Abstract. The “Ponte delle Grazie” is a three spans bridge, with a total length of 72 meters, built between 1948 and 1952 in Faenza, Italy. The reinforced concrete main beams of the deck have undergone a strong deterioration over the years. In detail atmospheric agents and chemical aggressions caused a strong deterioration of the concrete, up to the point of making the structure not accessible and at risk of collapse. In fact, the five main beams were heavily damaged, as well as the concrete bearings were strongly compromised. So, an urgent intervention was necessary to save the structure of this historic bridge. A delicate restoration has allowed to remove the deteriorated concrete and to restore the resistant sections with new materials compatible with the old remaining structures. In particular, a specific rehabilitation procedure was studied using fiber-reinforced cement mortar with low elastic modulus, that is shrinkage compensated, in combination with composite materials reinforcements. Without modifying the structural behavior of the bridge, the deteriorated concrete was restored and reinforced, in a sustainable way, in order to make the structure safe and usable again. After the restoration and reinforcement the bridge capacity satisfy a reduced live load useful for urban traffic. After the restoration and reinforcement the bridge capacity satisfy a reduced live load useful for urban traffic. Even if the structure has returned to be suitable for vehicular traffic, it has been necessary to set up a real-time monitoring system, which monitors the live load and the behavior of the bridge. In detail it is used a system of geophones, that are able to detect the displacement of structures by integrating in time their response. They can provide continuous health monitoring of the bridge by transmitting the data to a remote server.
NETWORK THROUGH CENTURIES: FROM THE BYZANTINE ERA TO PRESENT DAYS
Authors: Fioretto E.
Published: May 2019

Abstract. Over the centuries, the Roman Empire enlarge and restrict its borders, as a consequence of many factors, like different emperor’s policies, wars and conquests.In a general view, we can identify them and we can consider the Danubian Limes as one of the most important one.This Limes was mostly characterized by the fact that it was corresponded with the path of the Danube river, from Germany till the Black Sea.Those lands, through centuries, were always threaten by the risk of barbarians’ incursions and this is the reason why the Danubian Limes had always been considered as a fragile border.During the sixth century, in the midst Byzantine Era, Justinian the I was the first emperor able to consider the problem of the military protection not even “site by site”. He felt the need of an (absolutely modern) idea of considering the limes as a network of sites, who need each other to guarantee a strong and efficient result.Speaking about the architectonical choices, the system of military camps and fortress starts to change its identity, becoming cities with specific relations.Focusing on the case study of Serbia, the aim of the work is to map the specific location of each archaeological site, trying to use this network as an index of places. The research would like to highlight the important value of those sites as Cultural Heritage, considering the necessity of their preservation and valorization as historical evidence in a new European and common scenario.
SPECIFITY OF HISTORICAL BUILDINGS AND BIM METHODOLOGIES. A FIRST EXPERIMENTATION FOR THE FEDERICO II HEADQUARTERS IN NAPLES
Authors: Picone R. , Veronese L.
Published: May 2019

Abstract. The Building Information Modeling is today one of the most advanced data cataloging and processing systems aimed to the digital representation of physical and functional characteristics of an object. These prerogatives make possible to create a model containing not only the geometric-architectural data of the building, but also the properties of the materials and technical elements that compose it, the construction phases, as well as maintenance operations, locating and programming them over time. Such an approach implies, therefore, not only a change of instruments for the representation of Architecture, but above all a change of "mentality", in which the building is seen as a "unitary" organism with a synchronous vision between architectural form, structural elements, construction techniques, materials and installations. The experimentation here presented concerns the case of the university complex of Federico II of Naples along the axis of Via Mezzocannone. The urban palimpsest housing the monumental front of the building, designed by Eng. Pierpaolo Quaglia and Guglielmo Melisurgo at the end of the Nineteenth century, and incorporating ancient religious complexes built in the Fifteenth century, as the monasteries of Donnaromita and the Old Jesus; heterogeneous elements that allowed to explore on the field limits and the possibilities of interoperability of BIM in which still have ample possibilities for experimentation.
Circumlocution in King Abdullah II’s Discussion Papers
Authors: El-Sharif Ahmad , Owais Aya
Published: May 2019

This article studies circumlocution in King Abdullah II's Discussion Papers in light of Critical Discourse Analysis and Corpus-based analysis. The analysis aims to investigate the role of using this strategy in identifying the ideologies embedded in the discourse of democracy and reform adopted by the Jordanian Monarch. The study relied on a small corpus of the seven Royal Discussion Papers published between December 2012 and April 2017. The study demonstrated that King Abdullah II considerably employs circumlocution in his Discussion Papers to convey his vision, ideas, and ideologies about democracy and reform in Jordan by repeating a set of keywords to accentuate his vision of the enactment of reform and democracy in Jordan. These keywords are found to reflect the King’s ideologies on the basis of four key assumptions: the Partakers, Reform, My Nation, and Optimism and Sanguinity.
Haitian/Vilokan Idealism, Lakouism, and the Vodou Ethic and the Spirit of Communism
Authors: Mocombe Paul C.
Published: May 2019

The demystification of the Vodou religion or ontology as practiced in Haiti, epistemologically reveals a form of transcendental idealism and realism, Haitian/Vilokan Idealism, which produces a hermeneutical phenomenology, materialism, and an antidialectical process to history enframed by a reciprocal justice as its normative ethics.  This work posits and concludes, that Haitian ontology, Vodou/Vilokan, gave rise to its epistemology, Haitian/Vilokan Idealism, which subsequently gave rise to the Vodou Ethic and the spirit of communism and the lakou system as its form of social and system integration, respectively.
O PROCESSO DE ENVELHECIMENTO E A ATRIBUIÇÃO DE SENTIDO À VIDA
Authors: Andrade-Boccato Taiane Do Nascimento , Franco Adriana De Fátima
Published: May 2019

Este artigo tem como objetivo analisar o processo de atribuição de sentido à vida por idosos. O envelhecimento populacional já é uma realidade nos países mais desenvolvidos e tem provocado mudanças significativas a níveis econômico e social; segundo dados demográficos, no Brasil o mesmo fenômeno está ocorrendo. Com o aumento da população idosa emerge a necessidade de compreender o que é envelhecimento, não por uma perspectiva puramente biológica, sobretudo, a partir da vivência dos próprios idosos. Realizou-se uma pesquisa de campo por meio de entrevistas com duas idosas. As análises de seus relatos foram realizadas a partir das contribuições teóricas da Psicologia Histórico-Cultural sobre desenvolvimento humano.  Compreendeu-se que o sentido da vida na velhice é constituído pelas atividades, ou seja, por meio de suas vivencias.  E, ainda, à medida em que o idoso se apropria dos conhecimentos há a possibilidade de transformação dos significados e sentidos. Sendo assim, para além de um fenômeno cronológico, a velhice aparece como uma síntese da vida vivida e um momento de possibilidades.
A resposta de observação e os estudos sobre a discriminação nas décadas de 1930 e 1940
Authors: Endemann Peter
Published: May 2019

A investigação empírica sobre o processo da discriminação realizada nas décadas de 1930 e 1940 foi acompanhada por um longo debate, conhecido com a Controvérsia Continuidade vs. Descontinuidade. Questões sobre a natureza seletiva da discriminação e o papel de respostas sensoriais compuseram o problema de pesquisa de Wyckoff que culminaria na elaboração do conceito e do delineamento experimental da resposta de observação. Com o objetivo de apresentar o contexto histórico de surgimento da resposta de observação, a presente pesquisa foi conduzida com base nas referências dos artigos originais de Wyckoff. O delineamento de observação permitiu a obtenção de medidas independentes de duas classes de respostas importantes para o estabelecimento da discriminação. O papel das respostas sensoriais e, especificamente, da resposta de observação foram abordados experimentalmente a partir de condições onde o contato do organismo com os estímulos discriminativos não é garantido ou favorecido pelo arranjo de estímulo.

Published: May 2019

Tomato is one of the most popular vegetables, with high nutrient demand. The nutrient concentration can vary depending on the development phase, cultivation system, temperature, soil conditions, luminosity, relative humidity and management practices. The aim of this work was to characterize cherry tomato visual symptoms of deficiency, as well as the effect of nutritional restriction on the development and nutrient concentration of plants cultivated in nutrient solution. Plants of the cherry tomato, cultivar Sindy, were grown in green house. We have used eleven treatments, one control with complete nutrient solution and the other ten omitting respectively the nutrients nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, zinc and iron. The experiment was performed in randomized design with three repetitions. After 60 days, the plants were removed from the solutions and their main symptoms were photographed and described. The traits evaluated were: total dry matter yield, dry matter of leaves, dry matter of stems and dry matter of roots; number of leaves, number of inflorescences; number of fruits and root volume. The concentration and accumulation of nutrients: nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, zinc and iron in leaves, stems and roots were evaluated. Nutrient concentration and accumulation were influenced by the deficiencies imposed. The visual symptoms of deficiency that had appeared firstly were those of phosphorus, boron and iron, respectively. The omissions of the nutrients nitrogen, magnesium and boron were the ones that most compromised the dry matter production of the cherry tomato plants.

This study was undertaken to examine the herbage accumulation dynamics and structural characteristics of digit grass subjected to different defoliation frequencies in the period of January 2015 to February 2016. Four defoliation frequencies [very high (25 cm), high (35 cm), medium (45 cm), and low (55 cm)] were evaluated in two periods of the year [greater insolation (September to March) and lesser insolation (April to August)]. The experiment was set up as a randomized-block design with four replicates. Overall, the decreasing defoliation frequencies increased the cutting interval; leaf area index; total-herbage, stem, and dead-herbage accumulation rates; and percentages of stems and dead herbage. This reduction in defoliation frequency also resulted in a lower leaf accumulation rate and percentage of leaves. In overall terms, digit grass showed higher total-herbage, leaf, and stem accumulation rates; percentages of stems and dead herbage; stem volume density; and tiller density in the period of greater insolation. In the period of lesser insolation, however, digit grass exhibited a lower dead-herbage accumulation rate and a lower percentage of dead herbage. Less frequent defoliations increase the herbage accumulation rates of digit grass, but result in a less desirable morphological composition.

It is undeniable which soil management systems with intensive use of machines and with little formation of organic matter result in the deterioration of the soil structure. The relation among the values of organic matter in the soil profile as function of the quantity of residue left on the soil surface during the harvest has been little documented. This evaluation will be very important to provide and to apply the best optimization model of the soil management system. The objective of this work was to value the contribution of the mulch cover of maize and oat straw, applied in the soil surface at different quantities and of the soil textural porosity at the change of the soil structural porosity. The experiment was carried out from August to November 2005 on a Oxisol, with clay texture, located at the Experiment Farm of Agricultural Engineering from the UNIOESTE, Cascavel, Paraná, Brazil (24°54′ S; 53°31′ W). The average soil texture in top 20 cm was 126, 195 and 679 g kg-1 of sand, silt and clay respectively. Aggregates sizes distribution, soil bulk density, particles density and textural density and soil organic matter were determined at the laboratory for evaluation of the soil structural parameters. For all conditions: application rates, and distribution in the layers of soil depth, the cover with oat straw produced more organic matter and presented a positive effect faster on the soil structural voids ratio than the coverage with maize straw.
TRABALHO DECENTE SEGUNDO A OIT: UMA CONCEPÇÃO DEMOCRÁTICA? ANÁLISE CRÍTICA À LUZ DA TEORIA DO CONTRATO SOCIAL

Published: May 2019

A partir da teoria do Contrato Social de Jean-Jacques Rousseau e da percepção de Boaventura de Sousa Santos acerca da hodierna crise desse Contrato, o artigo discute a natureza democrática da adoção pela OIT da concepção de Trabalho Decente, pondo em causa o tripartismo e o diálogo social aplicados tanto na escala internacional, quando da eleição do Trabalho Decente como diretriz das ações da OIT, quanto na escala estatal, por ocasião da elaboração da Agenda Nacional do Trabalho Decente brasileira. Conclui-se que as concepções de Trabalho Decente e da Agenda Nacional de Trabalho Decente brasileira, a despeito de não serem antidemocráticas, também não podem ser tomadas como suficientemente democráticas, ante a crise do Contrato Social, que afeta, de forma direta, os pilares da democracia representativa e da função socialmente inclusiva do trabalho, com a consequente fragilização da representatividade das entidades sindicais e do papel Estado enquanto agente normalizador das desigualdes sociais. Empregaram-se o método de abordagem hipotético-dedutivo e os métodos de procedimento histórico e bibliográfico.

Published: May 2019

Background. In cardiac surgery, patients face an increased risk of developing postoperative delirium (POD) that is associated with poor outcomes. Neuron-specific enolase (NSE) and glial fibrillary acidic protein (GFAP) have shown some promising results as potential tools for POD risk stratification, diagnosis, monitoring, and prognosis. Methods. Prospective single-centre study enrolled 44 patients undergoing elective coronary artery bypass grafting (CABG) and/ or valve procedures using cardiopulmonary bypass (CPB). The patients were assessed and monitored preoperatively, during surgery, and in the early postoperative period. The blood levels of NSE and GFAP were measured before and after surgery. The early POD was assessed by CAM-ICU criteria and patients were assigned to the POD group (with POD) or to the NPOD group (without POD) retrospectively. Results. The incidence of POD was 18.2%. After surgery, NSE significantly increased in the whole sample (p = 0.002). Comparing between groups, NSE significantly increased in the POD group after surgery (p = 0.042). ΔGFAP (before/after operation) for the whole sample was statistically significant (p = 0.022). There was a significant correlation between ΔGFAP and the lowest MAP during surgery in the POD group (p = 0.033). Conclusions. Our study demonstrated that NSE and GFAP are associated with early POD. An increase in NSE level during the perioperative period may be associated with subclinical neuronal damage. Serum GFAP levels show the damage of glial cells. Further studies are needed to find the factors influencing the individual limits of optimal MAP during surgery.
Prophylactic anti-coagulation after severe burn injury in critical care settings
Authors: Blake Megan , Roadley-Battin Ruth , Torlinski Tomasz
Published: May 2019

Background. Severely burnt patients are at an increased risk of thromboembolic complications, hence sufficient prophylactic anticoagulation is of paramount importance. Local guidelines at the Burns Centre in the Queen Elizabeth Hospital, Birmingham therefore advise increasing the standard dose of low molecular weight heparin in these patients. An audit was carried out to assess the current practice in burns patients to ensure adequate anticoagulation and adherence to guidelines. Materials and methods. Retrospective data was collected on all burns patients in the Burns Centre over a two-year period. The main objectives were to assess: • anticoagulation regimes prescribed to severe burns patients • monitoring of Anti-Factor Xa levels • adjustment of dosing based on the results The locally produced trust guidelines were used as the comparator. Results. All burns patients were prescribed anticoagulation, but often the dose was not increased as suggested in the guidelines. Although most of the severely burnt patients were prescribed adjusted higher doses of anti-coagulation, only 60% of these patients were monitored with Anti-Factor Xa assays. Of these assays, 66% showed sub-prophylactic levels. The majority of results led to the adjustment of the dose of anticoagulant. However, often dose changes were made late. Discussion and conclusions. The audit confirmed the need for increased doses of prophylactic anticoagulation in severe burns. The better adherence to the guidelines can be achieved by additional training and implementation of decision support via electronic prescribing system.
Metformin poisoning treated with high dose insulin dextrose therapy: a case series
Authors: Young Theodore , Cevallos Joaquim , Napier James , Martin-Lazaro Juan
Published: May 2019

Purpose. We describe the compassionate use of high dose insulin dextrose (HID) for life threatening metformin associated lactic acidosis (MALA) in four patients admitted to intensive care. Methods. Patients presenting with refractory lactic acidosis believed to be secondary to metformin poisoning were included. High dose insulin dextrose at 0.5units/kg/hour was infused in 50% dextrose. Frequent blood gas analysis allowed titration of therapy. All patients also received continuous veno-venous haemofiltration. Results. All four patients recovered to normal or near normal lactate and pH between 10 and 24 hours of therapy. Two patients had significant separation in time between initiation of HID and haemofiltration to suggest an independent effect of HID on improving pH and lactate. All patients had at least one episode of hypoglycaemia below 4.0 mmol/L with the lowest glucose in any patient during therapy being 3.0 mmol/L. All episodes were corrected with a dextrose infusion without sequelae. Conclusions. Our study demonstrates that HID therapy appears to be safe in patients with suspected metformin poisoning. It also appears to work to drive down lactate, improve pH and patients’ clinical condition. Further evidence is required to assess the effectiveness of HID therapy in the context of MALA.
The correlation of post-operative acute kidney injury and perioperative anaemia in patients undergoing cardiac surgery with cardiopulmonary bypass

Published: May 2019

Background and objective. Acute kidney injury (AKI) following cardiac surgery with cardiopulmonary bypass (CPB) is polyethiological clinical syndrome. During CPB haemodilution develops, which is useful in reducing the risk of thrombosis; however, haemodilutional anaemia decreases oxygen transfer and provokes tissue hypoxia, which can lead to acute organ damage. The aim of the study was to find out the impact of perioperative anaemia on AKI after cardiac surgery with CPB. Materials and methods. This prospective study included 58 adult patients undergoing elective cardiac surgery with CPB, without any preoperative chronic renal disease or any systemic autoimmune disease. Serum concentrations of NGAL had been tested before the surgery, 2 hours, 6 hours, and one day after the surgery. Perioperative anaemia was assessed according to the Ht value before the surgery, the Ht value during CPB, and immediately after the surgery. Results. The rate of haemodilutional anaemia is 77.59% in this study. The average of serum NGAL concentration before CPB was 63.95 ± 33.25 ng/mL and it was significantly lower than the average concentration 2 hours after the surgery, 6 hours after the surgery and one day after the surgery (respectively 148.51 ± 62.39, 119.44 ± 55, 128.70 ± 59.04 ng/mL, p < 0.05). AKI developed in 46.55% of the patients. A significant positive reasonable correlation between the development of perioperative anaemia and AKI was determined (r = 0.50, p < 0.05). Conclusions. Post-operative AKI after cardiac surgery with CPB has a moderate positive correlation with perioperative haemodilutional anaemia. A longer CPB time and aortic cross-clamping time were found to be the risk factors for the development of AKI.
ECCO2R as a bridge to a decision in type II respiratory failure
Authors: Grauslytė Lina , De La Cerda Gonzalo , Jovaiša Tomas
Published: May 2019

Introduction. End-of-life decisions are often time consuming and difficult for everyone involved. In some of these cases extracorporeal life support systems could potentially be used not only as a bridge to treatment but as a tool to buy time to allow patient’s participation in decision making and to avoid further futile invasive procedures. Case report. A previously healthy 53-year-old female patient presented with respiratory failure of unknown cause. In the course of treatment her condition was deemed irreversible and the only option for any chance of long-term survival was a lung transplant. During this whole time the patient’s condition was managed with extracorporeal carbon dioxide removal system (ECCO2R). She remained compos mentis and expressed the wish to stop all the treatment as the option of lung transplant was not acceptable to her. Treatment was withdrawn and she passed away. Discussion. In cases of end-of-life decisions, time can play an essential role. Even though extracorporeal life support systems have been conceptualised to be a bridge to treatment, they could be beneficial in a situation when time is needed to make a decision. ECCO2R has been used as a treatment method in different settings, however, in this case it served as a tool to maintain the patient alive and conscious for a sufficient time for her to participate in decision making. Conclusions. Our case report demonstrated that ECCO2R could serve as a bridge to decision in situations when time is limited and the decisions that need to be made are difficult.

A zoo animal's neighbourhood: how conspecific neighbours impact welfare
Authors: Whitham JC , Miller LJ
Published: May 2019

While the zoological community strives to provide the best possible living environment for non-human animals, space limitations constrain where zoos can house particular species. Therefore, an individual may live in proximity to animals that impact its behaviour, physiology, reproductive function or overall welfare status. This article examines how solitary and social species living in managed settings are positively and negatively affected by conspecific neighbours. When making housing decisions, zoos should follow husbandry recommendations outlined by zoo associations, integrate natural history information and attempt to view the environment from the perspective of the species of interest. Furthermore, researchers can collect survey, behavioural and physiological data to examine how variables, such as density, distance between neighbours, the age/sex of conspecifics and types/amount of exposure to others influence welfare. Ultimately, zoos should consider the needs of individuals and investigate whether welfare can be enhanced by modifying enclosures, husbandry routines, enrichment schedules or access to conspecifics. A zoo's willingness to alter an animal's exposure to conspecifics may have a substantial impact on physical, mental and emotional health.

Differences across cyclophilin A orthologs contribute to the host range restriction of hepatitis C virus
Authors: Gaska Jenna M , Balev Metodi , Ding Qiang , Heller Brigitte , Ploss Alexander
Published: May 2019

The restricted host tropism of hepatitis C virus (HCV) remains incompletely understood, especially post-entry, and has hindered developing an immunocompetent, small animal model. HCV replication in non-permissive species may be limited by incompatibilities between the viral replication machinery and orthologs of essential host factors, like cyclophilin A (CypA). We thus compared the ability of CypA from mouse, tree shrew, and seven non-human primate species to support HCV replication, finding that murine CypA only partially rescued viral replication in Huh7.5-shRNA CypA cells. We determined the specific amino acid differences responsible and generated mutants able to fully rescue replication. We expressed these mutants in engineered murine hepatoma cells and although we observed increases in HCV replication following infection, they remained far lower than those in highly permissive human hepatoma cells, and minimal infectious particle release was observed. Together, these data suggest additional co-factors remain unidentified. Future work to determine such factors will be critical for developing an immunocompetent mouse model supporting HCV replication.
Aspect extraction on user textual reviews using multi-channel convolutional neural network
Authors: Da’u Aminu , Salim Naomie
Published: May 2019

Aspect extraction is a subtask of sentiment analysis that deals with identifying opinion targets in an opinionated text. Existing approaches to aspect extraction typically rely on using handcrafted features, linear and integrated network architectures. Although these methods can achieve good performances, they are time-consuming and often very complicated. In real-life systems, a simple model with competitive results is generally more effective and preferable over complicated models. In this paper, we present a multichannel convolutional neural network for aspect extraction. The model consists of a deep convolutional neural network with two input channels: a word embedding channel which aims to encode semantic information of the words and a part of speech (POS) tag embedding channel to facilitate the sequential tagging process. To get the vector representation of words, we initialized the word embedding channel and the POS channel using pretrained word2vec and one-hot-vector of POS tags, respectively. Both the word embedding and the POS embedding vectors were fed into the convolutional layer and concatenated to a one-dimensional vector, which is finally pooled and processed using a Softmax function for sequence labeling. We finally conducted a series of experiments using four different datasets. The results indicated better performance compared to the baseline models.

Aim: This study was carried out to determine the occurrence of extended-spectrum beta-lactamase (ESBL) producing bacteria in salad vegetables in Ondo City, Nigeria.

Study Design: An experimental study design with randomized sampling.

Place and Duration of the Study: The research was carried out in the Department of Biological Sciences of Wesley University, Ondo State, Nigeria.

Methodology: Samples of cucumber, carrot, green pea, green beans, sweet corn and cabbage were analysed on appropriate agar medium. Pure isolates were identified by biochemical tests and confirmation was done by the use of API 20 E and API 20 NE in accordance with standard procedures. ESBLs screening was carried out using the double disk synergy test. Data were statistically analyzed using MedCalc statistical software (version 17.2).

Results: Total viable bacterial counts (TVBCs) ranged from 1.1 × 103 to 7.1 x 105 cfu/ml; total coliform counts (TCC) ranged from 1.2 x 102 to 3.9 x 103 cfu/ml while total faecal counts (TFC) ranged from 0 to 2.9 × 102 cfu/ml. There were statistical differences in mean TVBCs of the samples (P < 0.05).  The mean TCCs of cabbage, carrot and cucumber showed no statistical significance; green beans, green pea and sweet corn also showed no statistical significance (P > 0.05). One hundred and sixty (166) isolates obtained from the samples were identified as Bacillus cereus, Citrobacter freundii, Escherichia coli, Klebsiella pneumoniae, Morganella morganii, Pseudomonas aeruginosa, Proteus mirabilis, Staphylococcus aureus, Serratia marcesens and Staphylococcus saprophyticus. At least one member of all bacterial species, except S. saprophyticus, produced ESBL. 

Conclusion: This study revealed that salad vegetables could be a vehicle for the spread of extended-spectrum beta-lactamase-producing bacteria which translates to a threat to public health around the world as salads are loved and consumed by all categories of people globally.

Intra-seasonal drought episodes during the life cycle of plant growth of sesame affect physiological quality of seeds harvested. For this purpose, in this study, we explored the following water treatments: W1 (Irrigation throughout the cycle, non-stress treatment), W2 (water stress at the vegetative growth phase), W3 (water stress at the flowering to early pod formation), W4 (water stress at the fruit maturation phase) and W5 (water stress in all phases); for their effect on germination capacity and seedling from the produced seeds of four sesame varieties (“SN 203”, “SN 403”, “SN 01-06” and “Ngong”). Such studies allowed evaluating the performance of the seeds harvested from the plants subjected to water stress availability during the different phenological phases of each variety. The produced seeds were evaluated by reduction rate (%) of germination percentage, first germination count, germination speed index, mean germination time, coefficient of velocity of germination, seedling emergence, seedling length, seedling fresh weight and seedling dry weight. In general, sesame seeds from plants grown under water deficit display reduction in performance. In water stress at the fruit maturation phase (W4) and water stress in all phases (W5), the sesame varieties tested are more sensitive for both germination capacity and seedling and for seedling respectively; so that water limitation during these periods results in the production of seeds with reduction in performance more intense. Among the varieties tested, “SN 01-06” and “Ngong” were the most tolerant genotypes. These results will be used for extension of sesame and for genetic improvement program.

The present study evaluate the effects of vinasse and filter cake on the efficacy of indaziflam, saflufenacil, and sulfentrazone for the control of morning glory (Ipomoea triloba L.) and crabgrass (Digitaria horizontalis Wiild), as well as the effects of these byproducts on the emergence of these weeds. The experiments were established in a greenhouse with a completely randomized design and four replications at the Agricultural Science Center, Sao Paulo, Brazil, between May 2017 and May 2018. In the first assay, four herbicide doses: indaziflam (0, 37.5, 75, and 150 g ai ha-1), saflufenacil (0, 42, 84, and 168 g a.i ha-1), and sulfentrazone (0, 300, 600, and 1200 g ai ha-1) were applied for pre-emergent weeds in three soil covers (without byproduct, with vinasse, and with filter cake).In the second assay, seven treatments were evaluated, comparing the effects of the different vinasse and filter cake doses, and absence of byproduct on the weeds emergence. When the doses required for 80% effective control were considered, the results showed that for indaziflam, the filter cake negatively affected crabgrass control. In contrast, vinasse had a positive effect on morning glory control by saflufenacil. For sulfentrazone, the filter cake had a negative effect, requiring twice the dose used on the treatment without byproduct for effective morning glory control. Relative to assay 2, the vinasse addition affected the emergence of morning glory but not of crabgrass; however, the filter cake increased the weed biomass accumulation. Vinasse and filter cake byproducts can negatively or positively affect the performance of pre-emergence herbicides, according to the active ingredient used. However, these effects occur at doses below those recommended for the herbicides. Byproducts can affect the emergence and the weed biomass accumulation.

Dennettia tripetala fruit is a popular Nigerian fruit from the family of plant known as Annonaceae. The whole fruit (flesh and seed) is usually consumed as snacks and it is oftentimes consumed with local gin (ufofop in Ibibio or kaikai in Igbo) or added to dishes as spice due to its peculiar strong pepperish taste and sweet aroma. The present study is aimed at evaluating the antioxidant potentials of ethanol extract of ripe and unripe D. tripetala (DT) fruit in vitro. The antioxidant activity of the ethanol extract of DT was evaluated spectrophotometrically using various in vitro models like 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) and hydrogen peroxide scavenging activity; metal chelating activity and reducing power. Vitamin C was used as the standard antioxidant.Unripe and ripe DT fruits, as well as vitamin C showed a competitive inhibition of DPPH and H2O2 free radicals. As concentration of the extracts increased from 20 to100 µg/mL, the % scavenging activity for vitamin C increased from 87.86 ± 0.11 to 90.66 ± 0.07 and for ripe DT fruits from 15.15 ± 0.24 to 25.52 ± 0.23, while for unripe, fruits values increased from 12.09 ± 0.35 to 23.06 ± 0.12. The IC50 values was highest in unripe (549.23) followed by ripe (276.63) and lowest in vitamin C (12.92) indicating that vitamin C was the best scavenger of DPPH radical. Similar trend was obtained for H2O2 scavenging activity as well as reducing power. Unripe DT fruit extract was more potent at chelating metal ions (IC50 was 95.38), followed by the standard ascorbic acid with IC50 of 97.03 and was lowest in ripe DT fruit extract with IC50 value of 124.66. Unripe and ripe DT are potent antioxidants in nature and may be used to supplement our diets as rich sources of natural antioxidants for health protection.

Achieving the unidirectional transportation of bubbles in the liquid phase is of great importance for solving both academic and industrial issues. Here, Janus (hydrophobic and superhydrophobic surfaces) microhole‐arrayed polydimethylsiloxane fabricated by one‐step femtosecond laser drilling for ultrafast underwater bubble unidirectional transportation is reported. In aqueous solution, bubbles selectively penetrate from an aerophilic side to a superaerophilic one in the direction of both buoyancy and antibuoyancy, but are blocked in a reverse direction. More importantly, the bubbles readily penetrate through this Janus system within 81 ms, which is two orders of magnitude shorter than that of a previous Janus one because the aerophilic surface of current Janus system is more favorable for capturing and transporting the bubble than the superaerophobic surface of Janus system. Additionally, this “diode” presents a switchable property, which is dependent on the laser exposure dosage. According to X‐ray photoelectron spectroscopy spectrum, the underlying mechanism is that the excessive laser exposure dosage is inclined to induce the graft of oxyhydryl group as the substitution of the original hydrocarbyl group. This work may provide an innovatory insight for designing advanced materials for ultrafast gas bubble directional transportation/collection in aqueous media, in addition to gas/liquid separation.

Die Transferhydrierung von NHC‐stabilisierten Diborenen mit Dimethylamminboran verläuft mit hoher Selektivität zu trans‐1,2‐Dihydrodiboranen. DFT‐Rechnungen, unterstützt durch Kinetik‐ und Deuterierungsexperimente, lassen auf einen schrittweisen Reaktionsmechanismus schließen, bei dem zuerst das Proton und anschließend das Hydrid über ein μ‐Hydrodiboronium‐Dimethylaminoborat‐Ionenpaar als Zwischenstufe übertragen werden.

Latente Nukleophile sind Moleküle oder Verbindungen, die selbst nicht nukleophil sind, aber unter geeigneten Bedingungen eine stark nukleophile Spezies generieren. Derartige Verbindungen können die Anwendbarkeit von Lewis‐Base‐katalysierten Reaktionen drastisch erweitern. Wir berichten nun, dass N‐silylierte Pyrrole, Indole und Carbazole als ebensolche Nukleophile unter Einwirkung einer Lewis‐Base mit allylischen Fluoriden reagieren können. Die Reaktionen zeigen eine hohe Toleranz gegenüber funktionellen Gruppen und unter Anwendung von Cinchona‐Alkaloiden als Katalysator lassen sich die Produkte in enantiomerangereicherter Form herstellen.
