An exploratory research is conducted to examine the current situation and factors related to the mental health of students. A cross-sectional study was carried out on 295 students at a high school in Hanoi in 2023. This research, which employed the Strengths and Difficulties Questionnaire 25 items toolkit with a cut-off point of 15, revealed that a significant percentage of students have general mental health problems. Emotional symptoms account for the largest percentage of students, followed by prosocial behaviour, peer problems, conduct problems, and hyperactivity.

Ebook "Minimally processed foods: Technologies for safety, quality, and convenience" explores both the definition of minimally processed foods and the methods and technologies used to achieve the safety and nutritional value consumers demand. The safety and efficacy of minimal food processing depends on the use of novel preservation technologies. This book first examines what is meant by minimally processed foods, including fresh-cut, cooked-chilled, and part-baked products.

In this chapter, we examine some additional pricing considerations and approaches. Companies today face a fierce and fast-changing pricing environment. Value-seeking customers have put increased pricing pressure on many companies. Thanks to economic woes in recent years, the pricing power of the Internet, and value-driven retailers such as Walmart, today’s more frugal consumers are pursuing spend-less strategies. In response, it seems that almost every company has been looking for ways to cut prices.

This research focus on to presents of the MQL parameters optimization approach in which the multi-response outputs based on Taguchi's L9 orthogonal array method is used. During the turning AISI-1045 steel, the cutting temperature, the maximum of tool wear, and the surface roughness were measured. The MQL parameters which are ratio of soluble lubricant and water, pressure of spray head, flow volume of emulsion was simultaneously optimized by taking the multi-response outputs using Taguchi based grey relational analysis (GRA) into consideration.

Efforts towards species conservation are focused on declining populations with less emphasis on dominant species. This has resulted to a once dominant species in forest ecosystem becoming endangered or at the verge of extinction. The study examined woody plants composition and stand structure of Detarium woodland to ascertain the conservation need of the species and other woody plants in Pandam wildlife Park, Plateau State, Nigeria. Four sample plots (250x10m each) were randomly established across the Daterium woodland.

The objective of the present work is to use a suitable method that can optimize the process parameters like pulse on time (TON), pulse off time (TOFF), wire feed rate (WF), wire tension (WT) and servo voltage (SV) to attain the maximum value of MRR and minimum value of surface roughness during the production of a fine pitch spur gear made of copper. The spur gear has a pressure angle of 20⁰ and pitch circle diameter of 70 mm. The wire has a diameter of 0.25 mm and is made of brass.

The present study aimed to develop the predictive models of average tool-workpiece interface temperature in hard turning of AISI 1060 steels by coated carbide insert. The Response Surface Methodology (RSM) and Artificial Neural Network (ANN) were employed to predict the temperature in respect of cutting speed, feed rate and material hardness. The number and orientation of the experimental trials, conducted in both dry and high pressure coolant (HPC) nvironments, were planned using full factorial design. The temperature was measured by using the tool-work thermocouple.

Each of these conditions will result in lower than normal operating pressures. When there is a shortage of refrigerant, pressures will be lower than normal. However, the reduction in pressure may be so slight as not to be readily detected, other than by a loss of evaporating capacity and the longer running time of the unit. If the shortage is considerable, both suction and discharge pressures will be very low; if the system temperature control consists of a thermostat only, the unit will run continuously with poor refrigerating effect.

Every time I put a book online for free, I get emails from readers who want to send me donations for the book. I appreciate their generous spirit, but I'm not interested in cash do- nations, because my publishers are really important to me. They contribute immeasurably to the book, improving it, introducing it to audiences I could never reach, helping me do more with my work. I have no desire to cut them out of the loop. But there has to be some good way to turn that generosity to good use, and I think I've found it....

War, war, war. For me the beginning of the war was a torchlight tattoo on Salisbury Plain. It was held on one of those breathless evenings in July when the peace of Europe was trembling in the balance, and when most of us had a heartache in case--in case England, at this time of internal crisis, did not rise to the supreme sacrifice. It was just the night for a tattoo--dark and warm and still. Away across the plain a sea of mist was rolling, cutting us off from the outside world, and only a few pale stars lighted our stage from above. The field...

Pressures on European banks to deleverage increased towards the end of 2011 as funding strains intensified and regulators imposed new capitalisation targets. Many of these banks shed assets, both through sales and by cutting lending. However, this did not appear to weigh heavily on asset prices, nor did overall financing fall for most types of credit. This was because other banks, asset managers and bond market investors took over the business of European banks.

UNFPA responds to emergencies in a wide range of situations and settings. The need might be to reach women in a refugee camp to work only with men, or to find internally displaced persons who are dispersed throughout the local population. Conditions may be hostile or hospitable, politically charged or on the path to peace; they are never easy.

Don't let my severe words of caution scare you away from trying this- but do pay close attention to what you are doing because this is a delicate procedure. Check and adjust the guides on the band saw, then fit a wide blade onto it, ¾" is best. A wide blade is necessary because when the blade is cutting a full six inches or more, there is a lot of pressure against the blade and it can be flexed backward. This can cause the blade to buckle slightly, and then it wanders severely to one side or the other. A...

As the needle reached the prostatic capsule the plunger attached to the needle was drawn out creating a high vacuum system and simultaneously the needle was advanced through the abnormal nodule. This resulted in a small plug of tissue sharply cut within the needle. In order to cut off the tissue the needle was withdrawn 0.5-1 cm and advanced at a different angle ensuring negative pressure was maintained on the plunger whilst the needle was withdrawn to the prostatic capsule and only then the plunger was slowly released and disconnected from the needle.

Around the world, many fisheries are shared fisheries in the sense that a common fish stock is accessed by both commercial and non-commercial fishers. Non-commercial fishers can include recreational fishers, or customary fishers, or both. A prevalent problem in these fisheries is competition between commercial and non-commercial fishers for access to a resource that is subject to increasing utilisation pressure.

Metal cutting puts extreme demands on the tool and tool material through conditions of high forces, high contact pressures, high temperatures, and intense chemical attack by difficult to cut work materials. In addition, the tool geometry and cutting conditions in terms of sharp edges, cyclic engagement and presence of cutting fluid will add to the severity. Most often cutting tools are used close to their ultimate resistance against these loads, especially to the limiting thermal and mechanical stresses. ...
