The Regional Cultural Centre, Letterkenny will be the venue for launching an ambitious new anti-racism programme Show Racism the Red Card on March 14th.Many Donegal schools and youth services will be familiar with this programme because of work by Finn Harps FC in promoting the message of Show Racism the Red Card.The launch will include the unveil of a new DVD education pack featuring Seamus Coleman and pupils from St Eunans National School in Raphoe. This new education pack includes a DVD which is 18.41minutes long and features top stars of Irish sport including Donegal’s Seamus Coleman alongside his international teammates Simon Cox, David Meyler, James Mc Carthy, David Meyler, Darren Randolph and Sean St Ledger.Ireland women’s U19 Rihanna Jarrett also features as do some of the stars from rugby and GAA including Gaelic Players Chief Executive Dessie Farrell and Wexford’s Lee Chin.The DVD is a lively feature including action footage from the stars of the different sports. Also featuring are children from St Eunans National School Raphoe.The example of action taken by children at St Eunans National School is being highlighted as good practice for schools all over Ireland. In creating their mosaic of Show Racism the Red Card mascot Jeff the Ref, the children at St Eunans involved the endorsement of the great and the good from Donegal and beyond, who signed the cards which make up the mosaic. The teachers and children at St Eunans have worked hard over recent years in support of Show Racism the Red Card.The DVD will be accompanied by a 36 page pack, with lots of activities to support learning in the classroom. The pack will be translated into Irish to ensure usage in Gaelscoilleanna and Gaeltacht schools. The pack features activities which are downloadable and encourage interactive learning that young people can enjoy.DONEGAL GETS READY TO SHOW RACISM THE RED CARD was last modified: March 6th, 2013 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:DONEGAL SPORTS PARTNERSHIPRaphoeShow Racism the Red CardSt Eunan’s NAtional School
Over the past four years, lawmakers have come up with multiple reasons to reject the Pentagon’s request to hold one or more rounds of base closures, but none of them have held up under scrutiny, especially as DOD faces severe spending constraints, says Mackenzie Eaglen, a resident fellow at American Enterprise Institute.“Congress has dug in for too long on opposing the long-overdue next base closure round. The irony is that this is hurting communities and the military — not helping them, contrary to popular opinion,” Eaglen writes in a commentary published in Forbes.The argument that BRAC does not save money is refuted by the $12 billion the first five rounds are saving annually, she writes. Even the 2005 round, with its emphasis on realigning missions rather than closing facilities outright, is saving $4 billion each year.Lawmakers’ insistence that the department conduct an “overseas BRAC” before pruning its domestic infrastructure ignored the progress all three services have made in shrinking their footprint in Europe over the past 10-plus years as the U.S. presence overseas has been significantly curtailed.The latest rationale for rejecting the administration’s request is that the ongoing drawdown of the armed forces may need to be reversed and, as a result, the department will need more space to accommodate its personnel.“But here again, the numbers just don’t add up,” Eaglen writes. Even if a hawkish administration captures the White House in November, the size of the armed forces is unlikely to grow by more than 4 percent.“[That] does not make a dent in the argument for why over 20 percent excess infrastructure cannot still be reduced to more manageable levels,” Eaglen states.While Congress believes it is protecting defense communities by resisting a new BRAC round, “the hundreds of defense communities across America with a military presence are strongly on the record in favor of outright base closures over the slow bleed that is currently hollowing out many posts and bases from within,” she writes.“Inaction and uncertainty is actually worse than the potential for bad news in the overwhelming majority of communities affected,” according to Eaglen’s commentary.She concludes that it’s time for lawmakers to “finally start to listen to what is best for the U.S. military, the taxpayer, and the constituents back home when it comes to base closures.” Dan Cohen AUTHOR
The research group then tested whether yellow pulses occur at certain stages of feather tract differentiation by staining developing follicles with beta-catenin. Their results indicated that these pulses were not related to any mechanism taking place during tract formation, so they next examined whether the pulses were triggered by feather growth. Finding no correlation between feather growth and yellow pulses, the investigators then theorized that the yellow pulses are governed by prepatterns established before skin differentiation, and governed by the signalling peptide Agouti. They ultimately found that agouti-expressing bands are present in the dermis prior to follicle formation, and that these bands foreshadow the position of the yellow stripes. They confirmed their findings by performing a double in situ hybridzation for agouti and beta-cateninin the species Coturnix japonica.To further demonstrate the relationship between agouti and the yellow pulse, the researchers looked at the striped phenotype in mutant strains of C. japonica. Examining recessive black quails (RB-/-) and fawn quails (FA-/-), they compared differences in phenotypes with genetic data related to the expression of agouti and the duration of the yellow pulse. They found that the agouti gene directly controls stripe width in a dose-dependent manner via the duration of the yellow pulse. On these findings they conclude: “This raises the appealing possibility that striped pattern evolution is governed by differential regulation of agouti expression levels.”Finally, in a grafting experiment designed to determine whether the somitic mesoderm controls agouti expression and stripe position, the researchers transplanted somites and neural tubes from the right side of C. japonica onto the right side of P. colchicus. They used immunohistochemistry staining with QCPN to track cell growth and development from the grafted section, and track expression of Trp1, a marker for black pigment generating melanocytes. The result of their operation was a chimera whose right side showed the phenotypic characteristics of the C. japonica donor, thus demonstrating that the localized expression of agouti and the associated pigments are governed autonomously by the somitic mesoderm.The authors of this study thusly conclude that the striped pattern in birds is governed by a two-part mechanism. First, the somite determines the location and positioning of agouti-expressing bands in the dermis through the establishment of a prepattern. Then, the prepattern is further elaborated on with respect to the differing levels of expressed agouti, which in turn determine the width of each stripe. “These results,” the reasearchers write, “raise the possibility that most natural patterns, including periodic designs, rely on (and are constrained by) a stepwise organization of space that combines late local events producing periodicity and early positional sources ensuring reproducibility, which is the key to fitness and proper directionality (in this case, longitudinal stripes depend on information from axial structures).” More information: Haupaix et al.

DOI: 10.1126/science.aar4777 Citation: What’s behind the color and pattern of bird feathers? (2018, September 26) retrieved 18 August 2019 from https://phys.org/news/2018-09-pattern-bird-feathers.html To better understand the phenomenon of feather patterning and coloration, a group of French researchers led by Nicolas Haupaix undertook a study of galliform birds. In looking at an initial group of 10 species, the researchers sought to deterimine whether or not early developmental landmarks play a role in establishing spatial reference for periodic patterns in feathering. They identifed two main types of feathers among these species: entirely black (eumelanic) and yellow (a black base and tip, with a central yellow [pheomelanic] band in between). Henceforth, they were able to establish a common stripe sequence emanating from the dorsal midline: a central black stripe, sometimes containing a few yellow feathers, flanked on either side by a yellow stripe, each of which was bordered by another black stripe, which in turn was borderd by another yellow stripe.From this, the researchers observed that an increase in dorsum size correlated with an increase in stripes, suggesting that color pattern variation is not necessarily the result of scaling. In fact, in measuring absolute distances between groups of stripes, they were able to infer that stripe position is determined early, before the skin expands. The researchers also found, by plotting feather tracts in relation to stripe boundaries, “that color boundaries are highly reproducible within species,” but that these boundaries vary between species in relation to stripe width and stripe shape, suggesting that the variations in width and shape are due to local effects present during feather tract formation.Working from these findings, Haupaix and colleagues examined pigment production and feather tract formation during embryogenesis in five galliform species, each representative of distinctive variations in the width and shape of stripes and the organization of the dorsal tract. They found that pigment production begins a few days before hatching, when all dorsal tract feather follicles are visible. The black central feathers are colored first with eumelanin, the default tissue pigment, which is then succeeded by a “pulse” of pheomelanin. This forms the banded yellow pattern of the lateral feathers. This phase is then succeeded by a return to eumelanin production for the farthest lateral feathers and transient production of pheomelan, in the case of birds with a central yellow stripe. Journal information: Science © 2018 Phys.org While it may be true, as the old adage goes, that ‘birds of a feather flock together,’ what is less certain is how the feathers on those birds come to have their distinct patterns and colorations. Current data suggest that patterns of stripes and spots on animals’ fur or feathers are formed through an open-ended or stochastic process during the embryonic formation of skin, at which time a dynamic—such as Turing’s reaction-diffusion—is at play. On the other hand, owing to their specific orientation and periodictity, and the highly reproducible nature of these patterns within species, it is thought that other factors may also be at work in the development of patterning and coloration.

Kolkata: A youth was shot at on Beliaghata Main Road on Thursday morning.Police said the youth, Danish, received bullet injuries and is admitted to hospital.Policemen from Narkeldanga Police Station went to the spot after receiving information in this connection.Police came to know, after speaking to locals, that three youths came on a motorbike and all of a sudden, started firing at Danish, who received bullet injuries.Hearing the sound of bullet shots, locals rushed to the spot and found Danish lying in a pool of blood. Police with the help of locals took him to NRS Medical College and Hospital where he is receiving necessary treatment.Police initiated a probe in this connection and collected samples from the spot.They have also spoken to the locals to know if anyone knew the three persons who came on motorbike.A police officer said it seems there are some locals who are involved in the entire operation and suspect that the same person had informed the trio that Danish was waiting for someone on Beliaghata Main Road. Police are yet to ascertain the exact reason behind the incident, but suspect that an old rivalry had led to the crime. They are speaking to Danish’s family members to know if he was involved in a dispute with anyone in the recent times.In a bid to identify the trio involved in the incident, police are going through the footages of CCTV cameras installed in the area. The incident led to panic in the area and policemen have been posted and are taking necessary steps to check repetition of such incidents.
