Background: Objective Structured Clinical Assessment (OSCA) is effectively known to ascess students’ clinical skills, but it often increase. One of treatment to reduce anxiety is progressive relaxation. Objective: To evaluate the effectiveness of progressive relaxation to reduce nursing student anxiety before doing the OSCA. Method : the study is a pre experimental research. Using pretest and posttest one group design. Population study was fifth semester of nursing students when doing OSCA test at surgical state count 107 persons. The sample was 30 respondents. From an accidental sampling. This research usen STAI (State-Triat Anxiety Inventory) questioner to score the level of anxiety and progressive relaxation. Data analysis used wilcoxon test and mann whitney test. Results: pre test of experiment group, there were 20% respondents with medium anxiety, 20% with high anxiety. Post test, 66,7 % experiment group with medium anxiety and 33,3% respondents with high anxiety. Result of wilcoxon test, with p – value = 0,005, and Mann Whitney with p-value = 0,04. Conclusion : there was an influence progressive relaxation to anxiety of nursing student before do the OSCA. Suggestion : Students can use progressive relaxation techniques as one technique in reducing anxiety levels.Limitations of the Study: Implementation of progressive relaxation is given only one therapy, so the anxiety score still tends to be high. OSCA examination with kloter system makes the researcher get less than 30 student respondents. Keyword: OSCE, OSCA, Nursing, Anxiety Levels, progressive relaxation, STAI.
Upwelling of Atlantic Water along the Canadian Beaufort Sea Continental Slope: Favorable Atmospheric Conditions and Seasonal and Interannual Variations

AbstractThe role of wind forcing on the vertical displacement of the −1°C isotherm and 33.8 isohaline depths was examined based on snapshots of historical (1950–2013) temperature and salinity profiles along the Mackenzie continental slope (Beaufort Sea). It is found that upwelling is correlated with along-slope northeast (T59°) winds during both ice-free and ice-covered conditions, although the wind impact is more efficient during the ice-free season. One of the most important factors responsible for vertical displacements of isopycnals is sustained wind forcing that can last for several weeks and even longer. It accounts for 14%–55% of total variance in isotherm/isohaline depths, although these numbers might be underestimated. The upwelling and downwelling events are discussed in the context of the interplay between two regional centers of action—the Beaufort high and Aleutian low—that control the wind pattern over the southern Beaufort Sea. The probability of upwelling-favorable wind occurrence is close.
Endoplasmic Reticulum Protein TXNDC5 Interacts with PRDX6 and HSPA9 to Regulate Glutathione Metabolism and Lipid Peroxidation in the Hepatic AML12 Cell Line

Non-alcoholic fatty liver disease or steatosis is an accumulation of fat in the liver. Increased amounts of non-esterified fatty acids, calcium deficiency, or insulin resistance may disturb endoplasmic reticulum (ER) homeostasis, which leads to the abnormal accumulation of misfolded proteins, activating the unfolded protein response. The ER is the primary location site for chaperones like thioredoxin domain-containing 5 (TXNDC5). Glutathione participates in cellular oxidative stress, and its interaction with TXNDC5 in the ER may decrease the disulfide bonds of this protein. In addition, glutathione is utilized by glutathione peroxidases to inactivate oxidized lipids. To characterize proteins interacting with TXNDC5, immunoprecipitation and liquid chromatography–mass spectrometry were used. Lipid peroxidation, reduced glutathione, inducible phospholipase A2 (iPLA2) and hepatic transcriptome were assessed in the AML12 and TXNDC5-deficient AML12 cell lines. The results showed that HSPA9 and PRDX6 interact with TXNDC5 in AML12 cells. In addition, TXNDC5 deficiency reduced the protein levels of PRDX6 and HSPA9 in AML12. Moreover, lipid peroxidation, glutathione and iPLA2 activities were significantly decreased in TXNDC5-deficient cells, and to find the cause of the PRDX6 protein reduction, proteasome suppression revealed no considerable effect on it. Finally, hepatic transcripts connected to PRDX6 and HSPA9 indicated an increase in the Dnaja3, Mfn2 and Prdx5 and a decrease in Npm1, Oplah, Gstp3, Gstm6, Gstt1, Serpina1a, Serpina1b, Serpina3m, Hsp90aa1 and Rps14 mRNA levels in AML12 KO cells. In conclusion, the lipid peroxidation system and glutathione mechanism in AML12 cells may be disrupted by the absence of TXNDC5, a novel protein–protein interacting partner of PRDX6 and HSPA9.
A Biomonitoring of Plankton to Assess Quality of Water in the Lakes of Nagpur City

The present study deals with the role of biological parameter especially plankton community and its trophic status to assess water quality of four selected lakes in the Nagpur city. Pollution status of lakes were assessed on the basis of the Palmer’s Pollution Index, Shannon Wiener Index and physico-chemical parameters. A total of 57 genera belonging to 7 groups of phytoplankton and 10 genera belonging to 3 groups of zooplankton were identified from the lakes. Different patterns of dominance and subdominance of indicator plankton community and species along with physico-chemical quality observed confirms the pollution status of the lakes.
Compaction on sand-based putting greens in the Lower Fraser Valley

Core aeration is a cultivation practice used to reduce soil compaction on sand-based putting greens. The objective of this study was to determine the effects of core aeration and play traffic on compaction of sand-based putting greens in the lower Fraser Valley of British Columbia. The experiment was carried out from March 2002 to May 2004 as a randomized complete block design with three replications. The treatments were (i) regular management practices, including core aeration, and high traffic (CA-HT), (ii) regular management practices, no core aeration, and high traffic (NCA-HT), and (iii) reduced management practices, no core aeration, and low traffic (NCA-LT). Similar soil organic matter content and root weight density were found on treatments with and without core aeration with the exception of one date (March 27, 2002). Soil water content of the mat layer on CA-HT was lower relative to NCA-HT on three out of four sampling dates that occurred a month after core aeration. Two months following core aeration soil water contents were similar among all treatments. Water retention was not affected by core aeration or play traffic intensity. Mat layer soil bulk density was lower on NCA-LT then NCA-HT and CA-HT at two out of six sampling dates. There was no difference in soil bulk density of the mat layer between CA-HT and NCAHT, with an exception of one date (June 18, 2003). Soil penetration resistance on NCA-LT was lower relative to the other two treatments at depths below 3 cm. About one month after core aeration soil penetration resistance was lower for CA-HT than NCA-HT treatment. Greater water infiltration rates were observed on NCA-LT than on the other two treatments. Water infiltration rates showed that about a month after core aeration CA-HT had greater infiltration than NCA-HT. This difference disappeared when measurements were taken three and five months after core aeration. Soil penetration resistance and water infiltration measurements indicated that core aeration reduced compaction on sand-based putting greens, but the effects were temporary and differences observed between treatments disappeared within several months following application.
Metallogenic Province and Large Scale Mineralization of Volcanogenic Massive Sulfide Deposits in China

Volcanogenic massive sulfide (VMS) deposits are one of the most important base–metal deposit types in China, are major sources of Zn, Cu, Pb, Ag, and Au, and significant sources for Co, Sn, Se, Mn, Cd, In, Bi, Te, Ga, and Ge. They typically occur at or near the seafloor in submarine volcanic environments, and are classified according to base metal content, gold content, or host‐rock lithology. The spatial distribution of the deposits is determined by the different geological settings, with VMS deposits concentrated in the Sanjiang, Qilian and Altai metallogenic provinces. VMS deposits in China range in age from Archaean to Mesozoic, and have three epochs of large scale mineralization of Proterozoic, Palaeozoic and Mesozoic. Only Hongtoushan Cu–Zn deposit has been recognized so far in an Archaean greenstone belt, at the north margin of the North China Platform. The Proterozoic era was one of the important metallogenic periods for the formation of VMS mineralization, mainly in the Early and Late Proterozoic periods. VMS‐type Cu–Fe and Cu–Zn deposits related to submarine volcanic‐sedimentary rocks, were formed in the Aulacogens and rifts in the interior and along both sides of the North China Platform, and the southern margin of the Yangtze Platform. More than half of the VMS deposits formed in the Palaeozoic, and three important VMS–metallogenic provinces have been recognized, they are Altai–Junggar (i.e. Ashele Cu–Pb–Zn deposit), Sanjiang (i.e. Laochang Zn–Pb–Cu deposit) and Qilian (i.e. Baiyinchang Cu–Zn deposit). The Triassic is a significant tectonic and metallogenic period for China. In the Sanjiang Palaeo–Tethys, the Late Triassic Yidun arc is the latest arc–basin system, in which the Gacun‐style VMS Pb–Zn–Cu–Ag deposits developed in the intra‐arc rift basins, with bimodal volcanic suites at the northern segment of the arc.
Do Kazakh Regions Converge

Even though Kazakhstan is one of the most successful transition countries in Central Asia it has been neglected in the literature on regional convergence. This paper fills this gap with an empirical analysis of the growth process on the regional level using annual gross regional product (GRP) data for the period 1998–2008 for the 16 Kazakh regions. In particular, we look at the sigma- and absolute beta-convergence. Given the growing variation in GRP over time, sigma-convergence cannot be found for Kazakhstan. The data show that there is also no evidence for absolute sigma-convergence. In contrast, the Kazakh regions even seem to diverge.
Valorization of cashew industry wastewater as a carbon and nutrient source for the microbial growth and production of the polyhydroxyalkanoates: A potential biopolymer by Bacillus species

Abstract Wide applications of conventional plastics across the world have made its production inevitable. To avoid the ecocide occurring due to conventional plastics, studies on the production and extraction of renowned biopolymers like polyhydroxyalkanoates (PHAs) are explored. PHA is a family of polyesters naturally produced by bacterial fermentation with the potential to replace conventional hydrocarbon-based polymers. The efficient utilization of industrial discard as renewable feedstocks in the production of eco-friendly products such as bioplastics has been studied. This study focuses on the production of PHA using cashew industry wastewater (CIW). Since cashew industry wastewater (CIW) is rich in phenolic compounds and other sources, this study explores the possibility of eliminating the toxic phenol compounds from the waste by the production of PHA using cashew industry wastewater as a secondary source of carbon by paving the way to eco-friendly process. In this context, PHA-producing bacterium was isolated from wastewater samples collected from cashew industries. The morphological, microscopic, and biochemical characterization revealed that the isolated strain CFM1 is Bacillus sp. The strain CFM1 that gave maximum (30%) PHA in control medium was taken up for further studies with wastewater. The concentration of sucrose in the control production media was replaced with cashew industry wastewater. Wastewater was introduced to the medium at different concentrations (10–100%). As CIW concentration was increased, the sucrose concentration was decreased in the medium accordingly. CFM1 isolates produced 34% PHA with 20% wastewater. The biopolymer produced was characterized by FTIR and NMR.
Cenozoic stratigraphy and geologic history of southwestern Arizona

Recently obtained seismic data and the results of stratigraphic drilling in southwestern Arizona indicate that several alluvium-covered valleys in this area are underlain by more than 3,000 m of Cenozoic deposits. These deposits, with the exception of the marine late Miocene clastic wedge of the Yuma basin and the Pliocene Bouse Formation of the lower Colorado River valley, are the result of continental sedimentation. For the most part, these continental rocks consist of locally derived clastic sediments and lesser amounts of interbedded volcanic rocks and, in some valleys, thick bodies of evaporites. On the basis of their position in the stratigraphic sequence in relation to regional or semiregional unconformities, the Cenozoic sequence of southwestern Arizona was subdivided into an older Unit I and a younger Unit II. The boundary between these two units is a widespread unconformity surface resulting from an important period of subsidence, block-faulting, and erosion that began in late Miocene time (13 to 12 m.y. ago). The two Cenozoic units have been dated and correlated on the basis of radiometric age determination of the inter-bedded extrusive volcanic rocks, on lithologic character, and with the help of seismic interpretation. Sedimentation during early Cenozoic time (Unit I) took place in broad interior depressions under predominantly continental conditions. The late Miocene block-faulting episode changed the geography of southwestern Arizona and gave the area a typical basin-and-range structure of mountain-forming horsts separated by valleys underlain by grabens or half-grabens. The prevailing structural grain trends in a northwest direction. Unit II sediments were deposited in these troughs or grabens during late Cenozoic time. At least two of the five troughs located in the eastern part of the area studied contain thick sequences of evaporites that indicate interior drainage. These evaporites are assigned a late Miocene age on the basis of K-Ar ages for associated extrusive volcanic rocks and by their position in the stratigraphic sequence in relation to the late Miocene block-faulting episode. Exterior drainage systems were developed beginning sometime between 10.5 and 6 m.y. ago and have evolved progressively to give the area its present-day geomorphology.

Assessment of consumers’ knowledge on the safety of vegetables produced in Morogoro urban using low quality water

This study sought to assess the knowledge of consumers on the safety of vegetables produced in Morogoro Urban using Low Quality Water (LQW). The study determined how the knowledge of consumers influenced the perception and preference of various types of vegetables irrigated with LQW. A cross sectional study design was adopted and the 130 respondents were selected using simple random and purposive sampling techniques. Data collection was done using an interview schedule, focus group discussions and direct observation. Simple descriptive statistics, cross tabulations and chisquare test were used to analyse data. The study results indicated that, the vegetable consumers had knowledge that some vegetables in urban Morogoro were irrigated with LQW, but some of them were not sure if the vegetables they consumed were irrigated with LQW. Knowledge had a significant influence on the perception of consumers as it was revealed in this study that, consumers with knowledge that the vegetables were irrigated with LQW washed thoroughly and cooked the vegetables to maintain its safety. The study also found that five types of vegetables; Chinese cabbage, Amaranths, Pumpkin leaves, Sweet potato leaves and Okra were frequently bought and an average of 0.6kg was consumed at household per day. Sweet potato leaves were found to be the most preferred vegetables by respondents among the five types; consumers recognized it’s nutritious regardless of the kind of water used for irrigation. The study concluded that knowledge about the safety of vegetables had influence to the preference and perception of consumers. Based on the findings from this study, it is recommended that Morogoro Municipal Council through Morogoro Rural and Urban Water Supply Authority should set strategies of treating LQW frequently and the community should be assured on its safety before is allowed to use it. The community health officers should provide sanitary education to vegetable vendors and consumers. Also, extension agents should provide education to farmers on improved methods of irrigation.
Collagen Structured Hydration

Collagen is a triple-helical protein unique to the extracellular matrix, conferring rigidity and stability to tissues such as bone and tendon. For the [(PPG)10]3 collagen-mimetic peptide at room temperature, our molecular dynamics simulations show that these properties result in a remarkably ordered first hydration layer of water molecules hydrogen bonded to the backbone carbonyl (bb-CO) oxygen atoms. This originates from the following observations. The radius of gyration attests that the PPG triplets are organized along a straight line, so that all triplets (excepting the ends) are equivalent. The solvent-accessible surface area (SASA) for the bb-CO oxygens shows a repetitive regularity for every triplet. This leads to water occupancy of the bb-CO sites following a similar regularity. In the crystal-phase X-ray data, as well as in our 100 K simulations, we observe a 0-2-1 water occupancy in the P-P-G triplet. Surprisingly, a similar (0-1.7-1) regularity is maintained in the liquid phase, in spite of the sub-nsec water exchange rates, because the bb-CO sites rarely remain vacant. The manifested ordered first-shell water molecules are expected to produce a cylindrical electrostatic potential around the peptide, to be investigated in future work.
SEISMIC IMAGING OF SHALLOW REFLECTORS IN THE EASTERN KAPUSKASING STRUCTURAL ZONE, WITH CORRECTION OF CROSSDIP ATTITUDES

Cascaded processes of crossdip correction and residual statics are tested and applied in the reprocessing of regional data from LITHOPROBE Kapuskasing Transect line 2. The objective was to improve seismic imaging of shallow, gently dipping reflectors in the eastern Kapuskasing structural zone (KSZ), a thrusted slice of Archean middle to lower crust. This focusing strategy proved to be very effective in improving the image of the reflected energy and in identifying a set of conformally dipping reflectors whose true crossdip is estimated to be approximately 17° NW. The estimated crossdips for a reflective, compositionally layered zone and for the basal thrust, the Ivanhoe Lake Fault zone (ILFZ), support the previously estimated average dip of 15°–20°.
Valuation of Swing Options in Electricity Commodity Markets

Although electricity is considered to be a commodity, its price behavior is remarkably different from most other commodities or assets on the market. Since power can hardly be stored physically, the storage-based methodology, which is widely used for valuing commodity derivatives, is unsuitable for electricity. Therefore, new approaches are required to understand and reproduce its price dynamics. Concurrently, the demand for derivative instruments has grown and new types of contracts for energy markets have been introduced. Swing options, in particular, have attracted an increasing interest, offering more flexibility and reducing exposure to strong price fluctuations. In this thesis, we propose a mean-reverting model with seasonality and double exponential jumps. It is able to accurately reproduce the behavior and main peculiarities of electricity's spot prices. With this model, we can characterize the swing option value as a solution to a partial integro-differential complementarity problem, which we solve numerically. In the last part of the thesis, we present a more complex type of swing options, in which we also include variable electricity volumes in the contract. This formulation leads to a two-dimensional Hamilton-Jacobi-Bellman (HJB) equation. By applying the method of characteristics, this problem is simplified to a sequence of one dimensional HJB equations, which are solved numerically by using a similar approach as before.
Structural clues to the origin of refractory metal alloys as condensates of the solar nebula

Abstract– Alloys of the refractory metals Re, Os, W, Ir, Ru, Mo, Pt, and Rh with small amounts of Fe and Ni are predicted to be one of the very first high‐temperature condensates in a cooling gas of solar composition. Recently, such alloy grains were found in acid‐resistant residues of the Murchison CM2 chondrite. We used focused ion beam (FIB) preparation to obtain electron‐transparent sections of 15 submicrometer‐sized refractory metal nuggets (RMNs) from the original Murchison residue. We studied their crystallography, microstructures, and internal compositional variations using transmission electron microscopy (TEM). Our results show that all RMNs studied have hexagonal close‐packed (hcp) crystal structures despite considerable variations of their bulk compositions. Crystallographic superstructures or signs of spinodal decomposition are absent and defect microstructures are scarce. Internally, RMNs are compositionally homogeneous, with no evidence for zoning patterns or heterogeneities due to exsolution. Many RMNs show well‐defined euhedral crystal shapes and all are nearly perfect single crystal. Our findings are consistent with a direct (near‐) equilibrium condensation of refractory metals into a single alloy at high temperature in the solar nebula as predicted by current condensation models. We suggest that this alloy is generally hcp structured due to an extended ε‐phase field in the relevant multicomponent alloy system. The high degree of structural perfection and compositional homogeneity is attributed to high defect energies, high formation temperatures, slow cooling rates, small grain sizes, and rapid internal diffusion.
