The Effect of Halogen Bonding on the Packing of Bromine Substituted Pyridine and Benzyl Functionalized Resorcinarene Tetrapodands in the Solid State

2012

The synthesis and characterization of new bromine-substituted pyridine and benzyl functionalized tetramethoxy resorcinarene tetrapodands are described and their solid-state structural properties and interactions were studied by single crystal X-ray crystallography. Three different crystal structures were obtained for the pyridine derivative and one for the benzyl derivative, which revealed that the interactions of the bromine substituent have an explicit effect on the crystal packing of the resorcinarene molecules. One of the structures obtained had very interesting halogen–halogen interactions with the same geometry as is generally found for compounds used in nonlinear optical studies. pee…

Kriminālprocesa uzsākšanas tiesiskais regulējums

2019

Bakalaura darbs “Kriminālprocesa uzsākšanas tiesiskais regulējums” sniedz ieskatu kriminālprocesa uzsākšanas tiesiskajā regulējumā un ar to saistītajā problemātikā. Kriminālprocesa uzsākšanai ir pamatnozīme krimināltiesisko attiecību taisnīgā noregulējumā. Tas ir pamats turpmāko procesuālo darbību īstenošanai. Kriminālprocesam ir jākalpo tam, lai tiktu efektīvi piemērotas krimināltiesību normas un taisnīgi noregulētas krimināltiesiskās attiecības. Bakalaura darba mērķis ir izprast kriminālprocesa un kriminālprocesa uzsākšanas jēdzienus. Izpētīt kriminālprocesa uzsākšanas tiesisko regulējumu. Apskatīt gadījumus, kad tiek atteikts uzsākt kriminālprocesu, kā arī iepazīties ar tiesībzinātnieku …

Optimal Resource Allocation in Multi-Hop Networks: Contention vs. Scheduling

2014

CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) is actually the most used method in ad-hoc networks for transmitting on a contending medium, even if it shows poor performance in presence of hidden nodes. To increase performance, we propose an algorithm that combines CSMA and TDMA (Time Division Multiple Access) approaches. The adopted solution consists of grouping contending nodes in non-interfering subsets and granting a different numbers of time slots to different groups, while using the CSMA to manage medium access among nodes belonging to the same subset. An optimization procedure to assign the time slots to each subset of nodes and to find an equilibrium between contention …

Lake size and fish diversity determine resource use and trophic position of a top predator in high-latitude lakes

2015

Prey preference of top predators and energy flow across habitat boundaries are of fundamental importance for structure and function of aquatic and terrestrial ecosystems, as they may have strong effects on production, species diversity, and food-web stability. In lakes, littoral and pelagic food-web compartments are typically coupled and controlled by generalist fish top predators. However, the extent and determinants of such coupling remains a topical area of ecological research and is largely unknown in oligotrophic high-latitude lakes. We analyzed food-web structure and resource use by a generalist top predator, the Arctic charr Salvelinus alpinus (L.), in 17 oligotrophic subarctic lakes…

GREEN LOGISTICS – A DIFFERENT AND SUSTAINABLE BUSINESS GROWTH MODEL

2014

Built on the concepts of green logistics and green supply chain management (GrSCM), this paper presents the relationship between logistical activities and its related environmental effects and costs. By greening their supply chain, companies can better use their assets, optimize resources- do more with less, improve and create sustainable technology, ensure continuity and strategic, long-term alliances. Business ethics and social responsibility are important components of organisational effectiveness. Most companies recognize that socially responsible activities improve their image among consumers, stakeholders, the financial community and other relevant publics. They have found that enviro…

Switching spatial scale reveals dominance-dependent social foraging tactics in a wild primate

2017

When foraging in a social group, individuals are faced with the choice of sampling their environment directly or exploiting the discoveries of others. The evolutionary dynamics of this trade-off have been explored mathematically through the producer-scrounger game, which has highlighted socially exploitative behaviours as a major potential cost of group living. However, our understanding of the tight interplay that can exist between social dominance and scrounging behaviour is limited. To date, only two theoretical studies have explored this relationship systematically, demonstrating that because scrounging requires joining a competitor at a resource, it should become exclusive to high-rank…

Social innovation in a post-conflict setting : examining external factors affecting social service NGOs

2021

While the study of the influence of external environmental factors on non-governmental organizations (NGOs) is well explored in the international development literature, the importance of these factors on NGOs’ transformative roles in a post-conflict development setting remains less understood. Nevertheless, external environmental factors could have a crucial impact on NGOs in such a context, especially when NGOs want to integrate a socially innovative approach into the social services they provide. Using survey data of staff members of social service NGOs from post-conflict Bosnia and Herzegovina (N = 120) and applying resource dependence theory, this study identifies three environmental f…
