Ruchinilo from IIT Guwahati made an agricultural app for mobile Get Timely Advice & Assistance from Experts

One Man Made an App to Help Farmers Get Timely Advice & Assistance from Experts around the Country
In April 2015, Ruchinilo graduated from IIT Guwahati with a Masters in Development Studies
What’s more impressive is that the entire initiative required no funds: “I have a background in programming and assembled the app myself, using open data sources,” Ruchinilo says.
“If I buy phones to give them, they will have a sense of indebtedness to me. They will think of it as an act of charity and will not have a feeling of ownership, of entitlement about it,” explains Ruchinilo.
Determined to ensure that the farmers developed a sense of ownership about the project and viewed him not as a donor but as a partner in their development, Ruchinilo urged the farmers to pitch in and buy common smartphones or use existing phones for their respective communities.
“I used Information Communication Technology (ICT) in the form of a mobile interface to develop an app for farmers where, if they are facing any problems, they can reach out to experts. They can also use the app to create reports about their farm and build a knowledge bank. This will prove to be very useful to the communities in the future,” he explains.
“The objective is to connect farmers with individuals who are experts in the agriculture sciences in order to promote knowledge sharing and sharing of best farming practices,” Ruchinilo elaborates.
With the app, a farmer can reach out to five experts in different parts of the country. He can communicate using photographs, videos or even text messages in his mother tongue.
Queries and requests for help from the farmers are then picked up by the Cloud. These make their way to Ruchnilio and his team, who filter the messages and direct them to the appropriate experts.
The project was launched in October 2015 and, in just eight months, the app has already met with resounding success. “In the months of January and February, we saw close to five or six queries from farmers a day,” Ruchinilo says.
The app has helped 44 farmers in nine villages across Udaipur district connect with experts who can help them efficiently navigate the choppy waters of being a farmer in India.

Oxytocin “the feel-good” hormone”





Oxytocin “the feel-good” hormone”

Oxytocin has other benefits as well like making you feel more aroused, increasing feelings of trust, lowers heart rate, reduces blood pressure and simply makes you more ready for sexual interaction. 
Skin to skin touching (with intimacy, a massage, intercourse, or cuddling) is all that is required. Also involved in sexual responsiveness and orgasm, the hormone oxytocin counteracts stress and depression by combating the harmful effects of cortisol and reduces blood pressure. It has also been shown to improve gut motility and decrease intestinal inflammation.

One of the most prevalent benefits of sleeping naked is that it let’s your body cool properly at night better. Doing this helps to maintain healthy (more balanced) cortisol levels. Cortisol is also known as the stress hormone as i’m sure you’re aware. The higher your cortisone levels the more you are at risk for certain health conditions. Conditions like high blood pressure, higher than optimal cholesterol levels, as well as other imbalances, weaker immunity and increased appetite which is weight gaining effects. Cortisol is also a fat storing hormone so the higher your cortisol levels the more your body will store fat. The cortisol levels in the body are usually lowest when you are sleeping deeply  (between 10 p.m. and 2 a.m or so) But after deep sleep your cortisol levels start to rise again in order to wake you up in the morning. Want to lower your stress levels and help the body release fat stored by cortisol? Sleeping naked is a step in the right direction. Sleeping naked keeps you cool which helps cortisol levels.

Sleeping naked does in fact stimulate oxytocin which is a feel good hormone. This is also known as the “love hormone” which also happens to be released when you are experiencing sex and orgasm. It is a hormone that helps fight depression as well as contributing to gut health and a healthy blood pressure levels. Sleeping naked with your partner can light the flame and increase your sex-drive and physical connection.

When we sleep in total darkness, melatonin is released, triggering a very slight but critical cool-down in the body. As body temperature drops, growth hormone is released and works its regenerative magic.


6 amazing health benefits of sex in a loving relationship
Majority of relationship therapists will tell you that not having sex with your partner frequently enough (at least twice a week) will make either or both of you unhappy, frustrated, depressed. Research shows people who have intercourse (not masturbation) at least once or twice a week are better placed to live longer due to the companionship, happiness and pleasure they both bring.
One passionate sex session and all your problems are gone.

1.      Sex helps your heart: Having sex at least twice a week will heavily reduce your chances of having a heart attack and helps maintain a healthy heart.

2.     Sex relieves stress and tension: This is because the feel good hormones – endorphins and oxytocin – are released during sex.

3.     Sex relieves pain: Studies show that after you orgasm, the hormones released will actually help stop your pain; headaches or any other body pains.

4.     Sex makes you feel and look great: The more sex you have the more hormones like testosterone and estrogen are released into the body and this helps keep your body looking young and fresh. If you want softer skin and shiny hair, then estrogen is your answer.

5.     Sex helps you sleep better : A relaxed sex session, which results in an orgasm, will release the hormone prolactin. This is the hormone that is heavily linked to a good night sleep.

6.     Sex fights disease: People who have frequent sex have a higher level of an antibody called immunoglobulin A (IgA). According to research, these antibodies help combat diseases

Moving Bed Biofilm Bioreactor (MBBR) -Design and Construction Principles of FMR






Moving Bed Biofilm Bioreactor (MBBR) process uses the whole tank volume for biomass growth. It uses simple floating media, which are carriers for attached growth of biofilms. Biofilm carrier movement is caused by the agitation of air bubbles. This compact treatment system is effective in removal of BOD as well as nitrogen and phosphorus while facilitating effective solids separation.

Design and Construction Principles

MBBR units are placed in series based on the load entering each reactor. Neutralised and settled wastewater passes through MBBR for reduction in BOD/COD. Most of the MBBR plants are provided with vertically or horizontally mounted rectangular mesh sieves or cylindrical bar sieves. Biofilm carriers are made up of high density (0.95 g/cm3) polyethelene. These are normally shaped as small cylinders with a cross inside and fins outside. The standard filling of carrier is below 70% with a maximum specific area not more than 465 m2/m3. Generally, design load for COD-BOD removal is 20 g COD / m2d. Smaller carriers need smaller reactor volume at a given loading rate (as g/m2d) when the carrier filling is same. 

It is advisable to use MBBR in combination with a septic tank, DEWATS or a pre-coagulation step as a pre-treatment unit, depending on the local conditions and input characteristics. It is a very robust and compact alternative for secondary treatment of municipal wastewater, having removal efficiency for BOD 90 – 95% (low rate) and that of 75 – 80% for high rate. Average nitrogen removal is about 85%. There is no need for sludge recirculation. Phosphorus and faecal coliform reduction is feasible with additional passive (non-mechanical) or active (mechanical) system components.

A constantly operating MBBR does not require backwashing or return sludge flows. It has minimal head-loss. Coarse-bubble aeration in the aeration zone in the wastewater treatment tank provides ease of operation at low-cost. Agitation continuously moves the carrier elements over the surface of the screen thus preventing clogging. Maintenance of MBBR system includes screening, influent equalisation, clarifier system, sludge handling and integrated control system. There is no need to maintain f/M ratio as there is self-maintenance of an optimum level of productive biofilm. Skilled labour is required for routine monitoring and operations of pumps and blowers.

You always need expert advise to design a efficient and cost effective system.

DESTINY FATE IN ISLAM IN NUTSHELL

DESTINY FATE IN ISLAM IN NUTSHELL


Tawakkul means putting in one’s best efforts—leaving no stone unturned, and then putting one’s trust in Allah and not in one’s own efforts or availability of the means one has, because whatever the outcome, it comes about only with the approval and decree of Allah and not otherwise. It is reported that one day Prophet Muhammad (SAW) noticed a Bedouin leaving his camel without tying it and he asked the Bedouin, “Why don’t you tie down your camel?” The Bedouin answered, “I put my trust in Allah.” The Prophet then said, “Tie your camel first, then put your trust in Allah.” 

To work and to strive is within the ability and the limits of man..whether the striving is accepted or not, or whether the desired result is achieved or not is entirely in the Blessed Hands of the Lord Most Majestic Who Created Alone!.

OPERATION MANUAL FOR 10 KLD ETP CHEMICAL DOSE OF ALUM

OPERATION MANUAL FOR 10 KLD ETP

OPERATION INSTRUCTION :

1.         The total quantity of waste water from kitchen for which the ETP is designed is 10,000 liter per day. The unit functions 8 hours in a day .There is no flow at day.The ETP is designed for continuous flow treatment of effluent at a average flow rate of 1250 liter per hour. The air blower will have to be run continuously for mixing of chemicals in reaction tank and flocculation tanks.
2.         Allow all the effluent of the day generated to enter the underground collection tank. Collected effluent is planned to be pumped continuously for eight hours at a average flow rate of 1250 liter per hour . The plant and machinery cant take more than this flow.
.

CHEMICAL DOSING  :

1.   Lime, add 20 Kg per day to maintain pH at 10 at collection tank. Check pH at Collection tank after adding lime manually. pH maintaining is extremely important or alum will not work properly. Use it up in one day.
2.    Alum, add 15 Kg in the auto doser tank of the reaction tank in 100 liter of water and use it up in one day. pH will come down to 8 after addition of alum.
3.   PAC, add 100 gm in the auto doser tank in the flocculation tank and use it up in one day.


COMMON INSTRUCTION FOR ETP  :
1.   When the pumps are on, the blower must be on also for mixing the chemicals with water. Note down the time in log sheet.
2.   The Auto doser for alum in reaction tank should be on when pump is on. Note down the time in log sheet
3.   The Auto doser for PAC in flocculator should be always on continuously when pump is on. Note down the time in log sheet
4.   Fill the auto doser tank with fresh water and mix the estimated chemical in it for the day and set it at the desired dose. Note down the time and quantity in log sheet
5.   Preventive maintenance of pumps and blowers like oiling etc should be regularly done.
6.   Note down the pH of the inlet and outlet water and note it at log sheet.
7.   The waste sludge from tube settler is to be suitably disposed off to the sludge drying bed by opening the valve provided at the hopper bottom of the tube settler.
8.   Backwash the Sand filter and carbon filters after each 4 hours.
9.   Raw and treated effluent is to be analyzed periodically for pH, TSS, BOD and O&G. .

10.Skilled Operator will be required  to carry out all these instructions.

11.The operator will maintain a log book. And chemical stock registers.


12. The performance of the ETP is dependent on the proper skill of the operator and proper chemical dosing.

Polishing pond for Magur fish in ETP treated water.



 Oxygen level in the tanks should exceed 3 mg/l. If the magur fish tanks are supplied with turbid water it is advisable to filter it with through a sand filter and to aerate the tanks at night for maintaining oxygen level by using an air blower The aeration grid should be one feet above the bottom of the tank so that mud can settle at the bottom..Magur requires mud. .
A tank containing such a fish group required approximately 5 liter/min water supply. Depth of fish tanks should be 0.5–0.75 m. Let us take water depth 0.75 meter.The freeboard of the tank should be 0.5 meter so that fish don’t jump out. So total depth of tank is 1.25 Meter. Volume of the tank should be 10,000 liter. Normally it should be square in size. So length and width of tank will be 4 Meter by 4 meter. 
For avoiding the direct contact between tank wall and fish it is better to cover the inner surface of tank with polyethylene sheet.
Inlet water should be sprayed in the tank from a perforated PVC tube throughout the length.
Outlet water will overflow from a overflow weir at the outlet side. The top of the overflow weir will be covered by net/mesh. The proper mesh size is 1.0–1.5 mm
Most efficient way of plankton maintenance is frequent manuring with small doses of poultry or cattle manure. In addition to plankton maintenance, frequent manuring maintains an active and effective bacterial population in pond water. It facilitates decomposition of metabolites hampering fish growth. Poultry (5–15 kg/bigha) or cattle (10–20 kg/bigha) manure is sufficient for frequent treatment of pond.
Daily brushing of wall and bottom of the tanks is essential. Moreover, when there is deterioration in water quality, 10–20 % fresh water replacement is suggested.
Lime is used for killing different living organisms remaining in muddy pools after dewatering of ponds.
IF MAGUR SURVIVES IN THE POLISHING TANK, IT MEANS THE ETP IS RUNNING PROPERLY.


TANK SIZE : 4 x 4 x 1.25 Meter. Water depth = 0.75 Meter. Free Board=0.5 M
