Culinary historians trace the term to the Dutch "sla" for salad.

In 2006, the SLA put up the site for commercial lease.

It is believed he was not active in the SLA.

SLA has been influenced by both linguistic and psychological theories.

SLA did not exist prior to chemical synthesis in 1952.

During those three days 250 rebels were killed according to SLA sources.

He was the last remaining SLA member to face federal prosecution.

In some cases, you may need to accept a supplier's standard SLA.

You must be involved in drawing up the SLA together with the supplier.

However, she refused to give evidence against the other captured SLA members.

A day later, the majority of the SLA positions had collapsed.

In 1994 the SLA withdrew their military bases from this area.

Lyrics: He was born on a summer day, 1951 And with the sla...

However, no SLA members ever used such a weapon.

Young men are informed that they "have to be soldiers with the SLA or we will cut off your town."

In early January, however, the town was taken by the SLA.

By the next day the SLA offensive was broken.

Duncan has also served as managing editor of SLA since 1993.

Every round fired by SLA members at the police missed the officers.

At this time, a number of new members gravitated towards the SLA.

During the school year, SLA operates a clinic four evenings a week.

However there were some instances of bravery on the SLA side.

However, the SLA claimed to have lost only 20 soldiers and killed 27 rebels.

By 2000 the SLA was reduced to 1,500 soldiers, compared to 3,000 ten years earlier.

Soon the government was unable to pay both its civil servants and the SLA.

The second example may have a service level agreement, the first should not.

This can be part of a service level agreement in the contract.

These arrangements are set out in a Service level agreement.

Consider whether a contract or a service level agreement is necessary.

See the page in this guide on service level agreements.

It's important to study the service level agreement and the type of technical support on offer.

Either way, make sure that your service level agreement contains a clear exit strategy.

How good are the service level agreements it offers?

It is possible to establish service level agreements at the use case level.

The service level agreement forms part of the contract between you and your outsourcing partner.

This includes understanding the volumes of data that will have to be processed within service level agreements.

Buy insurance and agree service level agreements with the insurance company.

Make sure that any contract you sign with an agency includes enforceable service level agreements.

The commercial relationships are underpinned with service level agreements which guarantee performance, quality and security.

Westminster has 17 service level agreements with voluntary organisations and all report an increase in activity.

This type of disclosure is typically guaranteed as part of a service level agreement.

Many dedicated server providers include a service level agreement based on network uptime.

Service level agreements are also defined at different levels:

Industry sources said that complex service level agreements with corporate customers were slowing the decision-making process.

Negotiate guaranteed delivery times with the carrier you have chosen or set service level agreements that they must meet.

Consider drawing up a contract or service level agreement to ensure that you receive good service from them.

Service management is implemented for all critical services with service level agreements and operational reviews.

This same approach is used in the service industry where parameters are replaced by processes related to service level agreements.

In particular, users appreciate predictability - servers that always meet or exceed service level agreements.

The proliferation of service level agreements.

VRLA batteries offer several advantages compared with flooded lead-acid cells.

VRLA batteries immobilize the electrolyte, usually by one of two means:

The cell walls of VRLA batteries typically swell when the internal pressure rises.

Gel VRLA batteries are best for this purpose.

VRLA batteries are commonly further classified as:

VRLA batteries are used extensively in power wheelchairs, as the extremely low gas and acid output makes them much safer for indoor use.

VRLA batteries:

Since VRLA batteries do not require (and make impossible) regular checking of the electrolyte level, they have been called maintenance free batteries.

Wet cells have open vents to release any gas produced, and VRLA batteries rely on valves fitted to each cell.

For higher-powered lights, an external battery pack of 12V VRLA battery is often required.

Constant-voltage charging is the usual, most efficient and fastest charging method for VRLA batteries, although other methods can be used.

This sealed, non-spill feature made it possible to make very small VRLA batteries (1 -12 Amp hr.

The VRLA battery uses an immobilized sulfuric acid electrolyte, reducing the chance of leakage and extending shelf life.

VRLA batteries are also used in the UPS (uninterruptible power supply) as a back up when the electrical power goes off.

Because of their construction, VRLA batteries do not require regular addition of water to the cells, and vent less gas than flooded lead-acid batteries.

The electrical characteristics of VRLA batteries differ somewhat from wet-cell lead-acid batteries, requiring caution in charging and discharging.

The sealed valve regulated lead-acid battery (VRLA battery), popular in the automotive industry as a replacement for the lead-acid wet cell.

A VRLA battery (valve-regulated lead-acid battery) more commonly known as a sealed battery is a lead-acid rechargeable battery.

Because AGM VRLA batteries use much less electrolyte (battery acid) than traditional lead-acid batteries, they are sometimes called an "acid-starved" design.

GR-4228, VRLA Battery String Certification Levels Based on Requirements for Safety and Performance, is a new industry-approved set of VRLA requirements that provides a three-level compliance system.

A gel battery (also known as a "gel cell") is a VRLA battery with a gelified electrolyte; the sulfuric acid is mixed with silica fume, which makes the resulting mass gel-like and immobile.

VRLA batteries are used in the outside plant at locations such as Controlled Environmental Vaults (CEVs), Electronic Equipment Enclosures (EEEs), and huts, and in uncontrolled structures such as cabinets.

As long as the ripple current is not excessive (more than 3 to 4 times the battery-manufacturer-recommended level), the expected life of a ripple-charged VRLA battery is within 3% of the life of a constant DC-charged battery.

Apart from the conventional Flooded Flat Plate batteries for Automotive application, Exide also produces industrial range of batteries, which includes, Flooded - Flat plate, Flooded - Tubular plate, Flooded - Plante and Sealed Maintenance Free VRLA batteries.

The compliance system provides a common framework for evaluating and qualifying various valve-regulated lead-acid battery technologies.

A valve-regulated lead-acid battery (VRLA) is a battery type that is popular in telecommunications network environments as a reliable backup power source.

A VRLA battery (valve-regulated lead-acid battery) more commonly known as a sealed battery is a lead-acid rechargeable battery.

Other electric systems include 12 volt lighting with valve-regulated lead-acid batteries since they can also provide power for air compressors that fit in automotive cigar lighter receptacles when tires go flat.

The company Accumulatorenfabrik Sonnenschein had been founded in Berlin in 1910 by Theodor Sonnenschein, and had patented the gel-cell type of valve-regulated lead-acid battery in 1957.

Other advantages it offers is the potential ability to power a PC off a sealed lead-acid 12 volt battery, or from automotive power without using a power inverter.

Valve-regulated lead-acid (VRLA) batteries, usually known as sealed lead-acid, Gel, or AGM batteries, minimize the risk of spillage, and gases are only vented when the batteries are overcharged.

To keep the Gel Cell at full charge, if I miss a couple weekends."

Initially, standard flooded golf cart batteries were used, replaced in later models by Sonnenshein gel cells.

The system was powered by a gel cell battery that lasted for twelve hours, which enabled Fricke to shoot without the use of a generator.

A gel cell has the electrolyte mixed with silica dust to form an immobilized gel.

But for wedding photographers and paparazzi used to lugging around heavy high-voltage batteries, these modern "gel cells" are a blessed relief.

Gel batteries (or "gel cell") use a semi-solid electrolyte.

These batteries are deep cycle sealed GEL cell batteries that are non-hazardous and fully recyclable.

Gel battery ("gel cell") An absorbed glass mat battery has the electrolyte absorbed in a fiber-glass mat separator.

Non-Automotive Lead-Based Batteries Gel cells and sealed lead-acid batteries are commonly used to power industrial equipment, emergency lighting, and alarm systems.

A sealed lead acid battery or gel cell is a lead acid battery that has the sulfuric acid electrolyte coagulated (thickened) so it cannot spill out.

The absorbed glass mat (AGM) type uses a glass mat separator, and a "gel cell" uses fine powder to absorb and immobilize the sulfuric acid electrolyte.

Wet cells are still used in automobile batteries and in industry for standby power for switchgear, telecommunication or large uninterruptible power supplies, but in many places batteries with gel cells have been used instead.

A gel battery (also known as a "gel cell") is a VRLA battery with a gelified electrolyte; the sulfuric acid is mixed with silica fume, which makes the resulting mass gel-like and immobile.

The basic principle has not changed since 1859, though in the 1970s a variant was developed that used a gel electrolyte instead of a liquid (commonly known as a "gel cell"), allowing the battery to be used in different positions without failure or leakage.
