Abstract:
The effect of
sub-lethal treatments (40% and 80% of 24h LC50 in
AFP) of bait formulation of different plant derived
molluscicides on different enzyme activities in the nervous
tissue of snail Indoplanorbis exustus was studied. Snails
fed with sub-lethal concentration of different molluscicides
inside attractant food pellets (AFP) caused a significant
inhibition in acetylcholinesterase (AChE), acid/alkaline
phosphatase (ACP/ALP), lactic dehydrogenase (LDH) and Na+K+
ATPase activities in the nervous tissue of I. exustus.
Bait formulation technique can be used for the mechanical
control of the vector snails. Use of molluscicides in the
attractant food pellet (AFP) is one of the effective methods of
snail control. Attractant food pellets containing amino acid
proline and agar plus different concentrations of the
molluscicides Azadirachta indica bark powder,
Annona squamosa seed powder and their bio-active
components azadirachtin and acetogenin were tested for
molluscicidal activity upto 144h against the snail, I.
exustus. Active components of both the plant derived
molluscicides were highly toxic to I. exustus compared
with their crude forms.

什么是黑洞的霍金辐射？如何用经典理论解释黑洞发射霍金辐射？

【内容摘要】：黑洞的霍金量子辐射简称霍金辐射。
霍金对黑洞理论划时代的伟大贡献是提出了在黑洞视界半径Rb上有温度Tb，能发射量子辐射
mss。这是建立在热力学和量子力学的坚实的基础上的，是符合实际的理论。
由广义相对论得出的黑洞是一个怪物。一旦形成，它就只能吞噬外界能量-物质而膨胀长大，在宇宙中永不消亡。霍金的黑洞理论证明，黑洞会因发射霍金量子辐射而缩小消亡，使黑洞与宇宙中的任何物体和事物一样，具有生长衰亡的普遍规律。所以是霍金的黑洞的理论挽救了不切实际的相对论黑洞理论。但是霍金没有得出霍金辐射mss的公式，对其发射机理的解释却不能让人信服和恭维。霍金解释说，由于真空是大量的‘虚粒子对’不断快速产生和湮灭的真空海洋，就使得虚粒子对中的负粒子被黑洞捕获而正粒子留在外部世界显形，这就成为黑洞中正粒子逃出黑洞的原因。这种解释是在用无法证实的新物理概念来圆场。作者在本文中将用经典理论找出霍金辐射mss的正确公式（1d），并且论证：黑洞的霍金辐射就是直接从其视界半径上Rb逃到外界的，是从高温高能量场向低温低能量场的自然流动，是符合热力学定律的。

摘要：粒子物理迎来革命时刻，但21世纪的今天，欧核中心发现了希格斯粒子和超对称，却不敢承认它，或许在相当长一段时间内也不敢承认它，为什么？

Abstract:
In this paper we will
discuss that today’s the most popular web sites are suffering
from the server congestion, and they are getting thousands of
requests every second from the client. The heterogeneity and
complexity of services and applications provided by web server
systems is continuously increasing. Traditional web publishing
sites with most static contents have being integrated with
recent web commerce and transactional sites combining as dynamic
and secure by services. The most understandable way to cope with
growing service demand and application complexity is adding
hardware resources because replacing an existing machine with a
faster model provides only temporary relief from server
overload. The need to optimize the performance of Web services
is producing a variety of novel architectures.

从大型强子对撞机说中国梦 ---
非线性希格斯粒子数学讨论（13）

摘要：粒子物理迎来革命时刻，对探测器中捕获的撞击、散射、交换、吸引、排斥、衰变、嬗变和湮灭的基本粒子或粒子碎片雨，测定是何种粒子，能否像基因测序进行快速、低成本、高通量、全基因组那样测定作解读？这是未来科学的中国梦。而从“同位量”和“同位长”量子纠缠态格点谱图像，测量分析是何种基本粒子，其实对于研究科学的人来说，也类似“格点谱”。我们把这其中的“同位量”和“同位长”另类，称为“格啥族”，是有对比的意义的。这样既不影响大部队的前进，又能保留少数人的声音，因为说啥，他们也不听，不如让两者相比较而存在的好。

Participatory rural
appraisal (PRA) as new method for Research

Abstract:
Promising potentials include farmers’ own farming systems
research, alternatives to questionnaire surveys, monitoring,
evaluation and lateral spread by local people, empowerment of
the poorer and weaker, and policy review. Changes in personal
behavior and attitudes, and in organizational cultures, are
implied. PRA parallels and resonates with paradigm shifts in the
social and natural sciences, business management, and
development thinking, supporting decentralization, local
diversity, and personal responsibility.
Much of the spread of
participatory rural appraisal (PRA) as
an emerging family of approaches and methods has been lateral,
South-South, through experiential learning and changes in
behavior, with different local applications. Rapid spread has
made quality assurance a concern, with dangers from “instant
fashion”, rushing, formalism and ruts. Promising potentials
include farmers’ own farming systems research, alternatives to
questionnaire surveys, monitoring, evaluation and lateral spread
by local people, empowerment of the poorer and weaker, and
policy review.
