What Is a Filter Feeder

Filter feeders are animals that get their food by moving water through a structure that acts as a sieve. Stationary Filter Feeders Some filter feeders are sessile organisms - they dont move much, if at all. Examples of sessile filter feeders are tunicates (sea squirts), bivalves (e.g. mussels, oysters, scallops), and sponges.  Bivalves filter-feed by straining organic matter from the water using their gills. This is accomplished using cilia, which are thin filaments that beat to produce a current over water over the gills. Additional cilia remove the food. Free-Swimming Filter Feeders Some filter feeders are free-swimming organisms who filter the water while swimming or even actively pursue their prey. Examples of these filter feeders are basking sharks, whale sharks, and baleen whales. Basking sharks and whale sharks feed by swimming through the water with their mouths open. The water passes through their gills, and food is trapped by bristle-like gill rakers. Baleen whales feed either by skimming the water and trapping prey on the fringe-like hairs of their baleen or gulping in large quantities of water and prey and then forcing the water out, leaving prey trapped inside. A Prehistoric Filter Feeder One interesting-looking prehistoric filter feeder was Tamisiocaris borealis, a lobster-like animal that had bristled limbs that it may have used to trap its prey. This may have been the first free-swimming animal to filter feed. Filter Feeders and Water Quality Filter feeders can be important to the health of a water body. Filter feeders like mussels and oysters filter small particles and even toxins out of the water and improve water clarity. For example, oysters are important in filtering the water of the Chesapeake Bay. Oysters in the bay have declined due to overfishing and habitat destruction, so now it takes about one year for oysters to filter the water when it used to take about a week. Filter feeders can also indicate the health of water. For example, filter feeders like shellfish can be harvested and tested for toxins that could result in paralytic shellfish poisoning.

Climate Change Global Warming - 2802 Words

David Newell Climate Change Climate change has become one of the most crucial topics of discussion over the last 50 years. Its popularity, or rather infamousness, and lack of general consensus have caused it to be a subject that everyone knows, but few know well. Time may be running low, and with the effects being felt now more than ever, people are beginning to feel the need to make a real endeavor against global warming. Individual efforts are seemingly stronger and more widespread, but still it is not enough. The first move in battling global warming is to deliver the facts. Many questions vital to solving global warming are left unanswered, including whether there are even any valid reasons to take serious action, and if it were necessary to do something, how could we as a planet come together to make a difference? What would we have to do? Nearly everybody has an opinion and with extremists skewing information and misleading the public, the universal knowledge of the truthful causes and effects will be the greatest influence on a course of action. Once the facts are known, it is likely that the values and opinions of many will shift, and understanding will bring change to the public agenda. That’s how it has always worked before.

The Prodigal Son

Question: Select one Micro Script for this Essay Walser is often less concerned with recording the finished thought than with capturing the movement of a mind in the act of thinking; its the motion that stays with you, not a stable set of meanings. Answer: The Prodigal Son Abstract The short story being scribbled down with a pencil by Robert Walser talks about a weird man which he encounters on a day. He describes the day and base it over the prodigal man whom he saw once. It is evident from the fact that the opening consists of reference to this man. Once again I encountered the incomparably uncanny man, whom I consider a likeable, useful person. The narrator closely discusses about his opinion about the man whom he remarks as a person haunting nocturnal streets (Walser, 2010). I have a by no means unfavorable impression of this uncanny individual who haunts the nocturnal streets, I announce to you respectfully that I have now and then had occasion to see him standing before a shop window. The story talks about his behavior being a blend of good and bad and the author who is observing him closely across the street. His age was at an ironic stage being as old as a hill yet blossoming in the freshness of youth. He describes the man with such an inherent detail t hat poses up several questions about his appearance, his behavior, his attitude and his beliefs. Some of the evidences form the text are, This man of the world or pious manwhich neednt be such an incommensurabilitydoesnt believe in fatednesses, but now something entirely different has just occurred to me, namely the circumstance that imperious, dogmatic persons can just as suddenly turn into indulgent, docilely obliging ones. he maintains apparently excellent relations with distinguished house- holds and looks as though he were as old as the hills and in the bloom of youthas though he were constantly remaining the self- same immediate middle, the good fellow who isnt good, the bad one who isnt bad. The story then directs to the description of the prodigal son as described in the biblical context explaining about its nature and comparing with the ideal example. However, he also compares him with another figure named Saul who has no patience for emotionality (Walser, 2010) and is desc ribed in Old Testament. The writer goes on with describing the characteristics of Saul in some ironical contexts. He had highly engrossed love for music which also pierces his heart. He compares that uncanny man with the story of a prodigal son described in texts and hence claims that they are a bit unlucky yet try to be happy in such circumstances knowing about their fate and their future. This story basically questions about the feeling of being happy that contains both a strong and a shaky feeling (Bernofsky). Happiness in its own term is a feeling that has different meanings to different people. The uncanny man in its own is a story of intensive description of nature, attributes, behaviors and features of a prodigal son. This micro script from the book Microscript is a short description of a man who was observed by the author and was compared to the different personalities explained in biblical text of Old Testament. This short description beholds a lot of descriptive elements to paint an actual picture of all the personalities. This provides a short summary of the microscript.

Foundations of Research and Evidence Based Practice

Question: Discuss about the Foundations of Research and Evidence Based Practice. Answer: Introduction With the advancement in science and technologies the quality of human lives has been improved significantly and in current scenarios the human beings can easily do there requisite tasks without any hassle. As a result, the human has become lazy and avoid hard work and for reason the modern human tend to be unfit and prone to several diseases. Moreover, among the several dreadful diseases back pain is one of the vital diseases and most common in the modern public. There are many people, who suffer from chronic back pain and few of them usually not shows significant improvement with the regular therapies (Cashin Cook, 2011). Acupuncture is a traditional Chinese therapy, and it is heard that it has significant effect on several different acute diseases as well as for the pain it has substantial effect so that the research is on whether it is a worthwhile treatment for the patients with low back pain or not. Main body The impact that has been arisen currently depicts several stories and myth circulated all over the field of healthcare and wellbeing program, where the physicians and healthcare practitioners greatly discuss on this topic; on the effect of acupuncture on the human body. Acupuncture mainly deal with some important points in human body, those are liable for the functions of several different organ of human body. The chronic back is one of the worst back pain problems with depicting the signs of cancer in some cases. The acupuncture is the best instrument which is used for reducing the back pain and henceforth it is considered for the treatment. Acupuncture helps in the improvement of the digestion system in the body and thereby it helps to get relief from the back pain. For this reason the acupuncture is used for the treatment of chronic back pain. Moreover, according to the perceptions of the acupuncturists systematic pressure on the acupuncture point improve the body function effecti vely so that play important role in curing the patients, who suffers from several different types of acute diseases. In the current situation, there are several patients, who suffers from the acute back pain and the main cause of the disease is laziness of the modern people, with improving life style the human being has become lazy and need more luxury and these lead them into several diseases and back pain is one of them, which is most common in modern human beings. As a healthcare practitioner I have to face several cases, where the patients are suffering from acute back pain and the usual treatments have not any significant effect on them. It relieves them for the time beings but not cure them permanently. Therefore, the necessity of an alternative treatment is emerging and so that the reference of acupuncture therapy is coming as it is heavily discussed in healthcare field among the public related to healthcare such as the physicians, healthcare practitioners and patients (Krali k, Trowbridge, Smith, 2008). Moreover, it is widely discussed that it has no side effect on the human body and it has only positive effect on human body. Conclusion As, I have faced several patients who are suffering from acute back pain and I observed that the usual Allopathic treatments have not significant effect on the these patients as it provide short term relieves to the patients of acute back pain and the problem of the patients remain with them and the usual treatment cannot cure the back pain in permanent basis thus, I have to search for alternative treatment and so I choose acupuncture therapy. Part A, Section 2: Formulate a PICO In order to investigate the effect of the treatment on the patients, PICO is an effective instrument that helps in assessing the condition of the patients as well as the effect of the treatment on the patients. It is one of the most effective as well as popular tools among the people of nursing profession as it provide effective outcome that help in effectively evaluate the condition of the patients and the effect of the treatment on the patients (Polit Beck, 2012). For this undertaken matter a PICO is included and by the PICO the result and understanding will be generated that, whether acupuncture is effective in acute back pain or not. For this reason I have collected the response of the patients of acute back pain to the acupuncture therapy and their responses has been put into the popular and effective tool PICO. The results of PICO has been determined and evaluated about whether acupuncture is an effective intervention for chronic low back pain. In the research study, 58 participants have been selected for examining the effectiveness of acupuncture. Population The age of the participants is above 18 that will help to assess the diagnosis pattern including treatment and concordance within a clinical trial of acupuncture for the low back pain. Intervention In a controlled pragmatic randomized clinical trail, 58 patients with low back pain in between 4 weeks and 11 months duration were offered acupuncture randomly. Treatment and standardized diagnosis were completed by the practitioners. The diagnosis was based on low back pain syndromes. One of the practitionerss then re-examined the patients effectively. The inter rater reliability diagnostic was assessed in terms of congruent classifications. Comparison All groups were involved for comparison. The focus was on physical therapy rather than the structured exercise. Outcome The diagnosed syndrome that was most commonly associated with the low back pain was blood stagnation and Qi followed by Bi syndrome and kidney deficiency being more than one syndrome being determined for 66% of the patients. The practitioner has examined the patients concordance was reasonable which was between 80% and 47 of the classifications while values of Kappa lay between 0 and 0.67. The practitioner has provided 158 treatments in total using 188 different acupuncture methods. The most commonly channels used were gall bladder and bladder and the commonest point was BL-23 ad two points of Huatuojijaji. The practitioners have also used Auxiliary treatments to varying degrees. Therefore, Acupuncture is considered as the most effective treatment for low back pains. The diagnostic concordance among the practitioners was clear and reasonable themes emerged for the treatment. According to the result of PICO it is observed that the acupuncture therapy is effective in the treatment if the acute back pain as it significantly improves the condition of the patients and so that it provides much more relieves to the patients and its effects are for long term and permanent as it completely cure the diseases from the patients. Besides this, it is also observed that it has not any significant side effect on the patients. Therefore, the acupuncture is effective in acute back pain and it could be given to the patients of acute back pain. Part A, Section 3: Advance search in CINAHL The advanced search on the CINAHL is based on the search of the broader database which helps in the creation of focus on the PICO measurements that are taken for the consideration of the study of CINAHL in the context of full text. It includes the following criterias of the assessment that must be completed for the enhancement of the research process and thereby it provides the focus on the undertaken scenario taken for the study. The scenario that is taken for the study focuses on the chronic low back pain which is seemed to be improved with the help of the usage of acupuncture (C. Lawrence, 2016). The treatment is provided in the form of the literature with providing the symbols of the low back pain and thereby the strategies are focused for mitigating the disease low back pain. The CINAHL process of the research is conducted for the achievement of the good source with conducting qualitative process for the collection of the instrument used for curing the disease. With the consideration of the retrospective analysis, the investigation of the CINAHLs potential contribution is identified with the consideration of the research and thereby the studies are created by the unique database with the consideration of the CINAHL database up gradation and preparation. With the consideration of the 58 quantitative reviews, about 43 reviews are selected which thereby helps in the consideration of the successful study for the research. The 43 reviews are found to be ill and thereby the consideration of the study provides the final synthesis of the CINAHL database. With the consideration of the database, the reviews that are notified seemed to be 11 reviews with the identification of the study for the database and thereby the median helps in the identification of about 9.09 % while the lowest value is 5 % to the highest value is about 33% (Lawrence, 2007). The rigorous strategies are included for the acute collection of the index regarding the case scenario and thereby the limited number of reviews is created with the creation of systematic reviews. The CINAHL process provides the step by step process with the creation of enhancement of the study of the scenario mentioned. The instruction provides the appropriate approach for the enhancement of the acupuncture which is used for the chronic low back pain. It provides the approaches that must be covered in the part of the Medline and thereby the focus is created for the development of the database. The CINAHL database provides the appropriate approaches with the conducted research that consists of the process of CINAHL which includes the Embase, Medline and the Database formation of the diseases with the preferred treatments. The studies that are included helps in the consideration of the criteria of PICO which are as follows:- Consideration of the individuals with the CLBP defined with the time duration of 12 weeks or longer. Prescribed exercise and the monitoring of the health care as prescribed and monitored by CLBP and health care practitioner (Wright, Golder, Lewis-Light, 2015). Randomizing the controlled trials. Measuring the clinical outcomes regarding pain and advising the patient regarding the pain reduction and improving function. The determination that is made provides focus with the creation of the enhancement for the controlling of the criteria developed and thereby it also helps in the creation of development criteria for the enhancement and also the systematic review is considered. Henceforth the disability of the outcomes are not identified instead fruitful outcomes are identified with the utilization of the evidence that are created regarding the pain scales. Henceforth the intervention criteria is seemed to be more effective in the case of the back pain and thereby the systematic review is created with the further continuation of the treatment considered for CLBP. The retrospective formation of the physiotherapy is used with the creation of the quality assessment tool with thereby also helps in the creation of internal validity and thereby the increment of statistical value is also seen regarding RCT controlled trials used by the usage of acupuncture.
