![]() ![]() Maybe 98 lives might have been saved in the implosion of the 12-story Champlain Towers South if, as engineers had warned years before the tragedy, the abundant cracking in the 40-year-old structure from the damaged, exposed and rusting rebar had been replaced by Basanite’s rebar that doesn’t rust. I say it’s a good start, but I’d take it a few giant steps further by encouraging greater use of BasaFlex, a rust-proof building material made by Basanitein Pompano Beach, Florida and another green product made by A Fiberglass Solutionin nearby South Carolina whose maintenance free fiberglass is another far better solution than wood or steel as it will not rot or rust and lasts 50-plus years with no maintenance. Buildings within three miles of the coastline would be inspected after 20 years and every seven years thereafter. The legislation would require a two-part inspection at these buildings’ 30-year mark and then once every 10 years thereafter. ![]() The proposed legislation (SB 1702) received unanimous approval from the Senate Community Affairs Committee. Recently the first condominium regulation update since the Surfside disaster last year sailed through a Senate committee, aiming to require 30-year-old, multifamily buildings taller than three stories to get inspected. Why do we keep feeding corrosion its favorite food-steel? Why aren’t we using rust-proof rebar made from basalt fiber when there’s a company right in Florida called Basanite Inc (OTCQB:BASA) that manufactures it?Īnd if it’s permanence we want, why are we not building our stairs, doors, windows, railings and even our docks with the same durable, rust-proof material we use to build our boats-fiberglass? What are we, rust fans? Corrosion lovers? I know something about it as I’ve seen it rusting before my own eyes during the periodic balcony restorations that must continually occur in oceanfront properties like mine when rusting rebar hemorrhages causing noticeable cracks in the cement. Many believe it’s resulting from a ubiquitous building material called steel rebar that’s rusting everywhere it’s used in construction throughout the state. Today it’s a different type of rust belt occurring in communities along Florida’s beautiful and captivating oceanfront. The Rust Belt used to be a region of the Northeastern and Midwestern United States experiencing industrial decline starting around 1980 with the transfer of manufacturing jobs overseas, increased automation, and the decline of the US steel and coal industries. ![]()

![]() ![]() Bombsicle: If you’ve ever had a bomb pop, then you’ll immediately recognize this one.Mango Peach is also not too sweet, and it’s a flavor I regularly order. Mango Peach: This is one of the most natural flavors that Gorilla Mind has created, and you get a nice taste of these two fruits.I also find that incredibly feels natural, as if you’d mixed some fresh fruit juices. Volcano Burst: This combines tropical orange, mango, and pineapple, and it’s a great balance of sweet and sour.It’s refreshing enough and not too sweet. ![]() Mojo Mojito: This is an interesting one as it’s a less bitter version of lemon-lime with a bit of a hint of mint.It has a great combination of different fruits but is a bit sweeter tasting than most of the others. Fruit Punch: If you tend to prefer sweet-flavored solid pre-workouts, then this is probably your best option.You can barely taste the peach, but it provides enough sweetness to avoid it being too tangy. Firefly Lemonade: This is a combination of peach and lemonade, and it’s a great balance between sweet and bitter.But I would say that you have to like coconut flavor as it’s quite strong. Tiger’s Blood: This is a mix of strawberry, watermelon, and coconut, and it’s the one I order most often.You can read our other article if you're after a pre-workout without creatine.īut let’s take a closer look at all of the Gorilla Mode flavors available right now: Within just a month, I did notice a massive increase in strength as I was able to add more weights to my deadlifts and bench press. Ī daily dose of 3 to 5 g of creatine is effective in maintaining creatine stores. The ingredient's effect is owed to its ability to increase phosphocreatine stores in the body, which is used during intense workouts to produce ATP. Studies have shown that it can impact muscle strength and muscle size, so if you’re looking for a serious pump, you shouldn’t be using a pre-workout with it. Unlike Gorilla Mode, which is a popular pre-workout supplement known for its significant boost in focus and energy levels, creatine monohydrate is an amino acid that is commonly used in workout routines to enhance performance.Ĭreatine is the go-to ingredient to enhance physical performance. I had an insane performance at the gym with improved pumps and increased muscle strength and muscular endurance. I’m quite impressed with how generous the Gorilla Mode pre-workout creators were with the amount of L-citrulline, which is more than other good pre-workout products in the market. ![]() ![]() Directly export downloaded videos and songs to iTunes.Download annotations and subtitles in. ![]() With this freeware, you can download videos in HD 1080p, HD 720p, 4K, and 8K resolution and enjoy these high definition videos on your HD TV, iPhone, iPad, Samsung Galaxy and other devices.

For instance, the Luminous Flux for a 100W incandescent lamp is approximately 1700 lm. It is commonly given for a lamp based on laboratory testing during manufacture. Generally, it is not necessary to determine the luminous flux for yourself. This makes it easier to determine the Luminous Flux of this lamp versus the incandescent. It emits radiant flux at 6 primary wavelengths. Mercury emits light primarily in a line spectrum. For sources like a mercury vapor lamp, however, it is slightly easier. A standard incandescent lamp produces a continuous spectrum in the visible, and various intervals must be used to determine the Luminous Flux. Some sources are easier to do this with than others. Adding up the flux at each wavelength gives a total flux produced by a source in the visible spectrum. Once that is done, it is necessary to calculate the Luminous Flux at each wavelength, or at regular intervals for continuous spectra. It is necessary to determine the Spectral Power Distribution for the particular source. 905 lm, a significantly greater power output.ĭetermining the Luminous Flux from a source radiating over a spectrum is more difficult. While a 5 mW laser pointer at 630 nm produces The Luminous Flux from a monochromatic source producing light at a single wavelength is easiest to determine.įor instance, a 5 mW laser pointer using at a wavelength of 680 nm produces. Since the eye does not see all wavelengths equally well, the efficacy curve is a very important way to determine the Luminous Flux from a source. 1 lumen is defined to be 1/4 p candela, the SI base unit of Luminous Intensity. The lumen is the unit of luminous flux, and is defined in terms of the candela, an SI base unit like the meter or second. In the photopic region, the peak at 555 nm is assigned a conversion value of 683 lumens per Watt. This weighting factor, or luminous efficacy (V l), allows for conversion of Radiant Flux to Luminous Flux at any wavelength. The eye's nighttime sensitivity, called scotopic vision, shifts toward the blue end of the visible, peaking at 507 nm and falling to 10 -4 at 340 and 670 nm. This constitutes the range of daylight sensitivity, or photopic vision. The sensitivity of the eye peaks at 555 nm and falls off to approximately 10 -4 at 380 and 750 nm. It is a weighted average because the human eye does not respond equally to all visible wavelengths. ![]() Thus, luminous flux is a weighted average of the Radiant Flux in the visible spectrum. More specifically, it is energy radiated over wavelengths sensitive to the human eye, from about 330 nm to 780 nm. Luminous Flux ( F v) is energy per unit time (dQ/dt) that is radiated from a source over visible wavelengths. Units for other quantities in photometry contain the lumen, such as the lux (lumens/meter 2) Comparison of luminous performance of light sources ![]() The luminous efficacy is 1 at that frequency.Ī typical 100 watt incandescent bulb has a luminous flux of about 1700 lumens. The luminous flux is the part of the power which is perceived as light by the human eye, and the figure 683 lumens/watt is based upon the sensitivity of the eye at 555 nm, the peak efficiency of the photopic (daylight) vision curve. Luminous flux in lumens = Radiant power (watts) x 683 lumens/watt x luminous efficacy In terms of radiant power (also called radiant flux) it can be expressed as: The abbreviation is lm and the symbol is F v. It can be defined as the luminous flux emitted into unit solid angle (1 sr) by an isotropic point source having a luminous intensity of 1 candela. It is an SI derived unit based on the candela. The lumen is the standard unit for the luminous flux of a light source. The standard definition is as follows: Radiometry and photometry This power must be factored by the sensitivity of the human eye to determine luminous flux in lumens. ![]() The radiant power is the total radiated power in watts, also called radiant flux. ![]() ![]() ![]() ![]() Some of the insurers that mentioned an impact of COVID-19 or ARPA on their 2022 costs did not specify the factor or redacted the amount.Īmong the 91 insurers that quantified an impact of COVID-19 on their 2022 costs, the impact of COVID-19 on 2022 individual market costs ranged from -2.6% to 8.4% with half of insurers falling between no impact and 1.0% increase. Of the 311 insurer rate filings we reviewed across all states and D.C., 91 (29%) quantified a COVID-19 impact on rates in their filings, and 50 filings (16%) quantified an impact of ARPA expanded subsidies on 2022 rates. We also reviewed rate filings for the impact of the American Rescue Plan Act (ARPA), which expanded subsidies available in the ACA health insurance Marketplaces, on 2022 average costs in the individual market. Although the Affordable Care Act (ACA) individual market represents a small share of the privately insured population, the rate filings for this market are detailed and publicly accessible, making them a useful source of information on how health insurers are thinking about their likely costs for the next year. In this brief, we reviewed final 2022 premium rate filings for Marketplace-participating individual market insurers in all 50 states and the District of Columbia. Rates are finalized in early fall (October 15, 2021) ahead of the annual open enrollment period, set to begin on November 1, 2021. Insurers planning to offer health plans on the Affordable Care Act (ACA) Marketplaces must submit filings to state or federal regulators detailing their plan offerings and justifying their premiums for the upcoming year. Reviewing health insurer premium calculations for the coming year can give us a glimpse into how the pandemic may or may not affect health spending and utilization in the future. While uncertainty around the pandemic’s effect on health spending remains, health insurance actuaries have access to the latest health utilization and spending data and can use these data to model future trends. However, for physician services, outpatient care centers, and hospitals, spending in the second quarter of 2021 remained below expected based on pre-pandemic spending. In the second quarter of 2021, actual laboratory services revenue was somewhat above expectations based on pre-pandemic spending, likely due to increased use of COVID-19 testing services. Projected revenues were estimated based on 2018 second quarter to 2019 second quarter revenue growth rate applied to the 2019 second quarter forward to 2021. ![]() Census Bureau’s Quarterly Services Survey (QSS) data show seasonally adjusted health services revenue in the second quarter of 2021 remained below projected levels. Health services spending remained below projected levels through the second quarter of 2021 The continued impact of the COVID-19 pandemic may introduce more uncertainty on future health costs. As a result of lagging vaccinations and the more infectious delta variant, COVID-19 hospitalizations and deaths, the overwhelming majority of which are among unvaccinated people, increased over the summer. The effects of this delayed and forgone care on health spending and outcomes are yet to be seen. Thus far into the year, we have not seen pent-up demand from delayed or forgone care in the last year. Utilization of health services has remained somewhat lower than expected based on utilization levels in years before the pandemic. In April 2020, health spending dropped precipitously as providers cancelled elective care and patients practicing social distancing avoided health facilities. The COVID-19 pandemic disrupted health spending and utilization trends in the United States, though it is not yet clear how long that disruption will last. ![]() ![]() ![]() 10, CEO Kwon Young-soo said the company will increase its battery production capacity 2.6 times over three years to 400 gigawatt-hours.

Just as I did with Darryl, I made copies of the passages on colored paper and then affixed them to large sheets of butcher paper. At the end of each period, Emily sent those down to the media center along with a roster of groups she selected to help us organize for Friday. Most students chose something in the middle about a paragraph or so in length. Some students chose brief and specific passages others chose large extended sections spanning 2-3 pages. On Thursday, students used the same template we used with Darryl’s classes to have students identify a passage that stood out to them as well as questions they had about that chunk of text. Emily did this with her three classes at the beginning of the week before coming down to the media center on Friday to do the write around text on text. This can then be followed-up with small group discussion about the ideas and points they wrote on paper before moving to a large group share. Depending on how many people are in a group, this could go back and forth between pairs or you could simply write around the small group until everyone had a chance to respond to each other. You can begin by having students write silently for 3-4 minutes and then swapping letters ( which can be written on notebook paper or large index cards) and writing again for bursts of 3-4 minutes. One of our reflections from our work with Darryl is that we think it would helpful to scaffold the write around text on text strategy by first giving students the opportunity to do the “silent literature circle letters.” In this strategy, students can work in pairs or small groups of 3-4 (no more than 4) to have a conversation about a text or question through timed letter writing. When she came to us for ideas for helping students transact with the text and their peers, we shared some of the strategies from the Daniels workshop as well as the write around text on text strategy we did with Darryl Cicchetti. Emily Russell, a teacher and Language Arts Department Chair we’ve collaborated with regularly this past year, and her students have been reading the memoir The Glass Castle by Jeannette Walls. This past Friday, my fellow librarian Jennifer Lund and I had another opportunity to help facilitate written conversations about texts using the strategies we learned in the Harvey Daniels workshop we attended in December 2013. ![]() ![]() It is easy to see that we can do this for any simple convex polygon. So, the sum of the interior angles in the simple convex pentagon is 5*180°-360°=900°-360° = 540°. How? Since these 5 angles form a perfect circle around the point we selected, we know they sum up to 360°. But the 5 apex angles formed around the point we selected are inside the pentagon, and are not part of the sum of its interior angles - so we need to subtract them. Since we have 5 sides, we will have formed 5 triangles, with each side of the pentagon forming the base of a triangle, and the random interior point we selected forming the apex of each triangle.Įach one of these triangles has a sum of angles of 180°, so 5 of them are 5*180°= 900°. We can represent a regular pentagon as shown below. The day after Elon Musk challenged Mark Zuckerberg on social media to a cage. We will consider the 5 sided regular polygon, that is, a regular pentagon. They have both vowed to work out more frequently in 2023. By using the given information that the exterior angle is 2/3 of the. But this time, I will pick a random point inside the pentagon, and connect it to all the vertices: In this video you will learn about the 5 sided polygon called a Pentagon.A pentagon is a 5 sided polygonA polygon is a closed 2D shape with straight lines. Ryan Mac reports on Twitter and Mike Isaac covers Meta. Since the number of sides must be a whole number, the regular polygon must have 5 sides. I will still use the concept of dividing up the polygon into triangles. A general strategy for solving this problemīut I want to do a slightly different version of this, which is easier to generalize to a polygon of any number of sides. We could repeat this strategy here, partitioning the pentagon into a triangle and a quadrilateral, like so:Īnd now, using the fact the triangle's interior angle sum up to 180°, the sum of the interior angles in a simple convex quadrilateral is 360°, and the angle addition postulate, we can add up all the angles of the triangle and the quadrilateral, and see that the sum of all the interior angles in the simple convex pentagon is 180°+ 360°= 540°. And we have used this to show that the sum of the interior angles in a simple convex quadrilateral is 360°, by partitioning it into two triangles, where the angles of the triangles make up the angles of the quadrilateral: So, a shape is a polygon if it is a simple closed figure made up entirely of straight-line segments. We know that the sum of angles in a triangle is 180°. So, (i), (ii), (iii) ( i), ( i i), ( i i i), and (iv) ( i v) are simple closed curves. Show that the sum of all interior angles in a simple convex pentagon is 540°. ![]() And then we will generalize the proof to get a formula that can be used to find the sum of all interior angles for any simple convex polygon. This season as a starter he has a 5.48 ERA in 21.1 innings of work and as a reliever his ERA is 1.56 in 17.1 innings. Let them practice their shape learning while having loads of fun with colorful graphics and entertaining sounds.In today's geometry lesson, we will show that the sum of the interior angles in a pentagon is 540°. has the best educational tools you will need to help your students learn shapes in both 2D and 3D format. Interior angles measure 1620°.ĭodecagon - 12 sides with 150° angles. Hendecagon - 11 sides with 147.3° angles. Interior angles measure 1260°.ĭecagon - 10 sides with 144° angles. ![]() ![]() Polygons are classified by the number of sides and interior angle measurements. Irregular polygons have the same number of sides as their counterpart but are either concave or convex in shape. They may also explore the difference between regular and irregular polygons. In geometry, a pentagon (from the Greek pente meaning five and gonia meaning angle) is any five-sided polygon or 5-gon. Let us learn more about the pentagon shape, the pentagon properties, pentagon shape objects, and some pentagon shape examples in this article. What do you observe about the opposite sides of trapeziums The arrows show which sides are parallel to each other. This five sided shape has five straight sides and five interior angles, which add up to 540. The sides can be any length however, they must all be equal in order for the shape to be considered a true pentagon. Each angle forms an internal angle of 108°, which means that if you add up all the internal angles they will equal 540°. Students will also begin to identify the difference between larger polygons. The figures in group 5 are called trapeziums. A pentagon is a five-sided polygon, meaning it has five straight sides and five angles. ![]() |
