Hi, I'm searching for studies on the diet of the mayfly Ephemera vulgata (Linnaeus 1758)? From a European database (freshwaterecology.info), its feeding type preferences is given as 20% gatherer (FPOM sediment) and 80% active filter feeder (FPOM, CPOM and micro prey from the water column). The reference for this information is given as the AQEM expert consortium. I would be really interested to see the original study providing this information, or any other studies that explores food item preferences (e.g. gut content) of E. vulgata. If you know about any papers, thesis, reports etc. with such information, even anectodical, I would be grateful if you could share this information with me.

what can be added and in what concentration to make a 10% fat feed into 30-40% fat feed. I read about Kreamolene but its not available in my country. canola oil and milk powder was also suggested but I am unsure on how to add it to the existing feed which will also be palatable for the rats. Any advice or suggestion will be appreciated

Hello every one am writing my Msc research proposal.
My experiment will test three feed sources (pulses) as a bee feed supplement. The trials will be set out "Completely Randomized Design. Each treatment group of bees will be provided with 150 g of the respective treatment diets. The DATA data to be collected will be amount of food consumed, sealed brood and bee bread areas and bee strength and honey yield. Data will be subjected to ANOVA using SPSS software (version 28) with proc mixed model of SAS, and Mean values will be separated using to Duncan’s multiple range test (DMRT) at p =0.05 (SAS Institute, 2012).
Is there anyone who advised me whether my data analysis methods are appropriate or not.

Important things NOT to doin the management of SAM cases is "Don't give iron during initial feeding (Stabilization ) phase. Iron can be given only after the child has been on F-100 for 2 days (usually during week 2). So why it is not given during early (stabilization) phase of the management for SAM cases?
Traditionally, doctors would wait for post operative ileus to resolve as evidenced by passage of flatus or stool in order for them to initiate feeding. Current evidence shows that early feeding is safe and improves outcome. The enhanced recovery after surgery protocols have early feeding as one of the elements that improve outcome. In practice however, some doctors will instruct that nothing should be given by mouth till ileus resolves mainly following bowel surgery in low income countries. What is the reason for this? What can be done to move from tradition to evidence based practice in this area?
I am a beginner. I have designed a printed monopole antenna in CST. Multiple resonant peaks are coming but not broadband. It's most probably that the antenna is not matched. I need the relation between feed width and reflection coefficient or vswr.
Hi
I am trying to find technique to improve isolation between ports of a multiple feed slot ring antenna.
Generally there are dual feed which are orthogonal and the port isolation between them is well below -30 dB.
I tried to make annular slot ring antenna with slant polarization and also vertical or horizontal polarization. However the non orthogonal feeds have port isolation below -10dB.
O would really apprecitate if anyone can comment on suitable technique usuagea in this scenerio to put myself in right direction.
Thank you

I want to learn and include the temporal relationship alongside my variables at each time series instance.
And I learnt that previously they used models to represent all variables by a single variable or reduce the dimensionality of variables.
I read also they created a variable for time indexing which include first difference values of time, ex. for first instance its T2-T1, and i want to know more techniques to include temporal relationship as a variable or by any means before feeding my dataset to clustering algorithms. Do you know any other techniques to represent this as a feature or by transforming existing feature to include temporal/spatial pattering , or what they call it inter/intra patterns?
can anyone help me in understanding that how do we simulate feed rate and spindle rotation in abaqus during incremental sheet forming?

Reject percentage is the percent of reject flowrate allowed to leave RO or UF membranes,
Reject % = reject flowrate/ feed flowrate x 100% = (feed flowrate - permeate flowrate)/feed flowrate x 100%
By controlling the reject valve, the pressure difference can be controlled to prevent damage to RO/UF membranes.
Hello Everyone,
I would like to calculate feed flow velocity or feed flow mass flow rate based on the given data, for a heterogeneous chemical reaction taken place inside a reactor. I have temperature, pressure, ratio of A/B (species)=1, GHSV (gas hour space velocity)=3000hr-1, (d) dia of pipe=4mm and (L) length of pipe is 0.5m. (Catalyst is filled in the whole pipe)
Reaction (A+B <--> C+D)
I tried to calculate based on the GHSV formula =Volumetric flow rate/ Catalyst volume or packed bed volume;
I calculated the volume by Ac*L. But the velocity, which I am getting with this formula is giving me totally different results. (Ac=pi/4 *d^2)
Can anyone correct me and help me with that?
Thanks in advance.
I have collected intraspecies interaction between adult, subadult and juvenile of vulture during their feeding. But I have only noted the frequency of interactions not their types. I am confused with the analysis now!! What test/analysis can be done with the data??
Out of the 7.7 billion world population in 2020, more than 800 million people were undernourished, and more than 50 million were suffering from urgent food hunger. Over the next three decades, the world population is expected to grow by 25%, which mandates the need to adopt novel strategies to feed the world. From your point of view, what individual actions and/or novel research work may provide a solution to the aforementioned worldwide challenge?

Dear All, I am working on drilling simulation using Ansys. But I am not able to provide angular velocity and feed using software. In initial conditions I provided angular velocity but my tool is not rotating. Please help me.
I am using CST software(Computer Simulation Technology) and I need to know the incident power density on antenna surface . I have applied a 0.5 W (as it is the default value in SAR calculation) into the feeding port to calculate SAR(Specific Absorption Rate), but the value of SAR gets high .
So, please let me know how can I check the power density in CST for my designed antenna?
I am using spwm and i am not using a low pass filter at the output, so my output consists of multiple harmonics. I am thinking of reducing the voltage to 115V rms(of the complete output not just the fundamental component) by reducing the duty cycle of the pulses. I am able to achieve voltage close to 115V rms in this way. But everyone else is suggesting to use a dc-dc converter first to reduce the input dc voltage and then feed it to the inverter. Why my solution is not good and is it compulsory to use a dc-dc converter first in this situation?

I have quite a few mean results so how do I conduct regression?
I have done a correlation for all the means but then should I do a regression and if so how do I do it for all the means? Thank you in advance.
The tertiary treatment in our effluent treatment plant consist of MBBR followed by activated sludge process. The efficiency of removal is determined by reduction in COD so in our current operating conditions we are not achieving the required COD reduction i.e compared to same feed COD. So what are the possibilities of improving this treatment.
Current arrangement : Equilization - MBBR - Aeration - Clarifier.
Feed COD - 2500ppm, Treated water COD - 1400.
Design COD reduction - 80 - 90%
Design feed COD < 4000 ppn

Thank you
In the circular monopole antenna with partial ground plane is there to make it ultra wide band or match the impedance of circular patch?
Please clear this confusion for me? Because, usually, we do inset feed to match the impedance. here we are not doing inset feed but edge feed. so, the purpose of partial ground plane is just to increase the bandwidth of antenna or to match the impedance as well?

I need know how to assign c-p values to my nematodes:
Ferris et al., 2001:
cp-1: mainly bacteria feeding nematodes (BF)
cp-2: mainly BF + Fungal feeders (FF)
cp3: FF, BF and carnivores etc.
For instance if I have a BF nematode what would be the cp value? Is it 1 or 1+2. Or else we give cp values 2 for a nematode having feeding types of BF + FF?
Appreciate your opinion.
Thanks.

Hello,
I am designing a new setup in which I will need to feed CO2 in different percentages (5-20%) to a reactor that will work at 450 °C and 60 bar. I am considering using liquid CO2 and pump it to the reactor. Does anybody have experience in doing that? Is it as simple as connecting the CO2 cylinder to a HPLC pump, or are there other critical aspects to consider, such as cavitation? Besides HPLC pumps, are there other devices/equipment that could do the task?
Thank you in advance for any help.

The working volume of the reactor is 80 liters, retention time is 40 days, and feed supplied to the reactor was at 5 days interval. The total solids of the feed are fixed at 10%. let's say the feed given on the first day is 3kg and the reactor was operated for 100 days at this organic loading rate. Now, in order to double the organic loading rate without changing the total solids, what should be the procedure.

For instance; I know the nutritional requirements of broilers and I also have data on the nutritional value of feed ingredients that I want to mix, now, how can I use excel to calculate & reach those requirements?
A document or a reference of a step-by-step guide on feed formulation in excel, or any written suggestion to simply calculate for 4 or 5 feed ingredients could be more helpful.
I have modelled a dipole antenna and want to attach an L-Network (having L-C/C-C/L-L) before the feeding port i.e. in between Antenna and Feed Port. I can easily include any lumped element in Parallel but I am unable to realise the same in series connections.
Hi,
SITUATION:
I am trying to recreate something similar to the inverter model contained in:
Conference Paper State-space model of an inverter-based micro-grid
There is a Droop Controller that feeds a Voltage Regulator that feeds a Current Regulator that powers a LCL filter.
MY PROBLEM:
1. When combining the Voltage and Current state models. A and C is 3x3, B and D are 2x8. I pad them out with redundant zeros to make them all 8x8, unsure if this correct? When I multiply them out as listed in the link below, I lose all the controller information from the Current Regulator, such as the integrator and proportional controller coefficients and the decoupling terms.
2. The Voltage and Current state models share the same inputs as the Droop controllers, so they are not perfectly in series. Is there a strategy to combine state space models that share inputs?
Thanks
