Hi,

I have a question wth Action in Enumlist field

I want to add data in a Enumlist field with the Action function.

The problem is that every time I use the Action function, the field is updated with the new entry. I want to add a new entry without loosing the data that is already in the Enumlist field.

What could I do?

Thanks

Hi, to the community

I have a problem with one of my apps

I have a table ERGO with gardens from our customers.

I have another table FIVA with the scheduled maintenance visits from group of our gardeners. Of course I have a date column. In this table I have a reference column "Related FIVAs [ERGO]". It shows the scheduled maintenance visits for the gardens of the ERGO table.

My problem is that I want to find the gardens (of the ERGO table) which are not scheduled in the FIVA table by Month. I don't want to forget a maintenance of any of the gardens.

What could I do?

Hi, members

I have another question about expressions.

I have a table with 2 fields for prices.
[HS]: field with a fixed price for High Season (Months: 1,2,3,4,5,6).
[LS]: field with a fixed price for Low Season (Months: 7,8,9,10,11,12)

I have also a field [MONTH]

I want to create a virtual column.
In this column I want to take the price from [HS] only if the field [MONTH] is 1,2,3,4,5,6 and the price [LS] if the [MONTH] is 7,8,9,10,11,12.

What is the correct Syntax for the App formula? I suppose that is a combination with IF and OR, AND expressions but I am confused.

Is there a friend to help me?

Hi,

I have a problem.

In one of my tables I have a field by type "duration".
When I want in UX to see the amount of the duration by GroupAggregate, the choice "duration" doesn't exist. I see the choice "price" because I have another field with this type.

Why I couldn't aggregrate Duration?

Hi

"Actions" is very useful but I want to know if I could use an expression to the field 'To this value" that it would be a variable or a list.

For example: I want to make an evaluation using one of the numbers 1,2,3,4,5. Is it possible to have one only "action" that it could show me the list of these numbers and I would choose one of them for the column value?

Thanks

Hi to all members

I have one problem and I would like some help.

I have one table CUSTOMERS with a unique ID

I have another table "1st meeting". In this table I record meetings with customers from the first table
If they want a second meeting I have a field (Y/N) in the "1st meeting" table and another field for a future meeting date.

I have a another table "2nd meeting". In this table I have meetings with customers from "1st meeting" table who they asked for a 2nd meeting.

My question is:

I want to have a filter table (I suppose a slice). In this I want to see customers from "1st meeting" (with "Υ" in the field for the future 2nd meeting) that they aren't in the "2nd meeting"

Hi,

I have a column in the form of Datetime.

I want to create a virtual column in the form of Date to show only the date of the Datetime Column.

My questions are:
How I could do this?
How could I group data in the menu of the app grouping data per date?

Have a great weekend
Thanks

Play of Color: Imagine a gem so iridescently beautiful that a phrase, play of color , is coined just to describe it. How does an ordinary sludge of sand and water, boringly described as hydrated silicon dioxide (SiO2. nH2O), express every color in the spectrum of light?

Precious opal is formed when a solution of silica seeps through cracks in a rock very slowly : at a rate of one centimetre thickness every five million years. Under pressure, spheres of silica 150-300 nanometers wide, deposit in crystalline arrays. This regular packing, spaced close enough to the wavelength of light, has the effect of a diffraction grating, and the scattered light can be described by Bragg's Law. Nearly all the earth's supply of precious opal comes from Australia, formed in the Cretaceous period, more than a hundred million years ago.

Eric the Pliosaur: Now imagine a massive thick necked beast that once cruised through the Late Jurassic oceans, with a jaw four times stronger than T. rex and 10 times more powerful than any living creature. 150 million years later, our pliosaur has been "opalized" to an iridescent sheen, his fragments discovered by a lucky miner in Australia's Coober Pedy and sold for $250,000 USD to a wealthy businessman who subsequently lost his fortune.  Christened Eric the Pliosaur by a mischievous archaeologist who was asked to put the bones together, after Monty Python's Eric the Half a Bee, the fossil turned out to have a fish inside its belly, fittingly named Wanda. After a public campaign, Eric was eventually purchased for display by the Australian Museum.  What a thrilling journey for Eric. 

► Musical accompaniment: Monty Python - Eric the Half-a-Bee (1972)  

Half a bee, philosophically, must ipso facto half not be .
But half the bee has got to be, vis-à-vis its entity - d'you see?
But can a bee be said to be or not to be an entire bee
when half the bee is not a bee, due to some ancient injury?

Hybrid Heart

Via +ScienceSunday

Stem Cells Grow Beating Heart

● Heart Beats Again
"A newly beating heart is part-mouse, part-human. For the first time, a mouse heart has been made to pulse again by stripping it of its own cells and rebuilding it with human ones (see video above)."

"To create the hybrid heart, Lei Yang at the University of Pittsburgh and colleagues took the heart from a mouse and, in a process that lasted 10 hours, removed all its cells. The remaining protein scaffold was then repopulated with human heart precursor cells – stem cells that had differentiated into the three types of cell required for a heart. After a few weeks, the organ started to beat again. "Our engineered hearts contain about 70 per cent human heart precursor cells, which provide enough mechanical force for contraction," says Yang."

Mouse heart uses human cells to beat again

Researchers Use Video Game Tech to Steer Roaches on Autopilot

North Carolina State University researchers are using video game technology to remotely control cockroaches on autopilot, with a computer steering the cockroach through a controlled environment. The researchers are using the technology to track how roaches respond to the remote control, with the goal of developing ways that roaches on autopilot can be used to map dynamic environments – such as collapsed buildings.

Data Rock

In modern astronomy, large catalogs of data are vital to our understanding of the universe.  But just what does it take to create these large catalogs? +Scott Manley  has a great video of one example, discovering and cataloging the asteroids in our solar system.  It tracks asteroid discoveries from 1980 to the present.  

We now have almost 600,000 asteroids in the catalog (http://goo.gl/dsyPV) which includes not only their location, but also the size and shape of their orbits.  If you want to track which asteroids might hit Earth, this is the catalog you need.  If you want to mine asteroids for rare Earth metals, this catalog will come in handy.

As you can see, this is a decades old and on-going effort.  It draws upon amateurs and professionals, ground-based and space-based observations.  This is what modern astronomy looks like.  It’s only byworking to... more »

Fluorescent Coral

Via +ScienceSunday 

A fluorescing  maze coral under high magnification. 

When we see corals, even closely, most of the details escape our attention. Besides, the other element that can easily be missed is fluorescence.

Corals have lots of fluorescent pigments for various reasons, including the necessity to "shield" the symbiotic organisms from excess of light (or just deliver the light of a more useful spectrum). Fluorescence gives them wonderful colors that are absent on photographs taken with regular light flashes but remain when you use light as close to natural as possible.

Ferrofluid - The Magnetic Liquid!

Materials scientist and Christmas Lecturer Mark Miodownik demonstrates some of the 8weird properties of ferrofluid8. This liquid is literally 'dripping with magnetism', containing a suspension of ferromagnetic nanoparticles that make the liquid responsive to external magnetic fields, generating unusual patterns, shapes and motion.
