Legal Status of the Land of the Sultanate Special Region of Yogyakarta

Land within the territory of the Republic of Indonesia is one of the main natural resources and has a very strategic function in meeting the increasingly diverse needs of the state and its people. policies for managing control, ownership, and utilization of land as stipulated in Law Number 5 of 1960 concerning Basic Agrarian Regulations. The Special Region of Yogyakarta, as one of the regions that has privileges in carrying out its administration, is regulated by law. One of the privileges of the Special Region of Yogyakarta is the issue of land. In the Special Region of Yogyakarta, not all Indonesian citizens can obtain property rights as stipulated in the law. It's as if the regional government is discriminating against Indonesian citizens, especially non-Indigenous Indonesian citizens. With the Instruction of the Deputy Governor of the Special Region of Yogyakarta No. K.898/I/A/1975, it has become increasingly clear in the land polemic in the Special Region of Yogyakarta that there have been discriminatory actions in the land sector.

Filipinler'in Amerikan Kontrolü Döneminde (1898-1916) Osmanlı Filipinler İlişkileri

The present study attempts to investigate the resistance of Philippine people against Spanish rule in 1521 and American rule in 1898, along with their resistance against the colonialists in the Philippines, island country of Southeast Asia. Additionally, the attitude of the Ottoman Empire towards these controlled and Ottoman-Philippine relations will also be analyzed. The Philippines remained under Spanish rule for several centuries until the Americans arrived. Given that the geographical location of the Philippine islands is on one of the historically important trade route networks stretching from Europe to the Far East and the China Sea, these relations have become more crucial. During this period Captain John P. Finley, the U.S. governor of Zamboanga in the Philippines made a visit to Istanbul and tried to persuade the Ottoman administration that Muslims should not resist the American occupation by using the influence of the caliph on Muslims. The main resources of our research are based on the documents in the Presidential Ottoman Archives and their background. National and international research on the Philippines have also guided us through our research.

Positioning Portugal in the Context of World Almond Production and Research

Almond production plays a very significant role in the Portuguese socio-economic context, especially with regard to dried fruit production. Indeed, Portugal is the third largest almond producer in Europe, producing 41,450 t of almonds in shells in 2021. This is due to its edaphoclimatic conditions that are favorable for its production. Traditionally, the north region of “Trás-os-Montes” has stood out as one of the most relevant for Portuguese almond production and bioeconomy. However, production in “Alentejo“ and “Beira Interior” will surpass the northern region in a short time as a result of the installation of new orchards. Despite its importance, there is a need to uncover genetic traits underlying phenotypic desirable traits needed to improve yield and quality but also cope and mitigate the impacts of climate change on their production. To address this, it is important to characterize the genetic resources available and the germplasm collection since they are crucial players for conservation and breeding initiatives. In this review, we describe the main cultivars of almonds cultivated in Portugal and their productive challenges. We also provide an overview of the main genetic resources available, breeding goals, and accomplishments regarding their improvement towards biotic and abiotic constraints in both Portugal and the rest of the world.

Innovative high-pressure water scrubber for biogas upgrading at farm-scale using vacuum for water regeneration

Biogas upgrading is becoming essential in the valorization path for biogas. Biomethane from anaerobic digestion is identified to be one of the main resources to decarbonize the energy requirement. However, small-scale (especially farm-scale) applications suffer from a lack of implementation worldwide, mainly limited by the cost of the upgrading process. As one of the most used technologies, High Pressure Water Scrubbing presents a great margin for improvement. The most expansive items in this technology remain the packing column used for absorption and the stripping column used for water regeneration. In this work, the stripping column is replaced by a flash tank submitted to a rough vacuum (up to 0.2 bar in absolute pressure) associated to a static mixer to promote the gas desorption and thus the complete regeneration of the water. The implementation of an anisotropic packing, with properties evolving with the height of the column and adapted to the reduction of the gas flowrate due to absorption, is also investigated in order to reduce the size of the absorption column. A full-scale prototype was developed and implemented on a farm anaerobic digester. The range of application is from 20 to 40 Nm3/h of raw biogas. These field experiments associated to a complete description of the gas fluxes allowed to characterize the device in terms of carbon dioxide absorption efficiency, biomethane purity and methane recovery. Influences of six parameters (absorption pressure, desorption pressure, temperature, water flowrate, biogas flowrate, column height) were elucidated regarding those performances. Results highlight the great improvement of the water regeneration conducted under rough vacuum. From 0.8 to 0.2 bar in absolute pressure, the biomethane purity increased by 10%, the carbon dioxide elimination rate by 14%, and the methane recovery by 19%. With an increase in the packing height using an anisotropic configuration (modification of the packing properties with the column height) suited to the gas flowrate decrease into the column, a biomethane purity over 97% was obtained. The energy consumption associated was measured at 0.8 kWh/Nm3 of raw biogas but can be reduced to 0.3 kWh/Nm3. The overall energy efficiency for biogas upgrading can reach up to 91%. These results could pave the way for gas grid injection and vehicle fuel applications for small-scale anaerobic digestion.

Educational Quality of YouTube Videos for Patients Undergoing Elective Procedures

IntroductionYouTube has become a main resource used by patients for self-education on medicine. It is important for surgeons to understand the quality and reliability of videos that patients are likely to view about elective procedures. MethodsVideos were categorized by view count and content creators. The top 20 videos for each term, sorted by relevance, were evaluated using DISCERN criteria, a question set externally validated to assess the quality of information regarding health treatment choices. DISCERN score (DS) closer to 5 indicate higher quality information and 1 indicates the opposite. Total scores were given: 15-26 (very poor), 27-38 (poor), 39-50 (fair), 51-62 (very good), and 63-75 (excellent). Search terms included “Wound Care”, “Skin Grafting”, “Tracheostomy”, and “percutaneous endoscopic gastrostomy tube placement”. ResultsIn total, 80 unique videos were evaluated with a total view of 8,848,796. The mean overall DS was 2.15 and a mean bias DS was 2.46. The median DISCERN total score for each key term was Tracheostomy: 35 (poor), Skin Grafting 26 (very poor), percutaneous endoscopic gastrostomy: 32 (poor), and Wound Care: 40 (fair). ConclusionsYouTube videos surrounding elective procedures should be viewed cautiously in patient education despite wide availability. The videos in this study show high levels of bias and low DS. Healthcare providers should be aware of poor-quality consumer health information often disseminated in online media such as YouTube.

Features of morphometric characteristics of Artemia Leach, 1819 in lake Kulundinskoe, Altai territory in the period of desalination

The beginning of the study of the raw material base and features of the biology of the crustacean Artemia Leach, 1819 is associated with the prospect of using cysts as a starter food in aqua and sea culture. Food from Artemia cysts is used in the cultivation of 85% of marine organisms. Numerous hypersaline lakes of the Altai Territory are of particular interest for the industrial extraction (catch) of a valuable bioresource, the morphometric features of which, salinity and light regime provide a high level of their bioproductivity. This article presents the results of a morphometric study of the crustacean Artemia in the hypersaline lake Kulundinskoe for 2020–2021. Due to the increase in the general level of moisture in the territory, Lake Kulundinskoye tends to decrease in mineralization. In this regard, there are changes in the catch (production) of the main commercial resource — Artemia (at the stage of cysts), and the biota is replenished with brackish-water species. Under conditions of reduced water mineralization, crustaceans show a decrease in the values of morphometric parameters. By 2021, during the study, an increase in morphometric indicators was found due to an increase in mineralization from 70 to 90 g/l. Based on the studied main plastic (14) and meristic (2) features of the Artemia crustacean in the hyperhaline lake Kulundinskoe and using correlation analysis, the dependence of the parameters of morphometric measurements of female brine shrimp was studied. Desalination of Lake Kulundinskoe was observed in 2020–2021, in connection with which the biological numerical characteristics of the artemia branchiopods are given.

Long-Term Variability in Sea Surface Temperature and Chlorophyll a Concentration in the Gulf of California

The Gulf of California (GC) is the only interior sea in the Eastern Pacific Ocean and is the most important fishing area in the northwestern region of the Mexican Pacific. This study focuses on the oceanographic variability of the GC, including its southern portion, which is an area with a high flow of energy and exchange of properties with the Pacific Ocean (PO), in order to determine its role in physical–biological cycles and climate change. The purpose of this work is to analyze the sea surface temperature (SST) and chlorophyll a concentration (Chl-a) during the period from 1998–2022 as indicators of long-term physical and biological processes, oceanographic variability, and primary production in the GC. In total, 513 subareas in the GC were analyzed, and a cluster analysis was applied to identify similar areas in terms of SST and Chl-a via the K-means method and using the silhouette coefficient (>0.5) as a metric to validate the clusters obtained. The trends of the time series of both variables were analyzed, and a fast Fourier analysis was performed to evaluate cycles in the series. A descriptive analysis of the SST and Chl-a series showed that the SST decreased from south to north. Six bioregions were identified using a combined of both SST and Chl-a data. The spectral analysis of the SST showed that the main frequencies in the six bioregions were annual and interannual (3–7 years), and the frequencies of their variations were associated with basin-level weather events, such as El Niño and La Niña. The SST in the GC showed a heating trend at an annual rate of ~0.036 °C (~0.73 °C in 20 years) and a decrease in Chl-a at an annual rate of ~0.012 mg/m3 (~0.25 mg/m3 in 20 years), with potential consequences for communities and ecosystems. Additionally, cycles of 10–13 and 15–20 years were identified, and the 10–13-year cycle explained almost 40–50% of the signal power in some regions. Moreover, mesoscale features (eddies and filaments) were identified along the GC, and they were mainly associated with the clusters of the SST. All these spatial and temporal variabilities induce conditions that generate different habitats and could explain the high biodiversity of the GC. If the warming trend of the SST and the decreasing trend of the Chl-a continue in the long term, concerns could be raised, as they can have important effects on the dynamics of this important marine ecosystem, including habitat loss for numerous native species, declines in the catches of the main fishery resources, and, consequently, support for the arrival of harmful invasive species.

The Role of Georgetown Public Library in Meeting the Academic Information Needs of High School Learners

High school learners have various information needs crucial for the acquisition of knowledge and skills in preparing them for future academic progress. This study set out to investigate the role of Georgetown public library in meeting the academic information needs of high school learners. It established the nature of academic information sought by learners, ascertained the learners’ information-seeking behaviour and determined the ways Georgetown public library (in Pietermaritzburg, KwaZulu-Natal, South Africa) uses to meet the academic information needs of high school learners. A quantitative research approach was adopted, and the survey research design was used. Through a systematic sampling technique, the study randomly administered 291 questionnaires to high school learners in the Georgetown public library in the Edendale area. Data were analysed following a descriptive analysis method. The results of the study revealed that, among others, the nature of academic information needs of learners included information to perform various school projects; doing assignments; improving reading skills; obtaining information for tasks given by teachers; and gaining access to computers and space. Some learners were familiar with library operations and possessed limited skills; therefore, they sought information on their own. However, some sought assistance from and heavily relied on library staff for seeking information to satisfy their information uncertainty, and for help with computer usage. Books were the main resource of the library utilised by high school learners, although other resources such as encyclopaedias, magazines, newspapers, CDs, study guides, textbooks, and dictionaries were also used. The study concluded that most learners understood their information needs, although they used different ways to satisfy them. The availability of computers and assistance from the librarians were crucial for them to meet their academic information needs. The study recommends that Georgetown public library should be aware of the needs of Grade 10 high school learners and understand their information-seeking behaviour to assist with guidance, knowledge and computer skills.

Serine-associated one-carbon metabolic reprogramming: a new anti-cancer therapeutic strategy.

Tumour metabolism is a major focus of cancer research, and metabolic reprogramming is an important feature of malignant tumours. Serine is an important non-essential amino acid, which is a main resource of one-carbon units in tumours. Cancer cells proliferate more than normal cells and require more serine for proliferation. The cancer-related genes that are involved in serine metabolism also show changes corresponding to metabolic alterations. Here, we reviewed the serine-associated one-carbon metabolism and its potential as a target for anti-tumour therapeutic strategies.

Regional overview potential zones for groundwater recharge in Wadi Hodein, south Eastern Desert of Egypt

ABSTRACT Wadi Hodein (WH) is one of the largest arid wadies in the eastern desert, where the groundwater (GW) is the main water resource, to meet the water demand of its residents. Therefore, GW recharge (GWR) potential zones map is to be constructed as an effective tool for GW management in WH. Analytical hierarchy process (AHP) with geospatial analysis using ArcMap was used to delineate the GWR. Six thematic layers (soil map, slope, geology, geomorphology, lineament density, and drainage density) were used to produce the recharge map. The results classified the potential of WH recharging into five categories very low, low, moderate, high, and very high with their corresponding percentage areas of 2.60%, 9.30%, 42.9%, 31.30%, and 14.00%, respectively. Verification analysis using water quality data of the drilled wells inside the study area was conducted to confirm the resulted GWR potential map.

Irreversibility analysis through neural networking of the hybrid nanofluid for the solar collector optimization

Advanced techniques are used to enhance the efficiency of the energy assets and maximize the appliance efficiency of the main resources. In this view, in this study, the focus is paid to the solar collector to cover thermal radiation through optimization and enhance the performance of the solar panel. Hybrid nanofluids (HNFs) consist of a base liquid glycol (C3H8O2) in which nanoparticles of copper (Cu) and aluminum oxide (Al2O3) are doped as fillers. The flow of the stagnation point is considered in the presence of the Riga plate. The state of the solar thermal system is termed viva stagnation to control the additional heating through the flow variation in the collector loop. The inclusion of entropy generation and Bejan number formation are primarily conceived under the influence of physical parameters for energy optimization. The computational analysis is carried out utilizing the control volume finite element method (CVFEM), and Runge–Kutta 4 (RK-4) methods. (FEATool Multiphysics) software has been used to find the solution through (CVFEM). The results are further validated through a machine learning neural networking procedure, wherein the heat transfer rate is greatly upgraded with a variation of the nanoparticle's volume fraction. We expect this improvement to progress the stability of heat transfer in the solar power system.
