Abstract Currently, the use of organic materials as organic fertilizer has been widely used by farmers. The awareness of farmers to use organic fertilizers has made organic fertilizers increasingly difficult to obtain. Organic fertilizers from chicken, goat and cow farms have generally been ordered and purchased by certain farmers. Therefore, alternative uses of other organic fertilizers need attention. Lowland peat is quite widely available in Indonesia, especially in North Sumatra. Peatlands are spread from the east coast of Aceh Province to the east coast of the Riau Province border. This potential makes it possible for peat to be modified into alternative organic fertilizers. One of the disadvantages of organic fertilizers is the large volume and weight. To overcome this problem, peat is made into briquettes through a pressing process so that its volume can be reduced to 1/3 times its previous volume. In addition, the acidic nature of peat is also expected to be greatly reduced by wasting peat water content. After being made into briquettes, the briquettes are used as organic fertilizer treatment for planting macadamia plants in the field. The results showed that the provision of briquettes from peat could increase the growth of macadamia plants compared to control. However, giving briquettes at a dose of 0.5 kg was not significantly different from giving briquettes up to 1.5 kg.

The Anatomy Quizbook Volume 2 contains questions and answers pertinent to the head and neck, vertebral column, and upper and lower limbs. Built on a series of carefully selected questions, AQV2 addresses core learning in clinically relevant anatomy, and provides the opportunity for both pre-med and medical students to improve their knowledge of anatomy, as well as their performance in tests and examinations. This form of self-testing has many benefits: it is proven to aid retention, it is a useful method to apply at regular intervals to ensure robust knowledge, and it is extremely useful to determine what is known before rather than after a test or exam. The previous volume (Anatomy Quizbook Volume 1) contains questions and answers applicable to anatomical terms and the thorax, abdomen and pelvis.

BackgroundThis cadaveric study investigated the maximum effective volume of dye in 90% of cases (MEV90), required to stain the suprascapular nerve while sparing the phrenic nerve during the performance of an anterior suprascapular nerve block.MethodsIn cadaveric neck specimens, using ultrasound guidance, the block needle was advanced until its tip was positioned underneath the omohyoid muscle next to the suprascapular nerve. The dye was injected in order to achieve circumferential spread around the latter. Successful phrenic-sparing suprascapular nerve block was defined as the non-staining of the phrenic nerve on dissection. Volume assignment was carried out using a Biased Coin Design, whereby the volume of dye administered to each cadaveric specimen depended on the response of the previous one. In case of failure (ie, stained phrenic nerve), the next one received a lower volume (defined as the previous volume with a decrement of 2 mL). If the previous cadaveric specimen had a successful block (ie, non-stained phrenic nerve), the next one was randomized to a higher volume (defined as the previous volume with an increment of 2 mL), with a probability of b=0.11, or the same volume, with a probability of 1 – b=0.89.ResultsThirty-one cadavers (56 cadaveric neck specimens) were included in the study. Using isotonic regression and bootstrap CI, the MEV90 for phrenic-sparing anterior suprascapular nerve block was estimated to be 4.2 mL (95% CI 3.0 to 5.0 mL). The probability of a successful response was estimated to be 0.90 (95% CI 0.84 to 0.96).ConclusionFor ultrasound-guided anterior suprascapular nerve block, the MEV90 of dye required to spare the phrenic nerve is 4.2 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in live subjects.

BackgroundThis cadaveric dose-finding study investigated the minimum effective volume of dye in 90% of cases (MEV90), required to stain the femoral, lateral femoral cutaneous and obturator nerves for ultrasound-guided suprainguinal fascia iliaca block (SIFIB).MethodsIn cadaveric specimens of the lower limb, the block needle was advanced, medial to the anterosuperior iliac spine, until its tip was positioned between the internal oblique and iliacus muscles underneath the fascia iliaca. The dye was injected inside the fascia iliaca compartment. Volume assignment was carried out using a biased coin design, whereby the volume of dye administered to each cadaveric specimen depended on the response of the previous one. In case of failure, the next one received a higher volume (defined as the previous volume with an increment of 2.5 mL). If the previous cadaveric specimen had a successful block, the next one was randomized to a lower volume (defined as the previous volume with a decrement of 2.5 mL), with a probability of b=0.11, or the same volume, with a probability of 1–b=0.89. Success was defined as the staining of the femoral, lateral femoral cutaneous, and obturator nerves on dissection.ResultsThirty-six cadavers (60 cadaveric specimens) were included in the study. Using isotonic regression and bootstrap CI, the MEV90 for ultrasound-guided SIFIB was estimated to be 62.5 mL (95% CI 60 to 65).ConclusionFor ultrasound-guided SIFIB, the MEV90 of dye required to stain the femoral, lateral femoral cutaneous and obturator nerves is 62.5 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in human subjects.

This article responds to the innovative and stimulating research by Ellen van Wolde in a previous volume of Journal for the Study of the Old Testament. She claims that the Niphal is middle voice and can be passive, ‘if (and only if) an external argument, coded as an external Agent, is present’. My research however, demonstrates that such a description of the passive is both inadequate in view of the world’s languages and incongruent with Niphal. In addition, my response lays bare how such a prescription of the middle voice to the Niphal in the Hebrew Bible is circulus probando and unconvincing.

Since this book is a sequel to Commonplace Learning, it begins with a synopsis of the previous volume. Ramism before 1620 was most deeply rooted in the fragmented political and confessional geography of the northwestern corner of the Holy Roman Empire. Its function was to provide small polities with the means to transmit the maximum amount of useful learning with a minimum of time, effort, and expense. The appeal of this pedagogy to magistrates, rulers, parents, and students generated a motive force capable of spreading Ramism horizontally from one gymnasium to another and then vertically through gymnasia illustria to full universities, even in the face of opposition by humanists and theologians. Student demand then forced the universities to adapt begin expounding traditional Aristotelian philosophical substance in quasi-Ramist pedagogical form. Once Bartholomäus Keckermann (c. 1572–1608) had emancipated philosophical instruction from the text of Aristotle in this way, bolder men like the young Johann Heinrich Alsted (1588–1638) began using Keckermann’s systematic method to assemble increasingly eclectic doctrinal mixtures. The stage was set to deploy similar pedagogical methods to ease the assimilation of the bold new philosophies of the era of Descartes into university instruction as well. But before that happened, however, the outbreak of the Thirty Years War destroyed the network of German Reformed educational institutions which had sustained this tradition and scattered its students and teachers in all directions. The Reformation of Common Learning narrates some of the consequences of that diaspora for the intellectual history of the mid-seventeenth century.

"According to Alfred Cortot, the suite Le tombeau de Couperin could be divided into two main units. The first part presented in the previous volume of this journal, analyses the structural arch of the suite: the first two and the last part, which uses specific compositional technics of the Baroque era. This second part presents the middle section of the suite, the reminiscence of baroque dance forms, through the three contrasting dances: Forlane, Rigaudon, and Menuet. The fusion between the elements of the French baroque keyboard music and the characteristics of the modern piano music transforms this suite into a real and unique masterpiece. By analyzing the Forlane, the Rigaudon, and the Menuet of the suite we can understand the view of twentieth-century artists on the music of the Baroque era. Keywords: Ravel, Suite, Baroque, Reminiscence, Baroque dance forms, Piano, Forlane, Rigaudon, Menuet"

This article, written by the coordinators of the Stitching Together network, introduces a diverse range of case studies that critically discuss participatory textile making activities, complementing a first collection of case studies that was provided in the previous volume of this journal. Drawing on a recent network event and the case studies included in this issue, the article outlines a number of ethical dimensions that arise in participatory textile making activities: first, the challenge of inclusivity; second, the vulnerabilities that arise when space is made for shared learning; third, the issue of communication between facilitators, participants and partners in collaborative projects; and fourth, the ways in which projects and participants are (re)presented in research findings. The theme of innovation is also discussed, with a focus on the participant experience. Looking to the future, the need for further collaborative interrogation of the complex questions raised through participatory textile work is highlighted. A good practice document, created with the input of network members, is highlighted as a potentially useful foundation for continued critical discussion.

The naming of Dandelion Crater as a lunar navigation point by the Apollo 15 crew establishes the baseline for assessing Bradbury’s continuing role as a Space Age visionary and talisman. The chapter offers deeper context through a brief summary of his earlier rise to Space Program prominence as described in the previous volume, Ray Bradbury Unbound. As the Apollo program came to an end, Bradbury began work designing the basic ride concept and narrative for what would become Spaceship Earth at Disney World’s EPCOT. Chapter 1 closes with the termination of Apollo, long-term setbacks in Disney’s Spaceship Earth planning efforts, and the effect of these twin disappointments on Bradbury.

AbstractOn May 1, 2019, the significant impediment to effective competition (“SIEC”) test pursuant to Article 2(2) and (3) of the EU Merger Regulation (Regulation No. 139/2004; “EUMR”), celebrated its 15th anniversary. The Commission has taken more than 5,000 decisions in merger cases under this new standard in the last decade and a half. Therefore, it seems opportune to pause and take stock. Has the introduction of the SIEC test achieved the desired results? Has it been applied according to the legislator’s plans? Does its application need to change going forward?After a short recap of the test’s history and genesis (I.) and a reminder of the burden and standard of proof (II.), this article reviews the Commission’s decisional practice (and the limited practice of the EU Courts) systematically, and intends to summarize the various theories of harm covered by the SIEC test’s application in practice (III.). Second, it analyzes the decisional practice and draws conclusions as to whether the test’s application in practice is predictable, persuasive, and in line with the legislator’s intent (IV.). Third and last, after some practical and procedural observations (V.), it concludes with a few proposals for improvement (VI.).Given the scope of the ground covered, this article is split into two separate parts over two separate volumes of this journal, with Part 1 in the journal’s previous volume having covered sections I. and II., as well as part III. with respect to horizontal mergers and a brief summary in this respect.This Part 2 of the article continues in this volume in section III. with non-horizontal mergers, and finishes with sections IV. through VI.
