Abstract Vector-borne diseases are a worldwide threat to human health. Often, no vaccines or treatments exist. Thus, personal protection products play an essential role in limiting transmission. The World Health Organization (WHO) arm-in-cage (AIC) test is the most common method for evaluating the efficacy of topical repellents, but it remains unclear whether AIC testing conditions recreate the mosquito landing rates in the field. This study aimed to estimate the landing rate outdoors, in an area of Europe highly infested with the Asian tiger mosquito (Aedes albopictus (Skuse, 1894, Diptera: Culididae)), and to determine how to replicate this rate in the laboratory. To assess the landing rate in the field, 16 individuals were exposed to mosquitoes in a highly infested region of Italy. These field results were then compared to results obtained in the laboratory: 1) in a 30 m3 room where nine volunteers were exposed to different mosquito abundances (ranges: 15–20, 25–30, and 45–50) and 2) in a 0.064 m3 AIC test cage where 10 individuals exposed their arms to 200 mosquitoes (as per WHO requirements). The highest mosquito landing rate in the field was 26.8 landings/min. In the room test, a similar landing rate was achieved using 15–20 mosquitoes (density: 0.50–0.66 mosquitoes/m3) and an exposure time of 3 min. In the AIC test using 200 mosquitoes (density: 3,125 mosquitoes/m3), the landing rate was 229 ± 48 landings/min. This study provides useful reference values that can be employed to design new evaluation standards for topical repellents that better simulate field conditions.

On the basis of theoretical and practical research from the investigation of speed strength evaluation criteria for female athletes (athletes) Pencak silat aged 14-15 in Tuyen Quang province. We conduct research and application to build speed strength evaluation criteria for female Pencak silat athletes aged 14-15 in Tuyen Quang province to contribute to the formation of a system of strength evaluation standards. The speed for female athletes Pencak silat in Tuyen Quang province in general and Pencak silat athletes aged 14-15 in particular is consistent with the training characteristics of Tuyen Quang province. We have researched and selected 6 reliable and informative tests on research subjects and built 2 classification tables and 2 standard scoreboards to evaluate speed strength for women. (Athlete) Pencak silat aged 14-15, the youth team of Tuyen Quang province.

As global discussions of evaluation standards become more contextually nuanced, culturally responsive conceptions of ethics have not been sufficiently discussed. In academic social research, ethical clearance processes have been designed to protect vulnerable people from harm related to participation in a research project. This article expands the ambit of ethical protection thinking and proposes a relational ethics approach for evaluation practitioners. This centers an analysis of power relations among and within all the different stakeholder groups in order to establish, in a context-specific manner, which stakeholders are vulnerable and in need of protection. The approach also contextualizes the nature of “the public good,” as part of an ethical consideration of interest trade-offs during evaluations. The discussion is informed by our experiences in African contexts and speaks to the “Made in Africa” research agenda but is also relevant to other global contexts where alternatives to “developed country” ontological assumptions about the roles of researchers and participations and the nature of vulnerability are being reconsidered.

Testing Method

Amine collectors are widely used as oxidized ore collectors.Based on OECD 301B testing method, the biodegradability of amine collectors were analyzed and evaluated, and the values of IB of lauryl amine, octadecylamine, laurtrimonium chloride, lauryl trimethyl ammonium bromide, decane-propyl ether amine and dodecyl propyl ether amine were 173.4, 162.2, 164.6, 171.2, 160.8 and 149.4, respectively. The biodegradation of six test substances all exceeded 10% in 10 days, and all up to over 50% within 28 days. Considering comprehensively the two evaluation standards, the six amine collectors are all biodegradable. Evaluation of the biodegradability of amine collectors provides information that the chemical structure influences the biodegradability of amine collectors. It seems that the existence of ester group decreases the biodegradability of ether amine, and the shorter the carbon chain, the greater the biodegradation occurred.

This paper provides a detailed review of evaluation standards for the legal assessment of tying. This practice, which constitutes an abuse of a dominant position, is a significant breach of competition law. The mechanism of this type of abuse is based on taking advantage of market power in the supply of one product to create packed offerings capable of precluding competition from superior rival solutions. Tying occurs when one product, the “tying product”, is sold only with another product, the “tied product”. In the prevailing number of cases, tying serves to consolidate the company’s dominant position on the tied product market, which usually aims to share the tying product’s large customer group with the less-desired product. However, tying is not illegal per se. In many cases, it does not lead to any anti-competitive concerns, and might be beneficial for consumers. This is why each assessment of this conduct must be carefully evaluated with special attention given to the effects, in accordance with the generally applied effect-based approach, and also potential efficiencies. An analysis of the case-law and literature reveals the basic mechanisms for conducting a legal assessment of tying. However, the use of these mechanisms will not be possible without their adaptation to the ongoing changes caused by technological development. Digital markets not only generate incremental revenues, but are also the sources of new or unusual legal arrangements. It will more frequently be the case that existing provisions will not be able to address every new practice accurately without new acts. The Digital Markets Act aims to adapt the existing legal framework to contemporary market realities and to become a modern tool for enforcing competition law rules on digital markets. The European Commission is seeking to broaden its powers to intervene at the earliest possible stage, before an undertaking affects the competition on a market.
