Gas flaring is a global issue but more especially for developing countries who are faced with various health and environmental challenges. This research paper focusses on the Niger Delta region of Nigeria, who are among the highest ranked for the amount of natural gas flared in the process of oil exploration and extraction. The study is aimed at reviewing the existing literatures, which will help
The ability to orient requires reliable cue information, and the primary cue used in straight-line orientation by the diurnal dung beetle Kheper lamarcki is the sun. It is previously known that the orientation precision of the dung beetle decreases at high solar elevations compared to lower elevations. In this study, the reliability of the sun compass was investigated in detail by testing the orie
People in Hong Kong continues to wrestle with the configuration of national identity and local distinctiveness, even though the fact of handover from the British to China was settled long ago. In the recent decade, several large-scale political protests have witnessed the hostile sentiments from Hong Kong people towards the central government and their shrinking attachments to the nation. The 2019
The aim of this study is to investigate whether crops are a mechanism through which drought affects terrorist activity. The theory suggests that drought can affect conflict if the group or country affected also is dependent on agriculture, experiences low economic development and is politically excluded. This study adds the perspective that decreased crop harvests, due to drought, can be understoo
The paper is based on an online field study, investigating Ukrainian civil society actors' perceptions of the peace processes regarding Donbas. The study builds on the premise of civil society's importance for peace processes. The study, therefore, investigates civil society perceptions by analysing frictional encounters between the civil society and international and local actors as seen
Smart City is a paradigm for the development of urban spaces through the implementation of state-of-the-art ICT. There are two main approaches when developing Smart Cities: top-down and bottom-up. Based on the bottom-up approach, the concepts of Smart People and Smart Communities have emerged as dimensions of the Smart City, advocating for the engagement of citizens in Smart People initiatives. Th
Today, waste water treatment plants do not remove pharmaceutical residues from the water (as there are currently no regulations for wastewater treatment in regards to pharmaceuticals residues in Sweden) resulting in a high concentration of pharmaceuticals reaching the environment. The Swedish environmental protection agency have recently concluded that there is a need for advanced treatment of pha
This thesis assesses the impact of innovation on employment, using a selection of International Patent Classifications (IPC) as proxies for technological development. It uses a 15-country, 8-sector and 15-year dynamic panel dataset, specifying a system Generalized Methods of Moments (GMM) econometric model to test this relationship. It specifically evaluates whether advances in robotics – measured
Identifying and keeping track of different structural representations of functionally overlapping issues is important in order to keep a well maintained issue management corpus, establishing efficient and organized response ability to develop and code software patches repairing these issues and defects. This is normally achieved by manual, time-costly reviewing-processes by special teams put up to
The Gaia space astrometry mission (to be launched in 2012) will use a continuously spinning spacecraft to construct a global system of positions, proper motions and absolute parallaxes from relative position measurements made in an astrometric focal plane. This astrometric reduction can be cast as a classical least-squares problem, and the adopted baseline method for its solution uses a simple ite
BL13-XALOC is currently the only macromolecular crystallography beamline at the 3 GeV ALBA synchrotron near Barcelona, Spain. The optics design is based on an in-vacuum undulator, a Si(111) channel-cut crystal monochromator and a pair of KB mirrors. It allows three main operation modes: a focused configuration, where both mirrors can focus the beam at the sample position to 52 mu m x 5.5 mu m FWHM
Quantum dots (QDs) and graphene are both promising materials for the development of new-generation optoelectronic devices. Towards this end, synergic assembly of these two building blocks is a key step but remains a challenge. Here, we show a one-step strategy for organizing QDs in a graphene matrix via interfacial self-assembly, leading to the formation of sandwiched hybrid QD-graphene nanofilms.
The Medipix detector is the first device dedicated to measuring mixed-field radiation in the CMS (Compact Muon Solenoid) experiment cavern and able to distinguish between different particle types. Medipix2-MXR chips bump bonded to silicon sensors with various neutron conversion layers developed by the IEAP CTU in Prague were successfully installed for the 2008 LHC start-up in the CMS experimental
The aim of this study was to investigate the effects of salting and different pre-salting procedures (injection and brining versus brining only) on the microstructure and water retention of heavy salted cod products. Salting resulted in shrinkage of fibre diameter and enlargement of inter-cellular space. Water was expelled from the muscle and a higher fraction became located in the extra-cellular
We investigate various mechanisms contributing to the surface ion distributions in simple and mixed aqueous alkali-halide solutions depending on the total salt concentration, using a combination of photoelectron spectroscopy and molecular dynamics simulations. In simple solutions, the surface enhancement of large polarizable anions is reduced with increasing concentration. In the case of a NaBr/Na
ABSTRACT: Genomic regions with altered gene expression are a characteristic feature of cancer cells. We present a novel method for identifying such regions in gene expression maps. This method is based on total variation (TV) minimization, a classical signal restoration technique. In systematic evaluations, we show that our method combines top-notch detection performance with an ability to delinea
Substitution in rutile-type approximate to SbVO4 was made with Fe3+ and Ga3+ replacing V3+, and Nb5+ replacing Sb5+. Moreover, preparations with Ti were synthesised where Ti4+ ions substitute for both V4+ and V3+/Sb5+ pairs approximate to SbVO4-related phases containing Ti together with Fe and Ga were also prepared. The samples were characterised using X-ray diffraction, DRIFT and Raman spectrosco
