Isolation and characterization of cellulolytic Bacillus licheniformis from compost

Eight cellulose degrading bacteria were isolated from compost and were identified as Bacillus licheniformis by 16S rRNA sequencing. Among the eight isolates, Bacillus licheniformis B4, B7 and B8 showed the highest cellulase activity. B. licheniformis B4 and B8 showed the maximum cellulase activity during the stationary phase of growth; but for B7, the maximum activity of cellulase was observed during the log phase. Reducing sugar released in the media, increased with increasing cellulase activity for all the three isolates. Significant correlation was observed between cellulase activity and protein content. The crude cellulase from B7 strain showed activity towards carboxymethyl cellulose and filter paper, but there was no detectable activity towards p-nitrophenyl- β-Dglucopyranoside (PNPG). The crude cellulase of B. licheniformis B7 exhibited maximum activity at 50°C and at pH 6 to 7. Keywords: Bacillus licheniformis , 16S rRNA, cellulase, reducing sugar, compost, viscosity
FEEDBACK STABILIZATION OF TRANSITION BOILING STATES

A nonlinear one-dimensional heat-transfer model for pool boiling systems is considered. The model involves only the temperature distribution within the heater and models the heat exchange with the boiling medium via a nonlinear boundary condition imposed at the fluid-heater interface. This compact model is employed for the design and analysis of a control strategy for the stabilization of unstable states in order to improve cooling applications based on boiling heat transfer. Therefore, a state feedback controller is implemented that regulates the heat supply as a function of the system’s internal state. Simulations of the nonlinear closed-loop system expose the state feedback controller as a viable option for the rapid stabilization and regulation of pool boiling systems at an unstable equilibrium point.
The Diagnostic Validity of the 13 C-Urea Breath Test in the Gastrectomized Patients : Single Tertiary Center Retrospective Cohort Study

Background: This study was conducted to evaluate the diagnostic validity of the C-urea breath test (C-UBT) in the remnant stomach after partial gastrectomy for gastric cancer. Methods: The C-UBT results after Helicobacter pylori eradication therapy was compared with the results of endoscopic biopsy-based methods in the patients who have received partial gastrectomy for the gastric cancer. Results: Among the gastrectomized patients who showed the positive C-UBT results (≥ 2.5‰, n = 47) and negative C-UBT results (< 2.5‰, n = 114) after H. pylori eradication, 26 patients (16.1%) and 4 patients (2.5%) were found to show false positive and false negative results based on biopsy-based methods, respectively. The sensitivity, specificity, false positive rate, and false negative rate for the cut-off value of 2.5‰ were 84.0%, 80.9%, 19.1%, and 16.0%, respectively. The positive and negative predictive values were 44.7% and 96.5%, respectively. In the multivariate analysis, two or more H. pylori eradication therapies (odds ratio = 3.248, 95% confidence interval= 1.088-9.695, P = 0.035) was associated with a false positive result of the C-UBT. Conclusions: After partial gastrectomy, a discordant result was shown in the positive C-UBT results compared to the endoscopic biopsy methods for confirming the H. pylori status after eradication. Additional endoscopic biopsy-based H. pylori tests would be helpful to avoid unnecessary treatment for H. pylori eradication in these cases. (J Cancer Prev 2014;19:309-317)
Entrepreneurship. Some insights from a population-based survey

Start-ups founded by university students and graduates play a substantial role in bringing new knowledge to the market and in employment creation; a role that appears to be even more important than the one played by the typical technology transfer activities carried out by universities, i.e. patenting and licensing activities, or spin-offs founded by academic staff. Indeed, robust empirical evidence suggests that entrepreneurs’ education is a good predictor of firms’ performance. Unfortunately, data show that the share of Italian entrepreneurs with tertiary educations is quite small, and this is especially the case of the younger generation. In this paper, we use a population-based approach to explore entrepreneurship among 61,115 graduates, alumni of the 64 Italian universities that belong to the AlmaLaurea consortium, in the second half of 2014, at the time when they completed their academic experience. We detect various levels of engagement and intentions to be involved in entrepreneurship, and we assess which factors appear to weigh more in a positive or negative manner. The bad news is that also our analysis finds that the share of Italian graduates who have started a business after their enrolment at university (1.3%) or who have taken concrete actions to start a business (4.5%) is quite small. The good news is that the number of intentional, i.e. potential highly educated, entrepreneurs among university students is much larger (at least 23%). On the basis of our results, we argue that the provision by universities of entrepreneurial education and training, internships, and ICT skills can be effective tools with which to cultivate entrepreneurial attitudes and skills, thereby fostering entrepreneurship and intrapreneurship among university graduates and enhancing their employability.
Natural History of a Madagascan Gecko Blaesodactylus ambonihazo in a Dry Deciduous Forest

Abstract: Several aspects of natural history of Blaesodactylus ambonihazo, a gecko distributed in a dry forest of northwestern Madagascar, were investigated in the rainy and dry seasons between 2000 and 2006. There were no significant sexual size differences in snout-vent length, and no sexual dimorphism was detected either in head width or body mass. Females ceased oogenesis during the rainy season and were recrudescent at the beginning of the dry season. They probably lay eggs in the middle of the dry season. Hatchlings were observed at the beginning of the rainy season and probably reach adult size in the subsequent dry season. At night geckos perched on tree trunks and buildings and exhibited typical sit-and-wait foraging. During the day they retreated to shelters, mainly crevices between buttress roots. The gecko was thermally passive to environmental temperatures, showing a wide range of cloacal temperatures (15–30 C), but they selected relatively higher substrate temperatures at low air temperature, possibly for thermoregulation. Because multiple individuals were observed on single trees, home ranges of the gecko were presumably overlapping each other, and no obvious territorial behavior was observed. The absence of male-biased sexual dimorphism, which suggests little male-male competition for mating, also supports the absence of territoriality of B. ambonihazo. Comparison with a syntopic diurnal gecko, Phelsuma kochi, which shows ecological characters similar to B. ambonihazo but has exclusive home ranges, may clarify ecological correlates associated with temporal niche partitioning.

Liczba chorych systematycznie wzrasta, a działania podejmowane w celu redukcji masy ciała rzadko przynoszą efekty. Podstawą terapii otyłości jest uzyskanie za pomocą diety ubogoenergetycznej oraz aktywności fizycznej, ujemnego bilansu energetycznego. Celem pracy było określenie wpływu 3-miesięcznej diety 1500 kcal na wybrane parametry antropometryczne oraz biochemiczne u chorych z otyłością. Materiał i metody. Do badania zakwalifikowano 23 pacjentów Poradni Nadciśnienia Tętniczego i Zaburzeń Metabolicznych w Poznaniu, w tym 18 kobiet i 5 mężczyzn. U wszystkich chorych dokonano pomiarów antropometrycznych — masa ciała, wzrost, wskaźnik BMI, obwód talii, obwód bioder oraz oznaczono parametry biochemiczne — stężenie glukozy, triglicerydów, cholesterolu całkowitego, LDL i HDL. Pacjentów poddano 3-miesięcznej zbilansowanej diecie redukcyjnej 1500 kcal. Po tym czasie ponownie oceniono badane parametry. Wyniki. U pacjentów stwierdzono podwyższone wartości parametrów antropometrycznych oraz wybranych parametrów biochemicznych. Trzymiesięczna dieta redukcyjna 1500 kcal spowodowała spadek masy ciała, zmieniając tym samym wartość wskaźnika BMI. Zmniejszył się obwód talii oraz obwód bioder. Wśród parametrów biochemicznych istotnie statystycznie uległy redukcji: stężenie glukozy, cholesterolu całkowitego, cholesterolu LDL oraz triglicerydów. Wnioski. Otyli pacjenci charakteryzują się podwyższonymi wartościami parametrów antropometrycznych oraz wybranych parametrów biochemicznych, a dieta ubogoenergetyczna 1500 kcal powoduje utratę masy ciała u otyłych chorych. W badaniu dowiedziono, że zbilansowana dieta redukcyjna wpływa na obniżenie stężenia glukozy oraz parametrów gospodarki lipidowej. (Forum Zaburzeń Metabolicznych 2012, tom 3, nr 4, 140–146)
On Counting Cliques, Clique-covers and Independent sets in Random Graphs

We study the problem of counting the number of isomorphic copies of a given template graph, say H , in the input base graph, say G. In general, it is believed that polynomial time algorithms that solve this problem exactly are unlikely to exist. So, a lot of work has gone into designing efficient approximation schemes, especially, when H is a perfect matching. In this work, we present efficient approximation schemes to count k-Cliques, k-Independent sets and k-Clique covers in random graphs. We present fully polynomial time randomized approximation schemes (fpras) to count k-Cliques and k-Independent sets in a random graph on n vertices when k is at most (1 + o(1)) log n, and k-Clique covers when k is a constant. The problem of counting k-cliques and k-independent sets was an open problem in [Frieze and McDiarmid, 1997]. In other words, we have a fpras to evaluate the first (1 + o(1)) log n terms of the clique polynomial and the independent set polynomial of a random graph. [Grimmett and McDiarmid, 1975] present a simple greedy algorithm that detects a clique (independent set) of size (1 + o(1)) log2 n in G ∈ G(n, 1 2 ) with high probability. No algorithm is known to detect a clique or an independent set of larger size with non-vanishing probability. Furthermore, [Coja-Oghlan and Efthymiou, 2011] present some evidence that one cannot hope to easily improve a similar, almost 40 years old bound for sparse random graphs. Therefore, our results are unlikely to be easily improved. We use a novel approach to obtain a recurrence corresponding to the variance of each estimator. Then we upper bound the variance using the corresponding recurrence. This leads us to obtain a polynomial upper bound on the critical ratio. As an aside, we also obtain an alternate derivation of the closed form expression for the k-th moment of a binomial random variable using our techniques. The previous derivation [Knoblauch (2008)] was based on the moment generating function of a binomial random variable.
A Hybrid NSGA-II Algorithm for Multiobjective Quadratic Assignment Problems

In this study, we propose a novel hybrid multiobjective evolutionary algorithm for solving multiobjective quadratic assignment problems. During the last decade, the researchers gave increasing attention to the multiobjective structure of quadratic assignment problems and developed and/or used several multi objective metaheuristics. The nondominated sorting genetic algorithm (NSGA-II) has been shown to solve various multiobjective problems much better than other recently-proposed constraint handling approaches. Besides, the effectiveness of conic scalarization method was also proven for solution of multiobjective problems, that have non-linear structure. Here, a hybrid multiobjective evolutionary algorithm (cNSGA-II) featured with NSGA-II and conic scalarization’s Pareto solutions is developed to obtain as much Pareto points, as possible. To test the performance of the algorithm we have selected the test problems from the literature and compared the performances by well-known diameter metric. It has been shown that cNSGA-II is effective in solving multiobjective quadratic assignment problems.
Molecular interactions between tomato and its wilt pathogen Fusarium oxysporum f . sp .

Fusarium oxysporum f.sp. lycopersici Snyd. et Hans. (Fol) is a soil-borne plant pathogen that causes wilt in tomato plants and threatens tomato industry worldwide. Successful plant infection and tissue colonization by Fol is an active process that involves a variety of cell wall-degrading enzymes (CWDE), regulation of nutrient metabolism, and secretion of effectors to suppress and/ or overcome the physical basal defense in tomato plants. The effector-encoding avirulence genes have been identified and their combinations in the genome of Fol determine the 3 races of the pathogen. Avirulence genes and other pathogenicity factors are assembled in a lineage-specific genomic region, including 4 entire chromosomes that Fol acquired probably by horizontal gene transfer from other closely related species. In the course of co-evolution with Fol, tomato evolved 3 resistance genes to counteract pathogen effector-triggered disease. The interactions between tomato and Fol has become a model system for the study of the molecular basis of disease resistance and susceptibility in plants.
Do Formula or Competitive Grant Funds Have Greater Impacts on State Agricultural Productivity?

This paper describes major external changes to the U.S. public agricultural research system over 1988-1999; describes the reactions of the public agricultural research system to the external changes, specifying the innovations that have occurred over the last decade; and draws conclusions about the present and future performance of the U.S. research system. The decade of the 1990s brought slow growth to public agricultural research funding. CSREES tried to stimulate greater interests in competitive grant programs. The states have generally resisted this move. A major asymmetry exists in the sharing of transactions costs associated with external peer-reviewed competitive grant programs. This is especially true when the average grant size is small and the average award rate is low.
A Traveler in God's Path: Sufi Words and the Metaphor of Journey

Sufi language is a notable style of writing in Persian which is full of novel spiritual ideas and metaphors. One of the widely-used metaphors in Persian Sufis literature is MYSTICAL JOURNEY and its related components such as the traveler in God’s path and the notion of God’s way. This study is dedicated to analyse the Sufi terminologies in which mysticism has been conceptualized as a JOURNEY metaphor by utilizing a Lakoffian cognitive approach for studying structural metaphors in language. Investigating the MYSTICAL JOURNEY in Sufi language clarifies that the cognitive approach toward metaphors explains the relation between MYSTICISM and the JOURNEY metaphor. The present research attempts to categorize the levels of mapping between the two domains inherent in the JOURNEY metaphor. The paper concludes that there is a rich relation between the two domains in MYSTICISM IS JOURNEY metaphor and by defining the levels of mapping between these two domains, a clearer viewpoint toward mystical metaphors will be achieved.
Unit labor costs and macroeconomic performance in Mexico

The paper studies the determinants of the relative unit labor cost (RULC) in the manufactures between Mexico and the US, and the effect of RULC on Mexican private investment. Seeking to detect persistent, “long-run” effects, the econometric estimations apply the bounds testing approach to quarterly data from the post-liberalization period in Mexico, 1988–2008. While the productivity-adjusted manufacturing real wage fell in Mexico, RULC nonetheless increased due to an even stronger fall in the US and the misalignment of the peso —with the latter resulting in a steady rise in Mexico’s exchange-rate-adjusted relative manufacturing prices. The estimations show that RULC affects private investment negatively, and thus that the upward trend in RULC contributed to the low levels of investment observed in Mexico. In addition to capital flows, RULC responds significantly to the peso–dollar real interest rate differential, indicating that the upward trend in RULC is partly explained by repeated surges in capital inflows and the disinflationary stance of monetary policy. Looking ahead, the estimation results suggest that monetary policy can support faster economic growth, in the medium term, by reducing the interest rate differential and encouraging a more competitive level of RULC.
The Seven Stages of the Rwandan Genocide

Drawing upon a book by J.M. Lecomte on the genocide of the Jews by the Nazi Germans, the author examines the seven stages in the genocide of the Tutsi in Rwanda. These stages, which do not necessarily follow one another in time but may overlap, can be classified in the following way: (i) definition of the target group on the basis of some criteria; (ii) registration of the victims; (iii) designation or outward identification of the victims; (iv) restriction and confiscation of goods; (v) exclusion from professions, working activities and means of transportation, among other things; (vi) systematic isolation; (vii) mass extermination.
Magnetic field configurations of a magnetar throughout its interior and exterior - core, crust and magnetosphere

We obtained the magnetic field configurations, including both poloidal and toroidal components, throughout the interior and exterior of magnetars using a realistic equation of state. We divided the magnetized star into the hydromagnetic equilibrium core, Hall equilibrium crust and twisted force-free magnetosphere. We systematically and simultaneously calculated these regions under various boundary conditions using the Green function relaxation method, and noted the following interesting characteristics of these numerical results. First, the strength and structure of core magnetic fields affect the crustal magnetic fields. Second, the current sheet on the core-crust interface affects both internal and external magnetic field configurations. Third, the twisted magnetosphere makes a cross-point of magnetic field lines, such as X-point geometry, in the magnetosphere. The X-point geometry appears and disappears according to the strength of the twisted field in the magnetosphere or the core-crust boundary conditions. Our results mean that both Hall magnetohydrodynamics secular evolution and magnetospheric dynamical evolution are deeply affected by conditions of another region and the core-crust stress of magnetars.
National Priorities for Vocational Education.

National priorities exist that can be served through federal legislation for the funding of vocational education. Four alternatives that are examples of national needs that vocational education would appear to have a potential to address are (1) training and retraining of workers in national critical skill shortage occupations, (2) training and retraining of individuals in high technology areas, (3) training and retraining of displaced workers, and (4) improving employability of hard-to-employ youth in the inner cities and depressed rural areas. (The discussion of each area includes background information, implications, and federal and additional considerations.) Three alternative funding strategies could be used for directing federal vocational education dollars through state agencies towards national priorities; block grant, set-asides, and national incentives. Two additional funding strategies that represent a more significant departure from historic precedents are direct funding and directing a greater federal emphasis towards program improvement.

THE INVESTIGATION OF SOME MOHAIR MINERAL LEVELS (Mg, Fe, Cu, Zn) OF ANGORA GOATS IN ORIGINAL ZONE OF ANKARA PROVINCE

In this study, determination of some mineral levels of mohair samples obtained from Angora goats (Capra hircus ancyrensis) bred in villages of Basayas (1 farm, n=28 goats) and Yagmurdede (2 farm, n=30 goats) in Ankara province of Turkey was aimed. Totally 58 goats (2-4 years old) in two farms kept under similar managemental conditions and based on pasture were chosen as research materials. Mohair samples from mid-side of the goats were collected to determine the levels of magnesium (Mg), iron (Fe), copper (Cu) and zinc (Zn) by atomic absorption spectrophotometer (AAS) (M series V1, 23). The mohair mineral levels in the 1 and the 2 farm of Angoras were found as 22.234 ± 1.030 g/g and 20.952 ± 1.462 g/g for Mg; 37.716 ± 1.573 g/g and 32.271 ± 1.397 g/g for Fe (P<0.05); 4.248 ± 0.293 g/g and 7.169 ± 0.285 g/g for Cu (P<0.001); 60.673 ± 2.395 g/g and 62.802 ± 3.172 g/g for Zn, respectively. In the 1 and the 2 farm, nonsignificant positive and negative correlations between minerals were discovered. The estimated correlation coefficient between Fe and Cu was negative (r = 0.291) significant in total population (P<0.05).
Spin-orbital Tidal Dynamics and Tidal Heating in the TRAPPIST-1 Multiplanet System

We perform numerical simulations of the TRAPPIST-1 system of seven exoplanets orbiting a nearby M dwarf, starting with a previously suggested stable configuration. The long-term stability of this configuration is confirmed, but the motion of planets is found to be chaotic. The eccentricity values are found to vary within finite ranges. The rates of tidal dissipation and tidal evolution of orbits are estimated, assuming an Earth-like rheology for the planets. We find that under this assumption, the planets b, d, and e were captured in the 3:2 or higher spin–orbit resonances during the initial spin-down, but slipped further down into the 1:1 resonance. Depending on its rheology, the innermost planet b may be captured in a stable pseudosynchronous rotation. Nonsynchronous rotation ensures higher levels of tidal dissipation and internal heating. The positive feedback between the viscosity and the dissipation rate—and the ensuing runaway heating—are terminated by a few self-regulation processes. When the temperature is high and the viscosity is low enough, the planet spontaneously leaves the 3:2 resonance. Further heating is stopped either by passing the peak dissipation or by the emergence of partial melt in the mantle. In the post-solidus state, the tidal dissipation is limited to the levels supported by the heat transfer efficiency. The tides on the host star are unlikely to have had a significant dynamical impact. The tides on the synchronized inner planets tend to reduce these planets’ orbital eccentricity, possibly contributing thereby to the system’s stability.
