Das japanische Unternehmen GC feiert 2016 fast ein Jahrhundert Lösungskompetenz im Bereich Zementierung: Vor 95 Jahren gründeten 3 junge Chemiker das GC Chemicals Research Laboratory nahe Tokio. Zwar konnte sich ihre 1. Materialentwicklung, ein Standardzement, noch nicht am Markt etablieren – doch dies befeuerte den I…
MALDI-TOF MS: is it all bells and whistles Our experiences with the MALDI-TOF MS since 2011 Outbreak of an exotic herpesvirus affecting oysters in Tasmania Using genomics to track and reduce foodborne disease in Australia 'The Pertussis Perplex -Shifting Schedules and Strategies' Bacteriophage formulated into a range…

(2011) The corrected Kg values are reported in an erratum included in the revised version of the original report. The revised report can be referenced as follows: Pier…
Scientific Reports 6: Article number: 23189; published online: 23 March 2016; updated: 02 September 2016 This Article has been retracted by the authors. The data presented in Figures 1e, 1g, 1h, 2b-d, 4a-b, 4d-e, 6a-b and 7a-b were manipulated and are duplicated in other papers 1,2,3,4,5 . All authors acknowledge thes…
A natural spiral antenna has a circumference of greater than one wavelength at the operating frequency. The currents on the spiral arms flow in a traveling wave fashion with a positive phase constant. Therefore, the polarization of the radiation is uniquely determined by the winding direction of the spiral arms, that…

Treatments for unwanted bone fractures have different limitations like potential infection risks and requirement of secondary surgery. Polymeric tissue engineering scaffold material can be a suitable alternative treatment device for the bone tissue regeneration due to its excellent biocompatibility, mechanical propert…
The work centred on the one-pot microwave-assisted polyol synthesis of undoped and Fe- and Al-doped ZnO nanoparticles from zinc acetate precursor diethylene glycol (DEG) solution in 15 minutes. The microwave reactor is advantageous over conventional heating due to its rapid and uniform heating of the reaction mixtures…
Petroleum based food packaging materials increase the global carbon footprint due to their non-biodegradability. Moreover, the excessive use and improper disposal have caused enough harm to the aquatic and terrestrial lives. According to the European Parliament, the usage of single-use plastics (mainly used for food p…
Varios tratamentos para desordens neurologicas sao malsucedidos por nao poderem atingir efetivamente o Sistema Nervoso Central (SNC). A presenca da barreira hematoencefalica (BHE) dificulta esse acesso e muitas substâncias sao incapazes de atravessa-la quando empregadas sem qualquer modificacao quimica ou fisico-quimi…
Tujuan dari optimasi pemakaian mata bor yang akan digunakan pada operasi pemboran yaitu untuk memilih jenis mata bor yang memiliki kinerja terbaik serta ekonomis. Sehingga, diharapkan mata bor tersebut dapat digunakan seoptimal mungkin dengan laju penembusan maksimal, waktu yang relatif singkat serta biaya operasi pem…
In this thesis we studied a series of nickel catalysts supported on alumina, with varying nickel loading (40-90% wt) for the transformation of waste cooking oils into renewable diesel (Green Diesel), through selective deoxygenation achieved by hydroprocessing. For comparison the catalysts were tested under the same co…
The objective of this research was to evaluate the in vitro corrosion behavior of experimental alloys Ti-Zr, with and without surface treatment, compared to commercially available alloys. For the electrochemical assay (n = 3) were made 48 Ticp discs, Ti-6Al-4V, Ti-5Zr, Ti-10Zr and Ti-15Zr, which were applied patterns…
La compréhension des enzymes et de leurs mécanismes catalytiques est d'une grande importance dans le développement de médicaments plus efficaces Pour mieux appréhender ces phénomènes, différentes approches théoriques comme les méthodes QM, MM-MD et QM/MM, peuvent être utilisées. L'objectif principal de cette thèse est…
Steel is of utmost importance for each national economy. One of the benchmarks of industrial development of the country is production and consumption of steel. 1 Production and consumption of concrete and ferrous materials (steel and cast iron) dominate over other groups of technical materials. It is believed that the…
In this study, flax and hemp fibres were assessed as raw materials for air-laying nonwoven fabrication. We are therefore hypothesizing that through proper production processes, the competiveness of flax and hemp fibre based nonwovens can be significantly improved. We anticipate improving the material properties by adj…
Friction welding is a solid-state welding that produces weld without the addition of filler material. This study presents results of friction welding dissimilar material SUH 3 and SUH 35 with variation of process parameters: spindle rotation speed (v), friction force (F1), and friction time (T1). These parameters are…
The main goal of this research was to carry out the reduction of graphene oxide ( GO ) to graphene ( rGO ) by using olive leaf extract ( ELM ) . Reduction was carried out with different amounts of ELM. The sample obtained by using the smaller ratio ELM/GO was rGO1, while the sample obtained byusing higher ratio of ELM…
Tese de doutoramento em Engenharia Mecânica, na especialidade de Materiais Energéticos e Sistemas de Conversão de Energia, apresentada ao Departamento de Engenharia Mecânica da Faculdade de Ciências e Tecnologia da Universidade de Coimbra
It is known the necessity to change the earthquake resistant design methods to take the control of structural performance and therefore, it is been included new concepts aimed to support the functions and to keep the structural properties and moreover to preserve safety lives. Taking advantage of visual representation…
