One of the most important problems in horticultural seed science and technology nowadays is looking for new methods to improve seed quality. Especially interesting are the ones, in which compounds of natural origin are used. One of such groups is ethereal oils from plants. The commercial seed samples of lettuce (Lactuca sativa L. ‘Dumka’) were soaked in 9 different treatments of 5% alcoholic solution of camphor tree (Cinnamomum camphora L.) ethereal oil and 9 different treatments of 5% alcoholic solution of patchouli plant (Pogostemon cablin Benth.) ethereal oil. Then the seeds were routinely tested for seed germination, the length of the received seedlings was also measured and the seeds health status was evaluated. The tested ethereal oils had no effect on the germination of lettuce seeds. However, soaking the seeds in the ethereal oils solutions did decrease the percentage of dead seeds in the tested samples. Soaking of the seeds in the ethereal oils solutions also increased the percentage of healthy ungerminated seeds. Treating the seeds with the concentrations of the ethereal oils solutions, although had no effect on their germination, still shortened the length of seedlings. Moreover, the used ethereal oils lowered the amount of identified Alternaria alternata and Cladosporium sphaerospermum fungi on the seeds.

Wastewater recycling technologies have been widely used in tanneries to reduce environmental impacts. However, only a few recycling methods have been developed for vegetable tanning processes due to limited knowledge of their wastewaters. In this study, the structures of the polyphenols in the larch tanning wastewater (LTW) and commercial larch tannin (CLT) were characterized with spectrographic and chromatographic analysis. Structures of these polyphenols were illustrated accordingly; their collagen reaction abilities were then tested with thermal analysis and visualized with a molecular docking software. Results showed that polyphenols in LTW and CLT were all procyanidins. However, average molecular weight of the polyphenols in LTW was 1104Da, in contrast to an obviously higher value for the CLT sample (3334Da). Meanwhile, the LTW presented obvious lower reactivity in the collagen-polyphenol reaction, including lower thermal stabilities and docking energies, fewer hydrogen bonds, and lower interaction energies. These results provide a hint for vegetable tanning wastewater recycling: because of these structural differences, reactivity of the polyphenols in wastewater are lower than the ones in commercial tannins. Therefore, before the recycling processes, polyphenols must be chemically modified in accordance with these structural differences.

Ecological networks have been considered to be an effective strategy to counter habitat fragmentation, which is occurring in the urbanization context. Researchers and planners have begun to integrate ecological networks in both thematic planning and urban or regional planning for biodiversity conservation and sustainable development. In this paper, we integrated the least-cost path model, network structure analysis, and gravity model to construct a regional ecological network of Poyang Lake Eco-economic Region, China. The least-cost model was improved by integrating three resistance factors, including land cover, slope, and human-induced pressure into it, presenting the landscape characteristics comprehensively in corridor simulation. The network structure analysis was employed to assess the proposed ecological network and the gravity model was used to identify the relative significance of network elements. Results indicated that the proposed hierarchical ecological network has good circuitry, complexity, and connectivity. Spatial analysis of prioritized network elements and breaking points revealed the regional connectivity condition, presenting significant reference to decision making in both land-use management and network implementation. Our study demonstrated that the integrated methodology is effective in regional ecological network planning and shows feasibility to be applied to other regions.

Parental lines are propagated in vitro in asparagus breeding. Additionally, in order to obtain super males which are needed for breeding all-male hybrids, anther culture is applied. Healthy and viable asparagus parental plants developed from in vitro culture should contain well formed storage roots. There are many factors affecting asparagus rooting. Only with the healthy explant materials, proper culture medium and growth conditions can asparagus plantlets be produced and later successfully grown in the greenhouse. In this article, obstacles and factors affecting asparagus rooting in vitro as well as trends in developing rooting technique are summarized.

The upper Eocene Youganwo Formation in Maoming Province, Guangdong Province, China, produced abundant remains of turtles and crocodiles, but mammalian remains are rare. The previously found mammals from Youganwo Formation include a nimravid carnivore and an amynodontid perissodactyl. Here we report on a new brontotheriid perissodactyl from the Youganwo Formation. Maobrontops paganus gen. et sp. nov. is described based on a maxillary fragment with P4 and M1–2 (SYSU-M-4). Maobrontops paganus gen. et sp. nov. is characterized by the combination of a simple P4 without a hypocone with derived molars having large molar fossae and large anterolingual cingular cusp. A parsimony implied weighting character analysis places Maobrontops gen. nov. in the clade Embolotheriita as a sister taxon to the terminal subclade containing Nasamplus, Protembolotherium, and Embolotherium. Maobrontops paganus gen. et sp. nov. is one of the largest Asian brontotheres. The brontotheriid fauna of South China is endemic and includes at least three valid taxa: Dianotitan from Brontotheriita and Pygmaetitan and Maobrontops gen. nov. from Embolotheriita.

H-FABP and A-FABP genes are considered as candidates for intramuscular fat (IMF) accretion. The aim of the present study was to assess the expression of H-FABP and A-FABP genes in m. longissimus dorsi (LD) and liver tissues of Laiwu and Lulai Black pig populations of different body weight (BW). Eighty-four barrows at different BW (30, 40, 50, 60, 70, 80, 90 and 100 kg, n06 per group) of Laiwu Black pig (no 100 kg group) and Lulai Black pig (no 30 kg group) were used to study the development changes of A-FABP and H-FABP mRNA expression and their relationships to IMF content. The results showed that, in both breeds, the IMF content increased continuously with growing (P< 0.05). The expression of H-FABP and A-FABP genes also increased with growing in LD tissue (P<0.05), and reached a peak at 50 and 70 kg BW in Laiwu and Lulai Black pig, respectively. However, this regularity was not observed in liver tissue in both breeds. A positive correlation was just found between the A-FABP mRNA expression level in LD tissue and IMF content and BW in both breeds (P<0.05). In conclusion, the A-FABP gene is strongly related to the development and function of IMF accretion in pigs.

As a waste of the fish processing industry, scales cause the disposal of large amounts of solid waste into the environment. How to turn such waste into a useful product is an important issue. In this study, acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC) were extracted from silver carp (Hypophthalmichthys molitrix) scales using a new acid-enzyme combined method. The results showed that the extraction yields of ASC and PSC were 5.09% and 12.06%, respectively. Then amino acid analysis, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), Fourier transform infrared spectroscopy (FT-IR), circular dichroism (CD) and ultra-sensitive differential scanning calorimetry (US-DSC) were used to study their composition, properties and structure. Amino acid analysis indicated that ASC and PSC were type I collagens with 34% glycine and 20% imino acid (Pro and Hyp). The results of SDS-PAGE and FT-IR analysis showed that ASC and PSC were similar to those of the standard type I collagen. CD indicated that the triple helical structure of both ASC and PSC were still retained. And the transition from triple helix to random coil of ASC and PSC were 34.26ºC and 34.47ºC, respectively. For the first time, the collagen yields of silver carp scales were calculated. Meanwhile, their composition, properties and structure were characterized. These results may offer theoretical support for the development of silver carp scales related to reusing technology to control waste.

Under the bad sea conditions and weak Beidou navigation signal environment, it is difficult to locate the ship on the sea, and the Beidou navigation system can’t work well. Beidou pseudolite system can improve the performance of Beidou navigation system as a navigation signal transmitter fixed on the ground, the signal of which can improve satellite positioning constellation structure, and improve the system availability reliability and precision. In order to ensure the interoperability and non-correlation of the Beidou pseudolite and the Beidou navigation system, the pseudolite ranging-codes should be selected in the same code space of the satellite ranging-codes and the residual pseudo random code generated by the 2 taps design scheme does not satisfy the performance requirements of the ranging-codes. To solve this issue, a combined design scheme with 3 taps is proposed, and 12 kinds of pseudolite ranging-codes are optimally selected according to the optimum design parameters of ranging-codes. The waveform and correlation of the selected pseudolite ranging-codes are analyzed by MATLAB, the acquisition simulation is carried out by using the new pseudolite ranging-codes. The experimental results show that the new 3-taps based ranging codes design scheme behaves a good balance, correlation and spectral characteristics

Cadmium (Cd) is regarded as one of the most toxic environmental pollutants. A better understanding of the growth response, uptake, and translocation of Cd in barnyard grass (Echinochloa crus-galli) would be helpful for evaluating the role of this grass species as a potential candidate to be used for phytoremediation. The studied plants were grown in treated soils with increasing doses of Cd (0, 0.3, 0.6, 0.9, and 1.5 mg·kg⁻¹). The results showed that Cd contents in plant tissues were found to increase with increasing doses of Cd. The pattern of Cd accumulation in different parts of the plant were found as: root > aboveground part > seed. Translocation factor (TF) values were found to be less than 1, and translocation from root to aboveground part was found to be higher as compared to that of aboveground part to seed. There was no significant difference on the aboveground part fresh weight (FW) and tiller number per plant under different concentrations of Cd stress. The root FW and the lengths of roots and shoots were significantly decreased in response to Cd treatments at low concentrations. However, the 1.5 mg·kg⁻¹ Cd application didn’t affect significant changes on the root and shoot length than that of the control. A high concentration of cadmium supply could promote chlorophyll content. SOD showed a similar trend to POD in Cd-exposed plants, with an increase at lower concentrations and a decrease at higher concentrations.

Impacts of dissolved oxygen (DO) and initial sludge concentrations on aerobic digestion for sewage sludge treatment were studied without adding alkalis. The MLVSS removal efficiencies were 50% and 47% in 20 days when DO concentrations were about 5.0 and 7.0 mg/L, respectively. Value of pH increased slightly in the first 6 days and then dropped constantly. The decrease of MLVSS appeared first quick back slow trend during the process and the OUR declination was similar. At the same DO level of 5.0 mg/L, the lower initial sludge concentration favored the efficiency of sludge stabilization. Both TN and TP of the supernatant were continually increasing and the ultimate concentrations were three to four times the initial concentrations. Results obtained from the present work could provide basic information for the aerobic sludge treatment process.

The adsorption behavior and the adsorption mechanism of the persistent organic pollutant DDT existing extensively in soils around the world are the key to solve the DDT-contaminated soils. Hence, in this paper, selective extraction and batch experimental method were used to examine the adsorption of DDT on farmland soils H and S in Northeast China. Simultaneously, the parameters indicating soil properties and composition such as soil particle, organic matter, and minerals, ect. were analyzed. Results show that the shape and the best fitted model of adsorption isotherm of DDT in both soils were L-type and Freundlich model, respectively. Smaller soil particle had greater adsorption capacity to DDT. The effects of organic matter and minerals on the adsorption of DDT were related to the composition and the origin of organic matter and minerals. Both SiO2 and illite-montmorillorite mixed-layer could hardly adsorb DDT, and the iron oxides could adsorb DDT, while the function of manganese oxides was inhibitory of DDT adsorption. Organic matter had greater adsorption capacity to DDT than iron oxides. The adsorption capacity of the plant residues is the greatest, followed by the aromatic substances from the plant and the products from microbial degradation.
