The identification and study of design narrative describes a technology driven phenomenon applicable to the past twenty years of technological innovation. As a fusion of principles inherent in dramatic cinema and digital design, the theory has a growing place in the communication of digital and physical design and planning information systems. The basis of design narrative is formulated upon a concept of spatial drama, established within the context of convergence of developing digital communications media.
Narrative, with its progressively broadening range of definitions and even surprising associations, in the past had its strongest association to drama. Cinema, despite its development as a technological medium, has nevertheless certainly incorporated the principles of narrative, of which, drama has historically been a component. Narrative systems are therefore central to and interchangeable with methods for conveyance of dramatic information. This assumption forms the premise of this investigation intending to show that spatial drama, the foundations of which are based upon contrasting values, can be synthesized into digitally designed narrative, particularly within virtual environments and other medial communications platforms. There is the perceived problem with applications of narrative in design, especially concerning digitally designed spatial environments that lack purpose, structure and interest. The resulting narratological model introduces the new concept of spatial drama. Design narrative links spatial narrative to spatial drama for the intentional creation of dramatic contrast within sequential space. This theory contributes to a deeper understanding of spatial issues concerning the use medial technologies.
The virtual learning paradigm produced for Europe's Open University (OU) and the Cambridge Program on Industry (CPI), subsequently demonstrates aspects of the model developed in this investigation. This is accomplished through the depiction of Dr. Charles Hampden-Turner's dilemma theory as both a core concept for the narratological model and OU's distance learning program, Learning and the Connected Economy. Dilemma theory focuses upon opposition and reconciliation of opposing forces. The theory is largely applied to the areas of cross-cultural and organizational behavior. Therefore, the development of a computer-animated graphical portrayal of dilemmas is used to examine spatial drama, within the parameters of the OU's Web-based course, and within the framework of a digitally designed narrative.

Debate at TV Globo prompts 1.64 million tweets, 52% more than the last debate of 2014
Although absent, Bolsonaro was mentioned 563.3 thousand times on Twitter between Wednesday at 10 p.m. and Friday at 1 a.m.; Boulos' statement about the military dictatorship prompted the highest peak of mentions at 10:30 p.m., with 17.7 tweets per minute
Updated 16 de October, 2018 at 10:20 am
The last presidential debate before the first round of the elections at TV Globo saw the absence of Jair Bolsonaro become very relevant on the social networks. Bolsonaro – who granted an interview to TV Record at the same time of the debate – was the presidential hopeful with the most mentions on Twitter during the broadcast of the event, accumulating 563.3 thousand mentions between Wednesday, October 4, at 10 p.m., and Friday, October 5, at 1 a.m., either due to the impact of his interview or due to the debate associated with his opponents. He was far ahead of Ciro Gomes, who registered 455.9 thousand tweets and became the second most mentioned candidate. In total, in this period, we registered 1.64 million references to the seven participants on the social network, as well as Bolsonaro.
Volume of mentions to the presidential hopefuls on Twitter
Fernando Haddad, who is in second place in the opinion polls, was mentioned 266.5 thousand times, behind Guilherme Boulos, whose comment about the military dictatorship represented the peak of political discussion on Twitter: Boulos had 402.1 thousand mentions throughout the debate and, around 10:30 p.m., was responsible for the peak of references to the presidential hopefuls, with an average of 17.7 thousand tweets per minute. In comparison, during the presidential debate at TV Globo in 2014, which happened on October 2, there were 1.08 million tweets in the same period about the participants at the time – therefore, there was an increase of 52% in four years.
The other participants this year were Marina Silva (143.3 thousand tweets), Geraldo Alckmin (91 thousand), Henrique Meirelles (98.7 thousand) and Alvaro Dias (74 thousand). The two initial hours of the confrontation between the candidates coincided with Bolsonaro's interview (which started at 10 p.m.); the political discussion was more intense on the social network during that time, with 1.23 million mentions registered. Towards the end, there was a sharp drop in the volume of interactions among the profiles on Twitter, with Ciro surpassing Bolsonaro as the highlighted candidate between 0:01 a.m. and 1 a.m. this Friday. The Globo broadcast ended at around 0:45 a.m., and there were 660 thousand tweets during the transmission of the debate with the hashtag #debatenaglobo (Debate at Globo), with or without referencing the presidential hopefuls.
Evolution of mentions to the political actors on Twitter
In a debate with low specific impact of public policy topics or agendas, despite the themes that were part of the questions in the event, the search for space between the two extremes that appear to be the favorites for the second round, Haddad and Bolsonaro, set the tone for the discussions between the presidential hopefuls and on the networks, beyond jokes and sarcasm about the candidates and the political scenario. However, economic issues were more emphasized than other topics, with a predominance of associations with Haddad, who brought up acts carried out by the PT administrations and discussed issues focusing on fighting inequality and on labor rights, and with Bolsonaro, who was criticized by his adversaries due to declarations he has given about the theme and for the positions of his VP candidate, general Hamilton Mourão, and of economist Paulo Guedes.

SUPREME SHOWDOWN: Trump Creates CONFIRMATION Team as the Left Vows to Fight
The Trump administration created a "confirmation team" Monday to help the President's Supreme Court nominee make his or her way through Congress as liberal lawmakers vowed to fight the President's pick tooth and nail.
"Teams of attorneys from the White House Counsel's Office and Department of Justice are working to ensure the president has all the information he needs to choose his nominee," White House Press Secretary Sarah Sanders said Monday. "The Department of Justice is fully engaged to support the nomination and confirmation efforts."
The President announced over the weekend his plan to unveil the Supreme Court nominee the first Monday after the Fourth of July holiday weekend, saying "I will be making my choice for Justice of the United States Supreme Court on the first Monday after the July 4th Holiday, July 9th!"
I will be making my choice for Justice of the United States Supreme Court on the first Monday after the July 4th Holiday, July 9th!

Trump's comments come days after multiple liberal legislators pledged to fight the president's pick, with Sen. Cory Booker saying there should be no nominee until after Robert Mueller ends his Russia probe.
BREAKING: Justice ANTHONY KENNEDY to Retire, NEW VACANCY on the Supreme Court
Supreme Court Justice Anthony Kennedy announced Wednesday his plans to retire from the nation's highest court; creating a new vacancy to be filled by President Trump.
Kennedy revealed his decision in a letter delivered to President Trump Wednesday afternoon, saying he was prepared to step down from the court.
"For a member of the legal profession, it is the highest of honors to serve on this Court," he wrote. "Please permit me by this letter to express my profound gratitude for having had the privilege to seek in each case how best to know, interpret and defend the Constitution and the laws that must always conform to its mandates and promises."
"Justice Kennedy, 81, has long been the decisive vote in many closely divided cases. His retirement gives President Trump the opportunity to fundamentally change the course of the Supreme Court," writes the New York Times.

BREAKING: Supreme Court Sides with BAKER Who Refused to Make Same-Sex Wedding Cake
The United States Supreme Court released a highly-anticipated decision Monday morning, siding with a Colorado baker who refused to make a same-sex wedding cake.
In a surprise 7-2 decision, the court discounted an earlier ruling against the baker in a Colorado court, but refused to go so far as to decide the broader issue of whether American businesses have the basic right to refuse service to same-sex couples over religious beliefs.
"The Commission's hostility was inconsistent with the First Amendment's guarantee that our laws be applied in a manner that is neutral toward religion," wrote Justice Kennedy.
The decision went on to say the "broader issue must await further elaboration."
"The reason and motive for the baker's refusal were based on his sincere religious beliefs and convictions. The Court's precedents make clear that the baker, in his capacity as the owner of a business serving the public, might have his right to the free exercise of religion limited by generally applicable laws," Kennedy wrote. "Still, the delicate question of when the free exercise of his religion must yield to an otherwise valid exercise of state power needed to be determined in an adjudication in which religious hostility on the part of the State itself would not be a factor in the balance the State sought to reach."

Teen ISIS recruiter makes bomb threat during online college lecture: feds
The suspect has never been a student at the Houston school, a university rep told The Post on Tuesday.
By Kate Sheehy | New York Post

A teenage ISIS recruiter was busted for making a bomb threat during a live online lecture at the University of Houston in Texas, authorities allege.
Ibraheem Ahmed Al Bayati, 19, Zoom-bombed the college class Sept. 2 — and blurted out in the middle of it, "What does any of this have to do with the fact that UH is about to get bombed in a few days?,'' federal authorities said.
"Gasps from students can be heard after Al Bayati made his proclamation," according to a criminal complaint filed in Texas court last week.
The teen, who identified himself as Abu Qital al Jihadi al Mansur on the call, also said in Arabic the "Islamic State will remain,'' according to the complaint. Prosecutors say the "Islamic State" comment refers to ISIS.
ISIS LAUNCHED MORE THAN 100 ATTACKS IN IRAQ IN AUGUST, A SHARP UPTICK FROM PREVIOUS MONTH
In addition, the suspect held up an index finger, "which is often known as the 'tawheed finger' " — and "sometimes an indicator of radical Islamic ideolog," the document states.
Al Bayati, a US citizen who lives in Richmond outside Houston, was arrested Friday and allegedly later told the feds that his comments were all part of a joke between him and a pal — but officials said the teen is a recruiter for the terror organization.
He consented to a search of his cellphone records, which showed that last October, he told an associate that he "used a certain social media application to find ISIS supporters," the complaint said.
"He then gave an example of where he helped an individual in a certain foreign city, who did not speak Arabic (Al Bayati speaks Arabic), … say the pledge thru voice messages. The 'pledge' appears to be a reference to the pledge potential recruits make when joining ISIS," according to the document.

Then this past May, Al Bayati "reminded [the associate] that he had told him about recruiting ISIS members from a certain foreign city," court docs allege.
"Al Bayati also explained that he was 'literally known' as an ISIS recruiter," the papers state.
"As in most instances of 'Zoom-bombing,' meeting login information was compromised — a student shared the online class link with Al Bayati," the spokeswoman wrote in an email.
Al Bayati is set to appear in court Tuesday afternoon on charges including making a bomb threat.
He faces up to 10 years behind bars if convicted.


North Dakota oil production grew a little less than 10,000 b/d from September to October to set another record with 941,637 b/d.
With current weather conditions, it will take an exceptional November and December for the state to surpass 1 million b/d before year-end. The Bakken has surprised us before, but it looks like it will be some point in the first quarter before North Dakota joins the million barrel a day club.
The state also set a record in October for natural gas production with 1.07 bcf/d and for the number of producing wells with 9,900. With ~200 wells coming online per month, the state will easily surpass 10,000 wells before the end of 2013. Pretty amazing for a state that had just ~3,600 producing wells at the beginning of 2008.

Sometimes idolatry is easy to identify. For instance, when I find myself wanting to be more like my favorite Instagram celebrity than Jesus, I know I am idolizing the Instagram celebrity. Or, when I start prioritizing my body image over my spiritual health and well-being, I know I am idolizing how I look. But idolatry can also be stealthy, especially when it is disguised as piety. This is certainly the case for Micah, his shrines, and his priests.
Micah's story is a slow progression down a dangerous path. It begins with an offering to the Lord—the silver he had stolen from his mother. However, part of the offering is melted down and formed into an idol, something strictly forbidden by Hebrew law (Leviticus 26:1). This idol is then joined by other idols and set up as a shrine in Micah's household. Micah even makes an ephod, which was a garment worn only by priests, and installs one of his sons as a priest to oversee the shrine.
Slowly but surely, we see what Micah is doing: he is turning his home into a tabernacle. The transformation is complete when a young Levite shows up at his door. "Stay with me," invites Micah, "and be my father and priest" (Judges 17:10). And the Levite stays, legitimizing Micah's efforts. Then Micah says, "Now I know that the Lord will be good to me, because a Levite has become my priest" (v.13).
The elements are there—a priest from the appropriate tribe, the priestly garments, an offering of silver to the Lord—but Micah's heart exposes his transactional relationship with God, and these motives reveal his idolatry: Now I know the Lord will be good to me.
Idolatry in the name of the Lord is often the hardest to spot and the most destructive. I can easily idolize my religion over my Savior. I can lose trust in the promise of Christ and begin trusting in my church attendance or how often I volunteer or read Scripture. These rituals in and of themselves are good, but they are meant as an avenue to commune with God, not to be my own god. What often begins as an attempt to be near God can put distance between my heart and His.
Micah did not need to turn his home into a tabernacle and his family into priests, because God was already dwelling among the Israelites. In the same way, I don't have to idolize my religion in an attempt to be nearer to God because He has already come near to me through the person of Jesus Christ, and He remains with me by the Holy Spirit.
Micah's story proves that the line is fine between being active participants in our religion and idolizing it. What starts as piety can quickly slip into idolatry if we're not careful. And in our attempt to be closer to God, we actually end up turning away from true and intimate relationship with Him.
May I heed the warning in Micah's story and honestly examine my heart: Do I worship my religion, or do I worship the Lord, my God?

It has literally taken me 60 years to understand that my relationship with Christ isn't about 'doing', but 'being'. God has been gently, but consistently guiding me along this path.
A year or so ago, someone here told me that I should sit down and have a cup of tea with the Holy Spirit. (I can't remember who said that, but thank you!!!). I now do that very thing. I'm a coffee drinker, but I sit down and literally invite the Holy Spirit to sit with me awhile. We sometimes talk and sometimes just sit here. There are times I feel His presence and sometimes I don't. I don't trust those feelings, but rely on my faith that He is here with me.
Having a relationship with God is freeing to me. It isn't a set of rules and a check list to accomplish. It is a relationship. Sometimes I wander and get distracted, but He always guides me back with open arms. I used to feel like I was such a disappointment to Him when I did that, but I have realized that He knows I'm not perfect and still loves me and wants me.
I sometimes feel a disconnect and I really think I need this alone time as well. Such a great idea! Thank you so much for sharing.
Oh my, this blessed me this morning as much as the teaching on Judges 17!
YES!! Thank you so much for sharing this! For me, it's a daily process of not wandering and instead surrendering to what it is that God is up to, trusting Him and not following anxiety down the treacherous path it takes. Thank you Bessie! This was so good!
Thank you so much for this Bessie!
Thank you for sharing this wisdom.
I'm behind in my reading and don't usually scroll this far into the comments. This touched my heart. Thank you so much!
Reflecting on the question posed by Andrea Lucado ~ "Do I worship my religion, or do I worship the Lord, my God?" I don't think so, but I will reflect on the question much longer.
The James passages are also worthy of reflection. God laid on my heart to think about my thoughts and words. The first day back to school found me failing over and over again. Every day since I have fought diligently against evil thoughts and words that don't honor God. It will be a focus of mine from now on.
Also, fighting discouragement. My husband seems to be doing worse. His speech is slurred at times, his voice weak, he is stumbling and near falling much more frequently. As we were leaving church, a friend called out to me, I stopped, looked at my friend, and we started a conversation. Dennis kept moving and then began to fall. I was always a half an arm's length away and couldn't reach him. He sort of crashed into a brick pillar which kept him from going to the ground. I cried out, my heart pounded, and I was afraid. He was fine and then I sobbed. I have been seeking God's help concerning my contentment and God has helped me! Yesterday's near fall, watching it unfold right in front of me, has had a profound effect on me. Is this my life? Not able to go too many places. Staying close to home. Diligently positioning myself right behind him. Yearning to quit work but out of obedience continuing to work. Sitting in silence. Not being touched. Coming home from school and praying that I won't find him face down in the garage. Heart aching for what we once had and wondering if any of it will be again. We see the neurosurgeon in two weeks. Please pray. Thank you, dear sisters.
Oh, Dear Kelly, I do often pray for you. I'm sad to hear that Dennis is not doing well. I will pray that the neurosurgeon is able to help. God be with you and may you feel our loving arms around you as well.
Certainly am praying for you and your husband. Your lives have been turned upside down. So many dreams for the future now being reconsidered, reevaluated. And men do not like to feel helpless, out of control, any more than we women do. I can't imagine the emotional struggle your husband is feeling as well as the physical issues. My heart breaks for both of you as you navigate this challenge. I'm praying for strength for you both. I'm praying for many to come alongside you to provide respite. And I'm praying that the doctors have answers for the latest decline in his recovery. I'm praying for even small daily joys to come your way to combat discouragement. Please continue to keep posting so that specific prayers can be offered on your behalf.
Pray that it will be clear on whether he needs a shunt or not. We visit the neurosurgeon in two weeks. Thank you, Churchmouse!
Praying for you, Kelly. Check out the book "Hope Heals" by Jay and Katherine Wolf. Written by a couple in similar circumstances who echoed your sentiments. I pray that reading their story encourages you in yours.
Thank you, Caroline! I am going to check into "Hope Heals" this evening.
Lifting you and your husband up in prayer.
I am so sorry to hear your husband isn't doing as well as he was. Praying for you both, that you will know and feel the love and comfort from our Savior and this community of sisters.
Oh, Kelly, I'm so sorry. Praying for complete restoration and for your heart in the waiting. Thank you for sharing these burdens with us.
Kelly, I'm stopping to pray for you and Dennis now!!
Praying for you dear sister! It is such a blessing to be part of the family of God that prays for one another. The world does not understand our connection. Miles, age, cultures….none of that separates. Jesus unites us.
Yes, so true and thank you!
Kelly, I am praying for you too. Ladies, we have developed a habit of Bible Study because this is our manna from Heaven!! God Himself has sent us a message and we do not want to live without it.
Praying, Kelly…your honest, gut-level sharing, also reminds me to pray for a friend whose husband has Parkinson's…I'll lift you together to the throne!!
I am adding my prayer to those of the others. May you feel comfort and assurance during this difficult time. May You feel strength from the Lord's arms wrapped tightly around you, and may you receive the wisdom you need to guide you on this journey.
https://www.desiringgod.org/articles/where-does-my-help-come-from. I found this when looking up Ps 121 to copy and paste here as it was the scripture that came to my mind as I prayed for you, Kelly. I pray it will encourage your heart as it did mine to remember God's faithful love.
May the Lord bless and keep you, your husband, and your kiddos.
I have the article loaded and I am about to read it. Thank you, Becky!
Thank you, Brittany! Excellent reminder to bring my prayers to God with thanksgiving and prayer, to not be anxious (working on it), and asking God for the wonderful, special peace that only He can bring! Thank you.
Praying for your husband and you through this time Kelly.
Kelly, my heart was so touched with the path on which you travel. I pray that God will give you a peace that passes all understanding. I often think when I get to heaven and can speak to The Father, I will ask him some of my why's. How dear and true is the song, "We'll Understand it All By and By".
I'm praying for you both, Kelly.
I have been thinking through this issue of late and so this devotional was very timely. My devotional times were feeling dry. I was going through the motions but didn't feel like I was getting much out of them. Then one day, I felt as though God asked me why I was doing them. Why do I sit down to my quiet time? I felt like during that time it had become out of ha it that I did it. Or even that I felt I had to so that God would be with me in my day. Originally, it had started out that I wanted to spend that quiet with God, to soak up those moments in quiet relationship with him, learning, growing, praising. It had become something that I did out of obligation or habit, an attempt to manipulate and in the process lost its meaning. I thank God for asking me that question that day so that I can get back to spending quality quiet time with Him. This is a great reminder and perhaps another little nudge to keep the lesson fresh in mind. So thankful.
Cathy, I love your honest comment. I too have my morning routine. Some may call it a habit. Without my time with Jesus and my coffee my day does not feel complete or orderly. I too have seasons of dry spells and I feel alone and lost. I often call on my strong prayer warriors when I cannot pray. Other seasons are dry and God is leading me through until I have the ahhhh moment. I too am thankful.
Yes, sometimes I feel as if I just sit down in the mornings more out of habit or to check my list of things to do. But my time with God is so much more! Nice to know I'm not the only one who struggles here.
I think rather than habit it is a Christian discipline. Keeping us in fellowship with our God, abiding with Christ, and being filled with the Holy Spirit which we are commanded to do by being transformed by the renewing of our minds through the Word of God. Romans 12. Part of being a living sacrifice – our spiritual act of worship.
I've also had the thought many times that I don't want it to be out of habit. But as I read comments it occurred to me that giving it the right term changes our whole perspective. Not a habit like brushing your teeth to be healthy physically but a 'Christian discipine' to keep me spiritually healthy.
Grateful for your fellowship here that spurs me on.
Cathy, I've felt, and still feel, the same way. My quiet time with God was lacking intimacy and had turned into something to check off my to-do list. I'm struggling because I do need accountability, but also crave the intimacy of real time with God. Praying for all of us struggling with this. I tried posting this through the app, but it said ID null, or something like that?
Micah chose a counterfeit god over the one true God. Idols are always less than and never enough. How foolish to feed the insatiable appetite of an idol. God promises an abundant life through a relationship with Him. It is a relationship not maintained through striving but through resting and abiding in Him. Religion is so often about doing when what God desires is indwelling. Relationship with Him satisfies in a way religion cannot.
Thinking of you and praying for you this morning.
God is much bigger than any religious box, idolatry, I might place him into. May I worship him in Spirit & in Truth.
Carol this is well stated!!
Very timely and much need words today! Thank you!

Dugout – the ultimate football platform for fans – launches first ever app
Dugout.com
Dugout, the world's first digital platform supported by the biggest football clubs and players, has today launched the company's first ever app – giving football fans unrivaled behind-the-scenes access and exclusive content straight to their mobile and tablet devices.
The app's release follows the successful launch of Dugout.com at the end of November 2016, which has already seen over 8 million users join the platform, 13 million page views and 37 clubs create their own pages – including nine of biggest clubs in the world.
This impressive list of partners includes A.C. Milan, Arsenal F.C., Chelsea F.C., FC Barcelona, FC Bayern Munich, Juventus, Liverpool FC, Manchester City FC, Paris Saint-Germain and Real Madrid CF, as well as over 100 of the world's best-known footballers.
Dugout President, Elliot Richardson, commented:
"Dugout was built for football fans across the world – delivering the ultimate place to explore and access the biggest clubs and players on the planet. The app launch is a huge moment for us because we now know most of our users are accessing the platform using their mobile, meaning that we can now give them a bigger, better and more personalised experience – with unparalleled amounts of exclusive and original content, produced by the world's biggest clubs and players working with Dugout and seen nowhere else, totally free."
Dugout President – Elliot Richardson
In addition to clubs and players, Dugout is partnering with leading football influencers and legends to create their own profile pages and produce content exclusive to Dugout users.
85% of Dugout's audience currently accesses the platform via their mobile devices, so the launch of the app is an important stage in the company's development. Available on both the App Store and Google Play, the app includes a wealth of new features including the ability for fans to create their own personalised experience by choosing clubs and players to follow; vertical video shot by players on their own phones; stunning image galleries; and new user interface functionality to make navigating and discovering content both simple and rewarding.
Also launching today is an exclusive iMessage Stickers pack for iPhone and iPad. This fun addition to the Dugout product suite means football fans will be able to send more than a dozen stickers in chat or layer them on top of photos in iMessage.
The clubs that already joined Dugout are: A.C. Milan, Arsenal F.C., AS Monaco FC, A.S. Roma, Atlético Madrid, Barcelona Sporting Club, Bologna FC 1909, C.D. Leganés, Chelsea F.C., Club América, Crystal Palace F.C., Everton F.C., FC Barcelona, FC Basel 1893, FC Bayern Munich, FC Porto, Galatasary S.K., GNK Dinamo Zagreb, Heart of Midlothian FC, F.C. Internazionale Milano, Juventus, Liverpool FC, Maccabi Haifa FC, Manchester City FC, Manchester City Women FC, Olympique De Marseille, Paris Saint-Germain, RCD Espanyol, Real Madrid CF, Santos FC, SC Corinthians Paulista, Southampton FC, Stoke City FC, Sunderland AFC, Swansea City AFC, Tottenham Hotspur, West Ham United.
Each club and player has a dedicated Dugout profile to upload content and interact with fans, and in addition Dugout works with these partners to create high-quality, original content. This content includes videos from clubs exclusive to Dugout before they're shared with the rest of the world, lifestyle and personal updates from players, and original video series featuring ball skills and tricks from players that can't be seen anywhere other than Dugout.
The trend of following multiple clubs – on average 4.6 clubs per person – was revealed in polling of 25 major football countries. The research also found that fans now "support" individual players, meaning that these stars help grow the global fan base of every team they play for during their career.
The Dugout app is initially available in eight languages: English, German, Italian, French, Spanish, Catalan, Portuguese and Bahasa (Indonesian), with more to be added in the coming months.

This short football language post talks about the phrase '(to/be) level', used as a verb or an adjective. If you have questions or comments, email us at: admin@languagecaster.com.
The word 'level' means 'even' or 'flat', and in football when used as a verb 'to level', it means that a goal is scored equalling the other team's score. The scores were levelled means, perhaps, that a team were losing one-nil but scored, bringing the scores to 1-1 – even, equal. So to level means to score and also bring the scores equal. It can also be used as an adjective – the scores are level, meaning equal. It is also used when talking about the rankings of teams in the league – team A and team B are level on points.

The hobby of radio-controlled or RC toys has increased to such an extent that both young and adults are getting into it. In the early 90s, kids only used some double A battery-driven cars with some flashlights and sound. Things have changed now. With RC toys, you can have both the toy and the radio equipment as well. Nowadays, RC toys come as cars, planes or even ship/boat. The shapes and designs have gone through some remarkable changes which don't actually look like toys. You will feel like you are actually using some real thing!
It's crucial that you possess some basic ideas before purchasing an RC toy. First of all, you don't want to end up destroying any part of it doing some amateur engineering work. Go through the manual first and set up properly. If you don't see it working, you have done something wrong. Keep going through the manual unless you find the problem. You can search YouTube with the RC toy model, and you will find something certainly. Secondly, if you are able to complete the setup properly, don't start operating immediately. Find a proper and secure place to learn how to handle it. You don't want to end up hitting your neighbour's window with your new drone! You may end up paying a lot.
RC toys can be both cheaper and expensive, based on the functional abilities. It is obvious that RC toys with better range, designs, and features will be more expensive. If you want to obtain the skill with RC toys, it's always better to start with cheaper one.
Nowadays, RC toys can be purchased from different online websites. However, you shouldn't simply pay the actual asking price without doing any online research. Take a look at our website to get some RC model toys and hobbies promotional codes to enjoy discount. You just need to select the product you want to purchase, and enter the discount code from the coupon at the designated spot. Once your discount code is successfully accepted, you will see the reduced price on the website. Who doesn't want to enjoy the discount? With this opportunity, you can get yourself inspired to shop more and more with discount codes. So, what are you waiting for? Start shopping and make your hobbies more interesting.

Village Square at Dana Park in Mesa Welcomes Rodizio Grill
Village Square at Dana Park in Mesa Welcomes Popular Brazilian Restaurant Rodizio Grill
First Location in Arizona for Nationally-Acclaimed Steakhouse
Whitestone REIT announces Rodizio Grill, America's First Brazilian Steakhouse, will soon open in Mesa's premiere lifestyle shopping center, Village Square at Dana Park on South Val Vista Drive and the U.S Highway 60. Its first location in Arizona; The Grill will introduce an authentic Brazilian dining experience with a spirit of fun, adventure and alegria (happiness).
"Rodizio Grill offers an experience that transports you to Brazil, with all its culture and tastes. Here you can escape the ordinary. And it's well suited for any occasion, whether it be a date night, business luncheon, or family celebration," says Nick Clayton, co-owner of the new Rodizio Grill – Mesa, and owner of Rodizio Grill in Milwaukee.
Rodizio Grill holds three annual promotions unique to Rodizio Grill: Bacon Fest, Rodizio Americano BBQ Fest, and Wild Game Fest. These events offer the traditional Rodizio favorites alongside limited-time custom menu items created to tempt, challenge and dazzle taste buds.
Opening in a 6,900-square-foot space north of California Pizza Kitchen, the restaurant features rotisserie grilled meat, expertly seasoned and carved tableside by traditionally dressed Gauchos. While the meats are the main attraction, they are complemented with an award-winning gourmet salad bar, marked by original salads, fresh seasonal fruits and vegetables and authentic hot side dishes.
Established in 1995 in Denver, Colorado, Rodizio Grill was the first Brazilian "churrasco" steakhouse in the United States and the Dana Park restaurant is the first location in Arizona.
"Over the past 20 years, the number one market request from guests has been from the Phoenix metropolitan area," says Ivan Utrera, Founder and President of Rodizio Grill. "From our humble beginnings in Denver, Colorado, through our expansion throughout the nation, we've always wanted to be able to come here. We're perfectly delighted to finally realize that dream."
Other changes to Dana Park include the opening of Relax the Back, a specialty store that sells back support products and self-care solutions for customers seeking relief from back and neck pain, and, just in time for the Halloween season, the opening of Spirit Halloween Store. Additionally, there's been a name change for the former Beauty Spot, now Flow Hair Society. The salon is an approved Aveda Salon Products distributor; a professional hair and skin care line using plant and flower-based products that are good for the environment.
Daniel Kovacevic, Whitestone REIT Regional Vice President, Southwest Region, said he is pleased to welcome Rodizio Grill, Relax the Back, Flow Hair Society and Spirit Halloween Store to the shopping center at Village Square at Dana Park.
"These exciting new establishments are fantastic additions to Dana Park as we work on perfecting the mix and determining the market needs for this high-profile shopping center," Kovacevic says. "The Village Square at Dana Park has enormous appeal to locals and East Valley visitors and we are delighted to continue to contribute to the City of Mesa's economic growth."

If you are like most Americans today, you are surrounded by fast food chain restaurants. You are barraged by ads for junk foods. You see other ads, for weight loss programs, that say you can eat whatever you want, not exercise — and still lose weight. It's easier to find a Snickers bar, a Big Mac, or a Coke, than it is to find an apple. And your kids eat at a school cafeteria whose idea of a vegetable is the ketchup on the burgers.
You go to your doctor for health tips. In the waiting room, you find a glossy 243-page magazine titled "Family Doctor: Your Essential Guide to Health and Wellbeing." Published by the American Academy of Family Physicians, and sent free to the offices of all 50,000 family doctors in the United States in 2004, it's full of glossy full-page color ads for McDonald's, Dr. Pepper, chocolate pudding and Oreo cookies.
You pick up an issue of National Geographic Kids, a magazine published by the National Geographic Society "for ages six and up," expecting to find wholesome reading for youngsters. The pages, however, are filled with ads for Twinkies, M&Ms, Frosted Flakes, Froot Loops, Hostess Cup Cakes, and Xtreme Jell-O Pudding Sticks.
This is what scientists and food activists at Yale University call a toxic food environment. It is the environment in which most of us live today.
The inescapable fact is that certain people are making an awful lot of money today selling foods that are unhealthy. They want you to keep eating the foods they sell, even though doing so makes you fat, depletes your vitality, and shortens and degrades your life. They want you docile, compliant, and ignorant. They do not want you informed, active, and passionately alive, and they are quite willing to spend billions of dollars annually to accomplish their goals.
You can acquiesce to all this, you can succumb to the junk food sellers, or you can find a healthier and more life-affirming relationship to your body and the food you eat. If you want to live with radiant health, lean and clear and alive in your body, you'll need an ally in today's environment.
Fortunately, you have in your hand just such an ally. T. Colin Campbell, PhD, is widely recognized as a brilliant scholar, a dedicated researcher, and a great humanitarian. Having had the pleasure and privilege to be his friend, I can attest to all of that, and I can also add something else. He is also a man of humility and human depth, a man whose love for others guides his every step.
Dr. Campbell's new book — The China Study: Startling Implications for Diet, Weight Loss and Long-Term Health — is a great ray of light in the darkness of our times, illuminating the landscape and the realities of diet and health so clearly, so fully, that you need never again fall prey to those who profit from keeping you misinformed, confused, and obediently eating the foods they sell.
One of the many things I appreciate about this book is that Dr. Campbell doesn't just give you his conclusions. He doesn't preach from on high, telling what you should and shouldn't eat, as if you were a child. Instead, like a good and trusted friend who happens to have learned, discovered and done more in his life than most of us could ever imagine, he gently, clearly and skillfully gives you the information and data you need to fully understand what's involved in diet and health today. He empowers you to make informed choices. Sure, he makes recommendations and suggestions, and terrific ones at that. But he always shows you how he has arrived at his conclusions. The data and the truth are what's important. His only agenda is to help you live as informed and healthy a life as possible.
I've read The China Study twice already, and each time I've learned an immense amount. This is a brave and wise book. The China Study is extraordinarily helpful, superbly written, and profoundly important. Dr. Campbell's work is revolutionary in its implications and spectacular in its clarity.
If you want to eat bacon and eggs for breakfast and then take cholesterol lowering medication, that's your right. But if you want to truly take charge of your health, read The China Study, and do it soon! If you heed the counsel of this outstanding guide, your body will thank you every day for the rest of your life.

The French city Agen has a population of over 33 000 people. The city is located in the department of Lot-et-Garonne in Aquitaine. Agen is the capital of the department of Lot-et-Garonne.
The city is best known for the fact that here lived the famous prophet Nostradamus. After receiving his doctorate, Nostradamus moved to live in the city Agen where he started his medical practice. He managed to find personal happiness and married an incredibly beautiful woman who bore him two children.
But the gift of prophecy of Nostradamus paid a high price - he lost both his family and his medical practice. In Agen, an epidemic of plague broke out and the doctor who managed to save hundreds of people from disease, failed to save his own family. Cured by Nostradamus Agen citizens have made him into a charlatan and that led to bringing the court of inquisition here.
This story has attracted many tourists to Agen, who want to walk around the city, where once lived the famous prophet, to feel the atmosphere of antiquity. Agen has many attractions, but also many entertainment venues. One of the most crowded places in the city is the famous Agen swimming pool. The pool has a spa treatment that is known to people around the world.
Another popular spot is the Theatre du Jour. In practice it is a merger of two smaller theaters, which are part of the same theatrical company. This is one of the most visited places in the city at night.
The program of theater companies is extremely dynamic and offers both musical and drama, comedy, and dance performances. Theatre Ducourneau is perhaps the most famous theater in the city. It was built of stone and is one of the most imposing buildings in Agen. For decades, this theater is the largest cultural attraction of the beautiful French city.
Theatres are the most remarkable in Agen, because they are very interesting and offer incredible performances, presented in a completely different and innovative way. Theatre La Tannerie is not just a place where people gather to watch plays. This is a huge exhibition space, where talents from different fields of art can show the audience what they can do.
The incredible scene of the theater is one of the most attractive places for lovers of art. Despite the wide space and plenty of people the theater can hold, it creates a feeling of comfort and an intimate atmosphere. During the different months are held various shows, including musical productions, concerts, dance shows and theater performances.
Here is located the Agen Museum of Fine Arts. This is one of the cultural centers of the city, where great works of art are collected. The museum keeps a large collection of valuable paintings, which were collected from all over Europe.
Among them there are both French, and works by famous artists from different European countries. Pictures that are in the museum are painted in the last five hundred years. Among the paintings there are paintings of Goya and Sisley. The museum has a large collection of archeological artifacts. Among them one can see many interesting exhibits that shed light on the history of the city Agen.

\section{Introduction}

Diamond is a wide-gap material attractive for various usages because of
its unique physical and chemical properties.
Its practical applications range from ultraviolet light-emitting diodes, radiation detectors, single-photon sources, to biosensors.
Along with the recent progress of crystal growth techniques, such as
the chemical-vapor-deposition (CVD) and high-pressure high-temperature (HPHT)
methods, high-purity single crystals of diamond are becoming commercially available \cite{review}. It has been known that the dominant substitutional impurities in synthetic diamond are nitrogen and boron due to the proximity of the atomic size to that of carbon. The nitrogen impurities in diamond affect not only the spin relaxation time of electrons localized at nitrogen-vacancy centers \cite{Teraji}, but also relaxation dynamics of free excitons \cite{Naka09}.

To quantify nitrogen or boron impurities in diamond at parts-per-million (ppm) levels,
one can utilize absorption \cite{Sumiya} and secondary-ion mass spectroscopy (SIMS). However,
methods for evaluating nitrogen at parts-per-billion (ppb) levels below the
SIMS detection limits are not common \cite{Teraji}.
On the other hand,
the quantification method for boron impurities by cathodoluminescence \cite{Kawarada}
has been recently extended with the detection limit below 0.05 ppb \cite{BarjonB,BarjonPSSA}.
Because of the long-term difficulty of doping control and the quantification problem,
capture cross sections of carriers or excitons at impurities in diamond have been missing parameters for 20 years \cite{THz, pico}.

In this study, we have performed electron-paramagnetic-resonance measurements to
determine concentrations of substitutional nitrogen down to sub-ppb levels.
Also, boron impurities with concentrations below 2 ppb were evaluated by careful photoluminescence analysis.
On the basis of the assessed impurity concentrations, we quantitatively discuss
momentum relaxation times of charge carriers, which determine the carrier mobility,
in addition to capture cross sections of charge carriers and excitons.
The extraction of the cross sections was enabled by our careful quantification of impurity concentrations.
The capture lifetimes were found to be limited by interactions with impurities in high-purity diamond.

Five samples with unknown impurity concentrations were used in the experiments,
along with two standard samples (see Table \ref{tab1} for nitrogen and Table \ref{tab2}
for boron quantification).
The first letter of the sample names (C or H) designates the growth method, i.e.,
CVD or HPHT.
The standard sample (H2) for nitrogen quantification was cross-evaluated by
infrared absorption and SIMS, and the concentration of charge-neutral substitutional nitrogen was [N$^0_s$] $= 23\pm2$ ppm ($=4.1\times 10^{18}$ cm$^{-3}$).
The other standard sample (C0) for boron quantification is an epitaxial layer
of $13$ $\mu$m-thickness grown on a type Ib diamond substrate.
The boron concentration in the epitaxial layer was characterized by electrical measurements and
SIMS along the depth \cite{Hall}. The boron concentration averaged over the layer thickness was
$[B]=$102 ppb $(=1.8\times 10^{16}$ cm$^{-3}$).
For the samples examined (C6-H5),
the highest possible concentrations quoted by the suppliers were 50 ppb for boron
and 100 ppb for nitrogen \cite{Horiuchi}.

A substitutional nitrogen in diamond forms a nitrogen P$_1$ center.
Two electronic levels arise by the Zeeman effect under an applied magnetic field. Each level is
further split into triplets by the nuclear spin interaction originating from $^{14}$N
atoms with natural abundance of 99.64 $\%$.
The concentration of unpaired electrons, or that of the P$_1$ centers
can be determined based on the microwave absorption associated with the transitions
between these electronic levels \cite{Wyk}.
The electron paramagnetic resonance (EPR) signal was measured with
X-band microwave at a frequency of 9.6 GHz
for samples mounted in a dielectric cavity (Bruker, MD-5-W1, TE011) at room temperature.
The measurement was done in
the continuous-wave regime by using the spectrometer (Bruker, ELEXSYS E580).
The nitrogen concentration was obtained by using the relation:
\begin{equation}
[N_s^0]\propto I/(WQ\sqrt{P}),
\end{equation}
where $I, W, Q,$ and $P$ stand for
the EPR signal intensity, weight of the sample, cavity quality factor, and microwave power,
respectively.
The EPR signal intensity was evaluated at the limit of weak microwave power
to avoid the saturation effect.
This was facilitated by analyzing the power dependence of the EPR signals,
and then by choosing appropriate microwave power from sample to sample for quantification
(see Table \ref{tab1}).
The absolute concentration was evaluated by using the signal intensity from the standard sample (H2).

The boron concentration [B] was determined based on the photoluminescence
intensity of boron-bound excitons relative to that of free excitons \cite{BarjonB}.
The excitation source was 213 nm wavelength light from a tunable laser based on
an optical-parametric-oscillator system (Ekspla, NT242).
The pulse duration was 2.5 ns and the repetition rate was 1 kHz.
Instead of the continuous excitation used in Ref. \cite{BarjonB}, pulsed excitation was used here but with a minimized laser power (e.g., 0.4 $\mu$W), so as to achieve suitable conditions for the quantification.
The measurements were performed at 7 K for samples mounted in a closed-cycle cryostat.
The photoluminescence signal was detected by a CCD camera (Andor, DU940N-BU2)
at the exit of a monochromator (Horiba Jobin Yvon, iHR-550, 2400 grooves/mm grating).
The entrance slit of the monochromator was set at 150 $\mu$m
to achieve sufficient signal intensities under weak excitation.
The absolute boron concentration was determined by comparing the
PL intensity ratio with that of the standard sample (C0) measured under identical conditions.

\section{Results and discussion}
\subsection{Impurity quantification}

\begin{figure}[tb]
\centering
\includegraphics[width=8.5cm,clip]{Figure1.eps}
\caption{EPR spectra of the (-1/2, 0) $\rightarrow$ (1/2, 0) transition
of the substitutional nitrogen (P$_1$) center in various samples.
Dashed lines are the best fit functions. Thin full lines are drawn to estimate the errors
($\epsilon=\pm 0.2$ for H7 and $\epsilon=\pm 0.3$ for C6).}
\label{fig:01}
\end{figure}

Figure \ref{fig:01} shows EPR spectra obtained from each sample.
Here, we focus on the (-1/2, 0) $\rightarrow$ (1/2, 0) transition,
where the numbers in parentheses indicate the electron spin and the nuclear spin.
The center magnetic field $B_0$ corresponds to $g=2.0027 \pm 0.0002$.
The spectral shape of the EPR signals is generally given by a Lorentzian function, but here it is represented in a differential form due to the magnetic field modulation (modulation width = 0.1 Gauss) to improve the sensitivity.
The EPR signal intensity $I$ in Eq. (1) is obtained by integrating a raw signal twice over the magnetic field strength.
Alternatively, $I=\pi ab$ is obtained by fitting the data with a differentiated spectral function,
\begin{equation}
L'(B)=-ab^2\frac{B-B_0}{[b^2+(B-B_0)^2]^2}.
\end{equation}
The dashed lines represent the best fit functions. The evaluated signal intensity $I$
and estimated nitrogen concentration [N$_s^0$] are summarized in Table \ref{tab1}.
The errors for a concentration below the ppb level were
carefully evaluated by comparing the data with the
 best fit function magnified by a factor of $(1+\epsilon)$, where $\epsilon$ yields
the relative uncertainty.
These spectral functions are shown by thin full lines in Fig. 1.
The minimum nitrogen concentration estimated was of the order of 0.1 ppb,
which corresponds to $1.76\times 10^{13}$ cm$^{-3}$.

Concerning the boron concentration, we referred to the previous publication \cite{BarjonB} on the ratio $R$
of cathodoluminescence from bound and free excitons
in boron-doped diamond. In order to reduce errors during the quantification procedure,
we mounted three samples in the same holder to compare.
The obtained photoluminescence intensity ratio and the boron concentration are summarized in Table \ref{tab2}.
The photoluminescence from bound excitons was below the detection limit in C1 and C6, thus we
provided in Table \ref{tab2} an upper bound for the boron concentration by considering the signal-to-noise ratio.

\subsection{Capture lifetimes}

\begin{figure}[t]
\centering
\includegraphics[width=7.5cm,clip]{Figure2.eps}
\caption{(a) Normalized intensity of the cyclotron resonance signal for electrons
at 10 K in various samples. (b) Plot of capture lifetime as a function of total impurity concentration.}
\label{fig:02}
\end{figure}

The above result indicates that the nitrogen concentration is higher than the boron concentration in most samples.
By using these assessed samples having different impurity concentrations, we discuss influence of impurities on the exciton or carrier capture lifetimes.
Figure \ref{fig:02}a shows normalized intensity of cyclotron resonance signals for electrons
at 10 K in various samples measured in our previous work with
photoexcitation at around 223 nm \cite{AkimotoDRM,NakaPSSA}.
The decay time was extracted as a 1/e time or by convolving an exponential
decay function with a Gaussian responsible for the excitation pulse and the system response function.
The decay time largely depended on samples.
Figure \ref{fig:02}b is a plot of measured decay time as a function of the total
impurity concentration.
That is, the horizontal axis of the figure is [$N_s^0$]+[B].
The symbols connected with lines are capture lifetimes calculated by
\begin{equation}
t=\frac{1}{v(\sigma_A n_A +\sigma_D n_D)},
\end{equation}
where, $v=\sqrt{3k_BT/m^*_{dos}}$ ($m^*_{dos}=0.496 m_0$ \cite{Naka13})
is the electron thermal velocity determined by the temperature $T$,
$\sigma_A, \sigma_D$ are the cross sections of electrons against capture to boron and nitrogen, and
$n_A, n_D$ are acceptor or donor concentrations. We take $n_A=[B]$ and $n_D=[N_s^0]$
by assuming neutralization of compensated impurities by photoexcited carriers as proposed in Refs. \cite{Fukai,Barjon2007}.

The cross section, $\sigma_D=1.4 \times 10^{-15}$ cm$^2$, for nitrogen at 10 K was taken
from terahertz time-domain spectroscopy \cite{THz} on electron capture at nitrogen.
The cross section for boron was estimated considering the difference of the
effective Bohr radius of impurity states, as given by $a_A=\hbar/\sqrt{2m_0 E_A}=5.5 \AA$
and $a_D=\hbar/\sqrt{2m_0 E_D}=2.6 \AA$,
where $E_{A(D)}= 0.37 (1.7) $ eV is the acceptor (donor) activation energy.
Here, a hydrogen model was assumed both for boron and nitrogen levels.
According to the model of classical collision between hard spheres,
the collision cross section is given by $\sigma_{A(D)}=4 \pi a_{A(D)}^2$.
This scaling relation yields $\sigma_A=\sigma_D a_A^2/a_D^2=6.3 \times 10^{-15}$ cm$^2$, and the calculated capture lifetimes are shown by open squares.
A better agreement with data was obtained with slightly larger cross sections
$\sigma_A=1.3 \times 10^{-14}$ cm$^2$ and
$\sigma_D=2.8 \times 10^{-15}$ cm$^2$ (circles).
The measured lifetime for C6 was shorter than the calculated ones
assuming the boron concentration at the upper bound. This implies
existence of other kind of structural defects or impurities,
such as hydrogen, silicon, interstitials, or dislocations, acting as a center capturing electrons in the CVD-grown diamond.
Further, because of the larger cross section for boron than for nitrogen,
the electron capture time more sensitively depends on the boron concentration.
This is why the plot does not look linear to the total impurity concentration.

\begin{figure}[t]
\centering
\includegraphics[width=7.5cm,clip]{Figure3.eps}
\caption{(a) Normalized PL intensity of free-exciton luminescence in C1, H7 and C6 at 7 K.
(b) Plot of capture time (lifetime) as a function of total impurity concentration.}
\label{fig:03}
\end{figure}

Figure \ref{fig:03}a shows normalized PL intensity of free-exciton luminescence following the 2.5 ns pulsed excitation in C1, H7 and C6 at 7 K. Detailed experimental setup for this measurement is
described elsewhere \cite{Morimoto}. After the fast decay due to many-body effects,
the 1/e time of the second decay component indicates the time for free excitons
to be captured by impurities. The capture lifetimes were obtained as 4.8, 28, and 430 ns
for C1, H7, and C6, respectively.
The analysis for decay times shorter than the duration of the laser pulse involves large errors because separating many-body effects is not straightforward. Nevertheless, there is a clear tendency that
the capture lifetime was shorter for a sample with a higher concentration of impurities.
Figure \ref{fig:03}b is a plot of the capture lifetime as a function of
total impurity concentration.
The calculations were performed based on Eq. (3),
where $v=\sqrt{3k_BT/m^*_{ex}}$ is the exciton thermal velocity
with the translational effective mass $m_{ex}^*=0.76 m_0$ \cite{Naka13}
 and $\sigma_A, \sigma_D$ should be replaced by the cross sections of excitons,
$\sigma_A^{ex}$ and $\sigma_D^{ex}$.
We assumed $\sigma_A^{ex}=3.1 \times 10^{-14}$ cm$^2$ after Ref. \cite{pico} for boron, where
a factor of $\sqrt{8/(3\pi)}$ was multiplied to correct the difference in definitions of
thermal velocity. The cross section for nitrogen is not exactly known,
because the direct measurement is difficult due to the fast Auger process.
For the calculation as shown by squares, the capture cross section
$\sigma_D^{ex}=4.7 \times 10^{-14}$ cm$^2$ for phosphorous \cite{pico}
is used in place of that for nitrogen.
A reasonable agreement with the data was obtained when we adjusted the
cross section for nitrogen as $\sigma_D^{ex}=3.1\times 10^{-14}$ cm$^2$, as shown by circles.

Here we would like to summarize the obtained cross sections
and compare the values for carriers and for excitons.
The electron cross section for boron
$\sigma_A=1.3 \times 10^{-14}$ cm$^2$ is larger than that for nitrogen
$\sigma_D=2.8 \times 10^{-15}$ cm$^2$,
and both are smaller than the exciton cross sections
$\sigma_D^{ex}=\sigma_A^{ex}=3.1 \times 10^{-14}$ cm$^2$.
This means that electrons have less chances to be captured by impurities than excitons.
The difference seems to come from the difference in the Bohr radius ($a_A$, $a_D$) of carriers
and that ($a_B^{ex}$) of excitons. Again, by assuming classical collision between hard spheres,
the Bohr radius scales proportionally to $\sqrt{\sigma}$.
Therefore, the excitonic Bohr radius is roughly estimated as $a_B^{ex}=a_A\sqrt{\sigma_A^{ex}/\sigma_A}$
 by using the acceptor cross sections, and $a_B^{ex}=a_D\sqrt{\sigma_D^{ex}/\sigma_D}$ by using the donor cross sections. Both relations coherently lead to an exciton Bohr radius of 8.6 $\AA$.
Considering the crudeness of the hydrogen model, this value is not far from
the value, $a_B^{ex}=13.7$ $\AA$, derived from the exciton binding energy of 92 meV\cite{Sauer}.
Therefore, exciton capture is determined by the exciton Bohr radius rather than
by the effective radius of impurities.

The good agreement obtained above between the experimental data and theory
implies that neglecting ionized impurities is reasonable.
Additionally, capture by impurity complexes such as nitrogen-vacancy centers should not be
significant because
the density of the centers are small, at least 1/200 times [N$_s^0$] \cite{Teraji2},
and the cross section is known to be very small ($10^{-15}$ cm$^2$) \cite{NVcapture}.
The excitons in diamond are bound by neutral impurities but unbound by charged impurities due to the relatively small mass imbalance between electrons and holes \cite{Dean}.

\subsection{Momentum relaxation time of charge carriers}

\begin{figure*}[bht]
\centering
\includegraphics[width=17cm,clip]{Figure4.eps}
\caption{Solid squares: scattering times measured at 10 K in different samples for

scattering. The dashed dotted lines in (a,b,c) represent
the sum of (ni) and (ii) scattering calculated with $0.1\%$ $N_i$.

sum of (ni), (ex) and (ii) scattering with 0.1$\%$ $N_i$.
}
\label{fig:04}
\end{figure*}

In this subsection, we compare the momentum relaxation time (or the scattering time in short)
of charge carriers in different samples.
The thermal average of the scattering time, $\tau$,
 is directly related to drift mobility by the relation $\mu=e\tau/m_c^*$,
where $e$ is the elementary charge and $m_c^*$ is the conductivity effective mass.
According to the Mathiessen's rule, the scattering time is approximated by
the inverse of the sum of the rates due to intrinsic and extrinsic scattering processes.
The intrinsic process is well known to be dominated by phonon scattering \cite{AkimotoAPL}.
If the extrinsic scattering processes are dominated by impurity interactions, one can, in principle, predict the drift mobility
of charge carriers in assessed samples, after precisely knowing impurity concentrations.

The measurements of the scattering time were done by means of cyclotron resonance \cite{NakaPSSA}, where the ratio of the resonance width to the resonance magnetic field yields the value of $\tau$.
With decreasing temperature $T$, the scattering time $\tau$ increased as $T^{-3/2}$
down to 50 K, in agreement with the acoustic-phonon scattering theory.
At lower temperatures, $\tau$ approached a constant value
with a weaker temperature dependence than $T^{-3/2}$.
The low-temperature scattering time was shorter for diamond containing
impurities of higher concentrations (see the plot of 1/$\tau$ in Fig. 12 of Ref. \cite{NakaPSSA}).

The scattering times at 10 K in assessed samples are plotted by solid squares in Figs. \ref{fig:04}(a)-(c), respectively for the electron, light, and heavy hole.
The longest scattering time was measured for the electron in C6 whereas
the shortest one was measured for the heavy hole in H6.
The resonance spectra in H5 were too broad to extract an accurate scattering time.
The right axis of each panel represents the mobility value obtained by using the conductivity effective masses, $m_e^*=0.385 m_0$, $m^*_{lh}=0.26m_0$, and $m^*_{hh}=0.66m_0$.

The most obvious contribution to charge carrier scattering comes from neutral impurities (ni), whose theoretical scattering time is given
by Erginsoy formula \cite{Erginsoy} for an electron-hydrogen scattering model
and its modification to a positron-hydrogen scattering picture by Otsuka, Murase, and Iseki \cite{Otsuka}. That is,
\begin{equation}
\tau_{ni-e}= m^*_{dos}/(3.4 n_A a_A \hbar+20 n_D a_D\hbar) \propto m_{dos}^*,
\end{equation}
for an electron, and
\begin{equation}
\tau_{ni-h}= m^*_{hh(lh)}/(20 n_A a_A\hbar+3.4 n_D a_D\hbar) \propto m_{hh(lh)}^*,
\end{equation}
for a hole.
As shown by circles in Figs. \ref{fig:04}(a)-(c),
the calculated scattering times for (ni) are quite longer than experimental data,  especially for the heavy hole. In the following paragraphs we discuss the other possible contributions.

A source for the short scattering times measured for the heavy hole could be fluctuation in isotopic composition of natural carbon (98.9 $\%$ $^{12}$C and 1.1 $\%$ $^{13}$C).
The isotope scattering is modeled by alloy scattering \cite{alloy} with the scattering time expressed as,
\begin{eqnarray}
\tau_{iso}=\frac{(2\pi\hbar^2)^2}{\pi m_{dos}^{*2}}
\left(\frac{dE_c}{dx}\right)^{-2} \frac{1}{a_0^3 x \sqrt{3k_BT/m_{dos}^*}} \propto m_{dos}^{*-3/2},
\end{eqnarray}
where $x=0.011$ is the fraction of $^{13}$C, $a_0=3.57 \AA$ is the lattice constant of diamond, and $dE_c/dx=14.6$ meV is the isotopic gap shift \cite{Kanda}.
The calculated scattering times are $\tau_{iso}=$ 1.5$\times10^{-7}$ s, 2.2$\times10^{-7}$ s, and 5.5$\times10^{-8}$ s for the electron, light hole, and heavy hole, respectively.
As these values are much larger than the experimental data, we conclude that their contributions to the mobility are not significant.

A local strain could also be a source for carrier scattering.
An order-of-magnitude scattering time is in the $10^{-10}$ s range according to Eq. (3) of Ref. \cite{disloc}:
\begin{equation}
\tau_{strain}=\frac{32}{3\pi}\left(\frac{1-\nu}{1-2\nu} \right)^2\frac{k_B\hbar}{\Xi^2
\lambda^2N}T,
\end{equation}
where $\nu=0.18$ is Poisson ratio, $\Xi=8.7 (10)$ eV is the deformation potential for
the electron (light and heavy holes) \cite{AkimotoAPL}, and $\lambda$ is
the unit crystallographic slip distance taken to be equal to the lattice constant.
Here we assumed dilations around edge-type dislocations at a density of $N=10^5$ cm$^{-2}$,
which is a typical value in samples with the same grade as C6 and orders of magnitude greater than that in HPHT samples (H7 is dislocation-free).
The theoretical scattering time is independent of the effective mass,
and does not explain the discrepancy between (ni) and squares in Fig. \ref{fig:04}.

On the other hand, the case of ionized impurities (ii) deserves to be considered since samples are compensated. Calculated scattering times for ionized impurity interaction according to the Conwell Weisskopf formula \cite{Ridley},
\begin{equation}
\tau_{ii}=\frac{64\sqrt{\pi m_{dos}^*}\epsilon^2(2k_BT)^{3/2}}{e^4 N_i\ln [(1+144\pi^2\epsilon^2k_B^2T^2/(e^4N_i^{2/3})]} \propto m_{dos}^{*1/2},
\end{equation}
are represented by triangles in Figs. 4(a)-(c) when using the density $N_i=2$ min([B], [N$_s^0$]) as listed in Table II
\footnote{Given a 10$^{4-5}$ cm$^{-2}$ dislocation density, it would provide
a negligible amount of charged centers compared to $N_i$.}
and the dielectric constant $\epsilon=5.7$.
With such inputs, the calculated (ii) scattering times are about two orders of magnitudes shorter than the measured ones.
This result indicates that the actual density of ionized impurities is much smaller than $N_i$.
The dashed dotted lines in Figs. 4(a)-(c) are instead calculated with the neutral impurities and a concentration of ionized impurities equal to 0.1$\%$ $N_i$. The relatively good agreement with experimental data indicates that at least 99.9$\%$ of the compensated impurities are neutralized by photoexcited carriers,
in consistency with the assumption made in Subsection B for the analysis of capture lifetimes.
Our result also broadens the context known by the first experiments in silicon \cite{Fukai},
where ionized impurity scattering plays a minor role in cyclotron resonance under photoexcitation
compared to Hall-effect measurements.

Finally, we had to consider scattering between free carriers and excitons \cite{Ohyama}
because the short scattering times for the heavy hole are still not correctly described
with both neutral and ionized impurities. The carrier-exciton collision
 occurs with a scattering time $\tau_{ex}=1/(Q n_{ex} v),$ where $Q$ is the
exciton-carrier cross section.
The cross section depends on the mass ratio of scattering particles
and thus on the carrier species. Our estimates based
on the literature \cite{Elkomoss} give rise to
$Q_e=2.6\pi (a_B^{ex})^2=1.4\times 10^{-13}$ cm$^2$,
$Q_{lh}=3\pi (a_B^{ex})^2=1.6\times 10^{-13}$ cm$^2$, and
$Q_{hh}=42\pi (a_B^{ex})^2=2.2\times 10^{-12}$ cm$^2$.
The exciton-carrier cross section for the heavy hole is found to be
one order of magnitude higher than that for the electron or light hole.
This can be understood by the fact that
the interaction potential for exchange of the incident carrier and that of
the exciton becomes repulsive when the mass ratio exceeds unity, which is the only case
for the heavy hole.
The calculated scattering time for the exciton density of $n_{ex}=
10^{15}$ cm$^{-3}$ is $2.4\times 10^{-9}$ s, $1.5\times 10^{-9}$ s, and $1.7\times 10^{-10}$ s
for the electron, light hole, and heavy hole, respectively at $T=10$ K.
The particular behavior of heavy-hole scattering times as measured by cyclotron resonance is probably a signature of a significant exciton-carrier scattering. At the end,
the dashed lines in Figs. 4(d)-(f) correspond to
the sum of (ni) and exciton scattering. By adding the
contributions of 0.1$\%$ $N_i$ ionized impurity scattering, as shown by the full lines,
a reasonable agreement with the data (solid squares) is obtained.

Although we have not reached a perfect agreement, our first attempt to preliminary determine
the mobility seems to be successful to reproduce the general tendency.
It is unique to diamond that both charge carriers and excitons coexist up to room temperatures and above.
Since such a situation is realized only at cryogenic temperatures in prototypical semiconductors like Si and GaAs, further investigation of diamond at higher temperatures would be interesting. On the other hand,
studies toward the other extreme, i.e., higher purity diamond at ultralow temperatures
in the absence of neutral impurity scattering would also be fascinating.
When a higher sensitivity for detection is achieved and carrier-exciton scattering is suppressed, carrier mobility limited by isotope scattering might be seen for the first time in semiconductors.

\section{Conclusion}
We have quantified substitutional nitrogen and boron concentrations in
several synthetic diamond crystals down to sub ppb levels.
The capture lifetimes of electrons and excitons as well as the carrier scattering times
were discussed as a function of impurity concentrations.
We extracted the cross section of electrons by boron impurity, and that of excitons
by nitrogen impurity, which had been unknown so far for diamond.
The scattering times of charge carriers with impurities, carbon isotopes, and excitons were quantitatively
calculated, and the comparison with measured data
indicated an almost complete neutralization of compensated impurities by photoexcited carriers.

The present study opens a new avenue to access the detailed understanding of dynamics
of the coexistent system of charge carriers and excitons.
The information obtained in the present study should be useful for predicting mobility-lifetime ($\mu\tau$) products in intrinsic layers of diamond diodes
as well as charge carrier collection efficiencies in diamond detectors.
