Research on the Influence of Material Permeability to Landslide Dam Seepage Stability

Landslide dams, often formed by quick deposits of landslide materials, are lack of sufficient consolidation, and loose in dam structure and material composition. Lacking of seepage control and flood drainage facilities, big water head difference can trigger seepage deformation of soil and influence landslide dam stability with the rise of landslide lake water level, which may lead to dam breach. The paper reports the experimental study on the seepage characteristics of landslide dam material, which takes the differences of grain grading into consideration. It was observed that piping and soil flow are the two seepage failure modes of landslide dam material. The experiments showed seepage deformation mode and permeability coefficient mainly depend on the condition of fine particles filling the pores between the coarse particle and the compactness. The paper provides a kind of critical hydraulic gradient equation of piping, which can be used in the critical hydraulic gradient calculation of the landslide dam materials with different densities.
Welfare Reforms and Consumption among Single Mother Households: Evidence from Canadian Provinces

This paper evaluates the impact of the 1995-1998 Ontario welfare reforms on the consumption among single mothers. Because welfare is a provincial responsibility in Canada, this study is able to consider the effects of the welfare reforms in Ontario, in comparison with other Canadian jurisdictions at the same time. By utilizing a difference in difference design I compare the changes in the consumption levels among Ontario single mothers to changes in the consumption levels among three distinct segments of Canadian population. The comparison with demographically identical groups under different provincial administrations and the implementation of difference in difference propensity score matching estimates sets my approach apart from previous similar work. The results indicate an initial decrease in the relative consumption levels among Ontario single mothers. This negative policy impact is not present in the long-term results.
Inhibitors of the TGF-β Superfamily and their Clinical Applications

The transforming growth factor-beta (TGF-beta) superfamily includes TGF-betas, activin, myostatin and bone morphogenetic proteins. Misregulation of the activity of TGF-beta family members is involved in pathogenesis of cancer, muscular dystrophy, obesity and bone and tooth remodeling. Natural inhibitors for the TGF-beta superfamily regulate fine-tuning of activity of TGF-beta family in vivo. In addition to natural inhibitors for the TGF-beta family, soluble forms of receptors for the TGF-beta family, blocking monoclonal antibodies and small chemical TGF-beta inhibitors have been developed. In this review, we summarize recent advances in our understanding of inhibitors for the TGF-beta superfamily and their medical applications.
Detection of fecal coronavirus antigen in diarrheic calves of high- and average-producing Holstein dairy cows

From January to December 2009, 661 fecal samples from natural cases of diarrheic calves were taken by veterinary staff from the Department of Large Animal Internal Medicine of Shiraz Veterinary School and veterinary practitioners in Fars Province, Iran. The samples were taken from 267 diarrheic calves of high-producing dairy cows (HPDCs) and 394 diarrheic calves of average-producing Holstein dairy cows (APDCs). Fecal samples were collected and submitted for the laboratory diagnosis of coronavirus antigens. Herd selection was based on geographical location and density of cattle in the region. All herds had HPDC and APDC coronavirus-infected diarrheic calves in their population. The rate of coronavirus infection in diarrheic APDC calves in the northern region was highest when compared to other geographical locations. It was also found that diarrheic coronavirus-infected HPDC calves in the northern region of Fars Province were at much lower risk of diarrhea than APDC calves in the same region (P 2 to 3 years) showed a higher rate of infection when compared to diarrheic HPDC coronavirus-infected calves in the same age group (P < 0.05). It was also found that the proportion of infected coronavirus diarrheic APDC calves decreased with the increased parity of their dams. There was no difference among the occurrence of coronavirus infection in diarrheic HPDC and APDC calves of different herd size groups.
On the similarity state transformation for Linear Parameter-Varying systems

Similarity state transformations between equivalent State-Space (SS) representations of discrete-time Linear Parameter-Varying (LPV) systems are investigated. Based on previous results, it is known that to characterize all equivalent LPV-SS representations, the state-transformation matrix must depend dynamically on the scheduling variable. However, preserving static dependence of a LPV-SS representation, i.e. characterizing all equivalent SS representation with static dependence, has primary importance both in control and identification. Therefore, first, the state transformation problem is investigated from an algebraic (behavior) point of view, then conditions are developed to guarantee preservation of the static dependence in similarity state transformations. Additional geometric interpretation of the obtained results, together with computational approach to synthesize state-transformations are also developed. An illustrative example is provided to demonstrate the validity of the obtained results.
Marine derived fungi of peninsular Malaysia - A biochemical perspective

In an effort to tap into natural products harboured by marine derived fungi in Malaysia, selected marine derived endophytic and manglicolous fungi from the coastlines of Peninsular Malaysia were investigated for their antibacterial potential. Forty-one strains were isolated from marine associated plants, comprised and comprised 12 and 19 endophytic strains from Vitex rotundifolia and Ipomoea pes-caprae respectively, while 10 manglicolous strains were from decaying mangrove wood collected in Peninsular Malaysia. In preliminary experiments, a plug assay was employed to study the antibacterial activities of all 41 fungi isolates. Fifteen of the endophytic isolates and nine of the manglicolous isolates displayed antibacterial activities against at least one of the test bacteria. Based on the plug assay, the endophytic fungi from Ipomoea pes-caprae were shown to display higher antibacterial potential in comparison to the endophytic fungi from Vitex rotundifolia. In particular, Minimidochium sp. and Bipolaris sp. (ISB0014) displayed antibacterial activities against 5 or more test bacteria. Potential fungi isolates with good antibacterial activities were further analysed through a broth microdilution assay. Minimidochium sp. and Dyfrolomyces rhizophorae exhibited promising antibacterial activities with minimum inhibitory concentrations not higher than 0.5 mg/ml. Bioactivityguided fractionation of D. rhizophorae extracts resulted in the isolation of fatty acids, palmitic and linoleic acid. Though ubiquitous in nature, linoleic acid is known as an essential health supplement and both fatty acids are used as biodiesel replacing conventional fuels.
Using coronal seismology to estimate the magnetic field strength in a realistic coronal model

Aims. Coronal seismology is used extensively to estimate properties of the corona, e.g. the coronal magnetic field strength is derived from oscillations observed in coronal loops. We present a three-dimensional coronal simulation, including a realistic energy balance in which we observe oscillations of a loop in synthesised coronal emission. We use these results to test the inversions based on coronal seismology. Methods. From the simulation of the corona above an active region, we synthesise extreme ultraviolet emission from the model corona. From this, we derive maps of line intensity and Doppler shift providing synthetic data in the same format as obtained from observations. We fit the (Doppler) oscillation of the loop in the same fashion as done for observations to derive the oscillation period and damping time. Results. The loop oscillation seen in our model is similar to imaging and spectroscopic observations of the Sun. The velocity disturbance of the kink oscillation shows an oscillation period of 52.5 s and a damping time of 125 s, which are both consistent with the ranges of periods and damping times found in observations. Using standard coronal seismology techniques, we find an average magnetic field strength of Bkink = 79 G for our loop in the simulation, while in the loop the field strength drops from roughly 300 G at the coronal base to 50 G at the apex. Using the data from our simulation, we can infer what the average magnetic field derived from coronal seismology actually means. It is close to the magnetic field strength in a constant cross-section flux tube, which would give the same wave travel time through the loop. Conclusions. Our model produced a realistic looking loop-dominated corona, and provides realistic information on the oscillation properties that can be used to calibrate and better understand the result from coronal seismology.
Effects of Glucocorticoid on Bone Metabolism Markers and Bone Mineral Density in Rats.

Statement of Problem: Glucocorticoid-induced osteoporosis is characterized by a decrease in osteoblast numbers and a marked impairment of new bone formation. Purpose: The ain of present study was to evaluate the effect of methylprednisolone acetate on bone metabolism and bone mineral density in rats. Materials and Methods: Eighteen male Sprague Dawley rats (8 weeks old, weighting 180 gm) were randomly divided into three groups: Group A (n=6), was a baseline control consisting of normal animals. Group B (n=6), was treated only by normal saline injection (0.9%) and group C (n=6), injected Methylprednisolone acetate (0.2 mg/kg/s.c. 3 times/week for 4 weeks). Changes in biochemical agents of serum calcium were evaluated by measuring acid phosphatase and osteocalcin, before and after treatment. Bone mineral density (BMD) of the lumbar vertebrae was also measured by dual energy x-ray absorptiometry (DEXA). Results: The results showed that, serum calcium levels were not affected by methylprednisolone acetate (p>0.05), but acid phosphatase levels of serum increased significantly (p≤0.05). In addition, the serum osteocalcin levels and bone mineral density of lumbar vertebrae decreased significantly (p≤0.05) in the methylprednisolone acetate-treated group as compared to the other groups. Conclusions: The findings indicate that administration of methylprednisolone acetate decreases bone formation and increases bone resorption in the lumbar vertebrae.
Mental Health Status is Subjective and is Revealed in ADHD Distribution

Mental health status is both subjective and objective. Computer intelligence should not be applied to determining this mental health status if artificial intelligence data has been obtained mainly from non-professionals in the field of mental health. Details of neuron biology and their changes are beyond the scope of computer scientists, and so merely mapping areas of the brain via functional Magnetic Resonance Imaging (fMRI) under various conditions, for instance, cannot provide the full scientific picture of the state of the brain. In addition, it is reasoned that the number of persons declared mentally unhealthy in any particular community is a reflection of the cultural norms of the local community.
In Vitro Re Generation and Marker Assisted Evaluation of Genetic Fidelity In Endangered Tree Species Moringa Peregrina (Forsk) Fiori

Moringa peregrina is a native plant in the United Arab Emirates; it is called “Shua”. It is an endangered species with important nutritive and medicinal properties. It shows high adaptability to the arid condition with short germination time after irrigation. Unmanaged grazing and slow regeneration rate after browsing leads to the endangerment of the species causing erosion in biodiversity. One way to protect these rare species is by multiplying the planting material through tissue culture system and re-introducing at the habitat. Microproagation is an in vitro method used for plant clonal multiplication under controlled condition. This technique allows conserving the genetic characteristics of the plants which are usually affected by environmental restrictions. In the present study different parts of M. peregrina explants will be used for standardizing the mass propagation. Direct organogenesis of nodal explants collected from the in vitro germinated seedlings were inoculated in MS media supplemented with different hormone treatment (TDZ, BA and NAA) with several concentrations. Thidiazuron treatment in the media observed to be better than BA and NAA combinations. It has been observed that media supplemented with TDZ 1 μM induced an average of 2.4 axillary shoots per explant. For callusing the results show that MS media supplemented with 2,4-D 2 μM/l and TDZ 0.5 μM/l found to have the highest callusing percentage and size. The rooting of in vitro developed plantlets obtained from nodal ex plants were induced through media supplemented with BA in combination with NAA and IBA. The number of roots was high in BA and NAA medium compare to BA and IBA. The genetic fidelity of the clones produced from

Recent Developments in Reconfigurable and Multiband Antenna Technology

A comparative analysis of various reconfigurable andmultiband antenna concepts is presented. In order to satisfy the requirements for the advanced systems used in modern wireless and radar applications, different multiband and reconfigurable antennas have been proposed and investigated in the past years. In this paper, these design concepts have been classified into three basic approaches: tunable/switchable antenna integration with radio-frequency switching devices, wideband or multiband antenna integration with tunable filters, and array architectures with the same aperture utilized for different operational modes. Examples of each design approach are discussed along with their inherent benefits and challenges.
Does linking farmers to markets work? Evidence from the World Food Programme’s Purchase for Progress satellite collection points initiative in Uganda

Using a non-experimental cross-sectional dataset of 471 households, we evaluate the impacts of satellite collection points (SCPs) under the Purchase for Progress (P4P) initiative implemented by the World Food Programme (WFP) on storage decisions and crop income from maize sales among smallholder farmers in Uganda. We find strong evidence that storage users had significantly more maize sales due to significantly larger inventories and received higher maize prices than the nonstorage users. This evidence is robust across the two econometric estimators, consisting of the ordinary least squares (OLS) and two-stage instrumental variable approaches. These results demonstrate that the SCPs are successful in linking farmers to markets and result in improved welfare of the users, suggesting that they should be scaled up and scaled out as a poverty-reducing development intervention and strategy in rural areas with storable agricultural products.
Optimal Matching for Observational Studies

Abstract Matching is a common method of adjustment in observational studies. Currently, matched samples are constructed using greedy heuristics (or “stepwise” procedures) that produce, in general, suboptimal matchings. With respect to a particular criterion, a matched sample is suboptimal if it could be improved by changing the controls assigned to specific treated units, that is, if it could be improved with the data at hand. Here, optimal matched samples are obtained using network flow theory. In addition to providing optimal matched-pair samples, this approach yields optimal constructions for several statistical matching problems that have not been studied previously, including the construction of matched samples with multiple controls, with a variable number of controls, and the construction of balanced matched samples that combine features of pair matching and frequency matching. Computational efficiency is discussed. Extensive use is made of ideas from two essentially disjoint literatures, namely st.
Gelatinisation Properties of Cassava Starch in the Presence of Salts, Acids and Oxidising Agents

The effect of various cations, anions, acids and oxidising agents on the gelatinisation properties of cassava starch was studied and wide variation was observed in the pasting and swelling properties. Sodium chloride and sodium thiosulphate slightly lowered the peak viscosity of cassava starch with increase in concentration, whereas with sodium sulphite, calcium chloride and sodium hypochlorite, a more significant decrease in the viscosity and breakdown was observed. Ferrous sulphate, alum, aluminium chloride and acids enhanced the peak viscosity at lower concentrations followed by a decrease at 1% and above. Sodium metabisulphite elevated the viscosity at 0.05 and 0.1%, while sodium hypochlorite lowered the viscosity and breakdown. DSC studies showed that aluminium chloride, sodium sulphite, and sodium thiosulphate brought about an increase in Tonset, Tend and ΔH values at higher concentrations. A decrease in swelling volume was observed from 0.05 to 1% concentration of sodium chloride and above that there was a gradual increase. With sodium sulphite, a significant increase in swelling volume was observed at 2.5 and 5% levels. With 0.05 and 0.1% aluminium chloride and sodium metabisulphite an increase in swelling volume was noticed, but at higher concentrations there was a drastic fall. Sodium chloride, sodium sulphite, sodium thiosulphate and calcium chloride brought about decrease in starch paste clarity with increase in salt concentration, whereas ferrous sulphate, aluminium chloride, sodium hypochlorite, hydrochloric acid and acetic acid improved the starch paste clarity.

Choosing Accurately: Competitive Intelligence on Prospecting Partners for Technological Cooperation

The paper discusses the results of a project aimed at developing and testing a methodology for the identification, qualification and classification of capabilities of Brazilian research groups (RGs) in technologies applicable to the automotive industry. The project was commissioned by the major R&D centre of a multinational corporation in the business of car manufacturing. The point of departure is the literature pointing out the need for firms to manage systematically rather than empirically their external sources of innovation. Regarding routines for prospecting and qualifying external R&D (Research and Development) partners, an important function in managing external sources, the paper introduces the concept of strategic search (competitive intelligence). The contribution of this paper is proposition of a new use for the methodology snowball sampling. Snowball sampling was originally used to map risk groups (“hidden populations” usually belonging to both social extremes: the deprived and the elites), ie carriers of the AIDS (SIDA) virus, drug addicts, chemical dependents, etc. The major steps of the methodology developed and tested by the authors are described. Such methodology is presented as a tool for strategic search. The result of the implementation of the methodology is a database with quantitative and qualitative information on Brazilian technological competencies applicable to the automotive industry in the technological areas of Materials, Powertrains and Fuels, Manufacturing Technologies, On-board Electronics and Ergonomics. The databank comprises 265 research groups in various science and engineering disciplines. And some of its aggregate results are presented and illustrated.
