The first humans （hominids） appeared at about the same geological time in three independent areas： in East Africa, southern Indochina and in the Kazakh steppe. People inhabiting all continents and countries around the world descended from hominids that emerged in these three foci then resided elsewhere. The number of people emerged 2-3 million years ago now about 7.0 billion people. They inhabit the planet and the master space. Kazakh steppe, located in the middle of the Eurasian continent, has always had a positive impact on neighboring countries. According to historical geological data obtained in the south near the ridge Karatau, the first people emerged on the territory of Kazakhstan were found about 2 million years ago. Such a conclusion was made on the basis of residual cultural pebble tools of hominids, founded by scientists. As a result of geological survey work carried out in the 1960＇s there were found some primitive people, starting with the era of＂Arystandy culture＂ and including the Late Paleolithic era in the area of ridges big and Small Karatau. There had been found the fossil remains of large mammals hunted by hominids around the sites of ancient people. Thanks for these residues the corresponding time of residence of primitive people can be judged from the animal world of the Kazakh steppe.

This work considers the problems of numerical simulation of non-linear surface gravity waves transformation under shallow bay conditions. The discrete model is built from non-linear shallow-water equations. Are resulted boundary and initial conditions. The method of splitting into physical processes receives system from three equations. Then we define the approximation order and investigate stability conditions of the discrete model. The sweep method was used to calculate the system of equations. This work presents surface gravity wave profiles for different propagation phases.

"Teacher, what are we going to do next class?" This is an exciting question which I often hear from my students. As an English conversation teacher, I can make the learning of English either a dull and boring duty, or an exciting adventure. It is very important that I make my students hate missing my class, and keep them guessing just what will happen the next time! Let us consider some important ways that any teacher can help his other students want to do

A new precision peak detector/full-wave rectifier of input sinusoidal signals, based on usage of dual-output current conveyors, is presented in this paper. The circuit gives a DC output voltage that is the peak input voltage over a wide frequency range, with a very low ripple voltage and low harmonic distortion. The proposed circuits use an all-pass filter as a 90° phase shifter of the processed input signal. To verify the theoretical analysis, the circuit SPICE simulations results have also been included, showing good agreement with the theory. Inherently, the circuit is well suited for IC implementation.

The biopharma industry is enduring sweeping change in response to the financial crisis, but one aspect of the in-dustry that emerged relatively unscathed and that perhaps has directly benefited from the crisis is new revolutionary innova- tion solution. Identifying opportunities in the next wave of technologies for biopharma, along with other policy initia- tives including financial crisis actions and climate policy, will affect on manufacturing biopharmaceutical products today and in the future in cost effective manner, and will be our adequate answer addressing to global geopolitical, economic and climate changes. It also underscores the search for new approach, evidenced by trends around new for- mulations to serve lower income patients. Microalgae biomass comes in many strains, and can be used by means of variety product developments. In the last years the key task of our R & D was to find a solution for these tasks. The bio- fuel market development dynamics include significant opportunity of microalgae raw material and microalgae proc- essing biomass rest of biodiesel manufacturing for biopharma global growth in cost effective manner. Second new source of microalgae raw material for biopharma include microalgae production through waste and wastewater cleaning. This should provide the opportunity to see the future in a new vision, where technology can serve as a revela- tion of the truth and where every endeavor is governed by reflection on and appreciation of the environment and thus leading to resolution of global tasks facing the world community and inclusion of microalgae in production and bio cycles open new cost effective ways for biopharma companies and conservation of nature. A truly coherent microalgae raw material and biopharma production policy has to find ways to bring these two traces closer for cost effective manufacturing, well being biopharma economy and human health.

It was discovered several decades ago that the natural geo-environment could substantially impact on the health of animals and humans. However, despite the growth of evidence supporting this discovery, there has not been a close interaction between geoscientists and health scientists in assessing the need to study the various facets of the relationships between human and animal health and air, water, soils and rocks. This book is timely in closing that gap as stated in its title.

bcrlin has become a home base to an array of international artists, writers, and filmmakers--and the Chinese arc no exception. From berlin University of the Arts graduate Shen Han, the genre? bending visual artist Xiao'er Liu, to documentary filmmaker and LGbT activist Fan Popo, incrcasing numbers of creative Chinese are drawn to the cosmopolitan city by its affordable (though rising) rents and infamous permissiveness.

Au has been loaded （1% wt.） on different commercial oxide supports （CuO, La2O3, Y2O3, NiO） by three different methods： double impregnation （DIM）, liquid-phase reductive deposition （LPRD）, and ultrasonication （US）. Samples were characterised by N2 adsorption at -196℃, high-resolution transmission electron microscopy, selected area electron diffraction, energy dispersive X-ray spectrometry, high-angle annular dark-field imaging （Z-contrast）, X-ray diffraction, and temperature programmed reduction. CO oxidation was used as a test reaction to compare the catalytic activities. The best results were obtained with Au loaded by DIM on the NiO support, with an activity of 7.2 × 10^（-4） molco·gAu^（-1）·s^（-1） at room temperature. This is most likely related to the Au nanoparticle size being the smallest in this catalyst （average 4.8 nm）, since it is well known that gold particle size determines the catalytic activity. Other samples, having larger Au particle sizes （in the 2-12 nm range, with average sizes ranging from 4.8 to 6.8 nm）, showed lower activities. Nevertheless, all samples prepared by DIM had activities （from 1.1 × 10^（-4） to 7.2 × 10^（-4） molco·gAu^（-1）·S^（-1）, at room temperature） above those reported in the literature for gold on similar oxide supports. Therefore, this method gives better results than the most usual methods of deposition-precipitation or co-precipitation.
