Abstract:

The integrated reflective semiconductor optical amplifier (RSOA) and electro-absorption modulator (EAM) is viewed as an appealing solution to the colorless transmitter on the optical network unit (ONU) side of wavelength-division multiplexed (WDM) passive optical networks (PONs), for its broad modulation bandwidth and high optical gain. However, the conventional RSOA–EAM usually exhibits a poor upstream signal eye-diagram because it can hardly simultaneously saturate the downstream signal and boost the upstream signal as required. By exploiting the polarization-depended RSOA gain, we propose a

Abstract:

With abundant natural resources, East Kalimantan has a major environmental issue: forest fires. Several cases in East Kalimantan currently garner pros and cons regarding relocating Indonesia's new capital to the region. Fires in peatlands are usually dominated by smoldering processes, resulting in the highest emissions of carbon monoxide (CO) particles. Carbon monoxide gas is odorless, colorless, and tasteless, making it difficult to detect, yet highly toxic, and can cause illness in humans. Considering the dangers caused by CO gas, this research aims to create a CO gas detector to determine a

Abstract:

Abstract A new organic mineral species, stanevansite, ideally Mg(C2H3O3)2·2H2O, was discovered from the western end of Pusch Ridge in the Santa Catalina Mountains (32° 21′ 42″ N, 110° 57′ 30″ W, at the elevation of 975 m), north of Tucson, Arizona, USA. It occurs as sprays of bladed crystals (up to 0.40 × 0.07 × 0.03 mm). Associated minerals include lazaraskeite, chrysocolla, malachite, wulfenite, mimetite, phosphohedyphane, cerussite, hematite, calcite, microcline, phlogopite, and quartz. Stanevansite crystals are colorless in transmitted light, transparent with white streak and vitreous lust

Abstract:

Cucumis melo L. is an important fruit with widespread consumption and commercial value. However, an undescribed disease affecting Hami melon (Cucumis melo L. var. Luhoutian) plants has consistently emerged in the Qihe region of Dezhou, Shandong Province of China since 2021. The disease can occur in both seedling and mature stages of Hami melon plants, and in severely diseased areas, the incidence rate was seen as 40 to 80%. During the seedling stage, the initial symptom is the appearance of water-soaked spots on the leaves. As the disease progresses, the leaves develop necrotic spots, and seve

Abstract:

The use of mouthwashes has shown that they can reduce the viral load of Covid-19, with the most promising mouthwashes containing hydrogen peroxide (H2O2). Cetylpyridinium Chloride (CPC), Povidone Iodine (PVP-I) and Chlorhexidine Gluconate (CHX) [1]. Since Sars-Cov-2 is transmitted by airborne droplets and the respiratory tract is the main route of infection, having a way to clear this pathway can ensure that the practitioner does not contract Covid-19 in their patients. Discussion Chlorhexidine (CHX) CHX is a wider-spectrum antiseptic that has an action on Gramnegative and Gram-positive facult
