A critical review of user fit-out in habitable rooms in high-rise residential apartments in Malaysia
No full textNowadays, high-rise residential apartments (HRRA) are developing very fast in major urban areas in Malaysia. However, the layouts of these apartment units seem to be too typical and lacking certain contextual socio-environmental considerations. A residential unit accommodates more than just rooms. There are distinct spaces with various Use-Territories (UTs) inside every room created by furniture layout. During the design stage, usually less importance is given to UTs. In search of their impact, the objectives of this study were firstly to identify the most popular furniture with their approximate dimensions, secondly to find their location in terms of distance from window, and thirdly, to identify typologies of furniture layouts in terms of UTs. Based on a questionnaire survey distributed among 98 HRRA residents in the city of Johor Bahru, the conceptual furnished plans of studied rooms were drawn. That was followed by a qualitative categorization carried out to extract the typologies of mostly-used UTs. Four typologies for living room and six of that for bedroom were identified through comparative analysis. The study showed that the social behavior of occupants in terms of arranging UT may be against their indoor environmental condition of daylighting. The significance of the study lies in the fact that in a tropical country like Malaysia with abundance of daylight but associated with glare, thermal heat gain, and low air movement, social needs can bend the users’ decisions to arrange pre-conceived convention of UTs in habitable rooms. Therefore, designing layouts or orienting habitable rooms should need more investigation
Implementation of the matrix differential transform method for obtaining an approximate solution of some nonlinear matrix evolution equations
Get PDFThis article introduces the matrix differential transform method (MDTM) to apply to matrix partial differential equations (MPDEs) and employs it for solving matrix Fisher equations, matrix Burgers equations and matrix KdV equations. We show how the MDTM applies to the linear part and nonlinear part of any MPDE and give various examples of MPDEs to illustrate the efficiency of the method. The results obtained are in excellent agreement with the exact solution and show that the proposed method is powerful, accurate, and easy
Sperm macromolecules associated with bull fertility
No full textBull fertility, ability of the sperm to fertilize and activate the egg that sustain embryo development, is vitally important for effective and efficient production of cattle. Fertility is a complex trait with low heritability. Despite recent advances in genomic selection and possibility of enormous paternal benefits to profitable cattle production, there exist no reliable tests for evaluating semen quality and predicting bull fertility. This review focuses on sperm macromolecules such as transcripts, proteins and the epigenome, i.e., the functional genome that are associated with bull fertility. Generating new information in these systems is important beyond agriculture because such progress advances the fundamental science of the mammalian male gamete while at the same time introduces biotechnology into livestock production. Sperm macromolecules and epigenome markers associated with bull fertility can be used alone or in combination with the current SNP microarrays to determine sperm quality and to indicate bull fertility
Functional aspects of seminal plasma and sperm proteins and their potential as molecular markers of fertility
No full textMolecular components of sperm and in the media surrounding them influence bull fertility. Given this concept, proteins of the seminal plasma modulate crucial functions and events of reproduction, such as sperm motility and capacitation, cell protection, acrosome reaction, fertilization and embryonic development. Sperm proteins are also important for successful fertilization, egg activation and embryo development. Empirical associations between seminal and sperm proteins and fertility in the bovine indicate that these proteins are potential molecular markers of the male reproductive status

Construction of Energy Preserving QMF
Get PDFRecently, a family of perfect reconstruction (PR) quadrature mirror filterbanks (QMF) with finite impulse response filters (FIR) from systems of biorthogonal refinable functions and wavelets were introduced and also applied to image processing. However, a detailed procedure was absent. The main objective of this paper is to present extensive examples that will provide a thorough process of construction of the new family of PR QMF with FIR filterbanks. These new filters are linearphase due to the symmetry property of their corresponding biorthogonal refinable functions and wavelets. In addition, these filters have odd lengths so that the symmetric extension can be easily applied. Another important feature is that the filters preserve energy (EP) very well. The notion of Condition EP was thus introduced for the purpose of further examining these features
Bianchi Type-I Hyperbolic Models with Perfect Fluid and Dark Energy in Bimetric Theory of Gravitation
Get PDFThree different Bianchi type-I cosmological models as related to perfect fluid, with quintessence and with Chaplygin gas, in bimetric theory of gravitation have been deduced. The perfect fluid model has hyperbolic geometry and all its physical parameters are also hyperbolic in nature and therefore they have been studied from hyperbolic geometric view point. All these models are isotropize and shear-less. Other geometrical and physical behaviors of the models have also been studied. The hyperbolic geometric view point of the models will be helpful to the people who use observational data to search for such type of geometry
LRS Bianchi Type-I Cosmology with Gamma Law EoS in f(R; T) Gravity
Get PDFWe have studied the locally rotationally symmetric (LRS) Bianchi type-I line element in f(R; T) (R is the Ricci scalar and T is the trace of the stress energy tensor) theory of gravity in presence of EoS parameter. The simplest case of f(R; T) gravity, i.e. first choice, is considered. The “gamma-law” equations of state are considered to explore the role of particle creation in the early universe. The exact solutions of the field equations are obtained using the scalar expansion proportional to the shear. The physical and kinematical properties of the model are studied
Impact of Permeable Lining of the Wall on the Peristaltic Flow of Herschel Bulkley Fluid
Get PDFThe peristaltic motion is modeled for the Herschel Bulkley fluid, considered to flow in a non-uniform inclined channel. The channel wall is supposed to be lined with a non-erodible porous material. The flow is considered to be moving in a wave frame of reference moving with same velocity as of the sinusoidal wave. Low Reynolds number and long wave length assumptions are made to solve the model. Analytical solution is obtained for the pressure difference and also for the frictional force. Graphs are plotted, using Mathematica software, for both the results of pressure difference and frictional force against time average velocity. We observe that increasing the porous thickening, increases the pressure difference while, it decreases the frictional force. It is seen that the behavior of the pressure difference is opposite to the behavior of the frictional force for all the parameters considered
