Two examples of intentionally perforated ostrich eggshells from the Howiesons Poort. A shows diverging grooves starting at the edge of the perforation. The aperture diameter is estimated to be 12 mm. B shows percussion marks characteristic of a punching technique. In both cases, the perforation is funnel-shaped with an internal diameter greater than the exterior diameter, suggesting a final percussive blow. Conclusion Engraved abstract patterns are widely accepted as evidence for the presence of symbolic thought 1 —

The CNPs were amorphous in nature; the particles were spherical having sizes in the range of 4—30 nm, depending upon the source of extraction. The results also indicated that particles formed at higher temperature were smaller than those formed at lower temperature.
Excitation tuneable photoluminescence was observed for all the samples with quantum yield QY 1.

The Opalite mercury mining district encompasses locations that are both in the state of northern Nevada and in the state of southern Oregon. The deposits are all related to a large volcanic center caldera complex called the McDermitt caldera complex. Mines in the Opalite district include those listed below   . Bretz Mine, Malheur Co. These were both underground and open cut operations. In the s, mercury was discovered in tuffaceous lake sediments adjacent to and just north of the Cordero mine.
This deposit was exploited exclusively by open cut mining. The McDermitt mine was the last operating primary mercury production mine in the USA when it ceased operations in The patented mining claims of the McDermitt mine were still owned by Barrick Gold as of March , but the mine is closed and there is no mining activity in the district. The following summary prepared by Michael Cox is drawn from the extensive body of references and more than five weeks of detailed field examination of the pit during the period of late to early
The proportions of kiln and flue capacity require careful adjustment, for the best advantage can be derived only when they are symmetrical in their measures. Thus it would be unprofitable, and, indeed, inconvenient, were too much kiln-room provided, and thereby require its being lighted when only partially filled. Again, too much flue-space, which would produce more dried slip or slurry than the kiln would contain, would also be a disadvantage Note A

Optima DV Principle: It is an analytical technique useful for the detection of trace elements. When plasma energy is given to an analysis sample from outside, the component elements atoms are excited. When the excited atoms return to low energy position, emission rays spectrum rays are released and the emission rays that correspond to the photon wavelength are measured. ICP-OES include the determination of metals in water samples, arsenic in food, and trace elements bound to proteins.
ICP-AES is often used for analysis of trace elements in soil, and it is for that reason it is often used in forensics to ascertain the origin of soil samples found at crime scenes or on victims etc. Ion Chromatography is a process that allows the separation of ions and polar molecules based on their affinity to the ion exchanger.
Exchange of ions is the basic principle in this type of Chromatography. In this process two types of exchangers i. It is also useful for the determination of some transition elements and organic acids in environmental water samples.

This should include setting out the levels and types of affordable housing provision required, along with other infrastructure such as that needed for education, health, transport, green and digital infrastructure. Such policies should not make development unviable, and should be supported by evidence to demonstrate this. The revised Framework which was published on 24th July has been revised to state at paragraph Viability has moved from a standalone matter to a key consideration within planning decisions in both policy and development management.
This significant shift now requires viability to be dealt with at the plan making stage, thus shifting responsibility on LPAs as opposed to developers. Essentially, LPAs will now be required to set strategic site allocations, infrastructure requirements and a minimum level of affordable housing which they consider viable.
Viability in short is the difference between the price paid for a site compared to the costs of building a development. A development scheme is only viable if, after taking into account all development costs into account including site value, the scheme provides a competitive return so that a scheme can be implemented and the land value is sufficient to incentivise a landowner to sell.
Value of land Return to Developer 1. Land Value The starting point to assessing viability is to establish the benchmark land value.

The intricate work on a Malabar Hookah. Gaddi village men with hookah, on mountain path near Dharamshala , India. The concept of hookah is thought to have originated In India, by Irfan Shaikh, a physician to Mughal emperor Akbar    once the province of the wealthy, it was tremendously popular especially during Mughal rule. The use of hookahs from ancient times in India was not only a custom, but a matter of prestige.
Rich and landed classes would smoke hookahs. Tobacco is smoked in hookahs in many villages as per traditional customs. Smoking tobacco-molasses is now becoming popular among the youth in India. Hookah was recently banned in Bangalore. However, it can be bought or rented for personal usage or organized parties. These are known as Malabar Hookhas or Koyilandy Hookahs.

In accountancy, depreciation refers to two aspects of the same concept: Businesses depreciate long-term assets for both tax and accounting purposes. The former affects the balance sheet of a business or entity, and the latter affects the net income that they report. Generally the cost is allocated, as depreciation expense, among the periods in which the asset is expected to be used. This expense is recognized by businesses for financial reporting and tax purposes.
Methods of computing depreciation, and the periods over which assets are depreciated, may vary between asset types within the same business and may vary for tax purposes.
In the Indian subcontinent, the word huqqa is used (Devanagari: हुक़्क़ा, Eastern Nagari: হুক্কা, Nastaleeq: حقّہ); this word is the origin of the English word “hookah”. The widespread use of the Indian word “hookah” in the English language is a result of the colonization in British India (–), when large numbers of expatriate Britons first sampled the.
The largest study to date, Cook et al. While only 64 papers 0. A later analysis by Legates et al. The second part of Cook et al. Every major scientific organization disagrees with the list. This is misleading since only a very small minority of scientists have actually expressed a position on AGW from these organizations. Policy statements release by a handful of council members or signed by just the president of a scientific organization can speak for no one other than these few scientists.
It is disingenuous to imply that the membership bodies in some cases hundreds of thousands of members of these scientific organizations which have never voted to approve such statements can be used in support of them. Many members join scientific organizations for free access to organizational resources or discounts on journals and meetings. They may have little to no interest in the organization’s policy positions.
Without a comprehensive survey or poll of every member’s position in relation to these organization’s policy statements no meaningful conclusions can be drawn.
