San Francisco's Post Office opened by March 15, 1849 and its first postmark was a
manuscript, used from March 15 to June 20. San Francisco began using a postmarking
device on June 20, the straightline illustrated above, with the date written in
manuscript. Rates were indicated in manuscript until devices were obtained later in
1849. In the early years, there was no need for cancels because there were no stamps
available to cancel until the United States 1851 issue.
Three useful sources exist for classifying San Francisco postmarks, rate marks and cancels:
- The most comprehensive is Mahoney, John M., San Francisco Postal Markings, _PHONE_,
La Posta Monograph Series, Vol. 8, La Posta Publications, Lake Oswego, Oregon, 1992.
Mahoney's book includes tracings of postmarks, killers, rate marks and other
- Also important is Williams, John H., California Town Postmarks, 1849 - 1935, Western
Cover Society, 1997, published by Leonard H. Hartmann, Louisville, Ky. This book deals
exclusively with postmarks and contains numerous tracings as well.
- Third is an article by Friend, Clifford L., The 26mm Double Circle Postal Marking Of
San Francisco, Western Express, Vol XXV, No. 1, January, 1975, p. 11-18. This article is
limited to the double circle postmark introduced at San Francisco in September, 1861.
Friend's work is built upon earlier studies by Stanley Ashbrook. Neither Mahoney nor
Williams does justice to the several varieties of this postmark. Mahoney lists them all
as type 79. Williams lists five types, SAF 590, 600, 610, 620 and 630 but gives little
help for distinguishing them.
The two books have their strengths and weaknesses. Mahoney covers a broader field, but
in the early postmarks, there are some omissions and some of the usage dates are suspect.
He also uses a single tracing to illustrate several similar but distinct styles,
sometimes leading to confusion. Williams's book is in two large volumes, covering the
entire state. The San Francisco postmarks are found in Volume 2, but the explanation
key for his listings is found only at the start of volume 1, so you need to buy two books
to get the San Francisco postmarks with the key to understanding the listings. Williams
includes multiple tracings of the early San Francisco postmarks and has a tracing for
each style. However, some tracings have no discernible differences from other tracings
and I find the explanations sometimes inadequate for distinguishing them. I use both
books, except for the double circle postmarks, where I use Friend's types because neither
Mahoney nor Williams do justice to those postmarks. In this website, I attempt to give
type references used by each author. Only postmarks found on Hawaiian mail are relevant
to our study here so many postmarks used in San Francisco will be omitted intentionally.
Others may exist but I have not recorded them. Please send me
an E-mail (_EMAIL_) with information about other San Francisco pre-1870 postmarks on covers from
San Francisco postmarks are found on most letters arriving from Hawaii, but in this
Period they are rarely found on letters originating on the mainland unless mailed at San
Francisco. The practice of using postmarks on letters transiting the office was some
years in the future. Mail arriving at San Francisco from Hawaii or other Pacific ports
was first entered into the United States mail at San Francisco so the postmark was used
to indicate where the letter entered, rather than merely as a transit mark.
For ease of loading and access, the San Francisco marks are divided into the following sub-pages:

Control the jade quarries.
- Be the first team to score 10 points, or score more points than your opponent before 15 minutes have elapsed.
- Claim quarries to begin collecting jade.
- Protect your team's jade carriers.
- [No one controls / Kurzicks control / Luxons control] the Green quarry.
- [No one controls / Kurzicks control / Luxons control] the Purple quarry.
- [No one controls / Kurzicks control / Luxons control] the Yellow quarry.
- Imperial faction that is awarded at the end of a match:
- Each team receives 300 for each jade slab collected.
- The winning side receives an additional 1,000.
- Players receive 10 Imperial faction plus 10 Balthazar faction per kill in real time.
The Jade Quarry is a resource control arena that is fought between the Luxons and Kurzicks. There are three resource points known as quarries, from where jade is carried back to the base of Luxons or Kurzicks. Carrying the Jade is done by a Hauler Turtle if the Luxons are in control, or by a Carrier Juggernaut if the Kurzicks are in control.
- The first team to bring ten jade slabs to their base or which has the most jade when the time runs out wins the match.
- Each team consists of eight players that are randomly assembled by those entering from the Jade Quarry (Kurzick) and the Jade Quarry (Luxon) staging areas of all districts.
- The map is balanced so that neither side has an advantage over the other. The three quarries are positioned (and colored) as follows: Purple quarry is closest to the Kurzicks, Green quarry is closest to the Luxons, and Yellow quarry is of equal distance from either side. There are a number of guard posts that are situated on the map which may be taken to hinder the passage of opposing players and carriers.
- All players resurrect automatically in their base and do not receive Death Penalty. Each base has three one way teleporters that are labeled for each quarry. These teleporters will take you to a location that is somewhat close to the quarry for which it is labeled.
Quarries start unclaimed : the first side that gets a player stand on the stone platform gains control. The yellow quarry is the only one which is at the same distance from the two sides. The purple quarry is close to the kurzick base while the green quarry is close to the luxon base.
- Five NPCs protect a quarry: one Ranger (Kurzick Far Shot or Luxon Longbow), two Mesmers (Luxon Wizard or Kurzick Illusionist) and two Elementalists (Luxon Storm Caller or Kurzick Thunder). As long as one of them is alive, the quarry belongs to the faction.
The guard posts start either luxon or kurzick. They are only composed of rangers :
- Two if near enemy base.
- Four if near ally base.
- Three otherwise.
In order to gain control over a quarry or a guard post, NPCs occupying that area must be killed. Then, allied NPCs will spawn and guard that area for your side.
Strategies by objectives
Generally speaking, there are three ways you can help your team to win : capturing (usually by nuking quarriers, guard posts), intercepting (opposing players, carriers), defending (allied NPCs, players).
Capturing quarries and guard posts is vital. Without quarries your team cannot score any point. Killing the defending NPCs (and to a lesser extent jade carriers) should be your team's top priority.
- Always focus on the closest quarry to your base. Purple for Kurzick/Green for Luxons is usually the easiest one to control and the fastest to retake. Ensuring also control of yellow is usually enough to ensure victory.
- Due to the high number of NPCs, their low health and the fact that they are bunched up together, Area of effect (AoE) damage and health degeneration are extremely effective.
- Bear in mind that elemental damage is less efficient against the numerous rangers due to their high armor against it. If you plan on using it anyway, armor-piercing effects such as cracked armor and armor penetration (Air Magic, Earth Magic and Channeling notably) or health degeneration such as burning (Fire Magic notably) can help you kill more easily.
- NPCs will not heal themselves and also not scatter too far from their spot, at least not enough to avoid most of the area of effect damage.
- NPCs at a quarry spawn in a "V" shape. When using area of effect skills, target the central NPC for better efficiency. If already dispersed by previous attacks, they may be arranged differently.
- Against quarries : quarry mesmers can remove enchantments with Drain Enchantment, interrupt spells with Power Spike and interrupt attacks with Clumsiness (usually twice with Echo, so up to 4 times with the two mesmers), while quarry elementalists can inflict a high amount of damage with Air Magic skills and knock down with Lightning Surge. That's why one or two spells will usually be as much as you can cast if engaging the quarry on your own, and any strategy including melee attacks will be very difficult to use.
- Against guard posts :
- If using spells which doesn't require a clean line of sight, hide next to walls with an obstructed line of view so that ranged NPCs won't hit you.
- If possible, try to attack from a higher point than the rangers so that you'll stay out of range of the bow attacks but still be able to attack with range weapons/spells.
- Being primarly composed of rangers, standard PvE farming builds such as those based on Vow of Strength, Hundred Blades, Whirling Defense, Sliver Armor, possibly combined with a shadow step skill such as Death's Charge can allow for a quick capture.
- If possible, kite the rangers' arrows and beware not to get crippled
- Capture guard posts between the quarries and the opposing base, as two rangers are enough to take down a carrier if not hindered.
- If a quarry or a guard post is heavily defended and you and your team are unable to capture it, go to another point to avoid wasting too much time.
- To keep track of your side's status use the U map as it extends enough to see all arena flags.
- Don't attack opposing players unless they are directly impeding your ability to capture a quarry, a guard post or a carrier.
- Shadow step skills can allow you to move regardless of height difference.
- Carriers will not use any skill unless attacked in melee, making them an easy target for skills such as Wastrel's Worry or Wastrel's Demise. They will also always follow the same route, making traps effective in intercepting them. On the contrary, players will not always be able to retaliate if attacked in melee and will usually use skills to escape/heal.
- Carriers and players will almost always be on the move so skills requiring a moving target, such as Melandru's Shot, or more effective against moving foes, such as Lightning Bolt, are very effective.
- Do not kill carriers when they are not holding a jade slab (for example when they are on their way to their quarry to take a new one) and focus on capping the quarry instead, as if you capture the quarry before they reach it they will simply return to base and waste time. If on the contrary they are killed and the quarry is still under opposing control, a new carrier will "spawn" a few moments later at the quarry, making your efforts go to waste.
- Snares, especially crippled, are effective to hinder carriers and players and can give your team a small time advantage to retake a carrier/score more points than the opposing team/kill a carrier holding a jade slab. Knockdowns are valuable against players, since it will slow them down and make them unable to reply to your attacks for a short period of time.
- Shadow Steps skills such as Shadow Prison or Wastrel's Collapse can allow you to quickly get to an unwary player and spike it before it deals any harm to your NPCs or team members. This is especially true for Assassins. Bear however in mind that the player you just killed will be resurrected soon enough.
- Because this is a large map where timing matters, speed boosts are vey valuable to intercept several carriers/players.
- Minions and spirits can be used to bodyblock foes. However, keep in mind that minions are highly vulnerable to Wastrel skills and Ray of Judgment which are very common in the Jade Quarry.
- Focus first on keeping jade carriers safe, as your team will not score if they don't arrive at the base. Escort them on the way back unless you are 100% sure they will not be attacked.
- Ensure quarries and guard posts NPCs stay alive with skills such as Heal Area. At least one must survive for your team to maintain control over the area. Ritualists can use their spirits to bodyblock foes while also protecting the NPCs.
- Even bow users can't reach a character in the back of a quarry, allowing you to heal and protect from a safe location.
- Ensure

19.6 DBMS_LOB Subprograms Used with DBFS
You should note that some changes have been made to the DBMS_LOB subprograms over time.
Table 19-2 summarizes changes made to PL/SQL package DBMS_LOB subprograms.
Be aware that some of the DBMS_LOB operations that existed before Oracle Database 11g Release 2 throw an exception error if the LOB is a DBFS link. To remedy this problem, modify your applications to explicitly replace the DBFS link with a LOB by calling the DBMS_LOB.COPY_FROM_LINK procedure before they make these calls. When the call completes, then the application can move the updated LOB back to DBFS using the DBMS_LOB.MOVE_TO_DBFS_LINK procedure, if necessary.
Other DBMS_LOB operations that existed before Oracle Database 11g Release 2 work transparently if the DBFS Link is in a file system that supports streaming. Note that these operations fail if streaming is either not supported or disabled.
Table 19-2 DBMS_LOB Subprograms
Subprogram Description
Copies an existing DBFS link into a new LOB
Copies the specified LOB data from DBFS HSM Store into the database
Returns a unique file path name for creating a DBFS Link
Returns the DBFS path name for a LOB
Returns the linking state of a LOB
Moves the specified LOB data from the database into DBFS HSM Store
Links a LOB with a DBFS path name

In our post about caring for your guitars, we shared some simple storage and maintenance techniques to ensure that your guitars stay up-to-snuff and playable. However, that's only part of the battle when it comes to studio equipment. In fact, perhaps the most prevalent pieces of equipment are your electronics. These include the audio interface, the speakers, the monitors, your rack gear, your effects processors, your amps, etc. Needless to say, that is a lot of equipment to worry about it. This week, we'll give you some general storage, cleaning and maintenance rules for some of this equipment. You can also check out this article for some general electronics tips.
Much like our discussion on humidity and guitars, the environment is an important consideration for your home studio. In terms of electronics (in any room, not just studios), humidity is often neglected as an important concept. So what are the concerns here? Well, if your humidity is too high, that means that there is a significant amount of water/moisture in the air. Therefore, you run the risk of corrosion on the circuit boards or moving electronic parts. While the risk obviously isn't as extreme as, say, dumping a bottle of water onto your computer, why would you want to leave your electronics in a room with a lot of moisture 24 hours a day?
Of course, keeping the humidity extremely low isn't the answer either. At low humidity levels, the risk of strong static charges increases substantially. This could actually cause certain components in your computer, speakers or rack units to short out or wear more quickly. So, the name of the game here is prevention. Make sure you keep your studio within an ideal humidity range (roughly 30"60% humidity) at all times. While you should be fine within this range, it's often better to be closer to the lower end (30"40%), simply because the risk of static charge is a little less likely/damaging than extended humidity exposure. Keep in mind when using humidifiers or dehumidifiers that humidity levels fluctuate with the seasons (and depending on your location). Keep things within this range, and you'll have a decently safe place to store your gadgets.
Maintenance and Cleaning
We'll close this article with some simple tips to keep your music electronics clean and maintained. In general, it's fairly obvious to make sure your electronics are dust-free as often as you can. While this may seem obvious, it's often neglected. Simply dusting your electronics each day (using a cloth or dust pad), will eliminate a lot of the dust that might get inside of the electronics. If the enclosures are easy to open, you could dust the insides as well, but be wary as there is risk of breakage.
Disclaimer: Don't attempt to open up electronics unless you understand how they work, as there is always a risk of shock. Please follow the manufacturers' warnings.
Finally, a few emergency tips are in order. If you are cleaning your monitors or surfaces with cleaners, be cautious about which ones you use. Many computer monitors can be sensitive to many household cleaners (as can most electronics). Also, be aware of how much pressure you are using to clean monitors, as pressing down too hard can cause indents or even cracking (particularly in LCD screens).
Beyond this, if you've reached the point of no return by either spilling a liquid on your device or you begin to notice an electrical burning smell, turn the device off immediately. While a burning smell can indicate many different things, and we recommend seeking a trained technician, many guitar amps will smell like this if a fuse or tube is overheating. Therefore, turning off the device and letting it cool down may solve the problem. Shutting off a device and letting it dry after spillage can also solve the problem, as water will only cause short-outs if the device is on (in most cases).
Disclaimer (again): Don't open the device and try to fix it if you don't know how to as there as a huge risk of dangerous electric shock. The bottom line: if you are worried, seek a technician's opinion.
Overall, your studio contains a lot of electronics (even the heart of most home studios, the computer itself). So, neglecting to care for these crucial machines can cost you a lot and even prevent usage of your studio.

I need to isolate a word that starts with a hashtag (#) from a string of user input. For example if the user enters "Hi how _TAG_ you today" i need the program to print out "_TAG_".
My thought process was to try to isolate the substring from the index of the # to the next space, but I do not know how to get it to recognize the index of the next space instead of just the first space in the string. So my code for this action looks a little like this right now:
tweet = keyboard.nextLine();
int pos = tweet.indexOf("#");
String hashtag = tweet.substring(pos, " ");
System.out.println("Hashtag: " + hashtag);
ANY advice would be helpful. Also I have not learned about loops or arrays yet so if there is anyway to do this without them that would be great!

How To Find Out Which Proccess is Listening On A Port for Windows?
System or Network administrators looks ports and applications to solve problems. Getting port and application info in Linux can be done lsof command. But in Windows?
netstat is a very popular and useful tool used to get network and port-related information.
List Listening Port with netstat Command
We will use
netstat command like below in order to list which process, application or service listening which port on Windows.
- -a Display all connections and listening ports
- -b Display port and connection related executable/application
- -n Display port numbers as a number, not port name
- -o Display process/executable owner
C:\> netstat -a -b
What is that? it says we need Administrator privileges. Open command prompt with Administrator privileges
From the output following information is provided
- The protocol is the transport layer protocol like TCP or UDP
- Local Address is the current local system IP address.
0.0.0.0means every IP address current system have. Because the current system may have multiple interfaces and IP addresses.
- Foreign Address is the remote system address or Hostname which is connected or waiting
- State specifies the given port status like LISTENIN, CLOSED, CONNECTED etc.

Class: How to write in your siddur
Why use a siddur
1. Talmud Yerushalmi, Berachot 2:4
2. Tosefta Shabbat 13:4
3. Rambam, Mishneh Torah, Hilchot Tefilah 4:19
4. Pri Megadim, Orach Chaim 53 Mishbetzot Zahav 15
5. Shulchan Aruch Orach Chaim 96:2
Our problems: Fixed text; Blob of text; Familiarity
6. Mishnah Berachot 4:4
רבי אליעזר אומר העושה תפלתו קבע אין תפלתו תחנונים
7. Talmud, Bava Batra 164b-165a
8. Rambam, Moreh haNevuchim 3:51
Writing in a siddur?
9. Mishneh Berurah 96:9
10. Shulchan Aruch Orach Chaim 90:23
Practical tips
1. Mark phrases for special concentration
2. Mark structural/poetic elements that provide greater meaning
3. Add wake-up calls
4. Mark lines requiring explanation
5. Write in food for thought
Writing notes
1. Pencil, small marks, change them regularly
2. Spread marks throughout the various prayers
3. Be ready to replace your siddur
4. Don't distract from the davening
 1. Moradik!!!
 Please post the link when this is online (and maybe even the full source sheet).
 2. I use these with my students. _URL_
 Each color flag means something different. Green is congregational singing. Yellow is silent/individual. Red is repeat. You can make notes on the flag without having to write in the siddur itself.
 We also do a lot with post-it notes.
 3. Cool. So you are the one responsible for all the yidden with flags in their siddurim and machzorim.
 Actually I currently use thoses flags to highlight the order of notes that I make in seforim.
 4. One of my first Bar Mitzvah students used my transliterated siddur for his preparation and for the service, and I still have his notes, highlighting, etc. throughout the service. I can't really pray from it anymore because it's distracting, but I love it and it will always be a memento of his Bar Mitzvah. He had post-its and tabs in addition to the notes and highlighting.
 I later started working for a synagogue here that doesn't allow students to make any marks in their books.
 My own siddur has tabs and very light pencil marks.
 5. Left Wing Modern Orthodox: 79%
 Right Wing Modern Orthodox: 75%
 Left Wing Yeshivish/Chareidi: 36%
 Right Wing Yeshivish/Chareidi: 15%
 I don't know why it called me orthodox at all. Maybe because I see the Talmud as a source of value and morality.
 6. Morah BetsyGood system! In this class I'm going for writing to add meaning/inspiration, but that does sound like a good way to handle the basic need for "What am I supposed to be doing here?"
 7. NeilIt's now on-line; I'd love your feedback!
 8. Will listen as I prepare the mashed potatoes in the AM. Thanks!
 9. Interesting.
 I've gone through phases. Depending on different things going on, where I'm holding [as the torah true say], what siddur is my Siddur Du Jour etc.
 First and foremost, again depending on the siddur: marking sheva na/nach and kamatz gadol/katan. That's the first thing I used to do soon as I'd crack the spine.
 In my zealot days, I'd photocopy things missing from the Siddur Du Jour. Anim zemirot from the Siddur HaGra, for instance. Tefillat Leshlom hamedinah missing from almost every siddur.
 I'd photocopy those charts of interruptions, when you can say amen, etc. at which parts of davenen.
 I'd mark things like in Az Yashir, which pesukim are said in the special trop. Mark the trop for the kedushah in yotzer or. I used to be a real zealot.
 Mark certain tefillot where acharonim advise special attention, and the merits of special attention: yehi kavod, aleinu etc.
 Word counts. Word counts in the amidah for each brachah. Numbering shem Hashem in the amidah, or in yehi kavod, or in baruch Hashem or in az yashir etc.
 Marking certain kabbalistic roshei teivot, phrases where the roshei teivot had significance. I was a little kabbalist in my heyday. Marking the 15 vav's for example in emet veyatziv.
 Notes to remember the 6 zechirot in Ahavah Rabbah. Notes to remember the aseret hadibrot in shema.
 Notes for halachic stuff, like not to say the tamid before alot, or hanotein lasechvi vinah.
 There's no end.
 With regard to the comments above about post-it flags, this online shiur about post-its on shabbat might be interesting to some:
 10. Wait, Melech -
 "In your zealot days"? When did those end?
 11. Great stuff, Rabbi.
 I'm curious, though: in the context of your shiur, did you differentiate between doing this as preparation for tefillah vs. during the tefillah itself?
 I used to use an Artscroll siddur until I realized that I was going through the commentary when I was supposed to be davening. That was mussar in itself.
 12. Shmuel, that's why I predict taht after this shur is listened to by the masses, we'll all go out and buy the Birnbaum! It has no commentary and pleny of room to write it.
 It will be a retro revolution!
 13. Shmuel-
 I believe in only minimal notes - underlines, circling, asterisks. Maybe a word or two to hint at a greater idea.
 I do think it's worthwhile to make a note like that during davening (although not the Amidah), if it will enhance the experience.
 14. I finished the shiur tonight and actually went through mussaf for Rosh Chodesh tonight and started underlining certain things. For me it was less daunting to start w/ the amidah then starting at the beginning of the siddur.
 The shiur was great, but please post the link to the "book review lady". I found the suggestions practicle and your "program" really does allow for one to personalize the set tefillos. The actual workshop examples, like "Baruch She'ehmar" and "Ashrei" were helpful.
 Post importantly, just making an attempt to make notes on davening allows me to REALLY take time to read tefillos.
 15. Just finished the shiur tonight.
 I thought it was great, but would like the link for the "book review lady". I actually sat down and went through mussaf for Rosh Chodesh and made a few notes and did some underlining. It seemed less daunting to do this than actually start at the beginning of the siddur (for now).
 I thought the suggestions in the shiur to be practicle and loved the short workshops on "Baruch Sheh'ehmar" and "Ashrei".
 I think think the best part, for me, of attempting to write in my siddur is the fact that I will ACTUALLY have to think about the tefillos.
 16. Hi Neil,
 Thanks for your comments! The book reviewer is in Source 11 on this post.
 17. Thanks. That makes sense, seeing how I listened finished the shiur tonight and saw your sources last week.

The DataWORKS Reading Diagnostic Assessment (RDA) is designed to assess the current reading level of a student based on the five components of literacy:
The Reading Diagnostic Assessment is designed to pinpoint at what grade level students are reading based on their mastery of the content within each literacy component. A student entering a grade should ideally display reading skills typical of the low end of that grade. For example, a student entering first grade should know all of the letter names and sounds of those letters; whereas a student entering fifth grade should be able to read a fifth-grade passage fluently.
But, the reality is that many students are not reading at grade level, so the Reading Diagnostic Assessment allows teachers to pinpoint the areas where further instruction or remediation is required for each student.
See some samples of our Reading Diagnostic Assessments.
The Reading Diagnostic Assessment is available as an online assessment, or it can be downloaded and printed for hand-scoring.
Sample Online Assessment
Sample Printed Assessment
The assessment should be administered multiple times throughout the year. At the beginning of each school year, the assessment should be given to establish a baseline score for each student and to help teachers plan instruction or organize reading groups.
The assessment should then be repeated in the fall and spring to determine how much students have learned and what needs to be reviewed.
Finally, the assessment can be given a final time at the end of the school year to mark the highest level of literacy for that school year. The results from this end-of-year assessment can also be used in place of a baseline test at the beginning of the next school year, if needed.

1 block of fat, protein, and carbs = 91 calories.
1 block of protein is 28 cals
1 block of fat is 27 cals
1 block of carbs is 36 cals
CrossFit uses a.7 as the activity level.

Manual handling is defined as the "transporting or supporting of a load by one or more employees and includes lifting, putting down, pushing, pulling, carrying or moving a load, which by reason of its characteristics or of unfavourable ergonomic conditions involves risks, particularly of back injury, to employees". Because it is a major cause of accidents in workplaces (typically 33% of all workplace accidents annually) it is a priority safety issue.
Legislation was enacted in 1993 and updated in 2005/6 which sets down specific requirements for all forms of manual handling:
* to take appropriate measures to avoid the need for the manual handling of loads by employees;
* where manual handling cannot be avoided, to take appropriate organisational measures, use or provide appropriate means to reduce manual handling risks, eg. provide appropriate equipment, reduce mass of loads, better organisation of storage areas, etc;
* the manual handling risks are to be assessed to identify how best to reduce the risks;
* take appropriate measures to avoid or reduce the risks;
* to provide training for all employees involved in manual handling.
NUI Galway currently have four members of staff who have completed Manual Handling Instructor training;

Introduction: Identifying major bleeding is fundamental to assessing the outcomes of anticoagulation therapy. This drives the need for a credible implementation in automated data for the International Society of Thrombosis and Haemostasis (ISTH) definition of major bleeding. Materials and Methods: We studied 102,395 patients who received 158,511 person-years of warfarin treatment from the Veterans Health Administration (VA) between 10/1/06-9/30/08. We constructed a list of ICD-9-CM codes of "candidate" bleeding events. Each candidate event was identified as a major hemorrhage if it fulfilled one of four criteria: 1) associated with death within 30 days; 2) bleeding in a critical anatomic site; 3) associated with a transfusion; or 4) was coded as the event that precipitated or was responsible for the majority of an inpatient hospitalization. Results: This definition classified 11,240 (15.8%) of 71, 338 candidate events as major hemorrhage. Typically, events more likely to be severe were retained at higher rates than those less likely to be severe. For example, Diverticula of Colon with Hemorrhage (562.12) and Hematuria (599.7) were retained 46% and 4% of the time, respectively. Major, intracranial, and fatal hemorrhage were identified at rates comparable to those found in randomized clinical trials however, higher than those reported in observational studies: 4.73, 1.29, and 0.41 per 100 patient years, respectively. Conclusions: We describe here a workable definition for identifying major hemorrhagic events from large automated datasets. This method of identifying major bleeding may have applications for quality measurement, quality improvement, and comparative effectiveness research.

Create workflow templates, deploy against any entity and manage tasks associated with that entity.
Advvy's Workflow Engine and Task Management solution supercharges new and existing D365 and PowerApps apps with task management capabilities. A major limitation of D365 is that an entity generally can only have 1 business process header, and that business process is generally linear.
Advvy's Workflow Engine enables users to define their own business process - that is a series of Stages, Tasks and Subtasks, and have this workflow template deployed against an entity upon create. Each task can be predefined to be for a User, a role, role speciality and tasks can block tasks and be blocked by tasks. The entity will then have a new Tab called Workflow, and this entity will allow the users of the application to manage the stages and tasks. Tasks can have conditions and dependencies, and can be a trigger for Flow in PowerAutomate. Business processes can be competed either linear or non-linear.

FullContact Developer API Documentation
The FullContact Developer APIs are used to manage and enhance contact information. Use our APIs to provide social profiles in your app, improve contacts in address books, enrich CRM information, or create highly personalized marketing campaigns.
Our APIs are RESTful. Responses are delivered in JSON or XML format. Some endpoints support HTML or vCard formatted responses. Sign up for a free account to get an API Key and get started.
All requests to all endpoints require you to specify your unique API key. The API Key is assigned to you by FullContact and is used to identify and authorize each request. Your API key should be kept private, and should never be displayed publicly.
There are two methods to specify the API key in a request: 1. Specify it using the apiKey= query parameter; 2. specify the API key in the HTTP request header using an extended header field with name X-FullContact-APIKey.
The use of the HTTP header field rather than the apiKey query parameter provides an added level of security. Although we utilize HTTPS to ensure that all requests are encrypted for network transport, there is a possibility that the plain-text URI, with the value of the apiKey, might appear the logs of HTTP servers which process the requests.
Response Codes
All successful responses are returned in JSON, XML, HTML or vCard, depending on the response format you request. On our paid endpoints, such as the Person, Card Reader, and Disposable Email endpoints, only queries that respond with a 200 response code (successfully completed), are counted towards monthly allowances and overages.
Status Code Description
200 OK Your request processed successfully.
202 Accepted Your request is currently being processed. You can check again later to see the request has been processed.
400 Bad Request Your request was malformed.
403 Forbidden Your API key is invalid, missing, or has exceeded its quota. **Paid plans will not receive a 403 response when they exceed their alotted matches. They will only receive a 403 for exceeding rate limit quotas.
404 Not Found This person was searched in the past 24 hours and nothing was found.
405 Method Not Allowed You have queried the API with an unsupported HTTP method. Retry your query with either GET or POST.

422 Invalid Invalid or missing API query parameter.
500 Internal Server Error There was an unexpected error on our server. If you see this please contact
Rate Limiting
All API requests are subject to rate limits that exist independently of your API key's monthly usage allowance. We track rate-limits on a 60-second basis. For example, if your API is subject to a 10/second rate limit, we'll allow you 600 requests per 60 second window. To make it easier for your application to determine if it is being rate-limited, or if it is likely to be in the future, we've added the following HTTP headers to successful responses:
What You Need to Know About Rate Limits by FullContact
Header Name Example Value Description
X-Rate-Limit-Limit 600 The rate limit ceiling for your request
X-Rate-Limit-Remaining 10 The number of requests left in the 60 second window.
X-Rate-Limit-Reset 20 The number of UTC epoch seconds remaining until the 60 second window resets

Verezzi - The "Mad Carts" road
Itinerary Data
Difficulty Easy
Length 3,2 km
Duration 2 h
Elevation Gain 165,7 m
Altitude Difference 138,8 m
Short description of Itinerary
Easy itinerary with a short and panoramic loop recently made accessible and fully signposted by the CAI of Finale Ligure. The path partly follows the route of the old roads used by quarrymen to transport the blocks extracted from the numerous quarries that opened in the Verezzi territory towards Borgio. For this purpose, special wagons were used, called "Matti" (Mad) for their particular shape, from which the itinerary takes its name. It is also worth visiting the Cava Vecchia, one of the few quarries in Finale Stone cultivated in a tunnel and the Grotta dell'Antenna (Aerial cave) with its unique lock shaped entrance.
The "Mad Carts"
For the transport of the blocks extracted from the quarries to the "Marina di Verezzi", wooden wagons pulled by oxen or mules were used. These carts were.....
Verezzi Stone
The Verezzi Stone (or rose marble of Verezzi or Pietra Lara) is a reddish variant of Finale stone. It originated from the compaction of sands and calcareous parts of crustaceans, shells, sea urchins.....

Upgrade Issues
Priority Paging Is Not Needed With the New Solaris 8 Caching Architecture
The Solaris 8 operating environment introduces a new file system caching architecture, which subsumes the Solaris 7 Priority Paging functionality. You should not set the system variable priority_paging in the Solaris 8 operating environment, and you should remove the variable from the /etc/system file when systems are upgraded to the Solaris 8 operating environment.
The new caching architecture removes most of the pressure on the virtual memory system that resulted from file system activity. As a result, the new caching architecture changes the dynamics of the memory paging statistics, which makes observing system memory characteristics simpler. However, several of the statistics report significantly different values. You should consider these differences when analyzing memory behavior or setting performance monitoring thresholds. The most notable differences are:

The engineer is key to helping artists and producers realise the sounds they desire. Drawing on the skills and techniques they have acquired allows them to shape and bend the performance into a polished musical statement.
In The Studio
I have spent a considerable amount of time in the studio environment, heading recording sessions, mixing tracks and editing audio files. These experiences have left me with a great proficiency in operating a number of audio tools, both analogue and digital.
On Location
Being able to work outside of a controlled studio environment requires thorough preparation, strong perception of a space's acoustic qualities and detailed knowledge of microphone technique.
Audio Restoration
Even with the best equipment, positioning and acoustics, unwanted noise can still creep onto a recording. In these situations the use of specialised software can remove microphone hiss, environmental bleed and noises made by the performer. The examples below illustrate what can be achieved in noise reduction and restoration; spectrogram results show the intensity of sound as low/dark blue to high/bright orange.

McGowan Institute for Regenerative Medicine
affiliated faculty member Philip LeDuc, PhD (pictured), Carnegie Mellon University (CMU) professor of mechanical engineering, and Mary Beth Wilson, a CMU PhD candidate in biomedical engineering, have won an extremely competitive Grand Challenges Explorations Award from the Bill & Melinda Gates Foundation to explore nutrition for healthy growth of infants and children in underdeveloped countries.
"What we are doing is studying how to alter a plant's cellular and molecular structures to optimize release of nutrients during digestion," said Dr. LeDuc, who has courtesy appointments in the Biomedical Engineering, Biological Sciences and Computational Biology departments at CMU. "The idea originated when we became interested in how structural mechanics affect the taste of food. We built off this idea in thinking about how we could apply it in an innovative and meaningful way to tackle global challenges especially for the health of children in poor regions of the world."
Both Dr. LeDuc and Ms. Wilson believe that generating widespread acceptance and consumption of nutrient rich plants like African leafy vegetables could significantly improve infant and child nutrition while curbing rising food costs. Global food prices hit record highs in February 2011 and are expected to become even more volatile. The United Nations reports that more than 900 million people in the world suffer from hunger on a daily basis.
"We have chosen to focus initially on amaranth, a plant indigenous to Sub-Saharan Africa, due to its high content of provitamin A and other micronutrients. We hope that integrating amaranth leaves into feeding strategies as infants transition from breast milk to solid foods could contribute to a reduction in vitamin A deficiency," said Ms. Wilson, a CMU Dowd-ICES (Institute for Complex Engineered Systems) fellow from Bridgeport, WV.
Dr. LeDuc said the work involves significantly changing the palatability of the end food product. "These African leafy vegetables are perceived as 'poor man's food' with a bitter taste," Dr. LeDuc said. "We aim to change both taste and perception by reengineering the plant's cellular structure using traditional principles of cell mechanics that have been used for decades in areas such as heart disease and cancer."
CMU researchers say they also are tapping into the modern and cutting-edge methodology of "molecular gastronomy," the study of physical and chemical processes that occur while cooking. Their culinary curiosity will be showcased next year in a new academic course titled "Culinary Mechanics," designed to explore the application of engineering principles to the science of food.

ingredients & lore
blended with decaf ceylon tea, natural peach flavor, marigold flowers, apple pieces and apricots
Cultivation of peaches began in China as early as 2000BC. The winds of trade brought peaches to Greece and Persia, where they were instantly accepted. The juicy fruit was also a big hit with the Romans, who cultivated it throughout the empire. From Italy, peaches made the leap across the Atlantic, where early settlers planted them throughout the East Coast. Soon they were so plentiful, local botanists thought of them as native fruits.

There is a widespread misunderstanding that radiation therapy as a treatment for localized prostate cancer will allow the patient to have or recover normal ejaculatory function after treatment. Let us be very clear that this is not usually the case at all.
A new study by Sullivan et al. has helped to confirm the accuracy of this statement.
Within the Sexual and Reproductive Medicine Program, which is part of the Urology Service at Memorial Sloan-Kettering Cancer Center (MSKCC) in New York of the sexual health evaluation for post-RT patients, men are routinely evaluated after their treatment for localized prostate cancer and are provided with information regarding their ejaculatory function and orgasm.
Sullivan et al. carried out an analysis of their database in which they excluded all men with a prior history of radical prostatectomy, cryotherapy, focal therapies, and androgen deprivation therapy (ADT). In other words, they isolated the patients who were treated with some forms of radiation therapy.
Here are the results of their analysis:
- The basic data included 364 consecutive patients.
- 252/364 patients (69.2 percent) had been treated with external beam radiation therapy (EBRT)
- 112/264 patients 30.8 percent) had received brachytherapy (BT).
- The average (mean) age of the patients was 64 ± 11 years (range, 42 to 78 years).
- The mean follow-up after RT was 6 ± 4.5 years.
- The mean prostate size at time of radiation therapy was 42 ± 21 g.
- 262/364 patients (72 percent) had lost the ability to ejaculate in an antegrade fashion after prostate radiation therapy by the time of their last visit to the sexual and reproductive medicine clinic.
- 16 percent had experienced anejaculation at 1 year post-therapy.
- 69 percent had experienced anejaculation at 2 years post-therapy.
- 89 percent had experienced anejaculation at 3 years post-therapy.
- For men completing at least two International Index of Erectile Function (IIEF) questionnaires, orgasm domain scores (which range from 0 to 10) decreased dramatically over the follow-up period.
- At < 12 months post-therapy, the orgasm domain score averaged 7.4.
- At 13 to 24 months post-therapy it averaged 5.4.
- At 25 to 36 months post-therapy it averaged 3.2.
- At >36 months post-therapy it averaged 2.8.
- Factors predictive of anejaculatory status included older age, concomittant ADT, radiotherapy dose > 100 Gy, and smaller prostates at the time of radiation therapy.
Sullivan et al. conclude that "The vast majority of men after prostate [radiation therapy] will experience anejaculation and should be counseled accordingly prior to undergoing therapy."
Many patients are apparently under the impression that radiation therapy only affects the cancerous cells in their prostates and that the normal ("healthy") cells will be unaffected by radiation therapy. This is simply not the case.
Radiation of the prostate is designed to kill all cells in the gland if at all possible. It therefore has the same effect on the functioning of the prostate as radical surgery because (to all intents and purposes) there should be no living prostate tissue a year after the radiation is complete. The reason that there almost always is a small amount of living prostate tissue is that the radiation commonly does not, in fact, kill all of the normal prostate cells, which is also why PSA levels do rise slightly after first-line radiation therapy and don't drop to undetectable levels. However, the amount of living prostate tissue that remains is normally far too small to permit normal ejaculatory function and normal orgasmic function.

The Wheat Data Interoperability Working Group (WDI) was created within the framework of the Research Data Alliance (RDA). The RDA is a global initiative that aims to foster the open sharing of data across technologies, disciplines, and countries to address society's major challenges.
The WDI's goal is to provide a common, open-standard framework for describing, representing, linking, and publishing wheat data. Here, we present the case for establishing the Wheat Data Interoperability Guidelines, which will promote and sustain wheat data sharing, reusability, and interoperability. We have decided to focus on a limited set of wheat data types: SNPs, genomic annotations, phenotypes, genetic maps, physical maps, and germplasm.
The Wheat Data Interoperability Guidelines will have a threefold impact. They will:
- Promote the adoption of common standards, vocabularies, and best practices for wheat data management.
- Facilitate access to as well as discovery and reuse of wheat data.
- Facilitate wheat data integration.
We conducted a survey from April 7 to June 3, 2014, to identify existing data management practices within the wheat community. We received replies from 196 individuals in at least 31 different countries. Our preliminary analysis of the results tends to confirm the need for a framework and guidelines for wheat data management:
- Most of the respondents (114) currently store their data on local drives, but the majority of them (84) are willing to use shared databases and repositories.
- More than 50% of the respondents have not yet established data management guidelines.
- When asked which data types will be the most important over the next five years, the majority of the respondents listed the same categories that we had chosen (i.e., phenotypes, SNPs, genomic annotations, germplasm, genetic maps, and physical maps). Only 24 of the 196 respondents mentioned other data types.
- In addition to using a variety of data types, the wheat community also employs a wide range of data formats (standardized and unstandardized). For some data types, like phenotypes, the data format used is inconsistent. Hence, we view this situation as an opportunity for standardization and harmonization.
- The use of ontologies and metadata standards is not common. Only 49% of the respondents are currently using ontologies, and only 23% are using metadata standards. Most of the respondents do not see how such standards could be beneficial, and some evoke the lack of implementation and/or standardization as their reason for not conforming to a standard themselves. This underscores the need to highlight the advantages of common vocabularies and metadata standards for wheat data description and representation.
The next steps will consist of:
- Discussing these issues with wheat data experts: the goal is to a) identify the minimum set of properties that should characterize datasets of each data type to ensure meaningful data sharing, b) identify the gaps in standards that remain to be filled, and c) come up with recommendations for data formats and metadata standards. We are planning to hold a 1-2 day workshop with wheat data experts before the end of October.
- Writing a cookbook that will provide guidelines for wheat data description and representation. We will base our methodology on that used by the FAO used to create the LODE cookbook.
The benefits expected from the Wheat Data Interoperability Guidelines are the following:
- Wheat data managers and data scientists will have a common and global framework with which to describe, document, and structure their data.
- Researchers, growers, breeders, and other data users will be able to seamlessly access, use, and reuse a wide range of wheat data. Data linking will also facilitate the development of new data analyses and knowledge discovery methodologies.
- Data managers and scientists focused on other plant species will be able to benefit from the reusable data framework we have established.
- Researchers working on other plant species will be able to more easily access and reuse wheat data and forge links with their own data.
The cookbook could potentially be adapted for use with other crops, such as rice and maize, which are also very important for food security.

Black Elk Speaks: Being the Life Story of a Holy Man of the Oglala Sioux
The most famous Native American book ever written, "Black Elk Speaks" is the acclaimed story of Lakota visionary and healer Nicholas Black Elk (1863... Show synopsis The most famous Native American book ever written, "Black Elk Speaks" is the acclaimed story of Lakota visionary and healer Nicholas Black Elk (_PHONE_) and his people during the momentous, twilight years of the nineteenth century. Black Elk grew up in a time when white settlers were invading the Lakotas' homeland, decimating buffalo herds and threatening to extinguish their way of life. Black Elk and other Lakotas fought back, a dogged resistance that resulted in a remarkable victory at the Little Bighorn and an unspeakable tragedy at Wounded Knee. Beautifully told through the celebrated poet and writer John G. Neihardt, "Black Elk Speaks" offers much more than a life story. Black Elk's profound and arresting religious visions of the unity of humanity and the world around him have transformed his account into a venerated spiritual classic. Whether appreciated as a collaborative autobiography, a history of a Native American nation, or an enduring spiritual testament for all humankind, "Black Elk Speaks" is unforgettable. This special edition features all three prefaces to "Black Elk Speaks" that John G. Neihardt wrote at different points in his life, a map of Black Elk's world, a reset text with Lakota words reproduced using the latest orthographic standards, and color paintings by Lakota artist Standing Bear that have not been widely available for decades.

Using message id headers to determine if an email has been forged
According to the RFCs for email, RFC 822 and RFC 2822, every email should have a message id field that: "provides a unique message identifier that refers to a particular version of a particular message. The uniqueness of the message identifier is guaranteed by the host that generates it.... This message identifier is intended to be machine readable and not necessarily meaningful to humans. A message identifier pertains to exactly one instantiation of a particular message; subsequent revisions to the message each receive new message identifiers."
The message id headers can prove useful when trying to determine if a email is authentic. Although they can't always prove that message is authentic, they can often show that a message has been forged.
Repeated Message ID
In this case, the forger, when creating a fake email, reuses the headers belonging to an earlier message. The examiner need only compare the Message-ID from the email in question to all of the other email messages in the world. Ok, probably not all of the other email messages out there. Usually just the messages on the systems in question are good enough. But finding the same message id on the "smoking gun" email and an old guacamole recipe can be used as evidence that a message was forged.
Impossible Message ID
This case is more subtle, but can be used quite effectively. Although the RFC states that the message id should be globally unique, it says nothing about how it should be constructed. Most email programs have their own format for generating the message id. For example, Apple Mail uses a Universally Unique Identifier and the sender's domain. Thunderbird, on the other hand, uses a combination of the time the message was sent, a salt, and the sender's domain.
Sample Apple Mail Message ID:
Sample Thunderbird Message ID:
If a message was purportedly sent by a certain email program but does not have a message id created by that program, it has obviously been forged. It would be like a round cookie-cutter making square holes; it just can't happen. Thus, if somebody claims that they received an authentic email, look at the message-id and the format of the headers. If the message id does not match the format for that program, the message has been forged!

How to Care for Cantera Stone Fountains
The word "cantera" refers to a form of volcanic stone quarried throughout Central America and Mexico. Cantera is widely regarded for its texture, color and durability. Those attributes and its relative softness make it ideal for carving, shaping and adding aesthetic appeal to home and garden accoutrements, such as decorative tile, fireplaces and fountains. Although the elements of your environment, such as hard water and organic debris, may make caring for a cantera fountain a perpetual endeavor, the methods required for its care are simple.
Check the cantera fountain every day for debris, and remove the debris with a handheld skimmer. You can reserve organic matter, such as brown leaves, and add them to your compost.
Drain your fountain monthly by first turning it off and unplugging it. Open the fountain's drain valve, collect the draining water in a bucket and discard that water. Spray the fountain basin with a water hose while the drain valve is open to remove loose debris, allowing the water to collect in the bucket for disposal.
Turn off and unplug the fountain's water pump. Remove the pump, and open its air pressure valve to release air in the lines. Connect the water hose to the pump's air-flow valve port, and set the filter to "Backwash." Turn on the water running to the hose so that it runs at the highest level, turn on the filter and allow it to run four to five minutes. Turn the water off, remove the hose, close the air pressure valve and turn off the filter. Set the filter from "Backwash" to "Filter."
Mix together 1 tablespoon of mild dish detergent with 1 quart of tepid water in a clean bucket. Lather the basin with that detergent-water mixture using a soft-bristled nylon brush, making sure the lather enters the cantera stone's crevices and pores. Use a circular motion to scrub the fountain's basin and exterior with the nylon brush. Rinse the basin and exterior with cool water from the water hose.
Mix 3 cups of tepid water and 1 cup of distilled vinegar in a plastic food-storage container to create an algae inhibitor. Saturate a sponge in the solution, and apply it to the basin's interior. Allow the solution to dry in the basin.
Saturate paper towels with commercial limescale remover or undiluted distilled vinegar, and use the paper towels to apply the limescale remover or vinegar to water deposits in the basin. Allow them to sit on the deposits for five minutes, and then wipe the deposits with a moist sponge. Fill the fountain to its fill line, and put the water pump back in place.
Drain the water, dry the fountain and cover it with a vinyl cover prior to periods of frost.

Part 4: Commonly Asked Questions about Playing Videos
Apart from learning how to play WMV on Mac and other video formats, users also have several other questions as well. To help you open MKV/FLV files on your system without any trouble, I have further tried to answer these commonly asked queries.
1. What is a WMV file?
WMV, which stands for Windows Media Video, is a compressed video file format that has been developed by Microsoft. It uses the ASF format to compress files and can contain both videos and audios. Apart from online videos, WMV is also used to store DVD and Blu-ray discs as well.
- How do I convert a WMV file to play on a Mac?
Since it is tough to play WMV on Mac, most of the users prefer converting the files to a compatible format. As stated above, you can do this by using a reliable third-party application like Wondershare UniConverter or even try a freely available tool like VLC Media Player.
- Can VLC play WMV on Mac?
Although VLC supports some components of the WMV container, it can't play all kinds of WMV files on a Mac. That is why it is recommended to convert the file to a compatible format like FLV or AVI to play WMV on Mac.
- Can QuickTime open WMV files?
Unfortunately, QuickTime can't be used to play WMV files on Mac since the video container is a propriety product of Microsoft. While the WMV format is readily supported on Windows systems, it is presently not supported in the macOS ecosystem and thus can't be played on QuickTime.
WMV videos can be repaired. Check solutions - Repair WMV Video.

I was worried that a discussion of hair gel would have a certain bias toward men, but my wife assures me that women are just as likely to use a leave-in hair product. I'm going to rely on that unstatistical assurance and roll right on.
We want to consider two tasks: putting hair gel in and taking it out. The first case is easier, so let's tackle that right away. You get some gel, smear it around on your hands, and then give yourself a head massage with those gelly hands. (Better smear it around your hands first, for quicker homogenous application.) So that's it, the gel gets on your hair, and all would be 'cut-and-dry' so to speak, except that your hands still have a bunch of gel on them. In fact, you can rub your hands on your hair for quite a while and you still won't get all the gel off … and that is genuinely interesting in a statistical physics context. In essence, you have established an equilibrium between the gel in your hair and the gel on your hands. OK, now wash your hands, and keep reading.
Let's imagine you arrive at work and decide you look a little too much like John Travolta astride Greased Lightnin' and not enough like a scientist. Time to get rid of some of that gel. We can think of a few ways to get the hair gel out of your hair. One is to take a shower. Another would be to stick your head in the sink under running water (but don't bump your head).
But you can get out that excess gel and avoid bumps and splashing by thinking statistically. Recall our observation about putting in hair gel: some of it stays on your hands, in an effective equilibrium with the gel in your hair. So you can use the principle underlying that observation to remove gel. Put your clean (maybe wet) hands in your hair and rub them around to establish an equilibrium. Some of the gel is on your hands. Wash it off and repeat til you transform yourself back to a respectable nerd.
For those of you in the business, the analogy to protein-ligand binding is obvious. Your hair is like a set of proteins and the gel represents ligands (ions, small molecules or other proteins). Maybe your hands are the proteins' environment. Allow ligands to interact with proteins and they will reach a binding equilibrium. But we can stretch the analogy a step further to invoke signaling in the cell. Say a burst of calcium ions is released in the cell in response to a biological signal and the ions bind to calcium-receptor proteins. We can imagine the signal can be reversed (the hair gel removed) if the unbound calcium concentration is reduced (you rub clean hands in your hair): the equilibrium between proteins and ions will re-adjust due to constant binding/unbinding events. Eventually, almost all the proteins will lose their calcium ions as the signal is removed – from John Travolta to nerd.
Lesson: Look for statistical physics in the world around you – it's better than texting while walking.

What are homosporous and heterosporous plants?
Certain plants are considered to be homosporous and heterosporous plants. Homo-sporous plants produce only one type of spore; heterosporous plants produce or have two types of spores (microspores and megaspores) that develop into the male gametophyte and female gametophyte respectively. (The gametophyte is the phase that produces the sexual organs of a plant; for more about gametophytes, see above.)

The Round Table
For centuries the site of the Roman amphitheatre in Caerleon was known as 'King Arthur's Round Table'.
Back in the 1587 Thomas Churchyard wrote of Caerleon:
In Arthur's tyme, a table round,
Was whereat he sate:
As yet a plot of goodly ground,
Sets forth that rare estate...
It would surely have been an excellent place for a leader to address his followers.
Our theory is that somewhere in time the meaning shifted from 'a round meeting place' to a 'round table'.

The tank winding machine is a high-tech composite pipe product with independent intellectual property rights, world leading level, green environmental protection, energy saving and consumption reduction. The can winder is mainly used as a buried drainage pipe, which integrates the rigidity of the steel strip and the corrosion resistance of the polyethylene, low frictional resistance and wear resistance. As the main product of our company, the tank winding machine is sold well at home and abroad, and has been widely used in key projects such as municipal engineering and sewage treatment plants. So do you really understand the HDPE spiral tanks machine? The following article gives you a brief introduction to the correct use of the can winder, its use, and so on. I hope to help you better understand the tank winding machine.
The main points are as follows:
- What is the HDPE spiral tanks machine
- How to use the fuel tank winding machine correctly
- Use of the machine
- In conclusion
What is the tank winding machine
A tank winding machine is a machine that winds a linear object onto a specific workpiece. It is a new type of machine that has been developed in recent years. In order to meet the requirements of high efficiency and high output, fully automatic models generally adopt multi-head linkage design. Most domestic manufacturers refer to imported models from Taiwan and other places. The design uses a programmable controller as the control core of the device, and cooperates with the robot, pneumatic control components and execution accessories to complete the functions of automatic cable arranging, automatic tangling, automatic thread trimming, automatic loading and unloading of the skeleton, etc. Extremely high, greatly reducing the dependence on labor, an operating staff can look after several such equipment at the same time, the production quality is relatively stable, very suitable for processing applications with high production requirements.
How to control the fuel tank winding machine
The tank winding machine not only has precise mechanical components, but also a powerful electrical control system, which integrates electrical control, sensing technology, mechanical transmission, pneumatic devices and other components. The debugging method is more complicated and finer than other electrical processing equipment. More, the following is a brief introduction to the commissioning of the can winding machine, I hope to help everyone.
① Setting of winding position
What is the winding position? Simply speaking, it is the starting point of the winding on the skeleton. This position is closely related to the coil's head and coil type. It can usually be measured by the measuring function of the equipment control system. The specific value of the position; the operator can also measure manually, using the fixed point as the reference point to actually measure with the ruler, and pay attention to the winding direction of the coil when setting this point.
② The enameled wire specification setting
Our common enameled wire has different wire diameters. The correct setting of the enameled wire line will directly affect the effect of the wire. The enameled wire with different materials needs to be added with different wire diameter correction values. The copper wire is not easy to be thinned, and the correction value is added. The aluminum wire of about 0.02 is easily stretched after passing through the tension of the winding device and the wire passing device, and the correction value is larger than 0.02-0.2.
③ The setting of the winding width
The definition of the winding width is the distance from the position where the winding starts to the end position of the winding. Usually, this value directly reflects the length of the winding that the skeleton needs to be wound. When setting, it is necessary to consider the small deformation amount of the skeleton to be used. The effect of the comprehensive measurement method should be taken as the winding width.
Use of the machine
① Widely used in glass products, hardware tools, electronics, electrical appliances, paper, ceramics, chemicals, food, beverages, building materials, etc., HDPE / PP spiral wound cans for palletized goods (eg: using F bulk goods) Container shipping and packaging with bulk pallets can increase logistics efficiency and reduce losses during shipping. It has the advantages of dust, moisture and low packaging costs.
② Suitable for sealed packaging of F-shaped cylindrical products. Suitable for HDPE / PP spiral wound cans in paper, cord fabric, non-woven fabrics and other industries. The rotary table rotates to drive the cylindrical whole rotating goods, and the two power idlers on the turntable drive the white rotation of the cylindrical articles, thereby realizing the winding machine for fully enclosed winding and packaging goods, which can improve the logistics efficiency and reduce the loading process. loss. It has good dust and moisturizing effects.
③ HDPE spiral can machine for paper making, cord fabric, non-woven fabric and other industries, which drives the white rotation of the drum-shaped article through two power idlers on the turntable, and then realizes the winding machine to be wrapped with a radial cylindrical surface. It is suitable for spirally wrapping the circular surface of the drum-like object. It can improve the efficiency of logistics, reduce the loss during the loading process, and has the advantages of dustproof, moisture-proof and low packaging cost.
④ The plastic winding, aluminum profile, sheet, pipe, dyeing and textile industry, the can winder, refers to the rotation of the goods moving evenly on the horizontal plane through the rotating arm system, while adjusting the expansion force of the package. The material is wrapped into a solid whole by a stretching mechanism, and a spiral regular packaging winder is formed on the surface of the object, which can improve packaging efficiency and reduce the loading process. It has the advantages of dust, moisture and low packaging costs.
The above is the role of the tank winding machine in various fields.
In addition, the market development prospects of tank winding machine are also favored by all walks of life. As packaging machinery manufacturers increasingly focus on developing fast, low-cost packaging equipment, equipment is small, flexible, versatile, and efficient. The HDPE spiral tanks machine market is receiving more and more attention in actual production. This trend also includes saving time and reducing costs. Therefore, the packaging industry is pursuing simple and mobile packaging equipment. Our company's tank winding machines and other programs are widely used for automated operation. If you need a suitable tank winder, please consider us.

How to surprise a copepod: Strike kinematics reduce hydrodynamic disturbance and increase stealth of suction-feeding fish
Limnol. Oceanogr., 54(6), 2009, 2201-2212 | DOI: 10.4319/lo.2009.54.6.2201
ABSTRACT: To capture prey with suction, fish must get sufficiently close to their prey to allow the suction flow to overwhelm the prey and draw it into the mouth. Both swimming towards the prey and suction flow create a hydrodynamic disturbance, which can elicit an escape response by the prey. Using particle image velocimetry, we measured flow speeds and derived fluid deformation rates at the location of the prey as bluegill sunfish fed. In front of the mouth, flows had a composite time-dependent nature. First, the bow wave pushed water away from the fish, but when the mouth opened and suction commenced, flow reversed and water deformation rates increased rapidly. Our inferences indicate that, at the prey, the approaching bluegill is detected primarily based on its suction-induced disturbance, rather than its bow wave-induced disturbance. A comparison of suction-induced disturbance with the signal produced by active suspension feeders indicated that fish are able to produce a more subtle disturbance than expected based on their flow speeds and mouth size alone. Jaw protrusion and the rapid opening of the mouth during the strike both help to minimize the signal available to the prey. We propose that the temporally quick strikes and high jaw protrusion that are seen in many zooplanktivorous teleosts represent adaptations that minimize the time available to prey for executing an escape response.
