SUMMARY
Purpose: This double blind, randomized clinical trial compared the postoperative sensitivity of the placement technique (incremental and bulk fill) in posterior composite resin restorations bonded with two different adhesive strategies (self-etch and etch-and-rinse).
Methods: Posterior dental cavities of 72 participants (n=236), with a cavity depth of at least 3 mm, were randomly divided into four groups. The restorations were bonded using either the etch-and-rinse Tetric N-Bond (Ivoclar Vivadent) or the self-etch Tetric N-Bond SE (Ivoclar Vivadent). The composite resin Tetric N-Ceram Bulk Fill (Ivoclar Vivadent) was placed either incrementally or using the bulk-fill technique. Two experienced and calibrated examiners evaluated the restorations using World Dental Federation criteria after one week of clinical service. Spontaneous postoperative sensitivity was assessed using a 0-4 numerical rating scale and a 0-10 and 0-100 visual analog scale up to 48 h after the restorative procedure and after one week.
Results: The risk (p&gt;0.49) and intensity of spontaneous postoperative sensitivity (p&gt;0.38) was not affected by the adhesive strategy or the filling technique. The overall risk of postoperative sensitivity was 20.3% (95% confidence interval 15.7-25.9) and typically occurred within 48 hours after the restorative procedure.
Conclusions: The overall risk of immediate postoperative sensitivity was 20.3% and was not affected by either the adhesive strategy (etch-and-rinse/self-etch) or the filling technique (incremental/ bulk).
Equatorial ionospheric plasma drifts velocities using radar observations
Authors: Chapagain Narayan P 
Published: November 2016

This study presents the experimental results of the equatorial ionospheric plasma drift zonal velocity obtained from Incoherent Scatter Radar (ISR) observations for 6 selective days in 2011 from Jicamarca, Peru. Our results indicate that the daytime drifts are westward with peak values mostly below ~50 m/s, while the night time drifts velocities are eastward, with a maximum value up to 120 m/s at around local midnight hours. The drift velocity decreases during post-midnight hours and starts to reverse westward in early morning hours. Our plasma drifts results are in good agreement with results from previous radar studies and other measurement techniques.

Authors: Raut Nabin Kumar , Lamichhane Hari Prasad 
Published: November 2016

The present work enumerates detailed computational investigation into the IR spectra in gas phase and in solvent of 1, 4- Benzoquinone family (benzoquinone (BQ), duroquinone (DQ), plastoquinone (PQ), ubiquinone (UQ), and dimethoxy dimethyl benzoquinone (MQo)). In the spectra of BQ, PQ, and DQ, we observed separate intense carbonyl (C=O) and C=C bands respectively around 1730 cm-1 (intense), 1645 cm-1 (weak). On the other hand, for UQ and MQo, three prominent bands around 1652, 1703, and 1733 cm-1 were observed, where two C=O modes were uncoupled but one of the carbonyl is strongly coupled with C=C vibrations. The additional methyl groups downshift the intense carbonyl bands and upshift C=C mode frequencies. The carbonyl modes further downshifted in the solvent phase calculation.BIBECHANA 14 (2017) 66-76

Published: November 2016

Viscosity and surface tension measurements of cetyltrimethylammonium bromide (CTAB) in presence and absence of Na2SO4 and MgSO4 in aqueous media are reported. The results showed an increase in viscosity with increase in concentration of cetyltrimethylammonium bromide in presence and absence of salts where as the decrease in surface tension with increase in concentration of cetyltrimethylammonium bromide in presence and absence of salts. The viscosity of CTAB was observed lowest in pure water and increases in presence of MgSO4 and then more increases in presence of Na2SO4 where as the surface tension of CTAB was observed highest in pure water and decreases in presence of Na2SO4 and then more decreases in presence of MgSO4.The critical micelle concentration (cmc) of CTAB decreases in presence of salts in both viscosity and surface tension measurements. The decreasing cmc of CTAB are found to be more in the presence of Na2SO4 in comparison with the presence of MgSO4 for both measurements. The graphs of viscosity versus log[C] and the surface tension versus log[C] are used in determining the critical micelle concentration (cmc). BIBECHANA 14 (2017) 77-85

Authors: Mahasetha Vinod Kumar 
Published: November 2016

Present paper describes primary productivity of Mahakali river at four stations. The two years mean of net primary production was 96.80 mgC/m3/day. The net primary production value of Mahakali river was less due to the low water temperature and less phytoplanktonic growth. Two years mean value of gross primary production of Mahakali river was 176.29 mgC/m3/day, which is less than lentic water. It shows that the river is oligotrophic but developing a tendency as going towards mesotrophic.BIBECHANA 14 (2017) 98-102

Published: November 2016

Background and Objectives: The prevention and treatment of peptic ulcers has become an important challenge in the current medicine world. Modern progress in novel drug delivery system aims to improve the efficacy of the drug molecule by formulating a dosage form of RHCL. One of the most feasible approaches for achieving a prolonged and predictable drug delivery profile in GI tract is to control the gastric residence time. Therefore, a multi-unit gastro retentive dosage form of RHCL capable of floating on simulated gastric fluid for more than 12 hours was formulated and evaluated.Materials and Methods: Nine batches of the light liquid paraffin entrapped emulsion gel beads were prepared by a new emulsion gelation technique using sodium alginate and xanthan gum as polymers. The polymeric solution was extruded into Calcium chloride solution by the use of 21G needles. Morphology of beads, drug content, drug entrapment efficiency, floating lag time and buoyancy were studied. Compatibility study of Ranitidine HCl with polymers used in the formulation was performed using DSC and FT-IR.Results: Mean surface diameter were between 1.220 ± 2.259% (F1) to 1.230 ± 2.316% (F9) and floating lag time were between 6 minute (F9) to 11 minute (F1). All formulations were buoyant for more than 12 hours in simulated gastric fluid at 37ºC. The drug content and drug entrapment efficiency among the formulations were between 17.48%~19.68% and 71.06% ~84.32% respectively. Formulation F1 showed lowest drug content and drug entrapment efficiency while F9 showed highest drug content and drug entrapment efficiency. F4 showed most acceptable sustained drug release profile.Conclusion: The gastro retentive drug delivery system designed as floating beads was found to be satisfactory drug delivery system for Ranitidine HCl to improve the bioavailability of the drug.

Published: November 2016

Background and Objectives: In developing countries like Nepal, the oral health system is currently in transition phase facing a high prevalence of dental caries. It has significant social impact in important life activities which hinders the achievement and ma intenance of good oral health due to lack of dental awareness in all age groups. Streptococcus mutans is the most predominant organism to cause dental caries. Therefore, the present study was designed to determine the prevalence of dental caries and to identify its etiology among adolescence.Material and Methods: This cross-sectional study was carried by following Standard protocols of Bergey’s Manual of Systematic Bacteriology to isolate and identify the organism. The data was analyzed using SPPS 17.0 and Microsoft excels 2007 which was considered as statistically significant at p-value < 0.05.Results: The prevalence of dental caries in adolescent was found to be 33%. The highest numbers of patients having dental caries were in the age group of 15-19 in female (66.32%) than male (39.70%). Bacterial growth was observed more in female (75.60%) than male (24.39%) which was found to be statistically significant (p=0.0001). S. mutans was found as the most important cause of dental caries. Maxillary region of tooth were more vulnerable to dental caries than mandibular region of tooth. Most of the respondents had once per day brushing habit without fluoridated dentrifice containing tooth paste.Conclusion: The prevalence of dental caries was found one third of total. S.mutans was the main causes of dental caries and molars tooth are more affected than others.Janaki Medical College Journal of Medical Sciences (2015) Vol. 3 (2): 29-37

Authors: Singh A K 
Published: November 2016

Background and Objectives: The deltoid ligament is a very tough and strong ligament of the ankle joint. Different studies had been done by many investigators to find out its involvement in different types of ankle trauma and diseases. There is scanty of paper in the study of morphology of deltoid ligament among Kyrgyz (Mangolion race) context, this study was carried out to fill this gap in the literature.Material and Methods: Twenty-five limbs from cadevar and 32 of fresh dead (from freezer) bodies were selected for the study. Following the dissection, the parts, borders and the attachments of the superficial fibres of the ligament was identified and their attachments were established by inspection, palpation and by slight evertion of the ankle joint. The extents of their proximal and distal attachment were also measured. Mid way between the proximal and distal attachment of the anterior and posterior border ligament point were plotted through which the breadth of the respective ligament was measured again the vernier calipers. Data were entered in Excel and SPSS and were analyzed.Results: The result showed that the longest ligament was the tibionavicular and the shortest was the tibiotalar ligament. Similarly the broadest ligament was found to be the tibiotalar and the narrowest was the tibiocalcaneal ligament. There was no significant variation found in the length, breadth and the attachment of the ligament in terms of the sex and side of the limb. The interesting result which was obtained from the correlation coefficient was that the lengths of the tibiocalcaneal and tibiotalar ligaments were found to be increased with increasing age.Conclusion: The lengthening of the tibiocalcaneal and tibiotalar ligament, increased breadth of tibiotalar ligament and increased extent of origin of the ligament in old age which was evident in this study.

ABSTRACT
Precision uvbyCaHβ photometry of the metal-deficient, old open cluster NGC 2506 is presented. The survey covers an area of

and extends to

for b − y and Hβ and to

for c
1 and hk. For V brighter than 16.0, photometric scatter among the indices leads to the recovery of six known variables within the cluster core and five new variables in the outer

of the survey field. Proper motions, radial velocities, and precise multicolor indices are used to isolate a highly probable sample of cluster members from the very rich color–magnitude diagram. From 257 highly probable members at the cluster turnoff, we derive a reddening estimate of

(

), where the errors refer to the internal standard errors of the mean. [Fe/H] is derived from the A/F dwarf members using both m
1 and hk, leading to [Fe/H] = −0.296 ± 0.011 (sem) and −0.317 ± 0.004 (sem), respectively. The weighted average, heavily dominated by hk, is [Fe/H] = −0.316 ± 0.033. Based on red giant members, we place an upper limit of ±0.010 on the variation in the reddening across the face of the cluster. We also identify two dozen potential red giant cluster members outside the cluster core. Victoria–Regina isochrones on the Strömgren system produce an excellent match to the cluster for an apparent modulus of

and an age of 1.85 ± 0.05 Gyr.

ABSTRACT
We report the discovery of K2-98b (EPIC 211391664b), a transiting Neptune-size planet monitored by the K2 mission during its Campaign 5. We combine the K2 time-series data with ground-based photometric and spectroscopic follow-up observations to confirm the planetary nature of the object and derive its mass, radius, and orbital parameters. K2-98b is a warm Neptune-like planet in a 10 day orbit around a V = 12.2 mag F-type star with M

ABSTRACT
Using Hubble Space Telescope Cosmic Origins Spectrograph observations of 89 QSO sightlines through the Sloan Digital Sky Survey footprint, we study the relationships between C iv absorption systems and the properties of nearby galaxies, as well as the large-scale environment. To maintain sensitivity to very faint galaxies, we restrict our sample to

, which defines a complete galaxy survey to

or stellar mass

. We report two principal findings. First, for galaxies with impact parameter

, C iv detection strongly depends on the luminosity/stellar mass of the nearby galaxy. C iv is preferentially associated with galaxies with

lower-mass galaxies rarely exhibit significant C iv absorption (covering fraction

for 11 galaxies with

). Second, C iv detection within the

population depends on environment. Using a fixed-aperture environmental density metric for galaxies with ρ < 160 kpc at

, we find that

(8/14) of galaxies in low-density regions (regions with fewer than seven

galaxies within 1.5 Mpc) have affiliated C iv absorption; however, none (0/7) of the galaxies in denser regions show C iv. Similarly, the C iv detection rate is lower for galaxies residing in groups with dark matter halo masses of

. In contrast to C iv, H i is pervasive in the circumgalactic medium without regard to mass or environment. These results indicate that C iv absorbers with

trace the halos of

galaxies but also reflect larger-scale environmental conditions.

ABSTRACT
Star formation is primarily controlled by the interplay between gravity, turbulence, and magnetic fields. However, the turbulence and magnetic fields in molecular clouds near the Galactic center may differ substantially compared to spiral-arm clouds. Here we determine the physical parameters of the central molecular zone (CMZ) cloud G0.253+0.016, its turbulence, magnetic field, and filamentary structure. Using column density maps based on dust-continuum emission observations with ALMA+Herschel, we identify filaments and show that at least one dense core is located along them. We measure the filament width

and the sonic scale

of the turbulence, and find

. A strong velocity gradient is seen in the HNCO intensity-weighted velocity maps obtained with ALMA+Mopra. The gradient is likely caused by large-scale shearing of G0.253+0.016, producing a wide double-peaked velocity probability distribution function (PDF). After subtracting the gradient to isolate the turbulent motions, we find a nearly Gaussian velocity PDF typical for turbulence. We measure the total and turbulent velocity dispersion,

and

, respectively. Using magnetohydrodynamical turbulence simulations, we find that G0.253+0.016's turbulent magnetic field

is only

of the ordered field component. Combining these measurements, we reconstruct the dominant turbulence driving mode in G0.253+0.016 and find a driving parameter of

, indicating solenoidal (divergence-free) driving. We compare this to spiral-arm clouds, which typically have a significant compressive (curl-free) driving component (

). Motivated by previous reports of strong shearing motions in the CMZ, we speculate that shear causes the solenoidal driving in G0.253+0.016 and show that this reduces the star-formation rate by a factor of 6.9 compared to typical nearby clouds.

Published: December 2016

Objective.To develop a genotype-based ankylosing spondylitis (AS) risk prediction model that is more sensitive and specific than HLA-B27 typing.Methods.To develop the AS genetic risk scoring (AS-GRS) model, 648 individuals (285 cases and 363 controls) were examined for 5 copy number variants (CNV), 7 single-nucleotide polymorphisms (SNP), and an HLA-B27 marker by TaqMan assays. The AS-GRS model was developed using logistic regression and validated with a larger independent set (576 cases and 680 controls).Results.Through logistic regression, we built the AS-GRS model consisting of 5 genetic components: HLA-B27, 3 CNV (1q32.2, 13q13.1, and 16p13.3), and 1 SNP (rs10865331). All significant associations of genetic factors in the model were replicated in the independent validation set. The discriminative ability of the AS-GRS model measured by the area under the curve was excellent: 0.976 (95% CI 0.96–0.99) in the model construction set and 0.951 (95% CI 0.94–0.96) in the validation set. The AS-GRS model showed higher specificity and accuracy than the HLA-B27–only model when the sensitivity was set to over 94%. When we categorized the individuals into quartiles based on the AS-GRS scores, OR of the 4 groups (low, intermediate-1, intermediate-2, and high risk) showed an increasing trend with the AS-GRS scores (r2= 0.950) and the highest risk group showed a 494× higher risk of AS than the lowest risk group (95% CI 237.3–1029.1).Conclusion.Our AS-GRS could be used to identify individuals at high risk for AS before major symptoms appear, which may improve the prognosis for them through early treatment.

Authors: Friend Mary Louanne , Friend Richard D. , Ford Cassandra , Ewell Patrick J. 
Published: November 2016

Background:
The purpose of this mixed-methods study was to evaluate the effects of an innovative critical care interprofessional education intervention on prelicensure nursing and medical students at a large public university. The class provided opportunities for students to (a) explore stereotypes about each respective profession, (b) examine the occurrence and effects of interprofessional conflict in high-acuity areas, and (c) explore conflict resolution techniques while learning how to perform critical care procedures as a team.

Method:
A nonequivalent control group design with pretest, posttest, and focus group interviews were used.

Results:
Data analyses indicated no subscales and total scores were significantly different across time or between groups. However, focus group analyses indicated that changes did occur.

Conclusion:

The findings suggest that students experience interprofessional conflict in clinical settings, yet lack the confidence and skills to effectively mitigate these behaviors. Ongoing studies to measure student empowerment and their intentions to practice collaboratively before and after graduation are recommended. [
