Multicriteria analysis of sustainable development indicators in the construction minerals industry in China
Mining and minerals is an important industry in China. Construction projects, in particular, are on the rise in Beijing. The construction minerals sector has already started responding to sustainability challenges, as demonstrated by the construction group. Thus, construction minerals are important in city development. The aim of this study was to develop a set of measurement and proposed hybri...


Who is the rightful recipient of mining compensation for land use deprivation in Ghana?
Compensation remains a crucial precondition for the compulsory acquisition of land in many jurisdictions across the world. The compensation regime of Ghana is still characterised by uncertainties with the legislative environment. This paper focused on the determination of rightful recipients of compensation for deprivation of use introduced by the new Minerals and Mining Act, 2006 (Act 703) in ...
A Novel Percutaneous Guide Wire (S-Wire) for Percutaneous Pedicle Screw Insertion: Its Development, Efficacy, and Safety
Minimally invasive spine stabilization (MISt) procedures, including MIS–transforaminal lumbar interbody fusion (MIS-TLIF), rely on precise placement of percutaneous pedicle screws (PPS). Serious intraoperative complications associated with PPS placement include great vessel and bowel injuries due to the guide-wire’s anterior migration and penetration through the anterior aspect of t...


Vaginal Access Minimally Invasive Surgery (VAMIS): A New Approach to Hysterectomy
Vaginal hysterectomy is the original natural orifice operation. Although one of the most common gynecologic operations performed, the surgical approach has not changed significantly during the past century. This article describes a new approach to hysterectomy using vaginal access minimally invasive surgery (VAMIS). VAMIS hysterectomy is successfully performed on a cadaveric model. The step-by-...
A Promising New Device for the Prevention of Parastomal Hernia
Parastomal hernia (PSH) is the most frequent long-term stoma complication with serious negative effects on quality of life. Surgical revision is often required and has a substantial morbidity and recurrence rate. The development of PSH requires revisional surgery with a substantial perioperative morbidity and high failure rate in the long-term follow-up. Prophylactic parastomal mesh insertion d...


Exploring Green Streets and rain gardens as instances of small scale nature and environmental learning tools
Sustainable stormwater management facilities such as bioswales and rain gardens are one way in which cities are simultaneously addressing the need to replace or repair stormwater infrastructure while also meeting regulatory obligations. Retrofitting patterns of neighborhood development through the implementation of infrastructure like bioswales is localized solution to stormwater management. Su...
Dynamics of universal computation and 1/f noise in elementary cellular automata
Elementary (one-dimensional two-state three-neighbor) cellular automaton rule 110 is capable of supporting universal computation and exhibits 1 / f noise. However, the power spectra of rule 110 do not always exhibit 1 / f -type spectrum because of periodic background particular to rule 110. Since periodic background in rule 110 does not play any role in supporting universal computation, ...

Worst case complexity of direct search under convexity
In this paper we prove that the broad class of direct-search methods of directional type, based on imposing sufficient decrease to accept new iterates, exhibits the same worst case complexity bound and global rate of the gradient method for the unconstrained minimization of a convex and smooth function. More precisely, it will be shown that the number of iterations needed to reduce the norm of ...
New analysis and results for the Frank–Wolfe method
We present new results for the Frank–Wolfe method (also known as the conditional gradient method). We derive computational guarantees for arbitrary step-size sequences, which are then applied to various step-size rules, including simple averaging and constant step-sizes. We also develop step-size rules and computational guarantees that depend naturally on the warm-start quality of the initial...

Automatic machine translation error identification
Although machine translation (MT) has been an object of study for decades now, the texts generated by the state-of-the-art MT systems still present several errors for many language pairs. ing at coping with this drawback, lots of efforts have been made to post-edit those errors either manually or automatically. Manual post-editing is more accurate but can be prohibitive when too many changes ha...
Spectrochemical Characterization of Red Pigments Used in Classic Period Maya Funerary Practices
We studied the composition, colour chromaticity and form of application of red pigments in human bone samples from seven Classic period Lowland Maya sites. The samples were analysed by X-ray diffraction, scanning electron microscopy (SEM) and X-ray energy-dispersive spectroscopy (EDS). Colour was measured using conventional colour identification standards (Munsell) and reflectance spectroscopy....

A New Method For Combining Lead Isotope and Lead Abundance Data to Characterize Archaeological Copper Alloys
We present a new methodology for interpreting lead isotope data from archaeological copper alloy objects. It is not based on the conventional isotope ratio biplots, which were originally devised to allow the calculation of the geological age of the lead mineralization, but is derived from isotope mixing models, more often used for presenting strontium isotope data. We illustrate the method by r...
Early Renaissance Production Recipes for Naples Yellow Pigment: A Mineralogical and Lead Isotope Study of Italian Majolica from Montelupo (Florence)
The Naples Yellow pigment was apparently used for the first time by the Egyptians, as a glass-colouring agent. Also known in the Mesopotamian and Roman cultures, the recipe was lost in Western Europe between the fourth and the 16th centuries ad. The recipe for the production of lead antimonate recently discovered in the ‘Codice Calabranci’ (second half of the 15th century) at Montelupo, a s...
For Whom the Bells Fall: Metals from the Cenote Sagrado, Chichén Itzá
Bells of copper and copper alloys and gold–copper alloys were deposited in events at the Cenote Sagrado at Chichén Itzá, Mexico during the site's primary occupation (ad 750–1050) and in later centuries. Housed in three museums in the United States and Mexico, bells (n = 38) were evaluated for traces of fabrication and alteration using Vis–UV–IR optical microscopy. Bulk composition...
Elemental Characterization by EDXRF of Imperial Longquan Celadon Porcelain Excavated from Fengdongyan Kiln, Dayao County
A mass of Longquan porcelain shards carved with ‘Guan’ or the dragon patterns were unearthed in the early Ming Dynasty layer of the Fengdongyan kiln site at Dayao County. These celadon shards were fired in the Hongwu and Yongle eras of the Ming Dynasty. In order to research the raw materials and firing technology of the imperial porcelain, 85 typical shards were analysed by energy-dispersiv...
