introduction: necrotizing pancreatitis management is complex and varies significantly among clinicians. Minimally invasive approaches like transgastric necrosectomy via laparoscopy are emerging as effective treatment options. This case report underscores the technique’s efficacy, clinical outcomes, and role in reducing complications. clinical observation: A 59-year-old male with a history of smoking and alcoholism presented with severe abdominal pain, nausea, and vomiting. over the following weeks, he developed symptoms including asthenia, weight loss, and melena. Diagnostic workup revealed severe anemia and Balthazar E necrotizing pancreatitis, with significant intra-abdominal fluid collections and signs of infection. After initial conservative management, the patient underwent transgastric necrosectomy via laparoscopy due to deteriorating clinical status. The procedure involved removing necrotic tissue and performing a cystogastroanastomosis and jejunostomy. Postoperative care included fasting, parenteral nutrition, broad-spectrum antibiotics, and enzymatic replacement. The patient recovered well, with reduced necrotic tissue on follow-up imaging, and was discharged twelve days post-surgery [1]. conclusion: Transgastric necrosectomy by laparoscopy is a valuable first-line surgical option for patients with symptomatic necrotizing pancreatitis, particularly in cases without prior interventions. This minimally invasive technique helps reduce major complications and mortality, offering a less invasive alternative to traditional open necrosectomy. The multidisciplinary approach and careful postoperative management were crucial to the patient’s favorable outcome. The case highlights the potential of transgastric necrosectomy as an effective treatment strategy in managing complex pancreatitis cases, including those with associated duodenal perforation [2].

one of the conventional ways to improve the mechanical behavior of soils is to mix them with cementing agents such as cement, lime and fly ash. Recently, introduction to alternative materials or sub-products that can be adopted to improve the soil strength is of paramount importance. Therefore, the present study aims to investigate the effects of porosity(h), dry unit weight(gd) of molding, cement content(c)and porosity/volumetric cement content ratio(h/civ) or void/cement ratio on the unconfined compressive strength(quor UcS) of silty soileroof tile waste(RT) mixtures. Soil samples are molded into four different dry unit weights(i.e. 13 kn/m^3, 13.67 kn/m^3, 14.33 kn/m^3 and 15 kn/m^3) using 3%, 6% and 9%cement and 5%, 15% and 30% RT. The results show that with the addition of cement, the strength of the RT esoil mixtures increases in a linear manner. on the other hand, the addition of RT decreases quof the samples at a constant percentage of cement, and the decrease in porosity can increase qu. A dosage equation is derived from the experimental data using the porosity/volumetric cement content ratio(h/c_(iv)) where the control variables are the moisture content, crushed tile content, cement content and porosity.

Psychophysics of the hoverfly: categorical or continuous color discrimination?

There is increasing interest in flies as potentially important pollinators. Flies are known to have a complex visual system, in eluding 4 spectral classes of photoreceptors that con tribute to the perception of color. our current understanding of how color signals are perceived by flies is based on data for the blowfly Lucilia sp., which after being conditi oned to rewarded mono chromatic light stimuli, showed evidenee of a categorical color visual system. The resulting opponent fly color space has 4 distinct categories, and has been used to interpret how some fly pollinators may perceive flower colors. However, formal proof that flower flies (Syrphidae) only use a simple, categorical color process remains outstanding. in free-flying experiments, we tested the hoverfly Eristalis tenax, a Batesian mimic of the honeybee, that receives its nutrition by visiting flowers. Using a range of broadband similar-dissimilar color stimuli previously used to test color perception in pollinating hymenopteran species, we evaluated if there are steep changes in behavioral choices with continuously increasing color differences as might be expected by categorical color processing. our data revealed that color choices by the hoverfly are mediated by a continuous monotonic function. Thus, these flies did not use a categorical processing, but showed evidenee of a color discrimination function similar to that observed in several bee species. We therefore empirically provide data for the minimum color distanee that can be discriminated by hoverflies in fly color space, enabling an improved un derstandi ng of plant-poll in ator interactions with a non-model insect species.

Effects of lime addition on geotechnical properties of sedimentary soil in curitiba,Brazil

Journal of Rock Mechanics and Geotechnical Engineering 2018年第1期10卷 188-194页

作者： jair A.Baldovino Eclesielter B.Moreira Wagner Teixeira Ronaldo L.S.izzo Juliana L.Rose Department of civil construction Federal University of Technology-Paraná Campus Curitiba

The soil of the Guabirotuba geological formation（Paraná Basin, Brazil） has physico-mechanical properties which are not suitable for its utilization in pavement construction, in protection of hillsides and slopes, or as shallow foundation support. Treatment of this soil by lime addition would improve its usability. The present context intends to determine the ratio between the splitting tensile strength（q;）and the unconfined compressive strength（q;） of clayey soil in the metropolitan region of curitiba city,which has been treated with different lime contents and curing times. The control parameters evaluated include lime content（L）, curing time（t）, moisture content（w）, and ratio of porosity to volumetric lime content（η/L;）. it was observed that the q;/q;ratio is between 0.17 and 0.2 in relation to the curing time,and an exponential relation exists between them. Meanwhile, the unconfined compressive strength of lime-treated soil was found to be approximately four times the initial value.

Signal or cue: the role of structural colors in flower pollination

current Zoology 2019年第4期65卷 467-481页

Angle dependent colors, such as iridescenee, are produced by structures present on flower petals changing their visual appearanee. These colors have been proposed to act as signals for plantinsect communication. However, there is a paucity of behavioral data to allow for interpretations of how to classify these colors either as a signal or a cue when con sidering the n atural con ditions under which pollination occurs. We sampled flowers from 6 plant species across various viewpoints looking for changes in the visual appearanee of the petals. Spectral characteristics were measured with different instruments to simulate both the spectral and spatial characteristics of honeybee's vision. We show the presenee of color patches produced by angle dependent effects on the petals and the calyx of various species;however, the appearance of the angle dependent color patches significantly varies with viewpoint and would only be resolved by the insect eye at close distances. Behavior experiments with honeybees revealed that pollinators did not use angle dependent colors to drive behavior when presented with novel flower presentations. Results show that angle dependent colors do not comply with the requirements of a signal for plant-pollinator communication since the information transmitted by these colors would be unreliable for potential, free-flying pollination vectors. We thus classify angle dependent colors produced by micro- and ultra-structures as being a cue (a feature which has not evolved for communication), and observe no evidence supporting claims of these angle dependent colors having evolved as visual signal.
