От Милы ушел супруг. И кто бы мог подумать, что на ее сторону встанет… свекровь! И не только встанет, но и проживать невестка с матерью мужа будут вместе! Этот необычный, редкий для всех времен тандем обусловлен и чувством вины за непутевого Арсения, и заботой о внучке, девочке одаренной и необычной. Но выдержит ли материнское сердце сыновний бунт? Сможет ли свекровь смириться, что рядом с Милой рано или поздно окажется другой мужчина?

ZP-NZP OFDM

ZP-NZP OFDM

Автор: Raza Ali Shah,Poompat Saengudomlert and R. M. A. Premanandana Rajatheva

OFDM has been an attractive choice for digital modulation in the recent years due to its robustness to channel fading and invulnerability to intersymbol interference. However, to achieve an optimal performance the corresponding channel estimation scheme need to be accurate. This book focuses on the use of guard intervals between successive OFDM symbols for channel estimation. A hybrid of blind and semi-blind estimation techniques is proposed to create an energy efficient scheme that can maintain accurate channel estimation as well as a low transmission BER. Multipath fading channel are considered for performance evaluation. The proposed hybrid scheme is tested in static as well as time varying channel environments using computer simulations. Simulation results show that the proposed scheme outperforms the existing schemes on the basis of BER performance for the same SNR.

Availability and Marketing of Fishes in Mymensingh, Bangladesh

Availability and Marketing of Fishes in Mymensingh, Bangladesh

Автор: Anisul Islam Mahmud and Kohinoor Afroz Rini

In the present study fish marketing systems in different markets of Mymensingh town, market price, consumers perceptions and fish sellers livelihoods were studied for a period of six months from July to December 2007. Data were collected through questionnaire interviews and focus group discussions. The market chain from producers to consumers passes through a number of intermediaries. Based on a sample of 60 retailers from the three different markets, the daily supply of fish were estimated as 5-6, 2-3 and 1-2 tonnes respectively. Most of the fishes (85%) have been transported from the rural areas of the district and the remaining part from external sources (15%). It is estimated that 48% of fish supplied in the markets were carps, 8% hilsa, 13% catfish, 7% small indigenous fish, 4.33% Thai koi, 3.66% prawns and shrimps, 6% tilapia, and 10% others including marine fish. The price of fish depends on market structure, species quality, size and weight. It was found that the price…

An Introduction to Chemistry of Trace Gases over Kannur,India

An Introduction to Chemistry of Trace Gases over Kannur,India

Автор: T. Nishanth and M. K. Satheesh Kumar

This book describes the continuous observation of prominent trace gases O3, and its precursors like NO, NO2, NOx, CH4 and Total NMHCs that significantly influence the air quality over Kannur, a coastal region in South India. Ozone being a prominent greenhouse gas, it plays a vital role in modifying the chemistry of the atmosphere by which it induces climate changes. Further, this highlights abrupt variations of O3, and NOx in the context of varying meteorological parameters during the annular solar eclipse on 15th January 2010. Likewise, air pollution formed out of the coordinated fireworks episode during festival seasons at Kannur is extensively discussed. The classification of hazardous organic emission during intense nighttime fireworks throws light on the nighttime chemistrythat influences the dynamics of the atmosphere.

Парки и сады

Автор: Андре Лефевр

Книга Андре Лефевра «Парки и сады», предлагаемая в серии «Классика садово-паркового искусства», была впервые переведена на русский язык и издана в Санкт-Петербурге в 1871 г. Современному читателю эта книга остается почти неизвестной, хотя она представляет собой один из интереснейших трудов по истории садово-паркового искусства. Написанная в жанре путешествия по разным странам, регионам и эпохам, книга отличается удивительной широтой охвата материала. Автор увлекательно рассказывает о древних садах Вавилона и Рима, о средневековых садах Испании и Персии, лучших европейских садах и парках эпохи Возрождения, садах Европы Нового времени. Отдельная глава посвящена садам и паркам России. А.Лефевр делится с читателем тонкими наблюдениями, подмечая характерные особенности национальных стилей садово-паркового искусства. Книга адресована как специалистам в области ландшафтного дизайна, так и всем тем, кто интересуется историей отечественного и зарубежного садоводства.

Numerical modeling of bedform development in turbulent flows

Numerical modeling of bedform development in turbulent flows

Автор: Quoc Y. Nguyen and John C. Wells

Development of river bedform under interactions with water flows is a complex process due to turbulence of the flow and continuous change of bed geometry. In this study, the problem was examined by numerical computations. Two latest advanced tools of Computational Fluid Mechanics, namely Large-Eddy-Simulation and Immersed-Boundary-Method, were employed. Flows were turbulent at low Reynolds number and treated in three-dimensions. Bed surfaces was treated as continuos medium rather than individual sediment particles. The results showed strong correlations between change of the bed surface and the shear tress applied by the flows. Development of bedform from initially flat bed to full-size sandwaves had been observed from the computations. Experimentally observed phenomena, such as development of ripple train, was also successfully reproduced.
