Akierra Missick, who is also Minister for Education, Youth, Sport and Culture visited all three public schools on Providenciales in order to bring in the new academic year, welcome two new school principals, and to see for herself the progress made in the summer repair and refurbishment programmes in each property. She visited Clement Howell High School, Ianthe Pratt and Enid Capron Primaries, with the public schools on the other inhabited islands being visited throughout September.“It is great to see the staff and students returning to their classrooms after the one week delay caused by Tropical Storm Cristobal,” said Minister Akierra Missick. “The country is really bouncing back from the flooding, and the way that the parents and private companies around our public schools have joined in the effort to get things ready for the new term is very inspiring. “It is great to see new people with new ideas, in the form of our two new principals at Enid Capron and Clement Howell schools. I would like to congratulate them and send them our best wishes as they rise to their new challenges of professionally managing their establishments, and ensuring that their students are properly prepared for adult life, both academically, but also by becoming great citizens.”“I am very proud of my team over these past few weeks,” said Deputy Secretary Russell Cox. “They rose to the challenge of recovering from the storm and have also delivered a substantial work programme in our schools. I am sure that students, parents and teachers will welcome the repair and maintenance works conducted and will play their part in looking after our schools estate.” The Ministers were joined on their facility tour by Education, Youth Sport and Culture’s Permanent Secretary Cheryl Ann Jones and Director of Education Edgar Howell.ENDS Ministry of Education introduces pilot program Recommended for you Education Minister touts new ICT platform for Public Schools Education Minister tours schools this week

Rescue workers work at the wreckage of a US-Bangla airplane after it crashed at the Tribhuvan International Airport in Kathmandu. Photo: ReutersFour of the injured passengers of crashed US-Bangla Airlines plane are being brought back home from Kathmandu soon, reports UNB.Shahreen Ahmed is expected to be the first who is scheduled to land in Dhaka on Thursday afternoon.”I’m going back to Dhaka for continuing my treatment. There is no point to get stuck here on foreign land,” Shahreen told reporters from the hospital bed in Kathmandu just before her departure.She said her brother will accompany her in the Biman flight which is scheduled to land in Dhaka at 3:15pm.Responding to a question, Shahreen who sustained burn injuries said, “Almighty Allah saved me. Rescuers pulled me out from the aircraft.”Besides, two other injured — Eakub Ali and Emrana Kabir Hashi — will be taken to India soon, according to external publicity wing of foreign affairs ministry on Thursday.Severely injured Mehedi Hasan, Saiyada Kamrunnahar Shwarna and Almun Nahar Annie, will be brought to Bangladesh by their relatives.In this regard, no objection certificates (NOCs) have already been issued for them, it added.Moreover, three severely burnt injured were taking treatment at Kathmandu Medical College.Earlier on Wednesday, Rezwanul Haque, a severely burnt passenger of crashed US-Bangla Airlines flight, was sent to Singapore for better treatment.At least 51 people, including 26 Bangladeshi nationals, were killed as the US-Bangla Airlines aircraft crashed and burst into flames at Tribhuvan International Airport in the capital of Himalayan county Nepal on Monday.
(Phys.org)—One of the mysteries in biology is how cells can selectively diffuse potassium across a membrane. Biological systems rely on a delicate balance between these potassium and sodium ion concentrations in the surrounding environment and within the cell. Researchers, such as Dr. Bing Gong and his research group in SUNY Buffalo, have tried to solve this riddle by making synthetic ion channels that are selective for potassium. Journal information: Proceedings of the National Academy of Sciences The second area they investigated was the dynamic properties of the ion channels. In particular, Li, et al. looked at the lifetime of the ion-water bonds to determine the stability of the first hydration shell. They found that in bulk water and in all sizes of CNTs, the average lifetime of the Na+-water bonds were longer, and therefore more stable, than the K+-water bonds. Additionally, they found that confining any of the hydrated ions to a subnanometer-sized channel served to stabilize the bonds compared to bulk water. Diffusion studies also showed that confinement to a CNT increased the diffusion rate compared to bulk water. Notably, diffusion through SONP was hindered compared to the CNTs because of its rugged interior surface.The third area of investigation was in energetics. This is the key area that drives ionic selection. In general, because the sodium ion’s first hydration shell is particularly robust compared to the potassium ion’ shell, it would require more work to move the sodium ion from bulk water to the ion channel. Therefore, nanochannels with radii between 3.0 and 4.0 Å will selectively favor potassium. Of the particular systems tested, (8, 8) CNT with a radius of 3.7 Å, had the highest selectivity value for potassium ions.This research helps solve some of the mystery behind potassium ion selectivity in biological systems. It also provides evidence that (8, 8) CNTs are the best synthetic nanochannels for investigating potassium ion selectivity. Play AIMD simulation of confined water and a K+ ion in CNT (8, 8). Credit: (c) PNAS, doi: 10.1073/pnas.1513718112 To investigate this, they used two systems: a synthetic organic nanopore, which is comprised of macrocycles that form a rigid hydrophobic pore, and various single-walled carbon nanotubes. Macrocycles are large ring structures whose donor atoms will coordinate to ions. Often macrocycles are selective for particular ions. However, because of the dangling donor atoms, the interior of the channel is molecularly rugged. This may affect the flow of water through the channel. They used carbon nanotubes were as a comparison because they can vary the opening size of the nanotube and the interior of the nanotube is relatively smooth and hydrophobic, matching certain properties of biological ion channels.Li, et al. investigated three broad areas using ab initio molecular dynamics studies. They first investigated the hydration shell. Sodium and potassium ions attract the oxygen atom in water molecules. The water molecules surround the ions forming a “hydration shell.” The radius of the hydration shell, the number of waters molecules coordinated to the ion, and the orientation of the water molecules around the ion all provide molecular level information that may give clues as to how the ion channels can distinguish between two similar ions. Their studies showed that the sodium ion hydration shell is more structured and robust than the potassium hydration shell.

However, the physical mechanism underlying the K+/Na+ selectivity for the SONPs is dramatically different from that of natural ion channels. To achieve a better understanding of the selective ion transport in hydrophobic subnanometer channels in general and SONPs in particular, we perform a series of ab initio molecular dynamics simulations to investigate the diffusivity of aqua Na+ and K+ ions in two prototype hydrophobic nanochannels: (i) an SONP with radius of 3.2 Å, and (ii) single-walled carbon nanotubes (CNTs) with radii of 3–5 Å (these radii are comparable to those of the biological potassium K+ channels). We find that the hydration shell of aqua Na+ ion is smaller than that of aqua K+ ion but notably more structured and less yielding. The aqua ions do not lower the diffusivity of water molecules in CNTs, but in SONP the diffusivity of aqua ions (Na+ in particular) is strongly suppressed due to the rugged inner surface. Moreover, the aqua Na+ ion requires higher formation energy than aqua K+ ion in the hydrophobic nanochannels. As such, we find that the ion (K+ vs. Na+) selectivity of the (8, 8) CNT is ∼20× higher than that of SONP. Hence, the (8, 8) CNT is likely the most efficient artificial K+ channel due in part to its special interior environment in which Na+ can be fully solvated, whereas K+ cannot. This work provides deeper insights into the physical chemistry behind selective ion transport in nanochannels. Studying dynamics of ion channels © 2015 Phys.org To that end, Hui Li, Joseph S. Francisco, and Xiao Cheng Zeng from Chinese Academy of Sciences and from the University of Nebraska in Lincoln have elucidated some of the mystery behind ion selectivity using molecular modeling of these synthetic ion channels made of rigid macrocycles as well as channels made of carbon nanotubes. They used ab initio molecular dynamics simulations to investigate solvation structures, energetics, and dynamic properties of aqua Na+ and K+ in synthetic organic nanopores (SONP) and various sizes of single-walled carbon nanotubes (CNTs). Their work is published in the Proceedings of the National Academy of Sciences.Prior simulation studies with synthetic ion channels have focused predominantly on Lennard-Jones potentials and Columbic effects. This is a reasonable area to investigate since researchers are trying to discern ion selectivity. These investigations pointed to the channel radius as the predominant factor for potassium selectivity. However, Li, et al. wanted to look at computations at the quantum-mechanical level to better understand water molecule interactions within a confined environment.

Bratya Basu’s literary invasion into the near-death experience (NDE) is a twist in the tale of otherwise a gripping story of soul searching of a fatally injured man in the coma. The playwright chooses a middle-class Bengali protagonist who represents the perception of the entire class about their daily chores, ambitions, accomplishments, failure, wiliness, inherent family politics and their rationale to defend themselves in their lives.The play progresses lyrically by dissecting the mind of the protagonist and constructing the discourse of a common man in the society who struggles hard in balancing between building his career and struggling for a satisfactory family life. He stumbles quite often to get up again and move on. His vices and dogmas are generally criticised hard in his society but he shows the courage to confront them. ‘Ami Anukulda ar Ora’ is a short play which blends the real with surreal, moves between likelihood and implausibility, revolves around dreams and reality of a commoner by indicting and challenging the social system. Also Read – Add new books to your shelfAvi Chakraborty of Asoknagar Natyamukh has shown noticeable maturity in producing a difficult play. He has skillfully brought OBE (out of the body experience) on stage to handgrip the enormity and spread of introspection. Somesh, 54 years of age, a marketing manager of a private firm, meets with a serious accident and slips into unconsciousness with a little chance of recovery. It is in this condition that reality and dreams cross boundaries when his friend of yesteryears, Anukulda, comes to visit Somesh. We see Somesh in his teens in dialogue with Anukulda, whose nagging and blunt behavior irks him but reminds him of his nostalgic past. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe most poetic, emotive and surrealistic part of the play happens when his unborn, aborted daughter who if born would have been a teenager, comes to visit him to remind Somesh of his complex intimate relation with his wife. The playwright’s creative resourcefulness brings the kindliness of a father-child conversation which silently makes the Electra complex perceptible between them. In the concluding part, Somesh faces ‘Godot’ of Samuel Beckett where he admits that while he might have faced ‘Iblish’ to experience ‘hell’ on earth, he still wishes to live for a minority few for whom it is worth living. Charming Rishav Basu as Somesh is very good in his role in the play. He, with his impressive diction and gracious body movement, carries the play effortlessly on his shoulders as a protagonist. Equally dexterous is Sumanta Roy in his role as Anukulda. He challenges Rishav quite often with his natural acting and undoubtedly proves his potential as an actor of promise. Avipsa Ghosh as Somesh’s daughter shows her growing determination to be a great actor on stage. Sandipan Chatterjee is good in his role as God. Director, Avi Chakraborty, keeps the stagecraft simple where he demarcates the frontal part of the stage to perform the out of the body experience and the rear part as the Nursing home, the reality. The transportation from conscious to the subconscious is subtle and is done aesthetically. Special mention of Saumik Chakraborty is required here for his fascinating set design. Music and background score of Dishari and Light designing by old-timer Sudip Sanyal make the production complete. The playwright’s elucidation of the importance of an employed middle-class life with values and contradictions amidst negativities in the world brings a wave of fresh air for us to inhale deep and take our lives forward.
