Outsmarting the Taxpayers
I'm sure there are arguments that it's financially efficient. That it preserves human capital. That it's better than alternatives. But when all th talking is done, this is just outrageous:
They left the state college system in droves in recent months to avoid paying more for their health insurance or losing it entirely, and they left with thousands of dollars in retirement incentives and severance payments for things like unused sick time.
But now, 44 retirees from Rhode Island College, the Community College of Rhode Island and the University of Rhode Island are back on the state payroll — in many cases, back in their old jobs as professors, administrators, school nurses, accountants and computer technicians while collecting state-subsidized pensions.
State law permits class instructors to remain on an explicitly limited basis, but the others are leveraging this bit of specious reasoning:
When asked, however, how that law justified the rehiring of top-level administrators, back-office financial staff and computer techs — including one CCRI retiree with a $44,412 state pension — spokesman Steven J. Maurano offered up a new and previously unheard of argument in the halls of state government, after consulting with Ron Cavallaro, general counsel to the Board of Governors for Higher Education.
Maurano said Cavallaro believes the law limiting which retirees can be rehired — and how much they can earn without giving up their retirement benefits — applies only to those enrolled in the state retirement system, not the vast majority of newly retired state college and university faculty and administrators enrolled in the privately operated TIAA-CREF, to which the state contributes 9 percent of pay annually for each enrollee.
Under that reading, Maurano said, the administrators of the state college system can bring back whomever they want, for however long they want, at whatever level of pay they deem appropriate without any loss of retirement benefits.
Most Rhode Islanders, one shouldn't have to explain, don't ever get the option to retire with a large incentive check and in time to preserve unsustainable healthcare benefits on a public-sector-level pension and keep the very same job on a lighter basis to make up (or exceed) the difference in income. This asserted loophole should be closed immediately and all cases retroactively challenged in court.
At the very least, very tight time constraints ought to be placed on the retiree-temps so that the organizations for which they work can absorb as much institutional knowledge as possible. Then the public-sector kings should be let out to pasture so that Rhode Islanders suffering from the nation's worst unemployment rate (and without pensions) can claim any positions that absolutely must be filled.

Aligning the commencement of pension payments with Social Security eligibility age would fix this in one fell swoop.
Oh for heavens sake, I am sick and tired of this crap excuse given by YAIE (Yet Another Idiot Educator) that the level of service would suffer if those 44 people weren't allowed to come back. IS HE FREAKIN' KIDDIN' ME?!?!?
Does anyone in this state really think that ANY of the presently enrolled students are going to suffer academically if those overpaid PENSIONED retirees weren't there? Haven't we all had some teaching staff quit or be replaced during our elementary, high school, secondary school or college schooling? Is there any of us who can say our lives suffered because a teacher left a position where we were a student or benefactor of their graces?
We have got to be the most retarded, the most inbred, stupid, double wide trailered people in the entire world to put up with garbage like this.
If WE ALL don't send some firey, tasty, salty letters to each and every one of those institutions that rehired the staff of 44 then we might as well go out to pasture and graze with the rest of the sheep.
What else can we do, huh? Oh wait, some of the IDIOTS in this state did vote for Paiva-Weed, Connors, Levesque, DuPonte, and the like. You are excused from being outraged, you are too STUPID to be upset.
Let me understand this, Justin and Tom W are against the public Employees' Retirement System of Rhode Island because it is a defined benefit system and after an employee works 38 years and contributes anywhere from 8.75% to 9.5% of their pay (which the state is suppose to match) each year that employee can retire at maximum 75% of pay. Any amount of years vested below 38 years there is a reduction in pension percentage. Under the new rules a public school teacher or state employee can collect a reduced benefits pension at age 59 with 29 years vested or age 65 with 10 years vested. Age 55 can collect a reduced benefits pension with 20 years vested. The common argument I hear is that there is "no risk" as in the private sector and the state employees, public school teachers, police and fire and municipal employees should be moved to a 401K plan in the private sector so they might inherit risk as in the private sector. The major risk is the state not putting in its matching funds thus undermining the retirement system. Now we have the state trying to balance the budget and the Board of Governors for Higher Education offering incentive payments for college personnel to retire in some cases early which reduces their individual pensions (also as they retire, state raises that were withheld during Gov. Sunderland to balance budget must be paid per agreement). Their retirement system is a private commercial system called Teachers Insurance and Annuity Association – College Retirement Equities Fund (TIAA-CREF). The state pays in a matching 9% (The state must pay its matching share to a private retirement system). They are not part of the Employees' Retirement System of Rhode Island they are part of a private pension system so… Read more »
"As for hiring 44 of them back part timer (19 hours a week or more) with no benefits, it's a lot cheaper than continuing to employ them at full salary with benefits. It's a lot cheaper than bring in new blood that has a 90 day startup risk and full benefits payment plus maybe higher wage requirements. Do the math!"
Are you thus saying that these education institutions could never hire new staff because of the startup risk? There's startup risk with every new hire so why should this fact be given any weight in rehiring old workhands?
Wouldn't you agree that there would have been a review of these positions to see if they were really needed at all?
Wouldn't it seem plausible that those 44 people knew about the loophole WELL before the early retirement cutoff date? and that they were probably ADVISED on how to take advantage of this loophole?
Furthermore, wouldn't it be of great discriminatory interest to know that they were DIRECTED to take advantage of this loophole thus blocking any advancement to the careers of junior staff members? Wouldn't that make a great EEOC lawsuit?
Furthermore, wouldn't it be of great discriminatory interest to know that they were DIRECTED to take advantage of this loophole thus blocking any advancement to the careers of junior staff members? Wouldn't that make a great EEOC lawsuit on the basis of a purported scheme to manipulate advancement opportunities for those junior members?
Maybe the ACLU could actually prove to be of value in this matter. Oh, nevermind about the ACLU part. They only go for unAmerican activities.
Roland, There had to be a review in order to determine asking theses specific 44 employees back part time. My understanding is most of them were brought back as Adjunct Professors in their respective fields. Can you tell me how many unemployed Adjunct Professors are walking the streets of RI? As for the computer employees, in my opinion, PeopleSoft software database is a nightmare to be involved with and requires trained personnel. So I can see retaining the PeopleSoft computer trained personnel as part timers. Many a state has dropped PeopleSoft and saved enormous amounts of money after dropping it. I'm surprised RI was using PeopleSoft! The startup risk is minimal with these 44 employees coming back as part timers because of the pervious on the job knowledge, internal routines and procedural understandings. I think it was a smart RI management money saving decision for a change. The end result is RI got rid of salaried employees and their benefits payments and got them back at hourly part time rates without benefit payment overhead or a "fixed contract". Roland are you suggesting in public and in writing that all the retirees and particularly these specifically "44 people knew about the loophole WELL before the early retirement cutoff date? and that they were probably ADVISED on how to take advantage of this loophole? Furthermore, wouldn't it be of great discriminatory interest to know that they were DIRECTED to take advantage of this loophole thus blocking any advancement to the careers of junior staff members?

Ken, what I am suggesting is that there is something amiss in the rehire status of these 44 people. The whole point of the early retirement was to reduce the financial burden to the state and not backfill these jobs. Instead, someone took it upon themselves, to go ahead and backfill these positions with the very same people that previously occupied them.
I do not know your contribution to the EEOC laws but I do remember from decades back that they were in place to create a 'fair' path for promotion within a work environment regardless of race, creed, culture, etc, etc, etc,…
First, these jobs should NOT have been backfilled thus saving the state millions. But if there were an impending need to fill those slots, then they should have been offered to internal employees first.
Which EEOC laws have been violated? Beats the heck out of me. AR and Projo aren't making a big deal out of this because this type of cocky behaviour seems to run rampant in the one-party governed state and it'll continue until people finally smarten up. I'm just your average Joe that's fed up with business as usual in this state.
I would like Maurano to answer this one question: Why was it THOSE 44 employees?
Monique(@monique-chartier)
Even the federal gov't stopped doing this a while ago.
What exactly did we accomplish by encouraging these forty four retirements?
Monique,
According to PROJO quote from "The spokesman for the state Office of Higher Education, Steven Maurano; Steven Maurano said;. "Even after deducting the millions in severance payments and the $377,000 paid this past semester to the select retirees who were rehired, he said the colleges could still save $11.4 million annually by leaving all of their current vacancies unfilled."
Gov Carcieri asked for budget cuts and Office of Higher Education responded with an $11.4 million annual cut still maintaining services.

Hubbert, PAWS and Errors head Doune for the barter
Doune the Rabbit Hole has announced an innovative ticketing scheme for this year's event, which takes place from August 22-24 at Cardross Estate, Port of Menteith.
Organisers need a variety of festival-related stuff, like a caravan, tents, yurts, generators, lights, furniture and decorations.
So, dounetherabbithole.co.uk. website now includes a 'Barter' page, allowing prospective festival-goers to either trade or lend something in return for tickets.
Artistic director Jamie Murray said: "You'd be surprised how many people have an old caravan kicking about that they don't know what to do with.
"If they aren't using it and would like a free festival ticket or two then we'd be very happy to do a trade.
In musical news, joining Jeffrey Lewis, Acid Mother's Temple, and Secret Chiefs 3 (a project by former members of Faith No More and Mr Bungle) are a host of new additions to the bill: The Amphetameanies, The Birthday Suit, Hector Bizerk, Blochestra, Errors, RM Hubbert, Kakatsitsi Drummers & Rebecca Vasmant, PAWS, Tom Snowball, Paddy Steer, The Telescopes, Trembling Bells, Samba Ya Bamba, Zea.

Who says it doesn't snow in Florida? Prepare for a Christmas miracle. Not one, but two different places in our Naples community celebrate a Naples Holiday Snowfall 2016: the Village Shops and Third St. One takes place on Christmas Eve and the other happens right before New Year's Eve.
Are you ready for Christmas? Still have last minute shopping to do? Visit the Village Shops on Venetian Bay this Saturday, December 24th. Cross the last names off your Christmas gift list. Then, watch the Naples Holiday Snowfall 2016 beginning at 4pm. Santa will be there to take requests from and photos with good little boys and girls. Mrs. Claus tells the BEST stories. Listen to carolers sing traditional holiday tunes. Dancers perform to classic Christmas music as well. Once you're done shopping and visiting with Santa, you might work up an appetite. Stop by one of the great restaurants inside Venetian Bay right on the water. Admission to the Naples Holiday Snowfall 2016 at the Village Shops is absolutely free of charge to the public.
The wintery fun doesn't stop there. If you can't make it to the Venetian Bay on Christmas Eve, you'll have another opportunity to enjoy Naples Holiday Snowfall 2016 action on Thursday, December 29th. That's when 3rd St South celebrates their holiday snowfall as part of its 3rd Thursday on 3rd celebration (even though it's technically the fifth Thursday of the month). Beginning at 7:30pm, snow falls on 3rd St and 13th Ave. While this happens, live holiday music plays in the background. Admission to this event is also free.
Looking for something special to do for the Christmas holiday? Have out-of-town guests you want to entertain? Visit one or both of the Naples Holiday Snowfall 2016 events taking place in the next several days here in the Naples/Marco Island area of Florida. Merry Christmas to all!
Who says it can't snow in Florida? Sure, we might have to truck it in. But the Naples Snowfest 2016 is worth it. Then, just a few days later, the Naples Christmas Parade treks through town. The holidays have officially arrived!
First, we kick off the holiday season with the Naples Snowfest 2016 this Saturday, December 3rd. Come see the Golden Gate Community Center transform into a winter wonderland. More than 1200 blocks of ice will be fed through an ice chipper to create 100+ tons of snow. Sled your way through the powdery stuff on the man-made toboggan hills. Pony rides, a petting zoo and an arts and crafts center allow kids to really get into the holiday spirit. Take the polar plunge without actually getting wet. This polar plunge involves a large inflatable slide and no water.
Try your hand at the holiday-themed carnival games. Hop aboard the carnival rides. Visit Santa at his temporary home away from home…the Florida "South Pole". For a small fee, your child can take a professional-quality photo with the jolly old elf himself. Don't forget to visit Mrs. Claus' kitchen for tasty treats cooked up with help from local civic groups.
The following Tuesday, grab your lawn chairs because the Naples 2016 Christmas Parade comes to town. From 6pm to 8pm, marching bands, floats and other fun entries parade down Naples streets to herald the holidays. The parade begins on Broad Street. It then makes its way north on 3rd St. Finally, it winds its way east on 5th Ave where it eventually ends at 8th St. You're welcome to line up anywhere along the parade route. Just get there early to find the best spot. I hear that Santa will be bringing up the rear of the parade. You won't want to miss it!

Starting a business that needs to import goods or services to the UK can be tough during these competitive times but knowing the range of eu countries that observe vat may help reduce costs. You will easily be in a position to track tax systems which are a lot like your while claiming vat refunds for previously paid vat in other countries.
There are several countries in the eu that also follow the system of vat. Although the language employed in the vat invoice might differ along with vat rates, the system followed is almost exactly the same. This list of countries checkvatnumber in the European Union which have adopted the system of vat are Estonia, Denmark, Bulgaria, Ireland, Latvia, Poland, Spain, Italy, Luxembourg, Belgium, Hungary, Slovak Republic, Czech Republic, Portugal, Sweden, Finland, Slovenia, Austria, Netherlands, Greece, Germany, France, Romania, Malta, Lithuania, and Cyprus. Some territories in this particular list of eu countries have however opted to stay out from the vat gambit. You can go to the hmrc vat or hm revenue and customs website to read about such territories.
One major advantage that you have when importing goods from such eu countries is that any vat which you may have paid in the particular country may be refunded to your account by that country once you apply for a vat reclaim. This procedure can be handled by an expert vat agent who has offices in the United Kingdom along with other countries from where your imports come about. Moreover, if you have attended trade shows inside a eu country and also have paid vat for the very same then such vat amounts may also be recovered back. This vat refund can surely help shore increase business net profit while suitably cutting your product costs.
If you hire a specialist vat, customs duties, and excise duties agent then that agent will also help calculate sales vat rates as well as file your vat returns in the stipulated time frame. Vat rates in the UK range from 17.5% for standard vat rates to 5% for reduced vat rates to zero vat rates for specific services and products. There are also specific products and services which are vat exempt. The hmrc website provides a detailed list of such services and products that are split up into 14,000 classifications.
To be able to claim a vat refund you will have to preserve and submit all original vat documents together with your vat certificate too. While procedures and language in several countries might pose a problem, a vat agent well versed in various vat systems must be able to recover your hard earned money back to your account. There are also different time limits within eu countries for submitting a vat reclaim and thus having an in-depth understanding of eu vat and uk vat rules will definitely provide a distinct advantage to you and your business.
If you want to import goods or services to the UK then choosing eu countries that follow vat would offer several distinct advantages. Knowing the list of eu countries that follow vat can certainly help save money as well as offer ease of operation because the system for paying and collecting vat would be the same in most these countries.

FREE COMPREHENSIVE ONLINE COVID-19 REHABILITATION PROGRAM LED BY ARISE UAE
UNDRR Private Sector Alliance for Disaster Resilient Societies (ARISE)
ARISE UAE in association with RAK Hospital launched the Middle East's first-ever comprehensive 'Online COVID-19 Rehabilitation Program', which will be offered to patients suffering from long COVIDsymptoms, completely free of cost. ARISE, the Private Sector Alliance for Disaster Resilient Societies is a network of private sector entities led by the UN Office for Disaster Risk Reduction (UNDRR).
According to the World Health Organization (WHO), COVID-19 rehabilitation improves the health prospects of COVID-19 patients through optimizing health and functioning outcomes, facilitating early discharge, and reducing the risk of re-admission.
After acute COVID-19 illness, recovered patients often continue to complain of chest pain, shortness of breath, fatigue, stress and anxiety, fatigue, body ache, cough, sore throat, difficulty in breathing, etc. Emerging evidence indicates that a majority of people who require hospitalization for COVID- 19 experience sequelae such as fatigue and shortness of breath in the months following their hospital discharge. Studies have also shown that the COVID causing SARS-COV-2 virus is likely to linger in the body, for many months. These problems have been described as 'Long COVID'.
It is observed that about 30% of COVIDpatients experience long-term debilitating or painful aftereffects of the disease, that hamper their ability to even perform simple daily tasks. Since it's a new disease, what we have learned so far is that the symptoms can continue for 3-9 months and pose challenges for people experiencing it. It not only affects patients who were severely sick or hospitalized but in many instances also impacted the ones who remained asymptomatic during the infection. The most common lingering symptoms include shortness of breath, chest pain, cough, or abdominal pain.
"It is an exclusive program for patients from across the globe. Nothing like this exists at the moment and we are extremely proud of our unique initiative which is supported and patronized by ARISE UAE. Ours is the only initiative providing an integrated and holistic approach to COVIDrecovery and rehabilitation, offered complimentary to all recovering patients", commented Dr. Raza Siddiqui, Executive Director, RAK Hospital, a multi-disciplinary hospital based in Ras Al Khaimah, UAE.
"Our aim at ARISE UAE is to create safe and resilient communities while working towards saving lives. COVID-19 being the biggest disaster of our times, needed our immediate attention, therefore, we felt it was necessary for us to work on presenting a solution which can help the communities not only in this country but worldwide as well. The RAK Hospital team had the required know-how to carry our vision forward, hence the concept is now a reality", stated Dr. Mahmoud Burai, Chairman of UAE ARISE and Senior Advisor in Dubai Government.
Led by Arabian Wellness & Lifestyle Management, RAK Hospital's wellness division, this comprehensive program combines the expertise of a multidisciplinary team comprising of physicians, nutritionists, psychologists, and physiotherapists who have worked hard to develop and deliver this idea.
"RAK Hospital had introduced its physical post COVID recovery rehabilitation program last year. However, we wanted to extend our reach to larger communities and wider geographies, thus, to support the community in the comfort of their homes, we created our online COVID Rehab product which assesses the recovering COVID patients' medical details, test results, comorbidities, symptoms, etc. and instantly makes available a comprehensive online COVID rehab health prescription for a speedy recovery, covering all areas including Medical, Exercise Activity, Nutrition & Diet, Stress and Mental wellbeing, etc.", commented Prof. Adrian Kennedy, Chief Wellness Officer, Arabian Wellness & Lifestyle Management.
Talking about ARISE UAE, Dr. Tariq Ahmed Nizami, Vice- Chairman, UAE ARISE and Founder and CEO of CEO Clubs Network Worldwide said, "The need to create risk-resilient societies is inevitable in today's environment, and by forming the first national ARISE in September of last year, we have shown that the UAE is leading the private sector engagement for disaster risk reduction. ARISE UAE aims to achieve the outcomes and goals of the Sendai Framework in a transparent and inclusive way that delivers measurable impact and sets the roadmap for other Arab countries. COVID-19 has put a stark reminder to all of us that reducing the risk of disasters, whether natural, man-made or biological, has to be everyone's business".
ARISE works towards a resilient, prosperous future where fewer lives are lost to disasters, capital assets and investments are risk-informed, and infrastructure is resilient to natural and man-made hazards. Members voluntarily commit to support and implement the Sendai Framework Disaster Risk Reduction 2015 – 2030, aligned with the 2030 Agenda for Sustainable Development and its Sustainable Development Goals (SDGs), Paris Climate Agreement, New Urban Agenda, and Agenda for Humanity.

The new Samsung tablets are finally official so here's what you need to know about the Galaxy Tab S2 including release date, price and specs.
As per rumours, Samsung has updated its Galaxy Tab S tablets with second generation models, which we're hoping to see more on at today's Unpacked event. Coming in at 8- and 9.7in, here's everything there is to know about the Samsung Galaxy Tab S2 release date, price and specs. Also see: Best new tablets coming in 2015.
Last year Samsung launched the Galaxy Tab S range bringing the 'S' from its smartphone over to the tablet side. We reviewed the Galaxy Tab S 8.4 and Galaxy Tab S 10.5 with the conclusion they were the firms best ever tablets. So we've been looking forward to finding out what Samsung would bring to the table with the Galaxy Tab S2 and the wait is over.
"The Galaxy Tab S2 is not only our thinnest and lightest tablet of its size ever, it also gives users quick, easy access to a wealth of superior viewing and productivity features," said JK Shin, president of Samsung Mobile. "We believe the Samsung Galaxy Tab S2 is the most complete personal visual device designed for consumers to carry and use anywhere."
Read on for an overview of the new features and release date information for the Galaxy Tab S2 in the UK, or for a closer look visit our Samsung Galaxy Tab S2 hands-on review.

Not quite as thin as leaked information said, the Galaxy Tab S2 tablets are just 5.6mm thick and weigh 265g (8.0) and 389g (9.7) respectively. That's still impressively svelte though with the previous models at 6.6mm.
The screen size has dropped on both models and so has the resolution, from 2560 x 1600 to 2048 x 1536 but Samsung has stuck with its preferred Super AMOLED technology. The firm says they deliver 94 percent Adobe RGB and other display features include Adaptive Display which automatically adjusts gamma, saturation, and sharpness and Reading Mode which gives you the right brightness.
Making the screens smaller is interesting, especially on the larger model which now matches the iPad Air 2 and Samsung has changed the design from predominantly landscape to portrait, again mirroring its Apple-made rival.
1.3GHz Cortex A53 cores) and a Mali T760MP6 GPU. That's the same chip as found in the non-Snapdragon Galaxy Note 4 and there's also 3GB of RAM.
Both have an 8Mp rear camera, 2.1Mp front camera, 11ac Wi-Fi, Bluetooth 4.1, GNSS and optional 4G LTE. You'll be able to buy the Galaxy Tab S2s in either 32- or 64GB storage capacities and the tablets have a Micro-SD cards slot which can take up to 128GB.
Of course, Android 5.0 Lollipop is pre-installed and you'll also get Microsoft Office and 100GB of OneDrive storage free for two years. Software features include Pop-Up Window and Smart Manager which 'displays the device's settings automatically, including battery power levels, storage and RAM availability for users to efficiently manage their devices'.

This work numerically studies the flow pattern of a magnetic fluid filled within an annulus whose inner cylinder is moving at a constant rotational speed, while the outer cylinder is stationary but under the influence of a nonuniform external magnetic field. The magnetic field consists of four basic configurations, that is, completely circular, semicircular, quarter circular, and alternately quarter circular. The strength of the external magnetic field is characterized using a reference Hartmann number. As the reference Hartmann number increases, the fluid elements need to overcome greater resistance to enter the region with magnetic field. Hence, there always exists an apparent recirculation cell within the region without externally applied magnetic field. The strength and size of the recirculation cell depend on the reference Hartmann number, the number and size of the discrete regions without external magnetic field. Only the shear stress on the moving cylinder always increases in magnitude with the reference Hartmann number and the span of the single external magnetic field region. Splitting and separating the external magnetic field may increase the magnitude of the shear stress on the moving inner cylinder but decrease that on the stationary outer cylinder. If the magnitude of the shear stress on the outer cylinder reduces beyond zero, a shear stress in the opposite sense will increase in magnitude with Hartmann number.
The study of magnetohydrodynamics (MHD) has recently become a topic of study which has attracted a lot of attention. In the 1960s, Papell of NASA mixed very fine magnetite particles below 10 nm with appropriate surfactant so that the nanomagnetite could be effectively dispersed in nonpolar solvents [1]. He then successfully produced a magnetic fluid which had demonstrated many very distinctive physical behaviors. In general, magnetic fluid can be classified as either conducting or nonconducting depending on their nature of electric conductivity. Under the influence of an external magnetic field, a conducting magnetic fluid in motion will produce an electromotive force that causes an induced electric current to flow. The presence of this induced electric field then in turn produces an induced magnetic field. At the same time, the induced electric field interacts with the overall magnetic field to produce Lorentz force that acts on the fluid elements. Since the Lorentz force acts to oppose the mechanisms that create it, it therefore generally serves to reduce the magnitude of fluid element velocity field.
As a matter of fact, Hartmann, way ahead of Papell's study, had successfully investigated the nature of magnetic Poiseuille flow based on experimental and theoretical approaches as early as 1937 [2]. His study was later referred to as the well-known Hartmann flow and the dimensionless parameter appeared in the problem was named after him as the Hartmann number. This parameter basically represents the relative importance between the magnetic and the inertial forces. In 1970, Finlayson [3] performed a theoretical study of a magnetic fluid behavior under the influence of perpendicular uniform external magnetic field.
Chang and Lundgren [4] have also performed a rather complete investigation on Hartmann flow. In their paper, they pointed out that the flow at the middle between the upper and lower surfaces tends to become flatter as Ha increases. Not only so, the overall velocity of the fluid decreases with Ha. In 1999, Yamaguchi et al. [5] studied the instability of magnetic fluid in a two-dimensional enclosure subjected to an external magnetic field through experimental and numerical simulations. As of this moment, magnetic fluid is widely employed in various engineering applications.
(a) Medical Therapy
For cancer detection, magnetic fluids are commonly used as the MRI contrast agents. Moreover, magnetic fluid is also used in experimental cancer treatments named magnetic hyperthermia.
(b) Seals for Electronic Devices
Magnetic fluids are used to form liquid seals surrounding the driver shafts in hard disk drives. A small amount of oil-based magnetic fluid can be injected into the gap between the magnet and the rotating shaft. The magnetic attraction holds the fluid in place forming a protection that prevents dusts from entering the hard disk drive.
(c) Lubrication
Oil-based magnetic fluids are also excellent lubricants. They can be injected into the gaps between moving mechanical parts of distinctive speeds. During operation, the leakage of the fluid can be prevented under the influence of magnetism. This feature is highly valued in the industry for it greatly reduces the hassle for consistent lubricant refill [6].
(d) Transportation
Magnetic fluids are now widely used in the magnetorheological damper, a kind of active suspension system surrounded with an electromagnet. The viscosity of the magnetic fluid in this kind of vehicle damper can be dramatically varied to account for the driver preference or the vehicle overall weight. More importantly, its viscosity may be dynamically regulated to improve overall vehicle stability control because the damping factor of the active suspension system can be adjusted once every millisecond in response to actual road conditions. As a matter of fact, magnetorheological dampers are also used in helicopter cockpit seats as safety devices which serve to significantly decrease the rate of permanent injury during a crash.
(e) Energy Conversion
The energy conversion device using magnetic fluid is attractive for space use or in a situation where no maintenance is required. Yamaguchi et al. [7] have designed and constructed a direct-heat-to-power energy conversion device that makes use of temperature-sensitive magnetic fluid.
For a very long period of time, fluid behaviors between a pair of independently rotating cylinders have been investigated extensively. Perhaps all studies in rotational MHD flow trace back to the work by Taylor [8, 9] who has investigated both theoretically and experimentally the stability of the classical Couette-Taylor flow. Shortly after Taylor's discovery of the onset of axisymmetric Taylor vortices, Jeffreys [10] has extended the concept of Couette-Taylor flow and shown that the earth rotational motion has a negligible influence on the mantle convective motion. On the other hand, Meksyn [11] has investigated a similar problem using a different asymptotic method of integration. Later, Coles and van Atta [12–14] disclose nonaxisymmetric spiral vortices as a result of counter-rotating cylinders. Since then, just to name a few, many monumental studies [15–27] mostly deal with flow instability have been reported laying a solid foundation and inspiration for numerous future research topics and activities.
As a matter fact, Chandrasekhar [27] has recognized the need for further understanding of magnetic fluid instability associated to rotating cylinders. He extended the work by Taylor, Jeffreys, and Meksyn and considered an electrically conducting under the influence of an axial magnetic field. There are several factors affecting the effectiveness of the magnetic field in suppressing the onset of thermal instability. However, instability suppression due to the presence of the magnetic field is always more pronounced for rotational motion than for differential heating from below. While there were many research works related to a disk configuration, Donnelly et al. [28–30], Brahme [31], Ji et al. [32, 33] have contributed to the understanding of megnetorotational instability (MRI) in rotating fluid.
Despite the vast collection of MHD Couette flow problems, rarely found are those not tackling instability problems. Willis and Barenghi [34] investigated the response of a conducting liquid in a three dimensional cylindrical geometry subjected to an imposed axial magnetic field. The patterns of a typical nonlinear steady hydromagnetic flow were shown. Because of the magnetic field, the Taylor cells found in classical Coutte-Taylor flow are apparently elongated in the axial direction.
Szklarski and Rüdiger [35, 36] have actually simulated a magnetorotational MHD Taylor-Couette flow with an external helical magnetic field at small Prandtl number limits. Through plots of stream function contour, they showed the existence of drifting vortex pairs within an infinitely long annular space. For an enclosure with a motionless bottom endplate and a rotating upper endplate, a traveling wave propagates in the upward axial direction dramatically distorting the drifting vortex pairs observed in infinitely long annulus. The formation of Ekman-Hartmann layer is observed near the endplates where a Hartmann current exists and penetrates the bulk of the conducting fluid.
The purpose of this paper is to numerically study the flow pattern of a magnetic fluid filled within an annulus under the influence of different nonuniform externally applied magnetic field configurations. Based on the flow field obtained for different magnetic field configurations and field strengths, the shear stress along the moving cylinder is evaluated.
The description for the formulation of the magnetic fluid confined within a pair of infinitely long cylinders is given in Section 2. The governing equations along with the appropriate boundary conditions were made dimensionless and numerical approach was employed to solve the equations. The flow patterns of the magnetic fluid under the influence of the nonuniform externally applied magnetic field are investigated in Section 3. It is shown that the flow pattern depend strongly on the Hartmann number, that is, the strength of the external magnetic field. In particular, it is shown that the configuration of the external magnetic field plays a very important role in local acceleration and deceleration of the magnetic fluid. The change in shear stress due to the change in flow pattern is also documented. Finally, some important findings are reported in Section 4.
2. Governing Equations
Current work numerically simulates the flow field of a two-dimensional cylindrical magnetic Couette flow. The polar coordinate system is represented by (𝑟,𝜃), while the velocity and external magnetic fields are represented by (𝑢𝑟,𝑢𝜃) and (𝐵𝑟,𝐵𝜃), respectively. The radii of the inner and outer cylinders are represented by 𝑟𝑖 and 𝑟𝑜. Also, the inner cylinder rotates at a constant speed Ω.
The behaviors of electromagnetism are governed by the Maxwell's equations. As a matter of fact, these equations are a collection of four fundamental governing equations individually known as the Gauss's law, the Gauss's law for magnetism, the Faraday's law of induction, and the Ampère's law with Maxwell's correction. Together with the so-called material equations, these equations are mathematically given as [37] ⃗⃗𝜕⃗𝐵∇⋅𝐵=0,(2.1)∇×𝐸=−,⃗⃗𝜕𝑡(2.2)∇×𝐻=𝑗,(2.3)∇⋅𝐷=0,(2.4) where the above parameters are interrelated through the following relationships: 1𝐻=𝜇⃗⃗⃗⃗⃗𝐵⃗⃗𝐵,(2.5)𝑗=𝜎𝐸+𝑉×,(2.6)𝐷=𝜀𝐸.(2.7)
Combining (2.1), (2.2), (2.3), (2.5), and (2.6), the general magnetic field equation for any magnetic fluid can be obtained in the following form: 𝜕→𝐵+𝜕𝑡→𝑉⋅∇→𝐵+∇⋅→𝑉→𝐵=→𝐵⋅∇→𝑉+1∇𝜇𝜎2→𝐵.(2.8)
Although one can clearly understand the relationships and behaviors between the magnetic and electric fields, the theory of electromagnetism has also suggested that an electromagnetic force namely the Lorentz force will be produced in the magnetic fluid as it flows in the region under the influence of magnetic field. This force later tends to influence the motion of the fluid elements. For this reason, the magnetic, electric, and flow fields are interinfluential. The conservations of mass and momentum of the fluid are governed by the continuity and Navier-Stokes equation as 𝐷𝜌𝐷𝜌𝐷𝑡=0,→𝑉𝐷𝑡=−∇𝑝+𝜌→𝑔+1𝜇∇×→𝐵×→𝐵+𝜇∇2→𝑉.(2.9)
Current study assumes that the magnetic fluid is steady, incompressible, and laminar while the gravitational acceleration is negligible. Equation (2.9) simplifies as ∇⋅→𝑉=0,(2.10)→𝑉⋅∇→𝑉1=−𝜌∇𝑝+→𝑔+1𝜇𝜌∇×→𝐵×→𝐵+𝜈∇2→𝑉.(2.11)
With the help of continuity equation, (2.8) can be further simplified to give →𝑉⋅∇→𝐵=→𝐵⋅∇→𝑉+1∇𝜇𝜎2→𝐵.(2.12)
The external magnetic field varies as a function of radial direction, that is, 𝐵0/𝑟, where 𝐵0 will then be used to define the reference Hartmann number in current study. The dynamical state of the magnetic fluid can therefore be determined by solving (2.10)–(2.12) simultaneously. This set of equations is apparently too complicated to be solved directly. To further simplify it, stream function 𝜓 is introduced to eliminate the continuity equation and thus to reduce the number of equation needed to solve simultaneously. The stream function 𝜓 is defined such that 𝑢𝑟=1𝑟𝜕𝜓𝜕𝜃,𝑢𝜃=−𝜕𝜓,𝜕𝑟(2.13) where 𝑢𝑟 and 𝑢𝜃 are the dimensionless radial and azimuthal components of velocity. On the other hand, the following dimensionless parameters are also introduced to normalize the remaining set of equations: 𝑟∗=𝑟𝑟𝑖,𝜓∗=𝜓𝜈,Ω∗=Ω𝜈/𝑟2𝑖,𝜔∗=𝜔𝜈/𝑟2𝑖,𝐴∗=𝐴𝐵0𝐵,Ha=0𝑎𝑟𝑖𝜎.𝜌𝜈(2.14)
The parameter Ha is referred to as the reference Hartmann number because the term 𝐵0/𝑟𝑖 is actually the amount of reference external magnetic field density at 𝑟𝑖. Clearly, a larger Ha indicates a stronger external magnetic field 𝐵0. The parameters appeared within the square root are merely electrical and mechanical properties of the magnetic fluid. To simplify the formulation, the distribution of the magnetic potential 𝐴 is more frequently solved to replace the magnetic field density. The magnetic potential 𝐴 is defined similar to the stream function and is given as below for a two-dimensional formulation 𝐵𝑟=1𝑟𝜕𝐴𝜕𝜃,𝐵𝜃=−𝜕𝐴.𝜕𝑟(2.15)
Neglecting displacement currents, induced magnetic field, dissipation, and Joule heating, the Navier-Stokes equations can be transformed into the following nondimensional stream function-vorticity form after dropping the asterisk in (2.14) for simplicity: 1𝑟𝜕𝜔𝜕𝑟𝜕𝜓−1𝜕𝜃𝑟𝜕𝜔𝜕𝜃𝜕𝜓=1𝜕𝑟𝑟𝜕𝑟𝜕𝑟𝜕𝜔+1𝜕𝑟𝑟2𝜕2𝜔𝜕𝜃2−Ha2𝑟2𝜕𝐴𝜕𝜕𝜃−𝜕𝑟𝜕𝐴𝜕𝜕𝑟𝜕𝜕𝜃𝑟𝜕𝑟𝜕𝐴+1𝜕𝑟𝑟𝜕2𝐴𝜕𝜃2,(2.16) where the definition of dimensionless vorticity is given below without asterisk1𝑟𝜕𝑟𝜕𝑟𝜕𝜓+1𝜕𝑟𝑟2𝜕2𝜓𝜕𝜃2=−𝜔.(2.17)
To be consistent, the dimensional magnetic field equation, (2.12), was also nondimensionalized and simplified after some manipulation to yield 1𝑟𝜕𝐴𝜕𝑟𝜕𝜓−1𝜕𝜃𝑟𝜕𝐴𝜕𝜃𝜕𝜓=1𝜕𝑟𝑟𝜕𝜔𝜕𝑟𝜕𝐴−1𝜕𝜃𝑟𝜕𝜔𝜕𝜃𝜕𝐴+1𝜕𝑟𝑃𝑚1𝑟𝜕𝑟𝜕𝑟𝜕𝐴+1𝜕𝑟𝑟2𝜕2𝐴𝜕𝜃2,(2.18) where 𝑃𝑚 is the magnetic Prandtl number defined as 𝑃𝑚=𝜇𝜎𝜈.
Appropriate boundary conditions for the velocity field are imposed by specifying the values of dimensionless stream function on the surface of the inner and outer cylinders. After dropping the asterisk, they are given in terms of dimensionless rotational speed of the inner cylinder as
Inner cylinder,𝑟𝜓=𝑜−𝑟𝑖𝑟𝑖Ωat𝑟=1,(2.19a)
Outer cylinder,𝑟𝜓=0at𝑟=𝑜𝑟𝑖.(2.20a)
Other than the above velocity boundary conditions, an external magnetic field must be imposed on the magnetic fluid. The various configurations of the externally applied magnetic field considered in this study are shown in Figure 1. The dimensionless magnetic potential within the region ℛ including its inner and outer bounds where the magnetic field is externally applied is given as

Region without magnetic field, 𝑟𝐴=0for1≤𝑟≤𝑜𝑟𝑖,𝜃⊄ℛ.(2.22a)
In the present work, a finite difference method was employed. The governing equations (2.16)–(2.18) were approximated by algebraic equations at the nodal points over the computational domain. A finite volume was constructed surrounding each nodal point. The governing differential equations were then integrated over the control volume. This ensures that the conservation laws were satisfied both over the control volume as well as the computational domain. This numerical method has been successfully employed by the authors [38]. The geometry and grid system of the annular space was constructed using a structured orthogonal mesh system. The grid distribution in this work was 40×260, as shown in Figure 2. Under- and over-relaxation was employed for most of the calculations to ensure the efficiency and accuracy of the numerical results. The reference Hartmann number investigated in this work includes 1, 3, 5, 10, 20, 30, 40, and 50. A grid refinement test had been performed and it was found that there was no significant improvement on present computational results even if the number of grid was increased up to 8 times denser than the current one.
Grid distribution.
Since the magnetic fluid flow in the annular space is subjected to an external magnetic field, its fluid elements experience either a local acceleration or a local deceleration. It has long been recognized through various studies that as Ha increases, the velocity close to the inner cylinder decelerates while that close to the outer cylinder accelerates. Not only so, the velocity gradient at the surfaces of both the inner and outer cylinders increases with Ha. In current study in which the external magnetic field is regional, it is found that the velocity gradient becomes relatively more obvious when Ha>20. For this reason, the discussion that follows will only focus on the scenario where Ha=30 and 50. In order to further examine these phenomena, this paper divides the upper half section of annulus (i.e., 0° ≤ θ ≤ 180°) into 12 sections which are 15° wide. These cross-sections between these sections are shown in Figure 3.
Locations where the velocity profiles are displayed.
The contour of stream functions for Ha=30 is presented in Figure 4. Since the external magnetic field is completely circular within the annular space, the flow patterns are certainly axis-symmetrical. This fact is evident from the distribution of stream function contours. It can be seen that the contours of stream functions appear to be a family of concentric circles. In other words, the magnetic fluid is merely a swirl flow under the influence of the complete circular external magnetic field proving the fact that the flow field is completely one-dimensional and angular independent.

Figure 5 shows the contours of stream functions for the magnetic fluid subjected to a semicircular external magnetic field of Ha=30. Unlike the previous case, there exists in the lower portion of the annular space an additional recirculation cell rotating in the clockwise direction. The eye of the cell is located to the right side of the annulus in the region without external magnetic field. Clearly, the flow pattern is no longer axis-symmetrical. Remember that the magnetic field is only applied in the upper half of the annulus. In this region with an external magnetic field, the magnetic fluid simply flows in the counterclockwise direction. In the lower half where the external magnetic field is absent, the region is mostly occupied by a recirculation cell. The formation of the recirculation cell is solely due to the presence of the external magnetic field in the upper half region. In the upper half region, the fluid elements generally slow down under the influence of the Lorentz force. Prior to entering the upper half region, the fluid elements in the lower half region has experienced a considerable flow resistance. Hence, some of the fluid elements are forced to flow radially outward similar to the phenomena discovered for flow impingement. This radially outward flow eventually forms the recirculation cell. It is remarkable to see that only a very thin layer of magnetic fluid right next to the inner rotating cylinder is capable of penetrating the upper half region because the flow momentum at this region is continuously supplied by the rotation of the inner cylinder. Once it enters the upper region where the recirculation cell is no longer present, it expands almost radially and therefore fills the entire gap between the inner and outer cylinders. As it leaves the upper half region and returns to the lower half region, its fluid elements are squeezed radially inwards by the recirculation cell. Even though the phenomena of magnetic fluid entering and leaving the upper half region is somewhat similar (but in a reversed fashion), the change in velocity field is more abrupt for the magnetic fluid elements entering than leaving the region subjected to an external magnetic field.

In Figure 6, 𝑅∗=0 and 𝑅∗=1 indicate the locations of the inner and outer cylinders, respectively. Here, the aforementioned radial coordinate was scaled through 𝑅∗=(𝑟−𝑟𝑖)/(𝑟𝑜−𝑟𝑖). Similarly, the angular velocity component 𝑢𝜃 of the magnetic fluid was calculated through (2.10) and then normalized by the linear velocity of the inner cylinder, that is, 𝑉∗=𝑢𝜃/𝜔𝑟𝑖. Apparently, the fluid elements on the inner cylinder move at a finite tangential velocity while those on the outer cylinder remain motionless. Furthermore, there exists a section close to the outer cylinder whose angular velocity component is less than zero at θ = 0° indicating that the fluid elements at this section actually flow in the direction opposite to the direction of the rotating inner cylinder. At other locations, that is, 30° ≤ θ ≤ 180°, the angular velocity profiles are almost identical. Based on this figure, it is not difficult to see that the magnitude of the normalized angular velocity 𝑉∗ in the region corresponding to 0.12 ≤ 𝑅∗ ≤ 0.84 and 30° ≤ θ ≤ 180° is about 0.06. This implies that the rotational speed in this region is inversely proportional to its radial distance.
Angular velocity profiles at 0° ≤ 𝜃 ≤ 180° subjected to a semicircular external magnetic field.
If the external magnetic field is applied at the first and third quadrants, the flow patterns can be expected to bear some resemblances with that for a semicircular magnetic field. Since there are two discrete regions without external magnetic field in this case, there surely exist two recirculation cells within these regions, as clearly displayed in Figure 7. However, the strength of these two cells is actually weaker than the single cell for the case shown in Figure 5. This can be imagined as if the single recirculation cell in Figure 5 is forced to split into two recirculation cells by the presence of the additional region with external magnetic field. As the single larger recirculation cell splits into two smaller cells, their strength apparently weakens. This means the fluid elements in Figure 7 circulate at a lower velocity. In the regions with external magnetic fields, the distribution of stream function contours in general is less dense in Figure 7 in comparison with those depicted in Figure 5. This clearly suggests that, except in the vicinity very close to the rotating inner cylinder, the majority fluid elements flow slower if the single region with an external magnetic field is split and separated. This phenomenon implies the decrease in flow kinetic energy in the annular space is attributed to the effect of additional flow deceleration and acceleration prior to crossing the interface between the regions with and without external magnetic field. Based on a careful comparison, it was also found that the flow in this case has to squeeze itself through a slightly narrower gap between the recirculation cell and the surface of the inner rotating cylinder.

To further understand the nature of the magnetic fluid flow, the velocity profiles in the upper half region of the annulus are plotted in Figure 8. It is observed that at θ = 0°, there is a large section where flow reversal takes place. Among the various velocity profiles demonstrated, the angular velocity component is all greater than 0 for 15° ≤ θ ≤ 120°. Although the external magnetic field is only applied at 0° ≤ θ ≤ 90°, the upstream recirculation cell actually stretches beyond the interface at θ = 0° while the counter-clockwise swirl flow extends over θ = 105° which is beyond the other interface at θ = 90°. In this region, the velocity profiles at 30° ≤ θ ≤ 90° are almost the same.

The flow pattern of the magnetic fluid in the annular space under the influence of a three-quarter-circular external magnetic field is shown in Figure 9. In this scenario, only the forth quadrant is not subjected to an external magnetic field. In Figure 9(a), the strength of the external magnetic field is associated to Ha=30. The flow patterns of fluid elements entering the region subjected to an external magnetic field are very similar to the previous cases. However, the flow pattern of the fluid elements leaving the region is very distinctive. Under the influence of the external magnetic field spanning over the upper half region as in Figure 5, the fluid elements are enormously squeezed so that they manage to complete a cycle. If the external magnetic field is split, separated, and applied alternatively over the upper and lower half semiannular spaces as in Figure 7, the fluid elements still need to force their way through the annular space. When an additional external magnetic field is applied at the second quadrant as in Figure 9(a), the fluid elements actually experience less resistance when flowing through the region without external magnetic field.
Distributions of the contours of stream function for a three-quarter-circular external magnetic fluids of (a) H a = 3 0 and (b) H a = 5 0 ( Δ 𝜓 = 0 . 0 0 2 5 ) .
Based upon these figures, it is remarkable to find that the strength and size of the recirculation cell are strongly dependent on the number of the discrete regions without external magnetic field and their span in the angular direction. Among these three external magnetic field configurations, the recirculation cell is the weakest when only a quarter of the annular space is free of external magnetic field. As the span of this region without external magnetic field is doubled, the strength of the cell increases due to the decrease in Lorentz force, as evidently shown in Figure 5. If the second and third quadrants of a semicircular external magnetic field (in Figure 5) are interchanged to form the two quarter-circular external magnetic fields, the recirculation cell is also split into two individual cells whose strengths are apparently less than the previous one.
Figure 9(b) shows the flow pattern for the same conditions except that Ha is increased to 50. The flow pattern is quite similar to that in Figure 9(a) except at the regions in the vicinity of the recirculation cell. Because of the increase in the reference Hartmann number, the corresponding recirculation cell grows in strength and as a result it leaves the swirl flow less space to go around. Also for this reason, the change in flow direction prior to the formation of the recirculation cell is much more dramatic for Ha=50 than for Ha=30. This also clearly proves that the strength of the recirculation cell for Ha=50 is greater between the two cases. As the fluid elements enter the region with an external magnetic field of Ha=50, they also tend to change their flow directions more rapidly under the influence of stronger Lorentz force.
If the external magnetic field conditions shown in Figure 9 are interchanged to form a quarter circular magnetic field, the general flow patterns interchange between the regions with and without external magnetic field. As shown in Figure 10, the strength of the recirculation cell actually increases tremendously as evidently depicted by the denser distribution of the contours surrounding the eye of the recirculation cell. More surprisingly, this recirculation cell is even stronger than the one shown in Figure 9(b), which corresponds to Ha=50.
Distributions of the contours of stream function for a quarter-circular external magnetic fluids of H a = 3 0 ( Δ 𝜓 = 0 . 0 0 2 5 ) .
The shear stress 𝜏 on the inner and outer cylinders were nondimensionalized by the product of the inner cylinder rotational speed 𝜔 and the fluid dynamic viscosity 𝜇. The dependence of these dimensionless shear stresses on the external magnetic field configuration and Ha are displayed in Figure 11. As Ha increases, the shear stress on the inner cylinder always increases but that on the outer cylinder does not necessarily follows this rule. In fact, the formation of the recirculation cell in the region without external magnetic field serves to reverse the shear stress the outer cylinder surface experiences. For this reason, it is found there exists a critical reference Hartmann number beyond which the shear stress on the outer cylinder acts on the opposite direction if only an external magnetic field is applied to a quarter of the annular space. Not only so, whenever the external magnetic field covers less than half of the annular space, the magnitude of the shear stress on the outer cylinder will tends to decreases and will eventually replaced by a growing shear stress in the opposite sense if the Hartman number is large enough. Also in these figures, the effect of splitting and separating the external magnetic field on the shear stress on the inner and outer cylinders is investigated. The shear stress associated with the semicircular magnetic field is found to increase in magnitude on the inner cylinder but to decrease in magnitude on the outer one as it is split to form two quarter-circular magnetic field (represented by the broken lines). As the Hartmann number is increases, this magnitude continues to reduce to zero. Then, a shear stress in the opposite sense is anticipated to grow in magnitude. Again, this is strictly related to the nature of the recirculation cells. As the magnetic field is split, the recirculation cell corresponding to the semicircular magnetic field is also split to form two weaker recirculation cells. Because of the presence of these two recirculation cells, the shear flow next to the inner cylinder is more difficult to squeeze through the annular space leading to an increase in shear stress magnitude. On the other hand, the two weaker recirculation cells exert greater reversed friction force and therefore reduce the magnitude of the shear stress on the outer cylinder.
Variation of dimensionless shear stress on cylindrical surface: (a) inner and (b) outer.
A computational study of magnetic fluid in an annular space subjected to a rotating inner cylinder and nonuniform external magnetic fields is accomplished in this work. Based on current investigation, the following conclusions can be drawn.(1)The presence and absence of the external magnetic field brake the fluid elements prior to entering the region with external magnetic field. This leads to the generation of a recirculation cell.(2)In the annular space, a recirculation cell always occupies every discrete region without external magnetic field.(3)The strength and size of the recirculation cell depend on the strength of the external magnetic field, the number of discrete regions without external magnetic field, and their span.(4)The strength of the recirculation cell is inversely proportional to the span in the angular direction of the region subjected to external magnetic field.(5)The shear stress on the moving inner cylinder increases with the reference Hartmann number and the span of the single external magnetic field region.(6)The magnitude of the shear stress on the stationary outer cylinder may increase or decrease with the reference Hartmann number depending on the external magnetic field configuration.(7)Splitting and separating an external magnetic field may cause the magnitude of the shear stress on the moving inner cylinder to increase but that on the stationary outer cylinder to decrease.

The police bodyguard who had an affair with Mayor Megan Barry will get a $6,691 monthly pension, an amount which increased substantially because of the overtime he was paid.
In retirement, Sgt. Rob Forrest would get $80,302.56 a year. That amount could fluctuate if he takes an upfront partial lump-sum payment, according to human resources records.
Forrest, who retired Jan. 31 after 31 years and 3 months with the department, has applied for his pension, according to Metro Human Resources. The Employee Benefits Board still needs to give its approval.
One longtime employee benefits board member said under Nashville law, if any of the ongoing investigations reveal he collected overtime illegally, then Forrest's pension may be reduced.
The pension formula used by the city averages all income over the five-year period during which an employee earned the most money. A police officer's pension is 2 percent times the five-year earnings average for up to 25 years of service. For officers with more than 25 years of service, the calculation includes an additional 1.75 percent times the average five-year earnings average for each additional year.
In addition to his base salary of about $84,000 over his last five years on the job, Forrest regularly earned overtime pay under Mayor Karl Dean and Barry.
Forrest's overtime increased substantially under Barry. He earned $75,462 in overtime pay for fiscal year 2017, and $59,578 in overtime pay for fiscal year 2016 during Barry's tenure.
Forrest earned $35,747 from overtime in fiscal year 2015, $31,748 in fiscal year 2014 and $34,186 for fiscal year 2013 when Dean was mayor.
As Forrest's overtime increased, so did the monthly pension he is eligible to earn.
According to records obtained by The Tennessean, the Human Resources Department sent Forrest a letter estimating a $6,691 monthly pension as of Jan. 31.

By comparison, a similar letter Dec. 31, 2016 — about one year earlier — estimated his monthly pension at $6,003. The July 22, 2015 monthly pension estimate for Forrest was $5,184.
Forrest's monthly pension estimate rose by $1,507 in those two and a half years.
Barry, a Democrat, and Forrest traveled alone on 10 trips in 2016 and 2017. Forrest was there to provide security and Barry said the trips were for city business.
The Tennessee Bureau of Investigation has launched an investigation into the affair between Barry and Forrest, who are both married. Metro Council has approved a special committee to investigate public money spent on travel and overtime expenses. On Wednesday, a complaint was filed with the Metro Board of Ethical Conduct.
"I would imagine what would happen is if any of these investigations going on determined that money was earned illegally, then we would go back and modify his pension," said B.R. Hall, who has served on the employee benefits board since 1985.

An error was encountered: The license key and email does not seem to be valid. Please contact ClickCartPro at www.clickcartpro.co.uk to resolve this issue.
Check that you are using the correct email address for the license key, in the private directory check the config.php this contains the license key and email used to register.
I've checked and used copy/paste, still receive the same message.
For what it's worth sometimes copy paste inadvertently introduces a white space and tha will give you an error (I have had that happen to me).
If you copy and paste make sure there is no space before or after the word/s you just pasted.
Thank-you for correcting the problem but now I have another!
I am running the installer and cannot get past the password.
and have no idea what the password is and don't understand "If you do not remember the installer password you selected during the initial installation of this program, edit the 'config.php' file in this directory. Delete the MD5 hash assigned to the 'khxc.password' variable to create a new password."
Why can't anything in this program work first time or even be explained without the use of jargon?
Sorry to sound frustrated it is just that I am!
What you can do is remove the password from the config.php file.
"Thank you. The database was fully up to date. No changes were made."

Today, we have access to data in so many places. Databases, local files, but it doesn't end there. What about the rise of thousands of online services? Think of your CRM, accounting software, social media accounts, and so on. They contain tons of interesting data inside the application itself. But how to combine all these fragmented data into a single source? Meet your savior: Cumul.io plugins!
Most BI tools offer an easy connection to a number of databases and online services like Salesforce, Google Analytics, SQL Server,… However, you could be using an online service that isn't available by default in any existing BI tool. This is where Cumul.io plugins step in!
Build integrations to any data source. Even if you're using a very niche online service or a custom database, you'll be able to connect to it with a plugin.
Quick & easy to build. We made plugins as easy as possible to build. Typically, you'll need less than 100 lines of code in total. After set-up, you'll be able to connect whenever, wherever, without any further coding.
Build as many plugins as you like. Connect to 1 data source? 20 data sources? You can build a plugin for each single one of them. Keep that data richness growing!
So first, what is a plugin? It's a flexible 'data adapter' between Cumul.io on the one hand, and the data source of your choice on the other hand. It's an easy way to let data flow from 1 source into Cumul.io in real-time, without wasting hours on custom development, but with great data security.
And now, how to connect to a source? You'll only need some help from a developer to build the plugin. But thanks to the flexible plugin structure and documentation, this is very easy to build in less than 100 lines of code. Once you've built the plugin, you can connect to the data source just like any other default one in Cumul.io. Data will always be up-to-date.
To give you a better idea of how plugins work, we've created an example plugin with Citybik.es. This open data initiative gathers data of bike sharing systems worldwide. Data is available through a public API, to which we connect through a Cumul.io plugin.
Citybikes is publically available (go look for it in your account!) since the data is useful to anyone. However, the general settings in Cumul.io will publish your plugin privately, for internal use only. Easily switch between options.
Data privacy & authentication is secured as you wish. Additionally, no data will be stored in Cumul.io when using the plugin structure. It will only work as a means to let the data flow through.
Connect to Citybik.es just like you would connect to Teamleader or Google Analytics. Pick a city, and start visualizing the data! Get inspired to build your own data plugin!

Q: Add a column at the end of file with a value for certain number of rows I have a text file and I want to add a new column at the end with the value '0' for the first 2000 rows and '1' for the next 3000 rows.
A code using awk or shell or sed will be suitable.

A: Something like can do the work:
awk '{ if (NR<=2000) print $0,0; else if (NR<=5000 ) print $0,1; }' input_filename

Of course you can change the delimiter if need
if you need to print also all the lines after 5000 you can use code like this:
 awk '{ if (NR<=2000) print $0,0; else if (NR<=5000 ) print $0,1; else print }'

A: A short awk
awk '$0=$0(NR<2001?" 0":" 1")' file

This will add 0 for the first 2000 rows and 1 for the rest.
It you like to stop at 5000
awk '$0=$0(NR<2001?" 0":(NR<5001?" 1":""))' file

A: give this one-liner a try:
awk 'NR<2001{$(NF+1)=0;print;next}NR<5001{$(NF+1)=1}7' file

Community residents were asked if they really understood why diversity, inclusion, racial justice and equity are important to a community during a session sponsored by The United Way of Bartholomew County, along with several other organizations.
The event, "Understanding and Building Equity in Community," was at The Commons in downtown Columbus Thursday presented by the National Equity Project, an Oakland, California-based non-profit that seeks to help communities achieve equity for historically under-served populations through education. About 100 community leaders, city officials and local activists attended.
