Abstract. An ensemble of space-borne and ground-based instruments has been used to evaluate the quality of the version 2.2 temperature retrievals from the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS). The agreement of ACE-FTS temperatures with other sensors is typically better than 2 K in the stratosphere and upper troposphere and 5 K in the lower mesosphere. There is evidence of a systematic high bias (roughly 3–6 K) in the ACE-FTS temperatures in the mesosphere, and a possible systematic low bias (roughly 2 K) in ACE-FTS temperatures near 23 km. Some ACE-FTS temperature profiles exhibit unphysical oscillations, a problem fixed in preliminary comparisons with temperatures derived using the next version of the ACE-FTS retrieval software. Though these relatively large oscillations in temperature can be on the order of 10 K in the mesosphere, retrieved volume mixing ratio profiles typically vary by less than a percent or so. Statistical comparisons suggest these oscillations occur in about 10% of the retrieved profiles. Analysis from a set of coincident lidar measurements suggests that the random error in ACE-FTS version 2.2 temperatures has a lower limit of about ±2 K.

Abstract Angiotensin I converting enzyme (ACE) inhibitory peptides derived from milk proteins have obvious effect of lowering blood pressure, safe and non-toxic side effects. This study compared four commercial proteases, namely alcalase, flavourzyme, neutral protease and proteinase K for their ACE inhibitory activity in skimmed goat and cow milk and identified the best one with higher ACE inhibitory activity. The degree of hydrolysis (DH) of alcalase and proteinase K were much higher than flavourzyme, neutral protease for both skimmed goat and cow milk. Alcalase was the best enzyme to produce ACE inhibitory peptides from goat milk, with the ACE inhibitory activity 95.31%, while proteinase K was the optimal protease for hydrolyzing cow milk, with 81.28% ACE inhibitory activity. Furthermore, no correlation was obtained between the ACE inhibitory activity and DH for both goat and cow milk.

Full textAbstract:
The current case report represents a warning against serious hyperkalaemia and acidosis induced by ACE-I during surgical stress while normal renal function could deceive the attending anaesthetist. Arterial gas analysis for follow-up of haemoglobin loss accidentally discovered hyperkalaemia and acidosis. Glucose-insulin and furosemide successfully corrected hyperkalaemia after 25 minutes and acidosis after 3 hours. These complications could be explained by a deficient steroid stress response to surgery secondary to suppression by ACE-I. Event analysis and database search found that ACE-I induced aldosterone deficiency aggravated by surgical stress response with an inadequate increase in aldosterone secretion due to angiotensin II deficiency as a sequel of ACE-I leading to defective secretion of H+ and K+. Furosemide is recommended to secrete H+ and K+ compensating for aldosterone deficiency in addition to other antihyperkalaemia measures. Anaesthetising an ACE-I treated patient requires considering ACE-I as a potential cause of hyperkalaemia and acidosis.

Full textAbstract:
Climate sensitivity and feedback processes are important for understanding Earth’s system response to increased CO2 concentration in the atmosphere. Many modelling groups that contribute to Coupled Model Intercomparison Project phase 6 (CMIP6) have reported a larger equilibrium climate sensitivity (ECS) with their models compared to CMIP5 models. This consistent result is also found in the Korea Meteorological Administration Advanced Community Earth System model (K-ACE). Idealized climate simulation is conducted as an entry card for CMIP6 to understand Earth’s system response in new coupled models and compared to CMIP5 models. The ECS in the K-ACE is 4.83 K, which is higher than the range (2.1–4.7 K) of CMIP5 models in sensitivity to CO2 change and higher bound (1.8–5.6 K) of CMIP6 models. The radiative feedback consists of clear-sky and cloud radiative feedback. Clear-sky feedback of K-ACE is similar to CMIP5 models whereas cloud feedback of K-ACE is more positive. The result is attributable for strong positive shortwave cloud radiative effect (CRE) feedback associated with reduced low-level cloud cover at mid latitude in both hemispheres. Despite the cancellations in strong negative long wave CRE feedback with the changes in high-level clouds in the tropics, shortwave CRE has a dominant effect in net CRE. Detailed understanding of cloud feedback and cloud properties needs further study.

ACE.2 mice lack all tissue angiotensin-converting enzyme (ACE) but have 33% of normal plasma ACE activity. They exhibit the urine-concentrating defect and hyperkalemia present in mice that lack all ACE, but in contrast to the complete knockout, ACE.2 mice have normal medullary histology and creatinine clearance. To explore the urine-concentrating defect in ACE.2 mice, renal medullary transport proteins were analyzed using Western blot analysis. In the inner medulla, UT-A1, ClC-K1, and aquaporin-1 (AQP1) were significantly reduced to 28 ± 5, 6 ± 6, and 39 ± 5% of the level in wild-type mice, respectively, whereas AQP2 and UT-B were unchanged. In the outer medulla, Na+-K+-2Cl− cotransporter (NKCC2/BSC1) and AQP1 were significantly reduced to 56 ± 11 and 29 ± 6%, respectively, whereas Na+-K+-ATPase, UT-A2, UT-B, and AQP2 were unchanged, and renal outer medullary potassium channel was significantly increased to 711 ± 187% of the level in wild-type mice. The abnormal expression of these transporters was similar in ACE.2 mice backcrossed onto a C57BL/6 or a Swiss background and was not rescued by ANG II infusion. We conclude that the urine-concentrating defect in ACE.2 mice is associated with, and may result from, downregulation of some or all of these key urea, salt, and water transport proteins.

Abstract. Motivated by the initial selection of a high-resolution solar occultation Fourier transform spectrometer (FTS) to fly to Mars on the ExoMars Trace Gas Orbiter, we have been developing algorithms for retrieving volume mixing ratio vertical profiles of trace gases, the primary component of which is a new algorithm and software for retrieving vertical profiles of temperature and pressure from the spectra. In contrast to Earth-observing instruments, which can rely on accurate meteorological models, a priori information, and spacecraft position, Mars retrievals require a method with minimal reliance on such data. The temperature and pressure retrieval algorithms developed for this work were evaluated using Earth-observing spectra from the Atmospheric Chemistry Experiment (ACE) FTS, a solar occultation instrument in orbit since 2003, and the basis for the instrument selected for a Mars mission. ACE-FTS makes multiple measurements during an occultation, separated in altitude by 1.5–5 km, and we analyse 10 CO2 vibration–rotation bands at each altitude, each with a different usable altitude range. We describe the algorithms and present results of their application and their comparison to the ACE-FTS data products. The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) provides vertical profiles of temperature up to 40 km with high vertical resolution. Using six satellites and GPS radio occultation, COSMIC's data product has excellent temporal and spatial coverage, allowing us to find coincident measurements with ACE with very tight criteria: less than 1.5 h and 150 km. We present an intercomparison of temperature profiles retrieved from ACE-FTS using our algorithm, that of the ACE Science Team (v3.5), and from COSMIC. When our retrievals are compared to ACE-FTS v3.5, we find mean differences between −5 and +2 K and that our retrieved profiles have no seasonal or zonal biases but do have a warm bias in the stratosphere and a cold bias in the mesosphere. When compared to COSMIC, we do not observe a warm/cool bias and mean differences are between −4 and +1 K. COSMIC comparisons are restricted to below 40 km, where our retrievals have the best agreement with ACE-FTS v3.5. When comparing ACE-FTS v3.5 to COSMIC we observe a cold bias in COSMIC of 0.5 K, and mean differences are between −0.9 and +0.6 K.

Full textAbstract:
Angiotensin-converting enzyme (ACE) inhibitors can reduce cardiac mass in both clinical and experimental cardiac hypertrophy. Because cytoplasmic Na+ and pH have been implicated as regulators of cell growth, we examined the effect of treatment with an ACE inhibitor on intracellular Na+ activity (alpha iNa) and pH (pHi) in the heart. After treatment of rabbits with captopril for 8 days alpha iNa was reduced relative to controls (3.6 +/- 0.4, n = 8, vs. 8.2 +/- 0.4 mM, n = 9, P < 0.001), whereas pHi was unchanged. To account for the difference in alpha iNa we measured electrogenic Na(+)-K+ pump activity in single isolated myocytes. Treatment with captopril increased pump currents at near-physiological levels of intracellular Na+ but had no effect at near-saturating levels of Na+. A similar increase in Na(+)-K+ pump activity occurred in rabbits treated with another ACE inhibitor, enalapril, but not with the vasodilator, hydralazine. We speculate that a decrease in alpha iNa after treatment with captopril may contribute to the well-documented ability of ACE inhibitors to reduce cardiac mass.

The Bioconcentration Factor (BCF) is the principal source of information used to assess and regulate the potential hazard and risk for a chemical that has the potential to bioaccumulate in the marine environment, according to the Marine Strategy Framework Directive (MSFD). The main objective of this thesis was to estimate the BCFs of two different emerging contaminants in Ruditapes philippinarum (Manila clam) under controlled laboratory conditions: the UV filter 4-methylbenzylidene camphor (4-MBC) commonly used in skincare products, and the artificial sweetener Acesulfame potassium (ACE-K) used as a food additive. Ruditapes philippinarum organisms were exposed directly to 4-MBC and ACE-K nominal concentration of 1, 10 and 100 μg L-1 during 10 days. Bioconcentration factors (BCFs) were estimated according to 3 different models for both compounds. The 4-MBC estimated BCFs fall in range of 61553 - 539143 L Kg-1, showing that this compound is very bioaccumulative and could also undergo biomagnification in the marine food chain. On the contrary, estimated ACE-K BCF is consistently lower, in order of 7 L Kg-1 for the nominal exposure concentration of 100 μg L-1. The low ACE-K BCF could be explained by its high solubility in water and thus a rapid metabolization by clams during the experiments. In summary, future research focusing on the marine environment is needed on these two emerging compounds.

The consumer today is affected by a considerably larger number of world surrounding factors than she used to be, borders between different cultures and other consumer differences are being erased to a growing extent. The consumer can easily get its inspiration from many different directions which become clear in the common life. We eat sushi for lunch, we’re driving German cars and we’re having dinner with international business partners. The community also exposes the consumer for a more intense noise from offers, impact and marketing. Never before have so many different actors on the market been competing about the consumers’ attention. In a community where the noise constantly grow more and more intense, the importance of the product function is decreasing to make room for an increasing importance of the brand’s position on the market. The customer no longer buys a garment for its function, but for image or perhaps even the personality it brings along. Acne Jeans and Filippa K are two successful Swedish companies that are established in both Stockholm and Gothenburg. Both of these trademarks offer the customer a lifestyle instead of just a simple product. The purpose of this study is to examine, describe and analyze what Acne Jeans and Filippa K wants to provide with their trademarks and how the customer see these brands concerning consumer buying behavior and attitude. The study will be seen partially from a sender perspective and partially from a receiver perspective. In this essay we have used a human-hermeneutic way of interpretation. We have conducted a qualitative study of how Acne Jeans and Filippa K want to provide their trademarks and what the consumers think about the both brands in Stockholm and Gothenburg. The empiric material in our essay consists of observations of Acne Jeans and Filippa K, and interviews with consumers in both Stockholm as well as in Gothenburg. Through our research we have achieved the conclusion that Acne Jeans wants trough its trademark provide fashionable garments to the customers. The respondents that have made themselves an opinion about the company have a positive image of Acne Jeans. The respondents whom cannot identify themselves with Acne Jeans have a more negative attitude to the company. In Gothenburg the customer has a stronger relationship to the trademark than the Stockholm respondents.Filippa K wants through its trademark provide timeless clothing of high quality to a commercial price to the customers. All the respondents were familiar with the trademark and in one way or another had a connection and relationship with the company. Regardless of age, respondents in both Stockholm and Gothenburg had a positive attitude towards the company; the customer has a high rank of awareness to Filippa K. The associations to the brand are strong and the consumer has a mentally loyal attitude towards Filippa K.Program: Textilekonomutbildningen

Full textAbstract:
Depuis le milieu du XXe siècle, l'arbitrage commercial international a connu un développement phénoménal et acquis une importance significative dans le monde des transactions commerciales internationales. Il est effectivement devenu la juridiction mondiale la plus acceptable, la plus fiable et la plus usuelle pour résoudre les différends relatifs au commerce et aux investissements internationaux. Toutefois, il a rencontré des difficultés en ce qui concerne les mesures provisoires et conservatoires ce qui explique la tendance des parties à éviter d’y avoir recours devant les arbitres, au profit des juridictions étatiques pour obtenir les mesures d’urgence dont ils avaient immédiatement besoin. L’inexistence d’un régime procédural capable de bien régir cette matière était la raison principale qui a réduit l’efficacité de l’arbitrage. Pourtant, ce fait a changé grâce aux modifications majeures qui ont été apportées à la Loi type de la CNUDCI en 2006. Cette loi a établi un régime arbitral spécifique aux mesures provisoires et conservatoires. À un stade ultérieur, les règlements modifiés récemment par les centres d’arbitrage qui agissent sur la scène internationale ont beaucoup développé ce régime en le mettant en pratique. Maintenant, en présence d’un régime arbitral particulier régissant les mesures provisoires et conservatoires, il est opportun d’en évaluer en profondeur l’efficacité par rapport à celle du régime étatique classique régissant la même matière. Voilà l’objectif de cette thèse de doctorat qui présente nombre des propositions doctrinales et normatives dans le but d’améliorer autant que possible ce régime arbitral récent.Since the mid-twentieth century, the International Commercial Arbitration has achieved massive development and has gained significant importance in the world of international business transactions. It has effectively become the most acceptable, reliable and widely preferred jurisdiction for the settlement of international investment and trade disputes. However, for a long time, the failure of arbitration to properly deal with interim measures lead adversaries to avoid resorting to arbitral tribunals preferring the state courts when emergency measures were required. The main reason for this inadequacy was the lack of a comprehensive arbitral regime for governing the interim measures procedure, which in turn lead to a reduction in the effectiveness of international arbitration. This issue was recently addressed thanks to the major amendments to the UNCITRAL Model Law in 2006. This Model Law established a specialized regime to govern the arbitral proceedings for interim measures. More recently, a number of prominent international arbitration centers modified their rules to comprehensively deal with the issue of interim measures and to put it into practice. The introduction of this specialized arbitral regime calls for more effort to evaluate and compare its effectiveness to the juridical state system in dealing with the issue of interim measures. Therefore, the main objective of this doctoral thesis is to provide a thorough and analytical comparison of the two systems and to present a number of doctrinal and legislative proposals aimed at improving the recently introduced arbitral regime.

Sammanfattning Elförsörjning är en av samhällets mest vitala funktioner och el förbrukas daligen av konsumenter. För att konsumentens ska kunna elförsörjas krävs det bland annat att denne ingår avtal om köp av el med elhandelsbolaget. Avtalet ålägger konsumenten en betalningsskyldighet för den förbrukade elen. Försummar konsumenten sin betalningsskyldighet kan elhandelsbolaget, i enlighet med 11 kapitlet ellagen och avtalet, vara berättigat att vidta avbrott i elöverföringen. För att rätten till avbrott i elöverföringen ska få vidtas krävs att vissa förutsättningar är uppfyllda. Dessa förutsättningar utgör en del av konsumentskyddet på elmarkanaden och elhandelsbolaget hindras därmed från att hur som helst vidta avbrott i elöverföringen. Detta konsumentskydd består av ett antal förutsättningar och är alla förutsättningar inte uppfyllda får avbrott i elöverföringen inte vidtas. Exempel på när avbrott i elöveföringen inte får vidtas är när socialnämnden åtar sig betalningsansvaret för elskulden. I realiten torde enbart vissa ekonomiskt utsatta konsumenter beröras av bestämmelserna om avbrott i elöverföringen. Därmed torde socialnämndens betalningsåtagande vara avgörande för dennes fortsatta rätt till el. Socialnämnden beviljar enbart ekonomiskt bistånd som sista möjliga utväg. Därmed kommer enbart vissa av de ekonomiskt utsatta konsumenterna att behålla rätten till el medan övriga berövas denna rätt. Elhandelsbolagets rätt till avbrott i elöverföringen tillförsäkras redan genom lag vilket innebär att standardavtalet är överflödigt. Avtalets grundläggande funktion är att kunna garantera att konsumenten betalar. Därmed bör konsumentens betalningsskyldighet lagstadgas.Abstract Electricity supply is one of society's most vital functions and electricity is daily consumed by consumers. To be supplied with electricity the consumer must enter into a contract agreement with the electricity trading company. The contract imposes the consumer to pay for the consumed electricity. If the consumer neglects to pay the electricity trading compa-ny may be, in accordance with chapter 11 The Electricy Act and the contract, entitled to discontinue the electricity transmission. Before the company terminates the electricity transmission certain conditions must be met. These conditions are part of the consumer protection on the electricity market and consequently the electricity trading company is hindered from taking unfound disconnection. This protection consists of a set of condi-tions and for the disconnection to be justified all of those conditions must be met. An ex-ample of a condition that hinders the electricity company from pursuing disconnection is if the Social Welfare Board agrees to take on the liability for the electricity debt. In reality on-ly some economically vulnerable consumers are going to be affected by the provisions re-garding disconnection of transmission of electricity. In such cases the Social Welfare Boards’ commitment to pay is crucial for the consumers’ right to continuing consuming electricity. The Social Welfare Board grants the financial assistance as a last possible resort. Therefore only some of the most financially vulnerable consumers will be able to retain electricity, while others are deprived of this right. The Electricity Trading Company’s right to disconnect the transmission of electricity is en-sured already by law which means that the contract is superfluous. The Contracts’ basic function is to ensure that the consumer pays. Therefore the consumers’ obligation to pay should in an explicit manner be legislated.

Conselho Nacional de Desenvolvimento Científico e TecnológicoCadmium (Cd) is considered one of the most toxic heavy metals for its ability to affect different tissues, including the brain and the immune system. The molecular mechanisms of toxicity of Cd are not well established, however, it is known that one of the consequences of Cd exposure is the generation of oxidative stress. Conversely, the quercetin, one flavonoid present in various foods performs various therapeutic functions in the body, such as antioxidant activity, anti-inflammatory and neuroprotective action. Thus, the aim of this study was to investigate the effects of quercetin on the behavioral tests, the activity of the enzymes acetylcholinesterase (AChE), Na+, K+-ATPase and the δ-dehydratase aminolevulinic acid (δ-ALA-D), as well as parameters of oxidative stress in the central nervous system of adult male wistar rats exposed to CdCl2. The activities of enzymes AChE, NTPDase and adenosine deaminase (ADA) of peripheral lymphocytes, butyrylcholinesterase (BuChE) in the serum and myeloperoxidase (MPO) in plasma were also measured in the peripheral system of these animals. The rats were exposed to CdCl2 (2.5 mg / kg) and quercetin (5, 25 or 50 mg / kg) by gavage (1 ml/kg) for 45 days. Hence, the animals were divided into eight groups (n = 10-14): saline/control, saline/Querc 5 mg/kg, saline/Querc 25 mg/kg, saline/Querc 50 mg/kg, Cd/ethanol, Cd/Querc 5 mg/kg, Cd/Querc 25 mg/kg and Cd/Querc 50 mg/kg. The groups treated with Cd and quercetin, received the antioxidant quercetin solution after 30 minutes of the administration of Cd solution. At the end of 45 days of the treatment the animals were submitted to training and behavioral tests. After, they were anesthetized by halothane inhalation, and blood collection was performed to set serum, plasma and peripheral lymphocytes apart. Then the animals were euthanized, with part of the brain being removed for analysis of the enzyme δ-ALA-D activity, while the other part of brain was dissected into, cerebral cortex, striatum, cerebellum, hippocampus and hypothalamus, for future enzymatic assays. The results showed that Cd is able to cross the blood brain barrier, therefore, although the amount of Cd accumulated in the different brain structures studied was low, it was significantly higher than in control. Simultaneous treatment of quercetin in Cd exposed animals was ineffective to decrease these levels of Cd. The Cd exposure caused impairment on learning and memory, besides causing an increase in the anxiogenic behavior type. Nevertheless, the treatment with quercetin prevented the undesirable effects caused by exposure to the metal in the anxiety and memory. In relation to enzymatic activities in the brain, it was observed that Cd exposure reduced AChE activity in cerebral cortex and hippocampus, while as activation of the enzyme was observed in hypothalamus. Furthermore, a decrease in the Na+, K+-ATPase enzyme activity in cerebral cortex, hippocampus and hypothalamus was observed, as well as a decrease in the δ-ALA-D activity in total brain of Cd exposed animals. Interestingly, the quercetin co-administration in the Cd exposed animals prevented the changes in the activity of the enzymes AChE and Na+, K+-ATPase in different brain structures, though has not restored the δ-ALA-D enzyme activity. It was also observed an increase in ROS production, in lipid peroxidation, in protein oxidation, the levels of double stranded DNA and changes in the antioxidant system, such as, reduction in the glutathione reductase (GR) activity, levels of total thiols (T-SH) and reduced glutathione (GSH), and an increase in the glutathione S-transferase (GST) enzyme activity in cerebral cortex, hypothalamus and hippocampus of Cd exposed animals. Co-administration of quercetin in Cd exposed rats was able to prevent totally or partially the changes caused by metal exposure in oxidative stress parameters. It is suggested that quercetin is able to reduce the oxidative damage caused by exposure to these metal and subsequently restore the AChE and Na+, K+-ATPase activities, modulating cholinergic neurotransmission and improving cognitive processes. In relation to the peripheral system, there was an increase in the NTPDase, ADA, AChE, BuChE and MPO activities in Cd exposed rats. Based on these results it is possible to infer that the increase in NTPDase activity is a compensatory effect due to the increase in ATP levels in circulation. It is suggested that decreased levels of ACh are available in the circulation due to increase in the peripheral cholinesterase activity. When rats were treated with the quercetin, flavonoid was able to modulate the activities of these enzymes probably due to the anti-inflammatory property of the compound. Accordingly, it is suggested that quercetin prevents or eases the toxicity caused by exposure to metal due to its antioxidant and anti-inflammatory activities. Therefore, it is believed that the flavonoid may be a promising drug in alternative therapies against toxicity induced by the metal in the central nervous system and peripheral system.
O cádmio (Cd) é considerado um dos metais pesados de maior toxicidade devido a sua capacidade de afetar diferentes tecidos, incluindo o encéfalo, bem como o sistema imunológico. Os mecanismos moleculares de toxicidade do Cd ainda não estão bem estabelecidos, contudo, sabe-se que uma das consequências da exposição ao Cd é a geração de estresse oxidativo. Por outro lado, a quercetina, um flavonoide presente em vários alimentos, exerce diversas funções terapêuticas no organismo, como atividade antioxidante, anti-inflamatória e ação neuroprotetora. Sendo assim, o objetivo do presente estudo foi investigar os efeitos da quercetina sobre os testes comportamentais, a atividade das enzimas acetilcolinesterase (AChE), a Na+,K+-ATPase e a δ-desidratase aminolevulinato (δ-ALA-D), bem como os parâmetros de estresse oxidativo no sistema nervoso central de ratos machos wistar adultos expostos ao CdCl2. Também foi avaliada, no sistema periférico destes animais, a atividade das enzimas AChE, NTPDases e adenosina desaminase (ADA) de linfócitos periféricos, butirilcolinesterase (BuChE) do soro e a mieloperoxidase (MPO) do plasma. Os ratos foram expostos ao CdCl2 (2,5 mg/kg) e quercetina (5, 25 ou 50 mg/kg) por gavagem (1ml/kg) durante 45 dias. Para isso, os animais foram distribuídos em oito grupos (n=10-14): salina/controle, salina/Querc 5mg/kg, salina/Querc 25 mg/kg, salina/Querc 50 mg/kg, Cd/etanol, Cd/ Querc 5mg/kg, Cd/Querc 25mg/kg e Cd/Querc 50 mg/kg. Os grupos tratados com Cd e quercetina receberam a solução antioxidante após 30 minutos da administração da solução de Cd. No final do período de 45 dias de tratamento os animais foram submetidos aos treinos e aos testes comportamentais. Posteriormente, foram anestesiados, através da inalação de halotano, e foi realizada a coleta de sangue e separação de soro, plasma e linfócitos periféricos. Em seguida os animais foram submetidos à eutanásia, com parte do encéfalo sendo retirada para a análise da atividade da enzima δ-ALA-D, enquanto que outra parte foi dissecada em córtex cerebral, estriado, cerebelo, hipocampo e hipotálamo, para posteriores ensaios enzimáticos. Os resultados obtidos mostraram que o Cd é capaz de atravessar a barreira hematoencefálica, pois, embora a quantidade de Cd acumulada nas diferentes estruturas encefálicas estudadas tenha sido baixa, ainda assim, foi significativamente maior que o controle. O tratamento concomitante da quercetina nos animais expostos ao Cd foi ineficiente em diminuir estes níveis de Cd. A exposição ao Cd causou prejuízos na aprendizagem e memória, além de causar um aumento no comportamento do tipo ansiogênico. Por outro lado, o tratamento com a quercetina preveniu os efeitos indesejáveis causados pela exposição ao metal na ansiedade e memória. Em relação às atividades enzimáticas no encéfalo, verificou-se que a exposição ao Cd reduziu a atividade da enzima AChE no córtex cerebral e no hipocampo, enquanto que uma ativação da enzima foi observada no hipotálamo. Além disso, observou-se uma diminuição na atividade da enzima Na+, K+-ATPase no córtex cerebral, hipocampo e hipotálamo, bem como uma diminuição na atividade da δ-ALA-D no encéfalo total de animais expostos ao Cd. Interessantemente, a co-administração com a quercetina em animais expostos ao Cd impediu as alterações na atividade das enzimas AChE e Na+, K+-ATPase em diferentes estruturas encefálicas, embora não tenha restaurado a a atividade da enzima δ-ALA-D. Verificou-se, também, um aumento na produção de ROS, na lipoperoxidação, na oxidação de proteínas, nos níveis de DNA dupla fita e alterações no sistema antioxidante, como a diminuição na atividade da enzima glutationa redutase (GR), nos níveis de tióis totais (T-SH) e glutationa reduzida (GSH), e um aumento na atividade da enzima glutationa S-transferase (GST) no córtex cerebral, hipocampo e hipotálamo dos animais expostos ao Cd. A co-administração da quercetina nos ratos expostos ao Cd foi capaz de impedir totalmente ou parcialmente as alterações causadas pela exposição ao metal nos parâmetros do estresse oxidativo. Sugere-se que a quercetina é capaz de diminuir o dano oxidativo causado pela exposição ao metal e, subsequentemente, restaurar a atividade da AChE e Na+, K+-ATPase, modulando, assim, a neurotransmissão colinérgica e melhorando os processos cognitivos. Em relação ao sistema periférico, verificou-se um aumento na atividade das enzimas NTPDase, ADA, AChE, BuChE e MPO nos ratos expostos ao Cd. A partir desse resultado pode-se inferir que o aumento na atividade da NTPDase seja um efeito compensatório devido ao aumento dos níveis de ATP na circulação. Sugere-se que níveis diminuídos de ACh estão disponíveis na circulação devido ao aumento na atividade das colinesterases periféricas. Quando os ratos foram tratados com quercetina o flavonoide foi capaz de modular a atividade dessas enzimas provavelmente devido à propriedade anti-inflamatória do composto. Deste modo, propõe-se que a quercetina previne ou ameniza a toxicidade causada pela exposição ao metal devido a sua atividade antioxidante e anti-inflamatória. Logo, acredita-se que este flavonoide possa ser um fármaco promissor em terapias alternativas contra a toxicidade induzida pelo metal no sistema nervoso central e periférico.

This thesis deals with notes to the financial statements and their explanatory power. Firstly annual financial statement is presented shortly with other context. Then content of the notes to the financial statements is specified in details together with information how should the notes look to provide satisfactory explanatory power. A survey of the real notes was realized for evaluation of these notes. Information stated in the notes were evaluated and the average number of errors in these notes was found out. In the survey it was found out that three errors you can find in the notes of unaudited companies on the average and that the notes of audited companies are worse than the notes of unaudited companies. The main finding is that you can find errors in the notes to the financial statements and these errors can reduce the explanatory power.

Full textAbstract:
Heroic tales recount violence, which can be defined as a deliberate assault on the body of another against their will. The act of violence is a culmination of courage, determination, contempt for rules and the power to act; violence appears as a paradigmatic test of the individual. Violence forces those involved to position themselves in relation to it – perpetrators as well as victims, participants as well as bystanders, contemporaries as well as descendants. In this volume, three perspectives on the heroization, endurance and avoidance of violence structure different literary, historical, cultural and sociological approaches to identifying the relationship between the heroic and physical violence. An introductory essay identifies theoretical intersections between violence and heroism. With contributions by Ronald G. Asch, Cornelia Brink, Ulrich Bröckling, Olmo Gölz, Joachim Grage, Felix K.

Full textAbstract:
Schools have become the default mental health providers for children and adolescents, but they are often poorly equipped to meet the mental health needs of their students. The introduction tackles how to make students eligible for school-based services using the Individuals with Disabilities Education Act or Section 504 of the Rehabilitation Act. Using the new DSM-5 as an organizing principle, this book then addresses the 12 most common mental disorders of childhood and adolescence, ages 3–18. While there are many books that address child and adolescent psychopathology, this book focuses on how to help students with mental disorders in pre-K–12 schools. Each chapter addresses the prevalence of a disorder in school-age populations, appropriate diagnostic criteria, differential diagnosis, comorbid disorders, rapid assessment instruments available, school-based interventions using multitiered systems of support, and easy-to-follow suggestions for progress monitoring. Unique to this book, each chapter has detailed suggestions for how school-based clinicians can collaborate with teachers, parents, and community providers to address the needs of youth with mental health problems so that school, home, and community work together. Each chapter ends with a list of extensive web resources and a real-life case example drawn from the clinical practice of the authors. The final chapter addresses two newly proposed diagnoses for self-harm in the DSM-5 and brings a cautious and sensible approach to assessing and helping students who may be at risk for serious self-injury or suicide.

Full textAbstract:
The Protection of Plant Varieties and Farmer’s Rights Act, 2001, promises to balance the intellectual property rights of plant breeders and farmers under one umbrella legislation. However, there remain several grey areas and the rights of farmers, in reality, are still tenuous. Though the rights framework was foregrounded on an understanding between non-governmental organizations and industry, there is lack of clarity at both conceptual and procedural levels. In this context, Sophy K. Joseph analyses the impact of legal policy reforms during the ongoing Second Green Revolution on farmers’ customary rights and livelihood. The author discusses how the extension of private property rights to plant varieties, seeds, and other agrarian resources changed the demographic composition of the rural space, with increased migration of cultivators to the cities. The book argues that the transition from state interventionism (during the First Green Revolution), to state abstention (in the Second Green Revolution) has dramatically influenced India’s conventional agrarian practices and traditions. This work maps the evolutionary process of neoliberal economic and legal policies and its interference with primary concerns such as food security, food sovereignty, and agrarian self-reliance of the country.

Full textAbstract:
AbstractPotassium (K) is found in plants as a free ion or in weak complexes. It is easily released from living or decomposing tissues, and it should be considered in fertilization programs. Several factors affect K cycling in agroecosystems, including soil and fertilizer K contributions, plant K content and exports, mineralization rates from residues, soil chemical reactions, rainfall, and time. Soil K+ ions can be leached, remain as exchangeable K, or migrate to non-exchangeable forms. Crop rotations that include vigorous, deep-rooted cover crops capable of exploring non-exchangeable K in soil are an effective strategy for recycling K and can prevent leaching below the rooting zone in light-textured soils. The amount of K released by cover crops depends on biomass production. Potassium recycled with non-harvested components of crops also varies greatly. Research with maize, soybean, and wheat has shown that 50–60% of K accumulated in vegetative tissues is released within 40–45 days. A better understanding of K cycling would greatly improve the efficacy of K management for crop production. When studying K cycling in agricultural systems, it is important to consider: (1) K addition from fertilizers and organic amendments; (2) K left in residues; (3) K partitioning differences among species; (4) soil texture; (5) soil pools that act as temporary sources or sinks for K. In this chapter, the role of cash and cover crops and organic residues on K cycling are explored to better understand how these factors could be integrated into making K fertilizer recommendations.

Full textAbstract:
Abstract Narrative is introduced as a cultural practice and life form which contributes to creating the foundation of our lives as it helps us to interpret the world, through stories, in which we must be able to act. Borrowed from Ricœur (Time and narrative: The configuration of time in fictional narrative (Vol. 2, K. McLaughlin & D. Pellauer, Trans). Chicago, IL: The University of Chicago Press (1985) and The course of recognition (D. Pellauer, Trans). Cambridge, MA: Harvard University Press (2005).), the concepts of time and space are presented as the contexts and products of narrative. The functions of storytelling are discussed under the heading of “technologies of Self-construction” (inspired by Foucault, Technologies of the self. In L. H. Martin, H. Gutman, & P. H. Hutton (Eds.), Technologies of the self: A seminar with Michel Foucault (pp. 16–49). Amherst, MA: The University of Massachusetts Press (1988).), which provide orientation, self-understanding, and transgression. These need to be developed within the constraints of social norms—so the theory goes—and yet subjects still have some room to move within the process of adopting norms (Butler, Giving an account of oneself. New York, NY: Fordham University Press (2005).).

Full textAbstract:
Topical application of vitamin K is beneficial in the treatment of various skin pathologies. However, its delivery to the skin is hampered by the photo-instability and phototoxicity of vitamin K (quinone form). Indeed, topical use of vitamin K is regulated in Europe owing to the photosensitive properties of this molecule. Here, we discuss the suitability of ester derivatives of vitamin K hydroquinone (VKH), the active form of vitamin K, for topical applications. Notably, VKH derivatives have the potential to overcome the photo-instability and phototoxicity problem of vitamin K and act as VKH prodrugs, as demonstrated in HaCaT human keratinocytes. Thus, VKH prodrug is a promising strategy for topical application of vitamin K without the need for special protection from light.

Full textAbstract:
This chapter looks at a universal bundle for a compact Lie group. By Milnor's construction, every topological group has a universal bundle. Independently of Milnor's result, the chapter constructs a universal bundle for any compact Lie group G. This construction is based on the fact that every compact Lie group can be embedded as a subgroup of some orthogonal group O(k). The chapter first constructs a universal O(k)-bundle by finding a weakly contractible space on which O(k) acts freely. The infinite Stiefel variety V (k, ∞) is such a space. As a subgroup of O(k), the compact Lie group G will also act freely on V (k, ∞), thereby producing a universal G-bundle.

In Japan Atomic Energy Agency (JAEA), the three-dimensional two-fluid model analysis code considering the supercritical pressure water based on ACE-3D (Advanced Code for Evaluation of 3-Dimensional two-phase flow) has been developed to establish the thermal-hydraulics design by numerical analytical approach for the Super Critical Water Reactor (SCWR). In this paper, in order to evaluate the prediction accuracy of ACE-3D for the heat transfer-characteristics at the pseudo critical point, a numerical analysis of the supercritical water using ACE-3D based on the three dimensional two-fluid model has been conducted for simulating the experiments in a heated tube with both upward and downward flow. For the turbulence model in this analysis, both the standard k-ε model and the low-Reynolds number type k-ε model which uses the Launder-Sharma model were examined to investigate the influence of the turbulence model on the heat transfer-characteristics near the heated wall near the pseudo critical point. As a result, it was found that the numerical results of wall temperature using the low-Reynolds number k-ε model for upward flow in a heated tube were in good agreement with experimental data compared with that of using the standard k-ε model.

Full textAbstract:
In the near term, biomass in various forms is the most available renewable energy source in the USA, particularly in the wild land-urban interface (WUI). With current high natural gas (NG) prices the possibility of gasifying biomass and developing a local Biomass Alliance with Natural Gas (BANG) so that the biomass gas (BG) can supplement natural gas (NG) could have many energy, environmental and economic (EEE) benefits. An analytic cost estimation (ACE) method is used to assess various BANG technologies potentially applicable at the WUI and to determine NG prices at which BG capable systems can deliver electricity at competitive costs. ACE is based upon the approximate linear relationship between cost of electricity (COE = Y), and cost of fuel (COF = X), i.e., Y = K + SX, as seen in many detailed cost analyses of electrical generating systems. ACE is here used to guide efforts directed towards energy sustainability in the WUI where nearby biomass stores are abundant. Thermal conversion and the use of the fuel to supplement NG is considered here at various power (P) levels to lower the cost of electricity. A reasonable K(P) and S(P) for NG fired electrical generation systems is first established. Then using an Antares Group Inc. report (AGIR) analyses of eleven biomass fueled technologies K(P) and S(P) are identified using only three adjusted parameters for each technology. An accurate analytical equation is also found for AGIR calculations of net present value (NPV = Z) vs. P and Y. These equations are then used to interpolate and extrapolate the AGIR economic analyses to other Ps and X or Y in some cases leading to other conclusions than in the AGIR. We conclude that BANG can save energy costs in many communities at the WUI and lead the way to: the development of economically competitive woody biomass supply and applications industries provide jobs, stabilize local economies, reduce USA’s dependence on imported fuels and lower greenhouse gas emissions.

This paper presents computational study for a large diameter (216 mm) and small space ratios (S/D = 0.25 and 0.5) jet impingement flow. CFD-ACE code was used as the computational tools; the code was first validated by comparing its predictions with both CFD and experimental data from the literature. Then, the study was performed for two different Reynolds numbers: 7600, 17700 and two different space ratios: 0.25 and 0.5. Also two different turbulence models were utilized in this study: low Reynolds number turbulent k-ε and k-ω. The CFD results were compared with flow visualization results conducted at the University of Minnesota for the same configurations. The impact of choosing different inlet conditions on the CFD flow field was examined. The k-ε model showed greater sensitivity to the selection of the inlet conditions. Moreover, the k-ω model showed much better agreement with the experimental data than the k-ε model.

Full textAbstract:
Steady flow over rounded and ducted tip hydrofoils has been studied computationally using the CFDRC-ACE(U) flow solver and a k-ε turbulence model. The flow domains were gridded with a combination of C-H, H-H, tetrahedral and prism grid blocks and mesh sizes ranged from 350,000–550,000 cells. A good agreement in flow pattern was achieved between the numerical solutions and available experimental data. The computations show that the ducted tip hydrofoil sheds less bound circulation over the majority of the wing span than does a rounded tip hydrofoil with the same cross section and aspect ratio. Observation of the streamwise component of vorticity immediately downstream of the different hydrofoils shows that the vorticity from the ducted tip hydrofoil is shed in the shape of a duct instead of the concentrated circular vortex shed by the rounded tip hydrofoil.

Full textAbstract:
Abstract A novel data-driven approach is used to describe a spatially varying turbulent diffusivity coefficient for the Higher Order Generalised Gradient Diffusion Hypothesis (HOGGDH) closure of the turbulent heat flux to improve upon RANS cooling predictions in film cooling flows. Machine learning algorithms are trained on two film cooling flows and tested on a case of a different density and blowing ratio. The Random Forests and Neural Network algorithms successfully reproduced the LES described coefficient and the magnitude of the turbulent heat flux vector. The Random Forests model was implemented in a steady RANS solver with a k-ω SST turbulence model and applied to four cases. All cases saw improvements in the predicted Adiabatic Cooling Effectiveness (ACE) over the cooled surface compared to the standard Gradient Diffusion Hypothesis (GDH) approach, but only minor improvements in the centreline and lateral spread are seen compared to a HOGGDH model with a constant cθ of 0.6. Further improvements to cooling predictions are highlighted by extending these data-driven approaches into turbulence modelling to improve flow field predictions.

Large Eddy Simulations and RANS predictions have been carried out for a generic primary zone type jet configuration, for which significant LDA experimental data is available. It consists of an annular passage feeding a row of ports that issue jets into a confined crossflow. A bleed flow of 50% past the ports in the feed annulus and a jet to cross flow ratio of 5 are set-up in order to be representative of annulus fed primary jets. Time averaged inlet boundary conditions have been taken from experimental data and have had time-correlated fluctuations with the correct RMS values and time scales imposed on them. Calculations have been performed on a modest PC cluster using the CFD-ACE+ flow solver package. Results show that LES is able to surpass RANS quantitatively and qualitatively. At the time-average impingement point of the jets the LES predicted normal stresses are in considerably better agreement with experimental data than is RANS, which is to be expected considering the limitations of k-ε models relying upon linear stress-strain relationships. Phenomena impossible to capture using RANS are also well predicted by LES, such as bimodal pdf’s that have been witnessed at the time average stagnation point where the cross flow and jet back flow meet. By solving for a conserved scalar it has also been possible to examine mixing rates within the recirculation zone.

An axial-swirl, lean premixed fuel injector typical of stationary gas turbine combustors has been analyzed using Large Eddy Simulation (LES). The objective of the study was to evaluate the LES modeling approach for predicting emissions of CO and NOx at practical engine conditions (P = 13.6 atm, Tin = 734 K = 861°F) and over a range of natural gas-air equivalence ratios (0.42 to 0.58). Experimental data from a recent UTRC/DOE-NETL program was used to evaluate the model. The experimental tests found NOx emissions decreased significantly with a decrease in equivalence ratio while CO emissions decreased initially, but then increased at the leanest conditions. LES calculations were performed using a parallel (domain decomposition), pressure-based, unstructured-grid flow solver within the CFD-ACE+ commercial software. The LES software solves the general transport equations for mass, momentum, energy, and chemical species without assumption at the grid- and time-resolved scales of the flow, and models the turbulent mixing and chemistry below the locally resolved grid/time-scales. The Localized Dynamic subgrid Kinetic energy Model (LDKM) was used to model the unresolved turbulence and a 2-step assumed PDF method, with decoupled NOx, was used to model the unresolved turbulence-chemistry interactions. Parallel calculations on a cluster of 22 Linux-based PCs were carried out. It was shown that LES was able to accurately predict the CO and NOx at an equivalence ratio of 0.58, and at leaner equivalence ratios the model was able to give qualitative agreement with the measurements. Some inadequacies in the NOx chemistry at ultra lean conditions and the near-wall flow boundaries were observed.

Full textAbstract:
In this paper CFD analysis of the steady two-phase turbulent combusting flow in a single annular low-NOx combustor is presented. For this purpose the commercial code CFD-ACE (1998) was used, where Eulerian equations are solved for the gas phase and the liquid spray fuel droplets are treated in a Lagrangian frame of reference allowing for evaporation of droplets and providing source terms for the gas phase. The standard k-ε model was used for turbulence and an assumed shape probability density function was used for the instantaneous chemistry in the conserved scalar combustion model. Thermal NOx is assumed to be the only source of NOx production and is decoupled from the gas phase reacting flow and calculated in a postprocessing step. The calculation is done on a block structured multi-domain computational grid. Particular attention has be paid to the detailed modeling of the fuel injector having multiple air swirler passages starting from the trailing edge of the air swirler vanes and utilizing up to 400000 computational grid cells for the entire model. The model represents the single annular low-NOx combustor for the BR700 aircraft engine family, which is based on a Rich Burn - Quick Quench - Lean Burn (RQL) concept. CFD analysis is done for high power reduced take off conditions and is compared with full annular rig test results for the temperature traverse and the integral EINOx. The results imply satisfactory prediction capability for the EINOx and the average radial temperature distribution. The prediction of the details of the temperature traverse is not satisfactory and will remain a challenge for the future.

Professor M. Zhytaryuk’s review is about a book scientific novelty – a monograph by Professor M. Tymoshyk «Ukrainian journalism in the diaspora: Great Britain. Monograph. K.: Our culture and science, 2020. 500 p. – il., Them. pok., resume English, German, Polish.». Well-known scientist and journalism critic, Professor M. S. Tymoshyk, wrote a thorough work, which, in terms of content, is a combination of a monograph, a textbook and a scientific essay. This book can be useful for both students and practicing journalists or anyone interested in the history of the Ukrainian diaspora, Ukrainian journalism and Ukrainian culture. The author dedicated his work to Stepan Yarmus from Winnipeg, Canada – archpriest, journalist, editor, professor. As the epigraph to the book were taken the words of Ivan Bagryany: «Our press, born under the sword of Damocles of repatriation», not only survived and survived to this day, but also showed a brilliant ability to grow and develop. It was shown that beggars that had come to the West without money at heart can and know how to act so organized. It was also an example of how a modern «enbolshevist» and «denationalized» by the occupier man person is capable of a combined mass action».
