Effect Of Light

Lighting is one of the key elements in any space and building infrastructure. Good design for an area in the building requires sufficient light that contributes to the efficiency of the activities. The correct method allows natural light to transmit, reduce heat and glare in providing a conducive learning environment. Light plays a significant influence to the quality of space and contributes focus of the students in an architecture studio. Previous research has shown that the effect of light also controlled emotions, behavior, and mood of the students. The operations of artificial lighting that have been used most of the time in an architecture studio during day and night may create lavishness and inadequacy at the same time. Therefore, this paper focuses on the identifying the quality of light for the architecture studio in UiTM (Perak), to instill a creative learning environment. Several methodologies adopted in this study such as illuminance level measurement using lux meter (LM-8100), and a questionnaire survey in gauging the lighting comfort level from students’ perspective. The study revealed that the illuminance level in the architecture studio is insufficient and not in the acceptable range stated in the Malaysian: Standards 1525:2007 and  not evenly distributed.  The study also concluded that the current studio environment is not condusive and appears monotonous.

Subject. The article reviews the way strategic threats to energy security influence the quality of people's life. Objectives. The study unfolds the theory of analyzing strategic threats to energy security by covering the matter of quality of people's life. Methods. To analyze the way strategic threats to energy security spread across cross-sectoral commodity and production chains and influences quality of people's living, I applied the factor analysis and general scientific methods of analysis and synthesis. Results. I suggest interpreting strategic threats to energy security as risks of people's quality of life due to a reduction in the volume of energy supply. I identified mechanisms reflecting how the fuel and energy complex and its development influence the quality of people's life. The article sets out the method to assess such quality-of-life risks arising from strategic threats to energy security. Conclusions and Relevance. In the current geopolitical situation, strategic threats to energy security cause long-standing adverse consequences for the quality of people's life. If strategic threats to energy security are further construed as risk of quality of people's life, this will facilitate the preparation and performance of a more effective governmental policy on energy, which will subsequently raise the economic well-being of people.

Formulation Variables

The matrix tablets of cinnarizine and nimodipine were prepared with varying ratio of Carbopol- 971P and co-excipients of varying hydrophilicity (i.e. dicalcium phosphate and spray dried lactose) by direct compression and wet granulation using alcoholic mucilage. The prepared tablets were evaluated for weight variation, hardness and friability. The influence of concentration of the matrix forming material and co-excipients on the release rate of the drug was studied. The release rate of Cinnarizine (more soluble drug) from tablets followed diffusion controlled mechanism whereas for nimodipine (less soluble drug), the drug release followed case-II or super case- II transport mechanism based on Korsmeyer- Peppas equation. The results indicated that the drug release from matrix tablets was increases with increase in hydrophilicity of drug and co-excipients. The release of drug also increased with thermal treatment and decreasing polymer concentration.

The quality of the software can be measured by its return on investment. Factors which may affect the return on investment (ROI) is the tangible factors (such as the cost) dan intangible factors (such as the impact of software to the users or stakeholder). The factor of the software itself are assessed through reviewing, testing, process audit, and performance of software. This paper discusses the consideration of return on investment (ROI) assessment criteria derived from the software and its users. These criteria indicate that the approach may support a rational consideration of all relevant criteria when evaluating software, and shows examples of actual return on investment models. Conducted an analysis of the assessment criteria that affect the return on investment if these criteria have a disproportionate effort that resulted in a return on investment of a software decreased.

The aim of present work was to develop once daily sustained release matrix tablet of aceclofenac by wet granulation technique using natural gums i.e.: gum acacia, guar gum and Xanthan gum. In this present study matrix tablets were prepared using three different methods and a comparative study was done. Aceclofenac sodium being the newer derivative of diclofenac having short biological half life (4hrs.), so it requires more than one dose per day to maintain therapeutic dose. The prepared tablets were evaluated for various parameters like weight variation, hardness, swelling index, friability, percent drug release and various release profile like zero order, first order, Higuchi's, and Koshemeyrs-peppa. All the evaluation parameters met pharmacopoeial specifications and through dissolution studies it was matrix tablets prepared with method 2 shows heighest percent drug release and matrix tablet prepared by method 3 showed lowest percent drug release at the end of 8 hrs. (Shown in fig. 8, comparative release study of all three formulations). Matrix tablet of aceclofenac were successfully prepared and evaluated and it can be concluded that matrix tablet prepared with natural gums showed release rate for a prolonged time and can be of great importance for “once daily” tablet to reduce side effects and toxicity related with NSAIDs.

The purpose of this study was to evaluate the potential of polymers for masking the taste of bitter drugs when incorporated into orally disintegrating tablets. The tablets were produced by simple wet granulation technique with a model compound (baclofen) which is moderately bitter. The formulating procedure had two variables to obtain good taste masking with desirable characteristics. The optimal granulation process parameters were polymer selection and its concentration (w/w), suitable for pilot scale level. Dextrates, β- cyclodextrin, eudragit EPO and PVP K-30 were used in preparation of granules by using water and iso-propyl alcohol. Crospovidone was used intra and extra granularly as superdisintegrant.  Sodium bicarbonate and citric acid were used as effervescent for fast disintegration of tablets, which also optionally act as desensitizer of taste buds. Results from evaluation of tablets indicated a disintegration time (avg) of 30-35 sec and 100% drug release was achieved within 5 min. But taste masking was achieved by only with eudragit EPO. Results from an evaluation by a panel of six human volunteers demonstrated that the orally disintegrating tablets which are prepared by using polymer Eudragit EPO (5% and 7.5% w/w of tablet) and PVP (7.5% w/w of tablet) improved taste, significantly. On studying physical parameters, F9 formulation demonstrated acceptable level of hardness and friability with good taste masking and it was thus considered as an optimized formulation
