Taxonomic revision of genus Prosopis L. in Egypt

The aim of this work was to survey the new record invasive alien Prosopis juliflora and clarifies the taxonomic relationships among genus Prosopis L. in Egypt. The wild species are Prosopis farcta (Banks & Sol.) Macbride and Prosopis juliflora (Sw.) DC. The cultivated species are Prosopis cineraria (L.) Druce; Prosopis glandulosa Torr. and Prosopis strombulifera (Lam.) Benth. Based on morphological traits, the numerical analysis divided the Prosopis species into three clusters. Cluster one included: Prosopis glandulosa and Prosopis juliflora. Cluster two included: Prosopis farcta and Prosopis cineraria. Cluster three included: Prosopis strombulifera. According to the degree of similarity, the species of cluster one had the highest ratio (75%) followed by (55.6%) between the species of cluster two. Moreover, the highest ratio (33.3%) was recorded between Prosopis strombulifera and Prosopis juliflora, while the lowest ratio (20.8%) was recorded between Prosopis strombulifera and Prosopis cineraria. This work recoded Prosopis juliflora to the Flora of Egypt.
Team SVMrank: Leveraging Feature-rich Support Vector Machines for Ranking Explanations to Elementary Science Questions

The TextGraphs 2019 Shared Task on Multi-Hop Inference for Explanation Regeneration (MIER-19) tackles explanation generation for answers to elementary science questions. It builds on the AI2 Reasoning Challenge 2018 (ARC-18) which was organized as an advanced question answering task on a dataset of elementary science questions. The ARC-18 questions were shown to be hard to answer with systems focusing on surface-level cues alone, instead requiring far more powerful knowledge and reasoning. To address MIER-19, we adopt a hybrid pipelined architecture comprising a featurerich learning-to-rank (LTR) machine learning model, followed by a rule-based system for reranking the LTR model predictions. Our system was ranked fourth in the official evaluation, scoring close to the second and third ranked teams, achieving 39.4% MAP.
Bioaccumulation of heavy metals in shellfish Macrobrachium rosenbergi in Niger River at Onitsha, Anambra State, Nigeria.

Received: Revised: Accepted: January 10, 2014 February 12, 2014 February 20, 2014 Seasonal bioaccumulation of heavy metals namely, Zinc (Zn), Iron (Fe), Copper (Cu), Lead (Pb), Mercury (Hg) and Arsenic (As) in the shellfish of Macrobrachium rosenbergi from Niger River at Onitsha were studied using Atomic Absorption Spectrophotometer (AAS). Results showed presence of all the analysed metals in the shellfish tissue. Mean concentrations of Zn (4.35±1.2mg/l), Cu (1.35±0.43), Cd (0.31±0.0421), Hg (0.16±0.0011) and As (0.04±0.001) in mg/l complied with the World Health Organization (WHO) standards in aquatic foods. However those for Fe (9.73±1.30) and Pb (0.24±0.04) mg/l exceeded the WHO standards. Furthermore, mean concentrations for Zn (0.321±0.09), Fe (1.52±0.07), Cu (0.035±0.006), Hg (0.076±0.007), As (0.016±0.007) and Cd (0.012±0.006) mg/l in the water columns were significantly lower (P<0.05) than the concentrations in the shellfish. Bioaccumulation of heavy metals in the shellfish studied indicated that Niger River at Onitsha is experiencing impairment. The result implies that prolonged consumption of shellfish and other aquatic foods contaminated with heavy metals, and through observed indiscriminate dumping of waste in the river, may constitute public health risks.
Exposing the role of exposure: Identifying and evaluating critical links in public transport networks

Network vulnerability depends on the probability that adverse events occur and on the impacts of such disruptions on network functionality. Most studies on transport network vulnerability have only analysed vulnerability in terms of the reduction in performance indicators given that a disruption occurs. This study presents and applies a method to explicitly account for exposure in identifying and evaluating link criticality in public transport networks. The proposed method is compared with conventional measures that lack exposure information. The expected value of link criticality– the probability weighted average impact of a disruption - is evaluated. The methodology was applied for a multi-modal public transport network in the Netherlands where data concerning disruptions was available. The results expose the role of exposure in determining link criticality and overall network vulnerability. The inclusion of exposure in the assessment of societal costs has thus consequences on assessing mitigation measures and investment priorities.
Analysis of pathogen virulence of wheat stem rust and cultivar reaction to virulent races in Tigray, Ethiopia

Wheat stem rust caused by Puccinia graminis f. sp. tritici is amongst the biotic factors which can cause up to 100% yield loss during epidemic years. The highland of Ethiopia is considered as a hot spot for the development of stem rust diversity. This study was carried out to analyze the virulence diversity of P. graminis f. sp. tritici and evaluate the seedling reaction of commonly grown wheat cultivars to selected virulent stem rust races. Race analysis was carried out by inoculating isolates on to the 20 differential hosts. A total of 20 races were identified from 32 isolates, which included the most prevalent races TTSNK, RRJJC, and HRJJC. Most of the the genes possessed by the differentials were ineffective against one or more of the tested isolates except Sr24. Three races (RRTTF, TTKSK and TTSNK) were used to determine the resistance ofeleven wheat cultivars at seedling stage in greenhouse. Three varieties (Tura, Shina and Kubsa) were susceptible to them, while all the three durum wheat cultivars were resistant. Thus, the use of Sr24 and SrTmp singlely or incombination with other genes through gene pyramiding has paramount importance as the additive effects of several genes offer the cultivar a wider base stem rust resistance. Key words: Physiologic race, Puccinia graminis f. sp. tritici, Sr genes.
Risk arbitrage in emerging Europe: are cross-border mergers and acquisition deals more risky?

Abstract Speculation spread in mergers and acquisitions (M&A), measured as the percentage difference between the offer price and the closing stock price of a target the day after the announcement, is the starting point for risk arbitrage returns, a topic receiving greater consideration both in practice and in the empirical literature. Reflecting the degree of risk in merger arbitrage investments, we found no significant difference between the speculation spread in domestic and foreign Polish deals, between 2000 and 2013. However, we found higher returns for cross-border portfolio, therefore investors seem more pessimistic with regards to the expected risk in cross-border deals. Also, on average, deal spreads do not correctly reflect the level of risk in merger arbitrage strategies with Polish targets.
Radiation driving and heating of general relativistic jets under a Compton-scattering regime

Interaction of intense radiation from the underlying accretion disc with steady, general-relativistic jet is studied. The radiation field imparts momentum as well as energy on to the outflowing jet under Compton scattering. As a result, the jet gains momentum and is simultaneously heated up. Jets can be classified as types A, B and C according to their base properties. We found that A type jets can undergo shock transition. It is also shown that, in the Compton scattering regime, radiation can drive jets starting with very small thermal energy at the base (B and C type jets). Such that, radiation can even} accelerate bound matter (generalized Bernoulli parameter $E 1$. We also show that for a given disc luminosity, jets in the Compton scattering regime exhibit a minimum terminal speed, unlike in the Thomson scattering domain. Further, the impact of accretion disc luminosity and jet plasma composition is studied. The ${{\rm e}^--{\rm p}^+}$ jets are accelerated up to Lorentz factors of about a few, while for lepton dominated jets the minimum Lorentz factor exceeds $10$ for moderate disc luminosities and can go up to few tens for highly luminous discs.
High-Involvement Management, Economic Recession, Well-Being, and Organizational Performance

High-involvement management was introduced as a means of overcoming economic crises, but it has been argued that the inevitability of cost-cutting measures when organizations face such crises would undermine its efficacy. This article first presents theories of why tensions may exist between high-involvement management and actions typically taken by management during recessions, such as wage and employment freezes. It then reports research aimed at testing whether the performance effects of high-involvement management were lower in organizations where management took such actions to combat the post-2008 recession, due to their adverse effects on employees’ job satisfaction and well-being—and even whether high-involvement management still had a performance premium after the recession. Using data from Britain’s Workplace Employment Relations Survey of 2011, the research shows that both dimensions of high-involvement management—role- and organizational-involvement management—continued to be positively associated with economic performance as the economy came out of recession. Recessionary actions were negatively related to both employee job satisfaction and well-being, while job satisfaction mediated the relationship between role-involvement management and economic performance, which is consistent with mutual-gains theory. However, recessionary action reduced the positive effect that role-involvement management had on job satisfaction and well-being and thus may have reduced its positive performance effects. In the case of organizational-involvement management, it reduced the level of job dissatisfaction and ill-being, suggesting that it may provide workers with more information and greater certainty about the future.
Effect of lemongrass powder on proximate and phytochemical content of herbal cookies

Lemon grass (Cymbopogon citratus) is a perennial grass belonging to family Graminaceae and grouped under genus Cymbopogon. In this study, the herbal cookies were prepared by incorporating lemongrass powder at 1, 3 and 5% level. The proximate and phytochemical analysis of fresh lemongrass leaves were analyzed. The effect of drying on proximate and phytochemical composition were also determined. The moisture, fat and fiber content were found decreased while protein, carbohydrate and ash content were increased. The phytochemical constituents get reduced when subjected to cabinet drying. The herbal cookies were found to increase in proximate composition with increase in level of lemongrass powder. The herbal cookies contain alkaloid (0.27%), saponin (0.20%), tannin (0.16%), steroids (0.10%), phenols (0.08%) and flavonoids (0.28%) in sensorially selected sample. The sample with 3% lemongrass powder was found to be highly acceptable over other sample. The required daily dose of was about 0.7 mg/kg of bodyweight/day.
Anomalies in the response of V, Nb, and Ta to tensile and shear loading: Ab initio density functional theory calculations

Ab initio density functional calculations of the response of V, Nb, and Ta to tensile and shear loading have been performed. We find that the behavior of all three metals of the V group under large strains differs considerably from that reported for the other body-centered cubic (bcc) transition metals (Mo, W, and Fe). Under unaxial $⟨100⟩$ tensile loading, V and Nb undergo a bifurcation from a tetragonal to an orthorhombic deformation path, associated with a shear instability, before reaching the stress maximum. The bifurcation strongly reduces the ideal tensile strengths to 11.5 GPa for V and 12.5 GPa for Nb. For Ta the bifurcation point coincides with the stress maximum of 13.6 GPa along the tetragonal path so that the metal fails under tensile strain by shear and not by cleavage. The stress-strain curves calculated for the ${110}⟨111⟩$ and ${211}⟨111⟩$ slip systems are strongly asymmetric; the ideal shear strengths for both slip systems are 6.5 (5.5) GPa for V and 7.8 (6.0) GPa for Nb. Hence the ideal shear strengths are only half as large as for the bcc metals Mo and W, but much larger than expected on the basis for the low shear moduli of V and Nb. Ta shows a behavior intermediate between these two groups of metals, with a calculated ideal shear strength of 7.1 (6.5) GPa, in excellent agreement with the experimental estimate from nanoindentation experiments. The saddle-point structure determining the shear strength for both slip systems is a special body-centered-tetragonal structure. This structure is identical to the saddle-point structure identified on the orthorhombic deformation path under uniaxial tension. Hence also V and Nb will fail under uniaxial tension not by cleavage, but by shear.

Effect of Organic and Inorganic Fertilizer on the Milling and Physicochemical Properties of Aromatic Rice

The experiment was conducted at the Hajee Mohammad Danesh Science and Technology University Farm, Dinajpur, Bangladesh during July to December of 2005 to observe the influence of organic, inorganic and integrated management of fertilizers on the milling and physicochemical properties of aromatic rice. The experiment was laid out in a randomized complete block design with three replications. The experiment comprised five treatments viz., control (no fertilizer), recommended dose of chemical fertilizers (NPKSZn), well-decomposed cow dung at 10 t ha, green manure at 15 t ha (Sesbania rostrata) and combination of recommended dose with green manure. Three varieties namely, Kataribhog, Badshabhog and BRRI dhan38 were used. Milling outturn, head rice outturn, grain elongation ratio, volume expansion ratio, protein content, amylose content and cooking time were significantly but grain length and length breadth ratio were not significantly affected by fertilizer. Highest percentage of milling outturn was recorded in green manure at 15 t ha and it was identical to control, application of cow dung at 10 t ha and combination of recommended dose of NPKSZn fertilizer with green manure (Sesbania rostrata) at 15 t ha. Head rice outturn (63.96) was higher under green manure at 15 t ha and it was identical to control and recommended dose of NPKSZn fertilizer. Grain elongation ratio was higher in green manure at 15 t ha and it was identical to application of cow dung at 10 t ha . The highest protein content was found by recommended chemical fertilizer dose. All the studied parameters were significantly affected by varieties. The interaction between fertilizer and variety was insignificant in respect of all grain quality characteristics except head rice outturn, grain length and protein.
Antiviral effect of the seaweed Osmundaria obtusiloba against the Zika virus

Zika virus (ZIKV), a mosquito-borne member of the family Flaviviridae, is a human pathogen of global significance. Recently, ZIKV, has become a public health problem with increases in numbers of cases and a strong association between ZIKV outbreaks and the spread of cases of Guillain-Barre Syndrome and microcephaly. In this study, the extracts of the seaweed Osmundaria obtusiloba (O. obtusiloba) (native to the Brazilian coast) against ZIKV using Vero cells was evaluated. The seaweed extract tested inhibited ZIKV replication in a dose-dependent manner at low concentrations with EC50 values of 1.82 μg/mL and a selective index (SI) of 288. Other results showed that this extract had significant virucidal effects. In addition, when the extract and Ribavirin were used concomitantly there was a significant synergistic effect. Our promising results suggest that extracts of O. obtusiloba are excellent candidates for further studies, and that marine algae are potentially important sources for the development of novel anti-ZIKV agents. Key words: ZIKA, seaweeds, antiviral activity, marine algae, Osmundaria obtusiloba.
Endogenous longevity, health and economic growth: a slow growth for a longer life?

We establish a theoretical set-up that is able to endogenously integrate growth and longevity. Our model captures three links between them: a longer life expectancy results in an increase in savings as well as an increase in the workforce, but health and growth compete for resources. We find that the key element is the response of longevity to an increase in health resources. Our model suggests that the first two links could be the most important in poor countries, which could explain their experience of simultaneous increases in growth and life expectancy. The reverse result may apply for developed countries.
Hypolipidemic effect of Irvingia gabonensis fruits juice on sodium fluoride induced dyslipidemia in rats

in I. gabonensis-treated group, which compared favourably with that of the standard. Furthermore, NaF toxicity resulted in the elevation of atherogenic index in the NaFC group. This was significantly (p<0.05) lowered in all other groups. The total non-HDLcholesterol and LDL/HDL ratio were significantly reduced in I. gabonensis-treated rats. This tends to suggest that the juice of I. gabonensis may be useful in alleviating and preventing cardiovascular diseases.
Related but not replaceable: a response to Warner’s reworking of person-centered personality theory

ABSTRACT Whether conditions of worth theory can explain complex forms of human psychological distress, such as those emanating from early experiences of abuse, neglect and trauma, alongside experiences of physiological events later in life is open to debate. It has been suggested that Rogers’s personality theory should be reconsidered and replaced with an actualization-centered formulation that places greater emphasis on the enhancement of self-process and agency through relationship, rather than on a theory of defense. This paper aims to examine these proposals and consider their relative contribution to developing the theory of personality. We suggest that the actualization-centered process theory aids Rogers’s theory of personality but is not an adequate replacement. We also consider the issues associated with maintaining theoretical and practical symmetry and the practice implications of replacing conditions of worth.
VHRM_A_175150 209..220

Department of Internal Medicine and Nephrology, Memorial Şişli Hospital, Istanbul, Turkey Abstract: Cholesterol-embolization syndrome (CES) is a multisystemic disease with various clinical manifestations. CES is caused by embolization of cholesterol crystals (CCs) from atherosclerotic plaques located in the major arteries, and is induced mostly iatrogenically by interventional and surgical procedures; however, it may also occur spontaneously. Embolized CCs lead to both ischemic and inflammatory damage to the target organ. Therefore, anti-inflammatory agents, such as corticosteroids and cyclophosphamide, have been investigated as treatment for CES in several studies, with conflicting results. Recent research has revealed that CES is actually a kind of autoinflammatory disease in which inflammasome pathways, such as NLRP3 and IL1, are induced by CCs. These recent findings may have clinical implications such that colchicine and IL1 inhibitors, namely canakinumab, may be beneficial in the early stages of CES.
Self-perceived age categorization as a determinant of the old age boundary

Using data from the European Social Survey, we investigate the influence of individuals' self-perceptions of being a member of an age group on their assessment of the beginning of ‘old age'. The proper examination of this relationship calls for the consideration of the effects of age and gender as well as the fact that people who concur that a boundary for old age exists (thus provide a numerical response to the relevant survey question) constitute a non-random subsample of the population with respect to the outcome of interest. Therefore, the econometric work features a two-equation selection model that jointly estimates the ‘Old age boundary' and the ‘Numerical response' equations. Our finding is that the two equations are in fact correlated, and – along with age and gender – self-perceived age categorization has a significant effect on the subjective old age boundary. People who categorize themselves in younger age groups than others of the same chronological age have higher old age boundaries.
The Tetrahedron Zamolodchikov Algebra and the AdS 5 × S 5 S-matrix

The S-matrix of the AdS5×S string theory is a tensor product of two centrally extended su(2|2)⋉R2 S-matrices, each of which is related to the R-matrix of the Hubbard model. The R-matrix of the Hubbard model was first found by Shastry, who ingeniously exploited the fact that, for zero coupling, the Hubbard model can be decomposed into two XX models. In this article, we review and clarify this construction from the AdS/CFT perspective and investigate the implications this has for the AdS5 × S S-matrix.
The Influence of Transformational Leadership Style on Innovation Mediated by Organizational Culture

PT. Bakrie Telecom, Tbk is the only private company in the telecommunication industry as the main competitor of PT. Telekomunikasi Indonesia, Tbk which sees innovation as having a vital role to boost performance and competitiveness. Meanwhile, the leadership style is highlighted as one of the most important influences on organizational innovation, as well as organizational culture that is essentially used as a variable in creating and implementing organizational innovation. Therefore, this study aims to analyze the extent to which innovation has been applied to PT. Bakrie Telecom, Tbk and the effect of transformational leadership and the organizational culture to innovation. The data have been collected by using questionnaires with the samples of 83 employees who work in the Marketing Department at PT Bakrie Telecom, Tbk (Northern Region of Sumatera). Then, the data were analyzed using the Path Analysis model, Sobel Test and Bootstrapping. The results show that transformational leadership contributed 43.3% in explaining the organizational culture, while the transformational leadership insignificantly affected the innovation. Moreover, the transformational leadership had a direct effect to the organizational culture. Finally this study reconfirms that organizational culture mediates the relationship between transformational leadership and innovation.
The correlation constant of a field

We study the correlation of edges, vectors or elements to be in a randomly chosen spanning tree or a basis, respectively. Here we follow the guideline of Huh and Wang and introduce as a measure an invariant that is called the correlation constant of a graph, vector configuration, matroid or field. It follows from one of their results that these correlation constants are numbers between 0 and 2. Here, we show that the correlation constant of every field is at least 8 7 . In our proof we explicitly construct vector configurations and matroids with positively correlated elements.
