Rancang Bangun Alat Pendeteksi NOx dan CO Berbasis Mikrokontroler ESP32 dengan Notifikasi Via Telegram dan Suara

The design of NOx and CO detectors based on notifications via telegram and voice has been carried out. This detector consists of a gas sensor MQ-135 as a nitrogen oxide detector and an MQ-7 sensor as a carbon monoxide detector. Data processing is carried out using an ESP32 microcontroller which can send results to a telegram bot and play sound using speakers connected to the ISD 1820 sound module. The tool made can send notifications if the concentration of nitrogen oxides and carbon monoxide exceeds 50 ppm. The test is carried out by burning waste to produce smoke. Burning smoke contains various gases and particles that are harmful to the body. The characterization of the MQ-135 sensor was carried out by comparing the data obtained from the ISPU to measure nitrogen oxide gas and producing an error value of 9.09%. Meanwhile, the characterization of the MQ-7 sensor was carried out using a biogas analyzer and resulted in an error ratio of 3.26%. These results prove that the tools that have been designed can work well.

The lecture presents the main mechanisms of damage to the body, the typical clinical picture and the principles of emergency medical care (EMС) and intensive care in victims of acute poisonings by toxic gases. Due to the fact that the risk of simultaneous appearance of a large number of victims with such poisonings is always high in the conditions of chemical production, the issue of providing EMС to this group of patients is always relevant. The lecture considers the features of damage to the human body with ammonia, chlorine, hydrogen sulfide, arsine, nitrogen oxides, formaldehyde, carbon monoxide and gasoline vapors. All these chemical compounds are widespread chemical reagents and reaction intermediates in production. The inhalation route by which volatile substances enter the body determines the accelerated development of clinical symptoms due to the rapid pass of toxic chemicals into the blood of patients. Disorders in the functioning of the external respiratory system are among the most common ones when inhaling such aggressive chemical compounds as ammonia, chlorine, nitrogen oxides, formaldehyde, gasoline vapors. The intake of carbon monoxide, nitrogen oxides and hydrogen sulfide poses a high risk of hemic hypoxia and related damage to the central nervous system and cardiovascular system. Inhalation of compounds such as hydrogen sulfide, arsine, formaldehyde, carbon monoxide determines the development of disorders of tissue respiration. Almost all chemical compounds, the action of which is presented in the lecture, can have a general toxic effect on patients. The need to immediately stop the contact with the toxic substance, prevention and intensive care of patients with acute respiratory failure syndrome, use of antidotes and drugs with antihypoxic effect, which improve tissue respiration and promote energy production, are highlighted when considering the aspects of providing EMС.

Ceramic Foams

Hazardous byproducts emissions such as nitrogen oxides (NOx) and carbon monoxide (CO) might be controlled by the use of radiant porous burners. Those heaters require a solid porous matrix where combustion reaction takes place, reason why the heat transfer is much more efficient. This project was based on a rheology study of an alumina slurry, where parameters like viscosity and tixotropy were the guide to select the appropriate formulation to be used in the fabrication of ceramic foams by the replica method. Low strength samples were produced after the first thermal treatment, explained by the absence of a plasticizer when using PVA as a binder. Incomplete sintered foams were obtained due to an insufficient soak time.

SummaryFactor VIII occurs in the body in two different forms. In lymph factor VIII is bound to chylomicra. In plasma, factor VIII is bound to a protein.After delipidation of chylomicra we obtained a glycoprotein with a high polysaccharide content and a molecular weight of approx. 160,000.In plasma, factor VIII is attached to a protein which is present in normal concentrations in plasma of patients with haemophilia A and in serum (co-factor VIII).This factor is deficient in both the plasma and the serum of patients with von Willebrand’s disease.The binding between factor VIII and co-factor VIII is reversible.Some properties of these two factors are described.

Birth Of Tragedy

This essay seeks to dispel entrenched critical opinion regarding dance across Nietzsche's writings as representative of Dionysian intoxication alone. Taking as its prompt the riposte of Alain Badiou, ‘Nietzsche is miles away from any doctrine of dance as a primitive ecstasy’ and ‘dance is in no way the liberated bodily impulse, the wild energy of the body’, the essay uncovers the ties between dance and Apollo in the Nietzschean theory of art while qualifying dance's relation to Dionysus. Primarily through an analysis of The Dionysiac World View and The Birth of Tragedy, the essay seeks to illuminate enigmatic statements about dance in Nietzsche (‘in dance the greatest strength is only potential, although it is betrayed by the suppleness of movement’ and ‘dance is the preservation of orderly measure’). It does this through an elucidation of the specific function of dance in Nietzsche's interpretation of classical Greece; via an assessment of the difficulties associated with the Nietzschean understanding of the bacchanal; and lastly through an analysis of Nietzsche's characterization of dance as a symbol. The essay culminates in a discussion of dance's ties to Nietzschean life affirmation; here the themes of physico-phenomenal existence, joy and illusion in Nietzsche are surveyed.

AbstractOnce the body dies, the indigenous microbes of the host begin to break down the body from the inside and play a key role thereafter. This study aimed to investigate the probable shift in the composition of the rectal microbiota at different time intervals up to 15 days after death and to explore bacterial taxa important for estimating the time since death. At the phylum level, Proteobacteria and Firmicutes showed major shifts when checked at 11 different intervals and emerged at most of the postmortem intervals. At the species level, Enterococcus faecalis and Proteus mirabilis showed a downward and upward trend, respectively, after day 5 postmortem. The phylum-, family-, genus-, and species-taxon richness decreased initially and then increased considerably. The turning point occurred on day 9, when the genus, rather than the phylum, family, or species, provided the most information for estimating the time since death. We constructed a prediction model using genus-level data from high-throughput sequencing, and seven bacterial taxa, namely, Enterococcus, Proteus, Lactobacillus, unidentified Clostridiales, Vagococcus, unidentified Corynebacteriaceae, and unidentified Enterobacteriaceae, were included in this model. The abovementioned bacteria showed potential for estimating the shortest time since death.
