In this study, an AgBr/Ag3PO4 (ABAP) photocatalyst has been prepared via a facile one-pot anion-exchange method. SEM, XRD, XPS and UV-Vis DRS characterization techniques are carried out to study the structural and physicochemical characteristics of the AgBr/Ag3PO4 composites. The ABAP photocatalyst exhibited outstanding photocatalytic capability for the photodegradation of rhodamine B (RhB) under visible light irradiation. The optimal ABAP-48% composite displayed the highest photocatalytic activity; a complete degradation was attained in 25 min under visible light irradiation. The excellent stability and reusability of ABAP catalysts were examined by five subsequent runs. A probable degradation mechanism of ABAP composites was carefully surveyed. Furthermore, radical trapping experiments confirmed that the ˙O2− radical was the main active species in the photodegradation reaction.

In this study, soymilk was fermented with Lactobacillus casei 16. The contents of aglycone isoflavones, saponins, total phenolic, and free amino acid in the fermented soymilk, and the protection for the HepG2 cells against 2,2'‐azobis(2‐amidinopropane) dihydrochloride (ABAP) damage and the antiproliferative effects of the fermented soymilk on the HT‐29 cells and Caco‐2 cells were studied. The results showed that the levels of total phenolic, aglycone isoflavones, and free amino acids in the L. casei 16‐fermented soymilk were enhanced. The ethanol extract and the water extract of the L. casei 16‐fermented soymilk showed protection for HepG2 cells against ABAP damage and inhibited the proliferation of the HT‐29 cells and Caco‐2 cells, which may be attributed to the enhanced level of total phenolic, aglycone isoflavones, and free amino acids in the L. casei 16‐fermented soymilk., Soymilk fermented with Lactobacillus casei 16 showed the enhanced levels of total phenolic, aglycone isoflavones, and free amino acids. L. casei 16 fermented soymilk showed protection for HepG2 cells against ABAP damage and inhibited the proliferation of human colon cancer cells, which may be attributed to the enhanced level of total phenolic, aglycone isoflavones, and free amino acids in the L. casei 16‐fermented soymilk.

Some Lactobacillus strains have been reported to have antioxidative activity. In our previous work, we screened Lactobacillus plantarum Y44 for its antioxidative activity. In this study, we further studied the antioxidative activities of L. plantarum Y44 using chemical antioxidant methods, including the 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) free radical scavenging assays, the ferric reducing antioxidant power test, and oxygen radical absorbance capacity test, and we assessed damage caused by 2,2'-azobis(2-methylpropionamidine) dihydrochloride (ABAP) in a Caco-2 cell model. The results of the chemical antioxidant assays confirmed the antioxidative activity of L. plantarum Y44, which was consistent with the protection of Caco-2 cells against ABAP injury by L. plantarum Y44. We also found that L. plantarum Y44 significantly promoted expression of Nrf2 pathway-associated proteins, downregulated expression of inflammatory-related cytokines IL-8 and tumor necrosis factor-α in ABAP-damaged Caco-2 cells, and enhanced expression of the tight junction proteins β-catenin and E-cadherin. We determined that L. plantarum Y44 exerted antioxidative effects by quenching oxygen free radicals and activating the Nrf2 signaling pathway in Caco-2 cells.

Marine red macroalgae are natural sources of sulfated polysaccharides, water-binding molecules used in the food industry as thickeners, stabilizers and gelling agents. Sulfated polysaccharides extracted from the red seaweed Gracilaria caudata also show biological activities with potential therapeutic effects against diseases associated with oxidative stress; hence, it is possible that they may be used as nutraceuticals and/or food additives. This study aimed to obtain the sulfated polysaccharides from G. caudata (SP-Gc) through enzymatic extraction and to determine their chemical structure and antioxidant potential. Inductively Coupled Plasma-Optical Emission Spectrometry showed that SP-Gc have 0.9% of sulfur atoms and a degree of sulfation of 0.14%. An average molecular mass of 116.51 kDa was determined through gel permeation chromatography. The SP-Gc structure as an agar-type galactan was determined by Fourier transform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy (13C and 1H). The in vitro antioxidant activity of SP-Gc was determined through the following tests: ferrous ion chelating ability and total antioxidant capacity. The results indicated that SP-Gc have significant antioxidant activity in a concentration-dependent manner. The in vivo antioxidant activity of SP-Gc was evaluated in an oxidative stress model induced by 2,2′-azobis(2-methylpropionamidine) dihydrochloride (ABAP) in rats pretreated with SP-Gc (3 and 10 mg/kg). Catalase (CAT) and superoxide dismutase (SOD) levels were measured and all doses increased CAT and SOD activity. These results demonstrate that SP-Gc may be used as hydrocolloids, due to their characterization as agar, and as nutraceuticals, due to their antioxidant activity.

The antioxidant potential (capacity and activity) of aqueous fullerene dispersions (AFD) of non-functionalized C60, C70, and Gd@C82 endofullerene (in micromolar concentration range) was estimated based on chemiluminescence measurements of the model of luminol and generation of organic radicals by 2,2′-azobis(2-amidinopropane) dihydrochloride (ABAP). The antioxidant capacity was estimated by the TRAP method, from the concentration of half-suppression, and from the suppression area in the initial period. All three approaches agree and show that the antioxidant capacity of AFDs increased in the order Gd@C82 &lt, C70 &lt, C60. Mathematical modeling of the long-term kinetics data was used for antioxidant activity estimation. The effect of C60 and C70 is found to be quenching of the excited product of luminol with ABAP-generated radical and not an actual antioxidant effect, quenching constants differ insignificantly. Apart from quenching with a similar constant, the AFD of Gd@C82 exhibits actual antioxidant action. The antioxidant activity in Gd@C82 is 300-fold higher than quenching constants.

Did you know that object-oriented (hereafter OO) programming was introduced to SAP as far back as the year 2000 in the form of ABAP Objects? Ergo, there are some people at work who are younger than the ABAP Objects language.

With the concepts underlying xUnit now familiar to us, this next chapter covers how ABAP Unit provides the xUnit capabilities to the ABAP language.

In my opinion, using the ABAP Development Tools in Eclipse instead of the ABAP Workbench (SE80) brings lots of efficiency and new possibilities to ABAP developers’ lives. Although I know it is not easy to switch to Eclipse if you have used SE80 for many years, I hope that after reading this chapter, you will give it a try and will be happy that you did.

El desarrollo de pruebas para comprobar la calidad es un proceso meticuloso y debe seguir unos pasos con el fin de verificar que el nivel alcanzado sea aceptable para poder obtener la garantía. Tradicionalmente, el tiempo que se emplea en estos procesos es bastante considerado, no solo por el tipo de prueba, sino además por el tiempo que se consume unirlas todas y realizar un estudio en conjunto. La aparición de un software que permita integrar este tipo de pruebas hace que su coste se disminuya. El trabajo que se expone en los siguientes apartados es desarrollado mediante SAP (Systems Applications and Products in Data Processing), el cual es un sistema, aplicaciones y productos para el procesamiento de datos. Y la herramienta con la que se ha trabajado ha sido ABAP (Advanced Business Application Programming) o programación de aplicaciones avanzada para negocios, que es el lenguaje con el que se ha desarrollado SAP. Concretamente, se ha desarrollado e implementado un módulo para los terrenos de ensayo de carga de placa. El objetivo ha sido crear una interfaz con la que el usuario pueda interactuar y rellenar una serie de campos relacionados con el ensayo de carga de placa y posteriormente procesar los datos y mostrar los resultados en pantalla, así como la de generar un informe que podrá ser entregado al cliente.

“In the cloud” is where everybody wants to be—at least in recent times—and as of 2019 (just when everyone thought ABAP was about to die as a programming language), ABAP has joined the cloud party.

This paper describes the method, which is developed by the authors to automated correction of software errors, which is based on the analysis of successful project fixes for the ABAP programming language available in open repositories. The method generates the candidates of patches based on predefined templates and ranks the results by the probability of successful application, which is determined by a probabilistic model using machine learning methods. The probabilistic model is formed by training on features, which are extracted from data from successful and unsuccessful patches of ABAP programs in open repositories. The developed method is tested on synthetic examples and real projects with errors in the ABAP language. As a result of the experiments, the method successfully generated some patches, which showed their efficiency. The results in accuracy and efficiency are comparable or superior to the results of experiments in similar works by other authors., Описан разработанный подход к автоматизированному исправлению программных ошибок на основе анализа успешных исправлений проектов для языка программирования ABAP, имеющихся в открытых репозиториях. Подход основан на генерации кандидатов на исправления (патчей) по заранее определенным шаблонам и ранжирует полученные результаты по вероятности успешного применения, определяемой на основании вероятностной модели, полученной с помощью методов машинного обучения. Вероятностная модель формируется за счет обучения на свойствах, извлекаемых из данных успешных и неуспешных патчей ABAP-программ, доступных в открытых репозиториях. Разработанный подход протестирован как на искусственных примерах, так и на реальных проектах на языке ABAP с ошибками. В результате проведенных экспериментов успешно сформирован ряд патчей, которые показали свою работоспособность. Результаты по точности и эффективности сопоставимы или превосходят результаты экспериментов в аналогичных работах других авторов. авторов авторов авторов

[ES] El presente proyecto tiene como objetivo principal adecuar las necesidades de un cliente específico, otorgando la funcionalidad necesaria para poder cumplir la misión de asociar diferentes órdenes de fabricación y unirlas a un Workset. La herramienta en la que se ha realizado el desarrollo es SAP, un ERP (Enterprise Resourcing Planning) que otorga soluciones en el ámbito de la gestión empresarial. Al término ERP también se le conoce con el nombre de sistema de planificación de recursos empresariales. Lo que este sistema es capaz de otorgar es, a grandes rasgos, integrar diversas operaciones de una empresa. El distintivo entre los ERP lo podemos encontrar en el tipo de base de datos, y en la interacción de los distintos campos de la sociedad. SAP es un ERP competente para poder permitir a las empresas organizarse dada la automatización y modelados que ofrece. Los diferentes módulos que componen SAP son producción, manejo de materiales, ventas, compras, finanzas, recursos humanos, y workflows principalmente. El lenguaje de programación utilizado es ABAP (Advanced Business Application Programming), lenguaje que fue desarrollado por la propia compañía SAP. El paradigma que tiene ABAP es orientado a objetos, estructurado, e imperativo., [EN] The main objective of this project is to adapt the needs of a specific customer, granting the necessary functionality to fulfill the mission of associating different manufacturing orders and joining them to a Workset. The tool in which the development has been carried out is SAP, an ERP (Enterprise Resourcing Planning) that provides solutions in the field of business management. The term ERP is also known as the business resource planning system. What this system is capable of granting is, broadly speaking, integrating various operations of a company. The distinction between ERPs can be found in the type of database, and in the interaction of the different fields of society. SAP is a competent ERP to allow companies to organize given the automation and modeling it offers. The different modules that make up SAP are production, material handling, sales, purchases, finances, human resources, and workflows mainly. The programming language used is ABAP (Advanced Business Application Programming), a language that was developed by SAP itself. The ABAP paradigm is object oriented, structured, and imperative.

Over the years, there has been a growing interest in ERP systems - in our SAP case. These IT systems have come up with a number of novelties in terms of unifying IT and business processes. This created the premise of essential changes in data management, sorting them across multiple categories, reporting them now much faster. In the case of this article, we have transformed the ideas from the business environment into an application meant to serve the accountants in terms of monitoring and reporting their activity to their superior level. Key performance indicators (KPIs) have been defined by the business environment according to the purpose for which they were created. This required a differentiation on skill levels, so that the results were conclusive and helped the business to manage the activity he was responsible for. We wanted to provide a complete framework for KPI management in the economic organization level by developing this application – Z-KPI tool, the results being useful to the heads of department in order to well manage their work, so that the targets assumed at the beginning of the year to be achieved. The entire application was developed in SAP system, using the latest technology - ABAP WebDynpro. The software application is now in production and the degree of use is high, because the SAP system is the core system in the company for which this case study was performed.

In this study, the antioxidant capacity of the Lactobacillus plantarum Y16 fermented soybean milk was investigated by different chemical antioxidant methods and ABAP-induced oxidative stress model in HepG2 cells. It was found that the L. plantarum Y16 fermented soybean milk had better radical scavenging ability for hydroxyl and DPPH radicals, and had better ferric ion reduction ability compared with unfermented soybean milk. The cellular antioxidant assay (CAA) analysis revealed that the CAA values of ethanol and water extracts of L. plantarum Y16 fermented soymilk were dose dependent. The further research showed that the ethanol and water extracts of L. plantarum Y16 fermented soybean milk protected the HepG2 cells against ABAP oxidative damage through activating Nrf2/Keap1 signaling pathway and up-regulating the expression of heme oxygenase-1(HO-1), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-PX). The results showed that the antioxidant capacity of L. plantarum Y16 fermented soybean milk was superior to that of unfermented soybean milk.

An important topic that remains to be discussed is testing the methods and code that we write. SAP provides the unit test framework embedded in ABAP. In this chapter, we learn in detail about the following topics

After the basic introduction to ABAP provided in Chapters 1 and 2, this chapter dives deeper into the topic. It starts by showing how inheritance applies to ABAP Objects. Then, the chapter covers the concept of casting—upcasting and downcasting—and how we can achieve polymorphism using casting.

In recent releases, SAP allows you to develop ABAP programs and classes using the popular Eclipse IDE. Eclipse provides a number of useful features. We can work with a number of systems using Eclipse. Eclipse also provides a number of useful templates that can be modified according to our needs. It also includes code completion features in order to work faster. In this chapter, we look at all these features in detail.

The paper discusses the reasons of complexity rise in ERP system SAP R/3. It proposes a method for measuring complexity of SAP. Based on this method, the computer program in ABAP for measuring complexity of particular SAP implementation is proposed as a tool for keeping ERP complexity under control. The main principle of the measurement method is counting the number of items or relations in the system. The proposed computer program is based on counting of records in organization tables in SAP.

The phenolic contents, antioxidant, and antiproliferative activities of Malus doumeri were evaluated. Heyuanxiaoguo variety contained higher level of total phenolics (101.9 mg GAE/g fruit, DW), whereas Xinyishanzha variety exhibited the highest total flavonoids (85.35 mg CE/g fruit, DW), and highest cellular antioxidant and antiproliferative activities. Higher ORAC and PSC values were found in Limushan variety. Chlorogenic acid, phloretin-2′-xyloglucoside and ursolic acid were the predominant phenolics in M. doumeri , their contents were highest in Limushan (1850 mg/100g fruit, DW), Xinyishanzha (2212 mg/100g fruit, DW), and Heyuanxiaoguo variety (506.3 mg/100g fruit, DW), respectively. Among the 14 compounds identified, chlorogenic acid and phloretin glycosides accounted for 55.95% of the extracellular antioxidant capacity, while quercetin, luteolin, ursolic acid, and chlorogenic acid contributed significantly to the intracellular antioxidant activity. Furthermore, the intracellular antioxidant property of the Xinyishanzha extracts was related to the protection of endogenous antioxidant enzymes activities and inhibition of reactive oxygen species production.

An integrated microfluidic chip with arrayed micro channels consisted of eight repeat arrayed 6×6 cell culture chamber was designed and fabricated. The analytical microsystem combined with designed microchip, measuring device and environmental control unit was established for the cell culture and parallel cellular antioxidant activity (CAA) analysis of plant antioxidants. The microfluidic chip included a PDMS cover and a glass substrate which consisted of two hundreds and eighty-eight round cell culture micro chambers and forty-eight independent parallel array channels. Eight groups of different samples with six different concentrations could be investigated simultaneously with multimode reader in one test. HepG2 cells were successfully cultured on the microchip. Moreover, the viability percentage of the HepG2 cells exposed to these plant antioxidants solutions at different concentrations for 24 h was higher than 90%. With 2′,7′-Dichlorofluorescin diacetate (DCFH-DA) as a fluorescence probe, 2,2′-azobis(2-amidinopropane) dihydrochloride (ABAP) as the initiator of intracellular reactive oxygen species (ROS), we tested the inhibitory effect of several plant antioxidants such as quercetin, rutin and kaempferol on free radicals. The CAA units were calculated by the data measured from cellular morphology and fluorescence intensity over time. It was shown that the CAA units of quercetin, rutin and kaempferol were (71.42 ± 0.19) μM, (74.31 ± 0.36) μM and (69.92 ± 0.09) μM ( x ± s, n = 3), while the calculated IC 50 were (7.20 ± 0.06) μM, (52.06 ± 0.14) μM and 32.55±0.03 μM ( x ± s, n = 3), respectively.
