In attempting to use the SEM to investigate the transition from the vegetative to the floral state in oat (Avena sativa L.) it was discovered that the procedures of fixation and critical point drying (CPD), and fresh tissue examination of the specimens gave unsatisfactory results. In most cases, by using these techniques, cells of the tissue were collapsed or otherwise visibly distorted. Figure 1 shows the results of fixation with 4.5% formaldehyde-gluteraldehyde followed by CPD. Almost all cellular detail has been obscured by the resulting shrinkage distortions. The larger cracks seen on the left of the picture may be due to dissection damage, rather than CPD. The results of observation of fresh tissue are seen in Fig. 2. Although there is a substantial improvement over CPD, some cell collapse still occurs.Due to these difficulties, it was decided to experiment with cold stage techniques. The specimens to be observed were dissected out and attached to the sample stub using a carbon based conductive paint in acetone.

To investigate the effectiveness of adding lemon peels and pulp extracts on some quality properties and shelf-life of the sheep longisimussdorsi muscle during refrigerated storage at 4±1°C for 0, 4, and 8 days for this purpose am meat trim of visible fat and connective tissue, they cut in small cubes. The meat samples divide into four equal proportions and mix with different concentrations of lemon peel and pulp extract according to the following formulations: Control; T1 1%; T2 2% and T3 3% of lemon peel and pulp extract, by applied immersion method. The results showed acceptable results of moisture content, Water-holding capacity cooking loss, thiobarbituric acid, met-myoglobin, myoglobin, and sensory traits of the samples treated with lemon peel in comparison to the control group. The phiso-chemical traits changed during the storage periods but the meat sample treated with lemon extract was more stable than control groups. These results suggested that using lemon peels and pulp extracts to maintain physio-chemical properties of ram meat and extend shelf-life during refrigerated storage, which may have implications of meat processors.

A substrate-directed enantioselective <i>anti</i>-carboboration reaction of alkenes has been developed, wherein a carbon based nucleophile and a boron moiety are installed across the C=C bond through a 5- or 6-membered palladacycle intermediate. The reaction is promoted by a palladium(II) catalyst and a mondentate oxzazoline ligand. A range of enantioenriched secondary alkylboronate products were obtained with moderate to high enantioselectivity that could be further upgraded by recrystallization. This work represents a new method to synthesize versatile and valuable alkylboronate building blocks. Building on an earlier mechanistic proposal by Peng, He, and Chen, a revised model is proposed to account for the stereoconvergent nature of this transformation.

Edible film and coatings are been looked upon for preservation of fruits, vegetables and bakery products. Extended shelf life with preservation of natural properties of food is always been a challenge; by incorporation of bio-actives in edible coatings, the shelf life can be increased as they are known for their antioxidant and antimicrobial properties. With this view, present study was undertaken, where edible coatings were prepared from starch, gelatin and glycerol and incorporated with Lemon peel extracts and coated on apples for increased shelf life. Antimicrobial activity of Lemon peel extracts was studied on eight organisms by broth dilution method and were found to be effective at concentration 3mg/mL-9mg/mL for bacteria and 50mg/mL- 90mg/mL for fungi. Fuji apples coated with starch-gelatin based edible formulation containing lemon peel extracts were studied for the effect of coating on fruit shelf life during storage for 28 days. Incorporation of lemon peel extract into edible coating improved shelf life with reducing rate of browning of apples.
