The article reveals and systematizes the main types of conflicts over drinking water, which broke out in the world during the late XX and early XXI centuries. For each type of conflict, a specific example is given and briefly disclosed its history, the main reasons for its deployment are analyzed. It is noted that the overwhelming majority of past and present conflicts are local and take place within national states. But with population growth, industrialization and urbanization, the demand for water is only growing, which leads to increased competition for it and can provoke new disputes over this resource. Separately, the conflict over access to hydro-resources on the Russian-occupied Crimean Peninsula is highlighted. The experience of studying conflicts over water demonstrates that even local disputes over hydro resources often result in human casualties, worsen people's living conditions, and carry health risks, in particular famine and epidemics.

In the process of harvesting sugarcane at a sugar factory, the Sugarcane Harvester is a tractor used to harvest sugarcane equipped with a slicer knife. Nowadays slicers are still imported from abroad, and the availability is scarce and the price is still expensive. One of the efforts to find an alternative to the slicer is to use leaf springs by hardening the metal through a heat-treatment process. Namely the process of heating steel to temperatures above the critical area followed by rapid cooling called quenching. The purpose of this study was to determine the effect of holding time and the effect of cooling media on the hardness and impact strength of leaf springs and to determine the ideal holding time and the most optimal cooling media to increase the hardness and impact strength of leaf springs. As for the research method, the spring leaves were heat-treated with a temperature of 8500 C for 30 minutes and 60 minutes and then cooled using oil, saltwater, and water as media. The method used is observation, literature study, testing, and documentation.
The results obtained from this study were at a temperature of 8500 C with a holding time of 30 minutes the best hardness value was 477 VHN and 0.42% increase, the best impact strength value was 0.03433 J / mm2 and 87.71% decrease, and the two cooling media, namely oil. At a temperature of 8500C with a holding time of 60 minutes the best hardness value was 534 VHN and 12.42% increase, the best value of impact strength was 0.03203 J / mm2 and 88.53% decrease, and the two cooling media were oil as well. So that oil is the most optimal medium for changing the mechanical properties of the Sugarcane Harvester slicer because the oil can carry a carbon layer from the cooling process that takes place and the cooling rate of the oil is not too fast from the cooling media of brine and water because of its viscosity.

Coal is still widely used as the main fuel in the industry, especially the power generation industry (PLTU), cement plants and etc. Coal is a fossil fuel whose availability is thinning and its fires produce CO2 emissions that cause a rise in greenhouse gas (GHG) concentricity. On the other biomass is an alternative energy source that is abundant, including empty bunches of oil palm (TKKS), but has poor combustion properties compared to coal when burned directly. The properties of biomass burning can be improved by certain treatment, one of which is through the process of torrefaction. Biomass torrefaction has a calorific value equivalent to sub-bituminous coal B, so it has the potential to be used as an alternative fuel for coal. The purpose of this study was to determine the maximum temperature that occurs in the burner. In this study co-combustion was conducted on simulation of ANSYS program with powder system (pulverized combustion) because this type in recent decades is widely used in industry. In this study conducted a simulation on ANSYS to determine the temperature on the burner and the concentration of emissions produced. The results showed that the simulation of co-combustion burner burner showed the maximum temperature reached 970°C. The effect of burner and burner temperature in the form of swirl provides sufficient oxygen with more perfect combustion resulting in decreased concentration of CO2 emissions and low concentration of N2 due to higher nozzle temperature. High temperatures lower the concentration of SO2 in the burn chamber.Keyword: Co-combustion, pulverized co-combustion simulation, TKKS torrefaction, burner.

Published: August 2021

During the pandemic, face-to-face training should not be carried out to reduce the spread of the covid outbreak. Therefore, online teacher professional development is an alternative method to replace the face-to-face training. In a program implementation, evaluation is an important component to determine whether the program has been implemented well or not. This evaluation is important to determine the effect of this online training on improving STEM PCK teachers. The evaluation used the CIPP model (Context, Input, Process, and Product), with the embedded mixed method research. This research was conducted on 60 science teachers of SMP alumni online training organized by PPPPTK IPA, from the “Sayangi Bumi” classroom. The results of the context evaluation show that 100% of respondents stated that the program is in accordance with the needs of teachers to strengthen their PCK., while the resources used in the program (Input evaluation) were good. The program implementation process ran 100% as planned and the product evaluation shows an increased teachers' understanding of the STEM approach. Teacher considered that the online professional development is very useful for teachers and can develop their skills in implementing STEM learning during distance learning. Online PD, apart from low-cost, can actually be an alternative way in improving teachers' STEM PCK competence and it also can reach all islands in Indonesia

Endoscopic treatment of complex multiloculated hydrocephalus in children, steps that may help to decrease revision rate
Authors: Elkheshin Sherif Elsayed , Bebars Mohamed 
Published: August 2021

Background:Multiloculated hydrocephalus (MLH) is associated with increased intracranial pressure, with intraventricular septations, loculations, and isolation of parts of the ventricular system. Search continues for ideal surgical remedy capable of addressing the dimensions of the problem. We aimed to evaluate endoscopic septal fenestration and pellucidotomy combined with proximal shunt tube refashioning and further advancement into isolated loculations of the ventricular system containing choroid plexus.Methods:This retrospective study was conducted on 55 patients with symptomatic complex MLH who underwent endoscopic surgery. The collected data included patients’ age, gender, presenting manifestations, operative details, rate of remission of preoperative clinical and imaging signs, postoperative complications, redo surgery, or extra shunt hardware insertion. Patients were divided into Group A (underwent the standard technique of endoscopic multiseptal wide fenestration and final ventriculoperitoneal shunt insertion) and Group B (modified technique by adding extra side ports along the proximal shunt hardware).Results:Groups A and B included 25 and 30 patients, respectively. The percentage of patients showing improvement of almost all manifestations was higher in Group B compared to Group A, with no significant difference (P> 0.05). Group B had lower rate of complications (20% vs. 36%,P= 0.231), insertion of two shunts (16.7% vs. 20%,P= 1.000), and redo surgery (20% vs. 44%,P= 0.097).Conclusion:The modified technique was associated with better outcomes in terms of the use of single shunt and redo surgery. Launching randomized clinical trials to compare the two techniques are recommended to ascertain the efficacy of the modified technique.
