Abstract: The purpose of the paper is to analyze the informal economy in Albania. The measurement of informal economy may be realized through direct and indirect methods. The collection of data about informal economic activities, the frequency and the volume of the underground activities present a challenge, because of the data limitations. Therefore, to measure it used more indirect methods. Albanian governments have always adopted a philosophy that aims to formalize the economy through legal and institutional improvements, reducing taxes, fighting corruption and tax evasion; improvement in revenue collection from customs and taxes in general, improving governance and increasing efficiency of public institutions. Albania is on the way of the integration in the EU. The integration perspective should be supported by concrete politics on the improvement of government functioning and decrease of the informal sector, so that the people think that their country is on the right way toward modernization and prosperity.
Western Amazonian Ateleutina (Hymenoptera, Ichneumonidae, Cryptinae)
Santiago Bordera,llari Saaksjarvi
Journal of Hymenoptera Research , 2012, DOI: 10.3897/jhr.29.3661
Abstract: Ateleutina is a small subtribe of Cryptinae (Ichneumonidae) composed of two genera: Ateleute F rster and Tamaulipeca Kasparyan. Neither of the genera includes species described from South America. In this article five new species of Ateleute (A. ashaninka sp. n. and A. amarakaeri from Peru, A. shuar sp. n. from Ecuador and Peru, and A. huaorani sp. n. and A. kichua sp. n. from Ecuador) and three new species of Tamaulipeca (T. bora sp. n. from Ecuador and Peru, T. candoshi sp. n. from Ecuador and T. matses sp. n. from Peru) are described and illustrated from Western Amazonia. Identification keys to the known South American species of the genera are provided.
A new species of Lathrolestes (Hymenoptera, Ichneumonidae) from Ecuadorian Amazonia, with a key to the Neotropical species of the genus

ZooKeys , 2012, DOI: 10.3897/zookeys.251.3709
Abstract: Here we describe and illustrate a new parasitoid wasp species, Lathrolestes gauldi sp. n. from the lowland rainforest of eastern Ecuador and provide a key to the Neotropical species of the genus. This is the first record of the subfamily Ctenopelmatinae from Ecuador.
Technological Progress in Radiation Therapy for Brain Tumors  [PDF]
Frederik Jozef Vernimmen, Kathy Rock
Journal of Cancer Therapy (JCT) , 2014, DOI: 10.4236/jct.2014.51005

To achieve a good therapeutic ratio the radiation dose to the tumor should be as high as possible with the lowest possible dose to the surrounding normal tissue. This is especially the case for brain tumors. Technological advancements in diagnostic imaging, dose calculations, and radiation delivery systems, combined with a better understanding of the pathophysiology of brain tumors have led to improvements in the therapeutic results. The widely used technology of delivering 3-D conformal therapy with photon beams (gamma rays) produced by Linear Accelerators has progressed into the use of Intensity modulated radiation therapy (IMRT). Particle beams have been used for several decades for radiotherapy because of their favorable depth dose characteristics. The introduction of clinically dedicated proton beam therapy facilities has improved the access for cancer patients to this treatment. Proton therapy is of particular interest for pediatric malignancies. These technical improvements are further enhanced by the evolution in tumor physiology imaging which allows for improved delineation of the tumor. This in turn opens the potential to adjust the radiation dose to maximize the radiobiological effects. The advances in both imaging and radiation therapy delivery will be discussed.

Gold Nanoparticles in Stereotactic Radiosurgery for Cerebral Arteriovenous Malformations  [PDF]
Frederik Vernimmen, Mikhail L. Shmatov
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2015, DOI: 10.4236/jbnb.2015.63019
Abstract: Objective of the study: To explore the potential for therapeutic gain with gold nanoparticles in arteriovenous malformation radiosurgery based on their interaction with photons and protons. Study methods: Radiation dose enhancement resulting from the interaction of gold nanoparticles with irradiation ranging from kilovoltage to megavoltage photons and protons was researched in the literature. The role of angiogenesis and its regulation via vascular endothelial growth factors and cell membrane receptors, especially for endothelial cells in arteriovenous malformations, was investigated as a way for selective arteriovenous malformation deposition. Results: Radiation dose enhancement with gold nanoparticles is described in the literature but has so far only been investigated for its potential in treating malignancies. Because of the high atomic number of gold (Z = 79), dose enhancement occurs with photons mainly based on secondary photon and Auger electron production and the dose enhancement factor is the highest for irradiation with kilo voltage photons. Dose enhancement happens with megavoltage photons also but to a lesser extend and is mainly due to the ionization of gold by secondary photons and electrons generated by the megavoltage photons passing through tissue. The range of the secondary photo electrons emitted by gold is sufficient to cover the entire endothelial cell content. Protons interact with the production of Auger electrons which have a very short range, insufficient to cover the entire contents of endothelial cells, but sufficient to cause a high cell membrane dose for membrane located gold nanoparticles (AuNPs). Arteriovenous malformations are dynamic entities with angiogenesis taking place. This is reflected by a different expression of angiogenic receptors on the membrane of arteriovenous malformation endothelial cells compared to normal brain blood vessels, thereby opening the opportunity for selective deposition of such particles. For the use in proton therapy a new definition for the dose enhancement factor describing the local effect of nanoparticles is proposed. Conclusion: The concept of nanoparticle enhanced radiosurgery for arteriovenous malfor-mations by selective deposition of gold nanoparticles is a novel approach. The local dose enhancement opens the way for therapeutic gain which in turn could lead to improved obliteration rates and/or a shorter latent period.
Two new species of Xanthopimpla (Hymenoptera: Ichneumonidae) from Western Amazonia, with a revised key to the Neotropical species of the genus
Isrrael Gómez,llari Saaksjarvi,Anu Veijalainen,Gavin Broad
ZooKeys , 2009, DOI: 10.3897/zookeys.14.193
Abstract: Xanthopimpla Saussure, 1892 is one of the largest genera of the family Ichneumonidae. The genus is very species rich in Indo-Australia but poorly represented in the Neotropical region. In this paper two morphologically very distinctive species of the genus, X. amazonica sp.n. Gómez, S ksj rvi & Veijalainen, and X. jussilai sp.n. Veijalainen, S ksj rvi & Broad, are described and illustrated. The new species have been collected in the Peruvian and Ecuadorean Amazonia. A revised key to the Neotropical species of the genus is provided. X. aurita Krieger and X. craspedoptera Krieger are recorded for the first time from Peru.
