Streamlined Workflow Analysis Using Swim Lanes

ABSTRACT This is a case study on the workflow analysis process utilized by the technical services departments at the University at Albany SUNY in preparation for a migration from a legacy library system to a library services platform. The focus is not on specific technical services functionality but rather on the efficient, bottom-up methodology. Tasks were identified, sequenced, and entered into a spreadsheet. Responsible persons or units were marked in the appropriate cell to complete the swim lane diagram. The resulting documentation served as a simplified process diagram for the workflow that can be easily maintained on an ongoing basis.

Features of the organic-mineral intumescent paints structure formation for wooden constructions fire protection

The paper presents the results describing the features of the organic-mineral paints structure formation of the intumescent type for wooden structures fire protection. On the research basis a diagram of the coke formation process has been developed. It is shown that the introduction of titanium oxide and aluminum hydroxide in an amount of 5% promotes the ordering of the foam layer structure, an increase in its thermal stability and the achievement of the highest value of the swelling coefficient – up to 47, which is 1.7 times higher than the values of the swelling coefficient of the base composition. It was found that at 700 °C the formation of refractory compounds of the type TiP2O7, Mg3(PO4)2, AlPO4 occurs, which prevent the burnout of the formed coke foam and increase its strength and heat resistance. On the basis of the main provisions of fuzzy mathematics and data from physicochemical studies, a model of the mechanism of structure and coke formation and control of this process is proposed.

The effects of orally administered lactoferrin in the prevention and management of viral infections: A systematic review.

SummaryIt has been demonstrated that lactoferrin (LF) plays a role in host defence, but evidence on its potential antiviral property from clinical studies is fragmented. Our systematic review aimed at identifying the effects of orally administered LF against virus infections. The systematic search was conducted on PubMed, Scopus, Web of Science, BioRxiv.org and ClinicalTrials.gov from database inception to 7th January 2021. Eligible articles investigated any virus family and provided data on the effects of orally administered LF of any origin in the prevention and/or management of confirmed viral infections in people of any age. A narrative synthesis of the results was performed. Quality was assessed with the Cochrane Risk‐Of‐Bias and ROBINS‐1 tools. A total of 27 records were included, nine of which were registered protocols. We found data on Flaviviridae (n = 10), Retroviridae (n = 3), Coronaviridae (n = 2), Reoviridae (n = 2) and Caliciviridae (n = 1). Most published trials were at high risk of bias. The findings were heterogeneous across and within viral families regarding virological, immunological and biological response, with no clear conclusion. Some weak but positive results were reported about decrease of symptom severity and duration, or reduction in viral loads. Despite high tolerability, the effects of LF as oral supplement are still inconsistent, both in preventing and managing viral infections. Small sample sizes, variety in recruitment and treatment protocols, and low study quality may have contributed to such heterogeneity. Better‐designed studies are needed to further investigate its potential benefits against viral infections, including SARS‐CoV‐2.

Electrochemical aptasensor based on Mo2C/Mo2N and gold nanoparticles for determination of chlorpyrifos.

Two-dimensional Mo2C/Mo2N composites were synthesized by high temperature ball milling and used as support materials for fabricating achlorpyrifos (CPF) aptasensor. Gold nanoparticles (Au NPs) were electrodeposited on the surface of aMo2C/Mo2N-modified electrode to connect with the ferrocene (Fc) probe via Au-S bonds. The Fc probe can hybridize with the aptamer probe to form a double-stranded structure. The addition of CPF made the double strands melt and the Fc probe approached the surface of the electrode, thereby resulting in amplification of the electrochemical response. The current response of the aptasensor for detecting CPF in solutions linearly varied from 0 to 400ngmL-1 (with a maximum at 0.98V vs. Ag/AgCl). The Au NPs/Mo2C/Mo2N composites exhibited satisfactory electrochemical behavior due to their excellent electrical conductivity and large surface area. This ultrasensitive aptasensor showed a low limit of detection of 0.036ngmL-1. It was applied to determine CPF in real samples with acceptable recoveries from 94.7 to 116.7%, and the relative standard deviation was from 2.57 to 7.08%.Graphical abstract Schematic diagram of the manufacturing process of the aptasensor. Electrochemical aptasensor based on Mo2C/Mo2N/Au NP composites show excellent performance in detecting CPF.

Influence of diagram layout and scrolling on understandability of BPMN processes: an eye tracking experiment with BPMN diagrams

Business process modeling is an important activity for developing software systems—especially within digitization projects and when realizing digital business models. Specifying requirements and building executable workflows is often done by using BPMN 2.0 process models. Although there are several style guides available for BPMN, e.g., by Silver and Richard (BPMN method and style, vol 2, Cody-Cassidy Press, Aptos, 2009), there has not been much empirical research done into the consequences of the diagram layout. In particular, layouts that require scrolling have not been investigated yet. The aim of this research is to establish layout guidelines for business process modeling that help business process modelers to create more understandable business process diagrams. For establishing benefits and penalties of different layouts, a controlled eye tracking experiment was conducted, in which data of 21 professional software developers was used. Our results show that horizontal layouts are less demanding and that as many diagram elements as possible should be put on the initially visible screen area because such diagram elements are viewed more often and longer. Additionally, diagram elements related to the reader’s task are read more often than those not relevant to the task. BPMN modelers should favor a horizontal layout and use a more complex snake or multi-line layout whenever the diagrams are too large to fit on one page in order to support BPMN model comprehension.

EXAMINATION THE TRANSFERRING PROCESS OF MAIN IDEA TO SPACE DESIGN

The study, which examines the position of the main idea in interior design and the development process of the main idea, aims to emphasize the importance of the main idea in terms of the space design. The main idea is an important design decision that can be defined as the core of the design, guides the designer at every stage of the design process. There are some data that need to be analyzed at the beginning of the design process. Various notions are reached based on these data, which are called as main idea components within the scope of the study. With the determination of the notions, the main idea is developed as a solution proposal to the design problem. Subsequently, the main idea is transferred to the design by adopting design approaches focusing on different aspects. The process diagram of transferring the main idea to the design is prepared with the data obtained in the theoretical parts of the study, which main idea components, design approaches and the development process of the main idea are examined. The validity of this diagram was questioned in a field study conducted with the students of Çukurova University, Department of Interior Architecture. The design processes in the analyzed applications were evaluated in accordance with this diagram, and in the light of the findings, the study was concluded with suggestions for future studies on the subject.

Reverse supply chain conceptual model for construction and demolition waste.

Construction and demolition waste (CDW) substantially contributes to environmental degradation because of its intrinsic characteristics of fast and high generation volume, low recycling rate, and low revenue margins. A systemic problem is that recycling facilities are not usually a part of a reverse supply chain (RSC) specific for CDW. This makes the recovery process costs prohibitive, especially where companies are unable to receive and process large volumes of waste continuously. This paper presents a systematic analysis of the extant literature and utilizes the results accrued to develop a conceptual RSC model for CDW. In so doing, the research seeks to provide clarity on this phenomenon, while simultaneously stimulating wider academic discourse and further research endeavours. A mixed philosophies epistemological design was adopted using both interpretavism and constructivism to undertake a qualitative systematic analysis of the literature. A process diagram was produced to represent the conceptual model (CM) and thematically group the nodes into three key swim lanes that delineate the boundaries between distribution, manufacturing, and sourcing and warehousing processes. Within each swim lane, stakeholders were incorporated as key actors. A further layer of nuanced complexity was added to illustrate the key actors involved in the process, government strategies, and activity flow paths. This novel CM offers both practical and theoretical contributions to existing knowledge and signposts a future research direction. Such work will demystify reverse logistics for managing CDW, and assist government policy-makers to develop informed policies that reduce the negative environmental impact of construction activities.

Clinical management of an outbreak of nutritionally variant streptococcus endophthalmitis following intravitreal bevacizumab injection

BackgroundThe management of an outbreak of endophthalmitis associated with intravitreal bevacizumab represents a challenging real-time process involving identification of cases, treatment and mitigation measures during the outbreak. We summarize the clinical presentation and management of a cluster of endophthalmitis cases from contaminated bevacizumab, in addition to mathematical probabilistic assessment of the number of cases that define an outbreak.MethodsA retrospective study was conducted to assess the management of an endophthalmitis outbreak after intravitreal bevacizumab (IVB) administration. Demographic data, clinical information, individual patient management and public health reporting measures were reviewed. Outcomes of patients who received prophylactic antibiotics for endophthalmitis prevention were also reviewed. Binomial tail probability calculations were performed to determine the likelihood of clusters of endophthalmitis that could inform when an outbreak was evolving that would warrant more public health notification measures and communication.ResultsForty-five eyes of 42 patients who received IVB from a single batch were reviewed. Four cases of endophthalmitis from Granulicatella adiacens, a nutritionally-variant Streptococcus species, were treated successfully with intravitreal antibiotics ± vitrectomy. Thirty-four of the remaining 41 eyes were treated with prophylactic intravitreal vancomycin with no additional cases of endophthalmitis. Outbreak management also included CDC, ASRS and public health authority notification. Binominal tail probabilities demonstrated the rarity of clusters from a single batch (i.e. ~ 1/10,000 for 2 cases; 1/2 million for 3 cases). However, given the U.S. scale of IVB administration, there is an 87% chance of a cluster ≧ 2 and a 1% chance of a cluster ≧ 3 cases annually, which may guide outbreak management. A process diagram was developed to incorporate patient management and public health measures when an outbreak is suspected.ConclusionIntravitreal antibiotics and vitrectomy were effective in the individual management of cases of endophthalmitis, and no serious adverse events occurred with prophylactic intravitreal vancomycin for at-risk eyes. Best practices for outbreaks should be evaluated, given their likelihood within the U.S. and the sight-threatening consequences of endophthalmitis.

The article is devoted to the study of the oil industry in Russia. In particular, the monitoring of the system for ensuring the industrial and environmental safety of oil enterprises is being studied in order to reduce the risks of accidents and unforeseen situations. Audit was selected as one of the monitoring tools. The audit process was considered at example of diesel hydrotreating unit of L-24-7 fuel located on the territory of the PJSC Bashneft Bashneft - UNPZ refinery. Based on the analysis, a block diagram of the audit process was compiled and an approximate form of the audit report at the diesel hydrotreatment plant was presented. Based on the results of the study conducted on system monitoring for compliance with the requirements of industrial safety, labor protection and the environment, it was concluded that it is necessary to conduct an audit of this plant in a timely and regular manner. This, in turn, will increase the likelihood of identifying weaknesses and corresponding risks in the early stages of the development of the problem.

Development of sorting system for plastic bottle waste management

This work studies the method of sorting plastic bottles-waste. Currently, the recycling treatment for a different type of plastic bottle wastes is similar although they are made of different plastic material. The disadvantage of the current method is that the produced plastic is an unknown type of plastics. To perform recycling treatment of similar types of plastic bottle waste, the plastic-bottle waste needs to be sorted based on their material characteristics. We propose a sorting method of the plastic-bottle waste by using a barcode scanner. A database on plastic-bottle waste based on their barcode number, which then categorized their material characteristics, is first created. In this paper, the diagram of the sorting process is given.

Research of interaction process of shanks of concave disc springs of tillage machines

The article presents the results of theoretical and experimental studies of new solution of the applied research task that consists in mathematical modelling of the interaction process of concave disk spring shanks and a soil medium, taking into account the random nature of soil response, in the form of a non-linear dynamic movement model. It has allowed for determining the optimal dynamic characteristics and the design parameters of the spring shanks of a disk operating element: rigidity, reduced mass, frequency and amplitude of oscillations. A structural diagram of the interaction process of a concave disk and the soil, where oscillations of an operating element on a spring shank with a certain amplitude and frequency create a feedback in the system “soil – disk – spring shank”, has been suggested. A mathematical model has been developed and a theoretical investigation on the change in the drag forces of a disk operating element on a spring shank has been conducted. The dynamic characteristics of a spring shank in the course of unit operation have been determined within the range of the rigidity variation limits from 20 kN/m to 40 kN/m, the reduced mass limits from 100 N to 300 N, the draft force variation limits from 200 N дo 2000 N.
