Environmentalists call EPA to remedy coverup in Brunswick
BRUNSWICK, GA. | Environmentalists are calling an EPA remedy for a contaminated outfall canal that empties into a tidal creek a literal cover-up.
The EPA's interim record of decision says it will allow Hercules Inc. to fill a canal contaminated with the banned pesticide toxaphene and to build a new concrete-lined outfall ditch to reroute water from its former chemical plant on Brunswick's eastern border. Some who have seen the plan say the EPA is allowing Hercules to bury its pollution rather than removing it.
"They're going to do the cover up instead of the cleanup. They just don't think a chemical plant needs to clean up their waste every 100 years," said Daniel Parshley, executive director of the Glynn Environmental Coalition.
The outfall canal runs from the former Hercules plant, where the company once made gunpowder, cotton poison and food additives, to Terry Creek. The canal and parts of Terry Creek were dredged in the late 1990s to remove toxaphene but subsequent tests showed the insecticide was still in the sediment.
Parshley said that a method used in March 2010 didn't probe deeply enough to determine where the contamination ended and the clean earth began.
After environmentalists complained that the EPA had not gone deep enough in collecting samples, the EPA's Office of Inspector General promised that concern would be addressed, he said.
"They regressed back to the old method to hide the poison," he said.
The water leaves the plant site — now owned by another company — through a lined ditch, crosses under U.S. 17 and enters the wide canal that empties near the confluence of Terry Creek and Dupree Creek.
The interim remedy to address the sediment contamination requires Hercules to do the following:
- Reroute the discharge into a newly constructed concrete-lined channel;
- Place a geo-textile fabric over existing sediment in the outfall ditch;
- Back-fill the outfall canal with compacted clean soil;
- Armor the remaining slope of the ditch;
- Seed and stabilize any disturbed areas;
- Conduct periodic inspections, maintenance and sediment removal;
- Develop a long term monitoring plan.
Although those are the components of the interim remedy, the design for implementing the plan must still be done, the EPA said in a release.
The EPA has been working at the site for about 20 years. Hercules made toxaphene there by reacting chlorine gas with extracts from pine stumps. The result was a sticky, yellow pesticide used in the 1970s and early 1980s to control bowl weevils on cotton and other crop pests, for insect infestation of livestock and even to kill unwanted fish.
It was banned in 1990 and the EPA considers it a probable carcinogen, the federal Agency for Toxic Substances and Disease Registry has said. It has also caused liver and kidney damage when consumed in large doses, the agency said.
The state Environmental Protection Division approved the interim remedy, but it also dealing with chemicals that left the Hercules grounds and contaminated groundwater beneath the industrial grounds and property across U.S. 17 that is hundreds of yards away. Water samples taken from wells has detected a number of chemicals, most notably benzene, far above federal limits.
The Glynn Environmental Coalition, other environmental watchdog groups and the owners of some neighboring properties have said they want the EPA to order sampling to see how deep the contamination reaches and to excavate it rather than just leaving it in place to further contaminate groundwater and the estuary.
The EPA will place a final copy of the interim record of decision and supporting documents in the designated site repository in the Marshes of Glynn main library at 208 Gloucester St., Brunswick.

In the Light of Truth – The Grail Message (MP3 CD)
גרמניה: 1-3 ימי עסקים, במדינות אחרות: 5-30 ימי עבודה
In the Light of Truth: The Grail Message is a classic work that offers clear and perceptive answers to questions which challenge every human being. Written between the years 1923 - 1937, it is a collection of 168 essays addressing all spheres of life ranging from God and the Universe to the Laws in Creation, the meaning of life, responsibility, free will, intuition and the intellect, the ethereal world and the beyond, justice and love. It answers eternal questions such as what does it mean to be human, what is the purpose of life on Earth, and what happens to "me" when I die. In the Light of Truth: The Grail Message explains the causes and significance of the unprecedented crises facing humanity, and our responsibilities to the future.
Concerning In the Light of Truth: The Grail Message, Abd-ru-shin writes:
"I wish to fill in the gaps which have so far always remained unanswered in the souls of men as burning questions, and which never leave any serious thinker in peace, if he honestly seeks the Truth."
Throughout the Grail Message readers are urged to weigh questions and answers intuitively, to confront them within their own life experiences, and only to believe that which they can perceive inwardly. Only through this process can one reach true conviction in one's life.

text: This paper analyzes the agreed and discrepant sensemaking of members of a project team. Embedded in a narratological approach to sensemaking research, we argue that before scholars may be able to understand in detail how agreements are reached and action becomes coordinated, we need first to take seriously the proposition that sensemaking occurs in the context of individuals' idiosyncratic efforts at identity construction. This, we suggest, means attending to the narratives that actors tell about their work and self both for others and their selves. The key research contribution that we make is to demonstrate how work on 'impression management' and 'attributional egotism' may be employed in order to account for discrepant sensemaking. This is important in the context of a literature that has left relatively unexplored the reasons why people interpret differently experiences they have in common.

PERU: Largest Recovery Of Antiquities Returns To Peru
The pieces include prehispanic pots and textiles, Colonial Cusco-school paintings, prehistoric bones, and Colonial hand-hammered macuquina coins (cobs).
The recovery is the result of several years of work, based on agreements signed by Peru with different countries on the protection and return of historical artifacts. The agreements served to build 22 different legal cases to reclaim pieces that had been found or stolen and smuggled out of the country for the lucrative antiquities market. One of the most famous processes was the Janeir Aude case in Argentina, which took 14 years to recover 4,136 artifacts, including a mummy bundle.
In total, 4,174 pieces were recovered from Argentina, 88 from the United States, 79 from Chile, two from Canada and one from Spain. It was the largest collection of recovered pieces handed over at the same time to the Ministry of Culture.
According to the Ministry of Culture, it has worked closely with the Ministry of Foreign Relations over the past five years in the recovery of antiquities throughout the world. More than 8,000 artifacts have been returned also from Germany, Australia, Bolivia, Brazil, Denmark, Egypt, France, Italy, Japan, Mexico, Russia, Switzerland and the United Kingdom.

The Nested DFX design methodology moves the HD.RECONFIGURABLE property down and up through the hierarchy. Implementation tools follow standard DFX design rules based on what cells are currently defined as reconfigurable. This holds true for write_bitstream as well; partial bitstreams will only be created for cells currently holding the HD.RECONFIGURABLE property.
With any fully routed design checkpoint open in Vivado, use write_bitstream to generate full and partial bitstreams. Remember, by default this command will generate a standard full bitstream for the entire device and a partial bitstream for each cell defined as reconfigurable. Two options can limit results to one or the other:
- The -cell option will generate ONLY a partial bitstream for the requested cell.
- The -no_partial_bitfile option will generate ONLY a standard full device bitstream.
If the full design image you need a full device bitstream for, use a combination of open_checkpoint and read_checkpoint -cell (and update_design -black_box if necessary) to assemble a complete routed design, filling in each module one at a time with routed RM checkpoints. Use report_route_status to confirm that the design is complete.
For example, to create all bitstreams possible for the above design configuration, follow these steps. These commands assume that checkpoints for each module alone (each routed, and some locked) have been created using the same naming conventions as the A1 variants.
open_checkpoint top_A2_Y1_Z1_routed.dcp update_design -black_box -cell A/Y read_checkpoint -cell A/Y Y2_routed.dcp write_bitstream top_A2_Y2_Z1.bit
This last command will create three bitstreams:
- top_A2_Y2_Z1.bit, which is the full design bitstream for the entire device
- top_A2_Y2_Z1_pblock_Y_partial.bit, which is the partial bitstream for Y2 only
- top_A2_Y2_Z1_pblock_Z_partial.bit, which is the partial bitstream for Z1 only
Note that the names for the partial bitstreams are automatically generated. The name always starts with the base name you provided, followed by the RP pblock name, followed by partial. If you would like to have names that show the name of the current RM (for example Y2), then call write_bitstream on the target RP directly:
write_bitstream -cell A/Y top_A2_Y2_partial.bit write_bitstream -cell A/Z top_A2_Z1_partial.bit
Partial bitstreams can only be generated for cells currently marked as HD.RECONFIGURABLE. In order to create a partial bitstream for RP A, pr_recombine must be called before write_bitstream.
pr_recombine -cell A write_bitstream -cell A A2_Y2_Z1_partial.bit
A full device bitstream for this image would be identical to one generated prior to pr_recombine, as the full device bitstream does not have any special programming indicating that later that device will be partially reconfigured.

What is the influence of pulp concentration on classification effect? Why can't the concentration be too low?
The viscosity of the pulp is also reduced when the pulp concentration is low. Therefore, the sedimentation speed of the ore particles is also accelerated, and the particle size of the overflow product obtained is also finer. Conversely, the overflow product particle size is coarser.
However, it should be pointed out that when the pulp concentration is reduced to a certain level, if the concentration continues to decrease, the particle size of the overflow product will become coarser. The main reason is that when the concentration decreases a lot, the volume of the pulp (or the amount of pulp) is also very large, so that the pulp flow rate (upward flow rate and horizontal flow rate) in the classifier also increases. Consequently, the coarser ore particles are also flushed into the overflow product. In order to comply with regulations, pulp concentration must be reasonably controlled.
It is said that the amount of ore entering the classifier should be appropriate and the ore feeding should be uniform. Why is this so?
During periods of constant slurry concentration, increasing ore feeding into the classifier results in an increase in flow rate, which causes the overflow product to become coarser. When the amount of ore decreases, the particle size of the overflow product becomes finer, and the content of fine particles in the returned sand also increases.
Therefore, the ore feeding amount of the classifier should be appropriate. In particular, the ore feeding should be uniform, and the fluctuation range should be as small as possible, so that the classifier can work under normal processing conditions and obtain a good classification effect.


Knowledge of exercise recommendations and energy intake from foods and beverages in relation to exercise behaviors within two Hispanic border communities
Danene (DJ) Moberly, The University of Texas School of Public Health
Abstract
This research is a secondary analysis of the Qué Sabrosa Vida population-based cross-sectional study of two predominately Mexican American communities located along the Texas-Mexico border in 2000. There were two aims for this research. The first was to determine the relationship between knowledge of exercise and water recommendations, and exercise behavior and water consumption. The second was to determine the relationship between exercise behavior and percentage of energy consumption from beverages. Chi-square analysis revealed the majority of both populations had adequate knowledge about water and exercise recommendations, although significant percentages of the populations (>40%) did not consume water or exercise in adequate amounts. Knowledge was found to be a component of both behaviors, as it was more prevalent in the adults who exercised and consumed water in adequate amounts. Analysis of variance revealed no significant difference between overall beverage calorie percentage and exercise level (all p-values > 0.05); both regions and genders reported ∼18% of total caloric intake from beverages. There was no disproportionate influence of beverage calories on total caloric intake, after controlling for water consumption and independent of exercise behavior. These findings suggest that overall caloric intake, from both foods and beverages, may be the most influential factor to the energy imbalance contributing to the obesity crisis in these Hispanic border populations.

Fly masks paired with an insect repellant, can greatly reduce the amount of stress faced by your horse during fly season. An alternative to traditional insect repellants, we also carry feed throughs which when ingested can help ward off pesky insects without the use of sprays.
Dr. Timothy Gibb, Clinical Professor of Entomology at Purdue Agricultural University in Indiana, explained: "Fly masks are used to relieve the stress that a horse deals with when continually fighting flies – primarily the face fly. Face flies are persistent and annoying while they feed around the eyes and nose of horses. They are capable of transmitting eye-worm to horses but this is not common. The mask simply acts as a physical barrier between the horse and the flies."

There are so many ways to be brave.
Sometimes being brave means saying yes, even though you're scared. Sometimes being brave means saying no, even though you're scared. But being brave will always mean being at least a little bit scared, and doing the scary thing anyway.
Here's to all the brave balloons floating through the sky, terrified, and flying anyway.
1. Support the child to blow up the balloon, taking big, deep, belly breaths. (If they are unable to do so, do it for them, while they breathe along with you!)
2. Take turns kicking/heading/hitting the balloon into the air, aiming to keep it from hitting the floor
3. Any time the balloon hits the floor, share a time you were brave.

Sliding sports are not easy to access. We need to be fully equipped which is expensive and cumbersome. Moreover, learning to practice them is a hard task. This is why, as a designer, I aim to make them accessible. It should not distort the environment : it is the soul of those sports.
When sliders are practising, it increases the potential energy in their body. That is why they are exposed to personal injuries or even death if they do not control it. However, if we want to improve our skills, we need to practise. In that kind of sports, we learn from our mistakes.
This learning method scares a lot of people. That is why I will suggest reducing personal injuries via a new kind of accessible protections that do not hinder movement.

Spirit Science 11_11 ~ DNA Activation
DNA Activation is a reconnection of your original blueprints for life to a higher frequency, or perhaps a "fuller" frequency. As you live your life, and grow, and have the experiences that you have, you may find yourself opening up to a greater awareness and greater knowing of what things mean all around you.
This awareness is made in the connections between the hearts of everyone. This looks like saying what you mean and meaning what you say. Breathing, staying calm, asking questions, looking at everything thoroughly, doing what you love and loving what you do.
Love is not just an affection of another or a feeling you get, but the awareness of the infinite connection with everything. You are one with everything, so am I for that matter, and being in a space of Love is sharing in the knowing that You and I are One consciousness.

Comprehensive National Power
From Wikipedia, the free encyclopedia
Jump to navigation Jump to search
Comprehensive National Power (CNP) (Chinese: 综合国力; pinyin: zōnghé guólì) is a putative measure, important in the contemporary political thought of the People's Republic of China, of the general power of a nation-state. CNP can be calculated numerically by combining various quantitative indices to create a single number held to measure the power of a nation-state.[citation needed] These indices take into account both military factors (known as hard power) and economic and cultural factors (known as soft power).
A fairly simplistic and effective index was developed by Chin-Lung Chang. It uses critical mass, economic capacity and military capacity. Due to its indicators, it is often repeatable and easy to define, making it comparable to the Human Development Index in understanding and reliability.[1]
The book "Comprehensive National Power- A Model for India", a project of United Service Institution of India explains how CNP is calculated and also shows various methods of calculation with various tables, charts, diagrams.[2]
National Strategic Resources[edit]
Michael Porter lists five major resources, that is, physical, human, infrastructure, knowledge and capital resources. Accordingly, the national strategic resources are divided into eight categories, with 23 indictors.[3] Those categories constitute CNP:[4]
 - Economic resources
 - Natural resources
 - Capital resources
 - Knowledge and Technology resources
 - Government resources
 - Military resources
 - International resources
 - Cultural resources

Legends describe the Fini as a gigantic, gaping maw, usually filled with grasping tendrils that lash out at any living being to approach.
The Fini is said to spawn hordes of grotesque demons to wreak havoc and spread misery. Some tales go further still, claiming that these demons were once people whom the Fini seduced, consumed and then vomited back onto the land, soulless, to attack their own kin.
In the tales, the Fini would often be defeated by heroes wielding powerful necromancy, but there are also many instances where the story was left unfinished, suggesting that writers of the time were too idle and unprofessional to complete their work.
Since the Fini has not appeared in literature for over a thousand years, it is assumed to be nothing more than religious claptrap, invented in the savage years after the Mist when our ancestors were confused and primitive.

Why You May Need to Use a Telehandler for Your Business
Whether you work in an industrial setting, agriculture or a warehouse, you may need a telehandler at some point. These machines provide a lot of benefits that cannot be overlooked. In general, they are responsible for lifting and hoisting heavy items. Learn more about why you may be interested in a telehandler rental in Chicago.
What Is a Telehandler?
Telehandlers are also often referred to as telescopic handlers. At first glance, they appear to be the same as a forklift. However, there are actually many differences between the two. A telehandler rental in Chicago actually has a boom attached to it. This means that it can perform many of the same operations as a crane. This is the main difference between a telehandler and a forklift.
More About Booms
Booms give the telehandler the ability to hoist items. These attachments are usually able to move in a forward direction. They can also extend upwards for several feet. In addition, the person operating the telehandler can add other attachments to the end of the boom. This makes it a truly versatile tool for use in a wide variety of environments.
Consider the Attachments
As mentioned, there are many ways to add attachments to a telehandler. You may find it necessary to use a lifting jib for carrying jobs. You might also need an earthmoving bucket for heavy items. Finally, you can always rely on fork tines to get the same benefits as a forklift.

Best fertility doctors in Hyderabad can deal with Sperm DNA fragmentation. It is advisable to visit the best infertility hospital in Hyderabad. It is worth the try.
It would be interesting to focus on sperm DNA Fragmentation about fertility levels. Best infertility doctors in Hyderabad can deal expertly with sperm DNA fragmentation tests.
Sperm DNA fragmentations happen to be a term made use of a term that is used to describe irregular sperm genetic material, which can result in male sub-fertility, IVF failure, and miscarriage.
What is DNA fragmentation in sperm?
Fragmentation of Sperm DNA can rather occur spontaneously or by laboratory personnel un-intentionally. Spontaneous DNA fragmentation does accumulate gradually in a cell. Fragmentation of DNA is, in fact, more common among men who suffer from defective sperm quality. Best Test Tube baby hospital in Hyderabad has adequate facilities for DNA Fragmentation.
It is made use of for predicting results of IVF and ICSI. DNA fragmentation index helps determine the success rate of IVF.
Various studies have shown that –
- High sperm DNA fragmentation does affect the creation of blastocyst
- The higher levels of DNA fragmentation, lower chances of failed model treatment as well as miscarriage
- Sperm DNA fragmentation is rather higher in sub-fertile men with irregular sperm parameters
- The high sperm DNA fragmentation is rather found among men with normal sperm count.
Best infertility doctors in Hyderabad are well versed in DNA fragmentation.
Types of DNA Fragmentation Test :
Sperm DNA damage happens to be common among young as well as elderly men. There are various tests available to assess the fragmentation of the sperm in the DNA. Two of the most common tests are – Sperm Comet Test and SCSA.
SpermComet Test :
A SpermComet Test is rather conducted by a specialist to check the quality of a man's sperm and DNA.
SCSA (Sperm Chromatin Structure Assay) :
SCSA refers to the issue of assaying the structure of sperm chromatin as a new diagnostic tool that can identify sperm samples with a high degree of DNA fragmentation.
Depending on reproductive history, the SCSA can be recommended for some patients. This examination is of course not a measure of the ability of the sperm to fertilize an egg.
Advantages of Sperm Fragmentation Test :
- Provides a comprehensive study of sperm DNA integrity that helps in aiding the identification of men at risk of sub-fertility
- Provides information that does help in male fertility clinical diagnosis, treatment, as well as management.
- It does provide prognostic quality in determining the outcome of fertility treatment like IVF or IUI.
Factors that cause damage to the DNA of the sperm :
Several factors do damage sperm DNA –
- Age – Age is an important factor. Damage to DNA can be enhanced with the age of the men.
- Men having a chronic infection in the prostate
- Exposure to toxic agents as well as chemicals
- Excessive heat
Causes of Sperm DNA Fragmentations :
Apart from stress ,there are other contributing factors to sperm DNA fragmentation –
- Infection and Pyrexia
- Abortive Apoptosis
- Advanced Age
- Occupational and Environmental Pollutants
- Recreational drugs
- Lapse of time from ejaculation
- Intrinsic causes such as recombination deficiencies during spermatogenesis
- Increase in testicular temperature
- Variations in the expression of sperm protein
Therefore, it is advisable to understand the significance of the sperm DNA fragmentation test before proceeding with any sort of infertility treatment.

Fuel Flow Transmitter
A Fuel Flow Transmitter measures the rate of flow and converts this to an electrical signal to drive a meter or other equipment. In this Transmitter a turbine is used as the driving element in place of the conventional electric rotor. Turbine speed is controlled by a spring-operated valve, which allows some fuel to by-pass the turbine at high flow rates. This feature has improved transmitter reliability, significantly reduced transmitter size and weight, eliminated the need for an electrical power supply and, allied with improvements to the pulse pick-off, has allowed the transmitter harness to be reduced to three wires in an enveloping screen.
The original Tornado Turbine Driven True Mass Flowmeter Trans¬mitter was fitted to DAI and DA2 with RB199 engines.
A Dry Fuel Flowmeter was initially fitted to the EJ200 engine. This was de¬velopment of the Tornado flowmeter to meet the EJ200 engine require¬ments and it first flew on the DA3 aircraft.
A new Total Fuel Flowmeter was however, required to measure very high dry/ reheat mass fuel flowrates with extremely low pressure drop and high resistance to fuel contamination debris. This was the unit fitted to production aircraft.
This unit is a Dry Fuel Flowmeter initially fitted to the EJ200 engine.

What you're trying to do is fairly simple, and if you step back from the upper/lower-case issue it's just "replace 't' with 'T'". You can do this using:
string1.replace('t', 'T')
share|improve this answer

Let me try this again. :^) The loop won't execute because t.islower is the method, and 'x in some_string' requires x to be a string, and so a TypeError is raised. – DSM Mar 11 '12 at 22:58

Yep, I was being hasty and not thinking it through. Edited my answer to just ignore that, as your analysis is correct :) – James Aylett Mar 11 '12 at 23:00

You would need to set string1 each time equal to the string returned by 'replace'. Otherwise, if string1 originally contained a 't', it would loop infinitely. – TheDude Mar 13 '12 at 3:03
I think you should have:
string1 = 'timbucktwo'
while 't' in string1:
 string1 = string1.replace('t', "T")
 print(string1)

text: Description: Baañke is a hairy vine with branched tendrils. It is known in English as the "field pumpkin." Leaves of Baañke are triangular or heart-shaped, up to 30 cm (12 in) long, with pointed, toothed lobes. The flowers are large and yellow, and the fruit is orange when ripe and regularly furrowed. Although baañke refers to the pumpkin producing plant, other varieties of this species (Cucurbita pepo) produce different vegetables such as summer squash, scallop squash, and yellow-flowered gourds (small, hard-shelled, variously shaped, ornamental fruits).

Hello everyone,
I have been trying (without success) to determine the following. Let $P$ denote the space of monic polynomials of degree $n$ with complex coefficients, which have distinct roots. It is known that the fundamental group of this space is the braid group $B_n$. Let $X \rightarrow P$ denote the universal cover. Then $B_n\subset Aut (X)$ where $Aut (X)$ is the group of holomorphic automorphisms of $X$. For $n\geq 4$, is it true that $Aut (X)=B_n$? I do not see any other automorphisms (but I am a novice in the area).
share|improve this question
The space $X$ is very close to the Teichmuller space $T=T_{0,n+1}$, but they are a bit different: You can still act on $P$ (and, hence, on $X$) by complex affine transformations. Once you mod out $P$ (and $X$) by such action, you get the space $T$. It is Royden's theorem that for $n\ge 4$ the full group of biholomorphic automorphisms of $T_{0,n+1}$ is the mapping class group of the corresponding $n+1$-punctured sphere. The same holds for other finite type Riemann surfaces with few low-complexity exceptions (exclude torus, once punctured torus and 4 times punctured sphere). – Misha Feb 4 '13 at 18:17
Thanks, Misha. This really answers my question. I forgot about the action of affine transformations. – Venkataramana Feb 5 '13 at 0:30

Corundum brick's compressive strength at room temperature, flexural strength at room temperature, and high-temperature flexural strength at 1400°C. For the compressive strength at room temperature, the T100 of corundum bricks made of tabular corundum as the aggregate is as high as 147MPa, which is twice the T0 of the fused white corundum bricks made of fused white corundum. Similarly, the flexural strength of plate corundum bricks at room temperature and high temperature is also significantly higher. The strength of bricks made entirely of fused white corundum is not only related to the corundum aggregate itself but also related to the ceramic bond formed after the brick is fired. The Main Components of Different Corundum Bricks are the following.
The Physical and Chemical Properties and Advantages of Corundum Bricks
The alumina content of corundum brick is more than 90%, and it is a refractory product with corundum as the main crystal phase. High compressive strength at room temperature, up to 340MPa. High load softening start temperature, greater than 1700°C. Very good chemical stability, strong resistance to acidic or alkaline slag, metal, and glass liquid. Thermal shock stability is related to its organizational structure. Dense products have good corrosion resistance but poor thermal shock stability.
Let's summarize the advantages of corundum bricks:
- It has good sintering activity and can improve the density of corundum bricks.
- Corundum bricks of tabular corundum have high bulk density and low apparent porosity.
- It has high normal temperature compressive strength, normal temperature flexural strength, and high-temperature flexural strength.
- The best wear resistance.
- The corrosion resistance and permeability of coal gasifier slag and oil residue are better than pure fused white corundum bricks.
- As an aggregate, it can improve the thermal shock stability of corundum bricks.
The Main Components of Different Corundum Bricks
Because there are many refractory materials on the market, different corundum bricks are widely used. Because of its good use effect, it is used in a variety of high-temperature industrial furnaces. In fact, corundum brick is a refractory material with alumina content greater than 90%, and often containing trace impurity elements Cr, Ti, Fe, and V. Corundum bricks on the market can also be divided into the following concentrated types according to the composition.
- Brown corundum bricks are mainly made of bauxite and coke (anthracite). The main chemical composition is aluminum oxide, titanium oxide ring contains a small amount of silicon oxide and iron oxide. The microhardness is HV1800-2200, and the toughness is higher than SIC. Abrasive tools made of brown corundum are suitable for grinding metals with high tensile strength, such as various general steels, malleable cast iron, hard bronze, etc.; they can also be used to make brown corundum bricks, which are a kind of advanced refractory materials.
- High-alumina corundum bricks are made of high-quality bauxite as the main raw material, and sub-white corundum bricks are produced on the basis of high-quality brown corundum bricks. Its chemical composition and physical properties are similar to those of white corundum. Sub white corundum is produced on the basis of high-quality brown corundum. Because its chemical composition and physical properties are similar to white corundum, it is called sub-white corundum. Bulk density≥3.8g/cm2, refractoriness≥1850℃. The product has the hardness of white corundum bricks and the toughness of brown corundum bricks. It is an ideal high-grade refractory material and abrasive material.
- White corundum bricks are made by high-temperature smelting with alumina powder as raw material. It is white, slightly higher in hardness than brown corundum brick, and slightly lower in toughness. Made into abrasive tools suitable for the grinding of high carbon steel, high-speed steel, and quenched steel. White corundum can also be used for grinding and polishing materials, as well as precision casting sand, spraying materials, chemical catalysts, special ceramics, and advanced refractory materials.
- Zirconium corundum bricks are made by smelting alumina and zirconia as raw materials in an electric arc furnace at a high temperature above 2000°C. Tough texture, dense structure, and high strength. The main mineral phase of zirconium corundum is a eutectic formed by a-alumina and alumina-zirconia. In order to ensure the quality of zirconium corundum, in addition to a reasonable selection of parameters and technology, cooling technology and processing technology. Choosing appropriate additives to reduce the silicon oxide content in the zirconium corundum bricks, making the alumina and zirconia eutectic, and having a uniform structure is also the key to the production of zirconium corundum bricks.
Classification of Corundum Bricks
Different Corundum Bricks are divided into semi-recombined or directly combined corundum bricks and dense corundum bricks. Semi-recombined or directly combined corundum bricks are made from fused corundum (or sintered corundum) and sintered alumina fine powder. Aluminum sulfate or paper pulp waste liquid is the binding agent. After high-pressure forming, it is a corundum refractory product sintered at a high temperature of 1750~1800°C. Dense corundum bricks are made of light-burned alumina fine powder. Carboxymethyl cellulose or dextrin is the binding agent. It is a corundum refractory product made by artificial granulation, press molding, and sintering at a high temperature of 1750~1800°C. It has the characteristics of high Al2O3 content, extremely low apparent porosity, high strength, corrosion resistance, and strong erosion resistance. It is suitable for the lining of synthetic ammonia converter.
Different Corundum Bricks are also classified into light corundum bricks and heavy corundum bricks according to their bulk density. Corundum bricks with different bulk densities have different performances and require different physical and chemical indicators.
So, what is the chemical composition of fused cast zirconia corundum bricks?
Fused zirconium corundum brick is also called fused zirconium corundum, commonly known as white iron brick. An electrofusion cast refractory material mainly composed of oblique zircon and corundum. A mixture of zircon (or industrial zirconia) and alumina as the main raw materials are made by melting, casting, and annealing in an electric arc furnace. Its chemical composition is: Zr0230%~50%, Al20340%~50%, Si0210%~17%. The mineral composition is mainly corundum oblique zircon eutectic, with a small amount of oblique zircon, corundum, and glass phase. The bulk density is 3.25～3.70g/cm3, the apparent porosity is 0.5%～7%, the compressive strength is 200～500MPa, and the load softening point is 1720～1760℃. Mainly used in glass kilns.
Application Industries of Different Corundum Bricks
Finally, I would like to summarize which industries corundum bricks are suitable for. Corundum bricks have excellent corrosion resistance, wear resistance, high-temperature strength, load softening temperature, creep, and other thermodynamic properties. It is widely used as a lining material for cracking, reforming furnaces, metallurgical industries, slag gasifiers, coal gasifiers, carbon black reactors, pulp waste liquid gasifiers, and other industrial furnaces in petrochemical and fertilizer industries.

By optimising the optical unit, EXNER's transmitted light sensors can now be used as standard up to a process pressure of 16 bar.
Why should high-quality sensors that are already successfully used in various applications be made even better? This question was raised when optimising the optical unit of all sensors for absorption measurement. The answer: Continuous product optimisation with users in mind and increasing safety and reliability when using the product.
By optimising the optical unit of the sensors for absorption measurement, even higher processing quality could be achieved. This now makes it possible, among other things, to use the sensors as standard up to a process pressure of 16 bar.
All sensors for absorption measurement in the EXcell, EXplore 131 and EXspect 231 series benefit from the optimisations described. Last year, by improving the optical unit in the backscatter sensors in the EXplore 131 and EXspect 271 series, a permissible process pressure of 20 bar could be achieved.

Question: Is there a certain safe level for blood sugar for a person that has diabetes?
I know a high blood sugar level affects being able to drive safely. Is there a certain level where a ticket will be written if known by the State Patrol?
Answer: There is no level where a ticket would be written by the Minnesota State Patrol.
Of course, I am not a doctor, but I do know that the blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood.
Blood glucose monitoring is the main tool you have to check your diabetes control. This check tells you your blood glucose level at any one time.
Even though there is no blood sugar level where a ticket would be written, if an incident or a crash occurs involving a diabetic loss of consciousness or voluntary control and a trooper or any law enforcement officer investigates, a request for an examination of the driver can be submitted to the Driver and Vehicle Services – Driver Evaluation Unit.
This can be a very serious matter, and the best advice is to ask your healthcare provider what your blood sugar levels should be. Some other reasons for a driver's re-examination can include:
- General physical/health problems.
- Vision problems.
- Lack of physical driving skills.
- Mental or emotional problems (road rage, memory loss, etc.).
- Loss of consciousness (seizures).
- Lack of knowledge of traffic laws.
- And others.
Thanks for asking, and let's all work together to create a traffic safety culture in Minnesota.
Remember also to slow down, buckle up, drive sober and pay attention!
If you have any questions for future columns concerning motor vehicle traffic in Minnesota, send them to: Sgt. Curt S. Mowers MN State Patrol P.O. Box 644 Brainerd MN 56401. Email questions to _EMAIL_ with "Ask a Trooper" in the subject line. Questions are edited.


Apple confirmed that the new Apple Watch series 6 will include blood oxygen monitoring* and we show you how you can set it up.
Here's what you need
 - Make sure that the Blood Oxygen app is available in your country or region. You will be able to see this during the setup process.
 - Update your iPhone 6s or later to the latest version of iOS.
 - Update your Apple Watch Series 6 to the latest version of watchOS.*
 - The Blood Oxygen app is not available for use by people under 18 years old.
*The Blood Oxygen app is not available if you set up your Apple Watch with Family Setup.
Set up the Blood Oxygen app and background readings
 1. On your iPhone, open the Health app.
 2. Follow the onscreen steps. If you don't see a prompt to set up, tap the Browse tab, then tap Respiratory > Blood Oxygen > Set up Blood Oxygen.
 3. After you complete set up, open the Blood Oxygen app on your Apple Watch to measure your blood oxygen levels.
If you still don't see the Blood Oxygen app on your Apple Watch, you can search the App Store on your Apple Watch for Blood Oxygen and download it.
The Blood Oxygen app is installed during the setup in the Health app. If you deleted the Blood Oxygen app, you can install it again from the App Store on your Apple Watch if you've completed the Blood Oxygen app setup.
Take a blood oxygen measurement
You can take a blood oxygen measurement at any time with the Blood Oxygen app.
 1. Make sure that your Apple Watch is snug but comfortable on your wrist.
 2. Open the Blood Oxygen app on your Apple Watch.
 3. Stay still, and make sure your wrist is flat with the Apple Watch facing up.
 4. Tap Start, then keep your arm steady for 15 seconds.
 5. Wait. The measurement takes 15 seconds. At the end of the measurement, you will receive the results.
 6. Tap Done.
About background measurements
The Blood Oxygen app on your Apple Watch will occasionally measure your blood oxygen levels if background measurements are on. This will usually happen when you are not moving. Depending on how active you are, the number of readings collected each day and the time between these readings will vary. Blood oxygen measurements use a bright red light that shines against your wrist, so it may be more visible in dark environments. If you find the light distracting, you can turn off background measurements.
 1. Open the Settings app on your Apple Watch.
 2. Tap Blood Oxygen, then turn off In Sleep Mode and In Theater Mode.
Blood oxygen measurements only occur during sleep if the Track Sleep with Apple Watch setting is turned on.
How to get the best results
 1. Rest your arms on a table or in your lap while you take a measurement with the Apple Watch facing up. Keep your wrist flat, and hold as still as you can.
 2. Make sure that your Apple Watch isn't loose on your wrist. The band should be snug but comfortable, and the back of your Apple Watch needs to be touching your wrist.
 3. Make sure that the back of your Apple Watch is flush with the top of your wrist. If your wrist bones interfere with this, move your watch up your arm away from your wrist bone.
Additional factors
Even under ideal conditions, your Apple Watch may not be able to get a reliable blood oxygen measurement every time. For a small percentage of users, various factors may make it impossible to get any blood oxygen measurement.
 - Skin perfusion (or how much blood flows through your skin) can impact measurements. Skin perfusion varies significantly from person to person and can also be impacted by the environment. If you are out in the cold, for example, the skin perfusion in your wrist might be too low for the sensor to work with the Blood Oxygen app to get a measurement.
 - Permanent or temporary changes to your skin, such as some tattoos, can also impact performance. The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult for the Blood Oxygen app to get a measurement.
 - Motion is another factor that can affect your ability to get successful background or on-demand measurements. Certain postures, such as arms hanging by your side or fingers in a fist position will also result in unsuccessful measurements.
 - If your heart rate is too high (above 150 bpm) while at rest, you won't be able to get a successful blood oxygen measurement.

Background: There has been no study conducted about the effect of autosuggestion on quality of life for geriatric patients. Our aim was to evaluate the efficacy of autosuggestion for geriatric patients' quality of life and its impact on psycho-neuro-endocrine-immune pathway. Methods: Sixty geriatric patients aged ≥60 years in a ward were randomly assigned to either receive autosuggestion or not. Autosuggestion was recorded in a tape to be heard daily for 30 days. Both groups received the standard medical therapy. Primary outcome was quality of life by COOP chart. Secondary outcomes were serum cortisol level, interleukin-2, interleukin-6, interferon-γ, and N-acetylaspartate/creatine ratio in limbic/paralimbic system by magnetic resonance spectroscopy. The study was single blinded due to the nature of the intervention studied. Results: Out of 60 subjects, 51 finished the study. The autosuggestion group reported better scores than the control one for quality of life, COOP chart 1.95 vs. 2.22 (95% CI, p = 0.02). There were increments of serum cortisol (p = 0.03) and interleukin-6 in the autosuggestion group (p = 0.04). Interleukin-2, interferon-γ, and N-acetylaspartate/creatine ratio in prefrontal cortex showed a tendency to increase in the autosuggestion groups. Conclusion: Autosuggestion is associated with improvement of geriatrics' quality of life, serum cortisol level, and adaptive immunity. There is a better trend for neuroplasticity in prefrontal cortex in the autosuggestion group.
- quality of life
- serum cortisol

3. Damage to the reinforcement layer
(1) The hose is cracked. The braided wire near the crack is rusty. If the hose breaks, peel off the outer rubber layer to find the broken surrounding the braiding, winding wire rust, mainly due to the external rubber layer wet or corrosive substances, so that the strength of the hose reduced, resulting in a rupture at high pressure. When this happens, it is usually accompanied by external fracture, wear or severe deterioration, which causes the outer adhesive layer to lose its protective effect on the reinforcing layer. At this point, external factors such as mechanical damage, chemical corrosion and high temperature baking of the outer adhesive layer need to be checked and eliminated before the hoses are replaced. However, there are also cases where the outer rubber layer remains good but the reinforcing layer is rusty and ruptured. Damaged mouth is usually within 200mm of the hose connector, most of the reason is because the connector is not qualified, because the moisture into the inner edge of the outer sheath, so the reinforcement layer absorbs moisture and causes rust, resulting in soft strength and rupture.
(2) The hose reinforcement layer is not rusty. However, there is an irregular wire break phenomenon, if the hose breaks, peel off the outer glue layer, found that the reinforcement layer is not rusty. However, the length direction of the enhanced layer appears irregularly broken. The main reason is that the hose is affected by high-frequency impact. There are many intersections between the braided reinforced wire and the wire. When the pressure in the tube changes greatly, these intersections also change with the diameter of the tube, causing the wires to rub against each other. If the hose is subjected to high-frequency impact pressure, the intersection will experience frequent friction, resulting in a broken wire. For hoses that are often subjected to high-frequency shocks, a wire-wounded skeleton should be used as an enhanced layer.

Wandle Valley Living Landscape - London Wildlife Trust
The River Wandle is a unique south London chalk stream.
The Wandle has been identified as one of London's five flagship rivers by the Environment Agency.
Once, this river teemed with wildlife including trout and otter, but by 1960 it was officially declared a sewer. Subsequently much-improved through active conservation effort, the Wandle now supports fish and other wildlife, but still flows through significant stretches of industry, residential areas and commercial centres.
This scheme aims to restore six kilometres of urban river habitat in the River Wandle catchment to create a thriving landscape that supports a rich variety of species and habitats, provides connectivity for people and wildlife, is adaptable to climate change and encourages access and enjoyment by people.
The Wandle Valley is a flagship urban river restoration project, demonstrating how partners can work together to restore a functional river corridor for people and wildlife.
Its value as a regional priority has been recognised by Natural England and the area has been proposed as a new regional park.
We have focused our recent efforts on habitat restoration in-stream and on our Wilderness Island nature reserve.
We are also developing a strategy for the future reintroduction of water vole.
Start date: 2008
Scheme area: 500 hectares
Trust reserves within the scheme
This scheme is helping species including...
Current threats to the landscape:
Habitat loss and fragmentation, pollution, climate change, inappropriate development, non-native species (e.g. mink, Chinese mitten crab).
This scheme is also...

Members can add personal information about their living family members, however:
- You must not share information regarding a living person without that person's explicit permission.
- You must not share information about a living child under 16 without parental consent.
- You must not share any information about a living child under 13 unless you are their parent and legal guardian. Even profiles of children created by parents should be considered placeholders only and not contain any sensitive information.
- You must not share any information about DNA tests for other living people.
So, I guess it comes down to what it means to "share" information about a living person. Is posting a profile of a living person "sharing" information about that person? To post the profile of a living person, nowadays, you often have to enter an estimated birth date. Is that considered sharing? I'm looking for some clarity here.
Does it mean that I can't add someone to the trusted list of a living person without the permission of the person of whom the profile is written? Does it mean I can't send the info to someone else in e-mail?

Editors' Note: This is an updated version of our 2019 Thanksgiving article.
Today, millions of Americans will sit down to enjoy Thanksgiving dinner with friends and family. A recognizable menu at any time of year, the traditional meal features cranberry sauce, mashed potatoes, rolls, pumpkin pie, stuffing and, of course, turkey! Before enjoying your sumptuous meal, take a few moments to read how this holiday is made possible by compressed air and gas technologies:
Automate Those Lines! Before the food you eat makes it to the table, it must be packaged and transported – but how does it even get to the packaging area? With the help of air compressors! Compressed air is used to control the valves and actuators in automated lines for filling, packaging, and bottling; low-pressure compressed air will also help move the food down the production line so that packaging can occur.
Bottling. What's Thanksgiving dinner without a glass of wine? Bottling is the quintessential application for compressors and nitrogen generators in winemaking. Air compressors provide the pressurized air that moves the wine from the barrels to the bottles, and because wines are particularly susceptible to oxidation during bottling, using an inert gas like nitrogen to remove the oxygen from the empty bottles helps ensure the freshness of the wine. N2 is also used to eliminate the carbon gases from the bottles prior to capping.
Canning. Vacuum pumps and nitrogen generators are also used in canning, which is a necessary process for other Thanksgiving favorites like pumpkin puree and cranberry sauce. Vacuum is used to form the can, stamped from a single piece of aluminum, and to hold the cans as they move down the line. Because aluminum is nonmagnetic, the vacuum level must be able to hold the cans as they are lifted, set down and filled. Nitrogen generators also play an important role in canning, as they introduce nitrogen into the cans holding the end products. Every pocket of space in the cans are filled with nitrogen, thus removing the oxygen eliminating moisture and mold. What you are left with is a fresher, tastier product that stays that way for longer.
Cooling and Spraying. Baked goods like dinner rolls and sweet breads are iconic parts of the Thanksgiving day meals. Compressed air is used to cool down baked goods after they emerge from the oven, which helps prevent contamination and product spoilage.
Food Packaging. Vacuum and nitrogen technology are essential elements of the Thanksgiving Day feast. Because turkeys are distributed across the country, they must be packaged and frozen prior to being shipped to their final destination. This is accomplished with both vacuum pumps and nitrogen generators:
The vacuum process removes atmospheric oxygen from the food packages to prevent aerobic bacteria and fungi from growing.
Meanwhile, on-site nitrogen generation ensures that the food doesn't spoil by displacing the remaining oxygen from the package in a process called MAP, or Modified Atmospheric Packaging, which inhibits aerobic spoilage. This is especially important for perishable meats that can quickly sour without proper precautions! Keep in mind that turkeys aren't the only food item that benefit from compressed air and gas technologies, however. MAP with nitrogen is commonly utilized in snacks, coffee, cheese, pasta, baked goods, sandwiches and processed meats. It is also becoming increasingly popular in fresh-cut produce, like pre-packaged salads and fruit, for convenience, quality, and more variety.
We hope everyone has a safe and happy Thanksgiving! Enjoy your time with family and friends, and if you'd like to learn more about compressed air and gas, you can find us at _URL_

The importance for children's wellbeing, long-term adjustment and maintenance of loving and supportive relationships with both parents after divorce is well documented. However, questions remain about links between parenting arrangements and relationship outcomes, specifically in terms of the ways that shared overnight care after separation may interact with complex developmental or family circumstances to influence children's outcomes. This article summarises two recent Australian studies of post-separation shared parenting arrangements, with a focus on developmental outcomes for children in two risk groups: children living with ongoing parental conflict after separation, and infants and pre-schoolers. Both studies help to illuminate the socio-economic, relationship and developmental "equipment" required for translating a shared time arrangement post separation into a developmentally supportive experience for the children concerned.

Education is in demand by everyone, everywhere. So there are opportunities to open educational businesses even in rural areas, as Vusala Ahmadova, an entrepreneur from Azerbaijani city of Tovuz, knows firsthand.
Some years ago Ahmadova, an English teacher from north-west Azerbaijan, decided to open her own business, and started to cast around for opportunities. After a while, she settled on the area she knew best – education – and opened in Tovuz the branch of Edu Prime Education Academy.
This private educational institution offers various classes for children's mental and physical development, early development, and preparation for primary school. It offers a range of other subjects, including language classes, for which Ahmadova makes use of the experience she gained from years of studying and working as a teacher.
But first of all, to become an entrepreneur she herself had to take some training and work on her own skills. Only after that did entrepreneur have enough knowledge about the education business to be able to achieve success.
Providing financial stability
After taking some training, Ahmadova still felt she needed to boost here confidence in order to develop her new business. She was not sure if she would be able to hire more employees, provide them financial stability, and make her business grow. That's where the EU-funded project "Improved Support for Entrepreneurial Development in Rural Areas," part of the EU4Business initiative, came to her aid.
As part of the project, Ahmadova along with other woman entrepreneurs took part in training on self-assessment and improving self-esteem, gaining useful information for business planning and other important issues.
"I started almost everything from scratch, so I had a lot of difficulties, both financially and in terms of skills," Ahmadova says.

Supporting women's entrepreneurship

If you're a fan of Dungeons & Dragons, chances are you know how essential dice are in this iconic tabletop role-playing game. DND dice are curiously shaped polyhedral gems that can make or break your game. While there are different types and sets available, choosing the right dice can be daunting. But don't worry, this guide is here to help you navigate the world of DND dice. We'll explain their types, sets, and essential uses so you can focus on having fun and telling stories with your friends.
Understanding the Basics – DND Dice Types
Before we dive into dice sets and their uses, let's start with the basics: the types of dice used in Dungeons & Dragons. There are seven main types, represented by a 'd' followed by the number of sides:
- D4: A four-sided pyramid-shaped die for small damage rolls and certain character abilities.
- D6: The classic six-sided die, commonly used for everything from damage rolls to skill checks.
- D8: This eight-sided die is often utilized for weapon damage and healing spells.
- D10: There are two types of ten-sided dice in DND: the percentile die (marked from 00 to 90) and the regular d10 (marked from 1 to 10). These are used for various rolls, including damage and determining percentages.
- D12: A twelve-sided die primarily used for larger weapon damage rolls and some class features.
- D20: The iconic twenty-sided die, the most famous in DND. It's employed for attack rolls, saving throws, and determining the outcome of many actions.
- D100: A percentile die used together with the percentile d10 to determine random percentages.
Building Your Dice Set
Now that you know the dice types, let's talk about assembling your dice set. A typical DND player's set includes the following:
- 1d20: The workhorse of your set, used for many important rolls.
- 1d12 and 1d10: Useful for certain character classes and damage rolls.
- 1d8: Another significant die for damage and healing.
- 2d10: One for regular rolls and one for percentages.
- 1d6: Used for various rolls, including damage and skill checks.
- 1d4: Essential for smaller damage rolls and abilities.
Having these dice readily available ensures you're prepared for any in-game situation. Some players prefer to have multiple sets in different colors or designs for style and convenience.
Exploring Special Dice and Their Uses
Beyond the basic dice, there are special dice that come into play in specific situations:
- Fudge Dice: A set of four six-sided dice with two plus faces, two minus faces, and two blank faces. Used in the Fudge system for determining degrees of success or failure.
- DND Condition Markers: Not actual dice, but condition markers often come in dice form to track various conditions like poison or concentration.
- Legendary Dice: Unique dice sets that are sometimes released with special DND campaigns or events. These dice can have special effects or designs that make them highly collectible.
Collecting and Caring for Dice
Many Dungeon & Dragons enthusiasts see collecting dice as a hobby in itself. Dice come in various materials such as metal, acrylic, or gemstone, each offering a distinctive feel and aesthetic. Keeping your dice in a soft pouch or container is recommended to prevent wear and tear. However, if you're more of a practical player, there are many affordable options that work just as well.
Understanding the types of DND dice and knowing when and how to use them is crucial to the game. As storytellers, dice are our secret weapons, and having the right set at hand can enhance our gaming experience and bring us closer together as a community. So, whether you're a seasoned Dungeon Master or a new adventurer, use this guide to choose your perfect set of dice, and embark on epic quests that will keep you entertained and engaged for hours on end.

Hoonderts HSD yard in Flushing has initially been established for the dismantling and recycling of ships, shipwrecks and offshore installations. These structures contain a diversity of hazardous materials and this requires extensive measures to prevent any negative environmental impact. One of these measures is a 35.000 m2 fluid tight floor with a separate sewerage system. Contamination of the soil is prevented in this way. The separate sewerage system allows full control over the rainwater and other substances that can be present on the surface. The collected water is monitored regularly and is discharged to a waste water treatment plant. In case of a spill the relevant sections of the sewerage system can be closed immediately.
The HSD yard has a quay of 200 meters long that is sheltered from direct waves of the North Sea. The water depth at the quay side is LAT -7,5 meters increasing to LAT -11,5 meters LAT at 20 meters outside the quay. The yard is located in the Western Scheldt estuary, about 10 nm form the North Sea and has unrestricted access (no bridges etc.) to the open sea. The area is served by main highways and a railhead at about 3 km from the yard.
The total area of 35.000 m2 provides more than enough space for storage as well. The yard can facilitate storage of large structures for longer periods of time without interferences with projects in progress. This Intermediate storage capacity ensures that operations offshore can continue undisturbed.
The features makes the yard a multipurpose land sea interface that will not only serve dismantling projects but many other offshore related activities as well.
The most important HSD yard features are:
- Fenced off area (35,000 m) fully paved with a high load fluid tight floor (intrusion of contaminants in the soil and groundwater is inhibited);
- Directly located at a sea harbor with an adjacent quay 200 long. Unrestricted access to and from the North Sea;
- Quay load capacity: 5 tons/m2 increasing to 10 tons/m2 at 10 m from quay's edge. The quay is suitable for RoRo operations of heavy structures like topsides and jackets;
- Water depth at quayside at LAT: 7.5 meters water;
- Average tidal variance is approx. 4,5 meters (approx. 5,5 meters at spring tide conditions);
- Anchoring facilities (additional mooring points can be provided);
- Quay side suitable for the receipt and mooring of offshore barges;
- Equipment for loading, offloading, handling and cleaning;
- Calibrated weighbridge;
- Closed sewerage system. Full control over spillage and rainwater (zero discharge);
- Provisions preventing dust emissions (sprinkler devices);
- Storage facilities for hazardous materials and waste;
- Valid -environmental- licenses for all offshore related projects including dismantling, recycling, disposal, cleaning and storage of hazardous materials and waste.
- Experienced and dedicated staff that is committed to a successful completion of every project.

Typewritten page of canary onionskin, 1912. Note the translucency in the upper right corner, where the red library stamp on the transverse is visible.
Onionskin or onion skin is a thin, light-weight, strong, often translucent paper. Not made from onions, it is named for their thin, papery skins which it superficially resembles. It was usually used with carbon paper for typing duplicates in a typewriter, for permanent records where low bulk was important, or for airmail correspondence.[1] It typically has a 9-pound basis weight, and may be white or canary-colored.
In the typewriter era, onion skin often had a deeply textured cockle finish which allowed for easier erasure of typing mistakes, but other glazed and unglazed finishes were also available then and may be more common today.
Onionskin paper is relatively durable and lightweight due to its high content of cotton fibers. Because of these attributes and its crispness when folding, onionskin paper is one of the best papers to use for toy kites and advanced paper airplanes. Paper airplanes made from onionskin paper tend to fly very well due to their low weight and high integrity once folded.

Why Neptune And Uranus Appear In different Colours?
Why Neptune And Uranus Appear In different Colours?
Astronomers now have an explanation for why Neptune and Uranus appear in different colours.
 - Neptune and Uranus have much in common — they have similar masses, sizes, and atmospheric compositions — yet their appearances are in different shades of blue.
 - At visible wavelengths, Neptune is a rich, deep azure hue, while Uranus is a distinctly pale shade of cyan.
 - The reason is that the haze around Uranus is thicker than that around Neptune.
 - Uranus's stagnant, sluggish atmosphere makes it appear a lighter tone than Neptune.
 - If there was no haze in the atmospheres of Neptune and Uranus, both would appear almost equally blue as a result of blue light being scattered in their atmospheres.

a pod of eleven killer whales - a family of two adults and nine juveniles - was discovered trapped in the ice of the hudson bay off the coast of the small inuit village of inukjuak. confined for two days in the small breathing hole, the whales began to panic as they tried unsuccessfully to find another breathing hole and their way to sea.
while an icebreaker ship would typically be brought in to free the orcas, the closest crew was thirty six hours away, so the villagers decided to cut a half mile of holes for the killer whales to travel through on their way to open water. the village mayor noted that it was unusual to see orcas in the area in january, but that the waters were late to freeze this year.

A cog railway, rack-and-pinion railway or rack railway is a railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail. This allows the trains to operate on steep gradients.
The first cog railway was the Middleton Railway between Middleton and Leeds in West Yorkshire, England, UK, where the first commercial steam locomotive, The Salamanca, ran in 1812. This used a rack and pinion system designed and patented in 1811 by John Blenkinsop.
The first mountain cog railway was the Mount Washington Cog Railway in the US state of New Hampshire, which carried its first fare-paying passengers in 1868 and reached the summit of Mount Washington in 1869. The first rack railway in Europe was the Vitznau-Rigi-Bahn on Mount Rigi in Switzerland, which opened in 1871. Both lines are still running.
A number of different rack systems have been developed. Today, the majority of rack railways use the Abt system.
The Riggenbach rack system was invented by Niklaus Riggenbach working at about the same time as, but independently from Marsh. Riggenbach was granted a French patent in 1863 based on a working model which he used to interest potential Swiss backers. During this time, the Swiss Consul to the United States visited Marsh's Mount Washington Cog Railway and reported back with enthusiasm to the Swiss government. Eager to boost tourism in Switzerland, the government commissioned Riggenbach to build a rack railway up Rigi Mountain. Following the construction of a prototype locomotive and test track in a quarry near Berne, the Vitznau-Rigi-Bahn opened on 22 May 1871.
The Riggenbach system is similar in design to the Marsh system. It uses a ladder rack, formed of steel plates or channels connected by round or square rods at regular intervals. The Riggenbach system suffers from the problem that its fixed ladder rack is more complex and expensive to build than the other systems. Common structural shapes Following the success of the Vitznau-Rigi-Bahn, Riggenbach established the Maschinenfabrik der Internationalen Gersellschaft fur Bergbahnen (IGB) - a company that produced rack locomotives to his design.
The Strub rack system was invented by Emil Strub in 1896. It uses a rolled flat-bottom rail with rack teeth machined into the head approximately 100 mm apart. Safety jaws fitted to the locomotive engage with the underside of the head to prevent derailments.
The best-known use of the Strub system is on the Jungfraubahn in Switzerland. It is the simplest rack system to maintain and has become increasingly popular.
The Abt system was devised by Roman Abt, a Swiss locomotive engineer. Abt worked for Riggenbach at his works in Olten and later at his IGB rack locomotive company. In 1885 he founded his own civil engineering company.
During the early 1880s, Abt worked to devise an improved rack system that overcame the limitations of the Riggenbach system. In particular, the Riggenbach rack was expensive to manufacture and maintain and the switches were complex. In 1882 Abt designed a new rack using solid bars with vertical teeth machined into them. Two or three of these bars are mounted centrally between the rails, with the teeth offset. The use of multiple bars with offset teeth ensures that the pinions on the locomotive driving wheels are constantly engaged with the rack. The Abt system is cheaper to build than the Riggenbach because it requires a lower weight of rack over a given length. However the Riggenbach system exhibits greater wear resistance than the Abt.
The first use of the Abt system was on the Harzbahn in Germany which opened in 1885.
The pinion wheels can be mounted on the same axle as the rail wheels (as in the picture at right), or driven separately. The steam locomotives on the Mount Lyell Mining and Railway Company had separate pistons driving the pinion wheel.
The Locher rack system, invented by Eduard Locher, has gear teeth cut in the sides rather than the top of the rail, engaged by two cog wheels on the locomotive. This system allows use on steeper grades than the other systems, whose teeth could jump out of the rack. It is used on the Pilatus Railway.
Locher set out to design a rack system that could be used on gradients as steep as 1 in 2 (50%). The Abt system - the most common rack system in Switzerland at the time - was limited to a maximum gradient of 1 in 4 (25%). Locher showed that on steeper grade, the Abt system was prone to the driving pinion over-riding the rack causing potentially catastrophic derailments, as predicted by Dr. Abt. To overcome this problem and allow a rack line up the steep sides of Mt. Pilatus, Locher developed a rack system where the rack is a flat bar with symmetrical, horizontal teeth. Horizontal pinion engage the centrally-mounted bar, both driving the locomotive and keeping it centered on the track.
Following tests, the Locher system was deployed on the Pilatus Railway which opened in 1889. No other public railway uses the Locher system, although some European coal mines use a similar system on steeply graded underground lines.
The Lamella system (also known as the Von Roll system) was developed by the Von Roll company after the rolled steel rails used in the Strub system became unavailable. It is formed from a single blade cut in a similar fashion to the Abt system but typically wider than a single Abt bar. The Lamella rack can be used by locomotives designed for use on the Riggenbach or the Strub systems and some railways use rack from multiple systems. The St. Gallen Gais Appenzell Railway in Switzerland has sections of Riggenbach, Strub and Lamella rack.
Most of the rack railways built from the late 20th century onwards have used the Lamella system.
Originally almost all cog railways were powered by steam locomotives. The steam locomotive needs to be extensively modified to work effectively in this environment. Unlike a diesel locomotive or electric locomotive, the steam locomotive only works when its powerplant (the boiler, in this case) is fairly level. The locomotive boiler requires water to cover the boiler tubes and firebox sheets at all times, particularly the crown sheet, the metal top of the firebox. If this is not covered with water, the heat of the fire will soften it enough to give way under the boiler pressure, leading to a catastrophic failure.
On rack systems with extreme gradients, the boiler, cab and general superstructure of the locomotive are tilted forward relative to the wheels so that they are more or less horizontal when on the steeply graded track. These locomotives often cannot function on level track, and so the entire line, including maintenance shops, must be laid on a gradient. This is one of the reasons why rack railways were among the first to be electrified and most of today's rack railways are electrically powered.
On a rack-only railroad locomotives always push their passenger cars for safety reasons since the locomotive is fitted with powerful brakes, often including hooks or clamps that grip the rack rail solidly. Some locomotives are fitted with automatic brakes that apply if the speed gets too high, preventing runaways. Often there is no coupler between locomotive and train since gravity will always push the passenger car down against the locomotive. Electrically powered vehicles often have electromagnetic track brakes as well.
The maximum speed of trains operating on a cog railway is generally very low, about 25 km/h.

Points of Interest:
- See an unusual geologic feature – a chert shut-ins, cliffs and wet-weather waterfall.
- Enjoy a scenic Ozark creek with chert boulders and a large shelter cave.
Natural Features Description: Solid beds of chert such as this are uncommon and here the chert is 40 feet thick. This chert, unlike the common chert rocks found throughout the Ozarks, is completely silicified forming these massive beds. Shut-ins occur where a broader stream is "shut in" to a narrow canyon-like valley. Shut-ins typically occur in Missouri where streams flow through softer sedimentary bedrock materials such as dolomite or sandstone and then encounter a more resistant rock, in this case chert. Chert is composed of silica dioxide and is highly resistant to weathering.
This area is very scenic, especially after a rain when water cascades down over a 10 feet tall waterfall and through a chert shut-in stream. A spring-fed creek keeps water flowing to some degree through the shut-in typically six to eight months of the year. The chert cliffs support a number of lichens and mosses as well as a few hardy fern species such as hairy lip fern. The name "Cowards Hollow" is thought to have been derived from local legend that the area's shelter cave was used as a hideout from Civil War deserters.
This natural area is within the Mark Twain National Forest. From Doniphan, take Highway 160 west to Highway C. Go north on C for 13 miles. Turn left (west) on to Forest Service Road 3142 (gravel). Head west for 2.5 miles. Turn right (north) on to Forest Service Road 4875. Travel 0.3 mile and park. Walk the trail to the north crossing under the powerline and into the natural area. A map and compass are recommended to explore this area. Hunting and fishing are permitted.

Airport Maintenance Hangar Construction
1. Project Overview
The project is divided into three phases with a total construction land area of 81,384.1 square meters. The construction land is about 336 meters long from east to west and about 227 meters wide from north to south (partially 108 meters). The new structures of the hangar project include the maintenance and painting of hangars and annexes, power stations, dangerous goods warehouses, waste warehouses, gatehouses, and outdoor works.

2. International airport BIM model
In the picture above the aircraft painting hall of the maintenance aircraft hangar of the international airport, since the building span here is 123 meters, the roof adopts a two-layer oblique quadrangular pyramid space frame. The resulting problem is: there are relatively dense and large-sized air ducts in the air above the aircraft painting hall. How to ensure that the space frame will not collide with the ventilation system after the overall hoisting has become the problem that this project needs to solve. important question.
In the establishment of the BIM model, follow the principle of avoiding the large by using the small, making full use of the gaps in the space frame, and arranging the system with a large size first, and then arranging the system with a small size. Fully communicate and coordinate with structural designers and HVAC designers, integrate and eliminate unnecessary components as much as possible under the conditions allowed by the regulations, and finally achieve zero collision between the space frame and the ventilation system, and reduce the construction cost by 8%.
