COVID-19 corona latest news and advantages on world

      CORONA LATEST NEWS AND ITS ADVANTAGES ON WORLD AS A ENGINEERS VIEW SIGHT

        I am writing this on April 28, 2020. NOW TODAY DATA OF CORONA TOTAL POSITIVE CASE 30,64,830 AND DEATHS 2,11,609 it was a very big pandemic situation in world. currently 19,30,832 corona infected in 18,74,532 (97%) mild condition and 56,300 (3%) are serious condition. now top  five country USA, Spain, Italy, France, Germany highly positive case with increase ratio 7% in world. By the time I finish writing, these numbers will all have markedly increased.

      In that case some problem world face due to corona and out side some advantages on, also know world problem but i write down point on advantages due to corona.

      first due to closed world circulation of transport in atmosphere carbon dioxide level suddenly decrease, it was a vary difficult problem solve and that problem due to vary high effect on human body with immunity system. In pandemic situation human immunity system are sword work and high body security work.

    Second due to change of climate carbon dioxide major human disease are control.

    Third due to corona in fully worked people time spend on own family and filling happiness.

   

    Fourth due to corona online working awareness increase and can work from home.

    Fifth air quality has improve in lock down area.

Innovative architectural sculpture-16 story staircase in monfalcone, Italy

Innovative architectural sculpture-16 story staircase in monfalcone, Italy

    The structure which the architect fondly refers to as the Vessel is currently under construction in Monfalcone, Italy and the individual bronzed-steel and concrete pieces will not be assembled on site until next year. And even then, the project will be completed only in 2024.Looks like this architect is all set to create history with a collosal 16-story staircase sculpture in the center of Manhattan.

That sculputure design by Thomas Alexander Heatherwick, is an English designer and the founder of London-based design practice Heatherwick Studio.He described his creation as a huge climbing frame – 600 tonnes, 154 individual flights of stairs, 80 landings, and with 2,500 steps.

            The structure is the centerpiece of a $200 million, 22-acre redevelopment of the city’s Hudson Yards – an industrial area in the west of Manhattan, encircled by the High Line walkway.

         The project, which will be completed in 2024, is funded by billionaire developer Stephen Ross’s Related Companies, which is developing Hudson Yards with Oxford Properties Group.

For anyone who wants to enjoy the views at the top of the structure, but is unable to climb the 16-stories, an elevator will be included In a city full of eye-catching structures.

 Heatherwick didn’t just want the project to be a piece of eye candy, he wanted to create something that could be touched and used by anyone in the city.

     The inspiration for Vessel was taken partly from Indian stepwells and partly from the design of a jungle gym, one that can be found on just about any elementary school’s playground in the country.

   But Stephen M. Ross, the billionaire founder and chairman of Related Companies, which is developing Hudson Yards with Oxford Properties Group, has his own nickname for “Vessel”: “the social climber.” And the steep price tag Mr. Ross’s privately held company is paying for Mr. Heatherwick’s installation? More than $150 million.

self healing concrete for modern construction

SELF HEALING CONCRETE

   As revolutionary as it was and still is, modern concrete (Lime-based) has a short lifespan caused by the formation of cracks shortening the longevity of a particular construction. That’s how the concept of self-healing finds its way to concrete. the natural way of hydrates to seal cracks over time, and the artificial way to seal cracks which needs a man-made intervention. 

   PURPOSE 

• increase concrete’s durability

• huge positive impact on both the environment and economics

• improve the architectural designs

• change the shape of internal spaces so that it serves many functions and provides flexibility.

A self-healing material is described as a material that is capable of repairing itself back to the original state. The concept of self-healing concrete (SHC) that happens over time (autogenic) has been noticed for over 20 years. It can be observed in many old structures which have remained standing for long periods of time in spite of the fact that they have limited maintenance. This observation concludes that the cracks heal when moisture interacts with non-hydrated cement clinker in the crack. Nevertheless, in present-day constructions the cement is lowered as a result of modern construction methods. Hence, the amount of available non-hydrated cement is less and therefore, the natural healing effect is reduced.

The principal phases of the natural healing ability are the inflammation and hydration of cement pastes; followed by the precipitation of calcium carbonate (CaCO3), and lastly the obstruction of flow paths as a result of the deposition of water impurities or the movement of some concrete bits that get detached throughout the cracking process.  

Many factors are considered in the natural way of healing, such as; temperature, degree of damage, freeze-thaw cycles, the age of the concrete and the mortar state.As for the artificial way to repair cracks in concrete, which is man-made self-healing process was first invented in 1994. The main method and first approach was to use a healing agent (adhesive) which is encapsulated inside a micro capsule, once a crack forms, it causes the micro capsules to break, releasing the healing agent, hence healing the crack. The adhesives can be stored in short fiber or in longer tubes.

PROCESS OF HEALING CONCRETE

There are many approaches to create smart concrete and enhance its properties while reducing the cost of overall use of the material. Also known as Bio-Concrete; this kind of concrete uses a simple process to close the formed crack. The main mechanism is achieved by making a concrete mixture that contains (i) a precursor like calcium lactate (Ca(C3H5O2)2) and, (ii) bacteria planted in micro capsules (or just added to the mixture) that will later germinate, once the water reaches the crack. As soon as the bacteria germinate, they produce limestone (CaCo3) caused by the multiplying bacteria. Dr. Richard Cooper of Bath’s Department of Biology & Biochemistry says that incorporating bacteria in concrete adds a double layer shield in order to prevent corrosion in steel. Not to mention that it employs oxygen present which would then benefit the process of steel corrosion.

The bacteria which are applied in this kind of concrete are Spore-forming and alkali-resistant bacteria. Bacteria from this group are the most suitable as they are spore-forming and can live for more than 200 years in dry conditions [6 – p.102]. Therefore, using bacteria as a healing mechanism is one of the best mechanisms to produce this kind of concrete because of its sustainable organic properties.

FACTOR AFFECTING SELF HEALING CONCRETE

There are many factors that intervene with the usage of this kind of concrete. As it is noticed; it is not yet used in all new constructions as it is still being under development. Recently Self-healing bacteria-based concrete has been successfully tested on a full-scale. However, the cost of using it is still not determined as it is hard to predict a full cost. The cost efficiency is one of the most important factors and will determine whether the material will have limited usage restricted to spots that are hard to fix and important constructions such as bridges and highways.Other than cost, long-term efficiency is one of the important factors as well alongside the size of the formed cracks which must not exceed 150 millimeters of depth to establish an ideal result.All in all, some factors that will definitely determine whether SHC will be used as a replacement of concrete are; the economical factor, long-term efficiency, prospect suppliers and safety factors.

CONCLUSION

•  self healing concrete appears to be much more efficient than usual concrete.

•  It will definitely reshape how architects think and design.

•  we notice that it has more advantages than disadvantages and will transform concrete from an Eco-harming into an Eco-friendly material, 

• it reduces the CO2 emissions significantly. 

• the most promising approach is the bio-concrete which is bacteria-based due to its simplicity in comparison with other mechanisms. 

• For the meanwhile, architects must develop new design methods; ones that allow flexibility in changing functions easily for instance by providing movable partitions which allow creating bigger or smaller spaces depending on the current needs.

what is the Modular construction ?

Modular Construction

• What is the modular construction?

                   ‘Modular construction’ is a use of pre-engineered building units that are delivered to site and assembled as large volumetric components of a building. The modular units may form complete rooms, parts of rooms, or separate highly serviced units such as toilets or lifts. 

      

                  Modular construction is increasingly popular where a building is constructed off-site using the same materials and designed to the same standards as conventional on-site construction. It limits environmental disruption, delivering components as and when needed, and turning construction into a logistics exercise.

• where are they used?

            Modular buildings may be used for long-term, temporary or permanent facilities, such as construction camps, schools and classrooms, civilian and military housing, and industrial facilities. Modular buildings are used in remote and rural areas where conventional construction may not be reasonable or possible, for example, the Halley VI accommodation pods used for a BAS Antarctic expedition.^[2] Other uses have included churches, health care facilities, sales and retail offices, fast food restaurants and cruise ship construction. 

• Benefits of modular construction?

1. Rapid installation on site (6-8 units per day)
2. Economy of scale through repetitive manufacture
3. Low self weight leading to foundation savings
4. High level of quality control in factory production
5. Limited disruption in the vicinity of the construction site
6. Useful in building renovation projects, such as roof top extensions
7. Excellent acoustic insulation due to double layer construction
8. Adaptable for future extensions, and ability to be dismantled easily and moved if required
9. Stability of tall buildings can be provided by a braced steel core.
10. low waste construction.
11. environment friendly construction process.

• Application of modular construction

1. Suitable for buildings with multiple repeated units
2. Size of units is limited by transport (3.6m x 8m is typical)
3. Open sided units can be created (by changing the floor orientation)
4. Modules are stacked with usually no independent structure
5. Self weight of 1.5 to 2 kN/m²
6. 4 to 10 storeys (6 is usually the optimum)
7. Fire resistance of 30 to 60 minutes provided
8. Acoustic insulation is provided through double layer walls and floors.

•  Types of modular construction

1. 4-sided modules
2. Partially open-sided modules
3. Open-sided (corner-supported) modules
4. Modules supported by a primary structural frame
5. Non-load bearing modules
6. Mixed modules and planar floor cassettes
7. Special stair or lift modules.

3d printing of concrete

    3D printing of concrete

    3D printers are new generation of machine. They can produced different kinds of objective in different shapes and size. 3D printing is a type of addictive manufacturing technology where a three dimensional object is made.

        The 3D printing technology is used for both properties and distributed manufacturing in architectural, construction, industrial design, automotive, civil engineering etc.

How does 3D printer work?

    A 3D printer works by taking 3d computer file, from industrial standard software such as autocad and maya, and then a computing a large number of cross-sectional slices. Various phase of 3D mechanism.

   In the 1950 robotic bricklaying technology was conceptualized and explore and related in 1960s automated constriction began with plumped concrete and isoclynate foams.

   In early construction 3D printing development and research under way since 1995. A 3D  digital model of the item is created either by computer aided design(CAD) or using a 3D scanner. The printer lays down succesive layer of printing medium are joined or used to concrete them. These process can be sloe but it enable almost any shapes to be crated.

Benefits of 3D printing in construction.

• Reduce material usage 
• Saving 30% to 60% construction waste.
• Reduction production time 50% to 70% 
• Reduction construction  labour cost 50% to 80% 
• Environment freindly as recycled product or material are use.
• Possibilities of new shapes and design.

Information about civil engineering

       Civil engineering is a profesional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings.

       In general, civil engineering is concerned with the overall interface of human created fixed projects with the greater world. General civil engineers work closely with surveyors and specialized civil engineers to design grading, drainage, pavment, water supply, sewer service, dams, electric and communications supply.         
     General civil engineering is also referred to as site engineering, a branch of civil engineering that primarily focuses on converting a tract of land from one usage to another. Site engineers spend time visiting project sites, meeting with stakeholders, and preparing construction plans. Civil engineers apply the principles of geotechnical engineering, structural engineering, environmental engineering, transportation engineering and construction engineering to residential, commercial, industrial and public works projects of all sizes and levels of construction.

History of civil engineer

    In the 18th century, the term civil engineering was coined to incorporate all things civilian as opposed to military engineering.

     The first self-proclaimed civil engineer was John smeaton. He is the father of civil engineer.

    He was the constructed of eddystone lighthose.

   He below the picture.

           In 1771 Smeaton and some of his colleagues formed the Smeatonian Society of Civil Engineers, a group of leaders of the profession who met informally over dinner. Though there was evidence of some technical meetings, it was little more than a social society.

         In 1818 the Institution of Civil Engineers was founded in London, and in 1820 the eminent engineer Thomas Telford became its first president.

       The first private college to teach civil engineering in the United States was Norwich University, founded in 1819 by Captain Alden Partridge.

     Civil engineers typically possess an academic degree in civil engineering. The length of study is three to five years, and the completed degree is designated as a bachelor of engineering, or a bachelor of science in engineering. The curriculum generally includes classes in physics, mathematics, project management, design and specific topics in civil engineering.  some academic institutions offer post-graduate degrees (MEng/MSc), which allow students to further specialize in their particular area of interest.

      In this field in many opportunity in various jobs such as:

1. Surveying
2. Structure design
3. Estimating costing
4. Hydraulics engineering
5. Construction managment
6. Building material 
7. Construction technology
8. Irrigation engineering
9. Transportation engineering
10. Applied mechanics 
11. Waste water engineering
12. Geotechnical engineering
13. Environmental engineering.

What is the benefits of beard

    A beard is the collection of hair that grows on the chin and cheeks of human.
    In humans generally only in pubscent or adult males are able to grow beards.

    Through the course of historical sociatical attitude toward widely depending on factors such as cultural-religious and the current fashion trends.

    Some religions such as islam and sikhism have consiďer a full beard to be absolutely essential for all ables to grow.

He said: rasul allah (pbuh) said: Verily the majoos shave their beards and leave their moustaches, and we shave the moustaches and leave the beards, for it is the correct way.

Wasa'il al-Shee`ah, volume 2 page 102 hadeeth 1609, Hurr al-`Amili

     5 scientific reasons to keep growing your beard

1. Beards offer sun and UV protection to your face

2. 
   

   Beards make your skin blemish free

3. 
   

   Beards build an aura of ruggedness and masculinity

4. 
   

   Beards provide your face natural moisture

5. Beards act as air filters

       If you need to know that scientific reason open this link:

https://www.beardo.in/5-scientific-reasons-to-keep-growing-your-beard/

     Researchers from the University of Queensland in Australia surveyed 8,520 women broken into three different groups and rated their level of attraction toward men with beards. The women reviewed photos of men with different degrees of facial hair, from completely clean faces and light stubble to heavy stubble and a thick, full beard. After analyzing the photos, each of the three groups were asked to rate the men based on a set of specific questions.

Overall, women displayed a higher level of attraction to men with facial hair compared to the images of clean-shaven faces, but the women’s attraction to a man’s appearance during certain stages of his beard growth surprisingly depended completely on what that woman was looking for.

How to quite smoking???

      QUIT SMOKING

What is the smoking?

    

   Smoking is a practice in which a substance is burned and the resulting smoke breathed in to be tasted and absorbed into the bloodstream.

     Smoking generally has negative health effects, because smoke inhalation inherently poses challenges various physiologic processes such has respiration. Diseases related to tobacco smoking have been shown to kill approximately half of long-term smokers when compared to average mortality rates faced by non-smokers

List of smoking problem

• More than 480000 death every year for smoking.
• Lung cancer death
• Pulmonary disease
• Heart disease
• Damage blood vessels

Reduce risk

Just 1 year after quitting smoking, your risk for a heart attack drops sharply.

• Within 2 to 5 years after quitting smoking, your risk for stroke may reduce to about that of a nonsmoker’s.

• If you quit smoking, your risks for cancers of 

• the mouth, throat, esophagus, and bladder drop by half within 5 years.

• Ten years after you quit smoking, your risk for lung cancer drops by half.

How to quit smoking??

        If u have really change your smoking habits try this steps and better than before!

  9 step are change your life

• Think about benefits of smoking
• Find your reasone
• Pick the right day
• 40 days daily loudly speak I QUIT SMOKING
• Avoid smoking freinds
• Think about deases and benefits
• Eat healthy
• More drink water
• Reward from your self.
