emguy.atom('C1') in rings[0])
>>> print('C6', 'C1') in rings[0])
There are a couple of predicates on rings:
>>> print(rings[0].is_aromatic)
>>> print(rings[-1].is_aromatic)
>>> print(rings[0].is_fused)
>>> print(rings[-1].is_fused)
>>> print(rings[0].is_fully_conjugated)
>>> print(rings[-1].is_fully_conjugated)
The predicate 'is_fully_conjugated' is true for aromatic ring systems and for ring systems where every single bond is conjugated, for example the 5-membered ring in 'POCTOS'.
POCTOS 2D diagram
POCTOS 2D diagram to exemplify conjugated rings.
>>> poctos = csd.molecule('POCTOS').components[0]
>>> poctos_rings = poctos.rings
>>> print(poctos_rings[0].is_aromatic)
>>> print(poctos.rings[0].is_fully_conjugated)
The atom 'C6' in 'CEMGUY' is a spiro atom and is in two rings; the atom 'C5' is not spiro but is also in two rings. The Atom property, rings, gives access to the list of all rings in which the atom lies, and the Bond property, rings, similarly gives access to the rings of which the bond forms part:
>>> print(cemguy.atom('C6').is_spiro)
>>> print(len(cemguy.atom('C6').rings))
>>> print(cemguy.atom('C5').is_spiro)
>>> print(cemguy.atom('C5').rings)
[Atom(...)-Atom(...)-Atom(...), Atom(...)-Atom(...)-Atom(...)-Atom(...)-Atom(...)]
>>> print(cemguy.atom('C12').rings)
>>> print(len('C1', 'C5').rings))
Some of the bonds of 'POCTOS' are conjugated:
>>>'C6', 'C7').is_conjugated
>>>'C1', 'O1').is_conjugated
We are not analysing the geometry of the bonded system in order to determine conjugation: this may produce false positives.
Working with string representations of mol2 and sdf files
It is sometimes useful to have access to a string representation of a molecule within a Python script, for example to convert a CCDC molecule into an RDKit molecule by making use of a SDF formatted string as an intermediate.
The ccdc.molecule.Molecule.to_string() method is therefore provided for a molecule to be returned as a string in either 'mol2' or 'sdf' file format.
>>> s = mol.to_string(format='mol2')
>>> print(s)
 39 41 2 0 0
Generated from the CSD
 1 O1 1.9287 5.1676 1.7209 O.2 1 RES1 0.0000
Similarly the ccdc.molecule.Molecule.from_string() method reads in a molecule from a 'mol2', 'sdf', 'mol', or 'cif' formatted string.
>>> m = Molecule.from_string(s, format='mol2')
>>> print('Identifier: %s, Mol.Wt: %.4f' % (m.identifier, m.molecular_weight))
Identifier: ABEBUF, Mol.Wt: _PHONE_
The format parameter may be one of 'mol2', 'sdf', 'mol', or 'cif'.
A SMILES representation of the molecule is accessible through its ccdc.molecule.Molecule.smiles attribute.
Close Contacts
Close contacts, pairs of atoms closer than the sum of there Van der Waals radii, can be identified within a molecule.
>>> abelup = csd.molecule('ABELUP')
>>> print(abelup.contacts())
(Contact(Atom(O1)-Atom(O2)), Contact(Atom(O1)-Atom(O7)), Contact(Atom(O3)-Atom(H2)), Contact(Atom(O4)-Atom(H2)), Contact(Atom(O5)-Atom(H3)), Contact(Atom(O6)-Atom(H3)), Contact(Atom(O7)-Atom(H1)), Contact(Atom(C7)-Atom(H1)), Contact(Atom(O11)-Atom(C9)), Contact(Atom(O11)-Atom(H6)), Contact(Atom(O11)-Atom(H17)), Contact(Atom(C17)-Atom(H6)), Contact(Atom(H5)-Atom(H16)))
The ccdc.molecule.Molecule.Contact instance has a couple of useful properties:
>>> contact = abelup.contacts()[0]
>>> print(contact.atoms)
(Atom(O1), Atom(O2))
>>> print(round(contact.length, 3))
>>> print(round(contact.strength, 3))
>>> print(contact.type)
Van der Waals
Hydrogen Bonds
The hydrogen bonds of the molecule may be obtained by the method ccdc.molecule.Molecule.hbonds().
>>> hbonds = abelup.hbonds()
>>> print(len(hbonds))
>>> print(hbonds)
There is only one hydrogen bond detected. This is an instance of ccdc.molecule.Molecule.HBond which is a derived class from ccdc.molecule.Molecule.Contact and has some additional properties:
>>> hb = hbonds[0]
>>> print(hb.atoms)
(Atom(O7), Atom(H1), Atom(O1))
>>> print('D-H-A: %.3f, H-A: %.3f, D-A: %.3f, Strength: %.3f' % (hb.angle, hb.length, hb.da_distance, hb.strength))
D-H-A: 146.797, H-A: 1.612, D-A: 2.438, Strength: 1.612
HBond Criterion
There is another possible hydrogen bond in this structure between atoms O1 and O2. There is, though, no hydrogen to be donated, but use of the keywork argument 'hbond_criterion' to ccdc.molecule.Molecule.hbonds() will allow this case to be detected:
>>> criterion = Molecule.HBondCriterion()
>>> hbonds = abelup.hbonds(hbond_criterion=criterion)
>>> print(hbonds)
(HBond(Atom(O1)-Atom(O2)), HBond(Atom(O1)-Atom(O7)))
The default constructed ccdc.molecule.Molecule.HBondCriterion does not require the hydrogens to be present, and in consequence both potential hydrogen bonds are detected. Note that the hydrogen bonds returned do not contain a hydrogen even though it is present in one of the hydrogen bonds. In consequence the ccdc.molecule.Molecule.HBond.length and ccdc.molecule.Molecule.HBond.angle are both None.
Let us look more closely at the ccdc.molecule.Molecule.HBondCriterion class. We can retrieve the default behaviour of the method by setting the attribute ccdc.molecule.Molecule.HBondCriterion.require_hydrogens to True:
>>> criterion.require_hydrogens = True
>>> print(abelup.hbonds(hbond_criterion=criterion))
We can specify the geometry of the hydrogen bonds detected:
>>> abacuf = csd.molecule('ABACUF01')
>>> hbonds = abacuf.hbonds(hbond_criterion=criterion)
>>> print(hbonds)
(HBond(Atom(O2)-Atom(H7A)-Atom(O8A)), HBond(Atom(O6)-Atom(H5A)-Atom(O7A)), HBond(Atom(O2A)-Atom(H7)-Atom(O8)), HBond(Atom(O6A)-Atom(H5)-Atom(O7)))
>>> print([round(hb.angle, 3) for hb in hbonds])
[147.972, 160.882, 147.972, 160.882]
>>> print([round(hb.da_distance, 3) for hb in hbonds])
[2.788, 2.879, 2.788, 2.879]
>>> criterion.angle_tolerance = 150.0
>>> hbonds = abacuf.hbonds(hbond_criterion=criterion)
>>> print(hbonds)
(HBond(Atom(O6)-Atom(H5A)-Atom(O7A)), HBond(Atom(O6A)-Atom(H5)-Atom(O7)))
[160.882, 160.882]
>>> criterion.angle_tolerance = 120.0
>>> criterion.distance_range = (-5.0, -0.67)
>>> hbonds = abacuf.hbonds(hbond_criterion=criterion)
>>> print(hbonds)
(HBond(Atom(O2)-Atom(H7A)-Atom(O8A)), HBond(Atom(O2A)-Atom(H7)-Atom(O8)))
[2.788, 2.788]
If we wish we can work with distances, rather than Van der Waals corrected distances:
>>> criterion = Molecule.HBondCriterion()
>>> criterion.vdw_corrected = False
>>> print(criterion.distance_range)
(-5.0, 0.0)
>>> criterion.distance_range = (0, 2.8)
>>> hbonds = abacuf.hbonds(hbond_criterion=criterion)
>>> print(hbonds)
(HBond(Atom(O2)-Atom(O8A)), HBond(Atom(O2A)-Atom(O8)))
[2.788, 2.788]

The reason for using a hood is to block light rays from elements outside of the actual frame (stray light) to enter into the lens and degrade the image quality (lowering contrast). Effectively, it "shades" the lens from these rays. Since a sensor is rectangular, valid light rays that fall on the corners arrive from angles larger than light rays that fall on the middle of the sensor's edge. This is why many hoods have the "petal" form. Otherwise you will suffer from either vignetting at the frame corners, or lower effectiveness in blocking invalid rays.
With increasing focal length, the petal shape becomes less required and there is a transition to circular shape. Another reason for circular hoods is rotating front elements of the lens, where the hood is mounted. When focusing, the element (and hood) rotates so if you use petal hood it will lose its alignment with the sensor.

I know this sentence:
your message has been sent
the subject is no known.
I know this sentence:
you have been registered.
the subject is no known.
but what is this:
I have been really worried these past few days?
here the subject is known, how this is good grammer? why the author not say : "I was worried"? sorry my english is bad
 - worried is a verb, right? Apr 14 '13 at 9:39

 "worried" in your example is an adjective, "to be" is the verb

The first two are examples of present perfect passive. The verbs are respectively "has been sent" and "have been registered". We do not know who did it, that is why we use the passive. Sent and registered are the past participles of the verbs send and register.
The third sentence is an example of present perfect active, where the verb is "have been" (worried is an adjective). You can put it in any tense you want, depending on the context, for example "I was worried about you but now I am fine." or "I have never been more worried in my life."
If you expand the second example further, you will see that worried can not be the verb in this sentence: "I have never been (quite) as worried about you as in these past few hours."
There's a problem over terminology here. Since ELL is about learning language, we should probably stick to the standard meaning of the word "subject" in matters of grammar. Highlighted subjects are...
Your message has been sent.
You have been registered.
The undefined but implicit referent is the agent (who/whatever sent the message, or registered you).
We assume there must be such an entity in those examples, because the meanings of the verbs involved require that there's an agent acting upon an object (technically speaking, acting on a patient).
If the agent is explicitly specified, it may well also be the grammatical "subject"...
John has sent your message.
John has registered you.
...but the agent might not be the subject even when present...
Your message has been sent by John.
You have been registered by John.
Turning to...
I have been really worried these past few days. (again, with the "grammatical subject" highlighted)
...the verb to worry doesn't normally imply an agent acting on an object/patient (there's only really you involved if you say I worry when I go to bed at night).
Semantically, there's not much to differentiate Present Tense I worry from the passive version I am worried. Essentially, the verb to worry is simply being used to create an "adjectival" worried from the past tense, but follow that link if you want the BBC's fine distinction (which I wouldn't bother too much about).
The "headline" difference between Present Perfect passive (not active, I don't think)...
1: I have been really worried these past few days.
...and Simple Past passive...
2: I was worried.
...arises from the fact that Present Perfect (as per the name) implies a stronger connection/continuity from the past to the present time (which may by extension emphasise the duration more). But this is also a "fine distinction". In practice, OP's #1 and #2 are mainly just stylistic choices.
(I can't resist putting this section in, but note that it's not relevant to all learners... :)
The verb to worry can have an agent and a patient, particularly when it has OED's sense 3a...
trans. To seize by the throat with the teeth and tear or lacerate; to kill or injure by biting and shaking. Said e.g. of dogs or wolves attacking sheep, or of hounds when they seize their quarry.
So if we can postulate a sheep who speaks English, she might say...
I was worried yesterday.
...then grammatically, she might mean either of...
That new untrained sheepdog worried me (it attacked me).
I was worried (e.g. - that the new dog might not be able to herd us back into the pen in time for tea).

The Evidence Integration Triangle for Management of Behavioral Psychological Symptoms of Dementia
AuthorAnderson, Courtney E.
MetadataShow full item record
Other TitlesEIT-4-BPSD Manuscript
AbstractProblem and Purpose Behavioral Psychological Symptoms of Dementia (BPSD) are described as symptoms of apathy, agitation, inappropriate vocalization, aggression, wandering, and resistance to care. Incorrectly managing BPSD can lead to the improper administration of psychotropic medications, which can negatively impact the health and quality of life for residents with dementia. The purpose of this quality improvement project was to implement the Evidence Integration Triangle for Management of Behavioral Psychological Symptoms of Dementia (EIT-4-BPSD) in a nursing home. The Evidence Integration Triangle is a four-step implementation framework that includes participatory implementation processes, provision of practical, evidence-based interventions, and pragmatic measures of progress towards goals. Methods The EIT-4-BPSD was implemented over a ten-week period. The four steps included: Step 1: Assessment of the environment and policies; Step 2: Education of staff; Step 3: Establishing person-centered care plans; and Step 4: Mentoring and motivating staff. Outcomes were evaluated pre and post-implementation. Resident outcomes were obtained from the Minimum Data Set National Database and included: use of psychotropic medications and falls. Staff outcomes included knowledge of person-centered behavioral approaches for BPSD based on a 10-item multiple-choice test. Facility outcomes included evaluation of a random sample of five de-identified care plans to evaluate for evidence of incorporation of person-centered approaches to managing BPSD. Results Patient outcomes revealed a 12.5% decrease in the administration of psychotropic medications and a 5.6% decrease in falls. Nurse's post-test knowledge of person-centered management of BPSD increased from 63.5% to 70% post-implementation. Evidence of established personcentered care plans increased from 40% at baseline to 90% post-implementation. Conclusion The EIT-4-BPSD intervention was practical to implement and provided the staff with information and resources to help integrate person-centered behavioral approaches into care plans and routine clinical care. Ongoing work by the nurse champion is needed to continue to maintain the focus on the use of person-centered behavioral approaches.

Fly Ash - The Problem
Based on a study undertaken by the WORLD COAL INSTITUTE,
London, U.K. approximately
3.8 Billion metric tonnes
of coal are mined worldwide each year.
After conversion of the coal into, for example,
400,000,000 metric tonnes
of Fly Ash are left as residue as well as other
waste products. Approximately 10 % of the Fly Ash is used as a by-mix
for other products such as cement, etc. Almost 90 % is tipped onto
spoil heaps or down mines, causing ecological problems.
As a consequence:
- large areas,
quite often attractive countryside or valuable farm land, are
changed into ugly ash tips,
- soil and groundwater
- erosion and
dust cause serious safety and health problems.
- a valuable
raw material is wasted.
However this is a problem that can be solved by
using the IVU-DISPERSOPT Process!

Purpose: A structured didactic radiation oncology clerkship curriculum for medical students is in use at multiple academic medical centers. Objective evidence supporting this educational approach over the traditional clerkship model is lacking. This study evaluated the curriculum efficacy using an objective knowledge assessment. Methods and Materials: Medical students received the Radiation Oncology Education Collaborative Study Group (ROECSG) curriculum consisting of 3 lectures (Overview of Radiation Oncology, Radiation Biology/Physics, and Practical Aspects of Simulation/Radiation Emergencies) and a radiation oncology treatment-planning workshop. A standardized 20-item multiple choice question (MCQ) knowledge assessment was completed preand post-curriculum and approximately 6 months after receiving the curriculum. Results: One hundred forty-six students at 22 academic medical centers completed the ROECSG curriculum from July to November 2016. One hundred nine students completed preand post-clerkship MCQ knowledge assessments (response rate 74.7%). Twenty-four students reported a prior rotation at a ROECSG institution and were excluded from analysis. Mean assessment scores increased from preto post-curriculum (63.9% vs 80.2%, P <.01). Mean MCQ knowledge subdomain assessment scores all improved post-curriculum (t test, P values <.01). Post-scores for students rotating de novo at ROECSG institutions (n = 30) were higher compared with pre-scores for students with ≥1 prior rotations at non-ROECSG institutions (n = 55) (77.3% vs 68.8%, P =.01), with an effect size of 0.8. Students who completed rotations at ROECSG institutions continued to demonstrate a trend toward improved performance on the objective knowledge assessment at approximately 6 months after curriculum exposure (70.5% vs 65.6%, P =.11). Conclusions: Objective evaluation of a structured didactic curriculum for the radiation oncology clerkship at early and late time points demonstrated significant improvement in radiation oncology knowledge. Students who completed clerkships at ROECSG institutions performed objectively better than students who completed clerkships at non-ROECSG institutions. These results support including a structured didactic curriculum as a standard component of the radiation oncology clerkship.

Reader: "Crissy, why does my eyeshadow crease? Whenever I do it, I get these lines in my eyeshadow."
There is nothing more annoying than spending a ridiculous amount of time on your eyeshadow only to find that it begins to crease within a few minutes of you completing it. Has this ever happened to you? Well, if you want to know how to prevent this from happening, keep reading.
What does it mean when your eyeshadow creases? Creasing of the eyeshadows occurs when the oils on the eyelid begin to seep through the shadow causing the eyeshadow to build up in the creases or folds of the eyelids. This buildup is known as creasing. If you're still confused, have you ever looked at your eyeshadow and noticed there are horizontal lines in the shape of your eyes? Well that's creasing sis.
I've seen several tips and tricks along the way to prevent creasing. While no one method is right or wrong, they all have the same goal in common. That goal is creating a solid base for the eyeshadow to stick to. For me, I choose to use a cream base concealer or eyeshadow primer. Not only does this help the eyeshadow stay in place, but it also helps it to appear more pigmented. After I apply the cream concealer or eyeshadow primer, I did not open my eyes anymore. Once you open your eyes, whatever cream or liquid base you choose to use settles into the fold or creases of your eyes. Knowing this, I keep my eyes closed and I dip an eyeshadow brush into a setting powder. Next I apply that setting powder all over the lid. Finally, I allow it to dry prior to opening my eyes.
This process may seem lengthy but it doesn't take any time at all. It should not take more than a minute or two (the entire process). These few short steps Will prevent your eyeshadow from creasing LOL your colors to shine bright.
How do you stop your eyeshadow from creasing? Share your tips in the comment section below!

August 7, 1987 – Lynne Cox becomes the first person to swim from the USA to the Soviet Union
Today in History-
- 1987 – Lynne Cox becomes first person to swim from the United States to the Soviet Union, crossing the Bering Strait from Little Diomede Island in Alaska to Big Diomede in the Soviet Union. Courtesy of Wikipedia.
Lynne Cox (born 1957 in Boston, Massachusetts) is an American long-distance open-water swimmer, writer and speaker. She is best known for being the first person to swim between the United States and the Soviet Union, in the Bering Strait, a feat which has been recognized for easing the Cold War tensions between US President Ronald Reagan and Soviet leader Mikhail Gorbachev.
In 1971, she and her teammates were the first group of teenagers to complete the crossing of the Catalina Island Channel in California. She has twice held the record for the fastest crossing of the English Channel from England to France (1972 in a time of 9 hours 57 minutes and 1973 in a time of 9 hours 36 minutes). In 1975, Cox became the first woman to swim the 10 °C (50 °F), 16 km (10 mi) Cook Straitin New Zealand. In 1976, she was the first person to swim the Straits of Magellan in Chile, and the first to swim around the Cape of Good Hope in South Africa.
Cox is perhaps best known for swimming 2 hour 5 minutes in the Bering Strait on 7 August 1987, from the island of Little Diomede in Alaska to Big Diomede, then part of the Soviet Union, where the water temperature averaged around 43 to 44 °F (6 to 7 °C). At the time people living on the Diomede Islands, only 3.7 km (2.3 mi) apart, were not permitted to travel between them, although the Inuit communities there had been closely linked until the natives of Big Diomede were moved to the Russian mainland after World War II. Her accomplishment a few years before the end of the Cold War earned praise from both US President Ronald Reagan and Soviet leader Mikhail Gorbachev.
At the signing of the INF Missile Treaty at the White House, Gorbachev made a toast. He and President Reagan lifted their glasses and Gorbachev said: "Last summer it took one brave American by the name of Lynne Cox just two hours to swim from one of our countries to the other. We saw on television how sincere and friendly the meeting was between our people and the Americans when she stepped onto the Soviet shore. She proved by her courage how close to each other our peoples live."

Sessions refers to the number of concurrent connections allowed to a SQL database at a time. Workers can be thought of as the processes in the SQL database that are processing queries. The maximum number of sessions and workers allowed depends on your databases's service tier. Blue Matador monitors the sessions_percent and workers_percent metrics so you can know when you've hit the limit.
When the sessions limit is reached, additional connections to the database will be rejected. When the worker limit is reached, clients will receive an error message and will be unable to query your database.
The two possible fixes for reaching the maximum number of sessions: reduce the amount of sessions used by your application, or increase the service tier for your database so there is a higher limit. If your application is using connection pooling, you can configure it so that idle connections are terminated, and limit the number of connections allowed by your application to prevent hitting the limit.
The number of used workers is harder to control since it is not directly tied to the number of sessions. Worker usage can go up during high-usage periods since backed-up queries will consume workers. If you have high worker usage but not session usage, you can use Query Store to analyze your queries to see if specific ones are causing high worker usage.
If you decide to upgrade your database, consult the service tier limits can be found on the following pages to choose an appropriate tier for your session and worker requirements:


Taddeo Zuccaro
Taddeo Zuccaro, Zuccaro also spelled Zuccari (born Sept. 1, 1529, Sant'Angelo in Vado, Urbino—died Sept. 1/2, 1566Rome), Italian painter, leader (with his brother Federico Zuccaro) of the Roman Mannerist school of painting.
Largely self-trained at Rome, Taddeo Zuccaro was influenced by the works of Perino del Vaga and Polidoro da Caravaggio. From the early 1550s he executed many decorative frescoes for facades and interiors of palaces and a few religious works.
From 1559 until his death he was in charge of his greatest commission, the frescoes and stucco decorations of the Villa dei Farnese at Caprarola (Italy)—among the most splendidly ornamented rooms of the time.

Presentation on theme: "Copyright Sautter 2003. EMPIRICAL FORMULAE An empirical formula is the simplest formula for a compound. For example, H 2 O 2 can be reduced to a simpler."— Presentation transcript:
EMPIRICAL FORMULAE An empirical formula is the simplest formula for a compound. For example, H 2 O 2 can be reduced to a simpler formula, HO. Similarly, N 2 O 4 can be reduced to NO 2. Both HO and NO 2 are empirical formulae. Some formulae cannot be reduced and are the empirical formula. An example is H 2 O which cannot be reduced to lower terms. Empirical formulae for compounds can be determined from experimental information such as percent composition data.
The molecular formula is always a whole number multiple of the empirical formula
PERCENT COMPOSITION Percent composition refers to the mass percentage of each element contained in a compound. Percent composition can be determined experimentally or from the formula of a substance. For example, the percentage of carbon and hydrogen contained in methane can be found from its formula CH 4. One mole of CH 4 contains 1 mole of carbon and 4 moles of hydrogen. One mole of carbon has a mass of 12.0 grams and 4 moles of hydrogen have a mass of 4.0 grams (4 x 1.0 grams per mole). The mass of one mole of CH 4 is 16.0 grams (12.0 + 4.0 = 16.0 g) % C = (12.0 / 16.0) x 100 % = 75.0 % carbon % H = (4.0/ 16.0) x 100 % = 25.0 % hydrogen The total of the percents for each element must = 100 % 75.0 % + 25.0 % = 100 %
PERCENT COMPOSITION Problem: A compound is found to contain 0.1417 g of nitrogen and 0.4045 g of oxygen. The sample has a mass of 0.5462 g. What is the percent composition of the compound? Solution: % of X = (grams of X / total mass) x 100 % % N = (0.1417 / 0.5462) x 100 % = 25.6 % % O = (0.4045 / 0.5462) x 100 % = 74.1 % Check : 25.6 % + 74.1 % = 99.7 % ~ 100 % It is often required to find the empirical formula of a compound from data such as that given in this problem. Remember, empirical formula is the lowest whole number ratio of atoms in a compound.
Empirical Formula Calculations Problem: A compound is found to contain 0.1417 g of nitrogen and 0.4045 g of oxygen. The sample has a mass of 0.5462 g. What is the empirical formula of the compound? Solution: All formulae are based on moles. First find the moles of each element present. Moles N = 0.1417 g / 14.0 grams per mole = 0.0101 Moles O = 0.4045 g / 16.0 grams per mole = 0.0253 Now divide the smallest mole value into the other mole values Moles O / moles N = 0.0253moles / 0.0101 = 2.50 Moles N / moles N is of course 1.00 The formula at this point is then NO 2.5 Empirical formula requires the lowest "whole number ratio" Multiplying the formula through by 2 to obtain whole numbers we get N 2 O 5 (dinitrogen pentaoxide)
Empirical Formula Calculations Using Percent Composition Problem: What is the empirical formula for a compound consisting of 37.5 % carbon, 12.5 % hydrogen and oxygen? Solution: We will assume a 100 g sample of the compound. It then consists of 37.5 g C, 12.5 g H and 50.0 g O (100 g sample – 37.5g C – 12.5 g H) Moles C = 37.5 g / 12.0 g per mole = 3.125 Moles H = 12.5 g / 1.00 g per mole = 12.5 Moles O = 50.0 g / 16.0 g per mole = 3.125 Divide each by the smallest mole value Moles C / moles O = 3.125 / 3.125 = 1.00 Moles H / moles O = 12.5 / 3.125 = 4.00 The empirical formula is CH 4 O or CH 3 OH (methyl alcohol)
Empirical Formula Calculations Steps for finding empirical formulae: (1) If percent composition data is given assume a 100 gram sample (2) Convert grams to moles for each element (3) Divide the lowest mole value into each of the other mole values (4) If all the ratios are not whole numbers multiply through to obtain whole number values for each ratio (5) Write the empirical formula using the whole number ratios as subscripts
Empirical Formula Calculations From Combustion (Burning) Data Problem: A compound containing only C, H and O is burned in O 2 to obtain CO 2 and H 2 O. A 0.5438 g sample gives 1.039 g CO 2 and 0.6369 g H 2 O. Find its empirical formula. Solution: All the carbon is contained in the CO 2. Carbon dioxide is 27.3 % C (12.0 / 44.0) so 0.273 x 1.039 g gives 0.283 grams of C The hydrogen is contained in the water which is 11.1 % H (2 / 18) so.111 x 0.6369 g gives 0.0708 g H The rest of the sample is O (0.5438 – 0.283 – 0.0709) or 0.190 grams of O Moles C = 0.283 / 12 = 0.0236 Moles H = 0.0708 / 1.00 = 0.0708 Moles O = 0.190 / 16 = 0.0119 Moles C / moles O = 0.0236 / 0.0119 = 1.98 ~ 2 Moles H / moles O = 0.0708 / 0.0119 = 5.95 ~ 6 Empirical Formula equals C 2 H 6 O or C 2 H 5 OH (ethyl alcohol)
Finding the Molecular Formula from the Empirical Formula and Molar Mass Problem: The empirical formula for polystyrene is CH. It has a molecule mass of 104. What is its molecular formula? Solution: Since the molecular formula is always some whole number multiple of the empirical formula, the molecular mass is always some whole number multiple of the empirical formula mass. The empirical formula mass is 13 (12 for C + 1 for H) Dividing 104 by 13 we get 8. Polystyrene must contain 8 CH units and have a molecular formula of C 8 H 8

When a road surface reaches the end of its useful life it must be replaced. This is generally caused by the number of vehicles that have passed over the road, changes in the drainage of the road or structural failure of the sub-base layers/construction. These conditions are not caused by any chemical changes in the surface material itself.
The surface that needs replacing can be removed in several ways, including the use of pneumatic and hydraulic breakers and road planers. When such a milling operation is undertaken on an asphalt road using a road planer it will produce a variation of material that can be used in a number of different civil engineering applications, this can include: capping, sub base, driveways, hard-standings, car parks and the manufacture of new road surfacing materials.

Worms, viruses, Trojan horses, and spyware: BEWARE!
The National Science Center, or NSC, is now training kids to stay safe from cyber attack malware when they're surfing the web or using email and cell phones. A new online game called Cyber Swarm Defenders is targeted to 6th-8th grade students and is also appropriate for younger students.
The game is part of the NSC's newest Cyber Ops education outreach program. The NSC is a public-private partnership between the U.S. Army and NSC, Inc., that uses its resources to stimulate and increase science, technology, engineering, and mathematics, known as STEM, proficiency in U.S. students, especially those in grades 4-9.
"Anything we can do to make the young students of our country understand the cyber threat and get them excited about STEM technologies has a big payoff," said Ron Ross, chairman of the NSC.
"Educating students about cyber security threats and how to counteract them is imperative," said Mike Krieger, the Army deputy chief information officer, who serves as the secretary of the Army's proponent for the NSC. He also serves as the co-chairperson for the NSC's Partnership Executive Committee, which provides overall direction and oversight for the NSC.
Cyber Swarm Defenders is deployed through the social networking site, which was built for children ages 13 and under. Kid-safe requirements are built in, including a parental control feature. This tower-defense strategy game integrates cyber security education and "learn to earn" mini-exercises. Students earn points, badges and game coins as they strengthen their defenses to advance through the game levels.
"Installing the game on a social network site allows us to reach a variety of students and an existing community of users," said Krieger.
To access the game from the NSC's website and click on the Cyber Swarm banner button. Or, go directly to this site. To play, participants must first register on jabbersmack–which is not accessible on some older versions of browsers.
"Our additional focus on cyber threats also significantly enhances the value proposition of the NSC Partnership," Ross said.
Created by Congress in 1985, the NSC 's outreach programs include online teacher tools, two 18-wheeler Mobile Discovery Center vans, Junior ROTC STEM Outreach activities, and Cyber Ops. In addition to the new game, the Cyber Ops program links to a Malware Comic Book and Malware Mystery game that are also appropriate for older students.

Brigadeiro is a simple Brazilian chocolate fudge candy created in the 1920s. It is named after Brazilian airman Brigadeiro Eduardo Gomes. It's commonly served with soda, coffee or milk.
 1. In a heavy saucepan, mix the milk, cocoa powder and butter. Stir to dissolve the chocolate.
 2. Put over low heat and stir constantly to avoid formation of lumps.
 3. Continue stirring for 10-12 minutes, or until you are able to see the bottom of the pot for one second when you scratch it side-to-side with the spoon. (caution: the more you cook, the harder the resulting candy will be - it may vary from liquid fudge to hard candy)
 4. Allow to cool.
 5. Butter your hands and roll the mixture into small balls (around 2cm in diameter) and roll them over the chocolate sprinkles.
(should you accidentally get hard candy, fill the pot with water and leave to rest - the candy will dissolve completely and the pot will be easy to clean)
You can substitute the cocoa powder for 100g of baking chocolate. If you want a lighter candy use powdered chocolate (such as Nestlé Quick). You can also put raisins or nuts in the center of the candy. You can decorate with powdered sugar instead, or cocoa powder.
Brazilian brigadeiros also have gourmet varieties. Some references are available in specialized houses in Brazil: Maria Brigadeiro and Brigadeiríssimo and Brigadeiro Gourmet

City Systems is a multi-year project conducted by the Institute without Boundaries (IwB) at George Brown College in Toronto, Canada. The project helps students studying 'Interdisciplinary Design Strategy' understand and design more resilient cities during an intensive, hands-on project year. The class of 2011-12 focused on resolving the challenges facing the edge city of Markham, a car-centric suburban community at the edge of Toronto, as it continues to experience rapid population growth. The resulting project, called COLAB, includes a proposal for a new kind of neighborhood: a model sustainable community supported by a 3-way partnership between municipality, local businesses and residents.
The article above was submitted to us by an Inhabitat reader. Want to see your story on Inhabitat? Send us a tip by following this link. Remember to follow our instructions carefully to boost your chances of being chosen for publishing!
A pedestrian plaza and convergence hub are at the heart of the plan. The plaza acts as a focus for community gatherings such as weekend markets, cultural celebrations, public art exhibitions, and the demonstration and testing of new products developed at the convergence hub.
The convergence hub is a change lab that offers shared amenities and office spaces to small and medium-sized businesses specializing in research, demonstration, and commercialization of sustainable technologies and services. The surrounding areas include test spaces for sustainable technologies as they are developed, and an urban farm and nature preserve that teaches local residents about native wildlife and sustainable agriculture practice.
This hub supports and draws new creative people and industries to the region while also enhancing the quality of life of its residents and visitors. Explore the project in detail to learn how a small team of inter-disciplinary students came to understand edge city systems, and how they developed this and other strategies and solutions for a revitalization plan for Markham.

Consider a simple lazy random walk on an $n$-vertex undirected, connected graph: this is the Markov chain which transitions from $i$ to $j$ with probability $p_{ij}=1/(2d(i))$ where $d(i)$ is the degree of node $i$. Note that $p_{ii}=1/2$ for all $i$. Define $C(i)$ be the expected time until a walk starting from node $i$ visits every vertex and let $C = \max_i C(i)$. Let $I(k,l)$ be the expected time until two random walks, starting at vertices $k$ and $l$, intersect (i.e., until they visit the same vertex at the same time). Let $I = \max_{k,l} I(k,l)$.
My question is: can we bound $I$ in terms of $C$? Specifically, is it true that $$ \frac{I}{C} \leq k \log^l n$$ for some constants $k,l$ independent of $n$ and of the graph?
I asked this question on math.stackexchange a week ago without receiving an answer.

Interesting question. Can you elaborate on why you think the inequality should hold? And tell us how you attempted to solve the problem and why it failed? – Pascal Maillard May 23 '12 at 8:18

In Proposition 5 of Chapter 14 of the unpublished book on Markov chains by Aldous and Fill, they show that for continuous time reversible Markov chains, \[ I \le \max\{ \mathbb{E}_i T_j, i,j \in V\}, \] where $\mathbb{E}_i T_j$ is the expected time, starting from state i, until state j is visited. The preceding maximum is clearly bounded from above by $C$, so it follows that $I \le C$. This includes the case of continuous time simple random walk on a connected graph $G$, and a similar argument can be used to to establish the bound for lazy simple random walk on $G$ (in fact, the martingale argument used in the proof is originally described in Chapter 3 of the same book for the case of discrete time walks).

EXCLUSIVE: Mace to discuss mental health innovation at Employee Benefits Live 2017
Judith Grant
EXCLUSIVE: Judith Grant (pictured), associate director, health and wellbeing at construction organisation Mace, will discuss how employers can take an innovative approach to mental health at Employee Benefits Live 2017.
Her session, titled 'Getting proactive with mental health at work', will form part of the health and wellbeing conference stream on Tuesday 10 October, which is also World Mental Health Day.
Presenting alongside Claire Douglas, health and wellbeing manager, Europe at Pitney Bowes, Grant will supply practical tips and ideas on how HR and benefits professionals can be more strategic when implementing a mental health programme.
Grant will highlight how a successful mental health strategy should reach beyond the provision of employee assistance programmes (EAPs), occupational health services, and health insurance to also include workplace conversations. She will explain how this can help organisations take a proactive approach to encourage employees to talk about their mental health concerns earlier and therefore improve outcomes. Grant will also draw on her experience in the construction sector, where suicide is a prevalent issue among staff, and explain why there needs to be more discussion about suicide and mental health at work.
Grant will also look at the importance of internal collaboration when developing an all-encompassing mental health approach in order to ensure that the best results for employees can be achieved.
She said: "Managing mental health at work or supporting mental health at work needs to be far-reaching, so thinking about do [employers] need to train or support people to have better conversations at work? People [who] feel they can talk about their issues earlier on, maybe don't need to go to the employee assistance programme, or rely on the health insurance. Actually having a conversation and talking about how they feel and getting help earlier might prevent a whole lot of pain for that individual and obviously cost for the business as well.
"It is about collaborating with as many different people across the organisation so [employers] can sell the idea of wellbeing in as many different corporate languages as possible so that it lands to whoever it's reaching."
Employee Benefits Live 2017 will take place on Tuesday 10 and Wednesday 11 October at Olympia National, London.

and the reference are different ABIs may no longer link.
There are various ways to form cross-package references in Go, though all depends on //go:linkname (which is explicitly unsafe) or complicated assembly symbol naming. Specifically, the following types of cross-package references may no longer link:
In this table "push" refers to a symbol that is implemented in one package, but its symbol name places it in a different package. In Go this is accomplished with //go:linkname and in assembly this is accomplished by explicitly specifying the package in a symbol name. There are a total of two instances of "asm+push" on all of public GitHub, both of which are already broken under current rules.
"Go+pull" refers to when an unexported symbol defined in one package is referenced from another package via //go:linkname. "asm+xref" refers to any cross-package symbol reference from assembly. The vast majority of "asm+xref" references in public GitHub repositories are to a small set of runtime package functions like entersyscall, exitsyscall, and memmove. These are serious abstraction violations, but they're also easy to keep working.
There are two general groups of link failures in the above table, indicated by superscripts.
In group 1, the compiler will create an ABIInternal reference to a symbol that may only provide an ABI0 implementation. This can be worked-around by ensuring there's a Go function stub for the symbol in the defining package. For "asm" definitions this is usually the case anyway, and "asm+push" definitions do not happen in practice outside the runtime. In all of these cases, type information is available at the reference site, so the compiler could record assembly ABI definitions in the export info and produce the stubs in the referencing package, assuming the defining package is imported.
In group 2, the assembler will create an ABI0 reference to a symbol that may only provide an ABIInternal implementation. In general, calls from assembly to Go are quite rare because they require either stack maps for the assembly code, or for the Go function and everything it calls recursively to be //go:nosplit (which is, in general, not possible to guarantee because of compiler-inserted calls). This can be worked-around by creating a dummy reference from assembly in the defining package. For "asm+xref" references to exported symbols, it would be possible to address this transparently by using export info to construct the ABI wrapper when compiling the referer package, again assuming the defining package is imported.
The situations that cause these link failures are vanishingly rare in public code corpora (outside of the standard library itself), all depend on unsafe code, and all have reasonable workarounds. Hence, we conclude that the potential compatibility issues created by this proposal are worth the upsides.
Calling runtime.panic* from assembly
One compatibility issue we found in public GitHub repositories was references from assembly to runtime.panic* functions. These calls to an unexported function are an obvious violation of modularity, but also a violation of the Go ABI because the callers invariably lack a stack map. If a stack growth or GC were to happen during this call, it would result in a fatal panic.
In these cases, we recommend wrapping the assembly function in a Go function that performs the necessary checks and then calls the assembly function. Typically, this Go function will be inlined into its caller, so this will not introduce additional call overhead.
For example, take a function that computes the pair-wise sums of two slices and requires its arguments to be the same length:
// func AddVecs(x, y []float64)
TEXT ·AddVecs(SB), NOSPLIT, $16
 //... check lengths, put panic message on stack...
 CALL runtime·panic(SB)
This should instead be written as a Go function that uses language facilities to panic, followed by a call to the assembly implementation that implements the operation:
func AddVecs(x, y []float64) {
 if len(x)!= len(y) {
 panic("slices must be the same length")
 addVecsAsm(x, y)
In this example, AddVecs is small enough that it will be inlined, so there's no additional overhead.
Austin Clements will implement this proposal for Go 1.12. This will allow the ABI split to soak for a release while the two calling conventions are in fact identical. Assuming that goes well, we can move on to changing the internal calling convention in Go 1.13.
Since both calling conventions will initially be identical, the implementation will initially use "ABI aliases" rather than full ABI wrappers. ABI aliases will be fully resolved by the Go linker, so in the final binary every symbol will still have one implementation and all calls (regardless of call ABI) will resolve to that implementation.
The rough implementation steps are as follows:
 1. Reserve space in the linker's symbol version numbering to represent symbol ABIs. Currently, all non-static symbols have version 0, so any linker code that depends on this will need to be updated.
 2. Add a -gensymabis flag to cmd/asm that scans assembly sources for text symbol definitions and references and produces a "symbol ABIs" file rather than assembling the code.
 3. Add a -symabis flag to cmd/compile that accepts this symbol ABIs file.
 4. Update cmd/go, cmd/dist, and any other mini-build systems in the standard tree to invoke asm in -gensymabis mode and feed the result to compile.
 5. Add support for recording symbol ABIs and ABI alias symbols to the object file format.
 6. Modify cmd/link to resolve ABI aliases.
 7. Modify cmd/compile to produce ABIInternal symbols for all Go functions, produce ABIInternalABI0 ABI aliases for Go functions referenced from assembly, and produce ABI0ABIInternal ABI aliases for assembly functions referenced from Go.
Once we're ready to modify the internal calling convention, the first step will be to produce actual ABI wrappers. We'll then likely want to start with a simple change, such as putting the stack bound in a fixed register.
Open issues
There are a few open issues in this proposal.
 1. How should tools that render symbols from object files (e.g., nm and objdump) display symbol ABIs? With ABI aliases, there's little need to show this (though it can affect how a symbol is resolved), but with full ABI wrappers it will become more pressing. Ideally this would be done in a way that doesn't significantly clutter the output.
 2. How do we represent symbols with different ABI entry-points in platform object files, particularly in shared objects? In the initial implementation using ABI aliases, we can simply erase the ABI. It may be that we need to use minor name mangling to encode the symbol ABI in its name (though this does not have to affect the Go symbol name).
 3. How should ABI wrappers and go:nosplit interact? In general, the wrapper needs to be go:nosplit if and only if the wrapped function is go:nosplit. However, for assembly functions, the wrapper is generated by the compiler and the compiler doesn't currently know whether the assembly function is go:nosplit. It could conservatively make wrappers for assembly functions go:nosplit, or the toolchain could include that information in the symabis file.

Stanford Biologist Explains the Science of Cap's Strength and Hulk's Muscles
Stanford Biologist Explains the Science of Cap's Strength and Hulk's Muscles
Stanford biologist Sebastian Alvarado wants to make you an agent of S.H.I.E.L.D. — at least a part of their science division.
Working in tandem with Marvel to bring the science of its superheroes to the people in a new Times Square exhibit, Alvarado now has two videos covering his work trying to figure out how to make a regular human into a Captain America or The Incredible Hulk. For Captain Steve Rodgers, the secret is in the serum, as Alvarado explains:
Though there's no way to tell what was in that fictional injection, we have a good idea of what it did for Cap: he had his genes tweaked. For example, we know the genes responsible for the amount of oxygen that is ferried around your blood and that increase muscle mass. These were likely altered for Rodgers. And as the science of genetics advances, being able to turn these genes on and off will plausibly lead to physical enhancements that Captain America enjoys. Epigenetics then — the study of how the environment regulates and changes the expression of genes within our DNA — could get us closer to Cap.
And the "Vita-Rays" that activated all the serum's potential in Rodgers aren't far-fetched either. We are developing drug capsules that can release their contents when hit with ultraviolet light. It's not clear how this delayed reaction would enhance any super serum we come up with, but maybe that is the only way to deliver the drugs safely. Maybe.
Next up is the ion-smashed genome of the Hulk:
The Incredible Hulk is an incredible genetic anomaly. Bruce Banner got his super-powered rage when he was blasted with lethal amounts of gamma radiation. Gamma radiation is dangerous because it has enough energy to be ionizing radiation — electromagnetic radiation (like radio waves or visible light) strong enough knock electrons off of atoms and molecules. So when Banner was exposed to his fateful gamma ray burst, the ionizing radiation ripped atoms and molecules and electrons from his DNA, nearly destroying it. But somehow his body and his DNA rebuilt itself, allowing him to Hulk-out.
Alvarado speculates that what allows the Hulk to transition from Banner to the Big Green Guy also happens to be some kind of epigenetics. Because Banner can transition between the two so easily, it would seem as though certain genetic light switches are being flipped on and then off again. This process is different from something like genetic mutations, which aren't reversible.
My favorite bit of superhero science that Alvarado explains is why the Hulk is green. He muses that because the process of becoming the Hulk is so violent — muscles stretching and tearing, veins popping — the result of the transformation is a lot of cellular damage. Normally, when these damaged cells are recycled by your body, the chemical byproducts can produce a greenish color in the skin, much like how a bad bruise sometimes has a tinge of green. The Hulk is green because he is one big bruise. That would make me angry too.
Alvarado's efforts to bring superheroes closer to science is a part of the interactive Avengers-based exhibition, Marvel's Avengers S.T.A.T.I.O.N., in Times Square in New York City. He and his fellow scientists actually had a panel based entirely on Marvel superhero science at Comic-Con this year, which you can read about here.
Of course, one thing science still can't solve is how Bruce Banner's pants stay on.

Packing problems are a class of optimization problems in mathematics that involve attempting to pack objects together into containers. The goal is to either pack a single container as densely as possible or pack all objects using as few containers as possible. Many of these problems can be related to real life packaging, storage and transportation issues. Each packing problem has a dual covering problem, which asks how many of the same objects are required to completely cover every region of the container, where objects are allowed to overlap.
In a packing problem, you are given:
- 'containers' (usually a single twoor three-dimensional convex region, or an infinite space)
- A set of 'objects' some or all of which must be packed into one or more containers. The set may contain different objects with their sizes specified, or a single object of a fixed dimension that can be used repeatedly.
Usually the packing must be without overlaps between goods and other goods or the container walls. In some variants, the aim is to find the configuration that packs a single container with the maximal density. More commonly, the aim is to pack all the objects into as few containers as possible. In some variants the overlapping (of objects with each other and/or with the boundary of the container) is allowed but should be minimized.
|Covering problems||Packing problems|
|Minimum set cover||Maximum set packing|
|Minimum vertex cover||Maximum matching|
|Minimum edge cover||Maximum independent set|
Packing infinite space
Many of these problems, when the container size is increased in all directions, become equivalent to the problem of packing objects as densely as possible in infinite Euclidean space. This problem is relevant to a number of scientific disciplines, and has received significant attention. The Kepler conjecture postulated an optimal solution for packing spheres hundreds of years before it was proven correct by Thomas Callister Hales. Many other shapes have received attention, including ellipsoids, Platonic and Archimedean solids including tetrahedra, and unequal-sphere dimers.
Hexagonal packing of circles
These problems are mathematically distinct from the ideas in the circle packing theorem. The related circle packing problem deals with packing circles, possibly of different sizes, on a surface, for instance the plane or a sphere.
The counterparts of a circle in other dimensions can never be packed with complete efficiency in dimensions larger than one (in a one dimensional universe, the circle analogue is just two points). That is, there will always be unused space if you are only packing circles. The most efficient way of packing circles, hexagonal packing, produces approximately 91% efficiency.
Sphere packings in higher dimensions
In three dimensions, the face-centered cubic lattice offers the best lattice packing of spheres, and is believed to be the optimal of all packings. The 8-dimensional E8 lattice and 24-dimensional Leech lattice are also believed to be optimal.
Packings of Platonic solids in three dimensions
Cubes can easily be arranged to fill three-dimensional space completely, the most natural packing being the cubic honeycomb. No other Platonic solid can tile space on its own, but some preliminary results are known. Tetrahedra can achieve a packing of at least 85%. One of the best packings of regular dodecahedra is based on the aforementioned face-centered cubic (FCC) lattice.
Tetrahedra and octahedra together can fill all of space in an arrangement known as the tetrahedral-octahedral honeycomb.
|Solid||Maximum known packing density||Lowest upper bound for lattice packing density|
|octahedra||0.947003...[better source needed]||18/19 = 0.947368...|
Packing in 3-dimensional containers
Spheres into a Euclidean ball
The problem of finding the smallest ball such that disjoint open unit balls may be packed inside it has a simple and complete answer in -dimensional Euclidean space if, and in an infinite dimensional Hilbert space with no restrictions. It is worth describing in detail here, to give a flavor of the general problem. In this case, a configuration of pairwise tangent unit balls is available. Place the centers at the vertices of a regular dimensional simplex with edge 2; this is easily realized starting from an orthonormal basis. A small computation shows that the distance of each vertex from the barycenter is. Moreover, any other point of the space necessarily has a larger distance from at least one of the vertices. In terms of inclusions of balls, the open unit balls centered at are included in a ball of radius, which is minimal for this configuration.
To show that this configuration is optimal, let be the centers of disjoint open unit balls contained in a ball of radius centered at a point. Consider the map from the finite set into taking in the corresponding for each. Since for all, this map is 1-Lipschitz and by the Kirszbraun theorem it extends to a 1-Lipschitz map that is globally defined; in particular, there exists a point such that for all one has, so that also. This shows that there are disjoint unit open balls in a ball of radius if and only if. Notice that in an infinite dimensional Hilbert space this implies that there are infinitely many disjoint open unit balls inside a ball of radius if and only if. For instance, the unit balls centered at, where is an orthonormal basis, are disjoint and included in a ball of radius centered at the origin. Moreover, for, the maximum number of disjoint open unit balls inside a ball of radius r is.

Circles in circle
Pack n unit circles into the smallest possible circle. This is closely related to spreading points in a unit circle with the objective of finding the greatest minimal separation, dn, between points.
Optimal solutions have been proven for n≤13, and n=19.
Circles in square
Pack n unit circles into the smallest possible square. This is closely related to spreading points in a unit square with the objective of finding the greatest minimal separation, dn, between points. To convert between these two formulations of the problem, the square side for unit circles will be L=2+2/dn.
Optimal solutions have been proven for n≤30.

Squares in square
Pack n unit squares into the smallest possible square.
Optimal solutions have been proven for n=1-10, 14-16, 23-25, 34-36, 62-64, 79-81, 98-100, and any square integer.

Packing rectangles
Identical rectangles in a rectangle
The problem of packing multiple instances of a single rectangle of size (l,w), allowing for 90° rotation, in a bigger rectangle of size (L,W) has some applications such as loading of boxes on pallets and, specifically, woodpulp stowage.
For example, it is possible to pack 147 rectangles of size (137,95) in a rectangle of size (1600,1230).
Different rectangles in a rectangle
The problem of packing multiple rectangles of varying widths and heights in an enclosing rectangle of minimum area (but with no boundaries on the enclosing rectangle's width or height) has an important application in combining images into a single larger image. A web page that loads a single larger image often renders faster in the browser than the same page loading multiple small images, due to the overhead involved in requesting each image from the web server.
An example of a fast algorithm that packs rectangles of varying widths and heights into an enclosing rectangle of minimum area is here.
Related fields
In tiling or tessellation problems, there are to be no gaps, nor overlaps. Many of the puzzles of this type involve packing rectangles or polyominoes into a larger rectangle or other square-like shape.
There are significant theorems on tiling rectangles (and cuboids) in rectangles (cuboids) with no gaps or overlaps:
- An a × b rectangle can be packed with 1 × n strips iff n divides a or n divides b.
- de Bruijn's theorem: A box can be packed with a harmonic brick a × a b × a b c if the box has dimensions a p × a b q × a b c r for some natural numbers p, q, r (i.e., the box is a multiple of the brick.)
The study of polyomino tilings largely concerns two classes of problems: to tile a rectangle with congruent tiles, and to pack one of each n-omino into a rectangle.
A classic puzzle of the second kind is to arrange all twelve pentominoes into rectangles sized 3×20, 4×15, 5×12 or 6×10.
Packing of irregular objects
Packing of irregular objects is a problem not lending itself well to closed form solutions; however, the applicability to practical environmental science is quite important. For example, irregularly shaped soil particles pack differently as the sizes and shapes vary, leading to important outcomes for plant species to adapt root formations and to allow water movement in the soil.

text: For different applied magnetic fields, the intersubband transitions of double Si delta-doped GaAs structures is theoretically investigated for a uniform donor distribution. The electronic structure has been calculated by solving the Schrodinger and Poisson equations self-consistently. It is found that the intersubband optical absorption and mobility are sensitive to the applied magnetic field: for all allowed intersubband transitions the intersubband absorption spectra show blueshifts. The results open the possibility to design devices for use as optical filters controlled by an applied magnetic field, depending on the delta-doped structure. It is hoped that these results will provide important improvement in device applications, for a suitable choice of magnetic field. (C) 2009 Elsevier Ltd. All rights reserved.

Lab of labs: Blockchain City
Cities as laboratories (see this for a good overview) have been the talk of the town for a while now — but what do we really mean by it and more importantly, what are the underlying structures that allow such fluid and experimental forms emerge?
Last week I took part in a 'Lab of Labs': a series of hands-on design charrettes that explored a variety of approaches for living labs and design research practices and methodologies. The different labs explored the role empathy can play in designing inclusive interactions in the city, how roots and identities are expressed in the context of global cities, methods for designing for sociality in smart cities as well as the emerging role blockchain can play in reimagining the economic systems that underpin everything that surrounds us (the latter was run by the The Centre of Design Informatics at the University of Edinburgh and attended by yours truly).
And this is where it gets interesting. In the past decade I took part in countless workshops, design conferences, charrettes and competitions about various aspects concerning 'cities' — almost always conceptualised as an abstract measurement unit, rather that a living, continuously forming collision of human and non human systems. This was the first time where a deliberate question around the values we exchange (or want to exchange) was shaped through unpacking the economic systems that underpin all our monetary and non-monetary transactions.
The methodology was straightforward, yet insightful: exploring blockchain through physical mimicking (with Lego!), playing with tech probes (imagine us running around Amsterdam staring at our phones in order to collect mili-Bitcoin rewards and then trying to guess what the rules of the transactions were), moving onto ideation and prototyping.
This allowed us to have a conceptual understanding of the topic, from which a series of questions emerged:
- What are the values underpinning the current economic system and what types of value are exchange (subtle, yet significant distinction)?
- Who are the actors? What's the power dynamic?
- What values do we want to form the basis of an emerging economic system and how can we be deliberate about the change we want to see?
- What are the inherent qualities about blockchain and how can they be explored to the maximum to engender a transition towards a sustainable future?
- How can blockchain be used beyond an incentive / reward / fining model (for some background on DAOs — decentralised autonomous organisations see _USER_ blog here)?
- What's the untapped potential of geolocating transactions that otherwise happen online? Could this bring a different meaning to 'special economic zones'?
Not that we found the answers, but below you can see the resulting rough skeletons that start showing glimpses of what some of the applications and pitfalls of a blockchain city could look like:
In the context of signs of anarcho-capitalism forming in front of our eyes (see this recent piece from The Guardian: 'Tech titans are busy privatising our data'), how can this third wave of self-organising / commons / citizen innovation (as we call it at Forum) help us question the status quo and act deliberately to unlock the paradigm shift we need?

Peanut oil, also known as groundnut oil, is a mild tasting vegetable oil derived from peanuts. The oil is available in refined, unrefined, cold pressed, and roasted varieties, the latter with a strong peanut flavor and aroma, analogous to toasted sesame oil.
It is often used in Chinese, South Asian and Southeast Asian cuisine, both for general cooking, and in the case of roasted oil, for added flavor. Peanut oil has a high smoke point relative to many other cooking oils, so is commonly used for frying foods. Its major component fatty acids are oleic acid (46.8% as olein), linoleic acid (33.4% as linolein), and palmitic acid (10.0% as palmitin). The oil also contains some stearic acid, arachidic acid, arachidonic acid, behenic acid, lignoceric acid and other fatty acids.
Antioxidants such as Vitamin E are sometimes added, to improve the shelf life of the oil.
The oil had increased use in the United States during World War II, due to war shortages of other oils.
According to the USDA data upon which the following table is based, 100 g of peanut oil contains 17.7 g of saturated fat, 48.3 g of monounsaturated fat, and 33.4 g of polyunsaturated fat.
Most highly refined peanut oils

Atone Ritual 4
Uncommon Abjuration
Cast 1 day; Cost rare incense and offerings worth a total value of 20 gp × the target's level; Secondary Casters 1, must be the ritual's target
Primary Check Nature or Religion (expert); Secondary Checks Nature or Religion (whichever is used for the primary check)
Range 10 feet; Targets another creature of up to 8th level who is a worshiper of the same deity or philosophy as you
You attempt to help a truly penitent creature atone for its misdeeds, typically actions contrary to your deity's alignment or anathema to your deity. If the creature isn't truly penitent, the outcome is always a critical failure. This ritual uses Nature if the target is a druid, and Religion in all other cases.
 - Critical Success The creature receives absolution for its misdeeds, allowing it to regain standing with your deity. It returns to its previous alignment (if its alignment shifted) and regains any abilities it lost. Before the atonement is complete, the creature must perform a special quest or other task chosen by your deity, as befits its misdeeds. If completed during downtime, this task should take no less than 1 month. For 1 month, the target receives divine insight just before performing an act that would be anathema to your deity or contrary to your deity's alignment.
 - Success As critical success, but the creature gains no special insight regarding its subsequent actions.
 - Failure The creature does not receive absolution and must continue to meditate and redress its misdeeds. Any future atone rituals for the same misdeeds cost half as much and gain a +4 circumstance bonus to primary and secondary checks.
 - Critical Failure The creature offends your deity and is permanently cast out from the faith. The creature can't rejoin your religion without a more direct intervention.
Heightened (5th) Increase the maximum target level by 2 and the base cost by 20 gp.

Reflections: Why was the hatter mad?
Why was the hatter mad?
By William L. Bulla
What is a Mad Hatter? He is not something we experience in our every day life. However, he is something we read about, even as children, in the story of "Alice in Wonderland", and again, "Through the Looking Glass."
Over the years we have read about both the Mad Hatter and his partner the March Hare. Both of these characters have seemed a bit mad.
Recently my friend Sean asked, "why do they say'mad as a hatter'?" I said I thought it came from Lewis Carroll's "Alice In Wonderland". He told me I was wrong. He said it had to do with the mercury used in preserving the furs from which they made the hats. Of course, I didn't believe him so I decided I should look into the issue. Sean was right. It was the chemicals used in preserving the fur used in making hats that caused the hatter's to go "mad".
The most famous Mad Hatter, of course, is the one from the Mad Tea Party in Alice in Wonderland, the partner of the March Hare. Both mad, of course. But Lewis Carroll did not invent the phrase, although he did create the character. The phrases "mad as a hatter" and "mad as a March hare" were common at the time Lewis Carroll wrote the first publication of Alice In Wonderland in 1865. The phrase had been in common use in 1837, almost 30 years earlier. Carroll frequently used common expressions, songs, nursery rhymes, etc., as the basis for characters in his stories.
The origin of the phrase, it's believed, is that hatters really did go mad. The chemicals used in hat-making included mercury nitrate, used in curing felt. Prolonged exposure to the mercury vapors caused mercury poisoning. Victims developed severe and uncontrollable muscular tremors and twitching limbs, which became known as "hatter's shakes"; other symptoms included distorted vision and confused speech. Advanced cases developed hallucinations and other psychotic symptoms.
The victims were the hatters, not the wearers of hats. The hatters were exposed to the mercury fumes, which would have been long dissipated, or of insignificant strength, by the time the hat was worn. This use of mercury is now subject to severe legal restrictions (if not banned) in the U.S. and Europe.
The March Hare and the Hatter make a brief reappearance in Alice Through the Looking Glass as the King's messengers, "Haigha" and "Hatta." These names are the only hint as to their identities other than the illustrations from the book published in 1871.
"In that direction," the Cat said, waving its right paw round, "lives a Hatter: and in that direction," waving the other paw, "lives a March Hare. Visit either you like: they're both mad."
"But I don't want to go among mad people," Alice remarked.
"Oh, you can't help that," said the Cat: "we're all mad here. I'm mad. You're mad."
"How do you know I'm mad?" said Alice.
"You must be, said the Cat, "or you wouldn't have come here."
So, who knows for sure? Maybe we all become a bit mad in March.

In the wiki it is article only about shear modulus and it is written that it's unit is Pascal. At the same time in all researches about Red Blood Cells shear stresses, authors write "in-plane shear stress" and measure it in N/m. For instance, here - _URL_ I can't understand why - perhaps it is a difference between in-plane shear modulus and shear modulus. Or it is because membrane is a surface in 3D, not the whole body. Any ideas?

When we talk about shear stress and shear modulus we're normally considering the deformation of a 3D body. However the article you cite is not talking about deformation of a 3D body but instead it's treating the surface of the erythrocyte as a 2D object. That means they use a surface stress which is probably better known as surface tension. This is similar to the way you calculate the deformation of soap films.
Surface tension (and therefore surface stress) is a force per unit length so it's units are N/m, and therefore the surface shear stress has the same units of N/m.

Materials Used to Make Cable Ties and their Applications
While cable ties are usually used to bundle together wires and cabling, they can be used for many other purposes as well, such as identifying hazardous materials. Since they are manufactured in several colours, businesses can use them to help code substances or to secure loads during transport. Most cable ties are nylon, but they can be made of other materials as well, allowing them to hold up to different stresses and exposure to different substances.
Materials for Cable Ties
Cable ties replace the use of string, twine, or rope to secure bundles of wires, cabling, or other types of materials. They hold up better against various stresses and are available in a variety of materials. If you install IT cabling or wiring, your company can order custom-printed ties to help identify the purpose of the cables or wires being secured together.
Nylon Cable Ties
Many cable ties are manufactured from nylon because this material holds together well under all types of stress. Nylon cable ties are not easily broken, so they can be used for multiple purposes. While most cable ties are black, white, or grey for generic use, coloured cable ties can be used to colour code the wires or cables being bundled together, allowing quick identification.
All cable ties have a flame-resistance requirement, so nylon cable ties come in either 6.6 nylon or 4.6 nylon, which is a higher-temperature nylon. While most cable ties are used for indoor purposes, they can also be used outdoors. Black cable ties are UV-protected for use outdoors as well as indoors, because they are also resistant to different types of environmental contaminants. Black nylon ties are made from a 12-grade nylon because they require a higher tensile strength.
Stainless Steel Ties
Rust-resistant cable ties in Melbourne are used for strapping together materials which may be exposed to saltwater or chemicals. So, if you have a marine company or a business that handles corrosive chemicals, these ties would be the best for strapping things down on a boat or identifying containers of chemicals. This helps ensure the safety of employees as well.
Metal-detectable Cable Ties
Companies in the food, beverage, or pharmaceutical industry will need to use metal-detectable cable ties so they can be detected by x-ray machines or metal detectors. These ties have metal bits embedded into the material so they can be detected. They can be used to secure cables or hoses during processing to help prevent contamination.
Depending on the materials being bundled and what they may be exposed to, this type of cable tie comes in two varieties: halar fluoropolymer and tefzel fluoropolymer. Halar fluoropolymer ties are used to bundled qualified cable. They are flame-resistant and meet UL flammability standards.
Tefzel fluoropolymer cable ties are used for applications in which they will be exposed to environmental stresses like chemical exposure, ultraviolet and gamma radiation, or extreme temperatures. It is important that these ties survive these stresses, in order to help identify the materials they hold together.
Depending on the materials your company works with, these cable ties can help identify what is bundled together.

Parallel solution of systems of linear equations generated by COMSOL 3.2 using the Sun Performance Library
Publication: Research › Report – Annual report year: 2006
This note investigates the use of the Sun Performance Library for parallel solution of a system of linear equations generated by COMSOL 3.2. In many engineering disciplines this is a computational bottleneck for large problems which are often met in research practice. Most researches are primarily concerned with developing a proper (COMSOL) model rather than developing efficient linear algebra solvers which motivates this investigation of the efficiency of the coupling COMSOL + SPL. The technicalities of making such a coupling is described in detail along with a measure of the speedup for a testproblem run in 2D and 3D. Moreover this note quantifies the performance of COMSOL running on a Sparc ULTRA III processor. The study shows that for small problems such as debugging tasks, teaching exercises etc. the Sun computer is not competitive compared with a standard PC.
