How can Archaeological Scientist Integrate the Typological and Stylistic Characteristics with Scientific Results: A Case Study on Bronze Spearheads Unearthed from the Shuangyuan Village, Chengdu City, Southwest China
Authors: Wang Xiaoting , Yang Yingdong , Wang Tianyou , Chen Dian , Luo Wugan
Published: January 2021

Background:

Bronze spears are weapons with unique regional characteristics of the Shu
culture, Southwest China in the Bronze Age, which reflect the bronze manufacturing tradition and
the utilization of mineral resources of ancestors. Previous studies mainly focused on the classification,
the alloy composition, or the production of bronze spearheads of the Shu culture. The purpose
of this paper was to make a comprehensive discussion on the Shu culture from the aspects of the
relationship between typology and scientific characteristics, the differences in metal raw material
selection with the Ba culture, and the contact with the culture in the Central Plains.

Methods:

In this study, typology, portable X-ray fluorescence spectrometry (pXRF) and multicollector
inductively coupled plasma mass spectrometry (MC-ICP-MS) were used to analyze thirteen
bronze spearheads unearthed from Shuangyuan site, an Eastern Zhou cemetery in Chengdu
City, Sichuan Province, Southwest China.

Results:

The results show that the spearheads can be classified into three types in typology. All
samples are tin-lead ternary bronzes, and the lead isotope data indicate the lead ore. Most spearheads
show ordinary lead, and only one spearhead has highly radiogenic lead.

Conclusion:

The typical Shu-style bronze spearheads have distinct shapes but similar ore materials.
Meanwhile, people of the Ba culture and the Shu culture used different metal sources to make
bronze spearheads. In addition, a very special bronze spearhead suggests that ancestors of the Shu
culture in the Eastern Zhou Dynasty imitated the late Shang culture in the Central Plains.

Authors: Yesilada Erdem , Akkol Esra K. , Aydin Ahmet , Hamitoğlu Muhammed
Published: January 2021

Background::

Oriental planetree (Platanus orientalis) leaf was recorded as a remedy against inflammatory problems and to stop pain, i.e. toothache or knee pain in “The Canon of Medicines” by Avicenna and was also being documented in the Iranian Traditional Medicine. Although such a utilization has not been described in the reliable sources, recently use of its leaves as herbal tea has become popular among the laypeople. Previous studies have shown that only the nonpolar extract from the leaves may have such an efficacy, while possible benefits when it is used as herbal tea have not been investigated.

Objective::

The present study aims to reveal the possible efficacy and safety profile of aqueous extract from P. orientalis leaf.

Methods::

Aqueous extract of the leaves was submitted to in vivo and in vitro tests to determine its anti-inflammatory, antinociceptive, antimutagenic activities and also reveal its safety profile.

Results::

The aqueous extract (400 mg/kg) procured weak and non-significant anti-inflammatory
and antinociceptive activities. Meanwhile, the aqueous extract demonstrated antimutagenic activity
in very high concentrations. On the other hand, results of safety evaluation showed that no concern
had been observed from the viewpoint of public health.

Conclusion::

Despite the popularity of the herbal tea prepared from the leaves of Oriental planetree among the people suffering joint problems to relieve pain, this study has proven that such application would not help them to alleviate their complaints when used as herbal tea.

Authors: López-Cervantes Jaime , Sánchez-Machado Dalia , de la Mora-López David S. , Sanches-Silva Ana
Published: January 2021

Background::

The pseudo-cereal quinoa has attracted worldwide attention in recent years, due to it being considered a functional food. This stress-tolerant crop has historically been used by Andean cultures as a staple food. Nowadays, the consumption of quinoa in high-income countries is increasing due to it being associated with numerous health benefits, namely related with cardiovascular health.

Objective::

We have carried out an extensive review on quinoa, including its main uses, applications, and components (nutrients, antinutrients, and bioactives) and their relationship with biological activities and cardiovascular health.

Key findings and conclusions::

Quinoa possess numerous activities, including protection against cardiovascular, metabolic, and degenerative diseases, improvement of the immune system, reduction of symptoms associated with post-menopause, and promotion of muscle mass increase. Some of quinoa’s activities are due to its balanced amino acid profile, high fiber content, presence of phosphorus, iron, potassium, magnesium, vitamin E, and B vitamins. A plethora of bioactives can also be found in quinoa, such as phytosterols, saponins, phenolics, bioactive peptides, and phytoecdysteroids. More research is needed to better understand the mechanisms of action involved in the biological/therapeutic action of some quinoa components, namely those related with the potential to reduce cardiovascular disease (CVD) risk markers. The knowledge of factors that affect quinoa variability, such as processing conditions, is also of great importance for being able to obtain more benefits from this crop.

n = 4200r/min Q = 90L/min, and H #8805: 4.4m. The flow, head, and efficiency and power of this electric
water pump will be discussed. And a brushless, direct current motor for this pump was designed and
analyzed.

Methods:

The flow details of the pump, such as pressure distribution, velocity distribution, and turbulent
kinetic energy distribution were obtained by Pumplinx. The head, efficiency, and power of the pump were
established by the analysis of the flow field of the pump. Then, based on the working conditions of the
pump mentioned above, a brushless direct current motor for the pump was designed by Maxwell and its
performance was also analyzed.

Results:

The experimental results showed that the maximum efficiency of the motor reached 72%, the
maximum efficiency point of the motor was near the rated speed, and the efficiency of the motor at rated
power was 66.31%.

Conclusion:

The results showed that the complex condition of running water inside the pump can be
exactly stimulated by the computational fluid dynamics technique, especially about the pump head and its
efficiency, which provided the theoretical foundation for the later application research and development
of automotive electronic water pump.

SIMULASI PENEMPATAN TRANSFORMATOR PADA JARINGAN DISTRIBUSI BERDASARKAN JATUH TEGANGAN MENGGUNAKAN ETAP POWER STATION 12.6.0
Authors: Safitri Fajar Dwi
Published: January 2021

Energi listrik dalam penyalurannya dari pusat pembangkitan, sistem transmisi, sistem distribusi sampai ke pusat beban mengalami jatuh tegangan. Hal ini terjadi karena jumlah konsumen PLN yang tiap tahunnya meningkat sehingga mengakibatkan bertambahnya panjang jaringan dan beban yang harus disuplai. Penelitian ini bertujuan untuk menganalisis jatuh tegangan pada Penyulang KLS06. Untuk melakukan perhitungan tersebut digunakan software ETAP Power Station12.6.0 dengan menggunakan metode Newton-Raphson. Jaringan distribusi Penyulang KLS 06 termasuk wilayah kerja PT PLN (Persero) ULP Semarang. Pada transformator distribusi 3 fasa 50 kV dengan nomor gardu KLS06-110 mengalami pembebanan yang melebihi batas standar. Sehingga pada Bus24 mengalami jatuh tegangan sebesar 3,75%. Berdasarkan SPLN 72: 1987 batas maksimum jatuh tegangan yang diijinkan pada JTR yaitu 4%. Untuk mempertahankan kualitas tegangan dan mengantisipasi terjadinya jatuh tegangan yang lebih besar akibat pertambahan beban, maka perlu dilakukannya sisip transformator yang dihubung paralel dengan transformator KLS06-110. Dari hasil analisis setelah dilakukan sisip transformator didapat nilai jatuh tegangan pada Bus24 berkurang 1,75% sehingga nilainya menjadi 2%.

The perspective of parents who support student diversity in school will open to a variety of different problems. The attitude is expected to encourage the implementation of integration and harmony among diversity. Therefore, the objective of the study was to describe the views of parents towards student diversity in inclusive education. Diversity from the perspective of parents determines the attitude of agree and disagree, as well as the right view of inclusive. The research method used a questionnaire to respondents of 99 parents from elementary schools in five regencies of the Special Region of Yogyakarta. The results showed that the majority of parents still had a narrow understanding that the concept of inclusive was the same with Student Educational Need (SEN). Here, the concept of labeling might understand as a misconception phenomenon. However, the majority of parents agreed to the SEN in regular schools, but an understanding of separate learning is the responsibility of the special supervisor or, interpreted as the inclusion officer. The implications need the education to understand the inclusion correctly and discuss the perspectives of parents to contribute to the success of learning in inclusive elementary schools.

The objective of the study is to develop the Contextual Teaching and Learning (CTL)-based functional academic teaching materials for the teachers specialized in educating the students with different visual ability. The method that has been adopted within the conduct of the study is Research and Development (R&D) with reference to the Borg & Gall Model by means of experiment limitation. The study itself has been conducted in the Yaketunis Special School Type A, which has been the school for the students with different visual ability in Yogyakarta. The results of the study, which cover the stages of needs analysis in the given special school, show that up to date there has not been any written systematic functional academic learning. In addition, the results of the study also show that the teachers still have been dealing with the efforts of teaching the functional academic because the curriculum has been the modification of the regular curriculum. Therefore, the teachers demand the functional academic teaching materials for the students with different visual ability. Based on the results of the expert judgment by the media expert, the material expert and the experiment with the teacher, the functional academic teaching materials have been declared good and fit for implementation in the school. Then, the aspects that have been assessed within the expert judgment are namely material/content, presentation, linguistic and graphic. Furthermore, the score by 3.65 from the media expert and the score 3.80 from the material expert imply that the product in the form of functional academic teaching materials have been very fit and good for implementation by the teachers specialized in teaching the students with different visual ability. In addition, the response within the experiment stage also show that the mean score has been 3.70; as a result, the product in the form of Contextual Teaching and Learning (CTL)-based functional academic teaching materials have good for implementation. In other words, it might be concluded that the Contextual Teaching and Learning (CTL)-based functional academic teaching materials have been feasible for implementation for the teachers specialized in educating the students with different visual ability in the terms of functional reading, writing and counting activities.

This research aims to describe the understanding of the concept of π numbers for elementary school pre-service teachers on circle materials. The research was conducted qualitatively and the type of research conducted was descriptive. The instruments used in this research were observation, interviews, and documentation. The research subjects involved were 45 elementary school pre-service teachers. The results of the research showed that understanding the concept of π numbers for elementary school pre-service teachers had the advantage of classifying objects based on whether or not the requirements that form the concept are fulfilled, identifying the characteristics of operations or concepts and developing the important requirements and/or sufficient requirements of a concept. On the other hand, understanding the concept of π numbers for elementary school pre-service teachers had weaknesses in indicators when applying the concept logically, giving examples or not examples of concepts learned, presenting concepts in various forms of mathematical representation (tables, graphs, diagrams, drawings, sketches, mathematical models, or others) and linking various concepts in Mathematics and out of Mathematics.
