Biochemical Treatment and Utilization of Fecal Wastewater

Haiyan Hu, Xin Zhou
In order to treat and utilize urban fecal wastewater more effectively, a process for biochemical treatment of fecal wastewater from urban settlements was established in this study. After treating the fecal wastewater collected, solid and liquid organic fertilizers can be obtained. Compared to the commercially available urea, the solid organic fertilizer can increase the yield of okra by 12.89% at podding stage, while the liquid organic fertilizer can prolong the flowering period of Chinese orchi...

Impact of COVID-19 Pandemic Outbreak: CO2 and SO2 Emission Reduction over China

Abel Nsabimana, Edward Hingha Foday Jr
The COVID-19 pandemic has disorganized humans economically, physically, socially and psychologically. More than 353,334 people died in China and about 5,593,631 cases are confirmed so far (with thousands of new cases per day) all over the world and others are still quarantined or confined. Beyond such odd impact with the geometrical death rate, this paper gives a different consideration of the pandemic effects, such as the environment preservation during the height of the pandemic which is a pos...

A Brief Review in Effect Factors on Peatland Ecosystem

Ihab Alfadhel
Peatland ecosystem plays an important role in the global climate change because they act as a pool or sink of the gasses. There are several factors which influence the environmental consequences of peatland especially in relation to climate change. The main influences are: 1) carbon dioxide, 2) methane flux, 3) nitrous oxide (N2O) and 4) others environmental factors. These atmospheric gases concentrates constitute roughly 73 percent of the overall positive energy flux variation. Carbon dioxide i...

Effect of Water and Fertilizer Regulation on the Soil Available P Content in Winter Wheat at West Lake Plain and Baiyang Lake in China

Jinbo Zhao, Ming Chen, Jiawei Li, Jinghua Zhou
Water and nutrients are the basic requirements for crop growth, which are mutually interacting and restricted. This paper studied winter wheat (wheat breed: Ji wheat 22) on changes in soil nutrient leaching in the regulation measures of water and fertilizer (two irrigation methods: traditional irrigation (A) and water-saving irrigation (B); three fertilization factors: no fertilization (CK), traditional fertilization (FC) and optimized fertilization (FO)). The results showed that under the diffe...

Pollution Status of Heavy Metals in Surface Sediments Collected from West Coast of Peninsular Malaysia

Tijjani Rufa’i Buhari, Ahmad Ismai
The present study examined status of heavy metals (Cu, Zn, Pb, Cd and Ni) pollution in the surface sediments of west coast of Peninsular Malaysia. Heavy metals concentrations were determined by using air acetylene flame atomic absorption spectrophotometer (AAS) Perkin Elmer Analyst 800. The results of particle size analysis of the surface sediments indicate high metals concentrations at sampling sites with high content of sand and clay particles. The results of Pearson’s correlation analysis bas...

Indian Monsoons Roaming in Time and Space and Global Climate Calamities Control Vitalities

Malik Muhammad Nazeer
The huge rise in worldwide almost all calamities is the aftermath of extreme Global Heat and Temperature (GHT). These have taken a steep upward turn with continuously flourishing growth since 1965/70, steered by implementation of Indus Basin Water Treaty of 1960 (IBWT). This 16.48 ZJ (Zeta Joules = 1021 Joules) rate of rising Global Heat could have been reduced by about 9.235 ZJ through optimal development and use of Pakistani resources in its local water evaporation and precipitation cycle (WEP...

Influence of Paper Mulberry Presence on Native Tree Species in Mabira Central Forest Reserve in Uganda

Alongo Boniface Byamalong Yamungu
Mabira Central Forest Reserve in Uganda (MCFR) is facing biodiversity loss, especially other tree species in the paper mulberry dominated area due to Charcoal burning activities and the presence of paper mulberry (Broussonetia papyrifera). Paper mulberry (Broussonetia papyrifera) in the family Moraceae or Morus papyrifera is found mostly in the production zone identified as hotspot of biodiversity in Mabira central Forest reserve. Several studies in western and East Africa have indicated that pa...

Solar, Lunar and Venus Roles in Some Global Climatic Events

Malik Muhammad Nazeer
Any substantial and extraordinary role of a Solar, Lunar or Venus in the huge rise in present Global Heat Contents (GHC), Temperature, Hurricanes, storms, wildfires and resulting worldwide huge growth in calamities after 1965/70 was denied on the ground that no sizeable change in activities of these bodies matching in timings, stature and persistency with the Global Heat and Temperature (GHT), etc. was observed or reported. Yet their activities are contributing and these may be mishandled by any...

Time Variations Analysis of the Geomagnetic Field in the Municipality of Macaé, Brazil

Laisa Prata Moreira Fernandes, Joao Victor Jobim de Souza e Silva, Iago Reis Homsi, Paula de Carvalho Garcia, Gabriel Teixeira de Oliveira Barroso, Tainá Rebelo e Ribeiro, Gabriel Gomes Dias de Oliveira, Vania Regina de Oliveira Branco, Hans Schmidt Santos
This paper presents the analysis of temporal variations of the geomagnetic field in the municipality of Macaé, Brazil. Current and historical magnetic field from the IGRF (International Geomagnetic Reference Field) and Gufm1 models were used to construct two-dimensional maps from 1590 to 2019. Analysis of the maps revealed that there was a large decrease in total magnetic field magnitude from around 48,000 nT in 1590 to 23,000 nT in 2019, i.e., a decrease of more than 50%. This decrease was inte...

New Insights in Prime Roles of Indian Subcontinent in Nurture of Global Heating and Hurricanes with Review of the Only Window for Their Calamities Control

Malik Muhammad Nazeer
A new paradigm of Indian Subcontinent prime roles in governing Global Heat contents and Temperature (GHT) and North Atlantic Hurricanes (NAH) etc. is presented in this work. It is established here that huge GHT rise rate of 16.48 ZJ (Zeta Joules = 1021 Joules) after 1965/70 from about 2 ZJ before 1960 is due to an un-natural, un-scientific and un-logical human reversal of one of these roles. Henceforth, almost all the Global Hazards and Calamities are being continuously nourished by this huge co...
