Quick Answer: Does Tile Adhesive Colour Matter?
How long after adhesive can I grout?
24 hoursYou should wait at least 24 hours before grouting the tiles.
Don't be fooled by this.
Can I use tile adhesive instead of mortar?
Which cement is best for floor tiles?
but OPC 53 cement have high strength comparison to 43 grade of cement but it is used in RCC work. For tile fixing like flooring tile and wall tiles I recommended go through the use of 43 grade of cement.
Does ready mixed tile adhesive go off?
The shelf life on tile adhesives is usually around 6-12 months, depending on the type of adhesive you are using (ready-mixed or powder). … The reason adhesive has a shelf life is because it might begin to set over time (whether opened or not).
What is the best tile adhesive for large tiles?
Simple! choose a good quality powdered adhesive, preferably a polymer modified one such as granfix fastset flexible. To explain the advice above consider that in general, tile adhesive can be split into 2 types; ready mixed and powdered.
What is the difference between white and GREY tile adhesive?
For this reason white tile adhesive is usually used for fixing wall tiles, as it's more often than not subsequently grouted in a light colour. Using a grey mortar, with possible contaminants, is liable to cause unsightly discolouration to either the porous natural stone or the grouting itself.
How thick should the tile adhesive be?
1. Apply the adhesive to the surface with an appropriate notch trowel: as a general guide use a 6mm notch trowel to achieve a 1mm bed thickness for walls; 10mm notch to achieve an approximate 1.5mm bed thickness for concrete floors; 12mm notch trowel to achieve a 2.5mm bed thickness for timber floors.
Can you put adhesive on tile?
Try not to work on more than one square metre at a time, as the adhesive could start hardening before you've put all the tiles in place. Choose a suitable tile adhesive for your tiles: for ceramic tiles use a ready-mixed tile adhesive or powder adhesive and a powder tile adhesive for porcelain tiles.
What is the difference between tile adhesive and grout?
Tile adhesive and grout is used for bonding and sealing tiles. Tile adhesive is applied first to fix tiles to wall or floor surfaces. Grout, also known as grout sealer, is applied afterwards to fill in gaps and seal tiles by affectively forming a fluid concrete.
Can we mix cement with tile adhesive?
Cement can be used as an adhesive and is used as a base material in many commercial tile adhesive products. Tiles can be laid bonded with adhesive, so cement can be used, however mixing cement and adhesive, as implied in the question, is a matter of trial and error and has questionable merit.
Which adhesive is best for tiles?
MYK LATICRETEMYK LATICRETE® Tile Adhesive is a factory made cementitious dry powder which is mixed with water or special liquid additive to form a paste, providing problem-free, full bedding tile/stone installation. MYK LATICRETE® thin-set adhesives have high bonding strength allowing the tiles to directly fixed to the substrate.
Can I use tile adhesive to level floor?
Thick Bed FlexiRapid is a pourable and flexible rapid setting cement based floor tile adhesive. … It is ideal for fixing tiles of uneven thicknesses, for fixing to uneven surfaces and it can also be used to level uneven floors.
Should you wet tiles before laying?
Why Tiles Are Soaked In Water Before Installation The purpose of soaking tile before laying is to make the pores fully absorb water, so as not to cause hollowing, shedding, or even cracks. … Especially for the wall paving, before the wall tiles laying, it is necessary to sprinkle water on the wall.
How long does tile adhesive take to set?
approximately 24 hoursTile adhesive dries in a way that is very similar to concrete. The substance starts out as a powder and then, when mixed with water, it becomes a substance with a thick consistency. Under normal circumstances, you will need to let it dry for approximately 24 hours after installation before you can walk on the tile.
What is the difference between floor adhesive and wall adhesive?
Although it has worked well for some people, the real answer to this question is no. Unlike floor tile adhesives, you can only use wall tile adhesives for holding tiles on a vertical surface. The floor tile adhesive is strong and can withstand horizontal pressure as people move.
What adhesive will stick to ceramic tile?
Is ready mixed tile adhesive any good?
Ready-mixed is generally easier to use, but it has limitations attached to it. Here at Dunlop, we would never recommend using a ready-mixed product when using porcelain, large-format tiles and tiling floors, or wet areas.
Which is better tile adhesive or cement?
Laying tiles by using tile adhesive with notched trowel requires less amount of material. Adhesive layer is a lot thinner than the mixture of sand-cement, and this leads to lighter load to building structure. A bag of 20 kg tile adhesive can be used to lay tiles on the average area of 4 – 5 m2.
Can I use adhesive instead of grout?
Dispersion adhesive will not be fine used as a grout it will let water pass through it and offer no resistance. the water will then pass in to the sub-straight and start to damage it. if you leave it uncorrected in 6 months time you will have big problems so remove the adhesive and use grout.
Can you lay tile and grout in the same day?
You should wait at least 24 hours before grouting the tiles. You may notice that the edges of the thinset or the thinset showing through the grout lines looks dry. The thinset under the tiles isn't receiving as much air as the edges and is therefor not fully cured.

Resumé
Potential near-well mineralogical changes caused by seasonal high temperature aquifer thermal storage were investigated by numerical reactive transport modelling for two mineralogically different Danish geothermal reservoirs; the mineralogical mature and calcite free Gassum Fm. and the calcite containing Bunter Sandstone Fm. Modelling scenarios simulated injection of heated formation water with temperatures up to 150 °C into the reservoirs for a period of 6 months. For the Bunter Sandstone Fm., the formation water was modified to a saturation index for calcite of −0.1 prior to injection to replicate a situation where precautions are made to avoid loss of injectivity due to calcium carbonate scaling at elevated temperatures. Based on mineral dissolution and precipitation calculated by the numerical model, the changes in porosity as a result of heat storage were estimated. For the Gassum Fm., no significant changes in porosity were calculated when injecting formation water with temperatures up to 100 °C. At temperatures ≥120 °C, the content of albite and siderite was significantly reduced due to dissolution, but these mineralogical changes were not expected to significantly affect the reservoir porosity due to the low content of these minerals in the reservoir. However, significant precipitation of calcite near the injection well at temperatures ≥120 °C may reduce injectivity at these temperatures. For the calcite containing Bunter Sandstone Fm., injection of the slightly modified formation water led to significant calcite dissolution in the reservoir at all investigated temperatures and to dolomitisation at 150 °C. In the case of dolomitisation, our results suggest a risk for clogging of the near well environment by freshly precipitated dolomite. For the remaining temperatures, the calcite dissolution causes an increased porosity and a potential risk for compromising the rock integrity which should be further investigated. For both reservoirs, only very small changes were predicted in the aqueous composition of the formation water. The mineralogical changes in the reservoir are therefore not easily detected by monitoring changes in the aqueous composition of the formation water. Our results imply that high temperature aquifer thermal energy storage in reservoirs with a high calcium carbonate content such as the Bunter Sandstone Fm. is challenging. If precautions are taken to avoid calcium carbonate scaling by reducing the calcium content of the formation water, injection of the Ca-depleted formation water into the reservoir will cause dissolution of calcium carbonates. On the other hand, if precautions are not taken, it is well-known that precipitation of calcium carbonates will cause scaling and clogging problems. In contrast, our results suggest that storage of excess heat in mineralogical mature and calcite free sandstones such as the Gassum Fm. may be feasible. This is especially the case at temperatures <100 °C.

Dear Sirs, 2008
Nintendo DS, custom coded game, R4 card
Dear Sirs is a mobile poem—a workplace related resignation poem and marking of time using mesostics and numeric references to embed secret locative information within the poem on a Nintendo DS. Dear Sirs is a part of a series of works that are all interactive game like poems that exploit the relationship between the user, the hardware, the physicality of the user and the interface. Through visuals, text and interaction the poems circumvent and explore poetic/textual conventions and human empathy in a technological context. The participant is required to mark time along with the poet in order to experience the poem. For each stroke on the touch screen with the stylus—one letter of the poem is sequentially revealed. Referencing the famous poem "What you say" by John Cage, this work uses mesostics and embedded numbers to reveal a location—both virtual and physical, and a rejection of participation in problematic systems.

Unusual Competition of Extreme Ironing
Extreme Ironing (also called EI) is an extreme sport and a performance art in which people take an ironing board to a remote location and iron items of clothing. Extreme ironing is "the latest danger sport that combines the thrills of an extreme outdoor activity with the satisfaction of a well-pressed shirt."
This can involve ironing on a mountainside, preferably on a difficult climb, or taking an iron skiing, snowboarding or canoeing. Beginners usually start extreme ironing in the safety of their back gardens, although some daring members have been known to go straight to the mountain. Despite it's superficial danger, extreme ironists always take numerous safety measures, including safety ropes, harnesses, spare irons and the like.
History : Extreme Ironing was first started in 1997 by Leicester man, Philip Shaw, when Philip decided to do his ironing in the back garden. Since then, extreme ironing has developed into a sport that has attracted and give attention around the world. Shaw came home from what he recalls as a hard day in a Leicester knitwear factory. Preferring the idea of an evening out rock climbing, he decided to combine the two activities and convert it into a new extreme sport.
In June 1999, Shaw, who uses the nickname "Steam", embarked on an international tour to promote the activity. The stops included United States, Fiji, New Zealand, Australia and South Africa. An encounter with German tourists in New Zealand led to the formation of a group called "Extreme Ironing International" and the German Extreme Ironing Section (GEIS).
The "sport" gained international attention after a documentary entitled Extreme Ironing : Pressing for Victory, was produced for Britain's Channel 4 by Wag TV and From then it becomes the unusual competition of Extreme Ironing.

action integral is:
 S = \int {1\over 2} \partial_\mu \phi \partial^\mu \phi d^dx \,.
The probability amplitude for a process is:
 \int_A^B e^{iS} D\phi\,,
where A and B are space-like hypersurfaces that define the boundary conditions. The collection of all the \,\phi(A) on the starting hypersurface give the initial value of the field, analogous to the starting position for a point particle, and the field values \,\phi(B) at each point of the final hypersurface defines the final field value, which is allowed to vary, giving a different amplitude to end up at different values. This is the field-to-field transition amplitude.
The path integral gives the expectation value of operators between the initial and final state:
 \int_A^B e^{iS} \phi(x_1) ... \phi(x_n) D\phi = \langle A| \phi(x_1) ... \phi(x_n) |B \rangle\,,
and in the limit that A and B recede to the infinite past and the infinite future, the only contribution that matters is from the ground state (this is only rigorously true if the path-integral is defined slightly rotated into imaginary time). The path integral should be thought of as analogous to a probability distribution, and it is convenient to define it so that multiplying by a constant doesn't change anything:
 {\int e^{iS} \phi(x_1) ... \phi(x_n) D\phi \over \int e^{iS} D\phi } = \langle 0 | \phi(x_1) .... \phi(x_n) |0\rangle \,.
The normalization factor on the bottom is called the partition function for the field, and it coincides with the statistical mechanical partition function at zero temperature when rotated into imaginary time.
The initial-to-final amplitudes are ill-defined if one thinks of the continuum limit right from the beginning, because the fluctuations in the field can become unbounded. So the path-integral should be thought of as on a discrete square lattice, with lattice spacing a and the limit a\rightarrow 0 should be taken carefully. If the final results do not depend on the shape of the lattice or the value of a, then the continuum limit exists.
On a lattice ... [edit]
On a lattice, (i), the field can be expanded in Fourier modes:
\phi(x) = \int {dk\over (2\pi)^d} \phi(k) e^{ik\cdot x} = \int_k \phi(k) e^{ikx}\,.
Here the integration domain is over k restricted to a cube of side length 2\pi/a, so that large values of k are not allowed. It is important to note that the k-measure contains the factors of 2\pi from Fourier transforms, this is the best standard convention for k-integrals in QFT. The lattice means that fluctuations at large k are not allowed to contribute right away, they only start to contribute in the limit a\rightarrow 0. Sometimes, instead of a lattice, the field modes are just cut off at high values of k instead.
It is also convenient from time to time to consider the space-time volume to be finite, so that the k modes are also a lattice. This is not strictly as necessary as the space-lattice limit, because interactions in k are not localized, but it is convenient for keeping track of the factors in front of the k-integrals and the momentum-conserving delta functions that will arise.
On a lattice, (ii), the action needs to be discretized:
 S= \sum_{<x,y>} {1\over 2} (\phi(x) - \phi(y) )^2\,,
where <x,y> is a pair of nearest lattice neighbors x and y. The discretization should be thought of as defining what the derivative \partial_\mu \phi means.
In terms of the lattice Fourier modes, the action can be written:
S= \int_k ( (1-\cos(k_1)) +(1-\cos(k_2)) + ... + (1-\cos(k_d)) )\phi^*_k \phi^k\,.
For k near zero this is:
S = \int_k {1\over 2} k^2 |\phi(k)|^2\,.
Now we have the continuum Fourier transform of the original action. In finite volume, the quantity d^dk is not infinitesimal, but becomes the volume of a box made by neighboring Fourier modes, or (2\pi/V)^d.
The field \,\phi is real-valued, so the Fourier transform obeys:
 \phi(k)^* = \phi(-k)\,.
In terms of real and imaginary parts, the real part of \,\phi(k) is an even function of k, while the imaginary part is odd. The Fourier transform avoids double-counting, so that it can be written:
 S = \int_k {1\over 2} k^2 \phi(k) \phi(-k)
over an integration domain that integrates over each pair (k,−k) exactly once.
For a complex scalar field with action
 S = \int {1\over 2} \partial_\mu\phi^* \partial^\mu\phi d^dx
the Fourier transform is unconstrained:
 S = \int_k {1\over 2} k^2 |\phi(k)|^2
and the integral is over all k.
Integrating over all different values of \,\phi(x) is equivalent to integrating over all Fourier modes, because taking a Fourier transform is a unitary linear transformation of field coordinates. When you change coordinates in a multidimensional integral by a linear transformation, the value of the new integral is given by the determinant of the transformation matrix. If
 y_i = A_{ij} x_j\,,
then
\det(A) \int dx_1 dx_2 ... dx_n = \int dy_1 dy_2 ... dy_n\,.
If A is a rotation, then
A^T A = I
\,
so that \det A = \pm 1, and the sign depends on whether the rotation includes a reflection or not.
The matrix that changes coordinates from \,\phi(x) to \,\phi(k) can be read off from the definition of a Fourier transform.
 A_{kx} = e^{ikx} \,
and the Fourier inversion theorem tells you the inverse:
 A^{-1}_{kx} = e^{-ikx} \,
which is the complex conjugate-transpose, up to factors of 2\pi. On a finite volume lattice, the determinant is nonzero and independent of the field values.
 \det A = 1 \,
and the path integral is a separate factor at each value of k.
 \int
\exp \biggl({i \over 2} \sum_k k^2 \phi^*(k) \phi(k) \biggr) D\phi = \prod_k \int_{\phi_k} e^{{i\over 2} k^2 |\phi_k|^2 d^dk} \,
The factor \scriptstyle d^dk is the infinitesimal volume of a discrete cell in k-space, in a square lattice box \scriptstyle d^dk = {1/L}^d, where L is the side-length of the box. Each separate factor is an oscillatory Gaussian, and the width of the Gaussian diverges as the volume goes to infinity.
In imaginary time, the Euclidean action becomes positive definite, and can be interpreted as a probability distribution. The probability of a field having values \phi_k is
 e^{\int_k - {1\over 2} k^2 \phi^*_k \phi_k} = \prod_k e^{- k^2 |\phi_k|^2 d^dk}
The expectation value of the field is the statistical expectation value of the field when chosen according to the probability distribution:
\langle \phi(x_1) ... \phi(x_n) \rangle = { \int e^{-S} \phi(x_1) ... \phi(x_n) D\phi \over \int e^{-S} D\phi}
Since the probability of \,\phi_k is a product, the value of \,\phi(k) at each separate value of k is independently Gaussian distributed. The variance of the Gaussian is 1/ (k^2 d^dk), which is formally infinite, but that just means that the fluctuations are


Delving deep into Data 'Black Hole' requires a Powerful Spotlight
As Central Banks develop their thinking and understanding around the creation of Data Strategies in which large amounts of banknote data are translated into meaningful information, experienced software development firm 7 Layer says important insights are available with the right approach.
The banknote equipment environment can appear daunting. Mixed fleets of machines collecting data at an enormous rate, each storing the data in different locations, formats and versions and over many years, can start to look overwhelming.
"This infamous data "black hole", just like light into an actual black hole, takes data in but emits nothing. To extract that data and uncover insights from it is a matter of applying the right technology, and with NoteChain® we now have the software to start exploring massive amounts of data quickly and efficiently," says Phil Ball, Technical Director at 7 Layer and an expert in data analytics when applied to the cash logistics industry.
"Defining what the Bank needs from the data and, therefore, defining the questions to be answered, is the key to translating data into meaningful information," says Mr. Ball. "Once it is clear what information the Bank is specifically seeking, we are in a position to use the advanced tools that are now available to us to process this data at an enormous scale."
Identifying the questions that need to be answered ultimately leads to evidence-based decision making. It is the basis of a Data Strategy, which becomes the blueprint for the approach a Bank takes to drive improvements in all aspects of its currency management program.
"To create the information needed to give Central Banks full command over their currency management system, reading banknote serial numbers is key. Once we can track an individual banknote, we can connect it to all its sensor data. We can then make sense of literally billions of data points across a currency system," says Mr. Ball.
"Besides answering the right questions, powerful data analytic software can also uncover hidden patterns, unknown correlations, trends, previously unobserved customer behaviours and other useful information."
NoteChain® is designed to do exactly this. Sensor data (with serial numbers) is collected from a wide and varied range of machines in different formats, it is cleansed and de-duplicated, then run through a series of customised algorithms that translate this raw data into the requested information in the form of a customer-defined dashboard.
The visualisations are carefully designed to be straightforward and easy to understand. They are developed to answer specific questions relevant to currency management including optimising demand and supply, the specification of the banknote and the performance of the banknote in circulation.
Says Mr. Ball, "Another issue is to unearth so-called good data which is considered to be not only consistent, but sufficient to answer the right questions and efficient to gather."
In applying NoteChain® to a currency system, besides ensuring that the Bank owns the data itself, the practicalities of setting up the right approach to access and bring together good data depend on a number of factors, including:
 - how many physical sites are part of the network
 - the mix of banknote equipment being used
 - third parties who are handling the banknotes at different points in the system, and
 - understanding any Notes Held to Order used
NoteChain® is the world's only data analytic platform designed specifically for end-to-end currency management. It provides accurate, bespoke banknote currency performance insights that can only be accessed via the computational power of this data analytic solution.

This week, NILU welcomed the partners from the Polish GIOS, Chief Inspectorate of Environmental Protection, to Kjeller.
Over the course of three days, NILU researchers from several departments have shared insights and experiences that contribute to the ongoing collaborative project "Strengthening of atmospheric deposition assessment in Poland based on Norwegian experience".
Of particular interest to the Polish partners was how NILU carries out monitoring and assessment of the deposition of air pollution in Norway and Europe. In addition, a comprehensive tour of NILU's chemical laboratories as well as an exclusive visit to the Birkenes Observatory in Agder were included in the program (see picture above).
The first day of the visit began with a presentation of NILU by Deputy CEO Ole-Anders Braathen. Among other things, the EBAS database was highlighted as a valuable international resource that is openly accessible to all.
Furthermore, project manager Barbara Toczko (pictured below) gave a summary of the activities in the project:
- Developing the concept of revision and optimization of deposition measurements in Poland (NILU lead: Wenche Aas, ATMOS)
- Developing the concept of launching the quality assurance / quality control (QA/QC) system for deposition measure (NILU lead: Helene Lunder Halvorsen, MILK)
- Developing the guidance document on assessment of atmospheric deposition, including a proposal of the most suitable deposition modeling technique (NILU lead: Joana Soares, IMPACT)
- Visualisation and making available of atmospheric deposition data via the web site "Air Quality" CIEP (NILU lead: Rune Åvar Ødegaard, DIGITAL)
- Procurement of deposition measurement instruments
- Project management and promotion activities (see _URL_

How do products get properly spaced for weighing or labeling?
You need to use a box/case indexer. Proper product spacing is vital to ensuring reliable operation of downline equipment such as conveyor scales, checkweighers and labeling systems.
Conveyor Scale – proper product spacing ensures only one package is on the scale at a time. If two packages are simultaneously on the scale, an incorrect weight can result.
Checkweigher – A checkweigher is essentially a conveyor scale with a divert so the same incorrect weight situation will arise as with a conveyor scale. However, the divert may reject a package that is actually within the proper weight range.
Labeling System – Proper product spacing ensures that labels can be formatted, printed and applied to the box before the next one arrives.
So how exactly does an indexer work?
Importance of a Indexer for Proper Box Spacing-1
A supply conveyor transports boxes with inconsistent spacing. The boxes move onto the Indexer, which has a conveyor section that will drop down allowing boxes to accumulate against a Bulkhead. (This conveyor section has unique roller belting that allows the conveyor to continuously turn while boxes accumulate on top of the belt.)
Importance of a Indexer for Proper Box Spacing-2
A sensor (not shown) detects a space is available, the Drop Down Conveyor section will then rise allowing a box to advance unobstructed. The Infeed Conveyor, which moves faster than the Drop Down Conveyor, will grab the first box (A) propelling it forward to create a gap between the trailing box (T).
Importance of a Indexer for Proper Box Spacing-3
The Drop Down Conveyor will quickly lower again causing the boxes to accumulate against the bulkhead. Once the sensor (not shown) detects a gap, the indexer will rise, once again, and let another box advance. This is how an Indexer controls box spacing to ensure only one box is on the scale at a time.
Conclusion: Indexers are vital product handling equipment that can make your entire operation more efficient and reduce manual labor.

Primal Earth is a chunk of pure earthly essence. It is used in a wide range of high-end recipes.
-Transmute: Primal Fire to Earth
-Transmute: Primal Life to Earth
Primal Earth is primarily made by converting 10 Motes of Earth to one Primal Earth. Motes of Earth can typically be found by Miners, from Fel Iron, Adamantite, and Khorium veins. They can also be recovered from various Earth elementals in Outland (Enraged Crushers in Nagrand, Enraged Earth Spirits in Shadowmoon Valley, etc.).
Primal Earth can be created through Alchemy with the Transmute: Primal Fire to Earth and Transmute: Primal Life to Earth recipes.
Primal Earth is one of the cheapest primals due to its relative abundance and the fact that (unlike Shadow, Mana, Fire, Life, and Water) it is not used in any of the Tailoring cloths.
Primal Earth as an ingredientEdit
Primal Earth is used in the following recipes:


indexes or not.).
- When there is a global index, the situation is much more complicated. Assuming that each table has three global indexes, the size of the execution plan space will roughly become (3x3) x (2x3) x (1x3)=162, and the complexity will rise sharply. Accordingly, the requirements for the optimizer will be much higher. The optimizer needs to consider more statistics to select a better execution plan; More pruning is needed to complete query optimization in a shorter time.
So we can see that in the "distributed database" or some middleware products without global indexes, the optimizers are very weak, most of them are RBO, they do not need a powerful optimizer at all, and more optimization content is actually replaced by the stand-alone optimizer.
Implement strong consistency and high-performance distributed transactions on MySQL
In order to build a transparent distributed database, the key is the global index and the distributed transactions that the global index depends on. The exploration in the middleware era has told us that to make strong, consistent and high-performance distributed transactions, we must make deep modifications to the storage (MySQL).
We choose the scheme of using global MVCC (TSO)+2PC (XA).
Start is included in the stand-alone MVCC of MySQL_ timestamp (that is, trx_id in MySQL). In order to achieve global MVCC, several core things need to be done:
- Provide a global timestamp generator TSO, _URL_ 。
- Replace stand-alone trx with TSO generated global timestamp_ id。
- Introduce commit_ Timestamp (also generated by TSO), using strat_ timestamp and commit_ It is very efficient to judge the visibility by timestamp, _URL_ 。 The costly scheme of exchanging active transaction lists or GTMs between nodes is not used.
Transaction flow in PolarDB-X:
The modification of the record format in InnoDB is called the Lizard transaction system. See the following for details:
We also have some other articles to introduce the implementation of PolarDB-X distributed transactions:
- PolarDB-X Strong Consistent Distributed Transaction Principle
- Implementation of PolarDB-X distributed transaction (I)
With distributed transactions and global indexes, PolarDB-X has officially transformed from a middleware into a distributed database.
Transparent distribution of PolarDB-X
PolarDB-X implements excellent distributed transactions and global indexes, which meet the requirements for global indexes mentioned above and achieve transparent distribution.
In the transparent distributed mode (mode='auto' is specified in CREATE DATABASE), all indexes are global indexes, and the application does not need to care about the partition key.
For example, our table creation statement is completely consistent with the stand-alone MySQL, and it does not need to specify the partition key:
create table orders (
id bigint,
buyer_ Id varchar (128) comment 'Buyer',
seller_ Id varchar (128) comment 'Seller',
primary key(id),
index sdx(seller_id),
index bdx(buyer_id)
)
Creating a global index is also consistent with the experience of creating a secondary index on a stand-alone MySQL. The whole process is online:
CREATE INDEX idx_ seller_ id ON orders (seller_id);
PolarDB-X's global index is strongly consistent, and its data consistency experience is not significantly different from that of stand-alone MySQL. It provides an isolation level between RC and RR that conforms to MySQL semantics.
At the same time, PolarDB-X has also done a lot of work on index maintenance and optimizer to ensure that the index can be created and maintained efficiently, and the optimizer can correctly generate the execution plan using the index.
The partition algorithm of PolarDB-X can also deal with hot spots, data skew and other problems in the index. Refer to: _URL_
Automatically (transparently) determine the lower limit and manually determine the upper limit
Divide common distributed databases on the market by transparency and manual:
- Typical representatives of transparent distributed databases: TiDB, CockroachDB.
- Typical representatives of manual distributed databases: OceanBase, YugabyteDB.
Is transparent distributed data better than manual data?
For databases that only provide transparent usage, the migration cost will be lower and the initial experience will be better. However, after entering the deep-water area, due to the inevitable use of a large number of distributed transactions, the performance in the core scenarios often fails to meet the requirements (or the same performance requires higher costs), and there is a lack of optimization methods such as eliminating distributed transactions and more sufficient computing push down.
For databases that only provide manual usage, although well-designed partitioning keys enable optimal performance in theory, the threshold for use will increase significantly (10% of core tables need to be designed for partitioning keys, and the remaining 90% of non core tables need to be designed for partitioning keys).
We believe that both transparent and manual distributed databases can not meet the requirements of businesses for both cost and performance.
PolarDB-X not only provides a transparent mode, but also fully supports the syntax of partitioned tables. It also provides Join Group/Table Group, partition online change and other tools to enable applications to push down more transactions and calculations to storage nodes when they need extreme performance.
PolarDB-X is the only distributed database on the market that can provide both transparent and manual modes. We recommend that most scenarios use the transparent mode, then perform pressure testing on core business scenarios, and manually optimize these scenarios using partition table syntax to achieve the highest performance.
Use Paxos protocol to achieve RPO=0
MySQL connected by middleware generally uses the active/standby architecture. The biggest problem with this method is that data will be lost, even if it takes a long time (walking along the river, you can't help wetting your shoes).
After years of science popularization in the database circle, we all know that some consistency protocols, such as Paxos and Raft, are required to avoid data loss. In fact, these agreements are no secret. Even the database circle has a joke that "students enrolled in schools should be able to hack Paxos".
The threshold is not the protocol itself, but the stability and performance of MySQL. Stability can only be obtained after large-scale verification and enough pits.
The Paxos protocol used by PolarDB-X is derived from Alibaba's internal X-Paxos. It can be said that there is no active/standby mode for Alibaba's internal MySQL databases, and 100% of them use X-Paxos. This means that it has experienced tens of thousands of MySQL clusters and various rapid verifications, and has high reliability.

Environmental Performance Reviews
Turkmenistan : First RevieweBook - 2012
"The first Environmental Performance Review of Turkmenistan covers 13 issues of importance to Turkmenistan related to policymaking, planning and implementation, the financing of environmental policies and projects and the integration of environmental concerns into economic sectors, in particular the sustainable management and protection of water resources, waste management, air pollution, forestry, biodiversity and protected areas, energy and climate change. The Environmental Performance Review Programme is considered an important instrument for countries within the UNECE Region. The second round, while taking stock of the progress made since the first cycle of reviews, puts particular emphasis on implementation, integration, financing and the socio-economic interface with the environment. Through the peer review process, EPRs also promote dialogue among UNECE member countries and harmonization of environmental conditions and policies throughout the region. As it is a voluntary exercise, an EPR is undertaken only at the request of the country concerned. The main outcome of the EPR is the recommendations, which were elaborated by the Expert Group, peer reviewed, discussed with a high-level delegation from Turkmenistan and adopted by the UNECE Committee on Environmental Policy on April 2012"--Provided by publisher.

Formation temperature is one of the most critical parameters in drilling and workover operation and it varies by true vertical depth of wellbore.
The following formula shows relationship between formation temperature and true vertical depth of well.
Formation temperature = (ambient surface temperature ) + (temperature gradient x Well TVD)
Formation temperature in F (Fahrenheit)
ambient surface temperature in F (Fahrenheit)
temperature gradient in F/ft (Fahrenheit / ft)
Well TVD in ft
Example: The temperature gradient in a specific area is 0.015 °F/ft of depth and the ambient surface temperature is 90 °F.
Determine the estimated formation temperature at a TVD of 12,000 ft:
Formation Temperature, °F = 90 °F + (0.015 °F/ft x 12,000 ft)
Formation Temperature, °F = 90 °F + 180 °F
Formation Temperature = 270 °F (estimated formation temperature)
Please find the Excel sheet used for estimating formation temperature.

Offending command: Put
The put command is too generic to allow for easy troubleshooting. You may have to check the page of general troubleshooting tips (a link is in the column in the left hand column).
 - PostScript errors caused by the PostScript command put are sometimes caused by custom fills. Check all drawings in your lay-out whether they contain custom files and either replace or recreate these.
 - "Put" errors may also be related to a damaged font. Reinstall all fonts used in your document from the original disks, both on your Mac or PC and your RIP. This is a known problem with Linotype PostScript level 1 RIPs when printing from FreeHand 7.
 - A PostScript error invalidaccess error, offending command put can be caused by the use of an incorrect driver. I once got around this error by switching from an Agfa PPD to a generic Scenicsoft PPD while creating PostScript code for Scenicsoft Preps. Using a PPD driver of a recent device for outputting on an older RIP can cause similar problems.
 - I once spend half a day troubleshooting a file from a customer that kept generating rangecheck errors, offending command put. It turned out that some of the about 20 spot colors in the file had round brackets in them (one colour was named 'bordeaux (tarif 1)') and this was unacceptable for the in-rip separation algorithm of the RIP. Changing the names of the spot colors solved the issue. The customer never experienced the problem himself because he always output preseparated files.
 - A rangecheck error, offending command put can occur while trying to print complex Xpress 3.3 files containing lots of nested EPS files (Illustrator files which contained other Illustrator EPS files which themselves contained EPS files of scanned images). Here are three solutions for this problem:
 1. Make a back-up copy of XPress and open this copy with ResEdit. Open the PSHD resource and look for line 1007. Use the search command to find the following piece of text: /A 128 array def. Change the 128 to a higher value (like 250 or even 500). Save the altered application and use it to print the file. Although this solution works, it may still generate the "rangecheck" error if you print lots of pages in one go.
 2. You can also send the file as a composite file and have the RIP do the separation. On Agfa RIPs, this workflow is called "Inrip separaration" or 'Composite printing'.
 3. Download the following piece of PostScript code to the Postscript level II RIP and then print your file. I cannot guarantee that this code works with non-Agfa RIPs.
true 0 startjob
userdict begin
/F18 /array load def
/array { dup 128 eq { pop 50000 } if F18 } bind def
This piece of code will remain active until the RIP is rebooted or reset. You can add it to user/boot but then the first line should not be included.


Homework Assignments
September 3
 - Exercise 1 - Make a copy of the Temperature3.c program (Fahrenheit to Celsius version 3) and modify it to print a header line that labels each column.
 - Exercise 2 - rewrite the program in Exercise 1 to run in Matlab.
 - Exercise 3 - rewrite the Matlab program that you developed for Exercise 3 in MTHSC 360 as a C program. However, I want you to go the extra step and insure that there are no empty lines, and no lines that start or end with a comma and a space.
 Here's a reminder of what the Matlab exercise entails:
 Write a program which examines the numbers from 1 to 100.
 If a number is divisible by three and by five, then the program should print "Orange and White" on a line by itself.
 If a number is divisible by three and not divisible by five, then the program should print "Orange" on the current line followed by a new line.
 If a number is not divisible by three but is divisible by five, then the program should print "White" on the current line followed by a new line.
 If a number is not divisible by three or by five, then the program should simply print the number. Numbers should be printed on the current line, and they should be separated by a comma and a space from any following numbers or words.
 As a bonus, can you insure that there are no empty lines, and no lines that start or end with a comma and a space.

4 Finds from 'Nobbs' (Knobbs Farm). Transferred (to Museum) 1865. These included Samian rim, Samian base, base of colour coated vessel, four sherds of the rim of a jar and rim sherd of a dish.


ADEDE wins UXO detection and beach clearance contract in Belgium
ADEDE was recently awarded the three year UXO detection and clearance contract for the Belgian coast by the Belgian Coast Authority (Afdeling Kust). Although a lot of effort was made to clear the Belgian beaches of UXO immediately after the last war, the volume of explosive and inert Remnants of War (ROW) was such that nowadays their number still pose a threat. The ongoing maintenance of sea defenses therefore implies that all intrusive activities, earthworks and construction needs to be preceded by geophysical surveys, detections and clearances of UXO, not in the least because of the shifting sediment resulting in migration of UXO from the sea towards the beaches. We are proud that our scientific, multidisciplinary and therefore costeffective approach towards solving UXO threats was recognised and we are looking forward to putting that into practice on the Belgium coastline for the next three years.

Payroll Administration
Payroll administration refers to the activities of payroll administrators to help employers better manage the payroll services for the company. The payroll administration process include keeping track and organizing company's employees payroll matters such as their total number of working hours, pay rates, bonuses or commissions that have been earned by employees. Payroll administrators often have to work with strict payment deadlines and comply with the Employment Act in Singapore. Following the salary and hour standards, the experienced administrators will need to ensure employees can get paid on time with right amount of money. Otherwise, the performance of the employees are likely to be affected that can result in low productivity for the business as inaccurate paychecks can cause them great inconvenience especially for foreign workers who need to provide for themselves financially in terms of the living expenses, rental fees and remittance of their wages to their families on a regular basis. Therefore, the roles of payroll administrators are very important as negligence due to carelessness or lack in knowledge not only can affect the productivity of employees but also implicate legal issues and disrupting business operations.
Payroll Administration Services Singapore - Time IS Money
Changes To Employment Act For Payroll matters
For instance, employers and payroll administrators need to understand and be mindful of any changes to Employment Act such as the new requirement from government to issue more detailed reports that includes itemised pay slips and key employment terms to their employees. This new directive which takes effect from 1 April 2016 is to let employees to have a better understanding of how their salary is calculated, their employment rights, terms and benefits. This can also help employers prevent and minimize any misunderstandings or disputes with their staff at the workplace.
Examples Of Itemised Items
1. Full name of employer
2. Full name of employee
3. Date of payment
4. Basic Salary (Rate of pay)
5. Start and end date of salary period
6. Allowances paid for salary period eg fixed allowances such as transport or ad-hoc allowances
7. Any other additional payment for each salary period eg Bonus, rest day pay, public, holiday pay
8. Deductions made for each salary period: All fixed deductions (employer's CPF contribution), all ad-hoc deductions (no-pay leave, absence from work)
9. Overtime hours worked
10. Overtime pay
11. Start and end date of overtime payment period
12. Net salary paid in total
Note: Please refer to Singapore Employment Act for detailed information. Failure to issue itemised pay slips, maintain detailed employment records or providing inaccurate information to the Commissioner for Labour can lead to serious civil breaches and administrative penalties.
Payroll Administrative Penalties Civil Breaches Singapore
Therefore, as payroll is an important and essential part of business operations, many businesses are recognizing the benefits and values of outsourcing payroll to an external payroll processing agency to avoid inaccuracies that can lead to serious consequences other than payroll errors. With access to effective payroll administration knowledge and advanced technology, payroll specialists from external payroll processing firms can help business owners save more money and better productivity by ensuring all tasks are completed on time with high accuracy.
Payroll Administrative Services For SME
It is understandable and common for new startups especially SME or small businesses, that the business owners would usually be the one handling all the payroll administrative work due to not having many employees initially. However, business owners will realise the importance of payroll administration when they start to hire more and more workers as the business grows. SME owners can wait until this blooming time to start having their human resource department look deeper into their payroll administration and management matters on setting up a proper payroll management system if cost is a concern initially. But having a outsourced payroll services will be more effective, efficient to business operation in the long run as besides the needs to maintain accuracy in pay and leave administration, other challenges include preparation of payroll taxes in facilitating Singapore employees report their personal income tax which can become overwhelming and lead to unforeseen miscalculation.
Payroll Administrator Roles & Responsibilities
In general, the roles and responsibilities of payroll administrators include the following activities:
 - verifying the total number of hours that employees have worked
 - verifying any additional allowances or bonus for current salary period such as overtime or pay increases
 - calculating and issuing salary according to company's practice which is usually by cheque, cash or electronic transfer
 - processing all fixed or ad-hoc deductions for each salary period such as no-pay leave, employee's cpf contribution
 - processing all holiday, sick and maternity claims and expenses
 - handling any queries regards to payslips
 - generating reports and tax submission
 - providing payroll support to new staff
 - processing necessary paperwork for leaving staff
 - other general administrative work

The Wise were a group of people among the various kindreds of the Children of Ilúvatar who had great knowledge and understanding of history and other lore. They were greatly respected, but always few in number. The Wise were both female and male; those who were female were sometimes referred to as Wisewomen.
The following people were often considered to be among the Wise:

Poplar Tree Elementary is incredibly proud of receiving this award, and know that this recognition is not the result of one or two individuals. This award is a result of outstanding teamwork. Our team consists of our fabulous staff who work hard and are committed to the students; our students who show perseverance when things are hard; and our parents who help support the learning at home. We firmly believe you can not achieve success in isolation and by working together great things happen for kids. So whether we are dealing with a Pandemic, technology issues, or a challenging math problem - we are all in this together and when we support each other great things happen!
Poplar Tree Elementary was one of the first schools in Fairfax County Public Schools (FCPS) to participate in the FCPSon program, assigning personal devices to all students and engaging instructional staff in professional development to help them weave technology into their classes. This technology—along with Project-Based Learning—resulted in a shift to a student-centered learning environment along with offering student leadership opportunities, such as the Paw Tech Squad, whose members support teachers and students with technology and even offer professional development. Teachers engage students in a balanced literacy framework for Language Arts, a workshop model for math, and a hands-on approach for science and social studies. Creative and critical thinking skills and problem-solving skills are encouraged by teachers across the curriculum. Learn more!
What are National Blue Ribbon Schools?
U.S. Secretary of Education Betsy DeVos today recognized 367 schools as National Blue Ribbon Schools for 2020. The recognition is based on a school's overall academic performance or progress in closing achievement gaps among student subgroups.
"Congratulations to this year's National Blue Ribbon School awardees," said Secretary DeVos. "It's a privilege to recognize the extraordinary work you do to meet students' needs and prepare them for successful careers and meaningful lives."
The coveted National Blue Ribbon Schools award affirms the hard work of educators, families, and communities in creating safe and welcoming schools where students master challenging and engaging content. Now in its 38th year, the National Blue Ribbon Schools Program has bestowed almost 10,000 awards to more than 9,000 schools, with some schools winning multiple awards. Schools are eligible for nomination after five years.
The Education Department recognizes all schools in one of two performance categories, based on all student scores, student subgroup scores and graduation rates:
- Exemplary High Performing Schools – These are among their state's highest performing schools as measured by state assessments or nationally normed tests.
- Exemplary Achievement Gap Closing Schools – These are among their state's highest performing in closing achievement gaps between a school's student groups and all students.
Up to 420 schools may be nominated each year. The U.S. Education Department invites National Blue Ribbon School nominations from the top education official in all states, the District of Columbia, Puerto Rico, the Virgin Islands, the Department of Defense Education Activity, and the Bureau of Indian Education. Private schools are nominated by the Council for American Private Education (CAPE).


Laser Cutting With Rayjet 300 & Adobe Illustrator
Introduction: Laser Cutting With Rayjet 300 & Adobe Illustrator
A method for cutting/engraving designs using Adobe Illustrator and the RayJet 300.
Step 1: Fire It Up!
Turn on the laser (switch is on the back of the machine) and place your stock material on the cutting table
Step 2: Import or Create a Design
While you can certainly create a design to laser within Illustrator, I decided to export a face from a part I was designing in Fusion 360 as a .dxf file. (Laser cutting your parts is WAY faster than 3D printing and can be WAY more accurate).
If you load in a design, make sure the scaling is "1:1" and the units match up. I tend to not center my imported parts because I often have to move them around anyway.
Step 3: Prepare Your Design
We need to adjust a few things on the design so that the laser behaves the way we want. Specifically, we need to make sure that the line color and stroke size are set in such a way that the laser's control software knows to cut along these lines--as opposed to engraving.
As pictured above, set your stroke color to Red and your stroke size to 0.03mm --the RayJet will only cut along "hairlines" such as 0.03mm
**Note, if you were both cutting and engraving within the same design, you would set any engraving line's stroke color to Black
Step 4: Export Your Design
Save your design as a PDF file and put it on a USB drive so that you can load it onto the computer acting as a control for the laser. (skip this step if you are designing and controlling the laser from the same machine)
Step 5: Send Design to Laser
Open you PDF file in Acrobat Reader. Click on "Print" and select the "Properties" button.
Step 6: Laser Properties
When you click on "Properties" a menu with many options appears. Make sure that the following are set:
-Material Thickness
Under the "Red" tab (you may add more tabs):
-Power 100%
-Speed 1% ...for engraving this can be faster, but cutting needs to be very slow.
If you were using multiple colors for different types of cut/engraving, you would adjust each accordingly. For example, if you needed to engrave Black lines you would switch the settings under it's tab to "engrave" "power: 90%", and "speed: 10%"
Step 7: Finalize Settings
In the next menu screen, the default settings tend to work well. Just make sure check the box for "Cutting Table" if you have one in.
Finally, look over the settings in the last menu screen and hit "Process" in the bottom right-hand corner to apply the setting to the job.
Lastly, hit "Print" back in Acrobat Reader and you're good to go!
Step 8: Enjoy the Magic of LASERS!

Earth from Space: The Tibesti Mountains
About this Image
The Tibesti Mountains, located mostly in Chad with the northern slopes extending into Libya, are captured in this image, acquired on March 4, 2012 by Envisat's MERIS instrument. The mountains' highest peak is Emi Koussi – pictured here as a circular structure in the lower-right portion of the dark area. The westernmost volcano is Toussidé. Our satellite view shows the dark peak with lava flows extending to the left. The white depression to the southeast gets its colour from the accumulation of carbonate salts, creating a soda lake. Surrounding the Tibesti Mountains, the sands of the Sahara appear like orange, yellow and white brushstrokes.

It appears that Netflix will be streaming this new series from 24 Jan 2020.
The docuseries will chronicle the Fall of Constantinople and the end of the Byzantine Empire from the Ottoman perspective.
In October 2018, Netflix greenlit the limited series titled 'Rise of Empires: Ottoman' which will chronicle the life of Mehmed the Conquerer and aims to tell the story of the Fall of Constantinople from a different perspective.
The first season, consisting of six episodes, will be released on Netflix on January 24, 2020.
The Turkish documentary series follows the rise of the Ottoman Empire under the leadership of Mehmed the Conquerer. In 1453 AD, at the age of 21, Sultan Mehmed conquered Constantinople (now Istanbul) and brought an end to the centuries-old Byzantine Empire.
After conquering the city, Sultan Mehmed transferred the capital of the Ottoman State from Edirne to Constantinople and established his court there.
The capture of the city (and two other Byzantine splinter territories soon thereafter) marked the end of the Roman Empire, a state which dated to 27 BC, which had lasted for nearly 1,500 years.
At home he made many political and social reforms, encouraged the arts and sciences, and by the end of his reign, his rebuilding program had changed the city into a thriving imperial capital. He is considered a hero in modern-day Turkey and parts of the wider Muslim world.
Cem Yigit Uzümoglu
Cem Yigit Uzümoglu is a Turkish actor known for his role as Emir in Netflix's 'The Protector'. He will play the role of Fatih Sultan Mehmet in the upcoming docuseries.
Tuba Büyüküstün is a Turkish actress known for her roles in 'Black Money Love' and 'Brave and Beautiful'. She will play the role of Mara Hatun, who was the stepmother of Sultan Mehmed. Born Mara Branković, she was the daughter of a Serbian monarch whose betrothal to Murad II was an attempt to prevent an invasion of Serbia from the Ottoman Empire.
Osman Sonant is a Turkish actor known for his work on 'Zengin ve Yoksul' and 'Ufak Tefek Cinayetler'. He plays the role of Loukas Notaras, a Byzantine statesman who served as the last megas doux or grand Duke and the last mesazon of the Byzantine Empire, under emperors John VIII Palaiologos and Constantine XI Palaiologos.

FEARS were raised for the health of the residents of Wales' only outpost last night, as a blanket of ash exerted a stranglehold on Patagonia.
Large swathes of the Argentinean region lay under a choking cloud of smoke and ash after the eruption of the long-dormant volcano of Chaiten in neighbouring Chile.
And the community, which retains strong Welsh links after being first settled 150 years ago, has experienced terrifying periods of "nuclear nights" when the pollution in the air has been so thick that it has blocked out the mid-afternoon sun. Earlier there were dramatic scenes, as ash was spewed 20 miles into the sky by the eruption.
In key Welsh Patagonian towns like Esquel and Trevelin, residents had to wear face masks whenever they went outside. Livestock were also beginning to die from breathing air and drinking water clogged with thick volcanic ash.
The area – known in Welsh as Y Wladfa – yesterday remained largely isolated from the outside world, with airports closed and roads opening sporadically because of the amount of ash on the road, up to 3cm deep in places.
Thousands of people were forced to evacuate from the towns of Chaiten and Futaleufu in Chile earlier this week after the volcano's first eruption in 9,000 years blew a thick column of ash eastward for hundreds of miles over Patagonia and Argentina to the Atlantic Ocean.
Patagonia is just half-an-hour's drive from the volcano.
"It looks like all the world like it has been snowing heavily – imagine a scene from the cartoon South Park," said Gill Stephen, a teacher from Cardiff who is currently teaching in Ysgol Gymraeg yr Andes (Andes Welsh School) as part of the Welsh Language Project established in 1997.
"In fact, it's a bit of a worry because it is pumice stone so it is quite abrasive and there are concerns for the health of people and animals that are breathing it.
"You can see in the flash of a camera that the air is thick with these particles – thicker than any fog you can imagine."
Residents of the larger towns in Patagonia – a region on the borders of Chile and Argentina to where 3,000 Welsh people emigrated between 1865 and 1912 – can still get water from the mains but thousands of litres of bottled water have been transported to smaller outlying towns and villages.
And the weekend's popular Eisteddfod de Trevelin, where opera star Rhys Meirion performed, took place under thick cloud and has already been dubbed "Eisteddfod y Llwch" (Eisteddfod of Dust).
Ms Stephen said she knew nothing of the eruption until white flakes began falling on her clothes as she waited for a bus on Friday morning in Esquel, a town popular with backpackers and skiers.
"I thought it had started snowing but when I got on to the bus they didn't melt and that's when I realised what it was," she said.
"It is an event that has taken everybody by surprise, nobody has seen anything like this before."
Experts are now waiting to see whether the volcano will affect the world's climate.
So far, Chaiten has emitted only a few thousand tons of sulphur dioxide.
In general, a volcano must spew at least one million tons of sulphur dioxide into the stratosphere to have a global effect on climate.
After eruptions of unusual size, sulphur dioxide, converted into sulphuric acid, can form a thin white cloud in the atmosphere that reflects sunlight away from Earth.
The Philippines' Mount Pinatubo produced a brief cooling of the climate after spewing 20 million tons of sulphur dioxide in 1991.
Luis Lara, a volcanologist with the Chilean government's Geology and Mining Service, said lava was rising within Chaiten without yet spilling over.
Atuel Williams, the former president of Eisteddfod de Trevelin, said streetlights were sometimes being lit during the day because of the artificial darkness.
"There is a lot of smoke here and it is very difficult to breathe without a mask," he said.
"The people in Chaiten are more worried about the lava but here they are worried about how long the situation is going to last.
"We are fine, but we are hoping it will finish.
"Sheep and cows are starting to die because they cannot drink the water, or they are drinking it and it is thick with ash."

Acetate Utilization Test- Principle, Procedure, and Result Interpretation
Objective of Acetate Utilization Test
To differentiate organisms based on the ability to use acetate as the sole source of carbon. Generally used to differentiate Shigella sp. from Escherichia coli.
Principle of Acetate Utilization Test
This test is used to differentiate an organism capable of using acetate as the sole source of carbon. Organisms capable of using sodium acetate grow on the medium, resulting in an alkaline pH, turning the indicator from green to blue.
Media:
 - NaC2H3O2 (2 g/l)
 - MgSO4 (0.1 g/l)
 - NaCl (5 g/l)
 - NH4H2PO4 (1 g/l)
 - agar (20 g/l)
 - bromthymol blue indicator (0.8 g/l)
 - pH 6.7.
Procedure of Acetate Utilization Test
 1. With a straight inoculating needle, inoculate acetate slant lightly from an 18- to 24-hour culture. Do not inoculate from a broth culture, because the growth will be too heavy.
 2. Incubate at 35°-37°C for up to 7 days.
Result Interpretation of Acetate Utilization Test
Positive: Medium becomes alkalinized (blue) as a result of the growth and use of acetate.
Negative: No growth or growth with no indicator change to blue.
Limitations
Some strains of E. coli may use acetate at a very slow rate or not at all, resulting in a false negative reaction in the identification process
Quality Control
Positive: Escherichia coli (ATCC 25922)— growth; blue
Negative: Shigella sonnei (ATCC 25931)— small amount of growth; green

Blow Up is a photo editing tool that keeps the quality of the image after it has been enlarged many times.
A phenomenon that often occurs when you zoom in on an image is that the pixels are far apart, making the image more blurred and out of focus. Blow Up will help you to fix this situation.
Not only can it work as a standalone software, Blow Up It can also be used as an integrated plugin (plugin) into photo editing tools such as Photoshop, Lightroom, etc.

. This should also help compiler performance, by reducing the implicit search space.
 - Syntax is layered in the same way as type classes. Importing the syntax for, say, Applicative will also provide the syntax for Apply and Functor.
Syntax can be imported in two ways. Firstly, the syntax specialized for a particular instance of a type class can be imported directly from the instance itself.
// import the type class instance
import scalaz.std.option.optionInstance
// import the implicit conversions to 'MonadOps[Option, A]', 'BindOps[Option, A]', ...
import optionInstance.monadSyntax._
val oi: Option[Option[Int]] = Some(Some(1))
// Expands to: 'ToBindOps(io).join'
oi.join
Alternatively, the syntax can be imported for a particular type class.
// import the type class instance
import scalaz.std.option.optionInstance
// import the implicit conversions to 'MonadOps[F, A]', 'BindOps[F, A]', ...
import scalaz.syntax.monad._
val oi: Option[Option[Int]] = Some(Some(1))
// Expands to: ToBindOps(io).join
oi.join
For some degree of backwards compatibility with Scalaz 6, the über-import of import scalaz.Scalaz._ will import all implicit conversions that provide syntax (as well as type class instances and other functions). However, we recommend to review usage of this and replace with more focussed imports.
Standalone Type Class Usage
Type classes should be directly usable, without first needing to trigger implicit conversions. This might be desirable to reduce the runtime or cognitive overhead of the pimped types, or to define your own pimped types with a syntax of your choosing.
 - The methods in type classes have been curried to maximize type inference.
 - Derived methods, based on the abstract methods in a type class, are defined in the type class itself.
 - Each type class companion object is fitted with a convenient apply method to obtain an instance of the type class.
 // Equivalent to 'implicitly[Monad[Option]]'
 val O = Monad[Option]
 // 'bind' is defined with two parameter sections, so that the type of 'x' is inferred as 'Int'.
 O.bind(Some(1))(x => Some(x * 2))
 def plus(a: Int, b: Int) = a + b
 // 'Apply#lift2' is a function derived from 'Apply#ap'.
 val plusOpt = O.lift2(plus)
Type Class Instance Dependencies
Type class instances may depend on other instances. In simple cases, this is as straightforward as adding an implicit parameter (or, equivalently, a context bound), to the implicit method.
 implicit def optionMonoid[A: Semigroup]: Monoid[Option[A]] = new Monoid[Option[A]] {
 def append(f1: Option[A], f2: => Option[A]): Option[A] = (f1, f2) match {
 case (Some(a1), Some(a2)) => Some(Semigroup[A].append(a1, a2))
 case (Some(a1), None) => f1
 case (None, Some(a2)) => f2
 case (None, None) => None
 }
 def zero: Option[A] = None
 }
Type class instances for 'transformers', such as OptionT, present a more subtle challenge. OptionT[F, A] is a wrapper for a value of type F[Option[A]]. It allows us to write:
val ot = OptionT(List(Some(1), None))
ot.map((a: Int) => a * 2) // OptionT(List(Some(2), None))
The method OptionT#map requires an implicit parameter of type Functor[F], whereas OptionT#flatMap requires one of type Monad[F]. The capabilities of OptionT increase with those of F. We need to encode this into the type class instances for [a]OptionT[F[A]].
This is done with a hierarchy of type class implementation traits and a corresponding set of prioritized implicit methods.
In case of ambiguous implicits, Scala will favour one defined in a sub-class of the other. This is to avoid ambiguity when in cases like the following:
type OptionTList[A] = OptionT[List[A]]
implicitly[Functor[OptionTList]]
// Candidates:
// 1. OptionT.OptionTFunctor[List](implicitly[Functor[List]])
// 2. OptionT.OptionTMonad[List](implicitly[Functor[List]])
// #2 is defined in a subclass of the enclosing class of #1, so #2 is preferred.
Transformers and Identity
A stronger emphasis has been placed on transformer data structures (aka Monad Transformers). For example State is now a type alias for StateT[Id, A, B].
Id is defined in the scalaz package object as:
type Id[A] = A

text: This work efficiently detects uric acid (UA) in a human blood sample using cobalt nanoparticle-immobilized mixed-valent molybdenum sulfide on the copper substrate in a point-of-care (PoC) device. The sensor electrode was fabricated by micromachining of Cu clad boards employing an engraver to generate a three-electrode system consisting of working electrode (WE), reference electrode (RE), and counter electrode (CE). The WE was subjected to physical vapor deposition of mixed-valent MoSx layers by a reaction between Mo(CO)6 and H2S at ∼200 °C using a simple setup following which CoNPs were electrochemically deposited. The RE and CE were covered with Ag/AgCl and Ag paste, respectively. A plasma separation membrane acted as the medium of UA/blood serum delivery to the electrodes. The material and electrochemical characterization confirmed that CoNPs over MoSx provided an enlarged electroactive surface for the direct electron transfer to achieve an enhanced electrocatalytic response. The binary combination of CoNPs and MoSx layers over the Cu electrode reduced the charge-transfer resistance by two times, enhanced the surface adsorption by more than two times, and yielded a high diffusion coefficient of 3.46 × 10–3 cm2/s. These interfacial effects facilitated the UA oxidation, leading to unprecedented mA range current density for UA sensing for the PoC device. The electrochemical detection tests in the PoC device revealed a sensitivity of 64.7 μA/μM cm–2, which is ∼50 times higher compared to the latest reported value (1.23 μA/μM cm–2), a high limit of detection of 5 nM, and shelf life of 6 months, confirming the synergistic effect-mediated high sensitivity under PoC settings. Interference tests confirmed no intervention of similar analytes. Tests on blood samples demonstrated a recovery percentage close to 100% in human serum UA, signifying the suitability of the nanocomposite-based sensor and the PoC device for clinical sensing applications.

iBird to support monitoring of ecological health in Palau
In Palau, technology in the form of iPods and the iBird application, is helping in the response to the threats of climate change to this Micronesian nation. And it is the local BirdLife partner, Palau Conservation Society (PCS), in association with BirdLife and the Aage V. Jensen Foundation, that is providing these innovative tools.
The role of birds as messengers of the ecological health of the planet is an important part of the BirdLife campaign on climate change. Birds provide key insights into how climate change threatens communities, species and habitats. Nowhere is the threat of climate change better appreciated than in Micronesia in the western Pacific where many of their communities are threatened by rises in the sea level. In Palau, the State Conservation Coordinators are developing a programme to monitor forest health using birds as the indicators.
Last year in November, 11 out of 16 states participated in a week long training on monitoring forest health. During that training, the participants were trained on the different methods in monitoring forest health, including using birds as indicators of forest health. Twelve months on and PCS is able to provide a tool to support monitoring using birds as indicators of ecosystem health.
This November, follow up training on monitoring forest health was held at PCS. This training was a one-hour training on the use of iBird as a tool to support monitoring ecosystem health. Because birds are sensitive to changes in the ecosystem, they are great indicators to stresses in the environment. In order to monitor birds, the conservation personnel must first learn their birds. The iBird Hawaii and Palau application has been chosen as the best way to support this proramme. The app is a guide that can help the conservation personnel to learn their birds so that they will be able to monitor them to assess the health of their protected areas and guide the management efforts in those protected areas.
With funding from the Jensen Foundation, PCS was able to purchase iPods and the iBird app for the participants who attended the first monitoring training and the recent follow up to that training. With the iBird app, conservation practitioners not only have a tool to help them identify and learn the birds in their state protected areas, they are also given a tool that may support future bird watching as a potential ecotourism option.

Trumpf has developed BrightLine Speed, a new technology for cutting sheet metal faster and more efficiently. The solution is aimed in particular at the three-dimensional cutting of hot-formed components, such as those used in the manufacture of B-pillars or door frames in automotive production.
"With BrightLine Speed, we can increase cutting speed by up to 60 percent for sheets up to four millimeters thick," says Ralf Kohllöffel, product manager at Trumpf. Another advantage is that BrightLine Speed reduces cutting gas consumption per component by around half compared to conventional laser cutting. In addition, the cutting process can be 15 percent more productive with the same laser power, which is why correspondingly less energy is required per component. "Our new cutting technology results in noticeable leaps in productivity and cost savings for our customers through more speed and less gas consumption," says Kohllöffel.
Two fibers in one cable
The central component of BrightLine Speed is a Trumpf-patented 2in1 laser light cable (LLK) with an inner and an outer fiber core. A TruDisk disk laser couples laser light into the LLK and distributes the laser power to the inner and outer cores using a so-called wedge switch. This allows the laser's power and beam profile to be flexibly adapted to the sheet thickness to be processed better than would otherwise be possible.

Organic matter and crude protein digestibility predicted from nitrogen and fibre fractionation of festulolium hybrids
|Kateg. publikace||Vědecké publikace impaktované|
The objectives of the experiment were to study nitrogen fractions of the Cornell Net Carbohydrate and Protein System (CNCPS) and digestibility of organic matter (OMD) and crude protein (CPD) along with the possibilities for predicting OMD and CPD based on chemical composition and CNCPS nitrogen fractions. Thirty samples of festulolium hybrids (fescue hybrids and ryegrass hybrids) commonly used and certified in the Czech Republic were analyzed for chemical composition, brutto energy, and nitrogen fractions, these fractions being A (non-protein nitrogen), B1 (rapidly degradable protein), B2 (intermediately degradable protein), B3 (slowly degradable protein), and C (unavailable protein). OMD and CPD were determined by near-infrared reflectance spectroscopy. Nitrogen fractions showed similar mean values for both analyzed groups of festulolium hybrids. Mean rapidly, intermediately, and slowly soluble fractions (B1, B2, and B3, respectively) were 29.2, 30.7, and 33.7 g/kg of dry matter (DM) for fescue hybrids and 21.7, 33.5, and 31.9 g/kg of DM for ryegrass hybrids. There was a trend for fraction B2 to decrease with advancing maturity in relation to neutral detergent insoluble protein value. The mean content of bound fraction C was 10.4 g/kg of DM for fescue hybrids and 7.3 g/kg of DM for ryegrass hybrids. Three groups of hybrids were evaluated statistically: fescue (I), ryegrass (II), and combined fescue/ryegrass (III). Better regression equations were found for fescue/ryegrass hybrids. High degrees of CPD determination were identified with predictors of individual nitrogen fractions (R2 = 0.975; P > 0.0001). OMD was described in regressions only using nitrogen fractions A and B1 (R2 = 0.500; P > 0.0001).

Problem 2: Billet Upset Forging
Consider the isothermal upset forging of the cylindrical billet shown in Figure 2.
Assume that the dies are rigid. Also assume that sticking friction is in effect between the billet and the die faces when they are in contact.

How do I parse an XML, which is stored in a String? Assume the string name is xmlString. It contains 'employee' as root node and firstname, lasename, address as child node.
I tried the following with xml4J parser. 1. Create a parser object Parser p = new Parser("parser.err"); 2. converting a string into an inputstream. ByteArrayInputStream is = new ByteArrayInputStream(xmlString.getBytes());
3. Create the DOM tree TXDocument document = parser.readStream(is); here, document(DOM tree) is null. So, I am not able to get the root element. Why is that??? Thanks

The calculation of radiated acoustic pressure fields from irregular multi-sided polygons
UNSPECIFIED. (2004) The calculation of radiated acoustic pressure fields from irregular multi-sided polygons. JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA, 115 (5 Part 1). pp. 2021-2031. ISSN 0001-4966Full text not available from this repository.

This paper presents a method of calculating the pressure at any point emerging from a plane piston of polygonal shape in an infinite baffle. This is achieved by calculation of the impulse response as a time-stepped function, and considering the effect of each edge of the polygon in turn. The pressure is found from the convolution of this function with the time derivative of the piston velocity multiplied by the density of the propagation medium. Calculated pressure fields are shown for both a series of sources shaped as regular polygons, and for a source with an irregular shape. It is shown that the approach could be useful for the calculation of radiated fields from sources of arbitrary shape. (C) 2004 Acoustical Society of America.

Lattice Energy
From UBC Wiki
Jump to: navigation, search
ChemHelp.png This article is part of the ChemHelp Tutoring Wiki
Lattice energy is the energy required to convert one mole of crystal into its constituent ions in the gas phase at infinite separation. Ionic energy can also be defined to the energy released when a ions form an ionic solid.
M+(g) + X-(g) --> MX(s)
where M is a cation and X is an anion
Two trends when observing lattice energies:
1. The larger the ionic radii of the ions (cation or anion), the farther the electrons are from the nucleus, the easier it is to transfer electrons to form a solid, thus, less energy is required.
This can also be explained by Coloumb's Law
Therefore, lattice energy decreases from right to left and towards the bottom of the periodic table.
2. The divalent ions require a larger lattice energy to form a solid than monovalent ions. This is because twice as much energy is required to remove the second electron from a cation.
