“…From Figure 9 Smoke emission for Diesel, P30K70, P50K50 and P70K30 are 79.9% opa, 90.1% opa, 84.9% opa, and 76.6% opa respectively. Even though Pine oil has a low cetane number, in contrast, its low viscosity and high volatility support fast oxidation and reduce smoke emissions, as stated by Venkatesan Rajasekar et al 49 …”

This article studied the effect of blending low‐viscous Pinus oil with high‐viscous Millettia Pinnata oil on CI engine characteristics. The three blends of a combination of Pinus oil and Millettia Pinnata oil (P70K30, P50K50, and P30K70) were tested in a single‐cylinder water‐cooled computerized diesel engine coupled with an eddy current dynamometer by varying the load from 0% to 100%. The performance result establishes a positive correlation between BTE and the amount of Pinus oil in the blended fuel. Among the tested biofuel samples, P70K30 has the highest brake thermal efficiency of 29.73% but is 4.8% lower than diesel. At full load, the BSFC and BSEC of P70K30 show a 7.4% and 8.6% drop compared to diesel fuel but are higher than P50K50 and P30K70. Among the tested biofuel samples, a maximum in‐cylinder pressure of 70.96 bar was observed for P70K30, which is higher than P50K50 and P30K70 but lower than diesel. The net heat release rate and rate of pressure rise were found to be 48.26 J/oCA and 5.57 bar/oCA for P70K30, the highest among all tested conditions. Cycle‐to‐cycle variations were studied by calculating the standard deviation, range, and coefficient of variation for the in‐cylinder peak pressure of 100 cycles. The P70K30 has a coefficient of variation of 1.24%, which is higher than the P50K50 and P30K70 but lower than diesel. The P‐v diagram concludes that the three tested biofuels have strong thermodynamic properties since they have a good expansion rate and a pattern similar to diesel fuel. The emissions results show that increasing the amount of Pinus oil in blended fuel increases the NOx to 1410 ppm emissions and decreases the CO to 0.18%, HC to 44 ppm, and smoke to 76.6%.

“…15,31,[40][41][42] A remarkably high CO peak was observed with B30 at 20 C. In this case, the effect of higher oxygen content in the molecules of biodiesel seems to be masked by the effect of higher viscosity of biodiesel blends, which resulted in poor atomization of the fuel leading to an increase in CO peak during cold start. 43,44 Nevertheless, most of CO peaks emitted by the engine using palm biodiesel blends during cold starting were below 0.01 ppm, which were considered to be very low except B10 and B30 at 10 and 20 C, respectively.…”

Palm biodiesel fuel is limited to 7% (v/v), that is, B7 in petroleum diesel used at Malaysian highlands due to concerns over poor flow characteristics. This article investigated the cold start performance of a common rail direct injection turbocharged diesel engine using B7, B10, B20, and B30 blends in a simulated cold climatic chamber at 5, 10, 15, and 20 C. All the blends passed the startability test at 20 C but failed at 5 C. Higher biodiesel blend of B20 could withstand moderate cold temperature (15 C) without startability issue, while B7 and B10 were usable beyond 15 C. Engine workability after start-up was insignificantly affected though, on average, 23% increase and 56% reduction observed in engine starting time and speed stability between B7 (standard) and other blends. Emissions of CO was noticeable, <0.1%, while CO 2 and NOx were reduced by 13% and 18%, respectively during cold start-up using B10 and B20. It is expected that B20 could be destined for at the Malaysian highlands with the coldest temperature not exceeding 15 C threshold for more than 5 h. Considering the importance of cold filter plugging point, it is suggested for inclusion in existing diesel standards to minimize issues while deploying high biodiesel blends at highlands commercially.

“…Among the various risk factors related to the occurrence and development of cancer, APA is an important endogenous factor directly triggering malignant phenotypes. Specific APA events are closely related to the occurrence of malignant tumors and autoimmune diseases ( Rajasekar et al, 2020 ). For example, high levels APA in cancer cells are often accompanied by loss of 3′-UTR inhibitory elements, indicating that APA plays a universal role in oncogene activation ( Gruber and Zavolan, 2019 ).…”

Roles of Major RNA Adenosine Modifications in Head and Neck Squamous Cell Carcinoma

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer malignancy worldwide and is known to have poor prognosis. The pathogenesis behind the development of HNSCC is not fully understood. Modifications on RNA are involved in many pathophysiological processes, such as tumor development and inflammation. Adenosine-related RNA modifications have shown to be linked to cancer and may play a role in cancer occurrence and development. To date, there are at least 170 different chemical RNA modifications that modify coding and non-coding RNAs (ncRNAs). These modifications affect RNA stability and transcription efficiency. In this review, we focus on the current understanding of the four major RNA adenosine modifications (N6-Methyladenosine, N1-Methyladenosine, Alternative Polyadenylation Modification and A-to-I RNA editing) and their potential molecular mechanisms related to HNSCC development and progression. We also touch on how these RNA modifications affect treatment of HNSCCs.
