Chromatographic finger print analysis of budmunchiamines in Albizia amara by HPTLC technique
T. Rajkumar, B.N.Sinha
International Journal of Research in Pharmaceutical Sciences , 2010,
Abstract: Recently, there has been an increase in the use of herbal drugs for healthcare. Herbal Medicine is a time-tested and valuable resource for healing. In India, the herbal drug market is about $ one billion and the export of plant based crude drugs is around $ 80 million. So it is absolutely essential to provide scientifically proven and evidence based herbal formulations for global acceptance. Chromatographic fingerprint symbolize the active chemical constituents of herbal medicines for desired therapeutic action. This study presents a simple, rapid and selective HPTLC method for separation and determination of Albizia amara. Albizia amara (Fabaceae) is the medicinal plant which has been used to treat piles, diarrhoea, gonorrhoea, leprosy, and leucoderma. The macro cyclic alkaloid Budmunchiamines is the main constituent which has been separated and identified by camag HPTLC. The coarsely dried powdered leaves were extracted with Petroleum Ether (60-80)0C by cold maceration, and hot percolation with 90% methanol for 72 h. TLC profile and HPTLC fingerprints were recorded by using silica gel GF254 as stationary phase. Separation was performed on pre-coated 10x10cm HPTLC Aluminium sheets. Sample volumes of (5μl) were applied to the 6 tracks contain bandwidth of 5mm and 10 secs/μl using a TLC applicator. The plates were developed using a mobile phase of Chloroform: diethylamine (86:22 v/v). The peak 2, 6 reveals that the presence of macro cyclic alkaloids Budmunchiamines L4, L5 were characterised and confirmed by FTIR, 1H NMR, MASS and CHN analysis. The results were compared with earlier reports. The developed HPTLC fingerprints will help the manufacturer for quality control and standardization of herbal formulations.
The Importance of Extensor Mechanism in the Success of Patello-Femoral Arthroplasty  [PDF]
Rajkumar Krishnan, Ray Randle
Open Journal of Orthopedics (OJO) , 2014, DOI: 10.4236/ojo.2014.48036
Abstract: Anterior knee pain is a common symptom in general orthopedic practice and is reported in 8% of women and 2% of men over the age of 55 years. The treatment of isolated patellofemoral arthritis is controversial. Many patients can be effectively managed conservatively. Analysis was done on 14 patients (17 knees) with symptomatic isolated patellofemoral osteoarthritis between 2001 and 2007. 3 patients had additional procedures like tibial tubercle osteotomy and lateral release, tibial tubercle osteotomy with medical plication and iliotibial band lengthening and lateral retinacular release. The operation should be viewed as a soft-tissue procedure involving resurfacing of the femoral trochlea and the articular surface of the patella. Proper balance of the extensor mechanism must be done at the time of surgery to ensure correct tracking of the patella which in turn results in the best outcome for the replacement.

Abstract: A 65-year-old multi-gravida presented with complaints of abdominal pain and postmenopausal bleeding per vagina for seven months. Her past medical history was insignificant with no history of tuberculosis, inflammatory conditions of the uterus or iatrogenically introduced substances in uterus. She had attained menopause about 15 years back.Gynecological examination revealed atrophic ectocervix flushed with vagina. The vagina appeared normal. Uterus was bulky of around 12 weeks and adnexae were unremarkable. Colposcopy showed schiller's unstained areas on anterior lip of cervix. Ultrasound abdomen showed endometrial thickness of 2.6 cms. and fluid in the endometrial cavity. Ectocervical biopsy showed strips of moderate to severe dysplastic stratified squamous epithelium. Endometrial curetting revealed strips of stratified squamous epithelium showing moderate dysplastic changes. No normal endometrium was seen. The pyometra was drained, following which the patient underwent type-II radical hysterectomy. The procedure was well tolerated and the postoperative period was uneventful.The hysterectomy specimen revealed thickened and widened endometrial cavity with gray white nodule in the sub-adjacent myometrium. The cervix showed no obvious growth. The cut-section of the right fallopian tube showed thickened mucosa. Both the ovaries did not show any gross abnormality.The sections revealed entire endometrium replaced by stratified squamous epithelium showing areas of heavy keratinization, koilocytic changes, nuclear hyperchromasia and moderate increase in nuclear-cytoplasmic ratio indicating low grade dysplastic changes in underlying ichthyosis uteri (Fig 1). Extensive sampling of endometrium revealed few atrophic endometrial glands beneath the dysplastic squamous epithelium (Fig 2). Focal invasive islands of atypical squamous epithelial cells were seen in superficial myometrium (Fig 3). In addition, myometrium showed few foci of adenomyosis. Section from the cervix showed mo
Load Frequency Control Using Optimal PID Controller for Non-Reheat Thermal Power System with Tcps Unit

International Journal of Engineering and Advanced Technology , 2012,
Abstract: The main objective of Load Frequency Control (LFC) is to regulate the power output of electric generator within an area, in response to the changes in system frequency and tie-line loading. Thus, LFC helps in maintaining the scheduled system frequency and tie-line power interchange with other areas within the prescribed limits. Most LFCs are primarily composed of an integral and PID controller. The integrator gain is set to a level that compromises between fast transient recovery and low overshoot in the dynamic response of the overall system. This type of controller is slow and does not allow the controller designer to consider the possible changes in operating condition and non-linearity in the generator unit. Moreover, it lacks in robustness. FACTS are designed to overcome the limitations of present non-reheat thermal-thermal power systems and enhance the power system stability. One of the promising FACTS devices is the Thyristor controlled phase shifter (TCPS) to alleviate this difficulty. TCPS is connected in the tie-line to self-tune the parameters of integral and PID controller. Two area system, have been considered for simulation of the proposed TCPS connected integral and PID controller .The performance of the Conventional controller, TCPS connected Integral and PID controller have beenCompared through MATLAB Simulation. The qualitative and quantitative comparisons have been carried out for Integral, PID controllers. The dynamic of performanceresponses of Integral and PID controller with TCPS shows that in terms of settling Time, peak overshoot and steady state error are greatly improved than that of without TCPS.

Boiled Water Temperature Measurement System Using PIC Microcontroller
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: The measurement system for temperature of boiled water is a critical task in industry. In this paper we designed and implemented a PIC micro controller based boiled water temperature measurement system using PIC 18F452 and national semiconductors LM35 temperature sensor. The designing system is used to measure the tank I boiled water temperature value. If the temperature value reaches the set value high temperature relay board becomes ON to control the solenoid valve. The high temperature of the boiled water which flows through the metal pipe I is lowered by spraying the cool water using control valves. The valves are controlled by manually depends upon the requirement of temperature. Thus the output is obtained by reducing high temperature. Low temperature water is collected in tank III. Here, after comparing the reduced temperature value water with programming of temperature set value, the collected cooling water is ready for supplying to various purposes in the industry plants.
