Get a real job and stay away from this !!

If you want to write esseys forspoiled brats who are too lazy to do it themselves and pay a miserable amount of money for it, then this is the right place for you. You have to write 2 works for free to be able to get in and then you have a lousy offer where you have to get the job before someone else. Not to mention they call you to check if you're actually doing the job, so you have to pay attention to their messages or calls, otherwise you lose the assignment. Even if you get paid once the work has been done, in case the client (spoiled brat from England or USA) is not satisfied with the work , you have to write the correction for free or else you lose the money. Is is totally not worth the effort, any copywriting job is better than this.

Termination of account unduly

Please , the company has one problem of which they I don't think what they are doing is good . First,my account was terminated due to suspicious activity related to my account which they claimed I did .and of which I have no idea of what they are saying Secondly , I have submitted a lot of test skills to them if when I know it is correct and cross check yet they told me to improve my skills my problem is now they can never tell you the problem with your account , I use the laptop I use to gain access to the company before .it was the same laptop I used to summit another test on calculation again ,I want to know if I can't use the same IP address I use to gain access before my account was terminated that I can't use it again to summit a new test

Don’t touch these guys with a barge…

Don’t touch these guys with a barge poll. For background, I have a degree from the University of Cambridge, and a Master’s and PhD from the University of Oxford. I applied for a freelance working role with these clowns without checking on here. I did the English test - which was riddled with grammatical errors - and then proceeded to the test task. I researched a wrote a 400 word ‘essay’ following a prompt and submitted. As a seasoned researcher, I added references and everything was written well. I received a report saying ‘After checking your test task, we have noticed that your academic skills need improvement and therefore we are not ready to offer you the position’. I asked for further information and they claimed ‘suspicious activity’ had been spotted by their system. So a machine had read my work, not a person. I presume they are referring to plagiarism which is quite a serious allegation. Livingston claim to have ‘high quality standards’. They should start by applying those standards to themselves.

This is a total scam!!

This is a total scam. I applied, did all their tests and got in. I was thrilled. I accepted my first order, which took a lot of research. It was a 1,600 word essay. They reviewed it, said I got 5 stars for it, and was well. My balance in my account was adding up. Then I receive an email, that said "suspicious activity" was detected on my account, and it is permanently disabled and cannot be reconsidered. Thus, I did all the work for nothing, didn't get paid and was totally scammed. DO NOT WORK FOR THIS FREELANCE COMPANY. Total scam.

They pays.....don't worry.....but still it is worst

"They pays.....don't worry.....pay rate is also good but your progress depends upon clients satisfaction.......there are some stubborn client who gets good marks for your work but also rates you with 1 star and asks for refund which is drawback of this company. But I have received $16 tips with 5 stars working for $5.4. So it's all about how good your client is. If your luck is not with you, it's sure you'll approaching such client and receive lots of fines & warnings. Overall, it is good, you can earn $10 - $20 per day." The above one I wrote after working on the platform for 2 months. Today I am editing the comment after 8 months and decreasing the rating because they disabled my account for nonsense reason. I had to travel to other country for my study purposes. After reaching my new location, I worked on 2 orders. Then they sent me a message stating that "suspicious activity was detected in my account". I asked what suspicious activity was conducted. They said that they can't disclose that information and permanently disabled my account. This is how they treat their freelancers. This big disadvantage of this platform overtakes all the advantages. So, better avoid this platform..........

A scam that baits & traps writers

I am furious with myself because I should have done some research on this business before giving them a whole month's worth of my sincere effort. Their good-looking website and techy platform fooled me. 1. Livingston Research facilitates student fraud. All of the work I completed after my evaluation was college-level work for students in the US and the UK. Submissions which are actually the final versions of assignments, projects, research, etc. 2.) The freelance writer is kept in check through the use of unfair fines for ridiculous errors that are never explained, nor do they enter into any discussion with you. 3.) Their direct deposit system is non-functional; you are compelled to open Payoneer or Skrill accounts, which have a bad reputation and are utilized by unscrupulous online gambling sites. 4.) After working for a month and having completed 14 jobs with a client score of 5 on 10 jobs, I was still a beginner. According to their training, you are put into groups that allow you to earn more after receiving five client scores. "Beginner" is the lowest-earning group. After a fortnight, I should have seen the telltale signs. Their correspondence, from the entrance exams to the weekly bonus notifications, is rife with grammatical errors. The response time differs depending on what you're querying. If it's about an unfair action they've done to you, there's never a response. To anyone considering Livingston Research, avoid these scammers. For those like me–licking their wounds–you're worth much more. Don't let these frauds break your spirit. Good luck & be well.

Here we Go! Received the email today that reads "Unfortunately, your account did not pass the Quality Assessment due to present quality and performance issues. As a result, we have to permanently disable your account. The decision is final and cannot be reconsidered". I was in beginner group and had completed 10 orders with rating 5 from two clients and average rating of 5 as well. How the heck they tell if it was quality issue? If it really would be quality issue I would not have achieved rating of 5 damn it. Shame I had enrolled myself in this s**t freelancing site. And moreover to add to it they blocked orders on 3rd of November and they do not tell you what really is going on with the account even if you mail them. All they say is there is not any issue with the account and you should keep checking the order section frequently and wait for the email if the issue pertains. At least tell the issue damn it so that we would be less patient knowing what exactly is going on. To add to it they made me do one pending order while the orders were blocked in find the orders section and also made me do the revision of one of completed order. Finally, all I can say is this company is a big s**t.

Yep, should have read these reviews first

Yep, I should have read here before applying to this company. Not only do they have errors in the "English test" they administer but they also have plenty of errors in the text of their website. Not sure what kind of "students" would want to get help with writing from these Ukrainian clowns. They should call themselves Shevchenko Resyurch. They gave me an extremely basic task that took only a few minutes to solve and rejected me as "failed" with a 1-star review. There was feedback so, I thought perhaps I would get an idea of what I had done wrong but it was nothing but a silly rating system on the following standards. Oddly, the assignment was nothing more than solving a future value problem in Excel. How can this be plagiarism? Anyway, you can see the kind of grammar errors their content is full of by reading the descriptions on the key points below. Plagiarism free The information that is not common knowledge is cited. Original writing is minimum 70%. Direct quotes do not exceed 10% of the required word count. Content The paper meets the Client’s requirements and does not contain any irrelevant or generic content. Sources The required by the Client, relevant (published within the last 5-7 years) and reliable sources are properly incorporated. Word count It is counted from the introduction to conclusion. Title and reference pages, as well as footnotes are excluded. Language and format 0.0 out of 2.0 Criterion Excellent Quite Good Average Poor Unacceptable Structure Thesis statement serves as a roadmap of the paper. Each paragraph is devoted to one idea. The paper is coherent and cohesive. Language Sentence structure and word choice are correct. No proofreading issues. Format

Scammer Scammers Scammers!!!

This is the worst freelance company i have ever come across. They wait for your earning to accumulate to big amounts before scamming you. Keep off from them!!!

This company is very useless and does not care about their employees. They find cunning ways to fine you 100% of all your order payments. Thieves, how can you fine me 100% for work I have wasted my time on

I would give this company 0 stars if I…

I would give this company 0 stars if I could. When you first start working for them, everything seems fine, but after you finish and send your orders, that's when the scam starts. Firstly, you'll receive casual reviewing requests, and they can apply fines to your work if they don't like it. Usually, they do apply fines. They can change the work you accepted while you're working on it and add extra work to your task without paying you more money. If you see these changes and don't want to work on the task, they'll give you a warning. And if you receive four warnings, they can terminate your account. They use you like slaves, making you obey everything they say. If they ask you to review and rewrite an essay, you have to, and if they ask you to do more tasks, you have to. The pay is also an issue. For the amount of work you do, you'll receive very little payment. Additionally, my account was terminated after I received four warnings, and they didn't even send me the money that was on my balance. In conclusion, they are scammers. Don't waste your time with this company. If they continue to treat their writers like this, they will go out of business.

Vague Assignment Instructions: please do not work for this company if you have other options available

Title: **"A Cautionary Tale for Freelancers: My Experience with Livingston Research"** Review: I am writing this review to share my experience with Livingston Research, a platform that I believe does not provide a conducive environment for freelancers. Here are the issues I faced: 1. **Vague Assignment Instructions**: The instructions provided for assignments were often unclear and lacked sufficient detail. This made it challenging to understand the requirements and deliver quality work. 2. **Unjustified Client Comments**: I received comments from clients that were subjective and lacked specific correction suggestions. This lack of objectivity made it difficult to improve my work or understand where I went wrong. 3. **Inconsiderate Time Management**: The company did not take into account the geographical location of freelancers when setting deadlines. This disregard for time zones created unnecessary pressure and stress. 4. **Frequent Deadline Changes**: Deadlines for revisions were frequently changed without prior notice. This unpredictability made it difficult to manage my workload effectively. 5. **Penalties and Increased Workload**: If a freelancer failed to meet the revised deadline, the company imposed severe penalties, including a 100% refund. They also increased the workload, which seemed like a punitive measure rather than a constructive one. 6. **Account Termination**: My account was terminated without any prior notice or clarification. This abrupt action left me without a platform to showcase my work and earn a livelihood. In conclusion, my experience with Livingston Research was far from satisfactory. The platform's practices were unfair and lacked transparency. I advise freelancers to consider these points before deciding to work with this company. It's essential to find a platform that respects your time, values your work, and provides a supportive and fair working environment. I hope my experience helps others make an informed decision. Please remember, your skills and time are valuable, and you deserve to be treated with respect and fairness.

Livingston is a fraudulent company. It’s all set up properly, and looks like a very good company for freelance writing jobs, I even recommended it to my friends the week I got accepted. Before I started, I saw bad reviews about the low pay and I was like “ it can’t be that bad, plus I love writing anyway, so it’ll be experience points for my CV”. But as I got access to their site for two months or so, I have insider information now. Here’s why you shouldn’t work there for any reason. 1. The low pay of course. It’s absolutely ridiculous. The best jobs you can get are for $15 - $20 and they are not worth it at all. You’d have to do hours of research, might have to watch a specific movie, read a specific textbook, use a vpn to access someone’s uni website from within the US, just to earn the $20. 2. YOU DON’T GET PAID. Let’s say you’re just like me and even though the research is super stressful, you genuinely enjoy writing and you have some extra time on your hand. The thing is, you still don’t get paid. It will show on your profile that you’ve earned a certain amount from your work. You literally cannot take it out tho. Their only modes of withdrawing funds are through Payoneer and Skrill. PAYONEER AND SKRILL ARE WELL-KNOWN FRAUDULENT PLATFORMS. Just look them up quickly and you’ll see for yourself. 3. Weirdly enough, they had a lottery last Friday where I supposedly won $50. I tried to divert my money (from writing and the lottery) from Livingston to either Skrill or Payoneer, but for some reason, I needed to have money in my account to activate them. I don’t know if there is a partnership between Livingston and Payoneer or Skrill, but I know for certain that it’s impossible to take out my money now. Luckily, I didn’t lose any penny but I’ve wasted all my time writing for two months, saving up cash in my Livingston account. Stay away from Livingston. Cheers.

Membrane fractionation of liquors from lignin-first biorefining.

For the purposing of each lignin fraction in the lignin liquors, the development of separation strategies to fractionate the lignin streams by MW ranges constitutes a timely challenge to be tackled. Herein, membrane separation was applied to the refining of lignin streams obtained from a lignin-first biorefining process based on H-transfer reactions catalyzed by Raney Ni, using 2-propanol as a part of the lignin extraction liquor and as an H-donor. A two-stage membrane cascade was considered to separate and concentrate the monophenol-rich fraction from the CUB liquor. Building on the experimental results, an economic evaluation of the potential of membrane separation for the refining of lignin streams was undertaken. The membrane performance represents the bottleneck of the costs associated with the separation process. Accordingly, we present a detailed analysis of future developments in the performance required to debottleneck the utilization of membrane separation for lignin refining.

Sequence-defined multifunctional polyethers via liquid-phase synthesis with molecular sieving

Synthetic chemists have devoted tremendous effort towards the production of precision synthetic polymers with defined sequences and specific functions. However, the creation of a general technology that enables precise control over monomer sequence, with efficient isolation of the target polymers, is highly challenging. Here, we report a robust strategy for the production of sequence-defined synthetic polymers through a combination of liquid-phase synthesis and selective molecular sieving. The polymer is assembled in solution with real-time monitoring to ensure couplings proceed to completion, on a three-armed star-shaped macromolecule to maximize efficiency during the molecular sieving process. This approach is applied to the construction of sequence-defined polyethers, with side-arms at precisely defined locations that can undergo site-selective modification after polymerization. Using this versatile strategy, we have introduced structural and functional diversity into sequence-defined polyethers, unlocking their potential for real-life applications in nanotechnology, healthcare and information storage.

Extended DLVO interactions of a metal-organic framework: Implications on colloidal dispersion

Iterative synthesis of sequence-defined, multifunctional, biocompatible pegs for biomedical applications, roll-to-roll dip coating of three different pims for organic solvent nanofiltration.

PIM-1, PIM-7, and PIM-8 composite membranes have been fabricated for Organic Solvent Nanofiltration (OSN) on two different support membranes. Both support membranes, PAN and crosslinked Ultem 1000, displayed pore sizes within the range of 20–25 nm as characterised by gas liquid porometry. PIM layers of < 500 nm thickness were formed from dip coating on a roll-to-roll pilot line. The resultant composite membranes exhibited typical MWCOs in the region of 500–800 g mol−1. The quality of coating obtained on the crosslinked Ultem 1000 support membrane was consistently higher for all three PIMs than that obtained on the PAN membrane. The PIM composite membranes coated on to crosslinked Ultem 1000 were stable in a wider range of solvents than those on the PAN support. OSN testing in a model system with isomeric alkane solutes verified that manipulated changes to the molecular architecture of the polymer backbone resulted in a higher separation factor between straight and branched alkane isomers.

Iterative peptide synthesis in membrane cascades: Untangling operational decisions

Membrane enhanced peptide synthesis (MEPS) combines liquid-phase synthesis with membrane filtration, avoiding time-consuming separation steps such as precipitation and drying. Although performing MEPS in a multi-stage cascade is advantageous over a single-stage configuration in terms of overall yield, this is offset by the complex combination of operational variables such as the diavolume and recycle ratio in each diafiltration process. This research aims to tackle this problem using dynamic process simulation. The results suggest that the two-stage membrane cascade improves the overall yield of MEPS significantly from 72.2% to 95.3%, although more washing is required to remove impurities as the second-stage membrane retains impurities together with the anchored peptide. This clearly indicates a link between process configuration and operation. While the case study is based on the comparison of single-stage and two-stage MEPS, the results are transferable to other biopolymers such as oligonucleotides, and more complex system configurations (e.g. three-stage MEPS).

Novel thin-film composite nanofiltration membranes with covalent organic framework active layer

A robust thin film composite membrane incorporating thermally rearranged polymer support for organic solvent nanofiltration and pressure retarded osmosis, pecvd modification of nano & ultrafiltration membranes for organic solvent nanofiltration, solvent-free coating of epoxysilicones for the fabrication of composite membranes.

Solventless coated epoxysilicone composite membranes have been prepared from a UV curable epoxysilicone polymer for organic solvent nanofiltration. Coatings were conducted solventless on a roll-to-roll pilot line using a forward gravure coating technique, and applied on a polyacrylonitrile or cross-linked poly(ether imide) support. Cross-linking of the poly(ether imide) support membrane with propanediamine enhanced the adhesion properties of the epoxysilicone selective layer. Penetration of the coating solution into the porous support membrane was confirmed using scanning electron microscopy with energy-dispersive X-ray spectroscopy. Membranes fabricated using two different gravure heads have been studied, with submicrometer siloxane layer thicknesses achieved. The separation performance of the membranes is observed to be independent of the thickness. It has been possible to achieve membranes with a molecular weight cut-off < 500 g mol–1 in hydrocarbon solvents. Benefits of the fabrication include the ability to UV cross-link under air, elimination of solvent-based coating, and the feasibility of achieving uniform, submicrometer coatings at large scale manufacturing. These membranes comprise a further step toward greener and safer membrane production.

Nanofiltration operations in nonaqueous systems

Nanofiltration is a pressure-driven membrane process used to remove solutes with molecular weight in the range of 200-2000 g mol-1, typically from aqueous streams. A relatively recent innovation is the extension of nanofiltration (NF) processes to organic solvents (OSs)-an emerging technology referred to as organic solvent nanofiltration (OSN). Separation of molecules present in OSs by NF has great potential in industries ranging from refining to fine chemical and pharmaceutical synthesis, and OSN is currently an area of intensive investigation. This article summarizes the most recent developments in the field of OSN.

Continuously Operated Hydroamination - Toward High Catalytic Performance via Organic Solvent Nanofiltration in a Membrane Reactor

Still, the hydroamination of dienes to form allylic amines is a challenging task in a continuous operation. Herein, we present the performance of a membrane reactor by the implementation of a continuously operated hydroamination reaction of β-myrcene with morpholine. Via application of a poly ether–ether–ketone (PEEK) membrane, operation at elevated temperatures was possible in an integrated reaction/separation unit. First, the kinetics of the hydroamination reaction and relevant membrane characteristics were determined under optimized reaction conditions. Afterward, these results were incorporated in a reactor/separator model to predict the process behavior. With this, catalyst replenishment was adjusted resulting in stable continuous operation. In the end an increase of the turnover number from 460 to 5135 compared to a batch process was achieved. The desired geranyl amines were obtained in very good yields higher than 80%, while an excellent conversion of β-myrcene above 93% was reached in a long-time stable process.

Liquid-phase iterative synthesis with OSN: A flexible and scalable platform for precision synthetic macromolecules

Neutron reflectivity and performance of polyamide nanofilms for water desalination.

The structure and hydration of polyamide (PA) membranes are investigated with a combination of neutron and X-ray reflectivity, and their performance is benchmarked in reverse osmosis water desalination. PA membranes are synthesized by the interfacial polymerization of m-phenylenediamine (MPD) and trimesoyl chloride (TMC), varying systematically reaction time, concentration, and stoichiometry, to yield large-area exceptionally planar films of ≈10 nm thickness. Reflectivity is employed to precisely determine membrane thickness and roughness, as well as the (TMC/MPD) concentration profile, and response to hydration in the vapor phase. PA film thickness is found to increase linearly with reaction time, albeit with a nonzero intercept, and the composition cross-sectional profile is found to be uniform, at the conditions investigated. Vapor hydration with H2O and D2O from 0 to 100% relative humidity results in considerable swelling (up to 20%), but also yields uniform cross-sectional profiles. The resulting film thickness is found to be predominantly set by the MPD concentration, while TMC regulates water uptake. A favorable correlation is found between higher swelling and water uptake with permeance. The data provide quantitative insight into the film formation mechanisms and correlate reaction conditions, cross-sectional nanostructure, and performance of the PA active layer in RO membranes for desalination.

Implication of Side Reactions in Iterative Biopolymer Synthesis: The Case of Membrane Enhanced Peptide Synthesis

Membrane enhanced peptide synthesis (MEPS) improves conventional liquid phase synthesis by purifying intermediate products via filtration. A challenging aspect of MEPS is the propagation of unreacted materials and byproducts throughout the iterative synthesis. In this study, we first develop and validate a model of MEPS. The model is then applied to investigate the implications of side reactions (i.e., formation of error sequences) due to incomplete reaction and insufficient removal of amino acids after coupling. Sensitivity analysis shows that increasing the reaction extent for all couplings from 90 to 100% reduces the yield of truncated sequences from 29 to 0%. The formation of repeating sequences is found to be negligible in all case studies due to the large diavolume of post-deprotection diafiltration. This study provides useful insights into the operation of MEPS with particular emphasis on the control of error sequence formation. These insights are transferable to other sequence-controlled biopolymer syntheses.

North Korean Missiles Rain Down on Ukraine Despite Sanctions

Russia has received new shipments of Hwasong-11 short-range ballistic missiles, according to a new report.

• Share full article

By John Ismay

Reporting from Washington

North Korea has continued to supply advanced short-range ballistic missiles to Russia in defiance of sanctions meant to prevent Pyongyang from developing such weapons and Moscow from importing them, according to a report by a weapons research group.

Remnants of four of the missiles, which are called Hwasong-11, were examined in Kyiv by investigators from Conflict Armament Research , an independent group based in Britain that identifies and tracks weapons and ammunition used in wars around the world.

That team decoded production markings on several parts from each missile collected by Ukrainian authorities.

A Hwasong-11 missile used in an Aug. 18 attack on Kyiv had markings showing that it was made this year. Internal parts from three others, which were used in attacks in July and August, lacked markings that would indicate when they were manufactured.

The researchers released those findings in a report on Wednesday.

In early January, the White House accused North Korea of providing ballistic missiles to Russia , but subsequent shipments had not been previously reported.

The Hwasong-11 missile has a range of about 430 miles and can be fitted with nuclear or conventional warheads, according to a U.S. Army report . It is visually similar to the Russian Iskander short-range ballistic missile and may have been made with foreign assistance, according to the Center for Strategic and International Studies, a Washington think tank.
