There is no way to claim on Jane


seems incredible that one of the leading companies dedicated to products Children and babies tnega no clear way to contact them, complain or make suggestions.

The Jane website there is not a single email to that contact. Diving for internet indicating some who see the address is indicated info@jane.es to contact them.

Therefore, 3 weeks ago I am writing to ask you a question related to an article that has been withdrawn for safety reasons, however, despite the time trasncurrido and the importance of the topic, I get no response from this company .

bad I think the opacity of this company.

Low-power lifts

The elevators
are one of the present electricity consumption in buildings. Its consumption largely depends on the following factors :
  • Main use of building: residential, hospital, administrative ... Features
  • of building height, number of units in use ... Type
  • elevator technology.

The use of the building affects according to frequency of use of lifts by users. For example, in a hospital where there occur inpatients increased traffic of users in buildings with other uses.

is important to make an estimate of the frequency of use of the elevators in the building at the time of making a correct estimate of their energy .

On the other hand the edifcio characteristics also significantly affect their consumption and high-rise buildings will be more significant consumption as a smaller number of users used the stairs and the consumption path will be higher.

In terms of technology distinguish the following types Elevator: Hydraulic lifts
  • .
  • two-speed electric elevators. Electric Lifts
  • variable frequency and voltage. Electric Lifts
  • variable frequency and voltage without engranajescon permanent magnet motor and heavy-duty flat ribbons, ie art lifts and high energy efficiency.
This latter type of lifts are an important technological change in regard to low power consumption and energy efficiency:
  • consume between 25% and 40% less than conventional electric lifts.
  • Consume 60% less than hydraulic lifts.
  • are very quiet.

The following table takes compratir consumption a lift last generation and an electric elevator conventional two speeds depending on the capacity of the same:


deserve consideration all these factors when making a correct choice of lift to be used in a building.

district heating (district heating)

The district heating systems are based on the principle centralized production of heat (or cold) is more efficient than production distributed across the points of consumption. So

thermal generation power plants made in that serve entire communities, whose size can range from a group of building neighborhoods and entire villages.

The performance of these systems is estimated to be 10% higher than centralized systems for building and 30-40% higher than the individual systems.


These thermal very different technologies can be used as are
  • Conventional boilers based on combustion of fossil fuels or biomass . Central
  • of cogeneration generating electricity and heat together using the energy surplus electricity generation process.
  • solar thermal power plants that use solar energy.
  • that use geothermal energy field.
heat (or cold) generated is distributed to points of consumption through a network of distribution pipes usually buried and insulated to prevent heat loss, there are also systems with open pipes. There is a circuit and a return trip.

distribution pipes
The piping material is usually copper, stainless steel or carbon steel, while the heat transfer fluid is usually water liquid or vapor.

In buildings heat applicants must provide a set of thermal substations in which they performed intercabio heat between the heat transfer fluid or primary and fluid transfer to the terminal points of consumption. These substations are also responsible for the accounting of energy consumed.

One of the best known is the steam system of the City of New York, currently operated by Consolidated Edison and carrying steam to heat or cool environments to more than 1 million customers.
In Spain there are several examples of district heating, particularly in Madrid, Esperanza Colony (about 3200 apartments of 110 m² on average), Barrio Altamira Orcasitas Plateau. It also highlights the power station of the campus, designed by architect Manuel Sánchez Arcas and engineer Eduardo Torroja, who was the National Architecture Prize in 1932. This plant serves many faculties of the University Complutense of Madrid.

My Hair Is Thinning In The Front, Help

About complaint forms


In addition to my article "How complete a claim form? " below summarize issues related to this issue.

What are the complaint forms?
are a tool with which the consumer or user account to deliver to the Administration a complaint about a product or service that does not meet the established requirements.

establishment Do all have the obligation to take?
Yes, although there are exceptions. So there are cases that have their own regulations are not obliged to be complaint forms. In any case, the consumer may file a written complaint with the Department of Consumer Affairs, Consumer any Municipal Office or go to a consumer association.

Does the establishment is obliged to announce that it has complaint forms?
Yes, through a sign posted in a conspicuous place.

How do I fill the complaint forms?
should be completed in the same establishment, with a capital letter, and save any document, invoice, warranty, brochure, ticket ,...- proving the service or the purchase of the product. In the Consumer complaint form should fill out your name, your ID card number and the reason for your complaint as clearly as possible. There is a space reserved for the head of establishment to record their version of what happened. The leaves should also include details of the establishment and must be numbered.

Which agency oversees them?
The autonomous communities are responsible for safeguarding the interests of consumers. The complaint forms should bear the letterhead of the Department of Consumer Affairs of the relevant community. The complaint forms consist of three copies. The consumer must keep two copies: the white green. The pink copy will remain on the premises. The white must be submitted before the expiry of one month, the Administration, Department of Consumer Affairs where conflict has occurred, and the second is the consumer keeps the document that certifies that it has submitted the claim. The user can also submit any document that serves to substantiate the complaint. If done by mail is preferred to be certified, or even better burofax, for the record that has been sent. It is recommended that the USER enter the file number to be able to monitor it subsequently.

What if an establishment does not want to give me the complaint forms or not have?
In this case the establishment would violate the law and the client can report the case to any Office Municipal Consumer Information Office (OMIC) or call the Municipal Police and to report the incident. Fines can range from 3,000 to 12,000 euros.

How to solve the conflict?
Once the Administration handled the complaint, the first step is mediation, the administration gives 15 days for establishing a settlement. If no agreement can go to court or arbitration of consumption that is coluntario-for both parties, and free. The arbitration panel heard the parties and issues a written ruling is binding. In the case of non-compliance, a complaint may be filed in a Court of First Instance.

What is the role of consumer associations?
Consumer associations and provide information to users who wish to report a violation committed by a trade. Even handled the complaint forms. If necessary go to court, consumer associations are in charge of the formalities to be satisfied to take forward the cause. Also enjoy the benefit of legal aid, so the costs of judicial procedure abarantan enough.

thermal insulation exterior walls with polyurethane

Proper insulation
of the exterior walls of buildings is one of the factors affecting more important energy demand of them. The materials

insulation commonly used in building construction highlights of rigid foam polyurethane.

This material is produced in situ in the work as a result of the combination of two liquid components at room temperature, the polyol and isocyanate . The union of the two components creates an exothermic chemical reaction following the formation of bonds between both components. The product has a cellular structure and rigid consistency. is called rigid polyurethane foam PUR or .

microscopic view closed-cell PUR

Features include:
  • Low density of about 35 kg/m3 due to its lattice structure with a large amount of air inside.
  • Low thermal conductivity, the order of 0,028 W / (m K).
  • Waterproof.
  • allows the diffusion of water vapor.
Because of these characteristics is a material used in applications that seek to reduce the flow of heat through walls, whether indoors or outdoors.

There are two modes of manufacture / application work:
  • Implementation by projection, spraying the two components simultaneously on the surface that serves as sutrato.
  • Implementation by injection or casting both components are mixed by churning and placed in a cavity where there is expansion.
These application techniques coupled with excellent adhesion properties on almost any substrate make your application be comfortable and fast, promoting continuity and absence of joints that could diminish their effectiveness.

material is resistant to aging due to their microscopic structure that impedes the inside of water or dirt that might degrade it.


There are many constructive solutions for roofs, facades and interior walls that apply PUR either phase of construction and rehabilitation of buildings. In future posts

develop some of these solutions that reduce energy demand of buildings and CO2 emissions to the atmosphere.

continuous calls the number 1004: Movistar


several days I've been getting calls from 1004. A few days ago I was called at 21:30 for two days to call today about 12:00 and I finally caught when they called me at 9:20 in the morning.

I was working but it is December 7, a typical day the bridge and call in advertising with calls at that hour of the morning it seems totally inappropriate. Of course winter call at 21:30 of the night is not very logical.

Ultimately that to stop bothering him are lame and Movistar. A man with an accent of America I want to offer services Movistar.

Another number that I put on the agenda of associating Spam Mobile silence as a ringtone.

only a month ago operators signed a code of conduct to regulate their telesales operations, in order to try to be as less intrusive as possible in the sales calls. The code leaves much scope for hours and still be annoying.

In fact should not be allowed to receive unsolicited commercial calls, but interests and pressures that lead operators need not be approved Act.

Mediamarkt: Another scam (Delicom SL)

This morning when I enter my hotmail mail I find a side banner appears the Mediamarkt that is:


By now we all know that there is something behind all this and that will not give you anything but I was curious to see how this works. If you click on any of the cards (no matter what) you see this another banner:

Okay, I have touch 3000 euros, what luck!
Now I have only to pick up my prize. If I click on "Pick up your card 'shows:


After telling me that I have had a gift card and pressing a button I can pick up the card, it turns out that it was a subscription to a service delivery message to the "small fee" of 1.42 euros per message and 25 messages per month (35.5 per month by entering a drawing course.)

At least in the small print (the fine print is the most important and that we must first read always) Delicom identified as SL and show how to unsubscribe of these bloody message is sending a message down to 797759.

Why I say this is a scam, if the fine print shows it? Because few people know who are actually hiring a subscription service, they think they are sending a gift certificate or that they will be included in a draw, but are unaware that they are going to do is get a lot of messages exorbitant prices indefinitely.

IPad in La Caixa: No matter Avoid calls



This afternoon, he entered the La Caixa's electronic banking, I see a promotion for which you provide in a IPad Caixa exchange for entering into a term deposit.


Well, I say, because who knows if it's interesting. Although never far gifts offered by banks and customers interested in anything at all. I think it is always a real scam.

Let's see here. The conditions are:

words, we offer a 16 GB 3G Ipad for a fixed period from 18,000 to 18 months.
Consider what interest rate the market offers term deposits. On this date (November 2010) is not difficult to find time deposits to 4% for similar periods. Let

calculation: 18.000 * 4% * 1.5 = 1,080 euros (multiplied by 1.5 and 18 months is one and a half).

words, we "sell" the IPAD by 1,080 euros.

And how it's currently 16 GB 3G iPad? For

internet tracking a minute give me a store that offers a 629 euros (and surely you can find cheaper).


So I am losing 451 euros for using the promotion of La Caixa.

So again this promotion does not matter at all to customers. Worth more to a fixed term normal (get paid with money and not with gifts) and buy the iPad.

While the gift you give it to hire the imposition supposed to pay 451 euros a premium of 71% of the value of "gifts."

Everyone can draw their own conclusions.

1444 (and other spam)

not stop now call an acquaintance of the number 1444. When you take anything escuha not reject the call and when called again shortly afterwards.




As I read more Vodafone phone spam.


I remember a way to stop bother us:
  1. tlf Believe in your group, call it eg "heavy"
  2. Add the 1444 to the agenda. Assigns
  3. 1444 the group "heavy"
  4. Change the tone of the group "weighs" a silent and without vibration.
Ideally, these phones have an option to have a blacklist and reject calls directly from numbers that indicate, and I think there is any software out there that allows some phones, but it is not them interested companies at a disadvantage mobile operators.

What Is A Normal Period?

Robbery at the box office supermarkets with alleged scams


Today I received the following letter, which I aconsjeable Share:

not leave anything you can think of at the box office there at the entrances to Eroski, Carrefour, Mercadona Consum etc.

There are several "artists" who are dedicated to putting a coin in the locker, close it and take the key.

So far nothing unusual, but ... What are the key??

Make a copy back again to the box office, leaving the original in the lock to get his money and waited. When someone deposits other store bags or anything else bearing the same ticket and get into the shopping center and you imagine what happens next ...

The "artist" box office opens quietly with your copy of the key and takes what you have inside. Easier and cheaper .... IMPOSSIBLE!

very careful, that being an easy practice to do so in any public office window!

What Are Synonyms Of Lyme

bills outstanding books



This came a few years ago in a company where I worked, and then me exactly what happened in another same.


Call a lady (in this case were numbers of Barcelona) with security, when he had an outstanding bill from a book. The book always has a name quite "official." In our case it was "Trade Directory" or "Report expoter" or something similar. In both cases called a distribution company. The woman I confirmed all invoice data (name, address, zip code, all that we can find in the yellow pages and in the end I asked the account number on the invoice).


That's when you say, but who has asked for that book and I said the manager or person responsible for administration. In both cases he knew that was impossible because being a small company we knew there had been no such request. If I said I had insisted the order signed and faxed to you. The fax never came.


On one occasion they called (possibly more than one person involved in this) a friend gave him the account number.


A few days later I get a charge to the account of about 80 - 90 euros (on behalf of such Susana Castaño) that logically returned. Never did any book, nor would arrive.


To what is this scam?


suppose to take a list of companies and called them all. Many sting, especially those organized or larger worse or decentralized. Then make a charge in mind that if companies realize they earn it. Possibly even if not returned the money they send you a folletillo that no one has asked for a respectable sum of money.

Given the low cost that has to call companies and how easy it is to bite the companies I guess it's quite profitable. After addition would be very easy to say that they had asked the telephone book, which has the back cover.


So much eye to strangers who ask for your account number and above all we must continually review the bank statement to see that no improper charges.

Kitten Conjunctivitis

Commercial Chemical Regent edge


Today has been one thing that usually gives me really angry. Called a commercial for a company (in this case such a Regent Patricia Chemical, a cleaning company of Barcelona) asking directly by the Manager to arrange an appointment.

So much good, since it is their job, but what are the ways objectionable, many impositions, you first name terms with a certain arrogance, and when questioned that he made to screen calls and data does not give you only want to talk with manager. You want an appointment, you want an appointment, and when you say you have to discuss with you the details of your appointment because the manager does not address these calls you will loose a profanity and hangs up.

I think the image of a company can be badly tarnished with such commercial.

high efficiency lighting, LED technology

In recent times the use of lights with LED technology is becoming widely available because of growing concerns about the savings and energy efficiency lighting facilities.

This type of lights are already used in a wide range of applications such as:

- Panels informative.
- Signals.
- low-energy lighting.

Its operation is based on the use of a special type called LED semiconductor diode (the acronym of Light Emitting Diode).

This type of light-emitting diodes spectrum reduced to be polarized by a circular supply voltage and an electric current through them. This effect is known by the name of photoluminescence.

The main advantages of LED-type lights are:

- High luminous efficiency, ie the number of lumens provided for every W of electricity consumed. So luminous efficiency is about 80 lumens / W compared to 55 lumens / W in the so-called energy saving light bulbs and 10 lumens / W for conventional bulbs.
- Low temperature: the low consumption of LED heat production thereof is low.
- Quick Reply , the order of microseconds. This response time is much faster than halogen and fluorescent.
- High d URATION and reliability , much longer than any other lighting system (about 50,000 hours).
- Low environmental impact, do not contain hazardous gases and metals to the environment.
- Light emitted no flickering.

The disadvantages include:

- High cost of Acquisitions.
- Low quality of the light, coldness.
- No allow to control the intensity of light generated by dimmers.

Because of these characteristics in the present, these lamps are ideal for applications where high reliability is required because of the number of hours of operation required and it is not important to the quality of the light.

Some of these applications for which they may be interesting type LED lighting are

- Lighting of parking of vehicles.
- permanent lighting corridors and circulation areas edifcio in crowded public.
- Outdoor Lighting.
- lighting paths and steps through beacons .

hoped that in future this type of lights are an alternative to low-energy lighting, a time will overcome the disadvantages cited previously.

How To Make A Flower For The Ear

is no longer mandatory to carry insurance on the car


some time, it is not compulsory to the receipt of insurance goes up when the vehicle is circulating.

has been deleted the requirement to keep the insurance bill provided that circuit.
Because of the principle that citizens have to present documentation that is already held by the government, the burden of proving that the vehicle is insured rests with the officers, who must check in the file
Insured Vehicle Information ( FIVA).

is curious how little publicity given to this rule that benefits drivers against the Administration.

It appears that the Traffic Department has not done too much grace this new right of drivers to be able to move without having to carry the receipt of insurance. In the press release where they do it publicly, is accompanied by other information intimidating (the penalties for driving without insurance, vehicles capable of the automated testing and lack of solidarity to be uninsured) and ends with one of his prized contradictions: "With This new measure is deleted for failure to carry proof, but from the DGT is recommended to attach other documents required of the vehicle. " So, now it is not mandatory, has come to be recommended. There

bear in mind that only in 2007 160,000 complaints were imposed not to carry the receipt of insurance. Since the penalty was 60 euros, is the not inconsiderable figure of just over 9.5 million euros.

Here are links to the press release from the Traffic Department in recognizing that it is no longer required.

nice treatment at Villa Turistica de Priego


I am pleased to put an article that praises the buenhacer of a company. This weekend I've been in Villa Turistica de Priego. This villa is located near Priego de Cordoba, and even closer to two other villages (Upper and Zagrilla Zagrilla Low) and has a special charm in a beautiful setting, where eagles and vultures are flying in the mountains and is also near the Bat Cave .


I had been on previous occasions, and again demonstrates the fact that always left satisfied, but this time have been overcome.


The deal has been great, fantastic, absolutely by all staff of the company. Receptionists, managers of the restaurant, the lady in charge of cleaning ... absolutely none. We left happy and eager to come back another time.

I recommend visiting this installation.

Good Rock Climbing Brands

Bad service Cortefiel


This I'll tell you I was in the store Cortefiel found in Córdoba in the central street of Tejares Round.

is not a place I used to frequent and usually not the kind of clothes I like (usually a type something classic, so much for my taste), but after what happened to me two Christmases ago I'm sure I'll never enter this establishment.

looking for a jacket for the winter and there were some that I liked. It was on the ground floor of the store. It was not cheap (if I remember correctly around 120 - 150 euros), but it looked quality.

The problem arose when I saw that the only color I had wanted in my size, was stained. Like a stain Colacola, across the back of the jacket.

I talked to the person who was there for if they asked for another, or had one in the store ...

The surprise I took when I told me to take the full price and try to get me the spot or take it to a dry cleaner and the stain out if I returned the purchase money, which not the cleaners. Alternatively

offered me this gentleman was that I discounted 10% of the price but I ran the risk that the stain out of the jacket.

The truth is that I thought cutrísimo for an establishment that I had an image of better quality and service unmejor. I think this is more like a market than a store that wants to have a certain category.

course and I will not Cortefiel.

Navy Blue And Yellow Walls

in unauthorized contracts Movistar Urende

This is something that has happened to a family that has fixed telephony Telefónica (though now called Movistar commercially) and a cell phone with Movistar prepaid card also.


It turns out that they called to offer to switch to a cell phone contract, to which she replied no and that was that.

Well a few weeks of that (in fact what happened as it has nothing to do with the call of business) arrives at the bank a fee of several hundred euros Movistar. When asked Movistar (or phone) about the post you say that a few days before had opened three mobile contract lines in your name and address to the same account where you have the landline.

had numerous calls (international, specifically to Peru) and could not tell anything else.

is incredible that this can happen and there is no rigid internal controls, and certainly I think that Movistar will be easy enough to find out who opened the contract (probably related to the numbers that made the calls), but possibly longer do not work there, as a minimum, if this is like my family tells me (and I have no reason to believe that not) will be forged the signature of the contract, committing a crime of identity theft.


is not the worst thing to happen, because when a company has many workers, everything is possible, if not the indifference with which the deal, without providing adequate care.

course have a complaint with the National Police, which also have advised him to fill the claim form and processed by the Office of Consumer Affairs. It has also issued an instruction to your bank receipt to return the abuse, which likely will generate nuisance calls or letters from companies specializing in recovery, with the corresponding threat of inclusion in a register of defaulters.


a little internet surfing I see that is something that is not the first time this has happened with Movistar. Here we have a similar experience, and other here.

Anyone else has happened something similar?

How To Slow Down Speed On Vba

Bioclimatic architecture:

The
facades of buildings are designed with corresponding holes whose purpose is to contribute to building natural ventilation, illumination light from the outside and allow their users to see the same environment.

In return the entry of sunlight produces a temperature increase in the interiors of the building and the consequent increased use of air conditioners and fans, increasing power consumption.

Proper building design factors should be considered as its location, its climate and geography. These factors allow the adoption of bioclimatic strategies to achieve thermal comfort and light naturally.

Among the multiple strategies of bioclimatic architecture to reduce solar gain in summer is the use of sunscreens both indoors and outdoors. Choosing the most appropriate types of protection depends on the building site and orientation of each facade. For guidance
South recommend the use of fixed guards or semi such as roof eaves, horizontal flight

For guidance West Northeast and recommended the use of Mobile sunscreens vertical or horizontal slats phones.

For guidance This and West recommend the use of sunscreens mobile, it's nice in cold weather or warm sunlight inlet at dawn or dusk.

The following table shows different types of sunscreens and energy savings can be achieved with each of them:

sunscreens and hot water heating boilers plant

The
boilers are elements in which heat is transferred from the combustion of a fuel fluid another heat transfer fluid responsible for the transfer of thermal energy to the facility. According

fuel type can be:
  • solid fuel boilers, coal, wood ...
  • liquid fuel boilers, oil boilers
  • gaseous fuels: natural gas, butane, propane ...
  • Multifuel boilers. The
boilers used in the residential sector and tertiary use water heated to temperatures below 110 º C heat transfer fluid.

case must be examined in each type of boiler used according to the application and needs.

One of the fundamental parameters in selecting the type of boiler used is the yield useful , which is defined as the ratio of useful power transmitted to the heat transfer fluid and thermal burn resulting available fuel at rated operating conditions:

useful
Performance (%) = 100 * Pu / Pc

The useful power is given by the amount of heat in kW transmitted to the heat transfer fluid is given by the following expression:

Pu = Q * (T -T s and ) * C and * P and

Where:

Q is the heat transfer fluid flow rate in l / h.
Ts: is the heat transfer fluid temperature at the exit of the boiler.
Te is the temperature of heat transfer fluid at the entrance to the boiler.
Ce: the specific heat transfer fluid.
Pe, is the specific weight of the circulating fluid. The

rated output is given by the type of fuel used by the boiler and the use of the same, according to the following expression: Pc =

PCI * C

Where:

PCI: is the lower heating value of fuel used.
C: is the amount of fuel consumed by the boiler.

In this performance standard boilers nominal service is reduced when operating at partial loads than the nominal power of it. This drop in performance should to be reduced despite the thermal power transmitted to the heat transfer fluid losses through the envelope remains constant, because tempeature must be maintained inside the boiler even though there is no demand.

The low temperature boilers able to improve part-load performance of diesel boilers. This improvement is achieved because the technology allows for adjustment of water temperature of production on demand, without having to maintain a minimum temperature inside. This will reduce the number of starting and stopping of the burner and substantially decreases diesel consumption.

The condensing boilers are those with better performance. The main difference with other types of boilers lies in harnessing the energy contained in the products of combustion gases, in particular energy uses steam condensation. The temperature of the combustion gases in standard boilers is about 150 º C, condensing boilers reduce the temperature to 65 º C by the use of latent heat in the flue gas.

The performance of the boiler combustion can exceed 100% because, as noted above, the performance tool is referred to PCI (calorific value). The PCI is defined as the total energy contained in the products of combustion of a fuel.

The following chart compares the distribution of energy losses in a low temperature boiler and a condensing boiler in relation to PCI.


When making an optimal choice from the point of view of energy efficiency be useful to consider both performance as a correct sizing of the nominal operating power in order to optimize performance and improve part-load performance season average. In

centralized facilities is also vital to make a proper control system programming of the facility.

The IDEA (Institute for Energy Diversification and Saving of Energy) provides a tool for accessing a database with various types of boilers on the market: http://www.idae.es/Calderas/Consulta . aspx
