Di dalam budidaya terdapat dua faktor penting yaitu olah tanah dan pemupukan. Secara umum olah tanah dapat dibedakan atas olah tanah intensif (OTI) dan olah tanah konservasi (OTK). Olah tanah intensif dilakukan dengan cara dicangkul minimal dua kali sedalam 0-20 cm, lalu permukaan tanah diratakan; dan olah tanah konservasi dilakukan dengan olah tanah seminimal mungkin. Pengolahan tanah yang intensif akan menghilangkan sisa tanaman yang dapat berperan sebagai mulsa organik dan sumber bahan organik yang menjadi tempat tumbuh dan berkembangnya biota tanah seperti cacing tanah. Penelitian ini bertujuan untuk mempelajari pengaruh olah tanah dan pemupukan nitrogen serta interaksinya terhadap populasi dan biomassa cacing tanah. olah tanah digunakan tiga olah tanah yaitu olah tanah intensif, olah tanah minimum, dan tanpa olah tanah. Penelitian dilaksanakan di kebun percobaan Politeknik Negeri Lampung pada bulan November 2018 sampai Februari 2019. Penelitian menggunakan Rancangan Acak Kelompok (RAK), yang disusun secara faktorial 2 x 3 dengan 4 kelompok yaitu faktor pertama perlakuan olah tanah terdiri dari olah tanah intensif (T1), olah tanah minimum (T2), dan tanpa olah tanah (T3) sedangkan faktor kedua aplikasi pemupukan, terdiri dari pemupukan (N2) dan tanpa pemupukan (N0). Data yang diperoleh dianalisis sidik ragam pada taraf 5% yang sebelumnya telah diuji homogenitas ragamnya dengan Uji Barlett dan aditifitasnya dengan Uji Tukey. Rata-rata nilai tengah diuji dengan uji BNT pada taraf 5%. Untuk mengetahui hubungan antara C-organik, kadar air tanah, suhu tanah, dan pH tanah dengan populasi dan biomassa cacing tanah yaitu dilakukan uji korelasi. Hasil penelitian pada kedalaman 0-15 cm, menunjukkan bahwa populasi cacing tanah pada perlakuan tanpa olah tanah lebih tinggi dibandingkan olah tanah intensif dan olah tanah minimum. Pada kedalaman 0-15 cm dan 15-30 cm, biomassa cacing tanah pada perlakuan tanpa olah tanah lebih tinggi dibandingkan olah tanah intensif dan minimum. Terdapat interaksi antara pengolahan tanah dan pemupukan N terhadap populasi dan biomassa cacing tanah.

Mechanical evaluation of a threaded interference interlocking mechanism for angle-stable intramedullary nailing
Authors: Hanlon John , Kim Stanley E. 
Published: June 2024

Abstract

OBJECTIVE
To assess the fatigue and load-to-failure mechanical characteristics of an intramedullary nail with a threaded interference design (TID) in comparison to a commercially available veterinary angle-stable nail with a Morse taper bolt design (I-Loc) of an equivalent size.

METHODS
10 single interlocking screw/bolt constructs of TID and I-Loc implants were assembled using steel pipe segments and placed through 50,000 cycles of simulated, physiologic axial or torsional loading. Entry torque, postfatigue extraction torque, and 10th, 25,000th, and 50,000th cycle torsional toggle were assessed. Each construct was then loaded to failure in the same respective direction as fatigue testing. Four complete constructs of each design were then assessed using a synthetic bone analog with a 50-mm central defect via nondestructive torsional and axial loading followed by axial load to failure.

RESULTS
All constructs were angle stable at all time points and withstood fatigue loading. Median insertional torque, extraction torque-to-insertion torque ratio, and torsional yield load were 33%, 33%, and 72.5% lower, respectively, for the TID interlocking screws. No differences in torsional peak load, torsional stiffness, axial yield load, axial stiffness, or axial peak load were identified. No differences in complete construct angle stability, torsional stiffness, axial peak load, axial stiffness, or axial yield load were identified.

CLINICAL RELEVANCE
The TID had an inferior torsional yield load when compared to I-Loc implants but generated angle stability and sustained simulated physiologic fatigue loading. The TID may be a suitable mechanism for generating angle stability in interlocking nails.

Abstract
This is an animal model study to investigate changes in hemostasis during endotoxemic shock and to determine whether the combination of inhaled nitric oxide (iNO) + intravenous hydrocortisone had an effect on clot formation and fibrinolysis. iNO selectively decreases pulmonary artery pressure, without affecting cardiac index or systemic vascular resistance; however, the results of studies on the possible consequences of iNO administration on coagulation are inconsistent and require further research. Thirty-four piglets were included. Administering endotoxin caused severe hypodynamic shock. Half of the animals received iNO (30 ppm) + hydrocortisone, starting 3 h after endotoxin infusion and continuing to the end of the study. All animals developed coagulation disorders, manifested by a tendency to hypocoagulation; at the same time, fibrinolysis was impaired. Coagulation and fibrinolysis disorders persisted after endotoxin infusion was discontinued, with worse severity in the animals that died before the study was terminated. Administering iNO + hydrocortisone did not cause further changes in coagulation and fibrinolysis parameters, either during or after the endotoxin challenge, suggesting that potential therapeutic interventions with iNO to lower pulmonary arterial pressure will not affect hemostasis.

Abstract
The aim of the present study was to determine the associations between the MICB genetic variability and the expression and the risk of development of post-transplant complications after allogeneic hematopoietic stem cell transplantation (HSCT). HSCT recipients and their donors were genotyped for two MICB polymorphisms (rs1065075, rs3828903). Moreover, the expression of a soluble form of MICB was determined in the recipients' serum samples after transplantation using the Luminex assay. Our results revealed a favorable role of the MICB rs1065075 G allele. Recipients with donors carrying this genetic variant were less prone to developing chronic graft-versus-host disease (cGvHD) when compared to recipients without any symptoms of this disease (41.41% vs. 65.38%, p = 0.046). Moreover, the MICB rs1065075 G allele was associated with a lower incidence of cytomegalovirus (CMV) reactivation, both as a donor (p = 0.015) and as a recipient allele (p = 0.039). The MICB rs1065075 G variant was also found to be associated with decreased serum soluble MICB (sMICB) levels, whereas serum sMICB levels were significantly higher in recipients diagnosed with CMV infection (p = 0.0386) and cGvHD (p = 0.0008) compared to recipients without those complications. A protective role of the G allele was also observed for the rs3828903 polymorphism, as it was more frequently detected among donors of recipients without cGvHD (89.90% vs. 69.23%; p = 0.013). MICB genetic variants, as well as serum levels of sMICB, may serve as prognostic factors for the risk of developing cGvHD and CMV infection after allogeneic HSCT.

Published: June 2024

Abstract
Fish distribution in the lagoon complex of Lake Nokoué and Porto-Novo Lagoon is poorly documented. The lagoon complex is of particular interest because of its contribution to the local supply of animal protein. The fish communities in the complex were studied monthly between January and December 2015 at six sampling sites using two sets of gillnets with varying mesh sizes. The study applied a non-linear self-organizing map (SOM) method to classify the sampling sites based on the composition of fish assemblages, and an index of indicator value (IndVal) was calculated for each species identified. In total, 58 species from 49 genera and 34 families were cataloged with 45 species observed in Lake Nokoué and 48 in the Porto-Novo Lagoon. Notably, 35 species were common to both water bodies. The analysis revealed a dominance of occasional continental (20.7%) and strict estuarine species (20.7%). The SOM analysis suggested a tripartite structure of the fish communities, largely influenced by the geographical positioning of the sampling sites. The IndVal method identified 28 indicator species in the typical assemblages delineated by the SOM approach. The study highlights the importance of these indicator species for the conservation efforts aimed at sustaining the ichthyofauna of the lagoon complex.
Preliminary rearing outcomes of Siberian sturgeon, Acipenser baerii Brandt, juveniles in autonomous hatching and rearing modules
Authors: Piotrowska Iwona , Kozłowski Michał 
Published: June 2024

Abstract
This study analyzed the rearing indicators of Siberian sturgeon (Acipenser baerii) juveniles reared in tanks of different shapes and at various stocking densities. Rearing was conducted in autonomous hatching and rearing modules. Fish of an average body weight of 47.3±1.0 g were divided into four experimental groups: CL, RL, CH, and RH, which differed in stocking density (20 specimens and 50 specimens) and tank shape (C – circular, R – rectangular). The experiment ran for 28 days. Two-factor analysis indicated that lower stocking density significantly affected the final body weight of juvenile Siberian sturgeon, while tank shape had no effect on growth. The results of the current study on rearing Siberian sturgeon juveniles indicated that tanks of different shapes can be applied, but faster growth was obtained at a lower stocking density.

Structural Breaks and Co-Movements of Bitcoin and Ethereum: Evidence from the COVID-19 Pandemic Period
Authors: Tekin Bilgehan 
Published: June 2024

Abstract
This study examined the structural breakdowns and co-movements of Bitcoin (BTC) and Ethereum (ETH) cryptocurrencies from the onset of the COVID-19 pandemic. The Bai-Perron test was used to determine the change in the mean and variance of the two principal actors regarding market capitalization in the cryptocurrency market. Wavelet coherence analysis was also used to detect the co-movements between BTC and ETH. As a result of the study, several similar breaks were seen in each BTC and ETH series. Only one break could be directly associated with the pandemic process. This means that the pandemic is internalized and normalized in the process. The wavelet coherence results indicate a strong positive dependency (dark warm colours) between BTC and ETH and in phase (in the same direction) in the short and long bandgaps.
The Side Effects of Macroprudential Policies on Economic Performance in the Arab Region
Authors: Obeid Rami 
Published: June 2024

Abstract
Macroprudential policy mainly aims to enhance financial stability and reduce the possibility of costly financial crises. However, to achieve this, macroprudential policy decisions may have some unintended side effects on economic growth. The paper provides an empirical framework for investigating potential side effects of macroprudential policy tools in developing countries. The results show that macroprudential policy decisions may lead to a decline in economic growth in developing countries, but the depth and efficiency of the financial sector may interact with macroprudential policy decisions to support economic environment stability. In the Arab region, the results differ compared to other developing countries, as the macroprudential policy interventions have a positive impact on economic growth, especially for the macroprudential tools that aim to enhance the resilience of the banking sector, while there is no effect of the cyclical macroprudential tools on economic growth.
