomly and equally into two groups Group I: This group was composed of fifteen female suffering from localized fat deposits at the abdominal area.

In recent years, organizations have come across complex databases due to the development of technology, the growth of databases and information technologies, and the use of widespread information technologies. If the data found in line with the needs of the institutions are managed successfully and effectively, it is obvious that the institutions and organizations will offer great advantages and opportunities in economic terms. Each action performed in the digital environment leaves a data record behind it.

The economic and social development of nations all over the world relay to a large extent on the quality of its road transportation system. Vast amounts of money have been invested and are still being invested in the construction of roads. Similarly, large amount of money is required to ensure that these roads having been constructed can continuously fulfill their function.

Bangladesh has already achieved the status of a developing country in the world recently. To achieve the status remittance played an important role undoubtedly. But, earning remittance has become a very challenging issue at present both in home country and abroad. Most of the expatriates and their family members told their sufferings and despairs regarding earning remittances substantially. They cannot fulfill their entire expectations by receiving remittances.

Background and Objective: Resisted Training and Natural Extract (green tea) for women with insulin resistance syndrome improved the level of TNF (α), lipid profile, exercise capacity, prevent cardiovascular complication and decrease morbidity. The effects of three months resisted training and natural extract on TNF (α) and lipid profile in women with insulin resistance syndrome were investigated in this study. Material and methods: Sixty insulin resistance syndrome untrained obese women with age of 40-50 years were included in the present study.

Over the past decades, the competition of household air conditioning products has become sharp in Taiwan. The life-cycle of a producthas reached its maturation. Moreover, as the global trend of micro-profits arrives, many brands including some famous and other ordinary ones have been created by enterprises.

Background: Shoulder disorder are common musculoskeletal disorders, one in every 5 persons experiences shoulder problems at some time in his / her life. It is a phenomena of mechanical compression of the rotator cuff against the anterior under surface of the acromion and caracoacromial ligament particularly during arm elevation. Objective: This study was conducted to investigate the effect of low level laser therapy versus acupuncture like TENS in chronic shoulder impingement syndrome on intensity of pain, joint ROM and Functional level of shoulder.

Background: Lysholm Knee Scale is a knee- is an instrument used to assess the results of rehabilitation from knee injuries, especially those requiring anterior cruciate ligament reconstruction. it measures recovery of knee joint function based on activities of daily living. Objective :The purpose of this study will be to test the face validity, the content validity, the feasibility, the internal consistency reliability and the test retest reliability of Arabic-language version of Lysholm knee scale to measure the PF level in knee osteoarthritic patients.
