Nematicidal Effect of Paeonia Suffruticosa Constituents
Due to their harmful effects on the environmental phases, synthetic nematicides are now reappraised and the public concerns are tending to the natural nematicides as an alternative safe strategy for nematode control. The methanol extract of Paeonia suffruticosa leaves was tested for its activity at a concentration of 1000 ppm on the L1 larva and egg-bearing adult stages of Caenorhabditis elegans nematode and it proved to be active on both stages. The extract was fractionated to ten fractions by liquid partitioning followed by chromatographic separation on Sephadex LH-20 open column chromatography. The most active fraction (0.61 %) was hydrolyzed to its components with concentrated sulfuric acid and the resultant constituents were purified by thin layer chromatography (TLC) and paper chromatography (PC). These components were identified with 1H and 13C NMR spectroscopy to gallic acid and D-glucose, so the active constituent is a gallotannin derivative.

Effect of Drowning on Flowering and Seed Setting of Some Sugar Cane Varieties, at Alexandria, Egypt
Fourteen Varieties of sugar cane were chosen from the field of breeding programme in Sabahia Research Station at Alexandria during 2002 to 2005 seasons to study the effect of drowning on the flowering and seed setting of these varieties. Each variety was planted in two ridges. The length of ridge was 5 meters and the distance between the ridges was 125 cm. The rate of nitrogen fertilization was 100 Kg. It was added in three doses. It was after 75, 90 and 120 days from planting date. The rate of doses was equal. Irrigation was every 15 days with the exception of July and August. It was drowned at height 35 cm. It were covered the first and second Internodes. Drainage was every 3 days, and drowning again in the fourth day. All the other cultural practices were conducted for every two ridges in the similar manner whenever possible. The results obtained were as follows: The varieties were differed within and between for flowering dates, flowering percentage, seed setting, flowering duration and seedlings number. The seed setting varieties were differed between, while some varieties were seed setting and another were not seed setting. The seed setting were in the first ratoon only, while the plant crop and second ratoon the crossing were not succeeded. The seedlings number which were obtained were varied from one variety to another. Also some varieties did not enable to obtain the seedlings like the prior varieties.

Evaluation of Mango Trees Production Grown Between Date Palms
The effect of intercropping spacing on yield, fruit quality, and leaf chemical composition of Zebda mango trees grown among Zaghloul date palms at Rasheed region, EL-Behera Governorate, Egypt was studied to estimate a suitable intercropping spacing of mango trees on date palms. In general, Zebda mango trees grown at wide intercropping spacing (6×6 m.) produced the highest yield / tree, represented in increasing number of panicles / tree, number of flowers / panicle, number of fruits / tree and fruit retention % as compared with those at other intercropping spacing. In addition, wide intercropping systemsignificantly increased fruit quality, represented in fruit dimensions and weight of fruit and pulp with high content of TSS, non-reducing sugars and total sugars %. Likewise, it significantly increased leaf chlorophyll (a), (b), carbohydrates and some mineral content as N, P and K. Medium intercropping system (5×5 m.) produced middle values of the studied parameters followed by closed intercropping system (4×4 m.) which produced the lowest values in this respect. On the other words, wide intercropping spacing was most suitable for Zebda mango trees grown among date palms, which came in the first class in yield and fruit quality as compared with other intercropping systems and it was similar in most parameters to those of control (traditional cultivation 5×5 m.) and could be as a recommended system under conditions of this study, consequently growers can stop substitution of date palms with mango trees to maximize their output of the limited cultivated lands in this region.

Minimized Doses of Three IGIs – Compounds on the Following Generations of Spodoptera Littoralis, Boisd (Lep.; Noctuidae)
The efficiency of three insect growth inhibitors (IGIs); namely: Lufenuron, Flufenoxuron and Chlorfluazuron against the cotton leafworm Spodoptera littoralis was studied. The least efficient minimized doses were determined for measuring their delayed effect on the fitness components and reproductivity of the insect-pest; throughout sex following generations. Chlorfluazuron achieved superior toxic efficacy overall the other tested IGIs. In some cases of used lower concentrations, bleeding took place in the newly moulted larvae. The used lower concentrations of Flufenoxuron caused a case of antifeeding effect due to paralysis of the musculature of larval mouth parts. The tested IGI’s, slightly and insignificantly affected the durational periods of treated insect pest. The lowest measured weights of larvae, pupae; the least number of oviposited eggs and hatch percent was detected for the treatment of Flufenoxuron least minimized dose. The consequent treatment of the least efficient dose of each tested IGI to a more or less extent, reflected its drastic effect on the of developing stages. Besides the revealence of (F1) female-moths possessing shortened atrophied ovarioles with undifferentiated oöcytes. The calculated values of sterility and induced dominated lethals (genes) reaced its extremity at the end of 2nd generation in case of Flufenoxuron, the 6th Lufenuron and the 5th Chlorfluazuron causing the complete termination of the life cycle of the insect.

Time Distribution Patterns on Different Daily Activities and Its Relation to Some Socioeconomic Characteristics of Working and Non Working Women in Nawasa Village in Daqahlia Governorate
The present research was conducted to study time distribution patterns on different daily activities ( Productive , living , social and entertainment , sleep & rest time ) of working and non working women in Nawasa village in Daqahlia Governorate.
Data were collected from the sample which were selected by using questionnaire sheet, through personal interviews with 68 women under study. The sample included 34working and 34 non working women. Percentage, simple correlation and chi square test were used to statistically analyze data.
Data revealed that the educational levels of working women were better than that for non working women. The majority of working women (82.4%) had secondary, intermediate or high education. On the contrary the percentage of non working women having the above mentioned levels was (11.8%). The educational status for working women's husbands was better than those of non working women. The percentages of them having the high level of education accounted 79.4% , and 17.6% , respectively.
For more than half of working women sample had small family size (3-5 person ), whereas 67.6 % of non working women belonged to big families with more than 5 persons.
Land holding size for working women was better than that for non working women. However, animal holding showed the opposite trend.
The income and equipment holding were better for working women compared with those non working .
The data also showed that 61.7% from working women belonged to moderate socio-economic level, while more than half of the non working women (55.9%) were in the low level .
The daily time distribution pattern showed that the non working women spent more time in living activities than those working counterparts. Half of working women sample used to spend about 6 hours daily in their work. In the same time no differences were observed between the two samples working and housewives for time distribution on social & entertainment, sleep & rest.
The result also revealed that formal work time was significantly associated with the socio- economic level. Significant correlations were also found between work time and each of husbands education, women’s education number of owned equipment.
The results also showed a significant relationship between family size and the hours that housewife spend in living activities.

Effect of Some Sewing Variables on the Properties of Sewing Seams of Some Lining Fabrics
The research aimed at studying the effect of some Sewing variables represented in foot treadle pressure (normal/ high), and the sewing needle No. (16 , 18), and the sewing stitches number in centimeter (4/cm, 5/cm, 6/cm,) on the characteristics of sewing seams of some studied lining fabrics. These are represented in: Seam slippage (mm), elongation (mm), tensile strength of sewing seam (Newton), seam pucker degree, and percentage of sewing seam efficiency.
Aiming at identifying the best sewing variables of each textile material of lining fabrics which gives the best properties of the sewing seams, three types of lining fabrics from local markets as represented in two (100% polyster) fabric with a plain weave (1/1) and another fabric (100% viscose) with a twill weave (2/1). Natural and mechanical properties were identified in the weight average of square meter (gm), and the yarn count (denier /1), and fabric tensile strength (Newton), and elongation percentage, and the cutting time of lining fabrics in both directions of warp and weft (second). Samples of the three lining fabrics by the special sizes were prepared by the sewing seams properties' test and they were sewed by a polyester yarn (100%) obtained from the Arab company and Bolivara for textile & Weaving. Laboratorial tests of lining fabrics and their sewing seams were conducted in the laboratories of the weaving & textile industry fund in Seyouf. Experiments were divided into (72) experiments, (24) experiment for each type of lining fabrics using sewing variables which the study included.
Each experiment was conducted by two repetitions
in order to obtain the average of the sewing seams individually represented. After tabulating data and decoding them, relationships were calculated among the sewing variables and the sewing seam properties of lining fabrics using the variability analysis method (Test- f) at a nominal level (0.01).
The variation analysis results of the effects of the sewing variables' reaction on the sewing properties of the linings revealed the existence of a strong significant relationship among the sewing variables and the seam properties at the significance level (0.01). By calculating the least significant difference (L.S.D) of the sewing seam properties, the main effects of the reaction of sewing variables on the sewing seams properties were studied whether in individuals, triples. Each type of the studied sewing fabrics. They have shown the following: The first sample (100% Polyester) made the best results of sewing in the direction of warp by using the high pressure foot treadle and a needle number (18) and the stitches number (5/cm). As for the weft direction, the best results were made using a normal treadle foot pressure and needle No. (16) and stitches No. (5/cm). The second sample (100% Polyester) made the best results of sewing in the direction of warp by using the normal pressure foot treadle and a needle number (16) and the stitches number (5/cm). As for sewing in the weft direction, the best results were made using a normal treadle foot pressure and needle No. (18), and stitches No. (6/cm). The third sample (100% viscose) made the best results of sewing in the direction of warp by using the high pressure foot treadle and a needle number (16) and the stitches number (5/cm). As for the weft direction, the best results were made using a high treadle foot pressure and needle No. (18) and stitches No. (5/cm).

Effect of Lannite and Diazinon Pesticides on Some Soil Microorganisms
The studies of pesticides effects on soil microorganisms is very little, under soil conditions in Saudi Arabia. For that, two different functional groups of the most common used pesticides in Saudi Arabia namely lannate from the carbamates group and diazinon from the organophosphates group used in two soils types, Clay Loam and Sandy soils. The soils (with no history of pesticides treatment). The most important findings show that, the numbers of the total microbial colony counts, fungi, aerobic cellulose decomposers, phosphate dissolving bacteria, azotobacter and azospirilla have decreased due to the use of pesticides (whether lannate or diazinon) in the recommended field dose or the double does. The inhibitory effect was more evident with the use of the double recommended dose in both soils under investigation, and the inhibitory effects of diazinon pesticide was more than of lannate in both soil. However, the use of lannate in the doubled recommended field dose has had more effect on the actinomycetate numbers compared to diazinon at the same rates, and then comes the recommended dose of lannate and diazinon.The study also shows an increase in total nitrogen content whether in the clay loam soil or in the sandy soil. However, this increase varies according to the type of pesticides in use and it’s concentration in soil. At the same time, the relative amount of organic carbon has decreased on the addition of lannate and diazinon in both soil types.
