An analytic Study of the Key Factors Influencing the Design and Routing Techniques of a Wireless Sensor Network

A wireless sensor network contains various nodes having certain sensing, processing & communication capabilities. Actually they are multifunctional battery operated nodes called motes. These motes are small in size & battery constrained. They are operated by a power source. A wireless sensor network consists of a huge number of tiny sensor nodes which are deployed either randomly or according to some predefined distribution. The sensors nodes in a sensor network are cooperative among themselves having self-organizing ability. This ensures that a wireless network serves a wide variety of applications. Few of them are weather monitoring, health, security & military etc. As their applications are wide, this requires that sensors in a sensor network must play their role very efficiently. But, as discussed above, the sensor nodes have energy limitation. This limitation leads failure of nodes after certain round of communication. So, a sensor network suffers with sensors having energy limitations. Beside this, sensor nodes in a sensor network must fulfill connectivity & coverage requirements. In this paper, we have discussed various issues affecting the design of a wireless sensor network. This provides the readers various research issues in designing a wireless sensor network

A study to compare the diagnostic accuracy of GeneXpert MTB/RIF/assay and its comparison with liquid culture in clinically suspected cases of genital tuberculosis attending outpatient department of tertiary center

Background: Tuberculosis is a major health issue globally despite a declining trend in mortality with effective diagnosis and treatment, an estimated 10.4 million persons developing active TB each year with 1.33 million deaths. Objective of this study was to evaluate role of GeneXpert MTB/RIF/assay in diagnosis of female genital tuberculosis in suspected cases of tuberculosis.Methods: It was a cross sectional study done in department of obstetrics and gynecology in S. N. Medical college Agra for a period of 2 year (July 2017 to October 2019). 70 cases were selected from OPD of department of obstetrics and gynecology, S. N. Medical College Agra who met the inclusion and exclusion criteria after taking proper consent. In all selected cases endometrial biopsy sample was taken using endometrial biopsy curette in premenstrual period. All samples of endometrial biopsy were taken under all aseptic precaution from both corneal ends, anterior and posterior wall and lower part of uterus using endometrial biopsy curette and sample was collected in two separate sterile vials having normal saline and was sent for GeneXpert MTB/RIF/assay and liquid culture simultaneously.Results: Out of total 70 clinically suspected cases of female genital tuberculosis in between 20-45 years of age cough with expectoration 94% was the most common respiratory symptom followed by fever 81%, weight loss 56% and anorexia 54%. Prevalence of genital tuberculosis in active pulmonary tuberculosis patients was 30%. Irregular menstruation, vaginal discharge and pelvic pain were present in 69%, 60% and 52% patients respectively.Conclusions: The overall sensitivity of CBNAAT was 22% and specificity was 77%. The overall sensitivity of liquid culture was 28% and specificity was 71%

Urinary tract infection caused by Myroides spp. in diabetic patients: To be or not to be

Myroides is a non-fermentative, Gram-negative rod-like bacteria. It is a rare opportunistic pathogen which has been reported to cause many serious infections. Management of infections caused by Myroides can be challenging due to its high resistance to most antibiotics. We report three cases of urinary tract infection (UTI) due to Myroides species in patients with diabetes mellitus Type II. Myroides spp. isolated were resistant to all the antibiotics tested: Amoxicillin-clavulanic acid, piperacillin-tazobactam, cefepime, ceftriaxone-cefoperazone sulbactam, amikacin, gentamicin, imipenem, meropenem, ciprofloxacin, colistin, tigecycline, and co-trimoxazole. Two strains were sensitive to minocycline (minimum inhibitory concentration <1 μg/mL). Two patients had Foley’s catheter in place and one patient had urinary retention at the time of diagnosis. The infection in two cases was nosocomial, whereas one case appeared to have a community-acquired infection with Myroides. Clinicians should consider the possibility of Myroides as a pathogen in UTI in diabetic patients, especially in nosocomial settings

Biomimetic synthesis and ultrastructural characterization of a zerovalent gold-hydroxyapatite composite

This manuscript describes one-pot, in situ synthesis of organoapatite-gold nanoparticle composite and its characterization by XRD, energy dispersive X-ray analysis, atomic force, and scanning electron microscopy. This methodology offers a different approach into the synthesis of zerovalent metal-mineral-phase nanocomposites having potential application as osteointegrative ceramics

FINGERPRINT DETECTION AND RECOGNIZATION TECHNIQUES USING GABOR FILTER

Fingerprints are most extensively and effectively appropriate for the proof of identity in present days. Mostly because of their uniqueness among the people, public acceptance, originality, stability through life, and their least risk of invasion. Fingerprint technology, which is basically a biometric system, is utilized to identify an individual based on their physical qualities. Fingerprint matching is the trendiest biometric method appropriate to provide authentication. Fingerprint verification is one of the most trustable biometric security system in the world of computers. In this paper we proposed fingerprint algorithm which uses Gabor filter to capture local and global minute details in a fingerprint. The matching is based Euclidean distance between input image to test compared to trained fingerprints images. We are able to detect fingerprint with marginally best results. Our fingerprint framework performs best as compared to any other techniques

Phosphodiester modification by zinc metalated adenine polymer with carboxyl pendants

This report describes a novel carboxyl pendant containing adenylated polymeric template, its metalation with Zn (II), and manifestation of catalytic activity for the hydrolysis of model phosphodiester, bis(p-nitrophenyl) phosphate (bNPP), and plasmid cleavage. Observation of a bell-shaped pH-K<SUB>obs</SUB> profile suggested influence of pH variation over hydrolysis rate. This metalated polymer also afforded facile relaxation of pBR322 supercoiled DNA, with an interesting reusability feature intricately associated with heterogeneous catalysis

Granulomatous hepatitis by Nocardia species: An unusual case

A case of granulomatous hepatitis due to Nocardia is reported here. The case patient was a 63-year-old immunocompetent man who presented with persistent fever, weight loss, and malaise. Radiology suggested an enlarged liver with dense diffuse to multiple tiny micronodular areas of parenchymal involvement, possibly granulomatous. Liver biopsy showed necrotizing granulomas and anti-tuberculosis therapy was initiated, but the patient showed no improvement. A repeat liver biopsy showed similar histopathology; however PCR for Mycobacterium tuberculosis was negative, while MGIT 960 culture grew filamentous Gram-positive bacilli, acid-fast by 1% H2SO4, identified biochemically as Nocardia spp. 16S rRNA sequencing confirmed Nocardia spp. A diagnosis of granulomatous hepatitis due to Nocardia spp. was made. Treatment based on drug sensitivity testing was initiated, resulting in a resolution of symptoms. The patient’s history revealed that stray dogs adopted by his family had skin lesions, likely canine distemper (two newborn puppies had died recently). Nocardia is known to co-infect animals with distemper. This could have been the possible source of a zoonotic infection to the case patient. Nocardia spp. are seldom reported from sites other than the lungs, skin, or brain; the current case highlights the involvement of the liver. Due to the granulomatous tissue response, it could represent a differential diagnosis of tuberculosis in such cases.
