G$ contains a set $S$ of at most $k$ vertices such that $G\setminus S$ belongs to ${\cal G}.$ We denote by ${\cal A}_k ({\cal G})$ the graph class containining the graphs that are $k$-apices of ${\cal G}.$ We prove that every graph in the obstruction set of ${\cal A}_k ({\cal G}), $i.e., the minor-minimal set of graphs not belonging to ${\cal A}_k ({\cal G}),$ has size at most $2^{2^{2^{2^{poly(k)}}}},$ where ${poly}$ is a polynomial function whose degree depends on the size of the minor-obstructions of ${\cal G}.$

Exponential Independence in Subcubic Graphs
A set $S$ of vertices of a graph $G$ is exponentially independent if, for every vertex $u$ in $S$, $\sum_{v∈S\setminus \{u\}}(1/2)^{{\rm dist}(G,S) (u,v)−1} < 1$, where ${\rm dist}(G,S)(u, v)$ is the distance between $u$ and $v$ in the graph $G − (S \setminus \{u, v\})$. The exponential independence number $αe(G)$ of $G$ is the maximum order of an exponentially independent set in $G$. In this work we present several bounds on this parameter and highlight some of the many related open problems. In particular, we prove that subcubic graphs of order n have exponentially independent sets of order $Ω(n/\log^2 (n))$, that the infinite cubic tree has no exponentially independent set of positive density, and that subcubic trees of order n have exponentially independent sets of order $(n + 3)/4$.

Kernelization of Maximum Minimal Vertex Cover
In the Maximum Minimal Vertex Cover (MMVC) problem, we are given a graph $G$ and a positive integer $k$, and the objective is to decide whether $G$ contains a minimal vertex cover of size at least $k$. This problem has been considered in several articles in the last years. In this talk we focus on its kernelization, which had been almost unexplored so far. We prove that MMVC does not admit polynomial kernels parameterized by the size of a minimum vertex cover or of a maximum matching, unless NP⊆coNP/poly. Motivated by a question of Boria et al. (Discret. Appl. Math. 2015) about the existence of subquadratic kernels for MMVC parameterized by $k$, we rule out their existence unless P=NP, if we restrict the kernelization algorithms to apply only a type of natural reduction rules that we call large optimal preserving rules. In particular, these rules contain the typical reduction rules to obtain linear kernels for Vertex Cover. On the positive side, we provide subquadratic kernels on $H$-free graphs for several graphs $H$, such as the bull, the paw, or the cliques, by making use of the Erdős-Hajnal property in order to find an appropriate decomposition.

On the complexity of computing Maximum Minimal Blocking Sets
A blocking set in a graph $G$ is a subset of vertices that intersects every maximum independent set of $G$. Let 𝗆𝗆𝖻𝗌($G$) be the size of a maximum (inclusion-wise) minimal blocking set of $G$. This parameter has recently played an important role in the kernelization of Vertex Cover parameterized by the distance to a graph class ${\cal F}$. Indeed, it turns out that the existence of a polynomial kernel for this problem is closely related to the property that 𝗆𝗆𝖻𝗌$({\cal F})=sup_{G∈F}$𝗆𝗆𝖻𝗌$(G)$ is bounded by a constant, and thus several recent results focused on determining 𝗆𝗆𝖻𝗌$(F)$ for different classes $F$. We consider the parameterized complexity of computing 𝗆𝗆𝖻𝗌 under various parameterizations, such as the size of a maximum independent set of the input graph and the natural parameter. We provide a panorama of the complexity of computing both 𝗆𝗆𝖻𝗌 and 𝗆𝗆𝗁𝗌, which is the size of a maximum minimal hitting set of a hypergraph, a closely related parameter. Finally, we consider the problem of computing 𝗆𝗆𝖻𝗌 parameterized by treewidth, especially relevant
in the context of kernelization. Given the "counting" nature of 𝗆𝗆𝖻𝗌, it does not seem to be expressible in monadic second-order logic, hence its tractability does not follow from Courcelle's theorem. Our main technical contribution is a fixed-parameter tractable algorithm for this problem.

On the colorability of rectangle intersection graphs
Chalermsook and Walczak proved that rectangle intersection graphs with clique number $w$, are $O(w\cdot\log w)$-colorable. This improves on the $O(w^2)$ bound dating from 1960. They also designed a deterministic polynomial-time $O(\log \log n)$-approximation algorithm for the same problem. This improves on previous known algorithms. This talk will be devoted to the description of these results.

A matching theoretic approach to structural digraph theory
The theory of butterfly minors in digraphs which is closelinked to the notion of directed treewidth has become an active field of research in the past years. Many great advancements have been made such as a directed version of the famous Grid Theorem and several other generalisations of great results from the Graph Minors Series of Robterson and Seymour.
However, many of these results appear flawd when first encountered: The Erdős-Pósa property of butterfly minors does not appear to be linked to a topological property, and the directed version of the Flat Wall is not actually flat.
In this talk we identify two possible reasons for these flaws and show how recent advancements in the area of structural matching theory can be used, by rethinking the way we handle butterfly minors and unavoidable infinite anti-chains of them, to achieve much nicer results.

Complexity thresholds for fractional distributed colouring
In the domain of distributed algorithms, the complexity is considered in terms of rounds, during which the nodes of a graph can exchange data with their neighbours. Moreover, in the LOCAL model, the nodes are assumed to have infinite computational power, so any problem can be solved within D rounds, if D is the diameter of the graph. When considering distributed colourings of graphs of fixed maximum degree Δ on n vertices, an interesting complexity threshold appears. There exists a deterministic distributed algorithm for finding a colouring with Δ+1 colours within O(log* n) rounds. If the graph is neither complete nor an odd cycle, Brooks' Theorem tells us that there exists a colouring with Δ colours. It turns out that any distributed algorithm constructing such a colouring requires Ω(log n) rounds if it is deterministic, or Ω(log log n) rounds if it is probabilistic.
In this talk, I will present a similar sharp threshold for the complexity of distributed fractional colourings of graphs of fixed maximum degree, and of d-dimensional grids. Finally, I will present a distributed algorithm for constructing a fractional colouring of weight 2+ε of graphs of maximum average degree 2+ε' and sufficiently large girth, within O(log n) rounds.

Query enumeration and nowhere dense classes of graphs
Given a query q and a graph G the enumeration of q over G consists in computing, one element at a time, the set q(G) of all solutions to q on G. The delay is the maximal time between two consecutive output and the preprocessing time is the time needed to produce the first solution. Ideally, we would like to have constant delay enumeration after linear preprocessing. Since this it is not always possible to achieve, we need to add restriction to the classes of graphs and/or queries we consider.
In this talk I will talk about some restrictions for which such algorithms exist: graphs with bounded degree, tree-like structures, conjunctive queries...
We will more specifically consider nowhere dense classes of graphs: What are they? Why is this notion relevant? How to make algorithms from these graph properties?

to using resistivity contrast instead of acoustic impedance contrast.
 direction at right angles to this axis. On real, logs check heading carefully, as travel time and amplitude images can be interchanged in position, and North may be on the right or the middle of the track.
Determining Fracture Orientation
As mentioned above, when formation pressure is isotropic (equal in all directions), the tectonic stress is zero and Pfrx equals Pfry. In this situation, the borehole is round and spalling of the formation is either non-existent or equal in all directions. In stressed regions, such as in the Rocky Mountains, the borehole will erode to an oval shape. The minimum diameter shows the direction of maximum stress and the maximum diameter shows the direction of minimum stress..
Borehole shape indicates stress direction – maximum stress in direction of minimum hole
 diameter. Formation microscanner and dipmeters have oriented caliper data.
Many modern logs have an X and Y axis caliper, but not all of them are oriented to true north. When directional data is recorded, as with dipmeters and many modern resistivity tools, the X and Y orientations are known, Statistical plots are helpful in choosing the dominant direction).
Borehole diameter indicates stress direction - this example is from India where the minimum
 stress direction is NE - SW.
A hydraulic fracture will usually penetrate the formation in a plane normal to minimum stress, or parallel to the plane of maximum stress. Any stress anisotropy (tectonic stress) will cause the fracture to be other than vertical.
Natural fractures take the same directions as hydraulic fractures, indicated again by the borehole shape. In addition, the high angle dips seen on an open hole dipmeter or image log, will also indicate this preferential direction. Since most hydraulic fracture jobs are run in casing, it is not possible to run a dipmeter or caliper survey to find the orientation of a hydraulic fracture. The preferential direction can be predicted from previous open hole data. Dipmeter and caliper data can be displayed on rose diagrams to illustrate preferential directions.
If an azimuthal gamma ray log existed, the fracture orientation could be located by a tracer survey. I am not aware that such a tool exists, but it would not be difficult to design one..
<== Azimuth frequency (rose diagram) plots show direction of dips seen on dipmeter and image logs. When steep dips caused by fractures are isolated from lower angle bedding dips, the direction of maximum stress xan be determined. In this case, the direction is N30E.
Stress direction is not constant over geological time scales. Differences in the direction of induced fractures (present day stress direction), open fractures (some time ago), healed fractures (older than open fractures), and small faults (could be any age) will help to show the stress history of a region. An example log and rose diagrams are shown below.
Image log in fractured reservoir: gamma ray (left track, shaded red), image track (middle) with open fractures (red sine waves and healed fractures (yellow sine waves), dip track (right) shows red amd yellow dip angle and azimuth. There are no induced fractures in this short interval. Bedding planes are near horizontal. Imagine trying to locate these steep dips without the aid of a computer.
Induced fractures (top left) show current stress direction. Open fractures (top right) show stress direction when fractures were created, healed fractures (lower left) show different direction at an earlier phase in geological time, and micro faults (lower right) shows another stress regime was present when the faults occurred.
The newest dipole shear sonic log is also an azimuthal tool with dipole sources set at 90 degrees to each other. The example below shows the shear images for the X and Y directions. This log can be run in open or cased hole.
Dipole shear image log shows directional stress - the Fast Direction is centered on
90 degrees (east - west) which is also the maximum stress direction.


Ooze Tube
picture of ooze tube
This toy will mesmerize you. When inverted, the gooey fluid flows down slowly from top to bottom. Watch as the fluid begins to flow down, and touches bottom, and from there it gradually piles up. As the name suggests, it oozes down. This slowly moving fluid is called, in physics terms, highly viscous, because of how slowly it flows from one place to another. Water, on the other hand, is much less viscous because of how much easier it flows from one place to another. The viscosity of a fluid is a measure of its resistance to gradual deformation. Viscosity is due to the friction between fluid particles as the fluid moves.

Im Rahmen von: SCORES N°11 / / Atelier EDN - European Dancehouse Network: ARCHIVES TO COME
Anyone who puts "materials" into an archive, anyone who archives, lays down traces. These again (perhaps) are followed by others, so that in their present they lend a future to the past by writing hi/stories. The "archive" as an institution and "archiving" as a practice are booming (both scientifically and artistically). But what do these shimmering terms "contain"? They designate a historical corpus as much as the movements that open it up, insofar as they (also) start from the body of the user. They thereby have concrete, metaphorical and in both senses a corporeal meaning.
This talk aims to address both a terminological discussion as well as a positioning of the archive/archiving between subject and object, between times and classification of times, between constancy and process; it aims to address questions of power and status, and, finally, the dance specifics on this debate as well as visions from the perspective of dance studies.

Floating Point Rounding
From Erlang Community
You need to round a floating-point number to an integer.
Use one of the functions round/1, ceiling/1, floor/1 and trunc/1. Note, the standard Erlang distribution does not come with either floor/1 or ceiling/1, but they can be easily implemented in terms of trunc/1
floor(X) when X < 0 -> T = trunc(X), case X - T == 0 of true -> T; false -> T - 1 end; floor(X) -> trunc(X). ceiling(X) when X < 0 -> trunc(X); ceiling(X) -> T = trunc(X), case X - T == 0 of true -> T; false -> T + 1 end. 1> floor(-4.3). -5 2> ceiling(-4.3). -4 3> trunc(-4.3). -4 4> round(-4.3). -4 5> floor(3.5). 3 6> ceiling(3.5). 4 7> trunc(3.5). 3 8> round(3.5). 4 9> round(7). 7
The procedures all return integers.
round/1 returns the closest integer to x, rounding to even when x is halfway between two integers. trunc/1 returns the integer closest to x whose absolute value is not larger than the absolute value of x. floor/1 returns the largest integer not larger than x. ceiling/1 returns the smallest integer not smaller than x.
For the floor and ceiling functions implemented above, T will always be less than or equal to X. We just need to check if there is a difference between the two in which case we will either increase or decrease the truncation depending if we want to floor or ceiling X.
(Correction to floor/1 and ceiling/1 to check for negative or positive values. 2009-11-21 seetho)

Salmon Lake Dam is an earthfill structure 54 feet high, and has a volume of 195,000 cubic yards. The total active reservoir capacity of Conconully Lake is 15,700 acre-feet (active 10,500 acre-feet). The spillway is a siphon type with a capacity of 400 cubic feet per second. The outlet works is a conduit controlled by two gates. A small diversion headwords structure on Salmon Creek diverts the flow into the reservoir through a short feeder canal.
In July 1998, a reservoir operating restriction to elevation 2314 feet was imposed on Conconully Lake as an interim risk reduction measure pending structural modifications to address seismic safety concerns. This reduces the active reservoir capacity to 7,400 acre-feet.
Salmon Lake Dam is founded on the left abutment against rock. The embankment dam across the valley floor and in the right abutment is founded in such materials as silt, sand and gravel, including boulders. The outlet works and spillway are founded on metamorphic sedimentary rock (gneiss).

Here a non-parametric estimate of the number of penguins occupying Summerland Beach, Phillip Island, Australia, was computed. This estimator did not assume equal catchability of individuals, did not assume a parametric form for the population size as a function of time and allowed individuals to leave and re-enter the population.

Did you know that the food our kids eat can play a crucial role in shaping their behaviour?
Food can even address aggressive behaviours like bullying?
A recent study, the 2019 Canadian Health Survey on Children and Youth (CHSCY), shed light on a concerning statistic – a whopping 71% of Canadian adolescents aged 12 to 17 reported encountering bullying in the past year. Bullying, whether it's physical, verbal, or emotional, has far-reaching consequences on social, physical, and mental well-being.
Let's look at an exciting solution to address children's aggressive behaviours through nutrition!
Nutrition & Bullying
What if I told you that nutrition can make a difference here?
Research suggests that implementing prevention programs, with a focus on supplementation or improved nutrition, can be a game-changer.
Picture this: in juvenile correctional institutions, adopting nutrient-dense diets aligned with World Health Organization guidelines led to a jaw-dropping 50% reduction in violence and antisocial behaviour. Now, don't get me wrong; I'm not saying we should turn our homes into mini correctional facilities. But the connection between nutrition and behavior is too fascinating to ignore!
And guess what: These positive outcomes extend beyond correctional facilities to our regular school-going kiddos aged 6-12.
The Power of Childhood Nutrition
In a fascinating study, school-aged kids who received low-dose vitamin-mineral tablets showed significantly less violence and antisocial behaviour compared to those given placebos.
This highlights the potential of supplementing with a good multivitamin to address antisocial and aggressive behaviours in our school-aged children. It's not just about boosting vitamin concentrations in their blood; it's about enhancing brain function, leading to a nearly 50% decrease in institutional violence and antisocial behaviour.
To sum it up, we've got a powerful tool in our hands – nutritional interventions.
Addressing Aggressive Behaviours
If we want to tackle bullying, we need to recognize the pivotal role of nutrition. Research strongly supports the significant impact of supplementing with essential vitamins and minerals, providing a cost-effective opportunity to reduce aggression and violence in both correctional institutions and regular school environments.
So, let's work together to foster healthier relationships and creating safer school environments for our incredible youth. Because when it comes to our kids, every little step toward a brighter future matters.
Recommended Nutrients / Vitamins for Kids 3-12:
The study mentioned above gave the inmates a daily multivitamin and an omega-3 supplement that contained about 50% of the RDA for 4 weeks. Here are some great multivitamins and omega-3 options for you to try at home:

The Council for Scientific and Industrial Research (CSIR) has developed a lighter, cheaper and more compact version of its Otus surveillance camera, which is currently being used to detect poachers in the Kruger National Park.
The CSIR's new Tyto camera, which is a spinoff off Otus, is designed for wide area surveillance for applications like border security or asset protection. Whereas Otus has two channels of view, Tyto has one, making it lighter and cheaper – Tyto weights 20 kg compared to the 98 kg of Otus, and is 58 cm long compared to 80 cm.
Otus and Tyto are developed using commercial off the shelf optical components, enclosed in a custom housing. The system operates using software developed by the CSIR.
Tyto is able to operate during the day or at night with enhanced twilight performance. It has a high sensitivity monochrome main sensor and thermal detection sensor. The day camera has a 30 times optical zoom. Range is around 5 km, compared to approximately 10 for Otus.
Otus is the camera on the Meerkat wide area surveillance system that adds a Reutech radar. It has been used in the Kruger National Park to spot rhino poachers with considerable success. Like Otus, Tyto can also be integrated with a radar system.
At the moment the CSIR is doing feasibility testing of the camera system. While Otus is a mature product, Tyto is a niche market product still under development.
Aside from onsite laboratories and facilities used in the development of optronic products, the CSIR said it is geared to undertake pilot deployments in the field with mobile containerised control and evaluation units.
The CSIR said its cameras are ideally suited for day and night surveillance of high value assets, including for wildlife conservation, state-owned entities/infrastructure and border management.

BTWSC in association with African Histories Revisted, focus their two 2013 NARM African British histories on commemorating the 50th anniversary of the Paul Stephenson-led Bristol Bus Boycott, and the 100th anniversary of the election of London's first African mayor John Archer.
Although the audio-visual presentations can be delivered separately for youths, adults and inter-generational audiences, the programme launches at Gayton library with a combined presentation. It consists of:
1. Paul Stephenson & The Bristol Bus Boycott
An audio-visual presentation led by history consultant Kwaku with primary source material highlighting the fact that there was a bus boycott in Britain in 1963. It's an accessible family-friendly presentation, which will also point out the connections with cricket, the first race relations law, Tony Benn, newly "independent" Caribbean states, and Martin Luther King's 'I Have A Dream Speech'.
2. John Archer & Black Politics
An audio-visual presentation led by history consultant Kwaku that goes beyond the fact that John Archer became London's first African mayor in 1913. It's an accessible family-friendly presentation, which will show that besides being a councillor, he was a Labour party activist whose successful collaboration with an Asian parliamentary candidate sowed the seeds of the party's Black Sections over half a century earlier. An attendee of the 1900 pan-African conference, he was talking about issues such as reparations, long before it took hold in the 1990s.

Multiplexed gallium–arsenide (GaAs)-based terahertz (THz) emitters fabricated with periodic double-metal structures are demonstrated and the effect of different metals on the THz output is investigated. THz emission originates from the lateral photo-Dember effect and from the different Schottky barrier heights of the chosen metal pair. The metal combinations used were Au–Al, Au–Pb and Cu–Cr. The emitters were characterised according to temperature and the highest peak-to-peak THz emission was achieved with the Cu–Cr metal pairing at 150 K.

text: The precipitation-radar images show only qualitative information on precipitation.The radar images are based on non-processed raw data. Their quality is limited to non-quantitative information, since radar is only an indirect method of measuring precipitation, based on reflectivity. Quantitative information from radar measurements is obtained by comparing the data with conventional precipitation measurements. However, real-time measurements aren't possible yet. This so-called quasi-calibrated data is neither produced regularly nor updated. For different technical reasons radar information is still incomplete and patchy. The spatial resolution of the precipitation radar image is 4 km x 4 km and the temporal resolution is 15 minutes. Based on the magnitude of radar reflection seven different intensities of precipitation were distinguished.

The structure and scoring of the original 30-item MMSE have been retained while problematic items have been replaced. The three words for the Registration/Recall tasks have been made slightly more difficult and were revised to make foreign language translations easier. The phrase for the Repetition task has been changed to facilitate its translation into foreign languages, enabling easier comparison of results across all language versions. The Comprehension task has been altered to make it easier for persons with physical limitations to perform. Because the difficulty of the MMSE-2:SV, along with its raw score range, remains the same as the original, scores obtained using the original MMSE and scores obtained using the MMSE-2:SV are comparable.
The MMSE:SV Kit includes the MMSE-2 User's Manual, 25 MMSE-2:SV Blue Forms, 25 MMSE-2:SV Red Forms, 10 MMSE-2:BV Blue Forms, 10 MMSE-2:BV Red Forms, and the Pocket Norms Guide.

Whenever there is no service while using live tracking, all the points in between losing Internet connection and regaining it are gone. It would be great to have an option to send all cached points once a connection is back. As they can be timestamped, it should not be a problem for receiving servers to parse the points. They could be sent in an array, for example.
Local caching for live tracking when out of data signal
Would it be possible to add local caching to the live tracking so locations are sent from when the phone is out of data signal?
For implementation I envisage it working something like:
- In a live tracking profile, users can opt to use caching
- Caching is unavailable for GET requests (as data length is limited and you do not want to poll a url multiple times in a short time)
- For POST requests, Locus sends (if data available) a cache variable which is an array of locations (in the same format as the live beacon).
On the receiving server:
- any local authentication etc.
- process live location
- check for cache variable
- if present and supported, process cached locations
As an extra bonus, Locus could detail how many cached locations are stored in notifications (with where it currently reports successes and failures), and provide a way of manually sending the data to the server (example is when you finish a walk out of signal - you stop the tracking, but want to share the outstanding locations when you are back in signal.)

Paris – With 108 years worth of stories, the elegant Hôtel Lutetia was the lodging of choice of Matisse, Camus and the crème de la crème of the Saint-Germain society – it was, after all, founded by the family that also created the equally admired Le Bon Marché. And now, after a massive four-year renovation, it opens its doors again. Architect Jean-Michel Wilmotte took his time with the details, even commissioning bespoke pieces and finishes. One of those items was the Lutezia tap collection, created by Vicenza-based manufacturer CEA.
In the name of accuracy, the project required merging Art Deco and Art Nouveau elements, to reflect the heritage of more than a century's worth of style influences. 'Our project research included great attention for the ergonomics of the handle and the proportion of the water flow,' stated Roberta Bertacco, co-founder and managing director of CEA. Their main source of inspiration, though, was an unexpected element: the hydraulic valve of the radiators from the late-eighteenth and early-nineteenth centuries. And now, the bathrooms of the 184 units, the common spaces and the spa feature the delicately curved yet sturdily resistant pieces, in silver and rose shades inspired by the Parisian Belle Époque.

Planning a Medium-Deep Water Mooring for Small Data Buoys
Note: NexSens Technology supplies mooring hardware to support user-designed systems but does not endorse any particular mooring strategy for any specific application and does not take responsibility for mooring performance or damage resulting from mooring failure.
Medium-Deep Water Deployment Considerations
While many medium-deep water (>100m depth up to approx. 1000m depth) monitoring projects require large buoy platforms due to sensor loads and corresponding power requirements, there may be some cases where a smaller buoy platform is desirable. This can facilitate measurements from a small package of power-efficient sensors where only near-surface (<50m) measurements are required and provide a solution that is easier to lift and handle by project personnel.
By small data buoys, we are generally referring to CB-Series buoys up to and including the CB-450 model. While these are small and light enough to lift manually by 1-2 persons depending on the model, a medium-deep water mooring system will generally have a sizable anchor weight. As such, a suitable vessel equipped with winch and crane is strongly recommended for lifting and controlled release of equipment to avoid injury to personnel or damage to equipment.
Whereas two-point moorings with suspended sensor lines are often a viable option for shallower applications, medium-deep water moorings will typically be single-point due to the required mooring line length. This means that suspended sensors will be mounted along the primary mooring line, and special care must be taken in the design to ensure that twisting or stretching of data cables does not take place, as this can lead to failure even within a short timeframe.
Some general suggestions and points for consideration when planning this type of deployment are described in the following sections:
Mooring Line Length and Drift Radius
In order to determine the appropriate mooring line length, it is first necessary to have a fairly accurate water depth measurement at the deployment site and overview of the expected water level changes. In most applications, mooring line lengths should be ~50% greater than the median water depth to account for water level fluctuations.
The potential drift radius of the buoy, determined by the water depth and mooring line length, is important to calculate to understand if the mooring line will work for the application. The maximum drift radius can be theoretically calculated using Pythagorean theorem as illustrated in the diagram below and using the following formula:
While this is only a theoretical calculation which may vary in an actual deployment, especially depending on the physical properties of the mooring line, it can serve as a basis for determining the total mooring line length (also see Mooring Hardware Materials). Too large of a drift radius may result in the buoy coming into conflict with the shore, infrastructure such as docks, or ship traffic. However, a mooring line that is too short can put the buoy at risk of submersion from horizontal loading during high wave and current conditions. The diagrams below illustrate this effect.
A general principle is that the buoy should be allowed to move somewhat freely with waves and currents rather than attempting to firmly hold it in place at an exact point. How much drift radius can be tolerated must first be determined, and then the total mooring line length can be calculated.
Chains for Controlled Movement vs. Ballast Weight
One strategy to provide an adequate potential mooring line length but provide some limitation on the buoy's free movement is to use a heavy bottom chain as a part of the mooring system. The idea of the heavy bottom chain is that it can be lifted up from the seafloor as the buoy is pushed away from its centerline during rough conditions, yet provide enough resistance to dampen this effect.
However, the total buoyancy of the buoy must be carefully considered at this stage, as the chain cannot be too heavy such that it contributes to submersion of the buoy if it becomes fully drawn up from the seafloor. A method for slightly reducing the chain weight while simultaneously preventing it from becoming caught on objects on the seafloor is to install trawl floats at the terminus of the chain, at the location where the primary mooring line is connected. The buoyancy provided by these floats can help to maintain a segment of the chain in suspension as illustrated in Figure 4.
A secondary consideration in calculation of mooring line length is serviceability of the instruments deployed. For practicality, it may be desirable to be able to access sensors mounted along the mooring line without having to lift the entire anchor system from its placement. This additionally helps to ensure that the buoy remains stationed at precisely the same location both before and after service.
Depending on sensor depths, this may or may not be achievable, but it will be theoretically possible any time the sensor depth is less than the drift radius, provided that maintenance is carried out under low and/or calm water conditions. Heavy chain connected to the anchor can also contribute to facilitating this, since it normally rests on the seafloor and contributes to anchor weight but may be lifted up during maintenance (preferably with the assistance of a winch or crane on the service vessel).
The diagram in the previous section illustrates an example where placement of the two sensors is less than the drift radius when accounting for the bottom chain length, so it should be possible to access the sensors for maintenance without disturbing the anchor placement.
Mooring Hardware Materials
A wide range of hardware options are available, and these can largely be selected based on site conditions, but there are a few critical points which should be considered.
Sensors suspended below the buoy frame can optionally be mounted onto NexSens-issued stainless steel mooring lines. Sensors can be securely mounted using MC-600 mooring clamps specifically designed for use with these mooring lines.
Due to the weight of such wirelines, it is often preferable to use a neutral-buoyancy or even net positive buoyancy mooring rope with sufficient strength to perform well in the site conditions, for example Superdan® 8-strand or 12-strand ropes. Mooring lines with elastic properties may also help to reduce the total line length required and thereby reduce the drift radius as well.
If a positive buoyancy rope is used, this may result in some slack in the mooring line especially during calm conditions, thus forming a so-called S-shaped mooring as pictured in the diagram below. A potential issue with this is rope floating up and coming into contact with sensors, which can cause measurement interference, particularly on optical sensors. Rope floating all the way to near the surface can also present a risk of being snagged by passing boat/ship traffic. For those reasons, some weight should be added to limit the amount of flotation that can occur, similar to what is illustrated in the figure. However, it is important to keep in mind that this will count against the net buoyancy provided by the buoy.
Biofouling resulting in growth on mooring lines can also contribute additional weight during a deployment, so buoys and mooring lines should be periodically inspected and cleaned to ensure there are no issues. Any visual change to the way the buoy sits on the water surface during calm conditions (e.g. listing or sitting lower than normal) should immediately be inspected.
To connect mooring components together, various shackle types may be used. Here, it is important to consider the materials of construction. The internal frame of CB-Series buoys is constructed of Type 316 stainless steel. Thus, to avoid mixing metals, any shackles connected directly to the buoy should also be made of 316 stainless steel.
At the seafloor, galvanized steel shackles, bottom chain and anchors may be used, provided there is consistency of materials. To guard against corrosion in saltwater environments, the buoy frame should be equipped with zinc anodes (NexSens part number CB-ZA).
For protection of sensor data cables, it is recommended to secure the cable using steel-lined cable ties at many points along the sensor wireline (or equivalent mooring line). This is to ensure that there is plenty of slack in the data cable and that all loads are carried by the wireline/mooring line and NOT the data cable. Twisting in the wireline should be reduced as much as possible. This can, in some cases, be achieved by using a stainless steel swivel at the point where the wireline connects to the primarily buoy mooring line. A swivel should NOT be used directly at the connection to the buoy frame, as this will allow the buoy to rotate around the mooring line connection. An exception to this would be if no sensors are suspended below the depth of the buoy's internal frame.
Due to the size and total weight of medium-deep water moorings, it is strongly recommended to deploy using an appropriately-sized vessel equipped with a crane and winch for controlled lifting and release of the mooring system and buoy. The following describes the process for a typical deployment.
- Lay out the buoy and mooring hardware on the vessel's deck such that all connections can be made and the mooring line can be paid out without risk of tangling.
- Use the crane to lift the heavy anchor and carefully lower it over the side of the vessel at the deployment site. Use the winch to hold the mooring rope such that the release is controlled throughout.
- Tip: To pay out the anchor and bottom chain without having to run the chain through the winch, an off-load hook (e.g. from Henriksen or equivalent) is a handy helping device. Commonly used with lifeboats, these hooks have an automatic self-open function that causes the hook to

Communities far from the southern border are taking extra steps to integrate new Hispanic residents.
The Hispanic population is growing more rapidly than other segments of the U.S. population, according to U.S. Census Bureau data released in May, so a growing number of local governments are working to integrate Latinos into their communities. Many cities are establishing liaison offices, improving communication with, helping immigrants learn English, and creating programs and events that help all residents embrace cultural diversity.
Latinos are not integrating as well as Asians, blacks and non-Hispanic white immigrants, according to the Washington-based Migration Policy Institute's report "Immigrants in the United States: How Well Are They Integrating into Society?," which was published in May. The report says Hispanics' progress — while occurring — has been slower in the areas of English proficiency, income, education, homeownership in integrated neighborhoods, legal status, voter registration and intermarriage.
Lack of integration can lead to a general feeling of not belonging and, therefore, a lack of participation in the political process and community activities, according to the Washington-based' (NLC). "Municipal Innovations in Immigrant Integration" report. The points out that immigrants sometimes become victims of crimes and, if they are undocumented, often fail to report the crimes for fear of being deported. Also, because immigrants may not know their tenant and property rights, landlords and others in the industry can take advantage of them. They also might not receive community messages about mental and other health issues and how to be screened and treated for them.
Having a plan to help immigrants integrate into the community is key to overcoming the hurdles that the Hispanic community is facing, says Ricardo Gambetta, NLC's manager of Immigrant Integration Programs. To aid struggling cities, NLC is supporting the creation of New American Citizens' Academies in several cities to help new residents who are going through or who have recently completed the naturalization process learn about the local government. NLC also encourages local governments to work with state agencies, provide input to the federal government regarding a nationwide strategy on immigration, create mayoral advisory boards on immigration issues and ensure that any plan includes a strategy across all agencies.
Cities need to tailor their approaches to integrating Hispanic residents based on those residents' specific needs, Gambetta says. "Every city is different and unique," he says. "The issue is complex, and we focus on promoting city engagement. We believe cities are integral in the integration of immigrant communities."

The Community Relations Service is the Department's "peacemaker" for community conflicts and tensions arising from differences of race, color, and national origin. Created by the Civil Rights Act of 1964, CRS is the only Federal agency dedicated to assist State and local units of government, private and public organizations, and community groups with preventing and resolving racial and ethnic tensions, incidents, and civil disorders, and in restoring racial stability and harmony.
With passage of the Matthew Shepard and James Byrd, Jr. Hate Crimes Prevention Act, CRS also works with communities to employ strategies to prevent and respond to alleged violent hate crimes committed on the basis of actual or perceived race, color, national origin, gender, gender identity, sexual orientation, religion or disability. CRS facilitates the development of viable, mutual understandings and agreements as alternatives to coercion, violence, or litigation. It also assists communities in developing local mechanisms, conducting training, and other proactive measures to prevent racial/ethnic tension and violent hate crimes committed on the basis of actual or perceived race, color, national origin, gender, gender identity, sexual orientation, religion, or disability. CRS does not take sides among disputing parties and, in promoting the principles and ideals of non-discrimination, applies skills that allow parties to come to their own agreement. In performing this mission, CRS deploys highly skilled professional conciliators, who are able to assist people of diverse backgrounds.
For more than 45 years, CRS has been asked to provide its experienced mediators to help local communities resolve conflicts and disturbances relating to race, color, or national origin. Each year CRS' highly skilled conciliators bring hundreds of community-wide conflicts to peaceful closure across America and its territories.
CRS lends its services when requested or accepted by the parties. The Service uses impartial mediation practices and conflict resolution procedures to help local leaders resolve problems and restore stability. CRS has no law enforcement authority and does not impose solutions, investigate, prosecute, or assign blame and fault. All CRS mediators are required by law to conduct their activities in confidence, without publicity, and are prohibited from disclosing confidential information.
CRS conciliators work with State and local officials and community leaders to provide a wide variety of services to address racial issues and prevent violent hate crimes committed on the basis of race, color, national origin, gender, gender identity, sexual orientation, religion, or disability. CRS' services include:
- Contributing expertise and guidance on methods and policies that calm tension and conflicts associated with race, color, or national origin or with preventing and responding to violent hate crimes committed on the basis of actual or perceived race, color, national origin, gender, gender identity, sexual orientation, religion, or disability.
- Enhancing strategies of State and local governments and community groups to prevent and respond to civil disorders.
- Improving lines of communication between parties experiencing tension or conflict, including Federal, State, and local officials, community leaders and residents.
- Helping schools and universities effectively deal with incidents of tension or violence associated with race, color, or national origin or with preventing and responding to violent hate crimes committed on the basis of actual or perceived race, color, national origin, gender, gender identity, sexual orientation, religion, or disability.
CRS assists willing parties and explores opportunities to develop and implement local strategies that can help law enforcement, local officials, civil rights organizations, and interested community groups respond to alleged hate crimes and find ways to prevent future incidents.
State and local law enforcement officials and community leaders may contact CRS to request assistance in improving communication between law enforcement and community members in the aftermath of a hate crime. CRS may help facilitate dialogues between law enforcement and community members to increase mutual understanding about the investigative and prosecutorial process as well as the concerns of people in the community.
CRS improves community response mechanisms, by facilitating the development of community capacity to help prevent hate crimes with services and programs that include: conciliation, mediation, training, technical assistance, and other tension reduction techniques.
CRS may introduce the community to representatives of agencies that respond to hate crimes, including federal, state, and local law enforcement officials, local government resources as well as community organizations (advocacy organizations, and other service organizations).
CRS also responds to requests for assistance from law enforcement and community organizations for contingency planning and self-marshalling training before large protests or events to help keep events safe. We facilitate meetings between all parties involved, and serve as a neutral entity to ensure logistics are coordinated and that information is shared appropriately.

'checksum': # md5 hash of file, created by DS, do not set or modify
'my.organization.MyActivity.myProperty' # private property, prefixed with activity name to avoid name clashes
Due to bug #4662 only some known properties are retained! The list is at the bottom of datastore/ (fixed in Sugar 0.83)
And custom properties must have String values for now (bug #5134).
And since Sugar 0.83 all former String values are now stored and returned as Arrays of Bytes. You can still set them as Strings.
Keeping and Resuming
To create an item in the datastore, call create():
object_id = datastore.create(properties, filename, transfer_ownership)
The metadata properties are a dictionary (type "a{sv}") containing (at least) the entries mentioned above. If filename is not empty, the file will be moved or copied to the datastore, depending on the transfer_ownership flag. The activity should delete the file once the call completes (if transfer_ownership was false). Otherwise (if transfer_ownership was true) the datastore will remove the file. For this to work under rainbow you must place the file in the "instance" directory. The returned id will be a string like '4543af91-7be9-404e-b2f1-3e27cb15a15d'.
To update an item use update():
datastore.update(object_id, properties, filename, transfer_ownership)
Again, if a filename was given and transfer_ownership is false, the activity is responsible for deleting the file after the call returns.
To retrieve an object's properties and file:
properties = datastore.get_properties(object_id)
filename = datastore.get_filename(object_id)
The returned temp file should be deleted by the activity as soon as possible, latest when the activity quits.
The metadata properties need to be preserved and stored again when updating an entry. An activity should also track updates to the properties made in the Journal while editing the datastore object. For this it should subscribe to the Updated signal:
An efficient way to do this is registering a DBus match like path='/org/laptop/sugar/DataStore', member='Updated', interface='org.laptop.sugar.DataStore', type='signal', arg0='objectId' --Bert
Activities may query the datastore:
(results,count) = datastore.find(query)
It returns the results as array of properties and a count of matching items (the array may have fewer items if the query was limited). In addition to the usual metadata items, the properties will include the object id at key 'uid', the mountpoint of the item at key'mountpoint', and possibly a 'filename' if requested.
The query can be a:
string: fulltext search
the given string is searched in all text properties
dictionary: structured query
the key-value pairs in the dictionary specify the value (or array of values, or dictionary specifying range) for a specific property, e.g.:
'title' = 'First Project' (but see note below)
'mime_type' = ['image/png', 'image/jpeg']
'mtime' = {'start' = '2007-07-01T00:00:00', 'end' = '2007-08-01T00:00:00'}
also, there are a few specific keys to adjust the query:
'query': fulltext search term
'order_by': key (or array of keys) to order results by, to reverse order use '-key' (but see note below)
'limit', 'offset': return only limit results starting at offset
'mountpoints': array of mountpoint ids to search (or all if not specified)
'include_files': if true, generate files as if get_filename() had been called for each item. In results, a property 'filename' will be added.
NOTE: Since Sugar 0.84 only very few keys are supported ('uid', 'activity', 'activity_id','mime_type', and 'keep', see here). Other keys are ignored so you may get back more results than expected. Results are ordered by timestamp by default. Sort keys are limited, too (none in 0.84, in 0.86 'timestamp' and 'title', see here).
You can also retrieve an array of unique values for a field:
values = datastore.get_uniquevaluesfor(property, query)
Note that currently (2007-07-25) the query is ignored in this call, it looks for all values in all entries.
Progress Display
To add a progress bar to a Journal entry (like the Browse activity does while downloading files), create an entry with a "progress" property in the meta data. The value is the percentage done (0 to 100). The file cannot actually be stored incrementally in the datastore, it needs to be saved to a temp file first. But the entry metadata can be updated continuously to inform the user of progress while creating the temp file (by not giving a filename yet in the update() call). Once the temp file is complete, it can be checked-in as usual. The user can cancel by clicking the x icon next to the progress bar. This deletes the entry, so you need to watch for the datastore's "Deleted(id)" signal.
meta =... # regular metadata
meta["progress"] = 0
id = datastore.create(meta, "") # create with progress bar
while (done() < 100) {
 if (got_signal(datastore, "Deleted", id))
 return user_cancelled();
 meta['progress'] = done()
 datastore.update(id, meta, "") # update progress bar
datastore.update(id, meta, # check-in file, remove progress bar
Journal UI
The Journal activity provides a D-Bus service to allow activities to bring up an object chooser dialog, focus searches etc.:
Service name: org.laptop.Journal
Object path: /org/laptop/Journal
Interface: org.laptop.Journal
Choosing Objects
Call this method to bring up the Chooser dialog (which looks like a small journal overlayed on your activity):
chooser_id = org.laptop.Journal.ChooseObject(xid, what_filter)
The xid should be your activity's X window handle, or 0. The filter says what type of Journal entries is preselected in the drop-down menu (this parameter was added in Sugar 0.83). It's a string containing either a bundle id (e.g.,'my.organization.MyActivity'), or one of the generic data types ('Text', 'Image', 'Video', 'Audio', 'Link' definition), or an empty string for no filter. The call returns immediately with a string chooser_id. You need to watch these signals which get emitted when an item is chosen or the dialog is canceled:
ObjectChooserResponse(chooser_id, object_id)
The object_id received in an ObjectChooserResponse signal then can be used to open the corresponding datastore object.
Focusing Objects
The Journal activity allows an activitiy to "focus" an object, so the user can immediately open it (this is currently the only way to have one activity "launch" a different activity).
Switches to the Journal activity and shows the selected object.
This can be used to, e.g., open a URL (create a URL object in the journal then call this) or to view source code (store the source code as text file in the journal then call ShowObject() on it).
To focus on multiple objects: org.laptop.Journal.FocusSearch(query) Removed in Sugar 0.83
Mount Points
Devices are represented as mount points in the datastore. If no mountpoint is explicitly specified, the main datastore (Journal) is used.
 mounts = datastore.mounts()
Returns an array of mount point descriptors where each descriptor is a dictionary containing at least the following keys:
'id': the id used to refer explicitly to the mount point
'title': Human readable identifier for the mountpoint
'uri': The uri which triggered the mount
Mount points can be specified when creating an object (using a'mountpoint' key and id value in the properties), and when querying the datastore (by adding a'mountpoints' query option).
Large files to be stored on an external device should be placed at the uri of the mount point (see external media).
Activities are isolated from each other and from the "olpc" user. They do not have the same permissions as you would expect in a non-restricted Linux environment (see Bitfrost and Rainbow). In particular, they can not write in the /home/olpc directory!
Users and Groups
While Sugar runs as user "olpc", activities do not (the Terminal activity as a maintenance tool is an exception).
Instead, each activity instance is run with a unique user id. That is, a new anonymous user is created when the user clicks an activity icon, and the Rainbow demon runs the activity under that user.
All instance of the same activity get the same unique group id. That is, a new anonymous group is created when the activity is run for the first time,

To help you identify whether an away day is right for your team, we've put together a list of 8 signs that your team could benefit from a corporate away day.
1. Team members have trouble with communication
One of the first signs that your team needs a corporate away day is that they are either struggling to communicate, or communicating poorly.

Improve team communication with a corporate away day
Lack of communication often means that wires get crossed and things are frequently misunderstood. Or perhaps due to poor communication, people do not feel comfortable enough to share ideas and contribute to the team.
One way to assess whether the communication in your team needs to improve is to analyse the language used. One sure sign of poor communication is the frequent use of 'no,' or 'but.' If people become defensive about their ideas, they are more likely to shut down the ideas of others with a 'no' or a 'but', causing a breakdown in collaboration and perpetuating a negative environment.
Research shows that negative communication not only creates an uncomfortable office atmosphere, but also leads to lowered employee productivity, increased employee turnover and a less profitable company.
2. Your team struggles with negativity
Another sign that your team needs a corporate away day will come from a persistent negative atmosphere or negative use of language in the workplace.
Perhaps your team are acting selfishly, they are pessimistic, or they are letting negative events outside of the workplace effect their performance and attitude at work. Negativity is particularly damaging as it can be infectious in the workplace. If one employee has a poor attitude, it can quickly spread to the rest of the team.
Negativity in the workplace often leads to absenteeism, poor performance and low morale, all of which impacts on your company's ability to deliver excellent service.
3. There is a persistent lack of clarity
Lack of clarity about the direction of the team, business goals or overall purpose can all contribute to a dysfunctional team.
Do your team meetings frequently take 2 hours rather than 10 minutes? This is a clear sign of lack of clarity within the team. If your team enters a meeting without proper planning, or without clear direction, then meetings are likely to frequently overrun. Lack of clarity also means that team members work in silos. Lack of clarity on common goals can often result in individuals focusing on their own role and responsibilities, with little idea about the roles and importance of others.
All of this not only harms communication and productivity, but also effects employee buy-in. When employees have clarity about the goals, aims and plans of the company, and even better, when they are allowed to become a part of shaping these, they are more likely to engage with work in a long-term, meaningful way.
4. There are frequent frictions between team members
Another one of the signs that your team needs a corporate away day is that there is always 'workplace drama.'

Workplace drama is one of the clear signs that your team needs a corporate away day
American Society of Employers research into workplace drama shows that workplace drama can affect the company's bottom line. Employee turnover is likely to be high, productivity is likely to be low, and morale is often poor in a volatile, negative office environment.
Of course, you can never expect that all members of your team are going to get on with each other 100% of the time. However, if workplace frictions are a frequent occurrence in your office, you need to take action to resolve this issue.
5. Your team suffers from lack of accountability
Lack of accountability can be one of the clear signs that your team needs a corporate away day.
Lack of accountability can often mean that employees are unable or unwilling to admit to faults. This often makes it difficult to pinpoint why projects are delayed or completed incorrectly. But why does this mean that your team is dysfunctional?
Lack of accountability often comes from a negative team atmosphere in which employees are afraid of the consequences of admitting to a mistake. This can be a sign that your office does not have a structure in place for respectful, constructive criticism and there is a fear of a backlash occurring.
Lack of accountability often leads to delays or failures of projects, low morale, unclear priorities and diminished trust between team members.
6. Your team members aren't engaged
A lack of engagement or lack of motivation among team members can be one of the more difficult issues to notice, but once recognised is one of the most obvious signs that your team needs a corporate away day.
Employees may still be completing work on time and to a satisfactory standard. However, it is important to work out whether your team members are really engaged in the work they're doing, willing to go the extra mile, or whether they are simply completing the bare minimum.
This is detrimental to business as quite simply, disengagement costs you money. Engaged employees are more likely to work harder, complete work to a higher standard, keener to use their initiative and are more likely to remain long-term employees.
7. Team productivity is low
You should definitely consider a corporate away day if the productivity of your team is low or unsatisfactory.
Perhaps employees are struggling to hit their goals and targets, or you find that there is a lot of idle, unproductive time among your teams. Often it can be difficult to pinpoint the exact reason for this, as lack of productivity is usually a long-term, deep-rooted issue.

Lack of productivity and engagement means that your team will benefit from an away day
It goes without saying that low productivity affects the bottom line of the business, however it can also lead to low morale and high staff turnover.

Animal Mummies as Food for the Dead
Click on the images to enlarge.
Often, animals were mummified (essentially dehydrated) and placed in tombs to serve as food for the deceased. Fish, fowl, and beef were common "food mummies;" the beef was generally cut into steaks and roasts prior to being mummified. Sometimes these types of mummies were wrapped, but often they were not; it was common to store small fish mummies together in vessels.
"Food" mummies were not afforded the special ceremony or special adornments given to votive animal mummies. Compare the photographs of the small perch "food" mummy with the larger perch "votive" mummy. The votive perch was prepared with much more ceremony as it was likely intended as an offering to an ancient god; it was wrapped and included a decorative shroud/netting.

How old do chilies grow?
Depending on the chilli variety, the plant can grow to different ages:
Capsicum is the botanical name for chillies, peppers and chilli peppers. Chillies can live between 1.5 - 15 years, depending on the species. The wild species chilitepin grows perennially as a small bush. In the region of Texas, Arizona and Florida, this wild variety can survive 35 - 50 years without frost. This may make the presumed precursor of Capsicum annuum the oldest chilli plant in the world in two respects.
Annuum means annual, which is not literally true. Any chilli can be grown as an annual if it dies in winter due to frost. However, if Capsicum annuum chilli plants are protected from frost, they will usually still bear fruit the next year. Experience shows that this variety will easily live for 18 months. Two to three years are quite possible. In our experience, annual chilli varieties form many fruits in the first season. After the chillies have matured in the second season, the pepper plant dies.
Chinense means "from China" which is not correct. Capsicum chinense also originated in America. From the Amazon basin, it spread to all of South America. After the discovery of America, chilli seeds came to Europe and finally to China. In Asia, the chilli was cultivated on such a large scale that it was later assumed that it also originated here.
Capsicum chinense chilli plants grow relatively slowly. If you want to have a good harvest in the first year, you have to start early with the cultivation. Habaneros and Jolokia belong to the hot representatives of Capsicum chinense. Here you can expect a good harvest between 3 and 5 years.
Chillies from the baccatum plants can grow up to 4 metres tall. Normally around two metres. Their varieties often bear the name "Aji" and usually live between 4 and 6 years.
These plants grow compact and bushy. The one to four metre high bushes hang full of countless hot chillies. Some report that they have been overwintering Tabasco plants for eight years. After about five years, the plant would have lost its productivity. Nevertheless, it would be too bad to let the plant die and therefore it would get its reprieve.
Pubescens plants grow very old for chillies. The hairy plant spreads to up to eight metres. It is considered difficult to grow. However, the climate in Germany is quite suitable. Rocotos grow in the Andes and like high day/night temperature fluctuations. It can also tolerate light frost.
Most Capsicum pubescens plants grow to about 2 metres tall and grow similarly to vines. It forms woody branches already in the first season. Rocotos that are 15 years old have been reported.
|Capsicum annuum||1,5 – 3 Years|
|Capsicum baccatum||4 – 6 Years|
|Capsicum chinense||3 – 5 Years|
|Capsicum frutescens||3 – 8 Years|
|Capsicum pubescens||5 – 10 Years|

Charlie Sneddon OBE, a former Provost of Bo'ness, has died, aged 83.
Charles Sneddon was devoted to furthering the fortunes of Bo'ness, and served as its provost from 1964-75 and never ceased supporting the town both commercially and as a place to visit. From 1959, he was a councillor and then served as vice-convener of the Central Region from 1975 and convener from 1986-90. He brought to all these posts a keen sense of integrity and a commitment to helping others that remained paramount throughout his life.
In 1984, Mr Sneddon was awarded the OBE. Many local friends joked that it stood for Outstanding Bo'ness Efforts. It was a reflection on his standing in the community and the admiration and respect with which he was held.
Charles was one of six brothers and a sister and attended Bo'ness Academy. He first worked in shipping but progressed to jobs with Fisons and then BP Petrochemical at Grangemouth.
His work on the reclamation of land on the south side of the Forth – the site of the old Bo'ness port – was hugely important and the development created a much-improved environment.
In 1964, Mr Sneddon became the youngest provost in Scotland, and fought to improve the housing in Bo'ness. He was devoted to his family, the Labour Party and Scotland.
Sneddon's son, also named Charles, remembers his father as "always preserving Bo'ness uppermost in his heart. He wanted to improve the living conditions and bring more work to the area. Dad was a modest man and seldom sang his own praises. He was a good and generous man."
One of his great annual joys was the Bo'ness Children's Fair Festival.
As provost, Sneddon was always keen to praise local endeavour. When he opened the Deanburn Primary School in 1971, he praised the headmaster, James Vallance, saying: "In these few short months he has worked wonders."
In 2007, he unveiled a memorial to mining and the miners of the area. He had campaigned for such a memorial for many years and, along with the Bo'ness Pipe Band and the Kinneil and Unisor Brass Band, unveiled a mine-winding machine in their honour.
In 1996, Mr Sneddon was a awarded the coveted McLaren Trophy which is given annually by the community council to a person or group for outstanding services to Bo'ness.
Sneddon was an avid supporter of Bo'ness FC and assisted in many ways at Strathcarron Hospice. He was a keen golfer, often playing at the West Lothian course with his brothers. He was instrumental in preserving the future of the club by encouraging members to buy much of the land.
Tam Dalyell spoke warmly of his long friendship with Sneddon. "Charlie was one of my best friends in politics – from the time we were both involved in the Labour Party in 1956. He never said, nor did, anything cheap and was primarily concerned with giving practical help to members of his community. Charlie was a towering figure in local government."

How do I know if a small fish is a minnow?
Q: How do I know if a small fish is a minnow?
A: Not all small fishes are minnows; many are the young of other fish. A number of characteristics serve to separate small fish from true minnows. All minnows have naked heads except during breeding season when mature male develop many hornlike bumps, called tubercles. Some minnows also develop bright colors during breeding season, as suggested by such names as redside dace, redbelly dace, rosyface shiner, red shiner and redfin shiner. A single dorsal fin with fewer than 10 soft rays is characteristic of all native minnows. In carps and goldfish, the dorsal fin has a hard ray and more than 10 soft rays. Minnows lack teeth in their jaws, but have specialized teeth in their throat (pharynx) region. These pharyngeal teeth are useful in identifying the various minnow species.
Minnesota is currently home to 47 different minnow species, according to the Bell Museum of Natural History.

Recognition of the importance of soil compaction is increasing, but instrument cost, measurement repeatability and data interpretation limit its measurement on agricultural and rangelands. The dynamic penetrometer described here follows ASAE standards but replaces the proving ring with a strike plate, a shaft extension and a sliding hammer. The penetrometer cone eis pushed into the soil by successive hammer blows. Penetration resistance is calculated as the work by the soil needed to stop cone movement divided by the penetration distance. The work by the soil is defined as the kinetic energy of the hammer when it impacts the strike plate. Construction cost is approximately US$100. The standard drop height and hammer mass ensure measurements are consistent between operators.

optoAlso opti-.
[Greek optos, seen.]
Optometry is the occupation of measuring eyesight, prescribing corrective lenses, and detecting eye disease. The form appears in a few terms relating to the use of light in electronics, especially optoelectronics (or optronics), the branch of technology concerned with the inter-conversion of electronics and light; and optocoupler, a device containing light-emitting and light-sensitive components, used to couple isolated circuits.
Words in opticome from Latin opticus or optica, which derive from the same Greek source. Examples are optic and optical, of or relating to the eye or vision; optics, the scientific study of sight and the behaviour of light; and optician, a person qualified to prescribe and dispense glasses and contact lenses, and to detect eye diseases.


text: We report on the nanopatteming of double-bond-terminated silane (5-hexenyltrichlorosilane, HTCS) molecules on titania (TiO2) using conductive atomic force microscopy (AFM). The influences of tip electrostatic potential and scanning velocity, relative humidity and of the repeated application of voltage on the topographic height, width, and hydrophilic and hydrophobic contrast of the resultant patterns were investigated. Tip voltage and tip velocity (v) were applied between -10 V <= V-tip <= +10 V and 100 nm/s <= v <= 2 mu m/s during the lithography step(s), respectively. Average height and Lateral Force Mode (LFM) images of patterns were obtained with different values of(-10 V <= V-tip <= -7 V) and v (100 nm/s <= v <= 2 mu m/s). The average height of the patterns is seen to decrease for increasing v and decreasing V-tip in both a single or repeated lithography step. No patterns were observed following a single or repeated lithography step for -5 V <= V-tip <= +10 V. This conductive lithography technique results in nanoscale physiochemical manipulations of the HTCS molecules that are manifested as controllable step heights ranging from similar to 1-15 nm possessing different chemistries on the patterned and unpatterned areas. The use of conductive-AFM nanolithography for altering and manipulating double-bond-terminated molecules on TiO2 surfaces suggests a range of applications, including selective immobilization and assembly of functionalized inorganic nanoparticles and biomolecules.

Six large storytelling organisations in the Netherlands are cooperating to prioritise the art of storytelling within society.
Culemborg, 26 jan'19 – During the National Storytelling Event 2019 the six largest storytelling organisations within the Netherland have come together during to found the Federation of Dutch Storytelling Organisations. Within the next five years the Federations aims to increase the role of storytelling within the educational system, among the performing arts and with the national heritage concerns and relevant social organisations.
Similar to the Federation for European Storytelling (FEST), the Dutch Federation wants to assume a leading role in the attempt the emancipation of storytelling, but on a more local level. "Today, more than ever, we live in a world that is always developing and globalising. In these constantly changing times, the need for stories and storytelling arises. Storytelling takes a more prominent role within society. The term "storytelling" is no longer only used within its own community, but is utilised in advertising, marketing, by business managements and by cultural organisations. The federation offers all interested and relevant institutions the opportunity to discuss the possibilities of incorporating storytelling further within society, and thus create a more prominent place for storytelling in everyday life."
We define storytelling as the oral transmission of stories. Since the beginning of time, storytelling and stories have given people the means to understand and come to peace with the world surrounding them. Stories can explain the workings of the world, create understanding between different cultures, pass on knowledge, experience and legacies throughout time and can give hope and direction to those wo feel lost.
Long term aims:
The Federation has several long term aims, such as to get storytelling recognised as cultural heritage and to have stories become part of the National heritage collection. Another goal is to make storytelling an obligatory part of the curriculum of high, middle and primary schools in the Netherlands. Storytelling must become a mandatory part of the education of Primary teachers. They also strongly believe that storytelling should be recognised as in individual (theatre) art discipline. As such it should be a part of several important theatre programmes and festivals and be considered by performing art funds.
The founding fathers:
The founding organisations are all major contributors within their various aspects of the storytelling field. All of them have different areas of expertise in which the operate such as education, preforming art, advocates, applied storytelling arts, and cultural education. In the future the Federation hopes to welcome more members to help peruse their goals.
The Founding organisations are:
- De Vertelacademie NL/BE, fort he education of storytellers
- Stichting Vertellen, an advocate for storytellers
- Storytelling Centre, organization for social and culturean storytelling projects and organizer of the Amsterdam Storytelling Festival
- Theaterbureau Het Verteltheater, storytelling agency of educational performances and theater.
- Productiehuis De Verhalenboot, organiser of Storytelling Festival Zwolle Unlimited, the Wereldberoemde Verhalenfestival and the Vertellersgilde.
- Mezrab, initiator of the Mezrab Storytelling School and the Mezrab House of Stories.
