Opis:
Celem artykułu jest antropologiczna analiza wydarzeń, które miały miejsce w Polsce w 2016 i 2017 roku. Były to masowe protesty obywatelski przeciwko polityce rządu. Inaczej niż w większości opracowań socjologicznych i politologicznych, autor proponuje interpretować je w kategorii działań infrapolitycznych. W tym celu odwołuje się pojęcia ‘infrapolityka’, zaproponowanego niegdyś przez Jamesa Scotta, i przygląda się temu, czy i na ile można ją wykorzystać do interpretacji opisywanych wydarzeń.
The aim of the article is an anthropological analysis of the events that took place in Poland in 2016 and 2017. These were massive civil protests against government policy. Unlike most sociological and political science studies, the author proposes to interpret them in the category of infrapolitical actions. To thet end he refers to the concept of ‘infrapolitics’, once propouned by James Scott, and examines whether and to what extent it can be used to interpret the described events.

Opis:
The purpose of this article was to demonstrate the approach of the Supreme Administrative Court to ruling in cases of the “reverse distribution chain” and its effects for the entities operating public pharmacies that participate in the “reverse distribution chain”. The judgments of the Supreme Administrative Court in this area were analysed, taking into account the new legal standard prohibiting wholesale trade in medicinal products by a public pharmacy, regulations existing before the above legal standard was implemented, and the effects associated with the participation in the “reverse distribution chain”. The most important conclusion of the above analysis was the fact that the Pharmaceutical Law, when regulating trade in medicinal products, defines the principles of such trade and only on the basis thereof may the activity be conducted.

Opis:
In the solution structure of the ribosome-associated cold shock response protein Yfia of Escherichia coli in the free state two structural segments can be distinguished: a well structured, rigid N-terminal part displaying a βαβββα topology and a flexible C-terminal tail comprising last 20 amino-acid residues. The backbone dynamics of Yfia protein was studied by 15N nuclear magnetic relaxation at three magnetic fields and analyzed using model-free approach. The overall diffusional tumbling of the N-terminal part is strongly anisotropic with a number of short stretches showing increased mobility either on a subnanosecond time scale, or a micro- to millisecond time scale, or both. In contrast, the unstructured polypeptide chain of the C-terminal part, which cannot be regarded as a rigid structure, shows the predominance of fast local motions over slower ones, both becoming faster closer to the C-terminus.

Introduction. Diagnostic procedure in Coronavirus Disease 2019 (COVID-19) is based mainly on performing real-time-reverse transcription-polymerase chain-reaction (RT-PCR), which has been accepted as the gold standard method. In some cases, such as mutations of the SARS-CoV-2 genome, variable viral load kinetics or laboratory errors, it can be false-negative. Case report. The case is presented of a 56-year-old man with respiratory tract symptoms, with twice negative results of real-time-reverse transcription-polymerase chain-reaction of nasopharyngeal swabs and positive chest computed tomography, with typical findings for COVID-19 pneumonia. Conclusions. Patients with negative RT-PCR results, but with positive computed tomography findings characteristic for COVID-19, should be treated as well as those infected.

Opis:
The technology of wideband code division multiple access (WCDMA) has been applied to band selective interference cancellation system (ICS) repeaters. To inspect the telecommunication quality of the systems, quality engineers must check the shape of the signals at the corresponding frequency band of the repeaters. However, measuring the signal quality is a repetitive manual task which requires much inspection time and high costs. In the case of small-sized samples, such as the example of an ICS repeater system, Bayesian approaches have been employed to improve the estimation accuracy by incorporating prior information on the parameters of the model in consideration. This research proposes a virtual method of quality inspection for products using a correlation structure of measurement data, mainly in a Bayesian regression framework. The Bayesian regression model derives prior information from historical measurement data to predict measurements of other frequency bandwidths by exploiting the correlation structure of each measurement data. Empirical results show the potential for reducing inspection costs and time by predicting the values of adjoining frequency bandwidths through measured data of a frequency bandwidth in the course of quality inspections of ICS repeater systems.

Opis:
This paper considers a chain ratio-cum-dual to ratio type estimator for estimating population mean of the study variate using two auxiliary variates under double (two-phase) sampling procedure, when the information on another additional auxiliary variate is available along with the main auxiliary variate. The asymptotically optimum estimators (AOEs) in the class are identified in two different cases with their bias and variances. The optimum values of the first phase and second phase sample sizes have been obtained for the fixed cost of survey. Theoretical and empirical studies have also been done to demonstrate the efficiency of the proposed estimator with respect to strategies which utilized the information on two auxiliary variates.

Opis:
A supply chain system has been investigated in which a single manufacturer procures raw materials from a single supplier, processes them to produce finished products, and then delivers the products to a single retailer. The customer’s demand rate is assumed to be time-sensitive in nature (ramp type) that allows two-phase variation in the demand and production rate. Our adoption of ramp type demand reflects a real market demand for a newly launched product. Shortages are allowed with partial backlogging of demand (only for the retailer), i.e. the rest represent lost sales. The effects of inflation of the cost parameters and deterioration are also considered separately. We show that the total cost function is convex. Using this convexity, a simple algorithm is presented to determine the optimal order quantity and optimal cycle time for the total cost function. The results are discussed with numerical examples and particular cases of the model discussed briefly. A sensitivity analysis of the optimal solution with respect to the parameters of the system is carried out.

Opis:
The presented paper is an attempt to evaluate the application of different buffer sizing methods (within the critical chain approach) to a real-life project, in order to show that it is important to choose consciously one of the existing methods. The implementation of the different approaches to the buffer sizing procedure resulted in eight unique schedules. Once all the methods were implemented, the authors of this paper stumbled upon 2 inconveniences (slack vs. buffer, splitting up buffers). Funding solution for these handicaps caused obtaining eight more schedules. In order to evaluate all the determined solutions, the authors decided to establish a simulation study. A random dataset was generated of 2000 observations using the mean and variance calculated for the probability distribution determined by three possible durations (optimistic, expected and pessimistic) given by the project team members. To validate the performance of different methods, two penalty systems were designed. The test results indicate which specific buffer sizing technique performs best in the presented case, taking into account the attitude of the decision maker. The simulation study is the proposal of a method to be applied in each case of the critical chain method application, because it makes the use of the critical chain method more effective.

RAPDs, ISJs, ISSRs, ITS and katGs were applied to determine genetic relationships between common Sphagnum species of the section Acutifolia. Twenty populations were genotyped using ten ISJ primers, 12 pairs of katG primers, 10 ISSR and 10 RAPD primers, and a restriction analysis of ITS1 and ITS2. ISSR and katG markers revealed the greatest number of species-specific bands. An analysis of ITS1 and ITS2 regions with restriction enzymes also proved to be a highly effective tool for species identification.

Opis:
This paper is a  literature review to compare selected dimensions of manufacturing, services and R&D sectors supply chains. Each supply chain is seen as a  system which proper input should be proceed to gain appropriate output. Therefore, to study the supply chains, inputs, outputs and the processors specifications should be considered and the most common characteristics of each sectors’ input and output are investigated; additionally, due to wide range of supply chain specifications the factors are brought from the literature to the model to have a  unique structure of comparison: quality, cost, flexibility, competitiveness, resource utilization and innovation. The final result is a  comparison of the factors in manufacturing, service and R&D sourcing.Purpose – This paper is a  literature review. Due to novelty of R&D sourcing in compare with tangible manufacturing sourcing and intangible service sourcing, and lots of models and procedures from manufacturing sourcing were modified in services sourcing, we tried to compare manufacturing and services sourcing bold aspects with R&D souring to find out the possibilities of such modifications. Additionally, exploring on the similarities and differences could lighten up sourcing strategy selection processes.Design/methodology/approach – Supply chain management is initiated in manufacturing companies, and then various methods, procedures and strategies are modified, developed, and applied at service sector organizations. Therefore, R&D supply chains can be understood by comparing various factors of manufacturing (tangible) and service (intangible) supply chains to find opportunities for modification or innovation in R&D supply chains. The supply chain is a  system in which the input should pass out the processor to be converted into the appropriate output. Thus, in this study, inputs, outputs, and processors of supply chains are studied. Using the variation and range of supply chains factors as processor criteria, the most important characteristics of supply chains are studied: quality, cost, flexibility, competitiveness, resource utilization, and innovation.Findings – The result of the study is a  general comparison of R&D, manufacturing, and service supply chains in terms of these criteria: quality, cost, flexibility, competitiveness, resource utilization, and innovation that gives a  synergetic view pointsOriginality/Value – Modifying and developing sourcing strategies and procedures in manufacturing and service sourcing are possible approaches. The possibilities and opportunities in R&D sourcing were evaluated. Subsequently, there are not any other researches which compare R&D sourcing with manufacturing and services.

Opis:
These instructions give you guidelines for preparing papers for IFAC conferences. A reverse supply chain is configured by a sequence of elements forming a continuous process to treat return-products until they are properly recovered or disposed. The activities in a reverse supply chain include collection, cleaning, disassembly, test and sorting, storage, transport, and recovery operations. This paper presents a mathematical programming model with the objective of minimizing the total costs of reverse supply chain including transportation, fixed opening, operation, maintenance and remanufacturing costs of centers. The proposed model considers the design of a multi-layer, multi-product reverse supply chain that consists of returning, disassembly, processing, recycling, remanufacturing, materials and distribution centers. This integer linear programming model is solved by using Lingo 9 software and the results are reported. Finally, a sensitivity analysis of the proposed model is also presented.
