A Study on Barker Code of Radar Pulse Compression Technique

Range resolution is important performance parameter to distinguish a target accurately. The destination of modern radar systems, to overcome the limitations of existing analog radar systems, i s to improve the range resolution of the distance with low transmission power. For that reason, the research on pulse compression techniques is briskly studying. In the Receiver, modulation system of transmitted signal which has used in pulse compression technique is divided PM and FM to distinguish a target. In this paper, We analysed and designed the pulse compression signal pr ocessing module using the Baker Code which is the one of PM method's.
Experiments on a barotropic rotating shear layer. Part 1. Instability and steady vortices

The barotropic shear layer in a rotating fluid is studied in a laboratory experiment. Through the rotation of circular sections in the base and lid of a circular tank relative to a background rotation of the entire system, a vertical layer of strong horizontal shear develops, the Stewartson layer. Above a critical shear, the shear layer breaks up through barotropic instability, which is an inertial instability. The flow then develops a string of vortices along the shear zone. It will be shown that the transition from an axisymmetric flow to regular vortices occurs through a Hopf bifurcation. Subsequent transitions to more complex flows, such as modulated vortices, chaos and highly irregular flow, will be presented briefly, while the main points of this paper are the primary instability, steady vortices and their nonlinear dynamics. Among the issues discussed is the sensitivity of the flow to the direction of the differential shear. The experimental data will be used to test the ability of boundary layer theory and quasi-geostrophic theory to predict the onset of instability and the range of unstable wavenumbers.
Conspectus of the genera Amylotheca, Cyne, Decaisnina, Lampas, Lepeostegeres, and Loxanthera (Loranthaceae)

The Australasian/Malesian group of genera Amylotheca, Cyne, Decaisnina, Lampas, Lepeostegeres and Loxanthera is reviewed. Particular attention is given to the species of the Malesian region, as a precursor to a treatment of Loranthaceae for Flora Malesiana. The genera are part of a floristic element of Gondwanan derivation which has diversified in the southeast Asian and western Malesian region, and has reached the Papuasian/Australasian region from the west following the establishment of Charles’s Line. The six genera comprise 46 species ( Amylotheca 4, Cyne 6, Decaisnina 25, Lampas 1, Lepeostegeres 9, Loxanthera 1). Along with the Australian genus Lysiana (8 species) they form a natural group with tribal or subtribal status. Major centres of species richness are in Borneo, the Philippines, and New Guinea. Revised genus and species circumscriptions necessitate a number of nomenclatural changes to earlier regional treatments. Three species are described as new, viz., Cyne baetorta, C. monotrias and Decaisnina longipes. There are 15 new combinations, viz., Cyne papuana, C. perfoliata, Decaisnina aherniana, D. amplexicaulis, D. angustata, D. celebica, D. confertiflora, D. crassilimba, D. cumingii, D. miniata, D. ovatifolia, D. revoluta, D. sumbawensis, D. viridis, and D. zollingeri.
Gene control and remodeling during hematopoiesis

Marinus Heidemans onderzoek concentreerde zich op processen die plaatsvinden tijdens de ontwikkeling van bloedcellen en op de vraag hoe fouten tijdens deze processen kunnen leiden tot bloedcelkanker. Een belangrijk deel van zijn onderzoek richtte zich op de rol van de enzymen Hdac1 en Hdac2 tijdens bloedcelontwikkeling. Deze enzymen spelen een belangrijke rol bij de regulatie van bepaalde eiwitten in de cel. Ze kunnen een chemische groep, de acetylgroep, van die eiwitten afhalen. Hierdoor verandert de structuur van een eiwit, waardoor het anders gaat functioneren. Omdat er aanwijzingen zijn dat Hdac1 en Hdac2 een rol spelen bij het ontstaan van verschillende soorten bloedcelkanker is van groot belang om hun functies tijdens bloedcelontwikkeling nauwkeurig in kaart te brengen. Met behulp van genetisch gemodificeerde muizen, waarin Hdac1 en Hdac2 in bloedcellen kunnen worden uitgeschakeld, ontdekte Heideman dat de afwezigheid van Hdac1 en Hdac2 in T-cellen kan leiden tot het ontstaan van een lymfoom. Dit is een belangrijk gegeven, omdat HDAC-remmers tegenwoordig gebruikt worden als therapie tegen bloedcelkanker. Heideman laat zien dat verwijdering van Hdac1 en Hdac2 uit T-cellen, hetgeen vergelijkbaar is met het remmen van hun activiteit, juist leidt tot bloedcelkanker. Dit zou dus ook een bijwerking van HDAC-remmers kunnen zijn.
TOOLS TO DETECT, IDENTIFY AND MONITOR PHYTOPHTHORA SPECIES IN NATURAL ECOSYSTEMS

Phytophthora is a genus of plant pathogens responsible for severe damage to crops, natural vegetation and forestry worldwide. Accurate detection, diagnosis and species identification is fundamental to disease management, clear scientific communication and the statutory measures to prevent pathogen spread and yet this often proves challenging. Many serious disease problems have emerged in recent years, often associated with previously undescribed Phytophthora species and damaging plants in both commercial production systems and natural ecosystems. Many advances in DNA-based molecular diagnostics and DNA sequencing have been made recently that increased our ability to accurately detect and characterise Phytophthoras. However, there is a continual need for improvement and an increasing interest in a broader monitoring of Phytophthora species in natural ecosystems to get a better feel for their distribution and impact through understanding their ecology. This review examines the technical advances in the field and the rationale for such studies on Phytophthora.
Gingival Thickness: Critical Clinical Dimension of Periodontium

Clinical appearance of normal gingival tissue in part reflects the underlying structure of epithelium and lamina propria. It has been described that particular shape, topographical distribution, and width of gingival are clearly functions of presence and position of erupted teeth. Moreover, tooth shape seems to have an important impact on the clinical features of surrounding gingiva and probably also underlying tooth-supporting periodontal tissue. The thickness of masticatory mucosa was studied in a descriptive manner by conventional histology on cadaver jaws. Others assessed the mucosal thickness in edentulous patients using invasive method of injection needle, macroscopic measurement of histologic sections, a graduated periodontal probe or cephalometric radiographs. Noninvasive methods were performed with ultrasonic devices. A-mode ultrasonic device was used to measure tissue thickness in edentulous patients. B-mode was used to visualize soft and hard tissue relationships while also measuring soft tissue thickness. Among the various macroscopic features of gingiva, the gingival thickness (GT) is least discussed and not mentioned in the standard textbooks and journals. There are few terminologies which are not well defined in periodontal literature like periodontal phenotype, gingival phenotype, gingival architecture, gingival morphology, and GT; hence, this review article will put some light on these terminologies and literature review related to the clinical importance and relevance on masticatory mucosa thickness, chiefly on palatal mucosa and gingiva.
Effect of partial soil wetting on transpiration, vegetative growth and root system of young orange trees

The wetted area fraction is a factor critical to the success of drip irrigation. This study aimed to evaluate the effect of partial soil wetting on transpiration, vegetative growth and root system of young orange trees. The experiment was carried out in a greenhouse where plants were grown in 0.5 m3boxes internally divided into compartments. The wetting of 12 % of soil area was tested on two types of soil cultivated with ‘Valencia’ orange trees grafted onto Rangpur lime and ‘Swingle’ citrumelo rootstocks. Transpiration was determined in 40 plants. Water extraction and root density were evaluated in the compartments. Transpiration is reduced by restriction in wetted soil area, and such reduction is influenced by the number of days after the beginning of partial irrigation, atmospheric evaporative demand and plant phenological stage. Mean transpiration of plants with partial irrigation was equivalent to 84 % of the mean transpiration of plants with 100 % of wetted soil area in the period studied. However, after 156 days of imposing partial irrigation there was no difference in transpiration between treatments. Plant acclimation was caused by an increase in root concentration in the irrigated area. After a period of acclimation, if the entire root system is wetted, soil water extraction becomes proportional to the percentage of wetted area after a short period of time. Despite the reduction in transpiration, there was no difference between treatments with 12 % and 100 % of wetted soil area in terms of vegetative growth.
Identification of races in Eucalyptus globulus ssp globulus based on growth traits in Tasmania and geographic distribution

Canonical discriminant analysis of 432 open-pollinated families grouped into 46 collection localities covering the natural geographic range of Eucalyptus globulus ssp globulus was carried out on four year growth data from five trial sites in Northern Tasmania. Combining results from the analysis of growth responses with natural geographic boundaries and reported taxonomic groupings it was possible to identify 12 geographical races in the E. globulus ssp globulus base population. The three races from Victoria [(1) the Otway Ranges, (2) the Strzelecki Ranges and (3) South Gippsland], the (4) King Island, the (5) Furneaux Group, and (6) Central Western Tasmania races, showed relatively similar growth responses. Races from eastern Tasmania, [ (7) Northeastern Tasmania, (8) Eastern Tasmania, (9) Jericho, and (10) Southeastern Tasmania] were distinct from the previous large group. Two small races, (11) Port Davey and (12) Lighthouse, Wilson's Promontory had very slow growth. The trees at the Lighthouse locality had a distinct shrub-like habit. The classification of four localities (South West Lavers Hill, Clarke Island, Dover and Recherche Bay) was doubtful. The variation in growth response across environments among the different races suggest that appropriate genetic groupings (tentatively the 12 geographic races identified here) should be made prior to further genetic analysis of E. globulus ssp globulus breeding populations.
KEY DETERMINANTS OF LITHUANIA’S SOVEREIGN CREDIT RATING

The topic concerning the determinants affecting sovereign credit ratings of a country became extremely relevant after the recent economic turbulence which brought relentless downgrades, especially for Central and Eastern European (CEE) countries in their sovereign credit ratings. In the face of economic downturn around the world, causing the reduced availability of global capital flows and the appetite for risk, it becomes essential for the countries to secure the high market grade ratings in order to be able to issue foreign debt to ensure the solvency of the country’s finances and to pursue a sound economic growth. The aim of the study was to elucidate the key determinants of the Lithuanian sovereign rating during the financial turbulence of 2008 and to explain their importance and dynamics through external borrowing costs of the country.
Advanced closed loop visual navigation for micro aerial vehicles

Autonomous Micro Aerial Vehicles (MAVs), in particular small multi-rotor MAVs, have gained large popularity in the research community over the past couple of years. Due to their size, inherent safety and agility, MAVs are not only great research platforms, but have great potential in tomorrow’s civil and industrial tasks such as: search and rescue, surveillance and inspection. The control of MAVs during autonomous flights relies on the knowledge of variables, such as the position, velocity and orientation of the vehicle. However, these cannot be measured directly or drift-free by inertial sensors typically used onboard the MAVs, necessitating an additional position reference. While GPS is a popular choice for outdoor applications like aerial photography, it suffers from accuracy issues in cluttered environments, while it is entirely unavailable in indoor missions. Another popular choice in estimating the pose of a MAV with respect to its surroundings, is the use of laser-range finders, with many successful approaches existing in literature. The wealth of information captured, their low weight and high frame-rate make cameras a very attractive choice to feature the onboard sensor suite of a MAV. With this rationale, this dissertation focuses on enabling autonomous flights with MAVs in previously unknown indoor and outdoor areas, solely using an onboard camera as the only exteroceptive sensor. As vision cues alone are not enough to ensure robust flight performance, fusing cues from an Inertial Measurement Unit (IMU), available on every MAV, is key in enabling autonomous flights using solely onboard sensors. The complementary nature of visual and inertial data renders this setup a very powerful sensor combination, albeit posing challenges in their synchronization, calibration and more generally, their fusion within the estimation process. With the minimal and generic sensor setup of a single camera and an IMU on board a MAV, this dissertation investigates methods in the areas of control, state estimation, and finally path-planning, to form a novel, comprehensive framework for autonomous MAV navigation.
‘Partly self-made niches’? Student-only spaces in an LMS

Eighty-nine students were provided with a student-only live-voice space in a Learning Management System (LMS). Would they use it and, if so, would they feel sufficient ownership to create what Havnes (2008) described as “partly self-made niches”? In this study, a substantial proportion of respondents reported that they used the space not only for social support but also for key aspects of peer-learning. They reported that these student-only sessions gave them freedom to explore module-topics in new ways, and to share professional practice. Some disliked the lack of structure, but many valued the freedom to vary the focus and pace of their sessions. Several interviewees reported setting up sessions at short notice – for example, via Twitter – to meet their immediate concerns and requirements. A number of respondents valued these sessions as distinctive from, and complementary to, their tutorials in the same live-voice environment. The paper links these findings to debates about whether peer-learning should be explicitly organised, and about how education can disrupt itself as advocated by Bass (2012).

This process eliminated the constraints of shape and mechanical characteristics for implants.
GROWTH RESPONSE OF HAIR SHEEP FED UREA-AMMONIATED GUINEAGRASS (PANICUM MAXIMUM) HAY

Laboratory, digestion, and growth studies evaluated urea as a source of ammoniation for quality improvement in guineagrass (Panicum maximum) hay. Large round bales (320 kg) were reconstituted with water to yield a final moisture concentration of 25%, and treated with urea at 0, 4 or 6% of the forage DM. The urea solution was sprayed onto both flat surfaces of the bales. Each treatment was applied to three bales. Each bale was stored air-tight in individual 6-mil thickness plastic bags for 60 days. Crude protein concentration and in vitro organic matter digestion increased in a linear (P 0.10), however apparent fiber digestibilities increased in a linear (P < 0.05) manner due to urea treatment. Linear improvements in daily gain (P < 0.05) and gain/ feed (P = 0.07) were observed by urea treatment. Urea ammoniation offers potential for improving the feeding value of tropical forages, and provides an option for quality forage during the dry season.
A Techno-Economic Analysis of the Potential forSalinity Gradient Power Generation in the Gambia

As fresh river water flows into the sea, chemical potential energy is dissipated during the mixing process due to the large difference in salt concentration between these waters. It is possible to extract some of this chemical potential energy as useful work, offering the possibility of a reliable, local, renewable source of energy. The Gambia is a developing country on the coast of West Africa that is centered geographically, culturally, and historically on the Gambia River. Salinity gradient power using flow from the Gambia River could provide an attractive option as the Gambia looks to expand electricity generation capacity. A high-level technological and economic analysis of the production of electrical power using pressure retarded osmosis (PRO) was conducted to understand the short-term and longterm viability of this process for energy generation in the Gambia. Current membrane technology was modeled and a sensitivity analysis was carried out on key variables to determine the effects of possible future technological improvements. The short-term viability of this technology, both in the Gambia and in other regions around the world, is limited mainly by the current market landscape and the economics of the PRO process based on current membrane technology and prices. Membrane cost, membrane life, and water permeability are the key drivers that make the current technology more expensive than alternative energy sources. The long-term viability of PRO technology in the Gambia would also be limited by access to water with a sufficiently low salt concentration as saline water intrusion is significant in the Gambia River estuary.
The Simulation Experiments on Impulse Characteristics of Tower Grounding Devices in Layered Soil

Reducing the impulse grounding resistance of transmission line tower grounding system is the major measure to improve the lightning impulse withstand level and to ensure power system stability. For tower mainly adopts box with radiation grounding devices, this paper uses simulation experiments method based on similarity theory, researches the influence of radiation length, radiation angle and the proportion of box and radiation, branch length on the box with radiation grounding devices’ impulse characteristics in layer soil model. Results of the experiments show that the branches have an effective use of length, the box and radiation have an optimal proportion, over length radiation or improper proportion will render the resistance reduction ineffective. According to the results of the experiments, we have gotten the optimal length rays add branch and put forward an impulse characteristics features better tower grounding structure which is named T2-15-25&H2-15. There are some references for engineering.
Genetic approaches to dissect iron efficiency in maize

Sparse iron (Fe) availability, which frequently occurs in soils with alkaline pH, can lead to leaf chlorosis, a reduced Fe content in harvest products, and yield reduction in maize. The objectives of this study were (i) to describe patterns of sequence variation of 14 candidate genes for mobilization, uptake, and transport of Fe in maize, as well as regulatory function on these processes, (ii) to examine whether Fe-efficiency is an adaptive trait by determining if these genes were targets of selection during domestication, and (iii) to test if the allele distribution at these candidate genes is different for the different sub-populations of maize. The nucleotide diversity of Mtk was reduced by Benke and Stich 2011. Genome 54:674–683 13 78% in maize compared to teosinte. The results of our study revealed for the genes Naat1, Nas1, Nramp3, Mtk, and Ys1 a selective sweep, which suggests that these genes might be important for the fast adaptation of maize to new environments with different Fe availabilities.

Chelid turtles of the Australasian Archipelago: II. A new species of Chelodina from Roti Island, Indonesia

A new species of Chelodina (Testudines: Pleurodira: Chelidae) is described from Roti Island, west of Timor, East Nusa Tenggara Province, in the southeastern Indonesian Archipelago. The species is endemic to Roti, a small and relatively xeric island. It is most similar and most closely related to Chelodina phtchardi from Papua New Guinea and C. longicollis from Australia, less closely related to C. novaeguineae and C reimanni from New Guinea.
The Effect of HLA-DRB 1 allele Mismatch on the Results after Hematopoietic Stem Cell Transplantation

Abstract : Introduction. We evaluated the effect of HLA-DRB1 allele mismatch on the results of HSCT in patients with haematological malignancies. Patients and methods. We compared 43 patients with an HLA-DRB1 allele-mismatched (DRB1-MM) donor (5/6 match) with 86 patients with an HLA-A, -B, and -DRB1 matched unrelated donor (6/6 MUD). The effect of an additional HLA-C mismatch was also studied. The two groups were well matched for all major characteristics such as year of HSCT, age, disease, disease risk index (DRI), stem cell dose, and conditioning. Results. The 5-year overall survival was 52% and 62% (p=0.27), and relapse-free survival was 42% and 47% (p=0.18) in DRB1-MM and MUD patients, respectively. Non-relapse mortality at one year was 12% and 15%, respectively (p=0.55). The cumulative incidence of relapse at 5 years was 46% in DRB1-MM patients and 35% in MUD patients (p=0.03). However, additional HLA-C mismatch affected the result negatively in the DR-mismatch cohort but not in the MUD cohort. Conclusion. The results suggest that an isolated HLA-DRB1 allele mismatch is acceptable but that additional mismatches may be detrimental. DOI : Coming Soon
