Women's sexual control within conjugal union
This study attempts to examine the extent to which women have control over their sexuality within marriage and its implication for the spread of HIV/AIDS. The survey was carried out in metropolitan Lagos. The study shows that women have some control over their sexuality especially during certain occasions such as during menstruation, breastfeeding, pregnancy and when they are sick. However, only few women could negotiate with their husbands especially by insisting on safe sexual practices. The study therefore shows that women need to be educated on the need for safer sex practices, especially in this era of HIV/AIDS. They should also be economically empowered so as to practice safer sex. Again, men should be educated on the safer sex practices in other to control the spread of HIV/AIDS.conjugal, extramarital, menstruation, safe-sex, sex behavior, sexuality
EXAMINING THE IMPACT OF EXCHANGE RATE REGIMES ON INFLATION IN NIGERIA
This study empirically examining the impact of exchange rate regimes on inflation in Nigeria. Using quarterly secondary data, it was structured from 1981 to 1986 for fixed exchange rate and also 1987 to 2023 for managed flexible exchange rate. The variables used were Consumer price index (cpi) that captured inflation as dependent variable while Nominal exchange rate (nexrt), fixed and managed flexible exchange rate, and real gross domestic product (rgdp) as an independent variable. The variables were tested for the unit root test, both the ADF and PP unit root tests established that all the variables were stationary at both level (I(0)) for CPI and first differencing (I(1)) for nexrt and rgdp. The ARDL Bounds indicated test that there exists a long run relationship among the variables, they were co-integrated. The result of the open economy fixed exchange rate model shows that the co-efficient of output gap is -0.1146 and it was found to be statistically significant, it means that there is a trade-off between inflation and Unemployment during the fixed exchange rate regime while the result also showed that the managed flexible exchange rate regime is characterized by an output gap of 1.2920, which was found to be statistical insignificant, it means that there is absence of trade-off between inflation and unemployment during manage flexible exchange rate regime because a stronger positive relationship between inflation and unemployment may indicate stagflation pressure, where both inflation and unemployment rise simultaneously. In conclusion, managed flexible exchange rate regime is more impacted positively than fixed exchange rate regime. The study recommends that the Monetary authority should put more effort to control Nominal Exchange rate so that it would not cause inflation in Nigeria by supplying adequate US$ into Nigeria foreign exchange market when necessary

Development of an External Ultrasonic Sensor Technique to Measure Interface Conditions in Metal Rolling
Metal rolling is by friction which develops at metal-to-roll interfaces during the rolling process. But, friction at the metal-to-roll interface during the metal rolling process can cause roll surface damage if not controlled. Over time, friction results in downtime and repair of the mill. Therefore, lubrication is essential to control the metal-to-roll interface coefficient of friction. It is important to understand the conditions at the metal-to-roll interface to minimize energy loss and improve the strip surface finish.
In this work, a new method for measurement of metal-to-roll interface conditions, based on the reflection of ultrasound, is evaluated during the cold metal rolling operation. The method is a pitch-catch sensor layout arrangement. Here, a piezoelectric element generates an ultrasonic pulse which is transmitted to the metal-to-roll contact interface. This method is non-invasive to both roll and strip during the process.
The wave reflection from the metal-to-roll interface is received by a second transducer. The amplitude of the reflected waves is processed in the frequency domain. The reflection coefficient values are used to study the metal-to-roll interface conditions at different rolling parameters like, roll speeds and rolling loads. The results show that the reflection coefficient increases with increasing roll speed. This is because of reduction in the roll-bite contact area or increase in the frictional resistance of interface during the roll speed increment. However, the reflection coefficient decreases with increasing rolling load due to either increase in the roll-bite contact area or pressure.
The reflection coefficient determines the oil film thickness formation at the metal-to-roll interface. In-addition, the Time-of-Flight of the reflected wave obtained from this technique is used to estimate strip thickness and roll-bite length during the rolling process. The oil film thickness in the range of 1.25µm to 3.05µm was measured during the rolling process. The film thickness increases with increasing roll speed and reduces with increasing rolling load. The roll-bite value of 5.5mm was measured during the process.
The results from this study show that this ultrasonic technique can measure the metal-to-roll interface conditions (roll-bite, oil film and strip thickness) during the rolling process. This ultrasonic technique has the advantage of minor roll modification. Additionally, the experimental roll condition values obtained from the ultrasonic reflection method agree with theoretical values. The technique shows promising results as a research tool, and with further development, could be used for lubricant monitoring. Also, it can be utilized in the control system of a working mill for reduction of friction losses in the metal rolling process
Experiences of foreign entrepreneurs in Vaasa region
Entrepreneurship has been the most available means for economical and social survival for foreigners who are faced with different challenges in a new geographical location; in-spite of these challenges, the numbers of foreigners migrating to Finland is on the increase. This project examines the determinants factors which are responsible for motivating foreigners to becoming entrepreneurs and as well as factors that determines the success or failure of business start-up. The understanding of external, internal and motivational factors, barriers facing small business in all entrepreneurship stages and assistance or advices available to foreign entrepreneurs is very important and plays crucial role.
This project is aiming at exploring the experiences of successful foreign entrepreneurs in determining factors that are responsible for their motivation and successful business operation in Vaasa region of Finland. Seven successful foreign-entrepreneurs were chosen as sampling size from which data were collected by interview and observation. The result analysis shows that most foreign entrepreneurs were pull into entrepreneurship by their background and few were push as a result of economic disadvantages. And most of the barriers facing business start-up can be overcome by acquiring basic style skill such as knowing, planning and cognitive skill.Yrittäjyys on tarjonnut maahanmuuttajille eniten keinoja taloudelliseen ja sosiaaliseen selviytymiseen tilanteessa, jossa he ovat törmänneet erilaisiin haasteisiin uudessa maantieteellisessä sijainnissaan. Näistä haasteista huolimatta Suomeen muuttavien ulkomaalaisten määrä on kasvussa. Tässä työssä tutkitaan niitä vaikuttimia, jotka motivoivat maahanmuuttajia ryhtymään yrittäjiksi, sekä niitä tekijöitä, jotka ratkaisevat uuden yrityksen menestymisen tai epäonnistumisen. Sisäisten, ulkoisten ja motivationaalisten tekijöiden, sekä pientä yritystä sen eri vaiheissa kohtaavien esteiden ymmärtäminen on tärkeää. Samoin maahanmuuttajille tarjottava apu ja neuvot ovat tärkeässä roolissa. Tässä työssä pyritään tutkimaan Vaasan seudulla menestyneiden maahanmuuttajayrittäjien kokemuksia määrittelemällä ne ratkaisevat tekijät, jotka ovat heidän motivaationsa sekä menestyksellisen yrittäjyyden takana. Otokseksi valittiin seitsemän menestyvää maahanmuuttajayrittäjää, joita haastattelemalla ja tarkkailemalla tutkimusdata kerättiin. Analyysin tuloksena voidaan todeta, että suurempi osa yrittäjistä ryhtyi yrittäjäksi taustansa perusteella, ja pienempi osa pakon sanelemana taloudellisista syistä. Suurin osa uutta yritystä kohtaavista haasteista voidaan voittaa yrittäjän päättäväisyydellä, joten sisäiset tekijät vaikuttavat menestykseen enemmän kuin ulkoiset. Menestyvät maahanmuuttajayrittäjät hallitsevat myös hyvin monet perustaidot, kuten tietotaidon, suunnittelutaidon ja kognitiivisen ajattelun taidon
Nigerian Government's Attempts at Removing Fuel Subsidy and the Attendant Mass Protests
The Federal Government of Nigeria made several unsuccessful attempts at stopping petrol subsidy by arguing that the policy is unsustainable. Seven unsuccessful attempts were made between 1999, when the country returned to democratic rule, and 2012. Though the government might have good reasons for removing petrol subsidy, it was clear that there was an obvious disconnection between the government and the people as the people were not in support of the policy. This chapter examined coverage of petrol subsidy removal by three national dailies. Content analysis was adopted as the research method. It was discovered that 49.4% of the stories published by the selected newspapers in the study period were not in favour of petrol subsidy removal. It was therefore recommended that government should endeavour to carry Nigerian citizens along ever before introducing such kind of policy and that media practitioners should set an agenda for fighting corruption in the oil industry.</jats:p
