What is UHP/HHP?
High hydrostatic pressure
A lot of force is put on one point., over 75 MPa
Why does UHP/HHP work?
How does the inactivation by HHP go over time and aw-value?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
At what pressures do spores become inactivated?
What is the effect of HHP on inactivation of spores?
Copnclusion spores can survive high pressure treatment
What is (PEF) processing?
The membrane of the microorganism breaks because:
20-60 kV/cm goes trough it.
The balance between + outside the cell and - inside the cell is disturbed and therefore holes are present in the cells. Therefore there is a dis-balance of compounds in and outside the cell and it will die.
However you do need a wet product like dairy, soup, sauces, fruit juices.
How is the effectivety of PEF processing influanced?
The higher the pH the better the inactivation by PEF.
What is the lytic cycle of a virus?
The virus enters the cell. Starts replicating itself and and advantualy the cell will burst open and the virus will be spread.
What is the lytogenic cycle of a virus?
The DNA of the virus is build in the DNA of the micro-organism and also replicates when the cell is replicating. At a certain point one replication will due to a certain factor extreete the virus its DNA and now it can work as the same as the lytic cycle.
What is the holin-lysin module?
The holin makes a hole in the membrane.
The lysin goes trough the holin and will break the cell wall.
Because there are a lot of components in the cell wall there are a lot of different lysins.
What are the two functional domains of a lysin?
The other part is the catalytic domain: this will give the activity to the lysin. So this catalyses the break down of the cell wall.
Why do you usually need a mix of baterio phages?
What can you do if people don't want to add bactero phages.
What can influance the activity of lysins?
How can fermentation improve food safety?
Or there is competition and the fermenting organism wins form the pathogen.
But most important antimicrobial peptides.
What are antimicrobial peptides?
The producing micro-organism has an immunity mechanism for this peptide.
Very effective since it can work in the nM range.
What is the disadvantage of antimicrobial peptides?
Why does antimicrobial peptides only work on grampositive bacteria?
What does a hurdle technique mean?
Hurdle technology deliberately combines existing and new preservation techniques to establish a series of preservative factors (hurdles) that the microorganisms in question are unable to overcome (jump over). These hurdles may be temperature, water activity, acidity, redox potential, preservatives, and others.
