Line Pattern Removal and Enhancement Technique for MultichannelPassive Millimeter Wave Sensor Images
Passive millimeter wave (PMMW) imaging systems have attracted an increasing interestover the past years due to their superior poor-weather performance compared with visible andIR systems. In passive imaging, the spatial information acquired is strictly band-limited. A majordrawback to PMMW images is their poor angular resolution. Also, another problem of single-channel PMMW imaging systems is the slow response time due to the lack of thermal sensitivity.The imager could operate at TV (television) rates using a number of parallel channels which mayreduce the extent of this problem. In multi-channel, differences between the responses of individualchannels can introduce noise into the image, which can obscure details of interest. The proposednoise-removal technique is a two-pass combined method of two techniques. One technique isfor removing the DC component in the frequency domain and the other one is statistical filteringbased on homogeneous region in the image (spatial) domain, followed by high-boost filteringby 3×3 mask for enhancement the image. High quality images are presented to demonstrate thepotential of this technique
Genetic variability and correlation analysis in F2 segregating population in brinjal (Solanum melongena L.)
Genetic advance denotes the improvement in the mean genotypic values of selected families over the base population. Thus, it helps the breeder select the progenies in the earlier generation. The objective of the study was to analyse the heritability, genetic advance and genetic variability for ten traits in brinjal contributing to fruit yield were studied in the F2 population obtained from the cross of Sevathampatti local x Seetipulam local. The study examined the subsistence of a significant extent of genetic variability for the traits considered. The characteristics of brinjal exhibited higher values of genotypic variation (GCV), viz., the height of the plant (20.93), yield per plant (17.42), number of branches (22.73) and shoot infestation (56.39) and phenotypic coefficient of variation (PCV) viz., the height of the plant (21.10), yield per plant (22.32), number of branches (23.42) and shoot infestation (57.24). However, the number of branches (45.44 %), height of the plant (42.76%), number of fruits (38.58%), fruit yield (28.02%) and shoot infestation (114.4%) exhibited high estimates of genetic advance and heritability for plant height (98.36), number of branches per plant (94.19) and shoot infestation (97.06). These characteristics can be effectively improved through selection. Association analysis mentioned that the yield of the fruit was significantly and positively correlated with the number of fruits, number of branches, individual fruits per plant and fruit girth. Direct selection may be executed because of these characteristics as the key choice of criteria to minimize the indirect result of additional traits throughout the improvement of high yielding varieties
Studies on the activities of antioxidant enzymes under induced drought stress in in vivo and in vitro plants of Macrotyloma uniflorum (Lam.) Verdc.
Activities of glutathione reductase, guaiacol peroxidase, catalase and contents of ascorbic acid, Hydrogen peroxide were analysed in in vitro and in vivo plants of Macrotyloma uniflorum under Polyethylene glycol (PEG) induced drought condition. Water stress was induced in in vitro plants by supplementing the regeneration medium with PEG (Mol. Wt. 6000) at the concentrations ranging from 5 to 25% while in in vivo plants by watering PEG solution with the same concentrations. The activities of glutathione reductase and guaiacol peroxidase were increased under induced drought stress condition in both treated samples. On contrary, catalase activities were decreased. The contents of ascorbic acid and hydrogen peroxide were enhanced correspondingly as the concentration of the PEG increased from 5 to 25%. The role of antioxidant enzymes under water stress condition is discussed. Further, the feasibility of mining the novel genes of drought resistance from the in vitro plants of Macrotyloma uniflorum is highlighted
1-[3,5-Bis(trifluoromethyl)phenyl]-3-[(5-ethenyl-1-azabicyclo[2.2.2]octan-2-yl)(6-methoxyquinolin-4-yl)methyl]thiourea–l-proline–methanol (1/1/1)1
In the methanol solvate of the title 1:1 cocrystal, C29H28F6N4OS·C5H9NO2·CH4O, the l-proline molecule exists as a zwitterion. In the crystal, the disubstituted thiourea, l-proline and methanol molecules are linked by N—H⋯O and N—H⋯N hydrogen bonds, forming a two-dimensional array in the ab plane
(5-Ethenyl-1-azabicyclo[2.2.2]octan-2-yl)(6-methoxy-3-quinolyl)methanol methanol solvate
In the title methanol solvate, C20H24N2O2·CH4O, an L-shaped conformation is found as the two substituents at the central hydroxy group are almost orthogonal to each other [the C—C—C angle at the central sp
3-C atom is 110.12 (13)°]. The most notable feature of the crystal packing is the formation of supramolecular chains along the b direction mediated by O—H⋯N hydrogen bonds occurring between the hydroxy and quinoline N atoms; the methanol molecules are linked to these chains via O—H⋯Namine hydrogen bonds. C—H⋯O interactions also occur

An intramolecular C—H⋯N hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by C—H⋯π and π–π interactions [centroid–centroid distances of 3.688 (2), 3.656 (1) and 3.716 (2) Å]
Persistent circulation of a fluoroquinolone-resistant Salmonella enterica Typhi clone in the Indian subcontinent.
BACKGROUND: The molecular structure of circulating enteric fever pathogens was studied using hospital-based genomic surveillance in a tertiary care referral centre in South India as a first genomic surveillance study, to our knowledge, of blood culture-confirmed enteric fever in the region. METHODS: Blood culture surveillance was conducted at St John's Medical College Hospital, Bengaluru, between July 2016 and June 2017. The bacterial isolates collected were linked to demographic variables of patients and subjected to WGS. The resulting pathogen genomic data were also globally contextualized to gauge possible phylogeographical patterns. RESULTS: Hospital-based genomic surveillance for enteric fever in Bengaluru, India, identified 101 Salmonella enterica Typhi and 14 S. Paratyphi A in a 1 year period. Ninety-six percent of isolates displayed non-susceptibility to fluoroquinolones. WGS showed the dominant pathogen was S. Typhi genotype 4.3.1.2 (H58 lineage II). A fluoroquinolone-resistant triple-mutant clone of S. Typhi 4.3.1.2 previously associated with gatifloxacin treatment failure in Nepal was implicated in 18% of enteric fever cases, indicating ongoing inter-regional circulation. CONCLUSIONS: Enteric fever in South India continues to be a major public health issue and is strongly associated with antimicrobial resistance. Robust microbiological surveillance is necessary to direct appropriate treatment and preventive strategies. Of particular concern is the emergence and expansion of the highly fluoroquinolone-resistant triple-mutant S. Typhi clone and its ongoing inter- and intra-country transmission in South Asia, which highlights the need for regional coordination of intervention strategies, including vaccination and longer-term strategies such as improvements to support hygiene and sanitation
Implementing and sustaining a mobile medical clinic for prenatal care and sexually transmitted infection prevention in rural Mysore, India
Background In rural India, mobile medical clinics are useful models for delivering health promotion, education, and care. Mobile medical clinics use fewer providers for larger catchment areas compared to traditional clinic models in resource limited settings, which is especially useful in areas with shortages of healthcare providers and a wide geographical distribution of patients.
Methods From 2008 to 2011, we built infrastructure to implement a mobile clinic system to educate rural communities about maternal child health, train community health workers in common safe birthing procedures, and provide comprehensive antenatal care, prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV), and testing for specific infections in a large rural catchment area of pregnant women in rural Mysore. This was done using two mobile clinics and one walk-in clinic. Women were tested for HIV, hepatitis B, syphilis, and bacterial vaginosis along with random blood sugar, urine albumin, and anemia. Sociodemographic information, medical, and obstetric history were collected using interviewer-administered questionnaires in the local language, Kannada. Data were entered in Microsoft Excel and analyzed using Stata SE 14.1.
Results During the program period, nearly 700 community workers and 100 health care providers were trained; educational sessions were delivered to over 15,000 men and women and integrated antenatal care and HIV/sexually transmitted infection testing was offered to 3545 pregnant women. There were 22 (0.6%) cases of HIV, 19 (0.5%) cases of hepatitis B, 2 (0.1%) cases of syphilis, and 250 (7.1%) cases of BV, which were identified and treated. Additionally, 1755 (49.5%) cases of moderate to severe anemia and 154 (4.3%) cases of hypertension were identified and treated among the pregnant women tested.
Conclusions Patient-centered mobile medical clinics are feasible, successful, and acceptable models that can be used to provide quality healthcare to pregnant women in rural and hard-to-reach settings. The high numbers of pregnant women attending mobile medical clinics show that integrated antenatal care with PMTCT services were acceptable and utilized. The program also developed and trained health professionals who continue to remain in those communities
