Effects of Sowing Rate on Marginal Superiority and Yield of Wheat in Wheat-cotton Intercropping System

In the wheat-cotton intercropping system, total 6 sowing rates （187.5, 225.0, 262.5, 300.0, 337.5 and 375.0 kg/hm2） were arranged, and the effects of sowing rate on marginal superiority and yield of wheat were investigated. The re- sults showed that the effect of sowing rate on inner-line wheat was greater than that on side-line wheat; with the increased sowing rate, the marginal superiority of panicle number was reduced in overall, and the difference in panicle number be- tween inner and side lines was decreased from 9.0×10^5/hm2 （sowing rate of 187.5 kg/hm2） to 7.8×10^5/hm2 （sowing rate of 375.0 kg/hm2）; the marginal superiority of grains per spike was increased first and then reduced, and the largest difference in grains per spike between the inner and side lines reached 4.6 under the sowing rate of 300.0 kg/hm2; the marginal superiority of 1 000-grain weight and yield was gradually increased, and the largest difference in 1 000-grain weight between the inner and side lines reached 3.9 g under the sowing rate of 337.5 kg/hm2, and in yield reached 3 136.5 kg/hm2under the sowing rate of 375.0 kg/hm2. The effects of sowing rate on the three yield factors of intercropped wheat ranked as panicle number 〉 grains per spike 〉 1 000-grain weight. The appropriate sowing rate of wheat was 225.0-262.0 kg/hm2 in the wheat-cotton intercropping system.

Coupling Relationship between Transport Superiority Degree and Urbanization in Sichuan,China

Relationship between transport superiority degree and urbanization is not quantified enough in recent researches.Combined with coupling model and coupling coordination model,the spatial analysis technique was applied to quantitatively analyzing the relationship between transport superiority degree and comprehensive urbanization in eighteen prefecture-level cities in Sichuan from 2000 to 2011. An evaluation index system was constructed,and index weights were obtained using the variation coefficient method. The traffic volume was found to be the main factor contributing to transport superiority degree, and space urbanization was the primary factor influencing comprehensive urbanization. The coupling degree between transport superiority degree and urbanization( CU) was generally higher than the coupling coordination degree( DU) in 2000-2011. DUvaried more significantly than CU. In 2011, Sichuan was divided into five regional types. Based on the above observations, targeted recommendations were developed.

A Tragedy of Reason Superiority——An Analysis of “The Most Dangerous Game” in Textism

The Most Dangerous Game is a highly-trimmed short story,with well-knitted plot,deep-carved characters,suspense,symbols,ironies,etc.Beyond its elaborate form,it conveys far-reaching social and cultural values.This paper is an attempt to appreciate the story inside out,in which structural approach and cultural approach are employed.Parallels and contrasts in structure and the unique shifts and gaps in its narration are highlighted to explore the tradition of reason superiority in western culture and the doom it has brought to the world and to the people concerned.The First World War is the fighting between rational beings.Rationality,when brought to extremes,may lead to irrationality.The image of General Zaroff is a reflection of modern westerner who boasts to be rational being while killing his fellow beings in bloody wars.

Interactive Effect and Spatial Characteristics of Agricultural Development Level and Transport Superiority Degree in Main Grain-producing Areas of the Central Jilin Province,China

To investigate the spatial synergy between agricultural development level and transport superiority degree in grain-producing areas of the central Jilin Province and the driving mechanism between them,22 counties in the central Jilin Province were used as the research units to calculate agricultural development level and transport superiority degree using the entropy weighting method,weighted travel time and raster cost distance.The spatial econometric model was used to analyze the mechanism of the mutual influence between the two.The main conclusions are as follows.1)Agricultural development level around Changchun,the provincial capital city,and in the areas of Changchun-Jilin and Changchun-Gongzhuling is high,whereas the development level of the counties in the southwest is low.2)Transport superiority degree of each county has improved,the overall connectivity of the road networks has been optimized,and the level of transportation accessibility has shown the development trend of‘centralization’,exhibiting the characteristics of proximity diffusion.3)Locally,there is spatial heterogeneity in the mutual driving effects of the two,with six main patterns.4)The theoretical conditions of von Thunen’s agricultural location have changed under the conditions of market economy due to the improvement of the transport networks,the new model of agricultural development,and the changes of the market system.

An analytic hierarchy process(AHP)was employed to assess the applicability of 18 new and superior varieties of flowers in Hefei City flower border applications.A total of 12 indicators were selected from three distinct aspects of adaptability,ornamental characteristics and use traits,in order to establish a comprehensive evaluation model.The results demonstrate that grade I(J≥2.685)exhibits excellent application value,encompassing six species of plants,such asHydrangeamacrophylla‘Endless Summer’;grade II(2.684≤J≤2.420)is also of notable application value,encompassing five species of plants,such asCallistemonrigidus;grade III(2.419≤J≤2.615)is of average application value,including five species of plants,such asCrocosmiacrocosmiflora;grade IV(J≤2.16)is of relatively poor application value.The evaluation results may be utilized as a theoretical reference for the promotion of new and superior varieties in the flower border of Hefei.

Drug combination therapy:providing evidence of significant superiority of a combination of drugs compared to the single agents

Based on Jun-Chen-Zuo-Shi,traditional Chinese medicine has used mixtures of naturally occurring herbs for more than 2000 years.Since the last century,advances in omics and cell biology have greatly impacted on the increasing use of drug combination in modern medicine.The enhanced understanding of the biology of a disease as a disturbed system of interconnected molecular pathways which are more susceptible to the simultaneous action of several drugs,provides new opportunities for the rational development of combination therapies.Combination therapies exploit the chances for better efficacy,decreased toxicity,and reduced development of drug resistance and owing to these advantages,have become a standard for the treatment of several diseases and continue to represent a promising approach in indications of unmet medical need.

Evaluation on Terrain-Climate Superiority Degree at County Level in Yunnan Province

Terrain slope and climate zone(heat zone)are important factors affecting land use zoning and agricultural production layout in mountainous areas.Using"weight grade method",a quantitative index of comprehensively evaluating terrain slope and climatic(thermal)conditions in mountainous areas was proposed:terrain-climate superiority degree(TCSD),and TCSD,terrain superiority degree(TSD),and climate superiority degree(CSD)in 129 counties(cities and districts)of Yunnan Province were measured and analyzed.The results showed that TCSD in 50.39%of counties of Yunnan Province was relatively better(levels I and II),and TCSD in 38.76%of counties was moderate(level III),while TCSD in 10.85%of counties was relatively poorer(levels IV and V).

Comparative Orotomy of the Archean Superior,North China,and Phanerozoic Altaid Orogenic Systems Architecture

Geological maps encode vast amounts of data about rock types,ages,chemistry,orogenic architecture and deep-time history or different tectonic units,yet these are often difficult to extract because of the way different geologists portray their results at various scales.To understand orogenesis in 4D,it is essential to uniformly integrate map data,together with geophysical data and deep geochemical mapping(Wang et al.,2023).

Phase reconfiguration of heterogeneous CoFeS/CoNiS nanoparticles for superior battery-type supercapacitors

Developing advanced battery-type materials with abundant active sites,high conductivity,versatile morphologies,and hierarchically porous structures is crucial for realizing high-quality hybrid supercapacitors.Herein,heterogeneous FeS@NiS is synthesized by cationic Co doping via surface-structure engineering.The density functional theory(DFT)theoretical calculations are firstly performed to predict the advantages of Co dopant by improving the OH^(−)adsorption properties and adjusting electronic structure,benefiting ions/electron transfer.The dynamic surface evolution is further explored which demonstrates that CoFeS@CoNiS could be quickly reconstructed to Ni(Co)Fe_(2)O_(4)during the charging process,while the unstable structure of the amorphous Ni(Co)Fe_(2)O_(4)results in partial conversion to Ni/Co/FeOOH at high potentials,which contributes to the more reactive active site and good structural stability.Thus,the free-standing electrode reveals excellent electrochemical performance with a superior capacity(335.6 mA h g^(−1),2684 F g^(−1))at 3 A g^(−1).Furthermore,the as-fabricated device shows a quality energy density of 78.1 W h kg^(−1)at a power density of 750 W kg^(−1)and excellent cycle life of 92.1%capacitance retention after 5000 cycles.This work offers a facile strategy to construct versatile morphological structures using electrochemical activation and holds promising applications in energy-related fields.

Superior rectus/levator complex in acquired anophthalmic socket repaired with spheric implant—a computed tomography scan and topographic study

AIM:To determine whether the levator palpebrae superioris(LPS)/superior rectus(SR)muscle complex,can influence the position of the upper lid and fornix in acquired anophthalmic sockets.METHODS:This comparative non-randomized and non-interventional study included retrospective data of 21 patients with unilateral acquired anophthalmic sockets repaired with spheric implants.High-resolution computed tomography(CT)measurements of the LPM/SR muscle complex and clinical topographic position of the upper lid,superior and inferior fornix depth in primary gaze position were evaluated.Demographic data were presented as frequency and percentage proportions and quantitative variables comparing the socket measurements with the normal contralateral orbit was statistically analyzed using non-parametric tests considering P<0.05.RESULTS:The anophthalmic orbits had a significantly shorter LPS length(P=0.01)and significantly thicker SR(P=0.02)than the normal orbit.Lagophthalmos was present in anophthalmic sockets but not in normal orbits(P=0.002),while levator function was normal in both(P>0.05,all comparisons).The superior fornix depth was similar in the anophthalmic socket and the contralateral normal orbit(P=0.192)as well the inferior fornix depth(P=0.351).CONCLUSION:Acquired anophthalmic sockets repaired with spheric implants have shorter LPS,thicker SR,and more lagophthalmos than normal orbits.The relationship of the LPS and SR with other orbital structures,associated with passive or active forces acting in the final position of the lids and external ocular prosthesis should be further investigated.

Dynamic ultrasonography for optimizing treatment position in superior mesenteric artery syndrome:Two case reports and review of literature

BACKGROUND Superior mesenteric artery(SMA)syndrome is a rare cause of duodenal obstruction by extrinsic compression between the SMA and the aorta(SMA-Ao).Although the left lateral recumbent position is considered effective in the treatment of SMA syndrome,individual variations in the optimal patient position have been noted.In this report,we present two elderly cases of SMA syndrome that exhibited rapid recovery due to ultrasonographic dynamic evaluation of the optimal position for each patient.CASE SUMMARY Case 1:A 90-year-old man with nausea and vomiting.Following diagnosis of SMA syndrome by computed tomography(CT),ultrasonography(US)revealed the SMA-Ao distance in the supine position(4 mm),which slightly improved in the lateral position(5.7–7.0 mm)without the passage of duodenal contents.However,in the sitting position,the SMA-Ao distance was increased to 15 mm accompanied by improved content passage.Additionally,US indicated enhanced passage upon abdominal massage on the right side.By day 2,the patient could eat comfortably with the optimal position and massage.Case 2:An 87-year-old woman with vomiting.After the diagnosis of SMA syndrome and aspiration pneumonia by CT,dynamic US confirmed the optimal position(SMA-Ao distance was improved to 7 mm in forward-bent position,whereas it remained at 5 mm in the supine position).By day 7 when her pneumonia recovered,she could eat with the optimal position.CONCLUSION The optimal position for SMA syndrome varies among individuals.Dynamic US appears to be a valuable tool in improving patient outcomes.

Accidental placement of venous return catheter in the superior vena cava during venovenous extracorporeal membrane oxygenation for severe pneumonia: A case report

BACKGROUND Venovenous extracorporeal membrane oxygenation(V-V ECMO)has become an important treatment for severe pneumonia,but there are various complications during the treatment.This article describes a case with severe pneumonia success-fully treated by V-V ECMO,but during treatment,the retrovenous catheter,which was supposed to be in the right internal vein,entered the superior vena cava directly in the mediastinum.The ECMO was safely withdrawn after multidiscip-linary consultation.Our experience with this case is expected to provide a reference for colleagues who will encounter similar situations.CASE SUMMARY A 64-year-old man had severe pulmonary infection and respiratory failure.He was admitted to our hospital and was given ventilation support(fraction of inspired oxygen 100%).The respiratory failure was not improved and he was treated by V-V ECMO,during which the venous return catheter,which was supposed to be in the right internal vein,entered the superior vena cava directly in the mediastinum.There was a risk of massive mediastinal bleeding if the catheter was removed directly when the ECMO was withdrawn.Finally,the patient underwent vena cava angiography+balloon attachment+ECMO with-drawal in the operating room(prepared for conversion to thoracotomy for vascular exploration and repair at any time during surgery)after multidiscip-linary consultation.ECMO was safely withdrawn,and the patient recovered and was discharged.CONCLUSION Patients may have different vascular conditions.Multidisciplinary cooperation can ensure patient safety.Our experience will provide a reference for similar cases.

Unroofed coronary sinus,left-sided superior vena cava and mitral insufficiency:A case report and review of the literature

BACKGROUND Unroofed coronary sinus(UCS)is a rare subtype of atrial septal defect.It is frequently associated with a persistent left superior vena cava and is often part of a more intricate cardiac malformation.CASE SUMMARY This report describes a rare case of an adolescent patient with UCS featuring atrial situs solitus,absence of the right superior vena cava and a persistent left superior vena cava draining into the left atrium consistent with total unroofing of the coronary sinus.This was associated with concurrent severe mitral insufficiency secondary to redundant and prolapsing leaflets,and a substantial left-to-right shunt across the coronary sinus orifice.A comprehensive examination of the existing literature is included,shedding light on the diagnostic challenges of UCS and describing the available surgical options within the context of mitral valve surgery.CONCLUSION UCS is a complex condition requiring careful consideration of associated anomalies and a tailored surgical approach.

Meningioma originating from the superior petrosal vein without dural attachment:A case report

BACKGROUND Meningioma in the cerebellopontine angle(CPA)without dural attachment is extremely rare.We report a unique case of meningioma derived from the superior petrosal vein without dural attachment.CASE SUMMARY A 44-year-old right-handed woman presented with a two-month history of headache and tinnitus.Brain magnetic resonance imaging showed a well-defined contrast-enhancing lesion in the right CPA without a dural tail sign.Tumor resection was performed using a right retro sigmoid approach.A dural attachment was not seen at the tentorium or posterior surface of the petrous pyramid.The tumor was firmly adherent to the superior petrosal vein.The origin site was cauterized and resected with the preservation of the superior petrosal vein.A diagnosis of meningothelial meningioma was made.The patient’s headache and tinnitus gradually disappeared,and a recurrence was not observed five years after the surgery.CONCLUSION The rare occurrence of meningioma without dural attachment makes it difficult to determine dural attachment before surgery.The absence of dural attachment makes it easy to completely resect such tumors.Vessels related to tumors should be removed carefully,considering the possible presence of tumor stem cells in the microvessels.

Emergency rescue of a patient with hemorrhagic shock caused by superior mesenteric artery rupture:A case report

BACKGROUND Superior mesenteric artery(SMA)injuries rarely occur during blunt abdominal injuries,with an incidence of<1%.The clinical manifestations mainly include abdominal hemorrhage and peritoneal irritation,which progress rapidly and are easily misdiagnosed.Quick and accurate diagnosis and timely effective treatment are greatly significant in managing emergent cases.This report describes emergency rescue by a multidisciplinary team of a patient with hemorrhagic shock caused by SMA rupture.CASE SUMMARY A 55-year-old man with hemorrhagic shock presented with SMA rupture.On admission,he showed extremely unstable vital signs and was unconscious with a laceration on his head,heart rate of 143 beats/min,shallow and fast breathing(frequency>35 beats/min),and blood pressure as low as 20/10 mmHg(1 mmHg=0.133 kPa).Computed tomography revealed abdominal and pelvic hematocele effusion,suggesting active bleeding.The patient was suspected of partial rupture of the distal SMA branch.The patient underwent emergency mesenteric artery ligation,scalp suture,and liver laceration closure.In view of conditions with acute onset,rapid progression,and high bleeding volume,key points of nursing were conducted,including activating emergency protocol,opening of the green channel,and arranging relevant examinations with various medical staff for quick diagnosis.The seamless collaboration of the multidisciplinary team helped shorten the preoperative preparation time.Emergency laparotomy exploration and mesenteric artery ligation were performed to mitigate hemorrhagic shock while establishing efficient venous accesses and closely monitoring the patient’s condition to ensure hemodynamic stability.Strict measures were taken to avoid intraoperative hypothermia and infection.CONCLUSION After 3.5 h of emergency rescue and medical care,bleeding was successfully controlled,and the patient’s condition was stabilized.Subsequently,the patient was transferred to the intensive care unit for continuous monitoring and treatment.On the sixth day,the patient was weaned off the ventilator,extubated,and relocated to a specialized ward.Through diligent medical intervention and attentive nursing,the patient made a full recovery and was discharged on day 22.The follow-up visit confirmed the patient’s successful recovery.
