Authors: Benelli Alessandro , Cevoli Chiara , Fabbri Angelo , Ragni Luigi
Published: August 2022

The fruit industry needs rapid and non-destructive techniques to evaluate the quality of the products in the field and during the post-harvest phase. The soluble solids content (SSC), in terms of °Brix, and the flesh firmness (FF) are typical parameters used to measure fruit quality and maturity state. Hyperspectral imaging (HSI) is a powerful technique that combines image analysis and infrared spectroscopy. This study aimed to evaluate the potential of the application of the Vis/NIR push-broom hyperspectral imaging (400 to 1000 nm) to predict the firmness and the °Brix in apricots (180 samples) during storage (11 days). Partial least squares (PLS) and artificial neural networks (ANN) were used to develop predictive models. For the PLS, R2 values (test set) up to 0.85 (RMSEP=1.64 N) and 0.72 (RMSEP=0.51 °Brix) were obtained for the FF and SSC, respectively. Concerning the ANN, the best results in the test set were achieved for the FF (R2=0.85, RMSEP=1.50 N). The study showed the potential of the HSI technique as a non-destructive tool for measuring apricot quality even along the whole supply chain.
Best practices in post-flood surveys: The study case of Pioverna torrent
Authors: Cislaghi Alessio , Bischetti Gian Battista
Published: August 2022

Floods cause fatalities and considerable economic damage to infrastructures and settlements, besides impacting fluvial-geomorphic landforms. The increase in the frequency and magnitude of flood events has contributed to inevitably gaining public concern over the flood risk and awareness of the necessity to improve forecasting and monitoring streamflows. In this context, an efficient and systematic procedure of post-event surveys that documents the impacts of a flood event over the territory is often missing. Flood areas delimitation, erosion-sediment variation, and riparian vegetation change are often neglected. The present study shows the field- and desk-based post-flood surveys conducted after an extreme event occurred on June 12th, 2019, along the Pioverna torrent in Valsassina (North Italy). The post-flood surveys consist in collecting meteorological data and time-series satellite images to detect the land cover change (identifying areas covered by water, sediments, and vegetation), and in planning, a few weeks later, an unmanned aerial vehicle (UAV)-based survey to observe the riverbed and streambank change and the modifications in vegetation patterns through high-resolution derived-topographic data. The results show accurate maps of a ground classification from satellite-based elaboration and high-resolution digital elevation models from UAV-based surveys that can support restoration activities and the design of effective countermeasures. This practical application is appropriate and suitable as a river management strategy regarding timing, resources, and economic costs. Thus, standardising the procedure could be essential for creating a historical database, useful to improve specific guidelines and postemergency management strategies.
Portable central baffle flume
Authors: Bijankhan Mohammad , Teymourkhani Ali , Ferro Vito
Published: August 2022

This paper investigated the hydraulic characteristics of the triangular central baffle (TCB) flume. Laboratory tests were carried out to determine the flume dimensions. The field applicability of the proposed portable device was examined by on-farm installation. According to the laboratory tests, when the contraction ratio, r, was less than 0.39, the flow capacity was not affected by the ratio between the flume’s floor height and the throat width. The laboratory analysis also showed that there was no significant effect of installing an entrance ramp on the stage-discharge relationship for r<0.39, while the entrance ramp increased the discharge capacity for r>0.39. The stage-discharge curve obtained based on the laboratory tests was verified using field data. The results revealed that the proposed portable flume could be used accurately to determine the flow through an unlined ditch. Practical suggestions were proposed to determine the distinguishing condition curve.

Authors: Shawky El-Sayed Ahmed , Said Mosaad Ibrahim
Published: August 2022

This study aimed to evaluate a new prototype for an injection machine that works in sandy soils using treated cardboard waste. The tests were divided into three major categories: The first one was a performance evaluation of the new injection prototype. Secondly, study the effect of adding the treated cardboard to the sandy subsoil on reducing the irrigation levels and increasing the moisture content in the root zone of cultivated plants. As well, investigate sandy soil water storage efficiency and its impact on improving the soil’s properties. Thirdly, measurements on water-sensitive crop yields, like potatoes. The new prototype technique was designed based on using an automatic control system that is integrated to precisely control the injection discharge rate. So, the injection operation is proportionally synchronized with the tractor's forward speed. The field experiments were carried out at 0.24, 0.40, 0.57 and 0.74 m sec-1 of tractor forward speeds with 250, 350 and 450 mm of furrow openers' subsoil depths at 140 and 200 mm of injection widths and 5 and 10% concentrations of cardboard solution. The main results indicated that the maximal consumed energy was 196.08 kWh ha-1 with a field efficiency of 89.05% and an optimal field capacity of 0.281 ha h-1 using the highest variable levels. In addition, the water saving percentage was 35.80%, while the water storage efficiency was 85.85%. Furthermore, the total economic costs were reduced by 13.88% compared to the traditional silt injection method for the tested control plots.

Polymeric materials are largely used in horticulture for mulching and irrigation, but their long degradation time causes various environmental and agronomic problems, hence should be removed at the end of the crop cycle. Among different mechanized techniques for collecting polymer residues from the field, the single-phase one is the most effective, since the plastic film and irrigation tape lifting, cleaning, and collection operations are done in a single pass, though, in most cases, the implements used in Kazakhstan still need an operator to manage the winding mechanism.  The authors, who developed a completely automatic plastic retriever, based on a hydraulic drive with a friction clutch for winding up the plastic materials, assessed the power need of the implement, in order to compare it with the power need of similar implements, where the winding mechanism is hand-operated and consequently power consumption is high, due to the need to stop and start the engine many times.  In this study the parameters of the hydraulic drive were determined by analytical calculation, starting from pressure and speed data measured on the hydraulic line and velocity and traction resistance of the implemented measured during the field tests. The maximum power need to drive the winding mechanisms resulted 1.86 kW at a forward speed of the unit of 1.8 m⋅s-1. Secondary the operation costs were broadly assessed, finding that they were about 43% less then when using man driven equipment.

Published: August 2022

Microorganisms in soils are responsible for many ecosystem services. However, in degraded soils microbial abundance and function are limited which compromises several biologically facilitated processes. Inoculating soils with desirable microbes can help to re-instate or initiate a viable functioning microbial community. However, establishment success is reliant on the survival of the microorganism in an adverse environment. In this proof-of-concept study, artificial microbial refugia have been developed using resin and light-emitting diode array (LED) 3D printing technology. We assessed whether the artificial refugia, termed a Rhiome, would support better microbial growth in degraded soils. Soil compaction, a form of soil degradation, and Rhizobium, an important microorganism for global agriculture, were both selected as the use case application for this assessment. Different materials together with resin were assessed for their suitability as a 3D printing material and for supporting rhizobial growth. The best result was found in materials constructed with a combination of polylactic acid (PLA) resin, yeast extract and mannitol. In a soil compaction experiment with inoculation of rhizobia, the addition of Rhiome significantly increased bacterium survival in the compacted soil to a level similar to, or higher than, the rhizobial loading in non-compacted soils. Augmentation of the resin with yeast extract and mannitol increased Rhizobium growth significantly compared with the Rhiome constructed only with resin. These results indicate that the Rhiome was highly beneficial for instigating and maintaining significant rhizobia survival and growth in compacted soils. Further work, including near-to-field assessments, are required to assess Rhiome performance in a range of applications and to refine material properties relative to important context-specific performance metrics such as degradation rate. We propose the Rhiome concept as a promising asset in the toolbox for soil ecological restoration as a means of improving soil resiliency.
A review of anthropogenic stressors on Lake Sevan, Armenia
Authors: Gabrielyan Bardukh , Khosrovyan Alla , Schultze Martin
Published: August 2022

The resilience of natural systems may be severely compromised by anthropogenic influences. In this paper, the principal anthropogenic influences on the ecosystem of the Armenian highland lake Sevan during the past century are identified. The diversity and severity of the pressures were influenced by national priorities and the catchment's growth. Changes in the lake's morphometry and the littoral's morphology, as well as unsustainable usage of the lake's fish resources, were among the repercussions. They are discussed depending on how each sort of disturbance affects the ecosystem. Although the timing and degree of each stressor were specified, identifying the direct effects of each stressor was often challenging. The current management decisions and future threats to the lake's ecosystem are discussed. This article describes the history of the anthropogenic change of Lake Sevan and, using it as an example, assesses the ecological footprint of people on natural resources and their repercussions.

Published: August 2022

Over the past three decades, the Rideau River (Ontario, Canada) watershed has experienced a land-use change from rural and agricultural land towards urban land, and the introduction and expansion of invasive species. This study examined spatial and temporal patterns of periphyton biomass (chlorophyll-a and ash-free dry mass) collected from riffle zones in 1995 and 2019 along a 66-km stretch of the Rideau River. This study also examined long-term changes in water nutrient and chloride concentrations collected through the Provincial Water Quality Monitoring Network between 2000 and 2018. Declines in total nitrogen between 2000 and 2018 occurred in areas that have not experienced urbanization since the 2000s. In contrast, declines in total phosphorus and increases in chloride between 2000 and 2018 occurred at midstream and downstream sites that have undergone urbanization during the same time period. Conductivity also showed an increase with distance downstream similarly in both 1995 and 2019. Average total phosphorus and total Kjeldahl nitrogen concentrations were lower in 2019 compared to 1995 but did not increase with distance downstream as seen in many river systems, including the Rideau River, in earlier years. Periphyton biomass did not change along the length of the river between 1995 and 2019, despite the declines in nutrient concentrations. These findings highlight the persistence of riverine periphyton in a multi-use watershed experiencing ongoing anthropogenic changes.

Published: August 2022

This study aims to answer the following research question: what are the problems and prospects of the development of Islamic psychology studies in Southeast Asia? This study used descriptive qualitative research and employs data triangulation during data collection. Documentation study, in-depth interviews and focus group discussions were used to obtain the data. Data were analysed using patterns of data collection, data reduction, data presentation and conclusion drawing. It can be concluded that Islamic psychology presents many problems and prospects for those who are concerned about the development of Islamic science. The finding strengthens the perspective that there are three problems of developmental studies of Islamic psychology in Southeast Asia: (1) the discussion on the issue still focuses on theoretical integration and philosophical levels rather than on applicative ones; (2) methodological problems; and (3) polarisation of the capacity of Muslim psychologists. Apart from the problems, the development of Islamic psychology studies has good prospects. This indication can be seen from the following transformations: (1) from the formulation phase towards the research phase, (2) from comparative study patterns towards developing concepts of psychology based on Islam and (3) from a normative-cognitive approach towards the substantive-Sufistic approach.Contribution: Through this study, it is hoped that strategic attempts will be made by Muslim psychologists to collaborate and develop networks on designing more targeted studies in solving the various problems that arise around the integration of psychology and Islam at the ontological, epistemological or axiological levels.
Distinguishing trans women in men who have sex with men populations and their health access in East Africa: A Tanzanian study
Authors: Kashiha John , Ross Michael , Rider Nic
Published: August 2022

Background: Few data are available on the presence and characteristics of transgender populations in sub-Saharan Africa (SSA), which makes the provision of health services for key populations difficult.Aim: This study aimed to ascertain the presence and characteristics of trans women in seven cities in Tanzania, East Africa.Setting: Tanzania, East Africa.Methods: Outreach to men who have sex with men (MSM) in seven large cities in Tanzania was carried out by non-governmental organisation (NGO) staff familiar with this community. Survey questions administered via interviews were used to identify participants who self-identify as trans. From the self-identification data, an estimate of the relative size of the trans women population in this sample was calculated.Results: In the sample of 300 participants, 17.0% of participants were identified as ‘transsexual or transgender’ (survey wording); 70.1% of these trans participants indicated that they identify themselves as a woman. Of those identifying themselves as transsexual or transgender, 43.1% reported living part- or full-time as a woman and eight (15.0%) reported hormone use. The highest percentage of hormone use (40.0%) was found in those living as a woman full-time. Notably, there was significant ignorance amongst the sample of the terms ‘transsexual and transgender’ or their explanation in Swahili, reported by interviewers.Conclusion: In this study, it is clear that trans women populations exist in Tanzania, with high levels of stigmatisation and threats to their lives. They should be included in health outreach and services to key populations. One in six self-identified as trans women, although the lack of knowledge of this concept in Swahili or English may have inaccurately represented numbers.
‘All of a sudden, you know, you can’t go to these services, because of the risk of infection’: Audiological service considerations at residential care homes for older persons during COVID-19
Authors: De Andrade Victor , Landman Rethabile R.M.
Published: August 2022

Background: Residential care homes for older persons were especially affected during the coronavirus disease 2019 (COVID-19) pandemic lockdowns which resulted in limited social interactions and service provision. Communication became challenging due to the prophylactic use of masks and social distancing.Objectives: This qualitative research study set out to explore audiological service considerations in residential care homes for older persons during the COVID-19 restrictions.Method: Through purposive sampling, nine managers from residential care homes for older persons in Johannesburg participated in semi-structured, online interviews. The transcriptions of these recorded interviews underwent thematic analysis.Results: Managers employed various strategies to attend to residents’ audiological needs, audiological health, hearing aid use, and hearing aid provision. Furthermore, it transpired that other health related services were prioritised over audiological services in general, but especially during the pandemic lockdowns. Managers reported that staff had to use various communication strategies due to COVID-19 precautions and that masks and social distancing made communication more challenging for residents with hearing loss. Moreover, isolation and modified service provision were extremely taxing on residents.Conclusion: This study highlights the need for continued audiological services at residential care homes, but also the need to balance audiological needs with other health needs because these seem to be prioritised over hearing loss, especially in this population who may have limited agency and choice in the health care options available to them. Furthermore, adapted strategies need to be considered to support communication considering COVID-19 precautions so that communicative difficulties do not exacerbate lockdown isolation.

Published: August 2022

Seismic loading has always been a major concern for any engineering structures, and thereby, underground facilities (e.g., tunnels) are not exceptional. It is due to the seismically induced uplift and instability of tunnels caused by the large deformation of liquefiable soils. Therefore, the tunnel uplift behaviors subjected to seismic loading are always taken into account in any designing stages of tunnels. This study's main goal was to evaluate how a tunnel buried in liquefiable and non-liquefiable soils would behave when subjected to seismic stress. Seismic and liquefaction potential assessments of the soils surrounding the tunnel were carried out using the finite-element method. In this study, PM4sand, an advanced constitutive model was adopted in all finite-element models. In addition, the uplift displacement and excess pore pressure of liquefiable soils were studied, under a typical earthquake. Investigations were also conducted into how the thickness of the non-liquefiable soil affected seismic loading, tunnel uplift displacement, and the buildup of excess pore water pressure. As a result, during the earthquake, liquefaction was triggered in most parts of the sand layer but not in the clay layer. In addition, the tunnel uplift displacement was triggered due to the relative motion and interaction at both sides of the tunnel. In addition, this study found that the thickness of the non-liquefiable soil layer (sand layer) had a significant impact on the build-up of excess pore water pressure and, consequently, the tunnel uplift displacement. The uplift displacement and excess pore water pressure build-up were higher the thinner the non-liquefiable layer was.

Published: August 2022

Placement of infrastructure and other facilities underground brings superior opportunities for long-term improvements in terms of the environmental impact of urban areas and more efficient use of underground space. However, underground construction in urban areas is a high-risk activity and has been considered a challenging problem for geotechnical and structural designers. Therefore, the evaluation of the stability of underground structures plays a vital role in structural and construction design. This paper presents a case study on analyzing the stability of steel piles walls and tunnels excavated by shield machines in the urban area in Vietnam in terms of the change in internal forces in the structures. The research results show that the excavated stages of the basement influence on the values of internal force in the tunnel lining. In the case of study using composite lining in the tunnel, the thickness of lining concrete 35 cm, steel frame type I-W1000×883 are applied for tunnel excavated before construction of nearby basement, and 30 cm and W1000×350 steel ribs for the opposite side. This research could be applied to evaluate the effects of tunnel excavation near the existing structures in urban such as in the geological conditions in the Ha Noi and Ho Chi Minh City in the near future. However, this analysis also has the disadvantage that it does not consider the construction time as well as the construction sequence of the works during tunnel excavation. The shapes of the tunnel only are circular tunnels and the only type of steel piles in this research. Further study, total evaluation for other types of tunnels and walls of basements should be considered.
Stability analysis when tunnelling in soft soil condition in Hochiminh city
Authors: Vu Ngan Minh ,   Faculty of Civil Engineering, Hanoi University of Mining and Geology, Vietnam
Published: August 2022

The rapid development in the economy and the urban population in cities in Vietnam in recent years leads to dramatic growth in traffic congestion, noise and air pollution, and environmental degradation. Urban underground infrastructure thus becomes an inevitable solution since the surface space becomes too expensive and restricted in spite of the high cost of tunnel construction. However, tunnelling in deltaic urban areas, in particular in the cases of Mekong Delta and Red River Delta areas, often faces to difficulties of soft soil conditions and the existence of important historical buildings on the surface. The first metro line constructed in Vietnam from Ben Thanh to Suoi Tien, which is located under crowded areas of Hochiminh city, was tunnelled in such conditions. This paper presents a back analysis for the stability of the tunnelling process in the project. The minimum support pressures is estimated by using the wedge model proposed by Jancsecz, S., & Steiner, W. (1994). Meanwhile, the maximum support pressure is estimated by the blow-out model proposed by Vu et al. (2016). Based on these results, the range of support pressures recommended for the Earth Pressure Balance Tunnel Boring Machine in the Hochiminh Metro Line No.1 project soft soil conditions is derived and compared to in situ support pressures obtained from the monitoring data in this tunnelling project. The study result shows a good agreement between the support pressures obtained from stability analysis models and the monitoring data from the construction site. Based on this back analysis, some recommendations are proposed with the purpose of successful construction in the next tunnelling projects in Hochiminh city.

Authors: Dang Thanh Trung , Tran Minh Tuan , Nguyen Hiep Huy ,   Faculty of Civil Engineering, Hanoi University of Mining and Geology, Vietnam  Military Technical Academy, Vietnam
Published: August 2022

Ground Characteristic Curve (GCC) describes the relationship between the initial stress of rock mass and the displacement of rock mass on the boundary of tunnels. Another way that indicates the relationship of support pressure and the level of Convergence Confinement of tunnels by percent. The using GCC to design supports in the underground construction has many advantages to ensure full utilization of the loading bearing capacity of rock mass, and release a part of initial stress in the rock mass around tunnels. However, this method is limited in the field of underground mines in Viet Nam. This article analyzed and applied GCC and Convergence Confinement Method (CCM) to design the supports of underground constructions and applied them to the geological conditions of the Nam Mau coal mine - Vinacomin. The research results show that at the geological conditions of the drift at level +125 in Nam Mau coal mine, TH section steel ribs with flange width 124 mm, section depth 108 mm, weight 21 kg/m, maximum support pressure 1.98 MPa, and spacing 700 mm were applied. Results of research in this method can be applied to design rock supports for deep roadways and other drifts in the underground mines in Quang Ninh province of Viet Nam. By a factor of safety, mobilized support pressure, wall displacement of roadways, and convergence of roadways the designation and selection of rock support around roadways will become clearer. Near future this method should be widely applied in the combined protection design in deep roadways in underground mines in Viet Nam. Although the method has great advantages, it is still necessary to have complete and detailed monitoring data of the geological and hydrogeological conditions in the area under consideration.

Authors: Yulianto Auw Tammy , Simon Simon , Cahyadi Tjiong Eric
Published: August 2022

Feng shui was a part of the cultural heritage of ancient Chinese society mainly used to design buildings and spaces according to the birth date or the basic elements of the owner or the person who occupied a building to achieve harmony and balance with the environment aimed to bring peace and prosperity. Feng shui practices had become a matter of debate among Christians. The question was whether feng shui practices such as calculations in building construction, determining the direction a tomb should face, or finding a date to start a business did not conflict with God's Word. From a non-theological point of view,  feng shui was well accepted because it seemed reasonable. This article discussed feng shui from a theological perspective by referring to Colossians 2:8. In the research of this article, the researchers used a qualitative descriptive method with an exposition approach where data collection was obtained from literature studies and interviews. The results of the discussion on this topic showed that theologians concurred that feng shui did not correspond with God's Word, while the Bible interpreted feng shui as a false philosophy. The conclusion drawn was the rejection of feng shui practices by theologians and the Bible.

Published: August 2022

The fuzzy-based approach was chosen because fuzzy logic enables computerization of human reasoning. In recent years, Forecast accuracy and applicability to success in general. Models that show as fuzzy were developed. Data that are difficult to collect with exceptional predictive accuracy can be developed by utilizing the experience of fuzzy logic based models. One of the basic conditions necessary for a person to continue his life in a healthy way is to keep the body temperature at a normal temperature. Thermal comfort means that the majority of the workers in the working environment are in a certain comfort while continuing their physical and mental activities in terms of climatic conditions such as temperature, humidity and air flow rate. If the thermal comfort conditions are insufficient in the working environment, distress is felt and discomfort begins, and accordingly, the working capacity and work efficiency of the person decreases. In this article, temperature physiology and occupational health will be evaluated with fuzzy logic in weaving business. Recognition of risks in the work environment is the most important factor in preventing occupational disease, work-related illness and occupational accidents. The air flow velocity Va (m/s) read from the thermal micro air conditioner is a parameter related to how people in an environment perceive the environment in which the components of personal and environmental factors affecting thermal comfort are expressed mathematically, using PMV and PMV value. The index PPD change, which indicates the rate of change, was determined with the help of fuzzy logic.

A Study on Students’ Public Stigma of COVID-19 and Its Influencing Factors in The Context of The Long Term Handling of The COVID-19 Pandemic
Authors: Huang Lu , Liu Feng , Liu Bo
Published: August 2022

Objective: To understand the public stigma and associated factors of COVID-19 in Jingzhou adolescents relating to the prevention and containment of COVID-19 cases. Methods: From June to October 2021, an online survey was conducted in two junior high schools in Jingzhou City. A total of 2888 students participated in the survey, with 2800 being valid responses (effective rate 97.0%). The survey tools used the COVID-19 attitude questionnaire, and the related factors were analyzed by a stepwise multiple linear regression method. Results: 31.4% of the participants showed public stigma towards COVID-19, with a larger portion of those being in lower grades (P<0.01), only children (P<0.05), and those not quarantined during the outbreak (P<0.05). Multiple linear regression analyses showed higher levels of stress (P<0.01), lower levels of social support (P<0.05), younger age (P<0.01) and higher educational level of parents (P<0.05) during the pandemic correlated to stronger public stigma towards COVID-19. Conclusion: Participants' stigma of COVID-19 is widespread, and it is manifested in social isolation. The respondents’ level of stress and social support during the pandemic is shown to be linked to their degree of stigma. Methods for reducing this public stigma for COVID-19 may include stopping the spread of misinformation, providing psychological support, and alleviating negative emotions.

PEMBAGIAN HARTA ADAT DAN PROBLEMATIKA PEMBAGIAN DI DESA TAMMANGALLE KABUPATEN POLEWALI MANDAR SULAWESI BARAT
Authors: Aminuddin Aminuddin , Emy Emy , Sahdi Nur
Published: August 2022

Tujuan penelitian ini adalah mengungkapkan pembagian harta adat dan problematika pembagian di desa Tammangalle, kecamatan Balanipa, Kabupaten Polewali Mandar. Adapun jenis penelitian ini adalah deskriptif kualitatif. Jenis data yang digunakan dalam penelitian ini adalah data primer. Data primer adalah yang diperoleh secara langsung dari narasumber di lokasi penelitian, berupa wawancara langsung terhadap masyarakat setempat. Adapun hasil penelitian yang didapatkan bahwa Pembagian warisan di Desa Tammangalle sejatinya sudah sejalan dengan syariat Islam karena laki-laki mendapatkan dua sedangkan perempuan mendapatkan satu. Alasan ini didasari karena tanggung jawab anak laki-laki lebih berat dari pada anak perempuan, seperti tanggungan terhadap kebutuhan anak, istrinya, dan kerabat. Sementara anak perempuan sebelum ia menikah semua kebutuhan pada dirinya ditanggung oleh orang tua atau walinya. Tetapi, jika ia sudah menikah, maka tanggung jawab tersebut berganti dan dibebankan kepada suaminya yang menjadi kepala keluarga. Kenyataannya pula di desa Tammagelle sekalipun sejalan dengan ajaran Islam tetapi masih ditemukan permasalahan yang kerap timbul seperti hukum wasiat yang dilakukan, berupa ucapan lisan di hadapan saksi wasiat yang ditujukan kepada anak angkat jika ada atau “Ucapan Lisan” yang secara praktiknya belum memenuhi standar keabsahan suatu pernyataan.

Spatio-Temporal Analysis of Land Use Land Cover, Dynamics in Built-up Area and Its Trend Predictions in Peshawar Vale, Pakistan
Authors: Ali Sajjad , Rahman Atta Ur , Ali Sher
Published: August 2022

This study focused on the Spatio-temporal monitoring of land use land cover, built-up area, its trend, and its prediction in the valley of Peshawar, Pakistan. The collected data from 1990 to 2020 were spatiotemporally analyzed in GIS to get the required objective. Parallel to this, Terr-Set has been used for change analysis, whereas Cellular Automaton and Markov model have been applied for trend prediction of built-up area for 2050. The land use land cover analysis indicates that the study area's built-up area is rapidly increasing. The land use land cover statistics reveal that, the built-up area and vegetation cover showed a positive growth trend as the area under the built environment and vegetation cover consistently increased. However, the area under barren Land is decreasing with time, showing a negative trend. The analysis of the Markov model predicted that in 2050 the built-up area in Peshawar valley would be further increased at the cost of consuming bare soil and vegetation cover.
La jurisdicción internacional directa en el Derecho Internacional Privado con especial referencia al Art. 57 de la ley 19.920
Authors: Ferreira Alejandro
Published: August 2022

La regulación de las situaciones privadas internacionales trae aparejado la determinación de tres presupuestos empíricos. El derecho sustantivo aplicable al caso, los tribunales que asumirán competencia y las reglas de continuidad jurídica de los fallos y laudos arbitrales, así como los diversos mecanismos de cooperación procesal civil o penal internacional. En este artículo analizaremos las nuevas bases de competencia internacional determinadas en la ley 19.920, en tanto que representaron una transformación sustantiva del panorama iusprivatista internacional. La derogación del Apéndice del Código Civil, en especial el art.2401 (que contenía dos criterios de jurisdicción bilateral), trajo consigo casi una veintena de criterios de base de jurisdicción directa, entre los que destacan la autonomía de la voluntad, el foro de necesidad, entre muchos otros parámetros sin antecedentes directos en el sistema de Derecho Internacional Privado de fuente convencional y autónomo preexistente. En este artículo abordamos las nuevas bases de competencia y los límites que se disponen a la luz del Derecho Internacional General.
¿Qué puede hacer el acreedor en el incidente de calificación del proceso concursal? ¿Es vinculante para el juez la calificación fortuita de la sindicatura o intervención?
Authors: Pereira Campos Santiago , Vera Pacaluk Micaela
Published: August 2022

En relación a la participación del acreedor denunciante en el incidente de calificación del concurso, la postura de nuestra jurisprudencia ha sido restrictiva limitando su participación a la mera denuncia de hechos relevantes para la calificación culpable. El presente trabajo tiene como objetivo analizar el rol del acreedor en el marco del incidente de calificación del proceso concursal a la luz de los principios pro actione y al control de convencionalidad. Asimismo, habrá de considerarse el impacto de la derogación introducida a los arts. 198 inciso final y 199 de la Ley 18.387, por el art. 652 de la Ley 19.355.
Biodegradation of Batik Wastewater: Study of isolation & characterization indigenous bacteria in Tulungagung, East Java Province, Indonesia

In fact, batik’s industry in Indonesia has increased its productivity by 14.7% at 2011 until 2015 according to Ministry Coordinator Welfare Field Republic of Indonesia . Increasing the batik productivity has an effect on the aquatic environment due to inappropriate disposal of wastewater. The wastewater changes the physical and chemical condition of the aquatic environment. The high presence of dyes in wastewater can cause pollution of aquatic environments. The dyes used in wastewater sample is naphthol and indigosol, which is known as a synthetic dye have stable molecules, and difficult to be degraded. This research was conducted to isolate, identify, characterize indigenous bacteria, and measurement their ability to decolorize dyes from Tulungagung’s batik waste water. The study site was used as sampling location on Kauman, Tulungagung district, East Java Province. To obtain bacteria with dyestuff degrading character, sample containing liquat waste and sedimen from the batik industry collected and cultured on Busnall Hass media enriched with dyes (naphtol and indigosol) and put into the shaker at 150 rpm for up to 6 days. Meanwhile, to grow fat degrading bacteria, the samples were cultured on BH media with the addition of olive oil. This mixture was conditioned on a shaker at 150 rpm for 5 days. After the propagation, the next step was to coat the culture on nutrient agar media, incubated at 37°C for 24 hours. This step aimed to obtain pure isolates which used for morphology and biochemistry test. The selected isolates were also identified based on 16S rRNA gene sequence homology methods. Each of isolated have a different ability to degrade the dyes and fats. From the four bacteria obtained, three isolated were selected that had the highest ability to degrade dyes in vitro namely:: Bacillus subtilis, Pseudomonas putida, and Enterobacter agglomerans. The results obtained in this study suggest that indigenous bacteria have the potential to remove dye and fat concentrations in batik industry wastewater.
