  • The superoxide dismutase(SOD)-like activities for 26 kinds of herbs and spices and 10 kinds of instant curry products were determined by measuring their abilites to reduce nitroblue tetrazolium. All samples showed the SOD-like activities. Rosemary, cassia, tarragon, allspice, oregano, bay leaves, basil, marjoram, thyme and star anise had higher activities than $10^5\;unit/g$ and clove had highest activity of $232,143{\pm}19.989\;unit/g$. The SOD-like activities for 10 kinds of instant curry products were in the range of $400{\sim}700\;unit/g$ when measured after heat treatment at $100^{\circ}C$ for 10 min. The water extracts of spices, herbs and curries were obtained by heat treatments of $25^{\circ}C$ for 60 min or $100^{\circ}C$ for 10 min, and their nitrite scavenging activity was measured at different pH conditions(1.2, 4.2 or 6.0). The nitrite scavenging activities were higher at acidic pH. However, the effects were not different from two heat treatments. The water extracts from cassia, bay leaves, allspices, oregano, staranise, rosemary, clove and tarragan had high nitrite scavenging activity(>90%) when they were measured at pH 1.2, and those from clove was highest $(97.58{\pm}0.88%)$. The pure curry used as raw materials for instant curry products had the nitrite scavenging activity in the range of $50{\sim}60%$ at pH 1.2 and the activity was not changed during the aging period$(0{\sim}12weeks)$. The ten brands of instant curry products had the nitrite scavenging activities of $12{\sim}28%$ at pH 1.2

  • The objective of this study was to find herbicidal compounds in the essential oil of palmarosa (Cymbopogon martini). Of essential oils from basil (Ocimum basilicum), blackpepper (Piper nigrum), clary sage (Salvia sclarea), ginger (Zingiber pfficinale), hyssop (Hyssopus officinalis), nutmag (Myristica fragrance), palmarosa (Cymbopogon martini), fennel (Foeniculum vulgare), sage (Salvia leucantha), and spearmint (Mentha spicta), the herbicidal activity of palmarosa essential oil, which was determined by a seed bioassay using rapeseed (Brassica napus L.), was highest ($GR_{50}$ value, $201{\mu}g\;mL^{-1}$). In palmarosa essential oil, 11 volatile organic chemicals were identified by gas chromatography-mass spectometry with solid-phase micro-extraction apparatus and the major constituents were geraniol (40.23%), geraniol acetate (15.57%), cis-ocimene (10.79%), and beta-caryophyllene (8.72%). The $GR_{50}$ values of geraniol, citral, nerol, and geranyl acetate were 151, 224, 452, and $1,214{\mu}g\;mL^{-1}$, respectively. In greenhouse and field experiments, foliar application of palmarosa essential oil at the level of $80kg\;ha^{-1}$ controlled weeds effectively. Overall results of this study showed that the herbicidal activity of palmarosa essential oil could be due to geraniol and citral which had lower $GR_{50}$ values.

  • Essential oil is a volatile substance obtained by physically obtaining fragrant plant materials made by one single plant and plant species, and is widely used for cosmetics, fragrances, and aroma therapy due to its excellent preservation, sterilization, and antibacterial effects. When essential oil would undergo the extraction and concentration processes, the agricultural chemicals thereof would be extracted and concentrated only to be harmful to the human body. This study analyzes 320 residual agricultural chemicals concentrated in the essential oil, and to this end, LC-MS/MS and GC-MS/MS are used, while the freezing process is applied instead of the conventional refining process hexane, to improve the preprocessing method. As a result of analyzing the essential oil, such ingredients as chlorpyrifos, piperonyl butoxide and silafluofen have been detected in Basil oil and Clove leaf oil. Hence, it is perceived that the residual agricultural chemicals should continue to be monitored for the essential oil.

  • Accumulated photon counts in immediate measurement after irradiation of marjoram, basil and thyme were shown to be below 625$\pm$162, 577$\pm$178 and 1261$\pm$640 Pc, respectively. The accumulated photon counts increased linearly with increasing irradiation doses up to 5 kGy and slightly increased from 5 kGy to 10 kGy. This trend was similar after storage periods. According to storage conditions, the difference of the accumulated photon counts was net clearly observed. The accumulated photon counts of irradiated spice samples decreased with increasing storage periods. The rate of decrease was higher in 5 and 10 kGy irradiated samples than that in 1 kGy, and in room conditions than that in darkroom conditions. The photon counts of the irradiated spice samples measured for 120 s were higher than those measured for 60 s. The irradiated spice samples showed higher photon counts than those of unirradiated samples in both room and darkroom conditions during all the storage periods. These results indicate that detection of irradiation was still possible after 24 weeks, although the PPSL signal of all spice samples decreased with increasing storage times.

  • The Construction industry in Yemen confronts many development constraints, such as the inadequate implementation of appropriate building materials and labour construction technologies. Thus, this research looks over building materials and labour construction technologies used on the local housing construction projects by verifying the percentage of construction expenditure consumed by the main construction components (Materials, Labour and Overhead and Profit), along with the implemented construction technologies. The paper conducts a survey to acquire the cost distribution of the construction main components. The outcomes of the survey were discussed; the discussion was supported by literature on similar issues from some countries. The outcomes confirmed the relatively limited percentage in labour cost and profit, and the elevated percentage of construction materials cost, which are because of the excessive and inappropriate use of materials. What's more, established that the excessively redundant unskilled labours are not effectively engaged in the construction activities, this is due to the tendency of the market in using labour-base technologies. This paper is to recommend a suitable policies and strategies has to be used to decrease cost by using efficiently appropriate construction practice and local materials, moreover take advantage of excessive labour to reduce unemployment.

  • Medicinal herbs are significant source of synthetic and herbal drugs. In the commercial market, medicinal herbs are used as raw drugs, extracts or tinctures. Isolated active constituents are used for applied research. For the last few decades, phytochemistry (study of plants) has been making rapid progress and herbal products are becoming popular. According to Ayurveda, the ancient healing system of India, the classical texts of Ayurveda, Charaka Samhita and Sushruta Samhita were written around 1000 B.C. The Ayurvedic Materia Medica includes 600 medicinal plants along with therapeutics. Herbs like turmeric, fenugreek, ginger, garlic and holy basil are integral part of Ayurvedic formulations. The formulations incorporate single herb or more than two herbs (poly-herbal formulations). Medicinal herb contains multitude of chemical compounds like alkaloids, glycosides, saponins, resins, oleoresins, sesquiterpene, lactones and oils (essential and fixed). Today there is growing interest in chemical composition of plant based medicines. Several bioactive constituents have been isolated and studied for pharmacological activity. R. cordifolia is an important medicinal plant commonly used in the traditional and Ayurvedic system of medicine for treatment of different ailments. This review illustrates its major constituents, pharmacological actions substantiating the claims made about this plant in the traditional system of medicine and its clinical applications.

  • Ocimum basilicum belongs to the family Lamiaceae and can be found in tropical Asia, Africa, Central America and South America. It is widely cultivated commercially as a condiment or for the production of essential oil. In this review, this plant is accredited with important effects on health, in addition to being a condiment. In folk medicine it is used to treat vomiting, intestinal colic and diarrhea, menstrual pains and to improve kidney function. Some studies have demonstrated that it can be used for the treatment of hyperlipidemia and also that it has antioxidant, neuroprotective, anti-inflammatory and vasodilator properties as well as hepatoprotective effects. In view of its broad range of effects, further studies should be conducted to ascertain the possible use of this plant in clinical trials, not only for prevention but also as an adjuvant in the treatment of different diseases.

  • This study aims to find out the characteristics and the type classification of contemporary public libraries in terms of browsing circuit. In so doing, it is to analyze 21 recently built libraries by using the browsing circuit, the spatial depth and the spatial layout. The study makes use of codes derived from the concept of 'Classification' and 'Frame' suggested by a pedagogist, Basil Bernstein. As a result, it shows that two codes are phased in overseas cases. In other words, one type is a lower depth of space and a high rate of rings with the multi-layer circuits and the three-dimensional circuit of multi-centered. the other type is the higher depth of space and a low rate of rings with the single-layer circuit and the multi-layer circuit of single-centered. In domestic cases, 4 types are shown. The characteristics of layout are seen as a radial shape and the rate of rings is lower than the overseas cases. It can be said that these results are a transitional phenomenon. For browsing circuit, domestic public libraries would be adapted to the three-dimensional circuit of multi-centered, a lower depth of space and a high rate of rings. By instructions of this plan, the real meaning of a public library will be come true.

  • Algeria is located at the Mediterranean coast of north Africa, 90% of its population is concentrated in the coastal area which is mainly devoted to agriculture. Highland steppe and vast desert climate have determined its food culture. Long arab domination has influenced food of Algeria which has also undergone certain impact of Spanish, Turkish and French occupation. A variety of agricultural products, vegetables, fruits, spices and herbs have determined cooking method and food combination of Algeria. It use neither pork nor alcohol. Its main food consists of bread made from wheat flour and couscous cooked with semoule, Mechuwi, roast lamb and chorba, mixed soup are also typical foods of this region. For climatic reason lamb and chicken are prefered. Energy efficient method is applied to cooking through using oil for saute and water for boiling. Under european influence, Algerian salad used dressing for leaf vegetables, root and other kind vegetables were boiled. Serving with cake and cookies as dessert may possibly be the influence from the French occupation. The cake and cookie are made of wheat flour or other grain flour and take a specific form to be fried sweet with honey. Herbs and spices are widely used in cooking which are easily cultivated in household: mint, basil, rosemary, bayleaf, thyme, sage, fennel, marjoram, coriander, celery. Garlic, onion, piment, red pepper, cinammon are also widely used in an ordinary cooking. Reasonable food combination and economic cooking method could be subject of Algerian food study.
