 18.2.3 Immediates vs Non-immediates
 -----------------------------------

 Guile classifies Scheme objects into two kinds: those that fit entirely
 within an 'SCM', and those that require heap storage.

 The former class are called "immediates". The class of immediates
 includes small integers, characters, boolean values, the empty list, the
 mysterious end-of-file object, and some others.

 The remaining types are called, not surprisingly, "non-immediates".
 They include pairs, procedures, strings, vectors, and all other data
 types in Guile.

 -- Macro: int SCM_IMP (SCM X)
 Return non-zero iff X is an immediate object.

 -- Macro: int SCM_NIMP (SCM X)
 Return non-zero iff X is a non-immediate object. This is the
 exact complement of 'SCM_IMP', above.

 Note that for versions of Guile prior to 1.4 it was necessary to use
 the 'SCM_NIMP' macro before calling a finer-grained predicate to
 determine X's type, such as 'SCM_CONSP' or 'SCM_VECTORP'. This is no
 longer required: the definitions of all Guile type predicates now
 include a call to 'SCM_NIMP' where necessary.

First-generation student goes to college
CFCA sponsored youth Alfred.
CFCA sponsored youth Alfred.
Alfred is a sponsored youth from Bhagalpur, India, who is the first person from his village to attend college. Alfred is also a CFCA scholarship student, which helps cover other costs related to his education. Alfred sat down with Sreekanth, our communications liaison in India, to tell us about the academic and social challenges heís experienced as a college freshman.
Are you a first-generation college student? If so, how were you given this opportunity to attend college? Why did you decide to attend?
My father studied up to the ninth grade. He understands the value of education and encouraged me to study. Even though my college is very far away, he tried every opportunity to pay the fees and enroll me in school.
I am the first person to attend college from my village.
The hotel management and catering technology degree is a three-year diploma, and it is very expensive.
Though it is expensive, I preferred it because of CFCA's sponsorship and scholarship support. I paid part of my college fees with CFCA's help through sponsorship support and my CFCA scholarship. I was able to take out a bank loan for the remaining costs.
What did your parents think about your attending college? Did their attitudes change over time?
When I told them about going away to school and the about the college fees, my father told me that we would try to find the remaining costs from a different source.
Alfred with his family.
Alfred with his family.
We were able to use a portion of the CFCA sponsorship funds and the scholarship fund. The remaining costs were covered by a bank loan.
What are some of the challenges you've faced in attending college?
The major challenge is the language barrier. In college, teachers conduct classes in English. I had not studied the English medium, and it became difficult to understand.
I can manage writing English, but speaking is difficult for me.
I am practicing more, and soon I will speak fluently.
In the beginning, I felt that I was the poorest student in school. The other students arrive on bikes or in cars, and they are from very large towns. Many are not even familiar with my village.
I am happy that I can study among them.
How long does it take you to travel from home to college?
I am pursuing a degree in hotel management and catering technology, and the university is more than 248 miles (400 kilometers) from my home. It requires 12 hours of traveling.(Alfred stays near his school while classes are in session, and travels back home around the holidays, usually four times a year. For the final leg of his trip home, he walks eight miles from the main road to his home as there is no public transportation going to his village.)
What are some of the accomplishments you're most proud of in attending college?
I am proud to be the first person to go to college from my area.
CFCA sponsored youth
Alfred makes the long trip to the university and back.
Do you have to pay for lodging away from home in order to attend college? If so, who pays for it? How much does it cost?
At my school, hostel [boarding house] fees are expensive, and two friends and I decided to rent a room.
My father sends me money every month for rent and food expenses.
What are some other costs incurred by your college education?
Other expenses include uniforms, purchasing books, pots and pans, and groceries.
What are your plans for the future? What do you hope to do with your college education?
After I complete my studies, we will have campus selections (job fair). I participate in the campus selections and try for the best organization to join the job. I am ready to go any place to work. I am passionate to see the places..
After getting the job, my first target is to repay the education loan. I also have the responsibility of my family. I am also interested to serve the poor people.
If you could give a message to your sponsor or the donor for your scholarship, what would you say?
All my education expenses (up to intermediate) are paid for with the help of sponsorship support.
Whatever I achieved now is because of CFCA and my sponsor's help. I have been receiving support from second grade and beyond.
I am very much thankful to my sponsor and CFCA.

Experts from Tamil Nadu Agricultural University (TNAU) and Forest College and Research Institute (FC&RI) has undertaken a project to identify native grasses & trees in order to improve elephant habitats and standardise mass multiplication techniques.
Forest Department has set up eight-member group after they realised that areas occupied by native grasses and fodder trees in wild have been degraded.
- Team submitted an interim report recently in which they have identified 29 native grass species and 14 fodder tree species that are palatable for elephants and other herbivores.
- Team also started a nursery for growing these species in FC&RI campus.
- Leaves and plant parts of 29 native fodder grass species and 14 fodder tree species have been dried in the shade.
- They have also been powdered for characterising nutritional and anti-nutritional values.
- Scientists have undertaken the project with the objective of improving quality of elephant habitats by restoring them with native grasses and fodder trees.
About the project
- An interim report has been presented by the team. In the next phase, they will assess nutritive value of trees & plants and standardise mass multiplication technology to plant in lower slopes of Nilgiris and Coimbatore Forest Division.
- They have already assessed the fodder quality of same.
- Quality has degraded because of spread of invasive species such as lantana camara.
- These mountains are found in western Tamil Nadu and called as Western Ghats. 24 peaks of Nilgiri Mountains are above 2,000 metres in height.
- Highest peak is Doddabetta with height of 2,637 metres.
- Word Nilgiri has been derived from Tamil Word Neelam meaning blue and giri meaning mountain.
- Nilgiri Hills are separated from Karnataka Plateau by Moyar River.


Glass Substrate Effect on Raman Microscopy
Substrates for Raman Microscopy
Key Points
 - In Raman microscopy, the sample substrate can contribute to the Raman spectrum and hide valuable sample information.
 - Different substrate materials have unique optical properties and affect the Raman spectra in distinct ways.
 - This technical note investigates the effect of glass, quartz, calcium fluoride and stainless steel as a substrate, to help you understand their effects and maximise Raman data quality.
Introduction
In Raman microscopy, there are a multitude of parameters that need to be considered to acquire high-quality data. One of these, often overlooked, is the substrate on which the sample is supported, Figure 1. Various substrate materials are available, and each can influence the measured Raman spectrum differently. It is essential to understand the Raman properties of the substrate when designing an experiment to ensure that its spectral output does not obscure information about the sample of interest.1 This Technical Note will discuss the properties of four different substrates (glass, quartz, calcium fluoride and stainless steel) commonly used for Raman microscopy.
The substrate in Raman microscopy.
Figure 1. The substrate in Raman microscopy.
Raman Substrate One: Glass
The most common and cost-effective substrate for microscopy is glass, which can be purchased relatively cheaply in large quantities. Being transparent, glass microscope slides can be used for both reflected and transmitted illumination widefield microscopy. However, a significant drawback of using glass for Raman microscopy is background photoluminescence (PL), which can obscure valuable spectral information when standard laser wavelengths are used.2 Figure 2 shows the contributions of glass in spectra acquired using three different lasers, spanning the visible and near-infrared (NIR) regions of the electromagnetic (EM) spectrum.
Raman analysis of glass substrate using 532 nm, 638 nm, and 785 nm lasers.
Figure 2. Raman analysis of glass using 532 nm, 638 nm, and 785 nm lasers.
When analysed with a 785 nm laser (red curve), the glass exhibits a strong PL band that peaks ca. 1400 cm-1. This can be observed when the overlying sample is transparent or when the sample is protected with a glass coverslip. At 638 nm (green curve), the glass spectrum shows a combination of Raman signatures and the rise of a PL band. There is no PL at 532 nm (blue curve), but the glass Raman spectrum is still relatively complex, and it contains multiple broad bands in the same spectral window as many potential functional groups of interest. These unwanted effects can be avoided by covering the glass with aluminium foil; however, this is unsuitable when low working distance objectives are used because it is difficult to secure it with the required level of precision. The best approach is to use an alternative material to glass.
Raman Substrate Two: Quartz
Fused quartz is an alternative transparent substrate that can be used for Raman microscopy. The spectral output of quartz is less variable than glass when probed with different laser wavelengths. Figure 3 shows that quartz does not exhibit PL, a significant advantage over glass. The larger spectral plot is on the same scale as the above glass spectra, and the inset plot shows the vibrational signatures of the quartz in greater detail. The Raman spectrum is still complex compared to other available substrates, but the most prominent band is in a low wavenumber region that is less likely to overlap with vibrational modes of interest. Quartz is the substrate of choice in high-temperature Raman applications because it is extremely heat-resistant.

Figure 3. Raman analysis of fused quartz using 532 nm, 638 nm, and 785 nm lasers.
Raman Substrate Three: Calcium Fluoride
Calcium fluoride (CaF2) is another transparent material often considered the "gold standard" of Raman microscopy substrates. CaF2 has optical properties that are more favourable than glass and quartz for most Raman microscopy applications. To show this, the spectra of a CaF2 disk obtained with different wavelengths are plotted in Figure 4. CaF2 exhibits no PL, similar to quartz. The advantage of CaF2 is that it only has one narrow Raman band, ca. 330 cm-1, a frequency range in which most functional groups will not vibrate. This band is less likely to obscure sample features than the more complex Raman spectra of glass and quartz.
Raman analysis of calcium fluoride substrate using 532 nm, 638 nm, and 785 nm lasers.
Figure 4. Raman analysis of calcium fluoride using 532 nm, 638 nm, and 785 nm lasers.
Raman Substrate Four: Stainless Steel
Stainless steel slides are a non-transparent alternative to the previously discussed substrates with minimal background and no Raman spectral signatures. As shown in Figure 5, stainless steel shows less Raman signal than any of the aforementioned materials and negligible background emissions, making it an excellent substrate for Raman microscopy applications.
Raman analysis of stainless steel substrate using 532 nm, 638 nm, and 785 nm lasers
Figure 5. Raman analysis of stainless steel using 532 nm, 638 nm, and 785 nm lasers.
Stainless steel is not transparent to white light, and sample viewing is therefore limited to reflected illumination microscopy. Stainless steel can enhance the Raman intensity over alternative transparent materials because the reflectivity of the metal surface allows for double-pass of the laser beam through the sample.3 To demonstrate this, individual 3 μm polystyrene beads were analysed on glass and stainless steel, Figure 6. With the same laser and scatter path conditions, there is a significant improvement in the Raman intensity detected when the bead is on the steel substrate (blue) versus the glass (green).

Conclusion
In this Technical Note, we have discussed the effects of various sample substrates, such as glass, used for Raman microscopy, summarised in Table 1. It should be noted that quartz, calcium fluoride, and stainless steel are more expensive than glass, but they can also all be washed, sterilised, and reused. By understanding the properties of different substrates, it is easy to select the correct one and ensure that the spectral output of an experiment is exclusively from the sample of interest.
Table 1. Summary of the sample substrate materials discussed above.
Material PL Raman Microscopy Modes
Glass Yes Multiple broad peaks Reflected and transmitted illumination
Quartz No Broad peaks in low wavenumber region Reflected and transmitted illumination, high-temperature cells
Calcium fluoride No One narrow peak in low wavenumber region Reflected and transmitted illumination
Stainless steel No No Reflected illumination only, intensity enhancement due to laser double-pass

The fruits of the Arbutus already look very similar to the strawberries from the bed. We will introduce you to the best varieties from American and show you how to plant and care for Arbutus in the garden.
Well, are those strawberries on that tree? Even though the fruits of the Arbutus resemble red berries, the plant is not related to them. We'll tell you what this strange tree is all about.
Arbutus: origin and characteristics
The Arbutus, also known as a country berry, Hagapfel, or sea cherry, originally comes from regions like the Mediterranean, the Canary Islands, or North America. The plant has been fascinating people for a long time, as the mention in poems by Virgil and Ovid shows. In Central European gardens, however, this plant is now a real insider tip.
The Arbutus is characterized by quite slow growth, with a maximum height of about 5 to 40 meters in the open air – depending on the species. The leaves of the evergreen tree or shrub are reminiscent of those of the laurel tree.
From an age of about five years, the Arbutus is expected to bear fruit. Depending on the species, the plant blooms in winter or spring and shows its white to pink, panicle-forming bell flowers, typical of the heather family (Ericaceae), to which the tree belongs.
In spring, the red-orange strawberry-shaped berries that give the tree its name are formed, which can be harvested the following autumn. This makes the Arbutus an ideal eye-catcher in small and large gardens.
The Best Arbutus Varieties
The eleven different species of the Arbutus are divided into the old world and new world varieties according to their origin. Within the Old World species, the Arbutus unedo (Western Strawberry Tree), the Arbutus andrachne (Eastern Strawberry Tree), and the Canary Strawberry Tree (Arbutus canariensis) are the most important.
The American Strawberry Tree (Arbutus menziesii) is the best-known representative of the New World species. The Arbutus species differ optically mainly by their color and the shape of the flowers as well as the different growth height and winter hardiness.
The western strawberry tree is especially widespread in the western Mediterranean area but is also found sporadically on the Atlantic coast as far as Ireland. While most fruit trees bloom in spring, the Arbutus is an autumn bloomer and thus a real eye-catcher in the autumnal garden.
Between October and December, the plant shows white to pink, panicle-forming bell blossoms. The tree is dependent on cross-pollination. To enable the blossoms to be fertilized, you must therefore either have an Arbutus in a neighboring garden or plant two of these unusual trees in your garden.
The two to three-centimeter large fruits ripen in the following year and can be harvested in autumn during the next flowering. The western strawberry tree reaches a growth height of three to five meters. Relatively little breeding work has been done on the varieties of the plant, which is why a few special specimens are waiting for us here:
- Arbutus unedo 'Integerrima': The special feature of this variety is a particularly shrubby growth with brilliant white flowers in late autumn.
- Arbutus unedo 'Rubra': This variety offers a special color play with pink to light purple flowers in autumn.
- Arbutus unedo 'Compacta': This variety is ideal for those who want a small tree as a pot plant. It is characterized by a particularly small growth with a maximum height of one to two meters.
The Canary Strawberry Tree is originally only found in the Canary Islands, where it reaches a height of up to 15 meters. The fragrant and, unlike the Western strawberry trees, self-pollinating flowers appear in February in a white to a reddish shade. The fruits are ripe from late autumn to winter and are two to three centimeters large.
In the eastern Mediterranean region, such as in Greece or southern Albania, the Eastern Strawberry Tree is native to the region. The tree reaches a maximum height of twelve meters and the mostly white blossoms appear from February onwards. In autumn the orange-red fruits, which are about one centimeter in size, can be eaten.
The natural range of the American strawberry tree stretches along the Pacific coast of North America. Due to the strong temperature fluctuations in this region, the plant can easily cope with temperatures between -20 °C and +45 °C.
With a height of up to 40 meters and a trunk diameter of up to 150 centimeters, the New World American Strawberry Tree is the largest representative of the Arbutus. In contrast to the Old World plant, the plant blooms between April and May and forms spike-shaped inflorescences over twelve centimeters in size with small hermaphroditic white flowers. The fruits are one centimeter in diameter but smaller than the fruits.
Planting the Arbutus: location, timing, and procedure
We recommend planting your The Arbutus in spring or autumn. Summer is less suitable because the tree is sensitive to drought after planting. Unfortunately, The Arbutus is not suitable for indoor plants but needs the sun in your garden or on your balcony. Varieties such as Arbutus unedo 'Compacta' can also be grown outside in a planter. To avoid waterlogging, it is advisable not to use a coaster when cultivating in a pot.
The right location for Arbutus
Most Arbutus is best kept outdoors. Since the tree is very drought-tolerant, it feels especially comfortable in a dry and sunny corner of your garden. In winter, the American Strawberry Tree tolerates temperatures of -15 to -20 °C, all other species absolutely need winter protection and can only be planted in sheltered locations. Young Arbutus should first be cultivated in pots and left to winter without frost until the tree is sufficiently hardy at the age of five years and can be planted out.
How to plant an Arbutus
To plant your Arbutus, dig a hole one and a half times the size of the bale. Especially for trees over one and a half meters high, we recommend a wooden post as support. The tree can be fixed to the wooden post with a tree tie made of coconut rope.
However, the post and tree must not lie against each other, otherwise, the bark will be damaged by chafing. After planting, water the tree abundantly, preferably with the help of a watering rim. Especially during the next three weeks, you should now ensure a good water supply.
The tree is best watered with collected rainwater. This is good for the environment and contains less lime compared to tap water, which is good for the Arbutus.
Cutting the Arbutus
In young Arbutus, the shoot tips can be shortened somewhat in spring to promote denser growth. Sharp garden shears should be used to avoid crushing the wood. A smooth cut surface provides less surface for fungi to attack and helps to keep the tree healthy. Older trees develop best without interfering with their growth. Heavy pruning into old wood should be avoided if possible. Old wood should be removed from the crown and the branch cut back to green, i.e. still living tissue.
Both vegetative propagations via cuttings and a generative propagation of the Arbutus via the seeds in the fruits is possible. Propagation via seeds is a little more complex. The seeds swell for a few hours in water and are then stored in the refrigerator for two months, where they begin to germinate. Then the germinated seeds can be planted.
Cuttings of the Arbutus can be cut in autumn from woody but not too old shoots. The leaves of the cuttings, which are about ten centimeters long, are removed except for the top two and placed in soil. The cuttings are then covered with a transparent cover and placed in a light place at room temperature. New Arbutus then grows from the cuttings.
Are the fruits of the Arbutus poisonous or edible?
The fruits, which look like strawberries, can be harvested in autumn. The fruits of the Arbutus are edible, have a sweet-sour to sweet taste, and a slightly floury consistency.

To understand the effect of irradiation on SiCp
/Al composites for aerospace electronic components packing substrates, 3 MeV Fe11+
beam was used to carry out irradiation experiments under different ion fluence. After irradiation, X-ray diffraction (XRD) and nano-indentation were used to characterize and analyze the materials. XRD analysis indicated that the stress of irradiated layer changed after Fe11+
ions' incidence. Combined with the corresponding theoretical model, the dislocation density of aluminum matrix was calculated. It was found that the dislocation density of aluminum matrix increased, and the SiC particles were amorphized after irradiation. The measurement of nano-indentation revealed that the irradiation hardening of the material increased with the increase of ion fluence. It can be deduced that the irradiation hardening may be due to the stress changes in aluminum alloy matrix leading to the generation of local high-density dislocation regions, which impedes the subsequent dislocation movements, and ultimately increases the hardness of the material.


3 Basic Folkstyle Wrestling Moves
folkstyle wrestling moves in school
folkstyle wrestling moves in school
What are folkstyle wrestling moves? Folkstyle wrestling moves are also known as collegiate style wretling. They are any wrestling move that is legal or that is not illegal rather within the rules of folkstyle wrestling or collegiate wrestling. Many moves from Greco Roman and Freestyle wrestling are legal and carry over into folkstyle wrestling.
On my blog I recently posted some videos that demonstrate different folkstyle wrestling moves and drills. If you are interested in learning more wrestling skills then I suggest that you go to my blog and watch the videos. However, since this is an article and thus does not use video I will attempt to describe or explain what these moves are, how they are done and when you would use them.
The Granby Roll.
The Granby roll is a classic example of a folkstyle wrestling move. This skill is ONLY used in folkstyle wrestling and not in freestyle or Greco Roman Wrestling. This is a move that the wrestler will do from the bottom position.
You execute the Granby Roll by creating enough space between you and the top wrestler to move your hips out so that you are now at a T to your opponent. You are perpendicular to him rather. Then you want to catch his wrist and roll towards his head. As you roll you through your elbow in between his legs and catch the leg closest to you. When you come through you should, if done correctly, have your opponent on his back. You should be holding him there by locking his arm and leg around your body. Video explains this skill far better than I can with words, but I hope this helps.
Dive and Roll Single Leg Defence.
This move is not a high percentage move but from time to time, when a kid is really athletic or is a lot better than his opponent, this move works. This is a last resort way of getting out when your opponent has shot in and picked up your leg into the air. You are now hopping on one foot hoping not to get taken down. So, in desperation you turn away from the other wrestler, dive and roll. As you roll your leg kicks free. You then turn and face your opponent. Again, this is hard to explain if you have never seen the move. There is video of the move on my blog.
Head Lock.
The head lock is one of the most effective and most ineffective moves there is. It is a great way to score 5 points when you are losing or to get a much needed pin. It is important to do correctly and to know when to hit it otherwise a wrestler can get in trouble. You start by doing what is called a back step. It is a step you take to pop your hips through underneath your opponent so that you can then through him over the lower part of your back and onto his back. A great drill to practice this move is to have one wrestler pop his hips through and throw tehn hold the other person up. Then the other person pops his hips through and throws. You repeat this over and over.

Using Spring Connectors in SOLIDWORKS Simulation to Reduce Complexity in Your Analysis
By Paolo Olmos
I recently worked on a customer project which involved answering the question, "How can I represent complex sub-assemblies or components that are part of a larger assembly using SOLIDWORKS Simulation?" The customer wanted to include ball screws and linear rails. These sub-assemblies include bearings, threads, and complex mounting geometry that would require a significant amount of time and effort to setup - and a significant amount of time to solve. Additionally, if I were to miss an element in the setup, the analysis could fail or the results may be invalid. One way to simplify an analysis that involves complex sub-assemblies or components is to replace them with spring connectors. Replacing components with spring connectors allows you to:
 - Reduce the number of components that need to be meshed, improving solve time
 - Simplify the analysis setup, reducing the overall time necessary to execute the analysis
While maintaining the inherent stiffness of the components you remove by replacing them with an equivalent spring stiffness. As an example, let's take an assembly made of 2 plates with a spring in the middle. Including the spring in a linear static analysis with a 100 lbf load applied, the results show a displacement of 0.282 inches. To use a spring connector in this situation, the spring component is suppressed and replaced with a virtual spring that uses the stiffness data you have for the modeled spring. As you can see in the screenshots below, we can get the same displacements as the analysis that included the modeled spring.
Spring Connector
Right: Results With Spring, Left: Results With Spring Connector.
Comparing the setup and solve time between the two studies:
 - The setup time was short for both studies, but imagine if the spring was a more complex sub-assembly or component. It would require time to define contacts, material, and fixtures for all the elements in the sub-assembly or component. The setup time could be substantially longer.
 - The solve time for the actual spring took 6 seconds to solve versus 2 seconds for the spring connector analysis.
A couple of other things to consider when using spring connectors:
 - Make sure that the face selected for one body shares a common projected area on the face selected for the other body. If you don't, SOLIDWORKS Simulation cannot create the spring and will display an error when you try to run the analysis. In the example above, the faces selected had the same area and were directly overlapping when looking at the top view.
 - You can create split lines to separate the faces of each body in order to create a common projected area between them. In the example above, this technique would have been required if the spring was significantly smaller than the plates.
As you can see in this brief overview, spring connectors can help you obtain accurate results, while saving you time to setup and solve your analysis. Keep a look-out at this space for a follow-up blog article that covers using spring connectors to represent the ball screw and linear rail assemblies mentioned earlier, or watch my webinar: SOLIDWORKS Simulation - Representing Ball Screws and Linear Rails in Your Analysis.

i have the following snippet of javascript:
liChilds[x].onclick = function(){
toggleSubMenu(sub_menu_id, false);
return false;
That code happens within a loop, and sub_menu_id has a different value through each iteration of the loop. For example, if it loops 4 times, then there will be 4 onclick functions and sub_menu_id would change for each one. This should happen in theory, but instead, whichever item you click on, sub_menu_id takes the value of its last value in the loop. (4 in this example)
My question is, how do I make the function toggleSubMenu take the value of sub_menu_id at the time the on click function is created (i.e while looping) rather than taking the value of sub_menu_id when it is actually clicked.

The Nipponese Quince Essay, Research Paper
A.P. English The Nipponese Quince In The Nipponese Quince written by John Galsworthy, the actions of Mr. Nilson, a well-known and affluent man of affairs, consist the secret plan. The narrative basically describes Mr. Nilson s amble through Square Gardens, which leads to a realisation that he lacks spontaneousness, which in bend has prevented him from appreciating nature, so when he does see the beauty in nature, he gets fascinated by it. Developments in the secret plan are Mr. Nilson s feeling of emptiness, his infatuation with the Nipponese Quince, and the brush with Mr. Tandram.Mr. Nilson s complaint ab initio starts out as benign and described as a curious sweetish esthesis in the dorsum of his pharynx, and a feeling of emptiness merely under his 5th rib. However, this esthesis was intense plenty to hold Mr. Nilson deviate from his day-to-day modus operandi. This feeling of emptiness additions and shortly is more mistily described as a fagot feeling and a swoon hurting merely above his bosom. Mr. Nilson tries to explicate what is doing this, but ends up with nil. When Mr. Nilson says, and here I am the lone individual in the Square who has the-to come out and-, this signifies his feeling of emptiness is even apparent in his comment. He was seeking to state that he couldn t believe that he s the lone 1 who has the desire to come out and look at nature. The reader, can comprehend what the cause of it is when there are elans in topographic point of words. He can t ptyalize these words out because he has ne'er experienced the beauty of nature. The Nipponese Quince fascinates Mr. Nilson ; it [ is ] so alive and reasonably. The tree with its pink and white flowers serves an cosmetic intent, since it doesn t do anything so utile as bear fruit. This is a contrast to Mr. Nilson s mechanical life, along with his fathead clock. Mr. Nilson s
life is being a man of affairs, while the fathead clock s life is to start out and sing every hr on the hr to do people cognizant of the clip. Both of these occupations are really mechanical in that Mr. Nilson follows a set agenda mundane and does non diverge from it, while the fathead clock pops out every hr on the hr twenty-four hours after twenty-four hours. It s Mr. Nilson s life in general that is doing him lack spontaneousness. The fathead clock besides is a contrast to the blackbird that is alive and existent. The blackbird produces sweet and tuneful vocals, while the fathead clock produces the same humdrum vocal every hr on the hr. When Mr. Nilson sees the Nipponese Quince, he is dazzled by it because due to his busy life with work, he doesn t have clip to be fascinated with nature.
Mr. Nilson s brush with Mr. Tandram is the concluding development in the secret plan. Mr. Nilson strikes up a small conversation with Mr. Tandram, which entails merely scientific inside informations about the tree. We see that since Mr. Nilson can non depict the beauty of nature in abstract words, but alternatively he must trust on facts to depict the tree. He is ever believing about concern and affecting himself with facts, merely like when he was chew overing on the monetary value of Tintos. When Mr. Nilson sees a C transcript of himself in Mr. Tandram, he thinks to himself, how foolish he must ve looked staring and smiling at the tree, and Mr. Nilson fears this because it is something unknown and a new experience for him. The reader of The Nipponese Quince should recognize that the feeling of emptiness, is caused by losing spontaneousness. At the terminal when Mr. Nilson hears the sound of a cough from Mr. Tandram, he gets disquieted, but doesn Ts know why. This is likely because Mr. Nilson enjoyed his amble through the park. However now he is reluctantly forced to travel back to the mechanical life of a man of affairs.

Study Suggests Women More Likely To Have Nightmares
New research suggests women experience significantly more nightmares than men and have more emotional dreams.
There was no difference in the overall number of dreams reported, said researcher Dr. Jennifer Parker of the University of the West of England.
Previous research has shown women tend to have more disturbed sleep than men.
Changes in a woman's body temperature during her monthly cycle have been linked to such sleep disturbances.
"It has been known for a long time that pre-menstrual women report more vivid and disturbing dreams," said Dr. Parker, a lecturer in psychology.
"The consistent finding in this research was that women report more unpleasant dreams than men."
The women who took part in the study were much more likely to report dreaming about very emotionally traumatic events such as the loss of a loved one.
"In terms of processing emotional information, women may be more prone to taking unresolved concerns into their sleep life." Parker added.
"The research showed a gender difference but what is difficult to pick out is whether women are having more nightmares or remembering them better," said Dr. Chris Idzikowski, director of the Edinburgh Sleep Centre.
He said the results fit in with what's in the literature, as women's sleep tends to be more disrupted and they have more insomnia.
"And more frequent wakening could cause them to pick up on the dream.
"But it could be that disturbed sleep is contributing to the fears."
Nightmares in everyone were probably more common than people realized as they are quickly forgotten about, he added.

Lasers to replace quartz technology
In a new discovery, researchers have found that lasers can safely replace years old quartz technology used in wristwatches or to transmit reliable signals to radios.tech reviews Updated: Jul 18, 2014 16:06 IST
In a new discovery, researchers have found that lasers can safely replace years old quartz technology used in wristwatches or to transmit reliable signals to radios.
In lieu of a crystal, researchers at California Institute of Technology (Caltech) have developed a method to stabilise microwave signals in the range of gigahertz using a pair of laser beams as the reference.
"Our new method reverses the architecture used in standard crystal-stabilised microwave oscillators - the 'quartz' reference is replaced by optical signals much higher in frequency than the microwave signal to be stabilised," explained Kerry Vahala, a professor of information science and technology and applied physics at Caltech.
Nearly all electronics require devices called oscillators that create precise frequencies.
For nearly 100 years, these oscillators have relied upon quartz crystals to provide a frequency reference.
Quartz crystals "tune" oscillators by vibrating at relatively low frequencies - those that fall at or below the range of megahertz, or millions of cycles per second, like radio waves.
However, future high-end navigation systems, radar systems and even consumer electronics will require references beyond the performance of quartz.
In the new method called electro-optical frequency division, the optical reference used by researchers is a laser that looks like a tiny disk.
"At only six mm in diameter, the device is very small, making it particularly useful in compact photonic devices - devices powered by photons instead of electrons," said co-author Scott Diddams, a physicist at Maryland-based the National Institute of Standards and Technology.
The study appeared in the journal Science.

Medical Cardiac Pacemaker
Patent Number(s) 3,057,356
Wilson Greatbatch invented the cardiac pacemaker, an innovation selected in 1983 by the National Society of Professional Engineers as one of the two major engineering contributions to society during the previous 50 years. Greatbatch established a series of companies to manufacture or license his inventions, including Greatbatch Enterprises, which produces most of the world's pacemaker batteries.
His original pacemaker patent resulted in the first implantable cardiac pacemaker, which has led to heart patient survival rates comparable to that of a healthy population of similar age.
Born in Buffalo, New York, Greatbatch received his preliminary education at public schools in West Seneca, New York. In 1936 he entered military service and served in the Atlantic and Pacific theaters during World War II. He was honorably discharged with the rating of aviation chief radioman in 1945. He attended Cornell University and graduated with a B.E.E. in electrical engineering in 1950. Greatbatch received a master's from the State University of New York at Buffalo in 1957 and was awarded honorary doctor's degrees from Houghton College in 1970 and State University of New York at Buffalo in 1984. Although trained as an electrical engineer, Greatbatch primarily studied interdisciplinary areas combining engineering with medical electronics, agricultural genetics, the electrochemistry of pacemaker batteries, and the electrochemical polarization of physiological electrodes.

This collection of toys is one of the Miss Kyoto doll accessories. The set includes a hagoita (battledore) and two shuttlecocks for use in the New Year's game hanetsuki, as well as two otedama bean bags. The hagoita (AB 782 u.1) has a black handle and features a three-dimensional silk flower design on the front; the back is painted with green bamboo plants. The silk of the hagoita is slightly faded with time. The two shuttlecocks (AB 782 u.2-3) have green feathers and black beads. The otedama (AB 782 u.4-5) have alternating panels of red and white silk.
Hagoita are wooden paddles, originating in Japan and used to play hanetsuki, though often serving a more ornamental purpose. They are usually painted, sometimes with lacquer, and feature auspicious symbols or complex, three-dimensional collages with silk, washi paper, or other cloth. Traditional hagoita commonly feature portraits of famous kabuki actors or characters. This tradition dates to the 17th century; decorative hagoita are still produced today. A shuttlecock (also called a bird or birdie) is a projectile used in hanetsuki (and in badminton). It has a conical shape made from feathers attached to a spherical base. The conical shape makes the shuttlecock aerodynamically suited to these types of games. Hanetsuki is a traditional Japanese game played in a similar manner to badminton, but without the use of a net. Hanetsuki is popular during the New Year, and there are two variations: one in which a single person attempts to keep the shuttlecock in the air for as long as possible, and another in which two people hit the shuttlecock back and forth.
Otedama is a bean bag toss game played in a manner similar to jacks.

How do Chumash Indian children live, and what did they do in the past?
Add your answer...
1 Answer
They do the same things all children do--play with each other, go to school and help around the house. Many Chumash children like to go hunting and fishing with their fathers. In the past, Indian kids had more chores and less time to play in their daily lives, just like colonial children. But they did have dolls, toys, and games to play. One favorite Chumash children's game was a contest to throw a javelin through a rolling hoop. Chumash kids also enjoyed swimming on the beaches. A Chumash mother traditionally carried a young child in a cradleboard on her back--a custom which many American parents have adopted now. What were men and women's roles in the Chumash tribe? Chumash men were fishermen and hunters, and sometimes they went to war to protect their families. Chumash women ground acorn meal, did most of the cooking and child care, and wove baskets. Both genders took part in storytelling, music and artwork, and traditional medicine. A Chumash chief could be either a man or a... more

International Project SENARIO
Project title: Advanced Sensors and Novel Concepts for Intelligent and Reliable Processing in Bonded Repairs. Project acronym: SENARIO. Project no.: AST5-CT-2006-030982. Instrument: STREP. Thematic Priority: Aeronautics and Space
The main target of the SENARIO project is to improve the repeatability and reliability of bonded composite repairs to degraded aircraft structure via in-process monitoring and feedback control of the bonding process. The development of sensing (dielectric, wireless and optical) and the integration of material state monitoring to the hot bonder equipment (heating blanket) are among the main technological objectives. In particular, the dielectric sensors for patch materials and the wireless sensors embedded in the bond line during adhesive cure will provide real time information to enable enhanced process control and to facilitate quality control with traceable history of the material conditions. The material modeling activities in the project are particularly significant as the models allow the translation of the sensor signal to actual material condition and the final state of the repair process. Furthermore, the models will allow the use of the sensor signal for closed loop feedback control of the repair process and the increased reliability of the procedures through minimization of variables introduced by different operators.

The Director of Undergraduate Studies can set up an independent study course after a proposal has been received that follows the guidelines below. The deadline for your proposal is the end of the first week of classes however an earlier submission is better in case you you are required to revise your proposal. The DUS can be reached at _EMAIL_.
- If approved, mathematics department staff will e-mail you a section number and a permission number that will enable you to sign up for the course on DukeHub.
- If your proposal needs further work before it can be accepted, you will be informed by e-mail.
Research Independent Study can be used as the basis for Graduation with Distinction.
1. The first step is to download the Request for Independent Study/Independent Study Permission Form. Please complete this form noting the following modifications which are specific to the math department:
- The Description of Proposed Study (Item 1 on the bottom of the permission form) should be typed out on a separate sheet (or sheets) of paper according to the guide below.
- The Nature of Final Product statement (Item 2) and the Grade to be based on statement (Item 4), should include a verbatim copy of the corresponding portions of this webpage below.
2. Work together with your mentor to write the proposal. The length of your Description of Proposed Study will depend on the particulars, but should be ideally between 1-3 pages.
3. In preparing your independent study proposal a good model to follow is a complete course syllabus. While your study proposal doesn't need to be as full as an actual syllabus, it should be more substantial than a bulletin-style course description.
4. Be sure to communicate clearly. You want your proposal to be well organized and carefully written so that your reader will be able to understand what you are writing. While your intended reader will be a mathematician with at least a basic working knowledge of mathematical concepts, they may not be as familiar with specialized terms in a given subfield. These specialized terms – or terms from science, economics, and engineering that may not be familiar to a broad range of well-educated lay people – should be defined in your proposal.
5. Turn in your typewritten sheet (or sheets) together with the completed independent study permission form (signed by you, the supervising faculty member, and the instructor if different) to the Director of Undergraduate Studies for Mathematics. This should be done as early as possible during the first week of classes. It is acceptable to submit your forms as an e-mail attachment to _EMAIL_ (however scanned documents must be "clean" — the background cannot be gray). If the application is not acceptable you will be notified of the problems and you may revise and re-submit. If it is acceptable you will be notified in the second week of classes and given a course/section number and a permission number in order to register.
6. At the end of the semester, on or before the last day of final exams, you mustl e-mail an electronic copy of your final paper to the Director of Undergraduate Studies of mathematics at _EMAIL_.
1. Clearly state the problem you will be working on in as precise a manner as possible.
- The statement should be understandable to a mathematician whose specialty is far removed from the field in which you propose to work.
- It may be necessary to include background information to provide context before coming to the statement of the actual problem.
- In case the source of the problem is outside mathematics, it may be necessary to first discuss the scientific, engineering, or economic context and then explain how mathematics enters in before describing the specific problem itself.
2. What previous work has been done related to the problem?
- Did you work on this problem, or a related problem, during the summer or during a previous research independent study course? If yes, it is important to communicate any previous work that you completed. Please summarize what you did and include an electronic copy of your final paper from a previous semester.
- If others have worked on this problem, you need only summarize what is necessary to set the context for how you propose to approach the subject.
3. Describe how you propose to make progress towards solving the problem.
- What methods will you try?
- Will there be techniques that you need to learn? If so, from what sources will you learn them? List chapters in books or articles in journals.
- What courses have you taken previously which will provide you with some of the background necessary to approach your problem?
4. Proofread carefully what you have typed to be sure that the issues above have been addressed.
The final product for your research independent study will be a formal paper (as opposed to an informal report) that meets the criteria listed below.
1. The paper describes important aspects of the work done during the course.
2. The paper is thoughtful, well organized, and well written. It should be carefully proofread.
3. The paper communicates well to as broad an audience as would reasonably be assumed to have interest in your research topic.
4. The first part of the paper (two pages minimum) describes the broader context in which the project took place. This section should be written in a way that is understandable to an individual who has no specialized knowledge beyond the standard course content regularly offered by the Duke math department.
- Specialized technical terms should be defined or avoided.
- If your project involved a particular problem in a field of pure mathematics, it should be related to broader questions within that field.
- If your project involved an application of mathematics, appropriate background material should be explained to motivate the problem and set it in a suitable context.
- If non-standard mathematical techniques are used, they should be compared to standard techniques.
The final paper may, at the discretion of the instructor, include relevant excerpts from any paper or report that you had written for a previous related independent study course or in connection with a previous related research project. However, such excerpts may only constitute a small portion of your final paper.
Work on the final paper, especially on that part that explains the broader context of the research, may be begun early in the semester.
Student will e-mail an electronic copy of their final paper to the Director of Undergraduate Studies of mathematics on or before the last day of final exams.
The final paper will contribute substantially to the course grade – that is to say, a student will not receive an "A" grade if their final paper clearly fails to meet the criteria listed above under "Nature of Final Product".

A theoretical study on absorption spectra of ofloxacin
Density functional theory (DFT) and Time dependent density functional theory (TDDFT) calculations have been carried out to study the electronic structure and the UV absorption spectra of ofloxacin. The UV spectra have been investigated with inclusion of solvent effect using the polarizable continuum model (PCM). The B3LYP functional with 6-31G(d,p) basis sets have been used for geometry optimization and also to compute absorption energies. The vertical absorption energies both in gas phase and in ethanol were computed. The absorption maximum both in gas phase and in polar solvent is discussed in terms of electrostatic interaction energy, oscillator strength and dipole moment.

Through a close look at the history of the modernist hooked rug, this book raises important questions about the broader history of American modernism in the first half of the twentieth century. Although hooked rugs are not generally associated with the avant-garde, this study demonstrates that they were a significant part of the artistic production of many artists engaged in modernist experimentation. Cynthia Fowler discusses the efforts of Ralph Pearson and of Zoltan and Rosa Hecht to establish modernist hooked rug industries in the 1920s, uncovering a previously undocumented history. The book includes a consideration of the rural workers used to create the modernist narrative of the hooked rug, as cottage industries were established throughout the rural Northeast and South to serve the ever increasing demand for hooked rugs by urban consumers. Fowler closely examines institutional enterprises that highlighted and engaged the modernist hooked rugs, such as key exhibitions at the Museum of Modern Art and the Metropolitan Museum of Art in the 1930s and '40s. This study reveals the fluidity of boundaries among art, craft and design, and the profound efforts of a devoted group of modernists to introduce the general public to the value of modern art.

Soyprotein–jute fiber composites developed using water without any chemicals as the plasticizer show much better flexural and tensile properties than polypropylene–jute composites. Co-products of soybean processing such as soy oil, soyprotein concentrate and soy protein isolates are inexpensive, abundantly available and are renewable resources that have been extensively studied as potential matrix materials to develop biodegradable composites. However, previous attempts on developing soy-based composites have either chemically modified the co-products or used plasticizers such as glycerol. Chemical modifications make the composites expensive and less environmentally friendly and plasticizers decrease the properties of the composites. In this research, soyprotein composites reinforced with jute fibers have been developed using water without any chemicals as plasticizer. The effects of water on the thermal behavior of soyproteins and composite fabrication conditions on the flexural, tensile and acoustic properties of the composites have been studied. Soyprotein composites developed in this research have excellent flexural strength, tensile strength and tensile modulus, much higher than polypropylene (PP)–jute fiber composites. The soyprotein composites have better properties than the PP composites even at high relative humidity (90%).


tbl_name [, tbl_name]...
 [WAIT n | NOWAIT]
OPTIMIZE TABLE has two main functions. It can either be used to defragment tables, or to update the InnoDB fulltext index.
MariaDB starting with 10.3.0
Set the lock wait timeout. See WAIT and NOWAIT.
OPTIMIZE TABLE works for InnoDB (before MariaDB 10.1.1, only if the innodb_file_per_table server system variable is set), Aria, MyISAM and ARCHIVE tables, and should be used if you have deleted a large part of a table or if you have made many changes to a table with variable-length rows (tables that have VARCHAR, VARBINARY, BLOB, or TEXT columns). Deleted rows are maintained in a linked list and subsequent INSERT operations reuse old row positions.
This statement requires SELECT and INSERT privileges for the table.
OPTIMIZE TABLE is also supported for partitioned tables. You can use ALTER TABLE... OPTIMIZE PARTITION to optimize one or more partitions.
You can use OPTIMIZE TABLE to reclaim the unused space and to defragment the data file. With other storage engines, OPTIMIZE TABLE does nothing by default, and returns this message: " The storage engine for the table doesn't support optimize". However, if the server has been started with the --skip-new option, OPTIMIZE TABLE is linked to ALTER TABLE, and recreates the table. This operation frees the unused space and updates index statistics.
Since MariaDB 5.3, the Aria storage engine supports progress reporting for this statement.
If a MyISAM table is fragmented, concurrent inserts will not be performed until an OPTIMIZE TABLE statement is executed on that table, unless the concurrent_insert server system variable is set to ALWAYS.
Updating an InnoDB fulltext index
When rows are added or deleted to an InnoDB fulltext index, the index is not immediately re-organized, as this can be an expensive operation. Change statistics are stored in a separate location. The fulltext index is only fully re-organized when an OPTIMIZE TABLE statement is run.
By default, an OPTIMIZE TABLE will defragment a table. In order to use it to update fulltext index statistics, the innodb_optimize_fulltext_only system variable must be set to 1. This is intended to be a temporary setting, and should be reset to 0 once the fulltext index has been re-organized.
Since fulltext re-organization can take a long time, the innodb_ft_num_word_optimize variable limits the re-organization to a number of words (2000 by default). You can run multiple OPTIMIZE statements to fully re-organize the index.
Defragmenting InnoDB tablespaces
MariaDB starting with 10.1.1
MariaDB 10.1.1 merged the Facebook/Kakao defragmentation patch
MariaDB 10.1.1 merged the Facebook/Kakao defragmentation patch, allowing one to use OPTIMIZE TABLE to defragment InnoDB tablespaces. For this functionality to be enabled, the innodb_defragment system variable must be enabled. No new tables are created and there is no need to copy data from old tables to new tables. Instead, this feature loads n pages (determined by innodb-defragment-n-pages) and tries to move records so that pages would be full of records and then frees pages that are fully empty after the operation. Note that tablespace files (including ibdata1) will not shrink as the result of defragmentation, but one will get better memory utilization in the InnoDB buffer pool as there are fewer data pages in use.
See Defragmenting InnoDB Tablespaces for more details.

Maui Critical Habitat Proposed to Protect 135 Species
By Wendy Osher
The US Fish and Wildlife Service is proposing the designation of critical habitat to protect some 135 plant and animal species in Maui Nui.
The proposed designation of 271,062 acres on Maui, Moloka'i, Lāna'i, and Kaho'olawe, is projected to cost between $115,000 and $125,000, from 2013 to 2022.
In addition to proposing critical habitat for the first time for 50 species, the rule proposes to revise already designated critical habitat for 85 plant species that are listed as endangered or threatened.
More than half of the critical habitat is proposed on lands that are private (53%); with the remaining areas under state (36%), federal (10%), and county (1%) ownership.
Authorities say approximately 47% of the area being proposed as critical habitat is already designated as critical habitat for listed species.
An public informational meeting will be held from 3 to 5 p.m. that will include presentations about the proposed rule and the draft economic analysis followed by a question and answer period, and a 1 hour break. A public hearing will be held from 6 to 8 p.m., which will allow interested parties to provide "on the record" testimony.
Both will be held Feb. 21 at the Kealia Pond National Wildlife Refuge Visitor Center Multipurpose Room off of the Mokulele Highway in South Maui.
Critical habitat is a term in the Endangered Species Act that identifies geographic areas containing features essential for the conservation of a threatened or endangered species, and which may require special management considerations or protection.
Specifying the location of habitat essential for the conservation of the species helps federal agencies identify where to utilize their authorities to benefit the species as required by the act.
Designating critical habitat also helps focus the conservation efforts of other conservation partners, such as state and local governments, non-governmental organizations, and individuals.

The quality control of composite multilayered materials and structures using nondestructive tests is of high interest for numerous applications in the aerospace and aeronautics industry. One of the established nondestructive methods uses microwaves to reveal defects inside a three-dimensional (3-D) object. Recently, there has been a tendency to extrapolate this method to higher frequencies (going to the subterahertz spectrum) which could lead to higher resolutions in the obtained 3-D images. Working at higher frequencies reveals challenges to deal with the increased data rate and to efficiently and effectively process and evaluate the obtained 3-D imagery for defect detection and recognition. To deal with these two challenges, we combine compressive sensing (for data rate reduction) with a dedicated image processing methodology for a fast, accurate, and robust quality evaluation of the object under test. We describe in detail the used methodology and evaluate the obtained results using subterahertz data acquired of two calibration samples with a frequency modulated continuous wave system. The applicability of compressive sensing within this context is discussed as well as the quality of the image processing methodology dealing with the reconstructed images.

As a major mode choice of commuters, public transit plays an important role in relieving congestion on urban transportation networks. A model is developed for cost-efficient operation that optimizes all-stop, short-turn, and express transit services and the associated frequencies by considering heterogeneous demand. For a transit line with given stations and origin-destination demand, the objective total cost function is optimized by considering a set of constraints that ensure frequency conservation and sufficient capacity subject to operable fleet size. A numerical example is designed that is based on a real-world rail transit line to demonstrate the applicability and effectiveness of the developed model. Results show that optimized integrated service patterns and associated service frequencies significantly reduce total cost.

Off-the-Wall: ToCs, Indexes and Bibliographies in OOo Writer
A new way of thinking about and tagging a document's table of contents and other supporting features makes sense and is more convenient.
Indexes and tables is the phrase that Writer uses for tables of contents (ToCs), indexes and bibliographies. The term also covers ToC variants, such as lists of illustrations or tables. At first, the need for the phrase seems momentarily puzzling. If you're like most people, you probably are used to thinking of ToCs, indexes and bibliographies as separate pieces with no relation to one another. That's how most word processors treat them. Roughly half the time, that's how the Writer interface treats them, too.
However, the term exists because Writer doesn't distinguish between these pieces of contents. Lists of figures, tables of contents, indexes, bibliographies--in Writer, all indexes and tables are treated as variations on the same structure. No matter what particular type you are creating, the procedure is identical:
 - Tag contents in the body of a document for inclusion.
 - Format the index or table.
 - Move the cursor to the position for the index or table and create it.
Each step has variations, depending on the type you are creating and, at times, your own preferences. But in each case, the basic procedure is the same.
Tagging Contents
The first step in creating an index or table in an OOo Writer document is to tag its content in the body of the document. The includes titles that appear in a ToC, the words that appear in an index or the scholarly references that appear in the bibliography. In each case, entries can be tagged automatically or manually.
If a document uses styles throughout, then tagging contents for a ToC is easy. By default, Writer ToCs treat all of the outline levels defined in Tools -> Outline Numbering as tagged content. You can select additional styles to be tagged automatically on the Styles tab of Insert -> Indexes and Tables -> Indexes and Tables. Lists of figures and similar ToC variants also have options on the Index/Table tab, many of which also also based on styles. As always, Writer pays dividends to those who use styles. You don't have to use styles to create a ToC, but doing so is by far the simplest choice.
If a document doesn't use styles or if you have a particular style you want to use for a List of Figures or Tables, ToC entries can be tagged manually by selecting Insert -> Indexes and Tables -> Entry. This is the same technique used to add words manually to an index. The main difference is the type you select from the Index field of the dialogue box. Whether you're doing the grunt work for a ToC or an index, you still need to provide the text for the entry, which is the text in the actual body of the document. This entry can be added by selecting text before opening the dialogue box or by typing within the box. You also can select the level of the entry and whether all entries with the same text also should be tagged.
For index tags, you can make the entry a sub-entry. For example, if you already had tagged GNU/Linux, you could make Debian a subentry beneath GNU/Linux. Index contents also can be automated by selecting Alphabetical Index as the Type when you select Insert -> Indexes and Tables -> Indexes and Tables -> Index/Table. From there, select the Concordance file option. A concordance is a list of key words to tag automatically. Setting up a concordance in a manner that is useful takes more planning than you might think at first, but it is an ideal way to index a long project.
Bibliographical entries are added by selecting Insert -> Indexes and Tables -> Bibliography Entry. A bibliographical entry, however, is the citation that appears in the text. For instance, in the APA citation style, the entry in the body of the document might be (Smith: 1999). Unfortunately, the sample bibliographical database that comes with Writer offers misleading examples, but this citation is the short name for the item. Other information can be filled in according to the citation style and whether the source is a book, journal item or some other medium. You don't need to use--and in many cases, can't use--all the fields available for a bibliographical entry. This information can be stored within the document or within a separate bibliographical database.

Reopen the file........... all changes gone
faisal's picture
i craated a ToC with a level upto 3
The ToC get updated
Now i saved the document
But when re opened the same
again the ToC is been evaluavted upto level 9
Why this?
multiple indexes?
Anonymous's picture
If i add one index, and the an index for images only, i get everything messed up. as soon as i edit the second index, the first one gets shitted all over.
i tried creating one of "user specific" type instead of "table of content", but then, i'd need at least three user specific categories, since i have images, tables and graphics. and OO only fives me one.
deleting entries
David Paenson's picture
I find your explanations very helpful.
I do however have a question: Is there a way of deleting all the entries in the text body itself in one go?
Plaese help.
For a better write up on OOo Writer
Ed Matthews's picture
To read a book written by a writer for writers, check out a resources page by Jean Hollis Weber, of Australia. Her book on OOo Writer gives you a great how-to on using the advanced features of OOo described in this article.
Just wanted to clarify "bette
Ed Matthews's picture
Just wanted to clarify "better".
First, I'm very glad to see an article about these features in something besides MS Office Word, b/c while there are a lot of features in MS Word, they are pretty darn kludgy.
Jean's book is just that, a book, a bit more complete and structured than the article. My use of "Better" just means more in depth, a good jumping off place if this article has piqued your interest. Thanks for helping spread the word about OOo.
cheers. no offense meant.

I love these OpenOffice articles to death, and hope they keep coming, but this one needed some serious proofreading something fierce.
pretty unhelpful
Anonymous's picture
As someone with experience beyond the beginner's level using computers and word processors, I would never guess I could find an article on using a word processor so confusing. Is this an example of the notion that *any* documentation is better than none, regardless of how unhelpful it may be? Too bad the apparently useful features of this program cannot be better disambiguated than this. I really, really need to learn better how to use OOo Writer and its advanced features, but articles like this make me just throw up my hands in exasperation. It's almost as if I read nothing at all.
pretty unhelpful: How, specifically?
Randy Kramer's picture
I found the article quite readable but possibly because I was very familiar with the (very) similar features in Word (97 for example).
You would do a lot of us a service if you could go into more detail about what was difficult to understand, and, if possible, why.
Aside: Some articles I find difficult to understand because a lot of time is spent on the details without enough time on the overall pieces and how they fit together. I thought this author did an adequate overview in the first section of the article.
Besides: If you have specific things you don't understand, maybe someone can help you.
Just for the heck of it, here's how I'd summarize a few of the high spots of the article:
* OOWriter can create TOCs, indexes, tables of figures, etc.
* The approach is to go through the document and tag what you want to be included in those tables, then do some processing to create the tables. (Except that headings can automatically be included in the TOC (did it say or am I guessing:) by virtue of an attribute in the styles for various level headings.
* There are no built-in styles for the resulting tables--you have to do some amount of formatting of the tables, especially if you want a result different than the default.
Then there are some detailed instructions of how to do at least some of those steps in the document.
What more could you want?
Try the other way
Anonymous's picture
If you complain about the explaination that someone FOR FREE gives you, and you're not forced to read it, then I suggest you to try the other way: learn it by yourself and write a bettere article... :)
Then you'll acquire the right to complain, but NOT before... :)
Terrible response
Anonymous's picture
That is the most ludicrous, bullshit reasoning I think I've ever heard. If something is crap, then it's crap. Free has nothing to do with it. If your logic is that if you think the article is shit then you should write a better one defeats both the language of criticism and the fact if you don't know how to do something just how are you going to write it? What your saying is that because something is free negates criticism is the key reason free software will never be taken seriously.

Here is some information on debugging Makefiles:
showing symbol values, and showing file dependencies
There's a good Dr. Dobbs article on this topic, by John Graham-Cumming, at:
or printable, all-in-one page, at _URL_
This article describes some macros you can put in your Makefiles to show you the values of symbols, and to show the dependencies that led to a particular target being built. This is handy if you have a complex Makefile that you are trying to debug.
Makefile Debugger
John has also written a Makefile Debugger.
The following articles describe the debugger and how to use it:
The following resources are needed to use the debugger:
Expand the tarballs from these, and place __gmsl, gmsl and gmd in the directory with the Makefile you wish to debug.
Add the following lines to your Makefile:
include gmd
and
all:
 $(__BREAKPOINT)
remake
remake is a patched GNU make with a debugger, better tracing and error reporting. The latest version is based on GNU make version 3.82 released sources.
See: _URL_
Use the option --debugger (short form is -X) in your make invocation. For example:
$ remake --debugger
But much of the time you may be able to get by using just the better tracing that is given. For that use option --trace (short form is -x). For example:
$ remake -x
Debugging a kernel build
Verbose options
There are several Kernel makefile tricks which are helpful for debugging a kernel build.
Try "make V=1 [<rest of make args...>]" to see all the full-length commands used to build the kernel.
Sometimes, if a particular step is breaking and you don't understand why, you can copy-and-paste from this verbose command output (to the shell command line). To do this you need to make sure you are in the correct source directory, and that all required files are present.
To see why a particular target is being build, use "make V=2". This is quite useful when a small change results in much more being build than you expected.
Building in a separate directory
Use the variable KBUILD_OUTPUT either as an environment variable or on the make command line, if you wish to put the build output into a separate directory from the source. This can be useful for several reasons, including when you want to build for multiple architectures from the same source, or when you wish to avoid cluttering up the source tree with object files, libraries and other generated files (to make diffs easier).

How long can come menstruation after weaning? Can lactation come menstruation?
For many mothers, the most concerned question after weaning is how long to menstruate after weaning? The recovery of postpartum menstruation has a certain relationship with breastfeeding. So if you don't have menstruation, don't worry, it will come naturally after weaning!
Generally speaking, if postpartum does not lactate, 1-2 months can resume menstruation, late, postpartum 3 months will also resume menstruation. And lactating women's menstrual tide recovery generally delayed for a long time, may not have menstrual tide in the whole lactation period. But after stopping breastfeeding, menstruation can resume within three months. Those who do not have menstruation beyond this period should go to the hospital to find out the reason.
From the medical point of view, according to the endometrial tissue morphology, as early as 33-42 days after delivery, the ovary can ovulate. In addition, the presence of corpus luteum after ovulation can also be observed at 6 weeks postpartum. How long does menstruation occur after weaning? Under normal circumstances, the mother has experienced menstrual flow during the lactation period. If the baby is weaned after 3 months, of course, some mothers' menstrual flow recovery is slow. There may be no menstrual flow during the whole lactation period, and they will resume normal menstruation after 3 months of stopping lactation.
According to the research data, 40% of the mothers who did not breast-feed resumed ovulation at the 6th week of postpartum, resulting in menstruation; by the 8th to 12th week of postpartum, the proportion of mothers who did not resume ovulation and menstruation was about 35%. If there are mothers who are breastfeeding, the proportion of ovulation recovery and menstruation starts from 12 weeks after delivery is 25%, and the time needed for most breastfeeding mothers to fully recover ovulation function is 18 weeks. However, it is sometimes difficult to determine the exact time of the first menstruation after childbirth in clinical practice, and a few mothers will start to have a small to moderate amount of intermittent bleeding immediately after childbirth.

See also Jupiter in Taurus.
While Jupiter is retrograde, we tend to re-think our goals and plans in the areas of life affected by Jupiter's transit. It's a time of questioning what we thought we already knew and developing a new perspective on events and beliefs.
Recognizing areas of excess or extravagance can help us. We may need to slow down specific endeavors if they've been moving too quickly, or this happens organically. Some enthusiasm may wane as certain realities of time and energy set in.
Gradually over the next few weeks, matters ruled by Jupiter will move forward more straightforwardly. Our confidence in ourselves and the universe builds. Our faith and perspective expand, although as this shift occurs now, problems can seem larger than life.
This direct turn can feel refreshing.
