Best Deicer Types and How to Use

The best deicer is the non-chemical backbreaking solution... the snow shovel. However, proper use of a chemical deicer can ease your battle with snow and ice. Note that proper use is key, since a big issue with deicers is that they are used incorrectly. You want to use the minimum amount of product needed to loosen the snow or ice and then remove it with a shovel or plow, not cover the surface with deicer and wait for the salt to completely melt the snow or ice. Which product you use depends on your specific needs. Key Takeaways: Best De-Icer Solutions There are many de-icing products. Each product offers advantages and disadvantages. Considerations include cost, environmental effects, and temperature.Some products are ineffective at extremely low temperatures.In order to any product to work, a tiny amount of melted water is necessary. In the past, regular table salt salt or sodium chloride was the usual choice for deicing roads and sidewalks. Now there are several deicer options, so you can choose the best deicer for your situation. The Transportation Research Board offers a tool to help you compare 42 deicer options based on price, environmental impact, temperature limit for melting snow or ice, and the infrastructure needed to use the product. For personal home or business use, youll probably see only a few different products on the market, so heres a summary of some of the pros and cons of the common deicers: Sodium chloride (rock salt or halite) Sodium chloride is inexpensive and helps keep moisture from accumulating on roads and walkways, but it is not an effective deicer at low temperatures [only good down to -9Â °C (15Â °F)], damages concrete, poisons the soil, and can kill plants and harm pets. Calcium chloride Calcium chloride works at very low temperatures and isnt as damaging to the soil and vegetation as sodium chloride, though it costs a bit more and may damage concrete. Calcium chloride attracts moisture, so it wont keep surfaces as dry as many other products. On the other hand, attracting moisture can be a good quality since calcium chloride releases heat when it reacts with water, so it can melt snow and ice on contact. All deicers must be in solution (liquid) in order to start working; calcium chloride can attract its own solvent. Magnesium chloride can do this too, though it isnt used as commonly as a deicer. Safe Paw This is an amide/glycol mixture rather than a salt. It is supposed to be safer for plants and pets than salt-based deicers, though I dont know much about it otherwise, except that it is more expensive than salt. Potassium chloride Potassium chloride doesnt work at extremely low temperatures and may cost a little more than sodium chloride, but it is relatively kind to vegetation and concrete. Corn-based products These products (e.g., Safe Walk) contain chlorides and work in very low temperatures, yet are supposed to be safe for yards and pets. They are expensive. CMA or calcium magnesium acetate CMA is safe for concrete and plants, but it is only good down to the same temperature as sodium chloride. CMA is better at preventing water from re-freezing than at melting snow and ice. CMA tends to leave a slush, which may be undesirable for sidewalks or driveways. Deicer Summary As you would imagine, calcium chloride is a popular low-temperature deicer. Potassium chloride is a popular warmer-winter choice. Many deicers are mixtures of different salts so that you get some of the advantages and disadvantages of each chemical. If you live in an area that gets snow and ice, your local hardware store likely offers good solutions. The obvious advantages of buying products at stores include supporting your local economy and saving some money on shipping. If you shop online, shipping may be free, but its likely included in the price in one way or another. Household Products That Work In a pinch, you can use common household products as de-icing agents. Basically, any product that contains salt or sugar will work. Examples include liquid from a pickle jar, sugary soft drinks, or a homemade solution of salt or sugar in water.

Observations of Nonverbal Communications Between Two Strangers Charlie Steward University of Alaska Anchorage Fundamentals of Oral Communications Fall 2017 Professor Peyton Introduction When most of us think about communication, many of us immediately imagine ourselves talking to someone or writing them a message. Most of us do not actively think about the equally or more likely, much more important nonverbal cues that are very much a part of how people perceive our chosen messages. The main types of nonverbal communication cues that I focused on while I was observing my subjects were: †¢ Kinesics, the gestures we make or how we move about when we are communicating. †¢ Haptics, the way we interpret things physically. †¢ Appearance,†¦show more content†¦He had a newspaper folded neatly in front of him. The woman, her mostly gray blonde hair freshly styled and worm to just below her shoulders, wore a blue medium-heavy summer jacket with a very colorful scarf wrapped around her neck. Her pants were comfortable looking jeans, and her shoes were almost new looking black flat walking shoes. She only had a cup of tea in front of her with two bags, which she dipped up and down constantly until she pulled them out and began drinking. They both wore wedding bands on their ring fingers. I would imagine them both to be in their late sixties to early seventies. Relationship These two people were obviously, to me, man and wife, as they leaned toward each other and kissed on a couple of occasions during my time observing them. In the first few minutes, I noticed that the woman would sometimes reach her hand out and rest it on the man’s forearm, smiling at him and gently patting and caressing his forearm as she did but would also appear as though she wasn’t really paying much attention to what he was saying a lot of the time. The man would constantly smile and once even took his wife’s hands in his to gently kiss them before letting them go. He would also talk, at great length, about something I can only imagine was possibly boring or had been talked about before in the relationship. The constant eye contact while talking and occasional touching and kissing lead me to the conclusion that these were two peopleShow MoreRelatedNonverbal Observation Essay1111 Words   |  5 PagesNONVERBAL COMMUNICATION INTRODUCTION On September 12, 2008, I observed two people; Person A and Person B.

Digital Telecommunications and Network Free Essays

A network is defined by Noergaard (2005) as a collection of two or more connected devices that can send or receive data. He further adds that the relationship between these connected devices in a network determines the total architecture. The purpose of this report is to understand the networked applications architectures. We will write a custom essay sample on Digital Telecommunications and Network or any similar topic only for you Order Now Two networking architectures are covered here; the client/server architecture and peer-to-peer architecture. The report first gives an outline of these two architectures and their advantages and disadvantages. It is seen that the industry divides its products on the concept of client-server model or peer-to-peer model. Some applications perform better with the former model while others perform better with the later model (Klemt 2005), 1992). Based on the understanding of this report, two separate scenarios for a basic networking application will be analysed. The idea will be to judge the type of networking architecture to be used for each scenario. Finally based on the entire analysis, a conclusion will be drawn as to which resource has to be used in what situation. Part 1: Review of Client/Server and P2P application architecture Client/Server architecture Client-network computing is one of the most basic paradigms of distributed computing, and this architecture is based on the paradigm as described by Jalote (2005). This architecture has a minimum of three components – a client, a server and a network that connects these two systems. This is a two level architecture where a client requests a service and the server provides it (Singh 2005). The server is usually accessed through a remote procedure called RPC, request of which is defined by their signature. The processing of the request is internal to the server and is transparent to the client. The client and server may be on different or same systems Advantages of client/server architecture Client server architecture using RPCs has been used for over a decade for system wide exchange computing (Singh 2005). The main reason for this is the high level of reliability this architecture provides. It is also found that the cost of the entire system over a period of time is less than that used by other architectures. In addition, the architecture also enhances safety since any of its components can be removed without a major impact on the other system. This architecture leads to a better distribution of resources through the system. This architecture also leads to increased productivity because the front and back end distribution of processes is optimised (Jalote, 2005). Disadvantages of client/server architecture The main disadvantage of the client/server architecture is that there are multiple databases in the client/server environment, making the management and synchronizing of the data shared between them difficult. This also leads to a difficulty in software distribution and configuration management program, as the system is distributed. The cost of maintenance may also increase because of the different networks being inter-networked. P2P architecture Peer-to-peer or P2P architecture is another way of managing distributed applications. In this method, the individual nodes have similar and comparable roles, unlike the client/server systems. In this architecture, the nodes are given roles such that both can act as client and server. This type of connection requires at least two computers connected to each other (Reid, 2004). In order to function correctly each node of the system should know the address of at least another node. Each node can directly contact the other node of the system for using its resources, without going trough the server (Heathcote Langfield, 2004) Advantages of P2P Architecture This type of communication exists since the time of old IBM PCs. The primary advantage of a P2P network is that it is fault tolerant and there is no single location for the fault. This means that the system works well even when several of its components are missing (Verma, 2004). Also the combination of processing power of multiple nodes in a network greatly increases the efficiency of the system in terms of combined processing power and storage when compared with a central server. P2P systems are hence extremely autonomous and can secure anonymity. They can be generally deployed in an ad hoc system without requiring central management or control. Finally, unlike the client/server systems there is no need for a separate network operating system (Reid, 2004). Disadvantages of P2P Architecture The manageability of peer-to-peer systems is much harder, due to the extremely distributed nature of the system. Security is also not centrally controlled and the users need to remember different passwords for accessing the resources located on different nodes on the network (Porter, 2006). Facilities such as backup are the responsibilities of the individual user unlike the client/server systems where the server can schedule them. This system works best for lesser number of systems in a network, usually under 10 (Reid, 2004). Part 2: The architecture of Mr. Robertson’s home network Network Architecture The architecture which I would suggest for Mr. Robertson’s home would be a peer—to-peer network. There is no necessity for a client/server model in this case. Also no type of hub system is required, since the application is very simple Justification As is already explained in the section above, a peer-to peer network is used for ease of applications without extra overload. The system works best for systems which having less than 10 systems. As Mr. Robertson’s system uses only two computers, the system is ideal for this purpose. In addition to this, the home network does not require the additional overhead of a server so a pure peer-to-peer system, one without any server (Subramanian Goodman, 2005), can be used. The application mainly used is the file sharing which can be easily done. Also for using the internet, there is no necessity for the system to have simultaneous connections as is already mentioned in the example. While, to most intents and purposes, a printer application requires the use of a server so as to manage the print request being sent from multiple systems, this is clearly not the case here. The network should merely have the capability to receive print jobs from both the systems a simultaneous operational capability is not really required, as the application would not be too critical. In the worst case, the print job could be cancelled and given again. Finally, the use of a client server system would in addition to setting a server, also need additional components and software like an operating system, which is not required in this case, as there is no need for tasks like allocation resources, backups etc. Also, Mr Robertson gets the advantage of removing any of the two systems from the network at anytime, and the second component would work just as well, as neither of the system is a server. Components for the home network In addition to the 2 computers and printers purchased by Mr. Robertson, he needs very few components to get his system up an running. He would need the cable modem, a twisted cable pair, media converter for running the internet through cable, a splitter and a print sharer. There is no necessity for a hub for such a system, which is necessary only if there are more than two computers on a network. The splitter would divide the internet connection to the two systems which will the function of the print sharer also. A wireless NIC or a wired one can be used to share the network. Only single numbers of components, except the connecting cables, are needed because there are only two computers. Topology of the home network The figure above shows the basic topology of the network. As explained above, there is no need for a hub for just 2 systems. The printer can be connected either via a print sharer or the software can be used to do that by accessing the network. Here, each computer can access the network printer. In addition, the cable connection that comes can be split into two using a splitter. This type of networking requires basic minimum of components and can be used for connecting systems on a home network. This system is extendable to more than two systems. The only difference would be that in that case, a hub would be used between the two systems instead of just a cable. Also the cable type, which is twisted in this case, might be changed for more than two computer systems, because of load factors. In this case also, there will not be any necessity for a server, as the printer tasks will be shared, but not scheduled or managed by an external system. Part 3: The architecture of the LAN of BC Inc. Network Architecture For the company’s LAN, a client server system is a must. There are only 16 systems, on the LAN would more than fulfil the application necessity. There are multiple applications needed for this system. There is the printer service which is multiple in numbers and locations. In addition, there is the obvious necessity for an email and web server for the business applications. All this necessitates are need for the use of a client/server model. Justification In many of the situations given above the peer-to-peer network fails to have any use. First and foremost is the number of systems. The P2P system is only suitable if the number of systems is less than 10, as mentioned earlier. Also it is not just the number of system that is a problem, since it is not a very huge network. Office applications as a rule need more features and functionality than a home based server, and so the load on the network contributed by each system is also a lot. In addition to this there is he additional necessity for security and backups as compared to the home networks. People usually prefer manual backups on their home networks, but almost all the companies insist on having scheduled backups for the protection of data. In addition, the systems also need to have security updates with a controlled installation, which is not necessary for a home network, whose security necessities extend maximum to having a basic firewall. As in earlier case, due to data sensitivity, companies prefer to have all of these controlled rather than leaving it to the discretion of the office employees. There is an obvious burden due to the higher cost of installation and maintenance of the system. But this is more than compensated by the quality of security and safety levels given by such a system. Also since, there are only 16 employees in the system, it is logical to have the email server as the same as the network server. This is also true for the web server applications. However, here there is an assumption being taken. It is assumed that the company business is a small size, based on the number of people working there. This may very well not be the case. In addition to this, the web sever installation might be mandatory on an external system, because of security reasons. For instance, the company might not want its intranet lined with its webserver to provide more security. This case might necessitate the need for a separate web server, though for this report, a single sever is being considered for now. Physical Components In addition to the computer systems and printers, the company needs many additional systems to make a network. First and the most important of this is the server system, which needs be high ended, with high processing power and speed. This is that the system can easily act as a intranet server, a mail server, and also the web server. In addition to this a router is essential for connecting to the internet via the DSL modem. Also there are multiple numbers of cables, based on the systems connected to the network. Since the system is connected via the Ethernet here, the internet being a DSL based one; the corresponding cables are also required. The printer is connected to the server, which takes care of the scheduling the print jobs. The other servers, as mentioned earlier are situated on the main server itself. The figure above shows the scheme of the connection diagram. The above diagram is a very simplistic way of representation of the office network. As mentioned above, the server would be common from email and web applications, and also take care of the intra networking scheme. In addition, the various printers and DSL modem would be added to this server only. The server would need a network operating system and the main security firewalls and the protection schemes like the antivirus would be installed here. Ethernet would be the mode of interconnection in the network. The system can be extended when a new web server is required, which is separate from the present server. There can be another server attached to the present one which would take care of the business related websites etc. The connection would be restricted so that only the purchase related or feedback related information is passed to the main server, which would then direct this information to the necessary client system. Conclusion In the report mentioned above, there were two types of networking architecture which were analysed. One was the client server architecture, which is one of the oldest networking schemes available. The system finds its use in complex networks having many systems, and necessity for multi-file sharing applications, common or shared database and also security. All these are provided by this system, which the case seen by the company example is being taken here. The operations are very complex with multi-printers and their multiple locations, the necessary for common access to the internet, and also the need for servers for websites and emails. Also the network needed security and will be needed managed access permission for files stored on the network. The restricted type of entry for a network is possible only for a client and server type of architecture, which is what was proposed for this case. The company being an accounting firm would also need internal data restrictions and security issues, which can only be tacked by this architecture. In contrast, the home networking system is a very simple operation, which needs to have a mere connection to the internet and the use of a printer. There are no constraints of security or access restrictions on this systems and the main application need is a basic file share operation. For such a system a basic, peer-to-peer architecture is sufficient. There is no need for hubs also as there are only two systems. The network does not need any server based system which is too much of overkill here. Hence, using these two examples, the two types of networking architectures are explained here.

A Review of the Role of Entrepreneurship in Stimulating Economic Growth free essay sample

They also further states that entrepreneurs have been responsible for growth and development over the centuries and are identified as the key role players in the economy of every country. The paper identifies the different definitions of an entrepreneur which are identified as the different channels in which entrepreneurship lead to economic growth, reduced unemployment and increased levels of income among countries. As a result of the role of entrepreneurship in any country, most countries emphasises on integrating entrepreneurial activity in its economic policy. A discussion is made on developing economies mainly South Africa, China, Brazil and Russia comparing the entrepreneurial activity within the economies. Economic growth is best defined as a long-term expansion of the productive potential of the economy. It is measured by the comparing the difference between the Gross National Product (GNP) in a year with the GNP of the previous year. A growing economy is when the difference is positive. We will write a custom essay sample on A Review of the Role of Entrepreneurship in Stimulating Economic Growth or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The term simply refers to an increase in the ability to produce goods and services. It is easier to define unemployment when there is an understanding of the term economic growth. Unemployment refers to when a person who is actively searching for employment cannot find work to do. This is an instrument used to determine the healthiness of an economy. After knowing the levels of unemployment in an economy, determining the level of income distribution becomes a bit projected. The level of income in an economy refers to the way in which in money is distributed among the population in an economy. The above three defined terms has a link to each other. The level of economic growth have a direct proportional influence on the possible jobs available in the economy while a reciprocal relationship exist between the level of income in the particular economy and levels of unemployment. The level of income is directly proportional to economic growth. Also, the level of unemployment is directly proportional to the level of income in an economy. However, all the above aspects are influenced by the level of entrepreneurship in the particular economy. An economy with high activity of entrepreneurship is more likely to be characterized by high economic growth, reducing levels of unemployment and increasing levels of income while an economy with low entrepreneurial activity on the other hand can be characterized by low economic growth, high levels of unemployment and low levels of income. Entrepreneurship cannot be separated from the following terms â€Å"economic growth†, â€Å"employment† and â€Å"country income level distribution† as all the entrepreneurial activities contribute largely to economic growth, levels of employment and income distribution. Different nature of entrepreneurs stimulates the growth of an economy in different ways. In any country with high levels of entrepreneurial activities or which experienced high entrepreneurial activity, the economy tends to be of middle to high income and the unemployment levels tend to be decreasing if not low. However, economies with low income distribution are characterised by low entrepreneurial activities and mostly, there are significant levels of unemployment. Such low income economies have high records of poverty which leads them to seek donors. Different authors made contributions on this topic and this paper compares and links the information obtained into a comprehensive review. The term entrepreneurship has been defined by Schumpeter (1934) as lying in the perceptions and exploration of new opportunities in the realm of business. He further states that it always has to do with bringing about a different use of resources in that they are withdrawn from their traditional employ and subjected to new combinations. Schumpeter relates entrepreneurship to be influenced by entrepreneurs who are innovative and hese people have to be extra-ordinary as they have to come up with extra-ordinary events. They come up with new technological possibilities hence are able to establish large businesses from these. Carland etal. (1984) confirms that an entrepreneur is someone innovative and further says that he or she employs strategic management practices in the business. Timmons (2000) believes entrepreneurship as the process of creating a nd seizing an opportunity and pursuing it, regardless of resources currently controlled. Nieman and Nieuwenhuizen (2009) define an entrepreneur as the person who sees an opportunity in the market, gathers resources and creates and grows a business venture to meet these needs. They also further states that he or she bears risk of the venture and is rewarded with profit if it succeed. With different definitions of entrepreneurship defined by different authors through the way they define an entrepreneur, the researcher generally defines entrepreneurship as the act of being an entrepreneur who establishes business through the organisation of resources taking risk with the aim of realising profit. The Schumpeterian entrepreneur as defined above is innovative. In support for this, Curran and Stanworth (1989) defines entrepreneurship as the creation of new economic entity centred on a novel product or service or, or at the very least, one which differs significantly from products or services offered elsewhere in the market. Such entrepreneurs play a very crucial role in stimulating economic growth. They come up with huge organisations which can be monopolies in the economy. With the nature of big businesses, they would be more likely to produce large volumes of product increasing the GNP thereby contributing significantly to economic growth. With their capacity to produce large volumes, such organisation would take considerable number of employees hence reducing unemployment. By employing people, such entrepreneurs contribute to the increased levels of income in an economy. Another author Kirzner presents a different way in which entrepreneurship can be influenced by an entrepreneur through the way he defines an entrepreneur. According to Kirzner, the entrepreneur is someone who is alert to profitable opportunities for exchange. Such an entrepreneur believes in gathering the needed information, refining and providing it to those in need of it. Such entrepreneurs act as intermediaries for example between suppliers and customers. They are also very important in the growth of an economy as they facilitate inception, incubation of businesses through the provision of supportive information. The information they provide acts as a catalyst into venturing into business and builds confidence to emerging businesses. Emerging businesses require business support for them to have high chances of success hence the Kirzner entrepreneur makes the perfect match for such new businesses whose success lies on business support services. Such an entrepreneur can offer business support services such as business counselling, business mentoring and business incubation.
