: Di tengah berkembang teori sains modern terkait gerhana, teori ini dihadapkan sebuah tantangan baru dengan kemunculan gerakan konspirasi penganut konsep bumi datar (Flat Earth) yang mengkritik berbagai konsep bumi, bulan, matahari dan gerhana sains modern. Mereka beranggapan bahwa Jarak dan ukuran bumi, bulan dan matahari versi sains modern yang telah di ajarkan disekolah-sekolah 500 tahun yang lalu sampai sekarang hanyalah sebuah “asumsi diatas asumsi tanpa bisa di buktikan secara ilmiah”. ketika jarak matahari dan bulan terhadap bumi berbeda dengan sains modern akan berdampak terhadap teori gerhana yang dibangunnya, flat earth mengungkap teori bahwa gerhana bukan terjadi karena masuknya bayang-bayang bulan melainkan ada benda langit selestial yang lain yang menutupi matahari. Jenis penelitian ini yaitu penelitian library research dengan dua pendekatan yakni pendekatan metode kualitatif dan pendekatan sudut pandang filsafat ilmu teori kebenaran. Oleh sebab itu penulis bertujuan untuk menelaah secara kritis pengembangan teori gerhana penganut flat earth. Dalam hal ini sejauh mana Penganut flat earth mendeskripsikan keselarasan matahari, bulan, bumi pada kejadian gerhana. dan menelaah teori gerhana tersebut menurut teori kebenaran pragmatis.

<p>Kakao merupakan salah satu komoditas unggulan sektor perkebunan Indonesia, namun saat ini produktivitasnya mengalami penurunan. Hal ini salah satunya diakibatkan umur tanaman yang tidak produktif lagi serta intensitas serangan hama dan penyakit yang tinggi. Permasalahan tersebut dapat diatasi dengan penanaman kembali dengan benih unggul yang memiliki potensi hasil tinggi. Pertumbuhan benih kakao dipengaruhi oleh unsur hara yang tersedia dalam media tanam, diantaranya unsur N, P, dan K. Tanah lapisan atas (top soil) merupakan media yang paling baik namun tidak selalu tersedia, sehingga pemanfaatan tanah lapisan bawah (sub soil) dapat menjadi alternatif dengan penambahan unsur hara N, P, dan K. Penelitian ini bertujuan mendapatkan dosis pupuk NPK yang tepat untuk memacu pertumbuhan benih kakao pada media sub soil. Penelitian dilaksanakan di Instalasi Penelitian dan Pengkajian Teknologi Pertanian (IP2TP) Sidondo. Benih kakao yang digunakan adalah ICCRI 08H. Rancangan yang digunakan adalah rancangan acak kelompok dengan enam taraf dosis NPK 16-16-16, yakni: 1) Kontrol atau dosis 2,5 g/benih (P0); 2) 10 g/benih (P1); 3) 12,5 g/benih (P2); 4) 15 g/benih (P3); 5) 17,5 g/benih (P4) dan 6) 20 g/benih (P5), dengan ulangan sebanyak empat kali. Pengamatan komponen pertumbuhan meliputi: tinggi tanaman, diameter batang, panjang akar, jumlah daun, dan bobot tanaman. Hasil penelitian menunjukkan bahwa pemberian pupuk NPK 16-16-16 dengan dosis 12,5 g/benih menghasilkan pertumbuhan benih kakao terbaik khususnya pada perkembangan pembentukan akar, namun dengan dosis 10 g/benih mampu meningkatkan pertubuhan tinggi tanaman, diameter batang, dan jumlah daun. Benih kakao yang dihasilkan dengan media sub soil memenuhi syarat untuk disalurkan.</p>

Published: December 2022

The third potash seam of the Starobinsky deposit is mainly mined using the layered mining technology. The essence of the technology lies in the advance excavation of the 4th sylvinite layer by the uppere lava and the joint excavation of layers 2, 2–3 and 3 by the lagging lower lava under the protection of the interlayer pack of rock salt 3–4 (ceiling) left in the goaf. The thickness of the ceiling in accordance with the requirements of the regulatory document should be at least 0.8 m. At the same time, in the mine field of the mine of the Third Mine Administration, there are areas with a ceiling thickness reduced to 0.66–0.70 m. The purpose of the author’s research was to determine the possibility of safe mining of the Third potash seam using the layered mining technology with a reduced thickness of the ceiling. In the course of a full-scale experiment, the geological structure and strength properties of the rocks of the ceiling, its stability in the bottomhole space and the intensity of loading of the bottomhole lining of the lower lavas have been studied in the paper. The research methods also included the analysis of literary sources and statistical processing of the obtained data. It has been established that a decrease in the thickness of the ceiling by 0.10–0.14 m from the required one does not have a significant effect on its strength, while it remains stable in the near-bottom space of the lower longwalls. The main indicators of the manifestation of rock pressure in the studied lower longwalls – the rate of increase of the bottomhole lining in the stope cycles and the lowering of the roof in the bottomhole space – did not exceed the similar indicators in the longwalls with the required thickness of the ceiling. The obtained data indicate the possibility of safemining of the Third potash seam using the layered excavation technology with the thickness of the interlayer rock salt pack 3–4 not less than 0.66 m. In this case, the bearing capacity of the bottomhole lining should be at least 550 kN/m2.
Methodology for Calculating Water Supply for Irrigation from Reservoirs of Multifunctional Purpose (on the Example of China and Belarus
Authors: Mikhnevich E. I. , Li Ziming 
Published: December 2022

Reservoirs with multifunctional purposes are the most widely used as sources of water for irrigation. In China, a large number of irrigation systems have been created using reservoirs as sources for flood prevention, irrigation, industrial and agricultural water supply. In Belarus, the Soligorsk, Lyuban, Petrovich, Pogost and other multifunctional reservoirs are used for irrigation. The useful (regulating) volume of a multifunctional reservoir consists of separate components calculated for each consumer in the basis of a hydrological and feasibility study. Thus, the useful volume of water intended for irrigation should provide the required irrigation capacity and capacity of the irrigation system. When determining the useful (regulating) volume of a multifunctional reservoir, the total water requirements for various purposes (water supply, irrigation, hydropower, etc.) are calculated. For each consumer, the required design supply is assigned and the appropriate method for determining water consumption is used. Reservoirs intended for water supply count on 95–97 % availability of runoff, and for irrigation purposes – on 75–80 % availability in zones of moderate and excessive moisture. In arid, desert and semi-desert regions of China, where lack of water in dry years can lead to large crop losses, irrigation reservoirs are expected to be 90–95 % secure. The volumes and costs of water in the reservoir for irrigation purposes must cover the needs of plants in water within the established time frame for the year of estimated availability. The paper provides a formula for determining the weighted average irrigation rate and the volume of water required for irrigation. A methodology is presented for calculating the useful volume of a reservoir intended for industrial water supply and irrigation, for which flow regulation is calculated for two supply of water consumption. A method is proposed for determining the flow rate of entrained sediments for various stages of their movement. A formula is presented for the total volume of suspended and bottom sediments entering the reservoir.

Abstract
Simultaneously manipulating adsorption thermodynamics/kinetics and site density to realize the efficient adsorption capability of single-atom materials was important for adsorption-related catalysis, separation or purification, but remained challenging. Taking adsorptive desulfurization as a model, we reported a simple protonation of pyridinic-N strategy that notably improved the adsorption capability of Cu-N-C for dibenzothiophene via the cation-π and Cu-S interaction. The pyridinic-NH+ both acted as adsorption site and modulated the N-ligand field to elongate Cu-N bond to enhance the bonding strength of single-atom Cu site for organosulfur via upshifting the d-band center, thereby causing a higher desulfurization capacity of Cu-N-C than its counterparts. Moreover, the protonation reconstructed the surface electric field of Cu-N-C to weaken the repulsion effect between Cu-N-C and dibenzothiophene, which along with the abundant porous channel accelerated mass transfer and accumulation of dibenzothiophene around adsorption sites. This endowed Cu-N-C with a 2.4~310-fold higher adsorption kinetics than most reported adsorbents, thus achieving a ultrafast decrease of sulfur level (<10 ppm) within 70s, notably outstripping that of Fe-N-C (~ 900s) and activated carbon (~ 1800s).

Abstract
Atlantic Forest broad-leaved trees of high timber value require canopy cover to become established. Therefore, at present, they are only harvested from native rainforests. Araucaria angustifolia (Bertol.) Kuntze is the only Atlantic Forest Gymnosperm; it requires high radiation to establish and is planted in monospecific stands. The main question was if the umbrella-shaped open canopy generated by A. angustifolia stands was enough to protect mid-successional timber species. We evaluated the establishment of Cabralea canjerana (Vell.) Mart under the canopy of A. angustifoliastands and we related growth with initial competition. In one stand, we measured environmental and physiological traits to evaluate seedling acclimation. C. canjerana establishment was successful in stands of different basal areas. Seven years after planting, C. canjerana plants reached a 12-meter height and 75% survived; the highest growth was observed with up to two A. angustifolia neighbors within a 5m radius. According to this evidence, it is possible to convert A. angustifolia even-aged stands to uneven-aged mixed stands. In this way, a valuable native timber species that requires canopy protection during the first years can be planted outside the rainforest. This is the first report of an uneven-aged mixed plantation of two Atlantic Forest timber species.
Lactoferrin feeding deficiency during lactation increases the risk of depression in adult mice by affecting microbiota-gut-brain axis development

Published: December 2022

Abstract
Background
Lactoferrin is an active protein in breast milk that plays an important role in the growth and development of infants and is implicated as a neuroprotective agent. The incidence of depression is currently increasing, and it is unclear whether the lack of lactoferrin during lactation affects the incidence of depression in adulthood.
Objectives
The purpose of our work was to investigate the effect of lactoferrin feeding deficiency during lactation on adult depression and related mechanisms.
Methods
Lactoferrin knockout mice provided lactoferrin-free milk to establish a lactoferrin feeding deficiency model during lactation. The chronic unpredictable mild stress (CUMS) depression model was established when the mice reached 9 weeks of age. Behavioural performance, serum indicators, and the microbiota, intestine, and hippocampus injury of the CUMS mice were investigated; RNA-seq of the small intestine and hippocampus, and gut microbiota compositions in 18-day-old lactoferrin-free mice were analysed; the development of the intestine and hippocampus and microbiota compositions in adult lactoferrin-free mice were also examined.
Results
Lack of lactoferrin feeding during lactation affected the barrier and innate immune functions of the intestine, disrupted the intestinal microflora, and led to neuroimmune dysfunction and neurodevelopmental delay in the hippocampus. When exposed to external stimulation, adult lactoferrin feeding-deficient mice presented with worse depression-like symptoms; the mechanisms involved were activation of the LPS–TLR4 signalling pathway in the intestine and hippocampus, reduced BDNF-CREB signalling pathway in hippocampus, increased abundance of depression-related bacteria, and decreased abundance of beneficial bacteria.
Conclusions
Overall, our findings reveal that feeding lactoferrin during lactation can reduce the risk of depression in adults. The mechanism is related to the regulatory effect of lactoferrin on the development of the "microbial–intestinal–brain" axis.

Published: December 2022

Abstract

Background:Mostpreviousstudies comparing etiological studies in infants with and without periventricular-intraventricular haemorrhage (PV-IVH) concluded that younger gestational age (GA) was associated with a higher prevalence rate of PV-IVH. However, only few studies have examined the risk factors associated with the severity of PV-IVH after removing the influence of GA.Therefore, we investigated the risk factors apart from GA for PV-IVH severity in preterm infants less than 32 weeks.Methods:This was a retrospective case-control study of preterm infants born in West China Second Hospital with PV-IVH between 2009 and 2018. PV-IVH was defined using cranial ultrasound screening. Preterm infants with PV-IVH were divided into mild and severe groups. Both groups were matched in a 1:1 ratio using propensity score calculated from GA. Variables were collected from infant–mother pairs. A stepwise forward multivariate logistic regression model was adopted to select factors that affected the severity of PV-IVH in preterm infants.Results:A total of 3,783 preterm infants with PV-IVH were included. The total incidence of PV-IVH in preterm infants was 15.58%, and the incidence of PV-IVH of grades I, II, III, and IV was 2.50%, 9.52%, 3.13%, and 0.42%, respectively. The mortality of mild and severe PV-IVH was 0.33% and 3.25%, respectively. We matched 315 infants with severe PV-IVH with 315 infants with mild PV-IVH. The results suggested that early-onset sepsis (odds ratio [OR] 2.50, 95% confidence interval [CI]: 1.50–4.16), thrombocytopenia (OR 2.37, 95% CI: 1.39–4.04), multiple gestations (OR 1.69, 95% CI: 1.15–2.49), invasive mechanical ventilation (OR 1.59, 95% CI: 1.10–2.31), and magnesium sulphate use (OR 1.46, 95% CI: 1.01–2.10) were associated with severe PV-IVH. Female sex (OR 0.65, 95% CI: 0.46–0.91) was a protective factor against severe PV-IVH.Conclusions: Early-onset sepsis, thrombocytopenia, multiple gestations, invasive mechanical ventilation, magnesium sulphate use, and male sex contributed to severe PV-IVH in preterm infants regardless of GA, these risk factors may combine to predict the incidence of PV-IVH in preterm infants.
