Undergraduate Research - Science topic

My final year undergraduate research is "Extraction and yield optimization of essential oil from clove." In this, I am currently using clove bud to extract clove essential oil. The extraction method is currently using the hydro distillation method. In this, I soaked the clove bud powder in deionized water and used no other chemicals. When the oil mixture extracted from it, that is, the distillate, is left for a while or overnight, the two layers do not separate like normal oil; the oil also comes out as droplets in the water. I saw a reference that said that diethyl ether is used to separate the oil layer from the water. Then the ether layer is separated because it contains the oil. Then the separated sample is heated to remove the diethyl ether and separate the pure oil sample. Because the boiling point of diethyl ether is 34 degrees Celsius. I also tried it that way. However, since diethyl ether is a toxic compound, clove oil should be human-friendly and not harmful to health when we use clove oil for any application. We are doing this in a university lab, so we don't have advanced instruments or many chemicals. So please give me a good idea for this. Is there a good replacement for diethyl ether or the best way to do this?

Hello guys I am currently doing our undergraduate thesis and the design that we have in our study is multiple regression with a title of "A MULTIPLE REGRESSION ANALYSIS BETWEEN THE LEADERSHIP SKILLS AND ACADEMIC BURNOUT AMONG COLLEGE STUDENT LEADERS" our participants are the organizational officers from our school, the problem is our panel only require us to find an article or study that uses non probability sampling and pearson r correlation at the same time.

as a my undergraduates research, i have an idea about develop anti bacterial coating using chitosan and aloe Vera gel. So, after develop coating it should be apply on external surface of surgical tape. The main reason is reduce the bacterial contamination around the wound sometimes because of bacterial infections wound can be increased and difficult to cure. Also i think apply biodegradable adhesive agent to composite bind on external surface of surgical tape. Can i know what are the can be used biodegradable adhesive agent and any suggestions for my research topic....?

Does anyone have any idea where I can find Consumptive Behavior focuses on lifestyle Measurement fully with the blue print, indicator, etc for me to finish my dissertation undergraduate, with the title The Impact of Fear of Missing Out and Consumptive Behavior on Generation Z's Lifestyle.

I think, for a long time, there has been a tendency for journals to favour work from more established researchers or institutions, thus potentially overlooking quality undergraduate research. This bias might have made it more challenging for Bachelor's degree theses to gain acceptance in academic journals.

if yes, is the publication free of charge

Bachelor's thesis - Fabric Composition Recognition Using Convolutional Neural Networks: A Deep Learning Approach for Textile Analysis

Hi everyone,

I'm doing my undergraduate research related to fabric composition identification using CNN. I'm looking for a pre-trained model to use in my research. Where can I find such a model?

Also, I'm interested in finding datasets that correspond to my topic, if you can help

I am interested in using a scale that I found on ResearchGate in my undergraduate research.

I'm a student with an engineering background, and I'm looking to familiarize myself with Zemax and ANSYS for my undergraduate research project, which is my final year project. Could anyone provide guidance on where I can find resources to learn this software effectively and improve my skills in optical system design? I'd appreciate fair suggestions, as I'm new to optics and Zemax.

Hi,

I am carrying out a very basic undergraduate research study with no stats teaching on the course (medical degree) as a result I am floundering and wonder if anyone could help.

I am using two pre-validated Likert scales looking at the relationship of Emotional Intelligence and Resilience I have put this into a scatterplot in Excel to which it looks like a positively significant result (graph attached) My Pearson's correlation coefficient between the two is coming out at 0.797 would that be r=0.79? and from what I read this is significantly significant?

However when I attempt to work out the P-value it shows as 3.419 which is not.

Any assistance or thoughts on what I am doing wrong would be of great help.

Many Thanks :)

An MBBS student of mine has worked very well on a non-funded research project that has reached the stage of paper writing. I want to decide on the journal so that the manuscript can be tailored to its guidelines.

I am unable to find any such journals on MedLine/ Pubmed / PMC except those pertaining to medical education/pedagogy.

I would appreciate suggestions of indexed journals with nominal APCs which are receptive to undergraduate medical research papers.

Otherwise, I will have to submit it to a usual journal where it will need to jostle around with papers coming in from more significant funded projects.

Thank you so much!

As a starting topic for undergraduate research

In my undergraduate research, i am planning to investigate effective pore size and the effect of sound absorption in directional pores in ceramic material. So I am planning to obtain a porous ceramic sample with a diameter of 5 cm with 1 cm thickness. what should be stating pore size if they are in cylindrical type

I am doing an undergrad thesis right now, and my study is about knowledge, attitude, and perception toward HIV/AIDS. The problem is most of the studies I found measure knowledge using 3-point scale (e.g., YES, NO, and I DON'T KNOW) but my school requires a 5-point scale and I can't find any research instrument. Is it possible to find a correlation between knowledge and attitude even though they have different scaling method. Also, if you know a study that measures knowledge on HIV using 5 point likert scale please share the study or the link. That would be a big help for me. Thank you.

Hi.

G'day,

I've tried several different settings to find a optimal scheme for 3D VIV simulations. Basicly, I'll keep using PISO since it's highly recommended for transient flow. (and with Green-Gauss Node Based gradient). But what about pressure interpolation(PRESTO!, body force weighted) and under-relaxation factors for pressure and momentum? I tried both pressure interpolation schemes, but didn't benefit from them as the pic shows:

Although the user guide says that it's recommended to increase under-relaxation factors for all equations near 1 when using PISO, it seems to be too aggressive?

Does anyone know how to make the calculation stable? Please share with me. Thank you!

Note that my mesh was built well with minimum orthogonal quality of 0.3, and dynamic mesh was set correctly.

Abaqus can be used to calibrate material data. To do this, you need experimental data and a simulation of the experimental set-up. Experimental and simulated results are then compared to determine how good the fit is. If the fit is not satisfying, the material properties are modified and the simulation is rerun, trying to obtain a better fit. This can be done manually, but it is labour intensive. So I am trying to automate this optimisation in Python for my summer undergraduate research project.

The attached file is the logic flow chart showing the summary of needs to be done.

I am trying to compare simulated data to experimental data and match them by adjusting Johnson-Cook material parameters (A, B, C, n , m).

So far I have been using GEKKO optimisation module in Python. The Python file is also attached to this question. Last time, the code worked for a stress-strain data for another material and the problem was in units of data.

Currently, I am using force-displacement data which is stored in the attached .txt files (force_2 and displ_02). The attached image is the result of running the code.

Could anyone help me to find a problem in either my logic or my code,please? Is the problem in values of parameters and force-displacement data?

I have a undergraduate research study. For that I need a explanation about this question

Dear Colleagues,

Wishing you a new year and hope you are well and in good health.

I am currently reaching out to you in need of some advice on stolen academic publication. my oirginal work has been submitted by someone else and how to resolve the matter.

I have submitted a research article for publication on Emerald, however, the journal editors have informed that the article stolen (already submitted by another person for undergraduate research).  I have researched out to the particular university where the research has been subject to been published and they have requested me to send the Turnitin report.

Can you please advice on the matter to how to resolve this.

I am conducting some undergraduate research on people's preferred reading device (paper, tablet, kindle, etc.). I want to see how various likert scale measures differ with age, gender, and preferred reading device. Would an ANOVA be the best method to use? I saw on other posts that a Mann-Whitney may be better due to an ANOVAs assumptions on the data being normally distributed.

I am carrying out my undergraduate research study and I am yet to get the needed number of participants. I know I can easily wing it but I need accurate responses and clear data. All the mediums I have used have given some participants but I need more, like 50 more. So can anyone suggest sites or other mediums aside from social media and posters, that I can use to recruit my participants?

It is extremely hard to get on board of international science (by that I mean enter an abroad university, and visit international conferences) when you are from a developing country and at the start of a research career. You need an impressive CV to get funding, so I wonder if someone can share information about contests for undergraduates or/and Master students of Life Science.

From my side, there is International Student Tournament (https://www.facebook.com/intscitour/), iGEM (https://igem.org/) ... and that`s basically it.

Thank you

Respected researcher,

I need your help: What are the molar extinction coefficient and blank absorbance values for Hydrogen Peroxide solution (10mM) at 440 nm? Could you also kindly elaborate on the procedure which is required to determine the same?

Sincerely thank you from a budding undergraduate research aspirant!

2 undergraduate researchers were tasked with doing data collection for a paper that was recently published. The data collection took months to complete. However, in the paper, there is no mention or acknowledgement of their names as the ones who collected the data.

There is a “Data Availability“ section that says that the data can be obtained by other researchers now using the same method and that the data set and analysis can be obtained via the undergraduate researchers’s professor (who is also first author). There is also an “Acknowledgements” section that says the undergraduate researchers’s professor/first author was funded by the university for completing the research (Yes, the undergraduate researchers were also granted a small amount).

Should the 2 undergraduate researchers be acknowledged in the paper for doing the data collection that was used for the paper?

I am interested in research and I want to learn more about research, and I think the best way to learn more and add experience is to become a research assistant. Right? or Nahh?

I'm doing a research in Marketing

Hi everyone, I'm currently doing my undergraduate research. I work parttime at an event company, and one problem that I notice was the registration process on the current event platform is too complicated. Therefore my research goal is to simplify it, and I want to do that by implementing a different platform for the process. Any ideas which method/approach I should use in order to test the new platform compared to the previous ones?

I am currently performing undergraduate research in forensics and I am comparing two types of width measurements (the widths of land and groove impressions on fired bullets), one taken by an automated system and the other performed by my associate manually using a comparison microscope. We are trying to see if the automated method is a more suitable replacement for the manual method. We were recommended to perform a simple linear regression (ordinary least squares) however when it comes to actually interpreting the results we had some slight trouble.

According to pg 218 of Howard Seltmann's experimental design and analysis, "sometimes it is reasonable to choose a different null hypothesis for β1. For example, if x is some gold standard for a particular measurement, i.e., a best-quality measurement often involving great expense, and y is some cheaper substitute, then the obvious null hypothesis is β1 = 1 with alternative β1 ≠ 1. For example, if x is percent body fat measured using the cumbersome whole body immersion method, and Y is percent body fat measured using a formula based on a couple of skin fold thickness measurements, then we expect either a slope of 1, indicating equivalence of measurements (on average) or we expect a different slope". In comparison to normal linear regression where β1 = 0 is usually tested, I was just wondering how you actually test the hypothesis proposed by Seltmann: do we test it the same way you would test the hypotheses of a normal linear regression (finding T test values, p values, etc)? Or is there a different approach?

I am also open to suggestions as to what other tests could be performed

A quick thank you in advance for those who take the time to help!

Hey , I'm currently doing undergraduate research and checking the applicability of Remote Sensing images to obtain soil salinity over paddy areas? I derived few soil salinity indexes using few methods such as NDSI etc.

Now I wanted to know the general soil salinity index range (ex NDVI = -1~+1) to check my output is correct or not...

because,

I used Landsat 8 Level 1 it gives - 0.01 ~ 1. 49

(after apply TOA + Sun angle correction)

and

when used Landsat 8 Level 2 it gives - 1126 ~ 427115

(directly)

Or anything related with shielding materials and dosimetry for medical application. I need topics that can be researched on and suitable for undergraduate research work.

Thank you.

Greetings

One of the most major problems of writing an undergraduate article is the lack of access to a laboratory and a professor to check the accuracy of article information in the laboratory.

For example, at my university, only postgraduate, PhD and postdoctoral students are allowed to work in the laboratory. What should an undergraduate student do if he or she wants to write an article and extract the information needed for his or her paper from the lab?

Undergraduate students do not have access to professors and laboratories to verify their ideas, what should they do to write an article?

Can he write another type of article that is published in a valid journal but does not require laboratory information? Or can he collaborate with a foreign professor to write an article?

What is the solution to the problem?

Hello everyone!

In the Fall, I am curating an undergraduate research experience laboratory, and I am going to induce some restraint stress on 150 gr SD rats. The restraint tubes are quite expensive on their own, and I will need about 16... has anyone had any luck with cheaper (even DIY) alternatives?

Thank you all so much!

Hi, I'm an undergraduate research student working in the labs this summer, and my mentor and I are stumped. We work with an MG16-55 strain E. coli, and up until recently, our optical density measurements were tracking consistently over a 5-7 hour growth curve. We had two runs with significantly higher readings and hypothesized the media temperature or an unknown contaminent caused the higher reads. Uncultured media grew nothing in our incubator though, and our temperature-controlled stored media is tracking data from last fall when the lab was cooler instead of the runs from this summer when it is warmer. Does anyone have any idea what else we should be looking for?

We are investigating the impact of online learning environment on sustained attention and student engagement among undergraduate students (Year 1-3).

We had the participants watch a lecture video and answer multiple choice questions related to the content of the video. We also had them fill an engagement questionnaire which had questions about their involvement with peers and various university related activities.

Hypothesis I - 1st year students are able to focus more over a long period of time than 2nd and 3rd year students.

Hypothesis II - 1st year students actively participate and are more engaged with peers than 2nd and 3rd year students.

My questions are:

1. What statistical test would be most appropriate?

2. How do I set a value to prove significance...for example they had 13 MCQ questions, how do I know what number of questions they need to have answered correctly in order to say they paid more attention?

I'm very lost, i'd appreciate your help and any remarks that could provide me some clarity.

We are currently conducting our undergraduate research proposal about the impact of monetary and fiscal policy on the economic growth of the Philippines. We used real GDP as a measure of econ growth. Our problem is that for our theoretical framework, we adopted the monetarism and keynesian theory as based on the empirical studies we reviewed. However quantity theory of money talked about how it influences nominal income. Though it has an effect on real income but only short-run. During our consultation our professor said it might be difficult to use QTM as a framework for our study. Is there any way we can still use it or what are other theory that can be used as framework in terms of the effect of montery policy on the econ growth of a country? (We've sorted things out on the side of fiscal policy though). We are very new in this field and don't have adequate knowledge with regards to this yet (don't know though why we conducted this study lol). Thankyou in advance.

Hello all,

I was wondering if I am in danger of crashing out my protein of interest (native fliC) under these conditions:

first, I solubilized E. coli cell lysate pellet with 8M urea + 200mM acetic acid. pH 4. I subjected the soluble fraction to 14% PEG3350 precipitation. Next step in the schematic is to perform 2-phase separation using TritonX-114 and PEG3350. But before I performed 2--phase, I dialyzed my protein sample (after PEG) in 20mM Tris, pH 8.0 (buffer that I will use to equilibrate my anion exchange resin-- after 2-phase).

Was this a smart thing to do? Or am I in danger of precipitating out my proteins with such abrupt buffer change? I have read in Methods in Enzymology by Dr. Burgess that denatured proteins at 8M Urea need to be dialyzed step-wise in decreasing molarity of urea to avoid misfolding..

Best,

Hello.

I am attempting to draft a model for producing social and affordable housing units in Ireland based on the model used in Vienna. The methodology I have decided to employ is mixed-use. The qualitative data will be collected via interviews with industry professionals and policy experts. My aim is to apply the information collected here to a hypothetical example in which the effect on cost of implementing the model can be measured.

My question is what is the proper name of this type of quantitative research and is it acceptable to carry out as part of an undergraduate research project? Thus far I have been referring to it as a hypothetical/theoretical case study. However, I am wondering if this type of research is more in line with an experiment or another type of research.

Obviously it is important to use correct titles when carrying out research and I would like to ensure that I am doing this. Any answers or recommendations are welcome.

Thanks.

I am conducting an undergraduate research project and I am unable to complete the calculations prior to the experiment.

I am a member of undergraduate research anticipating to investigate the protein expression of fungal biofilm after teatment of shockwaves and amphotericin B. After growing biofilm and containing its extracellular matrix in Tris-HCl buffer, a series of treatments, vortexing, ultrasonication, treatment with cation/anion exchange resins, centrifuging, and filtering with millipore membrane will result in supernatant that contains proteins, triglycerides, and carbohydrates. Unfortunately, we are unsure how to isolate proteins from the supernatant containing other organic compounds. Any feedback on how we can successfully isolate pure ECM proteins from the supernatant will be greatly appreciated.

In addition, if there are other successful protocols for extracting and isolating proteins from fungal biofilm ECM, it will also be very much appreciated.

I am working on an undergraduate research team where we are working on synthesizing liposomes. We have looked at various protocols and were wondering if anyone has any information or advice on how to quantify the molarity of liposomes to PBS after filtration when synthesizing liposomes.

When it comes to the filtration of liposomes during their synthesis, which methods exist and which are feasible for an undergraduate research project where we are trying to synthesize 200 nm diameter liposomes?

To be clear: I'm asking about pen/strep to prevent contamination, NOT selective antibiotics. Should I add the antibiotics when I am making the media? Or should I add the antibiotics directly to the flask whenever changing the media.

Note: I understand using antibiotics like this is less than ideal, but I run an undergraduate research lab so I feel the extra level of precaution is warranted.

I did a computational chemistry research regarding molecular docking and molecular dynamics. I scored well in that research. However, I am desired to be a physical chemist, majoring the field of chemical thermodynamics. Due to lack of facilities and experts in my college I could not do a research on this area. I am willing to go abroad and do a PhD in physical chemistry. Will my undergraduate research be a problem in that case? What is your advise about publishing my undergraduate research?

Thanks in advance.
