How to Make a Desiccant Container

How to Make a Desiccant Container A desiccator or desiccant container is a chamber that removes water from chemicals or items. It is extremely easy to make a desiccator yourself using materials you probably have on hand. Have you ever wondered why so many products come with little packets that say Do Not Eat? The packets contain  silica gel beads, which absorb water vapor and keep the product dry. Including packets in packaging is an easy way of preventing mold and mildew from taking their toll. Other items would absorb water unevenly (e.g., parts of a wooden musical instrument), causing them to warp. You can use the silica packets or another desiccant to keep special items dry or to keep water from hydrating chemicals. All you need is a hygroscopic (water-absorbing) chemical and a way to seal your container. Key Takeaways: How to Make a Desiccator A desiccator is a container used to maintain a low-humidity environment.Dessicators are simple to make. Basically, a dry desiccant chemical is sealed within a closed container. Objects stored within the container will not become damaged from moisture or humidity. To some extent, a desiccator can absorb water already stored within an object.Many desiccants are available, but they vary widely in terms of safety and cost. The safest chemicals to use include silica gel beads, calcium chloride, and activated charcoal.Desiccant chemicals can be recharged by heating in order to drive off the water. Common Desiccant Chemicals Silica gel is the most widely available desiccant, but other compounds work, too. These include: Silica gel (the beads in those little packets)Sodium hydroxide (sometimes sold as a solid drain cleaner)Calcium chloride (sold as a solid laundry bleach or a road salt)Activated charcoalCalcium sulfate (gypsum or plaster of Paris)ZeoliteRice However, some of these chemicals are more effective and safer than others. Rice, for example, is extremely safe. It is often added to salt shakers as a desiccant to prevent water absorption, allowing the seasoning to flow through the shaker. Yet, rice has a limited ability to absorb water. Sodium hydroxide and calcium chloride are extremely effective, but sodium hydroxide is a caustic compound capable of producing chemical burns. Both sodium hydroxide and calcium chloride eventually dissolve in the water they absorb, potentially contaminating objects stored within a desiccator. Sodium hydroxide and calcium sulfate evolve considerable heat as they absorb water. If a lot of water is absorbed within a short amount of time, the temperature within the desiccator may spike dramatically. In summary, for a basic home or lab desiccator, silica gel and activated charcoal may be the two best choices. Both are inexpensive and non-toxic and dont degrade upon use. Make a Desiccator This is extremely simple. Just place a small amount of one of the desiccant chemicals into a shallow dish. Enclose an open container of the item or chemical you wish to dehydrate with the container of desiccant. A large plastic bag works well for this purpose, but you could use a jar or any airtight container. The desiccant will need to be replaced after it has absorbed all of the water that it can hold. Some chemicals will liquefy when this occurs so that you will know they need to be replaced (e.g., sodium hydroxide). Otherwise, youll just need to switch out the desiccant when it starts to lose its effectiveness. How to Recharge a Desiccator Over time, desiccants become saturated with water from humid air and lose their effectiveness. They can be recharged by heating in a warm oven to drive off the water. The dry desiccant should be stored in a sealed container until use. Its best to expel all of the air out of the container, since it contains some water. Plastic bags are ideal containers because its easy to squeeze out the excess air. Sources Chai, Christina Li Lin; Armarego, W. L. F. (2003). Purification of Laboratory Chemicals.

Tips for Attaining Editorial Consistency

Tips for Attaining Editorial Consistency Tips for Attaining Editorial Consistency Tips for Attaining Editorial Consistency By Mark Nichol How much time and effort should a writer put into consistency? And how much energy should an editor devote to it? The answer, as with many editorial issues, is not that simple, but it is easy to elucidate. A book or a book-length publication, such as an extensive report, must for the sake of a reader’s respect for the authority of the argument and/or the regard of the care taken by the writer, strive for flawless consistency in all regards. But note that â€Å"flawless consistency† does not necessary mean â€Å"precisely the same every time.† If not, what does it mean? When an entity, whether a person or a company or organization, is mentioned repeatedly in one document, of course the name should be spelled correctly each time. But there are acceptable variations to the treatment of the name. When a biography of Sir Arthur Conan Doyle, for example, names him for the first time, the reader should see those four components of his name. But his last name alone is sufficient thereafter with exceptions. An emphatic reference to his strength of character may require a stylistic flourish: â€Å"But Sir Arthur Conan Doyle wasn’t about to let her get away with that.† A quotation in the book may refer to him before he was knighted, or the person quoted may simply have omitted the honorific. Complicating matters, it appears that later in life, the creator of Sherlock Holmes preferred to use â€Å"Conan Doyle,† though without a hyphen, as his surname, so the writer must decide whether to use the single surname or the double version and must do so consistently. By the same token, a company or organization name is often spelled out only the first time it is used, and is then referred to by a short form (for example, Dow, rather than Dow Chemical Company) or an acronym or initialism (NASA, rather than the National Aeronautic and Space Administration, for instance). As with a personal name, there’s no reason to revert to the full name outside a quotation or some other anomalous usage. And what if a book is a collection of essays by various writers? The editor of the anthology is responsible for establishing a style that remains consistent throughout unless, of course, one or more contributions are previously published in a differing form of the language, such as an essay by a British English writer among American English authors. The editor may edit the essay to conform to American English style, but it’s easier to leave it as is and acknowledge the discrepancy in the introduction or in a note. As for treatment of names, an anthology’s editor might choose to resume full forms at the beginning of each chapter to reacquaint the reader, then resort to short forms or abbreviations after each chapter’s first reference. In the case of words with more than one correct spelling, such as adviser/advisor, the copy editor simply notes the preferred spelling on a style sheet while working on a manuscript and performs a word search for any instances of the nonpreferred spelling and corrects them. Alternatively, the copy editor can simply note that the manuscript, as edited, conforms to the primary spelling in the dictionary. (Many publications use this policy as a simplifying default setting to prevent ambiguity about which spelling to employ.) Periodicals, as well as book publishers and many other companies and organizations that publish, generally have a style guide, which prescribes treatment of pertinent names and terminology; for example, an industry-focused magazine about architecture may routinely refer to the American Institute of Architects by its initials alone because the publication’s readers do not require a complete identification, and a journal about US history will dictate that all references to indigenous bovines specify bison, rather than the inaccurate popular variant buffalo. A carefully compiled style guide will document these policies, and a diligent copy editor will consistently honor them. (Writers are often unaware of the rules governing editorial inconsistency, or are not careful about applying them, and in the worst cases do not think doing so is their responsibility, or even necessary.) Web sites with user-generated content, as opposed to those that, like print publications, have an editorial staff, cannot expect all contributors to conform to style and will thus be flexible about consistency, though any text generated by the site staff should adhere to the prescribed style.

The Big Bowl Part2 - Essay Example The skipper is then notified of a successful registration. The system administrator is charged with the responsibility of updating scores during matches. The system Administrator fills in the match details and the system displays the teams playing the particular match. He or she fills in the new results using the score update sheet and this is update into the system. The system then automatically displays the highest score after the new update (Ambler 79). The classes are Match, Team, Player, Scores and Venue. Match class has the matchID attribute which is used to uniquely refer to a given match. The class also sets the time match takes place and can be able to get scores of a given match from Scores class. Player class has attributes that give more information about a player, that is, name (name of the player), age (his age), fieldPosition (the position he plays in the field) and his identification number (PlayerID). Match table contains column names matchID (unique number identifying each match), matchTime (time when the match takes place), placeName (venue of the match), and scores. matchID links to matchID in team to identify the matches the team took part in and in scores to identify the scores of that match. PlaceName links to placeName in venue and is used to identify the place the match took place. This will define the general approach for the implementation of the system. The point and intent will be to identify the assumed facts and establish a way to fuse the system to the domain area. Most importantly identifying the activities that will be handled in implementation will address the system development stage of completion. Infrastructure communication, this will look at the roles of people in the organization to provide the network, information and communication infrastructure. The chief intent here is to support the application on the internal company network. Second,

Interview Summary with Xiaochu of BenMo PR Essay

Interview Summary with Xiaochu of BenMo PR - Essay Example She denied the college life keeping her eye on the future needs which demanded her to â€Å"get her life started and going as soon as possible†. Her finance needs led her to the modeling area and bartending but soon her creativity persuaded her on starting her own blogs on the internet and she captured the attention of huge followings quickly. Xiaoxhu maintained her double identity i.e. her real-life identity and her virtual identity in all this time period. However, she was quite successful in maintaining her reputation under both identities. In the virtual world, she was named as the best blogger in four of the prevailing web networks, Sina, Sohu, Xici, and Tianya. She was voted as the Beauty Blogger in both Tianya and Sohu and was elected to be the â€Å"basketball babe† for the 2008 Beijing Olympics website. On the other hand, her real life activities involved her service as an editor for a local Shanghai magazine and she was also on the organizing committee for the 57th World Beauty Pagent. This illuminates her ambition of not accepting the life and circumstances as they are but to develop her career and achieve her ultimate aim of being a successful person. The goal of such hardworking and ambitious people is sometimes to achieve comforts of life, wealth or some other kind of financial benefit. However, Xiaoxhu â€Å"never saw money as the main goal.† She further illuminates this idea by asserting that â€Å"even at the beginning money was just something to put food in my mouth and a roof over my head.† This clearly shows that her aims were not limited to grabbing money and leaving this world without being seen or noticed by others. Her aim was to capture the general public and make her name known to them in good words. Her success was accompanied by the achievement of her goals in her own distinct way of attracting public, specifically general public. In support of her

Gulf War :: essays research papers

The Gulf War   Ã‚  Ã‚  Ã‚  Ã‚  In the early morning of August the second 1990, Saddam Hussein and a fleet of tanks as well as 100,000 thousand troops invaded neighboring Kuwait with out provocation or warning. Iraq also had surface-to-surface missiles to take complete control of Kuwait; this all took place just hours after Saddam Hussein had assured neighboring countries that there would under no circumstances be an invasion. George Bush entered the Gulf War for the sole reason of recovering the oil and Kuwaiti Boolean that Saddam Hussein had stolen. President George Bush’s goal in entering the war was to recover the stolen oil from the Iraqi’s, and ensure that it continues to be sold at a reasonable amount by the Kuwaiti’s, rather than have the prices raised or even the threat of being cut off by Saddam Hussein; there was also an extreme threat that the Iraqi’s possessed nuclear weapons which would endanger all bordering countries. The President said that anything less than the full cooperation of the Iraqi troops and tanks would result in immediate action by the U.S troops in his address to the people. Bush also demanded that full restoration of the Kuwaiti government must also take place rather than the puppet regime that was established by Saddam Hussein after his take over. This was one of the many incidents that lead President George Bush to take action against the Iraqi’s due to their involvement in the Persian Gulf crisis.   Ã‚  Ã‚  Ã‚  Ã‚  The United Nations placed sanctions upon Iraq, which lead to the starvation of one point two million Iraqi civilians. It was also the cause of the famine rate amongst children from the age five and below to rise almost one quarter from its rate the previous year. 960,000 women and children dead due to the sanctions brought forth by the UN. The sanctions, which were brought forth, involved the immediate hold put on all food, clothing, and medicines from entering Iraq. The points of the sanctions were to weaken the strength of Saddam Hussein and his task forces. In July of 1997 the U.S government held a press conference stating that it was indeed true that the figure was actually well over one point two million Iraqi civilians were killed due to the sanctions. This was one of the major set backs in the campaign of President Bush among the people.   Ã‚  Ã‚  Ã‚  Ã‚  Another fact that set President Bush back was the belief of the people that it was not worth putting the lives of American troops on the line for oil.

Handle information in health and social care setting Essay

Outcome 1 Understand the need for secure handling of information in health and social care Identify the legislation that relates to the recording, storage and sharing of information in health and social care The Data Protection Act 1998 covers anything relating to a person, medical records, social service records, credit information, local authority information. There are eight enforceable principles: Personal data shall be processed fairly and lawfully Adequate, relevant and not excessive Accurate Not kept for longer than necessary Process in accordance with the data subject rights Not transferred to countries without adequate protection The Data protection Act also allows people to see information recorded about them through the Freedom of Information Act 2000, therefore people are allowed to see their social care files, this is important to know when entering information in people’s notes. The ICO Information Commissioner’s Office is responsible for upholding information rights in the public interest. Explain why it is important to have secure systems for recording and storing information in a health and social care setting Information on Care homes and in house information is valuable and critical to the business of the home. This information must be stored and processed therefore it is essential that Information Security is maintained. The purpose of information security is to preserve: Confidentiality data is only access by those with the right to see them. Integrity information can be relied upon to be accurate and process correctly. Availability information can be accessed when needed. Insecure information can lead to violation of an individual’s human civil  rights that may results in neglect/or physical, sexual, emotional or financial harm. Manual system of recording information has to secure so they are usually kept in a locked cabinet and may be in a secure room. Outcome 2 Know how to access support for handling information Describe how to access guidance, information and advice about handling information The first place to look for guidance and advice is the supervisor with regards to information in the work place. If you require information about a person, then that person’s care plan would be ideal. Information about legislation to ensure that you are complying with the law, them the Information Commissioner’s Office is the place to contact. Explain what actions to be taken when there are concerns over the recording, storing or sharing of information If there is a concern relating to people’s records, the concern should be directed to the manager who is in the position to deal with the concern. For taking a concern further that has not being resolved, the concern needs to be : Put in writing Be clear about dates, times and the exact nature of the concern Identify the steps that have already been taken and the response Involve trade union or professional organisation for support The steps for resolving concerns: Discuss with line manager Record the concerns and take it to a more senior manager Take it to director or chief executive Take it to the inspectorate You are protected from unfair dismissal by an employer through the Public Interest Disclosure Act 1998 if your concern relates to the employer. Outcome 3 Be able to handle information in accordance with agreed ways of working Keep records that are up to date, complete, accurate and legible Records should provide objective, accurate, current, comprehensive and concise information concerning the condition and care of the client. The records kept should reflect an accurate and up to date picture of somebody’s situation. Records are kept to: Provide a full assessment of the client’s  needs Provide record of any problems and the actions taken Provide evidence of care required Provide a baseline record against which improvement or deterioration may be judged Records should le after be made as soon as possible after the event providing current information on the care and condition of the person. Follow agreed ways of working for: Recording information Good recording of information supports good practice in a number of ways. Supports effective partnership with users and carers, provides documented evidence and account of the department involvement with an individual, support risk assessment and risk management plans. The principles for recording:- Service users and carers are helped to understand the purpose and contents of their case record and are invited to contribute to it. Case records will be kept in accordance with Department of health guidance and legal requirements. Storing information A care plan contains valuable information about a person in care and this information has to be stored. All documents are stored according to legal, organisational and ethical standards. Some information can be stored and displayed openly, i.e. menus can be stored in a kitchen. Documents, such as care plans, medication sheets, and employee files need to be stored in locked cupboards in locked rooms to deny access to those who have no right to the information. Sharing information  the home has a general duty in common law to safeguard the sensitive information they hold of individual’s. The home should have a clear policy on the Data Protection Act which staff should adhere to. It is important that staff should pay particular attention to ensuring consent to share information is clearly recorded on file. Where it has been necessary to  share information without consent then the justification should be recorded and authorised by the line manager. There are different reasons for sharing personal information without consent:- Court or tribunal orders A person’s best interest Risk to health Police request Public interest Protection to others Partner agencies providing support. It is important that you know the policies of the care organisation with regards to confidentiality and the disclosure of information in your workplace. The basic rule is that all information is confidential and cannot be shared with anyone without the consent of the person.
