What Is Low Sexual Desire? what is their symptoms?

People normally differ in the degree of sexual appetite they have. There is no single standard of sexual desire, and desire differs not only from person to person but also for the same person over one's lifespan.

One of the most common sexual complaints among couples is a disparity in sexual desire. Sexual desire can be low for a variety of reasons, many of them psychological and interpersonal. But that doesn't necessarily make it a disorder. It becomes a diagnosable condition only when it diminishes the quality of one's life and creates distress, or a disparity arises in the sex drives of partners, evolving into a matter of unresolved contention in the relationship. Loss of sexual desire can both result from relationship problems and cause them.

Moreover, what constitutes "low" (or hypoactive) sexual desire is relative. Partners who use the degree of sexual desire experienced early in a relationship as a standard of comparison may label as a problem the drop in sexual desire and activity that often accompanies long-term partnerships. Further, a person who experiences low sexual desire that is problematic relative to one partner may not experience any disparity in desire with a different partner. What is designated as one partner's low level of desire may more accurately reflect a hyperactive sex drive in the other partner.

Sexual desire and responsiveness normally differ between men and women, and assumptions about sexual equivalency may falsely suggest the existence of hypoactive desire disorder. Men are more readily physiologically aroused than women, and, for them, desire is tied tightly to this arousal. Among women, sexual desire is typically more psychological and situational, influenced by how they feel about their bodies as well as the quality of relationship with their partner. Moreover, women often do not experience desire until after they are genitally aroused, and arousal may require an extended period of foreplay.

The waning of sexual desire is sometimes considered inevitable in a long-term relationship, but it is unclear whether that is truly the case or whether it is a function of age or familiarity. Low sexual desire can often be treated. Increasingly, experts are optimistic that the sexual spark can stay alive throughout the lifespan.

Make Sure You Properly Use Heaters When Installing Bearings

One of the reasons that bearing heaters are important for installing and dismounting bearings into rotating equipment is it will cut down on operating costs. The bearing heaters are designed to heat the bearings and virtually eliminate the pounding and hammering process that takes place with cold-mounted bearings. The heating of the bearings also de-magnetizes them, reducing any possible risk to the operator from torches, oil baths, and flames.

Why do you need to heat the bearings?
The heating process allows the bearing to be precisely aligned and placed on the shaft without any risk of damage. When a cold bearing is placed on a shaft, the bearing has a tendency to become misaligned, requiring the operator to pound it into place. If the bearing is not precisely placed on the shaft, it would only take a misalignment of 0.001? to reduce the life of the part by up to 50%. Not only does heating the bearings save money in parts, but also it will save money from having to pay the operator to make the replacement sooner than the recommended specs on the part.

Why Should You Use a Bearing Heater?
The heating of the bearings is an important process in the installation and removal of the parts because heated bearings are easier to place into the equipment. The bearing heater provides both even and clean heat, allowing the operator the ability to place the part into the equipment precisely, extending the life of the parts because of less friction and wear. Compared to messy alternatives like forging or oil baths, the bearing heater is the most efficient of all bearing preparation methods. Processes like forging can create uneven heating surfaces, causing hot spots that will change the bearings metallurgical properties.

The 5 Things to Look for in a Bearing Heater
Before you simply choose the most affordable bearing heater, consider some of these important aspects of the process so that your heater can provide convenience and efficiency to the projects.

1. Being Portable. Consider a bearing heater that is portable and can be brought to the area of the shop where the work is taking place. Larger heaters that are extremely heavy can not be moved around the shop, requiring the operator to bring the bearings to where the heater is installed. This will become an inconvenience over time, especially when you work in a busy environment and are trying to get more than one thing done at a time.

2.Flexible Heaters. If your maintenance shop makes use of a bearing heater, there are going to be a variety of sized bearings that you will be working on throughout the year. Choose the right bearing heater that can accommodate a variety of sized bearings. Many heaters can handle different sizes from the small, medium, light-duty, large to heavy-duty bearings.

3.Reduction of Magnetization. When your facility uses induction heaters to treat the bearings, a surge of electricity runs through the bearing to cause it to heat. This process can often magnetize the entire bearing, resulting in a much shorter lifespan for the part. Consider a bearing heater with a cone-shape design, heating the inner race of the bearings without the use of the electrical surge, eliminating any magnetization from the bearing heating process.

4.The Thermostat. In a busy shop, the operator often does not have the time to stand idly by watching and waiting for the bearing to properly heat up. Consider a bearing heater than is equipped with a thermostat, ensuring that the bearings will be able to reach and maintain the desired temperature until the installation process is ready to begin. The thermostat will allow the operator to increase productivity and ensure the bearing is the appropriate temperature each and every installation.

5.Ease of Usage. The heating of the bearings should not require a degree in rocket science. Consider a heater that is made of high-quality components and put together by skilled workers. Choose the manufacturer carefully, looking at their track record and the guarantee they place on their equipment. In order for your facility to remain efficient, the bearing heater must operate without malfunctions and problems every day. The unit should be easy to use, provide consistent results each time, and allow any worker in the company to operate easily.Properly heated ball bearing units are a vital process in the installation and dismounting of the bearing within rotating equipment. Not only will the bearing heaters provide a more evenly heated part, but also the process will go faster, and the parts will last longer. Over the course of a year, the time and money saved by using these heaters is substantial.

Design and Characteristics of Ball and Roller Bearings

DOUBLE ROW SELF-ALIGNING BALL BEARINGS utilize an inner ring with two rows of balls, in two deep raceways; and an outer ring with a single spherical raceway.  In this way, the inner and outer rings can be misaligned relative to each other.  The resulting affect is a comparatively large angle imposing moment loads upon the balls.

The boundary dimensions of the 1200 and 1300 series are the same as the 6200 and 6300 single row deep groove bearings.

CYLNDRICAL ROLLER BEARINGS have rollers which are essentially cylindrical in shape.  This provides a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring.  The cylindrical shape allows the inner ring to have axial movement relative to the outer ring (except the NH type).  This is especially important when accommodating thermal expansion when both rings must be press fitted.

In this series, the NJ, NF, and NH types can carry light or intermittent thrust loads.  The bearings utilizing machined bronze cages are suitable for high speed operation.

The NN3000 and NN3000K series are available in high precision tolerances and are well suited for use in machine tool spindles.

TAPERED ROLLER BEARINGS utilize conical rollers and raceways arranged so that the rollers and raceways meet at a common apex.    The rollers are guided by contact between the large end of the roller and a rib on the inner ring.  This provides high capacity for radial and single thrust loads.

SPHERICAL ROLLER BEARINGS have two rows of rollers in separate raceways which allows the bearing to compensate for angular errors.  They have large radial and thrust load capacity for heavy shock and impact loads, suitable for heavy industrial equipment.

DUPLEX BEARINGS use a set of two on a common shaft with the inner and outer rings clamped solidly together.  They are used to gain axial shaft control, rigity and extra capacity.

There are three fundamental combinations n duplex bearings: face to face (DF); back to back (DB); and tandem (DT).

The back to back mounting (DB) has the load lines through the balls converging toward the outside of the bearing.  This arrangement is preferred when the pair of bearings is to resist moment loading.

The face to face mounting (DF) has the load lines through the balls converging  towards the axis of the bearing.  This arrangement is less sensitive to slight angular errors in mounting of the bearings.

The tandem mounting (DT) is arranged so that the load lines through the balls are parallel to each other.  This mounting is used when it is desired to divide a heavy thrust load between the two bearings.  Since this mounting carries thrust load in one direction only, a third bearing should be provided to take thrust load in the reverse direction.

SINGLE DIRECTION THRUST BALL BEARINGS consist of two washers having ball grooves ground into their adjacent faces with balls and cages mounted between these grooves.  They are normally equipped with either pressed or machined cages and are suitable for carrying thrust loads at moderate speeds.

DOUBLE DIRECTION ANGULAR CONTACT THRUST BALL BEARINGS are back to back duplex bearings with a larger contact angle than that of normal angular contact ball bearings.

These bearings have been recently developed, and are primarily designed as thrust bearings for machine tools.  They utilize machined brass cages.

SPHERICAL ROLLER THRUST BEARINGS are similar to double row spherical roller bearings, but have a greater contact angle.  They are guided by ground flanges on the inner ring and operate against the spherical raceway in the outer ring.  The contact angle is approximately 45⁰.  Machined cages are normally used and oil lubrication is recommended.

2 months left students await photocopies of answersheets

Aurangabad: Inordinate delay in receiving photocopies of their answer-sheets has forced some post-graduate students of Dr Babasaheb Ambedkar Marathwada University (BAMU) to appear for fresh exams. The students alleged that more than two months have passed since they applied for the photocopies, and they have had no choice but to give their exams again.

We had applied for a photocopy of the answer-sheets through our college on January 7 by paying requisite fees. In my case, I had sought photocopies for three subjects. I failed in one subject and got less marks in the other two. While around a months time was expected to get access to photocopies, we have still not received them,said one of the affected students. He added, It is a mockery of education system. 

Throughout the last two months, we have been eaten with uncertainty over the previous marks and worries about the upcoming exams. When contacted, BAMUs officiating controller of examination, Pralhad Lulekar, said the varsity has cleared all applications seeking photocopies of answer-sheets
