Rosetting Responses of Plasmodium-infected Erythrocytes to Antimalarials
Authors: Lee Wenn-Chyau , Russell Bruce , Lau Yee-Ling , Nosten Francois , Rénia Laurent 
Published: April 2022

ABSTRACT.
In malaria, rosetting is a phenomenon involving the cytoadherence of uninfected erythrocytes to infected erythrocytes (IRBC) harboring the late erythrocytic stage of Plasmodium spp. Recently, artesunate-stimulated rosetting has been demonstrated to confer a survival advantage to P. falciparum late-stage IRBC. This study investigated the rosetting response of P. falciparum and P. vivax clinical isolates to ex vivo antimalarial treatments. Brief exposure of IRBC to chloroquine, mefloquine, amodiaquine, quinine, and lumefantrine increased the rosetting rates of P. falciparum and P. vivax. Furthermore, the ex vivo combination of artesunate with mefloquine and piperaquine also resulted in increased the rosetting rates. Drug-mediated rosette-stimulation has important implications for the therapeutic failure of rapidly cleared drugs such as artesunate. However, further work is needed to establish the ramifications of increased rosetting rates by drugs with longer half-lifves, such as chloroquine, mefloquine, and piperaquine.
Origin and Functions of Chinese Seasonal Festivals Qingmingjie and Chongyangjie
Authors: Hein Evelina 
Published: April 2022

The article analyses the connection between Chinese folk calendar and the fundamental to the whole religious and social tradition of China ancestor worship. With the aim to clarify the role of folk calendar in the formation of the traditional culture, the author makes use of the theory of the Chinese philosopher Li Zehou about the development stages of the mankind evolution and civilization as stages of a process of sedimentation. The article presents two examples with the seasonal festivals Qingming and Chongyang, both dedicated to the ancestor worship. Origin, development and functions of this festivals are traced in the context of the ancestor worship and the culture of the filial piety (xiao), based on the latter. The author uses the Dual Filial Piety Model, developed by Bedford and Yeh and creates a consequent model for describing the functions of the festivals Qingming and Chongyang as a binary complex of corresponding rituals. Thеse rituals are analysed as fulfilling basic psychological and social needs of the members of the Han ethnic community in connection to the specific background of the culture of filial piety (xiao).

Between 2012 and 2014, 715 green coffee samples were gathered by Almacafé S.A. (Bogotá, Colombia) from 27 countries. These were analysed at the nuclear magnetic resonance (NMR) laboratory at Universidad del Valle (Cali, Colombia). Over 1000 methanolic coffee extracts were prepared and 4563 spectra were acquired in a fully automatic manner using a 400 ﻿MHz NMR spectrometer (Bruker Biospin, Germany). The dataset spans the variance that could be expected for an industrial application of origin monitoring, including samples from different harvest times, collected over several years, and processed by at least two distinct operators. The resulting 1D and 2D spectra can be used to develop and evaluate feature extraction methods, multivariate algorithms, and automation monitoring techniques. They can also be used as datasets for teaching, or as a reference for new studies of similar samples and approaches.
Design of an Automated Over-bed Hospital Meal Cart for Public Hospitals
Authors: Ayodeji Sesan P 
Published: April 2022

Hospital meal carts are used to deliver meals, drugs and some other materials to patients in the hospital environment. These carts which are moved manually by operators, the health workers, mostly do not comply with ergonomics guidelines and physical requirements of the equipment users in terms of anthropometry data of the region thus increasing the risk of musculoskeletal disorder among the meal cart users. Based on the preliminary study, most operators expressed the feeling of fatigue and postural discomfort in the shoulders, arms, back and thighs as a result of moving the hospital meal cart around the hospital environment. Also, patients who are limited in terms of sitting and standing needs this for their comfort and assistant. In order to ease this discomfort, an automated over-bed hospital table was designed using the adult working class anthropometry data of Nigeria. The cart has an adjustment feature of forth and back movement as well as height adjustment mechanism to suite the use of the patient. The responses obtained from ergonomic evaluation of the re-designed hospital meal carts were analyzed using SPSS to obtain the non-parametric Chi-Square test as well as the median and interquartile range. The test however showed significant difference when p < 0.050, hence the redesign is justified. The table can be operated by the patient with little or no assistance hence will reduce fatigue and risk of musculoskeletal disorder among the meal cart users. Keywords— Anthropometric data, Discomfort, Ergonomics, Hospital and Meal cart.

Published: April 2022

Bagian terlemah dari suatu sistem struktur baja terletak pada bagian sambungannya. Sambungan dapat berupa pelat buhul maupun pelat penyambung. Oleh sebab itu sambungan harus dirancang lebih kuat dan daktail dari komponen struktur yang merangka pada sambungan tersebut, seperti ditetapkan dan dijelaskan pada berbagai standar atau peraturan. Jembatan JUDESA merupakan solusi teknologi terkait jembatan untuk membuka aksesibilitas masyarakat desa melalui penyediaan infrastruktur jembatan sederhana yang mudah dibangun, efektif, dan efisien. Tujuan dari penelitian ini adalah mengetahui kapasitas dan klassifikasi sambungan struktur pylon jembatan gantung JUDESA pada Jembatan Pisang Binaya khususnya sambungan antar segmen kolom pylon berdasarkan kekuatan dan kekakuan sambungan akibat gaya-gaya dalam yang terjadi setelah penambahan kombinasi beban gempa sesuai dengan peraturan/code gempa yang terbaru SNI 1726-2019. Penelitian ini dilakukan dengan kajian secara numerik menggunakan analisis elemen hingga (finite element) dengan memodelkan jembatan secara utuh (jembatan gantung) dengan menggunakan software SAP 2000 Versi 14.2.2 dengan beban layan operasional dan juga beban gempa. Proses analisa pada sambungan dilakukan dengan bantuan software IDEA StatiCa. Berdasarkan hasil analisis yang telah dilakukan maka dapat disimpulkan bahwa profil, plat penyambung dan juga baut pada jembatan JUDESA masih jauh dari kemampuan maksimum dari semua komponen penyambung (baut, pelat, dan profil). Hasil finite element menunjukkan bahwa tegangan yang terjadi sebesar 37,7 mPa, ini menunjukkan bahwa tegangan yang terjadi hanya sekitar 15 % dari kemampuan bahan penyambung baik pelat penyambung maupun profil yang disambung. Gaya tarik yang terjadi pada baut maksimum sebesar 0,2 kN, dan geser maksimum yang terjadi pada baut sebesar 1,1 kN ini menunjukkan bahwa gaya tarik dan geser yang terjadi pada baut hanya sekitar 0,1 % dari kemampuan bahan baut.

Prioritas penanganan jalan didasarkan pada pertimbangan yang kompleks dengan mengakomodasi aspek yang bersifat teknis dan nonteknis. Pendekatan yang dapat mengakomodasi aspek yang bersifat multikriteria adalah Analytic Hierarchy Process (AHP) dan Analytic Network Process (ANP). AHP merupakan pendekatan yang bersifat preferrence dengan model yang berbentuk hirarki, sedangkan ANP merupakan pendekatan yang bersifat influence dengan model yang berbentuk jaringan. Tujuan dari penelitian ini adalah menentukan prioritas penanganan ruas jalan Batas Kota Rantau Prapat – Aek Nabara – Sp. Kota Pinang – Bts. Propinsi Riau dengan menggunakan metode AHP dan ANP menggunakan 4 (empat) kriteria. Data hasil analisis menunjukkan bahwa dari 4 (empat) kriteria yang diambil dalam penelitian ini dengan mengunakan metode AHP yakni faktor kondisi jalan (0,523) merupakan kriteria yang paling dominan, diikuti faktor biaya (0,261), faktor lalu lintas (0,141) dan kebijakan (0,075). Selanjutnya untuk memperoleh bobot akhir yang lebih objektif dilakukan analisis dengan metode ANP karena memungkinkan dilakukan feedback terhadap elemen dan klasternya sendiri yakni faktor kondisi jalan (0,4138) merupakan kriteria yang paling dominan, diikuti faktor biaya (0,2566), faktor lalu lintas (0,1846) dan kebijakan (0,1450). Berdasarkan hasil analisis dalam penentuan urutan prioritas dengan metode AHP, maka dapat diurutkan prioritas penanganan jalan nasional yaitu Ruas Batas Kota Rantau Prapat – Aek Nabara menjadi prioritas pertama kemudian diikuti Ruas Sp. Kota Pinang – Bts. Provinsi Riau dan Ruas Aek Nabara – Sp. Kota Pinang. Selanjutnya untuk mendapatkan hasil yang lebih stabil dan lebih akurat dalam penentuan urutan prioritas digunakan metode ANP dan didapatkan hasil yaitu Ruas Batas Kota Rantau Prapat-Aek Nabara menjadi prioritas pertama kemudian diikuti Ruas Sp. Kota Pinang-Bts. Provinsi Riau dan Ruas Aek Nabara-Sp. Kota Pinang. Perolehan urutan prioritas penanganan jalan dengan metode AHP pada penelitian ini sama hasilnya dengan menggunakan metode ANP.

An Evaluation of Volume Excavation and Core Sampling Techniques for Measuring Soil Bulk Density
Authors: Lichter J.M. , Costello L.R. 
Published: April 2022

AbstractSoil bulk densities were measured at three locations representing a variety of textural classes utilizing two measurement techniques: core sampling and volume excavation. Bulk density values established by the volume excavation method were significantly lower than core sampling values at 2 of 3 locations. The differences in bulk densities generated by the two techniques should be considered when evaluating the severity of compaction on a site relative to an assumed critically limiting bulk density. Core sampling is a simple, fast and common technique, but is not suitable for sampling rocky, dry or wet soils. The volume excavation method requires simple to use and inexpensive tools and was useful for sampling soils of various conditions, but this technique required greater care in sampling technique which increased the time required for sampling.
Variation Among Alnus Progenies Grown in Ohio
Authors: Townsend A.M. , Douglass L.W. 
Published: April 2022

AbstractSeedlings grown in Ohio from seed collected from 12 native seed sources ofAlnusglutinosa(European black alder) and one seed source ofAlnus cordata(Italian alder) were outplantedin 1981 in a combination provenance/family planting. Data were collected over a period of 11 years after planting. Results show highly significant variation among provenances in winter injury, time of growth initiation, rate of survival, leaf miner injury, and height and diameter growth. Italian alder seedlings showed the least leafminer injury and the earliest flushing, but showed the poorest survival of all groups tested, primarily because of winter injury. European black alder seedlings grown from seed collected in Iran also sustained major winter dieback and poor survival. Trees from West Germany, France, Denmark, and Yugoslavia seed sources were fastest-growing, whereas seedlings from some sources in southern Europe (Spain, Italy, Bulgaria) were slowest - growing. The genetic variation shown in this study is sufficient to allow for success in breeding for improved insect resistance, cold hardiness, and growth rate in alder.
Mycoplasmalike Organisms as Causes of Slow Growth and Decline of Trees and Shrubs
Authors: Sinclair Wayne A. , Griffiths Helen M. , Lee Ing-Ming 
Published: April 2022

AbstractMycoplasmalike organisms are obligate parasites of plants and insects. In recent years, advances have been made in detecting and identifying them, distinguishing among those associated with various plant diseases, assigning them to groups based upon homology of DNA base sequences, and determining their roles in decline of trees and shrubs. These advances are reviewed with special reference to ash yellows and elm yellows. Known and probable relationships among MLOs associated with various plant diseases are tabulated.
Effects of Leaf Removal, Leaf Tying, and Overhead Irrigation on Transplanted Pygmy Date Palms
Authors: Broschat Timothy K. 
Published: April 2022

AbstractThe effects of leaf removal, leaf tying, and overhead irrigation during transplanting were determined using mature pygmy date palms(Phoenix roebelenii).In one experiment palms had all, 2/3, or none of their leaves removed and were irrigated overhead or on the soil surface only. In the second experiment, palms had 2/3 of their lower leaves removed and those remaining were eithertied up into a bundle or left untied. Half of the palms in each experiment were irrigated daily while the other half were subjected to water stress cycles. Results showed that leaf tying had no positive effect on the palms, but when coupled with overhead irrigation, was responsible for fungal infections in the crowns of some palms. With regular irrigation, palm quality and root growth were increased as the number of leaves retained was increased, but under water stress conditions, the reverse was true. Overhead irrigation had no positive effect on transplanted palms.
Environmental Adaptation and Ornamental Display of Cornus florida Ecotypes
Authors: Heatley R. C. , Kielbaso J. J. , Howell G. S. 
Published: April 2022

AbstractA flowering dogwood (Cornus florida) rangewide provenance study was begun in 1972 in Michigan. One block was planted on an open hilltop and another under the shade of another plantation. Trees from 18 states were rated for fall color; from 15 states for cold hardiness, flowering, and presence of stem cankers. Northern seed sources were hardier when grown in the open than under shade. Fall color was best for northern sources grown in the open; shaded trees developed minimal color. Use of northern seed sources should provide hardier trees with better fall color displays and better flowering in northern landscapes.
