Abstract To describe total bilirubin production in healthy term infants, we measured the end-tidal breath CO, corrected for ambient CO (ETCOc), with an automated sampler and electrochemical (EC) CO instrument. For infants of mothers with a negative Coombs' test, the ETCOc was 1.3 +/- 0.7 microL/L (n = 397) and the serum bilirubin on day 3 postpartum was 73 +/- 35 mg/L (n = 381). In contrast, the ETCOc for infants with ABO or Rh incompatibility, a positive direct Coombs' test, and bilirubin > 130 mg/L (n = 9) was significantly higher, 1.8 +/- 0.8 microL/L, than for those who had a positive Coombs' test result but whose bilirubin was < or = 130 mg/L (n = 12), 1.0 +/- 0.5 microL/L (P < 0.05). At 2 to 8 h postpartum seven term babies from mothers with insulin-dependent diabetes had ETCOc of 1.8 +/- 0.7 microL/L, significantly higher than that in the other term infants [1.3 +/- 0.7 microL/L (n = 390), P < 0.04]. Their bilirubin concentration at 72 +/- 12 h was also higher: 121 +/- 45 mg/L (n = 7) vs 73 +/- 34 mg/L (n = 374; P = 0.03). We conclude that ETCOc measurements may be helpful in understanding the mechanisms of jaundice in healthy term infants in a variety of conditions.

ABSTRACT Cultured porcine thyroid cells, maintained in the differentiated state by dibutyryl cyclic AMP, responded to serotonin (5-HT; 10 nmol/l to 1 μmol/l) with a depolarization of the membrane potential, but did not respond to histamine (100 μmol/l) or dopamine (1 μmol/l). The resting membrane potential of these cells was about − 71 mV, maximal concentrations of 5-HT (1 μmol/l) inducing a depolarization to approximately −53 mV. Methysergide or phenoxybenzamine, but not propranolol, abolished the response to 5-HT. Sensitivity to 5-HT was reduced by previous exposure of cultures to TSH, the β-adrenoceptor agonist salbutamol or 5-HT itself. J. Endocr. (1985) 107, 397–401

Leptospirosis is a zoonotic bacterial disease that affects vulnerable populations such as rural subsistence farmers and urban slum dwellers. Leptospirosis is an infectious disease caused by pathogenic organisms belonging to the genus leptospira, that are transmitted directly or indirectly from animals to humans. In Mongolian human cases of leptospirosis has not been reported yet and this zoonotic disease not well study. We had use the kit in order to detect Pomona, Tarassovi, Hebdomadis, Icterohaemorrhagiae, Grippotyphosa, Sejroe and Canicola serotype by Enzyme-linked immunosorbent assay (ELISA) test. We analyzed 397 samples of bovine serum by indirect ELISA. The bovine serum samples were collected from Selenge province, and out of 101 samples 2 were positive. And, out of 171 bovine 1 serum was positive in Tov province. In contrast, no positive samples detected in 137 swine serum. Linnodee leptospira /ireland/- ELISA kit can detect a swine Bratislava serotype and cattle Hardjo serotype. To detect Hardjo serotype, 397 samples of cattle serum and 137 samples of swine serum were investigated. The 29 serum of cattle were positive, which has 7.3% infection rate, and, only one swine sera was positive out of 137, that has 0.73% infection rate. The 137 swine serum were tested by ELISA, which can detect Leptospira Bratislava serotype; and 12 out of that were positive. This indicates 8.7% of all sample are positive. Total of 397 bovine sera were examined by ELISA and specific antibody against Pomona, Tarassovi, Hebdomadis, Icterohaemorrhagiae, Grippotyphosa, Sejroe and Canicola serotype detected in 0,75 % (3 sera samples). Hardjo serotype detected in 7.3 % (29 sera) of bovine samples and 7.6 % (1 serum) of 13 swine sera samples and furthermore, bratislava serotype antibody detected in 8.7% (12 sera) of the pigs included in our study. Our study indicates that risk of human leptospirosis infection through animal derived food consumption, soil and water contamination is present due to prevalence of hardjo and bratislava serotype in cattle and pig farms. These results correlates with study conducted by Odontsetseg N. PhD in 2005 which stated that Hardjo serotype of Leptospira interrogans was detected in cattle herd in our country and these suggest that leptospirosis is prevalent in certain regions of our country.

Texto completo da fonteResumo:
ABSTRACT The actions of forskolin have been investigated to determine to what extent its effects on steroidogenesis in rat adrenal preparations are dependent on activation of adenylate cyclase. In zona glomerulosa preparations, stimulation of both aldosterone and corticosterone production was obtained at concentrations of forskolin between 1 and 10 μmol/l. The effects of 10 μmol forskolin/l were additive with those of low doses (1 pmol/l) of corticotrophin (ACTH), but not with those of high doses (1 nmol/l) of ACTH. In contrast, in zona fasciculata/reticularis cells, doses of forskolin up to 10 μmol/l produced no significant stimulation of corticosterone production either alone or in the presence of ACTH (1 pmol/l and 1 nmol/l). The response to 1 nmol ACTH/l was attenuated in the presence of forskolin (10 μmol/l) in both zona glomerulosa and zona fasciculata/reticularis cell preparations. Cyclic AMP production increased progressively with dose up to 100 μmol forskolin/l in zona glomerulosa cells, whereas corticosterone production was maximal between 10 and 30 μmol forskolin/l and decreased at 100 μmol forskolin/l. In zona fasciculata/reticularis cells, cyclic AMP production was also increased by forskolin (1 and 10 μmol/l). The stimulation of zona glomerulosa steroido-genesis by forskolin (1–10 μmol/l) and ACTH (1–100 pmol/l) were both reduced by the adenylate cyclase inhibitor, N6-phenylisopropyladenosine (100 μmol/l). The calcium channel inhibitor, nifedipine, only reduced the steroidogenic response to forskolin (3 μmol/l) at doses of 300 μmol/l whereas the response to 8·4 mmol K+/l was inhibited at 10 μmol nifedipine/1. Although there is some dissociation between the effects of forskolin on cyclic AMP and steroidogenesis, the results are generally consistent with the view that the effects of forskolin in rat zona glomerulosa cells are mainly dependent on activation of adenylate cyclase. This contrasts with the effects of forskolin in bovine fasciculata cells which are reported to be mediated by activation of voltage-regulated calcium channels.

Texto completo da fonteResumo:
Serum bicarbonate deficiency is a disorder frequently found in human patients with acute (AKI) and chronic (CKD) kidney disease, due to abnormalities in kidney generation and reabsorption of bicarbonate. Although alkali supplementation is usually performed in both humans and veterinary CKD patients, data regarding the frequency of bicarbonate disorders in AKI and CKD dogs are scarce. The aim of the present study is to assess the frequency and the severity of bicarbonate deficiency of dogs affected by AKI, acute chronic kidney disease (ACKD), and CKD, and to investigate its possible association with the IRIS grade/stage as well as with disorders of calcium phosphate metabolism. A retrospective evaluation of the serum biochemical panels of all dogs with diagnoses of AKI, ACKD, and CKD referred to the nephrology and urology service of the Veterinary Teaching Hospital of the University of Pisa, between January 2014 and January 2022, was performed. Bicarbonate deficiency was defined as serum bicarbonate < 22 mmol/L and classified as moderate (between 18 and 22 mmol/L) or severe (<18 mmol/L). Serum bicarbonate deficiency was found in 397/521 dogs (76%), of which 142/397 (36%) showed moderate deficiency, and 255/397 (64%) severe deficiency. Dogs with AKI and ACKD showed a significantly higher frequency of bicarbonate deficiency (p = 0.004) and severe forms compared to CKD dogs (p = 0.02). In AKI and ACKD dogs, a negative linear correlation was found between serum bicarbonate and serum creatinine, urea, and phosphate. The frequency of bicarbonate deficiency was higher in the later stages of the disease in both AKI (p = 0.01), ACKD (p = 0.0003), and CKD dogs (p = 0.009). Dogs with serum CaxP ≥ 70 mg2/dL2 showed a higher frequency of bicarbonate deficiency (p = 0.01) and showed severe forms (p = 0.01) compared to dogs with CaxP < 70 mg2/dL2. Serum bicarbonate deficiency seems to be a very frequent disorder in both AKI, ACKD, and CKD dogs, with an increasing frequency and severity in more advanced stages of kidney disease. The higher frequency and severity of bicarbonate deficiency in AKI and ACKD may be caused by a more severe and sudden loss of kidney function, or extra-renal factors. Finally, the association between frequency and severity of bicarbonate deficiency and abnormal CaxP may suggest a potential connection between metabolic acidosis and bone mineral disorders.

Texto completo da fonteResumo:
AbstractA pollen cDNA library of Japanese pear (Pyrus pyrifolia) from the family Rosaceae was constructed and a cDNA (bgn-1) of 1408 bp, which encodes a protein (BGN-1) secreted from growing pollen tubes, was cloned and sequenced. bgn-1 cDNA is composed of a 5′-untranslated region of 47 bp, an open reading frame of 1194 bp encoding 397 amino acid residues and a complete 3′-untranslated region of 167 bp. Alignment of the deduced amino acid sequence of bgn-1 with that of barley (Hordeum vulgare) β-1,3-glucanase (GII) showed 39.7% amino acid identity. Several residues that were critical for the function of GII were conserved in the deduced BGN-1 polypeptide. Moreover, hydrophobic cluster analysis (HCA) showed an overall HCA homology score of 87.1% and analysis of BGN-1 with the 3D-PSSM program predicted a three-dimensional structure of BGN-1 highly homologous to that of barley GII with ≥95% certainty. These results suggest that the cloned bgn-1 cDNA encodes a β-1,3-glucanase-like protein in Japanese pear. The predicted mature protein (375 amino acids) has a theoretical molecular mass of 40 723 Da, a basic pI of 9.59 and a diagnostic amino acid residue mode of D, L, S and L, which is very similar to that of growth-related subfamily D (D, L, S and Q) in cereals. A ProXXPro repeat is also found between positions 352 and 367 in the C-extension region.

As mudanças no perfil do consumidor, interessado em uma alimentação mais saudável, associada a praticidade e conveniência, têm conduzido a um novo ramo da tecnologia de alimentos, o processamento mínimo. Em citros, esse processo contribuirá para o aumento do consumo da fruta in natura, possibilitando agregação de valor ao produto e inserindo uma nova opção ao consumidor. O presente trabalho teve como objetivo avaliar o efeito de solução de cloreto de cálcio e película de alginato de sódio na fisiologia e na conservação de laranja 'Pêra' minimamente processada. A qualidade da laranja minimamente processada submetida aos tratamentos com cloreto de cálcio a 1%, alginato de sódio a 1% e o controle (sem aplicação de tratamento) foi monitorada por análises fisiológicas, físico-químicas, microbiológicas e sensoriais por um período de 12 dias de armazenamento a 5°C, sendo realizadas a cada três dias. A atividade respiratória da laranja 'Pêra' foi influenciada pelos tratamentos; com destaque para o tratamento com alginato de sódio (1%) que se mostrou eficiente na minimização da atividade respiratória, apresentando também menores contagens de bactérias psicrotróficas e menor perda de massa ao longo do período de armazenamento. Porém, as amostras submetidas a este tratamento, tiveram sua qualidade prejudicada em relação aos teores de ácido ascórbico, açúcares, teor de sólidos solúveis e firmeza. No final do armazenamento, o tratamento com cloreto de cálcio (1%) apresentou a melhor eficiência na manutenção das características iniciais do fruto, preservando os teores de ácido ascórbico, acidez titulável, 'ratio', açúcares e firmeza, evidenciada pela menor solubilização de pectinas. A análise microbiológica detectou valores insignificantes para bactérias psicrotróficas, bolores e leveduras e coliformes totais em todos os tratamentos, mostrando que os cuidados tomados com as condições higiênicas levaram à obtenção de um produto com padrão microbiológico de acordo com a legislação de alimentos, apresentando ausência de Salmonella e coliformes a 45°C. Sensorialmente, a laranja minimamente processada tratada com cloreto de cálcio (1%) e o controle, apresentaram-se em condições de consumo por nove dias de armazenamento. Comparando-se os diversos parâmetros apontados pelos provadores, pôde ser observado que o alginato de sódio (1%) destacou-se como sendo o melhor tratamento para a manutenção da qualidade sensorial de laranja 'Pêra' minimamente processada.Changes in the profile of the consumer interested in healthier nutrition, associated with the practicality and convenience, have led to a new branch of food technology: minimal processing. In citrus, this processing will contribute to increased consumption of the fruit in natura, enabling the product to have added value and giving the consumer a new option. The aim of this study was to assess the effect of a calcium chloride solution and a sodium alginate film on the physiology and conservation of minimally processed 'Pera' oranges. The quality of minimally processed orange submitted to treatments with 1% calcium chloride and 1% sodium alginate and the control (without treatment application) was monitored by physiologic, physical-chemical, microbiologic and sensorial analyses every three days, during storage at 5°C for a period of 12 days. The respiratory activity of the 'Pera' orange was influenced by the treatments, with the outstanding treatment being sodium alginate (1%), which was shown to be efficient for minimizing respiratory activity, as well as presenting lower psychotropic bacteria counts and lower loss of mass throughout the storage period. However, the quality of the samples submitted to this treatment was prejudiced with regard to the ascorbic acid, sugar and soluble solid contents, as well as firmness. At the end of the storage period, the treatment with calcium chloride (1%) was shown to be more efficient for maintaining the initial characteristics of the fruit, preserving the ascorbic acid content, titrable acidity, 'ratio', sugars and firmness, evidenced by less solubilization of pectins. Microbiological analysis detected insignificant total values for psychotropic bacteria, molds, yeasts and coliforms for all treatments, showing that the care taken with hygienic conditions led to obtainment of a product with a microbiologic standard in accordance with the food legislation, presenting absence of Salmonella and coliforms at 45°C. Sensorially, the minimally processed orange treated with calcium chloride (1%) and the control were shown to be in condition to be consumed for nine days of storage. When comparing the different parameters pointed out by the tasters, it could be observed that sodium alginate (1%) was outstanding as the best treatment for maintaining the sensorial quality of the minimally processed 'Pera' orange.

Texto completo da fonteResumo:
Ce travail de thèse présente le développement et la mise au point d'un procédé original pour la datation par la technique 40_Ar/39_Ar. Le cœur de ce système, un spectromètre de masse utilisant la collection simultanée des cinq isotopes de l'argon, est aujourd'hui unique à l'échelle internationale. Tout d'abord testé et validé sur des échantillons géologiques standard, ce système a permis de réaliser, dans sa configuration actuelle, des analyses de grande qualité sur les roches volcaniques de l'Ethiopie, avec une reproductibilité analytique de l'ordre de 0. 2%. Il est maintenant communément admis que les grands traps basaltiques sont en étroite relation avec les grandes déchirures continentales. C'est notamment le cas du point chaud Afar localisé dans un contexte extensif de point triple. Un des objectifs de cette thèse est d'apporter, à la lumière de 28 et 68 nouvelles données acquises, respectivement, en 40_Ar/39_Ar et K/Ar, des contraintes temporelles sur l'épanchement du point chaud et sur les prémices de l'ouverture continentale. Pour cela, des laves et des granites d'ouverture ont été échantillonnées sur les trois zones géographiques aujourd'hui désunies, c'est-à-dire sur les hauts plateaux éthiopiens, yéménites et somaliens, ainsi que le long de leurs escarpements aux marges de la dépression Afar. Nos résultats attestent de l'édification rapide des grands traps (en moins de 1 Ma, pour l'essentiel de la pile volcanique) et d'une initiation du volcanisme autour de 30. 2 Ma. Les prémices de l'ouverture apparaissent en conséquence totalement synchrones de cette phase, comme l'indique la mise en place de granites, dès 30 Ma. Les résultats de cette étude sont repris et discutés de manière plus générale, afin de préciser et de proposer un schéma global d'évolution depuis 30 MaWe present here a new analytical system for 4O_Ar/39_Ar dating that relies onto an original 180ʿ sector multiple collection mass spectrometer with five faraday cups. Results of preliminarily experiments undertaken on geological standard minerals highlight the good behavior of this new instrument for step heating analyses. The age reproducibility of successive steps lead to analytical errors lower than 0. 2 %. Such a system appears today unique on the international plan for 40_Ar/39_Ar routine dating. This new penta-collector MS enabled us to perform highly reproducible 40_Ar/39_Ar dating of Ethiopian volcanics. It is now admitted that continental flood basalt volcanism has a strong relationship with continental break-up. The Ethiopian-Afar plume has been linked to the early opening of the Afar depression, where the propagation of Red Sea and Gulf of Aden within the depression is still an ongoing process. The purposes of this study are to constrain the emplacement and duration of the trap series, and to reconstruct the eruptive chronology of the earlier opening stages, since the initiation of the fracturation. Twenty-eight 40_Ar/39_Ar and 68 K/Ar new ages data have been performed on volcanic series and granitic bodies, sampled on the plateaus (Ethiopian, Yemenite, Somalian) and along their boundaries on the Afar margin. Our results support that the onset of traps volcanism took place around 30 Ma, with a duration lower than 1 Myr. The emplacement of granitic bodies as early as 30 Ma argues for a synchronous initiation of the opening. Finally, all results obtained in this study on both plateau and rifted margin areas helped us to propose a global scheme for the evolution of the Afar depression since 30 Ma

Texto completo da fonteResumo:
Das Wurzelwachstum von Winterweizen wurde erfasst und modelliert, um teilflächenspezifisches Boden- und Düngemanagement zu verbessern. Die Variation von Wurzellängendichten im Feld wurde über zwei Vegetationsperioden hinweg an zwei unterschiedlichen Standorten in Ostdeutschland untersucht. Zur Auswertungserleichterung der hohen Anzahl an Wurzelproben, wurde eine halbautomatische Methode zur Bildanalyse von Wurzeln entwickelt. Der Einfluss von Änderungen bezüglich Bodenwasserstatus und Bodendichte bzw. Durchdringungswiderstand auf das Wurzelwachstum wurde untersucht. Die erhobenen Felddaten dienten gleichzeitig dazu, die Bodenwasser- und Wurzelwachstumsberechnung des Modells CERES-Wheat zu validieren. Das Modell simulierte die unterschiedlichen Bodeneigenschaften sowie die Wurzellängendichten und Bodenwassergehalte nur unzureichend. Der Effekt von Änderungen der Niederschlagsmengen auf die Simulationen von Wurzellängendichten und Bodenwassergehalten wurde anhand einer Unsicherheitsanalyse getestet und war extrem gering. Des Weiteren wurde eine Methode für praktische Zwecke entwickelt, mit der die Generierung von räumlich hoch aufgelösten Bodeninformationen unter Verwendung limitierter Eingangsdaten möglich ist. Die Modellkalkulationen basieren auf der Dempster-Shafer-Theorie. Anhand von multitemporal und multimodal erfassten Bodenleitfähigkeitsdaten, die Eingangsdaten für den Modellansatz sind, wurden Bodentypen und Texturklassen bestimmt. Das Modell generiert eine digitale Bodenkarte, die flächenhafte Informationen über Bodentypen und Bodeneigenschaften enthält. Die Validation der Bodenkarte mit zusätzlich erhobenen Bodeninformationen ergab gute bis sehr gute Ergebnisse.Winter wheat root growth was measured and modelled to improve site-specific soil and fertilizer management in commercial wheat fields. Field variations in root length densities were analysed at two contrasting sites in East-Germany during two vegetation seasons. A semi-automated root analysing method was developed to facilitate analyses of large numbers of samples. Influences of variations in soil water states, bulk densities and penetration resistances on spatial distributions of roots were quantified. Differences in soil characteristics were large between the two sites and affected root growth considerably. The same field data was used for validating the soil moisture and root growth calculations of the widely applied growth model CERES-Wheat. Simulations of root length densities, soil physical properties and soil water contents were inadequate. The effects of changes of rainfall variabilities on simulated root length densities and soil water contents were tested by uncertainty analysis but were negligible low. A methodology for generating soil information for practical management purposes at a high degree of spatial resolution using limited input information was developed. The corresponding model calculations were carried out based on the Dempster and Shafer theorem. Soil types and texture classes were determined with multimodally and multitemporally captured data of soil electrical conductivities which are required input data of the new model approach. The model generates a digital map with extensive information of spatial variations in soil properties. The validation of the generated soil map with soil data from independent measurements yielded close correlation between measured and calculated values.

Kadau, Renate. "Untersuchungen zu qualitätsbeeinflussenden, nacherntephysiologischen und phytopathologischen Prozessen bei Convenience-Produkten während der Kurzzeitlagerung am Beispiel von Spargel (Asparagus officinalis L.)". Doctoral thesis, Humboldt-Universität zu Berlin, Landwirtschaftlich-Gärtnerische Fakultät, 2005. http://dx.doi.org/10.18452/15327.
Texto completo da fonteResumo:
In Deutschland nimmt der Anbau von Bleichspargel (Asparagus officinalis L.) sechzehn Prozent der Gesamtgemüseanbaufläche ein. Die Qualitätssicherung von Spargel, insbesondere aber von geschältem (Convenience-) Spargel stellt wegen der hohen Stoffwechselaktivität nach der Ernte eine Herausforderung dar. Insbesondere gilt es, die Textur und die Inhaltsstoffe vor qualitätsmindernden Veränderungen und verderbsförderndem Pilzbefall zu bewahren. Als Verpackung dienen in der Regel Folienverpackungen, die aber oft für das empfindliche Gemüseprodukt nicht geeignet sind. Daher wurde der Einfluss von unterschiedlichen Folienverpackungen (vier Polypropylenfolien, zwei biologisch abbaubare Folien und ein Oberflächencoating) mit unterschiedlicher Permeabilität für Sauerstoff und Kohlendioxid auf die Veränderungen der Qualitätsparameter ( Farbe, Textur, Frischmasse, Trockensubstanz, Gerüstkohlenhydrate ( Pectine, Lignin, Hemicellulose, Cellulose, Saccharose, Fructose, Glucose) von nicht geschälten und geschälten Spargel unmittelbar nach der Ernte und nochmals nach drei (bzw. vier) Lagertagen (2°C, 10°C, 20°C Lagertemperatur) ermittelt. Direkt nach der Ernte und nach drei Lagertagen wurde bei 10°C und 20°C Lagertemperatur die Kontamination mit Pilzen und der eventuell damit verbundene Gehalt an Fumonisin B1 geprüft. Die Lagertemperatur von 10°C (2 d Lagerdauer) erwies sich als geeignet zur Qualitätserhaltung von Convenience – Spargel. Bei 2°C und 20°C geschältem Spargel waren die Pectinfraktionen, bei nicht geschältem Spargel war der Hemicellulosegehalt Veränderungen unterworfen. Die Veränderungen dieser Qualitätsparameter waren mit den Veränderungen der Textur korreliert. Die Spargelspitze ist bei der Lagerung (2°C und 20°C) stoffwechselaktiver, als die restliche Spargelstange. Es zeigte sich, dass das Verhältnis von O2 zu CO2 (RQ) in der Verpackungsfolie signifikanten Einfluss auf die Qualitätsparameter von geschältem Spargel ausübte. Die geringsten stoffwechselphysiologischen Veränderungen wurden bei einem RQ von 0,65 festgestellt. Folienverpackungen mit RQ von 0,03-0,65 hatten sich für das endophytische Pilzwachstum als hemmend erwiesen. Das Mykotoxin Fumonisin B1 wurden in gesundheitlich unbedenklichen Mengen (< 1,67 mg * kg TS-1) in nicht gelagerten und in gelagerten Spargelstangen nachgewiesen.The production area of white asparagus comprises 16 % of all vegetable crops in Germany. The economic important asparagus (Asparagus officinalis L.) is known for its high quality loss in postharvest. In order to protect convenience asparagus, i.e. fresh-cut peeled white asparagus from rapid deterioration in respect to phytopathological fungi, nutritive and sensory compounds the commercial use of film packaging might be an important tool. However, the film packaging materials used commercially do often not fulfil product physiological concerns. Therefore, the influence of different film packaging materials (four polypropylene-films, two biological degradable films and one coating) with different permeabilities for CO2 and O2 was investigated for unpeeled and peeled white asparagus during storage (2, 3, and 4 days) at temperatures of 2°C, 10°C, 20°C. Changes in the following quality attributes were studied: colour, texture, fresh weight, dry weight, structural carbohydrates (pectic substances, lignin, hemicellulose, cellulose), mono- and disaccharides (fructose, glucose, sucrose). Moreover, at harvest and after three days of storage the contamination with fungi and the content of the mycotoxin Fumonisin B1 was observed. The tests for contamination of fungi were conducted with slight nutrient agar (SNA) for seven days at 20°C under 14 h UV light and 10 h darkness (Nirenberg, 1976) Quality changes were most inhibited at a storage temperature of 10°C for two days. The ratio of O2 to CO2 (RQ) within the film packaging had a pronounced effect on the quality attributes of peeled asparagus. Changes in dry weight, fresh weight, lignin content were low at a RQ of 0,65 (P-Plus 2 film), whereas the water-soluble/insoluble pectin ratio (1 : 0,8) remained constant during the entire storage period. A low correlation was found between texture and hemicellulose, glucose, sucrose and the ratio of water-soluble to insoluble pectin. The meristematic zone of the asparagus tip revealed a higher metabolic activity than other morphological parts of the spear. Endophytic fungi, e.g. Fusarium spp., a precursor of mycotoxin, was found in control asparagus spears. During storage, the development of Fusarium spp. could be inhibited by all film packaging revealing a RQ of 0,003 - 0,65. The mycotoxin Fumonisin B1 occurred in all asparagus spears (control and stored spears), however the content (< 1,67 mg * kg TS -1) did not reach health risk threshold values.

Sugar cane is one of the crops with the highest level of water consumption, with a high evapotranspiration demand throughout most of its cycle. Knowledge of the sugar cane water demand, the time that irrigation should be applied, and how to irrigate the crop are becoming increasingly important for the sustainable development of irrigated sugar cane cultivation, especially in areas of low water availability, as it is the case in northea stern Brazil. The experiment was carried out at the Curu Experimental Field (property of the Embrapa Tropical Agroindustry), located in the Curu-Paraipaba Irrig ation Project, city of Paraipaba-CE (3 ° 29 '20''S, 39 ° 9' 45''W and elevation 30m), in order to determine the evapotrans piration and crop coefficients (Kc) of sugarcane (Saccharum L. officinarium), subsurface drip-irrigated. It was used the SP 6949 sugar cane variety, planted in a spacing of 1.8 m between double rows and 0.4 m between rows within the double row. As to t he irrigation, we used one lateral water line for each double row, buried at a depth of 0.15 m, w ith self-compensating drip emitters, with a flow rate of 1 L h-1, spaced 0.5 m on the water line. The crop was irrigated daily and there were three fertigations per week. The irrigation de pth was periodically adjusted, keeping the soil water potential between -8 kPa to -20 kPa. The crop evapotranspiration (ETc) was determined using a wei ghing lysimeter with a surface area of 2.25 m 2. The reference evapotranspiration (ETo) was estimated by the FAO Penman-Monteith method. The durations of the phenological stages of cane sugar were estimated through analysis of soil cover, with the use of digital images. Durations of 31, 49, 237 and 118 days were observed, respectively for initial, crop development, mid-season and late season stages. The yields achieved within and outside the lysimeter were respectively 144.4 and 108.8 t ha -1 . The total ETc observed during the cycle of the sugar cane was 1074.1 m m, with maximum values of 6.6 mm d-1 during the mid-season stage. Observed Kc values for initial, mid-season and late season stages were respectively 0.23, 1 .03 and 0.50. In the crop development stage, the relationship between Kc and the (crop) soil cover was represented with good accuracy by a negative quadratic model.
A cana-de-açúcar é uma das culturas com maior consumo de água, apresentando uma alta demanda evapotranspirativa ao longo da maior parte do seu ciclo. O conhecimento das necessidades hídricas da cana-de-açúcar, do momento de aplicação da água requerida pela mesma e a forma de aplicação torna-se cada vez mais importante para o desenvolvimento sustentável da sua produção irrigada, principalmente em regiões de pouca disponibilidade hídrica, como é o caso da região Nordeste do Brasil. O experimento foi conduzido no Campo Experimental do Curu, pertencente à Embrapa Agroindústria Tropical localizado no Perímetro Irrigado Curu-Paraipaba, município de Paraipaba-CE (3° 29’ 20’’ S, 39° 9’ 45’’ W e altitude de 30 m), com o objetivo de determinar a evapotranspiração e os coeficientes de cultivo (Kc) da cana-de-açúcar (Saccharum officinarium L.), irrigada por gotejamento subsuperficial. Utilizou-se a variedade de cana SP 6949, plantada no espaçamento de 1,8 m entre fileiras duplas e 0,4 m entre linhas dentro da fileira dupla. Na irrigação utilizou-se uma linha lateral para cada fileira dupla, enterrada na profundidade de 0,15 m, com gotejadores autocompensantes, com vazão de 1 L h-1, espaçados de 0,5 m na linha. A cultura foi irrigada com freqüência diária e foram realizadas três fertirrigações por semana. A lâmina de irrigação foi ajustada periodicamente, mantendo-se o potencial de água no solo entre -8 kPa e -20 kPa. A evapotranspiração da cultura (ETc) foi determinada utilizando-se um lisímetro de pesagem com área superficial de 2,25 m2. A evapotranspiração de referência (ETo) foi estimada pelo método FAO Penman-Monteith. As durações das fases fenológicas da cana-de-açúcar foram estimadas por meio da análise da cobertura do solo pela cultura, determinada com o uso de imagens digitais. Foram observadas durações de 31, 49, 237 e 118 dias, para as fases inicial, de desenvolvimento, intermediária e final, respectivamente. A produtividade alcançada dentro e fora do lisímetro foi de 144,4 e 108,8 t ha-1, respectivamente. A ETc total observada durante o ciclo da cana-de-açúcar foi de 1.074,1 mm, com valores máximos da ordem de 6,6 mm d-1 durante a fase intermediária. Foram observados valores de Kc iguais a 0,23, 1,03 e 0,50, para as fases inicial, intermediária e final, respectivamente. Na fase de desenvolvimento vegetativo a relação entre o Kc e a cobertura do solo pela cultura foi representada com bastante exatidão por um modelo quadrático negativo.

AbstractThe Khatt, Madab, and Al Ghmour Springs are important springs in UAE. They are located in the foothills of the Oman Mountains. The water temperature of these springs is relatively high (approximately 39 °C). Overexploitation of fractured aquifers negatively affected the waterflows from these springs. The outflows from these springs are time-dependent and range from 10 to 50 L/s (until 1998) to 1–10 L/s (until 2010). To assess the current conditions of the spring areas, relevant data were carefully reviewed, analyzed, and stored in a GIS database. A 3D-geological model was developed for the Khatt Springs area, which allowed different types of visualizations, calculations, and predictions. In addition, a 2D earth resistivity imaging survey was performed to evaluate the available groundwater resources, characterize the major faults/fractures feeding these springs, and to determine the locations of saturated fractures and karsts and the thicknesses of the unconsolidated materials in the wadis. Borehole and drilling information from observation wells were utilized to enhance the analysis of the earth resistivity imaging data. The described procedures and acquired results indicated that it was possible to determine the locations of two production wells for feeding Al Ghmour Springs with water during drought periods to keep it alive.

Texto completo da fonteResumo:
Water is very significant in the development of a stable community, but many societies are confronted with the challenges of poor wastes management system with indiscriminate waste disposal and bad land practices, which easily pollute water sources and consequently degrade water quality. This study was to analyze the physicochemical properties of ground water from multiple point sources in Jalingo, Taraba state of Nigeria. Water samples were collected from twenty seven (27) sites from the study area during the raining and dry seasons. The analysis was carried out to determining the physico-chemical properties of the ground water and comparing with the World Health Organization (WHO) standard for drinking water. The physicochemical properties of ground water analyzed include; odor, taste, temperature and electrical conductivity were tested in the field using water meter tester. Whereas pH, total dissolved solids, alkalinity, hardness, salinity, iron, manganese, fluoride, nitrate, nitrite, chloride, sulphate and dissolved oxygen were analyzed in the laboratory using Wagtech potable water testing equipment. The physical properties of water analyzed were temperature, odor, taste, and turbidity. Whereas the chemical properties of water analyzed were pH, electrical conductivity (EC), total dissolved solids (TDS), alkalinity, hardness, salinity, iron (Fe), manganese (Mn), fluoride (F−), nitrate (NO3−), nitrite (NO2−), Chloride (Cl−), sulphate (SO42−), dissolved oxygen (DO).The result shows the range of the mean values of the temperature(26.7–33.1) oC, p H(6.5–8.9), Fe (0.01–0.08 mg/L), NO3−(0.01–38.5 mg/l), NO2−(0.01–0.09 mg/l), Mn (0.01–0.17 mg/l), F(0.01–0.82 mg/l), alkalinity(39-204 mg/l), salinity (42-508 mg/l), SO4(14-93 mg/l), total dissolved solids (6–637) mg/l, turbidity(0.4–10.6 mg/l), hardness(48-187 mg/l), and fecal coliforms(1–4)fcu/100mi, dissolved oxygen(1.1–6.87)mg/l, EC(10.99–1066)ohm/cm, Cl (10-320 mg/l). All except alkalinity and hardness are within the WHO permissible standards of quality drinking water. The highest alkalinity (204 mg/l), hardness (187 mg/l) and low dissolved oxygen (6.87 mg/l) attributed to the high concentration of dissolved salts and basic cations in the water. The methodology applied in the study was effective in analyzing the physicochemical properties of water in the study area. Therefore, it was recommended that there should be frequent water source testing by stakeholder in water resources with the view to treating the water. Policy maker should also enforce the regulation of the use of chemical fertilizers, agro-chemicals and the indiscriminate waste disposal.

<em>Abstract</em>.—Over the past 15 years, the California Department of Fish and Game has monitored applications of the rotenone formulations Nusyn-Noxfish<sup>®</sup> (synergized liquid formulation) and Pro-Noxfish<sup>®</sup> (powdered formulation) to lakes and streams. The monitoring studies were designed to limit liability and address environmental and public health issues. Results indicated that (a) the half-life (t<sub>½</sub>) of rotenone increased inversely with temperature from 0.6 to 7.7 days; (b) the degradation product rotenolone was generally not found in the absence of rotenone, except in waters of low alkalinity (<15 mg/L CaCO<sub>3</sub>) and temperature (<11°C); (c) Nusyn-Noxfish® contaminant trichloroethylene (up to 4.9 μg/L) and additive xylene (up to 6.7 μg/L) were found typically only in lakes; (d) Nusyn-Noxfish® additives naphthalene (up to 332 μg/L) and methylnaphthalenes (up to 390 μg/L) were found in both lakes and streams; (e) potassium permanganate can neutralize rotenone within a contact time of 30 minutes; (f) Nusyn-Noxfish® synergist piperonyl butoxide can persist in cold (<10°C) and deep (>25 m) waters for up to nine months; and (g) ground water remained free of chemicals in both rotenone formulations. These studies demonstrated that (a) toxicity and other effects can be confined to the treatment and neutralization areas; (b) concentrations of chemicals in surface waters (with the exception of rotenolone and piperonyl butoxide in cold waters) persist for less than seven weeks; (c) rotenone, naphthalene, and methylnaphthalene persist in sediments for short periods; and (d) ground waters were not contaminated.

Abstract Her hesitancy apparently yielded to the incandescent delight of the first quotation. In the image of Sackville-West ‘stalking’ above her, legs like trees, Woolf recalls the unexpected angles from which the body of a lover is viewed. Her final phrases seem a kind of sexual tongue-twisting, rolling the words in the mouth: ‘pink glowing, grape clustered, pearl hung’. Woolf’s letters were sometimes even more explicit: you only be a care ful dolphin in your gambolling, or you’ll find Virginia’s soft crevices lined with hooks!’ (Woolf to Sackville-West, L, iii. 395, 4 July 1927). Sexual and linguistic play were intertwined.

Since the early 1980s, aldol condensations involving boron enolates have gain great importance in asymmetric synthesis, particularly the synthesis of natural products with adjacent stereogenic centers bearing hydroxyl and methyl groups. (Z)-Boron enolates tend to give a high diastereoslectivity preference for the syn-stereochemistry while (E)-boron enolates favor the anti-stereochemistry. Because the B-O and B-C bonds are shorter than other metals with oxygen and carbon, the six membered Zimmerman–Traxler transition state in the aldol condensation tends to be more compact which accentuates steric interactions, thus leading to higher diastereoselectivity. When this feature is coupled with a boron enolate bearing a chiral auxillary, high enantioselectivity is achieved. Boron enolates are generated from a ketone and boron triflate in the presence of an organic base such as triethylamine. Reviews: (a) Abiko, A. Acc. Chem. Res. 2004, 37, 387-395. (b) Cowden, C. J.

The object of the research of the paper is to design a reference model of an unmanned aircraft according to the model of the training jet Aero L 39. The work contains an analysis of the methods, procedures and typology used in the creation of reference models. Subsequently, the design of an unmanned vehicle was created using computer modelling, which was subjected to aerodynamic simulations and strength analysis. Aerodynamic performance was investigated on the airframe of the aircraft and strength analyses were determined on specific structural elements. After successful program tests, a functional model of the aircraft was built. The prerequisite was mainly aerodynamic analyses, which should determine with sufficient accuracy the basic structure of the model's flight. The result of solving the problem is a functional model of the aircraft, which is suitable for flight tests using appropriate hardware.

The work examines the results of the dynamics of biological diversity of living ground cover in connection with thinning in young stands of lingonberry pine forests. The species diversity of the living ground cover of the lingonberry pine forest amounted to 25 species. 21 species participate in the composition of the herb-shrub layer, the total projective cover of which is about 23%. The main ground cover plants that achieve the highest quantitative indicators are Vaccinium vitis-idaea L., Vaccinium myrtillus L., Calluna vulgaris (L.) Hill, Festuca ovina L. Most species are characterized by a low occurrence of 5–10%. The moss-lichen layer is poorly expressed, their specific weight in the composition of the ground cover is low. The total projective coverage is about 2%. The species composition is represented by two species of mosses Pleurozium schreberi (Brid.) Mitt., and Polytrichum juniperinum Hedw. and two species of lichen Cladonia rangiferina (L.) Web. and Cladonia sylvatica (L.) Hoffm.). Analysis of the species composition and structure of the living ground cover of the lingonberry pine forest after thinning showed that the total projective cover of the grass-shrub layer increases to 39%.

Texto completo da fonteResumo:
Yellow rust, caused by Puccinia striiformis Wes. is one of the most significant diseases constraint to winter wheat production in the world. Since 2011 in Europe have appeared distinct new races – Warrior, Kranich, Warrior (-) that have caused wide epidemics on different cultivars of wheat. Grain yield losses can be prevented by using a combination of varietal resistance and fungicides. Information on wheat variety susceptibility to local yellow (stripe) rust Puccinia striiformis Wes. races can help to reduce the risk of yield losses in high disease pressure situations. Field trials with eight most popular and perspective winter wheat varieties in Latvia were established in the North-Western part of Latvia (Stende Research Centre) in autumn of 2016. The trial was designed as two randomized complete blocks (treated and untreated) and data were statistically interpreted. Two applications of fungicides at BBCH 29-32 by T1 (prothioconazol 53 g L-1, spiroxamin 224 g L-1, tebucanazole 148 g L-1) and at BBCH 37-39 - T2 (bixafen 65 g L-1, prothioconazol 130 g L-1, fluopyram 65 g L-1- 1.5 L ha-1) were used to control the YR. Yield and 1000 kernel weight (TKW) were determined. Preliminary results indicated the difference between genotypes resistance/susceptibility to YR. The severity of infection level was 1- 80% depending on genotype resistance. Application of fungicides increased grain yield by 2.9 % to 33.0% and TKW by 3.4% - 33.2 % depending on variety. Observations showed the difference in the occurrence of symptoms on YR in different varieties of winter wheat under conditions of 2017 in Stende.

Texto completo da fonteResumo:
Laboratory activities for testing nitrogen levels of natural rubber production are carried out to determine the nitrogen content to meet the Standard Indonesian Rubber (SIR). The test parameters use hazardous chemicals such as strong acids, i.e. sulfuric acid, which have corrosive properties. Testing activities in the laboratory will produce by-products in the form of liquid wastewater containing high sulfate concentrations. A cheap and environmentally friendly wastewater treatment system is required in this research, namely a coagulation-flocculation system using eco-enzyme as a liquid coagulant. Eco-enzyme is a fermented product of household organic waste from the remaining vegetables and fruit peels that are still fresh with a 1:3:10 formula after around 3 months. The purpose of this research was to determine the levels of COD, TDS, and sulfate concentrations as an indicator of wastewater quality standards that are safe for the environment. It is necessary to know the effectiveness of the eco-enzyme as a coagulant in treating laboratory wastewater with various concentrations of 1, 5, 10, 20, and 40% v/v. As well as variations in monitoring time of 5, 10, 15, 20, and 30 days. In this study, laboratory waste treatment with Eco-Enzyme as a coagulant resulted in a decrease in sulfate levels at 29.8 mg/L found at 1% v/v Eco-Enzyme concentration with monitoring for 30 days. With levels of COD 263 mg/L, TDS 39.7 mg/L, and pH 7.01 at a concentration of 40% v/v Eco-Enzyme. The results of this study indicate that Eco-Enzyme can act as a natural coagulant that is environmentally friendly and can degrade laboratory liquid waste so that it meets wastewater quality standards that are safe for the environment.

Texto completo da fonteResumo:
Успешность интродукции растений определяется одним из важнейших показателей – способностью вида к естественному возобновлению за пределами ареала [3,4]. Установлено, что некоторые виды клёнов способны к самовозобновлению семенами, но при продвижении в более суровые климатические условия число таких таксонов сокращается [7]. Самым активным видом в данном случае является Acer negundo L. - отмечается как агрессивный вид, натурализовавшийся во многих регионах Северной Евразиии [5]. Согласно данным, приведённым в литературных источниках, в Узбекистане большинство интродуцированных клёнов дают самосев [3]. Например, для Acer platanoides L. здесь установлены следующие показатели возобновления 50-60 шт./ м2; на Украине - 14-22 шт./ м2. Большая часть всходов гибнет из-за засушливого климата. По городам России подобных данных очень мало. В Санкт-Петербурге самосев отмечен у 14 видов клёна [9], в Москве и Подмосковье – у 4 видов [2, 1, 6], в Ростове-на-Дону самосевом размножаются 8 таксонов рода Acer L. [8]. В Архангельске самосев характерен для Acer platanoides L. и Acer schwedleri K.Koch. Acer negundo L. в данных климатических условиях самосева не имеет и обладает низким качеством семян (39-20 %), что исключает угрозу биологической инвазии. При обследовании участков в дендрологическом саду имени И.М. Стратоновича и в условиях города, на которых произрастают изучаемые клёны, были обнаружены многочисленные всходы, что положительно характеризует их по степени адаптации к местным условиям. Данные виды не образуют спонтанных фитоценозов в условиях интродукции. С целью изучения степени самовозобновления данных видов в дендрарии были заложены пробные площадки (1м2) в трёхкратной повторности на расстоянии от 1 до 6 м от маточных деревьев. Таким образом, на исследуемых площадках произрастают растения разного возраста от 1 до 10 лет. Число исследуемых особей на пробных площадках варьировало от 4 до 30 шт. У подроста замеряли высоту (длину стебля), см; диаметр осевого побега у шейки корня, мм; длину корня, см; годичный прирост побегов, см и определяли возраст по междоузлиям стебля. Согласно полученным данным, установлено, что средний возраст подроста в дендрарии (3 года) ниже, чем в условиях города (6 лет). Это обусловлено тем, что в дендросаду регулярно проводятся работы по покосу травы и выкопке и пересадке растений – большинство всходов гибнут. В городских же условиях площадки закладывались в труднодоступном для покоса месте. Коэффициент вариации свидетельствует о сильном разнообразии вариационного ряда (39,12 – 61,08%). В ходе исследований нами установлено, что у подроста наблюдается стабильный ежегодный прирост, они не обмерзают и по текущему приросту одревесневают на 100 %, зимний период не оказывает негативного влияния на их жизнеспособность, что подтверждает высокие адаптационные способности изучаемых таксонов. Вопросы семенного самовозобновления клёнов в условиях Архангельска рассматривались впервые.

United States Department of Agriculture, setembro de 2003. http://dx.doi.org/10.32747/2003.7587222.bard.
Texto completo da fonteResumo:
The overall objective of the whole research was to elucidate the mechanisms by which LAB silage inoculants enhance ruminant performance. The results generated will permit the development of better silage inoculants that maximize both silage preservation and animal performance. For this one-year BARD feasibility study, the objectives were to: 1. determine whether lactic acid bacteria (LAB) used in inoculants for silage can survive in rumen fluid (RF) 2.select the inoculants that survived best, and 3. test whether LAB silage inoculants produce bacteriocins-like substances. The most promising strains will be used in the next steps of the research. Silage inoculants containing LAB are used in order to improve forage preservation efficiency. In addition, silage inoculants enhance animal performance in many cases. This includes improvements in feed intake, liveweight gain and milk production in 25-40% of studies reviewed. The cause for the improvement in animal performance is not clear but appears to be other than direct effect of LAB inoculants on silage fermentation. Results from various studies suggest a possible probiotic effect. Our hypothesis is that specific LAB strains interact with rumen microorganisms which results in enhanced rumen functionality and animal performance. The first step of the research is to determine whether LAB of silage inoculants survive in RF. Silage inoculants (12 in the U.S. and 10 in Israel) were added to clarified and strained RF. Inoculation rate was 10 ⁶ (clarified RF), 10⁷ (strained RF) (in the U.S.) and 10⁷, 10⁸ CFU ml⁻¹ in Israel (strained RF). The inoculated RF was incubated for 72 and 96 h at 39°C, with and without 5 g 1⁻¹ glucose. Changes in pH, LAB numbers and fermentation products were monitored throughout the incubation period. The results indicated that LAB silage inoculants can survive in RF. The inoculants with the highest counts after 72 h incubation in rumen fluid were Lactobacillus plantarum MTD1 and a L. plantarum/P. cerevisiae mixture (USA) and Enterococcus faecium strains and Lactobacillus buchneri (Israel). Incubation of rumen fluid with silage LAB inoculants resulted in higher pH values in most cases as compared with that of un-inoculated controls. The magnitude of the effect varied among inoculants and typically was enhanced with the inoculants that survived best. This might suggest the mode of action of LAB silage inoculants in the rumen as higher pH enhances fibrolytic microorganisms in the rumen. Volatile fatty acid (VFA) concentrations in the inoculated RF tended to be lower than in the control RF after incubation. However, L. plalltarull1 MTDI resulted in the highest concentrations of VFA in the RF relative to other inoculants. The implication of this result is not as yet clear. In previous research by others, feeding silages which were inoculated with this strain consistently enhanced animal performance. These finding were recently published in Weinberg et.al.. (2003), J. of Applied Microbiology 94:1066-1071 and in Weinberg et al.. (2003), Applied Biochemistry and Biotechnology (accepted). In addition, some strains in our studies have shown bacteriocins like activity. These included Pediococcus pentosaceus, Enterococcus faecium and Lactobacillus plantarum Mill 1. These results will enable us to continue the research with the LAB strains that survived best in the rumen fluid and have the highest potential to affect the rumen environment.

Texto completo da fonteResumo:
Climate and hydrology are major drivers of ecosystems. They dramatically shape ecosystem structure and function, particularly in arid and semi-arid ecosystems. Understanding changes in climate, groundwater, and water quality and quantity is central to assessing the condition of park biota and key cultural resources. The Sonoran Desert Network collects data on climate, groundwater, and surface water at 11 National Park Service units in southern Arizona and New Mexico. This report provides an integrated look at climate, groundwater, and springs conditions at Chiricahua National Monument (NM), Coronado National Memorial (NMem), and Fort Bowie National Historic Site (NHS) during water year (WY) 2019 (October 2018–September 2019). Overall annual precipitation at Chiricahua NM and Coronado NMem in WY2019 was approximately the same as the normals for 1981–2010. (The weather station at Fort Bowie NHS had missing values on 275 days, so data were not presented for that park.) Fall and winter rains were greater than normal. The monsoon season was generally weaker than normal, but storm events related to Hurricane Lorena led to increased late-season rain in September. Mean monthly maximum temperatures were generally cooler than normal at Chiricahua, whereas mean monthly minimum temperatures were warmer than normal. Temperatures at Coronado were more variable relative to normal. The reconnaissance drought index (RDI) indicated that Chiricahua NM was slightly wetter than normal. (The WY2019 RDI could not be calculated for Coronado NMem due to missing data.) The five-year moving mean of annual precipitation showed both park units were experiencing a minor multi-year precipitation deficit relative to the 39-year average. Mean groundwater levels in WY2019 increased at Fort Bowie NHS, and at two of three wells monitored at Chiricahua NM, compared to WY2018. Levels in the third well at Chiricahua slightly decreased. By contrast, water levels declined in five of six wells at Coronado NMem over the same period, with the sixth well showing a slight increase over WY2018. Over the monitoring record (2007–present), groundwater levels at Chiricahua have been fairly stable, with seasonal variability likely caused by transpiration losses and recharge from runoff events in Bonita Creek. At Fort Bowie’s WSW-2, mean groundwater level was also relatively stable from 2004 to 2019, excluding temporary drops due to routine pumping. At Coronado, four of the six wells demonstrated increases (+0.30 to 11.65 ft) in water level compared to the earliest available measurements. Only WSW-2 and Baumkirchner #3 have shown net declines (-17.31 and -3.80 feet, respectively) at that park. Springs were monitored at nine sites in WY2019 (four sites at Chiricahua NM; three at Coronado NMem, and two at Fort Bowie NHS). Most springs had relatively few indications of anthropogenic or natural disturbance. Anthropogenic disturbance included modifications to flow, such as dams, berms, or spring boxes. Examples of natural disturbance included game trails, scat, or evidence of flooding. Crews observed 0–6 facultative/obligate wetland plant taxa and 0–3 invasive non-native species at each spring. Across the springs, crews observed six non-native plant species: common mullein (Verbascum thapsus), spiny sowthistle (Sonchus asper), common sowthistle (Sonchus oleraceus), Lehmann lovegrass (Eragrostis lehmanniana), rabbitsfoot grass (Polypogon monspeliensis), and red brome (Bromus rubens). Baseline data on water quality and water chemistry were collected at all nine sites. It is likely that that all nine springs had surface water for at least some part of WY2019, though temperature sensors failed at two sites. The seven sites with continuous sensor data had water present for most of the year. Discharge was measured at eight sites and ranged from < 1 L/minute to 16.5 L/minute.

Survey of health and social care setting food businesses on implementation of the FSA Listeriosis Guidance. Food Standards Agency, maio de 2023. http://dx.doi.org/10.46756/sci.fsa.djg946.
Texto completo da fonteResumo:
Food safety is a crucial component of protecting the wellbeing of those in the care of health and social care organisations. Incidents, such as the 2019 listeriosis outbreak associated with pre-packed sandwiches supplied to hospitals in England, from which seven patients died of listeriosis, underline the risk of the disease and the serious consequences that a breach in standards can have. Vulnerable consumers - whose immune systems are weakened in some way - are particularly susceptible to listeriosis and the disease has a high hospitalisation and fatality rate, compared to infections with other bacterial pathogens. The bacterium which causes listeriosis, Listeria monocytogenes, is acutely challenging to control as it has the potential to grow at low temperatures and can survive freezing. As such, L. monocytogenes must be controlled in any health or social care (HSC) organisation that provides chilled ready-to-eat food for vulnerable groups. The Food Standards Agency (FSA) guidance on ‘Reducing the risk of vulnerable groups contracting listeriosis (Opens in a new window)’ concentrates on preventing the spread of listeriosis, from preparation to consumption, in chilled ready-to-eat food. The review set up following the 2019 listeriosis outbreak - the Independent Review of NHS Hospital Food (Opens in a new window), contained recommendations on food safety for NHS trusts to take on board. The FSA also committed to assess its own guidance in response to the 2019 outbreak. Social research was commissioned as part of the FSA’s response. This report covers findings from 39 respondents within NHS Trusts and 445 from Health and Social Care (HSC) (non- NHS Trust) settings, such as nursing homes, home care service providers and hospices, in England, Wales and Northern Ireland. The research objectives for the surveys of health and social care settings and NHS Trusts were to: Measure awareness of the FSA guidance on listeriosis Find out how well the FSA guidance on listeriosis is implemented Understand barriers to implementing the guidance in full Understand good practice in implementing the guidance Understand HSC stakeholders’ perceptions of the effectiveness and suitability of the guidance
