Eczanelerde ilaç üzerinden elde edilen kar, çeşitli mevzuatlar ve yönetmeliklerden dolayı eskiye oranla azalmıştır. Bu durum eczacıları oldukça zor durumda bırakmakta ve gelir- gider arasındaki dengeyi sağlamakta zorlanmaktadırlar. Eczacılar daha çok kar sağlayabilmek ve eczanesini ayakta tutabilmek için OTC ürünleri ve dermokozmetik ürünlerini satmaya yönelip daha çok kar sağlamayı hedeflemektedir. Bu ürünleri daha çok satabilmek ve kâr marjını artırabilmek için çeşitli pazarlama ve kampanya stratejileri eczacılar tarafından uygulanmaktadır. Bu tezde, bu OTC ve dermokozmetik tarzı ürünlerden nasıl en iyi şekilde kâr elde edebileceğimizi, hangi pazarlama ve kampanya stratejilerini uygulayarak daha çok verim sağlayabileceğimiz anlatılmaktadır.

Students in today’s society have become dependent on caffeine in order to perform at their best in multiple facets of their hectic lives, including classes, clubs, and internships. This qualitative-quantitative study focuses on the specific reasons how does different caffeine level in various caffeinated products related to the science academic performance of SHS students of Mina de Oro Catholic School. The study is conducted on 30 students of grade 12 St. Scholastica, randomly distributed to experimental group and control group. It has been found that the two variables have a significant relationship. It has also been found that Cola (t=-0.05; P<0.05), Coffee (t=-0.10; P<0.05) and Chocolate (t=-0.047; P<0.05) make significant differences in the effect of caffeine on science academic performance of Grade 12 students of Mina de Oro Catholic Schools. The results from the study indicate a very low correlation between the science academic performance and caffeine (C8H10N4O2) consumption of grade 12 students of Mina de Oro Catholic School, and different effect of caffeine varies on the caffeine content of a caffeinated products. The study also provides suggestions on possible actions to have a more precise and accurate result of the study.

Kaanga brew is a common illicit liquor from Meru county in Kenya. Popularity of this brew has been growing and is religiously passed down from one generation to the next.

Describe method consist of eco-friendly procedure for the preparation of 2,3-dihydroquinazoline-4(1H)-ones from equimolar 2-aminobenzamide and substituted aromatic aldehydes in presence of 20mol% of silica chloride. Green impact of reaction significantly enhanced due to use of water as solvent and recyclable silica-chloride as catalyst. Good to excellent yield of products, simple working strategy and easy purification are the advantage of present methodology
