Multilevel Analysis of the Bacterial Diversity along the Environmental Gradient Río de la Plata–South Atlantic Ocean

The Rio de la Plata is the world's largest estuary, draining the second largest basin of South America. In spite of its key significance at the local and global scale, this is the first attempt made so far to characterize the bacterial diversity of this system. We employed a suite of molecular methods to analyze the bacterial diversity at different phylogenetic levels, both in terms of richness and evenness, and we related these findings to physicochemical parameters. A clear environmental gradient was observed with 3 distinctive zones (riverine, frontal, and marine). In turn, the bacterial communities appeared highly diverse and strongly structured by the environment. A high number (324) of different operational taxonomic units (OTUs) were identified by automated ribosomal inter- genic spacer analysis (ARISA). The ARISA results suggested that the composition of bacterioplank- ton communities was strongly related to physicochemical water characteristics, and that the bacterio- plankton had little overlap with the bacterial assemblage of the sediments. Catalyzed reporter deposition-fluorescence in situ hybridization (CARD-FISH) indicated that Betaproteobacteria and Actinobacteria were more abundant in the riverine zone, whereas Gammaproteobacteria and Planc- tomycetes preferred the marine waters. The relative abundance of Bacteroidetes peaked in the frontal zone, and Alphaproteobacteria were numerically dominant throughout the estuary. The analysis of about 300 almost full-length 16S rRNA gene sequences pointed to the existence of ubiq- uitous phylotypes, but also suggested habitat preferences among certain groups. This first look into the bacterial community of the Rio de la Plata demonstrated marked diversity patterns, providing fur- ther insights into the ecology of globally distributed groups of aquatic bacteria.
Some Problems with Application of Change-Point Detection Methods to Environmental Data

This paper summarizes the author's experience in researching methods of discovering a change in the behaviour of meteorological and hydrological series. Basic statistical tests applying 'maximum' type statistics to detect a sudden or gradual change in location are given. The author stresses that the characteristic properties of the meteorological and hydrological data, especially the dependence between neighbouring observations, have to be considered by performing statistcal tests for change-point detection.
Dynamical mean-field theory study of stripe order and d -wave superconductivity in the two-dimensional Hubbard model

We use cellular dynamical mean-field theory with extended unit cells to study the ground state of the two-dimensional repulsive Hubbard model at finite doping. We calculate the energy of states with d-wave superconductivity coexisting with spatially uniform magnetic order and find that they are energetically favoured in a large doping region as compared to the uniform solution. We study the spatial form of the superconducting and magnetic order parameters at different doping values.
Forecasting euro area variables with German pre-EMU data

It is investigated whether Euro-area variables can be forecast better based on synthetic time series for the pre-Euro period or by using just data from Germany for the pre-Euro period. Our forecast comparison is based on quarterly data for the period 1970Q1 - 2003Q4 for ten macroeconomic variables. The years 2000 - 2003 are used as forecasting period. A range of different univariate forecasting methods is applied. Some of them are based on linear autoregressive models and we also use some nonlinear or time-varying coefficient models. It turns out that most variables which have a similar level for Germany and the Euro-area such as prices can be better predicted based on German data while aggregated European data are preferable for forecasting variables which need considerable adjustments in their levels when joining German and EMU data. These results suggest that for variables which have a similar level for Germany and the Euro-area it may be reasonable to consider the German pre-EMU data for studying economic problems in the Euro-area.
Expanding the Acculturation Gap-Distress Model: An Integrative Review of Research

The acculturation gap-distress model purports that immigrant children acculturate to their new culture at a quicker pace than their parents, leading to family conflict and youth maladjustment. This article reviews literature on the acculturation gap-distress model, showing that acculturation gaps function in unique ways depending on many social and contextual variables. In contrast to the original model, which only discusses 1 type of acculturation gap, there are at least 4 types of acculturation gaps: (1) the child is more acculturated than the parent in the host culture, (2) the child is less acculturated than the parent in the host culture, (3) the child is more acculturated than the parent in the native culture, and (4) the child is less acculturated than the parent in the native culture. A review of research indicates that each of these types of gaps function in unique ways.
Safety Evaluation of Absorbent Hygiene Pads: A Review on Assessment Framework and Test Methods

Disposable absorbent hygiene products have evolved for superior performance, enhancing the convenience of daily lives. However, the use of disposable hygiene pads has brought safety concerns on chemical exposure, and significant efforts have been made to assess the potential risks associated with use of hygiene pads. This article intends to overview the safety assessment framework of diapers and feminine pads, which includes hazard identification, hazard characterization, exposure assessment, risk characterization, and post-market risk management. Risk assessment of various constituents are reviewed for quantification methods and conservative estimation of exposure parameters. By reviewing the up-to-date considerations in risk assessment, we aim to provide insightful discussion on safety evaluation of current versions of disposable absorbent products. More clinical testing and post-market surveillance are needed for continuous monitoring of potential health impacts of advanced products and constituents.
Potentiometric Determination of Enrofloxacin Using PVC and Coated Graphite Sensors

Modern ion selective electrodes are based on membranes, across which material transport occurs, this material transport, includes both neutral and charged complex species or simple ions and electrons and leads to electrostatic potential differences across membranes. These so, called membrane potentials reflect both composition and activities of ions in the exterior phase. The ion-selective electrode is capable of measuring selectivity and activity of a given ion regardless of other ions present in solution [1-4].
Authoritative parenting and college students' academic adjustment and success.

This study examined connections between college students' adjustment and success and characteristics of their relationships with their parents. A sample of 236 students completed the Student Attitudes and Perceptions Survey, a 135-item anonymous self-report instrument. Students' grades, confidence level, persistence, task involvement, and rapport with their teachers were generally predicted by both current and childhood levels of parental autonomy granting, demandingness, and supportiveness. Ratings of parenting characteristics were equally predictive of adjustment and success among students living with their parents and those living on their own. They were somewhat less predictive of seniors' adjustment and success than they were for freshmen, sophomores, and juniors. These findings suggest that parenting style continues to play an important role in the academic lives of college students.
Stabilized rice bran extract: Acute and 28-day repeated dose oral toxicity with in vitro mutagenicity and genotoxicity study

The toxicity of Egyptian stabilized rice bran extract (RBE) has been evaluated for acute and repeated 28 day oral toxicity with the outcome of genotoxicity. The extract was administered to female white albino rats at 2000 mg kg-1 for acute testing and to male and female rats at concentrations of 1000, 500, and 100 mg kg-1 for 28 days. Mutagenic potential was evaluated. Chromosomal and DNA damage using standard karyotyping and alkaline comet assay were applied. Acute study showed neither deaths nor gross of pathological abnormalities. In 28 days study, no dose-related changes were observed in body weights, haematological as well as the majority of the serum biochemistry parameters. Results showed neither mutagenic nor genotoxic effects of the RBE. Histological findings showed significant changes in rat groups administering 1000 and 500 mg kg-1 doses. The extract proved to be non toxic acutely and the degree of toxicity was noticed to be dose dependent after chronic administration. Thus we suggest that RBE at dose of 100 mg kg-1 (equivalent to 1 g oil daily consumption) is safe to be administered as dietary supplement for long term use. Key words: Stabilized rice bran oil extract (RBE), ames test, alkaline comet assay, chromosomal aberrations, white albino rats.
Customer Challenges in Times of Global Risk and Uncertainty

Rapidly changing business conditions have made it more difficult and challenging for managers to keep customers (Carter, 2008). To build this process it is necessary to consult customers for preferences, build familiarity and knowledge to build a relationship and conduct business in a customized fashion. The process takes every opportunity to build customer satisfaction with each customer contact. It is an important process to have, since customers today are more demanding, sophisticated, educated and comfortable speaking to the company as an equal (Belk, 2003). Customers have more customized expectations so they want to be reached as individuals (Raymond and Tanner, 1994). Also, a disproportionate search for new business is costly. The cost to cultivate new customers is more than maintaining existing customers (Cathcart, 1990). Other reasons that Customer Retention is necessary is because many unhappy customers will never buy again from a company that dissatisfied them and they will communicate their displeasure to other people. These dissatisfied customers may not even convey their displeasure but without saying anything just stop doing business with that company, which may keep them unaware for some time that there is any problem (Cathcart, 1990).

Antioxidant Activity of Curcumin and Neem (Azadirachta indica) Powders: Combination Studies with ALA Using MCF-7 Breast Cancer Cells

Introduction: Breast cancer is the most common cancer affecting women globally. The essential fatty acid α-Linolenic acid (ALA) and its oxidation products inhibit cancer cell proliferation. The effect of natural antioxidants on ALA anticancer effects has not been well characterized. Aims: To assess the effect of curcumin and neem leaf powder extract, on ALA cytotoxicity activity towards MCF-7 breast cancers.Study Design: In-vitro testing.Methodology: Antioxidant activity of neem extract and curcumin were evaluated using, four assays: Total phenolic content, Ferric reducing antioxidant power (FRAP), 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay or 2, 2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) assay. Cytotoxicity activity was assessed using MCF7 cells grown in DMEM (+10% FBS) and evaluated using Sulforhodamine B colorimetric assay for cell cytotoxicity.Results: Curcumin and neem leaf extract had significant antioxidant power, and values varied between the four assays. Treatments of MCF7 cells with ALA, (0-500 µM) curcumin (0-50 µM), and neem leaf extract (0-88 µM) individually produced a concentration-dependent decrease in MCF-7 cell viability. Combination treatments using ALA with curcumin and ALA with neem were significantly less effective compared to individual treatments.Conclusion: Combinations studies indicate that the natural antioxidants curcumin and neem reduce the inhibitory effect of α-Linolenic acid towards MCF-7 breast cancer cells.
LONGITUDINAL COUPLING IMPEDANCE OF A STATIONARY ELECTRON RING IN A CYLINDRICAL GEOMETRY.

The longitudinal (azimuthal) coupling impedance is investigated for a stationary electron-ring beam circulating between a co-axial pair of conducting tubes. Proximity of the beam to the inner tube is found to be advantageous for reducing (I ZII I/n)max. Similar results are shown to be attainable with operation near the the outer tube, provided the quality factors 'Q for higher-order resonant modes are deliberately made small. Illustrative computational results are presented graphically and a convenient approximate formula is suggested that may serve to guide the selection of desirable parameters for a typical fully-compressed electron ring.
Correlation Analysis of Grain Yield and Important Agronomic Traits in Six Rowed Barley ( HORDEUM VULGARE L . ) in Agra Region

The investigation was conducted to evaluate the genotypic and phenotypic correlation analysis of grain yield and other contributing traits of cultivars and breeding line of barley in K.V. K. Research Farm Mathura. The results of correlation coefficient revealed thatthe genotypic correlations in general were higher than phenotypic correlations.The seed yield expressed significant and positive correlation at genotypic and phenotypic levels with tillers per plant (r= 0.382G, r= 0.358P), seeds per spike (r= 0.583G, r= 0.519P), 1000 seed weight (r= 0.364G, r=0.297P), biological yield per plant (r= 0.921G, r= 0.862P) and harvest index (r= 0.498G, r= 0.439P). Seed yield exhibited positive but non-significant association with days to flower (r= 0.058G, r= 0.029P) and strongly significant negative association with days to maturity (r= -0.634G, r= -0.487P) and plant height (r= -0.083G, r= -0.075P).
Novel Switching Table for Direct Torque Controlled Permanent Magnet Synchronous Motors to Reduce Torque Ripple

The Direct Torque Control (DTC) technique for Permanent Magnet Synchronous Motors (PMSM) is receiving increased attention due to its simplicity and robust dynamic response when compared with other control techniques. The classical switching table based DTC results in large flux and torque ripples in the motors. Several studies have been reported in the literature on classical DTC. However, there are only limited studies that actually discuss or evaluate the classical DTC. This paper proposes, novel switching table / DTC methods for PMSMs to reduce torque ripples. In this paper, two DTC schemes are proposed. The six sector and twelve sector methodology is considered in DTC scheme I and DTC scheme II, respectively. In both DTC schemes a simple modification is made to the classical DTC structure. The two level inverter available in the classical DTC is eliminated by replacing it with a three level Neutral Point Clamped (NPC) inverter. To further improve the performance of the proposed DTC scheme I, the available 27 voltage vectors are allowed to form different groups of voltage vectors such as Large - Zero (LZ), Medium - Zero (MZ) and Small - Zero (SZ), where as in DTC scheme II, all of the voltage vectors are considered to form a switching table. Based on these groups, a novel switching table is proposed. The proposed DTC schemes are comparatively investigated with the classical DTC and existing literatures through theory analysis and computer simulations. The superiority of the proposed DTC method is also confirmed by experimental results. It can be observed that the proposed techniques can significantly reduces the torque ripples and improves the quality of current waveform when compared with traditional and existing methods.
Beyond the Decade of Policy and Community Euphoria: The State of Livelihoods Under New Local Rights to Forest in Rural Cameroon

This paper interrogates the state of livelihoods under the exercise of new community rights to forest in rural Cameroon. The assessment makes use of a set of livelihoods indicators. The granting and exercise of new community rights, namely, management rights and market rights, are not synonymous with improved livelihoods, despite initial predictions and expectations. The resource base has not changed; it is more and more threatened by poor local level institutional arrangements and social and bio-physical management strategies, in addition to the weak central level regulation and monitoring actions. Similarly, the rights-based reform and community forestry are not improving basic assets and means at the household level. Nevertheless, this paper suggests that this experiment should not be judged hastily, since fifteen years are not enough to judge social and institutional processes like those in progress in Cameroon. The authors draw policy options likely to improve the livelihoods dimension of the reform and launch a debate on the real contribution of community income derived from community forests towards poverty alleviation at the household level.
Social Exclusion and Social Work: Questions for the Future

This special edition brings together a diverse group of contributors with a shared focus. The edition seeks to explore dimensions of social exclusion in the context of social work practice, education and learning. The articles and book reviews address this theme in different ways, but in so doing raise interesting questions for the development of social work education and practice. This introductory article describes our theoretical approach to social exclusion and considers the changing nature of social work in this context. We identify some of the questions raised by the contributors and conclude by describing what we see as the complex and challenging issues that social work must face when addressing exclusionary processes. We recognise that social exclusion is a contested concept but, as set out below, we suggest that it offers a useful means by which the lived experiences of those needing or using social work services can be understood and addressed.

Vertical distribution of fish biomass in hypoxic waters on the Gulf of Mexico shelf

Hypoxic bottom waters (dissolved oxygen ≤2.0 mg l -1 ) in the northwestern Gulf of Mexico are largely due to nutrient loading from the Mississippi-Atchafalaya watershed. Loss of ben- thic habitat has been documented in bottom trawl surveys, but little is known about the effect of hypoxia on the vertical distribution of fish biomass. To investigate these effects, we used a 120 kHz split-beam echosounder to compare the vertical distribution of fish biomass at stations with hypoxic bottom waters to those with normoxic bottom waters. We also used paired mongoose and flat trawls to assess species composition, and a CTD to measure physical characteristics of the water column. Atlantic croaker Micropogonias undulatus, Atlantic bumper Chloroscombrus chrysurus, and anchovies (Anchoa spp.) comprised 92% (by number) of fish sampled. Dissolved oxygen, time of day, and depth within the water column were the major factors explaining variation in acoustic biomass. Stations inside and outside of the hypoxic zone had similar overall density but differed in vertical dis- tribution. Hypoxic stations had greater biomass in the upper 7 m of the water column and much less biomass below 13 m compared to normoxic stations, consistent with aggregation of organisms above the bottom hypoxic layer. We did not find evidence of strong aggregation at the hypoxic edge throughout the entire water column. While the pelagic habitat is not directly impacted by low- oxygenated bottom water, hypoxia can induce vertical or horizontal displacement of fish mediating potential indirect bioenergetic or trophic interactions.
