Summary

Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today, it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems. Environmental studies are incorporating more of the social sciences in order to understand human relationships, perceptions and policies towards the environment.

Sustainable Development Goals
Sürdürülebilir kalkınma hedefleri (SDG'ler), 2015'te kabul edilen 17 hedefi içeren, BM'nin herkes için daha iyi ve daha sürdürülebilir bir gelecek elde etme planının küresel bir kalkınma programıdır. Yoksulluk, eşitsizlik, iklim değişikliği dahil olmak üzere küresel nüfusun karşılaştığı zorlukları ele alırlar. , çevresel bozulma, barış ve adalet. Programlar genellikle sürdürülebilir ekonomik büyümeyi ve sürdürülebilir kalkınma için 2030 gündemini uygulamak için sürdürülebilirliğin güçlendirilmesi modlarını vurgular. Bu SDG'lerden SDGS 7, 8, 9, 11, 12 ve 17, doğrudan ve/veya dolaylı olarak sürdürülebilirlik ve döngüsellik fenomeniyle bağlantılıdır. Birleşmiş Milletler'in (BM) SKH'lerine imza atan ülkelerdeki hükümetler, ulusal politika ve programlar da dahil olmak üzere farklı eylemlerde bulunarak hedefe ulaşılmasında çok önemli bir rol oynamaktadır,

Phosphodiesterase-5 (PDE-5) Inhibitors as Emergent Environmental Contaminants
Erectile dysfunction (ED) is an increasing disorder [16], affects 25 to 35 million men over 18 years in Europe. Pharmaceuticals used to reduce this disorder act as phosphodiesterase-5 (PDE-5) inhibitors, a family of enzymes typically active in cyclic guanosine monophosphate (cGMP) degradation. The inhibition of PDE-5 results in the intracellular accumulation of cGMP, which plays a central role in signal transduction and regulates several physiological responses.

Narrow- versus Wide-Ranged Ostrya Species
Four sympatric Ostrya species have different geographic range sizes. O. multinervis and O. rehderiana are narrow-ranged species with narrow potential geographical distributions. O. japonica and O. trichocarpa, both of which have wide potential geographical distributions, are wide-ranged species.

Sustainable Social and Economic Development of Russian Municipalities
Sustainable social and economic development of municipalities has been assessed in Russia. In Russia, the issue of improving socio-economic sustainability of municipalities in the region through the assessment of its indicators are particularly relevant. Regional policy measures to equalize the level of socio-economic development should be designed, taking into account the identified features of the territorial development of municipal districts.

Stand-Level Optimization
There is a vast backlog of conducted first commercial thinnings (FCTs) in Finland. The reasons are many, but probably the most crucial would be the lack of simultaneous economic incentives for participating agents, i.e., private forest owners and forest machine contractors. In this study an FCT was executed accruing to five predetermined management options: (1) Industrial wood thinning with only two timber assortments, pulpwood and saw logs, (2) Integrated procurement of industrial and energy wood, (3) Energy wood thinning solely consisting of delimbed stems, (4) Whole-tree energy wood thinning with an energy price of 3 € m−3 and (5) Whole-tree energy wood thinning with energy price of 8 € m−3. Then, a two-phase financial analysis consisting of stand-level optimization (private forest owners) and profitability assessment (contractor) was conducted in order to find out whether there would be simultaneous economic incentives for both participants of FCT. The stand-level optimization revealed the financially best management options for a private forest owner, and then, for a contractor, the profitability assessment exposed the profit (or loss) associated with the particular management option.

Sustainable Management by Rhizobacteria
Rhizobacteria are bacteria from diverse taxonomic genera, which are living in the rhizosphere of plants. Among the rhizobacterial bulk, several genera of bacteria have been proven for plant growth promotion are termed as ‘beneficial rhizobacteria’. There are various modes of action for plant growth promotion through the adoption of beneficial rhizobacteria. The beneficial bacteria also enhance tolerance in plants to various biotic and abiotic stresses caused by the global climate change.

Shade Covers in Water Reservoirs
Shade objects are small plastic spheres, squares or even hexagons floating on top of a water reserve for environmental reasons. The creator of shade balls in California originally used them to prevent chemical treatments in the reservoir from reacting with sunlight creating bromate, which is a carcinogen regulated by many institutions worldwide (chlorine plus sunlight turns bromine into bromate that is a potentially cancer-causing agent; because shady objects stop bromate from forming below, less chlorine is required to treat the water than without them). More recently, other environmental issues have been associated to the use of shade objects: slowing down water evaporation, preventing algae blooms, avoiding birds landing on bodies of water and promote water heating.

Decapods Crustaceans Amylase
Decapod crustaceans are a very diverse group and have evolved to adapt to a broad variety of diets. However, α-amylases have been more thoroughly studies in herbivore and omnivore species, both from an evolutionary/ecological and applied (i.e., aquaculture) point of view, while information on α-amylases from carnivorous species is scarce. Diverse studies revealed that enzyme sequences and overall architecture is highly conserved among decapods.

Toward a Feminist Agroecology
Agroecology is gaining ground as a movement, science, and set of practices designed to advance a food systems transformation which subverts the patterns of farmer exploitation currently entrenched in dominant agricultural models. A feminist agroecology focuses on redressing unequal gender relations as well as other intersecting relations of marginalization such as race, class, caste, and ethnic identity.
