Aneurysmal dilatation of the aortic sinuses of Valsalva has been most extensively documented in the setting of aortopathies, particularly Marfan syndrome. On the other hand, there is limited data in the literature about congenital sinus of Valsalva aneurysms outside this context. For the purpose of this review, we carried out a literature search on aneurysmal dilatation of the sinuses of Valsalva in Marfan syndrome, and compared this with congenital sinus of Valsaiva aneurysms, also including data from a case series from our institution. In conclusion, there are differences in management of aortic dilatation in Marfan syndrome and congenital sinus of Valsalva aneurysms. Though less weil-recognised, congenital aneurysms are often associated with significant morbidity and mortality and timely intervention is necessary.

Polymer optical fibres(POFs) have historically been regarded as a poor relation to their silica counterparts because of their higher attenuation, but they also have a number of advantages, particularly when coupled with a range of properties that can be produced using microstructures. In terms of their mechanical properties, they are lighter, remain flexible at large core sizes and can be stretched well beyond 30% without breakage. They are also biocompatible, they do not produce dangerous shards,and their low processing temperatures allow functionalized organic materials to be incorporated without decomposition. Other advantages for specific applications include better transmission properties(in the THz region) and the possibility of refractive indices that are close to that of water.

In this investigation, we focus on the current energy sources and future projects situation in East Africa up to 2040. Electricity generation potential of energy mix and electrical capacity will be analyzed. For both electricity generation and electrical capacity, the data source shows that some forms of energies such bio-energy, solar PV, etc. will contribute less as well as with insignificant contribution of nuclear energy. Whereas hydro is dominating comparing with gas, oil, coal, solar PV, bio-energy and other renewables energies. From 2000 up to 2012, hydro and oil were only the one source of electricity generation. Starting from 2020, other forms of energies will appear and continue to increase at different rate. The international trade of electricity in this region will appear in 2020 and continue to increase as predicted by the data. Up to 2040, hydro will play a big role in electricity generation with other renewable energy sources, such as coal, oil, Gas, bio- energy and solar PV that will continue to increase at different rate. The share of solar PV in energy generation will slowly increase compared to other sources. The capacity of hydro and renewable energy sources will be high compared with other sources of energy such as bioenergy, coal, oil, PV solar, and gas. The results show also that bio-energy will increase slowly in electricity generation in comparison with other source of energies. The present report shows that oil will continue to emit a lot carbon dioxide compared to gas and coal. The emission of CO2 from total final consumption (TFC) of oil will continue to be high in comparing with CO2 emission from power generation (PG) of oil. But the emission of carbon dioxide from power generation of coal from 2025 until 2040 will be high compared with emission of CO2 generated from FTC of coal. In this period, the emission from TFC for gas will remain insignificant. The total final consumption emission of oil in general

In this study we analyzed the generation and the potential of the electricity capacity of energy mix in East Africa from 2020 to 2040 including CO2 emission. The predicted results show that the electricity generated from hydro will dominate compared to gas, oil, coal, Solar PV, bio-energy and other renewable energy. Some forms of energies such as bio-energy, solar PV will contribute less, while the contribution of nuclear will remain insignificant. The oil will continue to emit a lot carbon dioxides compared to the emission from gas and coal. The emission of CO2 from total final consumption (TFC) of oil will be high compared to its emission from power generation (PG) of oil. More importantly, the results show a linear relationship between the energy outlook and time. This approach of modeling the energy in a linear form simplifies significantly the analysis of the electricity generation and capacity. Due to this high emission of CO2, a new policy and a transition from conventional to renewable should be implemented with clean and energy efficiency technology.

A kind of microstructured polymer optical fiber with elliptical core has been fabricated by adopting insitu chemical polymerization technology and the secondary sleeving draw-stretching technique. Microscope photography demonstrates the clear hole-structure retained in the fiber. Though the holes distortion is visible, initial laser experiment indicates that light can be strongly confined in the elliptical core region, and the mode field is split obviously and presents the multi-mode characteristic. Numerical modeling is carried out for the real fiber with the measured parameters, including the external diameter of 150 μm, the average holes diameter of 3.3 μm, and the average hole spacing of 6.3 μm by using full-vector plane wave method. The guided mode fields of the numerical simulation are consistent with the experiment result. This fiber shows the strong multi-mode and weak birefringence in the visible and near-infrared band, and has possibility for achieving the fiber mode convertors, mode selective couplers and so on.
