Adolescent Perceptions of Dating Violence: A Qualitative Study
Authors: Taylor Sarah , Calkins Carrie A. , Xia Yan , Dalla Rochelle L.
Published: August 2017

Scholars have identified dating violence as a public health issue among adolescents. Yet, minimal research has detailed adolescents’ perceptions of dating violence, specifically gender differences in perceptions. Research suggests that in order for dating violence prevention and intervention to be effective, services need to be delivered in a manner that is understood by adolescents. Therefore, this study used a qualitative phenomenology study to investigate adolescents’ perceptions of dating violence, including gender differences in adolescents’ perceptions. Thirty adolescents between the ages of 14 and 19 from a Midwest public high school participated in focus groups. Focus group participants were asked semistructured interview questions regarding the definition of dating violence, risk and protective factors for dating violence, support for victims and perpetrators, and prevention efforts. Data were analyzed using qualitative content analysis methods, and common themes were identified. Adolescents’ language revealed gender differences in perceptions toward dating violence. Males perceive dating violence through action, perpetration, and physical consequences. Females discuss dating violence by relating to the victim and the victim’s emotions. Although gender differences existed in participants’ perceptions, both males and females explained that dating violence is more often perpetrated by females, despite the view from society that males are more likely to perpetrate dating violence. Findings suggest that schools, practitioners, and policy makers are not meeting the needs of adolescents in regard to dating violence prevention and intervention. Prevention and intervention efforts could be improved by delivering education and services using language that adolescents find relevant. Findings also suggest that adolescents may benefit from prevention and intervention with gender specific components.
Who Helps the Helpers? Social Support for Rape Crisis Advocates

Published: August 2017

Secondary exposure to trauma may have negative effects on rape victim advocates’ well-being. Self-care can help to mitigate these negative effects on advocates’ well-being, and prior research suggests that social support is an especially important aspect of advocates’ self-care. However, there is a lack of research on how rape crisis advocates access and receive social support in relationship to their advocacy work. Therefore, semistructured qualitative interviews were conducted with 15 rape crisis advocates who volunteered for a rape crisis center in Chicago to understand how they accessed social support from informal and formal support providers, and when they did receive support, what was helpful versus unhelpful. Data were analyzed using thematic content analysis. Results revealed that many advocates were able to seek out and receive positive instrumental and emotional social support that nurtured them and their work. However, advocates also experienced a variety of barriers to obtaining positive support from informal support providers, including fear of burdening providers and a reluctance or lack of preparedness of their support providers to speak about the issue. Advocates emphasized the need for rape crisis centers to provide resources for their informal social support systems in order to encourage helpful responses. In addition, advocates praised the rape crisis center for its built-in formal support structures, but also encouraged the organization to seek broader representation of persons from minority backgrounds among their advocates and mentors. Implications and future directions for research and rape crisis centers are also discussed. The present study highlights the importance of social support systems for advocates and potential barriers that may be addressed to reduce service provider burnout and vicarious trauma.

Published: August 2017

Background

Integrating health literacy into primary care institutional policy and practice is critical to effective, patient centered health care. While attributes of health literate organizations have been proposed, approaches for strengthening them in healthcare systems with limited resources have not been fully detailed.

Methods

We conducted key informant interviews with individuals from 11 low resourced health care organizations serving uninsured, underinsured, and government-insured patients across Missouri. The qualitative inquiry explored concepts of impetus to transform, leadership commitment, engaging staff, alignment to organization wide goals, and integration of health literacy with current practices.

Findings

Several health care organizations reported carrying out health literacy related activities including implementing patient portals, selecting easy to read patient materials, offering community education and outreach programs, and improving discharge and medication distribution processes. The need for change presented itself through data or anecdotal staff experience. For any change to be undertaken, administrators and medical directors had to be supportive; most often a champion facilitated these changes in the organization. Staff and providers were often resistant to change and worried they would be saddled with additional work. Lack of time and funding were the most common barriers reported for integration and sustainability. To overcome these barriers, managers supported changes by working one on one with staff, seeking external funding, utilizing existing resources, planning for stepwise implementation, including members from all staff levels and clear communication.

Conclusion

Even though barriers exist, resource scarce clinical settings can successfully plan, implement, and sustain organizational changes to support health literacy.
Teacher’s ethnic teasing: Playing with ambiguity and exploiting in-group communication
Authors: Artamonova Olga
Published: August 2017

This article discusses the issue of ethnic teasing used by a teacher and his students in a multiethnic classroom of a German middle school. The teacher and his students exploit the resources of the racist discourse for multiple in-group rituals. Based on a school ethnography and conversation analysis, this case study attempts to interpret the teasing practices, which are performed in a classroom where ethnicity matters greatly. The teasing interactions here, questioned in the local context, seem to be a part of a working consensus, helping to regulate interpersonal relations in class. These vague and risky practices infringe the politeness norms: they are based on a daily face-attack ritualization through which a partial weakening of the discriminatory effect might be achieved.
Trends in school library programs 2007–2012: Analysis of AASL’s School Libraries Count! data sets
Authors: Farmer Lesley S.J. , Safer Alan M.
Published: August 2017

This study used the AASL School Libraries Count! data sets to examine school library program trends within the 2009–2012 time frame, and identify possible relationships between contributing factors across the four years and across the four geographic regions. Several statistical tests were applied to the coded AASL survey data sets longitudinally and by region: descriptive statistics, correlation analysis, chi-squared independence tests, hypothesis testing of differences in proportions, and analysis of variance. The data reveal a variegated picture of school library programs in terms of staffing, resources, and activities – from state to state, by region, and by school level. In general, high schools fared best relative to elementary and middle schools, and the West fared the worst relative to the other regions. The findings highlight the impact of school level, poverty status, and governmental spending decisions on school library program staffing, resources and activities. The school librarian’s activities also correlate with library resources and their usage.
Mediatising Political Rhetoric
Authors: Abbas Qaisar
Published: August 2017

The mediatisation of politics has been a dominant theory in the field of political communication for some time, proposing that the mass media in democratic societies tend to dominate the political process. This research intends to explore the media-politics nexus as part of the protest campaign in 2014 in Pakistan, also known as the long march. Specifically, it analyses dynamics of the political rhetoric of protesting leaders and dimensions of the two selected TV talk shows. Using textual analysis as research methodology, this article concludes that by transforming the political theatre into a media theatre, the talk shows effectively mediatised the long march. TV news became part of the political process, rather than covering it objectively, either by supporting or opposing the long march. The two top political leaders of the long march voluntarily adopted media logic as a rhetorical strategy to offer a readymade product for media coverage.
Free in-plane vibration of curved beam structures: A tutorial and the state of the art
Authors: Yang F , Sedaghati R. , Esmailzadeh E.
Published: August 2017

The study of free in-plane vibration of curved beams, using different beam theories, is more challenging than that of straight beams, since the structural deformations in curved beams depend not only on the rotation and radial displacements, but also on the coupled tangential displacement caused by the curvature of structures. A critical review of the publications on the free in-plane vibration of curved beams to demonstrate the state of the art has been presented. The governing differential equations of motion for the curved beams, based on different hypotheses (including and excluding the axial extensity, rotary inertia and the shear deformation), were discussed and different approaches to solve the developed equations of motion have been identified. Finally, a systematic comparison of the dynamic properties of curved beams evaluated with various forms of curvatures based on different hypotheses were presented.
Immunohistochemical Staining for Uroguanylin, a Satiety Hormone, is Decreased in Intestinal Tissue Specimens From Female Adolescents With Obesity

Published: August 2017

Gastrointestinal tract–secreted satiety hormones play a significant role in one of the largest health-care challenges for children and adults, obesity. Recent studies in mice identified a novel role for uroguanylin, the endogenous intestinal hormone that binds guanylyl cyclase C (GUCY2C), in regulating satiety via a gut-brain signaling pathway. Mice bred without GUCY2C receptors over-ate and developed obesity. We hypothesized that intestinal uroguanylin expression in pediatric patients with obesity would be lower than patients without obesity, and we attempted to examine the difference with immunohistochemistry. Retrospective chart review of gastrointestinal endoscopic procedures at an academic children’s hospital identified patients with normal pathology findings on biopsy. Children aged 8–17 were included in the review; we analyzed biopsy samples from 20 matched pairs that differed only by body mass index (BMI)-for-age (average: 25%–75% vs. high: >95%). Biopsies of the duodenum, terminal ileum, ascending colon, and descending colon were subjected to immunohistochemistry for GUCY2C, uroguanylin, and the endogenous colonic hormone, guanylin. Intensity staining of all specimens was scored by a blinded pathologist. The overall staining intensity for females with high BMI-for-age was less for uroguanylin and guanylin as compared to average BMI-for-age females while GUCY2C staining was equal. Males did not exhibit different staining intensities for uroguanylin or guanylin. More matched female pairs had greater uroguanylin and guanylin staining in the average BMI-for-age cohort. The intestinal expression of uroguanylin, a key satiety hormone, appears to be diminished in female pediatric patients in the setting of obesity.
Health trends in the wake of the financial crisis—increasing inequalities?
Authors: Nelson Kenneth , Tøge Anne Grete
Published: August 2017

Aim: The financial crisis that hit Europe in 2007–2008 and the corresponding austerity policies have generated concern about increasing health inequalities, although impacts have been less salient than initially expected. One explanation could be that health inequalities emerged first a few years into the crisis. This study investigates health trends in the wake of the financial crisis and analyses health inequalities across a number of relevant population subgroups, including those defined by employment status, age, family type, gender, and educational attainment. Methods: This study uses individual-level panel data (EU-SILC, 2010–2013) to investigate trends in self-rated health. By applying individual fixed effects regression models, the study estimates the average yearly change in self-rated health for persons aged 15–64 years in 28 European countries. Health inequalities are investigated using stratified analyses. Results: Unemployed respondents, particularly those who were unemployed in all years of observation, had a steeper decline in self-rated health than the employed. Respondents of prime working age (25–54 years) had a steeper decline than their younger (15–24) and older (55–64) counterparts, while single parents had a more favorable trend in self-rated health than dual parents. We did not observe any increasing health inequalities based on gender or educational attainment. Conclusions: Health inequalities increased in the wake of the financial crisis, especially those associated with employment status, age, and family type. We did not observe increasing health inequalities in terms of levels of educational attainment and gender.
Teachers’ Knowledge About Intellectual Giftedness: A First Look at Levels and Correlates
Authors: Heyder Anke , Bergold Sebastian , Steinmayr Ricarda
Published: August 2017

Evidence-based knowledge about intellectual giftedness is important for identifying, counseling, and fostering intellectually gifted students. How much teachers actually know about intellectual giftedness is unclear because previous studies have relied solely on self-reports. This study aimed to: (a) develop a test for the assessment of teachers’ knowledge about intellectual giftedness defined as an intellectual capacity significantly above average, the identification of giftedness, and characteristics of gifted students; and (b) inspect some correlates of teachers’ performance on a knowledge test. The final version of the test comprised 38 items and a true–false–do-not-know response format. Sixty-three German secondary school teachers completed the test. On average, teachers answered 26.8% of the items correctly, 34.7% incorrectly, and 38.1% with “do not know.” The higher teachers’ rate of misconceptions, the more negative was their attitude toward fostering gifted students. Personal contact with the gifted was correlated with subjective knowledge but not with assessed knowledge. The results stress the importance of intellectual giftedness as a psychological topic to be addressed during teacher education.

Published: August 2017

Painful peripheral neuropathy is a severe side effect in oxaliplatin therapy that compromises cancer patients' quality of life. However, its underlying pathogenic mechanisms remain largely unknown. Here, we found that intraperitoneal consecutive administration of oxaliplatin significantly increased excitability of small diameter dorsal root ganglion neurons and induced thermal hyperalgesia in rats. Furthermore, the CX3CL1 expression was significantly increased after oxaliplatin treatment, and intrathecal injection of a neutralizing antibody against CX3CL1 markedly attenuated the enhanced excitability of dorsal root ganglion neurons and thermal hyperalgesia. Importantly, the upregulated CX3CL1 is mediated by the NF-κB signaling pathway, as inhibition of NF-κB p65 activation with pyrrolidine dithiocarbamate or p65 siRNA inhibited the upregulation of CX3CL1, the enhanced excitability of dorsal root ganglion neurons, and thermal hyperalgesia induced by oxaliplatin. Further studies with chromatin immunoprecipitation found that oxaliplatin treatment increased the recruitment of NF-κB p65 to the CX3Cl1 promoter region. Our results suggest that upregulation of CX3CL1 in dorsal root ganglion mediated by NF-κB activation contributes to the peripheral sensitization and chronic pain induced by oxaliplatin administration.

Published: August 2017

Pigmented villonodular synovitis (PVNS) is an uncommon entity involving articular or extra-articular tissues and maybe localized or diffuse in extent. The knee is by far the commonest joint to get involved. Localized PVNS of the knee can occur in any location but its confinement to the posterior compartment is infrequent. We present our experience of managing localized posterior compartment PVNS of the knee. There were 10 patients (7 males and 3 females) with average age of 33 years. These patients had symptoms of pain, locking, or swelling for a mean of 13.9 years before diagnosis. All the patients underwent arthroscopic synovectomy without adjuvant therapy, and PVNS was proven on histopathology. At an average follow-up of 23 months, no patient had recurrence of symptoms. The average International Knee Documentation Committee (IKDC) score at last follow-up was 85.21. Magnetic resonance imaging evaluation at final follow-up did not reveal any residual disease or recurrence in any patient.
Older Adults at Risk for Atrial Fibrillation Lack Knowledge and Confidence to Seek Treatment for Signs and Symptoms
Authors: McCabe Pamela J. , Barton Debra L. , DeVon Holli A.
Published: August 2017

Early detection of atrial fibrillation (AF) is crucial for averting AF-related stroke and heart failure, but treatment is delayed when AF is not recognized. The critical need for early detection and treatment requires education to promote AF awareness. Knowledge deficits, attitudes, and beliefs about AF that should be addressed to improve awareness and reduce treatment-seeking delay in older adults at risk for developing AF have not been well documented. The purpose of this study was to describe knowledge, treatment-seeking attitudes, and beliefs about AF in adults ≥65 years old and identify demographic characteristics associated with knowledge, attitudes, and beliefs. Patients with no history of AF recruited from an academic medical center were interviewed using the Knowledge, Attitudes, and Beliefs about Atrial Fibrillation Survey. Data were analyzed using descriptive statistics and independent t tests. Participants ( N = 180) were 63% male with a mean age of 73.7 ± 6.0 years, and 52% held ≥ 4-year college degree. About one third could not identify common symptoms of AF including palpitations (31%), chest pain (36%), dyspnea (30%), and fatigue (35%). A majority (84%) lacked confidence to recognize AF, and 58% were not sure when they should seek care for AF symptoms. Nearly a third (32%) believed palpitations are always present with AF, and 74% believed that low energy would not be their only symptom of AF. Higher scores for AF Symptom Knowledge ( p = .02) were observed in females, and General Knowledge about AF was greater for younger participants ( p < .001). Participants lacked knowledge and confidence to aid decision-making for treatment-seeking for symptoms of AF and held inaccurate beliefs about AF that could hinder early treatment-seeking. Programs to promote AF awareness should explain the spectrum of symptoms that may be manifested by AF and include action plans for responding to symptoms.

Published: August 2017

Understanding the contexts in which young children develop is essential for promoting positive outcomes. In this study, the researchers used focus groups to investigate the perspectives of 14 parents across rural North Carolina concerning ecocultural features that enhanced or prevented sustained engagement with their infants and toddlers with disabilities or delays. Parents perceived ecocultural features as having either a positive influence or no influence on their engagement. They also reported actively making accommodations to interrupt potential barriers to engagement. Results highlight the adaptive capacities of families in rural communities and delineate community resources that might contribute to sustainable intervention practices.

An attitude of gratitude comes easily when thinking back to my time as a student at Colorado School of Mines. After all, Mines is where I developed the strong technical foundation I draw from daily, where I was recruited by Chevron into my dream job, and where I met many of my closest friends, best of all my husband. Then, of course, there is the magnificent scenery, the collaboration with world-renowned faculty, and the unique experience that is E-Days. While there are many things to be grateful for, the one that stands out in my mind is the support of the SEG Foundation and its generous donors. They empowered me to focus on the things I valued most rather than on the stress of paying for college. In an effort to give back to the Foundation and give forward to future geophysicists, I joined the SEG Scholarship committee in mid-2016. My transition from scholarship recipient to committee member was as rewarding as it was educational.

Building a model with realistic pore pressures: Modifying the SEAM Phase I subsalt model
Authors: Salazar Simone , Hantschel Thomas , Nozanda Farliz , Fehler Michael
Published: August 2017

Predrill pore-pressure prediction, particularly in overpressured reservoirs, is of paramount importance for hazard avoidance in deepwater basins like those in the Gulf of Mexico. The SEG Advanced Modeling (SEAM) Pore Pressure Prediction project has been developing a model for a region of the Gulf of Mexico that can be used for seismic simulation to generate a seismic data set for use in testing pore-prediction methodologies. The approach was to modify the deepwater model developed for the SEAM Phase I project to include a realistic pore-pressure distribution. The methodology for determining the pore pressures was to use basin simulation with the Phase I model as a basis. We experimented with a range of parameters and pore-pressure-generation mechanisms to better understand their impact on the final distribution of predicted pore pressures. The experiments and results obtained from them will be described. Following completion of the basin simulation, a rock-physics model was developed to transform the geology and derived pore pressures into anisotropic elastic values that were then used for seismic simulation.

Published: August 2017

SEAM Time Lapse, a collaborative technical project of SEG and the Society of Petroleum Engineers, created integrated geologic, reservoir, and geophysical models to simulate temporal changes in the geometry and physical properties of a complex reservoir with the detail and accuracy needed to explain the subtle effects seen in time-lapse surveys of real oil fields. The geologic model consisted of 2 billion grid cells, representing a region 12.5 × 12.5 km in horizontal extent and 5 km in depth and including a 420 m thick reservoir with upper and lower units separated by an impermeable shale layer and offset by faults. Deepwater clastic turbidite channels and lobes were used to create a typical shallow Gulf of Mexico reservoir that also can serve as an analogue of other turbidite fields around the world. Stratigraphic detail within the reservoir was retained in the simulation model through careful finite-element meshing. The reservoir simulation computed the fully coupled three-phase fluid flow and linear geomechanical response in a production scenario involving 11 production wells and six water-injection wells penetrating the reservoir's three compartments. Seismic surveys were simulated with isotropic elastic-wave modeling before the start of production and after 27.5 months of production at a simulated rate of about 67,500 barrels per day, with about 32,500 barrels per day of water injection. Rock properties were updated by petrophysical models calibrated to turbidite systems in the Gulf of Mexico. Analysis of the model and simulations improves understanding of the complex interaction of fluid effects, pressure changes, and rock deformation. For example, compaction in the reservoir may cancel time-lapse fluid effects, and compaction or dilation in the surrounding shales may override the observed reservoir signal in the seismic bandwidth. Strain-induced velocity changes in the shales have a much larger effect on estimated time-lapse time shifts than do strain-induced changes in path lengths. Geomechanical effects impact the interpretation of 4D seismic difference attributes and require careful consideration. The integrated, full-physics SEAM approach used for this model provides a unique data set to explore these complex production effects and the value of 4D seismic surveys. The models and data, which also include simulations of time-lapse gravity and electromagnetic surveys, are publicly available through SEAM.
Amplitude volume technique attributes and multidimensional seismic interpretation

Published: August 2017

Seismic attribute applications and their visualization provide dynamic tools to the seismic interpreter for gaining more insight into data being analyzed. Often, workflows are developed to broaden the scope of the analysis spectrum and to help arrive at a more realistic model of the subsurface, be it in terms of understanding the tectonic evolution of a fault or a production block, the comprehension of the reservoir geobodies, or even the overall architecture of the geologic elements in the zones of interest. One such workflow entails the calculation of the root mean square values of the seismic amplitudes and phase rotation, using novel methods for their visualization for drawing meaningful conclusions. We elaborate on this workflow by suggesting better ways of covisualization of different data volumes and putting them through multidimensional seismic interpretation. Through different examples, we demonstrate the added value of this workflow and how it can result in arriving at logical conclusions in the poststack (full offset or partial) seismic domain.

The nature and dynamics of spermatogonial stem cells
Authors: de Rooij Dirk G.
Published: August 2017

Spermatogonial stem cells (SSCs) are crucial for maintaining spermatogenesis throughout life, and understanding how these cells function has important implications for understanding male infertility. Recently, various populations of cells harbouring stem cell-like properties have been identified in rodent seminiferous tubules, but deciphering how these cells might fuel spermatogenesis has been difficult, and various models to explain SSC dynamics have been put forward. This Review provides an overview of the organization and timing of spermatogenesis and then discusses these models in light of recent studies of SSC markers, heterogeneity and cell division dynamics, highlighting the evidence for and against each model.
Microtubule organization, dynamics and functions in differentiated cells
Authors: Muroyama Andrew , Lechler Terry
Published: August 2017

Over the past several decades, numerous studies have greatly expanded our knowledge about how microtubule organization and dynamics are controlled in cultured cells in vitro. However, our understanding of microtubule dynamics and functions in vivo, in differentiated cells and tissues, remains under-explored. Recent advances in generating genetic tools and imaging technologies to probe microtubules in situ, coupled with an increased interest in the functions of this cytoskeletal network in differentiated cells, are resulting in a renaissance. Here, we discuss the lessons learned from such approaches, which have revealed that, although some differentiated cells utilize conserved strategies to remodel microtubules, there is considerable diversity in the underlying molecular mechanisms of microtubule reorganization. This highlights a continued need to explore how differentiated cells regulate microtubule geometry in vivo.

Published: August 2017

Monitoring of the state of the environment in the waterway itself and in the entire catchment area is important for its sustainable development. Heavy metals are strong environmental pollutants and many of them are toxic, even at very low concentrations. In this study River Drina was chosen due to these unique characteristics: the great river with large auto purification ability but in pressure of anthropogenic activities including hydropower plants, border between countries. The aim of this research was to compare data from chemical analyses of Ni, Zn, Cu, Cr, Cd, As, Pb and Hg contents in water, suspended solids and sediment with its contents in native macrophytes, Myriophyllum spicatum, and Potamogeton pusillus, in reservoirs of hydropower plants Bajina Bašta and Zvornik, on river Drina in Republic of Serbia. Contents of heavy metals in water were low and belongs to water class I. Heavy metal concentrations exceeds the limit values for Ni (184 mg/kg), Zn (3233 mg/kg), Cd (0.0042 mg/kg), Cu (157 mg/kg) and As (109 mg/kg) in Zvornik reservoir in suspended solids and sediment and for Zn (1048 mg/kg), Cu (402 mg/kg) and Hg (2.24 mg/kg) in Bajina Bašta reservoir, in suspended solids. In all the examined cases heavy metal contents in macrophytes were significantly higher than in water and relationship with suspended solids and sediment depends to plant species and metal. For Ni, Cd and As accumulation was obseved only in Myriophyllum spicatum, for Cu and Pb in both types. The obtained results indicate the need for further monitoring of the concentration of heavy metals in macrophytes, as well as sediment and suspended solids, in order to indicate and assess the quality of the aquatic ecosystem.

The knowledge of genetic inter-relationship between characters is also of theoretical and practical interest because a genotypic correlation may drive genetic linkage or from developmental induced relationships between components that are only indirectly the consequences of gene action. Terminalia arjuna is a medium to large sized fast growing versatile tree popularly known as Arjun. It has immense economic potential in various industries viz., pharmaceutical, timber, paper, soap, tannin, dye, match, food, fodder and fuel. Thirty candidate plus trees (CPTs) of T. arjuna were selected as seed source from 30 different provinces of Uttar Pradesh for the study of correlation study morphological & biomass traits. After 12 months of growth under nursery condition, data were collected and analyze for association studies. Present study concludes that magnitudes of phenotypic correlation coefficients were lower compare to corresponding genotypic values. A strong positive and highly significant phenotypic correlation with collar diameter, bark content, fresh shoot weight, dry shoot weight, fresh root weight, dry root weight and total biomass of seedling were exhibited. Therefore, these characters may be given proper emphasis during selection and breeding program of Arjun tree species where the amount of leaf, bark and biomass production is of immense importance.

Aerial application of persistent, bioaccumulative organochlorine pesticide endosulfan on cashew plantations to protect it from mosquito bug has led to contamination of soil and water environments in several parts of South Canara region, India. Endosulfan and its toxic residues like endosulfan sulfate are posing several threats to non-target organisms including humans. Biotransformation of toxic compounds using indigenous microbial strains is considered as safe and cost effective technique in bioremediation. In the present work, the bacterial strain designated as ES-1, has been isolated from the soil by enrichment method. The bacterial strain was found to mineralize endosulfan ˃99% of 100 mg/l completely biotically after 14 days of incubation by forming unknown polar metabolites.Whereas, abiotic degradation resulted in formation of a toxic compound, endosulfan sulfate. Based on 16s rDNA sequence analysis, the strain ES-1 showed 99% similarity to Bacillus sp. The results from the work suggest that, this bacterial strain could be employed for remediation of endosulfan contaminated environments.

Groundwater is the largest fresh water resource and radon is a radioactive naturally occurring noble gas that may be found anywhere in soil, air and water due to decay of uranium in rocks. It is important to investigate the radon in groundwater to safeguard against the health hazard caused due radon. The results presented here are from radon concentrations measured using RAD7 detector in 9 representative groundwater samples collected from hand pumps from southern parts of Roorkee in Haridwar district of Uttrakhand. Radon activity concentration was found in the range of 0.55+0.22 Bq L-1 to 3.39+0.28 Bq L-1 with an average value of 2.16+0.37 Bq L-1. Radon values were compared with United State Environmental Protection Agency value of 11 Bq L-1. The radon activity trend was found within the permissible limit.

The present study was carried out to assess the dust interception efficiency and impact of dust deposition on biochemical parameters of plant species growing alongside National Highway (NH-7) at Sirmaur, H.P, India. Plants are universal sink of CO2. The plant species selected for the study were Ficus roxburghii, Mallotus philippensis, Shorea robusta, Woodfordia fruticosa. The observed trend of dust accumulation was in the order Ficus roxburghii (38.30 mg m-2) > Shorea robusta (26.94 mg m-2),> Mallotus philippensis (22.31 mg m-2) > Woodfordia fruticosa (16.70 mg m-2). The present study revealed, that the leaf dust accumulation decreased with increasing distance from the national highway. Leaf dust accumulation was influenced by the seasons of the year with the maximum (30.70) in pre-monsoon and the minimum(21.42) in post-monsoon season.

The present investigations entitled “Inventorization of Water Resources in Solan Block of Himachal Pradesh” was conducted during 2012-13, with the objective to prepare a detailed inventory of water resources in the area, some latest had also been added. For inventory, a survey was conducted as per prestructured proforma. People’s perception was also recorded to verify the inventorization. In Solan Block the total number of water resources recorded in the field were 3218. Out of which 3070 number of water resources are being commercially exploited for use. A total of 412 hand pumps were installed in the area till December 2016. Out of the total water resources in Solan District, 22% ground and 30% surface water resources were in Solan Block. The people’s perception indicated that out of 35 panchayats, seven panchayats had water deficiency. In Solan Block 5.29 sq. km of total area was covered under 18 major irrigation schemes till 2016. A total population of 70,643 in rural area of Solan Block had a water requirement of 13,06,189.07 gallons per day whereas, that of urban population (45,845) was 15,13,801.9 gallons per day. The total water requirement of Solan Block calculated was 28,19,990.97 gallons per day for a population of 1,16,488 (Census 2011). The total water storage capacity in Solan Block on an average was 63,07,388.64 gallons to meet the demand of inhabitants along with water requirement for other purposes. But many times this capacity remained unutilized due to less water availability. Periodic water resource management is thus recommended for sustaining quality water availability.

Abstract. A field experiment was conducted to investigate the response of maize silage ( L.) to tillage depth under different soil firmness levels. The study was carried out on a 16 ha center-pivot irrigated field in a commercial farm located in the eastern region of Saudi Arabia. A soil firmness map was generated and used as a management map. This map was divided into three soil firmness zones based on soil cone index (low: 617 to 1270 kPa for a 0 to 15 cm depth in undisturbed soil, medium: 1271 to 1652 kPa and high: 1653 to 2306 kPa). Three tillage depth treatments (10, 20, and 25 cm) were imposed on each of the three soil firmness zones, using a tandem disc harrow. Maize growth parameters [plant population, plant height, and Normalized Difference Vegetation Index (NDVI)] and maize silage yield were used to evaluate the response of the maize crop to tillage depth. The results revealed that soil firmness and tillage depth at both early (25 days after sowing) and late (60 days after sowing) growth stages did not introduce significant effects on maize plant population. However, the plant height measured at 60 days after sowing showed a significant response to soil firmness. The lowest mean value of plant height (114.4 cm) was recorded at the high soil firmness level, while the greatest mean value (136.3 cm) was recorded under low soil firmness level. Also, significant differences in maize silage yield were recorded under different soil firmness levels and tillage depths. For maize silage production, a tillage depth of 10 cm was observed to be optimum for areas of low and medium soil firmness. For areas of high soil firmness, the optimum tillage depth was 20 cm.
