The aim of this essay is to examine four floor mosaics from private dwellings in Pompeii. These 1st century floor mosaics decorate the fauces of the houses and they all depict watchdogs. The first question to be asked is if there are other common features between the houses that can explain why these house owners chose this figure. The second question is if you can reveal, from the existing knowle
The Rwandan genocide 1994 was a well-planned and ethnic based act that killed approximately 900 000 people. The UN and the colonial powers are getting much attention and are worldly discussed about the failure of interference before and during the genocide. In this study the history of colonial Rwanda will be analyzed and the UN relation will be discussed. This will be done by examining how th
According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billi
I detta arbete studeras hur word of mouth fungerar i praktiken. Word of mouth är passerande, verbal och informell information. I huvudsak handlar det om rekommendationer men även generell information från en person till en annan. Word of mouth är ett mänskligt fenomen som har funnits sedan urminnes tider då människor är kommunicerande varelser. På senare år har dock fenomenet word of mouth blivit
We have studied drug release and skin permeation from several different liquid crystalline lipid formulations that may be used to control the respective release rates. We have studied the release and permeation through human skin of a water-soluble and amphiphilic drug, propranolol hydrochloride, from several formulations prepared with monoolein and phytantriol as permeation enhancers and controll
Although estrogen receptor-alpha (ERalpha) is a marker used to identify breast cancer patients most likely to benefit from endocrine therapy, approximately 50% of ERalpha-positive breast carcinomas are resistant to tamoxifen. Preclinical studies have shown that phosphorylation of ERalpha at serine-118 (ERalphaS118-P) is required for tamoxifen-mediated inhibition of ERalpha-induced gene expression.
We show for the oppositely charged system poly(diallyldimethylammonium chloride)/sodium dodecyl sulfate that the cliff edge peak in its surface tension isotherm results from the comprehensive precipitation of bulk complexes into sediment, leaving a supernatant that is virtually transparent and a depleted adsorption layer at the air/water interface. The aggregation and settling processes take about
The chemokine CCL25 is selectively and constitutively expressed in the small intestinal epithelium and plays an important role in mediating lymphocyte recruitment to this site. In this study, we demonstrate that CCL25 expression in murine small intestinal epithelial cells is independent of signaling through the lymphotoxin 0 receptor and is not enhanced by inflammatory stimuli, pathways involved i
The formation and microstructure of a novel microemulsion based on a salt-free catanionic surfactant have been examined by considering the hexadecyltrimethylammonium octylsulfonate (TASo)-decane-D(2)O system and using small-angle neutron scattering and self-diffusion NMR. With focus on the emulsification failure boundary, o/w discrete droplets have been observed and characterized for all of the st
We show conclusively that multilayers at interfaces of an oppositely charged polyelectrolyte/surfactant system can result from the transport under gravity of bulk aggregates with internal molecular structure. This process was demonstrated by measurements of poly-(diallyldimethylammonium chloride)/sodium dodecyl sulfate solutions at the air/liquid and solid/liquid interfaces using neutron reflectom
In economic geography, geographical proximity has been identified as a key driver of M&A activity. In this context, little attention has yet been drawn to the effect of industrial relatedness, which refers to the similarity and complementarity of business activities. We examine 1,855 domestic M&A deals announced between 2002 and 2008 in the Netherlands, and we assess the extent to which ge
In the Democratic Republic of Congo (DRC), conflict-related sexual violence is widespread. The United Nations has made several efforts in combating this violence, for example adopting the United Nations Security Council Resolution 1820 from 2008. An interesting question is if these resolutions, which can be seen as a manifestation of an international norm that condemns sexual violence, can affect
A study done on the Harpy Tomb at Xanthus in ancient Lycia. This study is an experimental visibility analysis, the purpose of which is to explore to what extent the geometry of the bas-relief panels would be visible. Aspects which are taken into consideration for this purpose include distance and varying positions, as well as time of day. Using modern laser scanning technology and 3D processing so
Crowdfunding is often considered as a financial source to close the early stage financial gap of new ventures. However, there is little research on its impact regarding other liabilities new ventures face. The aim of this study is to find evidence on how crowdfunding can provide new ventures with additional value apart from financial resources. For this purpose, the concept of liability of newness
Sammanfattning Dold i samhällets uppbyggnad finns en undermedveten strukturell lönediskriminering. Internationell och nationell rätt är endast tillämplig på den individuella lönediskrimineringen, vilket innebär att den strukturella diskrimineringen per automatik tolereras. Kandidatuppsatsen utreder och ifrågasätter rättsläget vad gäller individuell lönediskriminering samt uppmärksammar den struktuAbstract Hidden in the construction of society lies subconscious structural wage discrimination. International and national law is only applicable on the individual wage discrimination, which means that the structural discrimination is automatically tolerated. The aim of this bachelor thesis is to investigate and question the current legislation regarding individual wage discrimination and highlig
We propose simple estimation of the location parameter for a density that is unbounded at the mode. The estimator maximizes a modified likelihood in which the singular term in the full likelihood is left out, whenever the parameter value approaches a neighborhood of the singularity location. The consistency and super-efficiency of this maximum leave-one-out likelihood estimator is shown through a
We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac
