A PACS alternative for transmitting DICOM images in a high latency environment

Picture Archiving and Communication System(PACS) is responsible for storing Digital Imaging and Communication in Medicine (DICOM) images fromradiology modalities into its database, images takes a lot of time to transfer to remote location through WAN due to large file size and slow transfer protocol. A PACS alternative system has been developed which performs basic functions of a generic PACS. Images directly from modalities are large in size by default transfer syntax of these images is Endian Explicit syntax. Changing this transfer syntax to lossless JPEG 2000 decreases the file size and because of lossless compression quality of image is still same as original image. These compressed images are then copied into Network Attached Storage working as PACS alternative. A series of test conducted in lab with multiple transfer protocol on Network Attached Storage (NAS) to find out which transfer protocol is faster under moderate speed and high latency network

Effect of Seed Disinfectants on in vitro Seed Germination and Seedling Development in Eggplant

The present investigation reports effects of disinfectants on culture contamination, seed germination and seedling growth in eggplant. Mercuric chloride hampers seed germination when seeds are treated with 0.1% solution above 2 min duration and lesser durations are not helpful in controlling in vitro contamination. The highest seed germination (89.97%) was recorded with 50% commercial bleach for 20 min in the genotype BL-3, followed by BR-16 (88.53%), BR-14 (86.19%), BL-5 (86.16%) and BSR-23 (85.57%). However, least number of seeds germinated in BR-18 (10.94%), BSR-25 (13.27%) and BL-7 (18.62%) when disinfected with 75% commercial bleach for 25min. Overall results revealed that 50% commercial bleach concentration (73.76%) was better than 75% (36.85%), and 20 min duration (60.82%) was better than 25 min (49.80%) for seed disinfection. Among the varieties, BL-3 was at the top (68.85%) and BR-18 at the lowest (34.16%) edge for per cent seed germination. Seedling growth (cm) with use of commercial bleach was quite satisfactory compared to disinfection with HgCl2, where, 50% commercial bleach favored a good stand of plant lets even after 10 days, showing a healthy root (3cm), hypocotyl (5cm) and cotyledons (1.5cm)

Genetic variability in CMS backcross generations and their maintainers in eggplant (Solanum melongena L.)

Twelve genotypes of eggplant in BC3, BC4 and BC5 generations of CMS-lines derived from Solanum ae-thiopicum × Solanum melongena cross along with their maintainers were evaluated for eighteen quantitative charac-ters at Punjab Agricultural University Ludhiana. Analysis of variance depicted significant variation (P ? 0.05) for all the characters in all generations. High PCV and GCV values were observed for fruit length, fruit girth, fruit weight, number of fruits plant-1 and yield plant-1 in all generations indicating high variability in the germplasm. High heritability coupled with high genetic advance was found for peduncle length, fruit length, fruit girth, fruit weight, number of fruits plant-1 and yield plant-1 in all generations indicating the predominance of additive gene action for these traits. Thus, selections can be made from present germplasm for the development of improved CMS inbred lines with varying fruit traits

Metabolomics characterization of Senna tora (L.) Roxb. using different approaches

The present study aimed to investigate the variety of elements, chemical compounds and their corresponding functional groups in the whole plant, leaves, and seeds of Senna tora. A preliminary phytochemical analysis has revealed the presence of secondary metabolites including alkaloids, flavonoids, tannins, terpenoids, cardiac active glycosides, phenolics, etc. Gas Chromatography and Mass Spectrophotometry (GC-MS) analysis of leaves and seeds of S. tora has depicted 31 and 27 compounds, respectively. Fourier Transform Infrared (FT-IR) Spectroscopy has further unveiled the presence of different functional groups such as amines, aromatic compounds, carboxyl groups, ketones etc. associated with different metabolites. Wavelength Dispersive X-ray Fluorescence (WD-XRF) has revealed the presence of more than 20 elements (macro and micro) including Ca, Mg, Fe, K, etc. This study has highlighted the detailed account of the chemical compounds and elements present in the plant species under investigation and substantiated its medicinal importance in the traditional health care system

Near simultaneous measurements of NO2 and NO3 over tropics by ground-based absorption spectroscopy

The present study concentrates on measurements of NO2 and NO3. NO2 has been measured during twilight period using zenith sky absorption spectrometric technique in the 436 to 448 nm region. NO3 has been measured during night time using direct moon as a source of light in the 655 to 667 nm region. These measurements have been taken at low latitude station, Ahmedabad (23 deg N, 76 deg E), India for the past two years

The effect of stress fracture occurring within the first 12 months of training on subsequent race performance in Thoroughbreds in Hong Kong

BACKGROUND Racehorses are at an increased risk of stress fracture within the first 12 months of racing and when resuming training after a break. Research in these high-risk periods and on the effect of performance post-recovery is limited. OBJECTIVES To describe the occurrence of stress fractures, diagnosed by nuclear scintigraphy (NS), in racehorses' first 12 months training in Hong Kong, and their impact on racing performance and career length. STUDY DESIGN Retrospective 1:2 matched case-control study. METHODS Clinical records of horses with NS-diagnosed stress fractures within 365 days of import between 2006 and 2018 were collated. Cases and controls were matched on import date. Univariable conditional logistic regression compared signalment, pre-fracture training and post-recovery racing performance between cases and matched controls. Shared Frailty Cox regression analysed time from import to fracture and total career length. RESULTS Eighty-seven horses sustained a NS-diagnosed fracture within their first year in Hong Kong (incidence risk 1.7% (95% confidence interval (CI) 1.4-2.1%; N=5,180)). The humerus (42.0%; 95% CI 31.8-52.6%; n=39) and tibia (28.0%; 95% CI 19.1-38.2%; n=26) were most common stress fracture sites. Cases missed a median of 63 days (Interquartile range (IQR) 49-82) of training because of fracture. Within the 12 months following diagnosis, case horses had a median of four (IQR 2-4, p<0.0001) fewer race starts and were down HK$206,188 (IQR HK$0-436,800, p=0.007) in race earnings compared to controls. Career length did not significantly differ between cases and controls (median 2 years and 3 months; IQR 15.3-39.1 months; p=0.2). MAIN LIMITATIONS Only stress fractures diagnosed by NS were included, hence, the study is not representative of all stress fractures occurring in racehorses in Hong Kong. CONCLUSIONS Racehorses sustaining a stress fracture within one year of entering Hong Kong lost significant time in training, earnings and race starts. However, overall career length was unaffected

Role of contrast-enhanced ultrasound (CEUS) in paediatric practice: an EFSUMB position statement

The use of contrast-enhanced ultrasound (CEUS) in adults is well established in many different areas, with a number of current applications deemed off-label, but the use supported by clinical experience and evidence. Paediatric CEUS is also an off-label application until recently with approval specifically for assessment of focal liver lesions. Nevertheless there is mounting evidence of the usefulness of CEUS in children in many areas, primarily as an imaging technique that reduces exposure to radiation, iodinated contrast medium and the patient-friendly circumstances of ultrasonography. This position statement of the European Federation of Societies in Ultrasound and Medicine (EFSUMB) assesses the current status of CEUS applications in children and makes suggestions for further development of this technique

Gas phase production of NHD2 in L134N

We show analytically that large abundances of NH2D and NHD2 can be produced by gas phase chemistry in the interiors of cold dense clouds. The calculated fractionation ratios are in good agreement with the values that have been previously determined in L134N and suggest that triply-deuterated ammonia could be detectable in dark clouds. Grain surface reactions may lead to similar NH2D and NHD2 enhancements but, we argue, are unlikely to contribute to the deuteration observed in L134N.Comment: 6 pages, 2 figures, uses psfig.sty and emulateapj.sty, to appear in Astrophysical Journal, vol 55
