In recent years, a raising problem encountered by high school students in general and rural ones in particular is extremely bad speaking skill. This leads to a serious subsequence is that quality of students is low as well as learning and teaching have to face to many difficulties due to the reason that speaking skill is an essential instrument when learning communication in any another language. The problems were related to speaking materials, students’ physical limits, and supporting equipment.

A study on species composition and density of polychaete (Polychaeta) was investigated in mangrove eco-system, Da Loc commune, Hau Loc District, Thanh Hoa province. Samples were collected in April, July, and November, 2010, from cross-sections of Len estuary and mangrove forests. A total of 15 polychaete species, belonging to 11 genera, 9 families and two groups of settlers (Sedentaria) and mobile (Errantia), were recorded in the study areas.

The physical and proximate analysis of the fuel used during cooking was determined. The properties viz., moisture content fixed carbon, volatile matter, ash content was determined and the physical properties like bulk densities, resistance to water penetration and the shatter resistance of agro residue briquettes were determined to know the suitability of fuel for cook stove.

The Denver test has been applied in community in Vietnam. But in Hue city, it was just used to assess and follow the psychomotor development for children with health problems, not in community. The objectives of study are to assess the physical, psychomotor development of infants in Hue City in 2009-2010 and to identify factors in the relation with physical, psychomotor development of infants.

The ripplon modes of two segregated Bose-Einstein condensates (BECs) confined by one and two hard walls are respectively studied by means of the hydrodynamic approach within the Gross-Pitaevskii (GP) theory. For the system at rest we find that due to the spatial restriction the dispersion relations are of the form ω ∼ k 2 in low momentum limit for both cases, while for the system in motion parallel to the interface the dispersion relations for both cases are ω ∼ k at low momentum limit and, furthermore, the system becomes unstable.

In traditional switched LANs, the physical topology is closely related to the logical topology. • Generally, workstations must be grouped by their physical proximity to a switch. • To communicate among LANs, each segment must have a separate port on the backbone device or a connection to a common backbone.

The human species' use of began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.

Although allostery plays a central role in driving protein–DNA interac-tions, the physical basis of such cooperative behavior remains poorly understood. In the present study, using isothermal titration calorimetry in conjunction with site-directed mutagenesis, we provide evidence that an intricate network of energetically-coupled residues within the basic regions of the Jun-Fos heterodimeric transcription factor accounts for its allosteric binding to DNA.

3D models are getting more and more attention from the research community. The application potential of 3D models is enormous, especially in creating virtual environments. In Vietnam National University - Hanoi, there is a need for a test-bed 3D environment for research in virtual reality and advance learning techniques. This need raises a very good motivation for the research of 3D reconstruction. In this paper, we present our work toward the creating of a 3D model of Vietnam National University - Hanoi automatically from image sequences.

The project uses a dual approach which focuses on both the physical / scientific dimension of aquaculture and the educational / training dimension of aquaculture extension program development. This dual approach enables the improvement of aquaculture practises resulting from Dimension 1 to be consolidated and disseminated more broadly through provincial aquaculture communities per medium of the activities of Dimension 2. The project supports capacity building in both aquaculture management and aquaculture extension (community education)....

This diagram illustrates the Physical layer (Layer 1) of the OSI model. The Physical layer is responsible for the ultimate transmission of data over network communications media. It operates with data in the form of bits that are sent from the Physical layer of the sending (source) device and received at the Physical layer of the destination device. Ethernet cabling, Token Ring network technology and SCSI all function at the Physical layer of the OSI model. Hubs and other repeaters are standard network devices that function at the Physical layer.

Female Sexual Dysfunction: Treatment General An open discussion with the patient is important as couples may need to be educated about normal anatomy and physiologic responses, including role of orgasm in sexual encounters. Physiologic changes associated with aging and/or disease should be explained. Couples may need to be reminded that clitoral stimulation rather than coital intromission may be more beneficial. Behavioral modification and nonpharmacologic therapies should be a first step. Patient and partner counseling may improve communication and relationship strains.
