Pertanggungjawaban Pidana terhadap Pelaku Abortus Provocatus Criminalis (Tindak Pidana Aborsi)
Authors: Wulandari Rini
Published: January 2021

Abortion is abortion, the release of the results of conception or fertilization prematurely. Unintentional fetal loss usually occurs in young pregnancies (one to three months). Sometimes a woman's pregnancy can die on its own without an act or intentional act. This is often referred to as "miscarriage" or spontaneous abortion. This often happens to motherswho are still pregnant, due to an unintentional and desirable result or because of an illness.If abortion due to rape is made an exception as a medical reason, then the criteria used as an exception must be absolutely clear and firm, so that it is not misused by irresponsible persons, consequently abortion is rife. Regarding the threat of criminal sanctions for perpetrators of provocatus abortion, in the criminal law (KUHP) it is formulated that there is a criminal threat for those who make an abortion. The Criminal Code does not care about the background or reasons for the abortion.Keywords : abortion, medical reason, criminal law

The Effects of Acidic and Basic Pumice on Physico-Mechanical and Durability Properties of Self-Compacting Concretes
Authors: Yücel Hasan Erhan , Öz Hatice Öznur , Güneş Muhammet
Published: January 2021

In this study, properties of self-compacting concretes (SCCs) containing acidic and basic pumice (AP-BP) was investigated. SCCs incorporating AP-BP (SCCAs-SCCBs) were produced with constant slump flow diameter of 720±20 mm and 690±20 mm by adjusting superplasticizer (SP), respectively. Control mixture was designed with totally crushed stone aggregate. SCCAs and SCCBs could be produced up to 100% coarse AP with 20% increments and 60% coarse BP with 10% increments, respectively, to ensure the desired limit values for SCC. Firstly, fresh properties of SCCs were determined. Then, the mechanical and durability properties of SCCs were measured at 28 and 56 days. Test results indicated that workability properties of SCCAs are markedly higher than that of SCCBs. Additionally, mechanical and durability performances of SCCs decreased with increasing of AP and BP. The compressive strengths of SCCs containing 60% AP and BP decreased approximately 28-29% and 22-24%, compared to the control mixture, respectively. Similarly, modulus of elasticity of same mixtures decreased around 35-39% and 17-19%, respectively. However, all results indicated that SCCs produced with AP and BP provided the available limits in the design of SCC. Additionally, SCCBs exhibited higher performance than SCCAs in terms of hardened properties. Moreover, high correlation coefficients (R2>0.89) between the durability and mechanical properties were found for SCCs.

Adab Berpakaian Wanita Muslimah Sesuai Tuntunan Syariat Islam
Authors: Alawiyah Syarifah , Handrianto Budi , Kania Rahman Imas
Published: January 2021

The phenomenon that afflicts Indonesian society, especially Muslim female students, is a culture of clothing that deviates from the guidance of Islamic law, although there are Muslim women who show how to dress according to Sharia, but the number is relatively small compared to those who are not. The phenomenon of wearing hijab is currently not in accordance with the requirements of Muslim women's clothing where not a few of the clothing models worn by women wearing hijab but still show the shape of the body, made from transparent and so on. Of course this is a problem that must be addressed by parents, educators and those in charge of education, because if it is left unchecked this will become a culture that will continue to develop and eventually become a law that is considered true by future generations. One way to overcome this is to raise awareness among Muslim women about the obligation to cover their genitals by providing sufficient understanding of genitals, the obligation to cover them and the adab of dressing in Islam. This study uses a literature review that synthesizes the theories and concepts of fiqh scholars about the aurat adab dress in Islam which then produces a concept of how to foster awareness of covering one's genitals which can be internalized in the form of dress behavior in Muslim women, especially students.

ABSTRAK : Setiap orang tua dengan anak berkebutuhan khusus umumnya memiliki stres pengasuhan yang lebih tinggi dibandingkan orang tua dengan anak normal, karena anak berkebutuhan khusus sangat membutuhkan perhatian dan perlakuan khusus yang lebih. Salah satu faktor yang dapat mempengaruhi tingkat stres tersebut adalah kualitas pernikahan. Sepasang suami istri dengan pernikahan yang berkualitas akan memiliki komunikasi dan interaksi yang baik antar keduanya sehingga stres pengasuhan pun dapat menurun. Tujuan dari penelitian ini adalah untuk mengkaji tentang hubungan dari kedua variabel tersebut. Penelitian ini dilakukan dengan metode kuantitatif menggunakan teknik pengambilan data quota sampling dengan subjek berjumlah 80 orang tua yang memiliki anak berkebutuhan khusus. Subjek diukur menggunakan skala berjumlah 63 item yang dimodifikasi dari Parenting Stress Index (PSI) dan skala kualitas pernikahan milik Allendorf & Ghimire (2013). Data dianalisa secara korelasional menggunakan product momment pearson. Hasil penelitian ini menunjukan bahwa kualitas pernikahan dan stres pengasuhan memiliki hubungan negatif yang signifikan dengan nilai (r = -293 ; p = 0.008), dimana saat orang tua memiliki kualitas pernikahan yang baik maka stres pengasuhannya akan semakin rendah.

Authors: Brtnik Bohumil , Matousek David , Stehlik Miroslav , Stejskal Vojtech
Published: January 2021

The signal processing at discrete time requires an aliasing filter at the input and a reconstruction filter at its output. In this paper, selected basic structures of biquads are described and compared with a view to the decrease of the attenuation over the transient frequency of the operational amplifier. Concretely, low-pass and band-pass Huelsman (i.e. multi feedback) structure are confronted with the limits of a real operational amplifier. Firstly, the reasons of the decreasing of the attenuation are explained theoretically. Secondly, these conclusions are verified by simulations. These simulations were performed by spice-like circuit simulator MicroCap version 10.
A New CMOS OP-AMP Design with an Improved Adaptive Biasing Circuitry
Authors: Ameziane Hatim , Zared Kamal , Qjidaa Hassan
Published: January 2021

This paper sets out a new technique for designing an operational amplifier (OP-AMP) using tanner EDA 1um FDSOI CMOS Technology. Fully Depleted Silicon on Insulator used for building integrated circuits to support the temperature changes, the proposed OP-AMP operates at 3.75V power supply and 70uA bias current using the proposed Adaptive Biasing Circuitry (ABC), which its devices operate at the weak inversion to allow low power dissipation of 0.62mW. The 0.064us settling time and 37.016V/μs slew rate parameters improved by the ABC technique, reducing the power dissipation by operating the ABC devices in weak inversion. The phase margin is more than 100 degrees for the DC gain of 13.97dB, which is a reasonable margin when temperature range increases.

Authors: Werneburg Ralf , Štamberg Stanislav , Steyer Jean-Sébastien
Published: January 2021

A new temnospondyl, Korkonterpeton kalnense gen. et sp. nov., is described on the basis of an almost complete specimen from the lover Permian Prosečné Formation of the Czech Krkonoše Piedmont Basin. The exceptional preservation of the holotype allows a detailed description of the cranial and postcranial characters: Korkonterpeton kalnense gen. et sp. nov. is characterized by the presence of vomerine fangs located anteriorly to the posterior choana, much longer than wide tabulars – as long as the supratemporals, a deeply concave posterior margin of the skull table, extraordinarily elongated exoccipitals, anteriorly widened pterygoids and a parasphenoid cultriform process swollen at its mid-length. In order to clarify the relationship between this new taxon and Intasuchus silvicola Konzhukova, 1956 from the lower Permian (late Kungurian) of the Russian Inta Basin, the latter is also redescribed here: Intasuchus silvicola exhibits a lacrimal entering the septomaxilla, a widened jugal, a posterolaterally widened interpterygoid vacuity, a subtemporal window elongated anteriorly up to the anterior orbital region, an elongated basipterygoid ramus which is as long as the orbit width, a vomer with a parachoanal tooth row, and an ectopterygoid of about the same length as the palatine. The description of Korkonterpeton kalnense gen. et sp. nov. and the revision of Intasuchus silvicola complete our knowledge on the origin and evolution of early stereospondylomorph temnospondyls during the lower Permian.

Published: January 2021

The first record of the seymouriamorph stem amniote Discosauriscus from the Krkonoše Piedmont Basin (the Czech Republic) is described. The specimen is identified as D. pulcherrimus on the basis of the following features which are absent in D. austriacus: 1) the pointed tip of the ventrolateral process of the postorbital lies anteriorly to the tip of the wedge-shaped dorsomedial process of the jugal; and 2) the rows of small denticles diverge anteromedially and anterolaterally from the midwidth of the ventral surface of the palatal ramus of the pterygoid. This new record increases our knowledge of the occurrence of this seymouriamorph in the Permo-Carboniferous basins of Europe.
Two cycads Nilssonia mirovanae sp. nov. and Pseudoctenis babinensis J.Kvaček from the Cenomanian of the Bohemian Cretaceous Basin (the Czech Republic) as indicators of water stress in the palaeoenvironment
Authors: Čepičková Jana , Kvaček Jiří
Published: January 2021

Nilssonia mirovanae sp. nov. is described from the Late Cretaceous Cenomanian of the Bohemian Cretaceous Basin. It comes from the best-exposed portion of the Peruc-Korycany Formation, in the Pecínov quarry, west of Prague, the Czech Republic. Although preserved only as a fragment of a pinna, it clearly shows haplocheilic stomata. In this paper, we compare N. mirovanae with Pseudoctenis babinensis J.Kvaček from the same horizon. These two cycads have similar adaptations for surviving water stress: thick cuticles and sunken stomata, characteristic features among gymnosperms indicating adaptation to xeromorphic plants, cuticle analysis, Late Cretaceousdrought.
A new eusuchian (Crocodylia) tooth from the Early or Middle Paleocene, with a description of the Early–Middle Paleocene boundary succession at Gemmas Allé, Copenhagen, Denmark
Authors: Wings Daniela Schwarz , Milàn Jesper , Gravesen Palle
Published: January 2021

A recently found crocodylian tooth crown from the basal conglomerate of the Middle Paleocene (Selandian) Lellinge Greensand Formation, differs morphologically from other finds of crocodylian teeth from the Paleocene of southern Scandinavia. The tooth is conical and blunt with a narrow rounded apex, and slightly curved along the axis of its length.

The morphology of the tooth suggests it belongs to either the longirostrine eusuchian Aigialosuchus, which is known from the Campanian of southern Sweden, or to a member of the Alligatoridae which are the most common crocodylians in northern Europe in the Late Cretaceous. Gavialoid crocodylians, in particular Thoracosaurus which is known from the Danian limestome of the Limhamn quarry in southern Sweden and from the Faxe quarry in eastern Denmark, can be excluded because of their deviating tooth morphology.

Regardless of its assignment, the tooth is interesting in a stratigraphic context as it demonstrates the existence of at least two crocodylian taxa in Scandinavia during the Early and Middle Paleocene.
The first evidence of trace fossils and pseudo-fossils in the continental interlava volcaniclastic sediments on the Faroe Islands
Authors: Pokorný Richard , Krmíček Lukáš , Árting Uni E.
Published: January 2021

Interlava volcaniclastic sediments, mostly sandstones, from the Palaeogene Faroe Islands Basalt Group (Malinstindur and Sneis Formations) contain rare ichnofauna and well-preserved pseudofossils in the form of linear structures. Five specimens of two ichnogenera have been identified, which include Helminthoidichnites isp. and ?Palaeophycus isp. The linear structures are interpreted to be desiccation cracks. This association indicates an environment with low to moderate hydrodynamic energy, which confirms a mosaic landscape of floodplains with rivers and shallow lakes.

Scanning helium-ion microscopy (HIM) is an imaging technique with sub-nanometre resolution and is a powerful tool to resolve some of the tiniest structures in biology. In many aspects, the HIM resembles a field-emission scanning electron microscope (FE-SEM), but the use of helium ions rather than electrons provides several advantages, including higher surface sensitivity, larger depth of field, and a straightforward charge-compensating electron flood gun, which enables imaging of non-conductive samples, rendering HIM a promising high-resolution imaging technique for biological samples. Starting with studies focused on medical research, the last decade has seen some particularly spectacular high-resolution images in studies focused on plants, microbiology, virology, and geomicrobiology. However, HIM is not just an imaging technique. The ability to use the instrument for milling biological objects as small as viruses offers unique opportunities which are not possible with more conventional focused ion beams, such as gallium. Several pioneering technical developments, such as methods to couple secondary ion mass spectrometry (SIMS) or ionoluminescence with the HIM, also offer the possibility for new and exciting research on biological materials. In this review, we present a comprehensive overview of almost all currently published literature which has demonstrated the application of HIM for imaging of biological specimens. We also discuss some technical features of this unique type of instrument and highlight some of the new advances which will likely become more widely used in the years to come.

The pitch processing of language and music is generally considered engaging overlapped neural correlates. Previous studies on musicians showed that the ability of pitch processing in music could be transferred to language. It is known that music training can facilitate neural processing of speech, however, the underlying neural mechanisms of pitch processing of language and music are not fully understood, especially in non-musicians. Using magnetoencephalography, we presented a pitch anomaly paradigm which consists of language/music phrases ending in either congruous or incongruous tones/pitches to non-musicians. We found the distinctive brain activity patterns in two groups with high and low musical pitch perceptual abilities. The brain-behavior results showed a positive correlation between the performance of musical pitch tasks and the activation of the left frontotemporal cortical regions elicited by lexical tones. Our results suggested that the cross-domain effect of language and music could be generalized to people without formal music training.

Published: January 2021

El neuromarketing como campo emergente de investigación combina herramientas derivadas de la neurociencia con la propia ciencia constitutiva del marketing, ofreciendo soluciones significativas, en muchos casos inéditas en su formulación, para sectores diversos de actividad y que contribuyen de modo decisivo a potenciar el desempeño e interacción entre la reacción del usuario y el estímulo proyectado hacia el mismo. Se plantea como objetivo central analizar desde una perspectiva teórica el neuromarketing, con la finalidad de precisar aquellas herramientas esenciales de aplicación y medición. Los resultados indican que, como campo emergente de investigación de mercado altamente controvertido, debe avanzar en el reconocimiento de las herramientas que mayor beneficio generan tanto para la academia como para el quehacer empírico. Las herramientas de medición utilizadas en estudios de neuromarketing (podrían también ser empleadas en estudios sujetos a los ámbitos de la neurocomunicación, neuropolítica, entre otros), en este sentido, cobran especial relevancia la electroencenfalografía y la actividad electrodérmica usadas para resolver problemas empresariales y de marketing. Los datos obtenidos desde la psicofisiología del posible cliente, suelen ser combinados también con respuestas de cuestionarios. A pesar de que su praxis puede implicar problemas de orden ético en aumento, su uso podría representar la solución a grandes desafíos.

PERSPECTIVE: Leadership in medical education: call to action
Authors: Do Victor
Published: January 2021

Leadership development in medical trainees is a frequent topic of discussion as we continue to grapple with better equipping physicians for the realities of “modern medicine.” Leadership is a critical competency for physicians to foster. Ironically, medical education rarely integrates leadership development into formal curricula. The conversations and formal policies around leadership development are relegated to the “hidden curriculum” of medical education. This paper describes the experience of Canadian medical trainees who pursue leadership opportunities and further training to develop leadership competencies in the context of relevant literature on leadership development. As leadership is a crucial competency to prepare physicians for medicine in 2020 and beyond, promotion of early leadership development in medical training is urgently required.

Published: January 2021

This paper exhibits performance of power of photovoltaic (PV) module in the case of shading effect. A comparison is made with performance of power of PV module void of MPPT solution. From the MATLAB simulation it is found that around 9.92% more average power generation is possible if MPPT (maximum power power point) solution is taken. To take the effect of partial shading a variation of irradiance profile has been proposed since change of irradiance causes the variation of output power to a great extent. Again to observe the performance of output power with MPPT Fuzzy logic control has been introduced for making the tracking fast and accurate. Mamdani control has been chosen as a technique for fuzzy controller. On top of this, mathematical structure of PV module has been prepared in MATLAB simulink to see output preview of PV module and this module has been linked to the fuzzy logic system to trace the peak power. In the simulation process the instantaneous power, average power and percentage power development are being analyzed with figures.
