Statistical approximation properties of Stancu type qq-Baskakov-Kantorovich operators

In the present paper, we consider Stancu type generalization of Baskakov-Kantorovich operators based on the q-integers and obtain statistical and weighted statistical approximation properties of these operators. Rates of statistical convergence by means of the modulus of continuity and the Lipschitz type function are also established for said operators. Finally, we construct a bivariate generalization of the operator and also obtain the statistical approximation properties.Comment: 16. arXiv admin note: substantial text overlap with arXiv:1508.0586

Present energy scenario and solar energy as an alternative option for environmental protection

In today’s scenario utilization of energy in an effective manner is must and that is the need of the time. After industrial revolution we are using the classical energy sources which are dependent on fossil fuels. The rate of exploration ofthese resources are much higher along with the higher rate of pollution. With the advancement in technology more efficient alternative energy sources have been recognized for environmental protection and are now available for various applications. This paper focuses one of the alternativeused for energy generation i.e. the solar option. In this study comparison of flat plate solar collector and evacuated tube solar collector is carried out and feasibility is reported

Pediatric urolithiasis: What role does metabolic evaluation has to play?

Background Pediatric urolithiasis is a perplexing problem faced by pediatricians as well as urologists across the globe. By early diagnosis and treatment of these risk factors, future stone formation may be prevented. Aim: To evaluate the clinical, biochemical and metabolic characteristics of the patients and the interventions required to prevent recurrence.Methods: In this retrospective study, cohort of pediatric patients presenting with urolithiasis at Kasturba Medical College, Manipal formed the study population. Patient’s records served as study tools. Medical records department was approached and data was collected. Metabolic evaluation was done in all children. Urine tests included urinalysis, urine culture, 24 hours urinary pH, volume, calcium, oxalate, citrate, uric acid, and creatinine. Finally a total of 58 pediatric urolithiasis cases were included in this study.Results: Mean age of study subjects was 6.85±1.27 years. Top three presentations of pediatric urolithiasis were symptoms of Urinary tract infection (UTI), abdominal pain and flank pain in 29.3%, 24.1% and 17.2% children respectively. Gross hematuria was observed in 15.5% of cases. 82.6% of stones were renal stones. Calcium oxalate stone was most common (50%) variety found. Hyperoxaluria was the most common (79.3%) metabolic abnormality detected. 31% had stone recurrence during follow up and 8 of these had >1 metabolic abnormality. Only 6/28 (21.4%) patients managed conservatively had stone recurrence whereas 12/30 (40%) managed with a procedure had stone recurrence.Conclusions: Metabolic evaluation for urolithiasis helps us to identify children those at increased risk for recurrent stone disease. Thus metabolic evaluation is a must in all pediatric patients as it helps in segregating patients needing medical therapy.

Comparative study between bone patellar tendon bone and quadrupled hamstring autografts in arthroscopic anterior cruciate ligament reconstruction with aperture fixation

Background: Bone patellar tendon bone (BPTB) and hamstring (HT) auto grafts have been used routinely in reconstruction of ACL over past two decades. Controversy still remains as to which graft is superior over other. Many studies have compared these graft options using different implants and different methods of fixation. Continuation of efforts in the same direction; purpose of the study is to compare these two graft options utilizing identical implants and similar method of fixation.Methods: 40 patients of clinically and radiologically diagnosed ACL tear fulfilling the inclusion and exclusion criteria were randomized into two groups to undergo arthroscopic ACL reconstruction using quadrupled hamstring graft (n=20) and bone patellar tendon bone auto graft (n=20) utilizing bioscrew by aperture fixation method in both the groups. They were compared post operatively for symptomatic improvement, clinical and rolimeter laxity tests and Lysholm functional knee scoring at 02 year.Results: At the end of 02 years laxity measurement by rolimeter showed slightly better results in BPTB group; however it was not statistically significant (p value= 0.362). Knee pain at the end of 02 year was slightly more in HT groups (45%) as compared to BPTB group (35%) but not significant (p value =0.748). Instability symptoms are comparable in both the groups (sense of giving away on exertion). Manual laxity testing by Lachman and Pivot shift tests were comparable in both the groups with p value of 0.695 and 0.999 respectively. Lysholm functional knee score also showed no statistical significance (p value =0.957).Conclusions: There is no significant difference between HT and BPTB auto grafts in terms of clinical and functional outcome at the end of 02 years.

Experimental and probabilistic model validation of ultrasonic MEMS transceiver for blood glucose sensing

In contrast to traditional laboratory glucose monitoring, recent developments have focused on blood glucose self-monitoring and providing patients with a self-monitoring device. This paper proposes a system based on ultrasound principles for quantifying glucose levels in blood by conducting an in-vitro experiment with goat blood before human blood. The ultrasonic transceiver is powered by a frequency generator that operates at 40 kHz and 1.6 V, and variations in glucose level affect the ultrasonic transceiver readings. The RVM probabilistic model is used to determine the variation in glucose levels in a blood sample. Blood glucose levels are measured simultaneously using a commercial glucose metre for confirmation. The experimental data values proposed are highly correlated with commercial glucose metre readings. The proposed ultrasonic MEMS-based blood glucometer measures a glucose level of 257±21 mg/dl. In the near future, the miniature version of the experimental model may be useful to human society

Treatment with clobetasol propionate 0.025% topical therapy in various dermatoses

Owing to their anti-inflammatory and vasoconstrictive properties. Topical corticosteroids (TCs) provide benefits in various dermatological conditions, including atopic eczema, psoriasis, chronic hand eczema, and localized vitiligo. Clobetasol propionate (CP) is the most common topical agent possessing anti-inflammatory, antimitotic, antipruritic, and immunosuppressive properties that are employed in the management of plaque psoriasis. CP 0.025% cream was approved by the United States food and drug administration for the treatment of moderate-to-severe psoriasis in adult patients. The formulation is free from known contact allergens, such as propylene glycol, short-chain alcohols, and sorbitol-based emulsifiers, and has demonstrated hypoallergenic effects. High penetration of active ingredients and a lower degree of systemic absorption make CP 0.025% an effective and safe agent. This case series discusses the clinical experience of using CP 0.025% cream in various dermatologic conditions, focusing on its efficacy and safety

Application of virtual reality, augmented reality, and mixed reality in endourology and urolithiasis: An update by YAU endourology and Urolithiasis Working Group

The integration of virtual reality (VR), augmented reality (AR), and mixed reality (MR) in urological practices and medical education has led to modern training systems that are cost-effective and with an increased expectation toward surgical performance and outcomes. VR aids the user in interacting with the virtual environment realistically by providing a three-dimensional (3D) view of the structures inside the body with high-level precision. AR enhances the real environment around users by integrating experience with virtual information over physical models and objects, which in turn has improved understanding of physiological mechanisms and anatomical structures. MR is an immersive technology that provides virtual content to interact with real elements. The field of urolithiasis has adapted the technological advancements, newer instruments, and methods to perform endourologic treatment procedures. This mini-review discusses the applications of Virtual Reality, Augmented Reality, and Mixed Reality in endourology and urolithiasis.publishedVersio

Structural, morphological, optical and electrical characterization of gahnite ferroan nano composite derived from fly ash silica and ZnO Mixture

The synthesis of a high value-added product, gahnite ferroan nano composite, from a mixture of fly ash silica and ZnO is a low-cost and non-expensive technique. The XRD pattern clearly reveals the synthesized product from fly ash after leaching is a product of high-purity gahnite ferroan composite. The grains are mostly cubical in shape. The optical band gap of powdered gahnite ferroan nano composite is 3.37 eV, which acts as a UV protector. However, the bulk sample shows that the 500 to 700 nm wavelength of visible light is absorbed, and UV light is allowed to pass through. So, the bulk sample acts as a band pass filter of UV light which can be used in many optical applications for conducting UV-irradiation activity. Dielectric permittivity and dielectric loss increase with a rise in temperature. The increase in the ac conductivity at higher temperatures denotes the negative temperature coefficient resistance (NTCR) behavior of the material
