Algorithm for object detection using raspberry pi

This paper presents about “Detecting the movement of object and capture the still of the object”. It describes how the system is built and implemented in the embedded device using “Raspberry Pi”. These type of system is troubled people for years because it is expensive, large size, hard to install and immovable after installed. To solve this problem, “An Object Detection Monitoring System can be designed using Raspberry Pi, PIR Sensor and Pi camera as hardware modules with help of python language and Linux shell script. The program can be developed using these languages to detect the motion of object and takes picture of it and send to mail under Internet network, same time it will record the video of motion. And It is capable of finding the ratio of detected object with in the camera frame

A study assessing the knowledge, attitude, and practice of materiovigilance among medical professionals in the states of Tamil Nadu and Andhra Pradesh, India

Background: Medical devices are vital for healthcare diagnosis and treatment but pose inherent risks. Physicians and healthcare professionals play a crucial role in reporting adverse events associated with these devices. Despite this, there is a notable scarcity of literature addressing the knowledge, attitudes, and practices surrounding India's Materiovigilance (Mv) Program. This study aimed to evaluate the knowledge, attitudes, and practices of doctors and postgraduate residents in Andhra Pradesh and Tamil Nadu regarding the Materiovigilance program of India (MvPI). Methods: It was conducted as an observational, cross-sectional study, a structured self-administered Google Form survey was distributed among medical professionals and citizens of Andhra Pradesh and Tamil Nadu. The survey, comprising 22 questions on knowledge, attitudes, and Mv practices, was disseminated via various social networking sites. Results: Out of 700 doctors and postgraduate residents surveyed, 496 responded, yielding a response rate of 70.8%. The majority (96.8%) acknowledged the potential for adverse events from medical devices, with 91.1% agreeing on healthcare professionals' responsibility to report such events. Despite experiencing medical device-related adverse events in practice (63.3% of respondents), only a small fraction (12.1%) reported them, although 93.5% expressed willingness to report. Conclusions: The study underscores a knowledge gap among physicians and residents regarding MvPI in India, highlighting the necessity for educational interventions. To address this gap, MvPI coordinators should organize conferences and seminars aimed at enhancing awareness and reporting practices among healthcare professionals

5 wave interactions in internal gravity waves

We use multiple-scale analysis to study a 5-wave system (5WS) composed of two different internal gravity wave triads. Each of these triads consists of a parent wave and two daughter waves, with one daughter wave common between the two triads. The parent waves are assumed to have the same frequency and wavevector norm co-existing in a region of constant background stratification. Such 5-wave systems may emerge in oceans, for example, via tide-topography interactions, generating multiple parent internal waves that overlap. Two 2D cases are considered: Case 1(2) has parent waves with the same horizontal (vertical) wavenumber but with different vertical (horizontal) wavenumber. For both cases, the 5WS is more unstable than triads for $f/\omega_1\gtrapprox0.3$, where $\omega_1$ and $f$ are the parent wave and the local Coriolis frequency, respectively. For $f/\omega_1\gtrapprox0.3$, the common daughter wave's frequency is $\approx \omega_1-f$ and $f$ respectively for Cases 1 and 2. For 3D cases, 5WSs become more unstable as the angle ($\theta$) between the horizontal wavevectors of the parent waves is decreased. Moreover, for any $\theta$, 5WSs have higher growth rates than triads for $f/\omega_1\gtrapprox0.3$. Numerical simulations match the theoretical growth rates of 5WSs for a wide range of latitudes, except when $f/\omega_1\approx0.5$ (critical latitude). More than three daughter waves are forced by the two parent waves when $f/\omega_1\approx0.5$. We formulate a reduced order model which shows that for any $\theta$, the maximum growth rate near the critical latitude is approximately twice the maximum growth rate of all triads

Formulation and Invitro Evaluation of Fast Dissolving Telmisartan Tablets Using Different Superdisintegrants

The concepts of formulating Fast Dissolving Tablets of Telmisartan offers a suitable an practical approach in serving desired objectives of faster disintegration and dissolution characteristics. In the present work, Fast dissolving tablets of Telmisartan were prepared by Direct Compression Technique using Crospovidone, Croscarmellose sodium Sodium starch glycolate as Super disintegrants. All the Fast dissolving tablets of Telmisartan prepared were subjected to Drug content Uniformity, weight vaiation, Hardness, Thickness, Friability, Disintegration and Dissolution studies. Pre Compression parameters like Bulk density, True density, Porosity Angle of repose. The result of angle of repose indicates free flowing characteristics of granules. Hardness of the tablet of every batch was in the range of 2.8 to 4.0Kg/cm2 Friability of all the tablets were less than 1%. Weight variation test results of every batch showed that the weight of each tablet of the batch tested was within the range ±7.5%. All the tablets formulated using Croscarmellose sodium, Crospovidone and Sodium starch glycolate disintegrated within 3minutes fulfilling the official limits of the Fast dissolving tablets. IR Spectral analysis suggests that the characteristic peaks of the Pure drug Telmisartan exist in the Spectra of Formulation prepared indicting the intactness of the drug is in intimate contact with the additives. It has not undergone any chemical interaction with the excipients used in the development of Telmisartan Fast dissolving tablets. Drug content uniformity study results showed that the drug Telmisartan was uniformly distributed throughout the formulation of every batch. Finally, we can conclude that, among various formulations prepared, the Fast dissolving tablets prepared, using Crospovidone (12mg) F6, disintegrated rapidly and gave highest dissolution of Telmisartan within a short period of time

Fungal Decolourization of Direct Azo Dyes and Biodegradation of Textile Dye Effluent

AbstractDecolourization of Direct azo dyes by fungi isolated from textile dye effluent was investigated. Seven different fungal species were isolated and identified. The fungal isolates were identified as Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus, Fusarium oxysporum, Penicillium chrysogenum, Mucor sp. and Trichoderma viride. The fungal inoculums were inoculated into flasks containing Direct azo dyes (500 mg/l) with trace amounts of yeast extract, glucose and sucrose and then sterilized and incubated for 12 days. Aspergillus niger completely decolourized the Congo Red within 6 days. The best decolourizer of Viscose Orange-A was Aspergillus fumigatus (88.70%). Mucor sp. (69.73%) was identified as the best decolourizer of Direct Green – PLS. The dye Direct Violet-BL was completely decolourized by Aspergillus niger within 9 days and Trichoderma viride within 12 days. The dye Direct Sky Blue-FF was completely decolourized by Aspergillus flavus within 9 days and Mucor sp. within 12 days. Penicillium chrysogenum have the capacity to completely decolourized the dye Direct Black-E within 12 days. Fungal biodegradation was assessed by physicochemical analysis

Bioadsorption of chromium resistant enterococcus casseliflavus isolated from tannery effluents.

Bioadsorption, bioaccumulation and enzymatic reduction are the processes by which the microorganisms interact with the toxic metals, enabling their removal or recovery. In the present study, a bacterial strain was isolated from tannery effluent and identified as Enterococcus casseliflavus. It showed a high level resistance of 800 µg/ml chromium. The minimal inhibitory concentration of chromium was found to be 512 µg/ml of potassium dichromate in Nutrient broth medium. The chromium adsorption was more significant by the live cells than killed cells at different time intervals. It was observed that, the inoculation of Enterococcus casseliflavus reduced the BOD and COD values of tannery effluent. The maximum adsorption of chromium was at a temperature of 35ºC to 45ºC and at a pH of 7.0 to 7.
