SELF-DUAL CODES OVER THE RING F2m + uF2m + vF2m + uvF2m
Ankur 장전수학회 2018 Proceedings of the Jangjeon mathematical society Vol.21 No.4
We discuss self-dual codes over the ring R = F2m +uF2m + vF2m + uvF2m, u² = 0, v² = 0, uv = vu. We consider denition of trace function and self-dual basis over the field F2m. We consider the Gray map and self-orthogonal basis to discuss some theoretical properties of self-dual and Type II codes over the ring R. Also we see how Lee weight and trace are related over the ring R for a self-dual basis.

Purpose: This study was performed to characterise the nature, clinical presentation, mode of insertion, and management of intravesical foreign bodies in patients treated at our hospital. Methods: Between January 2008 and December 2014, 49 patients were treated for intravesical foreign bodies at King George Medical University, Lucknow. All records of these patients were retrospectively analysed to characterise the nature of the foreign body, each patient’s clinical presentation, the mode of insertion, and how the case was managed. Results: A total of 49 foreign bodies were retrieved from patients’ urinary bladders during the study period. The patients ranged in age from 11 to 68 years. Thirty-three patients presented with complaints of haematuria (67.3%), 29 complained of frequency of urination and dysuria (59.1%), and 5 patients reported pelvic pain (10.2%). The circumstances of insertion were iatrogenic in 20 cases (40.8%), self-insertion in 17 cases (34.6%), sexual abuse in 4 cases (8.1%), migration from another organ in 4 cases (8.1%), and assault in 4 cases (8.1%). Of the foreign bodies, 33 (67.3%) were retrieved by cystoscopy, while transurethral cystolitholapaxy was required in 10 patients (20.4%), percutaneous suprapubic cystolitholapaxy was performed in 4 patients (8.1%), and holmium laser lithotripsy was performed in 2 patients (4.08%). Conclusions: Foreign bodies should always be included in the differential diagnosis when evaluating a patient who presents with chronic lower urinary tract symptoms. A large percentage of foreign bodies can be retrieved using endoscopic techniques. Open surgical removal may be performed in cases where endoscopic techniques are unsuitable or have failed.

This paper presents the comparison and performance analysis for CPL and CMOS based designs. We have developed the Verilog-HDL codes for the proposed designs and simulated them using ModelSim for verifying the logical correctness and the timing properties of the proposed designs. The proposed designs are then analyzed at the layout level using LASI. The layouts of the proposed designs are simulated in Winspice for timing and power characteristics. The result shows that the new circuits presented consistently consume less power than the conventional design of the same circuits. It can also be seen that these circuits have the lesser propagation delay and thus higher speed than the conventional designs.

A continuous bio column reactor was designed for the simultaneous bioaccumulation of Cr(VI) and biodegradation of phenol from their binary synthetic solution with the ratio of (2 : 1). Consortium culture of Bacillus sp. and Escherichia coli was immobilized onto tea waste biomass in the packed bed column. The metabolites formed during the biodegradation of phenol by Bacillus sp. were utilized by Escherichia coli for the bioaccumulation of Cr(VI). The considerable effect of empty bed contact time (EBCT), bed height (cm) and flow rate (mL/min) was investigated onto the simultaneous removal of Cr(VI) and phenol in the column reactor. However, after 3-4 days of continuous treatment of Cr(VI) and phenol the effect of these process parameters was not significant. Dissolved oxygen (DO) of effluent has been found to decrease with run time of packed bed column. The pH of the effluent decreased initially for 2 days but after that it became the same as the influent. A mass transfer study was carried out to calculate the pseudofirst- order rate constant for Cr(VI) and phenol, which was in good agreement with experimental results.

The present study was conducted to evaluate the genetic variability and correlation of different characters associated with grain yield in wheat. Forty genotypes were grown in randomized block design with three replications and evaluated for twelve yield and yield-related characters. Highly significant differences and adequate genetic variability were observed among the genotypes for all twelve characters. The heritability showed highest value for plant height, days to 50% flowering, days to maturity, peduncle length, 100 grain weight, number of spikelet per spike and number of grains per spikelet. Highest values of genetic advance were obtained in biological yield, plant height, days to maturity, peduncle length and days to 50% flowering. Correlation studies revealed an intensive selection for number of tillers, days to 50% flowering, days to maturity, number of spikelet per spike, number of grains per spikelet and 100 grain weight will contribute to improve the seed yield in wheat. Path analysis showed that maximum direct effect on grain yield per plant was contributed mostly by biological yield, followed by harvest index, spike length, plant height and days to 50% flowering. Principal components analysis (PCA) was performed and the first five principal components explained 75% of the observed variation. PC1 accounted for 23% of variation and showed the largest loading values for number of tiller`s per plant, biological yield and grain yield per plant. PC2 accounted for 17% and associated with plant height, peduncle length and harvest index. PC3 accounted for 13% and related to the days to 50% flowering and days to maturity. PCA analysis showed that wheat genotypes HPB42, UP2123, PBW527 and HD3024 showed good performance among wheat genotypes on the basis of all traits combined. The identified genotypes may be useful for wheat yield improvement.
