Over the years, many issues have confronted the industry, and affected its approach to business. A brief analysis of seismic and exploration drilling levels over the past four decades demonstrates how marked these effects have been. During 1999, fewer wells have been drilled onshore in Australia than for any year since 1979. This is due in large part to the refusal of some State Governments to award newly gazetted acreage due to native title concerns. The solution required is a legislative one. Offshore drilling, however, is at a historically high level, and during 1999, had a success rate of one in five. Successes in both the onshore and offshore were restricted to currently producing basins.

Liberal Government

In 2020, the Federal Morrison Liberal Government scrambled to respond to the effects of the international coronavirus pandemic on the Australian labour market in two key ways. First, through largescale social welfare and economic stimulus (the ‘JobKeeper’ scheme) and second, through significant proposed reform to employment laws as part of a pandemic recovery package (the ‘Omnibus Bill’). Where the first measure was administered by employers, the second was largely designed to suspend and/or redefine labour protections in the interests of employers. In this respect, the message from the Federal Government was clear: that the costs of pandemic recovery should be borne by workers at the discretion of employers. State Labor Governments, by contrast, enacted a range of industrial protections. These included the first Australia ‘wage theft’ or underpayment frameworks on behalf of both employees and contractors in the construction industry. On-trend with state industrial legislation over the past 4 years, these state governments continued to introduce industrial manslaughter offences, increased access to workers’ compensation, labour hire licensing schemes and portable long service leave.

Revolutionary Science

The explosion of online knowledge has made knowledge, paradoxically, difficult to find. A web or journal search might retrieve thousands of articles, ranked in a manner that is biased by, for example, popularity or eigenvalue centrality rather than by informed relevance to the complex query. With hundreds of thousands of articles published each year, the dense, tangled thicket of knowledge grows even more entwined. Although natural language processing and new methods of generating knowledge graphs can extract increasingly high-level interpretations from research articles, the results are inevitably biased toward recent, popular, and/or prestigious sources. This is a result of the inherent nature of human social-learning processes. To preserve and even rediscover lost scientific ideas, we employ the theory that scientific progress is punctuated by means of inspired, revolutionary ideas at the origin of new paradigms. Using a brief case example, we suggest how phylogenetic inference might be used to rediscover potentially useful lost discoveries, as a way in which machines could help drive revolutionary science.

In many complex systems one observes the formation of medium-level structures, whose detection could allow a high-level description of the dynamical organization of the system itself, and thus to its better understanding. We have developed in the past a powerful method to achieve this goal, which however requires a heavy computational cost in several real-world cases. In this work we introduce a modified version of our approach, which reduces the computational burden. The design of the new algorithm allowed the realization of an original suite of methods able to work simultaneously at the micro level (that of the binary relationships of the single variables) and at meso level (the identification of dynamically relevant groups). We apply this suite to a particularly relevant case, in which we look for the dynamic organization of a gene regulatory network when it is subject to knock-outs. The approach combines information theory, graph analysis, and an iterated sieving algorithm in order to describe rather complex situations. Its application allowed to derive some general observations on the dynamical organization of gene regulatory networks, and to observe interesting characteristics in an experimental case.

Abstract: Regarding the society evolution dominated by a high-level technology, we consider this article a constructive approach. The aim of the paper is to highlight a few activities/places/spots in which competences of humans/soldiers interfere with different elements of the artificial intelligence. We deem that the technological progress in the past few years has been impressive. Nowadays, thousands of activities that were mostly or exclusively executed by people can be done faster and often with greater precision using digital systems. In this instance and considering the achievement of functional compatibility between Romanian Army and forces from NATO as being a priority, the development of the technology based on artificial intelligence is vital within the defense resource management.

Заболеваемость раком яичников в России в последнее время остается на высоком уровне. В мире более ста тысяч женщин умирают вследствие протекания данного заболевания. За последнее десятилетие заболеваемость острым эндометритом также неуклонно возрастает. Острый эндометрит обладает полиморфизмом симптомов, лабораторных и ультразвуковых изменений и вследствие этого тяжело поддается диагностике и дифференциальной диагностике. В условиях стационара обследованы 100 пациенток с раком яичников II-III стадии и 90 пациенток с диагнозом острого эндометрита. Им выполнялось ультразвуковое исследование. Полученные результаты подвергались обработке и математико-статистическому анализу, включающему расчёт показателей дезинтеграции, сетевое моделирование, математическое ранжирование. Изучение ультразвуковых изменений кровотока в маточных и яичниковых сосудах и венах у 100 заболевших раком яичников и 90 заболевших острым эндометритом дал возможность выделить ведущие дифференциально-диагностические аспекты. Характеристики дезинтеграции, в одном ряду со средними значениями локального кровотока, объективизируют дифференциацию рака яичников и острого эндометрита. В согласовании с дифференциально-диагностической значимостью ультразвуковых характеристик артериального кровотока в маточных и яичниковых сосудах построена сетевая модель дифференциальной диагностики рака яичников и острого эндометрита по более приоритетным переменам, собственно, что разрешает уменьшить размер и время обследования пациента и постановки верного диагноза The incidence of ovarian cancer in Russia has recently remained at a high level. In the world, more than a hundred thousand women die as a result of the course of this disease. The incidence of acute endometritis has also been steadily increasing over the past decade. Acute endometritis has a polymorphism of symptoms, laboratory and ultrasound changes and, as a result, is difficult to diagnose and differential diagnosis. 100 patients with stage II-III ovarian cancer and 90 patients with acute endometritis were examined in the hospital. They performed an ultrasound examination. The obtained results were processed and subjected to mathematical and statistical analysis, including the calculation of disintegration indicators, network modeling, and mathematical ranking. The study of ultrasound changes in blood flow in the uterine and ovarian vessels and veins in 100 patients with ovarian cancer and 90 patients with acute endometritis made it possible to identify the leading differential diagnostic aspects. The characteristics of disintegration, along with the average values of local blood flow, objectify the differentiation of ovarian cancer and acute endometritis. In accordance with the differential diagnostic significance of the ultrasound characteristics of arterial blood flow in the uterine and ovarian vessels, a network model for the differential diagnosis of ovarian cancer and acute endometritis is constructed according to higher priority changes, which actually allows reducing the size and time of the patient's examination and making the correct diagnosis

Early Music Revival

The early-music revival provoked much heated debate in the second half of the nineteenth century. The leading scholars of the era, Philipp Spitta and Friedrich Chrysander were keen to encourage performances and editions of early music that presented it in the spirit in which it was conceived. This approach met with vociferous opposition from Robert Franz and his supporters, who embraced a Darwinian aesthetic. Although committed to reviving the past, Franz believed that the tastes of nineteenth-century listeners had become too sophisticated to enjoy early music in its original state and modernized it accordingly. The source of the most heated debates was the issue of continuo realization, a topic in which Brahms, through his performing and arranging activities, had a vested interest. Franz, who dismissed the musicologists as artistic philistines, found a difficult adversary in Brahms. Brahms's scholarly inclinations have been well documented, and predictably, his approach to reviving Baroque music reflected a high level of historical awareness. He was, however, first and foremost a creative musician, and as a consequence, aesthetic issues were paramount in his performances and publications. Considerable tensions arose between Franz, and Brahms, and Chrysander, which are explored here in relation to the latter's editions of Handel's Italian duets and trios. The difficulties surrounding continuo practice were not confined to opposition from Franz; even among musicologists there was much disagreement about how the music should be performed. Brahms's approach to continuo realization is considered in this context.

The author summarizes the most important data about the development of reconstructive techniques of nerve injuries in the hand based on literature references and the author’s own experience in the past decades. A new bulk of knowledge turned into a common property related to the micro- and macroanatomic structure of peripheral nerves, the process of nerve regeneration, and the technical conditions of nerve reconstructive operations. This knowledge is a prerequisite for hand surgeons to perform their nerve reconstructive operations on a contemporary high level with an optimal result. After a critical review of literature data, the author reports his own experience and sketches the coming possible roads. A detailed list of references is also provided for those who are interested in the field. Orv. Hetil., 2012, 153, 1767–1778.

The past earthquake records in North Lombok show the high level of earthquake hazard in this area. The maximum magnitude of the earthquake was 6.4 Mw on May 30th, 1979. But, there were no tsunami events records due to those earthquakes. Nevertheless, this area is very close to Mataram City (province capital city) and tourism area. Therefore, the assessment of tsunami hazard is very important. The tsunami simulation was conducted by using COMCOT Model, which is based on the North Lombok Earthquake as the initial condition. The simulation result shows the prediction of tsunami travel time is about 18 ~ 20 minutes from the source location to Mataram City. The height of the tsunami wave is 0.13 ~ 0.20 meters due to the earthquake magnitude is about 6 Mw.
