The Concept of Sustainable Development and Its Impact on the Shaping of Modern International Relations through Global Agreements

The goal of this article is a depiction of the process of the molding of the concept of sustainable development as well as a look at the influence that this concept has exerted on contemporary international politics, especially taking into account agreements of worldwide scope. This article is also an effort at demonstrating that the foundations of the concept of sustainable development can be traced to certain economic theories. The final section of this article is devoted to the characteristics of individual conferences initiated by the United Nations in order to promote enduring and sustainable development on a world scale. Also presented are the achievements of the individual conferences and their roles in demarcating universally obligatory principles and standards of sustainable development.Celem niniejszego artykułu jest scharakteryzowanie genezy kształtowania się Koncepcji Zrównoważonego Rozwoju, a także wskazanie, jaki wpływ miała ona na ukształtowanie się stosunków międzynarodowych w zakresie ochrony środowiska i rozwiązywania problemów społecznych. Przedmiotem analizy są także teorie ekonomiczne, które stały się fundamentem dla wykrystalizowania się koncepcji zrównoważonego rozwoju. Poniższy artykuł jest także próbą wykazania, iż konferencje organizowane przez ONZ na rzecz trwałego i zrównoważonego rozwoju, stały się siła napędową do rozpowszechnienia tej koncepcji w skali światowej

Effect of photoperiod on sexual activity of boar

The main objective of this study was to assess the effect of photoperiod on sexual activity of three breeds of boars: Swedish Landrace (n=34), Large White (n=38), and Duroc (n=32). Boar sexual activity was analysed based on the libido index and intensity of ejaculation. The libido index was calculated as the ratio between the duration of ejaculation and time of preparation until ejaculation. The intensity of ejaculation was the volume of ejaculate (mL) secreted in the unit of time (min). The effect of photoperiod was analysed as the effect of duration of daylight ( lt 12 h and >12 h) within photoperiod intervals (increasing and decreasing). Impact assessment was carried out by applying the General Linear Model procedure. Libido and intensity of ejaculation varied under the impact of photoperiod and the breed of boars. With the increase in age, the boar libido weakened, while the volume of ejaculate and intensity of ejaculation increased. Boars manifested better libido when the daylight lasted longer than 12 h in both photoperiod intervals. Different from libido, the volume of ejaculate and intensity of ejaculation were highest when the daylight was shorter than 12 h, but only in the decreasing photoperiod interval. Swedish Landrace boars manifested best libido, while in the production of sperm the Duroc boars were inferior compared with Swedish Landrace and Large White. The phenotypic relationship among libido, ejaculate volume, and ejaculation intensity ranges from very low to high; however, the coefficients were positive, which indicates the possibility of simultaneous improvement of these traits

Characterization of the LM5 pectic galactan epitope with synthetic analogues of β-1,4-d-galactotetraose

Plant cell wall glycans are important polymers that are crucial to plant development and serve as an important source of sustainable biomass. The study of polysaccharides in the plant cell wall relies heavily on monoclonal antibodies for localization and visualization of glycans, using e.g. Immunofluorescent microscopy. Here, we describe the detailed epitope mapping of the mab LM5 that is shown to bind to a minimum of three sugar residues at the non-reducing end of linear beta-1,4-linked galactan. The study uses de novo synthetic analogs of galactans combined with carbohydrate microarray and competitive inhibition ELISA for analysis of antibody-carbohydrate interactions

Nexus between Nuclear Energy Consumption and Carbon Footprint in Asia Pacific Region: Policy toward Environmental Sustainability

The distribution of energy sources is regarded to be an act of compassion in many of the Sustainable Development Goals outlined by the United Nations. In order to build a firm foundation for competitiveness and prosperity, nations should maintain equilibrium with the three key aspects of the global energy trilemma, which are energy affordability, energy access, and ecological balance. In light of this, the purpose of this research was to investigate the impact that nuclear energy, technological advancements, renewable energy, non-renewable energy, and natural resources have had on carbon footprints. We selected the top five nuclear energy countries by consumption in the Asia Pacific region, including China, India, Japan, Pakistan, and South Korea. We devised an exhaustive and all-encompassing empirical inquiry and used contemporary econometric methods. The second-generation panel’s long-run cointegration promotes the idea of long-term relationships between the series. According to the data, using nuclear and renewable sources of energy significantly contributes to an improvement in environmental quality. On the other hand, advancements in technology and the use of energy sources that do not replenish themselves considerably decrease environmental sustainability. In addition, natural resources end up playing a negative role in the long term. The results of the panel’s investigation into the chain of events that led to the development of nuclear power showed that the chain of events was unidirectional. In addition, there is causality that runs in both directions between technological innovation, renewable energy sources, non-renewable energy sources, and natural resources that have a carbon footprint. In light of this, it is recommended that these countries should combine energy policy actions and build energy strategy consistency by harmonizing the essential features of global nuclear energy in order to aid in the development of a well-calibrated energy structure
