Laparoscopy Assisted Open Repair of Bilateral Abdominoscrotal Hydrocele in 8 Months Old Baby—Rare Case Report  [PDF]
Kalpesh Onkar Patil, Vaibhav Shah
Open Journal of Pediatrics (OJPed) , 2016, DOI: 10.4236/ojped.2016.64042
Abstract: Bilateral Abdominoscrotal Hydrocele (ASH) is very rare in children and difficult to suspect on clinical examination. Abdominoscrotal hydrocele (ASH) is very unusual presentation of scrotal hydrocele with dumbbell-shaped extension intra abdominally through deep inguinal ring either communicating to peritoneal cavity or non-communicating. No theory can explain exact development of ASH though many theories have been proposed in literature. An abdominoscrotal hydrocele is a congenital pathology involving a scrotal hydrocele expanding through the inguinal canal and reaching the abdominal cavity (pars abdominalis). A simple hydrocele is commonly diagnosed clinically, where as an abdominoscrotal hydrocele is rare and should be differentiated from other cystic lesions of the abdominal cavity in children.

Tipping time of a quantum rod

Physics , 2009, DOI: 10.1088/0143-0807/31/2/009
Abstract: The behaviour of a quantum rod, pivoted at its lower end on an impenetrable floor and restricted to moving in the vertical plane under the gravitational potential is studied analytically under the approximation that the rod is initially localised to a small-enough neighbourhood around the point of classical unstable equilibrium. It is shown that the rod evolves out of this neighbourhood. The time required for this to happen, i.e., the tipping time is calculated using the semi-classical path integral. It is shown that equilibrium is recovered in the classical limit, and that our calculations are consistent with the uncertainty principle.

Abstract: undescended testes or cryptorchidism in the most common congenital anomaly of male reproductive system. the descent is multifactorial with gubernaculums playing major role. the failure of descent can be at trans-abdominal or inguino-scrotal phase. locating undescended testes is important in view of low fertility and high rate of occurrence of neoplasm in them. ultrasound is the standard imaging technique of choice in children with a non-palpable testis as it is non-invasive and does not use ionizing radiation. position of testis is also important in deciding whether patient will need abdominal or inguinal exploration. the aim was to study the position of undescended testes by high frequency ultrasound and its embryonic explanation. total 41 boys with undescended testes underwent high frequency ultrasound. the location of testis was noted followed by its size and echotexture. thirty patients had unilateral and 11 had bilateral undescended testes. the prevalence was more on right side (16 out of 30). out of total 52, 46 (88%) testis were located by ultrasound. six (12%) testes could not be located. five (10%) were retractile testes. out of remaining 41, 26 (63%) were located in inguinal canal and 15 (37%) were located in abdomen. out of 15 abdominal testes 9 were located just proximal to inguinal canal and 6 were located in deep pelvis. high frequency ultrasound was able to locate the position of undescended testes in majority (88%) of the cases.

The failure of descent can be at trans-abdominal or inguino-scrotal phase. Locating undescended testes is important in view of low fertility and high rate of occurrence of neoplasm in them. Ultrasound is the standard imaging technique of choice in children with a non-palpable testis as it is non-invasive and does not use ionizing radiation. Position of testis is also important in deciding whether patient will need abdominal or inguinal exploration. The aim was to study the position of undescended testes by high frequency ultrasound and its embryonic explanation. Total 41 boys with undescended testes underwent high frequency ultrasound. The location of testis was noted followed by its size and echotexture. Thirty patients had unilateral and 11 had bilateral undescended testes. The prevalence was more on right side (16 out of 30). Out of total 52, 46 (88%) testis were located by ultrasound. Six (12%) testes could not be located. Five (10%) were retractile testes. Out of remaining 41, 26 (63%) were located in inguinal canal and 15 (37%) were located in abdomen.

High frequency ultrasound was able to locate the position of undescended testes in majority (88%) of the cases. La criptorquidia o testículos no descendidos es la anomalía congénita más común del sistema reproductivo masculino. El descenso es multifactorial, donde el gubernaculum testis juega un rol fundamental. El fracaso de descenso puede ocurrir en fase trans-abdominal o inguino-escrotal. Conocer la localización de los testículos no descendidos es importante en vista de la baja fertilidad y alta tasa de incidencia de neoplasia en ellos. La ecografía es la técnica imagenológica estándar y de elección en ni os con testículos no palpables, ya que no es invasiva y no utiliza radiación ionizante. La posición del testículo también es importante para decidir si el paciente necesita exploración abdominal o inguinal. El objetivo fue estudiar la posición de los testículos no descendidos por ultrasonido de alta frecuencia y su explicación embrionaria. Un total de 41 ni os con testículos no descendidos se sometieron a ultrasonido de alta frecuencia. Se estudió la ubicación, tama o y ecotextura del testículo no descendido. Treinta pacientes presentaron el testículo no descendido de manera unilateral y 11 bilateral. La prevalencia fu
Study of Signal Denoising using Kaiser Window and Butterworth Filter

Abstract: A signal in the communication system is the information containing part which is to be process, but during the processing of the signal some noise is added in the signal and signal becomes noisy. This is now mandatory to eliminate this noise from the signal to get information from the signal. In this paper, a wavelet filter based on Butterworth IIR filter and Kaiser Window FIR filter is designed for the signal analysis. Butterworth low pass IIR filter has limited application in signal denoising. It has maximally flat response in the pass band and, therefore, the filter has distorted output. It makes Butterworth filter little applicable in communication systems and other signal analysis technique. The newly designed matched wavelet filter presents a new concept for better signal analysis and disturbance detection in the communication systems. The limitation of Butterworth low pass filter in signal denoising and other applications can be eliminated by using this matched wavelet filter. We have improved performance in signal filtering by using Kaiser Wavelet filter. This Wavelet filter finds applications in signal analysis, communication system and image compression with a lot of other fields.
STUDY OF BIODIESEL AS A FUEL FOR CI ENGINES AND ITS ENVIRONMENTAL EFFECTS: A RESEARCH REVIEW
Mukesh Kumar,Onkar Singh
International Journal of Advances in Engineering and Technology , 2013,
Abstract: Biodiesel will play an increasing role in fulfilling the world’s energy requirement. The world has experienced negative effect from the fossil fuel such as global warming and acid rain etc. With the increase in consumption of biodiesel, its impact on environment has raised a discussion around the world. Energy requirement of the world will increase in coming future and is projected to increase by 50% from 2005 to 2030. The paper presents the results of biodiesel combustion emission on the environment. A review of literature available in the field of vegetable oil usage has identified many advantages. Vegetable oil is produced domestically which helps to reduce costly petroleum imports, it is biodegradable, nontoxic, contains low aromatics and sulphur and hence, is environment friendly. The biodiesel shows no obvious NOx emission difference from the pure diesel fuel at low and medium engine loads. Biodiesel blend ratios have little effect on the NO/NOx ratio at medium and high engine loads. The CO emission of biodiesel increases at low engine loads. The HC emissions show a continuous reduction with increasing biodiesel blend ratios. There is a good correlation between smoke reduction and the ratio of the biodiesel blends. The addition of biodiesel fuel increases formaldehyde emission. A series of engine tests, with and without preheating have been conducted using each of the above fuel blends for comparative performance evaluation. The results of the experiment in each case were compared with baseline data of diesel fuel. Significant improvements have been observed in the performance parameters of the engine as well as exhaust emissions, when lower blends of karanja oil were used with preheating and also without preheating. Karanja oil blends with diesel (up to K50) without preheating as well as with preheating, can replace diesel for operating the CI engines.
