Published: January 2022

Considering the negative consequences of the excessive use of non-renewable energy and the development of technologies related to photovoltaic energy, the present paper aims to analyze if the photovoltaic systems are economically viable for university hospitals. A photovoltaic system was designed in the parking lot of the University Hospital of the Federal University of São Carlos (UFSCar) and analyzed the financial viability of its installation. As a result, the photovoltaic system is financially viable, with an expected generation of 194.2 MWh in the first year and a payback of 7 years. Thus, this paper contributes to the feasibility of photovoltaic projects in university hospitals and the reduction of electric energy consumption, reducing its operational costs, reducing the emission of pollution, and diversification of the Brazilian energy matrix. Furthermore, the results can be used as a scientific basis for other fields, such as public and private hospitals and clinics.

Authors: Terra de Carvalho Wallace , Vendrametto Oduvaldo
Published: January 2022

A descoberta da bacia de Santos, em 2007, mostrou oportunidades do uso do gás natural obtido da exploração do petróleo do Pré-sal. Em 2011, a Petrobras iniciou estudos para expansão do gasoduto de transporte para aproveitar esta riqueza. A expansão da rede visava abastecer termelétricas, indústrias e demais consumidores. Promovendo a substituição pelo gás de fontes energéticas mais caras e poluentes, lenha, carvão e óleo combustível. Favorecendo assim a competitividade empresarial, o ambiente, a segurança de fornecimento e a redução dos custos de produção. Uma parte da expansão foi operacionalizada com resultados considerados satisfatórios conforme o plano energético nacional. Em 2019, a quebra do monopólio do gás da Petrobras, desinteressando-a a continuidade do negócio, abrindo espaço para entrantes.  A pesquisa que propiciou este artigo de caráter exploratório, tem forte apoio em documentos públicos e privados produzidos por instituições especializadas do setor. Consultas foram feitas a artigos e especialistas no assunto.

An Innovative Methodology of Confidence Level Assessment for Virtual Test of Ship Hydrodynamics
Authors: Zhao Feng , Wu Chengsheng , Shen Hongcui
Published: January 2022

An innovative methodology of confidence level assessment for virtual test of ship model hydrodynamics is presented in this paper. The methodology is based on the procedure of "uncertainty analysis, validation of optimal solution, validation by big sample data". In which the uncertainty analysis is based on orthogonal design and variance analysis methods and statistic inference theory, the validation of optimal solution is based on effect analysis in orthogonal design and principle of minimum deviation; the virtual test method is validated by statistical analysis of comparison with a large numbers of experimental data. The procedure is applied to practice with virtual test of ship model resistance, and shows that the methodology of confidence level assessment is reasonable and effective.
Experimental Study of Capsize Delay
Authors: Mizui Takashi , Latorre Robert
Published: January 2022

Roll-on Roll-off (Ro-Ro) ships can experience rapid capsize due to the loss of ship metacentric height from the free surface effect of vehicle deck flooding. To reduce the free surface effect it is useful to add subdivisions or partitions to the vehicle deck. This paper summarizes the results from a series of heel experiments where the heel angle is measured after a small volume of water added to a 1.8x0.47x0.31 m box model. The resulting heel angle was measured without partitions and with partitions up to 10 degrees. The observation of the water flow provides the basis for developing a mathematical model for capsize delay.
A Segmented Model Test of a Container Ship in Head Seas
Authors: Taravella Brandon M. , Marlantes Kyle E.
Published: January 2022

Dynamic global hull girder response is an important part of the structural design of a ship, especially one with significant length and bow flare. Experimental studies were conducted at the University of New Orleans’ towing tank where a segmented model of a containership was tested in head seas and zero speed. Bending strain at 3 locations along the model’s hull was measured. The results showed peak sagging bending moment that is approximately 25% larger than the peak hogging bending moment at midship. Minor differences were found between positive heave amplitude and negative heave peaks. The results of the experiment were also compared to an “in-house” non-linear quadratic strip theory computer program. The experimental results compared quite well with the numerical results. The results of the experiments and computer program indicate that the dynamic bending moment response is predominantly a second-order effect and linear predictions are not sufficient.
Flexibility of Seakeeping Simulation Tools for Landing Craft Hullforms
Authors: Silva Kevin , Silver Andrew , Weems Kenneth , Wundrow David , Zhang Sheguang
Published: January 2022

As the operational requirements of landing craft expand to faster speeds and higher sea states, more complex hullforms are being proposed to meet these requirements. The seakeeping performance of such vessels can become difficult to predict. Analytical tools must be flexible in order to handle the variety of operating conditions, hull geometries, loading conditions, and other attributes. The analytical seakeeping models should be based on the physical models of the hydrodynamic phenomena rather than case-specific empirical tuning. This paper describes a study that evaluated the ability of the Large Amplitude Motion Program (LAMP) to simulate traditional and non-traditional landing craft hullforms in varying operating conditions. The hullforms include a traditional semi-planing monohull, a semi-planing water jet propelled “W” shaped hull, a water jet propelled catamaran, and a catamaran Surface Effect Ship (SES) style hull. The measures taken to model each hullform and test conditions in LAMP are discussed and the correlation between experimental data and LAMP predictions are presented through comparisons of motions and accelerations.
Operational Experience With The New Harold E. Saunders Maneuvering And Seakeeping (MASK) Basin Directional Wavemaker
Authors: Hoyt John G. , Turner Steven R. , Moeller Herman J. , Carpenter Scott A. , Quintero Miguel R.
Published: January 2022

The Naval Surface Warfare Center, Carderock Division replaced their 21 pneumatic type wavemaker domes with a 216-paddle directional wavemaker in the fall of 2013. This wavemaker is capable of producing regular waves at oblique angles to the wave banks as well as long crested and short crested irregular model seas. Another powerful capability of the new system is the ability to preview the commanded waves in 3D virtual space on the computer screen. The new directional wavemaker facility has been in operation for four years. Mixtures of capabilities exceeding the original requirements as well as unforeseen problems were encountered. Based upon the operational experience gained in the last four years lessons learned are presented. Going from 21 domes to 216 individual paddles has adverse consequences on maintenance and reliability. That in and of itself is just a consequence of requiring a more complex machine to make more complex waves – not really good or bad. Despite the initial concerns this wavemaker has proven to be reliable, easily maintainable and when required, easily repairable.
Stochastic Inversion Framework to Monitor Evolving Mass Properties of a Ship at Sea during Arctic Operations
Authors: Lin Yolanda C. , Earls Christopher J.
Published: January 2022

This work investigates the indirect monitoring of Arctic ice accretion on ship surfaces using a stochastic inversion framework. An accurate assessment of a ship’s mass properties during operation is an important concern for ships traveling in adverse conditions. Specifically, in the Arctic, the risk of ice accumulation on the topside of the ship is heightened. Within such contexts, the actual, or current, first and second moment properties of the vessel, including accumulated topside icing, become critical in the associated equations of motion for a given ship. By leveraging an existing on-board inertial measurement unit in conjunction with existing seakeeping software, the framework here recovers a posterior distribution of a single mass property. The inverse problem is demonstrated with two mass properties: the vertical center of gravity (a first moment mass property), and the roll gyradius (a second moment mass property).

The inversion scheme requires two main inputs: an observed ground truth for the roll period, and an associated signal-to-noise ratio for the roll period measurement. The framework applies a Markov chain Monte Carlo (MCMC) inversion scheme, implemented in Python, that leverages Standard Ship Motion Program (SMP95) software in order to build a posterior distribution. Experimental model results from Research Vessel (R/V) Melville – Model 5748 provide the necessary inputs to the inversion scheme. Six different configurations, including one case of no icing and five cases of topside icing, are investigated within the context of this framework at full-scale from model-scale in order to invert for the six respective roll gyradii and vertical center of gravities. Icing configurations include both asymmetric and symmetric ice accumulation under moderate to heavy icing conditions.
A System to Measure Turbulent Lengthscales on Submerged Bodies of Revolution
Authors: Chesnakas Christopher J. , Cadel Daniel R.
Published: January 2022

A system has been developed to measure the turbulent lengthscales in the flow about a submerged body of revolution. The system consists of two Laser Doppler Velocimetry (LDV) probes mounted inside the body of revolution with the beams projected outside of the body through conformal windows. The measurement volumes of the two probes can be independently positioned within a plane perpendicular to the body axis. The probes are used to measure velocity time series at various spacings in the flow field. Auto- and cross-correlations are computed for each measurement pair, from which integral lengthscales are then found. Measurements are compared to canonical data from a turbulent free shear jet. In this paper, the system is described and its theory of operation detailed. Methods of computing the velocity correlations from the random-arrival-time LDV measurements are presented, and a new noise-removal scheme for non-uniformly sampled data is introduced. Six methods for calculating the integral lengthscale from autocorrelation data are reviewed, and the results discussed for the present jet data measured with LDV.
Upgrades to and Current Research Efforts Involving the Tow Tank Facility at the Naval Postgraduate School
Authors: Klamo Joseph T. , Jones Leo M. , Kwon Young W. , Didoszak Jarema M.
Published: January 2022

The Naval Postgraduate School has added wave making capability to the existing small tow tank that resides on campus. A new collaborative research effort between the Systems Engineering and Mechanical and Aerospace Engineering Departments is underway that utilizes this new capability. The aim of this new effort is to understand and predict the unsteady hydrodynamic loads experienced by a submerged vehicle operating near the surface. The tow tank was originally built around 1970 but only had the capability of testing models at slow speed in calm water. Even with this limited capability, a number of interesting studies were conducted in the facility including measuring the drag on a towed hydropower turbine and examining the forces due to collisions between floating ice equivalent objects and a composite plate. The new wave making capability in the tow tank is provided by a vertical plunging wedge that was modeled off of the sediment tank wavemaker at the United States Naval Academy. The wedge rides on a pair of vertical rails with the oscillation amplitude and frequency controlled by a linear actuator and electric motor. A variable angle wave absorbing beach is planned for the opposite end of the tank. An additional component of this modernization effort is the creation of a numeric tow tank, using ANSYS CFX, which can simulate the wave dynamics in the tank. This allows complementary numerical and experimental components of future research efforts. The current experimental effort involves characterizing the performance of the wavemaker and quantifying the wave environment throughout the tank. The wedge to wave amplitude transfer function has been determined over the relevant amplitude and frequency space. The uniformity of a wave crest has also been examined. For the numeric tow tank work, the wedge motion has been duplicated and the simulated wave elevation and propagation down the tank are being compared to experimentally measured results.
Low-Cost Image Processing Approach for Waterline Detection
Authors: Zuzick Aurore V. , Campana Jeff , Royce Richard
Published: January 2022

The height of the intersection between the free surface and a ship hull is of interest for many naval architecture applications. For example, wave height at a station influences the probability of water on deck, and wetted elevation at a buttock on a transom influences resistance forces. Determining this parameter through testing (either model- or full-scale) can be accomplished through various methods, many of which involve placing one or more measurement instruments in the flow field (e.g. resistance or capacitance probes or wires). However, the presence of these elements in the system can affect the flow itself. Non-invasive techniques, including sonic methods and laser-enabled technologies, avoid this issue, though there are benefits and drawbacks associated with these techniques as well. Measurement system complexity, in particular, can drive experimental cost and schedule. Some proven methods may provide more spatial resolution than is necessary to meet experimental objectives, providing extraneous information at additional cost. Image processing of digital camera video frames can be an effective non-invasive technique, though many commercially-available image processing tools are not designed specifically for this application. Though quite robust, these tools can add unnecessary time and cost to data processing for the waterline elevation problem. This paper lays out computationally-efficient image processing software methods which can be implemented in Matlab (without requiring additional toolboxes) to determine free surface elevation along a ship hull at a station or buttock using video files generated by cameras trained on the hull in the area of interest.
Innovative Experimental Investigation on the Influences of the Reynolds Number
Authors: Gu Jian , Fernandes Antonio Carlos
Published: January 2022

The influences of Re (Reynolds number) on the response of vortex induced vibration (VIV) have been studied by previous researches, which indicate the influences should not be ignored. However, due to the limitation of experimental facilities and complexity of the cases, the explicit influence of Re on VIV is still not fully known. Meanwhile, the industry standards also do not supply design reference taking account of Re effects quantitatively. In present work, an innovative dimensionless parameter (denoted as “inertia-viscosity”) is proposed to displace the Re in the dimensionless system, in order to clarify the individual effect of Re. With this method, comparing tests are concisely carried out, and the effectiveness and feasibility are demonstrated. Through the comparing of tests, several remarkable results are obtained.
“I Can’t Wait for You to Die”
Authors: Apple Harrison
Published: January 2022

Stemming from conflicts over the authority of professional archives to arrange and steward community knowledge, this article outlines the limitations of the archival apparatus to produce the conditions for social liberation through acquisition and offers suggestions for how to operate otherwise, as a collaborator in forgetting. It discusses the origins and revised mission of the Pittsburgh Queer History Project (PQHP) as a reflection of the precarious definition of community archives within the discipline and field of archival science. By retracing the steps in the PQHP’s mission, as it moved from being a custodial and exhibit-focused collecting project to acting as a decentralized mobile preservation service, I argue that community archival practice is an important standpoint from which to critically reassess the capacity of institutional archives to create a more conscious and complete history through broader collecting. Specifically, I demonstrate how contemporary attention to the value of community records and community archives is frequently accompanied by a demand for such archives, records, and communities to confess precarity and submit to institutional recordkeeping practices.

Published: January 2022

Data dimensionality informs us about data complexity and sets limit on the structure of successful signal processing pipelines. In this work we revisit and improve the manifold adaptive Farahmand-Szepesvári-Audibert (FSA) dimension estimator, making it one of the best nearest neighbor-based dimension estimators available. We compute the probability density function of local FSA estimates, if the local manifold density is uniform. Based on the probability density function, we propose to use the median of local estimates as a basic global measure of intrinsic dimensionality, and we demonstrate the advantages of this asymptotically unbiased estimator over the previously proposed statistics: the mode and the mean. Additionally, from the probability density function, we derive the maximum likelihood formula for global intrinsic dimensionality, if i.i.d. holds. We tackle edge and finite-sample effects with an exponential correction formula, calibrated on hypercube datasets. We compare the performance of the corrected median-FSA estimator with kNN estimators: maximum likelihood (Levina-Bickel), the 2NN and two implementations of DANCo (R and MATLAB). We show that corrected median-FSA estimator beats the maximum likelihood estimator and it is on equal footing with DANCo for standard synthetic benchmarks according to mean percentage error and error rate metrics. With the median-FSA algorithm, we reveal diverse changes in the neural dynamics while resting state and during epileptic seizures. We identify brain areas with lower-dimensional dynamics that are possible causal sources and candidates for being seizure onset zones.
Uvariopsis dicaprio (Annonaceae) a new tree species with notes on its pollination biology, and the Critically Endangered narrowly endemic plant species of the Ebo Forest, Cameroon
Authors: Gosline George , Cheek Martin , Onana Jean Michel , Ngansop Tchatchouang Eric , van der Burgt Xander M. , MacKinnon Lorna , Dagallier Léo-Paul M. J.
Published: January 2022

Background

The Ebo Forest area is a highly threatened centre of diversity in the Littoral Region of Cameroon, globally important for conservation with many threatened species including 68 threatened species of plant, yet not formally protected. The tropical African evergreen forest tree genus Uvariopsis Engl. & Diels (Annonaceae) is characterised by unisexual, usually cauliflorous flowers with a uniseriate corolla of four petals, and two sepals. Cameroon is the centre of diversity of the genus with 14 of the 19 known species.

Methods

The herbarium collection MacKinnon 51 from Ebo is hypothesized to represent a new species to science of Uvariopsis. This hypothesis is tested by the study of herbarium specimens from a number of herbaria known to hold important collections from Cameroon and surrounding countries.

Results

We test the hypothesis that MacKinnon 51 represents a new species to science, using the most recent dichotomous identification key, and comparing it morphologically with reference material of all known species of the genus. We make a detailed comparative morphological study focussing on three other Cameroonian species, Uvariopsis solheidii, U. korupensis and the sympatric U. submontana. In the context of a review of the pollination biology of Uvariopsis, we speculate that in a genus otherwise with species with dull, flesh-coloured (pink, red to brown) flowers pollinated (where known) by diptera, orthoptera and blattodea (flies, crickets and cockroaches), the glossy, pale yellow-green flowers of Uvariopsis dicaprio, with additional traits unique in the genus, may be pollinated by nocturnal moths. Based on MacKinnon 51, we formally name Uvariopsis dicaprio Cheek & Gosline (Annonaceae) as new to science, and we describe, and illustrate, and map it. Restricted so far to a single site in evergreen forest in the Ebo Forest, Littoral Region, Cameroon, Uvariopsis dicaprio is provisionally assessed as Critically Endangered using the IUCN, 2012 standard because the forest habitat of this species remains unprotected, and there exist imminent threats of logging and conversion to plantations.

Discussion

We show that the highest density of species of the genus (12), and of narrow endemics (5), is found in the Cross-Sanaga Interval of SE Nigeria and Western Cameroon. A revised key to the 14 Cameroonian species of Uvariopsis is presented. We review the other seven narrowly endemic and threatened species unique to the Ebo forest of Cameroon and discuss the phytogeographic affinities of the area.

Conclusions

Uvariopsis dicaprio adds to the growing list of species threatened with extinction at Ebo Forest due to current anthropogenic pressures.
Psychometric properties of the Valuing Questionnaire in a Spaniard sample and factorial equivalence with a Colombian sample
Authors: Ruiz Francisco J. , Odriozola-González Paula , Suárez-Falcón Juan C. , Segura-Vargas Miguel A.
Published: January 2022

Background

The Valuing Questionnaire (VQ) is considered as one of the most psychometrically robust instruments to measure valued living according to the acceptance and commitment therapy model. It consists of 10 items that are responded to on a 7-point Likert-type scale and has two factors: Progression and Obstruction. The Spanish version of the VQ showed good psychometric properties in Colombian samples. However, there is no evidence of the psychometric properties of the VQ in Spaniard samples. This study aims to analyze the validity of the VQ in a large Spaniard sample and analyze the measurement invariance with a similar Colombian sample.

Method

The VQ was administered to a Spaniard sample of 846 adult participants from general online population. Cronbach’s alpha and McDonald’s omega were computed to analyze the internal consistency of the VQ. The fit of the VQ’s two-factor model was tested through a confirmatory factor analysis with a robust maximum likelihood (MLR) estimation method. Afterward, we analyzed the measurement invariance across countries and gender. Convergent construct validity was analyzed with a package of questionnaires that evaluated experiential avoidance (Acceptance and Action Questionnaire-II, AAQ-II), emotional symptoms (Depression Anxiety and Stress Scale-21, DASS-21), life satisfaction (Satisfaction with Life Scale, SWLS), and cognitive fusion (Cognitive Fusion Questionnaire, CFQ).

Results

The internal consistency across samples was adequate (alphas and omegas were .85 for VQ-Progress and .84 for VQ-Obstruction). The two-factor model obtained a good fit to the data (RMSEA = 0.073, 90% CI [0.063, 0.083], CFI = 0.98, NNFI = 0.97, and SRMR = 0.053). The VQ showed strict invariance across countries and gender and showed theoretically coherent correlations with emotional symptoms, life satisfaction, experiential avoidance, and cognitive fusion. In conclusion, the Spanish version of the VQ demonstrated good psychometric properties in a large Spaniard sample.

Authors: Sajjanar Jayashree , Soni Minal , Gade Jaykumar , Agrawal Megha , Sajjanar Arunkumar Basavaraj
Published: January 2022

Introduction: Temporomandibular Disorders (TMDs) accounts for common Orofacial Pain (OFP) arising from musculoskeletal origins, affecting almost 80% of the overall population. The multifactorial nature of the disease makes it difficult to diagnose and treat and is challenging to a considerable number of General Dental Practitioners (GDPs). They’re increasingly approached by patients for advice on TMD, but little is understood about how this disorder is addressed with in primary health care. Aim: To assess the awareness and knowledge regarding management of TMDs among GDPs in Central India. Materials and Methods: The cross-sectional study was conducted at Central India, Nagpur, Maharashtra, India from 20th June 2020 to 12th December 2020, including 200 general dental practitioners, who were registered under the Dental Council of India. A questionnaire consisting of 17 questions with reference to TMDs was designed and the questionnaire was circulated through a web designed program. The responses were collected, and data were analysed descriptively using Statistical Package for the Social Sciences (SPSS) statistics for windows version 24.0. Results: The mean age of the participants in the study was 24.80±1.63 years. Predominantly, participants were 164 females (82%). Among all the participants, about 181 (90.50%) of GDP’s were practicing Dentistry. The study findings suggest that the overall general practicing dentists encounter TMD cases and 162 (81%) of GDP’s treat patient at their clinic. A 76% of GDPs acknowledged the causative factor for TMD to be multifactorial and physical examination (88.50%) as the diagnostic tool. Most of the general practitioners around 126 (63%) preferred referring the patient to the specialist, maxillofacial surgeon. Among the practitioners who were confident in treating TMD, occlusal splint was the treatment of choice for 198 (96%) of the GDPs. Conclusion: Many GDPs lack standard protocol knowledge, felt insecure in TMD diagnosis, therapy decisions and treatment. There is a requirement for better quality evidence on which TMD diagnosis and treatment, including the event of a valid, reproducible patient-centered outcome measure to enable dental practitioners to feel confident in managing TMD. It is essential to train GDPs to identify individuals with TMDs through professional courses and training. It would be highly beneficial to educate the undergraduates regarding the diagnosis of TMDs in their curriculum.
Does Dual Motor Tasks Provokes Posture Adaptations in Healthy Young Adults? A Cross-sectional Study
Authors: Bowman Carley , Jose Aleena , Rosario Martin G
Published: January 2022

Introduction: Most studies on postural deviations during single and dual tasks have been extensively studied in neuromuscular and older adult populations. Nevertheless, further research is warranted to identify whether such tasks can impose postural adaptations in young, healthy adults without sensory impairments. Aim: To assess postural stability modifications in young adults during single tasks and dual motor tasks (holding a cup filled with water) while concomitantly challenging the sensory systems. Materials and Methods: This was the cross-sectional study on 82 young adults (18-45 years old) from Texas Woman’s University (TWU) Health Science Center in Dallas, Texas, and surrounding areas. Standing postural control was measured by collecting total sway, direction of sway and velocity in the Anterior-Posterior (AP) and Medial-Lateral (ML) directions during different balance tasks. For single and dual tasks, the tests were performed with a bipedal stance on foam involving challenging the sensory input via Eyes Open (EO), Eyes Closed (EC), and head movements with eyes open (EO HUD) and closed (EC HUD). The dual motor tasks were similar to the single tasks with the addition of holding a cup full of water to split attention. Data were placed into the Statistical Package for Social Sciences (SPSS) Data Analysis 25.0 system and were analysed for repeated measures Analysis of Variance (ANOVA) analysis. Results: Eighty-two healthy young adults participated in this study (mean age of 24.6±2.7 years, 13 males and 69 females). An ANOVA analysis revealed that postural stability was considerably altered during motor tasks. Sway in the Antero-Posterior (AP) direction, and velocity of sway increased as the complexity of the tasks intensified. A substantial difference in total sway during single tasks when eyes were closed compared to eyes open (p-value <0.01) was noted. There was a significant difference in total sway (AP and ML) during eyes open (EOM) to eyes closed (ECM) and during eyes open with head moving up and down (EOM HUD) (p-value 0.001). There were significant differences in mean AP velocity during EO (0.11±0.12) compared to EC HUD (0.19±0.15), and when comparing EOM (0.07±0.04) to ECM HUD (0.13±0.08) (p=0.01) Conclusion: This study identified postural changes when comparing single and dual tasks in healthy young adults, and the outcomes of this study showed definite distinctions in postural responses during single and dual motor tasks.

Published: January 2022

Introduction: Adequate knowledge of the anatomic variation and root canal morphology is paramount for long term endodontic success. The presence of two canals in Mesiobuccal (MB) root is commonly associated with maxillary molars in various populations. Aim: To retrospectively evaluate the prevalence of a second mesiobuccal canal (MB2) in maxillary first and second molars in Delhi-National Capital Region (NCR) population using Cone Beam Computed Tomography (CBCT) analysis. Materials and Methods: This retrospective study evaluated the records of complete maxillary CBCT scans of 204 maxillary first and second molars from January 2016 till May 2019 from different CBCT centres in Delhi-NCR region to determine the anatomy and morphology in June 2019. The prevalence of second MB2 canals was recorded and associated with age, gender and symmetry. The z-test for proportions was used to assess the differences among the subgroups. Results: The number of roots in 204 teeth in both maxillary molars were determined. The prevalence of 3-rooted configuration was 98.55% in maxillary first molars and 79.4% in maxillary 2nd molars. Also, in maxillary 2nd molars, 7.4% were single rooted and 13.2% had 2-rooted configuration. Three rooted configuration and variable canal number was commonly reported in maxillary molars. Prevalence of MB2 canal was 87.2% in maxillary 1st molars and 64.2% in maxillary 2nd molars. Also, the prevalence was 87.2% bilaterally in maxillary first molars and 65.7% on the right and 53.9% on the left in maxillary second molars respectively. Type IV canal configuration was most prevalent in 44.60% of maxillary first molars and type 1 configuration (35.78%) for the maxillary second molars. Conclusion: Prevalence of MB2 canals in maxillary first and second molars was found to be high in North Indian population and the clinician should suspect its presence in all cases. Prevalence of MB2 had bilaterally symmetrical distribution without any association with age or gender. The MB roots were more likely to exhibit type IV and type II canal configurations in maxillary first molars and type I and type II configurations in second molars.

Published: January 2022

Introduction: Cryotherapy has been a widely used thermotherapy modality in sports injuries. The main focus of research on cryotherapy was to find out its effects on functional performance measures of the players. Cryotherapy is known to dampen the stretch reflex and reduce muscle temperature which might indirectly influence the flexibility and power which are the important components of any performance. Hence, it becomes necessary to study the changes, if any, on the flexibility and power post cryotherapy application. Aim: To determine the effects of cryotherapy on lower limb flexibility and power in adult recreational players. Materials and Methods: The present study was an experimental study conducted on 40 recreational players of either gender, between the age range of 18-25 years, who played various forms of recreational sports and had hamstrings and calf muscle tightness were included in the study. Hamstring tightness was assessed by Active Knee Extension Test (AKET) and calf muscle tightness by Weight Bearing Lunge test (WBLT), while power was assessed by vertical jump test. Both the limbs were given cold pack on bilateral calf and hamstrings for 20 minutes for three days. Outcomes were measured on 3rd day and paired t-test was used to analyse the pre and post-treatment difference, p-value less than 0.05 was considered as significant. Results: A total of 40 recreational players were included in the study with the mean age of 22.15±1.36 years, of which 20 were males and 20 were females with mean Body Mass Index (BMI) of 23.07±3.36 kg/m2. The right calf muscle flex (pretreatment=13.7 cm to post-treatment=14.71 cm, p<0.05) along with left side flexibility (pretreatment=14.2 cm to post-treatment=15.07 cm, p<0.05). The hamstring flexibility improved significantly from mean, pretreatment=45.6 degrees to post-treatment=50.6 degrees (p<0.05) on the right side while on the left side, a non significant improvement from pretreatment=52.38 degrees to post- treatment=55.22 degrees (p=0.011) was seen. The power showed a non significant reduction from pretreatment=17.61 to post- treatment=16.76 (p=0.016). Conclusion: Cryotherapy increases the flexibility of calf and hamstring muscles and reduces lower limb power after three days of cryotherapy application.

Studies were carried out at Agricultural Research Station, Seethampeta in Andhra Pradesh during the kharif season for three consecutive years starting from 2017 to 2019 on the population dynamics of insect pests occurring in paddy and also to assess the influence of weather parameters on insect pests. The insect pests observed in the light trap catches were, Yellow stem borer, Gall midge, Leaf folder, Green leafhopper, Plant hopper (BPH/WBPH) and Grasshoppers. The light trap catches of rice insect pests were recorded at weekly interval during 32nd Standard Meteorological Week (SMW) to 52nd Standard Meteorological Week (SMW) and the data were correlated with the weather parameters. The results revealed that more number of adults of Yellow stem borer were noticed during the year 2019 from 45th to 48th SMW and the correlation studies revealed that that maximum temperature, minimum and maximum relative humidities had significant positive influence and regression value of R2 (743, 638 and 726 during 2017, 2018 & 2019). The population of gall midge was negligible during the year 2017 and 2018. Whereas, in 2019 peak was notice during 38th SMW (15 No’s) maximum relative humidity has positive relation with increase in the gall midge population. Leaf folder adults were trapped more in the light traps during the year 2019 with peak catches of 11.00 No’s on 42nd SMW and were positively correlated with maximum temperature, minimum and maximum relative humidities. Similarly, leafhopper, brown leaf hopper, grass hoppers were positively correlated with the relative humidity.

Reservoir sedimentation is a regular process and sequential path of sedimentation in reservoirs comprising of erosion, entrainment, transference, deposition and compaction of dregs carried into artificial lakes formed behind the dams. India houses 5334 large dams in function (2329 numbers before 1980) and 411 dams are in pipeline. The Rengali dam, functioned from 1984, that traps 50% of the total sediment load of the Brahmani River continues to thwart the growth and buffering of the Brahmani delta.

Remote sensing (RS) and Geographical Information System (GIS) have emerged as powerful tools to create spatial inventory on Hydro-Bio-geo resources and the state of the environment. The RS/GIS and process-based modelling employed in spatial and dynamic assessment of loss in live storage of the reservoir by developing contour, aspect and slope map by using data received from LANDSAT sources.

The sedimentation of the Rengali reservoir (functional from 1984) studied for three decades 1990-2000; 2000-2010 and 2010- 2020 by constructing contour, aspect and water spread area maps by using web based data (satellite downloads). The web based water spread area data analysed by GIS tool for integration, spatial analysis, and visual presentations.

The results revealed that the decadal rate of sedimentation of Rengali reservoir is reducing with age. An appropriate reservoir operation and management system as per defined protocols considering sediment related problems is essential for controlling the ageing processes that may diminish the safety and shorten the reservoir life.

A case of pseudopregnacy was presented to Veterinary Teaching Hospital, Michael Okpara University of Agriculture Umudike, Nigeria. Eighteen (18) months old bitch weighing 15kg was presentedclinical signs suspected to be pseudopregnacy, which was observed four weeks after the bitch came on heat (estrus). The clinical signs observed were restlessness, anorexia, aggression, nesting behaviour and licking of mammary gland. On clinical examination it was observed that bitch had enlarged mammary glands and milk secretion. The physiological parameters were found to be within the normal range.  Abdominal palpation, ultrasonography and vagina cytology were carried out to confirm pregnancy. Due to absence of foetuses on abdominal palpation and ultrasonography and presence of scanty epithelial cells in vaginal cytology, it was confirmed and concluded to be a case of pseudopregnancy. Causes, treatment and other associated factors with pseudopregnancy were further discussed.

Diabetes is a group of metabolic disorders with various etiologies that are defined by persistent hyperglycemia and worsening carbohydrate, lipid, and protein digestion due to flaws in insulin discharge and insulin activity. Indians account for one out of every five diabetics of the world. Around 35 million Indians suffer from diabetes, which affects around 150 million individuals worldwide. Because health is a major concern in people’s daily lives, foods that are healthy and beneficial to health are becoming increasingly popular. Natural food variations are widely used for the prevention and treatment of a variety of healthy issues. Supplements such as protein, iron, and calcium can be found in plenty of treats. The goal of this study was to develop solid treats using Gymnema sylvestre leaf powder, an Ayurvedic component with increased nutraceutical value. Multigrain powder, heating powder, palm sugar, cardamom powder, Margarine, salt, bubbling blend, and G.sylvestre leaf powder were among the ingredients used to make the solid snacks. The powder was created by drying the leaves in a plate dryer at 50°C for 2 hours before crushing in a home processor. G.sylvestre leaf powder was fused at different percentages: 0.25 percent, 0.50 percent, 0.75 percent, and 1.00 percent. Supplement testing, mineral analysis, and tactile testing are not set in stone. Atomic Absorption Spectroscopy was used to determine mineral composition. Over a variety of examples, test 0.50 percent sound snacks were found to be organoleptically superior.

Medulloblastomas are the most common primary malignant brain tumors in childhood. They are responsible for around 20–40% of all brain tumors in children. They rarely occur in adulthood, but here they only make up less than 1% of all brain tumors. The standard therapy consists of an operation in combination with radiation and chemotherapy, which are individually determined for the patient. In this article, we discuss a case of 47 years old female patient diagnosed with primary progressive multiple sclerosis since 1 year. After 3 months of the diagnosis, she deteriorated and became unable to walk. MRI showed a large patchy enhancing midline cerebellar mass with evolving hydrocephalus. Tumor expressed positive reaction with synaptophysin immunohistochemical stain rendering medulloblastoma diagnosis.

There is currently no specific evidence regarding the exact etiology of anal fissures. However, various management options were reported and validated among the relevant research. Lateral internal sphincterotomy has been validated among relevant investigations in the literature as a valid modality for managing patients with chronic anal fissures. In the present literature review, we formulated evidence based on these studies to compare open and closed techniques of this surgery according to the reported outcomes. However, evidence regarding the superiority of either of the techniques over the other is not consistent among these investigations. For instance, some studies reported that closed sphincterotomy is more favorable than the open approach and should be considered the treatment choice for chronic anal fissures. This is because the technique is associated with less frequent rates of complications, less expensive, safe, and effective. On the other hand, many other relevant studies also demonstrated that the reported outcomes for the two modalities exhibited non-significant differences. Therefore, we suggest that researchers should furtherly conduct additional investigations before drawing any conclusions in this field.
