Published: April 2022

This article focuses on the design and manufacture of mechanical parts that have complicated shapes using the technique of reverse design using a scanner or an MMT for data acquisition in the form of a point cloud, using CAD software (CATIA). The digital model created is used for a virtual representation of the final product. Then we get the physical model on a 3D printer (also called additive manufacturing process) for later use in sand moulds. To have the imprint in the sand mould, we go through the fusion of the physical model (part). The use of this technique in the industry, allows us to save a lot of time in terms of model preparation and simple to implement, especially if it is mechanical parts that do not have a definition drawing, or they are worn out, then structural analysis was applied on the model using FE based software and tools to prove the quality of the product. Von Mises equivalent strains and stresses were predicted and decreased with increasing areas and honeycomb thickness. The objective of this article is to give an overview of this relatively modern technology and its various applications.

Published: April 2022

Elastic strain is covered by the effective medium homogenization method inside a representative volume element (RVE). It has an incremental quasi rate-independent (QRI) form obtained by the endochronic concept of thermodynamic time. The rate dependence takes place by means of stress rate dependent value of the initial yield stress. Free meso rotations and constrained micro rotations within a representative volume element (RVE) are assumed. A comparison between QRI and J2 diffuse instability equations is presented for orthotropic materials. A new QRI nonlinear evolution equation for orthotropic materials is derived by tensor function representation with Spencer-Boehler structural tensors.

Ivhu rinotsamwa: Landscape Memory and Cultural Landscapes in Zimbabwe and Tropical Africa
Authors: Sinamai Ashton
Published: April 2022

Perceptions of the various cultural landscapes of tropical Africa continue to be overdetermined by western philosophies. This is, of course, a legacy of colonialism and the neo-colonial global politics that dictate types of knowledge, and direct flows of knowledge. Knowledges of the communities of former colonised countries are seen as ancillary at best, and at worst, irrational. However, such ‘indigenous knowledge’ systems contain information that could transform how we think about cultural landscapes, cultural heritage, and the conception of 'intangible heritage’. In many non-western societies, the landscape shapes culture; rather than human culture shaping the landscape – which is the notion that continues to inform heritage. Such a human-centric experience of landscape and heritage displaces the ability to experience the sensorial landscape. This paper outlines how landscapes are perceived in tropical Africa, with an example from Zimbabwe, and how this perception can be used to enrich mainstream archaeology, anthropology, and cultural heritage studies. Landscapes have a memory of their own, which plays a part in creating the ‘ruins’ we research or visit. Such landscape memory determines the preservation of heritage as well as human memory. The paper thus advocates for the inclusion of ‘indigenous knowledge’ systems in the widening of the theoretical base of archaeology, anthropology, and heritage studies.

Authors: Kunimatsu Natsuko , Kunimatsu Akira , Uchida Yoshihiro , Mori Ichiro , Kiryu Shigeru
Published: April 2022

Objectives

To investigate the application of apparent diffusion coefficient (ADC) histogram analysis in differentiating between benign and malignant breast lesions detected as non-mass enhancement on MRI.

Materials and Methods

A retrospective study was conducted for 25 malignant and 26 benign breast lesions showing non-mass enhancement on breast MRI. An experienced radiologist without prior knowledge of the pathological results drew a region of interest (ROI) outlining the periphery of each lesion on the ADC map. A histogram was then made for each lesion. Following a univariate analysis of 18 summary statistics values, we conducted statistical discrimination after hierarchical clustering using Ward’s method. A comparison between the malignant and the benign groups was made using multiple logistic regression analysis and the Mann-Whitney U test. A P -value of less than 0.05 was considered statistically significant.

Results

Univariate analysis for the 18 summary statistics values showed the malignant group had greater entropy (P < 0.001) and lower uniformity (P < 0.001). While there was no significant difference in mean and skewness values, the malignant group tended to show a lower mean (P = 0.090) and a higher skewness (P = 0.065). Hierarchical clustering of the 18 summary statistics values identified four values (10th percentile, entropy, skewness, and uniformity) of which the 10th percentile values were significantly lower for the malignant group (P = 0.035).

Conclusions

Whole-lesion ADC histogram analysis may be useful for differentiating malignant from benign lesions which show non-mass enhancement on breast MRI.

of colloidal particles and macromolecules, and their developments. The scaling and fractal concepts allowing a quantitative description of the aggregate structure are introduced. The influence of aggregation mechanism on the structure of the resulting aggregates is also discussed. Because
of the complexity of these mechanisms, computer simulations combined to experimental verifications is a powerful tool to investigate and understand aggregation processes in many applications.
Sunlight-Induced DNA Lesions. Lesion Structure, Mutation Characteristics and Repair
Authors: Carell Thomas
Published: April 2022

The UV part of sunlight is known to induce a variety of genome defects. These lesions are the major cause of skin cancer development. In order to counter such toxic effects cells have developed a number of sophisticated DNA repair systems, like nucleotide excision repair and photoreactivation. The repair machinery is able to specifically recognize sunlight-induced DNA lesions and to subsequently remove this damage. Malfunctioning repair systems are responsible for the three rare genetic diseases Xeroderma pigmentosum, Cockayne's syndrome, and trichothiodystrophy. In this review article, the structure of the major sunlight-induced lesions will be discussed. An overview of the two major repair mechanisms, photoreactivation and excision repair, is given, and the effects of the DNA lesions on the p53 gene and on tumor genesis are discussed.

Accelerating ab initio QM/MM Molecular Dynamics Simulations with Multiple Time Step Integration and a Recalibrated Semi-empirical QM/MM Hamiltonian
Authors: Pan Xiaoliang , Van Richard , Epifanovsky Evgeny , Liu Jian , Pu Jingzhi , Nam Kwangho , Shao Yihan
Published: April 2022

Molecular dynamics (MD) simulations employing ab initio quantum mechanical and molecular mechanical (ai-QM/MM) potentials are considered to be the state of the art, but the high computational cost associated with the ai-QM calculations remains a theoretical challenge for their routine application. Here, we present a modified protocol of Multiple Time Step (MTS) method to accelerate ai-QM/MM MD simulations of condensed-phase reactions. Within a previous MTS protocol [Nam, J. Chem. Theory Comput., 2014, 10, 2175], reference forces are evaluated using a low-level (semi-empirical QM/MM) Hamiltonian and employed at inner time steps to propagate the nuclear motions. Correction forces, which arise from the force differences between high-level (ai-QM/MM) and low-level Hamiltonians, are applied at outer time steps, where the MTS algorithm allows the time-reversible integration of the correction forces. To increase the outer step size, which is bound by the highest-frequency component in the correction forces, the semi-empirical QM Hamiltonian is re-calibrated in this work to minimize the magnitude of the correction forces. The remaining high frequency modes, which are mainly bond stretches involving hydrogen atoms, are then removed from the correction forces. When combined with Langevin or SIN(R) thermostat, the modified MTS-QM/MM scheme remains robust with an up to 8 fs (with Langevin) or 10 fs (with SIN(R)) outer time step (with 1 fs inner time steps) for the chorismate mutase system. This leads to an over 5-fold speedup over standard ai-QM/MM simulations, without sacrificing the accuracy in the predicted free energy profile of the reaction.
Screening for Generality in Asymmetric Catalysis
Authors: Wagen Corin C. , McMinn Spencer E. , Kwan Eugene E. , Jacobsen Eric N.
Published: April 2022

Research in the field of asymmetric catalysis over the past half century has resulted in landmark advances, enabling the efficient synthesis of chiral building blocks, pharmaceuticals, and natural products. A small number of asymmetric catalytic reactions have been identified that display high selectivity across a broad scope of substrates; not coincidentally, these are the reactions that have the greatest impact on how enantioenriched compounds are synthesized. We postulate that substrate generality in asymmetric catalysis is rare not simply because it is intrinsically difficult to achieve, but also because of the way chiral catalysts are identified and optimized. Typical discovery campaigns rely on a single model substrate, and thus select for high performance in a narrow region of chemical space. Here, we put forth a practical approach for using multiple model substrates to select simultaneously for both enantioselectivity and generality in asymmetric catalysis from the outset. Multisubstrate screening is achieved by conducting high-throughput chiral analyses via supercritical fluid chromatography-mass spectrometry (SFC-MS) with pooled samples. When applied to Pictet–Spengler reactions, the multi-substrate screening approach revealed a promising and unexpected lead for the general enantioselective catalysis of this important transformation.
Non-metal to metal transition of magnesia supported Au clusters affects the ultrafast dissociation dynamics of adsorbed CH3Br molecules
Authors: Vaida Mihai E. , Rawal Takat B. , Bernhardt Thorsten M. , Marsh Brett M. , Leone Stephen R.
Published: April 2022

The detection of intermediate species and the correlation of their ultrafast dynamics with the morphology and electronic structure of a surface is crucial to fully understand and control heterogeneous photoinduced and photocatalytic reactions. In this work, the ultrafast photodissociation dynamics of CH3Br molecules adsorbed on variable size Au clusters on MgO/Mo(100) is investigated by monitoring the CH3+ transient evolution using a pump-probe technique in conjunction with surface mass spectrometry. Furthermore, extreme-ultraviolet photoemission spectroscopy in combination with theoretical calculations are employed to study the electronic structure of the Au cluster on MgO/Mo(100). Changes in the ultrafast dynamics of CH3+ fragment are correlated with the electronic structure of Au as it evolves from monomers to small nonmetallic clusters to larger nanoparticles with a metallic character. This work provides a new avenue to a detailed understanding of how surface photoinduced chemical reactions are influenced by the composition and electronic structure of the surface.

Land degradation and soil erosion are the major problem in the world. The world loses 24 billion tons of fertile land and dry land degradation reduces National domestic product in developing countries by up to eight percent per year which indicates the vulnerable threat to millions of people in the world. About 87 tonnes of topsoil per hectare per year eroded in Nepal. The fragile geology, farming practices, increasing population etc are the reason which exceeding erosion in Nepal. Soil conservation practices include erosion control and fertility maintenance as well. Agro-forestry system using Pectona grandis, Acacia nilotica, Dalbergia sissoo etc play an important role in soil conservation. Cowpea, Velvet bean, sesbania, blackgram etc as a cover crop intercept the splash effect of raindrops, improve infiltration of soil and also to reduce deleterious effects of global warming. Conservation tillage was found effective against both soil and wind erosion. Mulching, contour farming and terracing are also found effective in the hilly mountaineous region. It was also found effective in Nepalese condition as well. In this paper bird’s eye view on soil erosion issue, reason and major conservation practices in Nepal and world as well.

Published: April 2022

Access to safe drinking water is an emerging issue in Pakistan, both in urban and rural settlements. The water quality in the region is mainly declined by population explosion, vehicular and industrial emissions and agricultural activities. The aim of the study was to assess the water quality of the study area through integrated approach of water quality index and multivariate analysis. Water samples from the study area were analyzed for physicochemical and microbiological parameters using standard methods. The study site was divided into eight (8) different locations and the water samples were collected from commonly used water sources. The results of study indicated that the concentration of all studied chemical parameters were within the permissible limits when compared with WHO recommended standards except lead (Pb). Major cations were found in the order of Ca2+> Mg2+>Na+ whereas the trend of anions was HCO-3>Cl->SO4>NO3.Overall water was estimated to be of CaHCO-3 type. Water quality index illustrated that all water samples were unsuitable for drinking purposes. Microbiological assessment showed that water is contaminated with coliform bacteria and fungal spores. Multivariate techniques were found to be ideal tools in identifying spatial variability through cluster analysis (CA) and reducing the dimensionality of huge data set through PCA/FA. It is briefly, concluded from the results of current study, that water of the study area was unsuitable for drinking purposes due to presence of some biological and chemical contaminants. Results recommend that developing efficient water quality monitoring programs, promoting ceramic filters technology, and raising awareness about the issue in communities are the most important steps that might help the people of the study area to resolve the problem.

This paper reviews the background and developments of air filters based on electrospun nanofiber materials. Methods of electrospinning in the production of filter materials and their advantages are discussed in detail. Researchers around the globe are working hard to get highly efficient filters at low cost. Famous approaches to build most effective air filters include electrospun nanofiber mats, composite nanofiber mats, and antibacterial nanofiber mats for micro to nano level filtration at a higher rate. Properties like high temperature, alkali, acid, and flame resistance are still constraining the use of nanofiber filters in many industries. Future research should be focused on producing nanofiber mats capable of undergoing extreme conditions.
CONSIDERAȚII DESPRE REFORMA LITURGICĂ ROMÂNEASCĂ DIN SEC. AL XVII-LEA: MOLITFELNICUL DE LA BĂLGRAD
Authors: QARAMAH Mihail K.
Published: April 2022

This paper discusses the place of the Romanian Euchologion printed in 1689 at Bălgrad (today Alba Iulia, Romania) in the liturgical reform of the Orthodox Church of Transylvania during the 17th c. The author aims to establish that the apparition of the Euchologion of Bălgrad was not only the product of Calvinist Reformation, which insisted on the translation of the liturgical orthodox texts into the vernacular language, but also the result of the liturgical reform undergone by the Orthodox Church of Wallachia. After a summary presentation of the context of liturgical reform in the Romanian Church during the 17th century, the author offers a brief comparison of the contents of the Euchologion of Bălgrad and the Slavonic Trebnik printed at Câmpulung (Wallachia) in 1635, which inaugurated the domination of the Ruthenian liturgical practice in the Church of Wallachia, as an effect of the church reform supported by Metropolitan Peter Mohyla of Kiev. The comparison led to the conclusion that the former was mostly a Romanian translation of the latter, with some adaptations, which reflect either local usages or changes caused by the dynamic of the liturgical practice. The apparition of the Euchologion of Bălgrad aimed the correction and standardization of the byzantine-slavic rite in Transylvania and the initiation of the faithful through the translation of euchological texts into the vernacular. Its large circulation through manuscript copies until the 19th century demonstrates the value of this book in the liturgical life of the Romanian Orthodox Church of Transylvania

Abstrak - Perkembangan kota Bandung sangat pesat dengan munculnya bangunan-bangunan modern di hampir diseluruh kota Bandung, keadaan ini disebabkan oleh kebutuhan kota yang semakin beragam dan bangunan cagar budaya ikut terkena dampak, karena diubah fungsinya sesuai dengan kebutuhan. Banyak bangunan cagar budaya yang fungsinya berubah namun tidak memperhatikan keaslian bangunannya sehingga kondisinya jadi memprihatinkan.  Dari sekian banyak bangunan cagar budaya di Bandung hanya sedikit yang  masih terlihat keasliannya walaupun sudah berubah fungsinya. Studi ini akan mengangkat isu pengaruh perubahan fungsi pada keaslian bangunan cagar budaya dengan fokus pada fungsi dan bentuk, dengan kasus studi Gedung Tigawarna. Penelitian ini mengedepankan cara baca baru yang menggabungkan teori Fungsi-Bentuk-Konstruksi dan teori Pelestarian. Gedung Tigawarna, tampak dari luar masih terlihat keasliannya, namun pada pengolahan interior banyak yang sudah berbeda dari aslinya, karena perubahan fungsi dari bangunan rumah tinggal dan kantor menjadi bangunan bank BTPN. Namun bentuk diupayakan dipertahankan keasliannya, antara lain dengan menggunakan material yang sama atau mirip dengan aslinya, baik eksterior maupun interiornya. Manfaat dari penelitian ini diharapkan memberikan kontribusi pengetahuan arsitektur bagi masyarakat, masukan bagi para akademisi dan mahasiswa Arsitektur, juga dapat menjadi masukan bagi pemegang kebijakan dalam menyusun strategi  pelestarian bangunan cagar budaya.

Seyahat ve Otel İşletmeciliği Dergisi (SOİD) Makalelerinin Bibliyometrik Analizi (Bibliometric Analysis the Journal of Travel and Hotel Business Articles)
Authors: Ünüvar Şafak , Yurtlu Murat
Published: April 2022

Bu çalışma, Türkiye’de turizm alanyazınındaki akademik dergiler içerisinde 2019 yılında etki faktörü en yüksek olarak belirlenen Seyahat ve Otel İşletmeciliği Dergisi’nde 2018, 2019 ve 2020 yıllarında hakem denetimli yayımlanmış toplam 104 makalenin bibliyometrik profilini belirlemeyi amaçlamaktadır. Bu kapsamda SOİD yayınlarını örneklemine alan ilk çalışmadır. Çalışmanın amacı doğrultusunda makalelerin analizi için bibliyometrik parametreler geliştirilerek biçimsel kriterler, içeriksel kriterler, araştırma deseni ve yazar bilgileri kategorileri (4 kategori) ve bu kategorilere ilişkin kriterler (21 kriter) oluşturulmuştur. Araştırma örnekleminde incelemeye alınan makaleler, geliştirilen bu parametrelere ait model çerçevesinde analiz edilmiştir. Araştırmanın bazı bulgularına göre; makalelerin yayın onay sürecinin daha çok 61-90 gün aralığında olduğu, makalelerin konularına göre en fazla incelenen konuların başında bireylerin algılarına, tutumlarına, davranışlarına ve niyetlerine yönelik kişilik özelliklerinden oluştuğu belirlenmiştir. Araştırma evrenlerine ilişkin olarak en fazla turizm işletmelerinin incelendiği ve bu işletmelerden konaklama işletmelerinin daha fazla ele alındığı saptanmıştır. Araştırmalarda nicel araştırma yaklaşımların ağırlıklı olduğu gözlenmiştir. Bununla birlikte veri toplama tekniklerinde nicel araştırma yaklaşımlarında daha çok anket tekniğinden, nitel araştırma yaklaşımlarında ise daha çok yazılı kaynaklardan yararlanıldığı saptanmıştır. Ayrıca alternatif turizm türlerine ilişkin Gastronomi Turizmi, Kültür Turizmi gibi konularla birlikte Sosyal Medya ve Seyahat Motivasyonu konularına yönelik çalışmaların en fazla atıf alan araştırmalar olduğu sonucuna ulaşılmıştır.

Published: April 2022

Çalışmada; Hiyerarşik Boş Zaman Kısıtlamaları Teorisi (HBZKT) çerçeve olarak kabul edilmiş, kadın seyyahların, turizm süreçleri ve davranışları teorik bir temel üzerinden açıklanarak, turizm literatüründeki boşluğu doldurmada yararlanılmasına çalışılmıştır. Araştırmada kullanılan Yalnız Başına Seyahat Kısıtlaması Ölçeğinin (YBSKÖ) güvenirlik ve geçerlik analizleri 862 (501 kadın ve 361 erkek) katılımcı üzerinden yapılmış ve ölçeğin genel güvenirliği cronbach alpha=0.902 olarak çok yüksek bulunmuştur. Araştırma bulguları kadın katılımcılarla sınırlandırılmıştır. Faktör analizi sonucunda değişkenler toplam açıklanan varyansı %60.928 olan 5 faktör (içsel kısıtlamalar, yurtiçi destinasyon nitelikleri, zaman ve maliyet, yurtdışı destinasyon nitelikleri ve kişilerarası kısıtlamalar) altında toplanmıştır. Araştırmadan elde edilen bulgulara göre katılımcıların “içsel kısıtlamalar”, “yurtiçi destinasyon nitelikleri”, “yurtdışı destinasyon nitelikleri”, ve “kişilerarası kısıtlamalar” ortalamalarının “zayıf”, “zaman ve maliyet” kısıtı ortalamasının “orta” düzeyde olduğu sonuçlarına ulaşılmıştır. Araştırmanın sonuçları genel olarak kadınların yalnız başına seyahatlere katılımları için güçlendirilmeye, desteklenmeye ve teşvik edilmeye ihtiyaç duyduklarını, karar vericilerin, uygulayıcıların ve akademisyenlerin üzerine farklı sorumluluklar yüklediğini göstermektedir.
