Investigation of fatty acid composition of Ammi visnaga seed oil by gas chromatography-mass spectrometry (GC-MS)

The Ammi visnaga seeds oil constituents of methyl ester derivatives of fatty acids were analyzed using gas chromatography coupled with mass spectrometer. The results obtained contain saturated as well as unsaturated fatty acids of A. visnaga seeds oils. A total of 15 different components were identified and quantified. Methyl ester of oleic acid was found in high concentration (13.30%) among the identified analytes of interest. In addition, methyl ester of linoleic acid (11.39%), palmitic acid (7.88%) and stearic acid (1.88%) were found. Concentration of the rest of identified fatty acids analytes were less than 1%. Thus, from the results it is apparent that the therapeutic efficacy of the plant may be due to the presence of high percentage of valuable analytes concentrations detected in the fatty acid of A. visnaga. The reason for the consumption in the pharmaceuticals as well as its wide applications in the prevention of dental carries, for various skin diseases and different infections. Key words: Ammi visnaga, methyl ester, fatty acid, gas chromatography (GC), analyte.
Optimising the smoothness and accuracy of moving average for stock price data

Smoothing time series allows removing noise. Moving averages are used in finance to smooth stock price series and forecast trend direction. We propose optimised custom moving average that is the most suitable for stock time series smoothing. Suitability criteria are defined by smoothness and accuracy. Previous research focused only on one of the two criteria in isolation. We define this as multi-criteria Pareto optimisation problem and compare the proposed method to the five most popular moving average methods on synthetic and real world stock data. The comparison was performed using unseen data. The new method outperforms other methods in 99.5% of cases on synthetic and in 91% on real world data. The method allows better time series smoothing with the same level of accuracy as traditional methods, or better accuracy with the same smoothness. Weights optimised on one stock are very similar to weights optimised for any other stock and can be used interchangeably. Traders can use the new method to detect trends earlier and increase the profitability of their strategies. The concept is also applicable to sensors, weather forecasting, and traffic prediction where both the smoothness and accuracy of the filtered signal are important.
Acoustic properties of macrophytes: Comparison of single-beam and multibeam imaging with modeling results

Macrophytes are an important part of marine habitats, as primary producers and shelter for marine life. Some species, like Laminaria digitata, have acoustic properties very close to water, in terms of density and impedance, but their imaging is possible using high frequencies. This paper focuses on the comparison of multibeam and single-beam measurements of macrophytobenthos in Arctic, using Biosonics DTX (420-kHz frequency) single-beam and Imagenex Delta-T 837 imager (260-kHz frequency). This comparison investigates the role of angular response for bottoms covered by macroalgae, supplementing these field results with measurements of macrophytes suspended in the Arctic water column (i.e. without bottom influence). Detailed measurements of the morphology of dominant, Arctic seaweed species were taken to specify their acoustic properties. Data about mean leaf size, body density and undulations or roughness of macroalgae thallus surface were collected for Laminaria digitata and Saccharina latissima. It helps to estimate how much of the acoustic energy is reflected, absorbed and scattered by the seaweed layer and how much bottom substrata influence this process.
Recent Volatility in Stock Markets in India and Foreign Institutional Investors

After the first few phases of polling of the general election in India, there was a sudden and sharp increase in stock market volatility in this country. Apparently, the prospect of a non-BJP government in the center made the big players in the stock market nervous about the continuation of the ongoing reform measures in India. Largely owing to selling pressures from foreign institutional investors (FIIs), the Bombay Stock Exchange Sensitivity Index (Sensex) declined from about the 5,900 on 22 nd April to around 4,500 on May 18 th . On 17 th May, it registered a record 800 point decline, which is the steepest fall in the 130-year-old history of the stock exchange, before recovering to close 564 points lower. To calm these investors, senior Congress leaders had to issue statements reaffirming their faith in the market oriented ‘reform’ measures. Even though the verdict of the general election was seen as a mandate against the neo-liberal economic policies pursued by the outgoing government, the upheavals of the stock markets managed to influence the new government’s policies even before the new ministry was formed. The apparent ease in which the stock market and institutional investors managed to influence policymaking created a debate in India. In the financial media there was a view that the decline of the Sensex happened because major ‘market’ players was wary about the political stability of the new regime and they did not approve of the policy statements made by some of the leaders of the United Progressive Alliance. These investors showed their disapproval and lack of confidence in the new government by withdrawing from the market. However, many analysts suspected that it was an attempt by financial rentiers, particularly foreign institutional investors, to overrule the anti-reform verdict delivered in the election and nudge policy makers towards adopting neo-liberal policies which essentially suit these investors. Given this controversy, this paper aims to take a detailed look at the stock market and the behavior of different investor groups, especially the FIIs, in India for the period March 2004 to June 2004. The objective of the paper is also to investigate how the withdrawal of foreign portfolio capital in the post election phase has affected the price and equity holding pattern of different Sensex companies. This will help us understand the dynamics of the stock market crash in the post election period. This paper is organized in the following manner. Section 2 looks at the movement of the Sensex and measures its volatility in the recent months, section 3 investigates the pattern of foreign portfolio investment and its influence on the Sensex, section
Long-distance migration: evolution and determinants

Long distance migration has evolved in many organisms moving through different media and using various modes of locomotion and transport. Migration continues to evolve or become suppressed as shown by ongoing dynamic and rapid changes of migration patterns. This great evolutionary flexibility may seem surprising for such a complex attribute as migration. Even if migration in most cases has evolved basically as a strategy to maximise fitness in a seasonal environment, its occurrence and extent depend on a multitude of factors. We give a brief overview of different factors (e.g. physical, geographical, historical, ecological) likely to facilitate and/or constrain the evolution of long distance migration and discuss how they are likely to affect migration. The basic driving forces for migration are ecological and biogeographic factors like seasonality, spatiotemporal distributions of resources, habitats, predation and competition. The benefit of increased resource availability will be balanced by costs associated with the migratory process in terms of time (incl. losses of prior occupancy advantages), energy and mortality (incl. increased exposure to parasites). Furthermore, migration requires genetic instructions (allowing substantial room for learning in some of the traits) about timing, duration and distance of migration as well as about behavioural and physiological adaptations (fuelling, organ flexibility, locomotion, use of environmental transport etc) and control of orientation and navigation. To what degree these costs and requirements put constraints on migration often depends on body size according to different scaling relationships. From this expos it is clear that research on migration warrants a multitude of techniques and approaches for a complete as possible understanding of a very complex evolutionary syndrome. In addition, we also present examples of migratory distances in a variety of taxons. In recent years new techniques, especially satellite radio telemetry, provide new information of unprecedented accuracy about journeys of individual animals, allowing re-evaluation of migration, locomotion and navigation theories.

Contribution of microbial associations to the cadmium uptake by peppermint (Mentha piperita)

Due to the high cost of conventional clean-up technologies, there is a growing interest in the use of phytoremediation i.e. the use of plants to remove, degrade or immobilize contaminants. However phytoremediation is somewhat limited by the possibility of consumption by plants from occurrence of biomagnification. Cultivation of aromatic plants is therefore recommended, as essential oil is not prone to heavy metals contamination. There is also a recent surge in research focusing on the use of plant–microbial associations to increase or decrease metal accumulation by plants. The experiment was conducted in a CRD factorial design. The factors comprised of sulfur (0, 0.5 and 1gS/kg soil), thiobacilli (Sulfur Oxidizing Bacteria, SOB) and mycorrhizal inoculation (MI). Plastic pots were treated with 50 mg/kg of cadmium using cadmium nitrate (Cd (NO3) 2.4H2O. Applications of sulfur and/or SOB in combination with MI resulted in a significant additive effect on a root’s Cd uptake and root bio concentration factor. Low Teranslocation Factor showed that less Cd from the peppermint root was translocated to the shoot. Approximately all Cd remained in the residues after distillation and essential oil was free from Cd in all treatments.
Spatial patterns of light gaps in mesic grasslands

Abstract The spatial pattern of light gaps in mesic grasslands in central Texas with contrasting disturbance histories was assessed using patch-based landscape metrics determined from a threshold level (25% of full sunlight), as light intensities below this threshold substantially decrease survival of honey mesquite (Prosopis glandulosa var. glandulosa Torr.) seedlings. The spatial pattern of light gaps, with the exception of edge density, were significantly different between annually-disturbed and non-disturbed grasslands on all sample dates (2 April, 30 April, 29 May, and 26 June 1998). Differences in patch metrics did not occur between non-disturbed grasslands despite contrasting vegetation composition [perennial forbs and perennial bunch (tussock) grasses]. Patch-based landscape metrics of light gaps did vary temporally in both annually-disturbed and non-disturbed grasslands. The structure and spatial configuration of light gaps were distinctly different between annually-disturbed and non-disturbed grasslands: a low density of large patches characterized light gaps in annually-disturbed grassland, whereas non-disturbed grasslands had a high density of small patches. Our findings demonstrate that the current disturbance regime is the principal environmental driver influencing species dominance and composition, and indirectly vegetation structure, which collectively contribute to the observed dynamics of light gap patches in these mesic grasslands. Incorporating spatially explicit consideration of light gap structure and dynamics into experimental studies addressing invasion of weedy plant species such as honey mesquite may be an effective approach to address mechanisms and the ecological significance of disturbance operating as a driver facilitating woody plant invasions in mesic grasslands.
Effect of supplemental nitrogen from urea on digestibility, rumen fermentation pattern, microbial populations and nitrogen balance in growing goats

For this study, four Thai Native (TN) x Anglo Nubian (AN) crossbred growing goats with an average liveweight of 19.0+1 kg were randomly used in a 4x4 Latin square design to determine the effect of supplemental nitrogen from urea on digestibility, rumen fermentation pattern, microbial populations and nitrogen balance in growing goats. Fresh elephant grass (FEG) was offered ad libitum as the roughage. Four dietary treatments with supplemental nitrogen from urea were T 1 = urea at 0% cassava chip, (CC = 30%), T 2 = urea at 1% (CC = 40%), T 3 = urea at 2% (CC = 50%) and T 4 = urea at 3% (CC = 60%), respectively. Based on this experiment, it was found that there was no significant difference (p>0.05) among treatment groups regarding nutrient intake (OMI, CPI, NDFI and ADFI) and digestion coefficients of nutrients (DM, OM, CP, NDF and ADF), while digestible nutrient intake of CP (g/d) was affected by increasing urea levels. Ruminal volatile fatty acid profiles were similar among treatments. Moreover, rumen microorganism populations were not affected (p>0.05) by increasing urea levels. The amount of N absorption and retention were similar among treatments, except for T 4 which tended to be slightly lower in N absorption as compared to control diet, but higher N output retained (% of N intake) than the control-fed goats. From the overall results, it can be concluded that a higher level of urea (3%) could be used with a high level of CC (60%) in concentrate when fed with FEG and it was found to be a good approach to exploiting the use of local feed resources for goat production.
STAR: Improved Algorithm based on Sliding Window for Trust-Aware Routing in WSNs

This research with attention to the establishment of trust in WSNs and with the goal of increment in energy supply and growth in malicious node detection accuracy by using of improved sliding window, is saving energy by using computation of the previous periods. Also, this research calculates the trust in aspect of transferring information, based on subjective logic model and incremented the detection rate of malicious node by proposing two algorithms for identifying these nodes. Then, this method increases the speed of routing. The results of simulation of STAR compared to EDTM (Jiang, et al., 2015) shows 11.99% increment in the residual energy of network and growth of 1.52% in detecting the accuracy of malicious nodes.
Challenges of Strategy Implementation on Performance of Constituency Development Fund Projects in Kenya: A Case of Marakwet West Constituency

Constituency development fund was adopted by the government of Kenya in 2003 as a people centered approach to development. The study examined the challenges in strategy implementation on performance of Constituency Development fund Projects and established measures. The research questions were: to what extent did leadership, cultural receptivity, structural facilitation and communication posed a challenge to the performance of Constituency Development Fund projects? And what measures should be taken? It adopted descriptive research design. Targeted 263 Management Committees. Stratified random sampling was used to select 79 respondents. Questionnaire and Interview Guide were used to collect data. Descriptive statistics was used for data analysis. The findings were leadership, cultural receptivity; structural factors and communication were identified to be challenges to performance of projects. Measures established included training of various committees through workshops, incorporating well educated people in various committees, involving all stakeholders in the implementation processes and adopting effective and efficient methods of transferring information. The study recommended the need for management to develop an organizational culture that allows successful implementation of Constituency Development Fund projects.
Does Non-farm Income Improve or Worsen Income Inequality? Evidence from Rural Ghana

This paper uses nationally representative household survey data of 2006 to examine the effect of non-farm income on income inequality in rural Ghana. Employing the Gini-decomposition technique, results indicate that aggregate non-farm income increased income inequality among rural households in Ghana. In terms of its components, while non-farm self-employment income reduced income inequality, non-farm wage income increased income inequality. A factor-decomposition of inequality revealed that education is the single most important variable contributing to the inequality-increasing nature of non-farm income. The effect of education on inequality is more pronounced for non-farm wage income. The policy implication is for a narrowing of education inequality among rural households in Ghana to create greater access to non-farm employment to reduce rural income inequality and poverty.
Mesures de corrélations dans un gaz de bosons unidimensionnel sur puce

Nous presentons dans ce manuscrit des mesures de correlations spatiales a un et deux corps effectuees sur un gaz de bosons unidimensionnel et ultra-froid piege a la surface d'une microstructure. Les correlations a deux corps sont mises en evidence par des mesures de fluctuations de densite in situ ; les correlations a un corps sont sondees grâce a des mesures de distributions en impulsion. Nous avons observe des fluctuations de densite sub-poissoniennes dans le regime d'interactions faibles, mettant ainsi en evidence pour la premiere fois le sous-regime du regime de quasi-condensat dans lequel la fonction de correlation a deux corps est dominee par les fluctuations quantiques. Nous avons egalement observe des fluctuations sub-poissoniennes quelle que soit la densite dans le regime d'interactions fortes ; notre mesure constitue la premiere observation d'un unique gaz de bosons unidimensionnel dans ce regime. Le piege magnetique que nous avons utilise est un piege module qui possede la propriete remarquable de decouplage entre confinements transverse et longitudinal. Cette specificite nous a permis de faconner a volonte la forme du confinement longitudinal. En particulier, nous avons pu obtenir des pieges harmoniques et quartiques. Nous avons egalement utilise les proprietes de ce piege module afin de realiser une lentille magnetique longitudinale. Cette technique nous a permis de mesurer la distribution en impulsion du gaz, dans le regime d'interactions faibles. Nous presentons deux resultats, obtenus de part et d'autre de la transition molle entre les regimes de gaz de Bose ideal et de quasi-condensat. Sur le plan theorique, nous montrons qu'une theorie de champ classique ne suffit pas a decrire quantitativement cette transition molle pour les parametres typiques de l'experience. Nous avons donc recours a des calculs Monte-Carlo quantiques. La temperature extraite de l'ajustement de nos donnee par ces calculs est en bon accord avec celle obtenue en ajustant les fluctuations de densite in situ avec la thermodynamique de C. N. Yang et C. P. Yang. Enfin, nous demontrons une methode de compensation de la gravite (piegeage harmonique residuel) lors de la phase de lentille magnetique, qui nous permet d'ameliorer considerablement la resolution en impulsion de cette technique.
Lipid profile and protective effects of aqueous extracts of some leguminous plant sprouts against doxorubicin-induced organs impairment in female wistar rats

Doxorubicin is one of the anthracycline drugs used in the treatment of cancer but with an attendant cardiotoxicity. Hence, this study aims to investigate the lipid profile and the protective effects of aqueous extract of seedlings of three leguminous plants: honey beans, big white beans (Vigna unguiculata) and African yam beans (Spenostylis stenocarpa) on doxorubicin induced organs damage in female Wistar albino rats. The sprouts of the three beans were obtained after 4 weeks of planting and the respective aqueous extracts were obtained and used to treat female rats that were induced with different concentrations of doxorubicin per unit body weight. The animals were sacrificed under chloroform anesthesia after induction and treatment for 28 days. The total cholesterol, HDL-cholesterol, LDL-Cholesterol, triglycerides and lipid peroxidation were determined from plasma, liver, heart and kidney using standard methods. The results showed that doxorubicin significantly and progressively lowered the cardiac tissues triglycerides, high density lipoprotein-cholesterol (HDL-cholesterol) and total cholesterol, while significantly causing elevation in low density lipoprotein-cholesterol (LDL-Cholesterol) and malondialdehyde (MDA) concentrations when compared to the control group, while 10% aqueous extract of the various sprouts produced significantly, the reversal to the control level in concentration dependent manners. These results however showed that doxorubicin is a potential organ impaired drug, while the aqueous sprouts extracts produce protective effects on the organs which support the folkloric use of aqueous extract of the plant in the management of suspected patients with organs impairment.

Primary Nb-Ta minerals in the Szklary pegmatite, Poland: New insights into controls of crystal chemistry and crystallization sequences

Abstract An assemblage of primary, extremely As- and Sb-rich, Nb-Ta minerals from the Szklary pegmatite includes columbite-(Fe), columbite-(Mn), tantalite-(Mn), stibiocolumbite, stibiotantalite, an as yet unnamed (As,Sb,U)-rich (Ta,Ti)-oxide, Mn3UAs2Sb2Ta2Ti2O20, and holtite. Anomalous trends of Mn-Fe and Ta-Nb fractionation in the columbite group and crystallization sequences in the primary assemblage can be explained by the contamination of the pegmatite-forming melt by ultramafic and mafic wall-rocks, the competition among these minerals for Ta and Sb and with biotite and tourmaline for Mg, Fe, and Ti, and local variations in melt composition. A hot magmatic fluid, exsolved from the parental melt, reacted with the primary Nb-Ta oxides, inducing two different patterns of alteration. The columbite-group minerals were altered to fersmite, pyrochlore, and bismutopyrochlore locally grading to plumbopyrochlore, whereas stibiocolumbite, stibiotantalite, and the (As,Sb,U)-rich (Ta,Ti)-oxide altered to stibiomicrolite, uranmicrolite grading to betafite, and then to bismutomicrolite or Bi-dominant betafite. In all of the secondary pyrochlore-group minerals, Ta-Nb fractionation is comparable to, or only slightly greater, than that in the primary Nb-Ta oxides, indicating a modest differentiation of the residual melt coexisting with the fluid.
