As a result, the rise of computationally driven processes has gain popularity in research and shows a great potential to dramatically improve the design process and productivity that evoke innovations in architectural practices wherein computer-based project plays a vital role. However, as these technologies rapidly develop and are increasingly used in practice, there is a realization that substantial organizational and technological barriers exist that inhibit the effective adoption of these technologies in architectural practices wherein complex projects are being handled. Undeniably it happens in small architectural practices whereby resources are very limited. Relevant literature of the subject shows that research in innovations in manufacturing, product design, technology, construction and engineering practices is substantially conducted but re...

Data for water level were obtained from Rufiji Basin Development Authority (RUBADA). The study analyzed trend of water level using time series regression while forecasting of water level in Mtera dam was done using Exponential smoothing. Results revealed that both maximum and minimum water level trends were decreasing. Forecasted values show that daily water level will be below 690 (m.a.s.l) which is the minimum level required for electricity generation on 2023. It was recommended that proper strategies should be taken by responsible authorities to reduce effects that may arise. Strategies my include constructing small dams on upper side of Mtera dam to harvest rain water during rainy season as reserves to be used on dry season. In long run Tanzania Electric Supply Company (TANESCO) should invest into alternative sources of energy.

Mtera dam in Tanzania was taken as a case study. Data for climate variables on four stations were obtained from Tanzania Meteorological Agency (TMA) while data for water level were obtained from Rufiji Basin Development Authority (RUBADA). The study aimed at doing regression analysis on all stations to analyze the impacts of change in climate variables on water level. Results show that rainfall was significant predictor of water level at Iringa and Dodoma while temperature and sunshine were significant at Mbeya station. Change in climate variables accounted for 37% of the fluctuations of water level in the dam. It was recommended that TANESCO should construct small dams on upper side of Mtera dam to harvest rain water during rainy season. In long run TANESCO should invest into alternative sources of energy.

The last five years have witnessed intensive discussions on Knowledge Management and its importance. The aim of this study is to examine the relationship between Knowledge Management and its aspects and its impact on the performance of the governmental institutions in the Emirate of Dubai from the point of view of the managers of these institutions. This study attempts to use the analytical descriptive method to address the subject of the research. In this light, the analytical framework drawn integrates these approaches and can be applied in empirical studies. The study uses the questionnaire in data collection, which is valid and reliable according to the Cronbach’s Alpha value. A Multiple linear regression analysis has been used to predict the OP based on KG, KSR and KST. The findings showed that KG, KSR and KST were the key predictors of OP as these explained 49.6% of the ...

High-density aligned nanowires were obtained on iron foils pre-annealed at 300[Formula: see text]C under a dry air flow for 30[Formula: see text]min. The X-ray diffraction (XRD) patterns indicate that the nanowires are transformed from the small [Formula: see text]-Fe2O3 grains and uniquely grow in the (110) direction. The formation of a high-density of small grains by pre-annealing improved the alignment and density of the [Formula: see text]-Fe2O3 nanowires.

Artemia ingestion rates of E. fuscoguttatus of 36 days and 42 days old larvae were measured in feeding behavior experiments and they were significantly higher with light intensities ≥10 lx compared with feeding rates at ≤ 1 lx. E. fuscoguttatus larvae also exhibited Artemia ingestion rates in the dark or in dim lighting (0-1 lx) that were about 20% of the ingestion rates with ≥ 10 lx.

Dry air flows constantly over the iron foils during the oxidation process in the temperature range of 350–600 °C with annealing periods of 1–6 h. Large quantities of nanoflakes with average tip and bottom diameters of 40 and 140 nm, respectively, and average lengths of 200 nm were obtained at a temperature of 450 °C and 6 h of annealing. These nanoflakes had a preferential growth direction of (110) with a 0.25 nm fringe spacing. Their surface morphology, phase purity, and crystal structures were confirmed by scanning electron microscopy (SEM), X-ray diffraction (XRD), and transmission electron microscopy (TEM) analysis. Good-quality iron oxide nanoflakes can be obtained by optimizing the growth temperature and annealing period. Surface diffusion of iron atoms and iron oxide molecules was believed to be the growth mechanism of the nanoflakes because of the low oxidation temperature used.

A pre-existing renal lesion (PERL) was strongly suspected by his past history of gross macroscopic hematuria and monotrauma to the kidney without other associated injuries. Spiral CT scan with contrast and a retrograde pyelogram (RGP) confirmed an occult complex renal cyst. The gold standard of CT diagnosis in this situation is stressed. Computed tomography is particularly useful in evaluating traumatic injuries to kidneys with preexisting abnormalities. The decision on the initial course of conservative management, ureteral retrograde stenting to drain extravasation, and its final outcome are discussed. Radical nephroureterectomy was carried out by a transperitoneal approach with an early vascular control of the renal pedicle. A brief review of recent literature has been undertaken.

The great role of geometry in Islamic architecture due to restriction of using natural figures is an example. In this research, the application of Islamic geometrical patterns (IGPs), and suitability of their usage over architectural elements in terms of timescale accuracy and architectural-style matching is studied. A detailed survey of hundred wellsurviving buildings throughout the Muslim world of architecture has been conducted for this purpose and as a result, not only origin of patterns identified, but also radical artistic movements throughout the history of Islamic geometric ornaments revealed. Finally, this study sketches the evolution of IGPs through history, while regional diversities are also taken into account.
