INIDA: São Domingos


Nora, who works with INIDA's site at São Domingos, was able to give us a tour and talk with us about general agriculture activities. She first took us to the "Estufas" which are tent-like, net structures they use to block insects, wind and dirt from their engineered "pretty" cucumbers. The tent themselves weren't in the best condition, with lots of holes in the material, but the plants seemed to be doing quite well. They produce these engineered plants in order to sell the seeds to farmers and the workers also have several non-tent experiments with tomatoes, potatoes, squash and pepper. There are all types of fruit (banana, mango, papaya, pilmebi, picanga, strawberry, etc) and INIDA is testing other plants like macadamia nut and eggplant in hopes of introducing them. (On a somewhat unrelated note, because of all these varieties of food, they have a problem with people stealing their food, ruining their experiments' results - and sometimes have to place paper bags around, for example, their mangos to deter theft.)

I noticed one experiment that tests different levels of drip irrigation and think the data from that would benefit the INIDA paper. However, she did note that they are no official irrigation technicians and the one person who works with their system may be out of practice. Nora also gave us the names of the two commercial sellers of irrigation systems: Agroproducto (in Sao Fillipe) and Agrocentro (in Fazenda). Regardless, INIDA does do outreach and demonstration plots: for example, they help the farmers measure the correct amount of water for their crops so they don't flood them.

Nora also helped us improve our agro-vocabulary, by pointing out issues with soil bacteria and crop rotation as well as pesticide and fertilizer. Additionally, I learned there is a finance problem as farmers fail to budget out money to maintain their drip irrigation systems and once they break, they result back to traditional, open-pipe canals (which are mega inefficient).

After our tour, we regrouped with a plan for the week and decided to go visit at least one of the commercial sellers on our way to Praia: Agrocentro. The staff were nice and tried to answer our questions as best as possible. We discovered that:
  • A drip irrigation kit for 500 sqft costs 18500,00 CVE - and has enough tubing to be divided into 2 fields already. Additional tubing is extra
  • T-tape tubing costs 24,000 CVE for 2500m; 8000 CVE for 1000m; and 5580 CVE for 500m.
  • There is "incorporated watering" and drip holes can range from 20 to 33cm apart.
  • They carry three brands: Pathfinder, T-Tape, and Tubo Pe 16 el gota jeador(?)
It is also important to note that small farms will have different purchases from large farms. I sent a follow-up email to ask for data on sales but have yet to get any reply.

Women of Color in Graduate School

Image
Recently, I've been asked (by a few people) how it feels to go through graduate school as a woman of color. And, to be completely honest, it's incredibly exciting and exhausting all at the same time. Being a woman of color -- specifically a black woman, particularly in STEM -- has a lot of challenges. If you simply search the phrase "black in graduate school," you will get statistics that are very humbling; articles and think-pieces on how different the Black or person-of-color experience is from students who are not minorities; and other outlets detailing how little support many Black and non-Black students of color feel that they have. In fact, the Council on Graduate Schools recently reported that, in 2017, Black students made up just 11.9% of all first-time graduate students in the United States. (That said, 68% of them were women! So, we are making p r o g r e s s.) I'm not sure what the numbers are at Boston University, but it doesn't seem that far o...

Truss Design (Final)

Image
We finally made it to the end! After the preliminary design report, it was time to finalize our actual design (since we were given enough materials to make one truss to test). After doing a few more draft sketches and analysis, I was able to pick up on patterns on which types of designs produced the maximum strength (all within the parameters we were given). Finally, I came up with the sketch at the bottom-right, and the MATLAB analysis produced the highest load we were able to reach. We theorized that: two members would buckle first instead of just one (Members 3 and 4); the maximum load is 11.62 ± 0.063N; and the total cost of the truss is $290 (under the budget limit). From there, we moved to prototyping: we cut the straws as close as possible to the lengths specified in our final design. To create uniform gusset plates, our "joints," we used the circular cap of an individual Tropicana Orange Juice bottle. It met the area requirements and acted as a stamp...

Hackathon: TechTogether Boston

Image
iOS app Last weekend, I had the wonderful opportunity to participate in Boston's largest all-female and non-binary hackathon! A group of friends and I wanted to digest as much tech and nerd information as possible, and we basically made it our mission to go to nearly every workshop session offered for two days straight. I don't know how we managed this but we did. From 5p on Friday and all day on Saturday, it seemed I bounced from one room to the next with a nap here and there. There was a workshop on rapid prototyping with AdobeXD -- which I am in love with. Then, I was able to create my first phone application during a workshop on iOS app development with Swift  (it's much easier than I had imagined), followed by a workshop at 2am on Android app developmen t. For my very first hackathon-conference, I wanted to focus on skill development and learning, rather than the competition. However, seeing everyone so wrapped up in their individual designs and programming ...
