The aim of the work was to present the issue of eco-efficiency, based on the PN-EN ISO 14045:2012 standard in relation to the production of fatty acid methyl esters (FAME). The ecoefficiency analysis takes into account economic and environmental aspects in the improvement of products and processes / technologies. Eco-efficiency considers the product and technology throughout the life cycle, from the construction phase, through use to decommissioning. The impact on the natural environment is assessed on the basis of: consumption of energy, materials, dust and gas emissions, waste and sewage. Total costs include: production costs, raw material costs, costs during the use phase including maintenance, repair and operating costs, product disposal or recycling. The eco-efficiency analysis is helpful in making decisions regarding the selection of a new product or designing a new technology, and enables the selection of the variant that is the most economical and has the least possible impact on the natural environment. These issues are particularly important in the case of biofuels. The rapid growth of their production and the European Union’s policy, which aims to increase the share of energy from renewable sources, cause concerns of many experts regarding the threats related to the production of biofuels, both for the environment and food security. In particular, efforts are made to minimize the amount of waste and residues by implementing the idea of a circular economy. This approach promotes the development of new technologies that are more environmentally friendly. Due to the regulations set out in the RED and RED II Directives, there is a chance that the biofuels will have a less negative impact on the environment. This results from the obligation to certify compliance with the sustainability criteria, which is carried out by voluntary systems recognized by the European Commission, such as the KZR INiG System.

In this study, a method is presented to maintain real-time positioning at the decimetre-level accuracy during breaks in reception of the measurement corrections from multiple reference stations. The method is implemented at the rover by estimating prediction coefficients of the corrections during normal RTK positioning, and uses these coefficients to predict the corrections when reception of the corrections is temporarily lost. The paper focuses on one segment of this method, the on-the-fly prediction of orbital corrections. Frequently, only a few minutes of data representing short orbit ‘arcs’ are available to the user before losing radio transmission. Thus, it would be hard for the rover to predict the satellite positions using equations of motion. An alternative method is proposed. In this method, GPS orbital corrections are predicted as a time series and are added to the initial positions computed from the broadcast ephemeris to compute relatively accurate satellite positions. Different prediction approaches were investigated. Results show that the double exponential smoothing method and Winters' method can be successfully applied. The latter, however, has a better performance. The impact of the data length used for estimation of the prediction coefficients and the selection of seasonal lengths in Winters' method were investigated and some values were recommended. In general, the method can give orbital correction estimation accuracy of less than 5 cm after 15 minutes of prediction. This will result in a positioning accuracy better than 5 cm.

This study investigates the determinants of success of an experiential good: Broadway shows. The authors focus on the sources and types of information used in the selection of an artistic event and discuss the impact of critics’ reviews on the length of a show's run and attendance. In addition, the authors empirically determine the influence of other variables, such as previews, newspaper advertising, ticket prices, show type, talent characteristics, and timing of opening. The results indicate that New York newspaper theater critics have a significant impact on the success of Broadway shows. It is also found that the newspaper critics have a differential impact, with the critic from the New York Times yielding nearly twice as much influence as critics from the Daily News or the New York Post. Theater critics, it appears, are not only predictors but influencers as well. Among the various show types, musicals appear to fare better than other categories of shows. Previews have a significant impact on the attendance, but not on the longevity, of Broadway shows. Advertising also has a significant impact on both longevity and attendance. However, the characteristics of the key talent do not have a consistently significant influence on show success. In addition, ticket prices do not have a significant relationship with either longevity or attendance. The results indicate that there is an overwhelming impact of information sources, particularly the influence of critics’ reviews, on the success of Broadway shows. The authors discuss the implications of these results for the theater industry.

The five rotor models of traditional 850mm, 200*400,200*500,250*500,300*500 and 300*600 were imported into EDEM for dynamic simulation, indicated that the acceleration efficiency of new rotor was better than the traditional. In the new rotor, when the subject rotor radius was the constant, the greater the impact plate installation radius, the better the acceleration efficiency; when the impact plate installation radius was the constant, the greater the subject rotor radius, the better the acceleration efficiency.

Hematopoietic-cell transplantation (HCT) from HLA-mismatched unrelated donors can cure life-threatening blood disorders but its success is limited by graft-versus-host disease (GVHD). HLA-B leaders encode methionine (M) or threonine (T) at position 2 and give rise to TT, MT or MM genotypes. The dimorphic HLA-B leader informs GVHD risk in HLA-B-mismatched HCT. If the leader influences outcome in other HLA-mismatched transplant settings, the success of HCT could be improved for future patients. We determined leader genotypes for 11872 patients transplanted between 1988 and 2016 from unrelated donors with one HLA-A -B,-C,-DRB1 or -DQB1 mismatch. Multivariate regression methods were used to evaluate risks associated with patient leader genotype according to the mismatched HLA locus and with HLA-A,-B,-C,-DRB1 or -DQB1 mismatching according to patient leader genotype. The impact of the patient leader genotype on acute GVHD and mortality varied across different mismatched HLA loci. Non-relapse mortality was higher among HLA-DQB1-mismatched MM patients compared to HLA-DQB1-mismatched TT patients (hazard ratio 1.35; P = .01). Grades III-IV GVHD risk was higher among HLA-DRB1-mismatched MM or MT patients compared to HLA-DRB1-mismatched TT patients (odds ratio 2.52 and 1.51, respectively). Patients tolerated a single HLA-DQB1 mismatch better than mismatches at other loci. Outcome after HLA-mismatched transplantation depends on the HLA-B leader dimorphism and the mismatched HLA locus. The patient's leader variant provides new information on the limits of HLA mismatching. The success of HLA-mismatched unrelated transplantation might be enhanced through the judicious selection of mismatched donors for a patient's given leader genotype.

Laser irradiation is considered a new technology in agriculture; however, the success of irradiation depends on the selection of precise parameters for the light source and exposure. In this study, the impact of laser stimulation on germination and the occurrence of mycoflora in soybean seeds was assessed. The following factors were considered: (1) irradiation using blue and red coherent lights, (2) irradiation of seeds only (a), use of Bradyrhzobium japonicum vaccine only (b), and irradiation of the seeds plus the Bradyrhzobium japonicum vaccine (c). The germination index, seedling weight and seeds infected by fungus were determined. It was found that the laser treatment of seeds increased germination and seedling weight. Laser irradiation affected the abundance of species Phoma glomerata, Botrytis cinerea, Rhizopus nigricans and Gliocladium roseum. The use of blue laser (LB—514 nm) reduced the number of the non-pathogenic species, R. nigricans and G. roseum.

Objective: To assess the legibility of a large set of existing large format display fonts. Background: The enormous selection of fonts allows for creative design; however, while there has been a lot of research on print and computer font legibility, only a limited number of large format display font studies have been conducted. Method:  Sixty-four subjects from 19-87 years of age viewed 64 displays using 33 fonts shown on a computer monitor.  Viewing began at a very small size, which grew larger to simulate a driver or pedestrian approaching a sign.  Subjects attempted to read the displays at the smallest possible size.  Threshold legibility was determined for each font. Results and Conclusions: Font selection can make a very big difference in the distance at which a display can be read; however, there are many fonts that have equivalent legibility.  Case can sometimes, but not always, have a large impact on display legibility, with uppercase often performing significantly better than lowercase.  The choice of serif versus sans-serif alone does not have an important effect on display legibility.  Age impaired sign reading ability, but not until the participants were over sixty.  Finally, fonts that share a family name (e.g., Times Bold versus Times New Roman) can have dramatically different legibility distances. Application:  The results of this research can immediately and directly aid letter manufacturers, display designers, and display owners, as they now know how far away a large number of fonts can be read, and the impact of choosing one font style over another.

Abstract. The Sympson-Hetter (1985) method provides a means of controlling maximum exposure rate of items in Computerized Adaptive Testing. Through a series of simulations, control parameters are set that mark the probability of administration of an item on being selected. This method presents two main problems: it requires a long computation time for calculating the parameters and the maximum exposure rate is slightly above the fixed limit. Van der Linden (2003) presented two alternatives which appear to solve both of the problems. The impact of these methods in the measurement accuracy has not been tested yet. We show how these methods over-restrict the exposure of some highly discriminating items and, thus, the accuracy is decreased. It also shown that, when the desired maximum exposure rate is near the minimum possible value, these methods offer an empirical maximum exposure rate clearly above the goal. A new method, based on the initial estimation of the probability of administration and the probability of selection of the items with the restricted method ( Revuelta & Ponsoda, 1998 ), is presented in this paper. It can be used with the Sympson-Hetter method and with the two van der Linden's methods. This option, when used with Sympson-Hetter, speeds the convergence of the control parameters without decreasing the accuracy.

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.

The Impact

The process of globalization, which many times is considered as new world order is affecting all spheres of modern society but also the media. In this paper specifically we will see the impact of globalization because we see changing the media access to global problems in general being listed on these processes. We will see that the greatest difficulties will have small media as such because the process is moving in the direction of creating mega media which thanks to new technology are reaching to deliver news and information at the time of their occurrence through choked the small media. So it is fair to conclude that the rapid economic development and especially the technology have made the world seem "too small" to the human eyes, because for real-time we will communicate with the world with the only one Internet connection, and also all the information are take for the development of events in the four corners of the world and direct from the places when the events happen. Even Albanian space has not left out of this process because the media in the Republic of Albania and the Republic of Kosovo are adapted to the new conditions under the influence of the globalization process. This fact is proven powerful through creating new television packages, written the websites and newspapers in their possession.
