β-carotene in sunflower oil oxidation

The oxidation kinetics of sunflower oil (SO), as well as of pure triacylglycerols of sunflower oil (TGSO) in the presence of different concentrations (0.001-0.02 %) β-carotene was studied. The process was performed at high (kinetic regime) and low (diffusion regime) oxygen concentrations at room temperature in the dark and under daylight. The results from the oxidation of SO and TGSO at 100oC in the presence of β-carotene were also presented. It was established that in the antioxidant-free lipid system, the β-carotene did not give any antioxidative protection. It worked as a prooxidant during the oxidation at room temperature and at sufficiently high oxygen concentration, the effect being more pronounced in the dark than under daylight. β-carotene increased the stability of tocopherol-containing SO during its oxidation at room temperature and under daylight. This effect is more strongly expressed in a kinetic regime of oxidation. The synergism of β-carotene with the tocopherols was characterized by the stabilization factor F and the activity A. In the kinetic regime of oxidation F and A varied in the interval F=2.0-6.3, and A =2.7-21.0. In the diffusion regime F=1.3-1.5, and A=1.5-2.8.
Can incentive-based spatial management work in the Eastern tuna and billfish fishery?

The Eastern tuna and billfish fishery (ETBF) is currently managed through an input quota system based on individual transferable effort units (the number of hooks) and a total allowable effort level (i.e. total number of hooks) A spatial management policy based on a series of differential hook-penalties has been proposed as a flexible tool to discourage vessels operating in certain areas (e.g. those with high bycatch potential) and encourage operating in other areas (e.g. with less bycatch potential). In this study, the importance of catch rates per hook to location choice is assessed through the estimation of a nested multinomial logit model. Other variables in the model include distance to the location, prices of the main species, fuel prices and vessel characteristics. The effects of increasing hook penalties in key areas on fishing effort in those areas and elsewhere are assessed. Implications for vessel economic performance are also assessed.
Microalgae Cultivation for Lipids and Carbohydrates Production

Microalgae are photoautotrophic microorganisms that can produce energy both by using sunlight, water and CO2 (phototrophic metabolism) and by using organic sources such as glucose (heterotrophic metabolism). Heterotrophic growth is a key factor in microalgae research, due to its increased productivity and the lower capital and operative costs compared to photoautotrophic growth in photobioreactors. Carbohydrate production from microalgae is usually investigated for the production of biofuels (e.g. bioethanol) by successive fermentation, but also other applications can be envisaged in biopolymers. In this work an increment in carbohydrate purity after lipid extraction was found. Protein hydrolysis for different microalgae strains (Scenedesmus sp. and Chlorella sp.) was investigated. Microalgae were cultivated under photoautotrophic or heterotrophic conditions, collecting biomass at the end of the growth. Biomass samples were dried or freeze dried and used for carbohydrate and lipid extraction tests. Lipid extraction was achieved using different organic solvents (methanol-chloroform and hexane-2propanol). Basic protein hydrolysis has been carried out testing different temperatures and NaOH concentrations values. Lipids were spectrophotometrically quantified, while residual biomass was saccharificated and the total amount of sugars was measured. Significant differences about the purity of extracted carbohydrates were found comparing dried with freeze dried biomass. However, not a very promising purification of carbohydrates was achieved after protein hydrolysis, asking for further analysis.
Walking Behaviour and Spatial Use of Broiler Chickens

Modern broiler chickens are genetically selected for reaching higher weights in shorter life spans. In addition to this, they are raised in crowded housing conditions with less opportunity for movement. Understanding movement patterns, migration and use of space is essential in determining welfare of the birds in commercial farms. In this study, migration behaviour of broiler chickens in semi-commercial farms of 1800 chickens was studied. Observations were repeated in six growth periods each on 12 chickens once a day during their growth period of 42 days. It was seen that the activity of broilers was not decreasing during the growth period. Travelled distances of the chickens in total were not reduced in the last 3 weeks of their growth period (p > 0.05 in 89% of the observed birds, Mann-Whitney U test). Chickens preferred to be in the zones next to the wall farthest to the entrance of the house. The observed birds did not restrict themselves only around the feeders and the drinkers but used the whole surface area available during the whole growth period. The results of the study seem to be encouraging in achieving welfare of broiler chickens even in commercialised houses with high stocking density. Reported mobility of chickens is important for their survival and has therefore considerable impact on efficient production on farms.
Dividend Policy and Share Price Volatility: Evidence from Pakistan

The main purpose of this study is to examine the relationship between dividend policy and share price volatility in Pakistani stock market. The cross sectional regression is used to analyze the relationship of share price with dividend yield and payout ratio. The dividend yield and share prices are positively relate but payout ratio is negatively related. This study suggest that dividend policy is effect the share price volatility in Pakistan and this study also proposed that signaling effect is also relevant in determining the share price volatility.
Surgical management of proximal humerus fracture treated with locking compression plate

Background: Proximal humerus fractures accounts for about 4 to 5% of all fractures. Treatment of unstable, displaced, and comminuted fractures of the proximal humerus remain challenging. Significant controversy continues regarding the best methods of treating displaced proximal humerus fractures. Various operative procedures are carried out, the recent trend in internal fixation has moved on to locking plates. The present study is undertaken to evaluate the functional outcome and complication of proximal humerus fractures treated by locking compression plate. Methods: This is a prospective study comprising of 30 patients with fractures of proximal humerus were treated by open reduction and internal fixation with locking compression plate were evaluated at Velammal Institute Of Medical Sciences, Madurai from the period of April 2015 to December 2016. Clinical and radiological evaluation was done. Patients will undergo open reduction internal fixation with locking compression plate for the sustained fracture under general anesthesia. Results: In our series, the majority of the patients were males, elderly aged, with RTA being the commonest mode of injury, involving 2 part, 3 part and 4 part fractures of the proximal humerus. Excellent and satisfactory results were found in 76.7% of patients with unsatisfactory results in 23.3 % according to Neer’s criteria. There were 100 % union rates and no failures. Conclusions: In conclusion locking Compression, the plate is an advantageous implant in proximal humeral fractures due to angular stability, particularly in comminuted fractures and in Osteoporotic bones in elderly patients, thus allowing early mobilization.
Interaction Mechanisms of Edge Dislocations with Obstacles in Fe and Metal Alloys

The need for energy and electricity in the modern society places large interest in producing power in more efficient and environmentally friendly ways. Almost all new energy production concepts also need new or improved materials, in particular, to prolong the lifetime of current nuclear power plants as well as build better, future GenIV fission concepts and fusion power plants. Hence the need to thoroughly understand the structural materials involved is inevitable. Current and future power plants are, and will be, built from some kinds of steel, which has shown very good properties and has become even better by informed choices of alloying elements and manufacturing techniques. Other fields also use steels that, for instance, show lower corrosion or higher tensile strength. The trend indicates that the steels used today can further be improved. Conventionally, these kinds of improvements have been studied by experiments on the possible materials, but recently, due to improved computational power, computer simulations have become an important part in the search for new structural materials. The key factor behind the mechanical properties of steel is known to be the movement of dislocations. If the dislocations are free to move, the material is generally ductile, but if the movement is hindered, the material will become more brittle. Previous studies have focused on how dislocation loops, voids and He bubbles will affect the movement of dislocations. All these defects are known to be formed during continuous irradiation of the materials, which is relevant for fission and fusion power plants. However, the effect of small non-coherent obstacles has received much less attention, even though these exist in ODS-steels and may also be a product of irradiation. One reason can be the lack of interaction models for these more complex systems. To address the lack of data on this phenomena, we focus in this thesis on how the movement of edge dislocations is affected by strong non-coherent obstacles. To model these, we investigated different carbides, which are known to be found in steels. A wide range of carbides of different shapes are investigated and compared to other defects, to assess their effect in relation to each other.
On the Current and Restoration Conditions of the Southern Iraqi Marshes: Application of the CCME WQI on East Hammar Marsh

Water quality of the East Hammar marsh after restoration was assessed by using the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI). The model was applied in two approaches based on the historical data and the CCME aquatic life guidelines as objectives. Variables included in the index calculation were Water Temperature, Dissolved Oxygen, Salinity, pH value, Total Nitrogen, Ammonia, Nitrate, Phosphorus and Sodium. The CCME WQI analysis in both approaches reflected that water quality of the East Hammar marsh is rated as poor based on 2005-2006 data, meaning that the conditions of the marsh are often depart from natural or desirable levels particularly in respect to sodium and nitrogenous compounds; it simply has not recovered yet. The results reflect that the marsh area is still far from the current guideline criteria and, too far from restoration.
Combining phase field approach and homogenization methods for modelling phase transformation in elastoplastic media

A general constitutive framework is proposed to incorporate linear and nonlinear mechanical behaviour laws into a standard phase field model. In the diffuse interface region where both phases coexist, two mixture rules for strain and stress are introduced, which are based on the Voigt/Taylor and Reuss/Sachs well-known homogenization schemes and compared to the commonly used mixture rules in phase field models. Finite element calculations have been performed considering an elastoplastic precipitate growing in an elastic matrix in order to investigate the plastic accommodation processes.
In‐cloud variability of LIDAR depolarization of polar and midlatitude cirrus

LIDAR depolarization is commonly used for discriminating liquid and ice particles. Since depolarization depends in a complicated manner on particle shape and size, in‐cloud variability of depolarization has been used as an indicator of the microphysical homogeneity of cirrus. The comparison between midlatitude (Florence, Italy, 43. 60°N) and polar (Dumont d'Urville, Antarctica, 66. 68°S) cirrus showed a lower mean depolarization and a higher in‐cloud uniformity of cloud depolarization for polar clouds in the (−80, −50°C) temperature range. A wider in‐cloud variability of depolarization was observed in polar clouds at higher temperatures (−50, −30°C), reflecting the presence of supercooled liquid layers. The large in‐cloud variability of depolarization in Florence cirrus could be explained with a microphysics that is dynamically and chemically perturbed as compared with the polar site. Aged jet contrails are, in fact, present in many Florence cirrus records.
Mortgage Lending and the Great moderation: a multivariate GARCH Approach

Financial innovation during the Great Moderation increased the size and scope of credit flows in the US. Credit flows increased both in volume and with regard to the range of activities and investments that was debt-financed. This may have contributed to the reduction in output volatility that was the Great Moderation. We hypothesize that during the Great Moderation (i) growth in mortgage finance partly decoupled from fundamentals as measured by overall output growth and (ii) this allowed mortgages less to finance residential investment and more to finance spending on other GDP components. We document that the start of the Moderation coincided with a surge in bank credit creation (especially mortgage credit), a rise in property income, a rise in the consumption share of GDP, and a change in correlation (from positive to negative) between consumption and non-consumption GDP components (investment, export and government expenditure). In a multivariate GARCH framework, we observe unidirectional causality in variance from total output to mortgage lending before the Great Moderation, which is no longer detectable during the Great Moderation. We also find that bidirectional causality in variance of home mortgage lending and residential investment existed before, but not during the Great Moderation. Both these findings are consistent with a role for credit dynamics in explaining the Great Moderation.
Antiplasmodial and Biochemical Effects of Combination of Ethanolic Leave-extracts of Azadirachta indica and Ocimum gratissimum on Plasmodium berghei-infected Mice

Malaria is an infectious disease that continues to be linked with considerable morbidity and mortality. The present study was to compare antimalarial activities of Azadirachta indica and Ocimum gratissimum as well as to evaluate the combined effect of the combination on Plasmodium berghei -infected mice. Curative effects against established infection were studied in chloroquine-sensitive P. berghei NK65-infected mice using the method described by Ryley and Petes in 1970. Hematological studies were carried out using the methods described by Cheesbrough, while biochemical parameters were determined by the method of Reitman and Frankel. Infected mice orally treated with ethanolic extract of A. indica leaves and O. gratissimum as well as the combination produced significant (P<0.05), dose-dependent activity against the parasite throughout the treatment period. Higher reduction was observed at days 4 and 7, and maximum reduction (95.07%) was attained with 24 mg/kg of the combination of each of the extracts on the seventh day. This demonstrates that the combination of O. gratissimum and A. indica had better antimalarial activity than when used individually. The extracts also improved PCV and Hb, in addition to offering a protective effect to the liver. The findings from this work provide justifiable evidence and need to combine plant extracts in malaria treatment in order to improve their efficacy and slow the development of resistance as well.
A Longitudinal Study of the Social Distribution of Mathematics Achievement for a Cohort of Public High School Students.

This paper reports the results of a study of changes in the social distribution of mathematics achievement for a cohort of public high school students. Using hierarchical linear modeling (HLM) the study sought to identify school characteristics which were significantly correlated with changes in achievement differences from grade 9 to grade 11 between: (1) white and black students; (2) students from advantaged and disadvantaged socioeconomic backgrounds (SES); and (3) male and female students. The school characteristics considered included indicators of school/community context, school normative climate ("effective schools" indicators), and school instructional setting. While many of the indicators were found to be related to achievement discrepancies at a given point in time, few yielded significant results for changes in the distribution of achievement. School location (suburban), the stability of the student population, and the percentage of low SES children in the school were significant predictors of change over time. It is suggested that effective-schools indicators which are more focused toward equity issues, and those based on student (rather than teacher) input, may be needed if predictors of change are to be found.

Chromogranin-A Expression as a Novel Biomarker for Early Diagnosis of Colon Cancer Patients

Colon cancer is one of the major causes of cancer death worldwide. The five-year survival rate for the early-stage patients is more than 90%, and only around 10% for the later stages. Moreover, half of the colon cancer patients have been clinically diagnosed at the later stages. It is; therefore, of importance to enhance the ability for the early diagnosis of colon cancer. Taking advantages from our previous studies, there are several potential biomarkers which have been associated with the early diagnosis of the colon cancer. In order to investigate these early diagnostic biomarkers for colon cancer, human chromogranin-A (CHGA) was further analyzed among the most powerful diagnostic biomarkers. In this study, we used a logistic regression-based meta-analysis to clarify associations of CHGA expression with colon cancer diagnosis. Both healthy populations and the normal mucosa from the colon cancer patients were selected as the double normal controls. The results showed decreased expression of CHGA in the early stages of colon cancer as compared to the normal controls. The decline of CHGA expression in the early stages of colon cancer is probably a new diagnostic biomarker for colon cancer diagnosis with high predicting possibility and verification performance. We have also compared the diagnostic powers of CHGA expression with the typical oncogene KRAS, classic tumor suppressor TP53, and well-known cellular proliferation index MKI67, and the CHGA showed stronger ability to predict early diagnosis for colon cancer than these other cancer biomarkers. In the protein–protein interaction (PPI) network, CHGA was revealed to share some common pathways with KRAS and TP53. CHGA might be considered as a novel, promising, and powerful biomarker for early diagnosis of colon cancer.
Transnational Metropolitan Development Strategies and Governance in a Post-Socialist Setting: The Case of Szczecin

Abstract The integration of cities and their regions into transnational networks has become a key municipal strategy, with the creation of a metropolitan governance structure being seen in this context as a fundamental element. The Szczecin Metropolitan Area constitutes an example of meagre results in intercommunal cooperation in post-socialist East-Central Europe. This has its repercussions on the task of creating cross-border metropolitan governance structures including adjacent German counties, a task which, in turn, may help to overcome development barriers. This becomes apparent particularly in the process of defining joint development objectives as well as an image for the cross-border metropolitan region
The coloured Jones function and Alexander polynomial for torus knots

Abstract In [2] it was conjectured that the coloured Jones function of a framed knot K, or equivalently the Jones polynomials of all parallels of K, is sufficient to determine the Alexander polynomial of K. An explicit formula was proposed in terms of the power series expansion , where JK, k(h) is the SU(2)q quantum invariant of K when coloured by the irreducible module of dimension k, and q = eh is the quantum group parameter. In this paper I show that the explicit formula does give the Alexander polynomial when K is any torus knot.
Comparative Study of Strength and Corrosion Resistant Properties of Plain and Blended Cement Concrete Types

The relative performances of mechanical, permeability, and corrosion resistance properties of different concrete types were compared. Concrete types were made from ordinary Portland cement (OPC), Portland pozzolana cement (PPC), and Portland slag cement (PSC). Compressive strength test, effective porosity test, coefficient of water absorption, short-term accelerated impressed voltage test, and rapid chloride permeability test (RCPT) were conducted on M30 and M40 grades of concrete designed with OPC, PPC, and PSC cements for 28- and 90-day cured concrete types. Long-term studies such as microcell and electrochemical evaluation were carried out to understand the corrosion behaviour of rebar embedded in different concrete types. Better corrosion resistant properties were observed for PSC concrete by showing a minimum current flow, lowest free chloride contents, and lesser porosity. Besides, PSC concrete has shown less coefficient of water absorption, chloride diffusion coefficient (CDC), and lower corrosion rate and thereby the time taken for initiation of crack extended.
