Abstract:
problem: little is known about the burden of influenza in sub-saharan africa. routine influenza surveillance is key to getting a better understanding of the impact of acute respiratory infections on sub-saharan african populations. approach: a project known as strengthening influenza sentinel surveillance in africa (sisa) was launched in angola, cameroon, ghana, nigeria, rwanda, senegal, sierra leone and zambia to help improve influenza sentinel surveillance, including both epidemiological and virological data collection, and to develop routine national, regional and international reporting mechanisms. these countries received technical support through remote supervision and onsite visits. consultants worked closely with health ministries, the world health organization, national influenza laboratories and other stakeholders involved in influenza surveillance local setting: influenza surveillance systems in the target countries were in different stages of development when sisa was launched. senegal, for instance, had conducted virological surveillance for years, whereas sierra leone had no surveillance activity at all. relevant changes: working documents such as national surveillance protocols and procedures were developed or updated and training for sentinel site staff and data managers was organized. lessons learnt: targeted support to countries can help them strengthen national influenza surveillance, but long-term sustainability can only be achieved with external funding and strong national government leadership.

Abstract:
Multiferroic BiFe_{1-x}Cr_{x}O_{3} (x = 0.2 and 0.4) ceramics were synthesized in a single phase. The effects of
Cr^{3+} substitution on the crystal structure, dielectric permittivity
and leakage current were investigated. Preliminary X-ray structural studies
revealed that the samples had a rhombohedral perovskite crystal structure. The
dielectric constant ε' significantly increased
while the dielectric loss tanδ was substantially
decreased with the increase in Cr^{3+} substitution. The temperature
effect on the dielectric properties exhibited an anomaly corresponding to
magneto-electric coupling in the samples and was shifted to lower temperatures
with the increase in Cr^{3+} substitution. The leakage current density also
reduced in magnitude with the increase in the Cr^{3+} substitution.

Abstract:
We investigate the FFT (Fast Fourier Transform) model and G-CSF (granulocyte colony-stimulating factor) treatment of CN (Cyclical Neutropenia). We collect grey collies and normal dog’s data from CN and analyze the G-CSF treatment. The model develops the dynamics of circulating blood cells before and after the G-CSF treatment. This is quite natural and useful for the collection of laboratory data for investigation. The proposed interventions are practical. This reduces the quantity of G-CSF required for potential maintenance. This model gives us good result in treatment. The changes would be practical and reduce the risk side as well as the cost of treatment in G-CSF.

Abstract:
Restructured electric market environment allows the power wheeling transactions between the power producers and customers to meet the growing load demand. This will lead to the possible of congestion in the transmission lines. The possible contingencies of power components further worsen the scenario. This paper describes the methodology for the identification of critical transmission line by computing the real power and reactive power performance indices. It also demonstrates the importance of fuzzy logic technique used to rank the transmission lines according to the severity and demonstrated on IEEE-30 bus system.

Abstract:
In scaled CMOS processes,
the single-event effects generate missing output pulses in Delay-Locked Loop
(DLL). Due to its effective sequence detection of the missing pulses in the
proposed Error Correction Circuit (ECC) and its portability to be applied to
any DLL type, the ECC mitigates the impact of single-event effects and
completes its operation with less design complexity without any concern about losing
the information. The ECC has been implemented in 180 nm CMOS process and
measured the accuracy of mitigation on simulations at LETs up to 100 MeV-cm^{2}/mg.
The robustness and portability of the mitigation technique are validated
through the results obtained by implementing proposed ECC in XilinxArtix 7
FPGA.

Abstract:
Power generation becomes the need of developed, developing and under developed countries to meet their increasing power requirements. When affordability increases their requirement of power increases, this happens when increased per capita consumption. The existing power scenario states that highest power is produced using firing of coals called thermal energy. A high efficiency Switched Reluctance Generator (SRG) based high frequency switching scheme to enhance the output for grid connectivity is designed, fabricated and evaluated. This proposed method generates the output for the low wind speed. It provides output at low speed because of multi-level DC-DC converter and storage system. It is an efficient solution for low wind power generation. The real time readings and results are discussed.

Abstract:
In this paper, we will derive the following formula for the value of the gravitational constant G: (1). This equation has only 0.81% error compared to the common accepted value [1]. The parameters in the equation are the following: the fine structure constant, qthe elementary charge, the mass of the electron, the permittivity of the free space, ethe exponential function and the relation between a circumference and its diameter. Values attached:[2],

Abstract:
The fine-structure constant α [1] is a constant in physics that plays a fundamental role in the electromagnetic interaction. It is a dimensionless constant, defined as: (1)
being q the elementary charge, ε0 the vacuum permittivity, h the Planck constant and c the speed of light in vacuum. The value shown in (1) is according CODATA 2014 [2].
In this paper, it will be explained that the fine-structure constant is one of the roots of the following equation: (2)
being e the mathematical constant e (the base of the natural logarithm). One of the solutions of this equation is: (3)
This means that it is equal to the CODATA value in nine decimal digits (or the seven most significant ones if you prefer). And therefore, the difference between both values is: (4)
This coincidence is higher in orders of magnitude than the commonly accepted necessary to validate a theory towards experimentation.
As the cosine function is periodical, the Equation (2) has infinite roots and could seem the coincidence is just by chance. But as it will be shown in the paper, the separation among the different solutions is sufficiently high to disregard this possibility.
It will also be shown that another elegant way to show Equation (2) is the following (being i the imaginary unit): (5)
having of course the same root (3). The possible meaning of this other representation (5) will be explained.
