Biochemical composition of some green algae from Mandapam coast

Twenty three species of green algae belonging to twelve genera collected frsm Mandapam coast were analysed for protein, carbohydrate and lipid. The protein content varied from 5.06% (Codium tomentosum) to 20.93% (Microdictyon agardhianum). The carbohydrate content varied from 16.01 (Ulva lactuca) to 56.251 in (Caulerpa laetevirens). The lipid content ranged from 6.99% (Caulerpa sertularioides) to 15.701 (Cladophora fascicularis).
Comparison of the Effect of Passive and Active Recovery, and Self-Myofascial Release Exercises on Lactate Removal and Total Quality of Recovery

Recovery from exercise-induced fatigue is crucial for subsequent performance. Self-myofascial release (SMR) using a foam roller is an alternative to active recovery (AR). This study aims to compare the effects of passive recovery (PR), AR, and SMR on blood lactate [La-] removal and total quality of recovery (TQR). Twenty-two well trained male athletes (age: 22.6±2.9 years) underwent three testing sessions conducted 72 hours apart but at the same time of each day in a randomized order. After determining resting [La-] and heart rate (HR), the subjects completed a Wingate anaerobic test (WAnT), triggering muscular fatigue. HR and [La-] were measured threeminutes after the WAnT, following which the subjects underwent one of the three different recovery interventions over 15 minutes: PR (lying supine), AR (cycling at 40% of the estimated maximum HR of the respective subject), and SMR (using foam roller on lower extremity muscles). After each recovery intervention, [La-], HR, and TQR were measured. There was no statistically significant difference in [La-] and HR values obtained before the WAnT test (p=0.368, p=0.691, respectively) and right after the WAnT test (0.264, p=0.629) Both AR and SMR were more effective than PR for [La-] removal and obtaining a higher TQR (p<0.001). However, SMR and AR were not superior to one another for blood [La-] removal (p>0.05). In contrast, a significantly higher TQR was observed with SMR than AR and PR (p<0.001). Athletes can apply AR or SMR to recover from strenuous exercise. SMR can be an alternative to PR and AR as a recovery tool.
Empirical Assessment of Manufacturing Companies Efficiency in Nigeria:Data Envelopment Analysis (DEA) Approach

This study dwells on data envelopment analysis and industry analysis. The study analyzed the technical efficiency of twenty (20) selected manufacturing companies for the period 2015 to 2016 using input and output oriented data envelopment analysis (DEA) approach. Findings arising from the study indicate that 35% of the quoted sampled manufacturing firms in Nigeria were scale efficient while 65% were scale inefficient in the period observed. Thirty percent (30%) of the manufacturing companies on the basis of constant return to scale (CRS) were technically efficient while 70% of them were technically inefficient in the period observed. Forty percent (40%) of the companies in terms of variable return to scale (VRS) were technically efficient while 60% were not technically efficient in the context of variable return to scale. The study concluded that manufacturing firms in Nigeria are not optimally performing with input and output mix of variables. It is therefore recommended that there is need for them to scale down cost of production through appropriate strategic decisions. Keywords: Technical efficiency, data envelopment analysis, firm performance
The interplanetary magnetic structure that guides solar relativistic particles

Context. Relating in-situ measurements of relativistic solar particles to their parent activity in the corona requires understanding the magnetic structures that guide them from their acceleration site to the Earth. Relativistic particle events are observed at times of high solar activity, when transient magnetic structures such as interplanetary coronal mass ejections (ICMEs) often shape the interplanetary magnetic field (IMF). They may introduce interplanetary paths that are longer than nominal, and magnetic connections rooted far from the nominal Parker spiral. Aims. We present a detailed study of the IMF configurations during ten relativistic solar particle events of the 23rd activity cycle to elucidate the actual IMF configuration that guides the particles to the Earth, where they are measured by neutron monitors. Methods. We used magnetic field (MAG) and plasma parameter measurements (SWEPAM) from the ACE spacecraft and determined the interplanetary path lengths of energetic particles through a modified version of the velocity dispersion analysis based on energetic particle measurements with SoHO/ERNE. Results. We find that the majority (7/10) of the events is detected in the vicinity of an ICME. Their interplanetary path lengths are found to be longer (1.5–2.6 AU) than those of the two events propagating in the slow solar wind (1.3 AU). The longest apparent path length is found in an event within the fast solar wind, probably caused by enhanced pitch angle scattering. The derived path lengths imply that the first energetic and relativistic protons are released at the Sun at the same time as electron beam emitting type III radio bursts. Conclusions. The timing of the first high-energy particle arrival on Earth is mainly determined by the type of IMF in which the particles propagate. Initial arrival times are as expected from Parker’s model in the slow solar wind, and significantly longer in or near transient structures such as ICMEs.
Why does the spotted UX Ari system get bluer as it gets darker

We present simplified calculations of UX Ari B − V colour index and V magnitude for a range of parameter values. The results of our calculations are compared to previously published measurements. We find that our calculations reproduce the well established colour-brightness relation (UX Ari gets bluer as it gets darker) only if the dark spots on the surface of the K star are accompanied by bright facular areas. There is currently an ambiguity between the temperature of the facular areas and the portion of the stellar surface occupied by them.

A unifying phase diagram with correlation-driven superconductor-to-insulator transition for the 122 series of iron chalcogenides

The 122$^{*}$ series of iron-chalcogenide superconductors, for example K$_x$Fe$_{2-y}$Se$_{2}$, only possesses electron Fermi pockets. Their distinctive electronic structure challenges the picture built upon iron pnictide superconductors, where both electron and hole Fermi pockets coexist. However, partly due to the intrinsic phase separation in this family of compounds, many aspects of their behavior remain elusive. In particular, the evolution of the 122$^{*}$ series of iron-chalcogenides with chemical substitution still lacks a microscopic and unified interpretation. Using angle-resolved photoemission spectroscopy, we studied a major fraction of 122$^{*}$ iron-chalcogenides, including the isovalently `doped' K$_x$Fe$_{2-y}$Se$_{2-z}$S$_z$, Rb$_x$Fe$_{2-y}$Se$_{2-z}$Te$_z$ and (Tl,K)$_x$Fe$_{2-y}$Se$_{2-z}$S$_z$. We found that the bandwidths of the low energy Fe \textit{3d} bands in these materials depend on doping; and more crucially, as the bandwidth decreases, the ground state evolves from a metal to a superconductor, and eventually to an insulator, yet the Fermi surface in the metallic phases is unaffected by the isovalent dopants. Moreover, the correlation-driven insulator found here with small band filling may be a novel insulating phase. Our study shows that almost all the known 122$^{*}$-series iron chalcogenides can be understood {\it via} one unifying phase diagram which implies that moderate correlation strength is beneficial for the superconductivity.
American Psychologist, in press

Empirical evidence supports the efficacy of psychodynamic psychotherapy. Effect sizes for psychodynamic psychotherapy are as large as those reported for other therapies that have been actively promoted as “empirically supported” and “evidence based. ” Additionally, patients who receive psychodynamic therapy maintain therapeutic gains and appear to continue to improve after treatment ends. Finally, non-psychodynamic therapies may be effective in part because the more skilled practitioners utilize techniques that have long been central to psychodynamic theory and practice. The perception that psychodynamic approaches lack empirical support does not accord with available scientific evidence and may reflect selective dissemination of research findings.
VITALITY AND MORPHOLOGY OF TUMOR CELLS TREATED WITH

39 The development of new systems for delivery of the antineoplastic drugs with low toxicity, capability of addressed transportation of drugs to the tumor target cells, and visualization of their action in the body is one of the major problems in modern biopharmaceutics. Despite an intensive work on creation of new anticancer drugs, the problem of cancer treatment has not been solved. The main reasons for that are the development of tumor cell resistance to known and new chemotherapeutic drugs and general toxicity in the body, resulting in damage of cells of normal tissues and organs [1]. One of the main mechanisms underlying acquired resistance of tumor cells to cytotoxic anticancer drugs is cell membrane transport that ensures removal of various xenobiotics, including drugs, from the target cells. This phenomenon has been called a multi-drug resistance (MDR) [2]. Therefore, synthesis of new substances capable of killing cells resistant to anti-tumor drugs, and using special systems for delivery of these drugs are the priorities of the biopharmacology. The biocompatible and biodegradable polymers forming nanoscale particles possess high stability in the body, low toxicity and, because of their unique chemical structure, can be further functionalized in order to provide addressed delivery of the immobilized drugs to specific target cells and biomolecules. The use of these nanoscale systems can significantly reduce the effective therapeutic dose of the applied anticancer drug. A number of synthetic polymers which can significantly enhance the biological effects of anticancer drugs in vitro and in vivo were described [3, 4].

Do Flexible Employment Contracts Change Household Income Differences in Italy

This paper examines whether the growing use of non-permanent contracts may have inuenced the intra-family income differences in Italy over time. After the 1996, a number of reforms were imple- mented to reduce the levels of employment protection. Thus we aim at providing evidence on the determinants of potential changes to per- sonal level of income before and after the introduction of such rules. In particular, we calculate the contribution of each individual within the family using two Italian longitudinal data (namely ECHP and IT- Silc). We perform estimations for men and women, separately. Our results confirm that the amount of contribution changes over the span considered. Fathers are generally more likely to support other family members. Sons are instead money receivers, and the magnitude of the coefficient is especially large when labour market fexibility has been already introduced. Individuals with part time temporary contracts face less favourable financial conditions. Finally, those who are out of the labour market (i.e. retired, unemployed, inactive) contribute negatively within the family.
EFFECT OF DIFFERENT pH LEVELS ON THE GROWTH AND SPORULATION OF FUSARIUM OXYSPORUM SCHLECHT. F. SP. LENTIS (VASUDEVA AND SRINIVASAN) THE CAUSAL ORGANISM OF WILT DISEASE OF LENTIL

Effect of pH on the growth and sporulation of Fusarium oxysporum Schlecht . f . sp. lentis (Vasudeva and Srinivansan) after incubation of two weeks in vitro culture in sucrose nitrate medium was studied. pH level 6.0 was found optimum for the growth as well as sporulation of the fungus. Sporulation of chlamydospore was however found best in the pH level 4.0. Further increases in the pH level show retarding effect on growth and sporulation. Size of the spores increases with increase in the pH range.
The Analyses of Causality Relationships for Service Brands Development

The globally intensive competition of the business environment has forced the service corporations to gain the trust customer relationship. Developing the service brands and effective management will achieve the customer trust and intimate customer relationship. How to successfully build the service brands is a critical issue for the service industries. In this research, we want to examine the core capability of the brand development for service organizations. Based on the literature review and experts interviews, we can develop an integrated model, which is constituted by five constructs: business model, brand development, service quality, customer value, and business performance. Based on the integrated model, a structure equation model (SEM) can be proposed, which is used for the causality analyses for service firms to build their owned brand, and then we conduct the related empirical study. Based on the statistic analyses, the causalities among the constructs of SEM model can be confirmed. 'Business model' is the fundamental force for the brand development, which can result in better 'customer value' and then the 'business performance', especially the financial performance. Besides the brand marketing, the service firms need to realize the practices of quality management and customer relation management.
No effect of partner age and lifespan on female age‐specific reproductive performance in blue tits

Studies of age-specific reproductive performance are fundamental to our understanding of population dynamics and the evolution of life-history strategies. In species with bi-parental care, reproductive ageing trajectories of either parent may be influenced by their partner's age, but this has rarely been investigated. We investigated within-individual age-specific performance (laying date and number of eggs laid) in wild female blue tits Cyanistes caeruleus and evaluated how the age and longevity of their male partner indirectly influenced the females' reproductive performance. Females showed clear age-dependence in both laying date and number of eggs laid. We found that female reproductive performance improved in early life, before showing a decline. Longer-lived females had an earlier laying date throughout their lives than shorter-lived females, but there was no difference in number of eggs laid between longer- and shorter-lived females. Within breeding pairs, the female's (age-specific) reproductive performance was not dependent on the age and longevity of the male partner. We conclude that the age and quality of the male partner may be of little importance for traits that are under direct female control. This article is protected by copyright. All rights reserved.
Determinants of perceived job security

A lot of employees suffer from low perceived job security that affects health but also performance during work. Due to this fact, the aim of this research is to figure out which factors influence this perceived job security. These factors could be used to enhance perceived job security and provide a possibility to improve the performance during work. In this research five determinants were chosen for examination in that regard, namely self-efficacy, trust, task-oriented leadership, relationship-oriented leadership and organizational identification. Additionally, the interaction effects between these determinants in regard to perceived job security were examined. To do so, 120 employees were asked to fill in an online survey with 51 items in total. The results show that all examined determinants positively correlate with perceived job security. However, a regression analysis shows that none of the observed determinants is a predictor for perceived job security. Also there are no interaction effects between the determinants affecting perceived job security. In regard to these findings, this research additionally introduces new scientific issues concerning the explanation of the correlations and delivers possible ways of how to elaborate these.
Carbonate and organic carbon cycles in Aptian- Albian black shales at Deep Sea Drilling Project Site 511, Falkland Plateau.

Thin but discrete pelagic limestone beds intercalated among the black mudstones near the top of the extensive Mesozoic black shale sequence of the Falkland Plateau are reminiscent of similar occurrences in the central and North Atlantic and may be cyclic in nature. They have been studied via carbonate, organic carbon, stable isotope, nannofloral, and ultrastructural analysis in an attempt to determine their mode of origin. Nannofossil diversity and preservation suggest that selective dissolution or diagenesis did not produce the interbedded coccolith-rich and coccolith-poor layers, nor did blooms of opportunistic species play a role. Stable isotope measurements of carbonate do not adequately constrain the origin of the cyclicity; however, the δC data suggest that the more nannofossil-rich intervals may be due to higher nutrient supply and overturn of deeper waters at the site rather than influxes of well-oxygenated waters into an otherwise anoxic environment. Such an explanation is in accord with the nannofloral evidence.
Estimating relative risk for dengue disease in Peninsular Malaysia using INLA

Study in spatio-temporal disease mapping models give a great worth in epidemiology, in describing the pattern of disease incidence across geographical space and time. This paper studies generalized linear mixed models (GLMM) for the analysis of spatial and temporal variability of dengue disease rates. For spatio-temporal study, the models accommodate spatially correlated random effects as well as temporal effects together with the space time interaction. The space time interaction is used to capture any additional effects that are not explained by the main factors of space and time. However, as study including time dimension is quite complex for disease mapping, the temporal effects that only relate to structured and unstructured time pattern are considered in these models as initial screening in studying disease pattern and time trend. The models are fitted within a hierarchical Bayesian framework using Integrated Nested Laplace Approximation (INLA) methodology. For this study, there are three main objectives. First, to choose the best model that represent the disease phenomenon. Second, to estimate the relative risk of disease based on the model selected and lastly, to visualize the risk spatial pattern and temporal trend using graphical representation. The models are applied to monthly dengue fever data in Peninsular Malaysia reported to Ministry of Health Malaysia for year 2015 by district level.
INFLUENCE OF SOLID MOISTURE AND BED HEIGHT ON CULTIVATION OF Aspergillus niger FROM SUGARCANE BAGASSE WITH VINASSE

Solid-state cultivation (SSC) may be defined as growth of microorganisms on a solid support impregnated or not with a nutrient solution in near absence of free-water conditions. The use of sugarcane bagasse as a support for SSC usually demands that the particles are impregnated and moistened with nutrient solution. Vinasse is the main wastewater of ethanol fermentation-distillation. As there are no reports of the use of wastewater for moistening solid supports in SSC, the proposal is the development of an innovative process, with valuation of these by-products. Thus, the aim of this research was to evaluate SSC of Aspergillus niger using sugarcane bagasse and vinasse for citric acid production. The results indicate that citric acid production and glucose consumption are dependent on oxygen availability, which can be modulated by selection of bed height and air-flow in packed-bed bioreactors.
A multivariate rank test of independence based on a multiparametric polynomial copula

This paper introduces a copula based multivariate rank test for independence extending existing approaches from literature to p dimensions. Then, a multiparametric p-dimensional generalization of the FGM copula is provided that can model the behavior in each vertex of the p-dimensional unit cube using exactly one parameter per vertex - the family of polynomial copulas. The independence copula is nested in this family if and only if every parameter is zero. In this case, a popular way to test for independence is comparing an estimate of the vector of parameters to a vector containing zeros only. Unfortunately, due to the mere quantity of parameters, no established estimation procedure can be used in higher dimensions. Instead, the developed multivariate rank test is applied sequentially to every parameter to test for joint squared deviation from independence. Applying this new test to the polynomial copula results in the new vertex test which is a test for independence with focus on the high dimensional tail regions. It is compared to similar nonparametric rank tests of independence by means of calculation time and power under several alternatives and sample sizes.
Deformation studies at Furnas and Sete Cidades Volcanoes (São Miguel Island, Azores). Velocities and further investigations

SUMMARY The Azores archipelago is located near the triple junction between the Nubian (NU), North America (NA), and Eurasia (EU) plates. It is characterized by a relatively strong seismicity and active volcanism. The best estimate of the current plate velocities in the area over geologic timescales comes from the NUVEL1-NNR model (DeMets et al.) . At the geodetic timescale, plate motion models (Altamimi et al., Sella et al.) including GPS, DORIS, SLR and VLBI data currently do not yet include data from the Azores. In the framework of a research project focused on the seismotectonics and volcanotectonics of Sao Miguel island, we have analysed GPS data collected there in 1993, 1994, 1997, 2000 and 2002. Our analysis determines both the velocity in the REVEL (Sella et al.) reference frame of Sao Miguel and its internal deformation. The comparison of the 2000 and 2002 coordinates indicates that Sao Miguel accommodates moderate WNW-ESE extension at a rate slower than 5 mm yr −1 .
