The paper is devoted to organization of adaptive operation in a transport node. As an example, the authors consider the Ust-Luga transport node that includes a marshalling station and six port stations. The adaptive interaction includes the following. The marshalling station is able to prepare transfer trains to port stations in two variants - with a detailed selection of car sets by berths and without it. In the first case, the marshalling station executes additional operations, but the delivery time reduces. In dependence to the situation car sets are prepared in one way or another. The paper suggests a model of adaptive interaction that selects an optimal variant for all conditions. The model can become a basis for creation of adaptive operation of the transport node.

<p><strong>Introduction</strong><strong>:</strong> Pancreatic injury is a rare case, caused by blunt or sharp trauma. Difficulty in making diagnose on pancreatic trauma cases are associated with high mortality, and the treatment can be either operative or conservatively. However, It is still unclear which treatment is more favorable.</p><p><strong>Case:</strong> We present 2 cases of Grade III pancreatic injury with stable hemodynamic who suffered bicycle accident. First case, 12-year-old boy complaining severe pain on the upper left abdomen (VAS 9-10) and get worsening by time, with vomiting. The patient underwent distal Pancreatectomy-Splenectomy. Second case, 8-year-old boy complaining of pain on the upper left abdomen (VAS 6-7) without extension on whole abdominal region with vomiting and fever. The patient was treated conservatively. In both cases, patient was discharged with improvement. However, about 3 months later patients who were treated conservatively developed into a pseudocyst.</p><p><strong>Conclusion:</strong> The selection of management in grade III pancreatic injury can be operative or conservative depending on clinical findings such as hemodynamic condition and the quality of abdominal pain. But the occurrence of pseudocysts pancreas is another surgical challenge.</p>

Opening an underground mine or part of it presents complex and responsible issue, which affects the economy and effectiveness of the mine operation. This paper presents a methodology for selecting the optimal variant for opening, the lead-zinc ore mine Toranica, Macedonia. Six variants of opening and haulage of ore and waste rocks in the deeper parts of the ore deposit have been considered. After the performed analysis, the optimal variant for opening and haulage for the Toranica mine was determined.

ABSTRACT: The Clearfield® rice production system is an effective management tool for weedy rice and other weeds in the direct-seeded rice culture. However, if farmers cultivating the Clearfield® rice disregard stewardship recommendations, the industry could face a problem of herbicide-resistant weedy rice which would occur through the selection of outcrosses. This study aimed to confirm imidazolinone-resistant weedy rice in Malaysia. The resistant weedy rice (R-WR) was found to be 67 fold more resistant to OnDuty® (premix of imazapic and imazapyr) than the susceptible weedy rice (S-WR) based on the GR50 values (rate that causes 50% inhibition of shoot growth). The Clearfield® rice cultivar was 32-fold more tolerant to OnDuty® than the S-WR. Furthermore, the R-WR was 54 and 89 fold more resistant to imazapic and imazapyr applied separately than the S-WR, respectively. The Clearfield® rice was 140- and 40-fold more tolerant to imazapic and imazapyr, respectively than the S-WR. The R-WR biotype was susceptible to non-selective herbicides glyphosate and glufosinate, as well as the selective graminicide quizalofop. Oxadiazon controlled the R-WR biotype, but pretilachlor was ineffective. The present study documented the first case of weedy rice that was cross-resistant to imazapic and imazapyr in Malaysian Clearfield® rice field.

Despite the well-known benefits of using standardized outcome measures (OMs) in clinical practice, a variety of barriers interfere with their use. In particular, rehabilitation therapists lack sufficient knowledge in selecting appropriate OMs. The challenge is compounded when working with people with multiple sclerosis (MS) owing to heterogeneity of the patient population and symptom variability in individual patients. To help overcome these barriers, the American Physical Therapy Association appointed the Multiple Sclerosis Outcome Measures Task Force to review and make evidence-based recommendations for OM use in clinical practice, education, and research specific to people with MS. Sixty-three OMs were reviewed based on their clinical utility, psychometric properties, and a consensus evaluation of the appropriateness of use for people with MS. We sought to illustrate use of the recommendations for two cases. The first case involves a 43-year-old man with new-onset problems after an exacerbation. The second case pertains to an outpatient clinic interested in assessing the effectiveness of their MS rehabilitation program. For each case, clinicians identified areas that were important to assess and various factors deemed important for OM selection. Criteria were established and used to assist in OM selection. In both cases, the described processes narrowed the selection of OMs and assisted with choosing the most appropriate ones. The recommendations, in addition to the processes described in these two cases, can be used by clinicians in any setting working with patients with MS across the disability spectrum.

The use of Alternative Technical Concepts (ATC) is becoming widespread in design-build transportation projects in the United States. According to Federal Highway Administration (FHWA) ATC is a request by a proposer (usually in design-build projects) to modify a contract requirement for gaining competitive advantage over competition. The owner, usually a state department of transportation, requires that the ATC provide a better or at least equal solution to the owner’s design requirements. In Design-Build (DB) projects, the ATC is usually proposed by a proposer during the Request for Proposal (RFP) process and is considered in the evaluation and selection of the proposers in conjunction with the Best Value (BV) method of selection. In this paper, the authors have focused on two case studies involving ATC implementation and negotiations with the Massachusetts Department of Transportation (MassDOT) highlighting advantages and disadvantages of using ATC in DB contracts. In each case, the nature of ATC and the approval process is discussed. In the first case, the approved ATCs provided the proposer with a clear advantage in winning a contract with the agency despite not being the low bidder. In the second case, the proposed and approved ATCs did not result in winning a contract despite being the low bidder.

Network navigation is one of the main problems in large communication networks. We propose a new routing strategy in which some smart nodes in networks deliver messages to next hops on the paths towards destinations according to Yan's algorithm while the other nodes just deliver messages randomly. We test our routing strategy in a large scale-free network. Simulations show that the average delivery time decreases with increase of number of smart nodes, while the maximal network capacity increases with number of smart nodes in the network. Moreover our strategy is much more efficient when employed with target selection than with random selection of the smart nodes.
