Robustness Study of Fractional Order PID Controller Optimized by Particle Swarm Optimization in AVR System

In this paper a novel design method for determining fractional order PID (PIλDµ) controller parameters of an AVR system using particle swarm optimization algorithm is presented. This paper presents how to employ the particle swarm optimization to seek efficiently the optimal parameters of PIλDµ controller. The robustness study is made for this controller against parameter variation of AVR system. This work has been simulated in MATLAB environment with FOMCON (Fractional Order Modeling and Control) tool box.The proposed PSOPIλDµ controller has superior performance and robust compared to GA tuned PIλDµ controller. The results are also compared with PSO tuned PID controller

Effect of organic mulches and foliar spray of kaolin on NPK uptake in enhancing yield and economics of dry land maize (Zea mays L.)

The hot and semi-arid region is prone to meteorological droughts; the lack of rain is frequently accompanied by hot temperatures, strong winds, and low humidity, which has the impact of limiting nutrient uptake and agricultural yields. To overcome this problem a field study conducted during June, 2020 kharif season at farmers field, Chinna Dudyala village, Muddanur, Kadapa district, Andhra Pradesh aimed to determine the effect of organic mulches and foliar spray of kaolin on NPK uptake in enhancing yield and economics of dry land maize (Zea mays). One of the most important techniques for preserving soil moisture was mulching, which also reduces evapotranspiration when anti-transpirants are used. The experiment comprised nine treatments (T1 to T9) with four types of organic mulches viz., Paddy straw, Ground-nut haulm, Coir-pith, and Sugarcane trash, with foliar spray of kaolin intervals on 40 DAS, 20 & 40 DAS and farmers practice to minimize water stress and improve the nutrient uptake by plant. Among the application of the treatments, coir-pith mulch + foliar spray of kaolin @ 3.0% (T6) on 20 DAS & 40 DAS had significant effect on NPK uptake with N (187.15 kg ha-1), P (69.60 kg ha-1) and K (156.22 kg ha-1) and enhanced grain yield (6976 kg ha-1) and stover yield (10980 kg ha-1), highest gross returns (138034 ₹. ha-1) and BCR (2.63) and was superior to all the other treatments. The present study would help to effectively utilise the available resources, enhance growth and productivity in maize crop and to make economically viable to the farmers of semi-arid regions

van der Woude syndrome- a syndromic form of orofacial clefting

van der Woude Syndrome is the most common form of syndromic orofacial clefting, accounting for 2% of all cases, and has the phenotype that most closely resembles the more common non-syndromic forms. The syndrome has an autosomal dominant hereditary pattern with variable expressivity and a high degree of penetrance with cardinal clinical features of lip pits with a cleft lip, cleft palate, or both. This case report describes van der Woude syndrome in a 19 year old male patient with a specifi c reference to the various aspects of this condition, as clinical appearance, etiological factors (genetic aspects), differential diagnosis, investigative procedures and management

IMPACT OF PHARMACIST LED ANTICOAGULATION MONITORING AND PATIENT EDUCATION ON ORAL ANTICOAGULATION THERAPY WITH ACENOCOUMAROL

  Objective: Acenocoumarol is anoral anticoagulant with narrow therapeutic index, and the ideal dose of anticoagulation lies between International normalized ratio (INR) values of 2.0 and 3.5. Lack of monitoring and knowledge on acenocoumarol therapy may compromise patient's safety resulting in under- or over-anticoagulation. A study was conducted to monitor for the safety of anticoagulation therapy, achievement of goal INR levels and to assess the impact of pharmacist led anticoagulation monitoring and patient education on the rational use of acenocoumarol in patients admitted in cardiology wards with thromboembolic disorders.Methods: The study was conducted in 70 patients; data collection was done, prescriptions were analyzed for drug-drug interactions and adverse drug reactions (ADRs). Patients' knowledge on acenocoumarol therapy was assessed using a self-developed questionnaire at the baseline, then were subjected to a detailed patient education and on an average each patient received three sessions of education. They were again made to answer the same questionnaire on the day of discharge. The mean score of the responses before and after education was compared statistically using Wilcoxon signed rank test and McNemar test.Results: There were 60% patients under anticoagulated with the INR range of >2.0. 123 drug interactions were observed in 58 patients, on an average of 2 interactions per prescription, but no ADRs were observed. 59 patients (84.3%) showed significant overall improvement in knowledge on anticoagulation therapy following education.Conclusion: This study implies the role of clinical pharmacists in achieving better clinical outcomes in patients receiving oral anticoagulation therapy with acenocoumarol

Nanocomposite Hydrogels for Wastewater Treatment

The insufficient access to drinking water is one of the most prevailing problems throughout the world. It is highly essential for future demands to bring wastewater to reusable form. Hence, water purification has been the focus and attention of many scientists and governmental agencies. The combination of adsorption and nanotechnology-oriented approach with conventional treatment methods has offered interesting benefits to treat waste water. During the last decade, hydrogels have been used as potential adsorbents for the removal of different types of water pollutants. The combination of hydrogels and nanomaterials with multifunctional framework leads to the development of hybrid hydrogels that gives synergistic effect to the novel materials. Because of their biocompatibility and ability to mix with other materials, hydrogels coupled with versatile chemical groups with well-defined three-dimensional porous structure were potentially used for removal of toxic pollutants in water. This article briefly reviews the recent progress in nanobased hydrogels with particular emphasis on wastewater treatment applications. © 2022 Author(s)

Oral hygiene practices and habits among dental students and staff in a dental college, India.

Introduction: Oral health is an essential component of general health in one's life. Oral self practices are very effective in keeping up one's good oral health from an individual's point of view. Such hygienic conditions prevent many oral diseases from happening or control them from damaging oral health adversely. Aim: To investigate the oral hygiene practices and habits among dental students and staff in a dental college. Materials and methods:  A survey with the aid of specially designed questionnaire was made anonymously, in order to assess the oral health behaviour among these people. Results: A number of 425 dental students as well as faculty members was investigated. Only 34.9% of students and faculty members are following oral self health habits strictly.    It was also observed that the staff members were very much concerned about oral hygiene rather than students were. Conclusion: The results show that dental students need a lot of awareness in their oral self hygiene.  Awareness programmes  must be conducted frequently to boost up the oral self hygiene practices among them for many good reasons

Effect of Sintering Temperature on the Magnetodielectric Performance of Nickel Ferrite

Nickel ferrite (NiFe2O4) nanopowder has been synthesized by a sol-gel auto-combustion process and further sintered at various sintering temperatures. The sintered samples were characterized by XRD, SEM and VSM. Enhancement of apparent density of the sample has been observed with the increase in sintering temperature and has a great influence on the magnetic and dielectric properties of NiFe2O4. The SEM results reveal that the grain size increases with increasing sintering temperature. The electrical resistivity decreases and the dielectric constant increases with increasing sintering temperature has been observed. The magnetic studies shown that the ferrimagnetic behaviour increases with sintering temperature. These results suggest that sintering temperature has a prominent effect on the magnetodielectric properties. © 2022 Author(s)
