Definition of Archaeogenetics
Archaeogenetics: The study of the past using the techniques of molecular genetics. The application of genetics to archeology. The term "archaeogenetics" was coined in the 1990s by the archeologist Colin Renfrew from the Greek archaios (ancient) + genetics = archaeogenetics, literally, ancient genetics.
In archaeogenetics, information on the DNA of different ethnic groups from around the world is used to analyze prehistoric events and corroborate accounts from historical sources. The DNA data are reconciled with the findings of archeologists, linguists, and paleoanthropologists to shed light on the past.

Sailors Knot
Sailors Knot
Description: The Sailors Knot is considered a variation of the Josephine knot, but you use two separate cords. There are also two loops, rather than three.
This decorative knot is a great technique to use when making jewelry projects, such as the Leather Bracelet.
You can also use it to link 2 cords together, or as a mounting knot.
Below the main instructions I have shown you two other ways to use this knot; in a sennit (chain), and with an alternating design.
Step 1: You need 2 cords to practice, each at least 36 inches long. Using two colors really helps while you are learning.
 Loop 1
Secure both cords to your board vertically.
Make the first counter-clockwise loop with the cord on the left (brown).
Make sure the working end passes under the secured end to make the crossing point.
 Loop 2
Step 2: Move the cord on the right (green) over the loop, and under the working end of the left cord.
Bring it over the secured end (left cord), as you rotate it clockwise.
 Complete Loop 2 Step 3: Weave the working end of the right cord through the loop made by the left cord, passing under - over - under the three segments.
 Tighten the Knot
Step 4: Tighten the Sailors Knot by pulling on the ends.

Creating a Sennit
 Sailors Knot Sennit
There are two types of patterns that can be tied with the Sailors knot.
The first is a sennit, which is tying several knots in a vertical direction. The knots can be close together, or be separated slightly.
A design like this can be used as a bracelet, a belt, or a strap.
Step 1: Tie the first Sailors Knot following the instructions above, close to one end of the cords. Secure it to your board. The working cords will be the long ends, at the bottom.
 Loop 1
Make a counter-clockwise loop with the working cord on the left (Black).
Make sure the end goes under to make the crossing point.
 Loop 2
Step 2: Bring the working cord on the right (green), over the loop.
Pass it under the working end of the left cord.
Pass it over the segment of the left cord coming from the knot above.
Step 3: Weave the right end through the three segments of the loop, under - over - under.
Pull on the two loops first, to tighten the area above the knot.
Pull on the ends to tighten the loops.
Step 4: Repeat steps 1 - 3 to make the remaining knots in the sennit.
Macrame Cord Divider
Alternating Pattern
 Alternating Sailors Knots
The other way the Sailors Knot can be used is in an alternating pattern, similar to Alternating Square Knots.
Start by securing 3 folded cords to your board, so you have 6 ends to work with.
 First Row
Step 1: Mentally number the cords, moving from left to right.
Make the first row of knots using cords 1 - 2, 3 - 4, and 5 - 6. Tie them as you did in the first set instructions, near the top of the page.
 Second Row Step 2: For the second row, alternate the cords.
The first knot is tied with cords 2 - 3. The following one is tied with cords 4 - 5. Tie them as you did in the second set of instructions (for the sennit).
Design Tip: In the images shown, I left space between the rows to help you see the details. You can either mimic this arrangement when you practice, or place the rows close together.
 Third Row Step 5: Repeat step 2 to make additional rows, alternating the cords each time.

Not quite. chdir() operates on a process and a directory; the pathname
is necessary only to identify the directory. It could equally well
identify the directory by a file descriptor open on it, and that's
exactly what fchdir() does. truncate() operates on a file; the
pathname is used merely to find the desired file. It too could equally
well identify the file by a file descriptor open on it, and that's
exactly what ftruncate() does.
However, unlink() does not operate on a file, except as a side effect;
it operates on a link to a file. The file is affected, sometimes very
mildly, sometimes severely, but the critical point is that the pathname
is not serving just to locate the file, but rather to locate a
particular link to the file. Since file descriptors are on files, not
on links to files, funlink() doesn't really make sense.

Yes, it should be able to. But since you can't open "." if your
current directory is execute-only, it can't. (It'd also be nice to be
able to do one syscall (funlink of this flavor) instead of three
(fchdir, unlink, fchdir).)

Which is why you can't do funlink(), because unlink doesn't operate on
files; it operates on links to files. The file is operated on only in
that it's garbage-collected once it's no longer referenceable. (Which
may be when its refcount goes to zero, or it may be an indeterminate
time later.)
> I've always though the only extremely serious omission in the f*()
> function call set has been faccess()
It doesn't really make sense, unless you also add fopen() (which name
has unfortunately already been preempted by stdio), to re-open a file
with potentially different access rights. Otherwise, faccess() doesn't
tell you anything of use.
> (and of course there should not have ever been an access() call since

How so? Provided you realize what it does, and more importantly what
it doesn't do, there's nothing wrong with it. (In particular, access()
with F_OK is useful to non-setid programs.)

No, it wouldn't. You still couldn't save and restore your current
directory by opening "." and fchdir()ing back there if your current
directory is execute-only, even with O_MKDIR, without O_NOACCESS.

A healthy city is one that continually creates and improves psychosocial and social environments and expands community resources allowing people to develop to their maximum portential. The role of SEDoHs is incontestable, yet we continue to face many of the same SEDoH-related problems despite what we know.
Objectives and Approach
This project presents the idea of "Empathic Cultural Mapping" (ECM). ECM is an interactive story map which brings together vignettes taken from individual stories curated with "big data" derived from places such as Statistics Canada, the City of Calgary, and library holdings at the University of Calgary. ECM seeks to challenge users to re-imagine long held constructions around sectoral, and disciplinary driven interpretations and categorizations of lifestyle, consumption, health, and the environment. ECM seeks to encourage knowledge users from multiple sectors to think beyond what is known and to consider what might be possible.
ECM is a creative interactive undertaking. In developing ECM, a range of creative research processes have been used to record and tell the stories of a small group of newcomers (defined as those who migrate, seek refuge, or claim asylum in Canada) and position these within large data. A desire to improve the health and wellbeing of individuals and communties through opening processes of dialogoue between local government, non-government organizations, communitites, and individuals lies at the heart of this project. Knowledge and sense-making are key features of individual and community empowerment within the ECM and are viewed as powerful stimuli for change as well as powerful allies for health and a buffer against its threats.
ECM creates, shares, and brings together individual stories and 'big data'. It identifies needs that impact health in the everyday. It seeks to improve awareness of the world around us. It encourages people to communicate their experiences. Finally, it achieves its goals by using creative processes.

Water and phosphorus (P) are two critical resources for high nature value farming in semi-dry mountains.
ey are major drivers of grassland productivity but can negatively aect plant diversity. Soil moisture
is known to aect soil microbial activity and plant P nutrition but the eects of irrigation on soil P
status, soil microbial P and plant P nutrition in semi-natural grasslands remain largely unexplored, which
impedes the optimization of fertilization. e aim of this study was to assess the mid-term eects of
irrigation on P availability in the soil, the size of the soil microbial P pool and plant P nutrition in semi-dry
mountain grasslands. At the end of a ve-year irrigation-fertilization factorial experiment on eleven seminatural
grasslands of an inner-alpine valley, soil P availability and herbage P content did not signicantly
dier between the irrigated and the not irrigated treatments. Fertilization increased herbage P content
from 2.2 to 3.1 mg P kg-1 dry mass (P<0.001). e size of the microbial P pool remained unaected by
irrigation and fertilization. We conclude that for semi-natural mountain grasslands, no correction factor
for irrigated compared to not irrigated meadows is necessary to estimate the P fertilization requirement
per unit of herbage yield.


JPL Chief Technologist Lands AIAA Award

Fred Hadaegh
"Believe in your vision and don't get disappointed if people don't immediately jump on the bandwagon." That's the advice of JPL Chief Technologist Fred Hadaegh for other JPLers hoping to make major inroads in technology. Hadaegh has followed that philosophy throughout his career at JPL (since 1984) and has helped the Lab become a world leader in technologies previously deemed improbable by many skeptics.
Hadaegh's "never give up" attitude led to a body of work that is now being honored by the AIAA (American Institute of Aeronautics and Astronautics), which has presented him with its 2021 Mechanics and Control of Flight Award. The award citation praises his "extraordinary contributions for advances in the theory, computation, and implementation of autonomous guidance, navigation, and control of single and distributed spacecraft systems."
The specific work covered involves Hadaegh's technical contributions and leadership in developing the principles and methodologies enabling practical use of multiple spacecraft and telescopes flying in formation, and swarms of hundreds or thousands of small spacecraft. His work has impacted how scientists detect and characterize exoplanets and improve Earth observations, among other capabilities.
"This is extremely humbling, and I'm honored to be selected for this award, which includes past recipients who are among the giants in the field," Hadaegh said. "The award goes to me, but also reflects the work of JPL and collaborators from academia and industry."
The AIAA presented the award to Hadaegh at a virtual ceremony on Jan. 20. A formal reception is being planned for August 2021. This particular award is administered jointly by three AIAA technical committees; Atmospheric Flight Mechanics, Astrodynamics, and Guidance, Navigation and Control.
The organization describes its work as ensuring that aerospace professionals are recognized and celebrated for their achievements, innovations, and discoveries that make the world safer, more connected, more accessible, and more prosperous.
Hadaegh was appointed JPL's Chief Technologist in 2016. Before that, he served as Associate Chief Technologist. He is a JPL Fellow, Senior Research Scientist, and Principal Engineer.
For two decades, he supervised the Guidance and Control (G&C) Analysis Group, which leads research in guidance, estimation, and control theory and develops algorithms and software for planetary science and astrophysics missions. He also led development of G&C technologies for spacecraft formation flying, autonomous rendezvous, and docking for NASA missions and Department of Defense programs.
Hadaegh is a Fellow of the AIAA and of the IEEE (Institute of Electronics and Electrical Engineers). His numerous awards include NASA's Exceptional Service and Exceptional Achievement Medals, The World Automation Congress Lifetime Achievement Award, and a JPL Award of Excellence.

Proc. of the 2013 European Control Conference (ECC) pages:_PHONE_
European Control Conference edition:12 location:Zurich date:17-19 July 2013
Solving the time-optimal path planning problem, where a system is brought from an initial to terminal state in minimal time while obeying geometric and dynamic constraints, has been an active area of research for many years. Very often the problem is divided into a high-level path planning stage where a feasible geometric path is determined and a low-level path following stage where system dynamics are taken into account. This paper combines both approaches for differentially flat systems into a single optimization problem. The geometric path is represented as a convex combination of two or more feasible paths and the dynamics of the system can subsequently be projected onto the path which leads to a single input system. The resulting optimization problem is transformed into a fixed end-time optimal control problem that can be initialized easily. Throughout the paper, the quadrotor, a challenging non-linear system, is used to illustrate the proposed approach.

text: A stochastic model based on first-order Markov chain was developed to simulate daily rainfall. The model is capable of simulating daily rainfall data of any length, based on the estimated transitional probabilities, mean, standard deviation and skew coefficients of rainfall amounts. A study of rainfall probability is an approach to sound planning for any variation of rainfall either small or large. The simulation model has been used successfully to estimate daily rainfall. The Multivariate logistic regression is used to estimate the probability that it is raining. The logistic regression technique is used to compare between the actual and simulation results for a rainfall from January to December in Bangladesh. The probability of occurrence of rainfall is of vital importance in efficient planning and execution of water use program. This study describes a crop-climate simulation model under rainfed conditions in Bangladesh to be used as a tool for analyzing growth and yield to help planning and management of rice production.

This paper examines the impact of CEO turnover from an internal capital allocation perspective. We test whether new CEOs make different divisional investment decisions than their predecessors, and if yes, how would this difference affect firm performance. We find that segment investments respond to factors, such as segment investment opportunity, segment cash flow, and other segments' cash flows, differently after CEO turnover. Evidence also indicates that new CEOs adjust the segments' previous over-investment /under-investment status to match industry average investment level, and they adjust the relative investment preference among divisions. These findings support the argument that different CEOs have their own set of skills and incentives, which directly affect their internal capital allocation decisions after they take over the office. We also examine the affiliation relationship between certain divisions and new CEOs, and find that new CEOs do not make capital allocation in favor their affiliated divisions. Furthermore, the analyses on firm-level internal capital allocation sensitivity do not support the literature about positive relationship between firm performance and the "Q-sensitivity". But, our analyses do find a positive and robust relationship between changes in firm performance and changes in the "cash flow-sensitivity". This suggests that new CEOs making internal capital allocation in favor of their "cash cow" segments are more likely to improve firm performance after CEO turnover.

Taylor polynomials: Square root
if different from the Exponential function or the Sine function because this function is not defined for all values (its domain is not the whole real line), then it has no sense to say that a polynomial approaches the function for all values of x or that the power series converges for all values of x.
We can calculate the Taylor's series at x=0 easily, using Newton's Binomial Theorem, but the function is not defined when x is smaller than -1.
Then our interest is to study what happens when x is greater or equal to -1.
"In the interval (-1, +1) the parabolas approach the original curve more and more as the order increases; but to the right of x = 1 they deviate from it increasingly, now above, now below, in a striking way." (Felix Klein)
We call this interval (-1, +1) 'circle of convergence' of the power series. It is a typical behavior that a power series converges inside the circle of convergence and diverges outside. We understand better the use of the word 'circle' when we go to the Complex Plane.
It is interesting to study what happens at the 'border' points. At the point x = -1, the branch of the original curve which appears in the drawing ends at a vertical tangent, "all the parabolas extends beyond this point but approach the original curve more and more at x = -1, by becoming ever steeper". At the point x = +1, symmetrical to x = -1, the parabolas approach the original curve more and more closely too.
We can see what happens with some functions with singularities, for example, Taylor polynomials (4): Rational function 1."

The answer depends upon what type of Context Diagram you are referring to.
This diagram is the highest level view of a system.
 - IDEF0 Top Level Context Diagrams have a single top-level context diagram and then have optional 'child' diagrams below that. So the answer here would be "Yes."
The IDEF0 process starts with the identification of the prime function to be decomposed. This function is identified on a "Top Level Context Diagram," that defines the scope of the particular IDEF0 analysis.... From this diagram lower-level diagrams are generated.

Informatica Testing Interview Questions and Answers
Informatica Testing Interview Questions and Answers
Informatica Testing Interview Questions and Answers
1. What is Performance tuning in Informatica?
ANS: The goal of performance tuning is optimize session performance so sessions run during the available load window for the Informatica Server. The performance of the Informatica Server is related to network connections.
2. How to increase the session performance?
ANS: Data generally moves across a network at less than 1 MB per second, whereas a local disk moves data five to twenty times faster. Thus network connections often affect on session performance. So avoid network connections.
Flat files: If your flat files stored on a machine other than the Informatca server, move those files to the machine that consists of Informatica server.
Relational datasources: Minimize the connections to sources, targets and Informatica server to improve session performance. Moving target database into server system may improve session performance.
3. How do you handle decimal places while importing a flatfile into informatica?
ANS: While importing flat file definition just specify the scale for a numeric data type in the mapping, the flat file source supports only number data type (no decimal and integer). In the SQ associated with that source will have a data type as decimal for that number port of the source.
Source ->number data type port ->SQ -> decimal datatype.Integer is not supported. hence decimal is taken care.
4. Differences between Normalizer and Normalizer transformation?
ANS: Normalizer: It is a transormation mainly using for cobol sources,
it change the rows into coloums and columns into rows
Normalization: To remove the redundancy and inconsistency
5. What is the target load order?
ANS: You specify the target load order based on source qualifiers in a maping. If you have the multiple source qualifiers connected to the multiple targets, you can designate the order in which Informatica server loads data into the targets.
6. How can you create or import flat file definition in to the warehouse designer?
ANS: You can not create or import flat file definition in to warehouse designer directly. Instead you must analyze the file in source analyzer, then drag it into the warehouse designer.
When you drag the flat file source definition into warehouse designer workspace, the warehouse designer creates a relational target definition not a file definition. If you want to load to a file, configure the session to write to a flat file. When the Informatica server runs the session, it creates and loads the flat file.
7. How do we do unit testing in Informatica?
ANS: Unit testing are of two types
1. Quantitative testing 2.Qualitative testing
8. How do we load data in Informatica?
1. First validate the mapping
2. Create session on them applying and then run workflow.
There you can see how many number of source rows are applied and how many number of rows loaded in to targets and how many number of rows rejected. This is called Quantitative testing.
1. Take the DATM (DATM means where all business rules are mentioned to the corresponding source columns) and check whether the data is loaded according to the DATM in to target table. If any data is not loaded according to the DATM then go and check in the code and rectify it.
This is called Qualitative testing.
This is what a developer will do in Unit Testing.
9. What is Data driven?
ANS: The Informatica server follows instructions coded into update strategy transformations with in the session mapping determine how to flag records for insert, update, delete or reject. If you do not choose data driven option setting, the Informatica server ignores all update strategy transformations in the mapping.
If the data driven option is selected in the session properties, it follows the instructions in the update strategy transformation in the mapping now it follows instructions specified in the session.
10. How the Informatica server sorts the string values in Rank transformation?
11. Define Informatica repository?
12. How can we partition a session in Informatica?
ANS: Partitioning option optimizes parallel processing on multiprocessor hardware by providing a thread-based architecture and built-in data partitioning.
The Power Center Partitioning option enables hardware and applications to provide outstanding performance and jointly scale to handle large volumes of data and users.
13. In update strategy target table or flat file which gives more performance? Why?
14. What is parameter file?
ANS: When you start a workflow, you can optionally enter the directory and name of a parameter file. The Informatica Server runs the workflow using the parameters in the file you specify.
15. What are variable ports and list two situations when they can be used?
16. Can you start a session inside a batch individually?
ANS: We can start our required session only in case of sequential batch. In case of concurrent batch we cant do like this.
17. What are the types of lookup caches?
1) Static Cache
2) Dynamic Cache
3) Persistent Cache
4) Reusable Cache
5) Shared Cache
18. What are two types of processes that Informatica runs the session?

Flat rocks can be used in the design of your garden or lawn and enhance the curb appeal of your property. They can complement an existing garden or replace greenery entirely in favor of a rock aesthetic to make your front and back yard distinct.
Use flat rocks, especially flagstone, to create a stone pathway that leads to your front door. A flat-rock pathway also can help you and your visitors avoid rough patches in your front yard.
Either lay flat rocks in grass or carve them into soil or a rocky terrain. You also can lay flat rocks on sod or leveled sand. The most important aspects of creating a flat-rock pathway are to ensure the rocks align evenly and no more than about 1 inch of space is between the rocks.
You have the choice of buying different shapes of flat rocks to enhance the path's visual appeal. Flat rocks that are granite or flagstone can add color and flair to your landscaping scheme.
Steps for a Sloped Yard
Using flat rocks is an ideal way to create steps in a yard that slopes. If, for example, you have a steep decline from a patio, you could install flat rocks to form steps that provide safety and add beauty to your yard. Dig out enough soil and level each area of sloped land where you want to install flat rocks so they will lay flat and secure.
Consider using the same kind and color of rocks for each step to create a seamless look. If you want something more bold, then choose rocks of different types and colors for a look that is attention-grabbing and distinct. Edging the flat-rock steps with a flower arrangement will make them stand out even more.
A fountain can add class, elegance and style to your back yard, and one style you can choose is a flat-rock fountain. That kind of fountain consists of slabs of flat rocks stacked on top of each other, and a number of configurations can be used. For example, you can create a flat-rock fountain with similarly sized rocks except for the top slab, which can be wider and lengthier, allowing the fountain water to flow downward with greater force. You also could create a fountain in which flat rocks that are slate or granite are cut into rectangular shapes and placed in the structure's base, giving you a fountain that has the appearance of a monument, with water running down each side.
Use flat rocks in your flowerbed to beautify your home and to prevent the growth of weeds, which won't grow on rocks. Also, colorful butterflies are like flying flowers in a garden, and flat rocks help to attract them. Butterflies are drawn to the warmth of flat rocks in sunny spots, spreading their wings for the warmth while resting on the rocks and beautifying the garden at the same time.

If something or someone is 'unique' it is special and different from other things like it. Notice the following:
 1. A lot of his ideas are unique, but I don't really agree with him.
 2. Those earrings are really unique. Where did you get them'
On a clear day, when the sun sets at dusk, the water turns from blue to gold.
'Dusk' is the time of day when the such is going down, but there is still a little bit of light. Notice the following:
 1. You need to arrive before dusk, because it's really dangerous to drive on this road at night.
 2. I can see just fine during the day, but at dusk things start to get a little unclear. I think I'm going to buy glasses.

The Golden Gate Bridge is beautiful to look at, but the Bay Bridge is a beautiful bridge to look from.
When you 'look at' something you are viewing it from a place that is a little far away, you are standing off of the bridge and viewing it. If you 'look from' a place it means that you are standing in that place at looking at the things around it. The example is saying that one bridge is beautiful, but the view from the other one is beautiful. Notice the following:
 1. Come over here and look at this sofa. What do you think?
 2. The best part of climbing the mountain is looking at the city from the top.

Porphyrin Deposits in Gerbils
Porphyrin is a pigment, a component of blood cells that functions to bind metal in the blood cells such as iron and magnesium). It is also recognized for being the major component in the the coloring of blood, as porphyrin is a deep purple pigment. In gerbils, in times of stress, the unbound porphyrin can leave deposits in the tear ducts, causing red colored stains around the eyes and nose as the tinted tear fluid leaves the eyes. These stains are often mistaken for blood, and must be differentiated.
Porphyrin deposits cause skin irritation and the gerbil may scratch incessantly to relieve the itching. The causes for porphyrin deposits are related to stress and nutrition, which can generally be easily remedied, but complications can arise due to secondary bacterial infections that result from scratching at the skin until it is bleeding, leaving open sores.
Symptoms and Types
- Reddish-brown deposits of porphyrin around the eyes and nostrils (may be mistaken for blood)
- Skin irritation
- Constant scratching of the face
- Hair loss on the affected area
- Red and inflamed skin around the face
- Scabs/sores on the face
- Bleeding from sores due to severe scratching
- Secondary infections of the sores
- Environment stress – not comfortable due to location; sudden move in location; temperature (too high or low) or light related
- Humidity higher than 50 percent in the living area
- Nutritional deficiency
- Underlying illness
- Inability to get along with cage mates – due to either incompatibility or aggression
- Overcrowding – cage is not large enough, or there are too many gerbils in the same living space
Your veterinarian will perform a thorough physical exam on your gerbil, taking into account the background history of symptoms and possible underlying or environmental conditions that might have led to this condition. You will need to provide a thorough history of your gerbil's health leading up to the onset of symptoms. If secondary skin infection is present due to scratching induced sores, your veterinarian will need to take fluid and tissue samples for bacterial cultures in order to identify the specific bacteria for treatment.

Restructuring and insolvency law in Germany
1. What is the primary legislation governing insolvency and restructuring proceedings in your jurisdiction?
The German Insolvency Code and the European Regulation on Insolvency Proceedings (2015/848) are the primary pieces of legislation governing insolvency proceedings in Germany. So far, there are no pre-insolvency restructuring proceedings regulated by statute under German law. Restructuring proceedings outside of insolvency proceedings are basically directed by the regular corporate and labour law regulations. On 18 September 2020 the Federal Ministry of Justice presented a draft bill on the pre-insolvency restructuring framework (Act on the Stabilisation and Restructuring Framework for Businesses). The law will come into effect on 1 January 2021.
2. How are insolvency proceedings or restructuring proceedings initiated?
Since there are no restructuring proceedings regulated by statute in Germany, only insolvency proceedings can be initiated. The initiation of insolvency proceedings always presupposes the filing of an insolvency petition. Such a petition can be filed either by the insolvent debtor or by a creditor. The insolvency petition must be based on the existence of a reason for the institution of insolvency proceedings. Otherwise the court will not initiate insolvency proceedings.
The following reasons for the institution of insolvency proceedings exist under German law: illiquidity, over-indebtedness and imminent illiquidity. While the petition for the institution of insolvency proceedings of a debtor can be based on any of these three reasons, a creditor's petition cannot be based on imminent illiquidity as a reason for the institution of insolvency proceedings.
Illiquidity occurs if a debtor is unable to meet its due payment obligations. The debtor is presumed to be illiquid if it is not able to pay at least 90 % of its due obligations during the following three weeks. Furthermore, illiquidity is also presumed as a rule if the debtor has stopped making payments.
Over-indebtedness as a reason to file for insolvency applies only to legal entities (limited liability companies, stock corporations and comparable entities). Under German law over-indebtedness occurs if the debtor's assets (based on liquidation values) no longer cover its liabilities in a winding-up scenario (balance sheet test). In addition to this, over-indebtedness requires the debtor not to have a positive going concern prognosis. On the assumption that effects from restructuring measures are likely to occur, an integrated financial plan, based on a viable restructuring concept, needs to show that the debtor will have enough liquidity to meet its payment obligations during the ongoing and the following financial year.
Imminent illiquidity
Imminent illiquidity means that it is more likely than not that the debtor will not be able to meet its due payment obligations in the near future. In order to prove imminent illiquidity the debtor needs to present a liquidity plan showing a lack of liquidity within a period that – according to the prevailing view in legal commentary – must include the current and the following fiscal years. Only the debtor may make use of imminent illiquidity as a reason to apply for insolvency as a restructuring measure.
4. Which different types of restructuring / insolvency proceedings exist and what are their characteristics?
In general, insolvency proceedings are separated into two phases – preliminary insolvency proceedings and the (actual/opened) insolvency proceedings.
After an application for insolvency, the competent court ("Insolvency Court" at the local court) orders measures to protect the debtor's assets (e.g. appointment of a preliminary insolvency administrator, suspension of enforcement/foreclosure, etc.). The preliminary insolvency administrator also reports to the Insolvency Court if the requirements for the opening of insolvency proceedings are met.
The debtor usually stays in possession during the preliminary phase. If necessary, the Insolvency Court may rule that the right to manage and dispose of the debtor's assets is transferred to the preliminary insolvency administrator. In this case, the preliminary insolvency administrator has almost the same powers as an insolvency administrator. Preliminary proceedings usually take 6 to 12 weeks and result in the opening of insolvency proceedings if the requirements are met.
Once the Insolvency Court has decided to open insolvency proceedings, the right to manage and dispose of the debtor's assets is transferred to an insolvency administrator who gains full control over the debtor's business and assets. Enforcement/foreclosure actions remain suspended. Ongoing litigation is automatically suspended but may be continued by the insolvency administrator if appropriate for the insolvency estate. The insolvency administrator will continue the business operations of the debtor if reasonable and possible or to wind up the company. The method by which the debtor's assets are realised (e.g. liquidation, share deal, asset deal, restructuring) needs to be coordinated between the insolvency administrator, the creditors/creditors' committee and the Insolvency Court. The insolvency administrator is obliged to assert and enforce claims of the debtor. The insolvency administrator is bound to aim for the best possible realisation in the interest of the creditors.
Any court orders on preliminary protective measures and on opening of insolvency proceedings must be announced publicly on a database accessible via However, in exceptional cases during preliminary insolvency proceedings, the Insolvency Court may refrain from making a public announcement.
Apart from the regular (preliminary) insolvency proceedings it is also possible to carry out (preliminary) insolvency proceedings in self-administration (debtor in possession). In principle, the procedure of insolvency proceedings in self-administration does not differ much from the regular proceedings described above. The main difference is that the debtor (i.e. its management) remains in charge and the Insolvency Court appoints a custodian (Sachwalter) to supervise the debtor. The right to manage and dispose of the debtor's assets remains with the debtor. Self-administration is often used for larger companies suitable for restructuring, if the know-how of the management is necessary to continue operating the business. In such cases, an insolvency plan is frequently used to implement restructuring measures or a corporate transaction. However, insolvency plans are not limited to self-administration
5. Are there several types of creditors and what is the effect of a difference?
The German Insolvency Code distinguishes between
 1. "normal" (i.e. not subordinated and unsecured) insolvency creditors;
 2. subordinated creditors;
 3. preferential creditors and
 4. secured creditors.
Unsecured insolvency creditors (i) are usually satisfied with a single-digit dividend on their claims, whereas (ii) preferential creditors' claims (usually created by an insolvency administrator after the opening of insolvency proceedings) are satisfied in full from the insolvency estate (unless the estate is not sufficient to cover all preferential claims. In exceptional cases a preliminary insolvency administrator may also create preferential claims). Subordinated creditors (iii) only receive a dividend at all if all normal insolvency creditors (i) have been fully satisfied. Lastly, secured creditors (iv) may be satisfied partly or in full by the proceeds of their security, while their unsecured claims are only satisfied by way of a small dividend
6. Is there any obligation to initiate restructuring / insolvency proceedings? For whom does this obligation exist and under what conditions? What are the consequences if this obligation is violated?
Section 15a German Insolvency Code sets out a strict obligation of representative bodies of a company to file for the institution of insolvency proceedings. A prerequisite for the filing obligation is the occurrence of illiquidity or over-indebtedness (see 3. above). If the company is only imminently illiquid, the members of the representative bodies are entitled, but not obliged, to file a petition for the institution of insolvency proceedings.
The petition has to be filed "without undue delay" but in any event within 3 weeks of the occurrence of a reason for insolvency. The period of 3 weeks can only be made use of if there is still an opportunity to eliminate the reason for insolvency with a predominant degree of probability within the period. If it turns out that attempts to "rescue" the company during the period fail, the members of the representative bodies have to file for insolvency immediately and are not allowed to wait until the period has expired.
If the representatives fail to file for insolvency in time, they face several civil and criminal law risks. Each representative can be held personally liable for damages resulting from a late filing of an application for insolvency. Furthermore, the failure to file for insolvency may be punished under the German Criminal Code. The penalty ranges from a fine to imprisonment of up to 3 years for intent and from a fine to imprisonment of up to 1 year for negligence
7. What are the main duties of the representative bodies in connection with restructuring / insolvency proceedings?
In general, the law requires that representative bodies are fully aware of the financial situation of the company at all times, especially during financial difficulties. They have to undertake reasonable efforts to overcome the reasons for insolvency, e.g. by pursuing restructuring measures with immediate effect.
If the registered share capital of a legal entity has been reduced to half or even less, the representative bodies are required to inform all shareholders about this fact immediately. A failure to comply with this obligation may lead to personal civil liability as well as to criminal consequences (imprisonment of up to 3 years) for the members of the representative body.
The representative bodies of a company have the duty to supervise the existence of a reason for insolvency to ensure that a petition for the institution of insolvency proceedings is filed in due time (for consequence of a belated filing see 6. above).
In addition to this, the representative bodies can be

Physical rehabilitation in Kansas City involves a variety of exercises, including exercises that focus on range of motion. These exercises are designed to help improve and expedite the range of motion. The range of motion is one of the key areas that physical rehabilitation in Kansas City works to improve.
Range of motion defines the extent of movement a particular joint can make at one attempt. If range is affected, it is challenging or impossible to move a specific part of the body around the joint area. It is common for athletes and non-athletes to experience injuries or accidents that impact or limit their range of motion.
Here are a few of the most common triggers that affect range of motion:
- Sprained joints
- Lack of movement or activity following surgery
- Lack of physical activity or exercise in general
Exercises designed to improve range of motion help to reverse the impairment and reinstate free and unrestricted movement of the muscles and joints. Physical rehabilitation in Kansas City introduces basic exercise techniques to correct impaired range of motion. Most importantly, they help to restore range of motion without causing further damage to the affected joint area.
Here is a brief overview of those exercises:
Passive exercises: these exercises are impactful for joints that are no longer active as a result of paralysis or injury.
Active-assistant exercises: these exercises are performed with some assistance from the physical rehab tech. Patients perform the majority of the movements but the rehab tech helps to ensure that the movements are done correctly.
Active exercises: these exercises are performed with little help from the rehab tech, because the patient can complete them on their own. The tech may offer verbal advisement about execution or posture during the exercises.
Range of motion exercises are extremely beneficial in improving the movement of joints that have been damage or injured. Physical rehabilitation in Kansas City is an effective option for those looking to find relief for joint pain and damage.

Introduced in SQL Server 2005, TABLESAMPLE allows you to extract a sampling of rows from a table in the FROM clause. The rows retrieved are random and they are are not in any order. This sampling can be based on a percentage of number of rows. You can use TABLESAMPLE when only a sampling of rows is necessary for the application instead of a full result set.
TABLESAMPLE SYSTEM (10 PERCENT)
TABLESAMPLE SYSTEM (1000 ROWS)
If you run above script many times you will notice that different numbers of rows are returned everytime. Without any data changing, re-running the identical query keeps giving different results. This is non -deterministic factor of TABLESAMEPLE clause. If table is static and rows are not changed what could be the reason to return different numbers of the rows to return in each execution. The factor is 10 PERCENT is not the percentages of the table rows or tables records, it is percentages of the table's data pages. Once the sample pages of data selected, all the rows from the selected pages are returned, it will not limit the number of rows sampled from that page. Fill factor of all the pages varies depends on the data of the table. This makes script to return different row count in result set everytime it is executed. The REPEATABLE option causes a selected sample to be returned again. When REPEATABLE is specified with the same repeat_seed value, SQL Server returns the same subset of rows, as long as no changes have been made to the table. When REPEATABLE is specified with a different repeat_seed value, SQL Server will typically return a different sample of the rows in the table..
Following example is from BOL:
The following example returns the same set of rows every time that it is executed. The seed value of 205 was chosen arbitrarily.
SELECT FirstName, LastName
TABLESAMPLE (10 PERCENT)
REPEATABLE (205) ;

Water Tanks
We all know that water is one of the most precious things that we have and we also know that it can get pretty scarce at times and as a result rain water tanks have now become compulsory in new built homes in most states across Australia.
Architect Sally Dominguez wanted to do her bit for sustainability and didn't have space for a traditional tank so she designed one herself. The difference between the waterHOG and a lot of other tanks is that it's small in size but the designed so that you can slot as many of the tanks together as you need or have space for. It can go up against a wall; it can go under a deck, under the ground, down in the basement, upright or lying down. $260
TankMaster Donut and Bagel Underground
As the name suggests these tanks need to go underground. The Donut shape holds 3000 litres and costs $2775. The Bagel holds 5000 litres and costs $3873. This design is great if you want your tank out of sight, but it is hard to detect any leaks or make any repairs once it's installed.
So if you got a house and use water, it's time to take in a tank. You'll be helping to create a sustainable future and your water bills will be way down. You know councils give rebates of up to $600.

Both Cloud Datastore and Firestore automatically index most of the fields in your database models.
For example, if you use Cloud Datastore with Python 2 on the Standard GAE Environment, you'd create your database model like this:
class User(ndb.Model): name = ndb.StringProperty() age = ndb.IntegerProperty() active = ndb.BooleanProperty()
By default, all three fields would be indexed. But if you don't want some (or any) of them to be indexed, you can set their
indexed attribute as False:
class User(ndb.Model): name = ndb.StringProperty(indexed=False) age = ndb.IntegerProperty(indexed=False) active = ndb.BooleanProperty(indexed=False)
You can read more about optimizing indexes in this article: Optimizing Indices In Google Cloud Datastore - How And Why?
But what if you use the new GAE Python Standard Environment, which uses Python 3 and Cloud Firestore?
You'd have to disable field indexing via the Firebase Console.
Open your Firestore database in the Firebase Console. Click on Indexes and choose the Single field tab.

Alligator shear
From Wikipedia, the free encyclopedia
 (Redirected from Crocodile shears)
Jump to: navigation, search
An alligator shear, historically known as a lever shear[1] and sometimes as a crocodile shear,[2] is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears, however there are types for excavators. The jaw size can range from 4 to 36 in (100 to 910 mm) long. They are generally used to cut steel members, such as rebar, pipe, angle iron or I-beams.[3][4]
Older alligator shears were powered by a flywheel. These shears ran continuously, which posed a safety hazard. Now alligator shears are hydraulically actuated. When actuated, the piston arm extends and slowly closes the upper jaw of the alligator shear, which passes alongside the bed or lower jaw of the shear to perform the cut.[4]
Alligator shears are used for cutting long-length metal stock or scrap, generally where accuracy is not an important consideration, and the size or shape of the material makes other cutting or shearing options impracticaloften the only other cutting option is cutting with a torch. Alligator shears are often used in conjunction with large metal shredders in the metal recycling industry, to 'clean' or prepare scrap for shredding by removing unwanted fittings or other parts the shredder will not accept.
The safety requirements for other powered metalworking shears are contained in ANSI B11.4, but alligator shears are specifically exempted from that standard. Federal OSHA and various state OSHA programs have requirements for guarding alligator shears, and newly manufactured alligator shears are provided with guards that adjust to the size of the stock or scrap being cut. The purpose of this guard, however, is to prevent pieces of metal from being ejected during cutting. Such a guard also prevents inadvertent exposure of the operator's hands, but does not conform to more stringent 'point of operation' guarding requirements.
In an interpretive letter dated June 24, 1981, Federal OSHA discussed the guarding dilemma presented by the alligator shear.
In instances where the shear is exclusively used for routine cuts on standardized stock, safeguarding of the point of operation is definable. In other instances, the operator is safeguarded from exposure to the point of operation by the physical size and configuration of the material being cut.
These practical considerations for guarding are not exclusive to alligator shears. A much more common type of equipment, the press brake, also requires point of operation guarding when used with standardized stock, but not with large-dimension stock.

One of the inspirations for the painting was this 1897 painting of Laelaps by Charles Knight (_PHONE_). Knight was one of the founding figures of paleoart, working more than a century ago.
He started out by drawing living animals at the zoo, then studied animal anatomy and worked at the American Museum of Natural History. Despite obstacles like vision problems, he went on to paint many murals and illustrations reconstructing extinct life forms. His work has influenced several generations of artists and filmmakers throughout the 20th century.

The Oxford English Dictionary defines a post as (1) a support or column of timber, (2) a stand for displaying notices, and (3) a vehicle or vessel used to carry letters and other postal matter. In this essay, I will elaborate the significance of the digital post in relation to these definitions. I argue that the digital post connotes these meanings in a variety of ways, but is ultimately distinct. Thus, an understanding of the digital post necessitates an understanding of its roots. The OED definition implies that a post is a foundation upon which more complex systems are built and maintained. As a stand for displaying notices, the post is a mass address and a social practice. Likened to the postal system, digital posts make up a networked medium that redefines spatial and temporal limitations in the transportation of information.
As an act of publication, the post's purpose is to convey ideas by mediating the mind into a form that is movable, comprehensible, and capable of reaching others. It forms relationships between individuals and disseminates information over spatial and temporal boundaries, forming a network. Through an examination of its etymology, the post is revealed as representing two disparate network structures: the centralized network of the post for displaying public messages, and the linear network of the postal system. The critical differentiating factor between these two network forms is the intended audience of address.
The post of the public notice attempts to address all of the members of the network. It does so from a centralized position of prominence, and is incorporated into the systems of power of the network. Access to the ability to publish, whether limited to a particular group, or available to all members of the network has no bearing on access to the posted publications. The centralization of the system ensures that all members of the network have equal access to it.
The post of the postal system, though, directs a distinct and singular message to an intended and specified addressee, ensuring adherence "to certain established standards of regularity, speed, and security." The network shape of any postal message is linear and unidirectional, with the information moving from sender to addressee. It is important to note that an examination of the postal system as a network, as opposed to the postal message, would reveal a distributed structure. However, this network is irrelevant to this discussion, as it addresses the shape of a system of aggregated and unrelated posts, and does not address the post itself.
In stark contrast, the digital post is capable of simultaneously embodying both network forms, resulting in an unprecedented structure. In this network, the post has a specific addressee, but is differentiated in that these connections are accessible to the entire network. Unlike the publication of an "open letter," which does not ensure that the intended recipient obtains the letter, the digital post is delivered directly to the addressee. However, the digital post is no less private than the posting of a public notice. The resulting network shape of a singular digital post is entirely distributed, while simultaneously being uniquely linear. It is best understood as a system of connected nodes, where all the nodes and connections are available to every other node in the network.
Hence, the digital post is the dominant communicative form connecting the digital social network, as compared to "messaging" and "friending." "Post" spans the spectrum of digital platforms and networks that serve to connect individuals via networked computers. The content or message of the post can encompass a wide range of media, with little preference given to any particular medium. Some of these media are more traditional forms, including text, picture, and video, while others are more particular to the social networking environment, such as "liking," "linking," and "poking." The important distinction is that the post as a medium creates value independent of its content.
Due to its complexity, I believe it beneficial to approach the post as an environment through which the personas and avatars represented by "profiles" live, grow, and interact. Doing so, advances us past the materialistic conception of a medium, and allows us to understand the post as a social practice of "digital identities," embodied forms represented in a digital space. I would like to suggest that it is the post, and not the profile, that forms the basis for the digital identity, as it is the post that confirms the "life" of the profile. Once set up, the profile can exist without a sender or a receiver, and as such only confirms the existence of a data pattern on a server. If the profile is not generating posts, it becomes, in way, dead. Without posting, there is no way to confirm the existence of the inferred embodiment implied by the profile. Alternatively, the post is the pulse of the digital identity. Not only does it substantiate the digital identity, but it can also tell us how the identity lives, its state of health, level of activity, and relation to other identities. As such, it is the post and not the profile that links the digital identity to its embodied, analog, user.
As the representation of a social practice, the post can be understood in Peirce's terms of icon (a physical resemblance), index (a corollary sensory indication), and symbol (an arbitrary representation). The post operates as an index on the basis of its objectness, pointing to the existence of a specific digital identity and its relative placement in a network. A symbolic understanding exposes the post as content that can be interpreted to reveal aspects of the identity it represents. However, the post cannot serve as an icon because the abstract nature of the digital identity resists iconic representation. Furthermore, the post itself opposes iconic representation by not being consistently grounded in a particular physical shape, format, or form.
When identity exists without iconic representation, there is no representation of the identity as form. In her book on post-humanism, Katherine Hayles raises that when an identity becomes heavily dissociated from its surface representation and heavily mediated by technology, the identity becomes dependent on that technology. For Hayles, the human becomes post-human when engaged in an extensive form of heavily mediated representation. I believe the digital post is a condition of possibility for the formation of post-human identities, as it transforms the identity of an embodied presence into an aggregate of patterned information contingent on its mediated production. To build upon Hayles, I argue that the digital identity conferred by the post is a post-human identity, and that the post-human and posting human are undifferentiated.
On the basis of these singular qualities, the digital post has established a precedent by which the commodity can enter into the digital social network to represent itself. This expansion of capitalism may be the most exceptional effect of the post, as older mediums limited commodities to mediated forms of representation, like the logo or spokesperson. These forms cannot embody the commodity, but only serve to represent it in the abstract. Conversely, the adoption of the post by companies and products bestows commodities with a digital embodiment free from iconic representation. This allows an intensification of commodity fetishism, as commodities are able to represent themselves in digital space and engage in new relations with markets and individual consumers. Through the post, the commodity and the person are reduced to the same pattern of representation. Their capacity to interact with the network becomes analogous, forming indistinguishable expressions of identity.
In many ways the post has produced the ultimate self-amputation by means of technology, allowing for the complete externalization of the self. I can look at a computer screen and observe my own digital identity. This is not akin to looking in a mirror. The identity that is established by the post is distinct, and although reflective, it is not a reflection. Currently, this digital identity requires a physical embodiment to provide the keystrokes that massage the medium of the post into the correct shape. However, it would be folly to assume the post is imperatively dependent on a physical embodiment. It need not be so. The post is many things; foundational, representative, informational, and has become the medium in which the digital identity communicates. But above all the post gives life to the digital identity, thereby substantiating it. Constituo, ergo sum: I post, therefore I am.

The objective of this procedure is to show you how to use an oxyacetylene torch for heating. Wear a leather apron or similar protective clothing and welding gloves when using an oxyacetylene torch and always use proper welding goggles.
Part 1. Preparation and safety
- Use an oxyacetylene torch for heating.
Whenever you perform a task in the workshop you must use personal protective clothing and equipment that is appropriate for the task and which conforms to your local safety regulations and policies. Among other items, this may include:
- Work clothing - such as coveralls and steel-capped footwear
- Eye protection - such as safety glasses and face masks
- Ear protection - such as earmuffs and earplugs
- Hand protection - such as rubber gloves and barrier cream
- Respiratory equipment - such as face masks and valved respirators
If you are not certain what is appropriate or required, ask your supervisor.
- Oxygen and acetylene cylinders must be securely stored in an upright position.
- An oxyacetylene torch can produce a large amount of heat. Be aware that any objects you direct the flame towards will become hot.
- Always have a suitable fire extinguisher near your work area.
- Do not use an oxyacetylene torch near any flammable materials.
- Make sure that you understand and observe all legislative and personal safety procedures when carrying out the following tasks. If you are unsure of what these are, ask your supervisor.
Points to note
- If a cylinder falls over and breaks the main valve off, the cylinder will become a missile and cause extreme damage.
- Wear a leather apron or similar protective clothing and welding gloves when using an oxyacetylene torch. T-shirts, nylon and polyester blend clothing will not provide enough protection. Ultraviolet light and sparks of hot metal will pass through them.
- Always use proper welding goggles. Do not use sunglasses because they do not filter the extreme ultraviolet light as effectively. The plastic used in sunglass lenses will not protect your eyes from sparks.
- Never point the lighted flame toward another person or any flammable material.
- Always light the oxyacetylene torch with the striker. A cigarette lighter or match would put your hand too close to the igniting tip.
- Wherever possible, use a heat shield behind the component you are heating. This will prevent nearby objects from becoming hot.
- After heating a piece of metal, label it as "HOT" with a piece of chalk so that others will not attempt to pick it up.
Part 2: Step-by-step instruction
- Light the torch and adjust neutral flame
Light the torch and adjust the gas flow so that you have a neutral flame.
- Heat for 'Removal'
Place a flywheel and ring gear assembly on a set of insulating spacers, to elevate it from the working surface. Direct the flame onto the ring gear and apply the heat until smoke starts to appear. Stop applying the heat. At this stage, the ring gear is hot enough to remove by gently tapping with a hammer and drift. DO NOT TOUCH the metal with your hands. Use welding Gloves and tools that are designed for use in a hot environment.
- Heat to 'Red Hot'
Direct the flame to the component you wish to heat. If the component is made from thin metal it will heat quicker than one that is thicker. Apply the heat evenly, until you notice the object begin to glow red. Once the glow is uniform, the metal will now be hot enough to manipulate. Once again DO NOT TOUCH the metal with your hands. Use welding gloves and tools that are designed for use in a hot environment.
- Shut down
When you have finished the job, you will need to shut down the equipment. Turn off the acetylene valve on the torch handle. This will extinguish the flame. Turn off the oxygen valve on the torch handle. Next, remove your safety goggles or mask and your welding gloves. Turn the main cylinder valve clockwise on the top of both gas cylinders. Now open the two valves on the torch handle to "bleed" the system. Turn both the oxygen and acetylene regulator handles counter-clockwise until they are loose. Close both valves on the torch handle. Put the handle and tips away, and return the gas cylinders and their hoses to their proper storage area.

Similar to ConstraintLayout, Contour works by creating relationships between views' position and size. The difference is, instead of providing opaque XML attributes, you provide functions which are directly called during the layout phase. Contour calls these functions "axis solvers" and they're provided using layoutBy(). Here's an example:
class BioView(context: Context) : ContourLayout(context) {
 private val avatar = ImageView(context).apply {
 scaleType = CENTER_CROP
 private val bio = TextView(context).apply {
 textSize = 16f
 text = "..."
 init {
 x = leftTo { parent.left() }.widthOf { 60.xdip },
 y = topTo { }.heightOf { 60.ydip }
 x = leftTo { avatar.right() + 16.xdip }.rightTo { parent.right() },
 y = topTo { }
 contourHeightOf { bio.bottom() }
Runtime Layout Logic
Because you're writing plain Kotlin, you can reference other Views and use maths in your lambdas for describing your layout. These lambdas can also be used for making runtime decisions that will be evaluated on every layout pass.
 x =...
 y = topTo {
 if (isSelected) + 16.ydip
 else avatar.centerY() - bio.height() / 2
 }.heightOf {
 if (isSelected) bio.preferredHeight()
 else 48.ydip
When paired with an animator, your runtime layout decisions can even act as keyframes for smoothly updating your layout.
setOnClickListener {
 isSelected =!isSelected
What does the end result of this look like?
contourlayout animation
Context-Aware API
 x = leftTo { name.left() }.leftTo { name.right() },
 y = topTo { name.bottom() }
will not compile.
Axis Type Safety
toLeftOf { }
Circular Reference Debugging
 - name.right aligns to note.left
 - and note.left aligns to name.right
Comparison with Compose
The only similarity between Contour and Compose is that they both realize writing layouts in Kotlin is maximum cool.

Subsymbol Communication
Passing information between symbols is key to getting the most use out of them.
Symbol communication can be broken down into three main subheadings:
 - Accessing controllers
 - Accessing nodes
 - Accessing exported functions and variables
For the purposes of this article, we will use the example of a parent symbol communicating with a subsymbol, though the same is also true of subsymbol-to-subsymbol communication.
Creating an instance of the subsymbol
Before we can proceed we need a variable storing an instance of the subsymbol we want to access within a script node. We'll use this variable to access the information within the subsymbol.
Dragging a subsymbol from the Symbol Definitions Panel into a script and selecting 'Construct symbol' adds code that constructs a new instance of the symbol and assigns it to a variable.
Alternatively, dragging an instance of a subsymbol from the Hierarchy into a script and selecting 'insert local variable' will create a variable referencing the instance created in the Hierarchy.
// constructing from the Symbol Definitions Panel
var mySubsymbolConstructed = symbol.symbolDefinitions.mySubsymbol();
// instance referenced from the Hierarchy
var mySubsymbolInstance = symbol.nodes.mySubsymbol;
Symbols constructed within a script node will not display automatically. For Blank symbols, we recommend adding them to the Hierarchy at runtime using the Z.Group push function. For Screen symbols we recommend using the symbol's display function, for more information see the Screen Symbol article.
Accessing controllers
Accessing the timelines and states of a subsymbol allows us to control the animations from the parent symbol.
In order to activate a state or play a timeline within a subsymbol from the parent symbol, you need to be able to access the controller for that subsymbol.
To access the list of controllers in a subsymbol you use the following syntax:
Adding a further dot will allow you to specify a controller by name:
To access the states and timelines within that controller, which are of the Z.Element type, you use the elements keyword:
From there the individual states and timelines can be accessed:
You can then use the functions of the given state or timeline:
Accessing nodes
You can access the nodes within a subsymbol's Hierarchy using the nodes keyword:
From there the individual nodes can be accessed by name:
You can then use the functions of the node (in this case the Z.Object color function):
Accessing exported functions and variables
Functions and variables can be declared in one script and retrieved in another using the export keyword. The example below uses two script nodes, script1 and script2, within the same symbol.
// script1
export let myVariable;
// script2
The same functionality can be used to access exported variables and functions within subsymbols.
//'myScript' script node within the subsymbol
export let myVariable;
// script node within the parent symbol

Ciudad Rodrigo, Diocese of (CIVITATENSIS), suffragan of the Diocese of Santiago, comprises the greater part of the province of Salamanca, and a portion of the province of Caceres. The city of Ciudad Rodrigo, which is the capital of the diocese, was named for the Count Rodrigo Gonzalez, who founded it about the middle of the twelfth century. It has approximately a population of 7000 inhabitants, and is the head of the judicial district. The bishopric was established by Ferdinand II, King of Leon, its establishment being confirmed by Pope Alexander III in 1175. This see finally succeeded that of Caliabria, which dated from the Visigothic era, and existed from 621 to 693. Alfonso VIII gave the city of Caliabria to the Diocese of Ciudad Rodrigo in 1191. The first bishop of whom anything certain is known was called Pedro (1165); the most celebrated was the learned jurist Don Diego de Covarruvias y Leyva (1560).
