    Full Text Available Cashew apple juice (CAJ, produced from the native Brazilian cashew tree (Anacardium occidentale, and has been reported to have antibacterial, antifungal, antitumor, antioxidant and antimutagenic properties. Both the fresh unprocessed juice and the processed juice (cajuína in Portuguese has been shown to consist of a complex mixture containing high concentrations of anacardic and ascorbic acids plus several carotenoids, phenolic compounds and metals. We assessed both types of juice for their antimutagenic properties against the direct mutagens methyl methanesulfonate (MMS and 4-nitroquinoline-N-oxide (4-NQO and the indirect mutagen benzo[a]pyrene (BaP using pre-treatment, co-treatment and post-treatment assays with Salmonella typhimurium strains TA100, TA102, and TA97a. In pre-treatment experiments with strains TA100 and TA102 the fresh juice showed high antimutagenic activity against MMS but, conversely, co-treatment with both juices enhanced MMS mutagenicity and there was an indication of toxicity in the post-treatment regime. In pre-, co-, and post-treatments with TA97a as test strain, antimutagenic effects were also observed against 4-NQO and BaP. These results suggest that both fresh and processed CAJ can protect the cells against mutagenesis induced by direct and indirect mutagens.

Várias técnicas analíticas podem ser utilizadas visando à detecção da referida vitamina. Optou-se por utilizar o ensaio microbiológico oficial de determinação de folatos em alimentos, utilizando-se Lactobacillus casei como microrganismo de teste. Foram testados a utilização de ultrassom e tratamento enzimático como fases preparatórias, a fim de determinar qual a melhor metodologia a ser empregada. Foram comparados também o uso de padrões de ácido fólico e folato. Os resultados mostraram que o emprego de enzima é indicado como fase preparatória na determinação desta vitamina em suco de caju. A utilização de ultrassom não interferiu, significativamente, nos resultados encontrados, sendo seu emprego dispensável. Os teores de folato encontrados no suco de caju integral in natura indicam que o consumo de uma porção de 200 mL do suco equivale à ingestão de aproximadamente 500 µg de folato, valor superior à ingestão diária recomendada para adultos.Although cashew apple juice has been highly consumed in Brazil and several studies on its nutritional value have been published, no studies on the determination of folate contents in this juice were found in the literature. Several analytic techniques can be employed for the folate determination in foods. In this study, the microbiological assay using Lactobacillus casei was employed. Enzyme treatment and ultrasound waves were tested as pretreatment. The use of standards of folic acid and folate were also evaluated. The results showed that the enzyme treatment cannot be replaced by ultrasound treatment. The consumption of 200 mL of in natura cashew apple juice corresponds to a folate intake of 500 µg, which is higher than the recommended daily intake for adults.

    The extracts of Anacardium occidentale have been used in the management of different cardiovascular disorders in Nigeria. These have necessitated the assessment of the toxicity of this plant extract in sub-chronic administration. The inner stem bark of Anacardium occidentale was extracted with 80 % methanol and quantitatively analysed for antinutrients and some heavy metals. The phytochemical compositions and acute toxicity of the extract were determined also. Toxicity profiles of the extract on some liver function parameters were evaluated following a sub-chronic oral administration at doses of 1.44 and 2.87 g/kg. The phytochemical screening of extract revealed the presence of high amount of tannins, moderate saponins and trace of free reducing sugars. The antinutrient levels were 5.75 % (tannins), 2.50 % (oxalates), 2.00 % (saponins), 0.25 % (phytate) and 0.03 % (cyanide). The quantity of iron detected from dried crude was 8.92 mg/100 g, while lead and cadmium were non-detectable. The extract had LD(50)of 2.154g/kg p.o. in mice. Sub-chronic administration of the extract significantly increased the serum levels of alanine aminotransaminase and aspartate aminotransaminase, which are indicative of liver damage. The serum levels of alkaline phosphatase and total protein of the treated animals were not significantly increased. The effects of sub-chronically administered extract on hepatocytes were minimal as the serum alkaline phosphatase; total bilirubin and total protein levels in treated animals were not significant (p< 0.05). Thus, sub-chronic administrations of Anacardium occidentale inner stem bark extract did not significantly (p< 0.05) depress the function of hepatocytes in Wistar rats.

    Full Text Available The extracts of Anacardium occidentale have been used in the management of different cardiovascular disorders in Nigeria. These have necessitated the assessment of the toxicity of this plant extract in sub-chronic administration. The inner stem bark of Anacardium occidentale was extracted with 80 % methanol and quantitatively analysed for antinutrients and some heavy metals. The phytochemical compositions and acute toxicity of the extract were determined also. Toxicity profiles of the extract on some liver function parameters were evaluated following a sub-chronic oral administration at doses of 1.44 and 2.87 g/kg. The phytochemical screening of extract revealed the presence of high amount of tannins, moderate saponins and trace of free reducing sugars. The antinutrient levels were 5.75 % (tannins, 2.50 % (oxalates, 2.00 % (saponins, 0.25 % (phytate and 0.03 % (cyanide. The quantity of iron detected from dried crude was 8.92 mg/100 g, while lead and cadmium were non-detectable. The extract had LD 50 of 2.154 g/kg p.o. in mice. Sub-chronic administration of the extract significantly increased the serum levels of alanine aminotransaminase and aspartate aminotransaminase, which are indicative of liver damage. The serum levels of alkaline phosphatase and total protein of the treated animals were not significantly increased.

    Commercially available cashew (Anacardium occidentale L.) nut shell liquid (CNSL) mainly contains the phenolic constituents anacardic acid, cardol, and cardanol. These phenolic constituents are themselves heterogeneous, and each of them contains saturated, monoene, diene, and trienes in the fifteen-carbon side chain. This communication describes the separation of anacardic acid, cardol, and cardanol for industrial application. Anacardic acid was selectively isolated as calcium anacardate. The acid-free CNSL was treated with liquor ammonia and extracted with hexane/ethyl acetate (98:2) to separate the mono phenolic component, cardanol. Subsequently, ammonia solution was extracted with ethyl acetate/hexane (80:20) to obtain cardol. PMID:11368634

    In traditional Iranian medicine, the core of the fruit of Anacardium occidentale (cashew nut) has been used in the management of the pain. In this study gastric ulcerogenicity effect of the percolated extract of A. occidentale was investigated in rats. The extract or indomethacin (200, 300, 400 and 800 mg/kg) was administrated orally. In the control group normal saline (5 ml/kg) was used. After getting extract, indomethacin or normal saline, animals were slaughtered. The stomachs were detached and 10ml of 2% formalin injected in to the stomach for fixing the internal coat of the gastric wall. The stomachs were then slitted open near the bigger curvature and lacerations in the glandular part were evaluated. The ulcer index was determined using j-score. Data demonstrated that the oral dose of 200mg/kg of the extract did not provoke any ulcerogenic consequence in the rat's stomach. Gastric ulcerginicity of the extract at the doses of 300, 400 and 800 mg/kg was less than the similar doses of indomethacin (p<0.01). Therefore, A. occidentale is an appropriate plant for ongoing search for establishing an analgesic agent with low gastro-intestinal side effects for clinical use. PMID:22186317

  7. Influence of gamma radiation on the antioxidant action extracts from leaves of gross Anacardium occidentale Linn

    International Nuclear Information System (INIS)

    Anacardium occidentale Linn. is popularly known as cashew plant, found in Northeastern Brazil, is of great scientific interest because it contains high levels of bioactive compounds, such as polyphenols, flavonoids and tannins, which characterize their applications as natural antioxidants, which can contribute to protect against oxidative processes in the human body. This study aimed to evaluate the effects of 60Co gamma irradiation in the antioxidant action of the extracts of leaves of A. occidentale. The extracts of A. occidentale were extracted with 70% ethanol, evaporated under reduced pressure and divided into samples control and irradiation at 10 kGy. Subsequently analyzing the kidnapping of radical DPPH (concentrations of 6.25; 12.5; 25; 50; 100 and 200 ppm) and reducing power (concentrations of 25; 50; 100; 200; 400; 600; 800 and 1000 ppm). The results showed increased antioxidant actions dependent on the concentration and dose of 10 kGy in both assays. However, the kidnapping of DPPH activity showed variations from 50% to 92% for control, and 75% and 100% for irradiated. It is observed that the irradiated samples showed maximum activity (100%) in a 4-fold lower concentration (50 ppm) than the control samples. Featuring EC50 of standards BHT (235.8%) and vitamin C (63.5%) was very low compared with control extracts (8.1%) and irradiated (0.48). However the results obtained in this study indicate that extracts of leaves of A. occidentale irradiated at a dose of 10 kGy exhibit strong antioxidant activity against DPPH and power reducer, this paves its use as a natural source of antioxidants

    Commercially available technical cashew (Anacardium occidentale L.) nut shell liquid (CNSL) contains mainly cardanol (decarboxylated anacardic acid) and cardol. Cardanol, the monophenolic component of technical CNSL, is widely used as a synthon for the preparation of a number of polymers and agricultural products. This paper describes the separation of cardanol from toxic cardol. Technical CNSL was dissolved in a mixture of methanol and ammonium hydroxide (8:5) and extracted with hexane to obtain cardanol. The resultant methanolic ammonia layer was extracted with a mixture of ethyl acetate and hexane to yield cardol. This is the first industrially feasible process based on solvent extractions for the isolation of cardanol from technical CNSL. PMID:12137500

    Biological control of Biomphalaria glabrata that is the intermediate host of Schistosoma mansoni, through molluscicides has been an alternative against schistosomiasis. Many studies have been developed to obtain molluscicide products, from plants. Anacardium occidentale L. (cashew), a plant rich in phenolic compounds shows molluscicidal activity in earlier assays. However there is an interest of enhancing the action of bioactive substances in order to use it in small concentrations, reducing costs in their utilization. This study were conducted using ethanolic extracts of bark and leaves of A. occidentale, before and after exposure to gamma radiation from {sup 60}Co, checking their secondary metabolites, their biological activity against Biomphalaria glabrata and environmental toxicity. The extracts of A. occidentale were obtained by cold maceration in 70% ethanol, filtered, dried and divided into two experimental groups: control (0 kGy) and irradiated at a dose of 10 kGy. The quantification of metabolites was performed in six replicates for the determination of total phenols by Folin-Ciocalteau method and tannins, the precipitation of casein. Tests for biological control of embryos and adults of B. glabrata snails and assessment of environmental toxicity (using Artemia salina larvae) were performed in triplicate, following a period of 24 hours of exposure to extracts at a concentration of 100 mg/L and its respective controls. Data were expressed as percentages of means and standard deviations. The results showed that the gamma radiation from {sup 60}Co resulted in leaf extracts, increased levels of total phenols and tannins, which enhanced the lethality for embryos and adults of B. glabrata. There was a reduction of the toxicity of leaf extracts after irradiation in the Artemia salina. Since in extracts of bark, gamma radiation did not alter the levels of total phenols and tannins, however, it was noted potentiation of lethality of adult snails of B. glabrata. The

    Full Text Available Cashew (Anacardium occidentale is a medicinal plant native to Brazil and also yields a nutritious fruit juice. Its large pulpy pseudo-fruit, referred to as the cashew apple, contains high concentrations of vitamin C, carotenoids, phenolic compounds and minerals. Natural and processed cashew apple juice (CAJ/cajuina are amongst the most popular juices in Brazil, especially in the north-east. Both juices have antioxidant potential and suppress mutagenicity of hydrogen peroxide. In the present study we evaluated the inhibitory effects of CAJ/cajuina on Aflatoxin B1(AFB1-induced mutation, using the Salmonella/microsome assay with the experimental approaches of pre-, co- and post-treatments. Both CAJ/cajuina suppress AFB1-induced mutagenesis in strain TA102 when applied in co- and in post-treatment. Possible mechanisms for anti-mutagenicity in co-treatment are (a interaction with S9 enzymes, (b metabolization to non-mutagenic compounds of AFB1 or (c inactivation of S9 potential. Total suppression of AFB1 mutagenicity was observed in co-treatment with both CAJ and cajuina. Post-treatment anti-mutagenicity of both juices suggests a modulation of activity of error-prone DNA repair. CAJ/cajuina may be considered promising candidates for control of genotoxicity of AFB1 and may thus be considered as health foods with anti-carcinogenic potential. This promising characteristic warrants further evaluation with in vivo studies.

    The antiulcerogenic effect of a hydroethanolic extract of Anacardium occidentale L. leaves was investigated. The extract inhibited gastric lesions induced by HCl/ethanol in female rats. A dose-response effect study showed that the ED50 was 150 mg/kgb.w. Extract doses higher than 100 mg/kgb.w. were more effective than 30 mg/kg of lansoprazol in inhibiting gastric lesions. A methanolic fraction (257.12 mg/kg) which reduced gastric lesion at 88.20% is likely to contain the active principle of the antiulcer effect. No signs of acute toxicity were observed when mice were treated with extract dose up to 2000 mg/kgb.w. A chemical analysis of the extract allowed the identification of phenolic compounds as the major components. Glycosylated quercetin, amentoflavone derivate and a tetramer of proanthocyanidin were identified by liquid chromatography coupled to mass spectrometry. The level of total phenolics in the extract was evaluated at 35.5% and flavonoid content was 2.58%.

    The total dietary fiber, sugar, protein, lipid profile, sodium, and energy contents of 11 raw cashew kernel (Anacardium occidentale L.) samples from India, Brazil, Ivory Coast, Kenya, Mozambique, and Vietnam were determined. Total fat was the major component accounting for 48.3% of the total weight, of which 79.7% were unsaturated FA (fatty acids), 20.1% saturated FA, and 0.2% trans FA. Proteins, with 21.3 g/100 g, were ranked second followed by carbohydrates (20.5 g/100 g). The average sodium content was 144 mg/kg. Fourteen FA were identified among which oleic acid was the most abundant with a contribution of 60.7% to the total fat, followed by linoleic (17.77%), palmitic (10.2%), and stearic (8.93%) acids. The mean energy content was 2525 kJ/100g. Furthermore, the sterol profile and content, amino acids, vitamins, and minerals of four raw cashew kernel samples from Brazil, India, Ivory Coast, and Vietnam were determined. β-Sitosterol with 2380 ± 4 mg/kg fat was the most occurring sterol. Glutamic acid, with 4.60 g/100 g, was the amino acid with highest presence, whereas tryptophan with 0.32 g/100 g was the one with lower presence. Vitamin E with an average contribution of 5.80 mg/100 g was the most abundant vitamin. Potassium with a mean value of 6225 mg/kg was the mineral with highest amount in cashew samples. PMID:27004123

    Full Text Available Background: Oral health is an integral and important component of general health. Infectious diseases such as caries, periodontal, and gingivitis indicate the onset of imbalance in homeostasis between oral micro biota and host. The present day medicaments used in oral health care have numerous side effects. The uses of herbal plants as an alternative have gained popularity due to side effects of antibiotics and emergence of multidrug resistant strains. Anacardium occidentale (cashew and Mangifera indica (mango have been used as traditional oral health care measures in India since time immemorial. Materials and Methods: The ethanol extracts of cashew and mango leaves were obtained by maceration method. The antimicrobial activity was evaluated by clear zone produced by these plant extracts against Enterococcus faecalis, Staphylococcus aureus, Streptococcus mutans, Escherichia coli, and Candida albicans in agar plate method, determination of minimum inhibitory concentration (MIC, minimum bactericidal/fungicidal concentration (MBC/MFC, and suppression of biofilm. The cytotoxic effects of plants extract was determined by microculture tetrazolium assay on human gingival fibroblast and Chinese hamster lung fibroblast (V79 cell lines. Results: Cashew and mango leaf extract significantly (P < 0.05 produced larger zone of inhibition against test pathogens when compared to povidone---iodine-based mouth rinses. Although the MIC and MBC/MFC values of mouth rinses were effective in lower concentrations; plant extracts significantly (P < 0.001 suppressed the biofilms of oral pathogens. The leaf extracts were less cytotoxic (P < 0.001 compared to mouth rinses. Conclusions: Plant extracts are superior to the mouth rinses and have a promising role in future oral health care.

    International Nuclear Information System (INIS)

    Electromagnetic radiations are energies that can be classified as non-ionizing and ionizing. This type of energy is propagated by a material medium and the vacuum. The important characteristic of ionizing radiation is the localized release of large amounts of energy. The biological effects of radiation result principally from damage to DNA, which is the critical target. Given these harmful effects caused by radiation highlights the importance of acquiring knowledge about the radioprotective substance, because they act to protect the living tissue, decreasing the damage he caused by the effects of radiation. In this study we investigated the radioprotective effect of extract hydroalcoholic of Ziziphus joazeiro and Anacardium occidentale on embryos of Biomphalaria glabrata. The embryos of Biomphalaria glabrata pigmented were divided into 18 groups of 100 specimens. The experimental groups were exposed to the extracts at a concentration of 200 ppm and then irradiated.

    Full Text Available Background: Many reports showed that medicinal plant extracts cause alterations on the shape and physiology of erythrocytes. Objective: The present study seeks to ascertain the osmotic stability of sickle erythrocytes incubated in aqueous extracts of Anacardium occidentale, Psidium guajava, and Terminalia catappa. Materials and Methods: The fraction of erythrocytes lysed when suspended in saline solution of varying concentrations was investigated by spectrophotometric method. The percentage hemolysis of erythrocytes in the control and test samples showed a sigmoidal relationship with increasing concentrations of saline solution. Membrane stability was ascertained as mean corpuscular fragility (MCF index of erythrocytes incubated in 400 and 800 mg/dL aqueous concentrations of the three plant extracts. Results: The two experimental concentrations of P. guajava and T. catappa protected the erythrocytes against osmotic stress, as evidenced by decreases in the values of MCF compared with the control sample (P < 0.05. However, 800 mg/dL of A. occidentale promoted significant (P < 0.05 distabilization of sickle erythrocytes. Conclusion: Whereas the two experimental concentrations of aqueous extracts of P. guajava and T. catappa stabilized erythrocyte membrane, higher concentration (800 mg/dL of A. occidentale exhibited no membrane protective effect.

    Anacardium occidentale Linn. is popularly known as cashew plant, found in Northeastern Brazil, is of great scientific interest because it contains high levels of bioactive compounds, such as polyphenols, flavonoids and tannins, which characterize their applications as natural antioxidants, which can contribute to protect against oxidative processes in the human body. This study aimed to evaluate the effects of {sup 60}Co gamma irradiation in the antioxidant action of the extracts of leaves of A. occidentale. The extracts of A. occidentale were extracted with 70% ethanol, evaporated under reduced pressure and divided into samples control and irradiation at 10 kGy. Subsequently analyzing the kidnapping of radical DPPH (concentrations of 6.25; 12.5; 25; 50; 100 and 200 ppm) and reducing power (concentrations of 25; 50; 100; 200; 400; 600; 800 and 1000 ppm). The results showed increased antioxidant actions dependent on the concentration and dose of 10 kGy in both assays. However, the kidnapping of DPPH activity showed variations from 50% to 92% for control, and 75% and 100% for irradiated. It is observed that the irradiated samples showed maximum activity (100%) in a 4-fold lower concentration (50 ppm) than the control samples. Featuring EC{sub 50} of standards BHT (235.8%) and vitamin C (63.5%) was very low compared with control extracts (8.1%) and irradiated (0.48). However the results obtained in this study indicate that extracts of leaves of A. occidentale irradiated at a dose of 10 kGy exhibit strong antioxidant activity against DPPH and power reducer, this paves its use as a natural source of antioxidants.

    The aim of this work was to characterize the volatile fractions of two Brazilian honeys known as caju and marmeleiro. The volatile components were isolated by a column extraction technique using acetone as the extraction solvent. Totals of 59 and 36 volatile compounds were definitely or tentatively identified in the caju and marmeleiro honeys, respectively, using reference substances, mass spectral libraries, and the odor qualities of the compounds eluted from the GC column. Aroma extraction dilution analysis allowed the tentative identification of furfuryl mercaptan, benzyl alcohol, delta-octalactone, gamma-decalactone, eugenol, benzoic acid, isovaleric acid, phenylethyl alcohol, and 2-methoxyphenol as impact volatile compounds in the caju honey. In the marmeleiro honey, only isovaleric acid, gamma-decalactone, benzoic acid, and vanillin were considered to be potent odorants. This study showed that the medium- to high-boiling volatile compounds are important contributors to the characteristic aroma of these honeys. PMID:12475279

    Recent studies regarding the harmful effects of synthetic larvicides initiated the need to investigate for unconventional measures that are environmentally safe and target-specific against Aedes aegypti larvae. Thus, the main objectives of the study are to evaluate the larvicidal toxicity of the solvent fractions of Anacardium occidentale shell wastes against the third and fourth instar larvae of A. aegypti and to compare the results with the commercial larvicide product. The shell wastes were extracted with 95% EtOH followed by polarity-based fractionation. The fractions were tested for larvicidal activity according to the World Health Organization bioassay method. These were then characterized by quantitative thin-layer chromatographic (TLC) fingerprinting. The hexane fraction gave the strongest activity among the fractions with an LC50 of 4.01 mg/L and LC90 of 11.29 mg/L highly comparable to the commercial larvicide, which exhibited an LC50 of 1.71 mg/L and LC90 of 8.41 mg/L. The dichloromethane fraction exhibited 9.70 mg/L LC50 and 18.44 mg/L LC90. The remarkable toxicity effects exhibited by these fractions indicate their potential to provide core structures from which sustainable and environmentally safe plant-based larvicidal agents can be synthesized.

    The cashew tree (Anacardium occidentale) represents one of the major cheapest sources of non-isoprenoid phenolic lipids, which have a variety of biological properties: they can act as molluscicides, insecticides, fungicides, have anti-termite properties, have medicinal applications, and demonstrate antioxidant activity in vitro. Immature cashew nut-shell liquid (iCNSL) is a unique natural source of unsaturated long-chain phenols. Their use has stimulated much research in order to prepare drug analogues for application in several fields. The objective of the present study was to determine whether iCNSL has antioxidant properties when used in strains of the yeast Saccharomyces cerevisiae and to measure the inhibitory activity of acetylcholinesterase. The constituents were identified using thin-layer chromatography, gas chromatography-mass spectrometry, Fourier transform infrared spectroscopy, and (1)H and (13)C nuclear magnetic resonance. The iCNSL contains anacardic acid, cardanol, cardol, and 2-methyl cardol. Immature cashew nut oil contains triacylglycerols, fatty acids, alkyl-substituted phenols, and cholesterol. The main constituents of the free fatty acids are palmitic (C(16:0)) and oleic acid (C(18:1)). iCNSL has excellent protective activities in strains of S. cerevisiae against oxidative damage induced by hydrogen peroxide and inhibits acetylcholinesterase activity. iCNSL may have an important role in protecting DNA against damage induced by reactive oxygen species, as well as hydrogen peroxide, generated by intra- and extracellular mechanisms.

  19. Contribution of the cashew gum (Anacardium occidentale L.) for development of layer-by-layer films with potential application in nanobiomedical devices

    International Nuclear Information System (INIS)

    The search for bioactive molecules to be employed as recognition elements in biosensors has stimulated researchers to pore over the rich Brazilian biodiversity. In this sense, we introduce the use of natural cashew gum (Anacardium occidentale L.) as an active biomaterial to be used in the form of layer-by-layer films, in conjunction with phthalocyanines, which were tested as electrochemical sensors for dopamine detection. We investigated the effects of chemical composition of cashew gum from two different regions of Brazil (Piauí and Ceará states) on the physico-chemical characteristics of these nanostructures. The morphology of the nanostructures containing cashew gum was studied by atomic force microscopy which indicates that smooth films punctuated by globular features were formed that showed low roughness values. The results indicate that, independent of the origin, cashew gum stands out as an excellent film forming material with potential application in nanobiomedical devices as electrochemical sensors. Highlights: ► This study focused on the use of cashew gum for the formation of LbL films. ► LbL films containing cashew gums were investigated by AFM and cyclic voltammetry. ► Cashew gum contributed to obtain stable films with well-defined redox processes. ► Cashew gum films detected dopamine in low concentrations. ► These LbL films presented potential application in nanobiomedical devices.

The morphology of the nanostructures containing cashew gum was studied by atomic force microscopy which indicates that smooth films punctuated by globular features were formed that showed low roughness values. The results indicate that, independent of the origin, cashew gum stands out as an excellent film forming material with potential application in nanobiomedical devices as electrochemical sensors. Highlights: Black-Right-Pointing-Pointer This study focused on the use of cashew gum for the formation of LbL films. Black-Right-Pointing-Pointer LbL films containing cashew gums were investigated by AFM and cyclic voltammetry. Black-Right-Pointing-Pointer Cashew gum contributed to obtain stable films with well-defined redox processes. Black-Right-Pointing-Pointer Cashew gum films detected dopamine in low concentrations. Black-Right-Pointing-Pointer These LbL films presented potential application in nanobiomedical devices.

    Due to the growing environmental awareness on the negative impact resulting from utilization of fossil fuels, and in the search for renewable energy sources, biofuels' interest as Bioethanol has rapidly expanded recently. In this context, lignocellulosic compounds have become center of attention as an abundant and economic alternative source of carbohydrates for ethanol production. In this study, cashew's bagasse acid hydrolysis was initially studied for glucose synthesis and its fermentation towards ethanol production. Sulfuric acid concentration, solids concentration and time were some of the factors evaluated. The highest glucose productivity value (162,9 mg.g de bagaco{sup -1}) , was obtained for 0,6 mol.L{sup -1} of sulfuric acid in an autoclave at 121 deg C for 15 min. For the fermentation of the hydrolyzed material by S. cerevisiae containing 16 {+-} 2,0 g.L{sup -1} of glucose metabolic, the yield and productivity obtained were 0,63 g-g glucose{sup -1} and 1,43 g.L{sup -1}h{sup -1} respectively. Ethanol concentration after 6 h of fermentation of this hydrolyzed was 11 g.L{sup -1}. In the best conditions of acid hydrolysis, a second pre-treatment with diluted sulfuric acid was performed to evaluate availability of hemicelluloses at 160 deg C and 180 deg C. For comparative purposes, alkali pre-treatment was evaluated under the conditions of 0,6 mol.L{sup -1}, 30% p/v of bagasse thermically treated at 121 deg C for 15 minutes. However, concentration of sugars was not sufficient for fermentation. Also, nitrogen supplementation of the hydrolyzed fraction did not influence significantly ethanol production. The results demonstrate that the hydrolyzed fraction from the acid pre-treatment of cashew's bagasse could be utilized for ethanol production. (author)

    Plant materials rich in phenolic compounds, such as Anacardium occidentale Linn., Have been used as alternatives to synthetic pesticides in Biomphalaria glabrata control programs, intermediate host of Schistosoma mansoni. Studies show that ionizing radiation can influence the content of phenolic compounds and thus their biological actions. The aim of this study was to evaluate the influence of gamma radiation of {sup 60}Co in polyphenol composition of hydroalcoholic extracts of bark and leaves of A. occidentale and evaluate the toxicity of these extracts to embryos and adults of B. glabrata. To achieve this goal this, the extracts were irradiated at 10 kGy, the controls being maintained from 0 kGy and positive (CaCO{sub 3}) and negative (H{sub 2}O). We quantified the total phenols by the Folin-Ciocalteau and tannins by precipitation of casein. Extracts were used at a concentration of 100 mg/L. The results showed that the radiation caused the changes to the leaves, the percentage of polyphenols and tannins, and the percentage of lethality in embryos and adults Biomphalaria glabrata, these percentages being: 13 ± 5 (0 kGy) and 27 ± 2.5 (10 kGy), and 36.67 ± 5.77 (0 kGy), and 56.67 ± 5.77 (10 kGy), respectively. Gamma radiation caused significant changes in the levels of polyphenols in the extracts of leaves of Anacardium ocidentale Linn., translated by the increased toxicity of this extract against embryos and adults of Biomphalaria glabrata. This indicates that gamma radiation can be used as an agent potentiating the toxicity of plant extracts on the alternate use of these materials as molluscicides. (author)

    In this study the content of anacardic acids, cardanols and cardols in cashew apple, nut (raw and roasted) and cashew nut shell liquid (CNSL) were analysed. The higher amounts (353.6 g/kg) of the major alkyl phenols, anacardic acids were detected in CNSL followed by cashew fibre 6.1 g/kg) while the lowest (0.65 g/kg) amounts were detected in roasted cashew nut. Cashew apple and fibre contained anacardic acids exclusively, whereas CNSL also contained an abundance of cardanols and cardols. Cashew nut (raw and roasted) also contained low amounts of hydroxy alkyl phenols. Cashew nut shell liquid was used for a basic fractionation of the alkyl phenol classes and the individual anacardic acids, major cardanols and cardols were purified to homogeneity from these fractions by semi-preparative HPLC and definitively identified by nano-ESI-MS-MS, GC-MS and NMR analyses. The hexane extracts (10 mg/ml) of all cashew products tested plus CNSL, displayed significant antioxidant capacity. Cashew nut shell liquid was the more efficient (inhibition=100%) followed by the hexane extract of cashew fibre (94%) and apple (53%). The antioxidant capacity correlated significantly (Pcardanols (IC50>4.0 mM). The data shows that of these substances, anacardic-1 was by far the more potent antioxidant (IC50=0.27 mM) compared to cardol-1 (IC50=1.71 mM) and cardanol-1 (IC50>4.0 mM). The antioxidant capacity of anacardic acid-1 is more related to inhibition of superoxide generation (IC50=0.04 mM) and xanthine oxidase (IC50=0.30 mM) than to scavenging of hydroxyl radicals. At present a substantial amount of cashew fibre is mostly used in formulations of animal or poultry feeds. The data presented in this study, indicates that this waste product along with CNSL, both of which contain high contents of anacardic acids, could be better utilized in functional food formulations and may represent a cheap source of cancer chemopreventive agents.

    In this preliminary study, we are looking at levels 32P and depths of soil injections on uptake by plants using the injection techniques in root activity studies. 32P activities can be detected in the leaves and flower parts of plants two weeks after injection in the soil. Reasonable count rate can be obtained by using lower level of 32P (1.6 mCi/tree) than recommended (5 mCi/tree). 32P counts were higher in younger than older leaves. Flowers had the least count. Differences in injection depths (5 and 15 cm) could not be detected. Differences in count rate were detected due to position of leaves and flowers (upper and lower canopy) in some of the sampling intervals. (author)

    Dynamic high pressure (DHP) appears to be an alternative approach to physical modification of polysaccharides aimed improving their technological properties. Therefore, its effect on the functional properties of polysaccharides (i.e., oil absorption capacity, emulsifier, and rheology) needs to be investigated. Cashew tree gum (CG) is a biological macromolecule that has been proposed to be used as an emulsifier in beverage emulsions. To the best of our knowledge, none of the articles in the literature investigates the effect of DHP on the CG properties. This work presents a study on the evaluation of the effects of DHP on functional characteristics of CG, including rheological properties, molecular weight, glycosyl-linkage analysis, solubility, swelling and oil absorption capacity (OAC). The results suggest that DHP is able to modify the technological properties of cashew tree gum (increasing solubility and decreasing apparent viscosity). PMID:26050904

    Cashew apple is a tropical pseudofruit consumed as juice due to its excellent nutritional and sensory properties. In spite of being well known for its important antioxidant properties, the cashew apple has not been thoroughly investigated for its therapeutic potential. Thereby, this study evaluated the antioxidant capacity, anti-inflammatory, and wound-healing activities of cashew apple juice. Juices from ripe and immature cashew apples were analyzed for antioxidant, anti-inflammatory, and wound-healing properties. Those were evaluated in murine models of xylene-induced ear edema and wound excision. Swiss mice were treated with cashew juice by gavage. Edema thickness was measured and skin lesions were analyzed by planimetry and histology. Both antioxidant content and total antioxidant activity were higher in ripe cashew apple juice (RCAJ) than in unripe cashew apple juice (UNCAJ). The UNCAJ presented the main anti-inflammatory activity by a significant inhibition of ear edema (66.5%) when compared to RCAJ (10%). Moreover, UNCAJ also showed the best result for wound contraction (86.31%) compared to RCAJ (67.54%). Despite of higher antioxidant capacity, RCAJ did not promote better anti-inflammatory, and healing responses, which may be explained by the fact that treatment increased antioxidants level leading to a redox "imbalance" turning down the inflammatory response modulation exerted by reactive oxygen species (ROS). The results suggest that UNCAJ presents a greater therapeutic activity due to a synergistic effect of its phytochemical components, which improve the immunological mechanisms as well as an optimal balance between ROS and antioxidants leading to a better wound healing process.

  17. The effects of gamma irradiation on cashew (Anacardium occidentale L.) and mangosteen (Garcinia mangostana L.)

    International Nuclear Information System (INIS)

    A study on the effects of gamma radiation on cashew and mangosteen was conducted. In cashew seeds exposed to gamma radiation with dose raging from 100 to 400 Gy, the highest percentage emergence of 80% was obtained in the control and 100 Gy. Percent emergence decreased from 200-400 Gy. Seeds irradiated with 400 Gy gave the lowest percentage of only 10%, 4 weeks after sowing, Slight increase in emergence was observed at low dose of 5 and 10 Gy gamma rays over that of the control in mangosteen. However, at doses 20 and 30 Gy, percent emergence decreased. No shoot emergence was noted at 40 Gy, 7 weeks after sowing. In both cashew and mangosteen, gamma irradiation caused a decreased in seedling height and increased frequency of induced morphological changes (leaf abnormalities, stem bifurcation, reduction in internode length and changes in chlorophyll pattern). Differences in response of cashew and mangosteen to gamma radiation were attributed to species and dosage of radiation used. Based on the foregoing results, gamma radiation is an effective mutagenic agent in inducing morphological as well as genetic changes in both tree crop species. In the micropropagation of mangosteen using the in-vitro culture system, the best treatment for callus induction was MS basal medium and MS with 2 mg/1 BA; for root formation, the best treatment combination was 4 mg/ 1 BA + 6 mg/1 NAA; and for plantlet regeneration, the optium treatment was MS with 6 mg/1 BA + 6 mg/1 NAA.

    Full Text Available Effluents generated by the textile industry are of environmental concern because of the presence of dyes with complex molecular structure, which confer them recalcitrant characteristics. Indigo is one of the most widely used dyes within the textile sector and studies have suggested that edible fungi may be capable of its biodegradation. A textile effluent was mixed with sugarcane bagasse and inoculated with Pleurotus sajor-caju, the decolorization being evaluated after 14 days, when the process was observed. Enzymatic activities of laccase, peroxidase and manganese peroxidase were determined, the production of these ligninolytic enzymes being evident and a synergism among them being likely in the decolorizing process.

    Full Text Available Glucose produced by gluconeogenesis and glycogenolysis plays an important role in aggravating hyperglycemia in diabetes, and altered mitochondrial function is associated with impaired energy production. The present study focuses on the effect of Semecarpus anacardium on carbohydrate metabolism and energy production in diabetic rats. Diabetes was induced by the administration of Streptozotocin at a dose of 50 mg/kg.b.wt. Three days after the induction, Semecarpus anacardium at a dose of 300 mg/kg.b.wt was administered for 21 days. After the experimental duration, the activities of the enzymes involved in Glycolysis, TCA cycle, gluconeogenesis, and glycogen were assayed in the liver and kidney of the experimental animals. In addition, to the complexes the protein expression of AKT and PI3K were assayed. The levels of the enzymes involved in Glycolysis and TCA cycle increased, while that of gluconeogensis decreased. The activities of the mitochondrial complexes were also favorably modulated. The expressions of PI3K and AKT also increased in the skeletal muscle. These effects may be attributed to the hypoglycemic and the antioxidative activity of Semecarpus anacardium. The results of the study revealed that Semecarpus anacardium was able to restore the altered activities of the enzymes involved in carbohydrate metabolism and energy production.

Methods: Male albino rats were fed with a 50 % ethanolic extract of Semecarpus anacardium fruit at 100 mg·kg-l·day-1, 200 mg·kg-l·day-1 and 300 mg·kg-1·day-1 for 60 days. Fertility test was performed after 60 days of treatment. Sperm motility and density were observed in the cauda epididymis. Biochemical and histological analyses of the blood and reproductive organs were done. Recovery of fertility was followed to evaluate the reversibility of drug action. Results: S. anacardium fruit extract administration resulted in spermatogenic arrest in albino rats. Thes perm motility and density was reduced significantly. The RBC and WBC counts, haemoglobin, haematocrit, blood sugar and urea were found to be within the normal range in the whole blood. The protein, cholesterol and glycogen in the testes and the fructose in the seminal vesicle were significantly decreased after the treatment. The fruit extract feeding caused marked reduction in the number of primary spermatocytes, secondary spermatocytes and spermatids.The number of mature Leydig cells was also decreased and degenerating cells increased proportionately. Conclusion:S. anacardium fruit extract causes spermatogenic arrest in albino rats. ( Asian J Androl 2003 Jun; 5: 121-124)

    Pleurotus sajor-caju (Fr.) Singer was cultivated on selected agro wastes viz. cotton stalks, groundnut haulms, soybean straw, pigeon pea stalks and leaves and wheat straw, alone or in combinations. Cotton stalks, pigeon pea stalks and wheat straw alone or in combination were found to be more suitable than groundnut haulms and soybean straw for the cultivation. Organic supplements such as groundnut oilseed cake, gram powder and rice bran not only affected growth parameters but also increased yields. Thus bioconversion of lignocellulosie biomass by P. sajor-caju offers a promising way to convert low quality biomass into an improved human food.

    A putative Hsp100 gene was cloned from the fungus Pleurotus sajor-caju. mRNA expression studies demonstrated that this gene (designated PsHsp100) is highly induced by high temperature, induced less strongly by exposure to ethanol, and not induced by drought or salinity. Heat shock induction is detectable at 37°C and reaches a maximum level at 42°C. PsHsp100 mRNAlevels sharply increased within 15 min of exposure to high temperature, and reached a maximum expression level at 2 h that was maintained for several hours. These results indicate that PsHsp100 could work at an early step in thermotolerance. To examine its function, PsHsp100 was transformed into a temperature-sensitive hsp104 deletion mutant Saccharomyces cerevisiae strain to test the hypothesis that PsHSP100 is an protein that functions in thermotolerance. Overexpression of PsHSP100 complemented the thermotolerance defect of the hsp104 mutant yeast, allowing them survive even at 50°C for 4 h. These results indicate that PsHSP100 protein is functional as an HSP100 in yeast and could play an important role in thermotolerance in P. sajor-caju.

    The effect of lignin containing natural substrates corn-cob, coir-dust, saw-dust, wheat straw and bagasse particles on the extracellular secretion of laccase in the liquid culture growth medium of Pleurotus sajor-caju MTCC 141 has been studied. The culture conditions for maximum secretion of laccase by Pleurotus sajor-caju MTCC 141 have been optimized. Homogeneous preparation of laccase from the culture filtrate of the fungus has been achieved using ammonium sulphate precipitation, anion exchange chromatography on DEAE and gel filtration chromatography on Sephadex G-100. The purified enzyme preparation gave a single protein band in SDS-PAGE analysis indicating a molecular weight of 90 kD. The enzymatic characteristics Km, kcat, pH and temperature optima of the purified laccase have been determined using 2, 6-dimethoxyphenol as the substrate and have been found to be 35μmol/L, 0.30 min-1, 4.5 and 37℃ respectively. The Km values for the other substrate like catechol, m-cresol, pyrogallol and syringaldazine have also been determined which were found to be 216 μmol/L, 380 μmol/L, 370 μmol/L and 260 μmol/L respectively.

    Full Text Available Nel mondo occidentale, saper scrivere signífica il massimo della competenza. Perfino nella percezione popolare il ruolo che in musica spetta alla scrittura è percepito come una sfida. Nel marzo 2010, in una trasmissione televisiva equivalente a “Scommettiamo che”, un anchorman tedesco ha chiesto ad Anna Netrebko, sua ospite, se nella carriera di una cantante sia necessario saper leggere perfettamente la musica. “No”, è stata la risposta, istantanea, “basta avere bella voce e buona memoria”. Accostatasi poi al pianoforte per intonare un Lied di Rimskij-Korsakov, mentre l’accompagnatrice apriva lo spartito, la Netrebko aggiungeva scherzosamente: il pianista sì che deve saper leggere la musica! Per l’esperto, questa maliziosa risposta a doppio senso richiama l’antica distinzione erudita tra sapere pratico e teorico, rappresentati rispettivamente dalla voce umana, di cui ciascuno dispone in natura, e da uno strumento tecnico tradizionalmente adibito alla teoria, erede del monocordo antico, sulla cui tastiera le divisioni della corda erano indicate con lettere alfabetiche: lettere che sono le primissime testimonianze di una scrittura musicale.

    Full Text Available Abstract— Grey oyster mushroom (Pleurotus sajor-caju is one of the edible mushrooms from Pleurotus family, which is cultivated commercially in Malaysia. The global mushroom market has shown remarkable growth in recent years and has attractive market potential for the future. This study aimed to determine nutritional value and antioxidant properties of fresh grey oyster mushroom (Pleurotus sajor-caju with the intention to give better information on nutritional composition of fresh oyster mushroom cultivated on rubber sawdust. Grey oyster mushrooms were freshly harvested from Teloi Agro Farm, Kedah, Malaysia. The proximate analysis was used to determine nutrient composition of grey oyster mushroom. Highest nutritional value of grey oyster mushroom is the moisture content (90.10±0.09%, followed by crude fibre content (17.27±1.08%, protein content (4.00±0.31%, carbohydrates content (3.54±0.09%, while the lowest nutritional value was possessed by fat content (1.18±0.33% and ash content (1.16±0.02%. The antioxidant activities of the mushroom were measure using total phenolic content (TPC by Folin-Ciocalteu reagent method and 2, 2-diphenyl-1-picrylhydrazyl radical scavenging (DPPH assay. The hot water extract showed mushroom powder possessed 2.21±0.03 mg GAE/g of dried mushroom powder for total phenolic content and at concentration of 0.1g/ml it can inhibit 89.29% of DPPH radicals. By virtue of having high fibre with low fat and high antioxidant activity, grey oyster mushroom can be considered as a functional food, which can provide health benefits.

    The objective of this study was to evaluate the potential of Anacardium humile (monkey nuts) against Aedes aegypti larvae. Hexane, ethanol and aqueous extracts and oil from leaves were obtained from plant material collected from the Brazilian savanna. These were tested at concentrations of 1%, 0.5%, 0.25%, 0.125%, 0.05% and 0.0125%, diluted in 1% dimethyl sulfoxide. The dead larvae were counted 24 hours later. The Probit analysis method was used to obtain the LC(50) and the respective confidence intervals. The conclusion was that only the oil extracted from Anacardium humile leaves caused 100% mortality among fourth-instar Aedes aegypti larvae, using concentrations of up to 0.125%. This seems to indicate that the active ingredients are present in the most apolar phase. This indicates that this plant has potential use as a larvicide against Aedes aegypti. However, new tests should be carried out using other plant organs, as well as using other methods and solvents for the extraction.

    Objective: To explore the protective effect of the drug Semecarpus anacardium (S. anacardium) on altered glucose metabolism in diabetic rats. Methods: Type 2 diabetes mellitus was induced by feeding rats with high fat diet followed by single intraperitoneal injection of streptozotocin (STZ) (35 mg/kg b.w.). Seven days after STZ induction, diabetic rats received nut milk extract ofS. anacardium Linn. nut milk extract orally at a dosage of 200 mg/kg daily for 4 weeks. The effect of nut milk extract of S. anacardium on blood glucose, plasma insulin, glucose metabolising enzymes and GSK were studied. Results: Treatment with SA extract showed a significant reduction in blood glucose levels and increase in plasma insulin levels and also increase in HOMA - β and decrease in HOMA -IR. The drug significantly increased the activity of glycolytic enzymes and glucose-6-phosphate dehydrogenase activity and increased the glycogen content in liver of diabetic rats while reducing the activities of gluconeogenic enzymes. The drug also effectively ameliorated the alterations in GSK-3 mRNA expression. Conclusions: Overall, the present study demonstrates the possible mechanism of glucose regulation of S. anacardium suggestive of its therapeutic potential for the management of diabetes mellitus.

    Full Text Available Compuesta por los departamentos de Antioquia, Caldas, Quindío, Risaralda y Valle del Cauca, los Andes Occidentales ha sido por mucho años una de las regiones más prósperas de Colombia. Esta prosperidad se ha traducido en condiciones de vida e infraestructura superiores a las del resto del país. El éxito y bienestar que presentan hoy en día los Andes Occidentales están estrechamente ligados a la concentración de la producción de café, que se dio allí durante gran parte del siglo XX. El arraigo del café en la región no sólo se dio debido a que la geografía ofrecía las condiciones ideales para el cultivo, sino también a las instituciones cafeteras creadas para organizar la industria del café. A pesar de esta prosperidad, el constante descenso del precio internacional del café después del rompimiento del pacto de cuotas de producción en 1989, sumado al estancamiento de la industria manufacturera en algunos departamentos de la región, han afectado las economías departamentales menos diversificadas. Es así como la región de los Andes Occidentales Colombianos presenta las tasas de desempleo más altas del país, tasas que se han visto afectadas aún más con la crisis financiera internacional a través del menor flujo de remesas que los trabajadores oriundos de la región, y residentes en el exterior envían a sus familias.

Alguns estudos reportam a possibilidade de aplicação industrial da goma exsudada do cajueiro em substituição à goma arábica devido à semelhança estrutural e química. Neste estudo propôs-se caracterizar comparativamente algumas propriedades destas duas gomas, antes e após dois tratamentos de extrusão termoplástica. Nos resultados de composição centesimal as amostras de goma de cajueiro in natura e processadas destacaram-se pelo alto teor de fibra solúvel. Por outro lado, apresentaram menor teor de minerais que a goma arábica. Por meio da análise de viscosidade rápida, foi observado que este parâmetro aumentou nas amostras de goma arábica processadas, enquanto nas amostras processadas de goma de cajueiro houve redução. Nos resultados da análise de difração de raios X predominou-se a conformação amorfa das cadeias poliméricas de ambas as amostras. A partir dos parâmetros avaliados, a goma de cajueiro poderia ser indicada como substituta da goma arábica.

J’ai alors été contacté par le Conservatoire Claude Debussy, situé dans le 17eme arrondissement de Paris, afin d’effectuer une recherche comparative sur le Jazz et la musique folklorique Turque. Dans ce contexte j'ai participé aux cours de jazz de Philippe Poussard avec mon instrument authentique turc nommé "bağlama". Avec ce dernier nous avons joué des chansons folkloriques Turques, et j'ai ressenti que lui et ses étudiants ont été impressionnés par la musique que nous avons jouée ensemble, enimprovisant. Nous avons ensuite discuté de différents sujets à propos des musiques Turque et Occidentale. J'ai alors constaté que les étudiants de ce conservatoire n'ont aucune connaissance sur la musique Turque en générale. J'ai alors décidé d’effectuer une analyse théorique sur les questions fondamentales de la musique Occidentale etde la musique Turque. Je pense qu'il est important de donner des informations sur la théorie de la musique dans les établissements scolaires occidentaux. Ceci est important pour la communication entre les deux cultures musicales. En rédigeant mon article j'ai utilisé la méthode d'analyse de documents. J'ai aussi utilisé mes expériences personnelles acquises au Conservatoire pour faire un travail de comparaison appliquée. J'ai constaté qu'en termes de gamme, rythme et tonalité il y avait beaucoup de différences mais également des similitudes dans la musique Turque et Occidentale.

    International Nuclear Information System (INIS)

    The production and consumption of edible mushrooms has been increasing in the last years due to its nutritional composition and sensory quality. The irradiation of mushrooms has been used with the purpose of maintaining the fresh product characteristics during shelf-life. The present study evaluated the effect of different radiation doses on the conservation of mushrooms Pleurotus sajor-caju, through by chemical, physical, microbiological and sensorial parameters. The packaging consisted on polystyrene trays with 250 g of sample, wrapped in polyvinyl chloride (PVC). The mushrooms were irradiated with doses of 125, 250, 500 and 750 Gy in a Gamma cell 220 type irradiator, and stored at 4 ± 1 deg C and 90% UR for 10 days. The proximate composition (moisture, crude fibre, total protein, total fat and ash), total soluble solids, pH, texture, color (L, a, b, Chroma and ho), enzymatic activity (polyphenoloxidase and peroxidase), microbiological (total coliform, Escherichia coli and total psychotropic bacteria) and sensory evaluation (color, taste and appearance) were determined in the 1st, 5th and 10th storage days. For the respiratory rate analysis, 30 g of sample were placed in jars and stored at 4 ± 1 deg C and 90% UR for 8 days. CO2 was analyzed every day using a gaseous chromatograph. The results were submitted to variance analysis and average test using the SAS statistical package. The total protein and total fat values did not differ significantly between treatments or storage periods, while the moisture, crude fibre and ash values differ between treatments and periods. The dose of 750 Gy darkness the mushroom in the last evaluation, and texture was better in control during the storage period. The color (L, a), texture and proximate composition values did not differ significantly between treatments or storage periods. A significant increase was observed for soluble solids, b* and enzymatic activity values in all treatments at the end of the storage period. Values

    Laccases are multicopper oxidoreductases with broad substrate specificity and are applied in biofuel cells at the cathode to improve its oxygen reduction performance. However, the production of laccases by e.g. fungi is often accompanied by the need of synthetic growth supplements for increased enzyme production. In this study we present a strategy for the white-rot fungus Pleurotus sajor-caju for natural laccase activity induction using lignocellulose substrates and culture supernatant of Aspergillus nidulans. P. sajor-caju laccases were secreted into the supernatant, which was directly used at a carbon-nanotube buckypaper cathode in a biofuel cell. Maximal current densities of -148±3μAcm(-2) and -102±9μAcm(-2) at 400mV were achieved at pH 5 and 7, respectively. Variations in cathode performance were observed with culture supernatants produced under different conditions due to the induction of specific laccases. PMID:27393835

    In solid state fermentation, Pleurotus sajor-caju has been found to be able to degrade at least 30% oil palm empty Fruit Bunch (EFB) fibre leaving 70 % useful materials. Conditions under which fermentation carried out were investigated. It was found that, in the temperature range between 25- 28 °C, relative ph between 6-8, moisture between 60-70 % and medium composition of CaCO 3: rice bran 2 %: 5 % were the optimum conditions. The results showed in fermented products that, there were substantial reduction in cellulosic component such as Crude Fiber (CF, 18 %); Acid Detergent Fibre (ADF, 45 %), Neutral Detergent Fibre (NDF, 61 %) and Acid Detergent Lignin (ADL, 14 %). However, Crude Protein (CP, 10%) increased resulted from single cell protein enrichment of mycelial microbial mass. The mass reductions of substrate in fermentation process corresponds to the CO 2 released during fermentation. Hence, attributable to the decreased in content of CF, ADF, NDF, and ADL. The digestibility study has also been carried out to determine the useful level of this product to ruminant. Aflatoxin content was detected low in both the initial substrates and products. Based on nutritional value and low content of aflatoxin, the product is useful as a source of roughage to ruminant.

    2013-01-01

    Full Text Available In this study, superfluous jute plants and jute stick were converted into upgraded animal feed by solid state fermentation (SSF using a cellulolytic fungus, Pleurotus sajor-caju. Prior to fermentation, substrates were subjected to several pretreatments such as soaking with water overnight and alkali or lime pretreatment. SSF was carried out with 20 g of substrate in 100 ml conical flask and was incubated at 30C for 8 weeks. In all treatments, the highest amount of reducing sugar, soluble protein as well as the cellulolytic activities of three enzymes viz. cellobiase, carboxymethyl cellulase and avicelase were obtained at 6th week of fermentation. Compared to raw, unsoaked substrates, soaking treatment alone could produce 10% more soluble protein in both substrates whereas reducing sugar increment was 5% and 6% in jute sticks and jute plants, respectively. From all treatments, combination of soaking and lime treatment in green jute plants yielded higher value than jute sticks in terms of reducing sugar, soluble protein and enzymatic activity. The radiation doses at 20, 30 and 40 kGy appeared to have no effect on sugar and protein accretion. During eight weeks of fermentation, relatively higher cellobiase activity was found compared to that of carboxymethyl cellulase and avicelase. The present investigation indicates that fungal conversion with pretreatment can turn these lignocellulosic agro-wastes to a nutritionally enriched animal feed by increasing the crude protein and reducing sugar content. However, further research is necessary to develop strategies for industrial scale production to overcome the crisis of nutritionally improved animal feed.

    Residual biogas slurries (BGS) of detoxified mahua cake and cow dung were used as supplements to enhance the yield and nutritional quality of Lentinus sajor-caju on wheat straw (WS). Supplementation with 20% BGS gave a maximum yield of 1155 gkg-1 fruit bodies, furnishing an increase of 95.1% over WS control. Significant increase (p ≤ 0.05) in protein content (29.6-38.9%), sugars (29.1-32.3%) and minerals (N, P, K, Fe, Zn) was observed in the fruit bodies. Principle component analysis (PCA) was performed to see the pattern of correlation within a set of observed variables and how these different variables varied in different treatments. PC1 and PC2 represented 90% of total variation in the observed variables. Moisture (%), lignin (%), celluloses (%), and C/N ratio were closely correlated in comparison to Fe, N, and saponins. PCA of amino acids revealed that, PC1 and PC2 represented 74% of total variation in the data set. HPLC confirmed the absence of any saponin residues (characteristic toxins of mahua cake) in fruit bodies and mushroom spent. FTIR studies showed significant degradation of celluloses (22.2-32.4%), hemicelluloses (14.1-23.1%) and lignin (27.4-39.23%) in the spent, along with an increase in nutrition content. The study provided a simple, cost effective approach to improve the yield and nutritional quality of L. sajor-caju by resourceful utilization of BGS.

    Full Text Available Objective: Dental caries, periodontitis and other mucosal diseases are caused by a complex community of microorganisms. This study aimed to investigate the antimicrobial properties of saponins of four important oil yielding medicinal plant extracts on selected oral pathogens that are involved in such diseases.Materials and Methods: Saponins were extracted from Bauhinia purpurea, Madhuca longifolia, Celastrus paniculatus and Semecarpus anacardium and purified. Antimicrobial properties of these saponins against Streptococcus mutans, Streptococcus mitis, Streptococcus salivarius, Staphylococcus aureus and Lactobacillus acidophilus were determined using well diffusion method. The minimum inhibitory concentration (MIC was determined as the lowest concentration of saponins inhibiting bacterial growth after 14 h of incubation at 37°C. The bactericidal activity was evaluated using the viable cell count method.Results: The minimum inhibitory concentration (MIC and minimum bactericidal concentration (MBC of Madhuca longifolia saponin on Streptococcus mutans MTCC 890, Streptococcus mitis and Staphylococcus aureus was 18.3 ± 0.15/34.4 ± 0.24 µg/ml, 19.0 ± 0.05/32.2 ± 0.0 µg/ml and 21.2 ± 0.35/39.0 ± 0.30 µg/ml, respectively and Bauhinia purpurea saponin on Streptococcus mutans MTCC 890, Staphylococcus aureus and Lactobacillus acidophilus was 26.4 ± 0.20/43.0 ± 0.40 µg/ml, 29.0 ± 0.30/39.6 ± 0.12 µg/ml and 20.2 ± 0.05/36.8 ± 0.23 µg/ml, respectively.Conclusion: The strong antimicrobial activity of Madhuca longifolia and Bauhinia purpurea may be due to the presence of complex triterpenoid saponins, oleanane type triterpenoid glycosides or atypical pentacyclic triterpenoid saponin. Hence, these extracted saponins may be used in food and oral products to prevent and control oral diseases.

    Full Text Available Os cogumelos comestíveis Pleurotus sajor-caju apresentam uma delicada consistência, alto teor de umidade e aroma característico, sendo comercializados no varejo, preferencialmente in natura. Sua vida útil pode variar entre 2 a 7 dias, em função da umidade relativa e tmperatura de armazenamento. Neste trabalho, os cogumelos frescos foram imersos durante 2 minutos nas soluções de peróxido de hidrogênio, ácido cítrico e água destilada, drenados, acondicionados em bandejas de poliestireno e embalados em filme plástico. As bandejas foram mantidas sob refrigeração a 4°C e avaliou-se a cor, firmeza e variação de massa dos cogumelos no primeiro, quinto e décimo dia de armazenamento, após os tratamentos. Ocorreram perdas de firmeza e massa, bem como o escurecimento dos cogumelos em todos os tratamentos nas avaliações do quinto e décimo dia. Portanto, os tratamentos utilizados não apresentaram resultados satisfatórios na manutenção da firmeza, cor e massa dos cogumelos Pleurotus sajor-caju in natura nas concentrações utilizadas.The mushrooms Pleurotus sajor-caju are usually avaliable in natura and according to the storage conditions, it's shelf life varies from 3 to 7 days. The objectives of this study were to evaluate the increase of fresh mushrooms'shelf life by immersion into citric acid solution, hydrogen peroxide solutions and distilled water. Fresh mushrooms were immersed in these solutions for 2 minutes, dried, packed in trays and kept under refrigeration (4°C for 10 days. Color, texture and loss mass of the mushrooms were evaluated in the first, fifth and tenth days. A yellowish colour in the mushrooms appeared and their texture and mass decreased. The global aspect of the immersed mushrooms had no difference compared to the control; thus the process of immersion into different solutions did not extend the shelf life of fresh mushrooms.

    Full Text Available Os alimentos e bebidas desenvolvidos atualmente buscam cada vez mais associar sabor agradável com alegações funcionais, oferecendo aos consumidores produtos mais saudáveis. Neste sentido, o objetivo deste trabalho foi desenvolver um néctar de caju adoçado com mel de abelha em substituição à sacarose, estudando também sua estabilidade química, físico-química, sensorial e microbiológica durante 180 dias de armazenamento à temperatura de 28 ± 2 °C. No desenvolvimento do produto avaliaram-se, através de testes afetivos de sabor e aceitação global, quatro formulações (A, B, C e D com diferentes quantidades de suco de caju (15 e 20% associadas a diferentes quantidades de mel em sólidos solúveis (10 e 11 °Brix. A formulação mais aceita foi processada e avaliada após o processamento e a cada 45 dias até o final do período de armazenamento. Dentre as formulações testadas, a preferida pelos provadores foi a formulação D com 20% de suco de caju e 11 °Brix. No estudo de estabilidade o produto manteve boa aceitação sensorial até o final do armazenamento em relação aos atributos: cor, sabor, avaliação global e intenção de compra. O produto manteve padrões microbiológicos satisfatórios de acordo com a legislação durante o armazenamento. As alterações químicas e físico-químicas ocorridas não caracterizaram instabilidade do produto, com exceção da vitamina C que ao final da armazenagem teve um decréscimo acentuado. Trata-se, portanto, de uma alternativa viável ao mercado de bebidas.Food and beverages developed today search the association of pleasant flavor with functional claims, offering consumers healthier products. In this sense, the objective of this work was to develop a ready-to-drink cashew apple juice sweetened with honey in substitution to sucrose and to evaluate its chemical, physicochemical, sensory and microbiological stability during 180 days storage at a temperature of 28 ± 2 °C.

    Full Text Available Traditionally, the cultivation of Pleurotus sajor-caju is performed on different composted and pasteurized agricultural residues. The objective of this study was to investigate whether traditional composting and pasteurization processes could be replaced by washed and supplemented (mineral or organic sugarcane bagasse. In one experiment, fresh sugarcane bagasse was immersed in hot water at 80°C for two hours (control or washed in fresh water for one hour using an adapted machine for residue treatment. In another experiment, fresh sugarcane bagasse was washed in fresh water (control, and supplemented with corn grits (organic supplementation, or supplemented with nutrient solution (mineral supplementation. In the first experiment, the washed bagasse presented a average biological efficiency (ABE of 19.16% with 44% contamination, and the pasteurized bagasse presented a ABE of 13.86% with 70% contamination. In the second experiment, corn grits presented the poorest performance, with a ABE of 15.66% and 60% contamination, while supplementation with the nutrient solution presented a ABE of 30.03%, whereas the control of 26.62%. Washing fresh sugarcane bagasse could suppress the pasteurized substrate in Pleurotus sajor-caju production, compensating a reduced ABE with a faster process.Tradicionalmente, o cultivo do Pleurotus sajor-caju é realizado utilizando-se diversos resíduos agrícolas, precedido dos processos de compostagem e pasteurização. O presente trabalho teve por objetivo comparar o processo de pasteurização com a lavagem do bagaço de cana-de-açúcar e avaliar formas de suplementação do bagaço, visando aumento na produtividade. No primeiro experimento, os colmos da cana-de-açúcar passaram por moenda para a extração do caldo, sendo em seguida desfibrados.

    Full Text Available Les besoins de l'Europe occidentale en propylène utilisé en pétrochimie sont actuellement de 7,4. 10 puissance 6 t/an. Au cours des prochaines années, le taux de progression moyen de la consommation devrait être de l'ordre de 1,8%/an; ainsi en 1995, la pétrochimie européenne utiliserait environ 8,7. 10 puissance 6 t de propylène. L'essentiel de la progression de cette consommation sera dû au fort accroissement de la production de polypropylène et à un degré moindre de l'oxyde de propylène, de l'isopropanol et de l'éthyl-2 hexanol. Par contre les débouchés représentés par l'acrylonitrile et le cumène resteront pratiquement stables. La consommation de propylène dans les productions de butanols devrait diminuer. La part des besoins en propylène satisfaite par les vapocraqueurs européens qui est en 1986 de 82 %, devrait être inférieure à 75 % en 1995. Il sera de plus en plus nécessaire de se tourner vers d'autres sources d'approvisionnement. En 1986 les raffineries européennes ont produit 1,05. 10 puissance 6 t de propylène utilisé en pétrochimie et les importations ont atteint 0,3. 10 puissance 6 t. En 1995 la différence entre la consommation et la production des vapocraqueurs pourrait dépasser 2,0. 10 puissance 6 t. Il semble peu probable que les unités de craquage catalytique puissent combler le déficit sauf si les rendements en propylène augmentent très notablement. On peut s'attendre à la construction de splitters propylène/propane et à une augmentation des importations. D'autre part, en raison de la tension qui risque d'apparaître sur les prix du propylène, l'intérêt de certaines voies de synthèse actuellement considérées comme non rentables pourrait augmenter; ces nouvelles voies sont : - la déshydrogénation du propane déjà considérée dans d'autres régions (Mexique, Indonésie, Malaisie; - la métathèse entre l'éthylène et les butènes-2, pouvant eux-mêmes être produits à partir d

  14. Changes in the chemical composition and in vitro gas production of maize stover degraded with two edible mushrooms: Pleurotus sajor caju and Pleurotus pulmonarius

    International Nuclear Information System (INIS)

    Maize Stover was degraded using two white rot fungi: Pleurotus sajor pulmonarius, in a solid-state fermentation. In vitro gas production of the resulting substrates was carried out in 24h incubation and, the metabolisable energy, organic matter digestibility (OMD) and short chain fatty acid were predicted. The chemical composition and the crude fibre fractions were also determined. The result of the experiment shows that the crude protein (CP) increased from 3.6% in the control (UM) to 12.17% for Pleurotus sajor caju (PSM) and 19.63 for Pleurotus pulmonarius (PPM). This agrees with the report of Farkas. The crude fibre (CF) decreased ( P 0.05) while the rate of gas production (c h-1) was highest in the control (UM ) at 0.31ml/200mg DM. Short chain fatty acid and metabolisable energy were not different (P > 0.05). However, organic matter digestibility increased (P 4) produced also differed significantly. The outcome of this study shows that fungal degradation of maize stover enhanced the crude protein contents while fibre fractions were reduced, this suggest it that it can be used as protein supplement in the diet of ruminants. Further in vivo work is warranted to confirm this. (author)

    Full Text Available Laccase enzymes are now commercially available, and a laccase/mediator combination is currently marketed for indigo dye bleaching in textile manufacturing; replacing traditional chemical-based processes with enzymatic technology reduces the need for effluent treatment. However, an inexpensive source of these enzymes will be needed to enable wider application of this technology. In the present work, the main objective was to increase laccase production by the mushroom Pleurotus sajor-caju strain PS-2001 grown on sucrose derived from sugar cane, one of most economical carbon sources known, by the addition of compounds that are known to affect laccase production. High laccase activities (45-62 U mL-1 were obtained with additions of syringaldazine, benzoic acid, gallic acid, and vanillin. When CuSO4 was used in conjunction with these aromatic compounds, the levels of laccase activity were further improved, reaching 58-80 U mL-1. These laccase activities indicate the potential of this strain as an enzyme producer, which has also been detected in media containing glucose, but with activity lower than that observed with sucrose.

    2012-05-01

    Full Text Available Observations of environmental change by local resource users may be an important source of information about past and current environmental conditions to complement scientific studies and monitoring. In this exploratory, qualitative study, we documented observations of environmental change made by 27 stockmen in the two westernmost valleys of the Central Western Pyrenees of Spain. Pastoralists reported changes in weather, corresponding declines in the flow of mountain springs, and an increase in shrub and tree cover in the mountains. Explanations for the increase in woody plant cover differed in the two valleys; however, the majority of stockmen from both villages believed that the lack of human presence in the mountains contributes to shrub encroachment. Stockmen’s observations of environmental change suggest additional research needs regarding climate and vegetation change in the Pyrenees, and highlight the potential contributions of Pyrenean pastoralists’ local knowledge to environmental monitoring, research and management.Las observaciones sobre el cambio medioambiental realizadas por usuarios locales pueden ser una importante fuente de información sobre las características medioambientales del pasado y del presente para complementar los estudios científicos y el monitoreo.

Resumen cambios climáticos relativos a la disminución del caudal de las fuentes de montaña y al aumento de la cubierta vegetal de matorrales y arbolado en las montañas. Las explicaciones sobre el aumento de arbolado difieren en los dos valles; sin embargo la mayoría de los ganaderos de ambos pueblos pensaban que la falta de presencia humana en las montañas contribuye a la invasión del matorral.

    Full Text Available Not very long after the Discovery, the pearls from the West Indies competed with those from the Orient for the full regalia of the ladies of the gentry, or that of the most revered virgins, while raising the curiosity of the best known chroniclers and creating an excruciating tax system. Considering the legislation passed for the benefit of Indians, those were to a large extent replaced in the “pearl fisheries” by black slaves submitted by the covetousness of their masters and the interests of the Crown to horrendous living and working conditions which most of the time relentlessly led them to death.

    Poco después del Descubrimiento, las perlas de las Indias occidentales rivalizaron con las de Oriente para el adorno de las damas de la alta sociedad o de las Vírgenes más veneradas, suscitando la curiosidad científica de los cronistas más conocidos y una exigente legislación fiscal. Debido a las leyes emitidas a favor de los indios, éstos se sustituyeron en gran parte, en las pesquerías de perlas, por esclavos negros sometidos —por la codicia de los amos y el interés de la Corona— a despiadadas condiciones de vida y de trabajo que desembocaban las más veces en una muerte inexorable.

In ciascun titolo dei loro rispettivi bestseller internazionali (Balzac e la piccola sarta cinese, Leggere Lolita a Teheran, Kafka sulla spiaggia troviamo un ossimoro dello stesso tipo: il  nome di un autore occidentale canonico viene impiegato in un contesto insolito, legato alla geografia del vicino o dell’estremo Oriente. Ne consegue un effetto di straniamento che finisce per ridare forza alla percezione dell’opera letteraria, forse con maggiore decisione di quanto non sia possibile fare oggi in Occidente. Attraverso l’uso (e il rovesciamento del concetto di ‘orientalismo’ di Edward Said e, per Kafka sulla spiaggia, attraverso l’applicazione di principi della teoria di Lacan, lo studio analizza le dinamiche del trasferimento di miti letterari europei nelle culture orientali.

    Full Text Available Cet article s’appuie sur une dizaine de récits de voyages, effectués par des Françaises dans les régions arabo-musulmanes durant la seconde moitié du XIXe siècle. Ils constituent un matériau permettant d’articuler étude sur le genre et l’impérialisme. Le propos concerne particulièrement le rôle des Occidentales dans la construction d’un discours qui accompagne la colonisation et participe de la définition des hiérarchies sociales et/ou raciales. L’analyse comporte deux versants : le premier s’intéresse aux éléments mobilisés dans la production d’une représentation de la femme arabo-musulmane, figure de l’assujettissement et contre-modèle de l’Occidentale ; le second fait retour sur les locutrices elles-mêmes et questionne l’origine de leurs représentations.This article explores how gender and imperialism are articulated in the writings of a number of French women travelers to Eastern and Arab countries in the second half of the 19th century. It argues for the role of these Western women travelers in the construction of a discourse that accompanied the process of colonialism and contributed to the defining of social and/or racial hierarchies. The article begins with an examination of the rhetoric used to produce a representation of the oppressed Arab-Muslim woman, in opposition to that of the Western woman. It then examines the travel writers themselves in an effort to discern the origins of the representations they develop.

Os frutos testados foram: acerola (Malpighia glabra L., caju (Anacardium occidentale L., carambola (Averrhoa carambola L., goiaba (Psidium guajava L., graviola (Annona muricata L., cajá (Spondias mombin L., jambo (Syzygium malaccense L., and umbu (Spondias tuberosa L.. Os parâmetros biológicos foram obtidos colocando larvas recém eclodidas em cada fruto testado. Nos experimentos de aceitação para a oviposição, as moscas foram expostas a dois pedaços das mesmas frutas. A melhor performance foi obtida com goiaba, graviola e carambola. Larvas criadas no caju e na acerola tiveram performance regular. Nenhum adulto emergiu do cajá, jambo ou umbu. As frutas não influenciaram a longevidade dos adultos, fecundidade das fêmeas, ou viabilidade. Goiaba, graviola e acerola foram preferidos para oviposição, seguidos por carambola, jambo, caju e cajá. Oviposição não ocorreu em umbu. Em geral, frutos nos quais houve um melhor desenvolvimento larval, também foram mais aceitos para oviposição.

    Full Text Available Anacardium othonianum Rizz. is a medicinal plant species that is native to the Brazilian savannah. Adult plants are different from other genus members in this ecosystem due to their size, and efforts to locate the plants may lead to their extraction from the savannah and, frequently, plant death. Micropropagation has played a significant role in the propagation and preservation of specimens of several plant species; therefore, this study evaluated the effect of various salt concentrations and culture medium volumes on the in vitro cultivation of A. othonianum Rizz. Trial (I evaluated two culture media (MS and WPM and three salt concentrations (100, 50 and 25% in a completely randomized design. Trial (II evaluated two culture media and salt concentrations, MS (50% and WPM (100%, and five medium volumes (10, 15, 20, 25 and 30 mL per test tube as a 2 x 5 factorial in a completely randomized design. After 30 and 60 days of growth, the percentage of plantlet survival, average plantlet and leaf lengths and the average number of leaves and buds per explant were evaluated. The MS (50 and 25% media and WPM (100 and 50% media were the most effective for plantlet regeneration. The best responses were observed in 15- and 25-mL volumes of the MS (50% medium. Therefore, the use of a 15-mL volume is suggested for greater medium economy.O Anacardium othonianum Rizz. é uma espécie frutífera e medicinal nativa do Cerrado brasileiro. As plantas adultas distinguem-se das demais espécies do gênero existente nesse bioma em função do seu porte arbóreo. Sua exploração ocorre de forma extrativista e muitas vezes em caráter predatório. Sob esse contexto, a micropropagação tem dado significativas contribuições na propagação e preservação de caracteres de interesse em diversas espécies de plantas e, desta forma, o objetivo deste trabalho foi avaliar os efeitos de diferentes concentrações de sais e volumes do meio de cultura no cultivo in vitro de A

Los rasgos reconocidos corresponden a distintos tramos reactivados de las fallas que delimitan los frentes serranos y a estructuras que afectan los depósitos cuaternarios sobre el piedemonte. la sierra de Velasco Oriental se encuentra marginada por fallas de rumbo NNE e inclinación al ONO, mientras que la sierra de Ambato austral presenta estructuras de rumbo NE que inclinan al NO. En el bloque Carrizal estas direcciones se interfieren originando un sector de mayor complejidad estructural. La deformación observada evidencia la persistencia de un régimen compresivo durante el Cuaternario al que se asocian fallas inversas de vergencia oriental a sudoriental. Estas fallas continúan elevando los cordones serranos y constituyen potenciales fuentes sismogénicas.

    Full Text Available Bouteloua vaneedenii is an endemic and extremely rare grass of the West Indies. Very few collections are known, and the most recent collection is from 1922. With the aim of finding the species, a team of Mexican and Cuban agrostologists conducted a field trip and found B. vaneedenii in the same locality where it was collected in 1922 on dry limestone rocks. Although it was stated that B. vaneedenii probably was extinct from Cuba, vigorous populations remain in at least 2 localities in Pastelillo. Further exploration may lead to the discovery of additional populations and the reevaluation of its current conservation status.Bouteloua vaneedenii es un pasto extremadamente raro, nativo de Las Indias Occidentales y del que muy pocas recolectas se conocen hasta ahora, la última se realizó en 1922. Con el objetivo de encontrar la especie, un equipo de agrostólogos mexicanos y cubanos condujeron un viaje de campo en busca de B. vaneedenii , la cual fue hallada en la misma localidad donde se recolectó sobre rocas calizas en 1922, a pesar de que se había señalado como probable extinta para Cuba. Se ubicaron 2 poblaciones en buenas condiciones; no obstante, es necesaria una exploración más intensa confirmar su estado actual de conservación.

    construction of the El Golfo volcano seems to have taken place after a relatively long period of activity, probably coinciding with the maximum development of the Cumbre Nueva rift on La Palma. The initial subaerial activity at El Golfo was characterised by basaltic lavas that evolved to trachybasalts and trachytes, and finally towards more differentiated eruptive episodes indicative of the terminal state of the volcanic activity of the El Golfo volcano. The excessive growth of this volcano triggered the failure of its north flank, generating the spectacular scarp and present El Golfo depression. Subsequent volcanism, from emission vents arranged in a three-armed rift system (rift volcanism, with ages ranging from 145 ka to 2,500 years, with probably prehistoric eruptions, implies the much more moderate continuation of the earlier predominantly basanitic-tephritic volcanic activity. This period may correspond to that of maximum development of the Cumbre Vieja rift, in the island of La Palma.Las Canarias occidentales, relativamente poco estudiadas hasta hace unos años desde el punto de vista geológico, han aportado sin embargo datos decisivos para la comprensión de muchos de los problemas geológicos más importantes del archipiélago, que posiblemente se hubieran dilucidado más prontamente si su estudio se hubiese comenzado, como en la mayoría de las cadenas de islas volcánicas oceánicas, por su extremo más reciente. Como resumen de sus principales rasgos geológicos evolutivos de ambas islas destacamos las siguientes etapas de desarrollo: Durante el Plioceno se levanta en el extremo occidental del Archipiélago, en la isla de La Palma, un edificio o monte submarino constituido por pillow lavas, pillow brechas e hialoclastitas de composición basáltica, intruido por domos traquíticos, plutones de gabros y una densísima red de diques. Por el efecto de la intensa intrusión magmática y filoniana el edificio submarino sufrió un levantamiento hasta cotas de 1.500 m y

    Full Text Available Commercial cashew apple juice is widely accepted in the Brazilian market. Cashew apple has high content of ascorbic acid, an important nutrient to human beings. Ascorbic acid content in food can be affected by processing and storage conditions. Commercial cashew apple juice samples, ready-to-drink and concentrated, were analyzed. The ascorbic acid content, total titratable acidity, total soluble solids, and pH of the juices were determined during storage at 4 °C after the containers were opened. The ascorbic acid content presented a great variability among the samples analyzed ranging from 37.3 to 46.3 mg.100 mL-1 in ready-to-drink juices and from 75.7 to 152 mg.100 mL-1 in concentrated juices. The storage of commercial cashew apple juices for 48 hours at 4 °C resulted in ascorbic acid losses of up to 8.8% for concentrated and 6.4% for ready-to-drink juices. The other parameters remained stable during storage. The results of this study point to the importance of considering ascorbic acid losses in commercial cashew apple juices which occurs after opening but before the expiration date expires.Sucos de caju industrializados são amplamente aceitos no mercado brasileiro. O caju contém alto teor de ácido ascórbico, importante nutriente para o ser humano. O teor deste nutriente pode ser afetado pelo processamento e pelas condições de estocagem dos alimentos. Foram analisadas amostras de sucos industrializados de caju, prontos para o consumo e concentrados. O teor de ácido ascórbico, a acidez total titulável, o teor de sólidos solúveis totais e o pH dos sucos foram determinados durante estocagem a 4 °C, após abertura das embalagens. Houve grande variabilidade no teor de ácido ascórbico entre as amostras, 37,3 a 46,3 mg.100 mL-1 nos sucos prontos para o consumo e 75,7 a 152 mg.100 mL-1 nos sucos concentrados. A estocagem dos sucos por 48 horas a 4 °C resultou em redução do teor de ácido ascórbico em até 8,8% para os concentrados

    Mushroom (P. sajor-caju) was cultivated with rice straw. The rice straw was chopped and ground to investigate the effects of two physical pretreatment methods on mushroom yield and nutrient utilization. It was found that rice straw ground into 2.0 cm produced highest yield of mushroom as compared to the rice straw chopped into 2.0 and 4.0 cm and that ground into 0.5 cm, indicating that appropriately grinding pretreatment of rice straw is an effective method to increase mushroom yield, however, too fine grinding did not increase yield. More C, N, P, K were transported into mushroom body and therefore effectively used in the ground straw than the chopped one, implying improved utilization efficiency of nutrient in the ground straw as a result of grinding pretreatment.%以稻草为基质培养平菇P. sajor-caju,就不同物理预处理方法(切碎和粉碎)、不同处理尺寸对平菇产量和基质营养利用效率的影响进行了试验研究.结果显示,与切碎预处理相比,粉碎处理有利于提高平菇产量和基质营养的利用效率,但过度粉碎效果并不好;当稻草粉碎成2.0 cm时,平菇的产量最高;稻草基质营养的利用效率与产量之间存在对应关系,平菇产量愈高,基质中主要营养成分C、N、P、K的利用效率也就愈高.合适的粉碎预处理是提高平菇产量的简单有效的方法之一.

Los rasgos reconocidos corresponden a distintos tramos reactivados de las fallas que delimitan los frentes serranos y a estructuras que afectan los depósitos cuaternarios sobre el piedemonte. la sierra de Velasco Oriental se encuentra marginada por fallas de rumbo NNE e inclinación al ONO, mientras que la sierra de Ambato austral presenta estructuras de rumbo NE que inclinan al NO. En el bloque Carrizal estas direcciones se interfieren originando un sector de mayor complejidad estructural. La deformación observada evidencia la persistencia de un régimen compresivo durante el Cuaternario al que se asocian fallas inversas de vergencia oriental a sudoriental. Estas fallas continúan elevando los cordones serranos y constituyen potenciales fuentes sismogénicas.Along the eastern front of the Sierra de Velasco and at the southern end of the Sierra de Ambato, western Sierras Pampeanas, have been found new evidences of Quaternary tectonic activity near La Rioja city. Observed evidences correspond to different reactivated sections of the faults that bound the mountain fronts, as well as to structures affecting the Quaternary deposits on the piedmont. The bounding faults of the Sierra de Velasco Oriental-front exhibit a NNE trend and WNW dip, while structures at the southernmost Ambato range are characterized by NE trend and NW dip. The neotectonic faults of the El Carrizal block are the result of the interference of both structural trends, resulting in a sector with higher structural complexity. The here described deformation show the persistence of a compressive regime during the Quaternary, with eastern to southeastern verging reverse faults.

Doze animais foram distribuídos em um ensaio de reversão, com quatro tratamentos: 0, 8, 16 e 24% de castanha no concentrado. As vacas receberam cana-de-açúcar à vontade e sete quilos de concentrado por dia. Maior consumo de matéria seca de cana-de-açúcar foi observado no tratamento com concentrado sem castanha (7,70kgMS/dia em relação aos tratamentos com 16% e 24% de castanha (7,35 e 7,05kgMS/dia, respectivamente.

Animals were raised in the semi-arid region of the Brazilian Northeast. Twelve cows were subjected to a switch back experimental design, with four treatments: 0, 8, 16, and 24% of cashew nut in the concentrate. Each cow received 7kg of concentrate per day and had free access to sugar cane. Dry matter (DM intake and milk yield were daily taken as well as measurements of rectal and milk temperature; and cardiac and respiratory rates. The highest intake of forage (sugar cane was obtained when the concentrate had no cashew nut (7.7kgDM/day. This value was not different when the concentrate contained 8% of cashew nut (7.59kgDM/day but greater than dry matter intake of cows receiving diets with 16% of cashew nut (7.35kgDM/day; P0.05. Such low variability in daily milk yield could be associated with the higher energy density of diets containing more cashew nut. Finally, indicators of heat stress were not influenced by changes in the diets, given the air temperatures and

    Full Text Available Desde el descubrimiento de América y a lo largo de todo el siglo XVI, una de las principales preocupaciones de los cartógrafos fue el dibujo cada vez más preciso de las costas del continente americano y de las islas atlánticas. Los estudios de los mapas de la época suelen concentrarse en los ensayos que los cartógrafos hicieron para diseñar las tierras nuevas, en especial, de América. En ese sentido, el océano Atlántico parecía ser el espacio que se definía por la negativa: aquello que no era tierra y que quedaba entre América y Europa. El Atlántico comenzó a ser objeto de diversas valoraciones simbólicas que fueron relevantes en la reorganización del imaginario geográfico de la época. El Atlántico, lejos de ser un espacio “hueco”, era parte de los territorios nuevos que se estaban conquistando y, así, fue integrado, con sus singularidades, a la nueva imagen del mundo. En este trabajo proponemos explorar los modos en que el Atlántico fue cartografiado en los mapamundis europeos del siglo XVI para analizar las formas en que este océano fue moldeado dentro del imaginario de un mundo geográfico que rápidamente se expandía y transformaba.Since the discovery of America and throughout the sixteenth century, one of the main concerns of cartographers was to draw with increasing precision the coasts of continental America and the Atlantic islands. The study of several maps from that time is included in essays developed by cartographers to outline the new land, especially in the case of America. In this sense, the Atlantic Ocean seemed to be the space defined by the negation of the above: that was not land and which filled up the space between America and Europe. The Atlantic Ocean started to be the object of a number of symbolic valuations which were relevant in the reorganization of the geographical imaginary space of the time. Far from being an “empty” space, the Atlantic Ocean, was part of the new territories being conquered and, as such, was incorporated to the new world’s image, along with its peculiarities. This work proposes to explore the ways in which the Atlantic Ocean was drawn in the European sixteenth century world maps, in order to analyze how this Ocean was molded within the imaginary geographic world which was undergoing a rapid transformation and expansion.

    A study has been made of the semi-synthesis of 1,3-diols (anacardic alcohols) from natural phenolic lipid resources from Anacardium occidentale and Anacardium giganteum which have given C15 and C11 derivatives, respectively. An isomeric 1,3-diol (isoanacardic alcohol) has been obtained from cardanol separated from technical cashew nut-shell liquid. Homologous 1,3-diols have been synthesised from a range of synthetic 2-alkyl-, 3-alkyl- and 4-alkylphenols and from 6-alkylsalicylic acids. The natural 1,2-diol, urushiol, from Rhus vernicifera has been purified. All these lipidic compounds have been studied for their complexation and the potential recovery of boron as boric acid.

    The present study investigates new sources of infusion as an oviposition attractant for Aedes aegypti L. Infusions with fetid and non-fetid odors were compared as an oviposition stimulant. Traps baited with infusions of dehydrated cashew leaves (Anacardium occidentale), potato peels (Solanum tuberosum) and graminea (Panicum maximum) were compared as attractants, and the effect of odor (fetid and unfetid) on attractiveness was tested. Oviposition activity changed significantly according to the concentration and type of infusion (F = 4.1279; gl = 2; P = 0.0231). A larger number of eggs were observed in cups containing 50% A. occidentale (non-fetid odor) and 30% P. maximum (fetid odor). When compared in the same cage, comparable oviposition was found between A. occidentale and P. maximum. Moreover, approximately 20% more eggs were recorded in the infusion without odor when compared to the grass infusion and water. These findings suggest A. occidentale as a new stimulant for use in ovitraps for Aedes surveillance and control, with the benefit of having an agreeable odor. PMID:20498970

    Full Text Available The hide tanners of Brazil Northeast region have in Anadenanthera colubrina (Vell. Brenan var. cebil (Gris. Alts. their only source of tannins. As the activity of exploration is extractiviste without the concern of recovery of explored trees and the absence of other tannin sources, exposes the specie to exhaustion and the tanners and extractivistes family to go bankruptcy. Thus, this work aimed to evaluate the tanin potential of Prosopis juliflora, Anadenanthera colubrina var. cebil, Anacardium occidentale, Mimosa tenuiflora, Mimosa arenosa and Croton sonderianus. These species, Anacardium occidentale, Mimosa arenosa and Mimosa temuiflora showed, respectively, 19.83%, 18.11% and 17.74% of tannins. The Anadenanthera colubrina showed 11.89% and was inferior them mentioned species. The Prosopis juliflora and Croton sonderianus showed 3.02% and 6.62%, respectively. The abundance of Mimosa arenosa and Mimosa tenuiflora in the Brazilian Semi-arid proposes them as potential of tannin production. However, there is need of researches to verify their technical viability for skins, as well as for other uses for tannins.

En el granitoide no deformado (protolito se preservan asociaciones minerales y texturas relícticas, ígneas y metamórficas, que son obliteradas por la deformación. La milonitización operó en un sistema abierto provocando la movilización (ganancia o pérdida de casi todos los elementos mayores y traza, incluyendo las tierras raras e isótopos de Rb/Sr y Sm/Nd. Los cambios químicos fueron controlados mayormente por transporte sintectónico de fluidos y por transformaciones mineralógicas producidas durante la milonitización (disminución del contenido de granate, biotita y minerales accesorios y neoformación de mica blanca en la matriz de las milonitas. Las variaciones isotópicas entre el protolito y las milonitas también serían resultado de la intervención de fluidos durante la deformación, con interacción variable entre fluido y rocas de caja. Los cambios texturales, mineralógicos y químicos experimentados por el granitoide durante la milonitización, permiten reconstruir su evolución tectono-metamórfica y las condiciones metamórficas imperantes.

    Full Text Available Evergreen species of temperate regions are dominant in low-nutrient soils. This feature is attributed to more efficient mechanisms of nutrient economy. Nevertheless, the cashew (Anacardium occidentale- Anacardiaceae, a deciduous species, is native to regions in Brazil with sandy soil, whilst the annatto (Bixa orellana- Bixaceae, classified as an evergreen species native to tropical America, grows spontaneously in regions with more humid soils. Evergreens contain robust leaves that can resist adverse conditions for longer. The physical aspects of the leaves and mechanisms of nutrient economy between the two species were compared, in order to verify whether the deciduous species had more efficient mechanisms that might explain its occurrence in regions of low soil fertility. The mechanisms of nitrogen economy were also compared for the two species at available concentrations of this nutrient. The following were analysed: (i leaf life span, (ii physical leaf characteristics (leaf mass per area, and rupture strain, (iii nitrogenous compounds (nitrogen, chlorophyll, and protein, (iv nitrogen conservation mechanisms (nitrogen resorption efficiency, resorption proficiency, and use efficiency, and (v nitrogen conservation mechanisms under different availability of this mineral. The higher values of leaf mass per area and leaf rupture strain found in A. occidentale were related to its longer leaf life span. A. occidentale showed lower concentrations of nitrogen and protein in the leaves than B. orellana. Under lower nitrogen availability, A. occidentale had higher nitrogen resorption proficiency, nitrogen use efficiency and leaf life span than B. orellana. These characteristics may contribute to the adaptation of this species to sandy soils with low nitrogen content.Perenifólias de clima temperado são dominantes em solos pouco férteis.

    The components of anacardic acid, (a mixture of 6-n-C (15) alkylsalicylic acids whose side chains vary in degrees of unsaturation) have been isolated by high pressure liquid chromatography from a crude extract of cashew nut shell, Anacardium occidentale, and tested for toxicity to fresh water snails, Biomphalaria glabrata. The triene component is the most toxic form (LC (50) 0.35 ppm), the diene and monoene components are less toxic (LC (50) 0.9 and 1.4 ppm), and the saturated component is relatively nontoxic (LC (50) > 5 ppm). Since decarboxylated anacardic acid (cardanol) and salicylic acid do not kill snails at concentrations up to 5 ppm, it appears that both, carboxyl group and unsaturated side chain are absolutely required for molluscicidal activity. The mechanism of toxicity of anacardic acid to snails is unknown. PMID:17402106

    We have theoretically studied new potential candidates of acetylcholinesterase (AChE) inhibitors designed from cardanol, a non-isoprenoid phenolic lipid of cashew Anacardium occidentale nut-shell liquid. The electronic structure calculations of fifteen molecule derivatives from cardanol were performed using B3LYP level with 6-31G, 6-31G(d), and 6-311+G(2d,p) basis functions. For this study we used the following groups: methyl, acetyl, N,N-dimethylcarbamoyl, N,N-dimethylamine, N,N-diethylamine, piperidine, pyrrolidine, and N,N-methylbenzylamine. Among the proposed compounds we identified that the structures with substitution by N,N-dimethycarbamoyl, N,N-dimethylamine, and pyrrolidine groups were better correlated to rivastigmine, and represent possible AChE inhibitors against Alzheimer disease.

    Cardanol is a non-isoprenoic phenolic lipid-mixture of distilled cashew nut shell liquid obtained from Anacardium occidentale. Herein, cardanol is purified from cashew nut shell liquid (CNSL) and synthesized to new compounds with different azo amphiphiles. These synthesized compounds are allowed to self-assembled in hydrophobic environment and checked antifungal activity against Candida albicans. Self-assembled structure of CABA showed higher antifungal activity (16μg/mL) and chitin-binding ability in comparison to CAP and CANB. Furthermore, the self-assembled azo amphiphiles are immobilized with silver ions to prepare hydrogel which showed eight folds enhanced antifungal activity. Toxicity is reduced by several folds of self-assembled or hydrogel structure in comparison to pure compounds. Thus, the self-assembled structure of amphiphiles and their hydrogels have been found to be new macromolecules of interest with potential use as antifungal drugs. PMID:24836571

    BACKGROUND: Cashew (Anacardium occidentale Linnaeus) is the largest agricultural export product in Benin. However, yields and quality are lost due to inefficient pest control. Weaver ants (Oecophylla spp.) may control pests in this crop as they eat and deter pests. In Benin, cashew pest damages......, nut quality and yield were compared among: (i) trees with weaver ant (Oecophylla longinoda Latreille), (ii) trees where weaver ants were fed sugar, (iii) IPM trees with weaver ants combined with GF-120 (a natural insecticide), and (iv) control trees receiving no control measures. RESULTS: Thrips...... damages on nuts were higher than other damage symptoms and significantly lower on control trees compared to other treatments. Percentage of first quality nuts was higher in the control compared to ants treatments, but not different from the IPM-treatment. However, compared to the control treatment, ants...

    Full Text Available Climate variability and change significantly affect smallholder farmers’ food security and livelihoods in sub-Saharan Africa. Tree planting is one of the measures promoted by development programs to mitigate and adapt to climate change. Tree planting is also believed to positively contribute to livelihoods. This paper examines factors influencing smallholders’ tree planting activities in four villages in the Ziro province, Southern Burkina Faso. Furthermore, it analyses the challenges encountered and willingness to continue tree planting under current tenure arrangements. The data was obtained through key informants, household interviews, focus group discussions, and field observations. Results indicate that the majority of farmers interviewed planted Mangifera indica (50%, Anacardium occidentale (32% and Moringa oleifera (30%. In a number of trees planted, Eucalyptus camaldulensis, Mangifera indica and Anacardium occidentale dominated. Tree planters were mainly farmers who held large and old farm areas, were literate and relatively wealthy, had favorable attitudes toward tree planting, and with considerable years of participation in a farmers’ group. The main reasons for planting trees included income generation from the sale of tree products, access to markets and local support for tree planting. Preference for agriculture, tenure insecurity and lack of sufficient land were the main reasons cited for not planting trees. Farm households that were relatively poor, had smaller workforces and smaller farm sizes were not willing to continue tree planting. To effectively engage farmers in tree planting and to make it more attractive, policies are needed that address tenure insecurity for migrants, enable better access to markets, and support fair pricing structures for wood and other tree resources.

    2013-12-01

    Full Text Available Investigation on the pectic substances of cashew (Anacardium occidentale L. apple under different acid-extraction conditions (pH 1.0, 1.5, and 2.0 showed that more than 10%–25% of A. occidentale pectins (AOP could be extracted, depending on the extractant strength. The extracted AOP contained high amounts of galacturonic acid (GalA: 69.9%–84.5% with some neutral sugars of which rhamnose (Rha: 1.3%–2.5%, arabinose (Ara: 2.6%–5.4%, and galactose (Gal: 4.7%–8.6% were the main constituents. The degree of methoxylation (DM was in the range of 28%–46% and was only slightly affected by the extractant strength, thereby indicating isolation of naturally low methoxy pectins (LMP. In terms of gelling capability, AOP yielded firmer Ca2+-mediated LMP gels than commercial citrus LMP with comparable DM. Cashew apple pomace, therefore, appears to be a potentially viable source for possible production of “non-chemically or enzymatically-tailored” LMP.

The majority of the interviewees (85.52% attributed their cure to the use of plants. In the experimental tests, all extracts inhibited the growth of Giardia lambliatrophozoites in different intensities: A. occidentale and P. guajava extracts elicited a moderate activity (250 ≤ IC50 ≤ 500 μg/ml, C. ambrosioides and S. cayennensis extracts evoked a high activity (100 ≤ IC50 ≤ 250 μg/ml, and P. edulis extract showed very high activity (IC50≤ 100 μg/ml. This study shows that an ethnopharmacological approach is useful in the selection of plant materials with potential giardicidal activity.

    Full Text Available Avec les guerres balkaniques, toute la région apprit à connaître un nouveau concept : le nettoyage ethnique. Les États cherchant à homogénéiser leur population le firent de deux manières : par les traités ou par la force. Les statistiques démographiques devinrent ainsi un instrument politique et commença alors « la manipulation ethnique ». Parmi les Chrétiens anatoliens, les Grecs ottomans furent la première cible du CUP qui craignait de perdre « le dernier territoire restant ». Talat Pacha, ministre de l'Intérieur parla aux diplomates allemands de débarrasser le pays « des ennemis de l’intérieur ». Expulsions, terreur et déportations : entre 1912 et 1918, sur les deux rives de l’Égée, près de la moitié des 17,5 millions d’habitants ont été « déplacés ». Le legs le pire de cette période est la tendance des États à croire qu’ils ont le droit d’échanger ou de déporter leurs populations comme du bétail.With the Balkan Wars, the whole region was introduced to a new concept: Ethnic cleansing. States looking to homogenize their population did this in two ways: either by treaty or by force. Population statistics thus became one political instrument and then started the “ethnic engineering”. Among Anatolian Christians, Ottoman Greeks were the first target of the CUP who feared losing the “last remaining territory”. Talat Pasha, Minister of the Interior, talked to German diplomats about ridding the country of “internal enemies”. After expulsions, terrorism and deportations between 1913 and 1918, on both sides of the Aegean, almost half the population of 17.5 million changed places. The era’s worst legacy is the idea that states have a right to exchange or deport their populations like property.

    Full Text Available The remains of the Mayan civilization describe (among other things many observations of various astronomical phenomena observed by the Maya. The modern Celestial Mechanics allows us to calculate with great accuracy when astronomical phenomena occurred and were visible in the sky for a given location on Earth too far back in time. The Maya developed the very accurate calendar known as the Long Count, but when we want to synchronize it with the western one, the correlation between the two is surprisingly very uncertain. The two calendars can be connected each other by analyzing historical data and various astronomical phenomena of which we have a paper trail in the ancient texts that is sufficient to establish an appropriate chronology. The correlation between the Long Count and the Gregorian calendar has been studied by many authors who have obtained correlation values very different from each other (almost 50 different values, which differ from one another by hundreds of years, producing considerable uncertainty in Mayan history in relation to other civilizations. Astronomy can potentially solve the problem of the correct identification of the relationship, provided that the records are available from the observations performed and documented chronologically according to the Mayan Long Count. In the present work has been performed the statistical analysis of the 52 correlations at present known and used pointing out that at the present state of knowledge it is not possible to get the exact determination of the coefficient of synchronization (correlation between the Long Count and the Western calendar, but only an assessment of its probability distribution function, thus allowing you to assign a probability value to each value of the correlation that has been published. The statistical analysis of the 52 values at present known leads to an optimal value of the correlation constant of JDN 588159 with an uncertainty of about ±35 years.

    Full Text Available Le personnage de Salāh al-din Yūsuf, officier kurde au service de Nūr al-dïn devenu maître de l'Égypte puis de Damas et enfin d'Alep, et fondateur de l'empire ayyoubide, a été fort controversé de son vivant avant de devenir pour la postérité « le plus pur des héros de l'Islam ». Pour ses adversaires, les Francs d'Orient, il a de bonne heure suscité leur curiosité, et ceux-ci ont recueilli des informations qu'ils ont utilisées, dès avant 1187, dans un Carmen de Saladino où l'aventurier qu'il était à leurs yeux est présenté sous des traits peu recommandables. Son manque de fidélité envers ses maîtres est particulièrement souligné. Les coups très durs qu'il a portés aux Francs ont été assortis de traits de cruauté ; mais ce sont les manifestations d'un esprit chevaleresque, dont les valeurs étaient communes aux deux camps, qui ont vite retenu l'attention. Le trouvère Ambroise le regarde encore comme un ennemi fort capable de perfidie ; mais le traducteur de Guillaume de Tyr adoucit les remarques du livre qu'il mettait en français pour le rendre plus sympathique. Les textes de caractère épique où il apparaît dans la première moitié du XIIIe siècle (Estoires d'Outremer, Ordene de Chevalerie accentuent ce caractère. Mais c'est dans le second cycle de la croisade qu'on le pare des qualités les plus éminentes qu'on attend d'un chevalier. On lui prête des origines chrétiennes (La fille du comte de Ponthieu et on lui attribue le beau rôle, en insistant sur sa générosité et sur sa bravoure, en lui faisant arbitrer des controverses religieuses, en lui prêtant enfin une aspiration à une mort chrétienne, qui sont bien loin du portrait que faisaient de lui les Francs de la fin du XIIe siècle.

También se calculó la velocidad de subsidencia interválica en función del tiempo geológico. El área en estudio se ubica aproximadamente entre los paralelos 31°17´S y 32°40´S y los meridianos 66°38´W y 67°48´W en las cercanías de la localidad de Marayes, en el sitio denominado cuenca de Las Salinas. Los diagramas tiempo - profundidad permitieron relacionar cambios en la velocidad de subsidencia de la cuenca durante el proceso distensivo del Mesozoico y el actualmente compresional a la cual esta sometida, obteniéndose valores concordantes con áreas circundantes. Como resultado del análisis se encontró que la velocidad de subsidencia inicial fue de 0,0017 mm/año en el Carbonífero, la que fue aumentando lentamente hasta alcanzar los 0,00875 mm/año en el Cretácico. Este incremento disminuye sensiblemente durante el Cretácico superior, para posteriormente incrementarse abruptamente en el Terciario (0,043 mm/año. Este régimen se mantiene durante el Plioceno a Mioceno, alcanzando valores promedios de 0,269 mm/año, culminando con valores de 0,0973 mm/año. De la comparación entre ambos diagramas de subsidencia se observan distintos ritmos de sedimentación entre el sector norte y sur de la cuenca que podría ser la consecuencia de un fallamiento en el basamento. La comparación de estos valores con los obtenidos en la cuenca de Beazley indican que si bien los valores de subsidencia inicial y ritmo de sedimentación fueron similares.

    2011-11-01

    Full Text Available Elsa Morante scholars have long been aware of the author’s profound knowledge of oriental philosophical and literary traditions but, until now, there has been no examination of the theoretical and formal impact of this on her work. It is also well known, as Garboli notes, that during the 1960s and 1970s, Morante was deeply affected by Simone Weil and her work Cahiers, with its summation of oriental spiritualism – especially Hinduism – and Western religious and philosophical traditions. The principle of Weil’s mysticism, of the soul penetrated by grace, of the divine light capable of defeating pesanteur (gravity, is indeed the result of her fusing the Christian doctrine of Divine Illumination – recalling St John of the Cross – with the mystic light of oriental thought. The aim of this paper is, mediating through Weil, to investigate which interpretation of mystical illumination, western or eastern, Morante embraced in the 1960s and ‘70s, and to analyze its impact on her work La Storia (History. According to Weil, the experience of succumbing to divine light is made possible through a meditation on the ordeal of the cross, the unconsoled affliction that strikes the soul and permits the process of ‘decreation’.  Morante’s interpretation of the Second World War and the wounds inflicted by it on humanity, that can only begin to heal through a spiritual process of decreation, can be read in the light of Weil’s philosophy.

    Full Text Available The main topic of the article is to reformulate the concept of Bildung. Reformulation in this sense means analyzing the crisis of Social Sciences and, in consequence, their problematic approach to rationalism, which is strictly orientated to the logos of Natural Sciences, even in the field of normative and symbolic spheres. The analysis focuses upon two aspects: on the one side it discusses the external reasons of the crisis which have led to an increasing reversal of the idea of Bildung. On the other side the analysis takes into consideration the internal reasons (loss of educational/pedagogical theory for this reversal. This double centered investigation offers a revealing insight into the foundation of the educational logos which can not be described as rationalistic logos, but as logos of discourse. In consequence the educational logos requires a semantic reformulation of its main categories and means. The crisis of the foundation of theory of Educational Sciences indicates the general crisis of theory of Social ‘Sciences’, which are no longer aimed at Verstehen (comprehension but at data-based Empirical Sciences addicted to efficiency. The proposal made in this article is to return to reflection about educational thinking, or, in other words: to get away from ‘science’ and return to thinking.

  2. Structures de l'apprentissage dans les pays de l'Europe Occidentale

    Lengrand, Paul

    1982-06-01

    In West European countries, as in most modern societies, learning can be divided into three sectors. Informal education occupies the greatest space, both because of its duration and because it extends into every part of life. It happens in many and various ways and circumstances — from learning the language and socialisation in the family environment to the experiences of retirement and the third age. A large number of factors are involved, particularly married life, family responsibilities, work, the influence of mass media and participation in political activities. It is also the area of self-education. Formal education, dispensed by schools and universities, corrects and guides what is learned in the informal sector. It provides part of the necessary learning in the fields of the arts and of the sciences. However, it falls short so far as the evolution of ideas, morals and social behaviour are concerned. It also only imperfectly fulfils its function of democratization, and because of its concentration on matters intellectual, it does not promote the development of the diverse capacities of the whole person. Nonformal education resembles informal education in that it relates to life, and formal education in its structured character. It is the domain of educational innovation, especially in the context of social relationships. Through the harmonious combination of these three sectors of learning, the principles of a global and integrated lifelong education can be implemented.

    Dans les années 1980-1990, plusieurs expositions ont entrepris de questionner les rapports entre art « occidental » et art « non-occidental ». Chacune des ces tentatives curatoriales revenait sur les relations plus ou moins fantasmées entre ces pratiques artistiques, sans toutefois parvenir à en formuler une version claire. Etrangement, c’est peut-être chez Quatremère de Quincy (1755-1849) que se trouve la clef du rapport mis à l’épreuve par ces récentes présentations.

    Full Text Available AbstractNihilism coincides with the accomplishment of metaphysics which, in turn, culminates in the triumph of the scientific rationality. The essence of metaphysics, in its last accomplishment (nihilism, consists of the oblivion of being, while the essence of nihilism represents the awareness of that oblivious accomplishment. The shadow of the Being (Seiende covers the Being (Sein while the real facts lead the scientific-experimental thought determining, from Galileo on, the supremacy of the experimentally reproducible objectivity as well as of the scientific method on the actually productive subjectivity. The result is the so-called «technological planetary orientation»: lost the sense of the metaphysic question, philosophy comes to the end. In other words, after Nietzsche there is only science/technique. Therefore, how has all that weighed on the aesthetic dimension? The artistic productivity, though reflecting the torment of the human soul, towards the nothing of sensemiraculously tends to make the light of the Being (Sein appear from the shadow of the material Being (Seiende. Every originating artistic shine of the Being (Seinis an aesthetic expression from the pure creative human act which celebrates its own being as a dynamic bond of connections (inter-essewould say evocatively Kierkegaard-Climacus that cannot understand the origin but spread its form. Der Nihilismus entspricht der Erfüllung der Metaphysik, die wiederum im Triumph der wissenschaftlichen Rationalität.

Mit anderen Worten, nach Nietzsche gibt es nur Wissenschaft/Technik. Nun, wie hat all dies die ästhetische Dimension beeinflusst?

    Full Text Available Vermicomposting is a green technology for the purpose of nutrient enrichment from a variety of organic waste products. In this study, saw dust-based spent mushroom compost (SMC, an organic waste and biomass residue, was used as a medium for the cultivation of pea sprouts. After harvesting the pea sprouts, the growth medium was reused to culture earthworms, Lumbricus rubellus. The culturing activity was conducted for 50 days without any pre-composting or thermocomposting. Thus duration of vermicomposting process was shortened as opposed to previous work on vermicomposting of saw dust-based SMC (no amendment for 70 days. The culturing treatments were conducted in triplicate, including one treatment without earthworms as the control. The analysis showed that concentrations of macronutrients in vermicompost were higher compared to controls, in which N = 4.12%, P = 2.07% and K = 1.56%. The C:N ratio was 11.77, which indicates a stabilisation and maturity of the organic waste compost, compared with the C:N ratio for the control, which was 59.34. At the end of the experiment, increment of total biomass and number of earthworms were observed and no mortality was recorded. The results suggested that vermicomposting could be used as an environmentally valuable technology to convert saw dust used for mushroom and pea sprouts cultivation into vermicompost or bio-fertiliser by employing L. rubellus.

    Full Text Available During the dry and rainy seasons, determinations of stomatal resistance and transpiration of five tropical crops were carried out: guarana (Paullinia cupana Kunth, coffee (Coffea arabica L., cashew (Anacardium occidentale L., guava (Psidium guajava L. and rubber (Hevea brasiliensis Muell. - Arg. trees. Experimental design was done at randomized complete blocks with five replications. During the dry season there was a decrease in values of stomatal resistance in the following order: guarana > coffee> cashew> guava > rubber, with values from 2.5 to 30.0 s.cm-1. During the rainy season the stomatal resistance values varied from 1.5 to 3.0 s.cm-1. The guarana and coffee crops showed higher resistance to water transpiration when compared to other crops. During the rainy season, the rubber tree continued to present lower stomatal resistance and, consequently, higher transpiration.O experimento foi realizado no Departamento de Produção Vegetal da Escola Superior de Agricultura "Luiz de Queiroz", ESALQ/USP, Piracicaba, São Paulo, Brasil, utilizando-se as culturas de guaranazeiro (Paullinia cupana Kunth, cafeeiro (Coffea arabica L., cajueiro (Anacardium occidentale L., goiabeira (Psidium guajava L. e seringueira (Hevea brasiliensis Muell. - Arg..

Si l’on envisage la dimension politique du geste originaire de l’anthropologie historique, on constate que c’est un effort pour rendre l’histoire aux démunis de l’histoire, aux prétendus « sans histoire ». Comme pour Levi Strauss, faire de l’anthropologie, pour les historiens, c’était participer à l'effort de décolonisation et le faire porter sur les sciences sociales.One wonders why Jacques Le Goff has used the term anthropology instead of ethnology or ethno-history which could equally reflect his intellectual approach.

    Full Text Available Abstract – Over the last few years, the issue of professional ethics has received much attention in the field of interpreting and translation, and in particular in the field of Community Interpreting (CI or Public Service Interpreting (PSI. (In this chapter we will refer to CI or PSI in Italian as ‘Mediazione Linguistica’. Today, ‘ethics’ figures prominently in the literature, in international conferences, in interpreting courses, in translation/interpreting mailing lists as well as in the working lives of professional interpreters. As an object of theoretical inquiry (meta-ethics as well as a guide for human conduct (normative ethics, ethics has been a prime focus of Western moral philosophy since the time of the Ancient Greeks. This chapter situates the main ethical tenets of the CI/PSI interpreting profession within the framework of the main principles of moral philosophy, namely notions of ‘good’, ‘virtue’, ‘duty’, ‘responsibility’, ‘utility’ and ‘consequence of actions’. The three principal ethical tenets of CI/PSI discussed in this chapter, Accuracy, Impartiality and Confidentiality, were identified on the basis of a general literature review and more specifically from a variegated (and to some degree representative sample of CI/PSI Codes of Ethics. The chapter argues that there is an underlying connection between the principal tenets of moral philosophy and those of the interpreting profession (which mirror similar ethical principles in other professions. The tenet of Accuracy could be seen as a ‘contract’ between interpreter and client, interpreter and source, interpreter and text/translation process/profession. The chapter situates the interpreter’s sense of duty and responsibility towards this tenet at an individual and collective level, within the Kantian tradition of Duty. The other two tenets – impartiality and confidentiality – safeguard the interpreter’s conduct towards the source (author/speaker, professional community and institution as well as towards the receiver (reader/listener.

    Anacardium occidentale belongs to the family Anacardiaceae and is principally grown in tropical America (Mexico, Peru, Brazil, etc.) and India. Cashew nuts contain low amounts of hydroxy alkyl phenols that come from an oily liquid present in their shell and that is known as cashew-nut shell liquid. This paper reports the alkyl phenols composition of cold pressed raw and roasted cashew nut oil. First of all, cashew nut shell liquid was used for a basic fractionation of the alkyl phenol classes by preparative TLC and definitively identified by GC-MS and GC-FID. Anacardic acids were the major alkylphenols contained in both oils followed by cardol, cardanol and 2-methylcardol compounds, respectively. Raw and roasted oils did not show different compositions except for cardanols. The oil produced from roasted cashew nut reported a higher concentration of cardanols. Furthermore, tocopherols and other minor polar compounds were determined by HPLC-FLD and HPLC-DAD-MS, respectively. Tocopherol content varied in a range of 171.48-29.56mg/100g from raw to roasted cashew nut oil, being β-tocopherol the one which presented a higher decrease (93.68%). Also minor polar compounds in cashew oil decreased after roasting from 346.52 to 262.83mg/kg. PMID:20961547

    This tutorial review could serve as an introduction of cardanol into the world of soft nanomaterials; it is a biobased lipid-mixture obtained from the plant Anacardium occidentale L. Cardanol is a renewable raw material derived from a byproduct of cashew nut processing industry: Cashew Nut Shell Liquid (CNSL). Cardanol is a rich mixture of non-isoprenoic phenolic compounds that is a valuable raw material for generating a variety of soft nanomaterials such as nanotubes, nanofibers, gels and surfactants. These nanostructures may then serve as templates for the synthesis of additional nanomaterials. The wealth and diversity of cardanol-derived functional nanomaterials has urged us to present an article that will give readers a taste of a new class of cardanol-derived functional amphiphiles, along with their ability to generate hierarchical functional nanomaterials through non-covalent soft-chemical routes. In this concise review, we discuss selected examples of novel biobased surfactants, glycolipids, and polymers derived from cardanol, and their subsequent self-assembly into functional soft materials.

    Full Text Available In Caravelas, located in southern Bahia state, the main vegetation formations are the mangrove forests and ‘restingas’ (sandbanks presenting, the latter, a high degree of degradation. The aim of this paper is to describe the main forest species of these ‘restingas’ and their direct uses associated with the recovery and management of degraded areas and creation of jobs and income, making thus an important tool for integrated coastal zone. For this, elaborate floral listings and field visits were necessary for recognizing the environment. In the selection of species, a literature about the use, management and value of each species were used, and from there, four species with potential for generating jobs and income along of this proposal were recognized: Mangaba ( Hancornia speciosa , Pitanga ( Eugenia uniflora , Mangaba ( Anacardium occidentale and Aroeira ( Schinus terebinthifolius . The first three are associated with the use of its fruit food, serving these ‘aroeiras’ as pepper trees, with a high value on the world market, and cashew, because of its fertile structure. The identification of products provided sustainable use of species and environment and the Non-Timber Forest Products can be strategic in coastal management, making it an instrument to subsidize social inclusion through the creation of jobs and income, under the movement of Social Technology, contributing to reduce the social vulnerability of traditional coastal communities.

Data were processed using principal component analysis (PCA) and hierarchical cluster analysis (HCA). Antioxidant capacity was measured by DPPH and FRAP assays, which showed significant (P < 0.01) correlation with total phenolic compounds (r = 0.88 and 0.70, respectively), total flavonoids (r = 0.63 and 0.81, respectively), and total monomeric anthocyanins (r = 0.59 and 0.73, respectively). PCA explained 74.82% of total variance of data, and the separation into 3 groups in a scatter plot was verified. Three clusters also suggested by HCA, corroborated with PCA, in which cluster 3 was formed by strawberry, red fruits, blackberry, açaí, and grape pulps. This cluster showed the highest contents of total phenolic compounds, total flavonoids, and antioxidant activity. PMID:24547813

    Full Text Available Massive seasonal invasion by the litter-dwelling beetle Luprops tristis, into residential buildings prior to monsoon rains, and their prolonged state of dormancy render them a very serious nuisance pest in rubber plantations in the Western Ghats in southern India. Feeding preferences of L. tristis towards leaf litter of seven trees co-occurring in rubber plantations, cashew (Anacardium occidentale, mango (Mangifera indica, jackfruit (Artocarpus heterophyllus, wild jack (Artocarpus hirsutus, cocoa (Theobroma cacao, cassia (Cassia fistula, sapota (Manilkara zapota and rubber (Hevea brasiliensis were analyzed with no-choice and multiple-choice leaf disc tests. Results showed that L. tristis is a generalist feeder with a defined pattern of preference, with the leaf litter of rubber being the most preferred followed by those of jackfruit and cocoa. Tender leaves were preferred over mature leaves except for cocoa and sapota. Equal preference towards tender and mature cocoa leaves, presence of patches of cocoa plantations and the scarce distribution of other host plants in rubber plantation belts leads to the proposal that in the absence of tender and mature rubber leaves, cocoa becomes the major host plant of L. tristis.

    Full Text Available Summary: Results of an ethnobotanical study of wound healing treatments among the tribal people of Tirunelveli hills in southern India are presented. A total of 46 plants belonging to 44 genera and 26 families have been documented for their therapeutic use against wounds and related injuries such as cuts, burns, bruises caused by external injury, boils, sores, abscess and wounds created during delivery. Leaves were the most frequently utilized plant part and most herbal remedies are prepared as paste and applied externally; in some cases medicinal preparations were also administered orally. Of the plants collected in the present study none of the plants have been reported to have such specific wound healing compounds except Areca catechu and Scoparia dulcis. The present study suggested that further clinical experimentation is needed to scientifically evaluate these widely used herbal remedies for possible bioactive effects. Industrial Relevance: The study of ethnomedical systems and herbal medicines as therapeutic agents of a paramount importance in addressing health problems of traditional communities and third world countries as well as industrialized societies. Of the reported plants,  Acalypha indica, Anacardium occidentale, Areca catechu, Calotropis gigantea, Cissampelos pareira, Cleome viscosa, Eupatorium odoratum, Euphorbia hirta, Ficus racemosa, Ixora coccinia, Morinda pubescens, Opuntia dillenii, Pongamia pinnata, Scoparia dulcis and Vitex altissima were studied in animal models for wound healing, analgesic and anti-inflammatory activity on the basis of their use in traditional medicine as wound healers and these plants can be used to formulate drugs in pharmaceutical companies.

    The biogenic volatile organic compound (BVOC) composition of ambient air at a rural field site near Djougou, Benin has been studied as part of the AMMA (African Monsoon Multidisciplinary Analysis) project. Ambient air was sampled during day and night during the period 2 June 2006 to 13 June 2006. Gas samples from within the forest canopy and from branch and cuvette enclosure systems for four vegetation species were also obtained and emissions flux estimates made. All samples were analysed for the presence of isoprene, monoterpenes and sesquiterpenes by either gas chromatography-time of flight mass spectrometry (GC-TOF/MS) or comprehensive gas chromatography-time of flight mass spectrometry (GCxGC-TOF/MS). Concentrations of isoprene ranged from a few tens of pptV to in excess of 3000 pptV. Similar concentration ranges for certain monoterpenes were also observed. Limonene was seen at a maximum concentration in ambient air of 5000 pptV. The combination of leaf-level observations and direct analysis of dried vegetation samples suggest that emissions of terpene species from indigenous species are unlikely to account for the unexpectedly high ambient concentrations of monoterpenes. Leaf scale emission measurements and biological sample analysis indicated that Anacardium occidentale, a non-native crop species found throughout the tropics, was the dominant source of monoterpenes at this location. These preliminary findings suggest that activities involving species replacement have potential implications for the chemistry of the African troposphere that have not been widely considered previously.

    Full Text Available The influence of electromagnetic field wave on the survival of spoilage fungi associated with some edible fruits consumed in southwestern, Nigeria was studied using cashew (Anacardium occidentale L., pineapple (Ananas comosus, carrot (Daucus carota, cucumber (Cucumis sativus, apple (Malus domestica and African star apple (Chrysophyllum africanum. The spoilage fungi used include the genera of Aspergillus, Penicillium, Articulospora, Mucor, Staphylotrichum, Bisbyopeltis, Fusarium, Rhizopus and a yeast, Saccharomyces cerevisiae. There was a general decrease in fungal growth as shown in the number of spores produced with increase in exposure time of isolates to electromagnetic field except in Articulospora inflata, Penicillium italicum and Mucor mucedo where there was stimulatory effect as there was increase in the fungal spores compared to the control. A decrease was also observed in growth of the fungal isolates with increase in the intensity of the electromagnetic field at voltage of 7 V to 10 V and from 10 V to 13 V. The highest percentage reduction was recorded by Bisbyopeltis phoebesii at intensity of voltage 13V after 60 minutes of exposure. Exposure of the fruits to electromagnetic field wave did not alter the nutrient components of the fruits as observed in the proximate and mineral contents of the treated and untreated fruits. The result of the study revealed that electromagnetic field wave has great potential for use in the control of fruits spoilage and food preservation.

    A total of 19 Brazilian frozen pulps from the following fruits: açai (Euterpe oleracea), blackberry (Rubus sp.), cajá (Spondias mombin), cashew (Anacardium occidentale), cocoa (Theobroma cacao), coconut (Cocos nucifera), grape (Vitis sp.), graviola (Annona muricata), guava (Psidium guajava), papaya (Carica papaya), peach (Prunus persica), pineapple (Ananas comosus), pineapple and mint (A. comosus and Mentha spicata), red fruits (Rubus sp. and Fragaria sp.), seriguela (Spondias purpurea), strawberry (Fragaria sp.), tamarind (Tamarindus indica), umbu (Spondias tuberosa), and yellow passion fruit (Passiflora edulis) were analyzed in terms of chromaticity, phenolic compounds, carotenoids, and in vitro antioxidant activity using ferric reducing antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays. Data were processed using principal component analysis (PCA) and hierarchical cluster analysis (HCA). Antioxidant capacity was measured by DPPH and FRAP assays, which showed significant (P < 0.01) correlation with total phenolic compounds (r = 0.88 and 0.70, respectively), total flavonoids (r = 0.63 and 0.81, respectively), and total monomeric anthocyanins (r = 0.59 and 0.73, respectively). PCA explained 74.82% of total variance of data, and the separation into 3 groups in a scatter plot was verified. Three clusters also suggested by HCA, corroborated with PCA, in which cluster 3 was formed by strawberry, red fruits, blackberry, açaí, and grape pulps. This cluster showed the highest contents of total phenolic compounds, total flavonoids, and antioxidant activity.

    Full Text Available Context: Our survey was performed near Iquitos (Peruvian Amazon and its surroundings and leads us to consider Mestizo ethnomedical practices. The plant species reported here are traditionally used for ailments related to microbial infections. Inhabitants of various ethnic origins were interviewed, and 52 selected plants extracts were evaluated for their antimicrobial properties against a panel of 36 sensitive and multi-resistant bacteria or yeast. The study aimed at providing information on antimicrobial plant extract activities and the ethnomedical context of Mestizo riverine populations from Loreto (Peru. Material and Method: The minimum inhibitory concentrations (MICs of the plant crude extracts were carried out using the agar dilution method and ranged between 0.075 and 5.0 mg/ml. Results: Of the 40 plants analyzed, 9 species showed MIC ≤0.3 mg/ml (Anacardium occidentale, Couroupita guianensis, Croton lechleri, Davilla rugosa, Erythrina amazonica, Jacaranda copaia subsp. Spectabilis, Oenocarpus bataua, Peperomia macrostachya, and Phyllanthus urinaria for one or several of the 36 microorganisms and only 6 drug extracts were inactive. Among the 40 plants, 13 were evaluated for the first time for an antibacterial activity. Conclusion: This evaluation of the antimicrobial activity of 40 plants using an approved standard methodology allowed comparing those activities against various microbes to establish antimicrobial spectra of standardized plant extracts, and give support to the traditional use of these plants. It may also help discovering new chemical classes of antimicrobial agents that could serve against multi-resistant bacteria.

    Full Text Available During the last decades, agricultural land-uses in West Africa were marked by dramatic shifts in the coverage of individual crops. Nowadays, cashew (Anacardium occidentale L. is one of the most export-oriented horticulture crops, notably in Guinea-Bissau. Relying heavily on agriculture to increase their income, developing countries have been following a strong trend of moving on from traditional farming systems towards commercial production. Emerging infectious diseases, driven either by adaptation to local conditions or inadvertent importation of plant pathogens, are able to cause tremendous cashew production losses, with economic and social impact of which, in developing countries is often underestimated. Presently, plant genomics with metagenomics as an emergent tool, presents an enormous potential to better characterize diseases by providing extensive knowledge on plant pathogens at a large scale. In this perspective, we address metagenomics as a promising genomic tool to identify cashew fungal associated diseases as well as to discriminate the causal pathogens, aiming at obtaining tools to help design effective strategies for disease control and thus promote the sustainable production of cashew in West African region.

    Full Text Available Traditional herbal medicine is a global phenomenon especially in the resource poor economy where only the very rich can access orthodox care. These herbal products are associated with complications such as acute renal failure and liver damage with a high incidence of mortalities and morbidities. Acute renal failure from the use of herbal remedies is said to account for about 30–35% of all cases of acute renal failure in Africa. Most of the herbal medications are not usually identified, but some common preparation often used in Nigeria includes “holy water” green water leaves, bark of Mangifera indica (mango, shoot of Anacardium occidentale (cashew, Carica papaya (paw-paw leaves, lime water, Solanum erianthum (Potato tree, and Azadirachta indica (Neem trees. We report a rare case of a young man who developed acute renal failure two days after ingestion of Chinese herb for “body cleansing” and general wellbeing. He had 4 sessions of haemodialysis and recovered kidney function fully after 18 days of admission.

Este estudo teve como objetivo caracterizar isolados de L. theobromae associados a frutíferas tropicais na região nordeste, considerando os aspectos cultural, morfológico e patogênico. Foram avaliados o crescimento micelial, coloração da colônia, dimensões dos conídios e patogenicidade dos isolados em mudas de cajazeira (Spondia mombin L., cajueiro (Anacardium occidentale L., gravioleira (Annona muricata L. e umbuzeiro (Spondias tuberosa Arruda. Os dados de caracterização morfológica e cultural revelaram diversidade na população do patógeno. Alta variabilidade patogênica foi também detectada, embora não tenha sido possível observar especificidade patogênica em cajueiro. O umbuzeiro apresentou maior resistência relativa ao fungo. Os dados demonstraram também uma interação entre as características morfo-culturais e a patogenicidade dos isolados de L. theobromae.

    Twelve plants used for the traditional treatment of diabetes mellitus in northern Europe were studied using normal and streptozotocin diabetic mice to evaluate effects on glucose homeostasis. The plants were administered in the diet (6.25% by weight) and/or as decoctions or infusions in place of drinking water, to coincide with the traditional method of preparation. Treatment for 28 days with preparations of burdock (Arctium lappa), cashew (Anacardium occidentale), dandelion (Taraxacum officinale), elder (Sambucus nigra), fenugreek (Trigonella foenum-graecum), guayusa (Ilex guayusa), hop (Humulus lupulus), nettle (Urtica dioica), cultivated mushroom (Agaricus bisporus), periwinkle (Catharanthus roseus), sage (Salvia officinale), and wild carrot (Daucus carrota) did not affect the parameters of glucose homeostasis examined in normal mice (basal plasma glucose and insulin, glucose tolerance, insulin-induced hypoglycaemia and glycated haemoglobin). After administration of streptozotocin (200 mg/kg) burdock and nettle aggravated the diabetic condition, while cashew, dandelion, elder, fenugreek, hop, periwinkle, sage and wild carrot did not significantly affect the parameters of glucose homeostasis studied (basal glucose and insulin, insulin-induced hypoglycaemia, glycated haemoglobin and pancreatic insulin concentration). Guayusa and mushroom retarded the development of hyperglycaemia in streptozotocin diabetes and reduced the hyperphagia, polydipsia, body weight loss, and glycated haemoglobin. Mushroom also countered the initial reduction in plasma insulin and the reduction in pancreatic insulin concentration, and improved the hypoglycaemic effect of exogenous insulin. These studies suggest the presence of potentially useful antidiabetic agents in guayusa and mushroom. PMID:2743711

O experimento foi conduzido entre setembro de 2006 e agosto de 2007, na estação experimental da Embrapa Agroindústria Tropical, localizada no município de Paraipaba, Ceará. As variáveis A, g s, E e Ci/Ce foram afetadas apenas em função da época do ano e dos tipos de folhas. A maior influência nos fatores fisiológicos analisados ocorreu devido às condições em que as folhas estavam submetidas (sol ou sombra e aos fatores meteorológicos e não à supressão da irrigação. Isto, possivelmente porque os resultados aqui obtido estejam mais bem relacionados com as fases fenológicas da cultura do que com os tratamentos, demonstrando assim o conspícuo efeito fisiológico da força dos drenos e da irradiância nessas plantas.In this experiment we analyzed the seasonal variations in gas exchange rates of dwarf cashew (Anacardium occidentale L. when exposed to irrigated and rainfed conditions.

Os resultados revelaram que dentre os extratos testados 50% deles apresentaram atividade frente à cepa de S. aureus ATCC 25923. Os extratos ativos foram cajueiro, barbatimão e aroeira. Os demais extratos não apresentaram atividade antimicrobiana frente às cepas em estudo. Quando se avaliou a ação interativa entre os extratos ativos, observou-se interferência antagônica, constatada pela redução dos diâmetros dos halo de inibição de crescimento bacteriano nas associações com os extratos de cajueiro/barbatimão, cajueiro/aroeira e barbatimão/aroeira. De modo que, o uso concomitante extratos vegetais merece um olhar muito cuidadoso pela possibilidade de ocorrer interferências entre eles, reduzindo a potência da atividade antimicrobiana, em relação a sua potência quando utilizados isoladamente.Palavras-chave: Plantas medicinais.

    Full Text Available Com o objetivo de se avaliar os efeitos e mecanismos iniciais da ação da salinidade sobre a redução de NO-3 e a acumulação de solutos nitrogenados, plantas de cajueiro (Anacardium occidentale L., CCP - 1001, com 42 dias de idade foram cultivadas em solução nutritiva contendo 100 mmol L-1 de NaCl, durante 8 dias, em casa de vegetação. A transpiração foi o principal fator de regulação da atividade de redutase de NO-3 (RN que foi fortemente reduzida nas folhas. Contrariamente, a atividade de glutamina sintetase (GS aumentou nas folhas em resposta à salinidade. Esta tendência de aumento da atividade de GS nas folhas foi acompanhada pelas concentrações de aminoácidos solúveis totais, particularmente prolina e proteínas solúveis totais. Por outro lado, o aumento nas concentrações das frações orgânicas de N, nas folhas, foi seguido por decréscimos nas concentrações de clorofilas e por acréscimos nas concentrações de NH+4 . É provável que o aumento da atividade de GS nas folhas de plantas de cajueiro, tenha sido induzido por um adicional suprimento de NH+4 e glutamato, a partir do catabolismo de aminoácidos e de proteínas e por aumentos na atividade fotorrespiratória.To evaluate the effects and initial-action mechanism of salinity on NO-3 reduction and N compounds accumulation, 42-day-old Anacardium occidentale (CCP-1001 plants were hydroponically grown in 100 mmol L-1 NaCl for 8 days (short-term experiment, in greenhouse. The results show that reduction in transpiration rates due to salinity had a relevant role in the regulation of NO-3 reductase (NR activity, which decreased considerably in leaf. On the contrary, glutamine sintetase (GS activity increased in leaf due to salinity. The increase in activity of GS in leaf was followed by the soluble amino acids concentration, in particular proline, and by the total soluble proteins content as well. On the other hand, increase in concentration of organic N fractions in

    Full Text Available Helopeltis theivora Waterhouse, pest of tea, is emerging as a commonly occurring major pest of cashew (Anacardium occidentale L. in recent times. The field observation revealed Chromolaena odorata (L. R.M. King & H. Rob. weed support as an alternate host of this pest during off season of cashew. Biology of H. theivora on this weed was studied for the first time. The incubation period of eggs was 10.5 ± 1.2 d. The 1st, 2nd, 3rd, 4th and 5th nymphal instar developmental times were 36.11 ± 9.52, 43.29 ± 7.35, 27.15 ± 8.41, 41.31 ± 10.13, and 73.91 ± 5.67 h, respectively. Survival percentage of eggs was lower (60.53% than nymphal instars. Adult females and males lived for 22.6 ± 3.29 and 11.8 ± 1.64 d, respectively. Females showed dynamic patterns of fecundity with the number of eggs laid per female ranging 19 to 34. Longevity and fecundity of H. theivora on this weed were significantly lesser when compared on cashew. Egg parasitoids viz., Telenomus sp., Chaetostricha sp. and Erythmelus helopeltidis Gahan were recorded from H. theivora eggs on C. odorata for the first time. For better management decisions, it is important to know about this mirid biology, particularly their life cycle on their alternate hosts so that the right assessment can be made before taking up spray.

    Full Text Available The cashew production is one of the most important agricultural activities from the social-economical viewpoint for the North East of Brazil; besides to produce a great deal of hand labor, it is very important as an exporting commodity. The inadequate use of irrigation in the semi arid regions of the North East of Brazil has induced soil salinization and consequently problems for the irrigated agriculture. In spite of this, few works have been conducted to study the effect of saline stress on the growth and development of the cashew. Because of the lack of information for this crop, an experiment was conducted to study the effect of salinity stress on the phytomass production and nutrient accumulation on the different organs of the precocious dwarf cashew (Anacardium occidentale L. clone CCP76. The study was conducted under controlled conditions using as statistical scheme a randomized block design factorial with six replicates. Five salinity treatments were considered for the irrigation water (electrical conductivities of 0.8, 1.6, 2.4, 3.2 and 4.0 dS m-1 at 25oC. The increasing in salinity of the irrigation water reduced the phytomass at different organs of the studied plant. The nitrogen, phosphorus, potassium, chloride and sodium in the plant varied with the salinity of the irrigation water according with the part of the plant analyzed; in some parts increased, in others decreased, in others increased initially and decreased afterwards, and finally, in other part of the plant the salinity of the irrigation water did not affect the nutrient concentration.

    Full Text Available This study evaluated the physicochemical properties and protein and mineral content of honey samples from Ceará State, Northeastern Brazil, one of the major honey exporters in the country. Nutritional importance of the minerals detected was also analyzed. Physicochemical properties were examined according to the AOAC and CAC official methods; the protein content was determined using the Bradford method, and the minerals were analyzed by atomic absorption spectrometry. All analyses were performed in triplicate. The levels of macrominerals sodium (Na, potassium (K, calcium (Ca, and magnesium (Mg varied from 1.80-47.20, 21.30-1513.30, 14.58-304.82, and 2.48-28.33 mg/kg, respectively, and the trace elements iron (Fe, copper (Cu, manganese (Mn, zinc (Zn, selenium (Se, and chromium (Cr varied from 0.12-8.76, 0.07-1.29, 0.06-1.96, 0.07-1.85 mg/kg, 0.36 × 10-3-62.00 × 10-3 and 22.50 × 10-3-170.33 × 10-3 µg/kg, respectively. Myracrodruon urundeuva honey sample had high contents of macrominerals (Na, K, Ca, and Mg. Protein content of the Anacardium occidentale honey sample was the highest (1121.00 µg/g among the samples analyzed. Among the minerals detected in the honey samples, K showed the highest concentration, followed by Ca, Na, and Mg. The presence of trace elements can show environmental contamination. The honey samples studied were free of trace elements contamination, except for Mn; the Piptadenia moniliformis was the only honey sample that was in compliance with the law requirements. The variations of the chemical constituents in the honey samples are probably related to differences in the floral origin and mineral and protein contents and confirm the nutritional importance of Ceará State honey.

    Full Text Available Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann (Diptera, Tephritidae. Studies on Ceratitis capitata, a world fruit pest, can aid the implementation of control programs by determining the plants with higher vulnerability to attacks and plants able to sustain their population in areas of fly distribution. The objective of the present study was to evaluate the influence of eight tropical fruits on the following biological and behavioral parameters of C. capitata: emergence percentage, life cycle duration, adult size, egg production, longevity, fecundity, egg viability, and oviposition acceptance. The fruits tested were: acerola (Malpighia glabra L., cashew (Anacardium occidentale L., star fruit (Averrhoa carambola L., guava (Psidium guajava L., soursop (Annona muricata L., yellow mombin (Spondias mombin L., Malay apple (Syzygium malaccense L., and umbu (Spondias tuberosa L.. The biological parameters were obtained by rearing the recently hatched larvae on each of the fruit kinds. Acceptance of fruits for oviposition experiment was assessed using no-choice tests, as couples were exposed to two pieces of the same fruit. The best performances were obtained with guava, soursop, and star fruit. Larvae reared on cashew and acerola fruits had regular performances. No adults emerged from yellow mombin, Malay apple, or umbu. Fruit species did not affect adult longevity, female fecundity, or egg viability. Guava, soursop, and acerola were preferred for oviposition, followed by star fruit, Malay apple, cashew, and yellow mombin. Oviposition did not occur on umbu. In general, fruits with better larval development were also more accepted for oviposition.

    This paper documents ethnoveterinary medicines used to treat dogs in Trinidad and Tobago. In 1995, a 4-stage process was used to conduct the research and document the ethnoveterinary practices. Twenty-eight ethnoveterinary respondents were identified using the school-essay method, which is a modified rapid rural appraisal (RRA) technique. Semi-structured interviews were held with these respondents as well as with 30 veterinarians, 27 extension officers and 19 animal-health assistants and/or agricultural officers, and the seven key respondents that they identified. The final step involved hosting four participatory workshops with 55 of the respondents interviewed to discuss the ethnoveterinary data generated from the interviews and to determine dosages for some of the plants mentioned. Supplementary interviews were conducted in 1997 and 1998. Seeds of Carica papaya, and leaves of Cassia alata, Azadirachta indica, Gossypium spp., Cajanus cajan and Chenopodium ambrosiodes are used as anthelmintics. The anthelmintics Gossypium spp. and Chenopodium ambrosiodes are the most frequently used species. Crescentia cujete pulp, Musa spp. stem exudate, the inside of the pods of Bixa orellana, leaves of Cordia curassavica and Eclipta alba plant tops are used for skin diseases. Musa spp. stem exudate, seeds of Manilkara zapota, Pouteria sapota and Mammea americana and leaves of Cordia curassavica, Scoparia dulcis and Nicotiana tabacum are used to control ectoparasites. Dogs are groomed with the leaves of Cordia curassavica, Bambusa vulgaris and Scoparia dulcis. Psidium guajava buds and leaves and the bark of Anacardium occidentale are used for diarrhoea. Owners attempt to achieve milk let-down with a decoction of the leaves of Stachytarpheta jamaicensis. The plant uses parallel those practised in human folk medicine in other Caribbean countries and in other tropical countries. PMID:10821961

    Full Text Available Fruit flies (Diptera, Tephritidae and their parasitoids on cultivated and wild hosts in the Cerrado-Pantanal ecotone in Mato Grosso do Sul, Brazil. Information on frugivorous flies in cultivated or wild host plants and their parasitoids in the Cerrado-Pantanal ecotone in Aquidauana, Mato Grosso do Sul is presented and discussed. Fruit fly samples were collected weekly in specific fruit trees, and McPhail® traps were installed in the same trees for a period of two years. The fruit flies infested ripe and unripe fruits of Averrhoa carambola L., Schoepfia sp., Psidium guajava L. and Pouteria torta (Mart. Radlk and mature fruits of Anacardium occidentale L. and Inga laurina (Sw. Willd. Nineteen fruit fly species were obtained with the combination of sampling methods (collecting fruits and trapping, nine of them obtained with both methods, five found only in fruits and five only in traps. This is the first record of Anastrepha striata Schiner in a species of Sapotaceae, as well as for A. castanea Norrbom and A. daciformes Bezzi in Schoepfia sp. (Olacaceae, and for A. distincta Greene in fruits of P. guajava in the state of Mato Grosso do Sul. Fruit collections simultaneously associated with capture of fruit flies by McPhail traps in the same host plants are essential to understand the diversity of fruit flies and their relationship with hosts and parasitoids. Species of Braconidae and Pteromalidae were recovered, where Doryctobracon areolatus (Szépligeti was the most abundant parasitoid in larvae of tephritids infesting both cultivated and wild host fruits.

    The aim of this work is to identified an environmental deposit able to have stored the atmospheric signal over large time-scale leaning our investigations on lead stable isotopes ({sup 206}Pb, {sup 207}Pb, {sup 208}Pb) and radionuclide ({sup 210}Pb, {sup 137}Cs, {sup 239}Pu, {sup 240}Pu) analysis. Owing to prior studies on anthropogenic lead sources, emission intensity and sedimentary accumulation, we choose to investigate the marine sediments of the Western Mediterranean. In the Gulf of Lions, the sedimentary accumulation is 110 {+-} 7 {mu}g.cm{sup -2} high in good agreement with the atmospheric inventory estimate we made from salt marshes of Camargue (99 {mu}g.cm{sup -2}). The reconstructed lead accumulation through a modelling step coupling {sup 210}Pb and stable isotopes corroborates the regional anthropogenic emissions (Ferrand, 1996). Briefly, in this context of the marine sediments are a relevant proxy to study past lead atmospheric concentration over the last hundred years. In the Alboran Sea, the study area is less constrained and more complex in terms of climatic, meteorological and hydrological conditions. The sedimentary inventory is of 153 {+-} 47 {mu}g.cm{sup -2}, 1,5 higher than in the margin sediments of the Gulf of Lions. The analysis of aerosols, sediments and settling particles evidences a continuity between the atmospheric signal and the sedimentary record. In spite of this encouraging results, the knowledge of the Alboran system is still too restricted in order to unambiguously conclude on accuracy of deep marine sediments of this area to study past atmospheric fallouts.

    Full Text Available The System of Children and Youth Choirs and Orchestras founded forty years ago by Josè Antonio Abreu in Venezuela, has become a significant alternative to the social ills faced by children and young people of the most disadvantaged neighborhoods of the South American metropolis, not only drugs and crime, but also the nihilistic logic that lacks all hope. It makes sense to transfer this experience in the wealthy West where the discomfort takes different forms? The answer is positive: music made together is ideal for sharing basic social values, construction of meaning and important experiences. The group is a perfect example of positive interdependence, commitment and responsibility, emblem of the community, micro-ideal society. Tolerance, inclusion, shared goals: values that can be a solution as well for our ills (bullying, eating disorders, depression, immaturity, inability to decision and commitment, dependence on families etc.. The System of Abreu is the credible alternative to the traditional way of teaching music, cold and elitist, and it stresses the importance of teachers in their role of great responsibility, both pedagogical and psychological.

    Full Text Available The Andean foreland of western Argentina (28°S-33°S corresponds to retroarc deformations associated with the ongoing flat subduction of the Nazca plate beneath the South American lithosphere. This region is characterized by high levels of seismic activity and crustal active faulting. To improve earthquake source identification and characterization in the San Juan region, data from seismology, structural geology and quantitative geomorphology were integrated and combined to provide a seismotectonic model. In this seismotectonic model, the Andean back-arc of western Argentina can be regarded as an obliquely converging foreland where Plio-Quaternary deformations are partitioned between strike-slip and thrust motions that are localized on the E-verging, thin-skinned Argentine Precordillera, and the W-verging thick-skinned Sierras Pampeanas, respectively. In this seismotectonic model, the Sierra Pie de Palo appears to be a key structure playing a major role in the partitioning of the Plio-Quaternary deformations.El antepais andino del centro-oeste de Argentina (28°S-33°S está caracterizado por deformaciones asociadas a la subducción horizontal activa de la placa de Nazca debajo de la litósfera de la placa Sudamericana. En esta región se concentra una importante actividad sísmica y fallamiento cortical activo. Para mejorar la identificación y caracterización de las fuentes sismogénicas en la región de San Juan, fueron integrados y combinados datos de sismología, geología estructural y geomorfología cuantitativa para establecer un modelo sismotectónico. El mismo considera al retroarco del oeste argentino como un antearco con convergencia oblicua donde las deformaciones plio-cuaternarias son particionadas en movimientos compresivos y de transcurrencia dextral. Dichos movimientos están localizados respectivamente en la Precordillera, una faja de pliegues y escurrimientos de cobertura con vergencia hacia el este, y en las Sierras Pampeanas, una faja de fallas inversas de basamento con vergencia hacia el oeste. Según este modelo sismotectónico, la sierra de Pie de Palo corresponde a una estructura mayor que acomoda la partición de las deformaciones plio-cuaternarias.

    Full Text Available El objeto de estudio se ubica en los límites entre Venezuela y Colombia, los cuales han permanecido durante mucho tiempo confusos y ciertas zonas en el golfo de Venezuela fueron siempre el objeto de discusiones. Estos dos países comparten una zona fronteriza de 250 kilómetros, la cual es una frontera de colonización y política entremezcladas donde los fenómenos tienen significación geopolítica, la cual se revela con bastante claridad a través de las tensiones existentes entre los dos estados. Hasta el momento los propósitos realizados para eliminar las posibilidades de conflicto no han encontrado eco, o bien han contribuido a aumentar el debate. Se ponen de relieve los mecanismos de ese conflicto fronterizo y sus repercusiones sobre la población y la puesta en valor con respecto a las regiones estudiadas.

    Full Text Available En el presente trabajo se ha evaluado la subsidencia total de la cuenca de Las Salinas mediante diagramas tiempo - profundidad, considerando la subsidencia inicial, por carga y termotectónica. También se calculó la velocidad de subsidencia interválica en función del tiempo geológico. El área en estudio se ubica aproximadamente entre los paralelos 31°17´S y 32°40´S y los meridianos 66°38´W y 67°48´W en las cercanías de la localidad de Marayes, en el sitio denominado cuenca de Las Salinas. Los diagramas tiempo - profundidad permitieron relacionar cambios en la velocidad de subsidencia de la cuenca durante el proceso distensivo del Mesozoico y el actualmente compresional a la cual esta sometida, obteniéndose valores concordantes con áreas circundantes. Como resultado del análisis se encontró que la velocidad de subsidencia inicial fue de 0,0017 mm/año en el Carbonífero, la que fue aumentando lentamente hasta alcanzar los 0,00875 mm/año en el Cretácico. Este incremento disminuye sensiblemente durante el Cretácico superior, para posteriormente incrementarse abruptamente en el Terciario (0,043 mm/año. Este régimen se mantiene durante el Plioceno a Mioceno, alcanzando valores promedios de 0,269 mm/año, culminando con valores de 0,0973 mm/año. De la comparación entre ambos diagramas de subsidencia se observan distintos ritmos de sedimentación entre el sector norte y sur de la cuenca que podría ser la consecuencia de un fallamiento en el basamento. La comparación de estos valores con los obtenidos en la cuenca de Beazley indican que si bien los valores de subsidencia inicial y ritmo de sedimentación fueron similares. El inicio de la subsidencia en la cuenca de Beazley, se produjo con posterioridad (en el Triásico. La componente termotectónica en ambas cuencas es similar a pesar que el gradiente térmico normal de la zona aumenta sensiblemente en dirección sur.In the present work the total subsidence of Las Salinas basin has been evaluated trough time-depth diagrams, were the initial subsidence by load and thermotectonics were analyzed. The subsidence interval velocity was also calculated in function of the geologic time. The area under study is limited by the geographic coordinates of 31°17´ and 32°40´S latitude and 66°38´ and 67°48´W longitude, in the neighborhood of Marayes locality, in Las Salinas basin. The time-depth diagrams discriminate velocity changes of the basin subsidence rate during the extensional tectonics, and the present day dominant compressional process. The calculated results are in agreement with other regional rates. The obtained rates were: An initial subsidence velocity of 0.0017 mm/year during the Carboniferous period. This velocity had a constant and slow increase during Triassic and early Cretaceous times reaching mean values of 0.00875 mm/year in this last stage. The subsidence rate sensibly decreases during the late Cretaceous, and most part of the Tertiary. Subsequently a sudden change is observed during Pliocene - Miocene times reaching average values of 0.269 mm/year, and ending with rates of 0.0973 mm/year. The time-depth diagrams also show different subsidence rates from the northern and the southern parts of the basin, which could be the consequence of active basement faults during sedimentation. The initial subsidence and sedimentation rates were similar when these results are compared with Beazley Basin data, but the beginning of subsidence in Beazley Basin was later (Triassic time. The thermotectonic subsidences in both basins are similar, although the normal geothermal gradient of the area increases sensibly to the south.

    Full Text Available A resposta das plantas à salinidade depende de fatores fisiológicos, bioquímicos e genéticos. Com este trabalho, objetivou-se estudar o impacto do tempo de aclimatação à solução nutritiva sobre a resposta do cajueiro à salinidade. Plantas de Anarcadium occidentale L., CCP06, cultivadas em vermiculita durante 28 dias, foram transferidas para solução nutritiva de Hoagland com 1/10 de sua força iônica, onde permaneceram por 1 e 7 dias. Ao final dos dois tempos, a solução nutritiva foi suplementada com 200 mM de NaCl, condições em que as plantas foram cultivadas por 0, 12, 24, 48 e 72 h. As plantas aclimatadas por 7 dias á solução de Hoagland apresentaram sinais fisiológicos mais compatíveis com a tolerância ao NaCl, como menor acumulação de Na+ e, também, menores danos nas membranas, peroxidação dos lipídeos, degradação de proteínas, acumulação de aminoácidos livres e acumulação de prolina. A amônia livre foi o melhor indicador da intensidade do estresse salino. Os danos de membranas aumentaram com a acumulação de Na+ nas folhas. Os resultados evidenciam que o tempo de aclimatação das raízes à solução nutritiva influencia a expressão de fatores capazes de atenuar os efeitos do estresse salino.The plant response to salinity depends on physiological, biochemical and genetic factors and on their interaction with external environment.

    In the Oulad Abbou syncline, western coastal Meseta, the Silurian deposits exhibit siliciclastic or mixed siliciclastic/carbonate tidal facies that recorded alkaline basalt flows and syn-sedimentary deformations. These facies are staked into peritidal shallowing upward sequences reflecting the evolution from an infratidal to a supratidal environment. These sequences recorded low-amplitude and high-frequency sea-level variations. The built-up of these rhythmic sequences is related to distensive tectonic that allowed the development of isolated platform from extensive siliciclastic influx. This tectonic event is well recorded in the palaeogeographic evolution of the northern Gondwana platform during the Lower Palaeozoic time. To cite this article: A. Attou, N. Hamoumi, C. R.

    The Middle Cambrian calc-alkaline Oued Rhebar volcanic complex (western Meseta, Morocco) compares with rocks originated in orogenic contexts. The La/Nb ratios are relatively high (5.2), suggesting a lithospheric mantle origin. The La/Ta ratios, higher than 26, and the negative Nb anomaly indicate a lithospheric source contaminated by the continental crust. These rocks were generated in the Mesetian Mid-Cambrian rift and would have inherited their orogenic signature from the partial melting of a previously metasomatized mantle. To cite this article: H.

    To follow the alluvial deposits from the Rhone in Mediterranean Sea, since the principle hydroelectric constructions (1960), it was necessary to find an adequate tracer. The plutonium isotopes have satisfied to the different characteristics. The specificity of the Rhone contribution is bound to the existence of the irradiated spent fuels reprocessing plant of Marcoule; the releases of this plant are characterized by the predominance of Plutonium 238. The results of this study show that the percentage of sediments coming from the Rhone in the recent contribution, is low beyond the pro delta: less than 5% of the sediment of the continental shelf concern the Rhone contribution. However, there are two zones for which the contribution is important and could play a role in the particulate transfer towards the high sea. (N.C.). 157 refs., 60 figs., 50 tabs.

    Full Text Available This Ph.D. study tries to answer the question "Do history textbooks have an impact on people's ideas about other cultures?", by comparing the contents of a large sample of influentialhistory textbooks and curricula (covering 1945-1984 with the results of a wide array of public opinion surveys about the Third World and immigrants (covering 1949-1987.The theoretical part reviews ethnocentrism, cultural relativism and racism as dimensions of cultural images, focuses attention on the phenomenon and mechanism of influence, andassesses the place of the textbook in the complex network of factors acting upon youngsters and adults, inside and outside the school.The methodological part discusses the value of the two sources (relevance, validity and reliability of surveys; availability and use of history textbooks; comparability of both. Universesof both sources are constructed and samples drawn from them. These samples are analysed with mutually attuned question batteries.The double empirical analysis leads to two series of conclusions and trends that are compared with each other. Five parallel trends are found in textbooks and surveys (dominantbut decreasing ethnocentrism; decreasing nationalism; absence of racism; poor awareness of other cultures; social-evolutionist thinking. They coincide in time, while, for textbooks tohave influence, trends there should precede these in the public. Four other trends only partially coincide, or diverge.In the case of still two other trends, mutual influence could be plausibly postulated.In globo, no firm evidence was found for the thesis that history textbooks autonomously influence the public. It rather is the general climate of opinion that, with years of delay, acts upon the textbook authors. The role of these authors, the immediate influences upon them (editors, curricula planners, academics, inspectors, teachers, parents and pupils, their biographies and their degree of representativeness vis-à-vis public opinion, are largely discussed.As a conclusion, the study argues that, by presenting cultural diversity more accurately, new history textbooks could become master cards in the construction of open and tolerant intercultural views and mentalities.

    Examination of long-term records of aquatic ecosystems has provided useful information to find out their major driving forces. Understanding the impact of climate change on these ecosystems, the management of their resources and the extrapolation between sites are the main scopes of actual and emerging studies. Such goals can be achieved by inter-site and inter-ecosystem comparisons. This approach was undertaken during our project which has the originality to tackle with marine and freshwater ecosystems. It allowed us to compile and validate several multi-decadal time series of planktonic and other physical driving forces at local and regional scales. Then, the same methodology based on the analysis of the variability of climate indices and biological data across several spatial scales was used. The different ecosystems analyzed here showed clear response to the North Atlantic climate variability. Although the local differences abrupt changes in community composition occurred in all ecosystems in the middle of the years 80. During this period there was also a major shift in climatic conditions during winter and early spring, suggesting an impact of climatic factors. Phenological changes were also observed in plankton communities in all sites. The consequences of the modifications of plankton dynamics on higher trophic levels were also showed. Fluctuations in plankton have resulted in long-term changes in cod recruitment in the North Sea (bottom-up control). On the other hand, both climate change and the improvement of trophic status in Geneva Lake favored the outbreak of whitefish during the years 90. Lower larval mortality and better recruitment are supposed to be linked to faster growth associated with warmer temperatures and better food conditions induced by better temporal overlap between larvae hatching and zooplankton development.

  3. Plutonium distribution and remobilization in sediments of the Rhone River mouth (North-Western Mediterranean); Distribution et remobilisation du plutonium dans les sediments du prodelta du Rhone (Mediterranee nord-occidentale)

    The aim of the present study was to describe the distribution and remobilization of plutonium (Pu) in the sediments off the Rhone river mouth. Most of the {sup 238}Pu and {sup 239,240}Pu isotopes introduced into the Rhone River were discharged by the liquid effluents released from the Marcoule reprocessing plant, located 120 km upstream the river mouth. Due to its high affinity for particles and its long half life, {sup 238}Pu is a promising tracer to follow the dispersion of particulate matter from the Rhone River to the Mediterranean Sea. During the 3 REMORA cruises, sediment samples were specifically collected in the Rhone pro-delta area and more offshore on the whole continental shelf of the Gulf of Lions. The measurements of alpha emitters gave a first detailed spatial distribution of Pu isotope concentrations in surface sediments off the Rhone mouth. Using {sup 137}Cs concentrations and their correlations with Pu isotopes, we were able to give a first estimate of Pu inventories for the sediments of the study area. In 2001, plutonium inventories were estimated to 92 {+-} 7 GBq of {sup 238}Pu and 522 {+-} 44 GBq of {sup 239,240}Pu for an area of 500 km{sup 2} in front of the Rhone River mouth. Roughly, 50 % of these inventories are trapped in an area of 100 km{sup 2} corresponding to the extent of the Rhone pro-delta zone. In spring 2002, an ADCP, with current velocity and wave measurements, was moored off the Rhone River mouth. This unique in situ dataset highlights the major role of South-East swells in the erosion of pro-deltaic sediments and their dispersion to the South-Westward direction. Plutonium remobilization was examined using a new experimental design based on sediment resuspension processes studied within a linear recirculating flume. For Gulf of Lions sediments and for a given hydrodynamic stress, remobilization fluxes raised a maximum of 0.08 Bq.m{sup -2}.h{sup -1} for {sup 238}Pu and 0.64 Bq.m{sup -2}.h{sup -1} for {sup 239,240}Pu. A first plutonium budget determined for the study area indicates that at least 85 % of the Pu discharged over the 40 past years by the Marcoule reprocessing plant, are currently trapped in the sediments off the Rhone River mouth. Plutonium remobilization is potentially an important process but dispersion of contaminated sediments appeared to be limited in space. These results suggest a low exportation of particulate matter introduced by the Rhone River towards the continental shelf of the Gulf of Lions and the North-Western Mediterranean basin. (author)

    Coesite and graphite were discovered as inclusions in zircon separates from pelitic gneiss associated with a large eclogite body in the North Qaidam UHP terrane. This finding suggests UHP metamorphism at pressures below the diamond stability field. This supports previous indirect UHP evidences, such as polycrystalline quartz inclusions in eclogitic garnet, quartz lamellae in omphacite and P- T estimates for both eclogite and garnet peridotite. The U/Pb and Sm/Nd isotopic ages from the North Qaidam eclogite indicated that continental subduction occurred in Early Palaeozoic, most probably in relation with the collision between the Sino-Korean and Yangtze plates.

    Full Text Available This study evaluated the physicochemical properties and protein and mineral content of honey samples from Ceará State, Northeastern Brazil, one of the major honey exporters in the country. Nutritional importance of the minerals detected was also analyzed. Physicochemical properties were examined according to the AOAC and CAC official methods; the protein content was determined using the Bradford method, and the minerals were analyzed by atomic absorption spectrometry. All analyses were performed in triplicate. The levels of macrominerals sodium (Na, potassium (K, calcium (Ca, and magnesium (Mg varied from 1.80-47.20, 21.30-1513.30, 14.58-304.82, and 2.48-28.33 mg/kg, respectively, and the trace elements iron (Fe, copper (Cu, manganese (Mn, zinc (Zn, selenium (Se, and chromium (Cr varied from 0.12-8.76, 0.07-1.29, 0.06-1.96, 0.07-1.85 mg/kg, 0.36 × 10-3-62.00 × 10-3 and 22.50 × 10-3-170.33 × 10-3 µg/kg, respectively. Myracrodruon urundeuva honey sample had high contents of macrominerals (Na, K, Ca, and Mg. Protein content of the Anacardium occidentale honey sample was the highest (1121.00 µg/g among the samples analyzed. Among the minerals detected in the honey samples, K showed the highest concentration, followed by Ca, Na, and Mg. The presence of trace elements can show environmental contamination. The honey samples studied were free of trace elements contamination, except for Mn; the Piptadenia moniliformis was the only honey sample that was in compliance with the law requirements. The variations of the chemical constituents in the honey samples are probably related to differences in the floral origin and mineral and protein contents and confirm the nutritional importance of Ceará State honey.Este trabalho avaliou propriedades físico-químicas, teores de proteína e minerais em méis do Ceará, um dos principais exportadores do País.

    Full Text Available Soil organic matter accumulation provides benefits to soil productivity and reduces atmospheric carbon concentration. However, little is known about the accumulation of C and N by sandy soils under perennial irrigated crops in semiarid regions. The objective of this study was to evaluate the effect of irrigated fruit orchard cultivation on the stocks of soil organic carbon (SOC and total nitrogen (N of an Arenosol/Quartzpsament from Paraipaba-CE, Semiarid Brazil. Soil samples were taken from irrigated orchards of banana (Musa ssp., cashew (Anacardium ocidentale, guava (Psidium guajava, bullock's heart (Annona reticulata, mango (Mangifera indica, and sapote (Manilkara zapota in the wetted-bulb and non-irrigated area between the plant rows. Additional samples were collected from adjacent areas under secondary Caatinga forest, and under a 2-year-old deforested area. Sampling depths were: 0-0.1, 0.1-0.2, and 0.2-0.4 m. The highest contents of SOC and N were found in the surface layer. The soil bulk density did not change in depth. The stocks of SOC and total N under secondary forest at 0-0.40 m layer were 27.6 and 2.4 Mg ha-1, respectively. Caatinga Forest conversion into fruit orchard cultivation led to a decrease of 5 to 23% and 4 to 21% on SOC and N stocks, respectively. Compared to other soil uses, sapote and bullock's heart contributed for a lower decrease of SOC and N stocks after deforestation. Guava, bullock's heart, mango and sapote contributed for improving the SOC stratification index.O acúmulo de matéria orgânica beneficia a produtividade do solo e reduz a concentração do carbono atmosférico.

    Full Text Available El fenómeno sísmico está estrechamente ligado a cambios de gravedad producto de la deformación y de cambios de densidad en la corteza. Se ha establecido una red de control geodésico con el propósito de establecer relaciones espacio-temporales en la evolución del campo gravitatorio producido por actividad tectónica. La red está compuesta por 65 puntos fijos bien materializados y cubre un área de 3.500 km2 con la ciudad de San Juan en su centro. Diez años de mediciones periódicas han permitido evaluar las velocidades de variación de la intensidad del campo gravitatorio; éstas se ajustan razonablemente por el modelo estadístico de regresión lineal de las observaciones de la gravedad versus tiempo. Los resultados señalan el levantamiento actual de la Precordillera Oriental, que se refleja en aumentos de gravedad (g en las estaciones situadas al oeste del fallamiento Villicum-Ullum-Zonda y en la disminución de g al este de la estructura. identificamos tres segmentos activos: a la falla de La Laja con fuerte disminución de g, b el segmento Maradona-Cerro Bayo, con aumentos de g al oeste de la sierra Chica de Zonda y c una disminución de g en la falla de La Rinconada. Los datos muestran actividad tectónica en el sistema de fallas del Tulum que exhibe un gradiente en la dirección del lineamiento Cerro Valdivia-Cerro Barboza-Sierra de Pie de Palo que se incrementa hacia el este. Sus variaciones máximas negativas se observan al este del cerro Barboza. Mapas de anomalías magnéticas y gravimétricas señalan patrones en el basamento coincidentes con estas estructuras activas.Earthquake is closely tied up with gravity changes on the basis of crustal deformation and crustal density changes. A network of areal geodetic control was set up with the purpose of establishing space-time relations in the evolution of the gravity field produced by tectonic activity. The network is composed by 65 bench marks well materialized in the field, and extends over an area of about 3,500 km2 centered in the San Juan city. Ten years of gravity periodic measurements have allowed to evaluate the speeds of the gravitational intensity field variations. These gravity changes adjust reasonably well with the statistical lineal regression model applied to the gravity versus time observations. The observed data support the current uplift of the Eastern Precordillera, reflected in increases of gravity (g in all bench marks located westwards of the Villicum-Ullum-Zonda fault and in the decrease of gravity eastwards of this structure. We identify three segments of larger activity: a La Laja fault with strong decreases of g, b Maradona-Cerro Bayo segment, with increases of g westwards of the Sierra Chica de Zonda and c decreases of g at La Rinconada fault. The data show tectonic activity in the Tulum faults system, gravity changes have lined up in the Cerro Valdivia-Cerro Barboza-Sierra de Pie de Palo lineament and increase to the east. The largest variations are observed eastwards of the Barboza hill with a minimum of g. Magnetic and gravity anomaly maps indicate basement patterns consistent with these active structures.

    The Los Frailes Meseta (Bolivia) is one of the large tertiary ignimbritic fields of the inner volcanic arc from Central Andes (Central Volcanic Zone. CVZ), in contact zone between the Altiplano to the west and the Eastern Cordillera to the east. Field observations and mineralogical and geochemical studies (major and trace elements) lead to distinguish two types of volcanism in the western border to the Meseta. During the Middle Miocene and Pliocene, the volcanic activity can be subdivided into three pyroclastic emission cycles, the Larco, Coroma and Pliocene ignimbrites, the first two being separated by the Quechua 2 orogeny. All these ignimbrites are very similar and correspond to peraluminous rhyolites to rhyodacites. In the studies area, the Coroma cycle is the only one where an ignimbrite-less evolved resurgent dome association can be observed. Beside these ignimbrites, isolated small lava flows and domes overlay and/or intrude all the other formations. They are meta-aluminous lavas with a shoshonitic affinity. A quaternary age can be attributed to his second volcanism. These two volcanic types are well-known in the CVZ and are related to the different deformation stages, either compressional or extensional, which occur alternately in the Cordillera since 26 Ma.

    The interpretation of old fundamental research works and the results obtained by this study based on: the analysis of apatite fission tracks (AFT), the burial evolution curves and the sequential analysis of outcrop section, as well as the curves of signal of gamma ray (GR) analysis from drilling wells, allow to precise that the geodynamic evolution of the studied Algerian sedimentary basins (Ahnet and Sbaa) have been occurred principally in the Paleozoic era. The analysis of burial evolution curves shows that during the Paleozoic period, the sedimentation is controlled by the tectonic subsidence, particularly at the end of Carboniferous in the favor of Ougarta folding. The curves indicate an uplift from the Permian to middle Jurassic, expressed by an important erosion of sedimentary series and is considered as a response of thermal convection of the Saharan platform followed by thermal subsidence. This can be explained by the halt motion of rift extension caused by the opening of the Atlantic Ocean. To bring the sequential analysis out, it appears that Ahnet and Sbaa basins present contrasted stratigraphic recordings, so much in time than in space, indicated the different effects from subsidence and erosions according to their sectors. In thermal point of view, temperatures are still moderate in Sbaa depression and favorite the preservation of organic matter and might generate hydrocarbons until now. However, these conditions are not similar to ones in the case of Ahnet basin. In the North part of Ahnet basin (MRS-1, MSL-1), the ages are around 50 Ma, attested that sedimentary layers have been sustained a post-Hercynian thermal phase. This phase could be estimated probably more than 100 C. This is also produced during the regional extension of the Triassic-Jurassic rifting. This episode could also be responsible of disappearance (total?) of pre-existence fission tracks in the Devonian layers of the well MSR-1, which exhibits at the depth 505 m under the Hercynian unconformity an age FT of 100 my. In the south part, ages are respectively 37 and 26 Ma at the depths: 1030 m (MKRN-1) and 1532 m (BH-5). These suggest that Cenozoic thermal alteration of tracks is more intense than in the north of the basin and may reflect important erosion, eventually accompanied with high geothermal gradients. In conclusion, three thermal episodes in the studied area have influenced the formation and the migration of hydrocarbons and consequently their nature; Varisc orogenesis, the Atlantic opening to Jurassic and the thermal convection of the Hoggar at the Eocene age. Clearly, the latest is the most event which affects the hydrocarbons of Ahnet reservoirs as shown by the increased temperatures from the north to south of the studied area. A secondary cracking occurred certainly during Eocene transforming oil to gas. Also, the outcrop studies allow defining the deposits influenced by storms (shallow depth {<=} 100-150 m) in the sedimentary series of the Ougarta ridge and the evident deposits of Jokulhlaups in the unit IV in Kheneg Etlaia, locality (Ougarta). This can be observed distally at the Cambrian-ordovician of the well MSR-1 (Ahnet). (author)

    The production of extracellular xylanase by three species of Pleurotus species i.e. P. florida, P. flabellatus and P. sajor caju was studied under in vivo condition during their cultivation on pretreated lignocellulosic wastes. Neem (Azadirachta indica) oil and ashoka (Saraca indica) leaves extract were used for pretreatment of paddy straw and wheat straw. Between these two wastes, paddy straw pretreated with neem oil, supported better xylanase production than wheat straw. Initially, xylanase production was low but it increased in subsequent days and reached at peak on 25th day of cultivation of Pleurotus species. Thereafter, there was decrease in the activity of the enzyme. On 25th day of incubation P. florida produced maximum xylanase on neem oil pretreated paddy straw i.e. 10.59 Uh—1ml—1. Among the three species, P. florida showed maximum enzyme activity followed by P. flabellatus and P. sajor caju. PMID:23273208

    Co-occurring species often have different strategies for tolerating daily cycles of water stress. One underlying parameter that can link together the suite of traits that enables a given strategy is wood density. Here we compare hydraulic traits of two pioneer species from a tropical forest in Panama that differ in wood density: Miconia argentea and Anacardium excelsum. As hypothesized, the higher wood density of Miconia was associated with smaller diameter vessels and fibres, more water stress-resistant leaves and stems, and roughly half the capacitance of the lower wood density Anacardium. However, the scaling of hydraulic parameters such as the increases in leaf area and measures of hydraulic conductivity with stem diameter was remarkably similar between the two species. The collection of traits exhibited by Miconia allowed it to tolerate more water stress than Anacardium, which relied more heavily on its capacitance to buffer daily water potential fluctuations. This work demonstrates the importance of examining a range of hydraulic traits throughout the plant and highlights the spectrum of possible strategies for coping with daily and seasonal water stress cycles.

    Pleurotus sajor-caju, P. sapidus, P. cornucopiae, and P. ostreatus mushrooms were produced on unsupplemented wheat straw. The yield of mushrooms averaged 3.6% (dry-weight basis), with an average 18% straw weight loss. Lignin losses (average, 11%) were lower than cellulose (20%) and hemicellulose (50%) losses. The cellulase digestibility of the residual straw after mushroom harvest was generally lower than that of the original straw. It does not appear feasible to simultaneously produce Pleurotus mushrooms and a highly delignified residue from wheat straw. (Refs. 24).

    1983-01-01

    The species- and metal-specific translocation of cadmium and mercury from the substrate to the fruiting bodies of 6 higher fungi has been investigated. The 6 species differed greatly in their ability to translocate cadmium and mercury. The highest translocation rates displayed Pleurotus flabellatus: 75.0% of the applied cadmium and 38.5% of the mercury could be recovered from the fruiting bodies. High translocation rates also found with Pleurotus ostreatus (19.3 and 38.5% for cadmium and mercury, respectively). This compares with only 1.27% of cadmium and 8.42% of mercury in Agaricus bisporus or 3.71% of cadmium and 3.63% of mercury in Pleurotus sajor caju. For Agaricus bisporus it was shown that there was proportionality of translocation over a 1:10 concentration range. In 4 out of 6 species there was a tendency towards higher heavy metal contents in later crops, when calculated on the basis of ..mu..g/g of dry fruiting body. In 4 out of 6 more mercury than cadmium was translocated into the fruiting bodies, the Cd/Hg ratios being 6.6, 2.0, 5.6, and 3.2, respectively. In Pleurotus sajor caju the ratio was about 1. Only in Pleurotus flabellatus more cadmium than mercury was found in the fruiting bodies (Cd/Hg ratio 0.65).

    The capability of seven basidiomycetes (Trametes versicolor, Poria placenta, Pleurotus florida, P. ostreatus, P. sajor-caju, P. eryngii, Stropharia sp.), one ascomycete (Chaetomium globosum) and five hyphomycetes and moulds (Humicola grisea, Trichoderma viride, Aspergillus terreus, Paecilomyces varioti, Papulaspora immersa) to solubilize medium and high volatile bituminous coals (types A and B) as well as four types of lignite B from Germany was tested in surface cultures. The intensity of bioliquefaction was determined by estimating the rate of droplet formation and by measuring the loss of weight of the coal granules gravimetrically. The bituminous coals with a relative high degree of coalification were only moderately converted by Trametes versicolor, Pleurotus florida, P. ostreatus and P. sajor-caju. The three species of Pleurotus caused the greatest rate of biosolubilization of lignite, yielding a loss of weight of the coal granules of more than 5.8% with a maximum of 7.6% with P. florida. The non-basidiomycetes proved to be less active with a liquefaction rate of up to 3.5% with Trichoderma viride. In general, the geologically younger lignite coals were more effectively solubilized than the older hard coals. The volatile matter and the oxygen content proved to be the principal factors influencing the intensity of bioconversion.

    Full Text Available There is a general trend towards a continuous increase in fresh market sales of mushrooms and many methods have been researched to improve quality and shelf life during storage and marketing. As it is known, mushrooms are a very perishable commodity, with very high respiration rate and rapid quality deterioration, when kept at ambient temperature. In order to study the effect of modified atmosphere packaging (MAP on the quality of three species of oyster mushrooms, P. ostreatus, P. sajor-caju and P. eryngii, whole mushrooms were packaged with two polymeric low density polyethylene films – Vileda Freshmate (A and PE 52 LV Amcor (B, with passive modified atmosphere and stored at 4ºC. The quality and stability of MA packaged mushrooms were assessed, during storage, by package atmosphere composition (O2, CO2, soluble solid contents, weight loss, texture, surface colour and exudates measurements. It was verified that on the seventh day the P. ostreatus and P. sajor-caju carpophores presented identical quality, when packaged with the two films types, thereafter some decay was observed. Carpophores of P. eryngii had the same quality in the two film types at the end of the established storage.

  16. Phytochemicals with radioprotection and radio-sensitizing potential

    International Nuclear Information System (INIS)

    Ionizing radiation induces DNA damage and are harmful to mankind. They act through free radical generation, which target the double bonds of all cellular macromolecules. The radiation damage may be classified as probabilistic or deterministic, depending on the dose of radiation exposure. Since radiation affects multiple organs so those drugs which protect many organs, would be more beneficial. In this process herbal extracts, which are cocktail of several phyto-chemicals, would be more promising. Initially sulphur containing bio-molecules were identified as radio-protector, but now many secondary metabolites from plant kingdom, have been reported to be radio-protective. They have different mechanism of action, but most of them either prevent the FR induced DNA damage or accelerate the DNA repair process. Aminofostine, WR-2721, 159243, 2926 are some of the examples. However they have limited use because of associated cytotoxicity. Eicosanoids, topoisornerase inhibitors (e.g. camptothecin, topotecan), and the hypoxia-activated anthraquinone AQ4N have shown radioprotecting potential. Several plant products, derived from Tulsi, Vinca alkaloids, taxans, turmeric, Rubia cordifolia, Semecarpus anacardium and several plants rich in polyphenols and flavones have shown hemotherapeutic potential. Similarly, Hippophae, rhodiola imbricata, Podophyllum hexandrum, Ocimum sancturn, Plumbago zeylanica etc have shown radioprotection. Rubia cordifolia has shown both chemotherapeutic and radioprotective property in rats and A-431 cells. Similarly Semecarpus anacardium extract has shown cell cycle arrest in DU-145 cells. (author)

O experimento foi desenvolvido em delineamento inteiramente casualizado, sendo cinco tratamentos (marcas denominadas A, B, C, D e E e três repetições, para as polpas de abacaxi, acerola, caju, goiaba e maracujá. Foram analisados os parâmetros pH, acidez titulável expressa em ácido cítrico, sólidos solúveis, ratio, vitamina C, açúcar redutor e quantificação da perda de vitamina C após 90 dias de armazenamento sob congelamento, em polpas de acerola e caju. Os dados obtidos foram submetidos à análise de variância, e as médias, comparadas pelo teste de Tukey, ao nível de 5% de probabilidade. A marca D apresentou não conformidade com a legislação para todas as polpas em, pelo menos, um dos parâmetros avaliados. Foi observado maior número de amostras em inadequação para o teor de vitamina C e, de forma geral, as polpas avaliadas apresentaram valores abaixo das especificações exigidas pelos Padrões de Identidade e Qualidade (PIQ para as mesmas. Todas as amostras avaliadas tiveram redução do teor de vitamina C durante armazenamento sob congelamento, sendo que nenhuma marca de polpa de acerola e apenas uma de caju apresentou, ao final de 90 dias, teor de vitamina C de acordo com o estabelecido pelo PIQ. Conclui-se que é necessária uma intensificação na fiscalização no processamento de polpas de frutas congeladas para garantia da saúde do consumidor.

    Full Text Available Aren (Arenga pinnata Merr. is a multipurpose tree that can be utilized for palm sugar, alcoholic drinks, beverages and construction wood. The use of aren sawdust has not been studied intensively. This study examines the utilization of aren sawdust as cultivation media for edible mushrooms. Aren sawdust was mixed with rice bran, CaCO3, gypsum, fertilizers and distilled water before sterilization in 30 minutes pressurized autoclave at 1210C and 1.5atm. The mixed media was inoculated with pure cultures containing four mushrooms species (Pleurotus flabellatus, P. ostreatus, P. sajor-caju and Lentinula edodes and incubated for five weeks to allow mycelium growth producing fruit bodies. The fruit bodies were harvested everyday within four months and examined for its gained mushroom-weight and biological conversion efficiency/BE. The core part of aren trunk was cut into smaller pieces of 10 cm (width by 5 cm (thickness, by 120 cm (length. Each core sample was bored from the surface inward, creating holes with a particular distance apart. Each hole was inoculated with pure cultures containing 6 mushroom species (four species above, P. cystidiosus and Auricularia polytricha. The inoculated samples were slanted on bamboo support, and placed in a bamboo hut. Harvesting was carried out everyday after the fruiting body became mature and examined for its gained mushroom weight. Results show that the use of sawdust supplemented with nutritious material is more likely to improve the mushroom yield than that of aren sawn-timber core. In this case, the BE values with aren-sawdust media were 21.97-89.45% (P. flabellatus, 15.36-105.36% (P. ostreatus, 63.88-76.86% (P. sajor-caju, and up to 62.88% (L. edodes. Meanwhile, the yields (gained mushroom weight with aren sawn-timber media were 210g (P. ostreatus, 368g (P. flabellatus, 331g (P. sajor-caju and 48g (A. polytricha; however, P. cystidiosus and L. edodes inoculated on aren stem core failed to grow.

    Transgenic potatoes expressing glyceraldehyde-3-phosphate dehydrogenase (GPD), isolated from the oyster mushroom, Pleurotus sajor-caju, had increased tolerance to salt stress (Jeong et al. Biochem Biophys Res Commun 278:192-196, 2000). To examine the physiological mechanisms enhancing salt tolerance in GPD-transgenic rice plants, the salt tolerance of five GPD transgenic rice lines (T1-T5) derived from Dongjin rice cultivar were evaluated in a fixed 150 mM saline environment in comparison to two known wild-type rice cultivars, Dongjin (salt sensitive) and Pokali (salt tolerant). Transgenic lines, T2, T3, and T5, had a substantial increase in biomass and relative water content compared to Dongjin. Stomatal conductance and osmotic potential were higher in the GPD transgenic lines and were similar to those in Pokali. The results are discussed based on the comparative physiological response of GPD transgenic lines with those of the salt-sensitive and salt-tolerant rice cultivars.

    This regional study is comprised of three case studies, which concentrate on Greater Buenos Aires, Caracas and Rio de Janeiro - Caju. Each case focuses on the analysis of specific aspects of urban poverty, energy availability and policies to improve living conditions from the energy point of view. Unlike other developing regions in the world, the problem of energy poverty in Latin America has been concentrated increasingly in the large cities and urban areas. This problem has deep systemic, economic, political, structural and cultural roots. Providing basic energy services to the urban poor is an issue that requires far more attention and expertise than it is receiving today, and therefore WEC has taken the initiative to address this issue, and the results of their study are presented in this report.

    Olive mill wastewater (OMW) still is a major environmental problem due to its high chemical oxygen demand (COD) and total phenolic content (TPC), contributing for the high toxicity and recalcitrant nature. Several attempts have been made for developing more efficient treatment processes, but no chemical or biological approaches were found to be totally effective, especially in terms of toxicity reduction. In this context, the main purpose of this study was to investigate the treatability of OMW by the combination of photocatalytic oxidation, using two nanomaterials as catalysts (TiO2 and Fe2O3), with biological degradation by fungi (Pleurotus sajor caju and Phanerochaete chrysosporium). Photocatalytic oxidation was carried out using different systems, nano-TiO2/UV, nano-Fe2O3/UV, nano-TiO2/H2O2/UV and nano-Fe2O3/H2O2/UV. The effectiveness of the treatment was assessed through color (465nm), aromatics (270nm), COD and TPC reductions, as well as by the decrease in toxicity using the bacterium Vibrio fischeri. The chemical treatment with the system nano-TiO2/H2O2/UV promoted 43%, 14%, 38% and 31% reductions in color, aromatics content, COD and TPC, respectively. However no toxicity reduction was observed. The combination with a biological treatment increased the reduction of COD and TPC as well as a reduction in toxicity. The treatment with P. chrysosporium promoted the highest reduction in toxicity, but P. sajor caju was responsible for the best reduction in COD and TPC. However, the biological treatment was more effective when no hydrogen peroxide was used in the pre-treatment.

  12. Upgrading of oil palm wastes to animal feeds

    International Nuclear Information System (INIS)

    A huge amount of agricultural wastes are discarded or burned causing the serious environmental pollution problems in the world. Upgrading of these wastes into useful end-products is suggested not only to recycle the agro-resources but also to reduce pollution. Empty fruit bunch (EFB), stalk material after fruit stripping, is a major cellulosic waste of the palm oil industry. The current availability of EFB in Malaysia is estimated to be 3 million tones per year. EFB is normally incinerated to produce bunch ash. Burning and incineration processes emit considerable amount of smokes and pollutants thus affecting surrounding areas. Recently, it has been realized that there is a need to utilize these by-products effectively in order to improve the economic situation of the oil palm industry as well as to reduce pollution problems. EFB is a valuable and useful biomass. This paper describes the production of animal feed and mushroom from oil palm wastes by radiation and fermentation treatment. The process is as follows: decontamination of microorganisms in fermentation media of EFB by irradiation, inoculation of useful fungi, and subsequently production of proteins and edible mushrooms. The dose of 30 kGy was required for the sterilization of contaminating bacteria whereas the dose of 10 kGy was enough to eliminate the fungi. Among many kinds of fungi tested, Coprinus cinereus and Pleurotus sajor-caju were selected as the most suitable microorganism for the fermentation of EFB. The protein content of the product increased and the crude fiber content decreased after solid state fermentation. P.sajor-caju was suitable for the mushroom production on EFB with rich bran and the residue can be used as the ruminant animal feeds. It is expected that the process is applicable to other cellulosic wastes such as sugar cane bagasse, rice straw, etc. produced in other Asian countries, and contribute to reduce the environmental pollution problems.

    OpenAIRE

    Pousá Castelo, Manuel

    2013-01-01

    En los manuales españoles de 1º de Bachillerato, los pueblos indígenas quedan relegados a lugares marginales en la enseñanza de la Historia, no se presentan o se ocultan los procesos de usurpación territorial y agresión sufridos a manos principalmente de los occidentales. Tanto los libros como los alumnos aceptan además la arcaica doctrina de la terra nullius, despreocupándose por los derechos de propiedad de las sociedades más débiles. El alumnado no se interesa en general por los pueblos in...

    INTRODUCCIÓN La Obesidad es ya uno de los mayores problemas de salud pública en los países occidentales y se prevé que en un futuro cercano sea una verdadera epidemia. La naturaleza de este problema no es estética, como es habitual que se valore en nuestro entorno social. Tiene un sinfín de repercusiones. Empezando por las comorbilidades metabólicas que la acompañan, las complicaciones osteoarticulares que desencadena o simplemente el rechazo social que muchas veces genera. Todo ello sumad...

    Es mucho lo que se conoce sobre la influencia de Oriente en al-Andalus pero, en cambio, es mucho menos lo que sabemos sobre la forma en que el territorio occidental era percibido por los orientales. Como afirma N. Clarke en este inteligente, sólido y, por momentos, brillante estudio sobre las narrativas árabes en torno a la conquista, las relaciones entre ambas áreas eran complejas. A la rivalidad política se le añadía la percepción de un déficit cultural del que los occidentales eran siempre...

    El abuso de sustancias en los países occidentales ha acontecido un problema de salud pública. Lamentablemente, estas sustancias de abuso son además una carga para las personas que no las consumen, por ello, la población pediátrica es especialmente vulnerable. Desde la década de los ochenta, la eventual presencia y disposición de una sustancia de abuso en el organismo y su correlación con efectos clínicos y/o subjetivos ha sido evaluada mediante el análisis de plasma u orina. Sin embargo, real...
