Hemisection- A Saviour for Periodontally & Cariously Involved Permanent Mandibular Molar

Progressive carious and inflammatory involvement of teeth if left untreated will ultimately lead the loss of tooth structure in the oral cavity. Earlier clinician was left with no option but extraction of such hopeless teeth followed by replacement with fixed partial denture, removable partial denture or implants. Hemisection is a removal of compromised root and the associated crown portion. It is one of the treatment options for preserving remaining part of molar having sound periodontium. This case report presents a patient in which distal half of the teeth was carious but with sound periodontium and the periodontally compromised mesial root was resected, and after healing, fixed dental prosthesis was delivered to restore proper form and function

The Political Ecology of Death: Chinese Religion and The Affective Tensions of Secularised Burial Rituals in Singapore

This paper explores the political ecology of death and the affective tensions of secularised burial rituals in Singapore. Although scholars have recently acknowledged the roles of biopower and affect in shaping environmental politics, religion and death as socio-affective forces have not been substantively engaged with by political ecologists. We argue that death is inherently both a spiritual and ecological phenomenon, as it exposes not only the spiritual geographies that structure how people see the natural world, but also the affective tensions and struggles over what counts as a “proper” form of burial in relation to religion and nature. First, we demonstrate how the Singapore state utilises a politico-ecological discourse to secularise Chinese death rituals, such that the death can be separated from the transcendent spheres and incorporated into the environmental biopolitics. Second, we focus on how people's variegated affective inhabitations of religion and secularity condition the political ecology of death. In doing so, this paper foregrounds the roles of religion, secularity and affect in rethinking the “political” of political ecology.

Borderline Gardening

Based on ethnographic fieldwork among Chinese nationals working in Mongolia, this research note explores various forms of gardening that unfolded as side-projects at sites where Chinese enterprises were engaged in the extraction of oil, zinc and fluorspar. At first, the organisation and activities of these Chinese operations appeared to stem from a penchant for walled compounds and gardening. However, on closer inspection, the horticultural enclaves were not really a unilateral imposition of a culturally determined aesthetics, but rather the outcome of a negotiation, informed by prevailing ethnic stereotypes, of the proper form a Chinese presence could assume in Mongolia.

Rasayana karma of poisonous Bhallataka: A Review

Rasayan is a branch of the Ayurveda. Charaka had described fulfilling the aim of the Ayurveda i.e., drugs act by preventing old age and diseases in the healthy person. Charaka stated about two types of medicine, one which promotes resistance to the body and another which cures diseases and Rasayan therapy play a key role in achieving these goals The main aim of Rasayan therapy is to promote the formation of or resistance which in modern terminology can be called as promoting the strength of the immune system. Bhallataka, a medicinal drug has the ability to penetrate deeply into the tissues and rejuvenate the body that’s why it was used to hold in high esteem by ancient sages of Ayurveda. Maharshi Charak emphasized the Rasayana property of Bhallataka and described ten types of preparations with it. He considered bhallataka as the best drug to cure the kaphaj vyadhi. Charak has categorized Bhallataka as Dipaniya -an appetizer, Bhedaniya- to break accumulated doshas, mutra sangrahaniya- antidiuretic, and Kusthaghna -antidermatosis. In the present study, review of the drugs had been made from Ayurveda classics. Because it is important to have an awareness regarding the Poisonous drugs, when used in the proper form & prescribed dose they act as a potent therapeutic agent. It is a fact that virtually any substance can be harmful at high enough concentrations as rightly quoted that “All substances are poisons; there is none which is not a poison. The right dose differentiates a poison from a remedy.”

Trapezoid and Midpoint Type Inequalities for Preinvex Functions via Quantum Calculus

In this article, we use quantum integrals to derive Hermite–Hadamard inequalities for preinvex functions and demonstrate their validity with mathematical examples. We use the qϰ2-quantum integral to show midpoint and trapezoidal inequalities for qϰ2-differentiable preinvex functions. Furthermore, we demonstrate with an example that the previously proved Hermite–Hadamard-type inequality for preinvex functions via qϰ1-quantum integral is not valid for preinvex functions, and we present its proper form. We use qϰ1-quantum integrals to show midpoint inequalities for qϰ1-differentiable preinvex functions. It is also demonstrated that by considering the limit q→1− and ηϰ2,ϰ1=−ηϰ1,ϰ2=ϰ2−ϰ1 in the newly derived results, the newly proved findings can be turned into certain known results.

FINISHING AND POLISHING OF DIRECT COMPOSITE RESTORATIONS - A REVIEW

Contemporary cosmetic dentists are expected to create realistic and seamless restorations that mimic natural tooth structures. Recent advancements in composite resin systems have improved the practitioners ability to deliver optimal results using chair-side techniques. Many times, the form and function is achieved but the surface of these restorations is not smooth. This might lead to rough or uneven surfaces which over time invite microbial flora leading to an inevitable failure of the restoration. To avoid such failures and to satisfy this patient-driven demand for aesthetic restorations, the use of exemplary finishing and polishing materials is required. These techniques of finishing and polishing helps to achieve the proper form and function of the restoration along with pleasing aesthetics and the maintenance of proper periodontal and gingival health. This article aims to briefly outline finishing and polishing of composite restorations.

High School Basketball Coach and Player Perspectives on Warm-Up Routines and Lower Extremity Injuries

Background While participation in sports-related activities results in improved health outcomes, high school athletes are at risk for lower extremity injuries, especially ankle, knee, and thigh injuries. Efforts to promote the adoption and implementation of evidence-driven approaches to reduce injury risk among school-aged athletes are needed. However, there is limited research regarding the perceived barriers, facilitators, and adherence factors that may influence the successful implementation of effective warm-up routines among this population. Methods We conducted a qualitative study using semi-structured interviews and focus groups to assess high school basketball coach and player current practices, knowledge, and perspectives about warm-ups and lower-extremity injuries (LEIs). We interviewed coaches (n = 12) and players (n = 30) from May to October 2019. Participants were recruited from public high schools in a joint school district in Southern California. Multiple coders employed thematic analysis of the data using validated methods. Results Coaches and players reported regular engagement (e.g., daily) in warm-up routines, but the time dedicated (range 5–45 min), types of exercises, and order varied substantially. Players often co-lead the warm-up practice with the coach or assistant coach. Despite regular engagement in warm-up, players and coaches report multiple challenges, including (1) limited time and space to warm-up effectively at games, (2) a perception that young players are not prone to injury, (3) competing demands for coaches’ time during practice, and (4) coaches’ lack of knowledge. Coaches and players perceive that warming up before practice will result in fewer injuries, and many players are motivated to warm up as a result of their personal injury experience; however, they desire guidance on the ideal exercises for preventing injury and training on the proper form for each exercise. Conclusions Regular involvement in basketball warm-up routines is common among high school teams, but the methods and time dedicated to these practices varied. Players and coaches are eager for more information on warm-up programs shown to reduce LEIs.

Software Engineering Techniques for the Extraction of Ontology of Historical Geographic Information

Unorganized processing textual information in large files is time consuming and error-prone, especially if the texts are ununiform. Investigating past and historical data concerning geography and economics can be facilitated a lot when the data is stored in a data base or has a proper form.

Data-Driven Inference of the Mechanics of Slip Along Glacier Beds Using Physics-Informed Neural Networks

<p>Reliable projections of sea level rise depend on accurate representations of how fast-flowing glaciers slip along their beds. Specifically, ice sheet models require a quantitative sliding law that relates basal drag to sliding velocity and glacier geometry, yet the proper form of the law remains uncertain. Here, we present a novel deep learning-based framework for learning the time evolution of basal drag from time-dependent ice surface velocity and elevation observations. We train a pair of probabilistic neural networks through a combination of time-dependent surface observations, governing equations for ice flow, and known physical constraints. Neural network outputs are stochastic predictions of time-varying basal drag that do not require any prior assumptions on the form of the sliding law. This training strategy is well-suited to large volumes of remote sensing data while providing a natural way to integrate our existing understanding of the physics of ice flow into the learning process.</p><p>We test this framework on 1D and 2D ice flow simulations and demonstrate that, under certain stress conditions, recovery of the underlying sliding law parameters and their uncertainties can be derived from the stochastic predictions of time-varying basal drag. We also apply these methods to Rutford Ice Stream and Pine Island Glacier in Antarctica to investigate subglacial hydrological effects for the former and evidence for regularized Coulomb sliding for the latter.</p>

Coupled vibrations of viscoelastic three-layer composite plates. 2. Numerical experiments

Results of numerical studies of the influence of reinforcement orientation of hard layers and the relative thickness of the soft layer of an isotropic viscoelastic polymer on the values of natural frequencies and coefficients of mechanical losses are discussed. In a symmetrical three-layer plate, a bending-torsion interaction arises, generating mutual transformations of the eigenmodes of the coupled vibration modes, if at least one of its own forms in plate directions is characterized by an even number quarters of a wave, and another proper form - an odd number of quarters the waves. In an unsymmetrical asymmetric three-layer plate, bending-bending interaction arises, generating mutual transformations eigenmodes of coupled vibration modes in two mutually orthogonal planes if in the main directions of the plate both of their own forms characterized by either an even or an odd number of quarters of a wave. It was found that each mode of natural vibrations of three-layer plates corresponds to the effective relative thickness of the soft isotropic layer viscoelastic polymer.
