guidance\" (p. xii). They have to some extent succeeded in their objectives. Certainly the compilation of references related to aesthetics and visual resources is a valuable contribution in itsell As is evident from this reader’s perspective, however, the poor organization and execution of the book unhappily detract from its effectiveness.

Synthesis and applications of MOF-derived porous nanostructures

The urbanization has significant effects on watershed hydrology and the quality of water in this catchment. One component of water quality is total suspended solids (TSS) which a significant part of physical and degradation and a good indicator of other pollutants on the surface of sediment in suspension. The purpose of this study is to investigate whether turbidity could produce a satisfactory estimate of TSS in urbanizing at the Tasik Kenyir. TSS and Turbidity were analyzed based on in-situ and ex-situ analyses were carried out according to the correlation matrix and linear regression methods at 14 (10–140 m) different depths for two sampling locations in the Tasik Kenyir (which are Chomor River and Mahadir Islandthe name of sampling location in Tasik Kenyir), using data compiled. A log-linear model showed a strong positive correlation between TSS and Turbidity with is (R2 = 0.991 for Chomor River and R2 = 0.995 for Mahadir Island) with a regression equation of ln (TSS) = 1.32 ln (NTU) + C, with C not significantly different. From the result, water quality parameter (TSS and Turbidity) showed outlet significantly which decreased over depth caused the water quality deterioration of Tasik Kenyir development. These results strongly suggest that turbidity is a suitable monitoring parameter where water-quality conditions must be evaluated.

One of the common threats to earth-space communication is the data losss, which is possibly caused by weather factors. In this paper, the effect of solar radiation on radio signal at ultra-high frequency (UHF) band is investigated. The average radio frequencies found at UHF band  were  382.5  MHz,  945.0  MHz,  1800.0  MHz, 1867.5  MHz  and 2137.5  MHz.  The variation of all prominent peaks begins during sunrise and sunset, where all most of the prominent peaks show weak signal strength during the daytime compared during the night time. We can conclude that the radio signals were depending on the presence of solar radiation and the level of solar radiation measured during daytime and night time as solar radiation measured differently as 376.0246 W/m 2  and 428.9846 W/m 2  during 26 th  July and 27 th  July respectively.

Effect of Humidity on Tropospheric Received Signal Strength (RSS) in Ultra-High Frequency (UHF) Band

Sun is constantly produced mass and radiation during its natural activities, which will interact with ionosphere and affect the earth weather In radio astronomer community, CALLISTO is used to capture the radio signal comes from solar activities such as solar burst Solar flares and Coronal Mass Ejections (CMEs) were closely associated with the production of solar radio burst Type II and III However, the determination of solar burst existence is done manually using spectrograph which appears for every 15 minutes  In order to assist the solar radio researcher to speed up the process of solar burst identification and detection, this work presents a new algorithm to auto classify solar radio burst Type II and III The value of frequency drift was used as the main idea in this auto classify algorithm because it can easily implemented using MATLAB There are three main steps involved named as pre-processing, identification and classification Auto calculation of frequency drift burst on spectra was obtained from two parts which are frequency axis (df) and time axis (dt) The results of the frequency drift implementation in classification algorithm show that the algorithm developed gave almost similar determination as in manual detection However, there are always have rooms for improvement for better detection system in future which may include specific characterization of bursts and improved noise elimination

Implementation of Frequency Drift for Identification of Solar Radio Burst Type II

An appropriate site selection for radio astronomy observation is very important in order to find a low level site in RFI value. The aim of this study is to select the best possible factors for astronomical observation sites. There are many factors such as slope, raindrop, river, population density, road network, land used, wireless telephone technology interrupts radio astronomy observation. In this study, we have reported one of the factors that affect radio observation which is rain effect. The site selection study is the most crucial part of decision makers proposes where to build an astronomical observatory, especially in radio astronomy with a maximum efficiency. The observation apparatus was set up to study the effect of rainfall and raindrop to the radio signal. We found that, in the inside observation, we found that spectral lines (Deuterium, Hydrogen, and two Hydroxyl lines) show that the rain gives no effect to radio signal in those windows. We also found that there is very small fluctuate value are very small (about -2 dB) for outside observation. It can be considered has no significant effect on rain below 2.9 GHz.
