The Burning Of Biomass And The Resulting Emissions

national borders. The burning of biomass and the resulting emissions are contributing to global climate change. In particular, the incomplete and inefficient combustion by traditional cook stoves releases greenhouse gases including carbon monoxide, nitrous oxide, and methane into the atmosphere (Kees and Lisa, 2011). Meanwhile, other organic compounds and particulate matter from biomass combustion contribute to local and regional air pollution. Developing nations have sought to escape environmental ruin through the expanded use of energy efficient and renewable technologies. Ethiopia’s renewable energy potential is considerable, with abundant biomass efficiency, biogas, solar, hydropower, wind, and geothermal possibilities available (Forum†¦show more content†¦2.1.6.

Modern electricity generating grid connected wind turbines constitute a promising technology, to supplement hydropower, especially because the correlation of wind resource and hydrology availability is very good (EREDPC, 2007). 2.2. Wind energy resource potential in Ethiopia The total wind resource of Ethiopia is estimated to be 20.064 TJ/year; however, a significant amount of it had not been used yet throughout the country (Ramayya et al., 2007). As the study of Woldeghiorgis Weldesenbet (1988) there are few promising windy areas in Ethiopian located alongside the main East African Rift Valley, the Northern Eastern escarpment of the country near Tigray regional state, the Southern part of Ethiopia near the Kenyan boarder, the central and eastern part of Ethiopian specially south east of the Somalia region.

King Tut s Death Mask And The Statues Of Rameses

Once towering, but now slowly crumbling pyramids grace the horizon, bejeweled and dusty royal mummies lay buried and forgotten by the sands of time, and mysterious and often strangely heroic murals intertwined with a scattering of hieroglyphics sprawl across the walls of tombs and temples alike. These are the only evidence left of a once vast empire that is rapidly falling into disrepair as its already decrepit state grows worse. However, the current state of ancient Egypt does not curb the curiosity of adventure seekers looking to peek into a diminished era; today, a multitude of onlookers wander through the glorious yet now empty tombs that once held ancient Egypt’s elite. Millions more in museums around the world peer through the glass enclosing the precious jewels, fragmented pottery and statues, and frayed and often threadbare garments that before adorned peasant and monarch alike. Nevertheless, it is the fascinating intricacies and myths surrounding pieces such as King T ut’s death mask and the statues of Rameses the Great that still grip one with awe and leave lingering unanswered questions behind. What was Egypt like during the reign of each of these age-old monarchs? Even more so, what traits and morals did each hold that wove legacies characterized with such vivid larger than life personas of each, yet above all else, how could one pharaoh inscribe his story in our hearts as to ensure an enduring image even after his death?

Facultative Mutualism free essay sample

All around me casual conversation abounds, but I am too distracted to take part in it. Instead my eyes are trained on the white sheet of paper in front of me. I glance up for a moment to see a sea of desks topped with papers identical to my own. The teacher circles back to the front of the room, having finished her task, immediately commanding my attention. â€Å"Take the rest of class to discuss your answers with your neighbor,† she says to the class before returning to her desk. I continue to silently stare at the face-down paper in front of me until someone nudges me. I look over to see a face similar to my own staring back at me, that of my twin sister Raven. â€Å"Are you going to look at what you got any time soon?† she inquires, flashing her characteristic smirk. â€Å"I will as soon as you do,† I simply reply. We will write a custom essay sample on Facultative Mutualism or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page â€Å"On three then,† she counters. We count together, â€Å"one†¦.two†¦.three!† I suck in a deep breath, as if I am about to plunge into the deepest ocean, and flip the paper over. 97. Victory seems within reach.; â€Å"How did you do?† I innocently inquire. She checks my grade first before replying â€Å"Well, I got two more points than you did so if the math isn’t too complicated for you it comes out to 99.† I shrug off her insult by responding, â€Å"Yeah well I beat you by three points last week.† The bell cuts our quarrel short as we exit Mrs. Cocchi’s Pre-Calculus classroom. For as long as I can remember, Raven and I have been in constant competition. When she received the Spanish Subject Mastery award I worked to earn the French Subject Mastery award and when I obtained the Wellesley Book Award she countered with the honorable Harvard Book Award. My competition with her is a major factor in my academic success, and I often wonder if I depend too much on her. Without her, would I have spent that extra hour studying or revising my papers? I ultimately decided that our relationship is best described as facultative mutualism – a symbiotic relationship in which two organisms benefit from their interaction with one other, but neither requires it to survive. I now believe that both of us can easily excel in our classes without the other. However, our competition has encouraged us to push our limits and better ourselves in ways that we could not have accomplished alone. As we get ready to depart for college and set off on separate paths, old insecurities wash away with the tide. I know that I can thrive in the college atmosphere without being in the same classes as Raven. All I need to do is remember our relationship: facultative mutualism. We both know the other will never settle for second best, and will be putting in the same effort to ensure the fruition of our goals. One thing is for sure, the first thing I will do after every exam is call Raven up and, on the count of three, we will compare scores. When that time comes, I count on being the one with the smirk on my face.

Issues and Ideas of Polygamy by Aisha B. Lemu free essay sample

Issues and ideas of Polygamy by Aisha B. Lemu In the essay of Defense of Polygamy by the british, feminist, activist and writer Aisha B. Lemu, explains why polygamy could be a great solution for many women without partners or for many women with partners but with difficulties in their relations. She explain why because of the large numbers of men dying in war, and others violent confrontation groups, a huge group of widows, fiances, and women in general, have left alone without any protection for themselves or their children. The quantities in general of men in these days are low and have left a large group of women alone with no or difficult chances to get married or have a partner. ?Therefore, she states that most of women rather believe in sharing a man that not having any at all. And even more if the political laws of the country establish an obligation toward the second, third or fourth wife and their respective children, making a responsible way of supporting the rights of the woman. We will write a custom essay sample on Issues and Ideas of Polygamy by Aisha B. Lemu or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For me this first demonstration makes a logical reason, but not the answer for a truly right solution. I dont think polygamy is the true unique solution for the uniformity of our era. I think the true problem here is the violence and misunderstanding that we had made with each other and that has lead us to unnecessary wars and undesirable misbalance of the masses of the gender. Not attacking the real problem but rather settling ourselves to the problem, content to leave the wrong things we have done as they are and conforming to live with it. It’s like the problem of deforestation; we know that the problem is there but we dont resolve it, we prefer to put on oxygen masks in the future than to attack the real problem now. So then I believe that her reason of polygamy because of the war issue is not a true solution but a momentary accordance to survival, not attacking or giving a real answer (which is to me the increase of violence of everyday that has made us left with a sex misbalance). But it doesnt end there, a big question is about to expose, at it is What will happen then in the future or into a few more years where the disorder of sexes will may be so dramatic that for every man twelve women will be shared? Then what? Polygamy will maybe not be a truth solution and then maybe we will have to attack the true problems of violence and deaths of men. Another point that the author exposed is the circumstances where the wives are sick and the husbands cant manage it or where wives are unable to have children while the husband very much wants them. This argument represents a more logical thought, although not entirely correct in my opinion and own personal believes. I just cant still understand why it is necessary to go get another partner just for the benefit of a baby, when you could solve it renting a belly without resorting to commitments with other woman. But even if it happens or not, I think that the choices of a couple are personal choices and if the wife agrees then is her own personal choice. ? The other point that exposes is the cases where a marriage has not been very successful and the husband loves another woman. The author also express some things about when a husband need to divorce from the first wife to be with the second wife, but the first wife doesnt want to be divorce for the secure of the marriage, for herself and their children. Before starting to explain anything else I do think is quite understandable the worry that a wife could have for the economical and physical securities that a man provides (especially on these countries were most of the woman depends economically in the husband), but for the secure of the marriage? What secure? Now, the author needs to explain this in more details, because if the concept of secure marriage is to cover up from the society the very truth status of a relationship because of the judgments that this could bring, then I have very poor understanding the meaning of the term marriage, it seems that this definition doesn’t involucrate then a covenant of love with a partner but a commitment with cultural society. Whatever of all the case is, we must keep in mind that it is obvious that we will some how disapprove these ideals and thoughts, at least, obvious, if you are part of that kind of cultures and believes. Each culture is different and the analysis that we give others incorporating it into our own is simply wrong and insignificant. We just cant measure the same cultures with the same tool; every culture it’s unique. And the differences that demonstrate each one of them with the others doesnt gave us the right to classify them as less or more. Having said that, it was obvious that my answers were not going to be that much of acceptable. References Aisha B.
