Material compatibility with biodiesels and their blends should be verified on a case-by-case basis to ensure long term durability of storage tanks and pipelines. This paper aimed to investigate the degradation of physical properties such as mass, volume, tensile strength, hardness and change in surface morphology for polymers namely polypthalamide (PPA) and polyarylamide (PAA) upon exposure to Pongamia pinnata biodiesel (PPB) and blends. Static immersion tests in B0, B10, B20 and B100 were carried out at 25, 50 and 75 °C for 120, 360 and 720 h to estimate the degradation behaviour of polymers under static condition. Rotating cage was used to study the degradation behaviour at room temperature for 120 h under flow conditions. Significant changes in the physical properties and surface morphology was observed. The overall compatibility sequence of polymers in Pongamia pinnata biodiesel under static condition was found to be PAA > PPA while under flow condition, the order is and PPA > PAA under flow condition.

Oral cancer is one of the common cancers worldwide and in Bangladesh around 7000 cases are diagnosed yearly. It has variable demographics and patient comes to hospital with different presentations. It is mandatory to know the characteristics of the disease so that better awareness and different treatment modalities can be planned. 162 patients with histopathological diagnosis of oral cancer was include in study by consecutive sampling and characteristics of disease was recorded in scientific data collection sheet which was later analyzed by SPSS and result was presented in table, graph and chart form. Incidence of oral cancer is 56.2% in female, in 59.9% cases buccal mucosa is involved in which 90.1% is squamous cell carcinoma. In Conclusion squamous cell carcinoma is most common oral cancer mainly occurs in buccal mucosa of female, in grade I and stage iii majority of patient present in tertiary centers of Dhaka senari.

In Nepal, 47% of individuals who fell ill with TB were not reported to the National TB Program in 2018. Approximately 60% of persons with TB initially seek care in the private sector. From November 2018 to January 2020, we implemented an active case finding intervention in the Parsa and Dhanusha districts targeting private provider facilities. To evaluate the impact of the intervention, we reported on crude intervention results. We further compared case notification during the implementation to baseline and control population (Bara and Siraha) notifications. We screened 203,332 individuals; 11,266 (5.5%) were identified as presumptive for TB and 8077 (71.7%) were tested for TB. Approximately 8% had a TB diagnosis, of whom 383 (56.2%) were bacteriologically confirmed (Bac+). In total, 653 (95.7%) individuals were initiated on treatment at DOTS facilities. For the intervention districts, there was a 17%increase for bacteriologically positive TB and 10% for all forms TB compared to baseline. In comparison, the change in notifications in the control population were 4% for bacteriologically positive, and −2% all forms. Through engagement of private sector facilities, our intervention was able to increase the number of individuals identified with TB by over 10% in the Parsa and Dhanusha districts.
