Data were collected from selected sample of 130 condominium households drawn from the study population using combination of systematic and simple random sampling technique, and analyzed using descriptive statistics and SPSS 22.0 .as well as data gathered though interview and focus group were analyzed in qualitative approach .the study finding revealed that, the low income group of Adama City residents couldn't afford condominium houses due to high price of condominium houses. The study shows that there is no communal housing for condominium house hold residents. For these reason they are in challenge especially during holly days and when they have a ceremony they didn't have place where they prepare something needed for ceremony or holly day. In addition the study reveals there was problem related to water supply and social life interaction, social life is poor people couldn't share whether it is happiness' or not. The culture of helping each other is under question. As the finding indicates majority of condo owners own the house without registration and lottery methods or procedures, either by city administration decision or buying from the first owner.

Exploitation, molestation and sexual harassment of women, especially in public work place continue despite or government"s daily sermons against it. Though the constitution of India guarantees justice, liberty and equality to all citizens and prohibits discrimination on the ground of caste, creed, race sex, place of birth, the status of women in the society is not what it should be. Sexual harassment at the workplace is not a new thing. Sixty percent or working women has faced sexual harassment at some point of time in their working lives. For every women who raises an outcry. There are hundreds if others, who suffer in silence, quit their jobs or get transfers. For years, sexual harassment was considered and inescapable part of working women"s life. Now awareness is slowly rising that no women should meekly accept sexual harassment as part of her lot. Women should also make use of various remedies open to them. To enable women to take advantages of these, it is necessary to provide for appropriate and adequate aid and advice and to make them more aware of such provisions. Special provisions must be made for this purpose by the state government under the legal services atrocities act, supplemented by what social action group and voluntary organization"s can do. One of the main thrusts of these activities must be enable women to get organized, this will help them to become to self reliant and confident. The supreme court, in the absence of any enacted law to provide for effective enforcement of basic human rights of gender equality, and the supreme court issued more guidelines and norms against sexual harassment at work place.

The present study initiated by the mining company Boss Mining injoint venture with Gécamines. the minerals of Cellular and Individuals Cobalt Silicates 'PCS' shifting to Cobalt poor ores the study is about the tests ofvaluation of this deposit containing approximately 1.3% copper and 0.7% cobalt, the optimization of heap leaching of this conventional ore already operational and Solvent extraction of Copper and Cobalt from PLS (Pignan Leach Solution) prepared laboratory experiments have shown that the copper content is leaching with dissolution yields of about 70% irrespective of the acidic medium used,however, Cobalt partially leaches at about 17% when using the acid only. Cobalt is leached with good yields (greater than 95%) by adding in the reaction medium a chemical agent such as sodium metabisulfite which facilitates the reduction of trivalent cobalt. Heap leach tests have shown that the leaching takes place with slow kinetics compared to stirred tank leaching and that the dissolution rate of metals could be increased by playing on the percolation rate. To promote subsequent solvent extraction operations Copper and cobalt, percolations with recirculation of PLS were conducted at an optimal pH of extraction of copper by the LIX 984N and the recirculation was carried out until PLS containing 4 to 5 g / l Cu and about 2 g / l Co. are obtained,extraction tests indicated as in most literatures and as observed in some factories of the place that Copper s extracts easily and selectively using the LIX 984N. The residual concentration of copper in the refining is less than 100ppm. On the other hand, to extract the Cobalt, whatever the type of exterminator used (D2EHPA, CYANEX 272 or LIX 272), it is necessary to raise the pH around 5. At this pH is observed precipitation of some metals (iron, Cu), which requires prior to their elimination. These experimental findings demonstrate the possibility to valorize the minerals of the Mukondo deposit using the techniques Combining ore leaching and solvent extraction of copper and copper Cobalt.
