Dermatoglyphics and Cheiloscopy Pattern in Hypertensive Patients; A Study in Ahmadu Bello University

Essential hypertension is sustained high blood pressure not attributable to a single cause but reflecting the interaction of multiple genetic and environmental influences. Dermatoglyphic involves the study of epidermal ridges present on the surface of palms, finger, soles and toes while cheiloscopy is the study of the grooves or furrows present on the vermilion border of the human lips. Finger and lip prints are known useful genetic markers in some congenital and clinical diseases; as such this study was aimed at determining the association between fingerprint and lip print patterns in hypertensive patients. The present study was carried out with hypertensive patients attending the outpatient clinic of Ahmadu Bello University Teaching Hospital (ABUTH), Zaria and was compared with a control group with normal blood pressure.

Stability Analysis of AC Transmission Line Using FACTS

Due to the rapid technological progress, the consumption of electric energy increases continuously. But the transmission systems are not extended to the same extent because building of new lines is difficult for environmental as well as political reasons. Hence, the systems are driven closer to their limits resulting in congestions and critical situations endangering the system security. Power Flow Control devices such as Flexible AC Transmission Systems (FACTS) provide the opportunity to influence power flows and voltages and therefore to enhance system security, e.g. by resolving congestions and improving the voltage profile. Several kinds of FACTS controllers have been commissioned in various parts of the world. This paper presents various types of FACTS devices such as: load tap changers, phase-angle regulators, static VAR compensators, thyristorcontrolled series compensators, interphase power controllers, static compensators, and unified power flow controllers.

Detection and analysis of leaf curl virus from Jatropha

Geminiviruses are a group of plant viruses that contain circular single stranded (ss) DNA genomes encapsidated in small twinned icosahedral capsids .The virus DNA A plus strand encodes the coat protein (CP/AV1) essential for viral transmission by whiteflies (Bemisia tabaci)[4]. Jatropha has been found to have strong molluscicidal activity and the latex to be strongly inhibitory to watermelon mosaic virus. It is also listed as a homicide, piscicide and raticide. Jatropha is considered as a poor quality fuelwood since the soft wood burns too rapidly. In Africa, Jatropha is widely planted as a “living fence” and hedgerows to protect food crops from damage by livestock and as a windbreak to prevent soil erosion moisture depletion. In Madagascar, Jatropha is used as a support plant for Vanilla. Jatropha is grown both as a vegetable and a spice crop[1]. Out of the 22 viruses infecting jatropha, mosaic and leaf curl disease are the most devastating.[5]Virus type--Single stranded DNA virus

H-Bridge Multi Level STATCOM under Different Loads

Voltage control and fast reactive power compensation are two main application area of Static Synchronous Compensator (STATCOM), which is a shunt connected voltage source converter (VSC) based FACTs controller using power semiconductor devices (particularly IGBT, GTO etc.).However, the total Statcom circuitry has complex and coupled system dynamics which require advanced controllers to achieve well performance. In our paper, we have represented a sixty pulse VSC for producing higher pulse number by combining a twelve pulse converter with a five level VSI in order to obtain the overall performance of the said VSC in a three phase system. As the number of levels increases in the VSI of the Statcom, it will produce a staircase wave with lower value of THD. The simulation results are presented and it is observed that the STATCOM shows excellent response to step change in the reactive current reference & the value of THD is also within the acceptable limit.

Power and Delay Optimized Edge Triggered Flip-Flop for low power microcontrollers.

The demand for low power circuit design has increased tremendously due to explosive growth of battery operated portable devices like Microcontroller.Microcontroller uses register blocks that are inturn consists of flip flops. The mandate to reduce system power consumption and design energy-efficient ICs has led to the increasing use of low-power IC design techniques that prolong the battery life. In this paper, a novel highly efficient power and delay optimized True Single Phase clocked (TPSC) edge triggered flip-flop has been proposed. The proposed circuit uses lesser number of transistors than the conventional transmission gate D flip-flop that reduce the overall power and delay.The proposed design is also free from both glitch and charge sharing problems making it suitable for high speed and low power applications. The circuits are simulated in TANNER EDA simulation tool using PTM 180nm technology files to compare the performance of proposed circuit with the existing ones. The circu

Changes in levels of hydrogen peroxide and phenolic compounds in grapevine latent buds during the an

The quantitative analysis of phenolic compounds and of hydrogen peroxide (H2O2) amounts in the latent buds of the vine (Vitis vinifiera. L) showed seasonal variations. These compounds change also as function of the vine development cycle. The total amounts of phenolic compounds are strongly accumulated in the buds in beginning of dormancy phase in midAugust. Nevertheless, the ending of dormancy phase in midNovember in the buds is associated with increasing of the hydrogen peroxide yield and a considerable drop in the content of the total amount of phenolic compounds. These variations appear to be strictly related to the climatic conditions. This is particularly visible in ending of dormancy phase. This is coinciding with the cold period where the temperature is below 10 ° C for at least 7 consecutive days.

Key Management Scheme for Efficient Group Communication Networks

- In most of the emerging networks the main problem is based on broadcasting a data to a remote cooperative group in efficient and secure manner. To overcome the limited communication from the group to the sender, the unavailability of fully trusted key generation center and the dynamics of the sender we proposing a hybrid of traditional broadcast encryption and group key agreement. In this system, each member maintains a single public/secret key pair. When seeing the public keys of the members, a remote sender can securely broadcast to any subgroup. Following this model, we introduce a scheme that is proven secure in the standard model. In this, even if non-intended members collude, they cannot extract any useful information from the transmitted messages. After the public group encryption key is extracted, both the computation overhead and the communication cost are independent of the group size. It is very strong security against collusion, constant overhead, and also our protocol is
