Culture, Beliefs, Attitude and Peer Group Influence on Female Genital Mutilation in Southeast Nigeria

Background: Female Genital Mutilation is still practiced in Ebonyi State in Southeast Nigeria, despite the complications that follows it and government legislation against the practice. Aim: To determine the impact of Culture, Beliefs, attitude and Peer Group Influence on the persistence Female Genital Mutilation practice in the State especially in the rural areas. Materials and Methods: Qualitative study that used Focused Group Discussion and In-depth interviews for data collection. Those willing and given consent were recruited into the group discussion according to age, marital status, educational level and their location in the state. In-depth interviews were used with the Stake Holders, Opinion Leaders, Traditional Rulers and the Clergy. Result: A total of 454 participants were recruited from the 13 local government areas of Ebonyi State but only 420 (92.5%) participated. The age ranges of participants were 25 to 35 years for single males and females while the married participants male and female were aged 35 to 70 years. One hundred single females (23.8%) and 94 single males (21.4%) participated while 97 (23.1%) married women and 95 (22.6%) married men participated. Out of the 26 health workers recruited only 22 (5.2%) participated. Four traditional rulers, 4 women leaders, 4 youth leaders and 2 clergy 12 (2.9%) in number had in-depth interviews. All the participants had knowledge of FGM and its practice. Rural health workers are getting more involved. ‘Female Genital Crushing’ is replacing actual cutting. The participants all agreed there is no benefit and the practice should stop. Conclusion: Female Genital Mutilation is secretly practiced and is getting replaced by “Female Genital Crushing” perpetrated by rural health workers as well as mothers, fathers, traditional birth attendants and the peer group playing a major role with low knowledge of the Law against Female genital mutilation.

The Characteristics of Dielectric Barrier Discharge and its Influence on the Excimer XeCl Emission

In this work, the influence of discharge modes on the excimer XeCl emission (308 nm) has been studied by adding helium gas into the xenon and chlorine mixture. It is found that the transition from filament discharge to glow /filament - combined discharge leads to the decrease in excimer emission. We are the first one to use a flowing water film as an outer transparent electrode, and achieve a higher UV intensity, compared with the case by using a metal mesh as the outer electrode. The influence of the gas temperature both in the reactor Tg and in a discharge channel Tc on the excimer emission has been analyzed preliminarily. Finally, it has been expected that the replacement of chlorine gas Cl2 by another chlorine gas may reduce the heat generated in the discharge processes and give rise to the excimer XeCl* radiation.

The Propagation of Inertia-Gravity Waves and Their Influence on Mean Zonal Flow, Part One: the Propagation of Inertia-Gravity Waves

Inertia-gravity waves play an increasingly important role in the middle atmosphere dynamics. As a result, more attention has been paid to the study of inertia-gravity waves, especially to the middle atmosphere gravity waves. This paper presents some aspects of inertia-gravity waves with emphasis on the propagation. Two methods are used here, namely, geometric optical method and physical optical method. We can see from the study that inertia-gravity waves are similar to planetary waves in some respects and they are different from planetary waves in others.

Branches of the Summer Asian Lower-Level Jet Stream and Its Influence on the Rain Belt in China

Based on the analysis of the Asian lower-level jet stream, this paper indicates that having shifted to the Bay of Bengal, this large-scale lower-level jet(LLJ) develops into two branches: the northern branch (NB) which is a strong southwest flow moving into the inland of China along the southeast side of the Qinghai-Xizang Plateau and then moving eastward to Japan along the north side of the subtropical high, and the southern branch (SB) which continues to be a west flow and travels into the West Pacific across the Indo-China Peninsula along the south side of the monsoon trough. Above the two branches are two synoptic-scale transient tubular monsoon circulation systems, the northern branch being a subtropical monsoon stream tube (SMST) and the southern branch a tropical monsoon stream tube (TMST). Their ascending branches, corresponding to a subtropical monsoon rain belt and a tropical monsoon rain belt respectively, bear considerable influence on the weather over China.

A Study of the Pesticide Fenthion: Toxicity, Mutagenicity, and Influence on Tissue Enzymes

In this paper results of acute toxicitv (oral and dermal), cumulative toxicitv, subchronic toxicitv. and conjunctiva irritation tests are reported. The mutagenic effects of fenthion. using SCE (in vivo) and UDS(in vitro) as indicators, were also tested. Histochemical changes in enzyme activities (including AChE. ATPase. and AK.P) in tissues were observed. The results showed that the acute toxicitv of fenthion belongs to highly toxic category. The highly cumulative effect of fenthion was also observed. The subchronic toxicitv test. however. did not reveal any abnormal effects except the inhibition of ChE activity in plasma. The dose and ChE activity relationship equation was V=0.82.x+4.71. The SCE and UDS tests revealed no mutagenic potential. In histochemical experiments we found that AChE activity in tissues was markediv inhibited. AKP and ATPase activities at the cortex rcnis were increased in the treated rats.(c) 1990 Academic Press. Inc.

Influence on the Lifetime of ^(87)Rb Bose-Einstein Condensation for Far-Detuning Single-Frequency Lasers with Different Phase Noises

We study the influence of the phase noises of far detuning single frequency lasers on the lifetime of Bose-Einstein condensation（BEC）of^（87）Rb in an optical dipole trap.As a comparison,we shine a continuous-wave singlefrequency Ti：sapphire laser,an external-cavity diode laser and a phase-locked diode laser on BEC.We measure the heating and lifetime of BEC in two different hyperfine states：｜F=2,m_F=2〉and｜F=1,m_F=1〉.Due to the narrow linewidth and small phase noise,the continuous-wave single-frequency Ti：sapphire laser has less influence on the lifetime of^（87）Rb BEC than the external-cavity diode laser.To reduce the phase noise of the external-cavity diode laser,we use an optical phase-locked loop for the external-cavity diode laser to be locked on a Ti：sapphire laser.The lifetime of BEC is increased when applfying the phase-Jocked diode laser in contrast with the external-cavity diode laser.

Nucleation of Cold Rolled FeCo Alloy during Annealing and Its Influence on the Formation of Recrystallization Texture

The orientation distribution of recrystallization grains formed during annealing, as well as their misorientation relationship to the deformation matrix in cold rolled FeCo alloy have been investigated. It was found that most of the recrystallization nuclei were located near the boundary area with rather random orientations, and their misorientation angles to the deformation matrix were generally very high. However a few nuclei were also observed inside the deformation grains, to which they had very similar orientations. Therefore the misorientation angles between the nuclei and the deformation matrix were generally very low. The orientation and the misorientation distributions of the nuclei have very strong influence on the recrystallization process which could result in a very weak recrystallization texture. The corresponding mechanism is discussed.

Comparison of two approaches for detecting the depth of edge influence on vegetation diversity in the arid valley of southwestern China

Three types of landscape boundary (forest/pepper field, forest/cabbage field,and forest/grassland) were selected in the arid valley of upper reaches of Minjiang River,southwestern China. On the basis of vegetation diversity, the depth of edge influence (DEI) ondifferent types of landscape boundaries was estimated using principal components analysis (PCA)method and moving split-window techniques (MSWT). The results showed that in the 5 transects, PCAmethod was able to detect the edge influence depth with 3 transects, while MSWT could explain 4transects. It is concluded that PCA and MSWT both can be used to detect the depth of edge influencewithin 50 m from the edge to the interior. Similar conclusions were drawn in the forest of eachtransect with the two methods, but no similar conclusions were drawn in the pepper field of eachtransect. Although the two methods have advantages and disadvantages respectively, they are usefultools for characterizing edge dynamics. Comparing the two methods, MSWT is more successful.

Study on Possible Mechanism of Terrain Influence on Cold-flow Snowstorm

[Objective] The research aimed to study the possible mechanism of terrain effect on cold-flow snowstorm.[Method] By using the meso-scale numerical model(WRF),a cold-flow snowstorm weather process in Shandong Peninsula was carried out numerical simulation and terrain sensitivity contrast test.The possible reason of terrain effect on falling zone and strength of snowstorm was deeply analyzed from water vapor,thermodynamic field and so on.[Result] The mountain terrain in Shandong Peninsula had great influences on falling zone and strength of cold-flow snowstorm.The strength of snowstorm obviously increased,and the snowfall center obviously moved northward.The main reason was that terrain caused the low-level wind field convergence and vertical movement in the troposphere strengthened.Then,the spatial distribution of water vapor and snow water content in the cold-flow snowstorm process obviously changed.So,the whole snowstorm process was affected.[Conclusion] The mountain terrain in Shandong Peninsula was the important element which needed to be focused on considering in the forecast analysis of cold-flow snowstorm weather process.

A Numerical Study of Mesoscale-Topography Influence on the Heavy Rainband of Typhoon Hato(2017)

During the movement of Typhoon Hato(2017)over land,heavy rainfall occurred when the spiral rainband which was about 100 km distance away from the center of the typhoon passed the Dayao Mountain(with an elevation of 1.2 km).In this study,the structures and forming mechanism of the heavy rainband along the mountain range are investigated by using high-resolution model simulations.The results show the importance of topography in causing the heavy rainband.Upslope of the steep terrain lifts the cyclonic flow to produce strong upward motion when the rainband passes across with high wind speed.At the same time,the warm and humid air is lifted to the steep slope,causing unstable energy to accumulate over the windward slope,which is conducive to the occurrence of rainfall.In particular,the convective cells generated upstream of rainband will further strengthen and develop due to the uplift when they move close to the mountain foot.Some precipitation particles in the convective cells fall to the ground while others move downstream with the intense updrafts,forming heavy rainfall near the summit.As a result,the largest accumulative rainfall coincides well with the orientation of the mountain ridge.

ON THE PREDICTION OF TROPICAL CYCLONE LANDFALL AND INFLUENCE ON SOUTHERN CHINA USING MONTHLY OLR ANOMALIES FOR PRIME SUMMER

With the OLR data, the landfall and activity of tropical cyclones (TC) in southern China over a 20-year period (1975～1994) are studied. The result shows that the variation of the monthly anomalous OLR is somewhat teleconnected with the TC activity in southern China. The former is used to predict short-term climate for the latter over months with frequent or no TC influence. To some extent, the relationship between the TC activity in southern China and the monthly mean OLR anomalies is dependent on the climatological location of the subtropical high in northwestern Pacific region.
