ON DOMINATION IN ZERO-DIVISOR GRAPHS OF RINGS WITH INVOLUTION
Nazim, Mohd,Nisar, Junaid,Rehman, Nadeem ur Korean Mathematical Society 2021 대한수학회보 Vol.58 No.6
In this paper, we study domination in the zero-divisor graph of a *-ring. We first determine the domination number, the total domination number, and the connected domination number for the zero-divisor graph of the product of two *-rings with componentwise involution. Then, we study domination in the zero-divisor graph of a Rickart *-ring and relate it with the clique of the zero-divisor graph of a Rickart *-ring.

Introduction: Buthūr Labaniyya (Acne vulgaris) is a multifactorial disorder of the pilosebaceous units characterized by non-inflammatory and inflammatory clinical lesions. Several Unani medications have been used for centuries to treat acne. Objectives: Evaluation of safety and efficacy of Tila-i Muhāsā in patients with acne vulgaris Materials and Methods: This clinical study was conducted in patients with acne vulgaris. Patients applied Tila-i Muhāsā or 5% Benzoyl Peroxide (BPO) once daily for 6 weeks. Assessment of efficacy was carried out by Global Acne Grading System (GAGS) and Patient Global Assessment (PGA) scores. In addition, overall severity of acne was evaluated on a 5-point Cook's acne grading scale using photographic standards. Assessment of safety was performed through adverse drug reactions, local dermal tolerability, vital signs, and routine laboratory investigations. Results: A total of 60 patients (30 in each group) completed 6 weeks of treatment. The mean percentage reduction in GAGS score at 6 weeks from baseline in Unani group (66.97%) and BPO group (59.09%) was statistically significant (P<0.0001). After 6 weeks of therapy, the mean percentage reduction in PGA score compared to baseline in Unani group (57.44%) and BPO group (50.23%) was statistically significant (P<0.0001). No serious adverse events were reported in both groups; however, mild adverse events occurred more frequently in BPO group (30%) compared to Unani group (10%). Conclusion: Tila-i Muhāsā was found to be effective and safe in the treatment of acne vulgaris. However, further clinical studies with larger sample size and longer duration of therapy need to be conducted.

Hemorrhoidal disease is one of the most common gastrointestinal ailments affecting life quality of the patients. Unani classical literature is replete with anti-hemorrhoidal drugs, but scientific evidence is lacking. Therefore, Safūf Zāj (powdered alum) and Marham-e-Māzū (gall ointment) having potent anti-hemorrhoidal actions were selected to evaluate their efficacy in hemorrhoids. This clinical trial was conducted on 30 participants with hemorrhoids, aged > 18 years. All the participants received Safūf Zāj for sitz baths and Marham-e-Māzū to be applied twice daily for 2 weeks. Primary outcome measures were: change in pain intensity, anal itching, and defecate discomfort assessed on 100 mm VAS scale and per-rectal bleeding assessed on 4-point scale. Secondary outcome measures were: change in the size of the external hemorrhoidal mass assessed on 5-point scale, grade of internal hemorrhoid assessed by Goligher classification and quality of life (QoL) assessed on SF-12 questionnaire. The per-protocol analysis was done on 30 participants and statistically significant improvement was seen in primary and secondary outcome measures. Moreover, both the mental and psychological components of QoL were improved. The study inferred that therapeutic approach of Safūf Zāj and Marham-e-Mazu is safe and efficacious in hemorrhoids. Future studies with well-designed RCTs are highly recommended.
Suitability of Palm Based Oil as Dielectric Insulating Fluid in Transformers
Norhafiz Azis,Jasronita Jasni,Mohd Zainal Abidin Ab Kadir,Mohd Nazim Mohtar 대한전기학회 2014 Journal of Electrical Engineering & Technology Vol.9 No.2
Mineral oil has been widely used as dielectric insulating fluid in transformers due to its excellent performance in-service. However, there are few issues with mineral oil such as it has poor biodegradability and could contaminate the environment if a spillage occurs. With the increasing tight regulation on safety and environment, alternative fluids for mineral oil are currently being investigated and among the suitable candidate is the vegetable oil. There are different types of vegetable oils and one of them is the palm based oil. At the moment, extensive research works are carried out to examine its feasibility to be applied in transformers. This paper will review the previous research works that were carried out to examine the suitability of palm based oil as dielectric insulating fluid in transformers. The physical and chemical properties of palm based oil are studied based on viscosity, acidity, oxidation stability and flash point. Next, the electrical characteristics of palm based oil are examined based on AC breakdown voltage, relative permittivity, dissipation factor and partial discharge.
