The Failure Analysts' Mightiest Tool – Thrilling Fractography of Metallic Components

Published: January 2020

AbstractIn this contribution, some aspects of fractography are discussed, arguably the failure analysts' most potent analytical tool in metallurgical failure analyses. The characterisation of fracture surfaces is indispensable when it comes to getting to the bottom of things in regards to component failures. When machine parts or entire assemblies fail by fracture of individual members, the fracture surface contains the data that tells the failure analyst about the history of the failed component, and hopefully will also shed some light on the exact failure mode that eventually lead to fracture. That makes fractography, the art of reading fracture surfaces, so valuable. This applies to all material classes, i. e. metals, ceramics, and plastics alike. This paper, however, focuses on failures of metallic components only. When there is no fracture surface in a failed part, one is produced by forcing open cracks or other imperfections that might be suitable for this purpose. Once this is achieved, the failure analyst will open his or her toolset of macro- and microfractographic analysis equipment. It is not exaggerated to say that the scanning electron microscope (SEM) revolutionised the art of microfractography from the early 1960 s on. In this paper, a number of examples for this are given.

Authors: Oğur Hülya , Günaydın Rezzan , Rakıcıoğlu Neslişah 
Published: January 2020

Amaç: Bu çalışmanın amacı; romatoid artritli (RA) kadın hastaların beslenme durumunun saptanması ve fonksiyonel durum ile kas gücü arasındaki ilişkilerin incelenmesidir.
Bireyler ve Yöntem: Çalışma Romatoloji Polikliniği’ne kontrol amaçlı gelen, en az bir sene önce RA tanısı konmuş ve 10 mg’dan az metilprednizolon kullanımı olan 35-64 yaş arası kadın bireyler üzerinde gerçekleştirilmiştir. Çalışmaya katılmayı kabul eden hastaların beslenme durumu ve beslenme alışkanlıkları değerlendirilmiştir. Antropometrik ölçümler alınmış, bir günü hafta sonuna gelecek şekilde birbirini izleyen 3 günde bireysel besin tüketimi kaydedilmiş ve 24 saatlik fiziksel aktivite kayıtları sorgulanmıştır. Rutinde biyokimyasal parametrelere hasta dosyalarından ulaşılmıştır.
Bulgular: Hastaların ortalama 10.8±7.88 yıl önce tanı aldığı, 9.9±7.65 yıldır tedavi gördüğü saptanmıştır. Beden kütle indeksine (BKİ) göre hastaların % 9.9’u normal vücut ağırlığına sahipken, %46.5’i hafif şişman, %36.6’sı birinci derece obez, %7’si ise ikinci derece obezdir. Hastaların %88.7’sinin bel çevresi değeri ≥88 cm; %74.6’sının bel/kalça oranı 0.85’in üzerindedir. Bireylerin diyetle antioksidan alımlarına göre; C vitamini ile hemoglobin ve albümin seviyeleri, β-karoten ile karaciğer fonksiyon testleri, toplam kolesterol ve Serum-Reaktif Protein (CRP) arasında pozitif ilişki saptanmıştır (p˂0.05). Çoklu doymamış yağ asidi alımı ve alkalen fosfataz (ALP) değerleri arasında ise negatif ilişki bulunduğu gözlenmiştir (p˂0.05). Hastaların diyetle günlük ortalama enerji, karbonhidrat, potasyum, kalsiyum ve demir alımlarının gereksinmenin altında olduğu saptanmıştır.
Sonuç: RA’in tedavisinde, semptomların azaltılması ve yaşam kalitesinin arttırılmasında hastaların tanı sonrasında diyetisyene yönlendirilerek beslenmeye ilişkin bilgi düzeyleri arttırılmalıdır. Yine bu hastalarda değerlendirme yapılırken BKİ’nin yanı sıra vücut yağ yüzdesi ve kas gücü gibi yöntemlerin de kullanılması gerektiği sonucuna varılmıştır.
Alteration of Insecticide Resistance during the Aging of <i>Bactrocera cucurbitae</i> (Diptera: Tephritidae)
Authors: Verma D. , Kumari S. , Kumar D. 
Published: January 2020

The aim of the present investigation was to quantify the detoxification and stress enzymes’ levels and correlate it with insecticides resistance in different age groups of Bactrocera cucurbitae population. Different age groups of insect population were isolated and processed for enzymes assay and survival analyses.The increase in the activities of CytP450, esterase and superoxide dismutase (SOD) have been observed till certain age and thereafter they decreased. However, activity of glutathione-S-transferase (GST) and catalase did not increase with age. Results of survival assay showed that deltamethrin and malathion caused higher mortality in the 15-days old (100%) insects than the 1-day old adult insects. Highest survival percentage after deltamethrin treatment was found in 7 days old insects, whereas malathion treated insects’ survival was maximum in 3 days old insect population. Based on the above results, it is inferred that lack of sufficient GST and catalase cause decrease in the resistance of B. cucurbitae with advancing age.

Setiap organisasi memiliki aktivitas-aktivitas pekerjaan tertentu dalam rangka mencapai tujuan organisasi. Dalam usaha pencapaian tujuan pendidikan, peran manajemen sangat dibutuhkan dalam penyelenggaraan pendidikan.Bahkan manajemen memiliki kedudukan dan posisi yang sangat sentral dalam keseluruhan proses pendidikan serta merupakan syarat mutlak dan bagian yang tak terpisahkan dari pendidikan itu sendiri, karena manajemen sangat penting, maka menjadi tanggung jawab semua pihak yang terkait dalam proses penyelenggaraan pendidikan. Berkaitan dengan penyelenggaraan pendidikan, Peraturan Menteri Agama Republik Indonesia Nomor 56 tahun 2014 tentang Pendidikan Keagamaan Hindu yang didalamnya mengelola jalur pendidikan formal dan nonformal Hindu dalam wadah pasraman tentu membutuhkan pedoman dalam pengelolaan pendidikan tersebut baik dari segi perencanaan, pengorganisasian, pelaksanaan maupun pengawasannya. Yayasan Pasraman Gurukula Bangli merupakan yayasan yang mengelola lembaga pendidikan keagamaan bernuansa Hindu yang saat ini dalam proses perubahan status menjadi yayasan pendidikan keagamaan Hindu. Disamping itu juga yayasan tersebut satu-satunya yayasan yang ada di Bali dan bahkan di Indonesia yang mengelola dua jalur pendidikan bernuansa Hindu yaitu pendidikan formal yang terdiri dari SMP dan SMA Gurukula Bangli dan pendidikan nonformal berupa Pasraman Gurukula Bangli serta siswa Gurukula berasal dari anak-anak yang kurang mampu dari seluruh Indonesia yang beragama Hindu. Penyelenggaraan pendidikan tentu mengalami kendala-kendala baik itu kendala internal maupun kendala eksternal. Bertitik tolak dari fenomena tersebut di atas peneliti tertarik mengkaji lebih jauh mengenai Manajemen Pendidikan Keagamaan Hindu dengan judul “Pengelolaan Pendidikan Keagamaan Hindu di Yayasan Pasraman Gurukula Bangli Provinsi Bali”.

An increase of the mechanical strength and hardness of polymeric materials radiation-crosslinked by X-ray radiation from an gaseous electric discharge
Authors: Novikov G. K. , Fedchishin V. V. , Smirnov A. I. 
Published: January 2020

The problem of investigation of mechanical and electrophysical properties of polymeric materials crosslinked by X-ray radiation from a gaseous electric discharge is considered. The effect of radiation crosslinking on the mechanical strength and hardness of polymers is presented by the example of samples of various thicknesses (from 0.08 mm to 10 mm) of LDPE and HDPE made using crosslinking technology by X-ray radiation from a barrier gaseous electric discharge proposed in [1]. Experimental data obtained on samples of low molecular weight LDPE-107-02K and high molecular weight HDPE-271-82K made in the form of dumbbell, cut in accordance with GOST IEC 60811-2-1 from PE plates, are considered. To study the electrophysical properties and the depth of semi-absorption of X-ray radiation from gaseous electric discharge, LDPE and HDPE samples in the form of disks of different thicknesses were used.The depth of penetration of X-ray radiation from a gaseous discharge into LDPE-107-02K and HDPE-271-82K was estimated.Comparative studies of changes in the electrophysical properties of mechanical strength and hardness of cable LDPE under the influence of X-ray radiation from gaseous discharge and under the influence of an electron beam are carried out.It is shown that the mechanical strength and hardness of LDPE and HDPE can be increased by at least 30% and 60% respectively via radiation crosslinking by X-ray from a gaseous discharge.
PENGGUNAAN HUMOR DALAM DAKWAH KOMUNIKASI ISLAM
Authors: Wandi Wandi 
Published: January 2020

AbstractThe use of humor in da'wah of Islamic communication is something that is widely practiced by some preachers whether it is through religious pulpits or through the internet media called social media, humor is aimed to attract the attention of the audiences and be a part that is always awaited by the audiences in da’wah even though in fact, humor is only a complement in an Islamic da’wah, which is nothing else but to get attention from the audiences. However, the use of humor in the da'wah of Islamic communication sometimes backfires for those who do not pay attention to the standard criteria of humor such as ethical and aesthetic. Thus, based on the results of the analysis of the author that the use of humor in da’wah of Islamic communication is permissible and it becomes a good way as long as the preacher observes that in slipping his humor, he does not forget the propriety set out in the Qur'an and hadith. Keywords: humor, da’wah, Islamic communication
Sprawozdanie z polemiki Leszka Kołakowskiego z Józefem Marią Bocheńskim na łamach „Kultury” paryskiej oraz kilka wniosków dotyczących filozofowania w ogóle
Authors: Breczko Jacek 
Published: January 2020

W artykule tym przedstawiam skróconą historię „intelektualnych kontaktów” Józefa Innocentego Marii Bocheńskiego i Leszka Kołakowskiego (pomijam młodzieńczą, ortodoksyjnie marksistowską, napisaną w 1952 roku, krytykę Kołakowskiego książki Bocheńskiego Der sowjetrussische dialektische Materialismus oraz życzliwą recenzję Bocheńskiego książki Kołakowskiego „Główne nurty Marksizmu”). Koncentruję się na zdecydowanej polemice, która pozwala dostrzec różnice filozoficznych stanowisk i „stylów filozofowania”. Zaczyna się ona sporem o znaczenie Erazma z Rotterdamu na konferencji w Rapperswillu w roku 1986; jej kontynuacją była krytyczna ocena książki Bocheńskiego Sto zabobonów. Jerzy Giedroyc w liście do Kołakowskiego zauważył: „Rzeczywiście trudno z większą elegancją zniszczyć autora. Wyobrażam sobie jaka będzie reakcja Bocheńskiego”. Zaiste reakcja Bocheńskiego była gwałtowna, opublikował w roku następnym dwa artykuły, które były – przeważnie „nie wprost” – zdecydowaną polemiką z Kołakowskim i próbą precyzyjnego przedstawienia własnego stanowiska. Spór ten można potraktować jako ilustrację słynnego rozróżnienia Kołakowskiego na dwa typy aktywności w kulturze: kapłana i błazna.

Abstract
We report the first detection of galactic spiral structure by means of thermal emission from magnetically aligned dust grains. Our 89 μm polarimetric imaging of NGC 1068 with the High-resolution Airborne Wideband Camera/Polarimeter (HAWC+) on NASAs Stratospheric Observatory for Infrared Astronomy (SOFIA) also sheds light on magnetic field structure in the vicinity of the galaxy's inner-bar and active galactic nucleus (AGN). We find correlations between the 89 μm magnetic field vectors and other tracers of spiral arms, and a symmetric polarization pattern as a function of the azimuthal angle arising from the projection and inclination of the disk field component in the plane of the sky. The observations can be fit with a logarithmic spiral model with pitch angle of

and a disk inclination of 48° ± 2°. We infer that the bulk of the interstellar medium from which the polarized dust emission originates is threaded by a magnetic field that closely follows the spiral arms. Inside the central starburst disk (<1.6 kpc), the degree of polarization is found to be lower than for far-infrared sources in the Milky Way, and has minima at the locations of most intense star formation near the outer ends of the inner-bar. Inside the starburst ring, the field direction deviates from the model, becoming more radial along the leading edges of the inner-bar. The polarized flux and dust temperature peak ∼3″–6″ NE of the AGN at the location of a bow shock between the AGN outflow and the surrounding interstellar medium, but the AGN itself is weakly polarized (<1%) at both 53 and 89 μm.
