announces its results for the second quarter 2014

Schlumberger Limited (NYSE: SLB) today declared a turnover of 12.05 billion for the second quarter 2014 compared to 11.24 billion USD in the first quarter of 2014, and 11.18 billion USD in the second quarter of 2013. The turnover for the second quarter climbed 7% sequential and increased by 8% year on year, the turnover of the area international recording an increase of 604 million USD to $ 8.09 billion USD, or 8% in sequence, while the turnover of the North America zone increased by 205 million USD to 3.89 billion USD, 6% sequential.

The gain from continuing operations attributable to Schlumberger, excluding charges and credits, amounted to 1.80 billion USD, an increase of 13% sequential and 17% YOY. From earnings per diluted share from continuing operations, excluding charges and credits, amounted to 1.37 against 1.21 USD in the previous quarter, and 1.15 USD in the second quarter of 2013.

Earnings from operations before income taxes for the second quarter reached 2.62 billion USD, an increase of 11% sequential and 15% YOY. Earnings from operations before income taxes for the International of 1.94 billion USD has increased 14% sequential, while operating income before taxes of 700 million USD in North America increased 3% sequential.

The second quarter pre-tax operating margin amounted to 21.7%, reflecting additional operating margins of 39% YOY. Earnings from operations before income taxes for the International amounted to 24.0% while the operating margin before taxes in North America amounted to 18.0%.

Paal Kibsgaard, president and CEO of Schlumberger, said in these terms: "the solid results of Schlumberger in the second quarter are stimulated by a significant increase in activities in the offshore time and markets key terrestrial. The growth has been the strongest international with the rebound of activities in a number of areas, but she was significantly greater in North America with a strong offshore activity and extremely substantial progress in the land area despite the debacle of the spring in the Canada. All areas and all groups have recorded growth supported by the robustness of our performance and the penetration of our new technology.

Geographic results were conducted by region Europe/CIS/Africa, Russia having recovered well effects of a harsh winter and the Norway benefited from an active seismic summer early. In the Middle East and Asia, the growth in the key markets of Saudi Arabia and of the Australia has been amplified by seismic activity and drilling geographical market * of the United Arab Emirates, and by the growth of the seismic operations in the Qatar. In North America, in double digit growth recorded in the terrestrial part of the United States in response to the increased number of the rigs, to gains in efficiency and improved market share has more than offset the effects of which proved be a spring meltdown fast to Canada, while the offshore work in the U.S. Gulf of the Mexico portion has bounced back with the resumption of drilling on oil platforms. Latin America has benefited from strong growth in Argentina, Colombia and the Venezuela but overall results have suffered the impact of activity reduced to Mexico, while the turnover of the geographic market of the Brazil remained unchanged in sequential.

Growth fueled by the technology was the highest for the products and services of the Group characterization of reservoirs with an increased demand for cable services due to the rebound of the activity of drilling in Russia and Norway, while the seismic activity has increased in the North Sea and the Middle East. The Group of drilling, M - I SWACO has found strong international activity in Russia, sub-Saharan Africa and Latin America. Drilling & measurements showed an improvement due to an increase in drilling in North America and Russia. Technologies of the Production Group increased in response to increased use of the pumping by pressing the share of the sector in the terrestrial part of the United States and the expansion of international sales Completions. New technologies sales remained strong through the groups and have achieved an increase in the price although price levels remained competitive as a whole.

Global economic conditions remain mixed as a whole, the recovery from the effects of an unusually cold winter in the United States, coupled with a previ.

Europeans. Italy-Spain 8-12 in the quarter, azure

The Italy suffers, try a memorable comeback, but succumbs to the Spain game 12-8 (4-1, 4-2, 3-3, 1-2) and the primacy of the Group B that would have gotten while losing by two goals.
In the quarter-finals of the 15th edition of the women's water polo Championships, taking place at Alfred Hajos swimming in Budapest, the CONI profile champion will face Greece, third in Group A won from Holland that awaits the winner in the semifinals. The tank will return Tuesday at 18.
The first quarterfinal instead will be among Hungary hostess and Russia, which will play the semi-finals with world champions Spain and Olympic champions.
The azzurre, below even 3 and 9-10-4, trying to reduce liabilities reaching the -3 with 3 ' 45 to play and two consecutive scores of Jerry, author of four goals, but then fail to exploit the latest numerical superiority (5/11) that would guarantee qualification to the medal zone, undergoing the next action -4 to 45 seconds from the end and with the man (5/10), from best scorer Tarrago Aymerich, of the match with five goals. To sign for the CONI profile even Radicchio (2), Garibotti and Captain Of Mario.
For statistics is the first time that Italy loses to Spain at the European Championships.

The Chronicle. The Spain attacks the water moves faster and leaves no blue references covering with spaces. Jerry-served by Fernandez, evading three defenders intervention-Lopez's goal equalised Sucker; then Spain becomes the only numerical superiority conquered with Garcia and passes twice more from the perimeter with diagonals photocopy of Pareja and Tarrago for 4-1. Meanwhile Italy fails three numerical superiority.
In the second time Spain continues to weave its plot of fast and precise steps and, above all, to not fail L'UOMO in più, reaching the +5 (8-3). Garibotti with a conclusion from afar responds to Lopez Sucker marks in numerical superiority; By Mario transforms the penalty won by Fernandez in response to shooting a sketch of Tarrago Aymerich, who then hits twice in numerical superiority (4/0/3 4 against).
The third time does not change the balance and passive, but at least the Italy you unlock in numerical superiority by transforming with Jerry and Radicchio twice three times out of four. Spain marks the only men with Garcia (9-3), Espar Llaquet (10-4, full advantage) and Miranda Dorado for 11-6.
The passive would condemn the CONI profile in third place and a treacherous quarter-final with Hungary landlady; need to reduce the gap and try until the end to reach the top spot on goal difference. Jerry becomes two numerical superiority, while the defense will save three with Gorlero highlights (11-8). The azzurre are a goal from semifinals, but fail the eleventh numerical superiority (5/11), while best scorer Tarrago-Aymerich of the match with 5 goals-closes the games to 45 seconds from the end (5/10). Remains bitter taste in mouth for a start too late and return contract. Tuesday at 18 there is Greece in the quarterfinals. The winner will face in the semifinals the Netherlands who won the Group A.

The surfaces of all the solid things in the solar system, put together

Randall Monroe, former NASA consultant and the author of 2005 's hugely popular "comic site xkcd" "on romance, sarcasm, math and language ', has created an interesting illustration to get an idea of how our solar system would look if you combined all surfaces of its solid bodies.

 In the middle of the map there is the Earth's surface, recognizable from the continents and oceans that are around them, with a total extension of about 510 million square kilometers that makes us the largest Rocky planet in the solar system. Follow, as far as the planets, Venus, Mars and mercury.

 Of course every territory on the map is made in proportion to the size of the Earth and in the list in addition to the planets include moons, asteroids and other small bodies. In short, only with the land deal with a lot of space, but a space probably infinite.

A huge challenge

Facing the question, Fred Bachelier demonstrated the utmost caution. Failures of the pauloise in the final and the Saint-Louis in the first round of the competition, without forgetting the defeat at the games of the Seychelles Islands, are still present in our memories. Réunion football no longer dominates the area. "Probably because we attach not the same importance to these confrontations", underlines the technician of the Sainte-Sagar. The cup of champions in the Indian ocean Solid surface, which plays almost in total indifference on our island, is the perfect example. As where two years ago, our champion quickly measured the fervour that reigns at Majunga, home to the first act of the finale of this fourth edition. "Since we arrived, everyone talks about this event", said Bachelor. "There are constantly on television commercials. The national channel will rebroadcast the live match where not less than 13,000 tickets have already been sold, resumes Vice President Thierry Cortez. For them, it is a big party that must ruin". We understand the reason why Madagascar reigns on the competition of the UFFOI for three years.

Heat, synthetic, solidity and technical

2011 finalist and winner in 2012, Cnaps Sports has put the package to prepare this deadline. "She arrived long before we at Majunga." For her, the issue is size. She does not want to disappoint his audience", notes Saint-marien coach who could yesterday morning, see his opponent at work. "He has trained just after us." There was no implementation, but have been noticing that there were sacred templates in front." This justifies its reputation of strong team, in the image of its coach Hery Be, former advocate of mythical FC BFV. "And like all teams of the big island, she is at ease technically. With big heat prevailing, our task is to size."

St. Marians will play this afternoon at 14:30 (3: 30 p.m. hour meeting) at a temperature above 30 degrees. And on the synthetic surface that has never managed to pei soccer in recent years. The pauloise in the CCCOI and Coupe de France Lannion, or even the selection of the 2011 JIØÍ meeting may recall. "It's complicated but our goal has not changed, reframes Thierry Cortez. Since our arrival, it adapts to the conditions. The goal is to not lose energy unnecessarily." Because this final will not be completed at the start of the big island. "We must be in place to effectively manage this game on the defensive plan. After, if one has the ability to be very effective for, knowing that we should not have many offensive situations, it would be nice for the return." Saint-Marien intends to thwart the plans of "Cashiers" who hope to go on 3 August at the stage of the East with a safe margin. "It is a final, there is a trophy at the end. We also, we are determined", launches Bachelor, eager to put an end to the Malagasy supremacy. Hoping that the trio of Comorian arbitrators who will lead this final go, will not do as much misery as his 2012 compatriots who had completely wiped out the chances of success of the pauloise in Majunga. The inter-island confrontations, it is also.http://www.furnituresolidsurface.com/

Analysis of Surface Energy of Solids

Contact angle is the angle where a liquid or vapor interface meets a solid surface and is generally used as the most direct measure of wetting. The main focus of contact angle studies is to measure the wetting characteristics of a specific liquid on the solid substrate. The contact angle θ is a virtue of the relative surface energies of the liquid vapor, solid-liquid (SL), and solid vapor (SV), as illustrated in Figure 1. This article elucidates the analysis of surface energy of solid substrates using the force-rebalance method or the sessile drop technique.

Figure 1. Contact angle as a function of the three surface energies.
Contact Angle

Young gave the mathematical expression of this relationship as

γSV = γSL + γLVCOSθ

In some samples where the solid substrate has a surface energy much higher than the liquid, cosθ approaches 1 as the contact angle approaching 0, denoting that the liquid spreads on the substrate’s surface. When the solid has a much lower surface energy than the liquid, cosθ approaches -1 as the contact angle approaches 180° and the liquid is nearly completely non-wetting, as shown in Figure 2.

Figure 2. Contact angle of poorly wetting liquid (left) and well wetting liquid (right). Assuming the same liquid, the substrate on the left has a much lower surface energy than the substrate on the left.
Experimental Parameters

Other experimental parameters can be obtained directly from surface tension and contact angle results. Some examples are as follows:
Work of Adhesion

It is defined as the work needed to isolate the liquid and solid phases, or the negative free energy related to the adhesion of the liquid and solid phases. Work of Adhesion is utilized to express the strength of the interaction between the liquid and solid phases. It is given by the Young-Dupre equation as:

Wa =γ (1 + COSθ)
Work of Cohesion

It is defined as the work needed to isolate a liquid into two parts, and is a measure of the strength of molecular interactions within the liquid. It is given as:

Wc = 2γ
Work of Spreading

Work of Spreading, also called as Spreading Coefficient, is the negative free energy related to spreading of liquid over solid surface. It is given as:

Ws = γ (COSθ - 1)
Wetting Tension

It is a measurement of force/length and is defined as:

τ = Fw/p = γLVCOSθ

This value also denotes the product of the cosine of the surface tension and the contact angle. It enables the characterization of the strength of the wetting interaction sans separate measurement of surface tension. This latter equation can be utilized in a separate approach to measure the contact angle by means of the strength of interaction between the substrate and the wetted meniscus. In this configuration, a flat plate is immersed into a liquid and the ensuing meniscus produces the force Fw, enabling extraction of the contact angle (Figure 3).

θ = atan(-ET/2)

Figure 3. Schematic of forces arising from wetted interface in a flat plate configuration.
Direct Optical Measurement of Contact Angle

The most optimal approach for ascertaining contact angle is direct optical measurement of the contact angle using a high resolution camera or microscope. While the contact angle can be determined directly, it is often measured geometrically using the observed diameter and height of the drop on the surface (Figure 4). This method not only eliminates uncertainties regarding the precise angle at the interface, but also results in an average contact angle and does not handle receding and advancing contact angles quite well.

Figure 4. Representative image of a sessile drop with construction lines shown.

A different approach can also be used by applying techniques which are not defined in ASTM standards. This approach utilizes direct measurement of the wetting force and hence enables simple measurement of receding and advancing contact angles and is inherently not at equilibrium. It is often called as "Dynamic Contact Angle". In this technique, forces that are directly measured are utilized to calculate contact angle. First, the liquid’s surface tension must be determined. A de Nouy ring, which is a thin platinum wire of perimeter ρ, must determine the surface tension (Figure 5). The force needed to pull the ring clear of the water is directly related to the surface tension through:

γL = Fmax / ρ

Figure 5. Image of a de Noüy ring at point where meniscus is stretched to almost breaking point.

After the surface tension is known, an experiment can be conducted where a known geometry is impeded into the liquid and the ensuing wetting force generates the contact angle from the equation above. This method enables simple measurement of receding and advancing contact angles when the surface is dry and already wetted. The equipment can also be utilized to ascertain other wetting phenomena such as wicking.

In order to distinguish the wetting behavior of a specific solid/liquid pair, it is important to quantify and report the contact angle.surface energy, it is essential to employ a range of liquids of known surface energy. Tiny drops are placed on the substrate’s surface, and the contact angle is determined optically, as illustrated in ASTM D5946.

The calculations based on these measurements create a parameter with the units of force/unit length. The two common techniques used to determine this parameter are critical surface tension and free surface energy.

Figure 6. Critical surface energy for polyethylene determined from the Zisman plot.

A technique was developed by Zisman to estimate the surface energy of solid substrates. Using a range of homologous liquids of varying surface tensions, the contact angle θ is measured for each liquid. Based on these measurements, a graph of cosθ 8 vs γLV is drawn, where γ represents the liquids’ surface energy. The line is extrapolated to cosθ = 1; the value of the surface energy where the line crosses 1 is called the critical surface tension, and indicates the maximum surface tension of a liquid that may completely wet the substrate (Figure 6).
Free Surface Energy

Another approach to differentiate a solid surface is by measuring free surface energy, also called as solid surface tension. In this method, the solid is tested against a range of wetting liquids that are well characterized. The liquids utilized must be characterized in such a way that the dispersive and polar components of their surface tensions are known. The related equation is given by Owens and Wendt as:

γ1 (1+ cos θ) / (γld)1/2 = (γsp)1/2 [(γlp)1/2 /(γld)1/2] + (γsd)1/2

where θ represents the contact angle, γ 1 is liquid surface tension and γ s is the solid surface tension. The addition of d and p refer to the dispersive and polar components of each. The relationship of (γld)1/2 /(γld)1/2 vs Y I (1+ cos θ ) / (γld)1/2 can be plotted; the slope will be (γsp)1/2 and the γ-intercept will be (γsd)1/2. The overall free surface energy is just the sum of its two component forces.

This article described the analysis of surface energy of solid substrates using either the force-rebalance method or the sessile drop technique. These methods give compatible values, but offer different tools for assessing the materials’ surface properties.

Solid surface Availability

Solid surface is available in hundreds of colors and visual textures, ranging from solid colors to marbleized, granite effect or wood grain. Cultured marble, cultured granite, and cultured onyx describe solid surfaces colored to resemble natural stone. Dozens of multinational companies manufacture solid surface sheet goods and sinks for the world market; and hundreds of smaller, regional manufacturers produce for local markets.

Although Solid surface sheet competition from natural stone and engineered stone/quartz surfacing, the material is popular in Asia, particularly in residential new construction. An emerging market for solid surface is in commercial and industrial settings, where its non-porous characteristics, combined with durability, renew-ability and form-ability make it the material of choice for many designers and architects. Also appealing, is the wide range of colors and textures, as well as the ability to custom-color the material for large projects. Hospitals, in particular, employ large amounts of solid surface for sinks, showers, nursing stations and wall cladding, because its seamless properties eliminate gaps and crevices that harbor harmful bacteria.http://www.furnituresolidsurface.com/
