Theory concerning the high ideality factor of gallium nitride (GaN) based light emitting diode (LED) has been reviewed. The presence of a high ideality factor indicates a large forward voltage that results in efficiency reduction. The paper suggests that tunneling is the main reason defining the exponential behaviour of current-voltage measurements

Getting an accurate prediction of a digital currency, also known as a cryptocurrency price index, becomes a significant factor in helping investors make the right decision. Failure to predict the movement of the crypto market gives a huge impact on profit loss. The difficult part is that market is dynamic in a way that is driven by many factors inc

AIM: To study the association of serum insulin-like growth factor-I (IGF-I) with diabetic retinopathy. ·METHODS: Serum IGF-1 levels were measured in 25 pregnant diabetic patients and 25 pregnant non-diabetic patients who were matched for age, ethnicity, parity and period of gestation. Fundus examination was performed in both groups at 28, 32 and 3

Chitin has proven to have a good mechanical and electrical properties to be used in making piezoelectric thin films. However, due to the restriction in solubilizing chitosan in many solvents, there is increasing interest in exploring the used of chitosan in producing thin films. Chitosan, compared to chitin, can be easily solubilized in certain dil

As many academic institutions adopt web-based learning or online learning to deliver variety of courses, the effectiveness and efficiency of these new technologies are still doubtful. By adopting TAM as research model, this study tends to investigate factors influencing online learning adoption in Universitas Terbuka (UT), Indonesia.. . . .. i AIZR

Muslim scientists have a lot of contributions in many areas such as medical, engineering, pharmaceutical and architectural. Many do not fully appreciate the numerous scientific contributions Islamic civilization and the early Muslims made. From the reality, the Muslim youth generations were raised by Western scientific ideological and not instill t

Purpose: Herbal medicines are the most common type of traditional and complementary medicines (T & CM). T & CM have been used to diagnose and prevent diseases, restore the body’s function, and maintain or improve health. Malaysia has different ethnic groups with different beliefs and cultures. For the three dominant races, Malay, Chinese

Forecasting in the financial sector has proven to be a highly important area of study in the science of Computational Intelligence (CI). Furthermore, the availability of social media platforms contributes to the advancement of SVM re- search and the selection of SVM parameters. Using SVM kernel functions, this study examines the four kernel functio

A novel encapsulated deep eutectic solvent (DES) was introduced for biodiesel production via a two-step process. The DES was encapsulated in medical capsules and were used to reduce the free fatty acid (FFA) content of acidic crude palm oil (ACPO) to the minimum acceptable level (< 1%). The DES was synthesized from methyltriphenylphosphonium br

Microbial biodiesel is converted from microbial lipids via transesterification process. Most microbial biodiesel re-search is focusing on the use of microalgal lipids as feedstock. Apart from the microalgae, lipids can also be ex-tracted from other oleaginous microorganisms like fungi and yeast. However, there are gaps in the studies of lipid produ
