Effects of different vibration frequencies, amplitudes and contraction levels on lower limb muscles during graded isometric contractions superimposed on whole body vibration stimulation
Background: Indirect vibration stimulation, i.e., whole body vibration or upper limb vibration, has been investigated increasingly as an exercise intervention for rehabilitation applications. However, there is a lack of evidence regarding the effects of graded isometric contractions superimposed on whole body vibration stimulation. Hence, the objective of this study was to quantify and analyse the effects of variations in the vibration parameters and contraction levels on the neuromuscular responses to isometric exercise superimposed on whole body vibration stimulation. Methods: In this study, we assessed the 'neuromuscular effects' of graded isometric contractions, of 20%, 40%, 60%, 80% and 100% of maximum voluntary contraction, superimposed on whole body vibration stimulation (V) and control (C), i.e., no-vibration in 12 healthy volunteers. Vibration stimuli tested were 30 Hz and 50 Hz frequencies and 0.5 mm and 1.5 mm amplitude. Surface electromyographic activity of the vastus lateralis, vastus medialis and biceps femoris were measured during V and C conditions with electromyographic root mean square and electromyographic mean frequency values used to quantify muscle activity and their fatigue levels, respectively. Results: Both the prime mover (vastus lateralis) and the antagonist (biceps femoris) displayed significantly higher (P < 0.05) electromyographic activity with the V than the C condition with varying percentage increases in EMG root-mean-square (EMGrms) values ranging from 20% to 200%. For both the vastus lateralis and biceps femoris, the increase in mean EMGrms values depended on the frequency, amplitude and muscle contraction level with 50 Hz-0.5 mm stimulation inducing the largest neuromuscular activity. Conclusions: These results show that the isometric contraction superimposed on vibration stimulation leads to higher neuromuscular activity compared to isometric contraction alone in the lower limbs. The combination of the vibration frequency with the amplitude and the muscle tension together grades the final neuromuscular output.Peer reviewe
Echolocation by Quasiparticles
It is shown that the local density of states (LDOS), measured in an Scanning
Tunneling Microscopy (STM) experiment, at a single tip position contains
oscillations as a function of Energy, due to quasiparticle interference, which
is related to the positions of nearby scatterers. We propose a method of STM
data analysis based on this idea, which can be used to locate the scatterers.
In the case of a superconductor, the method can potentially distinguish the
nature of the scattering by a particular impurity.Comment: 4+ page

A clinico-surgical outcome of vaginal hysterectomy with or without hydro dissection: a Quasi experimental study
Background: Vaginal hysterectomy -the signature operation of gynecologic profession, is a hallmark of gynecological extirpative hysterectomy surgery and surgical excellance1. In the era of minimal invasive surgery, Nondescent vaginal hysterectomy has evolved over the years and is opted over abdominal route. It is because of lower morbidity, less postoperative pain, more rapid return to normal activities and lesser hospital stay associated with this route of surgery. Practice of hydrodissection with diluted adrenalin has been noticed by few surgeons.Methods: We did a retrospective analysis of 267 cases of vaginal hysterectomies in our hospital over a period of three years, regarding the benefit of hydro dissection in reducing the blood loss and time of surgery, so as to incorporate this technique on routine basis.Results: Of 267 cases, NDVH was done in 107 (40.1%) cases, and 160 (59.9%) patients underwent vaginal hysterectomy with PFR. Of 267 cases, 121 (45.3%) cases had hydro dissection. In 146 (54.7%) cases hydro dissection was not done. The mean blood loss was significantly reduced in cases with hydro dissection to a mean of 1.07 mops when compared to cases with no hydro dissection-mean of 1.71 mops. Duration of surgery was also significantly reduced to a mean of 39.9 minutes in cases with hydro dissection when compared to cases with no hydro dissection with a mean of 46.3 minutes. There was no significant change in duration of hospital stay.Conclusions: Hydro dissection with diluted adrenaline should be routinely practice by all vaginal surgeons to reduce the duration of surgery and intraoperative blood loss
ROLE OF DHUMAPANA (NEBULIZATION) AND PANA WITH ARDRAKA ARKA IN THE MANAGEMENT OF TAMAKA SHWASA
Tamaka Shwasa is one among the major disease explained in Ayurveda is caused due to vitiation of Kapha and Vata dosha in Pranavaha srotas. The condition is analogous to bronchial asthma as explained in modern medical science. India has an estimated 15-20 million Asthmatics every year and the disease occurs at very young age that survey states one in every six child under the age of 16 is affected.Asthma is characterized by recurrent attacks of breathlessness and wheezing which vary in severity and from person to person. It is a chronic condition, which frequently requires continuous medical care, comprising of different routes of administration and the important one is the inhalation route which has been developed to administer the drugs by delivering to site of action and to get immediate effects. Most of our Acharyas have explained different treatment modalities in the management of Tamaka Shwasa that consists of Shodhana, Shamana and Tarpana, but the concept of ‘Arka prayoga’ is explained in Arka Prakasha which stands unique. The book written by Ravana has explained different drugs used to prepare Arka (Extraction of active principles through the distillation process), its preparation method, qualities and application of Arka on different diseases internally as Pana along with its dosage in detail. In the study during the attack of Shwasa one group was administered Ardraka arka pana and the second group was administered Dhumapana (inhalation) with Ardraka arka by Nebulization method to conceptualize the study and parallel new perspective to rising trend in management of asthma in exacerbated condition. Statistical significance of selected criteria showed highly significant results in Dhumapana (Nebulization) by proving that natural therapies like Ayurveda can provide a better direction in improving the quality of life of Shwasa patients without any adverse effects of medications

Text Extraction and Localization From Captured Images
Extraction of text contents from image is tedious task because of variance in the font size, style, Orientation, Alignment and heterogeneous nature of text. The contents of text information in the scene images hold valuable data. The framework uses 2-d Wavelet transform using HAAR is applied to the grayscale image followed by edge detection for each sub-band filtering. Then region clustering technique is applied using centroids to each region. Further bounding box is fit to each region thus identifying the text components. Proposed framework is removing non-text content and separated text-content, then each text contents are converted into editable text using OCR engine. Here, we use Teserract recognition engine
Maternal and perinatal outcome in placenta previa in atertiary care centre: a record based retrospective case series study
Background: Placenta previa occurs when the placenta is situated wholly or partially in the lower uterine segment. It is one of the leading causes for maternal and perinatal morbidity and mortality. It occurs in 4 to 5 cases out of 1000 pregnancies and remains a significant cause for maternal and perinatal morbidity and mortality. Objective of this study is to know the maternal and perinatal outcome in placenta previa.
Methods: It is a retrospective case series study. Data of 51 pregnant women diagnosed with placenta previa managed at SNMC and HSK hospital between January 21 to December 22 were retrieved and analyzed.
Results: Incidence of placenta previa was found to be 1.6% of 3135 deliveries at the given time. Among 51 cases of placenta previa, 7.84% delivered vaginally, 92.16% underwent caesarean section. 45.10% were early preterm, 29.41% had late preterm delivery, 25.49% had term deliver, 49.02% had h/o previous LSCS, 7.8% had history of d and e, 17.65% had h/o abortion, 11.76 % still born. Blood transfusion was done for 27.45% of women, post-partum haemorrhage was documented in 21.56%, 7.84% needed ICU admission and there were no documented peri-partum hysterectomy upon any of these women.
Conclusions: The availability of advanced emergency obstetric care across greater number of referral hospitals has been responsible to decrease the morbidity and mortality associated with many complicated obstetric conditions. However the challenge is that as this condition is confirmed by ultrasound, women should take regular antenatal check-ups, should be counselled and made aware of the complications associated with this condition so that adequate and appropriate management can be planned and executed for better maternal and perinatal outcome also with on time referral to tertiary care centre where there is required multidisciplinary team, adequate availability of blood and blood products, NICU and ICU facilities where these high risk caesarean be managed efficiently the potential to limit maternal and perinatal mortality and morbidity caused due to placenta previa can be greatly reduced
