AbstractFebrile seizures (FS) in children are common, but little is known about parents’ perceptions and knowledge of FS. We interviewed parents of children aged 6 months to 6 years affected by FS (FS group, 65 parents) or unaffected (control group, 54 parents). In the FS group, 32% said they knew their child had an FS when the first event occurred, and 89% described fear when the child had a seizure, with a median intensity of 10/10 (Q25/Q75: 9/10). Related to follow-up, 77% in the FS group (will) observe their child more carefully after the first seizure happened, and 63% (will) give antipyretics earlier at a median temperature of 38.2 °C (100.8 °F). In the FS group, 62% were unaware of FS before the first event (54% of control group did not know about FS thus far, n.s.). In the FS group, 20% would put a solid object in the mouth of a child having a seizure (control group, 39%, p = 0.030), and 92% would administer an available anti-seizure rescue medication (control group, 78%, p = 0.019). In the FS group, 71% feared that children with FS might suffocate (control group, 70%, n.s.).Conclusion: Information about FS and their management should be more available to improve parents’ coping and patient safety. What is Known:• Febrile seizures in children are common.• The prognosis of children suffering from febrile seizures is usually rather good. What is New:• Over half of parents had not informed themselves about febrile seizures so far; and only 32% of parents realized their child had a febrile seizure when it occurred.• Most parents described own fear with a median intensity of 10/10; and 63% (will) give antipyretics earlier at a median temperature of 38.2 °C (100.8 °F).

Abstract Most asteroids with a diameter larger than ∼ 300 m are rubble piles i.e. consisting of more than one solid object. All asteroids are rotating but almost all asteroids larger than ∼ 300 m rotate with a period longer than 2.3 hours, which is the critical period where the centrifugal force equals the gravitational force. This indicates that there are nearly no adhesive interaction forces between the asteroid fragments. We show that this is due to the surface roughness of the asteroid particles which reduces the van der Waals interaction between the particles by a factor of 100 for micrometer sized particles and even more for larger particles. We show that surface roughness results in an interaction force which is independent of the size of the particles, in contrast to the linear size dependency expected for particles with smooth surfaces. Thus, two stone fragments of size 100 nm attract each other with the same non-gravitational force as two fragments of size 10 m.

AbstractVat photopolymerisation describes resin-based additive manufacturing processes in which ultraviolet light is used to layer-wise solidify liquid resin into a desired 3D shape. If the starting resin is a dual-curing formulation the object is also thermally cured to attain its final properties, obtaining either an elastomer or a thermoset. Here, we introduce cavity vat photopolymerisation, in which one photopolymer resin produces a composite material of an elastomer and thermoset. Cavities of any geometry are purposefully designed in the solid object and then filled with liquid resin during printing due to negative pressure. Thermal curing then solidifies the resin in the cavities into an elastomer, forming a distinct interface held together by strong covalent bonds. Hybrid specimens indicate improved damping, reduced fragmentation upon fracture and increased local elasticity, and we suggest several hard-shell/soft-core applications that might benefit.

Abstract Febrile seizures (FS) in children are common. Little is known on parents’ perceptions and knowledge of FS. We interviewed parents of children aged 6 months to 6 years affected (FS-group, 65 parents) or unaffected by FS (unaffected group, 54 parents). Of the FS-group, 32% said they knew their child had a FS when the first event occurred. Of the FS-group, 89% described fear when the child had a seizure with a median intensity of 10/10 (Q25/Q75: 9/10). Of the FS-group, 77% said they (will) observe their child more carefully since the first seizure had happened, 63% (will) give antipyretics earlier at a median temperature of 38.2°C (100.8°F). Of the FS-group, 62% had not informed themselves about FS before the first event occurred (unaffected group: 54% had not informed themselves about FS so far). Of the FS-group, 20% would put a solid object in the mouth of a child having a seizure (unaffected group 39%), and 92% would administer an available anti-seizure rescue medication (unaffected group 78%). Of the FS-group, 71% stated children with FS might suffocate (unaffected group 70%). Conclusion: Information about FS and its management should be more widespread to improve parents’ coping and patient safety.

Production is the provision of goods and services with due regard to the value of justice and benefit to society. Production also has an important role in determining the standard of human life and the prosperity of a nation. In this study, the focus is on salt production in Madura. Salt is a white solid object in the form of crystals which is a collection of compounds with the largest portion of sodium chloride (NaCl) and other compounds such as Magnesium Chloride, Magnesium Sulfate, Calcium Chloride, etc. Broadly speaking, Islamic economics is a science that studies human behavior in an effort to meet needs with limited means of fulfilling needs within the framework of Islamic Sharia. The approach used is a qualitative approach with the type of case study research, namely research on humans (can be a group, and individuals), events, settings in depth. As well as data collection techniques are observation, interviews and documentation. This case study is very relevant and is in line with the use of a modern tool in the use of salt production in Madura, the first to increase production and improve the quality of Madurese and national salt. The emphasis is on quality, quantity, maximization and participation in the production process which provides different functions in the production process

This paper briefly reviews some of the excavated evidence for decorated boxes found at sites from Mesopotamia to Central Asia in the late 3rd millennium BC, and concludes that one published from an Akkadian grave at Nippur is a Harappan import. Similar types of box found at Gonur depe were used to contain mirrors, and this also provides a new explanation for the Nippur box. Remains of other types of decorated box are also known from elite graves at Gonur and Ur, some of a size consistent with trunks or chests, but others much smaller and employing iconogra- phy peculiar to their cultural context. This paper draws attention to the fact that the boards for the “Game of Twenty Squares” were originally hollow in order to hold the pieces, and that the so-called “Standard of Ur” was also a box, rather than the solid object it has been reconstructed and known as. In other regions, such as southeast Arabia and Iran, small compartmented boxes were also carved from chlorite but larger examples were probably also made of wood. The fired clay boxes also known from eastern Iran and southwest Central Asia may well have had wooden counterparts which have not survived. In short, a much greater variety of boxes of different types and sizes were used at this period than is generally acknowledged.

Additive manufacturing (AM) is a method in which three-dimensional structures are successively laid down to create a solid object. The inherent advantages of AM technology are successfully drafted and exploited by the different organization across the globe. During the time of pandemic i.e. COVID-19, 3D printing has come to rescue and has been used for manufacturing critical medical supplies. 3D printing has been used in manufacturing some of the critical items like ventilators valves, face shields, swabs, oxygen valves, hand sanitizer holders, 3-DP lung models, etc. The main reason for its success has been the ability of 3D printing to print locally by using digital designs and thus reducing the number of supply chain actors. Also, the ability of 3D printing to manufacture/print complex geometrical designs locally is the main reason for its successful adoption during COVID-19. In this paper, we have discussed how AM has come to the forefront in fighting this pandemic. Various AM techniques have played a critical role in bridging the supply chain gap in the medical industry and locally printing critical devices. There were certain apprehensions before the pandemic along with slow adoption but this pandemic has also increased the adoption of AM due to its ability to overcome the demand created by COVID-19.

Along with the increase in population is directly proportional to the need for energy sources both to support people's lives and the increase in the industrial sector in Indonesia. One of the most widely used sources of electricity is wind. Wind turbines are very sensitive to the wind speed they receive, as a result of fluctuations in wind speed that affect wind rotation speed. For this reason, the author has the idea to combine a wind turbine with a solid object turbine, it is hoped that the combination can produce more consistent rotation. The tool used is a wind turbine combined with solid blade ball weights 8, 9 and 10 and ballast of 10 gr, 20 gr and 30 gr for each blade and wind speeds of 3.3 m / s, 3.6 m / s and 3.9. m / s with the experimental research method, the experiment was carried out 3 times in each tool for ± 2 minutes which was expected to produce a combination of the variables studied in the form of a turbine with the maximum rotational speed and the most consistent rotation. From these experiments, it was found that a turbine with 10 blades, a weight of 10 gr at a wind speed of 3.9 m / s had the fastest rotation, namely 116.43 rpm while a 9 blade turbine with a weight of 30 gr at all three wind speeds was the turbine with the most consistent rotation, namely the difference between the top and bottom rotation is 2.53 rpm.

The author describes the following rare case of finding a metallic foreign body in the uterus. On May 18, 1890, he was approached by a woman who, on May 6, being on the 3rd month of pregnancy, in order to have a squatting abortion, inserted a hairpin into her uterus. I had a miscarriage. When examined, the vagina is free and the uterine opening is closed. The uterus is slightly enlarged, it is still in retroversio. In the anterior vault, on the right, the blunt end of a barely moving object is felt. With a probe, at the place of the internal uterine os, you come across a solid object, between the dark as the uterine cavity above is empty.
