Uptake of tritiated thymidine by primordial germinal cells in the ovaries of the adult slender loris

Six adult lorises (Loris tardigradus lydekkerianus) in anoestrus were selected for study. Four of the animals were pretreated with an injection of 0·5 mg oestradiol-17β, two were given FSH (2 × 50 i.u. with a 12-hr interval), while the remaining two were not treated with hormones. All of the animals were subsequently given a subcutaneous injection of 0·5 mCi [3H]thymidine and their ovaries were recovered for autoradiography 24 hr later.It was found that the non-follicular germinal cells within 'nests' in the ovarian cortex actively incorporated the radioisotope. Some of the labelled germinal cells appeared to reach the pachytene-diplotene stages of meiotic prophase, although this would not be expected to occur in such a short time after treatment. None of the labelled germinal cells appeared to enter upon the phase of follicular growth, although a few (especially in ovaries treated with oestrogen and FSH) seemed to be in primordial follicles consisting of an incomplete layer of flattened cells

Implementation of a Modem for Narrow Bandwidth Channel Using 6713 DSK

As communication plays an important role in day to day life, the effective and efficient voice transmission is to be maintained. This paper mainly deals with voice transmission over a channel and implemented using 6713 DSK. For this purpose, some modulation schemes and voice coders are implemented. So two points of view are developed. First, a static point of view, using a prototype on MATLAB, estimates the different combinations\u27 performances, using a stored speech sample. Then, a more dynamic point of view tests the system in real time, using C code adapted from MATLAB and embedded on DSPs, with the actual transmission channel being emulated by another DSP. In MATLAB the voice signal using different techniques are simulated and the outputs for modulation and demodulation signal are obtained which are shown in this paper for random bits operation of signals. An optimal transmission/reception scheme intended for voice transmission on DSP Processor TMS320C6713 is done using hardware and the results are compared in MATLAB by maintaining proper accuracy

Generation of Optimal Switching Angle for Nine Level Cascaded H Bridge MLI Using Most Valuable Player Algorithm

Distributed generation (DG) sources often interfaced with grid by a Cascaded H-bridge multilevel inverter with a remote D.C source. The interface inverter has to adapt voltage on the either side of the grid and DG source while it has a control of active and reactive power exchange. The inverter terminal voltage is maintained based on frequency switching technique. However, in applications like micro grids are based on quality of output voltage at the point of common coupling. The present paper discusses an optimal frequency switching methodology that generates optimal fringing angle based on an evolutionary computing technique while maintaining the voltage level at PCC with a reduced harmonic distortion.  Efficacy of the proposed method is illustrated by simulating a 9-level cascaded H bridge in MATLAB environment

Development of Indigenous Pulse-Shape Discrimination Algorithm for Organic Scintillation detectors

The use of programmable hardware devices is imperative for digital based pulse shape discrimination (PSD) to differentiate between various types of radiation. This work reports the development of a PSD algorithm based on tail area and total area, eliminating the need for programmable hardware. The pulses were collected using BC501 detector and Pu-Be source from a digitizer in the oscilloscope mode. The algorithm performs crucial functions such as pulse normalization, shaping, identification and removal of multiple peaks and threshold determination. The algorithm provides neutron and gamma-ray counts, scatter plot, and FoM. In order to test the efficacy of our proposed algorithm, pulses were collected from a different source-detector setup comprising BC501A detector and an Am-Be source from a digitizer in the oscilloscope mode and Charge Integration (CI) mode. The results obtained from our proposed algorithm and CI method clearly indicates a good agreement in terms of number of neutrons and gamma-rays and Figure-of-Merit (FoM), thus providing cost-effective alternative method for neutron and gamma-ray discrimination, offering flexibility and accuracy without specialized hardware

A Review Paper on Smart Helmet : HelNet Smart Safety

The statistics of survey on road accidents from 2015 to 2019 in India says that on record, there are on average 472,606 road accidents. According to the BussinessStabdard.com report published on December 27, 2020 "6 two-wheeler riders die every hour in accidents" due to faulty helmet and poor enforcement of rules and regulation. In recent years, the number of two wheeler riders are increasing rapidly. Also, the annual sales of two-wheeler projects to reach 26.6 million by 2025 at 2.6% growth rate, according to UnivDatos. These accidents are due mainly due to drunk & drive, high density roads, poor or no communication of accidents which leads delay in medical aid. The normal helmet or should I say the older version or what we get in the market now a days. are good but it can be better. Since the technology is getting better day by day in lot of fields then why not in transportation field specially in the "two-wheeler transportation system" which gets more accident than any other vehicles on road. And our HelNet: A Smart Safety does the same. It checks the predefined norms first then only it lets the rider start it wheel. The monitoring of physiological signals using wearable devices is increasingly becoming a necessary for the assessment of the state of body and mind in natural environments. Following the same trends, many smart improvements are made in transportation system. Since the transportation is necessary so the safety of riders. With this in mind, helmets of two-wheeler riders are gone through lot of improvements throughout the years. UUnit that makes the rider compulsory to wear the helmet while driving. In spite these improvements, the road accidents are still increasing. The reasons for the accidents are human mistakes, violating traffic rules, usage of mobile phone or drunk. To overcome this issue, researchers worked by using the methods like auto ignition that motor did not start until the rider wear helmet on his head. The other sensors are also used to monitor the riders' safety and activities during riding the wheel. This project is built to aid people to monitor the various action such as accident detecting, navigating and many more. Although our project is not full replacement of manually checking hazards but our product will help in the occurrences, where a simple mistake could lead to a fatal outcome or things which are outside the natural field view of rider

Učestalost supkliničkog endometritisa u krava koje se pregone te usporedba učinkovitosti različite antibiotske i biljne intrauterine terapije

The present research work was conducted to investigate the incidence of subclinical endometritis (SE) in repeat breeder dairy cattle, and to study the comparative efficacy of different antimicrobial and polyherbal intrauterine therapies. Repeat breeding crossbred cows (>90 days in milking) with clear cervico-vaginal mucous discharge in spontaneous estrus were examined for uterine cytology by the cytobrush technique. The cows with ≥ 4% polymorphonuclear cells (PMNs) in uterine cytology were considered to be affected with SE. These cows were randomly and equally divided (n=12/group) into 5 groups and treated with the intrauterine medicine Vodine-IU (T1), Metricare-IU (T2), Utriguard-IU (T3), Uraksha (polyherbal preparation) (T4), or left untreated (control/C). In the subsequent estrus, uterine cytology was repeated and the cows were inseminated. The cows that failed to conceive but showed estrus were re-inseminated. The pregnancy status was checked. The incidence of SE was observed to be 36.80% (60/163). The PMNs percentage significantly declined in all the treatment group cows in response to treatment. The highest conception rate was observed in the T4 group (Uraksha treated) cows. It was concluded that the uterine cytobrush technique can be used efficiently for diagnosis of SE in dairy cattle, and polyherbal intrauterine drugs may be a good alternative in intrauterine antimicrobial therapy.Rad je proveden kako bi se istražila učestalost supkliničkog endometritisa (SE) u mliječnih krava koje se pregone. Također, usporedila se učinkovitost različitih antimikrobnih i poliherbalnih intrauterinih terapijskih postupaka. U krava koje se pregone (više od 90 dana u mužnji), s čistim cerviko-vaginalnim iscjetkom iz rodnice u spontanom estrusu, tehnikom citočetkice učinjena je citološka pretraga maternice. Za krave kod kojih je utvrđeno 4% polimorfonuklearnih stanica (PMN) smatralo se da imaju supklinički endometritis. Životinje su nasumično podijeljene u pet skupina s jednakim brojem jedinki (n=12 po skupini) i liječene intrauterino sljedećim lijekovima: Vodine (skupina T1), Metricare (skupina T2), Utriguard (skupina T3), Uraksha (poliherbalni pripravak; skupina T4), dok je peta skupina bila kontrolna skupina (C). U sljedećem estrusu ponovljena je citološka analiza maternice i krave su osjemenjene. Krave nisu ostale gravidne te su u sljedećem estrusu ponovno osjemenjene. Provjeren je status gravidnosti. Incidencija SE-a bila je 36,80 % (60/163). Postotak PMN-a znatno se smanjio u svih krava u tretiranim skupinama kao odgovor na liječenje. Najveća stopa koncepcije zabilježena je u krava u skupini T4 (liječene Urakshom). Zaključeno je da tehnika citočetkica može učinkovito poslužiti u dijagnostici SE-a u mliječnih goveda te da poliherbalni intrauterini lijekovi mogu biti dobra alternativa antimikrobnoj intrauterinoj terapiji

Assessment of Antisocial Behaviour in the Juveniles

Background: High level of crime, particularly by the people below 18 years, has been a matter of concern for many years. Assessing and preventing the antisocial behaviour in juveniles has become a policy priority.Methods: A cross sectional study was conducted on 52 males less than 18 years in an observation home in Bangalore, India. The data was collected in an interview by filling a semi structured questionnaire. Revised Wisconsin Delinquency Risk Assessment Scale (RWDRAS) was filled up simultaneously and then results were analysed.Results: Majority of the offenders were in the age group 16-18 years. In the majority the cause for antisocial behaviour was unknown followed by the family problems and poverty. The RWDRAS identified 47% of the juveniles with antisocial behaviour as low risk group.Conclusion: The Education, counselling and prevention of poverty are some of the preventive measures of antisocial behaviour. There is a need to develop a better criteria and scale for the diagnosis of antisocial behaviour as the presently used RWDRAS failed in 47% of the juveniles
