Improving seed germination and seedling growth of maize (Zea mays, L.) seed by soaking in water and moringa oleifera leaf extract
Authors: Ahmed Abeer A. , El-Mahdy Amal A.
Published: March 2022

Germination traits are the key factor in higher productivity of crops. Thus, laboratory tests were made to enhance the germination of the seeds. One of the best strategies to promote seed germination was soaking the seeds in water and Moringa leaves extracts (MLE.) before planting. This experiment was carried out to evaluate the optimal soaking duration to enhance seed germination and seedling growth of hybrid 178 maize. There were three soaking durations; 12 hours, 16 hours, and 20 hours, along with the un-treatment (0 hour or without soaking). While the other factor was the concentration of the soaking seeds solution in Moringa leaves extract which was (0.25, 0.5 and 1.00 g) at the ratio of 1:10 (w/v) beside to hydro-priming (soaking in water) and control (un-treatment), each with four replications. Seed germination (%), germination index (GI), germination speed index (SGI), germination rate (GR, day), mean germination rate (MGR, day), seedling shoot length (cm), seedling root length (cm), seedling length (cm), seedling fresh weight (g), seedling dry weights, (g) seedling vigor 1 (SV1) and seedling vigor 2 (SV2) were evaluated. Results showed that maximum value germination traits were found in hybrid 178 of Maize which soaked at 20 hours of duration, followed by soaked at 16 hours then at 12 hours soaking compared with un-soaked seed. The germination and seedling characters, improved with soaking in Moringa leaves extract. 0.25 g/mm MLE. was the best treatment, followed by 0.5 (g) and hydro-priming gave higher values, as to seed germination and seed vigour compared with other treatment. Field emergence experiment gave the best values for dry weight(g) and seedling vigour (SVII) with 0.25 g/mm then 0.5 g/mm and hydro-priming under soaked seed to 20 hour com. This suggests that soaking in Moringa leaves extract as 0.25 concentrate under 20 hour soaking was a suitable treatment that can improve germination and seedling growth in hybrid 178 maize.
An investigation on dynamic behavior of rotating shafts using a pipe elbow finite element formulation
Authors: Sajjadpour M. , Kordkheili S. A. Hosseini
Published: March 2022

Rotating shafts have a vast application in various industries especially in the aerospace industry such as engines, compressors and turbines. The researchers have performed considerable efforts on the rotating shafts’ dynamic behavior because of their sensitivity to the rotor specifications and different parameters such as supports. In this paper by employing a pipe elbow element, an especial finite element formulation is derived to investigate dynamic behavior of rotating shaft in the presence of support clearance. The proposed element consists of four nodes with twenty-four degrees of freedom, which also accounts for the shear and gyroscopic effects. Within a finite element analysis framework, the focus of the paper is proposing a formulation to account for the dynamic behavior of a rotating shaft with much less number of elements. The element is implemented in a finite element code and then is used to model and analyze some rotating shaft examples. In order to verify the developed formulation, results are compared with those obtained from other schemes reported in the literature.

Published: March 2022

Nowadays, in order to increase construction of tall structures, the importance of choosing optimum systems, with a huge energy absorption capacity against wind and earthquake loads, has been widely considered. Since four decades ago, steel shear walls had been used as a stiff and high performance lateral system. This study is about the effect of concrete filled steel tubes (CFT) columns as vertical boundary elements of steel shear wall on seismic behavior of steel structures. Due to do this, three 10-storey steel structures, with similar plans and lateral load career systems of steel shear wall, coinciding X-bracing, and moderate steel frame were analyzed by means of non-linear, time-history method through SAP2000 software, and the results of roof displacement of them were compared with each other. Also after validating a two-storey, single-span frame sample with steel shear walls and CFT columns, 3 single-storey structures were analyzed by means of hysteresis and pushover, through ABAQUS software. The results of this study showed that a shear wall system presents suitable stiffness, resistance and ductility in comparison with other lateral bearing systems.

Study of typology and morphology of stupa variety at the Padepokan Dhammadipa Arama in Malang, East Java
Authors: Sugata Ferlina , Venny
Published: March 2022

Religious people generally have a symbol of respect to worship the greatness of role models in their respective religions. This is motivated by different traditions, history, locations, and developments of religion and worship activities that affect the emergence of various types and forms of worship. One of them is a building named stupa. The stupa building as a means of worship accommodates worship activities in Buddhism. The stupa also functions as an object of respect in implementing worship. Padepokan Dhammadipa Ārāma's premises in Malang are architectural stupas buildings similar to the Patirupaka Stupa Shwedagon in Myanmar. Therefore, this study aims to determine the extent to which this replication process occurs in terms of typological and morphological studies, to analyze typology by classifying stupas based on the types of stupas in the world where each culture has its characteristics, and to analyze morphology based on the level of change and tendency of change. The method of this study is a qualitative study with a rationalistic approach. The study results are tabulations of typology and morphology of stupa architecture as a guide for the types and forms of stupa architecture, contributing to the science of Buddhist religious architecture in the Indonesian Archipelago.

Chalcophile Element Heterogeneity in Ni-Cu-(Platinum Group Element) Orebodies of Raglan Horizon in Cape Smith Belt: Implications for Ore-Forming Processes
Authors: Li Ying Zhou , Mungall James E.
Published: March 2022

The komatiitic Raglan Horizon in northern Quebec hosts one of the largest komatiite-associated magmatic sulfide deposits in the world. Several studies have suggested that the sulfide ores were formed by melting and transporting sedimentary sulfides from upstream after the komatiite melt had assimilated a large amount of S-rich country rocks. In this study, we report new compositional data of the sulfide ores in Zones 5-8 and 13-14 along with the legacy assay database to investigate variability of the ore-forming processes at Raglan at the camp scale. More than 90,000 drill core samples were selected, and the rocks are categorized into disseminated, net-textured, and massive sulfide based on their sulfide abundance. We demonstrate that the majority of the compositional variability of the sulfide-bearing rocks can be attributed to the difference in the mass ratio between silicate and sulfide melts (R factor), by applying thermodynamic modeling of silicate and sulfide magma evolution. The massive sulfides display depletions in Cu, Pd, and Pt that are best explained by sulfide liquid fractionation, which differentiates the residual Cu-, Pd-, and Pt-rich sulfide liquid from the Ni-rich monosulfide solid solution (MSS) cumulate now preserved within the massive sulfide ores. A small population of sulfide-bearing samples that is strongly depleted in all the economically important metals has been interpreted to represent externally derived xenomelts that were poorly equilibrated with the metal-rich host magma due to low residence time. A portion of massive sulfides has been found to be depleted in Pd and Cu but not Pt. This decoupling of these metals can be well explained by a postmagmatic process that persisted to temperatures as low as 300°–350°C. Similar depletions of Pd have also been observed in the Expo Intrusive Suite immediately to the south. The regional variations in the compositions of individual orebodies suggest that they occurred in highly localized environments that record only local magmatic conditions and that the sulfide mineralization did not reach equilibrium with a single regionally continuous silicate magma system. Each zone preserves a unique signature of assimilation, sulfide segregation, and sulfide crystallization; hence, they likely represent separate magmatic pulses within the larger Raglan system. Lastly, based on the spatial locations of the low tenor sulfides, we tentatively suggest that Zone 2 and the Katinniq zone are more proximal to the as-yet-unidentified eruption site of the Raglan komatiite lava flow field.

A presente pesquisa foi desenvolvida no contexto de confinamento social obrigatório, decretado como uma das medidas implementadas no estado do Rio de Janeiro em consequência da pandemia originada pelo Covid19. É uma pesquisa quali-quantitativa, exploratória, de caráter descritivo que recorre a um questionário online para coleta de dados e, assim, se apresenta na forma de um levantamento. Pela sua particularidade, esta pesquisa também se enquadra no que se considera um estudo de caso. Tem como objetivo principal, averiguar qual o impacto do isolamento social obrigatório na sociabilidade e nas interações sociais dos estudantes do Colégio e, em particular, analisar a forma que os estudantes do Colégio Pedro II encontraram para vivenciar o isolamento social obrigatório e indagar quais os seus sentimentos e vivências no período de quarentena. A maioria dos estudantes revelou compreender e apoiar as medidas de isolamento que foram impostas à população, salientando que o bem comum deve ser colocado em primeiro lugar. No entanto, manifestaram desconforto quanto ao momento de incerteza que é vivido, reconhecendo que esse período de quarentena prejudicou suas vidas nos diversos domínios. Saudade, tristeza e ansiedade foram os sentimentos que os estudantes mais referem, destacando-se o papel importante que o colégio e o ambiente escolar desempenham nos seus afetos. Alguns dos questionamentos colocados no início da pesquisa foram completamente respondidos, mas em contrapartida, como consequência de um momento de grande pressão social, em que o stress emocional individual originado pela pandemia trouxe à tona alguns elementos que contribuíram para a ressignificação do papel da instituição escolar junto ao jovem estudante, outros questionamentos e desafios se colocam.

Authors: Gargya G. , Sharma A. , Vasistha H.B.
Published: March 2022

Study was undertaken to understand the population size and distribution of Nardostachys jatamansi vis-à-vis phyto-associates at three subsites containing highly dense (Subsite-1), moderate (Subsite-2) and lowest population (Subsite-3) of N. jatamansi. The community composition between the sub sites was observed a very little difference with recoding 13, 15 and 12 species respectively in Subsite-1, Subsite-2 and Subsite-3. About 80% species were common in all Subsites, while 6.66% species were common in two Subsites and 13.32% species were observed unique in all subsites. Intra-site comparisons indicate that N. jatamansi and Anaphalis triplinervis had the mutualism type of interaction with one another. Picrorrhiza kurrooa, Anemone obtusiloba, Pyrus sp. and Saxifraga diversifolia showed the negative correlation with N. jatamansi. The populations of these phyto- associates appear to adversely affect with the population of N. jatamansi for utilization of resources. Pedicularis sp., Carex sp., Saussurea sp., Tanacetum longifolium, Saxifraga sp. and Araiostegia sp. showed the neutral type of interaction with N.jatamansi, which indicates that, the population of Nardostachys jatamansi is not affected by association with these species.
Direito e força: breves considerações acerca da conexão (não)necessária entre direito e coerção em Frederick Schauer
Authors: Farage da Costa Felipe Bruno , Marcelo Hara Johnny , Menezes de Jesus Renata , da Silva Crespo Bastos Danuza , Coelho Medina Lízia
Published: March 2022

Em “O conceito de direito”, H.L.A Hart traz uma reflexão que acaba servindo de base para a criação da figura do puzzled man (ou homem perplexo), muito refletida nos debates jusfilosóficos acerca da conexão entre direito e coerção. A ideia do puzzled man construída por Hart tem relação direta com algumas premissas de sua teoria do direito: o “homem perplexo” indica que muitas pessoas obedecem às leis mesmo sem estarem preocupadas com a sanções advindas de seu descumprimento. Contudo, será que realmente podemos afirmar que o uso da força é dispensável na delimitação da natureza do direito? Uma obra mais recente, do autor Frederick Schauer – The Force of Law - lança novas bases para a reflexão dessa premissa. O presente artigo esboça uma revisão, com pesquisa bibliográfica, cujo objetivo não é realizar uma crítica à Schauer com argumentos pós-positivistas, mas sim demonstrar a complexidade dos argumentos trazidos em The force of law e como, na maioria dos casos, são argumentos acertados. Uma das grandes contribuições do autor, a meu ver, reside na exploração de uma perspectiva até então utilizada como argumento, mas sem profundidade, a partir da figura do puzzled man. Se muitas pessoas obedecem às regras, pelo simples fato de serem regras, por que isso acontece? Em linhas gerais, Schauer defende a hipótese de que é possível explicar o direito a partir do seu viés coercitivo, mas reduzi-lo a esse elemento seria um erro. Assim, Schauer defende que a coerção, um aspecto tão central para autores como Bentham e Austin, surge como elemento contingente e não necessário, sendo “útil, mas não essencial, ubíqua, mas não universal” e, portanto, não faz parte da própria natureza do direito. Partindo do pressuposto de que a coerção é uma característica presente no direito, mas não essencial para a afirmação de sua natureza, a preocupação de Schauer passa a residir na explicação dos fatores que fazem as pessoas a internalizarem as regras de direito e a obedecê-las. Segundo o autor, existem diversas razões pelas quais alguém respeita o direito, mas não por medo da sanção. Dentre elas temos duas marcantes: I) por questões preferenciais; II) por um misto de racionalidade e moralidade. Em suma: o direito não se explica somente pelo viés coercitivo, mas dar menor relevância ou excluir a participação desse conceito na definição de “o que é direito”, não seria condizente com a realidade.

Mean Meridional air-motion and associated transport process in the atmosphere
Authors: RAO M. S. V.
Published: March 2022

Eliassen's equation of quasi-static balance has been rederived in a more suitable frame of co-oridinates and, by making certain simplyfying assumptions, rendered into a form which lends itself easily to solution by relaxation. The differential equation thus obtained is solved for extended sources of heat and momentum similar to those actually encountered in the troposphere. The results show a mean meridional circulation consisting of a strong direct cell in low latitudes and a week indirect cell in the middle latitudes.

In section 3 of the paper, starting from the idea that the mean meridional circulation is split up into cells and making use of the values of the strength of the circulation deduced by Tucker and Mintz, the sources and sinks of heat and momentum necessary to maintain such mean motion are evaluated. Further, an attempt is made to infer what the character of eddy motion in the meridional plane has to be in order to satisfy balance requirements.

Comparison of Short, Intermediate, and Long Cephalomedullary Nail Length Outcomes in Elderly Intertrochanteric Femur Fractures
Authors: Womble Tanner N. , Kirk Andrew , Boyle Maxwell , Comadoll Shea M. , Su Leon , Srinath Arjun , Matuszewski Paul Edward , Aneja Arun
Published: March 2022

Introduction:

Cephalomedullary nail (CMN) length for intertrochanteric femur fractures without subtrochanteric extension has been an ongoing debate. The authors hypothesize that increasing nail length would result in increasing surgical time, greater incidence of acute kidney injury (AKI), postoperative anemia, and blood loss requiring transfusion due to increased intramedullary reaming and pressurization of the canal with nail insertion.

Methods:

A retrospective chart review of patients aged 65 years or older who underwent CMN for low-energy intertrochanteric femur fractures from 2010 to 2018 was undertaken. Patient demographic data, comorbidities, case duration, postoperative hospital length of stay (LOS), and laboratory data, including serum creatinine, hemoglobin, and hematocrit, were collected for analysis. The following outcome measures were compared: postoperative pneumonia, cardiac complications, sepsis, reintubation/intensive care unit stay, pulmonary embolism, stroke, postoperative AKI, 30-day hospital readmission, 30-day return to operating room, 30-day mortality, 1-year mortality, postoperative anemia (hemoglobin <7 g/dL), and blood transfusion.

Results:

A total of 247 patients were analyzed (short = 48, intermediate = 39, and long = 160). No notable difference was observed in postoperative pneumonia, cardiac complications, sepsis, reintubation/intensive care unit stay, pulmonary embolism, stroke, mean total hospital LOS, mean postoperative hospital LOS, rate of postoperative AKI, 30-day readmission, 30-day return to operating room, 30-day mortality, or 1-year mortality. Patients receiving long nails had significantly higher rates of postoperative anemia (P = 0.0491), blood transfusion (P = 0.0126), and mean procedure length (P = 0.0044) compared with the two other groups.

Discussion:

Patients receiving long nails had markedly higher rates of postoperative anemia and blood loss requiring blood transfusion with markedly longer mean procedure length than patients receiving short and intermediate CMNs. Long nails did not result in an increase in other complications evaluated.

Introduction:

The toy industry has grown substantially over time, with billions of dollars of toys sold each year in the United States alone. Even after safety considerations, injuries can result. This study examined toy-related fractures in the US Emergency Departments (ED).

Methods:

The 1999 to 2018 National Electronic Injury Surveillance System from the US Consumer Product Safety Commission was examined data for fractures involving a toy-related injury. The incidence, trends, and anatomic locations for such fractures were assessed.

Results:

In total, 347,135 toy-related fractures were identified, of which 237,754 (68%) were in patients younger than 18 years, 182,516 (53%) were sustained by male subjects, and a 95% yearly incidence increase was observed over the years of the study. Anatomically, 37% were shoulder/arm/elbow, 24% wrist/hand/finger, 19% ankle/toe/foot, 10% leg/knee, 6% face/neck/head, and 4% trunk/pubic region.

Discussion:

Despite safety considerations with toy design, more than a third of toy-related fractures were seen in the ED, with a nearly doubling yearly incidence over the study period. This could be contributed to by increased production and prevalence of toys and/or rougher play and increased overall violence. These results are important not only for patient safety but also for orthopaedic surgeons, EDs, toy manufacturers, and policymakers.

ZTP (Zero Touch Provisioning) adalah sebuah inovasi dalam dunia IT, yang merubah cara melakukan konfigurasi perangkat yang sebelumnya manual menjadi otomatis. Inovasi ini tercipta dikarenakan semakin banyaknya kebutuhan akan perangkat jaringan. Tantangan tersendiri bagi perusahaan jaringan untuk mengelolanya baik dari sisi waktu dan biaya. Pada metode tradisional, Administrasi perangkat jaringan harus masuk ke setiap perangkat jaringan satu persatu untuk melakukan konfigurasi. Hal tersebut tentunya tidak efisien. Disinilah kelebihan dari otomasi, konfigurasi perangkat jaringan menjadi lebih efisiensi, ditambah pekerjaan yang sifatnya repetitive seperti backup konfigurasi, monitoring, bisa dilakukan dengan otomatis.  Pada penelitian ini penulis akan menguji sebara efisien penggunaan dari ZTP dengan cara membandingkan waktu konfigurasi dengan cara manual dan otomasi dengan ztp. Konfigurasi yang akan di lakukan pada penelitian ini adalah konfigurasi IP Address, membuat DHCP server, dan membuat hotspot pada MikroTik. Untuk memudahkan melakukan manajemen jaringan penulis membuat dashboard untuk mengetahui perangkat mana yang sudah dikonfigurasi. Sistem otomasi sendiri dibuat dengan menggunakan pemrograman Python yang memanfaatkan library utama Paramiko sebagai penghubung antara perangkat jaringan dengan server otomasi melalui protokol SSHv2.
