The objective of this study was to evaluate the biological aspects of C. flavipesyour markup, and the development of a methodology for adult capture. Sugarcane borers fed on artificial diet containing the dyes SudanRed7B and Solvent Blue 35 in concentrations of 200 and 400 ppm, vegetable oil at 200 and 400 ppm and without oil. Later, the caterpillars were parasitized in the above treatments. We evaluated the period between parasitism and larvae emergence, pupation, weight of the masses and pupae, sex ratio, adult longevity and marking. After the setting of the dye / marker suitable concentration for adult C. flavipes, we evaluated the dispersibility and parasitism of adult females under field conditions. We used the Dunnett test for the variables related to the development of larvae, pupae and adults of C. flavipesand the GLM procedure for analysis of variance and the LSMEANS to fit the media in each factor tested. Set up The SudanRed 7B dye at a concentration of 200 ppm is the best dye / concentration to mark the larval parasitoid C. flavipes after developed the methodology for capturing C. flavipes, which associated with marking, allowed evaluating the flight capacity by distance and capture these individuals accurately. It was defined bottle trap 600 as the best pet for evaluation capture and parasitism. The maximum flight distance field in individuals was 17 meters, and the captured number was increased up to five meters.80% of the traps with captured females were parasitized.

An artificial diet was developed for laboratory rearing of the cottonwood leaf beetle, Chrysomela scripta F., and the imported willow leaf beetle, Plagiodera versicolora (Laicharting). To reduce microbial contamination of the media, procedures were developed for separating egg masses and sterilizing egg surfaces. Cottonwood leaf beetle larvae reared from neonate to adult on this artificial diet had greater mortality, took longer to develop, and were smaller than larvae reared on fresh poplar foliage. Adult longevity was similar for both diet-and foliage-reared larvae. Survival and adult fresh weight of imported willow leaf beetle larvae reared on the artificial diet were similar to those of cohorts reared on fresh poplar foliage. However, individuals reared on artificial diet took longer to develop and produced shorter-lived adults than cohorts reared on foliage. Larvae of both species would not eat fresh foliage after being fed on the artificial diet. Adults of both species maintianed on the artificial diet laid few eggs but resumed normal oviposition when fed fresh foliage. This artificial diet proved useful for rearing larvae and maintaining adults during periods when fresh foliage was limited.

The article analyzes the implementation mechanism and organizational system of anti-religious agitation and propaganda in Soviet Ukraine. The author recorded a conflict between the republican and all-union centers for religious cults regarding the implementation of religious policies and atheization of the population. It is analyzed how the change in the state leadership of the USSR in 1954 led to a radical reassessment of the ideological struggle with religion as a relic of class formations in the minds of people.It was established that in the 1960s cinematographic works were actively involved in anti-religious propaganda. The actual number of regional commissioners to the Council for Religious Affairs also increased, committees for assistance were set up in all cities and districts of the regions, public councils for the coordination of anti-religious work were organized under the regional committees of the Communist Party of Ukraine. It was found out that within the framework of the atheistic education of society, the Soviet leadership introduced the concept of Soviet «non-religious» holidays and rituals, honoring the leaders of communist labor. The structural formalization of organizations responsible for the introduction of the new Soviet rituals in the 1970s is analyzed.The article describes the employment of the media resource and state publishing houses that published millions of copies of atheistic periodicals and literature for the sake of «eradicating the religious consciousness of the masses» by the party leadership. The reduction of state influence on the affairs of believers since the mid-1960s and the harsh criticism of the liberal course in relation to religion at the All-Union Conference of Commissioners for Religious Affairs in 1972 are analyzed. It is proved that, despite the «Perestroika», the idea of religion as a reactionary ideology and the need to transform the society of mass atheism into a society of general atheism prevailed in atheistic education.The author found out that in the Central Committee of the Communist Party of Ukraine a discussion on the importance of rethinking the strategy of religious policy to establish a dialogue with churches and guaranteeing believers the possibility of religious freedom began only in 1990.

Barbaric, savage, horrific-these were terms to define the decision of the Islamic State of Iraq and Syria (ISIS) to murder its captured Jordanian pilot by burning him alive inspired a thesaurus of horror and revulsion. The men who did it, the perpetrators were described by the media as mad men, thugs, monsters. To most of the people, the act itself seemed inexplicable and without sense. However, behind the choreographed and videotaped violence lies a calculated horrible cold logic. Although, ISIS is often portrait as a mighty force on the ground in Syria and Iraq, facts state that they control mainly communications between various provinces in both countries, and, as most guerrilla armies, are militarily weak by conventional measure. ISIS has little or almost none defense against the bombing campaign that is facing now, while US has formed a coalition that is confronting them on the ground as well, after President Barack Obama published the “New Security Doctrine” which includes degrading and finally destroying ISIS. ISIS, however, have proven to be very organized in promoting dramatic acts of violence against their enemies and promoting them two achieve two goals: use terror tactics as a psychological weapon against all those facing them and all those that are to face them in combat. Secondly, through usage of social network platforms to promote killings and executions, the aim of ISIS is to encourage recruits from out of Syria and Iraq, and elsewhere, to join them in their cause. Online operations of ISIS fall under a production group called the Al Hayat Media Center. The Center was created to seduce Westerners into joining the ranks of ISIS and also to distribute propaganda through social and media platforms. It is difficult to assess the success of this operation, but solid sources provided by US military and intelligence estimate that at least 300 Americans are fighting in the ranks of ISIS (at least two Americans have been killed fighting for ISIS in Iraq/Syria region) while the number of Europeans is in thousands. The US Response to this psychological kind of warfare came when President Barack Obama established the Center for Strategic Counterterrorism Communications (CSCC) aiming to combat terrorist propaganda. The main strategy of CSCC is not directly to confront ISIS operatives, but rather than that to deal with the people they are trying to recruit. Now, with almost entire international public opinion on their side, it is time for US to more actively respond to ISIS especially in the manner of psychological warfare since it is obvious that operations of “winning hearts and minds” of people in Iraq and Syria are not enough compared to ruthless tactics of ISIS which “winning hearts and minds” by brute force, terror, and vivid violent images. The online propaganda war is a new component to conflicts of 21st century that allows enemies to reach one another’s home fronts directly. ISIS might seem not so strong on the ground but it has captured one fundamental flaw of the media of 21st century-the one that bad news is always good news and that televised violence will always have an audience. ISIS has proclaimed that its goal is to create a caliphate of 21st century but its psychological warfare and propaganda is inspiring individuals throughout the West to commit horrible terrorist crimes. Could this be another mind game set up by ISIS, it remains to be seen. However one thing is for certain, US and its allies must tackle ISIS not only by planes and other military means, but also by a strategy that would eliminate its influence in spreading their propaganda.

The objective of this work was to compare biological aspects and life table parameters of the coccinellids Harmonia axyridis, Cycloneda sanguineaand Hippodamia convergens. Insects were fed eggs of Anagasta kuehniella, and reared at 24.5±1ºC, 70±10% relative humidity, with a 12 hour photophase. Hippodamia convergenstook about 1.6 day to complete development, longer than H. axyridis, and 2.4 day longer than C. sanguinea.At immature stages, H. axyridisexhibited the highest survival percentage (49.2%), in comparison to the other coccinellids. For mean adult longevity, H. convergenswas deficient, in comparison with the other species. Mean period of pre oviposition was the longest in C. sanguinea; the longest oviposition time occurred for H. axyridis; and the post oviposition period was similar between the coccinellids. Considering the reproductive parameters, H. axyridisshowed the best performance in all aspects. For life table, the values of H. convergenswere higher than, although close, to those of H. axyridis. Nevertheless, the high net reproductive rate of H. axyridis showed this species potential to increase population size. The biological characteristics of the exotic H. axyridis favors its invasion and establishment in Brazil, corroborating results noticed in other countries.

As an important pest, Tetranychus urticae fed on thousands of host plants and showed strong capability in host adaptation. However, hardly any success artificial diet has been developed for it. In this study, we compared adult longevity and reproduction of T. urticae that fed on its natural food (bean leaves) and an artificial diet with leaf extracts added, and tried to investigate the reason why the artificial diet was inefficient through transcriptome analyses. Mean adult longevity and cumulative fecundities of T. urticae was reduced by 53.4% and 93.8%, respectively. Transcriptome analyses showed that 1731 genes were differentially expressed comparing individuals fed with the artificial diet and with their natural food, among which most (77.1%) were down regulated. No significant induced expression of xenobiotic transporters and detoxification enzymes were observed when T. urticae were fed with the artificial diet. In contrast, differentially expressed genes were mainly enriched in digestive related terms, especially in lipid metabolism related pathways, with most genes down regulated. Our results indicated the significance in further investigating lipid demand and metabolism of T. urticae to improve its mass rearing techniques.

At present, a commercially available magnetic barrel machine equipped with permanent magnets has some faults arising from constructional reason. That is, grinding or finishing ability is different from place to place in the machining region, resulting in the limitation on the region we can use in the container of workpieces. Therefore, in this research, authors made the new magnetic barrel machine equipped with three dimensional (3D) magnet arrangement to overcome these faults. The grinding ability of the new 3D magnetic barrel machine converted was experimentally examined, and compared with that of the traditional magnetic barrel machine. As a result, it was shown that we can use much broader region in the new 3D machine. It was also shown that the grinding ability became higher. The distribution of barrel media in action was recorded by means of a high speed video camera. It was clarified that the media rose up higher and were distributed more uniformly in the container by the effect of the magnet block newly set up. It was supposed that this must be the reason for the above-mentioned improvement of grinding ability.

The article covers the activities of the Association called Business Centre for Economic Development of the Commonwealth of Independent States. The author examines in detail the twenty-year history of this organisation, its creation, goals and objectives, features of the structure, participants and partners, and the formation of competence areas. The article emphasises that over the years of its existence, the Association has become an important and effective platform for interaction among business structures, industry associations, banking and financial institutions, entrepreneurs, the expert and scientific community as well as the media of the Commonwealth countries. Considering the Association’s key areas and forms of activity the author highlights the annual International Economic Forums involving business leaders of the Commonwealth member states, which contribute to the strengthening and development of multilateral economic relations in the post-Soviet space. The article examines in great detail the work of each Forum, its participants (both individuals and legal entities), the topics of discussions and speeches of individual speakers from various Commonwealth countries, which, in the author’s opinion, are of crucial importance for the activities of the Association called Business Centre for Economic Development of the Commonwealth of Independent States and the entire Commonwealth, as well as for the development of Eurasian integration. In addition, the article focuses on the final documents of the Forums: the author studies their main provisions with the set up in them goals, tasks, proposals and priorities.

Catalunya va viure l’1 d’octubre del 2017 un dels moments informatius més importants de la seva història. El Govern català va habilitar, desobeint el Tribunal Constitucional, 2.243 col∙legis electorals per preguntar als ciutadans si estaven a favor o en contra de la inde­pendència de Catalunya. El fet que els principals òrgans dels poders judicial i polític d’Espanya consideressin il∙legal aquest referèndum no va fer desistir els organitzadors. La jornada va estar mar­cada per la gent que va mobilitzar-se per votar i per l’actuació de la policia espanyola que va intervenir amb força. La recerca analitza com un viral de You­Tube, per denunciar irregularitats en la consulta, conté tots els ingredients per considerar-lo la principal fake news d’aquell dia. L’anàlisi es contextualitza amb opinions sobre la cobertura del re­ferèndum de quatre periodistes catalans entrevistats (Crónica Global, El País i Ara). També es confronten els relats de TV3 i TVE, en el Telenotícies i el Tele­diario. Mentre la televisió catalana va presentar l’1-O de manera èpica, per la resistència popular per salvaguardar uns drets que simbolitzaven les urnes enfront les càrregues policials; la televi­sió pública espanyola va emfatitzar que va ser una acció il∙legal, sense garanties democràtiques.   Votes in the Streets on October 1, 2017 in Catalonia: An Example of Covert Fake News On October 1st, 2017 (1-O), Catalonia experienced one of the most important newsworthy moments in its history. The Catalan government set up 2.243 polling stations to conduct a referendum on Catalonia’s independence, thereby disobeying Spain’s Constitutional Court. Although the main bodies of the Spa­nish judiciary and political powers con­sidered the referendum illegal, the orga­nizers persisted. The day was marked by people’s mobilizations, which consisted of defending polling stations and pro­tecting voters from police intervention. With this study, we seek to analyse how a YouTube video, which reported irregu­larities about the referendum and went viral, contains all the ingredients to be considered fake news. The analysis is contextualized with opinions about the media coverage of the referendum by four interviews with Catalan journalists (Crónica Global, El País, Ara). The ac­counts of TV3 (Televisió de Catalunya) and TVE (Televisión Española), in Tele­notícies (TV3’s news) and Telediario(TVE’s news) are also juxtaposed. While the Catalan public television (TV3) pre­sented the 1-O in an epic way, stressing the citizens’ resistance to safeguard the rights as symbolized by the ballot boxes against the Spanish police, the Spanish public television (TVE) emphasised that 1-O was an illegal referendum lacking democratic legitimacy.

As a cultural institution of national and global significance, the British Academy of Film and Television Arts (BAFTA) is notably absent from existing scholarship on the media industries. More importantly, BAFTA's role as an independent arts charity set up by the industry to support and develop new talent is often overlooked. Instead, references to BAFTA made by media and film scholars most frequently take the form of footnotes or digressions that detail particular awards or nominations. Drawing on a range of archival sources, including BAFTA's own records, we address this significant omission within existing scholarship on the British cultural and creative industries. In particular, we examine the period 1947–68, focusing on the 1958 merger of the British Film Academy with the Guild of Television Producers and Directors to form a new institution, known as the Society of Film and Television Arts (SFTA, later renamed BAFTA). This was achieved despite the well-documented tensions existing between the two industries throughout the period, which we identify and analyse within this historical context. We argue that a crucial factor driving the 1958 merger was the desire to develop quality training schemes across both industries. This, in turn, was partly enabled by an egalitarian turn in post-war British society towards the development of greater social equality and mobility. In reconstructing these events, we therefore interrogate and reassess the role played by this key national institution on the development of the creative and cultural industries, offering an expansion and revision of scholarship on media histories of post-war Britain.
