Published: September 2020

For the Bugis community in the Bugis Karangantu Banten village, death has a rite that is heavily colored by Islamic teachings. This is because death is the transition of human life from the real world to the mysterious realm, and Islam is believed to be a religion that can answer all mysterious problems after death. However, there are still some forms of ritual that appear to be inherited from pre-Islamic traditions. There are two unique rituals from the death rites of the Bugis Muslim community on the coast of Karangantu Banten, which are not found in the death rites of the Muslim community of Banten in general. First, the Mapasili rite which is performed on the 3rd day, and second, the Matampung rite which is generally performed on the 7th or 40th day, or after several months or one year has passed depending on the readiness of funds from the family of the deceased to perform the rite. this is because it costs a lot of money, such as a celebration or wedding ceremony. The Matampung rite is the biggest rite along the death rite for the Bugis people on the Karangantu coast, Banten

An Algorithm Combining Synchronization and Channel Estimation for OFDM Systems
Authors: Lien Pham Hong , Lai Nguyen Duy
Published: September 2020

OFDM (Orthogonal Frequency Division Multiplexing) is more and more popular in applications of digital communications because of the effective spectrum and less impacts  of multipath fading. However, beside these advantages, OFDM signals are destroyed easily by errors such as CFO (Carrier Frequency Offset), SFO (Sampling Clock Frequency Offset). Thus, it’s necessaryto have robustly offset algorithms to overcome these disadvantages. Studies about OFDM we just examined channel estimation with assumptions that synchronization is perfect, and vice versa. However, they have a close relationship, channel estimation can be restricted if synchronization is bad, and vice versa. This paper presents an algorithm combining synchronization and channel estimation in OFDM systems. The algorithm is compared with other proposed algorithms by simulation. The simulation result of the algorithm combining synchronization and channel estimation is close to that of ideal conditions: perfect channel estimation and synchronization.

Published: September 2020

In this study, performance of a lab-scale hybrid up-flow anaerobic sludge blanket (HUASB) reactor treating textile wastewater was evaluated under several operating conditions such as i) textile wastewater mixed up with glucose as food, ii) textile wastewater seeded with sewage sludge and glucose and iii) textile wastewater only. In all cases, two days of incubation period was provided for bacterial growth. In the first case, Klebsiella was the primary Species of bacteria growing in the reactor and the removal efficiency of COD and color was 25% and 56.4% respectively. In the second case, Klebsiella and Escherichia coli were the major bacteria and removal efficiency of COD and color was found to be 38% and 65% respectively. In the last case, Pseudomonas bacterium was dominant in the reactor and removal efficiency of COD, BOD and color was 84%, 93%, and 97% respectively. Wastewater treatment without glucose favored the growth of Pseudomonas which has been found to be effective in degrading organics present in textile wastewater. For all cases, reactor performance decreased after the third or fourth cycle of treatment. However, the removal of sludge after the third cycle allowed a high degradation efficiency of organics to be maintained in the reactor. With proper bacterial growth and maintenance, the HUASB reactor can be a huge upgrade from conventional UASB and a suitable alternative to conventional processes for the treatment of textile wastewater.

Authors: Erhenhi AH
Published: September 2020

Effects of drought and flooding on bean (Phaseolus vulgaris L.) and groundnut (Arachis hypogaea L.) were carried out and compared. Plant growth parameters, biomass content, chlorophyll, ash and soil metal content were studied. The result showed that bean was 21.3cm, 21.8cm and 21.1cm for control, drought and flooding while groundnut recorded 19.9cm, 102.3cm and 18.6cm for control, drought and flooding respectively. Biomass composition recorded little or no variation in fresh weight of stem in bean while groundnut varies from 4.77g – 5.05g accordingly. Leaf recorded highest value of fresh weight to be 6.44g recorded in bean cultivated in drought soil with the least recorded to be 3.61 in the control and flooded soil for groundnut plant. The result of the study showed that drought and flooding had relatively positive effects on the growth properties of bean and groundnut as both plants were able to germinate and grow under both conditions.

Objective: To evaluate and compare the outcome of buccal mucosal graft urethroplasty of unilateral and circumferential urethral mobilization for the management of bulbar urethral stricture.
Methods: Seventy patients having bulbar urethral strictures admitted in the Department of Urology, Dhaka Medical College Hospital, Dhaka between January 2010 to December 2011. Patients were divided into two groups. Group-I, underwent unilateral urethral mobilization, and Group-II, underwent circumferential urethral mobilization for buccal mucosa graft urethroplasty. All patients were followed up at least six months. The statistics used to analyze the data were descriptive statistics, and p value <0.05 was considered as significant.
Results: Mean±SD of age in Group-II and Group-I were 41.1±9.2 and 37.4±8.2 years respectively. All the baseline findings were identically distributed between the groups. Comparison of outcome at month 3 showed that peak urinary flow rate increased from their baseline figures, but the increase was significantly more in the unilateral group than that in the circumferential group (21.2±1.2 vs. 18.9±2.0 Qmax, p =< 0.001). After 6 months, evaluation showed that the peak urinary flow rate significantly higher in Group-I, than that in Group-II, (24.2±2.9 vs. 21.9 ± 3.3, p < 0.001). The voided urine volume was also significantly higher in Group-I, than that in Group-II (330.8±50.1 vs. 294.5±46.1 ml, p = 0.004). Consequently, PVR was lower in the former group than that in the latter group (11.6±3.3 vs. 14.1±2.9 ml, p = 0.002). Complications in unilateral urethral mobilization had a significantly lower (20%) than that of circumferential urethral mobilization(45.71%) (p=0.024).
Conclusion: Buccal mucosa grafting is a versatile and effective treatment for the anterior urethral stricture, and the outcome is excellent following unilateral urethral mobilization in experienced hands.

Published: September 2020

Objective: To determine the short term outcome of anastomotic urethroplasty.
Material and Methods: From January 2013 to June 2015, 25 male patients underwent anastomotic urethroplasty at our center and were analyzed prospectively. Mean age was 28.1 years (range 13-50), average stricture length was 2.5 cm (range 1.5-2.5). Patients with post-prostatectomy stricture, stricture more than 2.5 cm in length or patients of stricture with neurogenic bladder and patients with any perineal disease were excluded from the study. Retrograde urethrogram and voiding cysto-urethrogram was done in every patient to assess stricture length and location. Stricture excision and end-to-end anastomosis of urethra with spatulation was performed in every patient. Minimum followup period was 6 months and maximum 30 months. All patients had obliterative stricture.
Results: The mean operative time was 105 min (range 90-120). Four patients (16%) developed complications postoperatively. Wound infection occurred in 01 (04%) patient. Stricture recurrence found in 02 (08%) patients and erectile dysfunction in 01 (04%) patients. Twenty one patients (84%) had excellent outcome, Two (08%) needed optical internal urethrotomy and of them one (04%) failed to respond.
Conclusion: Anastomotic urethroplasty has a high success rate of 92%. It is technically straightforward with minimal morbidity. Long term follow-up is strongly recommended for ultimate success.

Congenital Megalourethra Associated With Urethral Duplication: A Case Report
Authors: Kabir Muhammad Humayun , Ahmed Tanvir , Islam Md Saiful , Ali SM Yunus , Islam Md Rafiqul
Published: September 2020

A 28 years old male with well developed secondary sexual characteristics was admitted in BSMMU with a grossly swollen, malformed phallus and passage of urine mostly through an opening in the perineum. After birth, his parents noticed that when the baby micturates the phallus is swollen and few drops of urine comes out through the external urethral meatus but most of the urine comes out through an opening in the perineum. No treatment was taken by his parents for this complaint. At puberty his secondary sexual characteristics developed normally. He felt sexual urge towards females but his penis was not erected. At the peak of his sexual excitement, orgasm occurs with release of whitish seminal fluid which comes mostly through perineal opening. His general physical examination was unremarkable & examination of the genitalia revealed well developed scrotum. Both of the testes were normal in size, shape and consistency but the penile shaft was large and flabby, and the ventral aspect of the penis appeared as a sac with mild pseudo phimosis. Careful palpation suggested the absence of the corpus spongiosum & corpora cavernosa. Both these findings were subsequently confirmed by a duplex colour doppler study. The penis distended ventrally when he tried to micturate and the urinary stream was narrow. About 75% of urine flow evacuates through perineal opening which was located about 2 cm from anal opening in the midline ventrally. A voiding cystourethrogram revealed that whole of the anterior urethra was grossly dilated with narrowing at the bulbar part & external urerthral meatus. There was another passage (about 5 cm) from the scrotal margin up to proximal posterior urethra. Cystogram showed a bladder diverticulum at left lateral wall. An urethrocystoscopic examination revealed that just proximal to the stenosed external urethral meatus the urethra is widely dilated which seemed like a transparent fusiform sac with irrigating fluid. Whole of the anterior urethra was very thin walled with transmitting lights through it. Proximal part of the urethra near the external sphincter was grossly narrowed. Urethrocystoscope was also introduced through the abnormal urethral opening into the perineum which was located in the midline raphe of the perineal region about 2 cm from the anal verge. This urethra joined with the penile urethra distal to the external sphincter. Prostatic part of the common urethral channel was normal containing verrumontanum and a normal bladder neck.
