KP Astrology: The Four-Step Theory for prediction

The Four-Step Theory: The Basic principle of KP is that a planet gives the results indicated by its Star Lord and Sub Lord.

The four steps to determine the KP coordinators are as follows:
        1. The planet position (House position in Bhav Chalit chart)
        2. The Star-lord of the planet (Same house resident, houses owned)
        3. The Sub Lord of the planet
        4. The Star-lord of this sub lord

Very easy rules of KP Astrology:
            a. Every house will have supporting houses and opposing houses
            b. For every event, the sign lord tells about the main source of the event.
            c. The star lord gives the main results
            d. The sub lord tells about the quality of the event.
            e. The 12th house to every house negates the main event related to the house.
            f. The 2nd house to every house will add to the good results of the house.
            g. The Cuspal sub lord of every house tells the promise of that house event.

Always remember:

            I: If Starlord opposes the sub lord, then the power of the sub lord decreases, and this can either delay or deny the event.
            II: The ruling planets and the running Dasha lord significators if display the same script then the event can be expected.

Advantages and disadvantages of Moisture curing coating, sealant, adhesives, materials:

A moisture-curing product is cured due to the presence of moisture in the atmosphere. These form a protective coating/matrix / reach the final stage by reacting chemically with the moisture in the air. Moisture curing materials are more applied on roofs, the outer surfaces of buildings, and on marine equipment and vessels because they can cure in the moist air for works like flooring, tiling, insulation, roofing, and wall covering.

These systems require moisture to trigger the curing reaction. Moisture cures react with moisture in the environment or the underlying layer in order to cure. While this curing process can take days to complete, moisture cure adhesives have unique uses for the bonding and use of construction materials.

Below are few points (Moisture cure coatings, moisture cure sealants, moisture cure adhesive):

1.     Moisture-cures are that they offer resistance to ponding water.

2.     Moisture curing sealant/coatings/material produce a highly reflective surface and possess good adhesion properties.

3.      Moisture-curing coatings also prevent pitting corrosion and bacterial corrosion on marine machinery.

4.     Generally, they come in one component

5.     Moisture cures show good thermal-mechanical and weathering properties and are widely used in reactive hot melt adhesives and coatings.

6.     Moisture cures bond with surfaces that are difficult to bonds, such as wood-based materials, untreated metal, or plastics, delicate and thin materials, like plastic panels, glass, and sheet metal fascia.

7.     Moisture cures act as insulation material at exterior applications that may be exposed to temperatures in excess of 100 degrees.

8.     Moisture cures show the high elastic property in a very vast temperatures range.

9.     Moisture cures can be applied on damp surfaces and even in very low or negative temperatures.

10.  Moisture cures forms: Permanently elastic, vibration-damping, compensate different thermal length expansions, Low to high viscosity for optimal application, Instant seal, Resistance to oils and chemicals, Flame retardant, Low to high thermal conductivity, Long-term resistance to harsh weather conditions, etc.

Numerology - Challenge Number

There are usually considered to be four challenge numbers, and each of them covers a different portion of your life. These challenges are designed to inspire and help you learn specific lessons over the course of your life’s path. You will find yourself placed in a circumstance that causes you to work on the specific traits portrayed by your challenge number. The main challenge lasts from birth until the end of life. This is the only place in which zero will appear in Numerology.

To calculate your challenge number, the date of birth is put into use. Challenge numbers may be negative in nature, but they are not meant to be overcome. Instead, they tell you what you are to become. In Numerology, challenge numbers are calculated through subtraction and not addition like in most numbers.

In Numerology, there is no negative number; therefore, one can comfortably subtract a larger number from a smaller number. For example, 1 – 9 = 8. No negative sign should accompany the results you get.

The Formula for Finding Challenge Number

Day of Birth – Month of Birth = First Challenge Number - Birth to age 30-35.

Year of Birth – Day of Birth = Second Challenge Number - Age 35-55 or 60

Second Challenge Number – First Challenge Number = Third Challenge Number - Constant throughout life and this is considered as main and very important

Year of Birth – Month on Birth = Fourth Challenge Number - after 60

For Ex: DOB : 22/12/1980. 

First Challenge Number: 22-12 = 10 = 1

Second Challenge Number = 1980-22 = 1958 = 14 = 5

Third Challenge Number = 5-1 = 4

Fourth Challenge Number = 1980-22 = 1958 = 15 = 6

Challenge Numbers are 1, 5, 4, and  6.

What does Challenge Number says?

Challenge Number 0: There really are not many obstacles in your path if your challenge number is 0. You are capable of growing and learning during this period without any particularly serious challenges. That isn't to say there will be none, but there will likely not be any that are overtly difficult or life-changing.

Challenge Number 1: As the one stands alone, so a challenge number of 1 signifies a need to learn independence. You might find yourself in a position of needing to stand up for yourself in any number of ways: your values, your faith, your own well-being, etc. Self-assertion will be a running theme during this period of your life.

You will learn the advantages of individuality. Your desire for that will overshadow societal pressures of conformity. The need to assert your will is likely to manifest with aggression at times, fear and isolation at others. As a result, you will find your identity. You will develop balance and realize your independence. You will learn the value of intuition and learn to trust your own. The effects of 1 are lessened when it is one of your core numbers.

Challenge Number 2: Hyper-sensitivity to other people's criticisms can prove to be an obstacle. Paranoia and suspicion will keep you from allowing yourself to be vulnerable. You will view yourself in a critical or self-deprecating way and your inhibitions will show in every area of your life, especially in terms of love and relationships. Trusting will be a major challenge for you during this period, but it will be learned and tested over time, beginning with yourself.

You are likely to have trouble wrangling your emotions. You will hold onto anger and grudges for periods of time that are disproportionate to perceived offenses and your own inability to forgive or accept forgiveness could have a paralyzing effect on your emotions. You have a keen sense of awareness and excellent intuition but you don't know how to use them productively. Instead, you choose to fear them and sink further into yourself. On a positive note, that hyper-sensitity will also make you empathetic and compassionate. You will be able to feel others' pain because you relate to it so well.

Challenge Number 3: Self-criticism can stifle your creativity and sense of identity. Self-doubt can hold you back from making good impressions on people. In any circumstance where you sense failure, you ruthlessly attack yourself on the inside while masking your feelings of self-loathing with self-deprecating remarks cleverly disguised as sarcasm and humor. Your sense of humor is unnaturally amplified and comes across as forced.

The offshoot of all this is that your ability to express yourself in less direct ways is heightened. You may find yourself writing your own biography or self-analysis through creative outlets like writing or art. You will learn self-respect and others will start treating you in a manner commensurate with these newfound self-realizations. Your True Self will emerge and will guide you either into your next challenge or through the remainder of your life.

Challenge Number 4: Your organizational skills will leave much to be desired. You may have attention deficits or simply lose interest in tasks before carrying them out to completion. You may find yourself emotionally invested in things that are of little value. You may cling to a partner with whom you have no positive future. Your need to idealize things may overshadow your ability to see the reality of situations.

You will learn the value of paying attention to detail and finishing what you start. These will be serious challenges but they will result in exponential personal growth in the long term. You will learn how to organize your life and manage your emotions. You will learn to let go of things that do not serve you. Efficiency in action, thought, and emotion will be achieved. The real challenge, however, will be in the learning. You will not obtain these skills without first conquering many personal demons.

Challenge Number 5: Your lust for life will get in the way of establishing priorities. Your need to be free will lead to bondage in many facets of life from finances to emotions to relationships if you do not make a conscious effort to prevent it. You will be prone to succumbing to dangerous vices involving drugs, alcohol or sex. Anything that stimulates the senses can distract you from the things in life that really matter. Your need for self-gratification will make you over-indulgent. It will overshadow your common sense and cause you to do things you know to be harmful. This will cause you to abandon things when they no longer interest you. This includes tasks, projects, even relationships.

You will have to work on drawing things into your life that will have a grounding effect. Yo will have to learn how to step back and let your rational mind deal with your impulses. Over time, you will become capable of making better decisions and carrying on long-term relationships but getting to the point of settling down could take a while.

Challenge Number 6: You will find yourself setting the bar unrealistically high in many facets of your life. Your sense of idealism will prove to be unrealistic and unattainable, making life difficult for you and for anyone whose lives touch yours directly. Unable to feel like anything in your life is good enough, you will lack gratitude. You will have trouble seeing the good in yourself, in others or in the world. You will ultimately have a very fatalistic outlook on life and become very cynical, jaded and judgmental.

You will find yourself going through life with blinders on. You will have trouble seeing anyone's point of view but your own in any situation. You will find yourself asserting your values on others and judging them when they fail to meet your high moral standards. In fact, your insistence on always being right will be perceived as overbearing and arrogant. This will have an alienating effect on you and will cause people to want to create distance between you and them. You will have to work hard to find a way to be satisfied with your own capabilities and accept that they will likely never meet with your ideals. The obvious solution will be to re-define those ideals to be more realistic and attainable.

Challenge Number 7: Matters of faith and spirituality will be major obstacles during this period of your life. You will become very skeptical of anything that does not carry with it tangible proof. You will find it nearly impossible to believe anything you cannot observe or touch. This includes your relationships. You will question the motives of anyone who says they love you because even action can be deceiving. Love is not something you can hold in your hand so, abstract as the concept is, you will have a difficult time accepting it.

Your tendency to shut out the holistic aspects of life will make you feel stagnate on the inside. Your own personal growth will seem to have come to a stand-still. Eventually, you will have to learn how to appreciate the intangibles, to take the occasional leap of faith, to simply enjoy yourself without keeping up your constant guard. Your challenge will be to discover a philosophy, ideology or religion that resonates with you – something you can believe without needing proof. You will need to learn that there is a qualitative difference between fact and truth and learn to see the latter even in absence of the former.

Challenge Number 8: Your lust for power and money drive everything you do during this period of your life. You are so driven to succeed and to rise through the ranks – whether real or imagined – that it proves to be a detriment to your sense of self. In the eyes of the people in your life, you come across as more mechanical than human. The more this manifests, the less capable you become of connecting with your own emotions. You have difficulty sensing your higher self. In your mind, you start to become a soulless entity, much like a machine.

With success comes the accessibility of material things. You succumb to their lure. You do things most people would consider unscrupulous. You will develop a reputation for being over-competitive and unfeeling. Indeed, you will have difficulty with things like compassion and empathy. In short, your lust for power will cause you to steamroll over other people's feelings and ignore their needs in favor of achieving and obtaining those things which you desire. You may hurt a lot of people pursuing your own interests but it will not occur to you to care... at least not for a while. Your challenge will be to learn that there are things that are more important than accumulating “stuff.” You will have to come face to face with the realization that “he who dies with the most toys...” still dies and that there are intangibles in life that have value that transcends that of material things. In short, you will learn that there is such a things as, “enough” and you will learn to be satisfied with the life you live.

Challenge Number 9: Challenge number 9 mirrors that of 0. Both ends of the spectrum carry with them a sense of stability that makes the challenge period much more manageable than those associated with other numbers.

Numerology - KUA Number / Angle Number

KUA Number / Angle Number are indications of good Directions and bad Directions - For Your Health, Wealth, and Happiness.

KUA Number / Angle Number – Calculation.
For Ex: DOB = 01-01-1980
Consider only yyyy = 1980 = 1+9+8+0 = 9
If you are male = 9-11=2
If you are female = 9+4=13 = 1+3=4

As said, KUA Number / Angle Numbers indicates directions, every single KUA Numbers / Angle Numbers directions from 1-9 is associated with 8 different directions (or call it as Eight Mansions) for different purposes which come from eight different elements (like sky, earth, thunder, wind, fire, water, mountain, and marsh (body of water/lake)). Also, every KUA Numbers / Angle Numbers will have 4 good and 4 bad group directions as follows:

The East Group Kua numbers are 1, 3, 4 and 9.
The West Group Kua numbers are 2, 5, 6, 7 and 8.

You can consider in your home, office, city, state, country, and even in globe.
Find the below details:

This is called as Pa Kua chart or Bagua Energy Map of your home.

In these directions, you can face while sitting, sleep, spent time, maintain entrance door, etc. This KUA Numbers / Angle Numbers says about the Vastu remedies, what images we can hang up, what idols we need to install, what color we need to have in which part of room of house.

KUA Numbers is called as Angle Numbers, you can write this number and keep in front of you always or write this number on hand, palm and wish for the best of luck.

Suppose, you have no way that you have to face the direction which is bad for you, then what to do???

This portion will be update soon…

Bio Concrete / Self Healing Concrete

Accidently, human bones gets cracks and doctors used to put Plaster Of Paris by keeping the bones in exact position without disturbing the fractured bones. Look at small video:

Thanks to ORTHOfilms for the video.

Why does concrete cracks: Please refer to this blog to know more about this. https://annayyachandrashekar.blogspot.com/2017/11/blog-post.html

Microbiologist, Mr. Hendrik Jonker used the same system to heal the concrete as human bones does. He mixing concrete with limestone-producing bacteria ( Bacillus pseudofirmus or Sporosarcina pasteurii, are found naturally near volcanoes, and they are capable of surviving for up to 200 years without oxygen or food) and tested. Once concrete cracks, water and other particles starts entering in to the concrete, including the mixed bacteria, and get activated with water, bacteria use calcium lactate as a food source and produces limestone in a result which closes up the cracks.

 

Because of modern technology and advanced science, now we are able to make the concrete to repair the cracks itself. This concrete is named as Bio Concrete / Self Healing concrete. Since, this concrete gets it ability of self healing because of use of some bacteria, hence it is also termed as Bio Concrete. And, as this concrete can repair/ heals itself, it has been named as Self Healing concrete.

 

In fact, Self Healing Concrete is available in 2 different types and are as follows:

1. Biotic Concrete

2. Abiotic Concrete 

In direct method, agents are directly added to the cement mixture while making concrete in a designed ratio. Whereas, in Encapsulation method, self-healing agent is capsulated (using a different type of shell material and geometric properties) and added in concrete.

Microbial enhanced crack-healing ability is presumably due to combined direct and indirect calcium carbonate formation:

i) Direct CaCO3 precipitation through metabolic conversion of calcium lactate.

ii) Indirect formation due to reaction of metabolically produced CO2 molecules with Ca(OH)2 minerals present in the concrete matrix leading to additional CaCO3 precipitation.

Advantages of Bio Concrete: No need to replace the old concrete at all, decreases concrete maintenance cost (repair costs of steel reinforced concrete structures such as building, bridges, dam and others)  and improves the strength and durability of the concrete. Bacteria feed on oxygen, so, tendency for the corrosion of reinforcement can be reduced. Self-healing bacteria can be used in places where humans find it difficult to reach, so it reduces risking of human life in dangerous areas. Crack will be healed in the initial stage itself thereby increasing the services life of the structure than expected life.

 

Disadvantages of Self-Healing concrete: Cost is high as it quite new in market BUT, maybe in future, the cost gets reduce when self -healing concrete will become common. Still no any constructions codes were made to use / test / approve the Self-Healing concrete. You will not get Contractor / applicator to install this at present. Volume of self-healing agents such as bacteria and calcium lactate mixed will lose it’s volume once get reacted, then, it will leads to the reduction the strength of the concrete.
