Plastic Fantastic-recyclage des plastiques dans la production d'acier

Fantastic Plastic ingénieurs à l'Université de NSW ont mis au point une façon de réutiliser les déchets de plastique pour produire de l'acier. «En Australie, chaque année plus de 1.000.000 tonnes de plastique est mis en décharge. «Seulement 10% des déchets plastiques totale sont jamais recyclés. University of NSW ingénieurs ont mis au point un procédé qui combine des déchets en plastique, ce qui devrait normalement être mis en décharge, et l'a combiné avec le charbon pour former de carbone, par le procédé sidérurgique, en utilisant un four à des températures de 1600 degrés C. Le carbone est combinée avec d'autres produits traditionnels et fondu dans un haut fourneau pour produire de l'acier. La recherche a démontré que les plastiques sont moins polluants que le charbon, fournissant ainsi une source d'énergie plus propres, qui est toujours important d'émissions de gaz à effet de serre de crise de la terre est confrontée. Le 9 août 2005, l'Université de NSW a remporté le prestigieux Australian Museum's 'Eureka Science Award »de la recherche scientifique.

Comment choisir un forfait - open source indices

Comme vous le travail par le biais du logiciel de processus de sélection, vous créez une analyse des besoins à agir à titre de référence. Cela indique ce que vous voulez de ce produit et l'importance de chacune des caractéristiques souhaitées. La prochaine étape est de trouver des produits qui sont des candidats potentiels et de déterminer comment ces produits répondent à vos besoins. Les possibilités sont infinies sources d'information sur les produits, de matériel de promotion mis en œuvre à votre bureau grâce à l'infinie quantité de matériel sur l'Internet. L'astuce consiste à déterminer ce qui est des ventes de battage et de ce qui est fait vérifiable, et qui peut être extrêmement difficile. Avec les produits conventionnels, vous avez vraiment de quatre sources principales d'information * Ventes de brochures * Du personnel de vente * Comptes de référence * Les groupes d'utilisateurs Pour les produits Open Source, il n'a pas tendance à être une force de vente, de sorte que vous devez suivre un chemin différent. Les meilleures sources que j'ai trouvé pour l'Open Source sont les forums et le wiki's. Maintenant que vous vous posez - ce sont celles qui sont le diable? Un Wiki est essentiellement une communauté a développé des efforts de documentation, ce qui tend à être le moyen de documentation est créé pour les produits Open Source. Pour couper une longue histoire courte - la documentation est élaborée par l'utilisateur et la communauté du développement. Un forum est un site sur Internet où les utilisateurs et les développeurs de communiquer sur un produit. Ces deux vous donne une bonne occasion pour impartial de vues sur le produit en question. Ok - assez pour le moment - plus tard ...... A propos de l'auteur: Lee est l'un des principes à Spinnaker Systems Web qui fournit des services liés à la petite entreprise.

Comment faire pour enregistrer une image dans une base de données SQL Server?

La plupart des applications Web ont un grand nombre d'images utilisées. Ces images sont généralement stockés dans un dossier de serveur Web et sont accessibles en donnant le chemin relatif au dossier en ce qui concerne le dossier racine du site. . Net est la plate-forme d'applications distribuées pour l'instant, ASP.Net peuvent être utilisés pour stocker des images qui sont petits pour être stockées dans une base de données comme SQL Server 2000 et versions ultérieures. À cet effet, la base de données SQL Server fournit un type de données appelé "image" qui est utilisé pour stocker des images dans la base de données. Pour accéder à ces images stockées dans la base de données, nous utiliserons la ADO.Net classes. Pour savoir comment insérer et d'extraire une image à la base de données SQL Server, vous pouvez créer une page. Aspx qui peuvent avoir un contrôle HtmlInputFile qui est utilisé pour sélectionner le fichier image qui doit être sauvegardé dans la base de données. Vous pouvez également créer un contrôle de texte dans lequel vous pouvez ajouter le nom de l'image ou d'une remarque ou une image id de l'image sauvegardée. Utilisez un contrôle de bouton pour télécharger l'image à la base de données. Namespaces comme System.Data.SqlClient, System.Drawing, System.Data, System.IO et System.Drawing.Imaging sont utilisés dans cette tâche. Dans la propriété OnClick du bouton, vous pouvez écrire le code suivant pour charger une image à la base de données. / / Créer un byte [] du fichier image qui est téléchargée imagelen int = Upload.PostedFile.ContentLength, byte [] picbyte = new byte [imagelen]; Upload.PostedFile.InputStream.Read (picbyte, 0, imagelen); / / Insérez l'image et l'image dans la base de données id SqlConnection conn = new SqlConnection (@ "donner à la chaîne de connexion ici ..."); try (conn.Open (); SqlCommand cmd = new SqlCommand (" insert into ImageTable "+" (ImageField, ImageID) values (@ pic, @ ImageID) ", conn); cmd.Parameters.Add (" @ pic ", picbyte); cmd.Parameters.Add (" @ ImageID ", lblImageID.Text), cmd. ExecuteNonQuery ();) finally (conn.Close ();) Vous pouvez aussi écrire le code ci-dessus dans une fonction et d'appeler cette fonction dans l'événement OnClick du bouton de téléchargement. Le code donné ci-dessus effectue les étapes suivantes dans le processus de l'insertion d'une image dans la base de données. 1. Obtenir le contenu longueur de l'image qui doit être téléchargé 2. Créer un byte [] pour stocker l'image 3. Lire les flux d'entrée de la file posted 4. Créer un objet de connexion 5. Ouvrez l'objet de connexion 6. Créer un objet de commande 7. Ajouter les paramètres à l'objet de commande 8. Exécuter la commande SQL en utilisant la méthode de ExecuteNonQuery l'objet de commande 9. Fermer l'objet de connexion Pour récupérer l'image de la base de données SQL, vous pouvez effectuer les étapes suivantes. 1. Créer un objet MemoryStream. Le code peut être quelque chose comme, MemoryStream mstream = new MemoryStream (); 2. Créer un objet Connection 3. Ouvrez la connexion à la base de données 4. Créer un objet de commande pour exécuter la commande pour récupérer l'image 5. Utilisez la commande de l'objet ExecuteScalar méthode pour récupérer l'image 6. Cast la sortie de la ExecuteScalar méthode à celle de byte [] byte [] image = (byte []) command.ExecuteScalar (); 7. Ecrire le flux mstream.Write (image, 0, image.Length) 8. Créer une image bitmap objet d'organiser le flux Bitmap bitmap = new Bitmap (stream); 9. Définir le type de contenu à l ' "image / gif" Response.ContentType = "image / gif"; 10. Utilisez la méthode Save de l'objet bitmap à l'image de sortie à la outputStream. bitmap.Save (Response.OutputStream, ImageFormat.Gif) 11. Fermer la connexion 12. Fermer le flux mstream.Close (); À l'aide des étapes ci-dessus, vous pouvez récupérer et afficher l'image de la base de données à la page Web. Vous pouvez utiliser ces algorithmes et de profiter de l ' «image» de type de données disponibles dans la base de données SQL Server 2000 pour stocker de petites images qui correspondent à un enregistrement dans la table de la base de données. Cette méthode évite de stocker la tâche pénible de suivre le chemin du répertoire web si les images sont stockées dans un dossier Web. A propos de l'auteur: Visite.

Coping with a Serious Data Loss from your Computer Hard Drive

Data loss is an expensive reality. It's a hard fact that it happens more often then users like to admit. A recent study by the accounting firm McGladrey and Pullen estimates that one out of every 500 data centers will experience a severe computer disaster this year. As a result, almost half of those companies will go out of business. At the very least, a data loss disaster can mean lost income and missed business opportunities.


The other side of data loss is the psychological and emotional turmoil it can cause to IT managers and business owners. Despair, panic, and the knowledge that the whole organization might be at risk are involved. In a sense, that's only fair, since human error is one of the two largest contributing factors in data loss. Together with mechanical failure, it accounts for almost 75 per cent of all incidents. (Software corruption, computer viruses and physical disasters such as fire and water damage make up the rest.)


Disk drives today are typically reliable. Human beings, it turns out, are not. A Strategic Research Corp. study done in 2000 found that approximately 15 per cent of all unplanned downtime occurred due to human error. A significant proportion of that happened because users failed to implement adequate backup procedures, either having trouble with their backups, or having no backup at all.


How does it happen that skilled, high-level users put their systems - and their businesses - at such risk?

In many cases, the problem starts long before the precipitating system error is made, that is, when users place their faith in out-of-box solutions that may not, in fact, fit their organization's needs. Instead of assessing their business and technology requirements, then going to an appropriate engineered solution, even experienced IT professionals at large corporations will often simply buy what they're sold. In this case, faith in technology can be an vice instead of a virtue.


But human intervention itself can sometimes be the straw that breaks the technology's back. When the office of a Venezuelan civil engineering firm was devastated by floods, its owners sent 17 soaked, mud-coated disks from three RAID arrays to us in plastic bags. A tough enough salvage job was made even more complex by the fact that someone had frozen the drives before shipping them. As the disks thawed, yet more damage was done. (After eight weeks of painstaking directory-by-directory recovery, all the data from the remaining fifteen disks was retrieved.)

Sometimes, the underlying cause of a data loss event is simply shoddy housekeeping. The more arduous the required backup routine, the less likely it will be done on a regular basis. A state ambulance monitoring system suffered a serious disk failure, only to discover that its automated backup hadn't run for fourteen months. A tape had jammed in the drive, but no-one had noticed.


When disaster strikes, the normal human reaction is panic. Because the loss of data signifies critical consequences, even the most competent IT staff can jump to conclusions, and take inappropriate action. A blank screen at a critical time can lead to a series of naive decisions, each one compounding the preceding error. Wrong buttons get pushed, and the disaster only gets worse. Sometimes the pressure to correct the system failure speedily can result in an attempt to reconfigure an entire RAID array. IT specialists are typically not equipped to deal with crisis modes or data recovery techniques. Just as a good physician is trained to prolong life, the skilled IT specialist is trained to keep the system running. When a patient dies, the physician turns to others, such as nurses or counselors to manage the situation. When significant data loss occurs, the IT specialist turns to the data recovery professional.


Data recovery specialists are innovative problem solvers. Often, the application of basic common sense, when no-one else is in any condition to apply it, is the beginning of the journey towards data recovery. The data recovery specialist draws on a wealth of experience, married to a "never say die" attitude, and a comprehensive tool kit of problem-solving procedures. Successful recovery outcomes hinge on a combination of innovative logistics, applied problem-solving, and "technology triage," the process of stabilizing an affected system quickly, analyzing and treating its wounds, and preparing it for surgery. The triage process sets priorities, such as targeting which files are needed first or which are absolutely vital to the functioning of the business, and establishes whether files might be recovered in less structured formats (such as text-only), which may be desirable when time is crucial.


The art and science of professional data recovery can spell the difference between a business' success or its failure. Before that level of intervention is required, though, users can take steps to ensure that the probability of a data loss disaster is minimized.


Basic to any business technology plan is a regular fire-drill procedure. Back-up routines may be in place, staff may assigned to specific roles, hardware and software may be configured - but, if the user isn't completely sure that everything works the way it should, a data loss event is inevitable. Having adequate, tested, and current backups in place is critical. A hardware breakdown should not be compounded by human error - if the malfunctioning drive is critical, the task of dealing with it should go to a data recovery professional.


Just as data loss disasters are rooted in a combination of mechanical failure and human error, so, too, the data recovery solution lies in a creative marriage of the technological and the human. The underlying philosophy of successful data recovery is that technology is something to be used by human beings, not something that uses us.

The Best gps device available

A common question today is 'what is the best device in gps technology available?' Well the answer to that question varies infinitely as one person may consider something good and another considers the same thing inferior. It is best to ask that question based on some common parameters like do you want an all round system? Are you willing to spend a little extra? Do you want a near custom made device? As far as gps devices go, Garmin, Magellan and Delorme are the top three manufacturers. For an all round gps device, the GPSMAP 60CSx from Garmin Company is a good bet. It has high accuracy in coordinating locations, a clear color screen that is readable even in sunlight; it is waterproof so fish tracking under water can also be an option. Along with the preinstalled maps a storage device in the form of a memory chip can be inserted to store extra maps or instructions that you would like to download. But consider this only if your pockets are extra deeps as with its unique barometric altimeter and compass its price rockets. The Explorist 500 LE from Magellan makes it to the second slot. Now the largest advantage to this hand held gps navigator is its price tag, it costs about a third of the GPSMAP 60CSx. The explorist gets the job done even if it does not use the latest when it comes to softwares. Its screen size though is 2.25 squared inches and is readable in most lighting conditions. This also has capacity to insert a memory stick and is also waterproof. This device is sensibility over style. Ranked number 3 is the Earthmate GPS PN-20 from Delorme Company. It is nearly as expensive as the number one device on the list but what sets this piece of navigating metal apart from the other two is the ability to show terrain, and it is surprisingly very clear on a 2.2 inch screen. The color display passed all tests when it came to readability and its accuracy isn’t bad either. It doesn’t weight much so carrying it around won't be a hindrance. Now all of the devices listed above were based on all round perspectives, naturally you the buyer will have your own personal requirements and the best way to achieve this is by testing a product yourself or picking something that will be stronger in one area but may lack another feature.
