Abstract
Defoliating insects damage forest plantations, but the estimation of their losses does not take into account wood quality changes. The objective was to evaluate the wood quality and pulp production of two clones of Eucalyptus grandis × Eucalyptus urophylla (clone A) and Eucalyptus saligna (clone B) damaged or not by defoliating insects. Five healthy trees and five attacked by Gonipterus platensis Marelli (Coleoptera: Curculionidae) were selected per clone. The wood volume per hectare in the affected settlements was at least 9% lower and damaged trees showed lower wood basic density, with at least 4.6%. The lignin and extractive content in the wood increased by at least 5.6 and 45%, respectively, while the syringyl/guaiacyl (S/G) ratio remained constant for clone A and increased 10% for clone B. For pulps, an increased effective alkali and decreased pulp yield were experienced for both clones while bleaching or pulp quality was not affected. In the stands affected by defoliating insects, productivity was 9 and 19% lower considering the wood volume per hectare and 15 and 24% considering the cellulose pulp production per hectare, respectively.
Possible therapeutic effect of magnesium in ocular diseases
Authors: Ajith Thekkuttuparambil A. 
Published: November 2019

Abstract
Magnesium (Mg2+) is one of the major elements required to maintain normal metabolism and ionic balances in ocular tissues. The physiological role of Mg2+ is mediated through maintaining the Na+-K+-ATPase on membrane, favoring energy-generating reactions, replication of DNA and protein synthesis. Despite the wide availability of this element, hypomagnesemia has been associated with many human ailments. Recent studies highlighted the association of hypomagnesemia and, thereby, supplementation of Mg2+ in the management of eye diseases. Glaucoma, senile cataract and diabetic retinopathy were associated with low level of extracellular Mg2+. The neurovascular protective effects of Mg2+ mediated through activation of endothelial nitric oxide synthase and inhibition of endothelin-1 eventually result in vasodilatation of retinal vessels. Mg2+ can maintain the lens sodium pump activity and antioxidant status and block the calcium channels and release of glutamate in nerve endings. Furthermore, it can prevent the apoptosis of retinal ganglion cells. All these effects contribute to its being a pharmacological agent against ocular diseases. However, clinical trials are scant. This article discusses the role of Mg2+ as a possible therapeutic agent in the management of glaucoma, cataract and diabetic retinopathy.

Abstract

Background
Cesarean delivery (CD) in primiparas with a term singleton vertex fetus (PTSV) is a sentinel event for the future mode of delivery and determinant of repeat CD risk. We aimed to evaluate the risk factors for primary CD in a population with a decade of sustained low rate of intrapartum CD.

Methods
This was a retrospective single-center cohort study between 2005 and 2014. The primary outcome of the study was the mode of delivery. PTSV who attempted vaginal delivery were identified and categorized according to the mode of delivery: vaginal delivery vs. CD. Risk factors for intrapartum CD adjusted odds ratio (aOR) [95% confidence interval (CI)] in multivariate analysis were reported.

Results
During the study, 121,483 deliveries were registered; 26,301 (21.6%) PTSV were admitted in labor, of which 1944 (7.4%) had an intrapartum CD. Significantly in multivariate analysis, this group had a unique risk profile as compared to those who delivered vaginally; non modifiable risks included advanced maternal age: 3.06 (2.16–4.33), P < 0.001; prior multiple (≥3) miscarriages: 1.94 (1.04–3.62), P = 0.04; low (<6) modified admission cervical score: 2.41 (2.07–2.82), P < 0.001; low birth weight (BW): 1.42 (1.00–2.01), P = 0.05 or macrosomia: 2.38 (1.77–3.21), P < 0.001; modifiable risks included induction of labor: 1.79 (1.51–2.13), P < 0.001 and oxytocin labor augmentation: 8.36 (6.84–10.22), P < 0.001.

Conclusion
In a population of PTSV with a sustained low risk for intrapartum cesarean maintained by a strict labor management, induction of labor remains a significant and sole potentially modifiable risk factor for CD.
To Be(come) Love Itself: Charity as Acquired Originality
Authors: Green Deidre Nicole 
Published: November 2019

Abstract
In 1849, Kierkegaard published The Lily in the Field and the Bird of the Air: Three Devotional Discourses, which were closely followed by two discourses on the woman who was a sinner, published in 1849 and 1850. I argue that these discourses are intended to set the stage to learn how to embody Christian love from the woman. Kierkegaard’s claims about what is required to teach Christian virtue imply that the woman becomes more than loving, she becomes love. I explore his notion of acquired originality and how applied philosophical concepts such as automaticity and skillful coping elucidate this notion.
Pseudonyms? What Pseudonyms? There were no Pseudonyms…
Authors: Pattison George 
Published: November 2019

Abstract
The paper argues that the question of Kierkegaard’s pseudonyms has been largely misconceived. Referencing comparable devices such as anonymity, noms de plume, and heteronyms, and drawing on Heidegger’s discussion of Kierkegaardian pseudonymity in the lectures on Parmenides, the paper further distinguishes between fictional characters (e. g. the Seducer and Assessor Vilhelm), noms de plume (H.H.), fictional editors, and pseudonyms proper. It is argued that in the first authorship only Constantin Constantius and Johannes Climacus approximate to the criteria Kierkegaard himself lays down for pseudonymity. Furthermore, Kierkegaard’s anxieties regarding the form of publication of his works in the late 1840s reveals the whole project of pseudonymity collapsing into incoherence. By means of a comparison with Nietzsche, it is argued that Kierkegaard’s work is less a manifold of different literary personalities and more a play of revealing/concealing voices. In these voices there is nevertheless a literary watermark that makes Kierkegaard’s work as a whole distinctively Kierkegaardian.

Merkreime und Lehrgedichte in frühneuzeitlichen Rechenbüchern
Authors: Schuppener Georg 
Published: November 2019

Abstract
The essay examines the occurrence of rhyming mnemonic devices and doctrinal poems in Early Modern German mathematical textbooks. These works were dedicated to the teaching of basic mathematical knowledge for prospective merchants. The article presents an exemplary selection of mnemonic rhymes and doctrinal poems and discusses their function for the teaching of mathematics. The author emphasizes that rhymed passages can occur in almost all areas (algebra, geometry, etc.) of those textbooks. Mnemonic rhymes and doctrinal poems are used in the works primarily to convey the content in a more memorable fashion and to deformalize the presentation of content. The latter is especially true for rhyming in the field of entertainment mathematics, which is also often a feature of the textbooks. However, by using practically oriented language in instruction, the artistic potential of the rhymes is significantly reduced.

Pengukuran secara langsung sangat membutuhkan biaya yang mahal dalam menganalisis gas, sehingga pengukuran secara tidak langsung atau prediksi dengan metode maksimal dan sub-maksimal dapat dijadikan alternatif untuk mengukur . Validitas tes , baik metode maksimal dan sub-maksimal sudah pernah dihitung akan tetapi secara terpisah pada populasi yang berbeda. Penelitian ini bertujuan membandingkan validitas dari tes metode maksimal dan sub-maksimal menggunakan subjek yang sama dengan waktu yang hampir sama. Validitas yang digunakan dalam penelitian ini adalah concurrent validity dengan Astrand Treadmill Test sebagai tes pembanding. 40 mahasiswa laki-laki (rerata usia 19,2 ± 0,6 tahun; rerata berat badan 68,3 ± 5,2 kg) dari Jurusan Pendidikan Jasmani dan Kesehatan Universitas Negeri Malang secara sukarela untuk berpartisipasi. Rerata hasil tes masuk kriteria good (45,2-50,9 ml. kg-1 .min-1 ) dan excellent (51.0-55.9 ml. kg-1 .min-1 ). Validitas dari MFT (0,88; p value = 0,037), Balke Test (0,90; p value = 0,003), Cooper Test (0,91; p value = 0,001) yang mewaliki tes metode maksimal. Validitas tes metode sub-maksimal diwakili Queens test sebesar 0,77 dengan p value = 0,067 dan Rockport test sebesar 0,75 dengan p value = 0,071. Validitas tes metode maksimal lebih bagus dalam memprediksi besaran daripada metode submaximal.Kata kunci: Validitas Tes, , metode maksimal dan sub-maksimal
