Old English hara "hare," from West Germanic *hasan- (cf. Old Frisian hasa, Middle Dutch haese, Dutch haas, Old High German haso, German Hase), possibly with a sense of "gray" (cf. Old English hasu, Old High German hasan "gray"), from PIE *kas- "gray" (cf. Latin canus "white, gray, gray-haired"). Perhaps cognate with Sanskrit sasah, Afghan soe, Welsh ceinach "hare." Rabbits burrow in the ground; hares do not. Hare-lip is from 1560s.
þou hast a crokyd tunge heldyng wyth hownd and wyth hare. ["Jacob's Well," c.1440]
"to harry, harass," 1520s; meaning "to frighten" is 1650s; of uncertain origin; connections have been suggested to harry (v.) and to hare (n.). Related: Hared; haring.
(Heb. 'arnebeth) was prohibited as food according to the Mosaic law (Lev. 11:6; Deut. 14:7), "because he cheweth the cud, but divideth not the hoof." The habit of this animal is to grind its teeth and move its jaw as if it actually chewed the cud. But, like the cony (q.v.), it is not a ruminant with four stomachs, but a rodent like the squirrel, rat, etc. Moses speaks of it according to appearance. It is interdicted because, though apparently chewing the cud, it did not divide the hoof. There are two species in Syria, (1) the Lepus Syriacus or Syrian hare, which is like the English hare; and (2) the Lepus Sinaiticus, or hare of the desert. No rabbits are found in Syria.

Scary new research has revealed fertility drugs can more than double the chances of childhood leukemia.
They also had a 2.3 fold increased risk of suffering the rarer form of the disease, acute myeloid leukemia (AML), the researchers claimed.
The findings further revealed that youngsters conceived naturally after women waited over a year to get pregnant had a 50 of all live births in 2007 a result of fertility treatment, compared with just 0.5% in 1992. Despite a significant increase in risk, the actual number of children developing leukemia after their mothers undergo fertility treatment remains very small. Only 400 cases of childhood leukemia are diagnosed in UK each year. Three-quarters of those are acute lymphoblastic leukemia, which is most common in children between the ages of one and four, and affects more boys than girls.
Do reports like this worry you, or do you think any minuscule 'risk' can be whipped up into a scary statistic?

Res publica christiana
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Res publica christiana is a Latin phrase combining the idea of res publica and christiana to describe the worldwide community of Christianity and its well-being. A single English word with somewhat comparable meaning is "Christendom".
This phrase is notably found in the encyclical Christianae Republicae Salus, a Roman Catholic Church document which condemns Voltairian and masonic indifferentism in matters of religion.

History of Albion River Bridge
Posted: 07/09/2014
Albion River Bridge July 2001, shot at the bay side at very low tide
The first permanent bridge that crossed the Albion River was a draw bridge which allowed the logging tugboat "Zenith" access up the river. This bridge was a part of the first county road that connected the lumber towns together. The bridge is long gone now but the wood members of the bridge pillar are still exposed in the South bank across the river. The old county road crossed Albion Flats where the road is today but it no longer has the sawmill at 18 feet above ground covering it.
As traffic increased, the county constructed a new wood bridge that crossed just up river. This bridge is seen in the upper half of the above photograph east of the sawmill. The bridge was 512 feet long and 16 feet wide with no wheel guards on the sides. Two of the three bridge footings were in the water and are still visible in the river east of the campground. In August 1933, the bridge and road became a part of the state highway system, subject to state maintenance. Soon after the state took over the road maintenance, the declared the bridge as badly worn from overloaded traffic and started the design of a replacement bridge. When the state was ready for materials, World War II had started.
A prolonged battle with the War Resources Board ensued over allocation of the needed steel. California finally prevailed and started construction on the existing bridge in 1942. The final plans allowed for just enough steel to reinforce the two concrete pillars and to build the 130 foot long truss between them. The rest of the bridge is specially treated redwood. Specifications for the bridge are 26 feet wide, 969 feet long, and 150 feet above the river.


The Invention Of A Handheld Electric Mixer
1889 Words8 Pages
In the beginning of time mixers were not electrical like they are now a days really easy for people to use. The egg beaters were hand cranked, Hand cranks don't require electricity, there is a handle you hold it with and a little knob that you twist so it could mix the ingredients together. In 1856, a Maryland Tinner named Ralph Collier was the man who invented hand cranked egg beaters. The hand cranked egg beaters were used by hand nothing electrical in them, but a more years went by people started inventing so much more mixers and they were electrical of different kind. A handheld electric mixer is basically an electrical mixer that has a handle and someone holds it while the mixer is mixing the eggs and other things. Mixers are of course something used in the kitchen and only the kitchen. People or chiefs use it for baking because it makes the dough in a better smoother texture than if it was hand mixed. A classical American mixer brand is Dover stamping company, the company bought the patent egg beaters in 1859. An American man named Rufus Eastman invented the first mixer which was in 1885. The first man to invent electric mixer was named Herbert Johnson that was in 1908. His whole idea started from basically watching television, there was a baker who was making dough with a spoon that is how his idea was formed. There were electrical mixers before but they were hand mixers that used electricity. The electric mixes he made were mostly for bakers with experience and

How to Do Archaeology in Space!
Australian space archaeologist Alice Gorman has co-authored a new paper as part of an international collaboration to study the International Space Station.
If you thought archaeology was down-to-Earth, then you would be wrong. An exciting new paper is looking into ways we can conduct archaeological studies of the International Space Station (ISS). Published by Alice Gorman and Justin Walsh, this article details the challenges of studying such an environment, and possible ways that we can adapt current archaeology methods to space.
Associate Prof. Dr. Alice Gorman from Flinders University in Adelaide, also known as Dr. Space Junk on Twitter, said that conducting an archaeological study of the ISS can provide useful information for future space missions.
"The ISS is our only chance in the present to learn something about how space societies constitute and maintain themselves - and looking at the material culture is a big gap in all the research that has been done before. For longer term missions which can't get supplies from Earth, it's going to be really important to understand how people adapt objects to unintended uses when materials are scarce. A big concern is social dynamics in small, enclosed communities. There have been many, many psychological studies, but none so far on how objects can support or undermine social cohesion - anyone who's ever lived in a student share house will get this!" said Gorman.
What is Space Archaeology?
Archaeology is conducted in order to learn more about the things that people do or have done through material culture and remains. When considering archaeology, you may immediately think of stone tools, ancient Egypt, or people generally digging in a pit of dirt.
However, the relatively new field of space archaeology challenges these assumptions about the limits of archaeology. In studying the archaeology of outer space we can try to understand what kind of social and cultural phenomena are occurring, which may help us in planning future missions.
ISS Archaeological Project
This new project from Gorman and Walsh is the first of its kind in conducting an archaeological study of the ISS, which is representative of the current phase of the human exploration of space. The research conducted so far can be found on a dedicated Twitter account, a website (which also has merchandise), and in a new paper.
When asked about the most interesting object on the ISS from an archaeologist's perspective, Gorman said, "I find mundane, everyday objects to be the most interesting - even when I was a terrestrial archaeologist I wasn't very interested in palaces and opulent grave goods. If you look at almost any photo of the interior of the ISS, you'll soon spot my favourite space artefact: the humble ziplock bag. Probably millions of these have been used on the ISS over 20 years! I'm interested in how they are used, discarded, adapted to new uses by the crew".
This latest paper outlines the difficulties in carrying out archaeology in space - namely the multi-million dollar price tag that would be involved to send an archaeologist into space - and how to counteract these obstacles.
A Methodology for Space Archaeology
In their paper, Gorman and Walsh have developed a methodology to conduct archaeological research of outer space. This builds upon the skills and practices utilised by archaeologists on Earth, but is adapted to be better applied to the unique environment of space, and specialised for the ISS. These methods include:
Analysing the many images taken by the crew to draw connections between the crew, spaces, and objects within the ISS
Interviews and questionnaires with crew members
Developing procedures for crew members to conduct archaeological surveys on the ISS on-site themselves
Researching and investigating the cargo that has returned from the ISS
Researching and investing sites on Earth that are related to the ISS, such as launch and development sites
These methods are hoped to bring about a better understanding of the social and cultural patterns and practices aboard the ISS, and therefore provide useful information for planning future missions to outer space.
Gorman said the biggest difference in space archaeology is the use of photography. "Photography is a core archaeological skill - we use photographs to document environments, stratigraphy, artefact characteristics, and spatial layouts. But usually this is to augment the data derived from measuring and recording in the field, whether that's an excavation or survey. For the ISS, photos are our main evidence. We are 'excavating' the images in a sense, looking for repeated associations and patterns over time," she said.
Dr. Space Junk
This is far from the first time that Alice Gorman has contributed to the field of space archaeology. Last year, Alice released a book about space archaeology called "Dr Space Junk vs the Universe", where she talks about her journey to space archaeology, zip-ties, and the sources of cultural material scattered throughout our solar system. Earlier this year, in the midst of the COVID lockdowns, Alice also produced a twitter course about space archaeology, its history, and its use.

Battling child abuse
Organizations across the country are taking action in the aftermath of the Pennsylvania State University sex scandal.
One such organization, the Chicago Children's Advocacy Center, is attempting to raise awareness of how to prevent child sexual abuse. The nonprofit organization is conducting bi-monthly media receptions in hopes of gaining support for CCAC's mission.
The Penn State scandal has reminded people that sexual abuse against kids is not unusual, and that perpetrators are commonly people who have a close relationship with the child, such as a neighbor or family member, said CCAC's Executive Director Char Rivette.
"I don't want people to be afraid of everybody, but you do have to make sure your kids feel 100 percent comfortable telling you anything about what's going on in their lives," Rivette said. "This is a teachable moment."
According to a report study distributed by CCAC, there were 19,699 reports of abuse in Chicago last year and the numbers remain consistently high, Rivette said.
This year, the organization has had a 20 percent increase in the number of children in need of help. It has not been confirmed whether the rise in reported sexual abuse cases is because of increased awareness of the issue or if it is simply a blip, so workers plan to keep a close eye on the trend, Rivette said.
It can be difficult to recognize when a child has undergone sexual abuse, according to Rivette. The signs vary from child to child.
Typical things to look for include changes in behavioral patterns. If a child begins to act anxious, develops unusual fears, displays changes in sleeping patterns or acts in ways that are not age appropriate, it is time to start asking questions, Rivette said.
"Ask kids questions when [they] start to talk about things, like secrets and special relationships with certain adults and alone time with adults [who] aren't their parents," Rivette said.
Sometimes kids refrain from telling an adult because they fear that no one will believe them, as proven by the length of time it took for the Penn State case to reach authorities.
Stop It Now! is another resource for reporting sexual abuse. The nationwide organization distributes information and guidance to adults so that they can effectively help others confronted with sexual abuse.
According to Deborah Donovan Rice, executive director of Stop It Now, people sometimes report abuse that happened up to 30 years ago.
"We have a lot of people who call us and tell us that this is the first time that they had ever talked to anybody about having been abused," Rice said. "For the first time, they get unconditional support for what they went through and get to hear about resources that could possibly be helpful in dealing with the aftereffects of having been sexually abused."
This year marks the CCAC's 10th anniversary of providing services to Chicago-area children who were sexually abused and their families. Founded by former mayor Richard M. Daley in 1998, the organization opened its doors in 2001 to provide a coordinated investigation of abuse reports, as well as medical examinations, mental health services, referrals to other services and general support.
In the past, abused children were forced to relive what happened to them multiple times while telling their story to parents, social workers, police, investigators, doctors and counselors.
CCAC simplified the process by coordinating forensic interviews with the child and a medical exam in a single location to put the kids at ease, Rivette said.
Ana Correa, CCAC family advocate manager, works directly with the kids to ensure that they are comfortable and understand what is going on.
Some kids come in feeling like they are in trouble while parents come in feeling like they did not do enough to protect their kids, Correa said. "They are in a better place by the time they leave," she said.
If you see any signs of possible abuse, call the Chicago Police Department or the Child Abuse Hotline at _PHONE_. CCAC receives every allegation of sexual abuse in the city.

2nd International Conference on Strategies and Implication for Education and Technological Advancement
Road construction materials and vehicular emissions have been found to constitute the major sources of soil and air pollution. This study attempts to investigate the influence of road furniture and vehicular emissions on the accumulation of heavy metal in some of the roadside soil of Benin City, Edo State. The objective of this study was to determine the concentration of heavy metals such as Zn, Pb, Mn, Cr, Cd, Cu, and Ni from roadside soil around some selected roads in Benin City. Three locations were selected on the basis of their high concentration of vehicular traffic. A control site with no form of vehicular emission or road construction material pollution was selected outside these three locations. Samples were collected from April to June 2013. The concentrations of seven heavy metals in the samples were determined with an atomic absorption spectrometer, of which the result obtained indicates that the metals from the three sampled sites were higher than that in the control site, whereas the mean concentration of each of the heavy metal in the three locations except for Zinc and Nickel was below the European Union Regulatory Standard (EURS). Although these concentrations were below the European Union Regulatory Standard, these metals, which over time are washed by erosion into the local areas used for farming, may pose health hazards. The enhancement of fuel quality and the adoption of emission standards to mitigate the impact of vehicular emissions on human health should be made mandatory.
Key words: Heavy metals, soil, pollution.

HARD-UP Huddersfield students are forking out high rents for their new homes - yet still getting potential death trap accommodation.
That was the warning today from British Gas officials, anxious to hammer home the safety message.
Research from British Gas and the National Union of Students has shown that, despite landlords demanding rents on a par with those paid by better-off tenants, many students get a raw deal in houses where basic gas safety and other life-saving measures are overlooked.
With students arriving at Huddersfield University this week and many others moving all over the country, safety experts are warning partygoers in privately-rented accommodation to make sure their hangover is from the night before and not the first symptoms of carbon monoxide poisoning.
British Gas is urging all students and their families to follow a simple five-point checklist as soon as they move in.
The latest figures show that student rents have now risen to an average of £206 per month for rooms in shared houses - but higher rents have not led to higher standards of safety or quality.
Chris Bielby, British Gas's head of quality and standards, said: "Despite in many cases paying top-level prices, too many students are still getting bottom-end houses for their money.
"The law on safety checks is there to help save lives. It's unacceptable that they still aren't getting the standard of homes everyone else takes for granted."
Accommodation offices at most universities, including Huddersfield, already carry out checks on the properties they include on their housing lists. But British Gas and the NUS are urging all students to carry out simple checks of their own just to be sure.
1. Check with your landlord that the gas appliances in the property were professionally installed by a CORGI registered installer.
2. Check the property has functional smoke detectors and carbon monoxide detectors.
3. Check with your landlord that the furniture is fire resistant.
4. Check that all electrical appliances have been properly wired and check electrical sockets and switches for signs of burning or scorching.
5. Check that the property seems secure - do the ground floor windows have safety catches? Do the external doors seem solid, for instance?

I have redone this question:
On $\mathbb R^n$ the Carleson Operator if defined by $$Cf(x) = \sup_{R>0} \left \vert \int_{B_R(0)} e^{2\pi i x\cdot \xi} \widehat{f}(\xi) d \xi \right \vert. $$ (In the previous version I had an incorrect version of this written down which lead to some stupid conclusions).
 - For $n=1$ Carleson proved that this operator is strong (p,p) which is equivalent $L^p(\mathbb R)$ convergence of $S_Rf(x)=\int_{B_R(0)} e^{2\pi i x\cdot \xi}\widehat{f}(\xi)d\xi\to f(x)$ as $R\to \infty$. The modern proof uses boundedness of the Hilbert-Transform and the ''translation trick'' $$\chi_{[-r,r]}(\xi)\widehat{f}(\xi) = \widehat{[\frac{i}{2}(m_{-r}H m_r - m_r H m_{-r})f] }(\xi).$$
 - For $n>1$ Fefferman proved (using a Becosivitch set) that the transform $T$ defined by $$ \widehat{Tf}(\xi) = \chi_{B_1(0)}(\xi) \widehat{f}(\xi)$$ is unbounded in $L^p$ for $p\neq 2$. (There is no Hilbert Transform in higher dimensions, these become the Reisz Transform and the ''translation tricks'' to express $S_R$ in terms of the Hilbert Transform don't work).
 - The Bochner-Reisz conjecture is about boundedness of smoothened characteristic functions and an MO question about it can be found here Recent progress on Bochner-Riesz conjecture
I was originally thinking that $Cf(x)$ could be defined easily for locally compact abelian groups and compact groups and that perhaps a ''translation trick'' existed in some generality. This appears to not be the case for two reasons
 1. The second bullet shows that it is not true in $\mathbb{R}^n$ for $n>1$.
 2. The third bullet shows you that multiplier operator in $\mathbb{R}^n$ are delicate which makes the definition of a Carleson operator for general abelian groups difficult.
Is the operator $$Cf(x) = \sup_{n\geq 0} \left \vert \int_{\frac{1}{p^n}\mathbb{Z}_p} e^{2\pi i \lbrace x \xi\rbrace } \widehat{f}(\xi) d \mu(\xi) \right \vert. $$ bounded as an operator $L^r(\mathbb Q_p) \to L^r(\mathbb Q_p)$. (I think one can define a similar operator on the Adeles no?). How does smoothness of multipliers effect the problem in more general groups?
I'll make it a community wiki so people can fix it if it has errors.

There is a p-adic analogue of Carleson's theorem. This was worked out by Hunt and Taibleson and you can find an exposition in Taibleson's book "Fourier analysis on local fields". (NB Taibleson did a lot of work extending Euclidean harmonic analysis results such as Carleson's theorem and boundedness of singular integrals to local fields.) I don't know if an adelic Carleson's theorem has been worked out.
The notion of smoothness in the p-adics is different than in real spaces since the p-adics are totally disconnected. Instead of say differentiability (which can be defined at least formally), one looks at locally constant functions. For more general groups, you need to have an appropriate notion(s) of smoothness to ask how changing the smoothness affects your problem.
share|improve this answer
Assuming your question is actually about Carleson's theorem:
Carleson's theorem about the pointwise convergence of Fourier series is really a one-dimensional statement. It makes use of the fact that one can write the (symmetric) partial sum operators in terms of the Hilbert transform. After some manipulations, one arrives at showing that the maximal operator
$\displaystyle\sup_{N\in\mathbb{R}}\left|\int\textrm{signum}(\xi-N)\hat{f}e^{2\pi ix\xi}d\xi\right|$
is bounded from $L^2(\mathbb{R})$ to itself (or weak $L^2$), where the signum function simply outputs the sign of the input. Indeed, proving this operator is bounded is quite difficult, and Carleson's proof has not been drastically simplified in the last 55 years, although I admit this is hearsay as I have never read Carleson's original proof.
If one moves from the line to the plane, how does one change the signum function? Does it become the characteristic function of some half-space? Can the set of discontinuities be the intersection of two lines? Can it be curved? These variations of the problem can drastically change the answer as well as the difficulty of the problem. For instance the question of whether the partial sums of the Fourier series of a function on the 2-torus converges pointwise is a bit more delicate: if you take the sum over bigger and bigger squares in $\mathbb{Z}^2$, the answer is yes, but if one sums over bigger and bigger discs, the question is open.
The one counterexample to the general trend that things outside of $\mathbb{R}$ are harder (which I know of, anyway) is the finite field variant of the Kakeya conjecture: it eluded harmonic analysts for many years but was recently solved by a graduate student in computer science in about two pages. This was a pretty big deal. So anyway, for your particular problem (if it is actually about Carleson's Theorem), I would be surprised if the answer is known but not the top search on google for 'Carleson's Theorem for Adeles'. The result will almost certainly be group-specific if it is known.

Assay of Aliphatic Phthalates in Polymer Products by Sensitive Polarographic Method: Health and Environmental Issue
A faster, simpler and sensitive method was developed for determination of aliphatic phthalates using differential pulse polarography (DPP) as standard technique. The choice and concentration of base electrolyte, solvent, initial potential, effect of water addition and interference by other phthalates were the main parameters to optimize for enhancement of peak current and to obtain well-defined polarogram with lower background current using 1.3 x 10-4 M di-butyl phthalate (DBP) solution. Best results were obtained in the presence of tetra methyl ammonium bromide (TMAB) as electrolyte in methanol solvent with initial potential, -1.4 V. A linear calibration plot was observed in the range of 3 x 10-7 – 1.6 x 10-4 M DBP solution as aliphatic phthalates with lower detection limit of 5.9 x 10-8 M and linear regression coefficient of 0.9987. The developed polarographic method was successfully applied for analysis of aliphtaic phthalates in various samples of locally available polymer products such as baby toys, nipples, teethers, infusion blood bags and shopping bags. The results of the current method were compared with those obtained by a reported method and good agreement was found between them

From: Doctor Jacques
Subject: Re: Discrete Maths, specifically, relations
Hi John,
Indeed, you cannot assume that p and q are empty. Given any strings a
and b, you have to ask if there exist strings p and q that verify the
relation - these strings will depend on the particular strings a and
We must assume that S is the set of _finite_ strings over the given
alphabet, because, if we allow infinite strings, we can no longer
concatenate them. (What would it mean to write a string at the end of
an infinite string?)
It may be useful to try to see if the relation has an intuitive
meaning. As I explained before, this will not always be the case
(relations can be defined arbitrarily). However, in this case and in
plain English, (a,b) in R means that a is a substring of b. You would
not use that as such in a formal proof (well, maybe...), but it helps
understanding what one is talking about.
Is R reflexive? We must check that, for every string a, we can find
strings p and q such that a = paq. Of course, we may take p and q as
the empty string, and this shows that R is reflexive.
R is not symmetric. To prove it, it is sufficient to exhibit two
strings a and b such that (a,b) is in R and (b,a) is not. We can take,
for example, a = x and b = xy.
To check for transitivity, we assume that R contains (a,b) and (b,c).
This means that there exist strings p,q,r,s such that:
 b = paq
 c = rbs
and we must check that R contains (a,c), i.e. that there exist
strings u and v such that
 c = uav
This is indeed the case, as we can write c = rpaqs, and we can take
u = rp and v = qs.
Let us now check for antisymmetry.
Each string has a length, i.e. an integer >= 0 and equal to the number
of characters in the string.
If R contains (a,b), we have b = paq. This shows that length(b) >=
length(a). More precisely, we can write:
 L(b) = L(paq) = L(p) + L(a) + L(q)
Assume that R contains (a,b) and (b,a), i.e. we have:
 b = paq
 a = rbs
This shows that:
 L(b) = L(p) + L(a) + L(q)
 L(a) = L(r) + L(b) + L(s)
and, adding these relations together:
 0 = L(p) + L(q) + L(r) + L(s)
and, as lengths are non-negative, this shows that all lengths are 0,
i.e. p, q, r, s are empty strings, and a = b.
To summarize, we have shown that, if R contains (a,b) and (b,a), then
a = b; i.e. R is antisymmetric.
Does this make sense?

Distribution and activity of ice wedges across the forest-tundra transition, western arctic Canada
Journal of Geophysical Research: Earth Surface, Volume 119 - Issue 9 p. 2032- 2047
Remote sensing, regional ground temperature and ground ice observations, and numerical simulation were used to investigate the size, distribution, and activity of ice wedges in fine-grained mineral and organic soils across the forest-tundra transition in uplands east of theMackenzie Delta. In the northernmost dwarf-shrub tundra, ice wedge polygons cover up to 40% of the ground surface, with the wedges commonly exceeding 3m in width. The largest ice wedges are in peatlands where thermal contraction cracking occurs more frequently than in nearby hummocky terrain with fine-grained soils. There are fewer ice wedges, rarely exceeding 2m in width, in uplands to the south and none have been found in mineral soils of the tall-shrub tundra, although active icewedges are found there throughout peatlands. In the spruce forest zone, small, relict ice wedges are restricted to peatlands. At tundra sites, winter temperatures at the top of permafrost are lower in organic than mineral soils because of the shallow permafrost table, occurrence of phase change at 0°C, and the relatively high thermal conductivity of icy peat. Due to these factors and the high coefficient of thermal contraction of frozen saturated peat, ice wedge cracking and growth is more common in peatlands than in mineral soil. However, the high latent heat content of saturated organic active layer soils may inhibit freezeback, particularly where thick snow accumulates,making the permafrost and the ice wedges in spruce forest polygonal peatlands susceptible to degradation following alteration of drainage or climate warming.

Purpose: To assess the importance of hypoxia imaging for radiation treatment planning by evaluation of the effectiveness of modulated radiation treatments targeting hypoxia with increased doses. Method and Materials: Starting with a two‐dimensional diffusion model of tissue oxygenation, a planar tumor model was developed to simulate chronic and acute hypoxia as well as oxygenation/reoxygenation effects on the microscopic scale. Tumor cell radiation response was evaluated using linear quadratic model taking into account individual cell oxygenation levels. Cell repopulation/tumor shrinkage was not considered, as to represent a slow‐growing tumor. Using this model, we evaluated the effectiveness of intensity modulated radiation therapy treatments targeting hypoxia with increased radiation doses. We compared different approaches to targeting hypoxia, including fixed dose modulation based on the pre‐treatment imaging of hypoxia and adaptive dose modulation based on interfraction imaging of hypoxia. Furthermore, to study the importance of hypoxia imaging resolution we compared two scenarios: 1. microscopic, where cell‐by‐cell imaging of hypoxia and dose delivery is possible, 2. macroscopic, where both imaging and irradiation can be conducted with 1mm resolution. Results: For a total tumor dose of 30Gy, the adaptive hypoxia‐targeting therapy provided the best tumor control for the microscopic scenario with [formula omitted] compared to [formula omitted] for the treatment with uniform dose of 2Gy per fraction. However, for a more realistic macroscopic scenario, the finite resolution of hypoxia imaging and dose delivery significantly reduced the therapeutic advantage of adaptive hypoxia targeted therapy resulting in [formula omitted] compared to 7.09⋅10−5 for the uniform dose treatment. Conclusion: We have demonstrated that the adaptive dose modulation based on oxygenation map acquired before each fraction does results in slightly better tumor control compared to uniform dose delivery. However, the tumor control improvement is yet to be proven significant enough to justify the clinical implementation of hypoxia‐targeting dose modulation.

Remove any leaves from the bottom of the stem that will fall below the water line, cut stems under water and place in fresh water with flower food.
History and Usage:
A member of the Caryophyllaceae (pink) family, sweet William originated in southern Europe. Its botanical name comes from the word "di" which is Greek for of Zeus or Jove and "anthos" which is Greek for flower. There are various stories that attempt to explain how it got its popular name. One story states that the name came from the word "oeillet" which is French for eye. This is in reference to the eye of the flower, which is often a different color than the petals. It was then shortened to "Willy" and then in English, William. Another explanation states that it is named that in honor of St. William or William Shakespeare.
Points of Interest:
Relatives of sweet William include carnation, babies breath, silene, chickweed and snow-in-summer. To Victorians, sweet william represents childhood, memory, gallantry, finesse and dexterity.

Christopher Ross is a New York sculptor whose work synthesizes sculpture techniques with contemporary influences. Commanding and curvaceous, his sculptures frequently reference the heroic female form and are informed by his interest in European art, historical research, and the relationship between male and female.
A horse head with its mouth agape and eyes wide open as if in full stride is the latest example of wearable works of art by the accomplished and prominent sculptor Christopher Ross. Available in exquisitely crafted sterling or gold, it is an Objet d'art or 'body armor', sculpted to be worn on an artisan made belt of walnut brown calfskin.
Christopher Ross envisioned sculpture to wear; works that exist between sculpture and bodily adornment. Each limited edition object is sculpted and finished from A-Z by Mr. Ross himself; numbered, signed and stamped with his signature thumbprint, date and copyright.
Notable collectors include The State Hermitage Museum, Saint Petersburg, Russia; The Metropolitan Museum of Art, New York City and The National Museum of Scotland, Edinburgh.
His sculptures to wear are eye-catching and unmistakable expressions of individuality and discerning taste.

- a reformed calendar officially introduced by the French Republican government on October 5, 1793.
The calendar was taken to have started on the equinox of September 22, 1792, the day of the proclamation of the Republic. It had twelve months of thirty days each, with five days of festivals at the year's end (six in leap years). The names of the months were Vendémiaire, Brumaire, Frimaire, Nivose, Pluviose, Ventose, Germinal, Floréal, Plairial, Messidor, Thermidor, and Fructidor. The new calendar was abandoned under the Napoleonic regime, and the Gregorian calendar was formally reinstated on January 1, 1806


Understanding Catalan's Conjecture
1 mainNumbers are deceptively simple. We use them everyday in a variety of contexts. It's beautiful how there are so many mysteries hidden inside these numbers. Catalan's Conjecture is a mathematical problem that's really easy to understand, but extremely difficult to prove. In fact, it took around 158 years to come up with a mathematical proof. It was Preda Mihăilescu, the amazing Romanian mathematician, who came up with a proof in 2002. In solving these problems, mathematicians come up with profound ideas and formulations that impact many fields within mathematics. Let's go ahead and peel this metaphorical onion, shall we?
What is the conjecture?
This marvelous conjecture was proposed by the Belgian mathematician, Eugène Charles Catalan, back in 1844. It started with the concept of perfect powers. Perfect power refers to a positive integer multiplied by itself a certain number of times. For example, 81 is a perfect power because it can be expressed as 34 (3 x 3 x 3 x 3).
These perfect powers don't usually appear consecutively on the number line. This means that if 81 is a perfect power, then it is very unlikely that 80 or 82 would also be a perfect power. Now being the curious cat that Catalan is, he asked the question — How unlikely is it? The more he thought about it, the more he realized that this is extremely unlikely. In fact, he said that it is so unlikely that 8 (23) and 9 (32) are the only consecutive perfect powers to exist on the number line. This is a pretty powerful statement!
What does it actually look like?
If you are feeling a bit mathematical, then Catalan's Conjecture says that the only solution to the following equation:
am - bn = 1
for a, b > 1 and m, n > 0
is the following set of values:
a = 3, m = 2, b = 2, n = 3
Just for fun, you can try to see out if you can find any other numbers that can be a solution here. Spoiler alert, you can't!
How did Mihăilescu prove it?
Since he proved the conjecture, it was renamed from Catalan's Conjecture to Mihăilescu Theorem. Quite an honor! He used deep theoretical results from cyclotomic fields to prove it. What exactly are cyclotomic fields? A cyclotomic field is a number field with some special properties. A number field is a set of numbers that follow a set of predefined rules. Number fields are used extensively across many branches of mathematics, physics, and engineering.
Now, it's difficult to explain cyclotomic fields in this blog post without discussing the complex roots of unity and talking about the difference between primitive and non-primitive roots. So let's just say that cyclotomic fields are really crucial in number theory because of their properties. He used the properties of cyclotomic fields to prove that 8 and 9 are in fact the only two consecutive perfect powers on the number line.
What's the point of proving it anyway?
Okay he proved the 158 year old conjecture. So what? It's not like we can use it anywhere, right? Well, that's not true. Even though the conjecture looks plain and simple, the underlying mathematics that was employed to prove this conjecture is exquisite. Cyclotomic fields are used extensively in algebraic number theory. A lot of these ideas and tools make their way into engineering, design, and construction of a variety of real world systems. The beauty of number theory is that it embraces almost everyone with welcoming arms, but whispers its elegant secrets to the chosen few.

 1. Nice, there are several other mathematical mysteries which are proved in last 100 years. However, not sure where exactly the catalan's conjecture is used in engineering?

What a great idea; cooking and architecture! How about buying graham crackers and using them as the base. Then buy or make royal icing as glue. Buy different candies for architectural elements; sticks, column, spheres, etc. Have the kids create a 'facade' of a building style. If you are really adventurous, have them do a complete standing building. Build these on cardboard sheets covered with wax paper or aluminum foil. If you are using icing in tubes, the kids could create scroll work with the icing on wax paper and then 'glue' it to the buildings with royal icing.
If all of this is outside of your budget, you can ask the kids to bring either a bag of candy or a tube of icing and then share. Take a tour of the candy isle and let your architectural creativity run wild.
It would be worth buying a box of disposible gloves for the kids, and maybe dress them in aprons.

Subject: Baking Architecture Recipies
Does anyone have any ideas combining architecture and baking?
My 8th graders need to complete an architecture unit, to meet the curriculum. I've introduced them to the three architecture orders of the golden age of Greece, and we've done a photo trip through our town looking at the Greek revival arcitecture, and we've discussed how the ancient Greek architecture has influenced our local architecture.
A large group of 8th graders wants to do a "Art Cooking" project (we have a full size kitchen range in the artroom, and a small fridge) I thought it might be fun to combine cooking with architecture.
Ideas I have not yet boiled down: architectural details in gingerbread, gingerbread houses, etc?
Any other ideas?
Thanks in advance, Mark (who can cook, but isn't a baker)


Field of Dreams is based on three colours, blue, white and black with a closely cropped horizon line, allowing the viewer to gaze over the abstract, somewhat mysterious bent corn stalks into a dreamy and luminous mid-summer sky. Some have likened the shapes of the stalks to cubist works or even many small Sidney Opera Houses, and I can see those comparisons. In addition, if one looks closely at the clouds and blue sky, it is possible to find nearly half of the alphabet's letters in these shapes and forms.
The abstract field, endless sky, and glowing clouds lull one into dreams, hopes, thoughts of the future, reflections on the past and indeed, evaluation of the present. As always, I hope these photographs provide viewers with a mirror into their inner thoughts, hopes, fears, joys, challenges, loves and much more.

If, like me, you don't come from a comp-sci background, then precedence-awareness of operators probably only goes as far as knowing that 3*2+1 means (3*2)+1, and that if you want 3*(2+1), then you'd better damn well say so.
I think putting the addition first (to the left) in your example illustrates the concept of precedence awareness better. Like: 1+3*2 is actually 1+(3*2) and not (1+3)*2.
Second comment: A short paragraph about the C-istic awkward precedence of some operators might be helpful to beginners without a C background. $x == $y & $z
means ($x == $y) & $z
. Enabling warnings catches this btw.

Delayed egress systems are door locking systems which prevent a door from opening immediately when egress is attempted in a non-emergency situation.
One of the golden rules is of course that a lock is never supposed to impede egress, but there are specific situations where it is allowed with special approval from the Local Authority Having Jurisdiction (LAHJ), as long as the application is in accordance with the relevant building code.
Delayed egress has many important uses. For healthcare facilities, it can alert staff to a patient attempting to leave the premises or someone attempting to steal drugs.
In commercial applications, doors may be equipped with delayed egress to discourage shoplifting. At airports, doors leading to hazardous and flight line areas will be equipped with delayed egress.
In schools and childcare, delayed egress systems will deter abductions and delinquency.
In security environments where it is desired that a credential be used for passage in both directions, a delayed egress lock will allow locking of the door, encouraging the use of a credential, without potentially trapping individuals if there is a legitimate reason for them to exit.
It is imperative that the installer confirm the acceptability of a delayed egress system with the LAHJ prior to installation. In some geographical locations, and in some types of occupancies, more than one authority may have jurisdiction, for example a Fire Marshal as well as a Building Inspector. It is the responsibility of the installer to determine the hierarchy of LAHJs for a particular situation, and to take the necessary steps to assure compliance.
Delayed Egress systems are typically configured as:
An integrated Delayed Egress electromagnetic lock in which all logic and locking components are built into a single device
A Component System where locking, logic, annunciation and control devices are separate
A Delayed Egress Exit Device
Depending on the design, the delayed egress may be triggered by door movement or an external triggering device.
Building Codes vary with respect to requirements for Delayed Egress locking arrangements. However they all have a similar set of core safety requirements:
1. The delayed egress lock must be approved or listed and shall be permitted for installation on doors serving occupancy levels as specified per prevailing code (refer to your prevailing code and consult your LAHJ for complete details).
2. The doors must unlock upon activation of an automatic sprinkler system or automatic fire detection system.
3. The door(s) must unlock upon loss of power controlling the delayed egress locking device.
4. The delayed egress locks shall be unlocked by a signal from the fire command center.
Important Note: Some cities may also require a remotely located manual reset station attended at all times by trained personnel. 5. Applying no more than 15 lbs of pressure for a maximum of 1 second (1 second nuisance delay) will start an irreversible process to unlock the door in 15 seconds. The LAHJ may permit up to 30 seconds.
6. An alarm must sound at the opening upon initiation of the release process.
7. A sign must be applied to the door stating, "PUSH UNTIL ALARM SOUNDS. DOOR CAN BE OPENED IN 15 SECONDS.". Letters must be one inch high x 1/8" stroke. The sign shall indicate 30 seconds where applicable.
8. Emergency lighting is required as prescribed per code.
9. The lock must be manually reset at the door.
10. A building occupant may not be required to pass through more than one delayed egress equipped door.
There are differences in the Building Codes as to what types of occupancy a delayed egress system may be installed.
The United State Fire Administration advises: The International Building Code® prohibits delayed egress locks in Group A, E, and H occupancies, while NFPA® 5000, Building Construction and Safety Code allows them in all occupancies except detention and correctional facilities.
Maglocks are relatively inexpensive, work many door and gate types, have no moving parts and are reliable and cost effective.
A healthcare facility was concerned about meeting code requirements but also needed to prevent patients from wandering off in the event of an emergency

Mineralogical Society Distinguished Lecture at NUI Galway
Wednesday, 21 November 2007
'Minerals, metals, molecules and microbes' The Mineralogical Society Distinguished Lecturers programme comes to the Environmental Change Institute, NUI Galway, on Thursday 29 November, with a lecture by Professor David Vaughan of the University of Manchester. Professor Vaughan will deliver a lecture on "Minerals, metals, molecules and microbes: environmental mineralogy and sustainability", at 8pm, with refreshments from 7.30pm, in the Orbsen Building Seminar Room. Environmental mineralogy is the study of minerals with the purpose of understanding and assessing their influence in the movement and fixing of organic and inorganic contaminants at and near the earth's surface. According to Professor David Vaughan, of the University of Manchester, "Metals are critically important both as resources and potential pollutants. Understanding how they can be concentrated or dispersed at the Earth's surface depends on new knowledge, at the molecular scale, of processes involving mineral surfaces, ultrafine particles and mineral-microbe interactions." The lecture will address the following questions: How do we use minerals to contain waste? Can minerals offer green solutions to the problems of waste management? How do minerals assist in the remediation of contaminated soils and waters? How do flora and fauna interact with minerals in rocks and how do they work to break down stone buildings and walls? What are some of the state-of-the-art techniques used to study metal cycling in the environment? Dr. Martin Feely, of the Geofluids Research Group in the Department of Earth and Ocean Sciences at NUI Galway, says that, "On a local level, one of the most visual examples of the importance of mineral-microbe interactions is the manner in which lichen work to degrade Ireland's old stone walls. Understanding how this process occurs is relevant for geologists, archaeologists, environmental consultants, botanists and microbiologists." This lecture is free and open to the public and is hosted by NUI Galway's Environmental Change Institute (ECI) and Department of Earth and Ocean Sciences. For more information please contact _EMAIL_ or phone 091 495061.


Productive Club Helping you follow your dream
From A Weak to Confident Communicator - 30 Day Challenge
Day 11 Challenge: Count how many times you start a sentence with No, But, However
You might think you are approachable and listen to the opinion of others. Little do you know how frequently you disagree or shoot down what others have to say.
You do not have to agree with what every little thing. But when you start your response by disagreement, you push away a person from opening up to you. You have your opinion and he has his, so you can listen to a person without disagreement.
Today, you count the number of times you begin a sentence with any of these 3 words - No, But, However. It does not mean you cannot disagree, but you are not allowed to do that when you begin a sentence. You will be shocked to know how much you disagree with people.

The American Bar Association, as well as many state and local bar associations, are playing a growing role in mainstreaming sustainable development into the practice of law. Our environmental and conservation laws–many of which predate the term "sustainability," are based on recognition that human quality of life and wellbeing depend on the health of their environment and the availability of necessary resources. The implementation and application of these laws, of course, require lawyers. What makes sustainable development distinctive is the idea that decision-making for environmental protection and decision-making for development should be systematically integrated. That often requires actions that go beyond what these laws have required.
Still, a growing number of laws in the United States and around the world reflect this broader understanding. These laws reflect broader global trends: population growth; continuing economic growth; widespread and increasing environmental degradation; including growing greenhouse gas concentrations; a changing climate; and a growing gap between rich and poor that is caused in part by the disparate effects of environmental degradation. These trends, in turn, are driving a number of corporations to design programs to reduce the overall environmental footprint of their operations and to foster a "triple bottom line" (not only profits but also environmental and social benefits).
These programs are increasingly enforced through contracts, and compliance with them is even beginning to be required by legislation. While the U.S. has not adopted comprehensive climate change legislation, there is nonetheless a rapidly evolving law of climate change that combines economic development, job creation, and the reduction of greenhouse gas and other pollutants. In addition, sustainability tools such as ecosystem services, conservation easements, smart growth, and mixed-use development are being increasingly used in the legal system. For these and other reasons, a growing number of lawyers include sustainability in their law practice.
The American Bar Association offers two programs or tools for sustainability in law practice:
- The ABA-EPA Law Office Climate Challenge, a program to encourage law offices to conserve energy and resources, as well as reduce emissions of greenhouse gases and other pollutants.
- The ABA Section on Environment, Energy, and Resources (SEER) Sustainability Framework for Law Organizations, in which a law organization commits to take steps over time toward sustainability.
Both of these programs provide public recognition–on the ABA's website–for participating law organizations. Bar associations in California and Pennsylvania have adopted model sustainability programs for law organizations. Oregon Lawyers for a Sustainable Future has published its own model sustainability policy for law offices. These programs are largely, but not entirely, about law office operations, and are less focused on sustainability counseling and advocacy.
In August 2013, the American Bar Association's House of Delegates adopted its third major resolution on sustainability since 1991. This resolution takes a broader approach. The resolution "urges all governments, lawyers, and ABA entities to act in ways that accelerate progress toward sustainability." The resolution also "encourages law schools, legal education providers, and others concerned with professional development to foster sustainability in their facilities and operations and to help promote a better understanding of the principles of sustainable development in relevant fields of law."
At about the same time this resolution was passed, ABA President James Silkenat appointed a Task Force on Sustainable Development to "focus on ways that the ABA can provide leadership on a national and international basis on sustainable development issues." The Task Force has 20 members, representing government, the private sector, nongovernmental organizations, and academia (including Dernbach).
The Task Force issued its Final Report in 2015. The report provides a detailed description of various sustainable development activities within the ABA. In addition, the Task Force recommended that the ABA strengthen its leadership position on sustainable development, both nationally and internationally. It also identified future issues for discussion–concerning legal education, sustainability in the practice of law, and sustainability in governance. Additional information about the Task Force, as well as sustainability for lawyers, is available here.

A Quick Reference For How To Take A Soil Test
by Marissa Caminiti, UMaine Extension Administrative Specialist, Cumberland County
What does a soil test from the Cooperative Extension do?
A soil test will tell you:
-Nutrient levels in your soil
– Soil pH levels
– Presence of lead contamination, if any
Why should I test my soil?
A soil test will help you to optimize your garden or lawn by providing the information you need to make
your soil healthy for a given crop. Test results also provide recommendations for amendments.
When do I take a soil test?
Soil can be tested any time of year when the ground is not frozen. However, the results of your soil test are
intended to provide recommendations for the following growing season. If you are testing your soil to grow
a garden, then it is most useful to test soil in very early spring, immediately after thaw, or fall in order to
allow time before the growing season begins. You can expect to receive test results in 2-4 weeks.
How do I take a soil test?
We supply soil test kits for free. They come with an order form, instructions, and a collapsible cardboard
box to put your soil sample in. Be sure to read the instruction form carefully. Choose your "analytical
service" and a 3-digit crop code so that you will receive the specific recommendations for your desired
Where do I get a soil test?
There are 3 ways to get a soil test:
1. Visit our office at: 75 Clearwater Drive, Falmouth, ME 04105
2. Call our office at _PHONE_ to request it in the mail
3. Use our online form to order a soil test
How do I mail a soil test?
Mail soil tests to our soil lab in Orono:
Maine Soil Testing Service
5722 Deering Hall
Orono, ME 04469-5722
Include payment for the amount listed for the service(s) you have chosen. In most cases the
standard test, $18 is sufficient for the Home Gardener.
What if I don't understand my soil test results?
When you receive your soil test results, you can call our office _PHONE_ for assistance with interpreting your results and recommendations.


I, holobiont
In 2019, performer and choreographer Nella Turkki and Janis Heldmann created a short choreography for the Urban Art Festival in Herne. The 20-minutes performance named "I, holobiont" dealt with the topic of the human body as a multispecies entity.
A holobiont is a living ecosystem that consists of diverse cells, microbes and bacteria. These living beings share the same body and live in the interdependence of each other. Modern biology claims that the human body is such a system and therefore a holobiont.
How can we encounter the unknown in us and each other, if we are aware that our behavior is influenced by bacteria and microbes? Where are our borders to the environment, if we are not alone in our bodies?
These questions were the main motives of "I, holobiont". Furthermore, a recorded speech invited the audience to discover their own embodied awareness of their holobionic nature.
The performance is abvailable to be shown in festivals in Germany and Europe. The full length video can be requested.


Control.OnManipulationInertiaStarting method
Applies to Windows and Windows Phone
Called before the ManipulationInertiaStarting event occurs.
protected virtual void OnManipulationInertiaStarting(
 ManipulationInertiaStartingRoutedEventArgs e
Type: ManipulationInertiaStartingRoutedEventArgs
Event data for the event.
OnManipulationInertiaStarting represents a prewired event handler for the UIElement.ManipulationInertiaStarting event. Practical controls that derive from Control can override the OnManipulationInertiaStarting method and use this to provide control-specific handling and behavior for that input event. The most common scenario is to use the event handler to mark the event as Handled in the event data. The control code has first chance to handle this event, before any event handlers that are wired on a control instance are invoked. When the event data is marked Handled, then other handlers like those on the control instance won't be called. Also, the event won't bubble. For more info, see the "On* event handler overrides" section in Control.
As it's implemented directly on Control, OnManipulationInertiaStarting has an empty implementation. But each ancestor in a control's hierarchy may have provided an implementation. You won't be able to see this implementation because it's internal native code. In some cases a control will already have existing On* overrides that mark the event Handled. Once you've provided an initial On* override for a control, then any controls that you further derive from your own control class would also inherit the On* overrides you define. Any instances you use have that behavior too.
Note App code can still handle events that may have been marked Handled by a control's On* method logic, but they need to use the handledEventsToo parameter for the UIElement.AddHandler method. For more info, see UIElement.AddHandler or Events and routed events overview.
Windows 8 behavior
Windows 8 doesn't fire ManipulationCompleted in cases where the inertial phase has started (and ManipulationInertiaStarting has fired) but the user has tapped on the item before it's finished scrolling, which cancels the inertial phase visually. The issue is fixed starting with Windows 8.1; ManipulationCompleted is fired as soon as the tap action cancels the inertial phase.
Apps that were compiled for Windows 8 but running on Windows 8.1 continue to use the Windows 8 behavior.

Sugar cane mill is another name for the sugar industry, from which sugar production is carried out. Cane is a cash crop, as is well known. "Effluent treatment plant in sugar industry" Although the biggest industry that contributes to the development of the nation is the sugar industry. However, it is considered to be one of the main sectors that has been listed as a polluting sector. The effluent from the sugar industry is very polluted.
For every tonne of crushed sugar cane produced by the sugar industry, 1,000 L of effluent is produced. If released without treatment, sugar industrial wastewater can pollute both aquatic and terrestrial environments.
Let's talk about effluent treatment plant in sugar industry, in detail.
Sources of effluent in sugar industry
Water splashed to extract the most juice and water used to cool the roller bearings are among the waste products from the sugar industry. Because of the machines and sugar, the mill house waste has a high BOD content. "Effluent treatment plant in sugar industry" The juice filtering cloth has to be cleaned. Despite its tiny volume, the effluent produced in this manner has a significant BOD and suspended particles content.
Additional waste is also produced as a result of molasses handling as well as juice, syrup, and molasses spills and leakage in various parts. The regular cleaning of the floor adds significantly to the pollutant burden. Despite the fact that these wastes are intermittently emitted and tiny in amount, they have a very high BOD.
Effluent treatment plant for sugar industry
Large-scale water consumption and the production of organic compounds as liquid effluents pose serious environmental issues for the sugarcane processing sector. Due to the environmental issues connected to this activity. The inadequate and careless disposal of this effluent in soils and aquatic bodies has attracted a lot of attention in recent years.
However, an improved water and material economy can help sugar mills, like all other sectors, minimise their pollution output. Therefore, water should be used wisely in effluent treatment plant processes and recycled whenever possible. The steps included in Effluent treatment plant are described as follows:
- Screen chamber cum oil & grease tank: The huge floating objects are removed using the screen chamber (Bar Screen). Untreated wastewater may include paper, big floating particles, and other things. The screening chamber stops these debris from fouling the pumps, impellers, and equipment, as well as from choking the piping system. All of these materials are removed from this chamber using a 10 mm wide by 50 mm deep bar screen that is set with 20 mm between each bar. Frequent cleaning operations are conducted to remove stuck materials. The purpose of the oil and grease chamber is to remove oil and grease from the influent, which can harm the pumping system and jeopardise biological treatments.
- Equalization Tank: Peak daily or wet-weather flow can be temporarily stored in equalization basins. In addition to serving as a temporary holding area for incoming effluent during plant maintenance. Basins also allow for the batch dilution and distribution of toxic or highly concentrated wastes that might otherwise prevent biological secondary treatment (such as portable toilet waste, waste from vehicle holding tanks, and septic tank pumpers). Aerators may also be included in flow equalisation basins, which also often have capabilities for bypass and cleaning and variable discharge control. If the basin is located after screening and grit removal, cleaning might be simpler.
- Mixing Tank: In general, mixing tanks are created by mixing the influent that is kept in the equalization tank. Mechanical stirrers are used to perform the mixing.
- An aerator-equipped aeration tank: A liquid or substance is aerated when air is pumped through it, combined with it, or dissolved in it. As a result, aeration tanks are provided to aerate the effluent so that biological waste treatment can proceed more effectively.
- Clarifier: Clarifiers are sedimentation tanks with mechanical mechanisms for continuously removing sediments that are being deposited. A clarifier is frequently used to remove solid particles or suspended solids from a liquid in order to clarify and/or thicken it. Additionally, sludge is referred to the concentrated pollutants that are released from the tank's bottom, whereas scum refers to contaminants that float to the liquid's surface.
- Drying sludge bed: The settled sludge is dewatered using sludge drying beds. In order to keep the concentration of MLSS in the aeration tank constant. The extra sludge from the clarifier is periodically discharged to sludge drying beds. The drainage lines are located 2.5 to 6 metres apart. The bed should incline at a rate of 1 in 200 towards the discharge end.
The effluent treatment plant's overall performance is quite satisfactory. Additionally, the individual units operate effectively, and their removal efficiencies are acceptable. Therefore, it can be concluded that the effluent treatment plant in sugar industry is operating efficiently. Because the treated effluent complies with the MPCB requirement for discharge in inland surface water. This treatment facility has a strong potential for pH, temperature, TDS, and COD reduction. At the ETP's output, the industry's garden area receives the treated effluent.

Is 2ms Response Time Good for Gaming [A Recommended 144Hz Monitor]
If you are in the market for a gaming monitor, response time and refresh rates are two of the most important things you'd look for. If you've been using a 16ms or 8ms gaming monitor before now, getting anything lower, either a 5ms or 2ms will show a remarkable difference.
But in reality, is 2ms response time good for gaming? I'd be answering that and sharing my top choice when it comes to a gaming monitor that will be providing you top-notch performances.
Yes. A 2ms response time is good for gaming. With a 2ms response time coupled with a decent refresh rate, you will notice a remarkable improvement in the gaming experience, including how smooth, fast, and responsive-to-control your gameplay is.
First, let's begin by talking about what response time is, and just why you'd need to consider the response time of a gaming monitor before you commit.
Response Time Definition in Gaming Performance Testing – What Does 2ms Response Time Mean?
Response time (ms) in gaming is defined as the amount of time it takes from the time a person makes a request or calls a control to the time the request receives a response. It also refers to the speed at which the monitor transits from one color to another and from one shade to another.
Is 1ms Response Time Good for Gaming?
So let's say you are playing a high FPS game. It's expected that the in-game character responds to your command as soon as you hit the specific command. So generally, the lower the response time of a gaming monitor, the better the gaming experience.
The best response time for a gaming monitor is 5ms and below. With 2ms or even 1ms, you are sure to be in the sweet spot. If you have ever had to game with 16ms gaming monitors and then switch to a 5ms gaming monitor, you'll surely see a remarkable improvement.
2ms Response Time Vs. 1ms
A 1ms response time and a 2ms response time are technically the same. While you get similar performances, 1ms response time remains the top option for gamers. And if gamers are using it a lot more, then there's a chance it trumps a 2ms gaming monitor.
2ms and 1ms gaming monitors have almost similar pricing, so if you're in it for a monitor that will last quite some time, then why not just invest in a high-quality 1ms gaming monitor.
2ms Vs. 4ms Response Time
While it doesn't show a remarkable difference unless you're coming from 1ms response time, you should be able to use any of these two and be just fine if you're a casual gamer. You should remember that a 2ms response time is a lot better than a 4ms response time, and you'll always enjoy gaming with a 2ms response time monitor over a 4ms response time monitor if you're a pro gamer.
Response Time Monitor 2ms Vs. 5ms
Generally, I'd not trouble myself with anything from 5ms and below. 5ms is presently the standard for most gaming monitors, with 2ms being the top of the range set. Yes, 2ms vs. 5ms has a noticeable difference, and when gaming with a monitor with a response time of 5ms, you'd sure see a slower response time when compared to a 2ms monitor.
But this is mostly noticed when you deliberately look for the difference, for the most part, most casual gamers get away with 5ms response time monitors.
2ms Vs. 6ms Response Time
6ms response time is too low for most gamers. While most gamers will easily get away with 5ms response time gaming monitors, 6ms is simply stretching things too far. You will surely see a noticeable difference between 2ms and 6ms monitors. Always shoot for 5ms response time and below, better yet, shoot for 2ms and 1ms for optimal performance.
8ms Vs. 2ms Response Time
2ms response time trumps 8ms anytime. If you're serious about gaming and getting the most out of every gaming session, especially if you're into shooter games and others that require high FPS, then a 2ms gaming monitor will improve your efficiency. 8ms response time isn't good enough for games and gaming consoles these days.
2ms Response Time Monitor – Gaming Monitor with 2ms Response Time
If you are looking for a high-quality gaming monitor with 2ms response time, then you should try the ASUS VE248H 24 inches Full HD monitor.
2ms Response Time TV
If you are looking for a high-quality high response time TV for gaming, I will recommend the TCL 55S425 4K TV. You get an amazing refresh rate, amazing response time, and great color and picture quality.
Samsung Monitor 2ms Response Time
If you are looking out for a good Samsung monitor with 2ms response time, either for work or gaming, the Samsung 850 is one of the best options on the market. You get amazing quality, excellent performance for both work and gaming, and a great build.
IPS Monitor 2ms Response Time
The LG 27GL83A-B is one of the best IPS gaming monitors with healthy response time. You don't just get 2ms, you get an amazing deal. A 1ms gaming monitor for the same price you'll find a gaming monitor with 2ms response time.

I ran across Picard categories in a totally different area of mathematics, but maybe it helps.
In short, a Picard category is a group object in the category of groupoids.
Picard categories come up when you study Picard stacks. Roughly, a Picard stack is a sheaf of Picard categories. The classical example is taking a two-term (perfect??) complex of sheaves, and asssociating to such a complex the Groupoid quotient of the one term by the other. This is important when you want to produce a geomteric object from such a complex. This is an important tool in defining virtual fundamental classes as in _URL_
Before I tell you to many things that are not true, here are the references I know of:
Lecture notes of Martin Olsson at _URL_ Lecture 5. You can even watch that on video: _URL_
The definitive reference is Expos'e XVIII of SGA 4. You used to be able to get that at the Grothendieck circle. Now its still availabe on all the usual Russian sites.
And finally there are very friendly and down to earth lectures of Barbara Fanechi Fantechi at _URL_ I think lecture 3 or lecture 4 is about Picard categories.
