Isolation and Characterization of Protease Producing Bacteria from Soil, in Arba Minch University, Abaya Campus

Microbes are ubiquitous and live in familiar settings such as soil, water, food and animal intestines as well as in more extreme setting such as rocks, glaciers, hot springs and deep-sea vents. They are essential component of the biodiversity as they account for 50% of the living biomass of this planet. The aim of this work was isolation and screening of protease producing bacteria from soil collected from the study area. Isolation of protease producing bacteria was performed by the serial dilution and spread plate technique using skim milk agar medium. Accordingly, 131 isolates were positive on skim milk agar and of which 13 (10%) of them are protease producer. Four best isolates were selected on the basis of their clear zone size, one from each site for further study. IS-4 has larger clear zone size with 10.5mm followed by IS-2 (6mm). All potential isolates have circular in shape of colony and flat in height of colony except IS-1 which is irregular and raised respectively. Most of potential isolates have opaque in their colonial optical density. All isolates were found to be Gram positive and spore producers. Morphological and biochemical results have revealed that three of four active enzyme producing bacteria are identified as Bacillus spp . Members of the genus Bacillus produce a large variety of extracellular enzymes (proteases) particularly significant for industrial application.
The potential of the wild dog rose (Rosa canina) to mitigate in vitro rumen methane production

This study examined the potential of liquid wild dog rose (Rosa canina) seeds oil and solid seeds residue obtained after CO 2 extraction in supercritical conditions to mitigate rumen methane production in vitro. Two experiments were carried out. The substrate comprised of a mixture of meadow hay and barley meal (60:40) for the control diets (CON1 in experiment with oil and CON2 in experiment with residue). The control diets were supplemented up to 5% in dry matter of rose seeds oil (RO) and 5% of rose seeds residue (RR). The following parameters were measured: pH, ammonia, volatile fatty acids, ciliate protozoa and bacteria count, methane concentration and methanogens population. In the RO treatment a decrease in methane production and an increase in the Archea population were observed. In the RR treatment no change in methane production was reported, whereas some variations in protozoal populations were detected in relation to CON2. The potential to mitigate methane production was reported only in wild dog rose seeds oil treatment. Besides, no negative effect of wild dog rose seeds residue on rumen processes was stated, what may predispose this protein and fibre containing by-product to be utilized as ruminants dietary ingredient.
Modification of Cary-Blair transport medium for Pasteurella multocida and Mannheimia haemolytica

Tefera G. , J. Smola: Modification of Cary-Blair Transport Medium for Pasteurella multocida and Mannheimia haemolytica . Acta Vet. Brno 2002, 71: 229‐233. The aim of this study was to evaluate the effectiveness of Cary-Blair, Amies and modified Cary-Blair medium for transport of P. multocida and M. haemolytica strains. Pure cultures of nine strains of P. multocida, representing all subspecies, and nine strains of M. haemolyticawere inoculated into the media to test their convenience. The ability of the strains to survive in each of these media was determined periodically (on days 5, 10, 15, 20, 30, 45, 60, 75, 90, respectively) at different temperatures (alternatively at 21 °C and 4 °C) and at room temperature (constantly at 21 °C). Comparing with the Cary-Blair and Amies medium, P. multocida strains survived for 45 days and M. haemolytica strains for 30 days in modified Cary-Blair medium. Based on the present observation, Cary-Blair medium modified by the addition of horse blood serum is the most effective of those tested media for the transport of P. multocida and M. haemolyticastrains.

The speech of male and female leaders : Using a text mining method to investigate sex differences in leadership word use

The stereotypical thought exists that leadership is more suited for men than for women. This study investigates differences in word use between male and female leaders, with the use of a text mining method. Videos of team meetings were transformed into transcripts, which were analysed by computer software. Spoken words were assigned to the word category they belonged to. Based on previous studies it is expected that male and female leaders differ in the relative frequency of certain words they use, with male leaders using more agentic words and female leaders using more communal words. Besides some small differences, the main result is that word use of male and female leaders seems to be quite similar.
Applied Econometrics and International Development Vol.7-2 (2007) NONLINEAR DYNAMICS WITHIN MACROECONOMIC FACTORS AND STOCK MARKET IN PORTUGAL, 1993-2003

The main objective of this paper is to assess how mutual information as a measure of global dependence between stock markets and macroeconomic factors can overcome some of the weaknesses of the traditional linear approaches commonly used in this context. One of the advantages of mutual information is that it does not require any prior assumption regarding the specification of a theoretical probability distribution or the specification of the dependence model. This study focuses on the Portuguese stock market where we evaluate the relevance of the macroeconomic and financial variables as determinants of the stock prices behaviour.

Isolation and genotyping of Clostridium perfringens from goats in Minas Gerais, Brazil

ABSTRACT: Despite the known importance of Clostridium perfringens as an enteropathogen in small ruminants, little is known about the role of its additional virulence factors or the frequency of the various C. perfringens genotypes in healthy goats; this complicates the laboratory diagnosis of the infections caused by this microorganism. In light of this, the aim of the present study was to isolate and genotype C. perfringens from stool samples from healthy goats in Brazil. Stool samples from 250 apparently healthy adult goats from 17 different herds in Minas Gerais, Brazil were collected, and isolation and genotyping of C. perfringens was performed. C. perfringens type A was isolated from 189 (75.6%) goats, whereas C. perfringens types C and D were each detected in one goat (0.4%). All isolates were negative for enterotoxin-, NetB-, NetE-, and NetF-encoding genes. These results confirmed C. perfringens type A as part of the microbiota in these animals, and they suggested that C. perfringens type C and D are rarely isolated from healthy goats.
N ◦ 2010-08 Equilibrium yield curves under regime switching Santiago Garćıa-Verdú

This paper studies how inflation as a macroeconomic indicator affects nominal bond prices. I consider an economy with a representative agent with EpsteinZin preferences. Regime switching affects the state-space capturing inflation and consumption growth. Thus, the agent is concerned about the intertemporal distribution of risk, which is affected by the persistence of the variables and the regimes. Regime switching allows for structural changes in the volatility of unexpected shocks. To the extent that inflationary unexpected shocks indicate lower consumption growth, nominal bond holders need to be compensated for these shocks. It follows that a switch in the regime state affecting the covariance of inflation and consumption growth can be interpreted as a change in the price of risk. I find coefficients of risk aversion from 40 to 90, and subjective discount factors above 0.99, depending on the exact specification of the model. The model yields have on average a positive slope, a consistent Principal Components decomposition, and predictability as in Cochrane and Piazzesi (2002).
Analysing the Determinants of Adoption of Organic Fertilizer by Smallholder Farmers in Shashemene District, Ethiopia

This study was carried out in Shashemene district of Ethiopia, to evaluate factors affecting adoption and use intensity of organic fertilizer. Primary data was collected from randomly selected 213 non-adopters and systematically selected 155 adopters of organic fertilizer. The analysis employed Cragg’s double hurdle model. Results indicate that household size negatively influenced decision to adopt organic fertilizer while livestock numbers, extension contacts, access to information media and membership to farmer based organizations positively influenced the decision to adopt organic fertilizer. Besides, farm size and membership to farmer groups influenced intensity of adoption positively while farm income and frequency of organic fertilizer application influenced use intensity of organic fertilizer negatively. For smallholder farmers to benefit from adoption of organic fertilizer, interventions aimed at providing better extension services, better access to information media and farmer’s group formations are crucial. Encouraging entrepreneurs to invest in organic fertilizer processing plants would also improve availability of organic fertilizer for smallholder farmers.

Infrared Light Curves of Near-Earth Objects

We present light curves and derive periods and amplitudes for a subset of 38 near-Earth objects (NEOs) observed at 4.5 μm with the IRAC camera on the the Spitzer Space Telescope, many of them having no previously reported rotation periods. This subset was chosen from about 1800 IRAC NEO observations as having obvious periodicity and significant amplitude. For objects where the period observed did not sample the full rotational period, we derived lower limits to these parameters based on sinusoidal fits. Light curve durations ranged from 42 to 544 minutes, with derived periods from 16 to 270 minutes. We discuss the effects of light curve variations on the thermal modeling used to derive diameters and albedos from Spitzer photometry. We find that both diameters and albedos derived from the light curve maxima and minima agree with our previously published results, even for extreme objects, showing the conservative nature of the thermal model uncertainties. We also evaluate the NEO rotation rates, sizes, and their cohesive strengths.
Acute renal failure in neonatal septicemia

Objective: To find out the prevalence, associate factors and outcome of acute kidney injury in neonatal sepsis. Methods: An observational hospital based prospective study was conducted at outborn NICU, Bal Chikitsalya, RNT Medical College, Udaipur (Raj.) India from august 2015 to January 2016. We enrolled total 107outborne neonates with sepsis, were evaluated for presence of ARF or not Sepsis was diagnosed on the basis of either a positive sepsis screen (immature: total (I:T) neutrophil ratio > 0.2, ? -ESR > age in days + 2 mm or >15 mm, CRP> 1mg/dl, TLC 15000/ mm3; 2 or more positive) or a positive blood culture in symptomatic neonates. ARF was defined as creatinine >1.5 mg/dl irrespective of day of life. Oliguria was defined as urine output <1ml/Kg/hr.Results: 34 out of 107 (21.49%) neonates with sepsis had ARF; only 20.58% of ARF was oliguric. The mean gestation of neonates with ARF was similar to those without ARF (34.732.88wks vs. 34.523.17wk). The association of shock was also significantly higher in neonates with ARF (70.59% vs 29.41%, p<0.001). Mortality in neonates who developed ARF was significantly higher (56.52% vs 25%, p<0.001). Conclusion: Renal failure occurred in 21.49% neonates with sepsis. Although ARF in neonates has been reported to be predominantly oliguric, it was observed that ARF secondary to neonatal sepsis was predominantly non oliguric. Very Low birth weight was an important risk factor for the development of ARF.
Strength and Durability Properties of Granite Powder Concrete

The most commonly used fine aggregate across world is river sand. River sand is expensive due to excessive cost of transportation from natural sources. Also large scale depletion of the source creates environmental problems. As environmental, transportation and other constraints make the availability and use of river sand less attractive. A substitute or replacement product for concrete industry needs to be found. The main parameter investigated in this study is M30 grade concrete with replacement of sand by granite powder by 0, 25 and 50% and cement was partial replacement with silica fume, fly ash, slag and super plasticizer. This paper presents a detailed experimental study on compressive strength, split tensile strength 28, 56 and 90 days. Durability study on chloride attack was also studied and percentage of weight loss is compared with normal concrete. Test results indicate that use of granite powder and admixtures in concrete has improved the performance of concrete in strength as well as in durability aspect.
A Case of Poorly Differentiated Cutaneous Canine Mast Cell Tumor with an Atypical Dermatologic Presentation

Canine cutaneous mast cell tumors occur as nodular dermal lesions. A condition of mastocytosis is also described in dogs. The purpose of this study is to report the clinical and histopathological findings in a dog with high grade non-nodular cutaneous mast cell tumor. An 11-year-old intact male German Shepherd dog presented a severe erythematous dermatitis and erythematous plaques on the left thoracic wall, rapidly increasing in thickness, ulcerating, and spreading to the head. The fine needle cytology was indicative of a round cell neoplasm. The histological appearance of the lesions was suggestive of a high grade cutaneous mast cell tumor. Neoplastic cells were immunoistochemically Tryptase positive and c-kit positive (focal cytoplasmic staining), with a high Ki67 index. On the basis of this report high grade canine cutaneous mast cell tumors may show an atypical non-nodular presentation and should be included in the differential diagnosis for different lesions grossly appearing as erythematous dermatitis/plaques.
Christianity and Infant Health in India

This paper studies child health in India focusing on differences in anthropometric outcomes between the three main religions – Hindus, Muslims and Christians. The results indicate that Christian infants have higher height-for-age z-scores as compared to infants of other religious identities, and that this is especially true for infant girls in states with a relatively large Christian presence. We instrument for Christian identity today using data on the location of Protestant and Christian missions, the incidence of epidemic diseases and natural disasters, and political crises (wars) that mission establishing countries were engaged in during India's colonial history. The results are robust to a series of checks for instrument validity and omitted variables, and indicate that by inculcating awareness and spreading knowledge on sanitation and the scientific underpinnings of disease, the advent of Christianity has long-term health implications for India's children today.
STABILITY OF WATERFRONT RETAINING WALL SUBJECTED TO PSEUDO-DYNAMIC EARTHQUAKE FORCES AND TSUNAMI

The paper pertains to a study in which the waterfront retaining wall has been analyzed for its stability when it is exposed to the forces jointly coming from an earthquake and tsunami. Closed form solutions following the simple limit equilibrium principles have been proposed. For the calculation of the seismic passive earth pressure and the wall inertia force, pseudo-dynamic approach has been considered, while the hydrodynamic and the tsunami wave pressures have been calculated using different approximating solutions available in literature. The results presented in the sliding and overturning modes of failure of the wall show that the stability of the wall gets seriously challenged when it gets jointly exposed to the effects of the tsunami and earthquake. About 92% decrease is observed in the value of the factor of safety in sliding mode of failure of the wall as the ratio of tsunami wave height to the upstream still water height increases from 0 to 1.5. Also, the critical mode of failure of the wall has been found to be that of the overturning. Effect of different parameters involved in the analysis has also been studied and it has been observed that quite a few of them like kh, kv, ϕ, δ, ru have a significant effect on the stability of the wall. Comparison with a previously existing methodology using pseudo-static approach suggests that the present pseudo-dynamic approach is more realistic and comparatively less conservative and hence can be used as a handy simple economic method for the design of the waterfront retaining walls exposed to the combined effects of earthquake and tsunami.
Heterogeneous ethnic distribution of the factor v leiden mutation

Resistencia a proteina C ativada associada a mutacao do fator V Leiden (FVL) e a mais prevalente causa genetica de trombose venosa conhecida, sendo encontrada em 20 a 60% dos pacientes com trombofilia. Adicionalmente, uma associacao entre a mutacao do FVL e predisposicao aumentada para doenca cardiovascular prematura em mulheres foi recentemente descrita. No presente estudo nos determinamos a prevalencia da mutacao do FVL em 440 individuos (880 cromossomos) de 4 grupos etnicos diferentes: caucasoides, negros africanos, asiaticos e amerindios. Amplificacao por PCR seguida de digestao com a enzima de restricao MnlI foi utilizada para definicao do genotipo. A mutacao do FVL foi encontrada em heterozigose em 4 de 152 caucasoides (2,6%), 1 de 151 amerindios (0,6%) e esteve ausente em 97 negros africanos e 40 asiaticos. Nossos resultados confirmam que o FVL apresenta distribuicao heterogenea em diferentes populacoes humanas, fato que pode contribuir para diferencas etnicas e geograficas na prevalencia de doencas tromboticas. Adicionalmente, estes dados podem ser uteis para a definicao de estrategias de rastreamento desta mutacao em individuos sob risco para desenvolvimento de trombose, na populacao brasileira.
Economic Impact of Microarray-Based Rapid Detection of Gram-Positive Organisms in Blood Cultures

We assessed the clinical and economic impact of using the microarray-based Verigene Gram positive blood culture (BC-GP) test to identify gram positive bacteria in blood cultures. The main advantage of employing this test in comparison to conventional culture techniques resided on identifying the causative organism an average of 42.8 hours prior than conventional culture techniques. The microarray-based test results allowed providers to tailor antibiotic therapy and decide whether to admit/discharge a patient sooner, which reflected over $21,000 in hospital savings for the 105 cases analyzed in this study. The implementation of the Verigene BC-GP in our Microbiology Laboratory presented an economic advantage when compared to conventional workup and was shown to improve ongoing antimicrobial stewardship and patient care.
Seismic Response of Plan-Asymmetric Structures with Diaphragm Flexibility

The seismic behavior of asymmetric structures with a flexible diaphragm was studied by conducting inelastic dynamic time-history analyses. Asymmetric structures with different configurations of mass, stiffness, and strength centers, in combination with a wide range of diaphragm flexibility, were evaluated. The behavior of structures was studied by considering three aspects: effect of structural asymmetry on diaphragms deformation; effect of diaphragm flexibility on demands of the lateral load-resisting elements; optimum configuration of mass, stiffness, and strength centers to limit important engineering demand parameters in asymmetric structures with a flexible diaphragm. The results showed that the shear-dominant deformation of diaphragms is sensitive to both structure asymmetry specifications and the degree of diaphragm flexibility; therefore, it can be used for the qualitative classification of the seismic behavior of structures. Also, the center of strength in structures with flexible diaphragm is more important relative to the stiffness center and has a significant effect on engineering demands at all levels of diaphragm flexibility. Moreover, it was found that a suitable configuration of centers in torsionally stiff structures depends on the degree of diaphragm flexibility, in addition to the intensity of earthquakes (structure yield level) and selected engineering demand parameter.
Relationship of Forest Road Aggregate Test Properties to Sediment Production

This study investigated the sediment production from various aggregates. The objectives of this study were 1) to evaluate the erodibility of a range of aggregate surfacing materials and relate it to standard and non-standard specification tests, 2) provide a means of specifying aggregate materials and understand the sedimentation implications, and 3) to provide a relative ranking of the erosive potential of aggregates. To accomplish this, eighteen aggregates from the Pacific Northwest were selected based on quality and geologic parent material. A suite of aggregate specification tests were performed to characterize each aggregate. The sedimentation from a simulated rain storm on a plot representing a freshly constructed road section was measured. Traffic was applied and the sediment production from a simulated storm again measured. The two best indicators of aggregate quality were Sand Equivalent and Oregon Air P20 test results. Knowledge of whether an aggregate was classified as good or marginal was not sufficient to estimate sediment production. The best indicator of sediment production was the percent passing the number 30 sieve.
Relaxation of elastic energies with free discontinuities and constraint on the strain

As a model for the energy of a brittle elastic body we consider an integral functional consisting of two parts: a volume one (the usual linearly elastic energy) which is quadratic in the strain, and a surface part, which is concentrated along the fractures (i.e. on the discontinuities of the displacement function) and whose density depends on the jump part of the strain. We study the problem of the lower semicontinuous envelope of such a functional under the assumptions that the surface energy density is positively homogeneous of degree one and that additional geometrical constraints, such as a shearing condition or a normal detachement condition, are imposed on the fractures.
Detection of flavonoids in glandular trichomes of Chromolaena species (Eupatorieae, Asteraceae) by reversed-phase high-performance liquid chromatography

In this work, twelve flavonoids were detected in glandular trichomes of two species of Chromolaena through the glandular microsampling technique and HPLC-UV-DAD analysis. This is the first time that the accumulation of flavonoids in glandular trichomes of the genus Chromolaena is reported. Based on the results, we suggest that this technique can be an useful tool in the search of new compounds with medicinal properties as well as in chemotaxonomic studies of Eupatorieae.
