The Canadian PressALEXIS CREEK, B.C. – The chief of the Tl’etinqox First Nation said RCMP officers told them to leave or risk having their children taken away. Instead, they erected a fire boundary and prepared to fight.“We are generation after generation that continue to live in a fire zone. This is not new to us,” said Chief Joe Alphonse, whose community is about 100 kilometres west of Williams Lake. “We feel this is the safest place for our community members to be.”Emergency officials and police are urging British Columbia residents to respect evacuation orders ahead of fast-moving wildfires, but some First Nations are standing their ground, successfully protecting their homes and property.There are about 1,000 residents on the reserve, but Alphonse said only about 300 stayed to fight the fires.BC Wildfire Service chief information officer Kevin Skrepnek said there had been a slight reprieve in the weather forecast with some rain expected, bringing relief to the windy, hot and dry conditions fuelling nearly 200 fires and displacing more than 14,000 people.Crews took advantage of calmer conditions Wednesday to make progress on fire guards near Williams Lake, where 10,000 people remain on evacuation alert.With improved conditions, Alphonse said he finally had a moment to reflect on the three days of firefighting without the aid of power or telephone service.He said Mounties told them to evacuate last weekend and the conversation quickly became heated.As chief, he said his signature is required to enforce the evacuation order on the reserve, which he chose not to authorize.Robert Turner of Emergency Management BC said Alphonse was correct. First Nations have the authority to issue their own evacuation orders for their territory.“They would hopefully be taking advice from the same experts as a local government,” he said.Alphonse said many in the community wanted to stay behind to fight and they have trained firefighters, access to heavy equipment and emergency plans to evacuate if they lost the battle with the fire.He said an officer threatened to have the Ministry of Children and Family Services “remove all the children.”Tempers flared and Alphonse said he suggested their own roadblocks would keep the Mounties out and if that didn’t work, perhaps warning shots above their heads would.RCMP Staff Sgt. Annie Linteau said in a statement Wednesday, “as far as the comments made by Chief Alphonse, we do not believe the comments made are reflective of the recent and continued meetings and conversations we have had with the chief.”The RCMP’s responsibility is to “advise the public that there has been an order and advise them of the risk associated with staying,” Linteau told reporters on a conference call.“Of course, if the person has the ability to make their own decision and they are over the age of 19, we will not force them to leave the home,” she said.But she said if there are children under 19 at risk, police are required to move them to a safe location. No children have been removed by the RCMP to date, she added.Alphonse disagrees that officers were trying to protect their children.“The safest place for our kids is here with their families under the supervision of the leadership of this community,” he said.The Union of B.C. Indian Chiefs said Indigenous Peoples have a fundamental right to make decisions about protecting and defending the safety, health and well-being of their community.“If and when houses and band infrastructure are lost to these fires, it will take years to rebuild and we fear in many instances the homes and infrastructure may never be built,” said Grand Chief Stewart Phillip.Indigenous and Northern Affairs Canada said in a statement that the department is working with Emergency Management BC and First Nations to make sure the communities are supported.B.C. Forest Minister John Rustad told radio station CHNL that the province was concerned about the situation.“People are staying behind, they want to fight for their homes. That poses a very serious problem. We know these fires can be very, very volatile and can change at a moments notice,” Rustad said.Ultimately, Alphonse said staying was the right decision and it saved at least 10 homes.The chief of the Bonaparte Indian Band north of Ashcroft said they also defied an evacuation order over the weekend and successfully stopped flames from overrunning their reserve.“My community has some really skilled firefighters, like a lot of First Nations reserves, and they came together and they stopped that wildfire from wiping out that whole community,” Chief Ryan Day said.He said 60 of the band’s 280 members stayed to fight the fire.The community doesn’t have a firehall, a new water reservoir hasn’t been connected to their main supply yet and they don’t have a formal emergency response plan in place.But Day said the experience of the trained forest firefighters in his community and access to heavy equipment contributed to their success.“We weren’t prepared for it of course because it happened in a blink of an eye, but we snapped into action and everyone did their part,” he firstname.lastname@example.org
Anyone with information is asked to contact the Tumbler Ridge RCMP at 250 242-5252.TUMBLER RIDGE, B.C. – Search and Rescue crews are continuing the search for a man who went missing near Kinuseo Falls on Saturday night.The Tumbler Ridge Search and Rescue is being supported by the North Peace Search and Rescue and the South Peace Search and Rescue in their search for the man, who was camping on an island at the bottom of the falls in Monkman Provincial Park when they were last seen.Search and Rescue crews are asking boaters to stay off the Murray River unless they have signed up with Search and Rescue crews to assist with the search. A post on Facebook by the Tumbler Ridge Search and Rescue organization says a swift water response team is in place.According to a post on Facebook, the missing person, who can be seen standing below the falls in a photograph while fishing, was wearing the same clothing when they disappeared. UPDATE: North District RCMP spokesperson Cpl. Madonna Saunderson said in a release that the search is continuing today with multiple trained personnel on site, including four jet boats that are searching the Murray River, the RCMP helicopter and Police Dog Services.A 29-year-old man from Dawson Creek was camping with friends near Kinuseo Falls when it is believed he may have gone into the river. The RCMP were notified about the missing camper at around 6:30 on Sunday morning.Search and Rescue was immediately called to the scene, including a swift water trained team. Personal belongings believed to be the missing Dawson man’s have been found, however, the man has not been located. Posts on social media suggest the person standing is the one missing.Anyone wishing to help can check in at the incident command post which is located at the nine-kilometre marker of the Murray Forest Service Road, or by calling Sarah at (250) 242-7733. The RCMP are expected to provide more information about the search for the missing person later this morning.

New York (UN)-Moroccan foreign minister Salaheddine Mezouar underlined, in a letter Tuesday to UNSG Ban Ki-moon that Morocco has honored all its commitments and taken measures beyond those recommended by the UNSC, urging other parties to show a similar qualitative commitment. In the letter, also handed out to the 15 UNSC member states and to be issued as an official document by the executive body, Mezouar said that since the adoption of resolution 2099 last April, Morocco has honored all its commitments and taken measures beyond those recommended by the said body mainly regarding human rights.The minister stressed in the letter, few weeks away from the renewal by the UNSC of the MINURSO mandate, that the report by the UNSG which will be submitted in the weeks to come to the UNSC should take account, in its content, tone and recommendations, of the measures taken by the Kingdom. Morocco’s efforts seeking to reinforce the promotion and protection of human rights in all the national territory stem from an approach that is intentional by HM the King, the minister recalled, enumerating actions undertaken over the past years, namely the report by the economic, social and environmental council on the new development model for the southern provinces which is on the way to becoming operational, pursuant to the parameters of local good governance as laid down in the autonomy initiative.He added that, out of keenness to foster the role and efficiency of the national council for human rights (CNDH), the government announced last March its decision to react to all complaints by the CNDH, mainly from its two committees in Laayoune and Dakhla within three months.Regarding the interaction with special procedures, Morocco was visited since last April by the Special Rapporteur on trafficking in persons and the working group on arbitrary detention. Morocco has also announced that it is ready to welcome a new visit by the UN Special Rapporteur for torture to examine measures taken in this field.With MAP
Also, approval was granted to introduce amendments to the Sri Lanka Electricity Act enabling regulatory intervention on EVCS, enabling PUCSL to enforce user tariffs, licensing as well as imposing of safety and technical standards. Registration of electric motor cars in Sri Lanka has increased from 90 in the year 2014 to 3,238 in the year 2015. The Public Utilities Commission of Sri Lanka (PUCSL), the electricity sector regulator, today opened the path for public to comment on issues pertaining to an electric vehicle charging stations (EVCS) and its users in order to identify and draft the required regulatory tools.The Government empowered PUCSL to establish a register of EVCS at each distribution licensee- CEB and LECO, issue code of practice for EVCS, determine end user tariffs, issue safety and other technical standards for EVCS and collect information on a regular basis for monitoring purposes. Further, PUCSL plans to hold an oral submission on the same.The venue and the date of the meeting will be communicated to the interested parties at an early date. (Colombo Gazette) Total registration of electric motor cars from the year 2011-2016 is approximately 4,349 in Sri Lanka. Apart to a large number of electric motor cars, Sri Lanka also has a limited number of electric motor tricycles, motorcycles, dual purpose vehicles and single cabs.Around 50 privately owned Electric Vehicle Charging Stations (EVCS) are operating in the country, covering all main towns, catering to the growing number of customers using electric vehicles but remain unregulated due to lack of proper legislation. PUCSL invites stakeholders views, suggestions, recommendation, concerns and comments related to following areas;a) Requirement of maintaining and updating a register of authorized EVCS at CEB and LECOb) Code of practices for EVCSc) Determination of end user tariffs, safety and other technical standards for EVCSd) Rights and Obligations Statement for consumers of EVCSe) Issues faced by EVCS and consumers of such centresf) Issues related to residential charging facilitiesPUCSL wishes to introduce a regulatory mechanism to safeguard the rights of EVCS, consumers of such places in terms of economic, technical and safety aspects.The draft consultation paper is now available at www.pucsl.gov.lk for reference. A printed copy of this report also is available at the Information Centre of the Commission. Those who are interested can submit their written comments/submissions to the Commission by post/fax or e-mail and online via www.pucsl.gov.lk on or before 04th of October 2017.
Genesis is a new but growing luxury automotive brand that’s been winning over consumers with great value and high quality. Leading the charge is the 2019 Genesis G70, the brand’s all-new small sedan that it hopes will appeal to shoppers looking for sporty and invigorating performance. Notably, this exact demographic has long been claimed by BMW and its 3 Series sedan.BMW has completely redesigned its 3 Series for 2019, giving it fresh styling, more power and new technology features. Edmunds compares the upstart G70 to the benchmark 3 Series to find out which one is the better small luxury sport sedan.PERFORMANCE AND HANDLINGBMW has a long-running advertising tagline of “The Ultimate Driving Machine.” And Genesis must have been paying attention, as it recently hired some top ex-BMW employees to help design its cars. The results show. The G70 has two available engines: a 252-horsepower four-cylinder or a 365-horsepower V6. The V6, in particular, delivers the kind of effortless thrust we expect from this kind of car. The G70 is also impressively lively and engaging to drive around turns.The latest 3 Series has plenty of the brand’s trademark dynamic lustre. BMW offers two engines that feel stronger than the G70’s: a 255-horsepower four-cylinder engine and a 382-horsepower six-cylinder. The 3 Series also has excellent steering and very controlled handling.Overall, these two sedans are pretty evenly matched for being fun to drive. Yet it says a lot that the G70 can go toe-to-toe with the newest 3 Series.LUXURY AND UTILITYMost drivers will be impressed with the G70’s cabin. The available quilted leather upholstery, for instance, looks exceptional. But much of the switchgear comes from Genesis’ parent company, Hyundai. While the buttons and switches are easy to read and use, the feel of them isn’t quite up to the standard of the best European sedans.The new 3 Series is a high watermark for the nameplate. The interior trim is excellent, and there’s a luxury heft to all of the controls. The design is more subdued than what you’ll find in other luxury cars, but it’s unmistakably premium. On the downside, the controls aren’t as easy or intuitive to use as the G70’s.Both cars provide comfortable seating for front-seat passengers. The 3 Series has a definite advantage in back, however, as it offers more headroom and legroom for rear passengers. It also boasts significantly more trunk space.FEATURES AND TECHNOLOGYBMW has thrown its entire bag of tricks at the new 3 Series. For instance, a redesigned infotainment system features a new voice assistant that allows you to adjust many of the car’s controls just by speaking naturally. Unfortunately, the learning curve for operating the infotainment system is steep as many of the on-screen menus are convoluted.The Genesis doesn’t offer the same high-end vibe. Its infotainment system is similar to what you’ll find in a Hyundai, for instance, and it doesn’t have as many trick features or flashy graphics. But it’s easier to use than the BMW’s and comes standard with Apple CarPlay and Android Auto smartphone integration. In contrast, BMW doesn’t offer Android Auto, and Apple CarPlay is an option that requires annual subscription payments to keep working.Both cars received the Insurance Institute for Highway Safety’s highest Top Safety Pick Plus rating and offer many active safety features and driver aids. Just about all of them come standard on the G70. BMW, for its part, reserves some of these safety features as options. But it also offers a few extras you can’t get on the G70, such as a lane centring system that can make cruising on the highway easier for the driver.PRICE AND VALUEGenesis is aiming to increase the G70’s appeal by undercutting luxury competitors on price. A four-cylinder G70 2.0T starts at $35,895, while the four-cylinder BMW 330i starts at $41,245 (both prices include destination fees). This spread continues all the way up the line: Load up a range-topping, all-wheel-drive six-cylinder M340i, and you’re looking at more than $65,000. The price of a maxed-out all-wheel-drive G70 3.3T will be less than $55,000.You also get added peace of mind from Genesis’ warranty. The G70 has a five-year/60,000-mile basic warranty and a 10-year/100,000-mile powertrain warranty. BMW offers four years and 50,000 miles of coverage.EDMUNDS SAYS:Overall, we give the slight nod to the upstart G70. The new 3 Series is impressively polished and advanced. And although the G70 can’t quite match the 3 Series on refinement, it wins out by offering more fun and value for the money.___This story was provided to The Associated Press by the automotive website Edmunds .Will Kaufman is a content strategist and news editor at Edmunds.___Genesis G70 Review: https://www.edmunds.com/genesis/g70/BMW 3 Series Review: https://www.edmunds.com/bmw/3-series/Will Kaufman, The Associated Press
This week on Conversations with Goodman, host Susan LeBlanc talks with business student Sean Bouwers.Bouwers, set to graduate this summer, talks about his experience at Brock’s Goodman School of Business and how that has helped to set him up for a job upon graduating.Bouwers actively participated in several business competitions throughout his time at Goodman and placed third at Queen’s University’s Inter-Collegiate Business Competition (I.C.B.C.) and fourth in debate at JDC Central this year.He also took on leadership positions this past year with the Goodman Business Students’ Association as vice president finance and academic chair for the Goodman JDCC team.As he reflects on the past four years, Bouwers explains that a pivotal moment in his program was when he participated in an international exchange at Maastricht University in The Netherlands. After making several international connections through this experience, he took it upon himself to learn Mandarin and study Chinese culture.This led him to take part in a full immersion program in China last summer which was covered through a documentary-style show on CCTV’s Foreigners in China program.As Bouwers now looks forward to convocation, he is also looking forward to returning to China after he crosses the stage where a job in finance awaits him. He credits his strong co-curricular involvement in the business program as the pathway that led him to this job offer where he will be working in finance.As this partially stemmed from his international exchange experience, Bouwers encourages all students to participate in similar programs that broaden their horizons and open them up to a world of possibilities.This podcast is the latest in the Conversations with Goodman series which is produced by the Goodman Marketing, Communications and Alumni Relations team and features guests from the Goodman community.</p><div class=”flexvideo”></div><p> </p><p>
The Lance Corporal attached to the City Constabulary who was accused to engaging in sexual activities with a minor was on Monday remanded to prison when he appeared at the Georgetown Magistrates’ Court.Clifton Pellew was not required to plead to the charge which stated that the act was committed on August 15, 2017, while the 15-year-old victim was in his custody.The accused was remanded to prison and is expected to return to court on February 14, 2018.This publication had reported that at some point during his detention for reasons unknown, the minor was transferred to the Regent Street Outpost where the alleged incident occurred.Officer Quacy Baveghems had reportedly informed his superior of the act, claiming that he had witnessed it. However, as an investigation began into the matter, it was discovered that Baveghems did not make a written entry of the incident in the station diary.Pellew and Baveghems were fired, after receiving a letter signed by the Town Clerk.Georgetown Mayor, Patricia Chase-Greene had said that the decision to dismiss the officers came following the discovery of new evidence.“There were some additional information that was brought to the council’s attention and some video tapings. Based on those video tapes, and even though it was still an alleged allegation, in the best interest of the Constabulary and the Organization the Town Clerk as administrator of the city of Georgetown would have dismissed them both,” Chase-Greene added.The matter was subsequently transferred to the Police who sought legal advice from the Director of Public Prosecutions (DPP).This publication was told that after reviewing the file, the DPP has advised that Pellew be charged with the rape of a child under the age of 16 years.

The Voice over Internet Protocol (VoIP) telephone handset for underground two-way communications, has received MSHA approval for use in US coal mines. This is the latest component of MST’s tracking and communication system to be approved and completes the system’s ability to meet the conditions of the MINER Act 2006. The MinePhone is also relevant to hard rock mine operators, as MinePhones are already deployed in metalliferous mines. The MinePhone uses the MSHA approved ImPact Wi-Fi network or the standard non-IS ImPact network as the communication backbone to provide two way voice and texting along the primary and secondary escapeways underground. The MinePhone telephone handset allows private dialling between other phones in the network and the mine’s outside telephone system, as well as text messaging. Additionally, the MinePhone has 24 channels, Push to Talk functionality and emergency calling, emulating the functionally of many radios currently in use, but with many other functions available.The Wireless Network Switches (WNS’s) are the key part of the underground digital backbone and also act as readers for the Wi-Fi RFID Tags that are carried by miners underground, allowing a single communication network to provide both underground communication and tracking throughout the mine. “MST’s MinePhone is a breakthrough in underground voice and messaging communications, offering functionality never before available in coal mines” said Lloyd Zenari, CEO of MST. “The safety and productivity benefits for mining operations have quickly become apparent in metal mines and we expect the acceptance to be quicker still in coal operations”.
Newcastle’s boss Rafa Benitez has written off claims they are missing the services of Aleksandr Mitrovic who moved to Fulham in the summer transfer window.The sale of Mitrovic for £22.5m in the summer angered some sections of the fans but Benitez is adamant, insisting he would not have scored as many goals if he had remained at Newcastle.Asked if he had any regrets about effectively forcing Mitrovic out of the club, Benitez replied: “He is doing well, he did well for Serbia, but Rondon was doing well for Venezuela.Report: Courtois’s agent arrested in money laundering case George Patchias – September 11, 2019 Real Madrid’s Thibaut Courtois agent has been arrested as part of a money-laundering investigation.The ugly word corruption is again staining the world of football.

(Phys.org)—A combined team of researchers from Germany and the U.S. has taken a closer look at a type of bacteria that is able to cause ice to form, sometimes even under conditions above the normal freezing point. Explore further In their paper published in the journal Science Advances, the team describes the technique they used that allowed them to watch very closely what occurs as the bacteria promote ice formation and their discovery of the means by which the bacteria cause it to come about.Scientists have known for some time that some bacteria can promote the growth of ice crystals (they have been used to help create snow for ski resorts, as one example), but until now, the exact mechanism has not been closely studied. In this new effort, the researchers used a device called a sum frequency generation spectrometer to get a better look—it allows for a very close up view of a process as it takes place. In this instance, they watched as samples of Pseudomonas syringae went to work on both airborne water droplets and those that were on a surface. In so doing, they discovered that the bacteria use two different techniques to promote ice formation.The first technique involved a layer of proteins that surrounded the body of the bacteria—some were hydrophobic and others were hydrophilic—the opposing forces allowed the bacteria to shuttle water molecules around like a tiny tugboat, coaxing them into formations that were conductive to crystal growth.The second technique involved using vibrational energy to actually remove heat from the area surrounding the molecules that they had lined up, leaving them colder, which resulted in ice crystal formation at temperatures that were above freezing.The researchers note that the bacteria also have antifreeze proteins in their bodies to keep themselves from freezing. They add that their findings may have implications for Earth scientists, as ice causing bacteria play a major role in the creation of ice crystals in the atmosphere, and in frost formation on plants. More research into the process could also lead to the development of icing, or even de-icing products. Journal information: Science Advances Ice crystals: Max Planck researchers discovered that certain bacteria can affect the ordering and the dynamics of water molecules in water droplets. Thus, ice crystals develop already at zero degrees Celsius or just below, and not at minus 37 degrees Celsius as in pure water. Protein molecules at the surface of the bacteria are responsible for this process. Credit: R. Eckl © 2016 Phys.org More information: R. Pandey et al. Ice-nucleating bacteria control the order and dynamics of interfacial water, Science Advances (2016). DOI: 10.1126/sciadv.1501630AbstractIce-nucleating organisms play important roles in the environment. With their ability to induce ice formation at temperatures just below the ice melting point, bacteria such as Pseudomonas syringae attack plants through frost damage using specialized ice-nucleating proteins. Besides the impact on agriculture and microbial ecology, airborne P. syringae can affect atmospheric glaciation processes, with consequences for cloud evolution, precipitation, and climate. Biogenic ice nucleation is also relevant for artificial snow production and for biomimetic materials for controlled interfacial freezing. We use interface-specific sum frequency generation (SFG) spectroscopy to show that hydrogen bonding at the water-bacteria contact imposes structural ordering on the adjacent water network. Experimental SFG data and molecular dynamics simulations demonstrate that ice-active sites within P. syringae feature unique hydrophilic-hydrophobic patterns to enhance ice nucleation. The freezing transition is further facilitated by the highly effective removal of latent heat from the nucleation site, as apparent from time-resolved SFG spectroscopy.Read press release Chipping away at the secrets of ice formation This document is subject to copyright.
