Measurments of Correlated Pair Momentum Distributions in 3He(e,e\u27pp)n With CLAS

We have measured the 3He(e,e\u27pp)n reaction at 2.2 and 4.4 GeV over a wide kinematic range. The kinetic energy distribution for ’fast’ nucleons (p \u3e 250 MeV/c) peaks where two nucleons each have 20% or less and the third or ‘leading’ nucleon carries most of the transferred energy. These fast nucleon pairs (both pp and pn) are back-to-back and carry very little momentum along q, indicating that they are spectators. Experimental and theoretical evidence indicates that we have measured N N correlations in 3He(e,e\u27pp)n by striking the third nucleon and detecting the spectator correlated pair

Two nucleon momentum distributions mea sured in 3He(e; e0pp)n

We have measured the 3He(e,e′pp)n reaction at 2.2 GeV over a wide kinematic range. The kinetic energy distribution for “fast” nucleons (p\u3e250   MeV/c) peaks where two nucleons each have 20% or less, and the third nucleon has most of the transferred energy. These fast pp and pn pairs are back to back with little momentum along the three-momentum transfer, indicating that they are spectators. Calculations by Sargsian and by Laget also indicate that we have measured distorted two-nucleon momentum distributions by striking one nucleon and detecting the spectator correlated pair

Complex Permittivity Determination from Measured Scattering Parameters of TEM Waveguides

This paper addresses the deembedding of the propagation function of waveguides from the scattering responses of setups composed of TEM waveguides terminated by launchers that introduce generic discontinuities. The de-embedding is aimed at estimating the permittivity of dielectric samples from the scattering responses of waveguides including the samples. The de-embedding is based on the double-delay method, that is applied to setups involving different launchers

Water related environmental issues in central asia

This article addresses the need for a sustainable water resource management in the Central Asian region with a hot, dry and continental climate. This research and its results meet sustainable development’s goals and also specifically the potential to solve or softening consequences of the Aral Sea ecological disaster. The urgency of this concern is felt most deeply in areas lacking potable water, most notably the larger Aral Sea region. During the long summer (from May until October) water consumption increases sharply and water sources cannot meet the demand. Intensive water use and sharply increasing of the water demand misbalances water flow in the main rivers as Syr Darya and Amu Darya which feed the Aral Sea. The primary challenge facing water supply and sustainability specialists in Central Asia and specifically in Uzbekistan is to balance competing water supply demand and water sources preservation in the region. Among these demands is the urgency of halting further depletion of water in the Aral Sea, and, ideally, to augment the water in that basin. But there is also the need to develop high quality water delivery systems for human and industrial use. And, of course, there is the question of what water can be left for the agricultural sector of the dry and hot temperature region to irrigate its crops or just sustainable water resources management. This study will address water-related issues in the Central Asian Republics with special emphasis on the Republic of Tajikistan. The authors analyse a current situation and describe the factors that contribute to these issues and will provide recommendations for alleviating the Aral Sea disaster. Authors offer to solve this problem with wider team from different fields

Relationship between Structure and Rheology of Hydrogels for Various Applications

Hydrogels have gained a lot of attention with their widespread use in different industrial applications. The versatility in the synthesis and the nature of the precursor reactants allow for a varying range of hydrogels with different mechanical and rheological properties. Understanding of the rheological behavior and the relationship between the chemical structure and the resulting properties is crucial, and is the focus of this review. Specifically, we include detailed discussion on the correlation between the rheological characteristics of hydrogels and their possible applications. Different rheological tests such as time, temperature and frequency sweep, among others, are described and the results of those tests are reported. The most prevalent applications of hydrogels are also discussed.</p
