Time-Kill Assay of 4-Hydroxypanduratin A Isolated from Kaempferia Pandurata Against Foodborne Pathogens

Time–kill assay was performed for 4-hydroxypanduratin A that was isolated from Kaempferia pandurata rizhome against four important foodborne pathogens, namely Bacillus cereus ATCC 21772, Bacillu subtilis ATCC 6633, Staphylococcus aureus ATCC 29737, and Proteus mirabilis ATCC 21100. The methods have been investigated in term of Minimum Inhibitory Concentration (MIC) and killing time curve using methods of Clinical and Laboratory Standards Institute (CLSI) guidelines. The results showed that 4-hydroxypanduratin A rapid acting in killing bacteria as follow: B. cereus : 1×MIC for 4 h, P. mirabilis : 4×MIC for 0.5 h, meanwhile B. subtilis and S. aureus were 1×MIC for 2 h. In conclusion, 4-hydroxypanduratin A showed strong antimicrobial activity against four important foodborne pathogens.
THEORETICAL OBSERVATION ON THE EXPERIMENTAL DATA OF Ge-Se-Tl SYSTEM

Understanding of the effect of addition Tl on glassy Ge-Se have been experimentally and theoretically investigated. The correlation between the optical gap opt g E , the activation energy σ E ∆ , the pre-exponential factor o σ and theoretical calculations has greatly improved with the advent of several structural and chemical models which predict the influence of such an addition, in terms of the average number of constrains con N , the effective average coordination number , the average heat of atomization s H , the glass forming ability and the number of Lone-pair (LP) electrons. The decrease in σ E ∆ and o σ with increasing Tl content has been discussed on the basis of structural changes in Ge-Se which leads to a readjustment in the local enviroment. Thallium is supposed to form states different from the valence states of elements interacting with Ge-Se according to the octet rule (8-N). A correlation has been found between the Ge-Se-Tl glassy system and the number of LP electrons. The stable vitreous state can be obtained only if enough lone-pair electrons exist in the structure of the glassy system. A simple criterion for computing the ability of a semiconductor system to retain its vitreous state is proposed. Investigation of the experimental data of the Ge-Se-Tl glassy system revealed that con N and has a

Staphylococcus epidermidis is a common commensal coloniser of the human skin and is currently the most frequent cause of biomaterial associated infections. Several studies have attempted to identify the determinants that distinguish invasive from commensals S. epidermidis strains. Its pathogenesis is directly related to its ability to establish multi-layered and highly structured biofilms, resistant to antimicrobial agents. This bacteria expresses several protein factors that are responsible for the development of the biofilm, including the contribution of specific factors (icaA, aap and bhp genes) in the accumulation phase. In the last years, several research groups have been trying to understand the contribution of biofilm-associated genes involved in biofilm formation. Therefore, the aim of this thesis was to analyse the gene expression of icaA, aap and bhp and compare with the formation of the biofilm structure. Two S. epidermidis strains, one isolated from a hospital environment and another from the skin of a healthy person were characterized at the level of biofilm formation, at different times of incubation. According to our results, both strains demonstrated an increase of biomass production over time, revealing the importance to use screening assays with more than 24 h of incubation. A biofilm structure analysis was also performed to detect the presence of poly-N-acetylglucosamine (PNAG), the major component of S. epidermidis biofilm matrix. The results demonstrated a higher production of PNAG only after 48 h for SECOMO034.A1. Due to the low sensitivity of the method or low quantity of proteins produced, it was not possible to determine the concentration of proteins in the biofilm matrix. Finally, the gene expression at two different biofilm formation times were determined, confirming the importance of the icaA gene in the accumulation stage, explaining the high production of biomass and PNAG. On the other hand, the aap and bhp expression levels raised some questions about their role in the biofilm process.
THESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Thermal and Photon Stimulated Reactions on Metal Particles

The interaction between molecules and solid surfaces influence our daily lives in many ways. One important example is heterogeneous catalysis where surface reactions, for example, are used for production of chemicals and exhaust after-treatment. As surface reactions are complex, various different approaches are needed to explore the fundamental processes. One route is to study reactions at well-defined single crystal surfaces under ultra-high vacuum (UHV) conditions. However, as the reaction pathways may depend on pressure, ideally we would like to track how and if the interactions change with pressure. Furthermore, technical catalysts generally consist of nanometre-sized particles supported by an oxide material. This introduces the complexity of particle size-dependence, as well as effects arising from interactions between the reactants and the support material. The studies in this thesis range from fundamental studies in UHV to experiments under ambient conditions. Structure-wise, the studies encompass single crystal substrates and model catalysts. Furthermore, surface processes are stimulated by both thermal and photon energy. The fundamental aspects of thermally driven interactions of NO and water with sodium supported on a single crystal C(0001) surface were studied in UHV. Moreover, the influence of silver particle size (and to some extent shape) on the efficiency of photon driven desorption of NO from the Ag/C(0001) system was explored. Model catalysts were studied under ambient conditions by use of indirect nanoplasmonic sensing (INPS). In particular, INPS was used to determine the apparent activation energy for hydrogen oxidation as a function of platinum nanoparticle size, and to track the sintering of platinum clusters.
Permafrost evolution under the influence of long-term climate fluctuations and glacio-eustatic sea-level variation: region of Laptev and East Siberian Seas, Russia

Results of a five-year investigation of permafrost and gas-hydrate stability zone evolution on the Laptev and East Siberia Seas shelf are presented. For investigation of permafrost and gas hydrate stability zone (GHSZ) evolution during the Middle Pleistocene– Holocene (last 400 ka), a palaeo-geographic scenario and numerical model were developed. The model takes into consideration the duration of permafrost agradation and degradation, existence of permafrost temperature zonality, different geological composition and geothermal heat flux in different geological structures etc. Based on the modelling the following conclusions can be made. Both offshore permafrost and GHSZ recently exist from the shoreline till to the upper part of continental slope. Delay of the maximal permafrost thickness relative to the climatic extremes and different evolution of offshore permafrost thickness and GHSZ at different seawater depths is shown.
Structure and quantitative structure-activity relationship (QSAR) for (Â±) 3, 5-diphenyl-2-thioxoimidazolidin-4-ones as prominent cyclooxygenase-2 inhibitors

Cyclooxygenase (COX), a key enzyme playing crucial role in prostaglandin biosynthesis in Rheumatoid arthritis (RA) inflammation. For targeting COX-2 isoform, it is therefore interesting to design new molecule scaffolds with reduced side effects at gastric and renal levels. QSAR can modify the molecular structures for achieving the desired molecule with the proposed property, without experimental measurement. In the current study, we extend a published work that had been investiged the of 3, 5-diphenyl-2thioxo imidazolidin-4-ones derivatives as cyclooxygenase inhibitors. In this report, QSAR and regression analysis were used to predicate the cyclooxygenase inhibition activity of these derivatives. Moreover the cyclooxygenase inhibition activity for these molecules that was obtained experimentally is compared with the calculated ones. The cyclooxygenase inhibition activity of some of newly postulated 3, 5-diphenyl-2thioxo imidazolidin-4-ones derivatives showed a pronounced cyclooxygenase inhibition activity. QSAR and regression equations were useful in predicating the biologic activity of the old and postulated molecules with good validity.
Effect of Color-coding on Locus of Control.

This study examined the effects of color on information processing strategies of internal and external locus of control learners. Specific objectives were to: (1) examine the instructional effectiveness of two types of visualized instruction in facilitating achievement for students with different learning styles; (2) determine whether an interaction exists between types of learning style and instructional treatment; and (3) determine whether specific instructional treatments were equally effective in facilitating achievement for students with different learning styles. Participants were 107 college students who were classified as external, neutral, or internal locus of control based on their scores on the Rotter Internal-External Locus of Control Scale. Students in the first treatment received an instructional booklet containing directions, prose, and visuals in black and white; students in the second treatment received identical prose instructions and visuals, but their visuals were color-coded. The instructional content related to the anatomy and functions of the human heart. Students were administered drawing, identification, terminology, and comprehension tests. Results indicated that students who received the color-coded treatment scored significantly higher on the identification, drawing, and overall assessments. An outline of the color coding scheme and a table of means and standard deviations for all comparisons are included.

Environmental Conditions and Vegetation Recovery at Abandoned Drilling Mud Sumps in the Mackenzie Delta Region, Northwest Territories, Canada

Historical data from oil and gas exploration in the delta of the Mackenzie River, Northwest Territories, in the 1970s provided an opportunity to estimate decadal-scale impacts of exploratory oil and gas drilling on native plant communities in low Arctic tundra. We assessed changes in vegetation composition and associated environmental gradients across seven drilling mud sumps in the Kendall Island Bird Sanctuary, Mackenzie Delta. Three decades after disturbance, drilling sumps had developed vegetation coverage equivalent to that in undisturbed areas, although bare soil persisted in ponded areas and where a salt crust was present. Vegetation on sumps was composed of communities dominated by forbs, grasses, and tall shrubs that were distinct from adjacent, undisturbed sedge and low shrub communities. The area of altered vegetation around a sump was generally larger in upland or saline environments than in lowland areas. Pooled water observed around many sumps was likely associated with thaw subsidence that occurred following construction, which was subsequently compounded by snow drifting and increased soil temperatures along the margins of the sump mound. Changes in drainage, active-layer depth, and surface salt concentrations appear to be key environmental factors that have helped shape plant communities established on drilling sumps in the three decades after disturbance.
Detection of transgenic maize Cry1Ab protein subjected to ruminal digestion

This research determined the extent of ruminal degradation of a transgenic protein (Cry1Ab) expressed in kernels of maize (Zea mays) cultivar DKC53-32. Cracked kernels of transgenic maize (Bt+) were subjected to rumen digestion using in situ experiments with two ruminally cannulated Holstein cows. A non-transgenic maize cultivar (Bt-) was used as a control for crude protein (CP) degradation. CP and Cry1A concentrations from dacron polyester bags inserted in the rumen were determined for 48 h. The Btcultivar had greater CP content (P<0.05) than the Bt+ maize, but no difference (P>0.05) was found in ruminal degradable protein and the CP rate of degradation. The Cry1Ab protein was detected throughout ruminal digestion. The amount of Cry1Ab protein remaining after 16 and 24 h of ruminal degradation was 85 and 60%, respectively. These results indicated that a significant fraction of Cry1Ab protein was not digested in the rumen. This is the first report of the rumen degradation rate of a transgenic protein.
AFLP Variation in Agamospermous and Dioecious Bluegrasses of Western North America

Native perennial bluegrasses are common and persistent in the understory steppe vegetation of western North America. The agamospermous Poa secunda Presl. complex circumscribes a number of commonly recognized forms including big bluegrass (P. ampla Merr.), canby bluegrass (P. canbyi Scribn.), and sandberg bluegrass (P. sandbergii Vasey). Poa fendleriana (Steudel) Vasey is a dioecious, morphologically distinct bluegrass species that is also native to western North America. The amplified fragment length polymorphism (AFLP) method was used to analyze genetic variation within and among cv. Canbar canby bluegrass, cv. Sherman big bluegrass, two allopatric natural populations of sandberg bluegrass, and one natural germplasm source of P. fendleriana. Results indicate that Sherman and Canbar are comprised of one or several fixed genotypes, respectively, that are related to sandberg bluegrass. Although several fixed genotypes were also detected within the two natural sandberg bluegrass populations, high levels of genetic diversity were present in the agamospermous sandberg populations and dioecious P. fendleriana population. Patterns of AFLP variation in P. secunda are consistent with facultative apomixis and outcrossing mode of reproduction. Moreover, population differentiation between the two highly diverse natural sandberg bluegrass populations, collected from sites nearly 600 km apart, is very low (G s = 0.14) and reflect a high degree of gene flow. However, the AFLP profiles of Canbar canby bluegrass and Sherman big bluegrass were distinct from sandberg bluegrass. The P. secunda complex, as a group, was clearly distinguishable from P. fendleriana. Thus, DNA fingerprinting was used to characterize naturally diverse bluegrass germplasm sources that may he used for large-scale revegetation efforts across the western USA.
Robust sensor coverage in a two-dimensional area

This master thesis is about robust sensor coverage in a two-dimensional space where sensors may fail. In this research we tried to find the optimal deployment with the shortest distance from any point in the considered area to the closest sensor, which is called the cost of a sensor deployment. To compare the quality of the sensor deployments, a random uniform deployment and a grid deployment are used. The quality of the sensor deployments is analyzed and a lower bound for the cost is created. Furthermore, algorithms are defined to minimize the cost and the convergence properties of these algorithms are examined.
Firm Size and the Intensive Margin of Import Demand

We use French microdata to test an ubiquitous property of firm-based models of importing. When firm efficiency is factor neutral and input prices and qualities are common across firms, firm size should have no effect on expenditure shares on the different products and varieties sourced, holding the extensive margin constant. We show that this property is not supported by the data. Holding the sourcing strategy fixed, we find that larger firms (i) have lower import shares, (ii) concentrate their import spending on their top varieties and (iii) pay higher prices for their imported inputs. Our findings imply that input trade, through the intensive margin, is less beneficial for larger firms. Our results are consistent with a complementarity between firm productivity and input quality.
New Urbanism and the City Planning (Implications of the Application of the New Urbanism Principles on the Land Uses in Al-Karkh in Baghdad City)

Over the past 60 years, towns and cities were under a great transformation. The city has become less defined through its physical boundaries with a development 0f suburban area with a huge number 0f separate houses. The City is the essence 0f our civilization and it provides a frame for social life. Gardens, streets planner, and yard brings people together well and gives them a chance 0f social encounters, which have economic also. Friendly and beautiful cities can bring life insurance to people in urban areas. The ”New Urbanism” is the most influential planning movements since the late twentieth century. The planning ideas and successful projects 0f new urbanism lead us to better living conditions. Under the influence 0f globalization, the urban construction 0f cities inevitably influenced by the impact 0f new ideas and at the same time, during the process 0f construction emerged some urban problems. Activities in the city need a particular place or space that can be done by the coordinate 0f that space. The place or the land is the most important factor in shaping the physical environment and the context 0f urban activities. It has always been regarded as a base for urban construction by planners. Planning 0f land use ”as the core 0f urban planning” plays an important role in the spatial and temporal organization 0f cities. The study 0f new urbanism principles in land use planning in urban areas is based on its benefits on planning at all levels 0f the study 0f human communities 0f mass and streets in the regions and cities. Over the past decades, the city 0f Baghdad has grown rapidly in a random and uncontrolled way and a kind 0f unsustainable urbanization has taken place.

Production of Citric Acid from Corncobs with Its Biological Evaluation

Corncobs could serve as a substrate for citric acid production using solid state fermentation technique. The culture optimization concerning substrate concentration, culture duration, pH, temperature and substrate hydrolysis was carried out for maximum productivity of citric acid. Under the optimized conditions, 48.4 g of citric acid was produced from 1 kg dry corncobs. Biological evaluation was carried out for citric acid such as melanin synthesis inhibitory, anti-allergy, anti-bacterial, and hyaluronic acid production activities. The results showed that citric acid has potent melanin inhibitory activity, good inhibition for β-hexosaminidase release and potent stimulatory effect for the production of hyaluronic acid. These activities (melanin synthesis inhibitory, anti-allergy and hyaluronic acid productive activities) of citric acid have been reported for the first time.
Screening of 15 Chickpea Germplasm Accessions for Resistance to Ascochyta rabiei in North West of Algeria

Ascochyta blight is an economically important disease of chickpea caused by the fungus Ascochyta rabiei. The fungus shows considerable variation for pathogenicity in nature. Fifteen chickpea germplasm accessions provided by ICARDA (Aleppo, Syria), their origin from different countries (Table 1), were screened for resistance to Ascochyta blight disease caused by Ascochyta rabiei, by artificially inoculating the germplasm under glasshouse at temperature ranged from 20±2°C and humidity was maintained above 80% by sprinkling fresh water. Highly significant effect (P<0.01) was observed on chickpea germplasm reaction to three pathotypes of Ascochyta rabiei (Mos02 'pathotype III: highly aggressive', At02 'pathotype II: moderate aggressive' and Sba02 'pathotype I: least aggressive'). We found 5 chickpea germplasm exhibited highly resistant response (ILC72, ILC182, ILC187, ILC200 and ILC202), 2 are susceptible (ILC1929 and Flip1025) and other 8 chickpea germplasm (ILC484, ILC2506, ILC3856, ILC4421, ILC5902, ILC5921, ILC6043 and ILC6090), displayed tolerant reaction.
On the electronic properties of some metals using density-functional theory

The use of density functional theory as a viable tool for investigating the electronic structure of both periodic and disordered system at ground state has been emphasized. In this study, we employ local density approximation and plane wave formalism via Quantum ESPRESSO, the selected metals was observed to exhibit degenerate but overlap bands except Copper and Silver whose inner d state function transits its broader s state. The study shows the efficacy of density functional theory as a promising tool for explaining electronic properties of metal.
The Effects of Perceived Attractiveness on Expected Opening Gambit Style

Opening gambits, informally known as pick-up lines, are brief verbal transmissions generally used to initiate a conversation with a potential mate. One potential factor that could play a role in the effectiveness of an opening gambit is the physical appearance of the contributor. A person’s physical appearance can be influential on other’s opinions and judgments, often leading into stereotyped expectations. The present study addressed the possibility that opening gambit expectations, from the perspective of the recipient, would be impacted by the approaching individuals’ physical appearance, specifically their facial attractiveness. Results indicated that participants expected attractive individuals to use direct opening gambits (M = 10.84, SD = 3.33) more often than less attractive individuals (M = 5.87, SD = 2.87), F(1,114) = 72.97, p < . 001, ηp = . 39. Less attractive individuals were expected to more often use innocuous (Less attractive: M = 11.75, SD = 4.55; Attractive: M = 9.64, SD = 2.01), F(1,114) = 8.91, p = . 003, ηp = . 07, or flippant opening gambits (Less attractive: M = 7.28, SD = 4.35; Attractive: M = 4.62, SD = 2.25), F(1,114) = 13.01, p < . 001, ηp = . 10. The results also showed interactions between the expected opening gambits usage, the attractiveness of the stimulus, and the target gender stimulus. This study illustrates the impact that perceptions of facial attractiveness have on expectations regarding the initiation of social interactions and potential romantic relationships.
