Magnetically impelled arc butt (MIAB) welding is a “single shot” method of joining pipe and tube which is used in highly automated factory production lines in high volume industries such as automotive manufacture. The entire weld over the full joint thickness is made in one single operation, instead of using several passes as in conventional welding. It is believed to be capable of making finished welds in pipe from small diameters of around 75mm (DN75) up to around DN450, and to around 10mm wall thickness. The welding time is around 10 to 15 seconds, and the joint to joint cycle time will be about 1 minute. Under the right circumstances this means that pipelines in this size range could be welded at a rate of up to around 7.5km per day or more, with only a single small welding crew and a substantial reduction in overall cost. Whilst the circumstances that allow construction spreads to take advantage of that potential speed will not exist on every pipeline, there are still major economic and technical advantages to be had from using the process at more moderate rates. The present target thickness limit of 10mm will make it possible to weld Class 900 DN450 pipelines with maximum allowable operating pressures of up to 15 MPa. The use of MIAB welding will enable the entire paradigm of pipeline construction to be changed, and will lead to reductions in construction cost of around 15% or more when the process is first implemented. Larger savings are expected in the longer term.

High-volume hydraulic fracturing combined with horizontal drilling has “revolutionized” the United States’ oil and gas industry by allowing extraction of previously inaccessible oil and gas trapped in shale rock [1]. Although the United States has extracted shale gas in different states for several decades, the United Kingdom is in the early stages of developing its domestic shale gas resources, in the hopes of replicating the United States’ commercial success with the technologies [2, 3]. However, the extraction of shale gas using hydraulic fracturing and horizontal drilling poses potential risks to the environment and natural resources, human health, and communities and local livelihoods. Risks include contamination of water resources, air pollution, and induced seismic activity near shale gas operation sites. This paper examines the regulation of potential induced seismic activity in Oklahoma, USA, and Lancashire, UK, and concludes with recommendations for strengthening these protections.

 AbstractActually the existence of foreign investment in Indonesia is not new phenomenon, due to foreign investment exist since colonialism era.The existence of foreign investment is still continuing to Soeharto era until reformation era. Spirit of foreign investment in colonialism era, Soharto era, and reformation era are different. Foreign investment in colonialsm era just explore of nation asset and ignore of nation welfare, and this matter is different from the character of foreign investment in Soeharto era also reformation era. Eventhough the involvement of foreign investor have any benefits to the host country, but on the other hand foreign investment have business oriented only whether the investment is secure and may result of profit. Refer to The Law Number 25 Year of 2007 Concerning Investment (hereinafter called UUPM) can not be separated from various interest that become of politic background of the law, even the law tend to liberalism of investment. Liberalism in the investment sector particularly of foreign investment basically exist far from issuing of UUPM, and the spirit of liberalism also stipulate in several rules among others The Law Number 5 Year of 1999 Concerning Prohibitation of Anti Trust and Unfair Competition, The Law Number 22 Year of 2001 Concerning Oil and Gas, The Law Number 7 Year of 2004 Concerning Water Resource, and also The Law Number 30 Year of 2009 Concerning Electricity.   Many rules as mentioned above has liberalism character and also indicator opposite wit the right to manage of the state to nation asset that relate to public interest as stipulated in the Indonesia Constitution. Actually the issuing of UUPM in case of implementation of article 33 Indonesia Constitution (UUD NRI 1945). Due to opportunity by Government to foreign investment as stipulate by article 12 UUPM and also the existence of many rules as well as The Law Number 5 Year of 1999 Concerning Prohibitation of Anti Trust and Unfair Competition, The Law Number 22 Year of 2001 Concerning Oil and Gas, The Law Number 7 Year of 2004 Concerning Water Resource, and also The Law Number 30 Year of 2009 Concerning Electricity, so the foreign investment that relate to public service is more exist in Indonesia. The existence is reflected many foreign companies. Free of foreign investment relate to public service is opposite with spirit of article 33 Indonesia Constitution. Keywords: Foreign Investment, Right of  State, Article 33 Indonesia Consitution AbstrakEksistensi penanaman modal asing (investasi asing) di Indonesia sebenarnya bukan merupakan fenomena baru di Indonesia, mengingat modal asing telah hadir di Indonesia sejak zaman kolonial dahulu.   Eksistensi penanaman modal asing terus berlanjut pada era orde baru sampai dengan era reformasi. Tentunya semangat penanaman modal asing pada saat era kolonial, era orde baru, dan era reformasi adalah berbeda. Penanaman modal asing pada saat era kolonial memiliki karakter eksploitatif atas aset bangsa dan mengabaikan kesejahteraan rakyat, hal ini tentunya berbeda dengan karakter penanaman modal asing pada era orde baru, dan era reformasi. Sekalipun kehadiran investor membawa manfaat bagi negara penerima modal, di sisi lain investor yang hendak menanamkan modalnya juga tidak lepas dari orientasi bisnis (oriented business), apakah modal yang diinvestasikan aman dan bisa menghasilkan keuntungan. Melihat eksistensi Undang–Undang Nomor 25 Tahun 2007 tentang Penanaman Modal (UUPM) tidak dapat dilepaskan dari beragam kepentingan yang mendasari untuk diterbitkannya undang–undang tersebut, bahkan terdapat kecenderungan semangat dari UUPM lebih cenderung kepada liberalisasi investasi. Liberalisasi pada sektor investasi khususnya investasi asing pada dasarnya eksis jauh sebelum lahirnya UUPM ternyata juga tampak secara tersirat dalam beberapa peraturan perundang–undangan di Indonesia. Perundang–undangan tersebut antara lain Undang–Undang Nomor 5 Tahun 1999 tentang Larangan Praktek Monopoli dan Persaingan Usaha Tidak Sehat, Undang–Undang Nomor 22 Tahun 2001 tentang Minyak Dan Gas Bumi, Undang–Undang Nomor 7 Tahun 2004 tentang Sumber Daya Air, dan Undang–Undang Nomor 30 Tahun 2009 tentang Ketenagalistrikan.Banyaknya peraturan perundang–undangan yang berkarakter liberal sebagaimana diuraikan di atas mengindikasikan bahwa hak menguasai negara atas aset bangsa yang berkaitan dengan hajat hidup orang banyak sebagaimana diamahkan oleh Undang–Undang Dasar 1945 (Konstitusi) mulai “dikebiri” dengan adanya undang–undang yang tidak selaras semangatnya. Padahal, UUPM diterbitkan dalam kerangka mengimplementasikan amanat Pasal 33 Undang–Undang Dasar Negara Republik Indonesia Tahun 1945 (UUD NRI 1945). Dengan adanya peluang yang diberikan oleh pemerintah kepada investor asing sebagaimana yang diatur dalam Pasal 12 UUPM ditambah lagi dengan adanya Undang–Undang Nomor 5 Tahun 1999 tentang Larangan Praktek Monopoli dan Persaingan Usaha Tidak Sehat, Undang–Undang Nomor 22 Tahun 2001 tentang Minyak Dan Gas Bumi, Undang–Undang Nomor 7 Tahun 2004 tentang Sumber Daya Air, dan Undang–Undang Nomor 30 Tahun 2009 tentang Ketenagalistrikan, maka investasi asing yang berhubungan dengan cabang– cabang yang menguasai hajat hidup orang banyak semakin eksis di Indonesia. Terbukanya investasi asing atas cabang–cabang produksi yang menguasai hajat hidup orang banyak tentunya hal ini bertentangan dengan konsep hak menguasai negara sebagaimana diatur dalam Pasal 33 UUD NRI 1945. Kata Kunci: Investasi Asing, Hak Menguasai Negara, Pasal 33 UUD NRI Tahun          1945

Abstract Background Clinical trials performed in our emergency department at Barnes-Jewish Hospital utilize a centralized infrastructure for alerting, screening, and enrollment with rule-based alerts sent to clinical research coordinators. Previously, all alerts were delivered as text messages via dedicated cellular phones. As the number of ongoing clinical trials increased, the volume of alerts grew to an unmanageable level. Therefore, we have changed our primary notification delivery method to study-specific, shared-task worklists integrated with our pre-existing web-based screening documentation system. Objective To evaluate the effects on screening and recruitment workflow of replacing text-message delivery of clinical trial alerts with study-specific shared-task worklists in a high-volume academic emergency department supporting multiple concurrent clinical trials. Methods We analyzed retrospective data on alerting, screening, and enrollment for 10 active clinical trials pre- and postimplementation of shared-task worklists. Results Notifications signaling the presence of potentially eligible subjects for clinical trials were more likely to result in a screen (p < 0.001) with the implementation of shared-task worklists compared with notifications delivered as text messages for 8/10 clinical trials. The change in workflow did not alter the likelihood of a notification resulting in an enrollment (p = 0.473). The Director of Research reported a substantial reduction in the amount of time spent redirecting clinical research coordinator screening activities. Conclusion Shared-task worklists, with the functionalities we have described, offer a viable alternative to delivery of clinical trial alerts via text message directly to clinical research coordinators recruiting for multiple concurrent clinical trials in a high-volume academic emergency department.

Cost-efficient designs of aluminum autobody structures consist mainly of stampings using conventional technology. Progress in metallurgy and forming processes has enabled aluminum body panels to achieve significant market share, particularly for hoods. Fast bake hardening alloys with better hemming performance were developed for improved outer panel sheet products. Specific guidelines for handling and press working were established to form aluminum panels using similar schedules and production lines as steel parts. Stamping productivity was improved by optimization of the trimming process to reduce sliver/particle generation and resulting end-of-line manual rework. Both hemming formability and trimming quality not only depend on tooling setup but also on microstructural features, which govern intrinsic alloy ductility. Targets for the next high volume aluminum car body applications, such as roof panels and doors, require higher strength and/or better formability. The challenges of complex stampings can be met with optimized alloys and lubricants, with improved numerical simulation to fine-tune stamping process parameters, and with the introduction of new technologies. Warm forming was examined as a potential breakthrough technology for high volume stamping of complex geometries.

1. Selective ablations of the hand representations in postcentral cortical areas 3a, 3b, 1, and 2 were made in different combinations to determine each area's contribution to the responsivity and modality properties of neurons in the hand representation in SII. 2. Ablations that left intact only the postcentral areas that process predominantly cutaneous inputs (i.e., areas 3b and 1) yielded SII recording sites responsive to cutaneous stimulation and none driven exclusively by high-intensity or "deep" stimulation. Conversely, ablations that left intact only the postcentral areas that process predominantly deep receptor inputs (i.e., areas 3a and 2) yielded mostly SII recording sites that responded exclusively to deep stimulation. 3. Ablations that left intact only area 3a or only area 2 yielded substantial and roughly equal reductions in the number of deep receptive fields in SII. By contrast, ablations that left intact only area 3b or only area 1 yielded unequal reductions in the number of cutaneous receptive fields in SII: a small reduction when area 3b alone was intact but a somewhat larger one when only area 1 was intact. 4. Finally, when the hand representation in area 3b was ablated, leaving areas 3a, 1, and 2 fully intact, there was again a substantial reduction in the encounter rate of cutaneous receptive fields. 5. The partial ablations often led to unresponsive sites in the SII hand representation. In SII representations other than of the hand no such unresponsive sites were found and there were no substantial changes in the ratio of cutaneous to deep receptive fields, indicating that the foregoing results were not due to long-lasting postsurgical depression or effects of anesthesia. 6. The findings indicate that modality-specific information is relayed from postcentral cortical areas to SII along parallel channels, with cutaneous inputs transmitted via areas 3b and 1, and deep inputs via areas 3a and 2. Further, area 3b provides the major source of cutaneous input to SII, directly and perhaps also via area 1. 7. The results are in line with accumulating anatomic and electrophysiologic evidence pointing to an evolutionary shift in the organization of the somatosensory system from the general mammalian plan, in which tactile information is processed in parallel in SI and SII, to a new organization in higher primates in which the processing of tactile information proceeds serially from SI to SII. The presumed functional advantages of this evolutionary shift are unknown.

AbstractIn the 20 years that have passed since the Karen Quinlan case exposed a simmering clinical issue to the light of day — more precisely, to the press and to judicial process — a consensus has developed in American law about how end-of-life decisionmaking should occur. To be sure, there are dissenting voices from this consensus, but they are often (though not always) about minor issues. By illustrating how this consensus has evolved, this paper explores how law is made in the American legal system and the roles that different legal and extra-legal institutions play in lawmaking.

The summary judgment procedure in South African law provides for a speedy judgment in favour of a deserving plaintiff where it can be shown that the defendant does not have a triable defence. In 2019 the Rules Board made certain drastic amendments to the procedure of summary judgment in the high court. In this article the historical development of the procedure of summary judgment will be discussed, and the new amendments to rule 32 of the Uniform Rules of Court critically evaluated. It will be argued that the amendments to rule 32 were unnecessary and that it may diminish the right to access to justice in civil disputes. It will, however, also be argued that there are some merits in the critique raised by the Rules Board in relation to rule 32 and that the Rules Board missed a golden opportunity to overhaul the entire summary judgment procedure in a more sensible manner and in line with the core constitutional values of s 34 of the Constitution. It will be argued that rule 32 should be replaced in its entirety by a new, more streamlined procedure, and some recommendations for legal reform will be made in this regard.

Access to water, in sufficient quantities and of sufficient quality is vital for human health. The United Nations Committee on Economic, Social and Cultural Rights (in General Comment 15, drafted 2002) argued that access to water was a condition for the enjoyment of the right to an adequate standard of living, inextricably related to the right to the highest attainable standard of health, and thus a human right. On 28 July 2010 the United Nations General Assembly declared safe and clean drinking water and sanitation a human right essential to the full enjoyment of life and all other human rights. This paper charts the international legal development of the right to water and its relevance to discussions surrounding the growth of unconventional energy and its heavy reliance on water. We consider key data from the country with arguably the most mature and extensive industry, the USA, and highlight the implications for water usage and water rights. We conclude that, given the weight of testimony of local people from our research, along with data from scientific literature, non-governmental organization (NGO) and other policy reports, that the right to water for residents living near fracking sites is likely to be severely curtailed. Even so, from the data presented here, we argue that the major issue regarding water use is the shifting of the resource from society to industry and the demonstrable lack of supply-side price signal that would demand that the industry reduce or stabilize its water demand per unit of energy produced. Thus, in the US context alone, there is considerable evidence that the human right to water will be seriously undermined by the growth of the unconventional oil and gas industry, and given its spread around the globe this could soon become a global human rights issue.

The observations of the late transit of Venus, though made with all possible care and accuracy, have not enabled us to determine with certainty the real quantity of the sun's parallax; since, by a comparison of the observations made in several parts of the globe, the sun's parallax is not less than 8" 1/2, nor does it seem to exceed 10". From the labours of those gentlemen, who have attempted to deduce this quantity from the theory of gravity, it should seem that the earth performs its annual revolution round the sun at a greater distance than is generally imagined: since Mr. Professor Stewart has determined the sun's parallax to be only 6', 9, and Mr. Mayer, the late celebrated Professor at Gottingen, who hath brought the lunar tables to a degree of perfection almost unexpected, is of opinion that it cannot exceed 8".
