Volcanic Soils: Their Characteristics, Management Practices, and Potential Sollution for Water Pollution
Authors: Anggriawan Rendy , Ariska Salsabilla Nuryana , Ayu Prahesti Imelda
Published: June 2023

Volcanic soils are formed from materials originating from volcanic eruptions, and with various pedogenic processes occurring, volcanic soils have unique physical, chemical, and biological characteristics. This paper aims to review the characteristics of volcanic soils, constraints, management practices, and their potential as adsorbents for contaminants. The paper was based on secondary information using a systematic review. The studies carried out include identifying manuscripts, analyzing report data, critically assessing the topic, and combining the results of relevant published manuscripts. The issues raised include data on volcanic soils, management practices, water pollution, and using volcanic soils as an environmentally friendly adsorbent. Colloidal compounds in the clay fraction of volcanic soils generally contain active Al and Fe compounds, allophane, imogolite, ferrihydrite, or Al/Fe-humus complex, and together with opaline silica. The volcanic soil material produces a pool of Al and Fe solid phases with high reactivity, which contributes to the unique physicochemical properties of Andisol. The main problem chemically is the high adsorption of phosphate and nitrate ions which causes the fertilization process to be inefficient. The main problem affects the adsorption of phosphate and nitrate on agricultural lands, so fertilization becomes inefficient. However, the high reactivity of volcanic soils can be used as a basic pollutant adsorbent. This is quite a promising opportunity, given the wide distribution of volcanic soils, so this resource is a very prospective candidate as an adsorbent material in water purification.
Development of Small-Scale Integrated Farming Design: towards Optimizing Agricultural Learning Media
Authors: Sustia Dewi Ni Kadek Ema , Umami Arif
Published: June 2023

Learning about integrated farming could be done by visiting site locations directly. This is a problem for universities that are located in urban areas. The distance of the integrated agricultural location from the campus often raises a significant cost burden. Therefore, providing a learning model around the university would be more efficient, and students could interact and practice directly. The design concept was compiled based on a literature review. The design was produced by direct observation at Condongcatur experimental garden, then continued SWOT analysis. The design was created using software based on the information gathered. The design development included a general description of the experimental garden, landscape biophysical aspect, concept planning, and design. The resulting design was then validated by experts descriptively using a questionnaire. Meanwhile, user acceptance was measured qualitatively through an interview. Based on the results obtained, theoretically, a small-scale integrated farming design has been successfully compiled and met the requirements to be developed as an agricultural learning model. The design also received a good response from the management, which would then be followed up in the long-term development plan of the experimental garden.

Sengketa tanah yang sering timbul di masyarakat diawali dengan banyaknya kasus atau tanda-tanda hak atas tanah lama yang tidak hilang ketika diubah menjadi sertifikat, sehingga banyak pihak yang memiliki pipil atau sertifikat dari negara yang sama. Sedangkan pipil atau sejenisnya merupakan bukti kepemilikan tanah, sebelum Undang-undang No. 5 Tahun 1960 tentang Agraria, yang menyatakan bahwa sertifikat adalah bukti kepemilikan tanah yang sah. Oleh karena itu, persoalan ini berkaitan dengan bagaimana kekuatan pipil membuktikan hak atas tanah sebelum sertifikat diterbitkan dan sengketa tanah ulayat di desa adat Guwang diselesaikan pada saat sertifikat. Penelitian ini menggunakan jenis penelitian hukum empiris dan pendekatan sosiologis. Hasil dari penelitian ini adalah Pipil merupakan bukti sahnya kepemilikan hak-hak lama sebelum lahirnya Undang-Undang Pokok Agrari (UUPA) dan Sertipikat merupakan bukti sahnya pemilikan tanah menurut UUPA. Untuk sengketa adat Desa Guwang yang hak milik atas tanahnya disebutkan dalam Pasal 19(2)(c) UUPA, sertifikat merupakan alat bukti yang kuat, yaitu keterangan fisik dan hukum yang terdapat dalam surat pernyataan tidak menjadi penentu sengketa adat Desa Guwang.

Scientists share several periods of the development of Islamic law from time to time. The periodization of Fiqh is divided into 6, namely; Minutes period, khulafaurrasyidin period, fiqh growth period, golden period, period of review and debate, and period of decline. However, the main focus of this article is tasyri 'in the period of the Prophet. There are three formulations of the problem in this research, namely: How is the history of the development of Islamic law during the period of the Prophet? What was the method of establishing Islamic Law during the Prophet's period? Did the Prophet have ijtihad ?. The purpose of this research is to find out the history of the development of Islamic law during the Prophet's period, to find out what the method of establishing Islamic law in the Prophet's period was, to find out whether the Prophet had ijtihad. The research method used was the library research method. By using normative and socio-historical approaches. The results showed that the history of the development of Islamic law during the Prophet's period was twofold, namely the Mecca period, namely before the Prophet's migration to Medina. The Medina period, which is after the Messenger of Allah moved to Medina. Meanwhile, there are three methods of determining Islamic law at the time of the Prophet, namely gradual, making laws more efficient and providing convenience and relief. As for the Prophet's ijtihad, there are two groups of opinion: the Asy'ariyah group and the majority of the Mu'tazilah saying there is no Prophet's ijtihad.

DISKURSUS WANITA MUSLIMAH: Versi Al-Quran dan As-Sunnah
Authors: Jailani Mulyadi Bin
Published: June 2023

Islam emphasizes that men are protectors of women. Men and women are given by Allah swt advantages and specialties to complement each other. The physical advantages of men and women's reproductive organs should not be understood as advantages or disadvantages, but both must be directed to carry out their functions proportionally. Women in the view of Islam actually occupy a very respectable position. The view of Islam cannot be said to be gender biased. Islam does sometimes talk about women as women (for example in terms of menstruation, pregnancy, childbirth and breastfeeding obligations) and sometimes also speaks as humans without being distinguished from men (for example in terms of the obligations of prayer, zakat, hajj, noble character, amar makruf nahi munkar, eat and drink lawful and so on). Both views aim at directing women individually as noble human beings and collectively, together with men, to become part of a harmonious order (family and society).

Ambiguous high scores: The All-Russian Olympiad in economics during the COVID-19 pandemic
Authors:   Moscow State University, CMASF, Moscow, Russian Federation, Magzhanov Timur , Sagradyan Anna ,   Moscow State University, Moscow, Russian Federation
Published: June 2023

This paper evaluates the change in the contribution of factors to the probability of students’ success at the All‐Russian Olympiad in economics during the COVID‐19 pandemic using classical econometric models and binary quantile regression (BQR). No works were found in the Russian literature where BQR would be applied. However, in our opinion, it has great potential both for studying the effects’ heterogeneity and for solving probability prediction problems. Empirical results show that the contribution of school rating to success at the municipal stage decreased in the 2020/21 season compared to the 2019/20 season. High score at the municipal stage (winner status) became a weaker predictor of success at the regional stage in the 2020/21 season compared to the 2019/20 season. The reason for this change may lie in a decrease in the tasks’ complexity (due to a change in their structure), a higher opportunity for cheating (due to weak and non‐mandatory proctoring) or both.

Increased Accuracy in Blockchain-Based Intrusion Detection and Prevention System
Authors: Aliyu Ahmed , Liu Jinshuo , Gilliard Ezekia
Published: June 2023

Intrusion Detection and Prevention (IDPS) is a critical cybersecurity
task that involves monitoring network traffic for malicious activity and
taking appropriate action to stop it. However, insufficient training
data or improperly chosen thresholds often limit the accuracy of such
systems, resulting in high false positive rates. To improve the accuracy
of an IDPS, blockchain technology can be used. Blockchain technology
provides a secure, decentralized, immutable ledger that can track
suspicious activity over time and identify intrusions globally. Security
teams can use blockchain technology to create immutable records of
suspicious activity, give users visibility into the system, and improve
the accuracy of intrusion detection systems. In this paper, we propose a
novel methodology to improve the accuracy of blockchain-based intrusion
detection and prevention systems, which is based on combining different
intrusion detection algorithms and using a blockchain-integrated
architecture. Our experimental results show that the proposed system
significantly increases the accuracy while reducing the false positive
rate, opening up new opportunities for the development of highly
accurate networks.
Ecology, ethnobotany, and potentially suitable habitat of Arisaema costatum (Wall.) Mart. under the climate change scenarios in Nepal
Authors: Thapa-Magar Santosh , Awasthi Manisha , Karki Sangram , Poudel Basu , Chung Ki Wha
Published: June 2023

The unique landscape of Nepal supports diverse ecological niches that
are home to valuable plants, benefiting various ethnic groups. Wild
edible plants have been essential for the livelihoods of indigenous
peoples and local communities due to their affordability, ease of
harvest, and renewable nature. However, climate change is altering the
habitat, distribution, ecology, and phenology of plant species in the
Himalayas. One such important species in Nepal is Arisaema
costatum, which has multiple indigenous uses. Unfortunately,
deforestation and land use changes have led to continuous changes in the
distribution and habitats of wild edible plants. We conducted field
research involving 280 quadrats (2×2 meters) and 210 interviews. By
utilizing MaxEnt modeling and considering different climate change
scenarios (Shared Socioeconomic Pathways 4.5 and 8.5) as well as
climatic predictors and species localities, we analyzed 196geospatial
data points. This allowed us to evaluate the present suitable
environment and predict potential habitats in 2050 and 2070. Our
findings revealed that A. costatum is used as a vegetable by
indigenous and local communities in the Nepal Himalayas. Traditional
fermentation and detoxification techniques are employed for its
preparation. The plant plays a vital role in household food and
nutrition, income generation, and health security. Elevation, annual
mean temperature (BIO-1), and precipitation during the warmest and
coldest quarters (BIO-18 and BIO-19) were identified as the most
influential factors for projecting the future distribution of A.
costatum in the Nepal Himalayas. Approximately 14% (21121.75 km2) of
Nepal’s land was found to be suitable habitat for this species, with the
Gandaki, Bagmati, and Koshi provinces in the temperate regions
particularly well-suited compared to other provinces. Given the
anticipated loss of A. costatum habitats and the increasing
temperatures due to climate change in the Nepal Himalayas, urgent
integrated research and development programs are necessary to address
this issue.
Geometric Active Disturbance Rejection Control of Rotorcraft on SE(3) with Fast Finite-Time Stability
Authors: Wang Ningshan , Hamrah Reza , Sanyal Amit Kumar , Glauser Mark N.
Published: June 2023

This article presents a tracking control framework enhanced by an
extended state observer for a rotorcraft aerial vehicle modeled as a
rigid body in three-dimensional translational and rotational motions.
The system is considered as an underactuated system on the tangent
bundle of the six-dimensional Lie group of rigid body motions, S E ( 3 )
. The extended state observer is designed to estimate the resultant
external disturbance force and disturbance torque acting on the vehicle.
It guarantees stable convergence of disturbance estimation errors in
finite time when the disturbances are constant and finite time
convergence to a bounded neighborhood of zero errors for time-varying
disturbances. This extended state observer design is based on a
Hölder-continuous fast finite time stable differentiator that is similar
to the super-twisting algorithm, to obtain fast convergence. A tracking
control scheme that uses the estimated disturbances from extended state
observer for disturbance rejection, is designed to achieve fast
finite-time stable tracking control. Numerical simulations are conducted
to validate the proposed extended state observer and tracking control
scheme with disturbance rejection. The proposed extended state observer
is compared with other existing research to show its supremacy.
Revisiting an ecophysiological oddity: hydathode-mediated foliar water uptake in Crassula species from southern Africa
Authors: Fradera-Soler Marc , Mravec Jozef , Schulz Alexander , Taboryski Rafael , Jørgensen Bodil , Grace Olwen
Published: June 2023

Hydathodes are usually associated with water exudation in plants.
However, foliar water uptake (FWU) through the hydathodes has long been
suspected in the leaf-succulent genus Crassula (Crassulaceae), a
highly diverse group in southern Africa, and, to our knowledge, no
empirical observations exist in the literature that unequivocally link
FWU to hydathodes in this genus. FWU is expected to be particularly
beneficial on the arid western side of southern Africa, where up to 50%
of Crassula species occur and where periodically high air
humidity leads to fog and/or dew formation. To investigate if FWU is
operational in different Crassula species we used the apoplastic
fluorescent tracer Lucifer Yellow in combination with different imaging
techniques. Our images of dye-treated leaves confirm that
hydathode-mediated FWU does indeed occur in Crassula and that it
is probably widespread across the genus. Hydathodes in Crassula
have been repurposed as moisture-harvesting structures, besides their
more common purpose of guttation, an adaptation that has likely played
an important role in the evolutionary history of the genus. Our
observations suggest that FWU ability is independent of geographical
distribution and its associated environmental conditions, as FWU is
possible in species occurring within the fog belt of western southern
Africa but also in those from the rather humid eastern side. We did not
find a strong apparent link between FWU ability and leaf surface
wettability. Instead, the hierarchically sculptured leaf surfaces of
several Crassula species may facilitate FWU due to hydrophilic
leaf surface microdomains, even in seemingly hydrophobic species.
Overall, these results confirm the ecophysiological relevance of FWU in
Crassula and reassert the importance of atmospheric humidity for
some arid-adapted plant groups.
Melatonin biosynthesis gene MdASMT9 confers tolerance to nitrogen deficiency in an MdHY5-dependent manner in apple plants
Authors: 里 赵 , Gao Tengteng , Liu Xiaomin , Zhang Danni , Tan Kexin , Zhou Yi , Jia Xumei , Zhang Zhijun , Ma Fengwang
Published: June 2023

Nitrogen (N) is a vital nutrient for crop growth and development which
influences both yield and quality. Melatonin (MT), a known enhancer of
abiotic stress tolerance, has been extensively studies; however, its
relationship with nutrient stress, particularly N, and the underlying
regulatory mechanisms of MT on N uptake remain unclear. In this study,
exogenous MT treatment was found to improve the tolerance of apple
plants to N deficiency. Apple plants overexpressing the MT biosynthetic
gene N-acetylserotonin methyltransferase 9 ( MdASMT9) was used to
further investigated the effects of endogenous MT on low-N stress. The
overexpression of MdASMT9 improved the light harvesting and heat
transfer capability of apple plants, thereby mitigating the detrimental
effects of N deficiency on the photosynthetic system. Proteomic and
physiological data analyses indicated that MdASMT9 overexpression
enhanced the trichloroacetic acid (TCA) cycle and positively modulated
amino acid metabolism to counteract N-deficiency stress. Additionally,
both exogenous and endogenous MT promoted the transcription of
MdHY5, which in turn bound to the MdNRT2.1 and
MdNRT2.4 promoters and activated their expression. Notably,
MT-mediated promotion of MdNRT2.1 and MdNRT2.4 expression
in an MdHY5-dependent manner, ultimately enhancing N absorption.
Taken together, these results may provide useful insights into the
relationship between MdASMT9-mediated MT biosynthesis and N
uptake under N-deficiency conditions in apple plants.

45.9% girls) patients received chemotherapy over 265 visits (85
single-day, 56 blocks). Inpatient sessions were more frequently of high
emetogenicity (47.8% of 138 sessions) and most daycare sessions
moderately emetogenic (79.5% of 127). Overall CC was 65.7%,
significantly better for inpatients (73.2%, P<.009) and for
sessions with weight-appropriate ondansetron dosing (p = 0.033). Odds of
experiencing nausea (median severity 4) were higher in day care (OR
2.11, 95% CI 1.13-3.92) and lower (OR 0.25, 95% CI 0.09-0.72) when
ondansetron dosing was weight-appropriate. CC did not vary significantly
with age or gender. Conclusion: The overall CC rate was 65%, and was
significantly higher for inpatients, highly emetogenic regimens, and
when appropriate ondansetron dosing was used. This study identified gaps
in our antiemetic practice, with moderately emetogenic sessions failing
to receive guideline-recommended antiemetics, correlating with
significantly lower complete control for daycare sessions.
Adjuvant immune checkpoint inhibitor therapy may benefit pediatric patients with stage III melanoma and sentinel lymph node positivity: a Case Series
Authors: Bowden Acacia , Zambito Jeanette , El-Feghaly Jinia , Andolina Jeffrey
Published: June 2023

Background: Melanoma is the most common skin cancer in
children. While the current literature establishes treatment protocols
for adult-type melanoma, very few pediatric-specific studies exist, and
children are often excluded from melanoma clinical trials
. Case Report: We report a case series of 23
consecutive pediatric patients diagnosed with melanoma at the University
of Rochester Medical Center between 1/1/2011 and 1/1/2022. 2/23 (8.7%)
patients had recurrence of their malignancy after therapy while 21/23
(91.3%) remained without disease progression; 1 patient died from
unknown cause, but the rest are alive and currently without disease. All
patients whose initial therapy included nivolumab in addition to wide
local excision did not have recurrence or progression of their disease.
Conclusions: This case series highlights trends in the
presentation, treatment, and outcomes of pediatric melanoma; however,
additional multi-center studies are needed to establish the clinical
utility of such features in pediatric melanoma.
“How are you getting on?”
Authors: McDonnell Karolyn
Published: June 2023

This research evaluates the use of asynchronous online discussion boards in assessment of work-based placement in a social care degree programme. Owing to a scarcity of educational technologies in the programme at the time (pre-COVID), discussion boards were introduced in a pilot endeavour to assess students' reflections on placement experiences. Individualised feedback was pledged from the programme instructors with a view to enhancing their reflective skills and their engagement with their work placement.

Staff and learners’ attitudes and experiences were investigated to identify the effectiveness of using discussion boards for work-based placement. The components of discussion boards for this purpose are identified, and the considerations to be made when implementing discussion boards to support the development of reflection skills are presented.

Using a mixed methods sequential complementarity research design, two student focus groups were held following the distribution of an online survey. Four staff instructors were interviewed about their experiences of and attitudes towards the experience. Finally, a hybrid code adapted from Henri’s (1992) computer mediated conferencing framework and Kolb’s (1984) learning cycle was created to analyse the reflectivity and interactivity in the group discussions.

Whilst discussion boards are useful as a digital platform to foster collaboration and discursive activities, in practice this assessment as delivered fell short of maximising their efficacy. Despite this, four components of discussion boards were identified and key considerations when using discussion boards to encourage reflective activity in social care work-based placement are proposed and discussed.

Published: June 2023

This study examines the operating pressure effect on the manufacture of biodiesel from Palm Kernel Fatty Acid Distillate (PKFAD) by using para-Toluene Sulfonic Acid (PTSA) catalyst. The operating pressures studied are the vacuum pressures of 70 kPa, 80 kPa, 90 kPa, and 100 kPa, which varied with PTSA concentrations of 5%, 10%, 15%, 20%, and 25%, and the molar ratios of methanol and PKFAD are 5:1, 6:1, 7:1, 8:1, 9:1, and 10:1. Biodiesel production from PKFAD was carried out with reaction duration of 120 minutes and reaction temperature at 50 0C. The amounts of fatty acids converted to biodiesel were calculated based on the initial and acid numbers after the esterification reaction. The results show that a vacuum pressure of 70 kPa to 100 kPa provides a conversion above 96% for all catalyst concentrations and all methanol and PKFAD molar ratios. The highest conversion of PKFAD to biodiesel of 98.6% is obtained at an operating pressure of 80 kPa, a catalyst concentration of 25%, and the molar ratio of methanol and PKFAD is 10:1. The biodiesel characteristics obtained in this study have met the standards of the American Society for Testing Materials.
Death and suicide in ethnographic field: The case of Buell H. Quain
Authors: Gorunovic Gordana
Published: June 2023

The immediate reason for writing this article is the novel Nine Nights by the Brazilian writer Bernardo Carvalho, and the subject is the thematization of anthropological thanatography and suicidology on the example of writing about the death of the forgotten anthropologist Buell Quain among the Brazilian Indians. The story of his anthropological work and suicide, once a taboo topic in the discipline, forms an integral part of a significant, but lesser-known episode in the history of American and Brazilian anthropology in the first half of the 20th century. The literary work in question is treated as one of the heuristic sources for the reconstruction of Quaine?s biography and ethnography and the anthropological-historical analysis of the case, and not as an analytical subject in itself. The anthropological understanding and interpretation of the ethnographer?s suicide in the field includes a number of interrelated subjective and objective factors: the idiosyncratic life history, the very nature and conditions of ethnographic research, the actual condition of the studied Indian communities, and the political climate in Brazil on the eve of World War II.

Published: June 2023

Background and purpose: Whether or not to resurface the patella during primary total knee arthroplasty (TKA) remains controversial. We aimed to investigate the association between patellar resurfacing and patient-reported outcome measure (PROM) improvement 1 year postoperatively in terms of physical functioning and pain following TKA.Patients and methods: We performed an observational study using the Dutch Arthroplasty Register on prospectively collected PROM data (n = 17,224, years 2014–2019). Preoperative and 1-year PROM pain scores (NRS at rest; during activity) and physical functioning scores (KOOS-PS, OKS) were examined. Stratification was performed for cruciate-retaining (CR) and posterior-stabilized (PS) and for the 4 most frequently used TKA implants in the Netherlands (Nexgen, Genesis II, PFC/Sigma, Vanguard) using multivariable linear regression adjusting for age, ASA classification, preoperative general health (EQ VAS), and preoperative PROMs.Results: 4,525 resurfaced and 12,699 unresurfaced patellae in TKA were analyzed. Overall, no significant difference in 1-year PROM improvement was found between the 2 groups. In CR TKAs, resurfacing resulted in less improvement in KOOS-PS and OKS (adjusted difference between groups (B) –1.68, 95% confidence interval (CI) –2.86 to –0.50 and B –0.94, CI –1.57 to –0.31. Fewer improvements for patellar resurfacing in TKA were found for the Genesis TKA on NRS pain at rest (B –0.23, CI–0.40 to –0.06) and Oxford knee score (B –1.61, CI –2.24 to –0.98).Conclusion: No significant differences were found in 1-year improvement of physical functioning and pain between TKA with resurfaced and unresurfaced patellae.

Published: June 2023

La tutoría académica se ha considerado una herramienta pertinente para lograr el egreso oportuno de los estudiantes, disminuyendo así la deserción escolar. Sin embargo, en las últimas generaciones del posgrado en estudio, el egreso no ha sido oportuno. Por lo tanto, resulta necesario evaluar el proceso tutorial del programa para trabajar en la mejora continua del acompañamiento del estudiante. Para ello, se realizó una investigación con enfoque mixto, de tipo documental, descriptiva, explicativa y correlacional. A partir del análisis de diversas fuentes especializadas en el tema, se caracterizó la problemática e identificaron las causas de esta. Asimismo, se midió el grado de relación entre las dimensiones y variables; y se aplicaron los métodos de juicio de expertos y Alfa de Cronbach para la validez del instrumento. Posterior al análisis cuantitativo, se procedió al cualitativo. Los resultados permiten visualizar un seguimiento constante y oportuno respecto a la trayectoria escolar. Sin embargo, se aprecia la falta de planeación entre el tutor y el tutorado, acorde a las necesidades propias de cada estudiante para el mejor aprovechamiento escolar. Asimismo, los análisis correlacionales determinan una relación considerable entre las dimensiones resultantes del proceso de operacionalización. Por lo anterior, es posible concluir que las tutorías académicas, de acuerdo a la percepción de los estudiantes, resultan un apoyo real a su trayectoria y egreso. De no impartirse correctamente, esto puede verse reflejado de forma negativa en el proceso de titulación y en el rebase de los tiempos establecidos para la misma.
