Modelling & Simulation of Fluid Flow Behaviour During Carbondioxide Sequestration in Coal Structure Using Comsol Multiphysics

In the present world, Global Warming has been one of the biggest problems regarding environmental aspect and CO2 is held responsible for that. It is an inevitable necessity to mitigate the concentration of CO2 in the atmosphere. CO2 sequestration is one of the best methods to reduce its concentration by trapping it beneath the earth in different geological conditions. The unmined coal seams and thin bands of coal provide a potential storage for CO2 with suitable geological environment. These days it has become necessary to study the relationship between coal structure and flow of fluids inside. In this project, an effort has been made to study the behaviour of fluids i.e. carbon dioxide and methane inside of coal and the analysis has been carried out to study their velocity and pressure variations using COMSOL Multiphysics. Coal contains both cleat and porous structure. Cleats are the natural fractures in coal and pores are the important factors for migration of fluid inside coal. Two separate models are developed to understand the fluid flow behaviour in both cleat and porous structure of coal. A study on 3D model has also been carried out by developing a uniform coal block to analyze pressure and velocity variations inside it

OF THE 11th PYTHON IN SCIENCE CONF

! We use a combination of code-generation, code lowering, and just-in-time compilation techniques called SEJITS (Selective Embedded JIT Specialization) to generate highly performant parallel code for Bag of Little Bootstraps (BLB), a statistical sampling algorithm that solves the same class of problems as general bootstrapping, but which parallelizes better. We do this by embedding a very small domain-specific language into Python for describing instances of the problem and using expert-created code generation strategies to generate code at runtime for a parallel multicore platform. The resulting code can sample gigabyte datasets with performance comparable to hand-tuned parallel code, achieving near-linear strong scaling on a 32-core CPU, yet the Python expression of a BLB problem instance remains source-and performance-portable across platforms. This work represents another case study in a growing list of algorithms we have "packaged" using SEJITS in order to make high-performance implementations of the algorithms available to Python programmers across diverse platforms

Evaluation of wound healing effect of colostrum and curcumin cream in rat excision wound model

Background: Proper wound healing is very crucial for the reconstruction of injured tissues. Compared to the conventional dressings, currently there are many novel biological wound dressings and healing agents containing colostrum which has many advantages. Aim & Objective: This experimental study was done to evaluate the effect of colostrum and curcumin cream dressing and compare it with that of conventional Povidone iodine dressing. Methods: The rats were anesthetized and excision wounds were created. Wounds were then measured with a standard measuring scale on the day of wounding and then subsequently at a time interval of 4 days till day 20, then on alternate days. After tracing the wound area was treated with the Test and Standard drugs on Day 1,4,8,12,16 and 20. The data was then analysed using Chi square, one-way ANOVA and two tailed t test using Graph pad prism software version 5.0. Results: Efficacy of Colostrum 10% &Curcumin 1% cream (test) was equal to that of povidone iodine 10% (standard) cream with respect to wound contraction and wound healing. But, with respect to the rate of wound healing, Colostrum 10% & Curcumin 1% cream treated group was better compared to the povidone iodine 10% cream treated group. Conclusion: Colostrum plus Curcumin cream has shown a better wound healing at a short time span in excisional wound model in rats, when compared to the conventional povidone iodine cream. Thus, the Colostrum plus curcumin cream appear to be an economical and safe alternative to costly therapies like growth factors for wound healin

Membrane Guided Regeneration in Periodontal Tissues

Periodontal regeneration is the restoration of lost periodontium or supporting tissues and includes the formation of new alveolar bone, new cementum and new periodontal ligament. The concept of GTR is based on the exclusion of gingival connective tissue cells and prevention of epithelial down growth into the wound, thereby allowing cells with regenerative potential (PDL and bone cells) to enter the wound first. GTR consists of placing barriers of different types to cover the bone and periodontal ligament thus temporarily separating them from gingival epithelium. Excluding the epithelium and gingival connective tissue from the root surface during the post-surgical healing phase not only prevent epithelial migration into the wound but also favors repopulation of the area by cells from the periodontal ligament and bone. Purpose and Scope -This review discusses the rationale for using guided tissue regeneration therapy. The review not only attempts to clarify the concept of selective tissue regeneration using non-resorbable and resorbable barriers, but to discuss differences in healing events after treatment with the two types of barriers together with their significance in periodontal therapy. At present, barrier membranes have potential clinical use in promoting periodontal tissue regeneration if patients to be so treated are selected appropriately. Research is still necessary to determine the critical period for guiding the ingrowth of new attachment forming cells and also to further clarify the concept of GTR involving the "wrong cell type" which inhibits periodontal tissue regeneration

Preventing postoperative swelling after periodontal surgery

Postoperative swelling following different surgical strategies is an area of great interest. The main part of the literature on the topic deals with swelling after periodontal surgery. In this review, we take into account different surgical strategies used including various flaps, no traumatic osteotomy, and primary or secondary closure. The use of pharmacological therapy and application of an ice pack is critical in the postoperative period and has always provided positive results. However, even if it is difficult to come to definite conclusions, due to the variability of the design of studies analyzed, the postoperative discomfort identified with edema, pain and trismus following wisdom tooth removal is influenced by various factors such as the difficulty of the surgical procedure involved, age and gender of the patient, and experience of the surgeon. The pharmacological therapy when performed with corticosteroids seems to improve control of the postoperative swelling related to this kind of surgeries

Wideband leaky‐wave antenna with dumbbell‐shaped slots on substrate integrated waveguides with twisted corrugations

Abstract This letter presents a new thin substrate‐integrated waveguide with twisted integrated–digitated capacitor‐based corrugations that offers a transmission loss 13 dBi throughout the frequency band. It has a frequency‐dependent beam‐scanning capability of 6 deg/GHz. The proposed antenna being thin is extremely conformal and is suitable for applications in millimetre‐wave off‐body communication
