Variasi Temporal Karakteristik Arus di Perairan Tanjung Jati Kabupaten Jepara

The waters of Tanjung Jati, Jepara Regency, are quite strategic areas due to the utilization of the coastal areas and waters. One water parameter that is important to study and has a high enough influence on other parameters is ocean currents. The purpose of this study is to determine the characteristics of the ocean currents that occur in the waters of Tanjung Jati, by temporal variation in 2020 and 2021. The results show that the smallest current velocity is in the most basic layer; this is likely due to the influence of the friction force on the bottom of the water, while the greatest velocity is on the layer near the surface. Current characteristics show a relationship between current velocity, current direction, and water level that occurs in each layer of water. This relationship can be seen by the decrease in current velocity at the lowest tide and the highest tide, and vice versa. The current velocity increases at low tide. The highest optimal velocity at low tide towards tide compared to tidal currents towards ebb. The direction of this optimal current is northeast. The movement of the current at tide towards the ebb is towards the West - Southwest, while the current movement during the tide towards the tide is towards the East - Northeast direction. The direction of the dominant current that occurs in the waters of Tanjung Jati B, Jepara, is towards the East-Northeast domination at low tide and towards the West-Southwest domination at low tide. Details on the current characteristics of each layer in 2020 and 2021 have not changed significantly. Kawasan perairan Tanjung Jati Kabupaten Jepara merupakan Kawasan yang cukup strategis dikarenakan pemanfaatan wilayah pesisir maupun perairannya. Terkait hal tersebut, sal;ah satu parameter perairan yang penting untuk diteliti dan mempunyai pengaruh cukup tinggi terhadap parameter lainnya adalah arus laut. Tujuan penelitian ini adalah mengetahui karakteristik arus laut yang terjadi di perairan Tanjung Jati, secara variasi temporal tahun 2020 dan 2021. Hasil penelitian menunjukkan Kecepatan arus terkecil berada pada layer paling dasar hal ini kemungkinan terjadi karena pengaruh gaya gesek dengan dasar perairan, sedangkan kecepatan paling besar berada pada layer dekat permukaan. Karakteristik arus seperti yang terlihat menunjukan adanya hubungan antara kecepatan arus, arah arus dengan elevasi air yang terjadi pada setiap lapis air. Hubungan ini dapat dilihat dengan adanya penurunan kecepatan arus pada saat muka air surut terendah dan pasang tertinggi dan sebaliknya kecepatan arus meningkat pada saat pasang menuju surut. Kecepatan optimal tertinggi pada saat arus surut menuju pasang dibandingkan dengan arus pasang menuju surut. Arah arus optimal ini adalah timur laut. Pergerakan arus pada saat pasang menuju surut adalah ke arah Barat – Barat Daya sedangkan pergerakan arus pada saat surut menuju pasang adalah ke arah Timur – Timur Laut. Arah arus dominan yang terjadi di kawasan Perairan Tanjung Jati B, Jepara adalah ke arah dominasi Timur- Timur Laut pada saat surut menuju pasang dan ke arah dominasi Barat-Barat Daya pada saat air pasang menuju surut. Detil pada karakteristik arus tiap layer pada tahun 2020 dengan 2021 tidak mengalami perubahan secara signifikan.

Desiderata for a Synthetic Clinical Data Generator

The current movement in Medical Informatics towards comprehensive Electronic Health Records (EHRs) has enabled a wide range of secondary use cases for this data. However, due to a number of well-justified concerns and barriers, especially with regards to information privacy, access to real medical records by researchers is often not possible, and indeed not always required. An appealing alternative to the use of real patient data is the employment of a generator for realistic, yet synthetic, EHRs. However, we have identified a number of shortcomings in prior works, especially with regards to the adaptability of the projects to the requirements of the German healthcare system. Based on three case studies, we define a non-exhaustive list of requirements for an ideal generator project that can be used in a wide range of localities and settings, to address and enable future work in this regard.

Numerical Model of Current Speed in Bojong Salawe Beach, Pangandaran West Java Province

The purpose of this study was to determine the hydrodynamic conditions at Bojong Salawe beach. The method used in this research is a quantitative method, where numerical data is collected to support the formation of numerical models such as wind, bathymetry, and tide data. The hydrodynamic model will be made using Mike 21 with the Flow Model FM module to determine the current movement pattern based on the data used. In the west monsoon with a maximum instantaneous speed of 0.04 - 0.08 m/s, while in the east monsoon it moves with a maximum instantaneous speed of 0,4 – 0,44 m/s. The dominant direction of current movement tends to the northeast. The results indicate the current speed during the east monsoon is higher than the west monsoon. The difference in the current speed is also influenced by the tide conditions; higher during high tide and lower during low tide. Monsoons also have a role in the current movements, though the effect is not very significant.

Open Transparent Communication about Animals in Laboratories: Dialog for Multiple Voices and Multiple Audiences

In this article, I offer insights and proposals to the current movement for increased openness and transparency about animal use in laboratories. Increased transparency cannot be total transparency—as no story or picture can ever be complete. When research advocates share their stories, they must decide which words and pictures to edit out. I ask here: Who of the listening “public” gets a chance to revisit this editing, and find the information that is important to them? To the extent that (what I call) the “new openness” attempts to speak to a “lay public” and exclude animal activists, I suggest that refinement-focused animal protectionists deserve enhanced avenues of openness and inclusion—which some research advocates might fear giving to more extreme activists and which a less invested “lay public” may not want or need. I conclude with some specific examples and suggestions to not just invite inquiry from animal advocates, but to bring them in as witnesses and participants, to learn from and incorporate their concerns, priorities, expertise, and suggestions. This can bring a diversity of ideas and values that could improve the quality of science, the credibility of animal researchers, and the welfare of the animals in laboratories.

Study of the biogas potential generated from residue: peanut shells

The increase in agricultural production generates a large volume of waste, which may lead to concerns about its proper destination. The main economic activity in Herculândia City, Western region of São Paulo State, Brazil, is the production and processing of peanuts. In this process, a large volume of peanut shells is generated. Following the current movement of using waste for energy purposes, in compliance with what was established by the Sustainable Development Goals (SDGs), this work aimed to carry out a study on the biogas potential generated from peanut shells. To this end, a low-cost biodigester prototype was built, which, over a period of 108 days, produced biogas and biofertilizer. The results showed that there was production of biogas from peanut waste; however, the volume produced did not provide savings in electricity costs when compared to the production of biogas from animal waste. Nevertheless, the work demonstrated the importance of providing solutions to the disposal of peanut shells, effectively mitigating future environmental problems, and serving as an alternative for generating sustainable and low-cost energy, especially for small producers.

Current Movement Follows Previous Nontarget Movement With Somatosensory Stimulation

This study examined whether the current movement follows the previous movement and whether this process is enhanced by somatosensory stimulation or is gated while retrieving and using the memory of the previously practiced target end point. Healthy humans abducted the index finger to a previously practiced target (target movement) or abducted it freely without aiming at the target (nontarget movement). The end point of the nontarget movement had a positive correlation with the previous nontarget movement only when somatosensory stimulation was given during the previous movement, indicating that the current nontarget movement follows the previous nontarget movement with somatosensory stimulation. No conclusive evidence of whether this process is gated by retrieving and using the memory of the previously practiced target was found.

Collective Visioning: Igniting the Radical Imagination

As the spaces which once existed within the university for the co-imagining of liberatory political praxes diminish, social movements are increasingly reverting to methods of collective visioning which have been developed on the streets to theorise radical social change. I argue that such methodologies provide important opportunities for a reappraisal of our hierarchical student/teacher relations, and make the case that we can collectively learn much more from within our movements than anyone might hope to teach us from outside. The article traces our current movement wave, and locates contemporary forms of collective visioning within a wider lineage of knowledge co-production in social movements. The neoliberal subversion of university education is examined, and proposals made for ways in which we might challenge these hegemonic conditions. I conclude that the liberatory epistemologies and forms of knowledge co-production explored in this article offer significant potential for developing new modes of praxis for our current wave of ecological and anti-capitalist activists both inside and outside the university.
