Theoretical Aspects of Estimate of Safe Limit of Monetary Expansion

The development of a sensitive alpha-NaYF4:Yb3+, Er3+ solid-phase upconverting platform (UCP) has been realized using Moringa oleifera leaf extract for selective detection of arsenic (As III) contamination in drinking water. The presence of polyphenols in the leaves extract is shown to induce luminescence resonance transfer (LRET), diminishing thereby the Er3+ upconverting red and green emissions activated by 980 nm excitation. However, addition of As3+ species interrupts the LRET process and restores emission proportionately. This feature allows platform to selectively detect arsenic pollution in water below the safe limit of 10 ppt. The uniqueness of UCP lies in monitoring the As3+ contamination in samples containing heavy ions (Cd2+, Hg2+) as well, without apparent effect on the signal reproducibility. UCP is also found to be insensitive to other interfering ions like Pb2+, H2PO4-, F-, Cl-, Ca2+, Mg2+, Sn2+, Cr6+, Fe2+ and Co2+, if present.<br><br>

AbstractThe present study aims to analyze the temporal variations of PM10 and to assess the health risk indexes caused by trace elements from particulate matter (PM10) via inhalation, ingestion, and dermal absorption by adults and children in Copșa Mică (Romania) during 2009–2019. The results revealed a high multi-annual mean concentration of PM10 and trace elements. The analyzed air pollutants showed a decreasing trend during the studied years, therefore 44.11%, 43.48%, 36.07%, 16.02%, and 15.80% lower values were observed for As, Cd, Ni, PM10, and Pb, respectively, due to environmental regulations. The daily exceedance percentage of Pb and Cd was very high, representing 21.74% and 11.26%, followed by PM10 and As concentrations with 4.72% and 3.92%. The ratio between the trace element concentration measured in Copșa Mică and the country average was 2.46, 4.01, 2.44 and 10.52 times higher for As, Cd, Ni and Pb. The calculated Hazard Quotient values via inhalation were higher than the safe limit (1), which accounted 1.81, 3.89 and 4.52, for As, Cd and Ni, respectively, indicating that the trace elements might present a non-carcinogenic risk to both adults and children. Furthermore, the concentration of all studied trace elements in Copșa Mică showed cancer risk for adults via inhalation and dermal absorption as well.

Backpacks are often used by school children as a container or a place to carry their school materials and equipment, so these types of backpacks are very popular with school children. The large number of students wearing backpacks to school can be proven from the results of a survey conducted at SD N Bumisari, Natar District, South Lampung. Of the total number of subjects, 456 elementary school students carried 404 students (88.6%), and 52 students (11.4%) carried sling bags. But they rarely pay attention to the weight of the burden on the bag he carries everyday which turns out to cause injury to back pain.The tool is made in the form of a wearable device where the tool is in the form of a backpack that can be carried anywhere without having to require AC current as input voltage to the tool, because the power uses DC current with a voltage of 5V, the device is made using a microcontroller supported by a 10 kg loadcell sensor, modules HX711, keypad, plus an indicator component in the form of a buzzer. If the bag load exceeds the safe limit, the buzzer indicator will sound.

Standard Set

Transmission line is a very absolute thing in an electric power system. In the distribution of electricity from generating centers to loads (consummers), where the distance is quite far it is done through the transmission line. Transmission channels those are generally used based on construction are the lattice type and steel pole. The transmission channel has a safe limit against other objects around it according to the standard set. The air transmission line uses a TACSR (Thermal Aluminium Conductor Steel Reinforce) conductor which has a working capacity with temperatures up to 1500C. Based on calculations when the distance is 212m with a temperature of 1500C the value of the roof is 9,40m. When the distance is 173m with a temperature of 1500C the maximum value of the roof is 7.8m. When The condition of the temperature and the length of the span affect the value of the roof the greater of the temperature and the length of the span, so the greater of the resistance.ABSTRAK:Saluran transmisi adalah suatu hal yang sangat mutlak dalam suatu sistem tenaga listrik. Dalam penyaluran tenaga listrik dari pusat-pusat pembangkit ke beban (konsumen), dimana jaraknya cukup jauh maka dilakukan lewat saluran transmisi. Saluran transmisi yang umum digunakan berdasarkan konstruksinya adalah tipe lattice dan steel pole. Saluran transmisi ini memiliki batas aman terhadap obyek lain yang ada di sekitarnya sesuai standar yang ditetapkan. Saluran transmisi udara menggunakan konduktor jenis TACSR (Thermal Aluminium Conductor Steel Reinforced) yang memiliki kemampuan kerja dengan suhu sampai 1500C. Berdasarkan perhitungan pada saat jarak span 212 m dan dengan suhu 1500C andongan maksimumnya bernilai 9,40 m. Pada saat jarak 173 m dan dengan suhu 1500C andongan maksimalnya 7,8m. Pada saat jarak 233 m dengan suhu 1500C andongan maksimumnya adalah 10,58m. Keadaan suhu dan panjang span mempengaruhi nilai andongan, semakin besar suhu dan panjang span maka nilai andongan akan semakin besar.

Forbidden Gap

There exists an implicit potential limitation in every physical discoveries that has been implemented and understood. However, the limitations can be bounded within a safe limit to prevent any constructing theory to be free from errors. As, it’s the inert nature of the humans, to go far beyond the scope of experimental findings in order to pursue any studies with the sole help of logical reasoning and mathematics, the argument can be prevailed in the form of WEAK Clampdown Effect & STRONG Clampdown Effect. More, the theories are constructed out of physical nature, more the theory gets hypothetical without any finding evidence, but that does or doesn’t actually justify the phenomenon, that too with the more increment of KARDASHEV Scale, more moderate ways of experimentation got developed curbing down the limitations within the human limit of ‘ERRORS’, that does can be neglected by approximation. Relationship being cross-judgmental on the basis of the computational limits and calculation accuracy, leading to a soft singularity, as a warning, that if computer powers cannot be checked on the basis of error approximations, then this may lead to the hitting of a hard singularity, that in phase with the forbidden gap (or after the optimum limit that arises at the core constraints of nature) to prevent the computation being carried off with respect to super-intelligence machines that are cognitive capability oriented future computers responsible for self growth & reproduction with more improvement algorithm, restricting all forms of humanity & constraints the human growth by virtue of limiting capacities of the humans as compared to computers.
