Proximal Tubule Loop of Henle Distal Tubule Collecting Duct In the Nephron Cortex: †¢ Blood flows from the renal artery into the afferent arteriole †¢ Blood enters the capillaries of the glomerulus where blood pressure forces filtrate into the lumen of the Bowman’s capsule (filtrate consists of salts, glucose, and other small molecules – no blood cells or plasma proteins as they are too large to filter through the capillaries) †¢ In the proximal tubule: From the Bowman’s capsule, filtrate passes through the Proximal tubule where Na+ (which results in passive transport of Cl- ions in the form of NaCl), K+, glucose, amino acids, bicarbonate buffer and other nutrients are absorbed into the interstitial fluid and transported through the peritubular capillaries (water follows via osmosis as the interstitial fluid becomes hyperosmotic to the filtrate) Also the site of waste filtration (like processed drugs from the liver) via nonselective filtration from the interstitial fluid and surrounding tissues This is also the site of pH regulation of body fluids as transport epithelium secrete H+ and buffering NH3 to form ammonium ions (NH4+) In the Medulla: †¢ Loop of Henle 1) Filtrate enters the Loop of Henle from the Proximal Tubule 2) Descending Limb carries it down into the Medulla. . Descending Limb is semi-permeable. Water may pass through but ions may not. . Medulla has high osmolarity, causing water to pass from the Loop of Henle into the Medulla. 3) Ascending Limb carries filtrate back up from the Medulla . Ascending Limb is not permeable to water . Dissolved ions are actively transported from the filtrate into the Medulla, increasing its osmolarity. 1) Blood travels through the Vasa Recta in the opposite direction of filtrate in the Loop of Henle. 2) As blood travels down into the medulla, it absorbs some of the ions transported from the Ascending Limb, increasing osmolarity. 3) When blood flows back out of the medulla al ongside the Descending Limb, water is reabsorbed from the Medulla, maintaining its high osmolarity. III. Summary 1) Both the Loop of Henle and the Vasa Recta are countercurrent multipliers that act to conserve water. 2) About 90% of the water in the filtrate is reabsorbed into the bloodstream by the time it reaches the Distal Tubule. Back to the Nephron Cortex: †¢ In the Distal tubule: Much like the proximal tubule but primarily focused on NaCl reabsorption and K+ secretion into the filtrate pH regulation via reabsorption of bicarbonate and secretion of H+ ions into the filtrate Collecting Duct: †¢ The collecting duct then carries filtrate into the renal pelvis †¢ Site of urine concentration / dilution When kidneys are conserving water, surrounding interstitial fluid is hyperosmotic to the filtrate, thus aquaporin allow water to pass through the walls of the duct into the interstitial fluid 4 BIO 102-BioJeopardy II Exam is February 27th When kidneys are expelling water, surrounding interstitial fluid is hypoosmotic to the filtrate, thus kidney reabsorbs salts into the interstitial fluid without letting water follow MisMash 100-1.

Wheatstone Bridge essays

Wheatstone Bridge essays The most accurate measurements of resistance are made with a galvanometer (or a voltmeter) in a circuit called a Wheatstone bridge, named after the British physicist Charles Wheatstone. This circuit consists of three known resistances and an unknown resistance connected in a diamond pattern. A DC voltage is connected across two opposite points of the diamond, and a galvanometer is bridged across the other two points. When all four of the resistances bear a fixed relationship to each other, the currents flowing through the two arms of the circuit will be equal, and no current will flow through the galvanometer. By varying the value of one of the known resistances, the bridge can be made to balance for any value of unknown resistance, which can then be calculated from the values of the other resistors. In theory, if one arm of an originally balanced equal-arm Wheatstone Bridge is changed from R to R + R, the bridge voltage will be given by: V0 = (Vs/4) x (R/R) = (Vs/4R) x R Therefore, when plotting the graph V0 against R, the values R around less than about 10Ù we would expect a linear slope. For the larger values we will get a definite curve. In this experiment we will use the same technique to analyse and determine the out-of-balance voltage due to the change in resistance. The out-of-balance voltage is a measure of the change in resistance, which is thus made to be proportional to the external influence. Similar bridges, substituting known inductances and known capacitances for the resistance arms of the bridge, are employed in the measurement of the inductance and capacitance of circuit components. Bridges of this type are usually known as AC bridges, because AC sources are used rather than DC sources. To observe features of the out-of-balance voltage of an initially balanced Wheatstone Bridge.

Field Trip Reflection ( Cruise) Essay Example | Topics and Well Written Essays - 1000 words

Field Trip Reflection ( Cruise) - Essay Example It is a fascination to me because ships were normally just normally used to transport goods and people and it was not that fun. Now, cruise ships such as Grandeur of the Seas made it fun and vacation-like with the integration of a lot of amenities that make the passengers enjoy the ride for days if not weeks. What is more fascinating is that the cruise ship has to live with the supplies it has on board during its trip because obviously, it cannot resupply while it is in the middle of the ocean. Much more, when it has entertainment facilities that resembles the one we can find in hotels and bars. I can only imagine the planning involved to determine the resources needed that it could not bring so much logistics as it would weigh too much on the ship nor can it be so little that there would be little or scant resources to be had for the ship to operate and become fun. I can only imagine the coordination between its massive numbers of personnel to create an atmosphere that is convenient and enjoyable for the passenger. Thus during the visit, I made sure that I would be able to talk to some of its crew and know more about the ship and its operation to satisfy my curiosity. I spoke first with Tony, the Hotel Manager because I am awed with how he managed to operate a hotel in a middle of an ocean with all bells and whistles of a hotel in lands. If operating a hotel in land is already tough, moreso when one is in the middle of an ocean. Tony agreed that it is tough to operate a cruise but nevertheless, it is doable for their passengers to have an unforgettable stay during their ride at the Grandeur of the Seas. Tony is confident that they could deliver excellent service and unforgettable experience to their passengers because he had 15 years of experience behind him. He basically knows every nuts and bolts about the service operation of a cruise ship. Tony is also responsible for the service operation of the cruise and all employees report to him about the service ope ration. And this could mean a 24 hour operation so literally, he is on duty 24 hours a day. Tony agreed but it does not mean that he is working 24 hours. He is able to create a system that the operation will continue even if he is not around to rest/sleep or attend to personal needs. But still, he is on call for any issue that may arise about service operation during the duration of cruise. He stays four months on board the ship and has a vacation of two months. Of course along with the hotel like amenities of a cruise ship is its entertainment. So we also met Ricky who is responsible of the entertainment on the cruise. He is basically responsible for all the bands, singers, dances, music and fun happening on the ship. We also met the chef and he took us on a tour around the food operation facilities and the restaurant rooms. They have three different restaurants beside the main serving room which can hold 2200 people at the same time. They

NASA Strategic Plan Case Study Example | Topics and Well Written Essays - 750 words

NASA Strategic Plan - Case Study Example For a strategic plan to be achievable, it has to be clear such that one can easily understand what it is all about. NASA’s 2011 strategic plan lacks any form of clarity. There are no specific goals and objectives and one would argue that it is just a list of a few nonspecific and unformulated ideas. In addition, the mission statement for the company should be for specifically aimed at the employees, the customers, the stakeholders and partners to the organization. It should be short and clear-cut provided the message is passed understood by recipients. The vision statement should be a bit longer and detailed as this is gives the employees, stakeholders, and customers and partners an idea of what the company is working towards and the means through which it hopes to get there. In NASA’s strategic plan, the vision statement is short and rather vague while the mission statement is a bit more detailed than should be the case. In addition, the mission statement does not express a particularly unique mission that is unique to the agency. Both of the mission and the vision statement could probably apply to any government agency that deals in research and development as there is no mention of aeronautics or space. This could in away lead to a misunderstanding of the agencyâ€⠄¢s general tactical direction (National Research Council, 2012). A strategic plan for any organization should involve all the members of the organization, at every organizational level. This insinuates that all the members of the organization should be able to understand the plan for them to be capable of playing part in the attainment of the organizations goals and objectives. When setting goals and objectives, one has to involve everyone at every level in the organization, as they will all be helpful in working towards the realization of the company’s mission. Secondly, the strategic plans for NASA are a bit far stretched considering the

Malaysia Is A Fast Developing Country Environmental Sciences Essay

Malaysia Is A Fast Developing Country Environmental Sciences Essay Malaysia is a fast developing country that its change from an agro-based to an industrial nation, has led to an increase in the population. Malaysias population increased rapidly from 6 278 800 in 1957 to an estimated 29,179,952 in July 2012. Thus, the amount of solid wastes generated in Malaysia also increases rapidly. Statistic shows that on average, each Malaysian produces 0.8 kg to 1.2 kg of wastes per day (The Star, 2009). About 23,000 tonnes of wastes are produced each day in Malaysia. However, this amount is expected to rise to 30,000 tonnes by the year 2020 (Global Environmental Centre, 2008). The amount of wastes generated continues to increase due to the increasing population and development. Problem Statement There are different alternatives to reduce, treat and dispose the solid wastes. However, landfill is still the most common practice for solid waste management. Sanitary landfill for solid waste management is defined as an engineered method of disposing of solid wastes on land by spreading them in thin layers, compacting them to the smallest practical volume, and covering them with soil each working day in a manner that protects the environment (Brunner and Keller, 1972). There are 230 official dumping sites in Malaysia, the majority of which are crude landfills, with only 10% providing leachate treatment ponds and gas ventilation systems and with most having no control mechanism and supervision. However, the landfill method causes generation of leachate (Galbrand, 2003). Leachate is defined as a liquid that has percolated through solid waste and has extracted dissolved or suspended materials (EEA, 2005). Leachate occurrence is by far the most significant threat to ground water. Once it reaches the bottom of the landfill or an impermeable layer within the landfill, leachate either travels laterally to a point where it discharges to the groundà ¢Ã¢â€š ¬Ã¢â€ž ¢s surface as a seep, or it will move through the base of the landfill and into the subsurface formations (El-Fadel et al., 1997). Depending upon the nature of these formations and in the absence of a leachate collection system, leachate has reportedly been associated with the contamination of aqu ifers underlying landfills which resulted in extensive investigations for the past four decades (Albaiges et al., 1986; Mann and Schmadeke, 1986). Leachate contains high concentration of organic matter, inorganic matter (sodium chloride and carbonate salt) and heavy metal (Trebouet et al., 2001). Organic matter in leachate results in decomposition by microorganisms and causes oxygen depletion in surface water bodies (Schwartz, 2005). This favours anaerobic conditions which are detrimental to the aquatic life. The anaerobic micro flora is responsible for putrefactive processes which are characterized by the production of different types of toxic and noxious compounds (ammonia, hydrogen sulfide and phosphine) as final products of the organic matter degradation. Oxygen deficiency and toxic substance from anaerobic metabolism cause fish death and impairment of aquatic life. Therefore, since leachate can affect aquatic ecosystems and human health, proper leachate treatment is needed befo re leachate is discharged into receiving water (Paredes, 2003). Nutrients such as nitrate, ammonia and phosphate (along with co-contaminants such as pathogens, chemicals, and animal pharmaceuticals) are also found in leachate. High levels of nitrate, phosphate and ammonia in our lakes, rivers, streams, and drinking water sources cause the degradation of these water bodies and harm fish, wildlife, and human health. For example, at levels above 10 mg/L maximum contaminant level (MCL) in ground water, nitrates can cause human health effects, such as blue baby syndrome to pregnant woman. The current conventional leachate treatment systems are physical-chemical treatment, recirculation of leachate through landfill and biological treatment (El-Gendy, 2003). Physical-chemical treatment includes chemical precipitation, chemical oxidation, ion exchange and reverse osmosis, activated carbon adsorption and ammonia stripping (Ehrig, 1989). Precipitation in physical-chemical treatment is based on the addition of any chemicals to remove suspended solids, nitrogen, phosphorus, ammonia and metal. The physical-chemical treatment processes can produce high quality effluents, adapt to wide variations in flow and chemical composition and have the ability to remove toxic substances from leachate (Shams-Khorzani et al., 1994). However, these treatment systems are difficult to operate and require highly skilled labor besides high capital and operating costs. Some of these processes even require extensive pretreatment process (Britz, 1995). As a conclusion, the conventional treatment sy stems are effective in treating leachate. However, they require highly skilled labour and involve both high capital and operating cost. Therefore, constructed wetland was developed as an alternative to treat leachate in this research since constructed wetland has low cost of construction and maintenance (El-Gendy, 2003). The type of wetland used in this study is a combined system of subsurface flow (SS) and free water surface (FWS) constructed wetland. 1.3 Objectives The main objectives of this study are; To determine the nutrients (phosphate, nitrate and ammonia) removal from landfill leachate using combined subsurface and free water surface flow in constructed wetland between planted and control (without plant) system. To determine the nutrients removal in different hydraulic loading rate (HLR). To compare the percentage removal between subsurface (SS) and free water surface (FWS) in both planted and control system. To determine the uptake of nutrients by plants, Limnocharis flava in the subsurface (SS) and Eichhornia crassipes in free water surface (FWS). 1.4 Scope of Study The scope of this study is leachate treatment by setting up of lab-scaled wetland. The leachate was collected from landfill in Padang Siding and initial concentration of phosphate, nitrate and ammonia were analysed. Then, experiments were conducted with 25% leachate concentration diluted with water in a 60 L container being treated in two different planted and control reactors. Initially, Limnocharis flava plants were planted in the subsurface (SS) tank and Eichhornia crassipes was placed in the free water surface (FWS) tank in planted reactor and left for a few days for acclimatization process while no plant was placed in control reactor. The experiments were conducted with two different hydraulic loading rates which were high hydraulic loading rate (0.55 m/d) and low hydraulic loading rate (0.39 m/d). The efficiency of nutrients removal in leachate was evaluated by few parameters which were phosphate, nitrate and ammonia. The uptake of nutrients by plants in leaf, stem and root was also analysed as well as monitoring the physical plant growth in terms of physical appearance throughout the experiments. 1.5 Importance of Study The research was conducted to evaluate the efficiency of nutrient removal from landfill leachate in a combined system of subsurface and free water surface constructed wetland as well as to determine the nutrient uptake by plants. This nutrients removal was done by phytoremediation process by plants. Phytoremediation is the use of plants to clean up or control many kinds of pollutants including metals, pesticides and oil (McCutcheon, 2008). Phytoremediation is a potential method to treat leachate naturally in low cost. It is an environmentally friendly approach to remove pollutants from leachate. Therefore, phytoremediation can be practically used in landfill sites as constructed wetland to remove nutrients from landfill leachate. The plants used in constructed wetland can be Limnocharis flava in the subsurface and Eichhornia crassipes in free water surface. This research was also conducted to determine the most efficient loading rate for the leachate flow in constructed wetland in removing nutrients effectively. The loading rate plays an important role since the leachate flow also determines the uptake of nutrients by the plants. This research was also conducted to determine the ability of plants, Limnocharis flava and Eichhornia crassipes to uptake nutrients from the leachate.

Puzzle of King Tuts Inner-Coffin as Recreational Activity :: King Tutankhamun History Essays

Puzzle of King Tut's Inner-Coffin as Recreational Activity The King Tutankhamun jigsaw puzzle consists of 1000 individual, cardboard pieces which fit perfectly together to form a 13.75 X 38.5 inch portrait of his inner-coffin. It serves a dual purpose, not only as a two-dimensional replica of King Tut's coffin, but also as a form of recreational activity. The fun lies in methodically assembling the pieces together to create a desired image. Its intended consumer ranges from kids to adults. The puzzle can be found in the gift section at the UCSD bookstore. The bookstore is located in the middle of a college campus, primarily dependent on the patronage of college students. As its name suggests, it mainly sells textbooks for college courses, as well as clothing, school supplies, and assorted gifts. While the puzzle functions as an entertaining diversion, the actual inner-coffin of King Tutankhamun served a much more significant role. The discovery of this historical artifact offers a glimpse into the lifestyle and beliefs of the Egyptians. The Egyptians were deeply religious people, incorporating religious ideology into their everyday life. They believed in an inner-spirit, called the ka, which persists long after a person's death. With this in mind, they went to great lengths to ensure that the ka of a departed king enjoyed a comfortable, luxurious after-life existence, as it was crucial to the well-being of the Egyptian state. So, when King Tutankhamun died in 1327 BC., they lavished his tomb with funerary decorations and expensive furnishings. They paid particular attention to the quality and extravagance of his inner-coffin, where his remains reposed. The marked difference in the function and significance of the jigsaw puzzle and King Tut's actual coffin is reflected in the monetary value placed on each item. The inner-coffin is made of several hundred pounds of solid gold which theoretically reproduced the bodily and facial features of King Tutankhamun. However, the level of accuracy to which it was done is not known. Colored enamel and semi-precious gemstones decorate its surface, as well as very finely incised linear designs and hieroglyphic inscriptions. The king is depicted as holding a crook and a flail, both symbols closely associated with Osiris, the god of the dead. Taken together with the coffin's historical significance, it is worth several million dollars. While the average consumer may not have the purchasing power to afford such a luxury, he or she can trot over to the UCSD bookstore and buy a jigsaw puzzle depicting its likeness for a scant $11.
