Evaluation of Different Internal Designs of Hydraulic Nozzles under an Accelerated Wear Test

The use of worn-out agricultural nozzles in pesticide application has a negative effect on the efficiency and cost of the application process. It also has an effect on environmental pollution due to an excessive amount of pesticide being applied when spraying with worn-out nozzles. In this paper, the resistance to wear of three different internal design hydraulic nozzles was ascertained. Changes in the flow rate and spray distribution as a result of this wear were also investigated. The wear test was done inside a closed system, and it was accelerated using an abrasive material to generate 100 h of wear. The tested nozzles were the Turbo TeeJet (TT)-twin chambered, Turbo Twinjet (TTj60)-dual outlet, and Drift Guard (DG)-pre-orifice. Wear rate, flow rate, and the virtual coefficient of variation (CVv) were measured at different wear intervals. The results showed that the TTj60 type was the most resistant to wear, followed by the TT type and DG. The latter two types showed an increase in the flow rate only in the first 45 h of wear. Virtual coefficient of variation (CVv) values were less than 10% after finishing the test (after 100 h of wear) for the three types of nozzles, which are acceptable values according to International Organization for Standardization (ISO) 16122-2, 2015.

When the Messenger is More Important than the Message: An Experimental Study of Evidence Use in Francophone Africa

Background: Epistemic injustices are increasingly decried in global health. This study aims to investigate whether the source of knowledge influences the perception of that knowledge and the willingness to use it in francophone African health policy-making context. Methods: The study followed a randomized experimental design in which participants were randomly assigned to one of seven policy briefs that were designed with the same scientific content but with different organizations presented as authors. Each organization was representative of financial, scientific, or moral authority. For each type of authority, two organizations were proposed: one North American or European, and the other African. Results: The initial models show that there was no significative association between the type of authority and the location of the authoring organization and the two outcomes (perceived quality and reported instrumental use). Stratified analyses highlighted that policy briefs signed by the North American/European donor organization were perceived to be of lower quality than policy briefs signed by the African donor organization. For both perceived quality and reported instrumental use, these analyses found that policy briefs signed by the North American/European university were associated with higher scores than policy briefs signed by the African university whereas policy briefs signed by the North American/European regional office or international organization were associated with lower score than those signed by the African regional office of the international organization. Conclusion: The results confirm the significant influence of sources on perceived global health knowledge and the intersectionality of sources of influence. This analysis allows us to learn more about organizations in global health leadership, and to reflect on the implications for knowledge translation practices.

The Republic of Kazakhstan: Initiator Of The Organization Of Turkic States

The Cooperation Council of Turkic Speaking States (Turkic Council) was founded on October 3, 2009, in Nakhchivan as an international organization to promote comprehensive cooperation among the Turkic States. The founding members of the Organization of Turkic States are Azerbaijan, Kazakhstan, Kyrgyzstan, and Turkey. The Organization of Turkic States was founded in November 2021 in the Turkic Council's 8th Summit in Istanbul. In this context, it is possible to say that the Organization of Turkic States has been the culmination of the "Heads of State Summits of Turkish Speaking Countries" since 1992. Kazakhstan is a distinguished member of the Organization of Turkic States. The stability and peace of Kazakhstan is of foremost importance not only in the context of Central Asia but also in terms of security and stability for the Turkic world. In this context, the developments that caused turmoil in Kazakhstan are closely followed by the Organization of Turkic States. We wish that the coming days will bring peace, tranquility and stability to Kazakhstan.

Defense Diplomacy Strategy in Global Governance to Face the Global Threats

Global developments that are full of dynamics are marked by the emergence of interdependence between countries. Global developments are in line with the development of science and technology which causes countries to seem borderless. The blurring of boundaries between countries and the development of an increasingly dynamic environment are also accompanied by the development of increasingly broad and multidimensional threats. This global development is also marked by the emergence of new actors in international relations. The development of threats and increasing global issues that cannot be handled by the state alone have created a new phenomenon in the international relations order, namely global governance. Previously, the state was the sole actor in the order of international relations. However, with global governance, there is a new arrangement in the international relations system that accommodates all actors who play a role. This research will use a qualitative phenomenological method. The theory used in this research are global governance, defense diplomacy and international organization as a basis theory and concept, and also a security theory as supporting theory. In the end, we can see that the change of international order can bring the positive effect for countries in achieving their national goals and accomplish their national interests.

COVID-19 Impact on International Migration

COVID 19 created many problems around the world and it affected everybody including migrants and immigrants. Many countries halted asylum seeker procedure in order to stop COVID 19 spreading but some countries restarted asylum seeker procedure since many people were in dangerous situation and they needed protection. Migrants and immigrants are highly vulnerable and can be infect by COVID 19. Many organizations especially international Organization played and are playing very important role to protect them against COVID 19. Migrants are working in frontline, they are in contact with other people, and the risks are very high to infect by COVID 19. Many of them hit globally very hard because of the COVID 19 especially due to the economic shut downs for example food, accommodating and personal services. Many countries closed their borders and they halted asylum seeker procedure. The number of restrictions and measures that imposed on migrants and immigrants reached 4600 around the world. Many countries have imposed travel ban especially on new comers.

Seasonal Variation of the Microbial Quality of Local Vegetables in Giresun, the Northern Province of Turkey

Consumption of vegetables, having a significant place in nutrition of humankind, is increasing day by day as their health-improving effects have been better understood nowadays. For such vegetables, certain criteria such as organic production, season production, regional production etc. are taken into consideration. The objective of this study is to research about existence of Bacillus cereus and Salmonella spp. in the locally-grown vegetables offered in local bazaars. Parsley, lettuce, spinach, turnip, carrot, chard, Brussels sprouts and radish produced in the province of Giresun were used in the study. Bacillus cereus and Salmonella spp. analyses were carried out in line with International Organization for Standardization quality standards. Among 89 vegetable samples analyses, Salmonella spp. and B. cereus were not detected in all and 5 of the samples respectively (

Global Eclectic Treatment of Covid-19: Global, Regional, and National Perspectives on Common Enemy

After being called the UN's, COVID-19 has become a global common enemy today. The escalation of the pandemic has been responded to nationally, regionally, as well as globally. However, the efforts of the United Nations as the most significant international organization are interpreted differently at the regional and national levels. That way, there will be a gap in understanding between the handling of COVID-19 at the global, regional, and national levels. Therefore, this paper discusses further how the COVID-19 as a common global enemy is reflected in regional and national actions against this pandemic? The global eclectic theory is explored to explain how global concepts relate to more specific concepts. Comparing the COVID-19 handling policies in ASEAN, SAARC, and the EU is needed to deeply explain the differences in handling the outbreak in each region. The result shows that common enemies do not automatically reflect joint regional action. National interest is still challenging to consolidate at the regional, furthermore global level. Moreover, cultural differences between countries cannot be reduced quickly in global matters.
