Authors: Hoyer Carolin , Stein Patrick , Alonso Angelika , Platten Michael , Szabo Kristina 
Published: July 2019

Abstract
Background: Uncompleted emergency department care and against-medical-advice discharge represent relevant medical problems with impact on patient safety and potential medicolegal and socioeconomic consequences. They may also indicate structural or procedural problems in the emergency department (ED) relating to patient management and flow. While patients with neurological complaints frequently leave the ED against medical advice or without being seen, no dedicated analysis of this group of patients aiming at the identification of characteristics associated with irregular ED discharge has been performed so far.
Methods: A chart review was performed of all patients with neurological complaints presenting to a German interdisciplinary emergency department between January and December 2017 for neurological evaluation. Demographics, mode of presentation, process times, presenting symptoms and diagnosis were recorded. Patients leaving against medical advice after an informed consent discussion and signing of documentation (DAMA) or leaving prematurely without notifying ED staff (PL) were compared to the total of patients who were admitted or discharged (non-DAMA/PL).
Results: Of all patients presenting with neurological symptoms or complaints, 3% left against medical advice and 2.2% left prematurely. DAMA/PL patients were younger (p<.001), and they were more frequently self-presenting (p<0.001). Headaches, seizures and sensory deficits were the most frequent presenting symptoms in DAMA/PL patients, and 56.1% of those presenting with a seizure had a history of epilepsy. The most common documented reason for leaving was the duration of door-to-doctor time.
Conclusions: Younger age, self-presenting mode of presentation and presentation with headache, seizures or sensory deficits are associated with premature leave or against-medical advice discharge of patients with neurological complaints from the ED, and long waiting times were given as the major reason for leaving the ED. Increasing ED staff’s awareness of these factors and the optimization of pre-hospital assessment and demand management, thereby positively impacting on patient flow and ED process times, may help to prevent irregular discharges from the ED.
Predicting wastewater treatment plant performance during aeration demand shifting with a dual-layer reaction settling model

Published: July 2019

Abstract
Demand response (DR) programmes encourage energy end users to adjust their consumption according to energy availability and price. Municipal wastewater treatment plants are suitable candidates for the application of such programmes. Demand shedding through aeration control, subject to maintaining the plant operational limits, could have a large impact on the plant DR potential. Decreasing the aeration intensity may promote the settling of the particulate components present in the reactor mixed liquor. The scope of this study is thus to develop a mathematical model to describe this phenomenon. For this purpose, Benchmark Simulation Model No.1 was extended by implementing a dual-layer settling model in one of the aerated tanks and combining it with biochemical reaction kinetic equations. The performance of this extended model was assessed in both steady-state and dynamic conditions, switching the aeration system off for 1 hour during each day of simulation. This model will have applications in the identification of potential benefits and issues related to DR events, as well as in the simulation of the plant operation where aerated tank settling is implemented.

Published: July 2019

Background:Thiophene, thiazole, and isoxazole derivatives are present in a wide range of natural and synthetic compounds with heterogeneous pharmacological activity. Due to their structural diversity, they are some of the most versatile classes of compounds for anticancer drug design and discovery.Objective:Thiophene, thiazole, and isoxazole derivatives were herein designed with a dual purpose: as antiproliferative agents and kinase inhibitors.Methods:The test compounds were synthesized in moderate to high yields through a simple methodology. Tetrahydrobenzo[b]thiophen-5-one derivatives 5a-f were prepared from the reaction of 2-arylidencyclohexan- 1,3-dione 3a-c with elemental sulfur and either of malononitrile (4a) or ethyl cyanoacetate (4b) in 1,4-dioxan in the presence of triethylamine. Compounds 5a,b were used for the synthesis of thiophene, thiazole, and isoxazole derivatives through their reactions with different chemical reagents.Results:Antiproliferative evaluations, c-Met kinase, and Pim-1 kinase inhibitions were performed where some compounds revealed high activities. In all cases, antiproliferative activity and the kinase inhibitions were performed against six cancer cell lines and five tyrosine kinases, respectively. Where the most cytotoxic compounds were 3c, 5d, and 16c with IC50’s 0.29, 0.68, and 0.42μM, respectively, against the A549 cell line.Conclusion:The anti-proliferative activities of the newly synthesized compounds were evaluated against the six cancer cell lines (A549, HT-29, MKN-45, U87MG, SMMC-7721, and H460). The most potent compounds toward the cancer cell lines (3a, 3c, 5d, 7c, 11c, 16a, and 16c) were further investigated towards the five tyrosine kinases (c-kit, FIT-3, VEGFR-2, EGFR, and PDGFR). Compounds 3c, 5d, and 16c were selected for testing of their inhibition for the Pim-1 kinase due to their anti-proliferation activities against the cancer cell lines and their high activities against the tyrosine kinases.

O presente artigo tem como objetivo estabelecer um diálogo em torno do conceito de natureza veiculado nas histórias em quadrinhos (HQs) do personagem Chico Bento e suas relações com as concepções presentes no campo de saber da Educação Ambiental (EA). Com a intenção de problematizar a forma como as HQs, através do discurso de natureza, vêm contribuindo para pensarmos sobre EA, selecionaram-se histórias do Chico Bento publicadas entre os anos de 2009 e 2013 que fazem referência a natureza. A partir de autores como Michel Foucault, Isabel Carvalho, Leandro Guimarães, Mônica Meyer, Keith Thomas, Raymond Williams, entre outros, foram analisadas as enunciações de natureza presentes neste corpus de análise. Assim, este artigo problematiza um enunciado, que constitui o discurso de natureza e EA por meio das histórias em quadrinhos: a natureza constituída nos deslocamentos operados pelas diferenças culturais entre realidades: a rural e a urbana.

Disclosure Theory suggest that voluntary disclosure reduces information asymetry among investors by reducing transactions and information cost, which in turn reduces firms' cost of capital. The advantages of voluntary disclosure should encourage the listed firms to present voluntary disclosure besides mandatory disclosure. In fact, many listed firms reluctant to present. Voluntary dimension of corporate disclosure involve the manisfestation of free choice of the firms and its managers. Because of that, the purpose of this study is to reveal factors affecting voluntary disclosure levels for Indonesian firms listed in Jakarta Stock Exchange in 2005 and 2006.

Abstract
The aim of the study was to investigate the impact of the implementation of new health traits into the breeding objective and selection criteria for Czech Holstein cows on the genetic selection response in the breeding objective traits. Incidence of overall claw diseases was included into the current breeding objective for cows (11 traits together). Three traits that indicated claw health (incidence of claw diseases overall and infectious and non-infectious claw diseases) and incidence of clinical mastitis were successively added to the current selection criteria in a cow selection index (a maximum of 19 traits). Selection responses in the breeding objective traits were estimated by applying the general principles of the selection index theory. The required genetic variances for the new traits, the economic weights for all breeding objective traits and the genetic correlations among the selection index traits were estimated within this study. The marginal economic weights, which were calculated for two-year-old cows by applying a bioeconomic model with implemented gene flow, were -193 and -168 € per case for clinical mastitis and overall claw disease incidence, respectively. Using the comprehensive selection index with 19 traits, the reduction in the incidence of both udder and claw diseases was calculated to be 0.004 cases per cow per year. At the same time, a more favourable genetic selection response was obtained for other functional traits, e.g., +0.020% for cow conception rate and +0.010 years for productive life of cow (which represented the profit of 67 € and 367 € per herd and per year, respectively) when compared to the current index. Based on this study, a direct selection of cows for claw and udder health is nowadays recommended to improve the health status of herds and economics in production systems.

Published: July 2019

Summary
The use of insects as “novel” and natural feed materials seems to be an attractive alternative protein source for poultry, pigs and fish since more than 80% of their chemical composition (dry weight basis) is crude protein and crude fat content. Therefore, the aim of this study was to determine some chemical composition parameters of powdered mealworm larvae, as a potential animal feed as well as human novel food. It was found that the crude protein (55.83%) and crude fat (25.19%) content was predominant, as well as that the content of nitrogen-free extract was low. Coincided with the high protein content, the levels of the most important amino acids were found to be considerable, especially lysine (3.18%) and threonine (1.34%). Crude fibre content was 7.15%, while ash was 4.84%. The samples were found to be rich in most nutritive elements, especially phosphorus (1.06%) and potassium (1.12%) in terms of macroelements, and zinc (138.2 mg/kg) in terms of microelements. Based on our research and other experimental results, it can be concluded that meals from the insects originating from the order Coleoptera, Tenebrionidae (mealworms) may be successfully used as feed material in diets of livestock animals, especially poultry.
Diverse responses of old, modern and landraces of Syrian wheat genotypes to common root rot under field conditions
Authors: Arabi M.I.E. , Al-Shehadah E. , Jawhar M. 
Published: July 2019

Abstract
The yield response of widely grown cultivars and landraces of Syrian wheat challenged with common root rot (CRR: Cochliobolus sativus) was measured by comparing plots with and without artificial inoculation under experimental conditions in two consecutive seasons. The results showed that response to CRR differed depending on the susceptibility levels of the wheat cultivars, and that the disease significantly (P<0.05) reduced grain yield, number of tillers and kernel weight. The diseased plants had fewer tillers which consequently reduced grain yield per plant. Yield losses of Triticum durum cultivars were higher than those of Triticum aestivum. In addition, the T. durum landrace Horani exhibited the best level of resistance to the disease, which indicates that this landrace might be a candidate donor for resistance in future breeding programmes. As CRR can dramatically reduce wheat grain yields under favorable conditions, management practices that reduce disease severity are highly recommended.

Published: July 2019

Summary
During a survey on the biodiversity of plant-parasitic nematodes in citrus orchards of Khuzestan province (Southwestern Iran), 97 root and soil samples were collected. Nematodes were extracted and identified using morphological and morphometric diagnostic characters. Six nematode species were identified, namely: Helicotylenchus abunaamai, H. crenacauda, Pratylenchus allius, P. musii, Psilenchus hilarulus and Tylenchulus semipenetrans. Except T. semipenetrans, the remaining five species were found only in the rhizosphere of citrus, not in citrus roots, and their pathogenicity on citrus plants was not further studied. This is the first record of P. allius and P. musii for the nematode fauna in Iran. H. crenacauda is a new record for the nematode fauna in the Khuzestan province and is reported for the first time in citrus orchards in Iran. To our knowledge, this is the first report of H. abunaamai in citrus orchards worldwide.
