Pulverized PharmXS (0.7003) was dissolved in 5mL of dichloromethane in a 125 mL Erlenmeyer flask. Vacuum filtration was performed to give white power like sucrose (0.0977g). The dichloromethane filtrate was extracted twice with two separate 5 mL portions of 10% sodium carbonate solution, and about 8 drops of 6M hydrochloric chloride were added to the combined aqueous extracts to bring to PH to 2. The aqueous extracts were then vacuum filtered to give aspirin (0.0431g). About a gram of granular...
For implementing an optical free-space transmission system at data rates up to 10 Gbit/s, commercially available devices developed for terrestrial fiber optic applications may be employed to advantage. We designed, set up and tested a breadboard consisting of an NRZ/RZ transmitter with a booster amplifier of 1 Watt optical output power and an optically preamplified direct detection receiver. The main objective was to determine the receiver sensitivity and assess critical components. With the...
As demonstrated in (Table 1.)the experimental haematological index of rat is greater than both the standard human male and human female haematological indices, 6.25 x 1012 erythrocytes per litre. The RCC gives the oxygen carrying capacity of the blood. The higher the RCC, is the greater the oxygen carrying capacity of blood. This higher capacity is a requirement for rats as they are highly active organisms, and therefore their cells have a high rate of metabolism. Hence the haematological...
INTRODUCTION Eurycoma Longifolia, also locally known as Tongkat Ali, is a popular herbal remedy that is frequently prescribed as a single ingredient or as a mixture with other herbs. The decoction from the Tongkat Ali roots are used as folk medicine for the treatment of aches, persistent fever, malaria, erectile dysfunction (Perry, 1980), dysentery, glandular swelling (Darise et al., 1982; Darise et al., 1983; Lin et al., 2001) and as health supplements. In addition, the crude extracts of this...
4. DiscussionA link between hymenopteran vision and Australian floral colouration. In part 1, this project aimed to investigate a link between hymenopteran vision and Australian floral colouration. My results suggest that the receptors of bees are well placed to allow for optimal evaluation of steps in the floral spectra of Australian flowers. As bee vision predates the evolution of flower colours (Chittka 1996), this strongly suggests that many Australian native plants have evolved colours to...
From Figure 4.8 it is understood that increase in dye and NaCl concentrations led into a decrease in dye removal from the aqueous solution. A maximum decolouration of 89.0 % was achieved at 10 mg/l RR 158 treated with 1.0 mol/dm3 while 44.3% of 50 mg/l of dye was removed using 2.0 mol/dm3 NaCl. The peak at 1.0 mol/dm3 implies that maximum degradation occurred at that particular concentration, thus confirming the statement made in section 4.7.1. Both the presence of too much dye molecules and...
The strategy outlined below is aimed at identifying high-confidence binding sites of Cdx2 in TS cells by utilizing position and fold-enrichment data calculated from the ChIP-seq data set along with expression dynamics in TS cells versus differentiated TS cells and TS cells versus ES cells. The present status quo for ChIP-seq analysis is to identify all significant binding sites above background, in my view this normally generates a mind-numbingly large list of purported target genes most of...
Are temporal transcription factors fundamentally different to transcription factors that pattern spatial events? Recent studies have tried to answer important questions of what distinguishes the embryonic spatial roles and temporal roles of transcription factors such as hunchback and kruppel. Some researchers now believe that there could be genetic interactions between the spatial and temporal roles that have been conserved over time. Hunchback has long been known for its essential role in...
A combination process has developed as a pretreatment of non biodegradable leachate. The processes consist of air stripping coupled with agitation as a modified of ammonia stripping followed by coagulation-flocculation processes. The main aims of these processes are reducing a concentration of NH3-N and organic matter as well as enhancing the biodegradability of landfill leachate. Ammonia stripped by the airflow rate of 10 L min-1 at pH 11 for 3 h, while the agitation process applied to air...
Fibers are generally complex carbohydrates that are mostly found in outer layer of plants. Although it is already in a part of human diet , it has been recently considered as a dietary constituent.( Nelson, 2001) It was firstly described as a plant cell wall in 1953 and later on in 1973 the definition was expanded with "indigestible polysaccharides and lignin" terms (Kamp, 2004) Recently , The American Association of Cereal Chemists (AACC) updated its definition as following; "...
